There are some benefits and potentially serious risks associated with complementary and alternative medicines (CAM) patients with heart failure (HF) may use to manage symptoms, the American Heart Association noted in a new scientific statement on the topic.

For example, yoga and tai chi can be helpful for people with HF, and omega-3 polyunsaturated fatty acids may also have benefits. However, there are safety concerns with other commonly used over-the-counter CAM therapies, including vitamin D, blue cohosh, and Lily of the Valley, the writing group said.

It’s estimated that roughly one in three patients with HF use CAM. But often patients don’t report their CAM use to their clinicians and clinicians may not routinely ask about CAM use or have the resources to evaluate CAM therapies, writing group chair Sheryl L. Chow, PharmD, told this news organization.

“This represents a major public health problem given that consumers are frequently purchasing these potentially dangerous and minimally regulated products without the knowledge or advice from a health care professional,” said Dr. Chow, of Western University of Health Sciences, Pomona, Calif., and University of California, Irvine.

The 27-page statement was published online in Circulation.
 

CAM use common in HF

The statement defines CAM as medical practices, supplements, and approaches that do not conform to the standards of conventional, evidence-based practice guidelines. CAM products are available without prescriptions or medical guidance at pharmacies, health food stores, and online retailers.

“These agents are largely unregulated by the [Food and Drug Administration] and manufacturers do not need to demonstrate efficacy or safety. It is important that both health care professionals and consumers improve communication with respect to OTC therapies and are educated about potential efficacy and risk of harm so that shared and informed decision-making can occur,” Dr. Chow said.

The writing group reviewed research published before November 2021 on CAM among people with HF.

Omega-3 polyunsaturated fatty acids (PUFAs), such as fish oil, have the strongest evidence among CAM agents for clinical benefit in HF and may be used safely by patients in moderation and in consultation with their health care team, the writing group said.

Research has shown that omega-3 PUFAs are associated with a lower risk of developing HF as well as improvements in left ventricular systolic function in those with existing HF, they pointed out.

However, two clinical trials found a higher incidence of atrial fibrillation with high-dose omega-3 PUFA administration. “This risk appears to be dose-related and increased when exceeding 2 g/d of fish oil,” the writing group said.

Research suggests that yoga and tai chi, when added to standard HF treatment, may help improve exercise tolerance and quality of life and decrease blood pressure.
 

Inconclusive or potentially harmful CAM therapies

Other CAM therapies for HF have been shown as ineffective based on current data, have mixed findings, or appear to be harmful. The writers highlighted the following examples:

• Overall evidence regarding the value of vitamin D supplementation in patients with HF remains “inconclusive” and may be harmful when taken with HF medications such as digoxin, calcium channel blockers, and diuretics.
• Routine thiamine supplementation in patients with HF and without clinically significant thiamine deficiency may not be efficacious and should be avoided.
• Research on alcohol varies, with some data showing that drinking low-to-moderate amounts (one to two drinks per day) may help prevent HF, while habitual drinking or consuming higher amounts is known to contribute to HF.
• The literature is mixed on vitamin E. It may have some benefit in reducing the risk of HF with preserved ejection fraction but has also been associated with an increased risk of HF hospitalization.
• Coenzyme Q10 (Co-Q10), commonly taken as a dietary supplement, may help improve HF class, symptoms, and quality of life, but it also may interact with antihypertensive and anticoagulant medication. Co-Q10 remains of “uncertain” value in HF at this time. Large-scale randomized controlled trials are needed before any definitive conclusion can be reached.
• Hawthorn, a flowering shrub, has been shown in some studies to increase exercise tolerance and improve HF symptoms such as fatigue. Yet it also has the potential to worsen HF, and there is conflicting research about whether it interacts with digoxin.
• The herbal supplement blue cohosh, from the root of a flowering plant found in hardwood forests, could cause tachycardia, high blood pressure, chest pain, and increased blood glucose. It may also decrease the effect of medications taken to treat high blood pressure and type 2 diabetes, they noted.
• Lily of the Valley, the root, stems, and flower of which are used in supplements, has long been used in mild HF because it contains active chemicals similar to digoxin. But when taken with digoxin, it could lead to hypokalemia.

In an AHA news release, Dr. Chow said, “Overall, more quality research and well-powered randomized controlled trials are needed to better understand the risks and benefits” of CAM therapies for HF.

“This scientific statement provides critical information to health care professionals who treat people with heart failure and may be used as a resource for consumers about the potential benefit and harm associated with complementary and alternative medicine products,” Dr. Chow added.

The writing group encourages health care professionals to routinely ask their HF patients about their use of CAM therapies. They also say pharmacists should be included in the multidisciplinary health care team to provide consultations about the use of CAM therapies for HF patients.

The scientific statement does not include cannabis or traditional Chinese medicine, which have also been used in HF.

In 2020, the AHA published a separate scientific statement on the use of medical marijuana and recreational cannabis on cardiovascular health, as reported previously by this news organization.

The scientific statement on CAM for HF was prepared by the volunteer writing group on behalf of the AHA Clinical Pharmacology Committee and Heart Failure and Transplantation Committee of the Council on Clinical Cardiology; the Council on Epidemiology and Prevention; and the Council on Cardiovascular and Stroke Nursing.

A new study has provided further reassurance on questions about the risk of intracerebral hemorrhage (ICH) with statins.

The Danish case-control study, which compared statin use in 2,164 case patients with ICH and in 86,255 matched control persons, found that current statin use was associated with a lower risk of having a first ICH and that the risk was further reduced with longer duration of statin use.

The study also showed that statin use was linked to a lower risk of ICH in the more superficial lobar areas of the brain and in the deeper, nonlobar locations. There was no difference in the magnitude of risk reduction between the two locations.

“Although this study is observational, I feel these data are strong, and the results are reassuring. It certainly does not suggest any increased risk of ICH with statins,” senior author David Gaist, PhD, Odense University Hospital, Denmark, said in an interview.

“On the contrary, it indicates a lower risk, which seems to be independent of the location of the bleed.”

The study was published online in Neurology.

The authors note that statins effectively reduce the occurrence of cardiovascular events and ischemic stroke in high-risk populations, but early randomized trials raised concerns of an increased risk of ICH among statin users who have a history of stroke.

Subsequent observational studies, including four meta-analyses, included patients with and those without prior stroke. The results were inconsistent, although most found no increase in bleeding. More recent studies have found a lower risk of ICH among statin users; the risk was inversely associated with the duration and intensity of statin treatment.

However, the researchers point out that few studies have assessed the association between statin use and the location of ICH. Hemorrhages that occur in the lobar region of the brain and those that occur in the nonlobar areas can have different pathophysiologies. Arteriolosclerosis, which is strongly associated with hypertension, is a common histologic finding in patients with ICH, regardless of hemorrhage location, while cerebral amyloid angiopathy (CAA) is associated with lobar but not nonlobar ICH.

The current study was conducted to look more closely at the relationship between statin use and hematoma location as a reflection of differences in the underlying pathophysiologies of lobar versus nonlobar ICH.

The researchers used Danish registries to identify all first-ever cases of spontaneous ICH that occurred between 2009 and 2018 in persons older than 55 years in the Southern Denmark region. Patients with traumatic ICH or ICH related to vascular malformations and tumors were excluded.

These cases were verified through medical records. ICH diagnoses were classified as having a lobar or nonlobar location, and patients were matched for age, sex, and calendar year to general population control persons. The nationwide prescription registry was also analyzed to ascertain use of statins and other medications.

The study included 989 patients with lobar ICH who were matched to 39,500 control persons and 1,175 patients with nonlobar ICH who were matched to 46,755 control persons.

Results showed that current statin use was associated with a 16%-17% relative reduction in ICH risk. There was no difference with respect to ICH location.

For lobar ICH, statin use showed an adjusted odds ratio of 0.83 (95% confidence interval, 0.70-0.98); for nonlobar ICH, the adjusted odds ratio was 0.84 (95% CI, 0.72-0.98).

Longer duration of statin use was associated with a greater reduction in risk of ICH; use for more than 5 years was associated with a relative reduction of ICH of 33%-38%, again with no difference with regard to ICH location.

For lobar ICH, statin use for more than 5 years showed an adjusted odds ratio of 0.67 (95% CI, 0.51-0.87); and for nonlobar ICH, the adjusted odds ratio was 0.62 (95% CI, 0.48-0.80).

“We suspected that statins may have more of an effect in reducing nonlobar ICH, as this type is considered to be more associated with arteriosclerosis, compared with lobar ICH,” Dr. Gaist explained. “But we didn’t find that. We found that taking statins was associated with a similar reduction in risk of both lobar and nonlobar ICH.”

Although amyloid angiopathy can contribute to lobar ICH, arteriosclerosis is still involved in the majority of cases, he noted. He cited a recent population-based U.K. study that showed that while histologically verified CAA was present in 58% of patients with a lobar ICH, most also had evidence of arteriosclerosis, with only 13% having isolated CAA pathology.

“If statins exert their effect on reducing ICH by reducing arteriosclerosis, which is likely, then this observation of arteriosclerosis pathology being prevalent in both lobar and nonlobar ICH locations would explain our results,” Dr. Gaist commented.

“Strengths of our study include the large numbers involved and the fact that the patients are unselected. We tried to find everyone who had had a first ICH in a well-defined region of Denmark, so issues of selection are less of a concern than in some other studies,” he noted.

He also pointed out that all the ICH diagnoses were verified from medical records and that in a substudy, brain scans were evaluated, with investigators masked to clinical data to evaluate the location and characteristics of the hematoma. In addition, data on statin use were collected prospectively from a nationwide prescription registry.
 

Interaction with antihypertensives, anticoagulants?

Other results from the study suggest a possible interaction between statin use and antihypertensive and anticoagulant drugs.

Data showed that the lower ICH risk was restricted to patients who received statins and antihypertensive drugs concurrently. Conversely, only patients who were not concurrently taking anticoagulants had a lower risk of ICH in association with statin use.

Dr. Gaist suggested that the lack of a reduction in ICH with statins among patients taking anticoagulants could be because the increased risk of ICH with anticoagulants was stronger than the reduced risk with statins.

