A deep learning (DL) computer model improved upon the accuracy of cervical cancer diagnoses compared to traditional radiology. This could allow some women to avoid surgery and be treated with chemotherapy instead, suggested researchers.

The model mined tumor information from pelvic sagittal contrast-enhanced T1-weighted MRIs and combined this with clinical MRI lymph node status.

It was 90.62% sensitive and 87.16% specific for predicting lymph node metastases (LNMs) in a validation cohort of women who underwent surgery for cervical cancer.

The area under the curve was 0.933. The approach was significantly associated with disease-free survival (hazard ratio, 4.59; 95% confidence interval, 2.04-10.31; P < .001).

The study was published online on July 24 in JAMA Network Open.

“The findings of this study suggest that deep learning can be used as a preoperative noninvasive tool to diagnose lymph node metastasis in cervical cancer ... This model might be used preoperatively to help gynecologists make decisions,” said investigators led by Qingxia Wu, PhD, of the Northeastern University College of Medicine and Biomedical Information Engineering in Shenyang, China.

“Studies like these suggest that deep learning has the potential to improve the way we care for our patients,” but there’s much to be done “before these types of algorithms will be commonplace,” commented Christiaan Rees, MD, PhD, an internal medicine resident at Brigham and Women’s Hospital, Boston, who has a doctorate in quantitative biomedical sciences.

Next steps include repeated validation across multiple control groups, he said in an interview, as well as “finding ways to effectively integrate these tools into the radiologist’s day-to-day practice. One possibility would be for direct integration of the algorithm into the electronic health record.”
 

Accurate prediction could lead to skipping surgery

Chemotherapy, rather than surgery, is an option for women with positive lymph nodes (LNs), so accurate prediction can help them avoid an operation and its risks, the authors said.

The problem is that “the traditional methods for assessing LN status in cervical cancer, which rely mainly on assessing the size of LNs on MRI, have limited sensitivity in diagnosing LNM in cervical cancer and might lead to inappropriate treatment decisions,” they wrote.

“Although sentinel LN dissection ... shows good sensitivity and specificity, its application is limited by available facilities and experts,” the team said.

DL is an advanced form of artificial intelligence in which a computer program continuously improves on a given task as it incorporates more data – in Dr. Wu’s study, more than 14 million images. Deep learning has recently shown promise in several imaging tasks, such as diagnosing Alzheimer’s disease and screening for breast cancer.

Once adapted for cervical cancer, DL “does not require precise tumor delineation, making it an easy-to-use method in clinical practice. In many tumor analysis tasks, DL outperforms traditional radiomic features,” the team noted.

The study involved 479 women – 338 during model development, and 141 in the validation cohorts. The mean age of the participants was 49.1 years. They had undergone radical hysterectomy with pelvic lymphadenectomy for stage IB-IIB cervical cancer within 2 weeks of a pelvic MRI. Pathology reports were used to check the accuracy of the model’s predictions.

Specificity, sensitivity, and area under the curve were a little better in the study’s development cohort than its validation group, for whom median disease-free survival was 23 months versus 31 months among the patients in the development cohort. Nodes were positive on lymphadenectomy in a little more than 20% of women in both groups.

Incorporation of both intratumoral and peritumoral regions on contrast-enhanced T1-weighted MRIs versus axial T2-weighted and axial diffusion-weighted imaging, produced the highest sensitivity. Adding MRI-LN status – defined as positive when the short-axis diameter of the largest LN on MRI was ≥1 cm – improved the model’s specificity.

To understand how the model reached its conclusions, the team analyzed how it extracted features from tumor images. “In the shallow convolution layers, the DL model extracted simple tumor edge features ... while in deeper convolution layers, it extracted complex tumor texture information ... In the last convolution layer, the DL model extracted high-level abstract features (the fourteenth layer). Although these high-level features were so intricate that they were hard to interpret by general gross observation, they were associated with LN status,” the investigators said.

The team notes that “both intratumoral and peritumoral regions were necessary for the DL model to make decisions,” which “can probably be explained by the fact that higher lymphatic vessel density in peritumoral regions might lead to higher regional LNM.”

Commenting on the study, Dr. Rees said that “the authors did a [good] job of essentially deconstructing their neural network to see what the algorithm was actually picking up on to make its decision.

“One of the nice features of deep learning is that once the algorithm has been developed and validated, the end user doesn’t need any experience in deep learning in order to use it,” he added.

Even so, “while these resources can be incredibly powerful tools, they should not function in a vacuum without human judgment,” Dr. Rees said.

The work was funded by the National Natural Science Foundation of China, among others. The investigators have disclosed no relevant financial relationships.