Regarding the fact that the reduced risk of ICH with statins was only observed among individuals who were also taking antihypertensive medication, Dr. Gaist noted that because hypertension is such an important risk factor for ICH, “it may be that to get the true benefit of statins, patients have to have their hypertension controlled.”

However, an alternative explanation could that the finding is a result of “healthy adherer” bias, in which people who take antihypertensive medication and follow a healthy lifestyle as advised would be more likely to take statins.

“The observational nature of our study does not allow us to determine the extent to which associations are causal,” the authors say.

Dr. Gaist also noted that an important caveat in this study is that they focused on individuals who had had a first ICH.

“This data does not inform us about those who have already had an ICH and are taking statins. But we are planning to look at this in our next study,” he said.

The study was funded by the Novo Nordisk Foundation. Dr. Gaist has received speaker honorarium from Bristol-Myers Squibb and Pfizer unrelated to this work.

Longer duration of statin use was associated with a greater reduction in risk of ICH; use for more than 5 years was associated with a relative reduction of ICH of 33%-38%, again with no difference with regard to ICH location.

For lobar ICH, statin use for more than 5 years showed an adjusted odds ratio of 0.67 (95% CI, 0.51-0.87); and for nonlobar ICH, the adjusted odds ratio was 0.62 (95% CI, 0.48-0.80).

“We suspected that statins may have more of an effect in reducing nonlobar ICH, as this type is considered to be more associated with arteriosclerosis, compared with lobar ICH,” Dr. Gaist explained. “But we didn’t find that. We found that taking statins was associated with a similar reduction in risk of both lobar and nonlobar ICH.”

Although amyloid angiopathy can contribute to lobar ICH, arteriosclerosis is still involved in the majority of cases, he noted. He cited a recent population-based U.K. study that showed that while histologically verified CAA was present in 58% of patients with a lobar ICH, most also had evidence of arteriosclerosis, with only 13% having isolated CAA pathology.

“If statins exert their effect on reducing ICH by reducing arteriosclerosis, which is likely, then this observation of arteriosclerosis pathology being prevalent in both lobar and nonlobar ICH locations would explain our results,” Dr. Gaist commented.

“Strengths of our study include the large numbers involved and the fact that the patients are unselected. We tried to find everyone who had had a first ICH in a well-defined region of Denmark, so issues of selection are less of a concern than in some other studies,” he noted.

He also pointed out that all the ICH diagnoses were verified from medical records and that in a substudy, brain scans were evaluated, with investigators masked to clinical data to evaluate the location and characteristics of the hematoma. In addition, data on statin use were collected prospectively from a nationwide prescription registry.
 

Interaction with antihypertensives, anticoagulants?

Other results from the study suggest a possible interaction between statin use and antihypertensive and anticoagulant drugs.

Data showed that the lower ICH risk was restricted to patients who received statins and antihypertensive drugs concurrently. Conversely, only patients who were not concurrently taking anticoagulants had a lower risk of ICH in association with statin use.

Dr. Gaist suggested that the lack of a reduction in ICH with statins among patients taking anticoagulants could be because the increased risk of ICH with anticoagulants was stronger than the reduced risk with statins.

Regarding the fact that the reduced risk of ICH with statins was only observed among individuals who were also taking antihypertensive medication, Dr. Gaist noted that because hypertension is such an important risk factor for ICH, “it may be that to get the true benefit of statins, patients have to have their hypertension controlled.”

However, an alternative explanation could that the finding is a result of “healthy adherer” bias, in which people who take antihypertensive medication and follow a healthy lifestyle as advised would be more likely to take statins.

“The observational nature of our study does not allow us to determine the extent to which associations are causal,” the authors say.

Dr. Gaist also noted that an important caveat in this study is that they focused on individuals who had had a first ICH.

“This data does not inform us about those who have already had an ICH and are taking statins. But we are planning to look at this in our next study,” he said.

The study was funded by the Novo Nordisk Foundation. Dr. Gaist has received speaker honorarium from Bristol-Myers Squibb and Pfizer unrelated to this work.

Use of a tumor necrosis factor inhibitor (TNFi) or triple therapy with conventional, synthetic disease-modifying antirheumatic drugs (DMARDs) for rheumatoid arthritis have similar beneficial effects in reducing patients’ vascular inflammation and cardiovascular (CV) risk, according to results from a randomized, active comparator trial.

“The good news is, providers can rest assured that aggressive treatment for RA does reduce vascular inflammation and therefore cardiovascular risk,” lead author Daniel H. Solomon, MD, MPH, of Brigham and Women’s Hospital in Boston, told this news organization. “Part of the reason that treating people with potent disease-modifying agents is important is not only because of reductions in pain and improvements in function on the level of arthritis, but also because of the vascular impact.”

The small study, published in Annals of the Rheumatic Diseases, randomly assigned 115 patients with active RA despite methotrexate use to one of two treatment protocols for 24 weeks: addition of a TNFi or triple therapy with the addition of sulfasalazine and hydroxychloroquine. Participants had 18F-fluorodeoxyglucose (FDG)–PET/CT scans at baseline and 24 weeks to assess change in arterial inflammation, measured as an arterial target-to-background ratio (TBR) in the carotid arteries and aorta. The study achieved its outcomes despite a low 56.5% rate of adherence to 80% or more of randomized treatments.

Dr. Solomon said this is the first randomized trial comparing the effects of DMARDs on vascular inflammation in RA. The researchers hypothesized that TNFi would be superior to triple therapy for reducing vascular inflammation. “We found that they both reduced vascular inflammation on PET scanning to the same degree,” Dr. Solomon said.

Study results

In the TNFi group, the mean of the maximum of the TBR in the most diseased segment (MDS) of the index vessel declined from 2.72 to 2.47 for a delta of –0.24. In the triple-therapy patients, MDS declined from 2.62 to 2.43 for a delta of –0.19 (difference in deltas –0.02; 95% confidence interval, –0.19 to 0.15; P = .79).

Dr. Solomon explained the choice of FDG-PET/CT scanning to evaluate vascular inflammation in the study participants. “We know that FDG-PET/CT scanning correlates with CV risk, and we know that treatments like statins that impact CV risk reduce the inflammation as observed on FDG-PET/CT,” he said.

Although the study found no difference between the TNFi and triple therapy in terms of vascular outcomes, the conclusion is “a bit more nuanced,” Dr. Solomon said. “It tells us first that reducing inflammation with different strategies in rheumatoid arthritis can similarly impact vascular inflammation. That’s great news. These are aggressive treatment strategies, so if you can reduce vascular inflammation in a significant manner, that should result in reduced cardiovascular risk over time.” 

Although the choice of TNFi or triple therapy may not matter for reducing CV risk, Dr. Solomon said, “It matters that you choose something that’s aggressive and that you use it in people who have active disease. That’s another part of the story: People who have active disease have worse vascular inflammation, which translates into a reduction in cardiovascular risk – but it’s not differentially reduced.”

Underlying mechanisms of CVD in RA

Commenting on the research for this news organization, Lihi Eder, MD, PhD, codirector of the cardio-rheumatology program at Women’s College Hospital in Toronto, said the study findings build on what’s known about some of the underlying mechanisms of cardiovascular diseases in RA and how to optimize treatments to reduce the risk.

“Importantly,” she said, “none of these treatment strategies was superior, suggesting that both treatment options are acceptable when considering cardiovascular risk reduction, in addition to controlling RA activity.”

The strengths of the study are its randomized, controlled design “conducted by a strong team of investigators,” and that it addressed questions relevant to routine practice, said Dr. Eder, who was not involved with the study.

The study’s use of FDG-PET/CT as a surrogate outcome is a limitation, she noted. “Although it would have been very challenging to perform a similar study that will include clinical events as a study outcome.” Another limitation, she said, was the low adherence rate to randomized treatments.

“Additional studies that will compare other modes of action [for example, interleukin-6 inhibitors, Janus kinase inhibitors, anti-CD20 monoclonal antibodies] could broaden our understanding regarding the inflammatory pathways driving CV risk in RA,” Dr. Eder added.

The study received funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases. AbbVie and Amgen supplied drugs used in the study. Dr. Solomon disclosed receiving research support from AbbVie, Amgen, CorEvitas, and Moderna, and royalties from UpToDate. Dr. Eder reports no relevant financial relationships.

Most of us have two voice changes in our lifetime: First during puberty, as the vocal cords thicken and the voice box migrates down the throat. Then a second time as aging causes structural changes that may weaken the voice.

But for some of us, there’s another voice shift, when a disease begins or when our mental health declines.

This is why more doctors are looking into voice as a biomarker – something that tells you that a disease is present.

Vital signs like blood pressure or heart rate “can give a general idea of how sick we are. But they’re not specific to certain diseases,” says Yael Bensoussan, MD, director of the University of South Florida, Tampa’s Health Voice Center and the coprincipal investigator for the National Institutes of Health’s Voice as a Biomarker of Health project.

“We’re learning that there are patterns” in voice changes that can indicate a range of conditions, including diseases of the nervous system and mental illnesses, she says.

Speaking is complicated, involving everything from the lungs and voice box to the mouth and brain. “A breakdown in any of those parts can affect the voice,” says Maria Powell, PhD, an assistant professor of otolaryngology (the study of diseases of the ear and throat) at Vanderbilt University, Nashville, Tenn., who is working on the NIH project.

You or those around you may not notice the changes. But researchers say voice analysis as a standard part of patient care – akin to blood pressure checks or cholesterol tests – could help identify those who need medical attention earlier.

Often, all it takes is a smartphone – “something that’s cheap, off-the-shelf, and that everyone can use,” says Ariana Anderson, PhD, director of the University of California, Los Angeles, Laboratory of Computational Neuropsychology.

“You can provide voice data in your pajamas, on your couch,” says Frank Rudzicz, PhD, a computer scientist for the NIH project. “It doesn’t require very complicated or expensive equipment, and it doesn’t require a lot of expertise to obtain.” Plus, multiple samples can be collected over time, giving a more accurate picture of health than a single snapshot from, say, a cognitive test.

Over the next 4 years, the Voice as a Biomarker team will receive nearly $18 million to gather a massive amount of voice data. The goal is 20,000-30,000 samples, along with health data about each person being studied. The result will be a sprawling database scientists can use to develop algorithms linking health conditions to the way we speak.

For the first 2 years, new data will be collected exclusively via universities and high-volume clinics to control quality and accuracy. Eventually, people will be invited to submit their own voice recordings, creating a crowdsourced dataset. “Google, Alexa, Amazon – they have access to tons of voice data,” says Dr. Bensoussan. “But it’s not usable in a clinical way, because they don’t have the health information.”

Dr. Bensoussan and her colleagues hope to fill that void with advance voice screening apps, which could prove especially valuable in remote communities that lack access to specialists or as a tool for telemedicine. Down the line, wearable devices with voice analysis could alert people with chronic conditions when they need to see a doctor.

“The watch says, ‘I’ve analyzed your breathing and coughing, and today, you’re really not doing well. You should go to the hospital,’ ” says Dr. Bensoussan, envisioning a wearable for patients with COPD. “It could tell people early that things are declining.”

Artificial intelligence may be better than a brain at pinpointing the right disease. For example, slurred speech could indicate Parkinson’s, a stroke, or ALS, among other things.

“We can hold approximately seven pieces of information in our head at one time,” says Dr. Rudzicz. “It’s really hard for us to get a holistic picture using dozens or hundreds of variables at once.” But a computer can consider a whole range of vocal markers at the same time, piecing them together for a more accurate assessment.

“The goal is not to outperform a ... clinician,” says Dr. Bensoussan. Yet the potential is unmistakably there: In a recent study of patients with cancer of the larynx, an automated voice analysis tool more accurately flagged the disease than laryngologists did. 

“Algorithms have a larger training base,” says Dr. Anderson, who developed an app called ChatterBaby that analyzes infant cries. “We have a million samples at our disposal to train our algorithms. I don’t know if I’ve heard a million different babies crying in my life.”

So which health conditions show the most promise for voice analysis? The Voice as a Biomarker project will focus on five categories.
 

Voice disorders (cancers of the larynx, vocal fold paralysis, benign lesions on the larynx)

Obviously, vocal changes are a hallmark of these conditions, which cause things like breathiness or “roughness,” a type of vocal irregularity. Hoarseness that lasts at least 2 weeks is often one of the earliest signs of laryngeal cancer. Yet it can take months – one study found 16 weeks was the average – for patients to see a doctor after noticing the changes. Even then, laryngologists still misdiagnosed some cases of cancer when relying on vocal cues alone.

Now imagine a different scenario: The patient speaks into a smartphone app. An algorithm compares the vocal sample with the voices of laryngeal cancer patients. The app spits out the estimated odds of laryngeal cancer, helping providers decide whether to offer the patient specialist care.

Or consider spasmodic dysphonia, a neurological voice disorder that triggers spasms in the muscles of the voice box, causing a strained or breathy voice. Doctors who lack experience with vocal disorders may miss the condition. This is why diagnosis takes an average of nearly 4.5 years, according to a study in the Journal of Voice, and may include everything from allergy testing to psychiatric evaluation, says Dr. Powell. Artificial intelligence technology trained to recognize the disorder could help eliminate such unnecessary testing.
 

Neurological and neurodegenerative disorders (Alzheimer’s, Parkinson’s, stroke, ALS) 

For Alzheimer’s and Parkinson’s, “one of the first changes that’s notable is voice,” usually appearing before a formal diagnosis, says Anais Rameau, MD, an assistant professor of laryngology at Weill Cornell Medicine, New York, and another member of the NIH project. Parkinson’s may soften the voice or make it sound monotone, while Alzheimer’s disease may change the content of speech, leading to an uptick in “umms” and a preference for pronouns over nouns.

With Parkinson’s, vocal changes can occur decades before movement is affected. If doctors could detect the disease at this stage, before tremor emerged, they might be able to flag patients for early intervention, says Max Little, PhD, project director for the Parkinson’s Voice Initiative. “That is the ‘holy grail’ for finding an eventual cure.”

Again, the smartphone shows potential. In a 2022 Australian study, an AI-powered app was able to identify people with Parkinson’s based on brief voice recordings, although the sample size was small. On a larger scale, the Parkinson’s Voice Initiative collected some 17,000 samples from people across the world. “The aim was to remotely detect those with the condition using a telephone call,” says Dr. Little. It did so with about 65% accuracy. “While this is not accurate enough for clinical use, it shows the potential of the idea,” he says.

Dr. Rudzicz worked on the team behind Winterlight, an iPad app that analyzes 550 features of speech to detect dementia and Alzheimer’s (as well as mental illness). “We deployed it in long-term care facilities,” he says, identifying patients who need further review of their mental skills. Stroke is another area of interest, because slurred speech is a highly subjective measure, says Dr. Anderson. AI technology could provide a more objective evaluation.
 

Mood and psychiatric disorders (depression, schizophrenia, bipolar disorders)

No established biomarkers exist for diagnosing depression. Yet if you’re feeling down, there’s a good chance your friends can tell – even over the phone.

“We carry a lot of our mood in our voice,” says Dr. Powell. Bipolar disorder can also alter voice, making it louder and faster during manic periods, then slower and quieter during depressive bouts. The catatonic stage of schizophrenia often comes with “a very monotone, robotic voice,” says Dr. Anderson. “These are all something an algorithm can measure.”

Apps are already being used – often in research settings – to monitor voices during phone calls, analyzing rate, rhythm, volume, and pitch, to predict mood changes. For example, the PRIORI project at the University of Michigan is working on a smartphone app to identify mood changes in people with bipolar disorder, especially shifts that could increase suicide risk.

The content of speech may also offer clues. In a University of California, Los Angeles, study published in the journal PLoS One, people with mental illnesses answered computer-programmed questions (like “How have you been over the past few days?”) over the phone. An app analyzed their word choices, paying attention to how they changed over time. The researchers found that AI analysis of mood aligned well with doctors’ assessments and that some people in the study actually felt more comfortable talking to a computer.
 

Respiratory disorders (pneumonia, COPD)

Beyond talking, respiratory sounds like gasping or coughing may point to specific conditions. “Emphysema cough is different, COPD cough is different,” says Dr. Bensoussan. Researchers are trying to find out if COVID-19 has a distinct cough.

Breathing sounds can also serve as signposts. “There are different sounds when we can’t breathe,” says Dr. Bensoussan. One is called stridor, a high-pitched wheezing often resulting from a blocked airway. “I see tons of people [with stridor] misdiagnosed for years – they’ve been told they have asthma, but they don’t,” says Dr. Bensoussan. AI analysis of these sounds could help doctors more quickly identify respiratory disorders.
 

Pediatric voice and speech disorders (speech and language delays, autism)

Babies who later have autism cry differently as early as 6 months of age, which means an app like ChatterBaby could help flag children for early intervention, says Dr. Anderson. Autism is linked to several other diagnoses, such as epilepsy and sleep disorders. So analyzing an infant’s cry could prompt pediatricians to screen for a range of conditions.

ChatterBaby has been “incredibly accurate” in identifying when babies are in pain, says Dr. Anderson, because pain increases muscle tension, resulting in a louder, more energetic cry. The next goal: “We’re collecting voices from babies around the world,” she says, and then tracking those children for 7 years, looking to see if early vocal signs could predict developmental disorders. Vocal samples from young children could serve a similar purpose.
 

And that’s only the beginning

Eventually, AI technology may pick up disease-related voice changes that we can’t even hear. In a new Mayo Clinic study, certain vocal features detectable by AI – but not by the human ear – were linked to a three-fold increase in the likelihood of having plaque buildup in the arteries.

“Voice is a huge spectrum of vibrations,” explains study author Amir Lerman, MD. “We hear a very narrow range.” 

The researchers aren’t sure why heart disease alters voice, but the autonomic nervous system may play a role, because it regulates the voice box as well as blood pressure and heart rate. Dr. Lerman says other conditions, like diseases of the nerves and gut, may similarly alter the voice. Beyond patient screening, this discovery could help doctors adjust medication doses remotely, in line with these inaudible vocal signals.

“Hopefully, in the next few years, this is going to come to practice,” says Dr. Lerman.

Still, in the face of that hope, privacy concerns remain. Voice is an identifier that’s protected by the federal Health Insurance Portability and Accountability Act, which requires privacy of personal health information. That is a major reason why no large voice databases exist yet, says Dr. Bensoussan. (This makes collecting samples from children especially challenging.) Perhaps more concerning is the potential for diagnosing disease based on voice alone. “You could use that tool on anyone, including officials like the president,” says Dr. Rameau.

But the primary hurdle is the ethical sourcing of data to ensure a diversity of vocal samples. For the Voice as a Biomarker project, the researchers will establish voice quotas for different races and ethnicities, ensuring algorithms can accurately analyze a range of accents. Data from people with speech impediments will also be gathered.

Despite these challenges, researchers are optimistic. “Vocal analysis is going to be a great equalizer and improve health outcomes,” predicts Dr. Anderson. “I’m really happy that we are beginning to understand the strength of the voice.”

“Algorithms have a larger training base,” says Dr. Anderson, who developed an app called ChatterBaby that analyzes infant cries. “We have a million samples at our disposal to train our algorithms. I don’t know if I’ve heard a million different babies crying in my life.”

So which health conditions show the most promise for voice analysis? The Voice as a Biomarker project will focus on five categories.
 

Voice disorders (cancers of the larynx, vocal fold paralysis, benign lesions on the larynx)

Obviously, vocal changes are a hallmark of these conditions, which cause things like breathiness or “roughness,” a type of vocal irregularity. Hoarseness that lasts at least 2 weeks is often one of the earliest signs of laryngeal cancer. Yet it can take months – one study found 16 weeks was the average – for patients to see a doctor after noticing the changes. Even then, laryngologists still misdiagnosed some cases of cancer when relying on vocal cues alone.

Now imagine a different scenario: The patient speaks into a smartphone app. An algorithm compares the vocal sample with the voices of laryngeal cancer patients. The app spits out the estimated odds of laryngeal cancer, helping providers decide whether to offer the patient specialist care.