If people try telemedicine, they’ll like telemedicine. And if they want to avoid a doctor’s office, as most people do these days, they’ll try telemedicine. That is the message coming from 1,000 people surveyed for DocASAP, a provider of online patient access and engagement systems.

Here are a couple of numbers: 92% of those who made a telemedicine visit said they were satisfied with the overall appointment experience, and 91% said that they are more likely to schedule a telemedicine visit instead of an in-person appointment. All of the survey respondents had visited a health care provider in the past year, and 40% already had made a telemedicine visit, DocASAP reported.

“Telehealth has quickly emerged as the preferred care setting during the pandemic and will drive patient behavior in the future,” Puneet Maheshwari, DocASAP cofounder and CEO, said in a statement. “As providers continue to adopt innovative technology to power a more seamless, end-to-end digital consumer experience, I expect telehealth to become fully integrated into overall care management.”

For now, though, COVID-19 is an overriding concern and health care facilities are suspect. When respondents were asked to identify the types of public facilities where they felt safe, hospitals were named by 32%, doctors’ offices by 26%, and ED/urgent care by just 12%, the DocASAP report said. Even public transportation got 13%.

The safest place to be, according to 42% of the respondents? The grocery store.

Of those surveyed, 43% “indicated they will not feel safe entering any health care setting until at least the fall,” the company said. An even higher share of patients, 68%, canceled or postponed an in-person appointment during the pandemic.

“No longer are remote health services viewed as ‘nice to have’ – they are now a must-have care delivery option,” DocASAP said in their report.

Safety concerns involving COVID-19, named by 47% of the sample, were the leading factor that would influence patients’ decision to schedule a telemedicine visit. Insurance coverage was next at 43%, followed by “ease of accessing quality care” at 40%, the report said.

Among those who had made a telemedicine visit, scheduling the appointment was the most satisfying aspect of the experience, according to 54% of respondents, with day-of-appointment wait time next at 38% and quality of the video/audio technology tied with preappointment communication at almost 33%, the survey data show.

Conversely, scheduling the appointment also was declared the most frustrating aspect of the telemedicine experience, although the total in that category was a much lower 29%.

“The pandemic has thrust profound change on every aspect of life, particularly health care. … Innovations – like digital and telehealth solutions – designed to meet patient needs will likely become embedded into the health care delivery system,” DocASAP said.

The survey was commissioned by DocASAP and conducted by marketing research company OnePoll on June 29-30, 2020.

A new analysis from Michigan’s largest health system provides sobering verification of the risks for QT interval prolongation in COVID-19 patients treated with hydroxychloroquine and azithromycin (HCQ/AZM).

One in five patients (21%) had a corrected QT (QTc) interval of at least 500 msec, a value that increases the risk for torsade de pointes in the general population and at which cardiovascular leaders have suggested withholding HCQ/AZM in COVID-19 patients.

“One of the most striking findings was when we looked at the other drugs being administered to these patients; 61% were being administered drugs that had QT-prolonging effects concomitantly with the HCQ and AZM therapy. So they were inadvertently doubling down on the QT-prolonging effects of these drugs,” senior author David E. Haines, MD, director of the Heart Rhythm Center at William Beaumont Hospital, Royal Oak, Mich., said in an interview.

A total of 34 medications overlapped with HCQ/AZM therapy are known or suspected to increase the risk for torsade de pointes, a potentially life-threatening ventricular tachycardia. The most common of these were propofol coadministered in 123 patients, ondansetron in 114, dexmedetomidine in 54, haloperidol in 44, amiodarone in 43, and tramadol in 26.

“This speaks to the medical complexity of this patient population, but also suggests inadequate awareness of the QT-prolonging effects of many common medications,” the researchers say.

The study was published Aug. 5 in JACC Clinical Electrophysiology.

Both hydroxychloroquine and azithromycin increase the risk for QTc-interval prolongation by blocking the KCHN2-encoded hERG potassium channel. Several reports have linked the drugs to a triggering of QT prolongation in patients with COVID-19.

For the present study, Dr. Haines and colleagues examined data from 586 consecutive patients admitted with COVID-19 to the Beaumont Hospitals in Royal Oak and Troy, Mich., between March 13 and April 6. A baseline QTc interval was measured with 12-lead ECG prior to treatment initiation with hydroxychloroquine 400 mg twice daily for two doses, then 200 mg twice daily for 4 days, and azithromycin 500 mg once followed by 250 mg daily for 4 days.

Because of limited availability at the time, lead II ECG telemetry monitoring over the 5-day course of HCQ/AZM was recommended only in patients with baseline QTc intervals of at least 440 msec.

Patients without an interpretable baseline ECG or available telemetry/ECG monitoring for at least 1 day were also excluded, leaving 415 patients (mean age, 64 years; 45% female) in the study population. More than half (52%) were Black, 52% had hypertension, 30% had diabetes, and 14% had cancer.

As seen in previous studies, the QTc interval increased progressively and significantly after the administration of HCQ/AZM, from 443 msec to 473 msec.

The average time to maximum QTc was 2.9 days in a subset of 135 patients with QTc measurements prior to starting therapy and on days 1 through 5.

In multivariate analysis, independent predictors of a potentially hazardous QTc interval of at least 500 msec were:

• Age older than 65 years (odds ratio, 3.0; 95% confidence interval, 1.62-5.54).
• History of  (OR, 4.65; 95% CI, 2.01-10.74).
• Admission  of at least 1.5 mg/dL (OR, 2.22; 95% CI, 1.28-3.84).
• Peak troponin I level above 0.04 mg/mL (OR, 3.89; 95% CI, 2.22-6.83).
• Body mass index below 30 kg/m² (OR for a BMI of 30 kg/m² or higher, 0.45; 95% CI, 0.26-0.78).

Concomitant use of drugs with known risk for torsade de pointes was a significant risk factor in univariate analysis (OR, 1.73; P = .036), but fell out in the multivariate model.

No patients experienced high-grade arrhythmias during the study. In all, 112 of the 586 patients died during hospitalization, including 85 (21%) of the 415 study patients.

The change in QTc interval from baseline was greater in patients who died. Despite this, the only independent predictor of mortality was older age. One possible explanation is that the decision to monitor patients with baseline QTc intervals of at least 440 msec may have skewed the study population toward people with moderate or slightly long QTc intervals prior to the initiation of HCQ/AZM, Dr. Haines suggested. Monitoring and treatment duration were short, and clinicians also likely adjusted medications when excess QTc prolongation was observed.

Although it’s been months since data collection was completed in April, and the paper was written in record-breaking time, the study “is still very relevant because the drug is still out there,” observed Dr. Haines. “Even though it may not be used in as widespread a fashion as it had been when we first submitted the paper, it is still being used routinely by many hospitals and many practitioners.”

The use of hydroxychloroquine is “going through the roof” because of COVID-19, commented Dhanunjaya Lakkireddy, MD, medical director for the Kansas City Heart Rhythm Institute, HCA Midwest Health, Overland Park, Kan., who was not involved in the study.

“This study is very relevant, and I’m glad they shared their experience, and it’s pretty consistent with the data presented by other people. The question of whether hydroxychloroquine helps people with COVID is up for debate, but there is more evidence today that it is not as helpful as it was 3 months ago,” said Dr. Lakkireddy, who is also chair of the American College of Cardiology Electrophysiology Council.

He expressed concern for patients who may be taking HCQ with other medications that have QT-prolonging effects, and for the lack of long-term protocols in place for the drug.

In the coming weeks, however, the ACC and rheumatology leaders will be publishing an expert consensus statement that addresses key issues, such as how to best to use HCQ, maintenance HCQ, electrolyte monitoring, the optimal timing of electrocardiography and cardiac magnetic imaging, and symptoms to look for if cardiac involvement is suspected, Dr. Lakkireddy said.

Asked whether HCQ and AZM should be used in COVID-19 patients, Dr. Haines said in an interview that the “QT-prolonging effects are real, the arrhythmogenic potential is real, and the benefit to patients is nil or marginal. So I think that use of these drugs is appropriate and reasonable if it is done in a setting of a controlled trial, and I support that. But the routine use of these drugs probably is not warranted based on the data that we have available.”

Still, hydroxychloroquine continues to be dragged into the spotlight in recent days as an effective treatment for COVID-19, despite discredited research and the U.S. Food and Drug Administration’s June 15 revocation of its emergency-use authorization to allow use of HCQ and chloroquine to treat certain hospitalized COVID-19 patients.

“The unfortunate politicization of this issue has really muddied the waters because the general public doesn’t know what to believe or who to believe. The fact that treatment for a disease as serious as COVID should be modulated by political affiliation is just crazy to me,” said Dr. Haines. “We should be using the best science and taking careful observations, and whatever the recommendations derived from that should be uniformly adopted by everybody, irrespective of your political affiliation.”

Dr. Haines has received honoraria from Biosense Webster, Farapulse, and Sagentia, and is a consultant for Affera, Boston Scientific, Integer, Medtronic, Philips Healthcare, and Zoll. Dr. Lakkireddy has served as a consultant to Abbott, Biosense Webster, Biotronik, Boston Scientific, and Medtronic.

A baseline QTc interval was measured with 12-lead ECG prior to treatment initiation with hydroxychloroquine 400 mg twice daily for two doses, then 200 mg twice daily for 4 days, and azithromycin 500 mg once followed by 250 mg daily for 4 days.