Or consider spasmodic dysphonia, a neurological voice disorder that triggers spasms in the muscles of the voice box, causing a strained or breathy voice. Doctors who lack experience with vocal disorders may miss the condition. This is why diagnosis takes an average of nearly 4.5 years, according to a study in the Journal of Voice, and may include everything from allergy testing to psychiatric evaluation, says Dr. Powell. Artificial intelligence technology trained to recognize the disorder could help eliminate such unnecessary testing.
 

Neurological and neurodegenerative disorders (Alzheimer’s, Parkinson’s, stroke, ALS) 

For Alzheimer’s and Parkinson’s, “one of the first changes that’s notable is voice,” usually appearing before a formal diagnosis, says Anais Rameau, MD, an assistant professor of laryngology at Weill Cornell Medicine, New York, and another member of the NIH project. Parkinson’s may soften the voice or make it sound monotone, while Alzheimer’s disease may change the content of speech, leading to an uptick in “umms” and a preference for pronouns over nouns.

With Parkinson’s, vocal changes can occur decades before movement is affected. If doctors could detect the disease at this stage, before tremor emerged, they might be able to flag patients for early intervention, says Max Little, PhD, project director for the Parkinson’s Voice Initiative. “That is the ‘holy grail’ for finding an eventual cure.”

Again, the smartphone shows potential. In a 2022 Australian study, an AI-powered app was able to identify people with Parkinson’s based on brief voice recordings, although the sample size was small. On a larger scale, the Parkinson’s Voice Initiative collected some 17,000 samples from people across the world. “The aim was to remotely detect those with the condition using a telephone call,” says Dr. Little. It did so with about 65% accuracy. “While this is not accurate enough for clinical use, it shows the potential of the idea,” he says.

Dr. Rudzicz worked on the team behind Winterlight, an iPad app that analyzes 550 features of speech to detect dementia and Alzheimer’s (as well as mental illness). “We deployed it in long-term care facilities,” he says, identifying patients who need further review of their mental skills. Stroke is another area of interest, because slurred speech is a highly subjective measure, says Dr. Anderson. AI technology could provide a more objective evaluation.
 

Mood and psychiatric disorders (depression, schizophrenia, bipolar disorders)

No established biomarkers exist for diagnosing depression. Yet if you’re feeling down, there’s a good chance your friends can tell – even over the phone.

“We carry a lot of our mood in our voice,” says Dr. Powell. Bipolar disorder can also alter voice, making it louder and faster during manic periods, then slower and quieter during depressive bouts. The catatonic stage of schizophrenia often comes with “a very monotone, robotic voice,” says Dr. Anderson. “These are all something an algorithm can measure.”

Apps are already being used – often in research settings – to monitor voices during phone calls, analyzing rate, rhythm, volume, and pitch, to predict mood changes. For example, the PRIORI project at the University of Michigan is working on a smartphone app to identify mood changes in people with bipolar disorder, especially shifts that could increase suicide risk.

The content of speech may also offer clues. In a University of California, Los Angeles, study published in the journal PLoS One, people with mental illnesses answered computer-programmed questions (like “How have you been over the past few days?”) over the phone. An app analyzed their word choices, paying attention to how they changed over time. The researchers found that AI analysis of mood aligned well with doctors’ assessments and that some people in the study actually felt more comfortable talking to a computer.
 

Respiratory disorders (pneumonia, COPD)

Beyond talking, respiratory sounds like gasping or coughing may point to specific conditions. “Emphysema cough is different, COPD cough is different,” says Dr. Bensoussan. Researchers are trying to find out if COVID-19 has a distinct cough.

Breathing sounds can also serve as signposts. “There are different sounds when we can’t breathe,” says Dr. Bensoussan. One is called stridor, a high-pitched wheezing often resulting from a blocked airway. “I see tons of people [with stridor] misdiagnosed for years – they’ve been told they have asthma, but they don’t,” says Dr. Bensoussan. AI analysis of these sounds could help doctors more quickly identify respiratory disorders.
 

Pediatric voice and speech disorders (speech and language delays, autism)

Babies who later have autism cry differently as early as 6 months of age, which means an app like ChatterBaby could help flag children for early intervention, says Dr. Anderson. Autism is linked to several other diagnoses, such as epilepsy and sleep disorders. So analyzing an infant’s cry could prompt pediatricians to screen for a range of conditions.

ChatterBaby has been “incredibly accurate” in identifying when babies are in pain, says Dr. Anderson, because pain increases muscle tension, resulting in a louder, more energetic cry. The next goal: “We’re collecting voices from babies around the world,” she says, and then tracking those children for 7 years, looking to see if early vocal signs could predict developmental disorders. Vocal samples from young children could serve a similar purpose.
 

And that’s only the beginning

Eventually, AI technology may pick up disease-related voice changes that we can’t even hear. In a new Mayo Clinic study, certain vocal features detectable by AI – but not by the human ear – were linked to a three-fold increase in the likelihood of having plaque buildup in the arteries.

“Voice is a huge spectrum of vibrations,” explains study author Amir Lerman, MD. “We hear a very narrow range.” 

The researchers aren’t sure why heart disease alters voice, but the autonomic nervous system may play a role, because it regulates the voice box as well as blood pressure and heart rate. Dr. Lerman says other conditions, like diseases of the nerves and gut, may similarly alter the voice. Beyond patient screening, this discovery could help doctors adjust medication doses remotely, in line with these inaudible vocal signals.

“Hopefully, in the next few years, this is going to come to practice,” says Dr. Lerman.

Still, in the face of that hope, privacy concerns remain. Voice is an identifier that’s protected by the federal Health Insurance Portability and Accountability Act, which requires privacy of personal health information. That is a major reason why no large voice databases exist yet, says Dr. Bensoussan. (This makes collecting samples from children especially challenging.) Perhaps more concerning is the potential for diagnosing disease based on voice alone. “You could use that tool on anyone, including officials like the president,” says Dr. Rameau.

But the primary hurdle is the ethical sourcing of data to ensure a diversity of vocal samples. For the Voice as a Biomarker project, the researchers will establish voice quotas for different races and ethnicities, ensuring algorithms can accurately analyze a range of accents. Data from people with speech impediments will also be gathered.

Despite these challenges, researchers are optimistic. “Vocal analysis is going to be a great equalizer and improve health outcomes,” predicts Dr. Anderson. “I’m really happy that we are beginning to understand the strength of the voice.”

Most of us have two voice changes in our lifetime: First during puberty, as the vocal cords thicken and the voice box migrates down the throat. Then a second time as aging causes structural changes that may weaken the voice.

But for some of us, there’s another voice shift, when a disease begins or when our mental health declines.

This is why more doctors are looking into voice as a biomarker – something that tells you that a disease is present.

Vital signs like blood pressure or heart rate “can give a general idea of how sick we are. But they’re not specific to certain diseases,” says Yael Bensoussan, MD, director of the University of South Florida, Tampa’s Health Voice Center and the coprincipal investigator for the National Institutes of Health’s Voice as a Biomarker of Health project.

“We’re learning that there are patterns” in voice changes that can indicate a range of conditions, including diseases of the nervous system and mental illnesses, she says.

Speaking is complicated, involving everything from the lungs and voice box to the mouth and brain. “A breakdown in any of those parts can affect the voice,” says Maria Powell, PhD, an assistant professor of otolaryngology (the study of diseases of the ear and throat) at Vanderbilt University, Nashville, Tenn., who is working on the NIH project.

You or those around you may not notice the changes. But researchers say voice analysis as a standard part of patient care – akin to blood pressure checks or cholesterol tests – could help identify those who need medical attention earlier.

Often, all it takes is a smartphone – “something that’s cheap, off-the-shelf, and that everyone can use,” says Ariana Anderson, PhD, director of the University of California, Los Angeles, Laboratory of Computational Neuropsychology.

“You can provide voice data in your pajamas, on your couch,” says Frank Rudzicz, PhD, a computer scientist for the NIH project. “It doesn’t require very complicated or expensive equipment, and it doesn’t require a lot of expertise to obtain.” Plus, multiple samples can be collected over time, giving a more accurate picture of health than a single snapshot from, say, a cognitive test.

Over the next 4 years, the Voice as a Biomarker team will receive nearly $18 million to gather a massive amount of voice data. The goal is 20,000-30,000 samples, along with health data about each person being studied. The result will be a sprawling database scientists can use to develop algorithms linking health conditions to the way we speak.

For the first 2 years, new data will be collected exclusively via universities and high-volume clinics to control quality and accuracy. Eventually, people will be invited to submit their own voice recordings, creating a crowdsourced dataset. “Google, Alexa, Amazon – they have access to tons of voice data,” says Dr. Bensoussan. “But it’s not usable in a clinical way, because they don’t have the health information.”

Dr. Bensoussan and her colleagues hope to fill that void with advance voice screening apps, which could prove especially valuable in remote communities that lack access to specialists or as a tool for telemedicine. Down the line, wearable devices with voice analysis could alert people with chronic conditions when they need to see a doctor.

“The watch says, ‘I’ve analyzed your breathing and coughing, and today, you’re really not doing well. You should go to the hospital,’ ” says Dr. Bensoussan, envisioning a wearable for patients with COPD. “It could tell people early that things are declining.”

Artificial intelligence may be better than a brain at pinpointing the right disease. For example, slurred speech could indicate Parkinson’s, a stroke, or ALS, among other things.

“We can hold approximately seven pieces of information in our head at one time,” says Dr. Rudzicz. “It’s really hard for us to get a holistic picture using dozens or hundreds of variables at once.” But a computer can consider a whole range of vocal markers at the same time, piecing them together for a more accurate assessment.

The exploration started in 2004 with a 62-year-old man who presented to an emergency department with acute shortness of breath, tachycardia with chest discomfort, and light-headedness, Amado Alejandro Baez, MD, said in a presentation at the 2022 scientific assembly of the American College of Emergency Physicians.

The patient arrived on day 20 after a radical cystoprostatectomy. He had driven 4 hours from another city for a urology follow-up visit. On arrival, he developed respiratory distress symptoms and presented to the emergency department, said Dr. Baez, professor of emergency medicine and epidemiology at the Medical College of Georgia/Augusta University and triple-board certified in EMS, emergency medicine, and critical care.

The patient developed a massive pulmonary embolism with acute cor pulmonale (right-sided heart failure). An electrocardiogram showed an S1Q3T3, demonstrating the distinctive nature of right ventricular failure, said Dr. Baez.

Research has demonstrated the differences in physiology between the right and left ventricles, he said.

Dr. Baez highlighted some of the features of right ventricle (RV) failure and how to manage it. Notably, the RV is thinner and less resilient. “RV failure patients may fall off the Starling curve,” in contrast to patients with isolated left ventricle (LV) failure.

RV pressure overload is associated with a range of conditions, such as pericardial disease, pulmonary embolism, acute respiratory distress syndrome, and pulmonary arterial hypertension. When combined with RV overload, patients may develop intracardiac shunting or coronary heart disease, Dr. Baez said. Decreased contractility associated with RV failure can result from sepsis, right ventricular myocardial infarction, myocarditis, and arrhythmia.

Dr. Baez cited the 2018 scientific statement from the American Heart Association on the evaluation and management of right-sided heart failure. The authors of the statement noted that the complicated geometry of the right heart makes functional assessment a challenge. They wrote that various hemodynamic and biochemical markers can help guide clinical assessment and therapeutic decision-making.

Increased RV afterload drives multiple factors that can ultimately lead to cardiogenic shock and death, said Dr. Baez. These factors include decreased RV oxygen delivery, decreased RV coronary perfusion, decreased systemic blood pressure, and low carbon monoxide levels. RV afterload also leads to decreased RV contractility, an increase in RV oxygen demand, and tension in the RV wall, and it may contribute to tricuspid valve insufficiency, neurohormonal activation, and RV ischemia.

Treatment strategies involve improving symptoms and stopping disease progression, said Baez. In its scientific statement, the AHA recommends steps for assessing RV and LV function so as to identify RV failure as soon as possible, he said. After excluding pericardial disease, the AHA advises diagnosis and treatment of etiology-specific causes, such as right ventricular MI, pulmonary embolism, and sepsis. For arrhythmias, it recommends maintaining sinus rhythm when possible and considering a pacemaker to maintain atrioventricular synchrony and to avoid excessive bradycardia.

In its statement, the AHA also recommends optimizing preload with right arterial pressure/central venous pressure of 8-12 mm Hg, said Dr. Baez. Preload optimization combined with afterload reduction and improved contractility are hallmarks of care for patients with RV failure.

Avoiding systemic hypotension can prevent sequelae, such as myocardial ischemia and further hypotension, he said.

Optimization of fluid status is another key to managing RV failure, said Dr. Baez. Right heart coronary perfusion pressure can be protected by maintaining mean arterial pressure, and consideration should be given to reducing the RV afterload. Other strategies include inotropic medications and rhythm stabilization.

In general, for RV failure patients, “correct hypoxia, hypercarbia, and acidosis and avoid intubation when possible,” he said. Extracorporeal membrane oxygenation (ECMO) may be an option, depending on how many mechanical ventilator settings need to be adjusted.

In a study by Dr. Baez and colleagues published in Critical Care Medicine, the authors presented a Bayesian probability model for plasma lactate and severity of illness in cases of acute pulmonary embolism. “This Bayesian model demonstrated that the combination of shock index and lactate yield superior diagnostic gains than those compare to the sPESI and lactate,” Dr. Baez said.

The care model needs to be specific to the etiology, he added. Volume management in congested pulmonary hypertension involves a “squeeze and diurese” strategy.

According to the Internet Book of Critical Care, for patients with mean arterial pressure (MAP) of 60 mm Hg, central venous pressure (CVP) of 25 mm Hg, renal perfusion pressure of 25 mm Hg, and no urine output, a vasopressor should be added to treatment, Dr. Baez said. In cases in which the MAP 75 mm Hg, the CVP is 25 mm Hg, the renal perfusion pressure is 50 mm Hg, and the patient has good urine output, vasopressors should be continued and fluid should be removed through use of a diuretic. For patients with a MAP of 75 mm Hg, a CVP of 12 mm Hg, and renal perfusion pressure of 63 mm Hg who have good urine output, the diuretic and the vasopressor should be discontinued.

Dr. Baez also reviewed several clinical studies of the utility of acute mechanical circulatory support systems for RV failure.

In two small studies involving a heart pump and a right ventricular assistive device, the 30-day survival rate was approximately 72%-73%. A study of 179 patients involving ECMO showed an in-hospital mortality rate of 38.6%, he said.

Overall, “prompt diagnosis, hemodynamic support, and initiation of specific treatment” are the foundations of managing RV failure, he concluded.

Dr. Baez disclosed no relevant financial relationships.

For arrhythmias, it recommends maintaining sinus rhythm when possible and considering a pacemaker to maintain atrioventricular synchrony and to avoid excessive bradycardia.

In its statement, the AHA also recommends optimizing preload with right arterial pressure/central venous pressure of 8-12 mm Hg, said Dr. Baez. Preload optimization combined with afterload reduction and improved contractility are hallmarks of care for patients with RV failure.

Avoiding systemic hypotension can prevent sequelae, such as myocardial ischemia and further hypotension, he said.

Optimization of fluid status is another key to managing RV failure, said Dr. Baez. Right heart coronary perfusion pressure can be protected by maintaining mean arterial pressure, and consideration should be given to reducing the RV afterload. Other strategies include inotropic medications and rhythm stabilization.

In general, for RV failure patients, “correct hypoxia, hypercarbia, and acidosis and avoid intubation when possible,” he said. Extracorporeal membrane oxygenation (ECMO) may be an option, depending on how many mechanical ventilator settings need to be adjusted.

In a study by Dr. Baez and colleagues published in Critical Care Medicine, the authors presented a Bayesian probability model for plasma lactate and severity of illness in cases of acute pulmonary embolism. “This Bayesian model demonstrated that the combination of shock index and lactate yield superior diagnostic gains than those compare to the sPESI and lactate,” Dr. Baez said.

The care model needs to be specific to the etiology, he added. Volume management in congested pulmonary hypertension involves a “squeeze and diurese” strategy.

According to the Internet Book of Critical Care, for patients with mean arterial pressure (MAP) of 60 mm Hg, central venous pressure (CVP) of 25 mm Hg, renal perfusion pressure of 25 mm Hg, and no urine output, a vasopressor should be added to treatment, Dr. Baez said. In cases in which the MAP 75 mm Hg, the CVP is 25 mm Hg, the renal perfusion pressure is 50 mm Hg, and the patient has good urine output, vasopressors should be continued and fluid should be removed through use of a diuretic. For patients with a MAP of 75 mm Hg, a CVP of 12 mm Hg, and renal perfusion pressure of 63 mm Hg who have good urine output, the diuretic and the vasopressor should be discontinued.

Dr. Baez also reviewed several clinical studies of the utility of acute mechanical circulatory support systems for RV failure.

In two small studies involving a heart pump and a right ventricular assistive device, the 30-day survival rate was approximately 72%-73%. A study of 179 patients involving ECMO showed an in-hospital mortality rate of 38.6%, he said.

Overall, “prompt diagnosis, hemodynamic support, and initiation of specific treatment” are the foundations of managing RV failure, he concluded.

Dr. Baez disclosed no relevant financial relationships.

These should be the best of times for geriatric medicine.

The baby boom has become a senior surge, bringing in a rapidly growing pool of aging patients for geriatricians to treat. According to the U.S. Census Bureau, more than 56 million adults aged 65 and older live in the United States. They account for about 17% of the nation’s population. That number is expected to hit 73 million by 2030 and 86 million by 2050.

The American Geriatrics Society estimates that 30% of older people require the attention of geriatricians. These clinicians excel in managing complex cases – patients with multiple comorbidities, such as coronary artery disease, dementia, and osteoporosis, who are taking a half dozen, and often more, medications.

But instead of thriving, geriatrics as a medical specialty appears to be hobbling. In the 2010s, geriatricians called for “25,000 [such specialists] by 2025.” As of 2021, 7123 certified geriatricians were practicing in the United States, according to the American Board of Medical Specialties.

The Health Resources and Services Administration, a federal agency that addresses medical workforce shortages, estimates that there will be 6,230 geriatricians by 2025, or approximately 1 for every 3,000 older adults requiring geriatric care. HRSA projects a shortage of 27,000 geriatricians by 2025.

The specialty has faced an uphill battle to attract fellows. This year, only 43% of the nation’s 177 geriatrics fellowship slots were filled, according to November’s National Resident Match Program report. Family medicine–based geriatrics achieved only a 32% fill rate, while internal medicine–based programs saw a rate of 45%.

“Our numbers are shrinking so we need another approach to make sure older adults get the care they need and deserve,” said G. Michael Harper, MD, president of the 6,000-member AGS.

But Dr. Harper, who practices at the University of California, San Francisco, and the San Francisco VA Medical Center, added a positive note: “We may be struggling to increase the number of board-certified geriatricians, but the field itself has made a lot of progress in terms of improving clinical care through advancements in science and in the ways we deliver care.”

Dr. Harper cited the Hospital Elder Life Program, a hospital model developed at the Harvard-affiliated Marcus Institute for Aging Research, which uses an interprofessional team and trained volunteers to prevent delirium and functional decline. HELP has been adopted by more than 200 hospitals worldwide and has been successful at returning older adults to their homes or previous living situations with maintained or improved ability to function, he said.

Mark Supiano, MD, professor and chief of geriatrics at the University of Utah, Salt Lake City, said the specialty has been in shortage mode since ABMS recognized it in 1988. He was in the initial cohort of fellowship-trained geriatricians, sitting for the first certifying exam in geriatrics offered that year.

“Back then, the demographic imperative of the aging of our society was on the horizon. We’re living it now. I knew enough to recognize it was coming and saw an opportunity,” Dr. Supiano said in an interview. “There was so much then that we didn’t know about how to understand aging or how to care for older adults that there really was such a knowledge gap.”

Dr. Supiano is an associate editor of Hazzard’s Geriatric Medicine and Gerontology (McGraw-Hill Education), which has more than doubled in pages and word count during his career.
 

Unfavorable finances

Katherine Thompson, MD, director of the geriatrics fellowship program at the University of Chicago and codirector of UChicago’s Successful Aging and Frailty Evaluation Clinic, said money is a major reason for the struggle. “I think probably the biggest driver is financial,” she said. “A lot of people are graduating medical school with really astronomical amounts of medical school loans.”

Geriatricians, like other doctors, carry a large debt – $200,000, on average, not counting undergraduate debt, according to the Association of American Medical Colleges.

But the typical geriatrician earns less than an internist or family medicine doctor who doesn’t undergo the additional year of training, Dr. Thompson said. “There’s not a lot of financial motivation to do this fellowship,” she said.

The jobs website Zippia reports that geriatricians earned roughly $165,000 per year on average in 2022. The average annual incomes in 2022 were $191,000 for pediatricians, $215,000 for family physicians, and $223,000 for internists, according to the site.

In other words, Dr. Harper said, “geriatrics is one of the few professions where you can actually do additional training and make less money.”

The reason for the pay issue is simple: Geriatricians treat patients covered by Medicare, whose reimbursement schedules lag behind those of commercial insurers. The Kaiser Family Foundation reported in 2020 that private insurance paid 143% of Medicare rates on average for physician services.

Dr. Harper said overall compensation for geriatricians has “not gained a lot of traction,” but they can earn comfortable livings.

Still, representation of the specialty on the American Medical Association’s Relative Value Scale Update Committee has led to approval by the Centers for Medicare & Medicaid Services of billing codes that pay geriatricians “for what they do. Examples include chronic care management, advance care planning, and dementia evaluation,” he said.

But the geriatrician gap goes beyond money.

Ageism, too, may play a role in residents not choosing geriatrics.

“Our culture is ageist. It definitely focuses on youth and looks at aging as being loss rather than just a change in what works well and what doesn’t work well,” said Mary Tinetti, MD, a geriatrician and researcher at Yale University, New Haven, Conn. “Ageism happens among physicians, just because they’re part of the broader society.”
 

Time for a new goal?

Dr. Tinetti said she’s optimistic that new ideas about geriatricians teaching other primary care clinicians about the tenets of geriatric medicine, which offer a wholistic approach to comorbidities, such as diabetes, atrial fibrillation, dementia, hypertension, hyperlipidemia, and polypharmacy problems faced by this population, especially those 85 and older.

She has called on her profession to abandon the goal of increasing the numbers of board-certified geriatricians – whom she refers to as big “G” geriatricians. She instead wants to develop a “small, elite workforce” that discovers and tests geriatrics principles through research, teaches these principles to all healthcare professions and to the public, and disseminates and implements the policies.

“We need a cadre of geriatricians who train all other clinicians in the care of older adults,” Dr. Tinetti said. “The goal is not more geriatricians but rather the preparation of all clinicians in the care of older adults.”

Dr. Thompson said geriatricians are teaching primary care specialists, nurses, social workers, and other health care providers the principles of age-friendly care. AGS has for the past 20 years led a program called the Geriatrics for Specialists Initiative to increase geriatrics knowledge and expertise of surgical and medical specialists.

Some specialties have taken the cue and have added geriatrics-related hyphens through additional training: geriatric-emergency, geriatric-general surgery, geriatric-hospitalists, and more.

HRSA runs programs to encourage physicians to train as geriatricians and geriatrics faculty, and it encourages the geriatrics interdisciplinary team approach.

Richard Olague, director of public affairs for HRSA, said his agency has invested over $160 million over the past 4 years in the education and training of geriatricians and other health care professionals who care for the elderly through its Geriatrics Workforce Enhancement Program and Geriatrics Academic Career Awards Program. In the academic year 2020-2021, the two programs trained 109 geriatricians; 456 other geriatric/gerontology providers and students; 44,450 other healthcare workforce professionals and students; and served 17,666 patients and 5,409 caregivers.

Dr. Harper, like his fellow geriatricians, tells young doctors that geriatrics is a fulfilling specialty.

“I get to care for the whole person and sometimes their families, too, and in the process form rich and meaningful relationships. And while I’m rarely in the position to cure, I always have the ability to care,” he said. “Sometimes that can mean being an advocate trying to make sure my patients receive the care they need, and other times it might mean protecting them from burdensome care that is unlikely to lead to any meaningful benefit. There is great reward in all of that.”

Dr. Supiano said geriatric patients are being helped by the Age-Friendly Health System initiative of the John A. Hartford Foundation and the Institute for Healthcare Improvement in partnership with the American Hospital Association and the Catholic Health Association of the United States. This is sort of a seal of approval for facilities committed to age-friendly care.

“When you go to your hospital, if they don’t have this age-friendly health system banner on the front door ... you either ask why that is not there, or you vote with your feet and go to another health system that is age friendly,” he said. “Geriatricians are eternal optimists.”

Automated alerts to aid clinical decision-making are designed with the best of intentions but can be easy to ignore or overlook. But a randomized trial testing such electronic alerts or “nudges” for promoting statin prescribing may have identified a few design features that help their success, researchers say.

In the trial’s primary finding, for example, reminders displayed to primary care physicians in the electronic health record worked best when the system also reached out to the patient.

Reminders sent only to the clinician also boosted statin prescribing, but not as well, and nudging only the patient didn’t work at all, compared to a nudge-free usual care approach. The patient-only nudges consisted of text messages explaining why a statin prescription may figure in their upcoming appointment.
 

Nudge trustworthiness

Importantly, the clinician nudges were more than simply reminders to consider a statin prescription, Mitesh S. Patel, MD, MBA, Ascension Health, St. Louis, told this news organization. They also displayed the patient’s atherosclerotic cardiovascular disease (ASCVD) 10-year risk score and explained why a statin may be appropriate. He thinks that information, often left out of such clinical decision support alerts, increases physician trust in them.

In another key feature, Dr. Patel said, the EHR nudges themselves were actionable – that is, they were functional in ways that streamlined the prescribing process. In particular, they include checkbox shortcuts to prescribing statins at appropriate patient-specific dosages, making the entire process “faster and easier,” said Dr. Patel, who is senior author on the study published in JAMA Cardiology with lead author Srinath Adusumalli, MD, University of Pennsylvania, Philadelphia.

The timing may matter as well, he observed. In previous iterations of the study’s EHR nudge system, the nudge would appear “when you open the chart,” he said. “Now, it’s when you go to the orders section, which is when you’re going to be in the mindset of ordering prescriptions and tests.”

Prescription rates were higher with the doctor-patient nudges than with the doctor-only approach, Dr. Patel speculates, largely because the decision process for initiating statins is shared. “The most effective intervention is going to recognize that and try to bring the two groups together.”
 

Two text messages

The trial, with 158 participating physicians in 28 primary care practices, randomly assigned 4,131 patients to three intervention groups and one control group. Nudges were sent only to the physician, only to the patient, or to both physician and patient; and there was a no-nudge usual-care group.

Patient nudges consisted of two text messages, one 4 days and another 15 minutes before the appointment, announcing that prescription of a statin “to reduce the chance of a heart attack” would be discussed with the physician, the report states.

Statins are grossly underprescribed nationally, it notes, and that was reflected in prescription rates seen during the study’s initial 12-month, no-intervention period of observation. Rates ranged from only 4.7% up to 6% of patients across the four assignment groups.

During the subsequent 6-month intervention period, however, the rates climbed in the doctor-only and doctor-plus-patient nudge groups compared with usual care, by 5.5 (P = .01) and 7.2 (P = .001) absolute percentage points, respectively.

The overall cohort’s mean age was 65.5. About half were male, 29% were Black, 66% were White, and 22.6% already had a cardiovascular disease diagnosis. The analysis was adjusted for calendar month and preintervention statin prescribing rates. Further adjustment for demographics, insurance type, household income, and comorbidities yielded results similar to the primary analysis, the report states.
 

The results in context

“Although the differences in the combined clinician and patient and clinician-only arms were small, this outcome needs to be interpreted in the context of the population in which the study was performed,” an editorial accompanying the published report states.

For example, “the majority of untreated patients were candidates for primary, not secondary, prevention, making this group of patients particularly challenging for seeing large effect sizes of interventions.”

Moreover, “There was a high baseline prescription rate of statins in the statin-eligible population (approximately 70%) and a high rate of already established patients,” write Faraz S. Ahmad, MD, and Stephen D. Persell, MD, of Northwestern University, Chicago.

Among the approximately 30% of patients who had not previously been prescribed statins, the true target of the nudge interventions, the published trial report states, about 98% were not seeing the physician for the first time.

So “this may not have been the first opportunity to discuss statins,” they write. “It is possible that many of these patients were resistant to statins in the past, which could have created a ceiling effect for prescribing rates.”

Automated alerts to aid clinical decision-making are designed with the best of intentions but can be easy to ignore or overlook. But a randomized trial testing such electronic alerts or “nudges” for promoting statin prescribing may have identified a few design features that help their success, researchers say.

In the trial’s primary finding, for example, reminders displayed to primary care physicians in the electronic health record worked best when the system also reached out to the patient.

Reminders sent only to the clinician also boosted statin prescribing, but not as well, and nudging only the patient didn’t work at all, compared to a nudge-free usual care approach. The patient-only nudges consisted of text messages explaining why a statin prescription may figure in their upcoming appointment.
 

Nudge trustworthiness

Importantly, the clinician nudges were more than simply reminders to consider a statin prescription, Mitesh S. Patel, MD, MBA, Ascension Health, St. Louis, told this news organization. They also displayed the patient’s atherosclerotic cardiovascular disease (ASCVD) 10-year risk score and explained why a statin may be appropriate. He thinks that information, often left out of such clinical decision support alerts, increases physician trust in them.

In another key feature, Dr. Patel said, the EHR nudges themselves were actionable – that is, they were functional in ways that streamlined the prescribing process. In particular, they include checkbox shortcuts to prescribing statins at appropriate patient-specific dosages, making the entire process “faster and easier,” said Dr. Patel, who is senior author on the study published in JAMA Cardiology with lead author Srinath Adusumalli, MD, University of Pennsylvania, Philadelphia.

The timing may matter as well, he observed. In previous iterations of the study’s EHR nudge system, the nudge would appear “when you open the chart,” he said. “Now, it’s when you go to the orders section, which is when you’re going to be in the mindset of ordering prescriptions and tests.”

Prescription rates were higher with the doctor-patient nudges than with the doctor-only approach, Dr. Patel speculates, largely because the decision process for initiating statins is shared. “The most effective intervention is going to recognize that and try to bring the two groups together.”
 

Two text messages

The trial, with 158 participating physicians in 28 primary care practices, randomly assigned 4,131 patients to three intervention groups and one control group. Nudges were sent only to the physician, only to the patient, or to both physician and patient; and there was a no-nudge usual-care group.

Patient nudges consisted of two text messages, one 4 days and another 15 minutes before the appointment, announcing that prescription of a statin “to reduce the chance of a heart attack” would be discussed with the physician, the report states.

A new meta-analysis of 884 studies evaluating 27 different types of antioxidant supplements has suggested that some of these micronutrients – including omega-3 fatty acids, folic acid, and coenzyme Q10 – may produce significant cardiovascular benefits.

Other antioxidant supplements that showed some evidence of reducing cardiovascular risk were omega-6 fatty acids, L-arginine, L-citrulline, magnesium, zinc, alpha-lipoic acid, melatonin, catechin, curcumin, flavanol, genistein, and quercetin.

No effect was seen with vitamin C, vitamin D, vitamin E, or selenium, and beta-carotene supplementation was linked to an increase in all-cause mortality in the analysis.

The study is published in the Journal of the American College of Cardiology and was also published online.

“Our systematic assessment and quantification of multiple differential effects of a wide variety of micronutrients and phytochemicals on cardiometabolic health indicate that an optimal nutritional strategy to promote cardiometabolic health will likely involve personalized combinations of these nutrients,” the authors, led by Peng An, PhD, China Agricultural University, Beijing, conclude.

“Identifying the optimal mixture of micronutrients is important, as not all are beneficial, and some may even have harmful effects,” senior author Simin Liu, MD, professor of epidemiology and medicine at Brown University, Providence, R.I., said in an American College of Cardiology press release.

“The micronutrients identified require further validation in large, high-quality interventional trials to establish clinical efficacy to determine their long-term balance of risks and benefits,” the authors add.
 

Experts cautious

Experts in the field of cardiovascular risk and preventative medicine have urged caution in interpreting these results.

JoAnn Manson, MD, chief of the division of preventive medicine at Brigham and Women’s Hospital, Boston, told this news organization that she has concerns that some of the results in the meta-analysis may be inflated by publication bias and some are chance findings that haven’t been well replicated.

“Although this meta-analysis of micronutrients and cardiometabolic health was based on randomized clinical trials, the quality of randomized trials on this subject varies widely,” she noted.

“The study is informative, but the conclusions are only as good as the quality of the evidence. Some of the trials are limited by short duration, and included trials have a wide range of quality, dosing, inclusion criteria, imperfect blinding, and few of them focus on hard clinical events,” Dr. Manson said. “Also, with trials of this nature, the potential for publication bias warrants consideration, because many of the smaller trials with unfavorable or neutral results may remain unpublished or not even be submitted for publication.”   

However, she added, “despite these limitations, this is an important contribution to the literature on micronutrients and health – and goes a long way in separating the wheat from the chaff.”

Steve Nissen, MD, chief academic officer of the Heart Vascular and Thoracic Institute at the Cleveland Clinic, was more critical of the meta-analysis.

“This study does not make sense. Some of the ‘micronutrients’ in this meta-analysis have undergone thorough testing in large randomized clinical trials that showed different results. I am skeptical whether any of the purported benefits of these supplements would be confirmed in a high-quality randomized controlled trial,” he said.

Dr. Nissen added that many of the included studies are low in quality. “I must quote [renowned cardiologist, Dr.] Franz Messerli: ‘A meta-analysis is like making bouillabaisse. ... One rotten fish can spoil the broth.’ This type of analysis does not override high-quality large, randomized trials.”

In the JACC paper, the study investigators note that the American Heart Association now recommends dietary patterns, including the Mediterranean diet and DASH (the Dietary Approach to Stop Hypertension), as preventive or treatment approaches for cardiovascular disease. A common feature of these dietary patterns is that they are low in saturated fat and sodium and rich in micronutrients such as phytochemicals, unsaturated fatty acids, antioxidant vitamins, and minerals.

“To personalize cardiometabolic preventive and therapeutic dietary practices, it is of critical importance to have a comprehensive and in-depth understanding of the balance of benefits and risks associated with constituent micronutrients in diverse dietary patterns,” they note.

They therefore conducted the current systematic review and meta-analyses of all available randomized controlled trials investigating the effect of micronutrients with antioxidant properties on cardiovascular risk factors and events in diverse populations.

The meta-analysis included a total of 884 randomized trials evaluating 27 types of micronutrients among 883,627 participants.

Results showed that supplementation with n-3 fatty acids, n-6 fatty acids, L-arginine, L-citrulline, folic acid, magnesium, zinc, alpha-lipoic acid, coenzyme Q10, melatonin, catechin, curcumin, flavanol, genistein, and quercetin had “moderate-to high-quality evidence” for reducing cardiovascular risk factors.

Specifically, n-3 fatty acid supplementation was linked to reduced rates of cardiovascular mortality (relative risk, 0.93), myocardial infarction (RR, 0.85), and coronary heart disease events (RR, 0.86). Folic acid supplementation was linked to a decreased stroke risk (RR, 0.84) and coenzyme Q10 was associated with a lower rate of all-cause mortality (RR, 0.68).

“The current study represents the first attempt in providing a comprehensive and most up-to-date evidence map that systematically assessed the quality and quantity of all randomized trials linking the effects of a wide variety of micronutrients on cardiovascular risk factors,” the authors say.

“The comprehensive evidence map presented here highlights the importance of micronutrient diversity and the balance of benefits and risks in the design of whole food–based dietary patterns to promote cardiometabolic health, which may require cultural adaptations to apply globally,” they conclude.

Commenting on some of the specific beneficial findings, Dr. Manson said: “I do believe that the marine omega-3s confer heart benefits, but results are not consistent and vary by dose and formulation.”

However, she pointed out that, regarding folic acid, a previous meta-analysis including eight large randomized trials in more than 37,000 participants found no reduction in coronary events, stroke, or major cardiovascular events with folic acid supplementation, compared with placebo, “so the reported stroke benefit would need further confirmation.”

In an accompanying editorial, Juan Gormaz, PhD, University of Chile, and Rodrigo Carrasco, MD, Chilean Society of Cardiology and Cardiovascular Surgery, both in Santiago, state: “Given that the compounds with more pleiotropic properties produced the better outcomes, the antioxidant paradigm on cardiovascular prevention can be challenged. For example, inasmuch as n-3 fatty acids have antiplatelet and anti-inflammatory properties, they are too complex to enable attribution of the observed benefits solely to their antioxidant capacity.”

The editorialists note that from a research point of view, “although the current information opens interesting perspectives for future consolidation of some antioxidants in preventive cardiology, there is still a long way to go in terms of generating evidence.”

They add that the challenge now for some compounds is to begin establishing consensus in definitions of dose and combinations, as well as continue strengthening the evidence of effectiveness.

“Regarding routine clinical practice, these results begin to open spaces for the integration of new tools into the therapeutic arsenal aimed at cardiovascular prevention in selected populations, which could be easily accessible and, with specific exceptions, would present a low frequency of adverse effects,” they conclude.

However, she pointed out that, regarding folic acid, a previous meta-analysis including eight large randomized trials in more than 37,000 participants found no reduction in coronary events, stroke, or major cardiovascular events with folic acid supplementation, compared with placebo, “so the reported stroke benefit would need further confirmation.”

In an accompanying editorial, Juan Gormaz, PhD, University of Chile, and Rodrigo Carrasco, MD, Chilean Society of Cardiology and Cardiovascular Surgery, both in Santiago, state: “Given that the compounds with more pleiotropic properties produced the better outcomes, the antioxidant paradigm on cardiovascular prevention can be challenged. For example, inasmuch as n-3 fatty acids have antiplatelet and anti-inflammatory properties, they are too complex to enable attribution of the observed benefits solely to their antioxidant capacity.”

The editorialists note that from a research point of view, “although the current information opens interesting perspectives for future consolidation of some antioxidants in preventive cardiology, there is still a long way to go in terms of generating evidence.”

They add that the challenge now for some compounds is to begin establishing consensus in definitions of dose and combinations, as well as continue strengthening the evidence of effectiveness.

“Regarding routine clinical practice, these results begin to open spaces for the integration of new tools into the therapeutic arsenal aimed at cardiovascular prevention in selected populations, which could be easily accessible and, with specific exceptions, would present a low frequency of adverse effects,” they conclude.

Heart failure associated with illicit use of the psychostimulant methamphetamine (methHF) is increasing in the United States and around the world across racial, ethnic, and socioeconomic groups, a literature review indicates.

MethHF is associated with increased severity for HF, longer inpatient stay, and more readmissions, compared with non-MethHF, the data show.

Clinicians “need to consider methamphetamine as a potential etiology for heart failure and include a substance use history when evaluating patients. Treating methamphetamine use disorder improves heart failure outcomes,” first author Veena Manja, MD, PhD, with Stanford (Calif.) University, said in an interview.

The study was published online in the journal Heart.
 

Poor outcomes, ‘staggering’ costs

This “thoughtful” review is “important and necessary,” Jonathan Davis, MD, director of the heart failure program, Zuckerberg San Francisco General Hospital, wrote in an editorial in the journal.

Dr. Davis noted that patients with Meth HF are at increased risk for poor outcomes and death and the health care costs related to MethHF are “staggering.”

As an example, inpatient data for California show annual charges related to MethHF rose by 840% from 2008 to 2018, from $41.5 million to $390.2 million, compared with 82% for all HF, which rose from $3.5 billion to $6.8 billion.

Illicit use of methamphetamine – also known as “crystal meth,” “ice,” and “speed” – has been linked to hypertension, MI, stroke, aortic dissection, and sudden death. But until now, there was no comprehensive systematic review of published studies on MethHF.

“Our goal was to compile current knowledge on the topic, increase awareness of this condition and identify areas for future research,” Dr. Manja said.

The researchers reviewed 21 observational studies, mostly from the United States (14 from California), between 1997 and 2020. The mean age of adults with MethHF ranged in age from 35 to 60 and more than half were male (57%).

Illicit methamphetamine was inhaled, injected, swallowed, smoked, and snorted. The reported frequency ranged from daily to every other week, and the total monthly dose ranged from 0.35 g to 24.5 g.

The average duration of meth use before HF diagnosis was 5 years. However, 18% of users developed HF within 1 year of starting to use illicit methamphetamine. In some cases, HF was diagnosed after a single use.

The researchers also note that MethHF with preserved left ventricular ejection fraction, seen in up to 44% of cases, is a distinct entity that may progress to reduced LVEF with continued use.

MethHF is also associated with a greater likelihood of other substance abuse, PTSD, depression, and other heart and kidney disease.

Factors associated with improved MethHF outcomes include female sex, meth abstinence, and adherence to guideline-directed HF therapy.

Improvement in MethHF outcomes is possible even if abstinence is not consistent, a finding that lends support to harm reduction principles of “meeting patients where they are instead of insisting on complete abstinence,” the researchers said.
 

Large gaps in knowledge

They were unable to combine the results into a meta-analysis because of heterogeneity in study design, population, comparator, and outcome assessment. Also, the overall risk of bias is moderate because of the presence of confounders, selection bias and poor matching, and the overall certainty in the evidence is very low,.

No study evaluated the incidence or prevalence of HF among methamphetamine users and inconsistent history taking and testing in patients with HF impeded accurate MethHF prevalence assessment.

Several studies, however, document an increasing incidence of MethHF, particularly over the past decade.

One study from California reported a 585% increase in MethHF hospital admissions between 2008 and 2018. An analysis of the National Inpatient Survey found a 12-fold increase in annual MethHF hospitalizations between 2002 and 2014.

“The results of this systematic review highlight large gaps in our knowledge” of MethHF, Dr. Manja said in an interview.

“We need to understand the epidemiology, prevalence, factors that confer susceptibility to cardiovascular outcomes, and need research into treatment targeted toward this disease,” Dr. Manja added. “We should consider options to integrate substance use treatment in HF/cardiology/primary care clinics and design a multidisciplinary patient-centered approach.”

Dr. Davis agreed. This work “highlights that the standard of care academically and clinically must be a broad team across the care spectrum to simultaneously address methamphetamine use, heart failure, and social determinants of health.”

This research had no specific funding. Dr. Manja and Dr. Davis reported no relevant disclosures.

Adding a clinical decision support system (CDSS) to team-based diabetes care only modestly improved patients’ cardiovascular risk factors over team-based care alone, a randomized trial in China showed.

The tool required clinicians to enter patient data into a computer in order to generate individualized treatment recommendations, adding to their administrative burdens. It also couldn’t tackle patients’ problems with access and affordability of medications.

Nevertheless, the model could curtail physician burnout and improve the quality of care in primary care clinics with limited resources, the researchers said in a paper published in the Annals of Internal Medicine.

They concluded that the findings support “widespread adoption” of the model in China and other low- or middle-income countries where diabetes is on the rise.

Co–principal investigator Jiang He, MD, PhD, chair of epidemiology at Tulane University, New Orleans, said the findings could apply to federally qualified health care (FQHC) clinics that treat underserved patients in the United States.

“At many FQHC clinics, nurse practitioners have to take care of patients with multiple chronic disease conditions. Team-based care with a computerized clinical decision support system will help them and improve patient care,” Dr. He said.
 

Small improvements

To conduct the trial, called Diabetes Complication Control in Community Clinics (D4C), Dr. He and colleagues randomly assigned 19 out of the 38 community health centers in Xiamen, China, to have a clinical decision support tool installed on the computers of primary care physicians and health coaches.

Starting in October 2016 the researchers recruited 11,132 patients aged 50 and older with uncontrolled diabetes and at least one comorbid condition, with 5,475 patients receiving team-based care with the CDSS and the remainder receiving team-based care alone.

The CDSS generated individualized risk factor summaries and treatment recommendations, including prescriptions based on Chinese and U.S. clinical guidelines. It incorporated data on patients’ insurance plans and local availability of drugs.

At all centers, primary care physicians received training in managing glycemia, blood pressure, and lipids. Nurses were certified as health coaches after receiving training on nutrition, lifestyle changes, and medication adherence. Patients met with their coaches for half an hour every 3 months, and diabetes specialists visited each clinic monthly for team meetings and consultations.

After 18 months, patients undergoing team-based care alone lowered their hemoglobin A1c by 0.6 percentage points (95% confidence interval, –0.7 to –0.5 percentage points), LDL cholesterol by 12.5 mg/dL (95% CI, –13.6 to –11.3 mg/dL), and systolic blood pressure by 7.5 mm Hg (95% CI, –8.4 to –6.6 mm Hg).

The group whose care teams used the CDSS further reduced A1c by 0.2 percentage points (95% CI, –0.3 to –0.1 percentage points), LDL cholesterol by 6.5 mg/dL (95% CI, –8.3 to -4.6 mg/dL), and blood pressure by 1.5 mm Hg (95% CI, –2.8 to –0.3 mm Hg).

All-cause mortality did not differ between the groups. Serious adverse events occurred in 9.1% of the CDSS group, compared with 10.9% of the group whose care team did not use the CDSS.
 

Addressing social needs

Experts who were not involved in the trial said the marginal impact of the CDSS was no surprise given the mixed results of such tools in previous studies.

However, the lackluster result “might be a shock to people investing a lot in clinical decision support,” said Elbert Huang, MD, MPH, director of the Center for Chronic Disease Research and Policy at the University of Chicago.

Anne Peters, MD, a professor of medicine at the University of Southern California, Los Angeles, said the administrative burden of entering each patient’s data into the system would slow down care and frustrate clinicians. “The system has to be smarter than this.”

On the other hand, the findings of the D4C trial align with other research showing that team-based care strategies are effective for diabetes management.

Dr. Huang noted that there is a “well-established history” of diabetes quality improvement programs, health coaches, buddy programs, and community health worker programs. He added that the new findings “might help to remind everyone of the importance of these programs, which are not always well supported.”

“The bottom line of the paper might be that investing in patient engagement programs might get us 90% of the way to our goal of improving diabetes care,” Dr. Huang said.

Still, Dr. Peters said the portion of patients in the trial who benefited from team-based care seemed “disturbingly low.” Just 16.9% of patients who received team-based care and CDSS and 13% of those who received team-based care alone improved in all three measures. “This system doesn’t get you to where you want to be by a long shot.”

She added that a team-based approach, particularly the use of health coaches, would be a “huge improvement” over fragmented care provided in much of the U.S. safety-net system.
 

Another team approach

Many systems are striving to improve diabetes management in response to payment incentives, Dr. Huang said.

In a separate retrospective analysis, published in Annals of Family Medicine, researchers at the Mayo Clinic, Rochester, Minn., reported quality improvement gains among primary care practices that adopted a team-based model called Enhanced Primary Care Diabetes (EPCD). The model deployed a range of strategies, such as empowering nurses to engage with patients outside of scheduled office visits and including pharmacists on care teams.

Mayo’s approach did not specifically target underserved populations. Rather, researchers evaluated the model’s impact on about 17,000 patients treated at 32 Mayo internal medicine and family medicine practices of varying sizes, resources, and community settings.

Among staff clinician practices using the EPCD model improved patients’ scores on a composite quality measure called D5, which incorporates glycemic control, blood pressure control, low-density lipoprotein control, tobacco abstinence, and aspirin use.

Following implementation, the portion of patients in those practices meeting the D5 indicator increased from 42.9% to 45.0% (incident rate ratio, 1.005; P = .001).

Meanwhile, the portion of patients meeting the indicator increased from 38.9% to 42.0% (IRR, 1.011; P = .003) at resident physician practices that used the EPCD model and decreased from 36.2% to 35.5% (IRR, 0.994; P < .001) at staff clinician practices that did not use the model.

In contrast to the team-based approach used in China, the EPCD protocol “is very complex, and it will be difficult to implement in low-resource settings,” Dr. He said.

The D4C trial was funded by the Xiamen Municipal Health Commission. The Mayo study was funded by a National Institutes of Diabetes and Digestive and Kidney Diseases grant. Dr. He, Dr. Peters, and Dr. Huang reported no relevant financial interests.

Adding a clinical decision support system (CDSS) to team-based diabetes care only modestly improved patients’ cardiovascular risk factors over team-based care alone, a randomized trial in China showed.

She added that a team-based approach, particularly the use of health coaches, would be a “huge improvement” over fragmented care provided in much of the U.S. safety-net system.
 

Another team approach

Many systems are striving to improve diabetes management in response to payment incentives, Dr. Huang said.

In a separate retrospective analysis, published in Annals of Family Medicine, researchers at the Mayo Clinic, Rochester, Minn., reported quality improvement gains among primary care practices that adopted a team-based model called Enhanced Primary Care Diabetes (EPCD). The model deployed a range of strategies, such as empowering nurses to engage with patients outside of scheduled office visits and including pharmacists on care teams.

Mayo’s approach did not specifically target underserved populations. Rather, researchers evaluated the model’s impact on about 17,000 patients treated at 32 Mayo internal medicine and family medicine practices of varying sizes, resources, and community settings.

Among staff clinician practices using the EPCD model improved patients’ scores on a composite quality measure called D5, which incorporates glycemic control, blood pressure control, low-density lipoprotein control, tobacco abstinence, and aspirin use.

Following implementation, the portion of patients in those practices meeting the D5 indicator increased from 42.9% to 45.0% (incident rate ratio, 1.005; P = .001).

Meanwhile, the portion of patients meeting the indicator increased from 38.9% to 42.0% (IRR, 1.011; P = .003) at resident physician practices that used the EPCD model and decreased from 36.2% to 35.5% (IRR, 0.994; P < .001) at staff clinician practices that did not use the model.

In contrast to the team-based approach used in China, the EPCD protocol “is very complex, and it will be difficult to implement in low-resource settings,” Dr. He said.

The D4C trial was funded by the Xiamen Municipal Health Commission. The Mayo study was funded by a National Institutes of Diabetes and Digestive and Kidney Diseases grant. Dr. He, Dr. Peters, and Dr. Huang reported no relevant financial interests.