Because of limited availability at the time, lead II ECG telemetry monitoring over the 5-day course of HCQ/AZM was recommended only in patients with baseline QTc intervals of at least 440 msec.

Patients without an interpretable baseline ECG or available telemetry/ECG monitoring for at least 1 day were also excluded, leaving 415 patients (mean age, 64 years; 45% female) in the study population. More than half (52%) were Black, 52% had hypertension, 30% had diabetes, and 14% had cancer.

As seen in previous studies, the QTc interval increased progressively and significantly after the administration of HCQ/AZM, from 443 msec to 473 msec.

The average time to maximum QTc was 2.9 days in a subset of 135 patients with QTc measurements prior to starting therapy and on days 1 through 5.

In multivariate analysis, independent predictors of a potentially hazardous QTc interval of at least 500 msec were:

• Age older than 65 years (odds ratio, 3.0; 95% confidence interval, 1.62-5.54).
• History of  (OR, 4.65; 95% CI, 2.01-10.74).
• Admission  of at least 1.5 mg/dL (OR, 2.22; 95% CI, 1.28-3.84).
• Peak troponin I level above 0.04 mg/mL (OR, 3.89; 95% CI, 2.22-6.83).
• Body mass index below 30 kg/m² (OR for a BMI of 30 kg/m² or higher, 0.45; 95% CI, 0.26-0.78).

Concomitant use of drugs with known risk for torsade de pointes was a significant risk factor in univariate analysis (OR, 1.73; P = .036), but fell out in the multivariate model.

No patients experienced high-grade arrhythmias during the study. In all, 112 of the 586 patients died during hospitalization, including 85 (21%) of the 415 study patients.

The change in QTc interval from baseline was greater in patients who died. Despite this, the only independent predictor of mortality was older age. One possible explanation is that the decision to monitor patients with baseline QTc intervals of at least 440 msec may have skewed the study population toward people with moderate or slightly long QTc intervals prior to the initiation of HCQ/AZM, Dr. Haines suggested. Monitoring and treatment duration were short, and clinicians also likely adjusted medications when excess QTc prolongation was observed.

Although it’s been months since data collection was completed in April, and the paper was written in record-breaking time, the study “is still very relevant because the drug is still out there,” observed Dr. Haines. “Even though it may not be used in as widespread a fashion as it had been when we first submitted the paper, it is still being used routinely by many hospitals and many practitioners.”

The use of hydroxychloroquine is “going through the roof” because of COVID-19, commented Dhanunjaya Lakkireddy, MD, medical director for the Kansas City Heart Rhythm Institute, HCA Midwest Health, Overland Park, Kan., who was not involved in the study.

“This study is very relevant, and I’m glad they shared their experience, and it’s pretty consistent with the data presented by other people. The question of whether hydroxychloroquine helps people with COVID is up for debate, but there is more evidence today that it is not as helpful as it was 3 months ago,” said Dr. Lakkireddy, who is also chair of the American College of Cardiology Electrophysiology Council.

He expressed concern for patients who may be taking HCQ with other medications that have QT-prolonging effects, and for the lack of long-term protocols in place for the drug.

In the coming weeks, however, the ACC and rheumatology leaders will be publishing an expert consensus statement that addresses key issues, such as how to best to use HCQ, maintenance HCQ, electrolyte monitoring, the optimal timing of electrocardiography and cardiac magnetic imaging, and symptoms to look for if cardiac involvement is suspected, Dr. Lakkireddy said.

Asked whether HCQ and AZM should be used in COVID-19 patients, Dr. Haines said in an interview that the “QT-prolonging effects are real, the arrhythmogenic potential is real, and the benefit to patients is nil or marginal. So I think that use of these drugs is appropriate and reasonable if it is done in a setting of a controlled trial, and I support that. But the routine use of these drugs probably is not warranted based on the data that we have available.”

Still, hydroxychloroquine continues to be dragged into the spotlight in recent days as an effective treatment for COVID-19, despite discredited research and the U.S. Food and Drug Administration’s June 15 revocation of its emergency-use authorization to allow use of HCQ and chloroquine to treat certain hospitalized COVID-19 patients.

“The unfortunate politicization of this issue has really muddied the waters because the general public doesn’t know what to believe or who to believe. The fact that treatment for a disease as serious as COVID should be modulated by political affiliation is just crazy to me,” said Dr. Haines. “We should be using the best science and taking careful observations, and whatever the recommendations derived from that should be uniformly adopted by everybody, irrespective of your political affiliation.”

A new analysis from Michigan’s largest health system provides sobering verification of the risks for QT interval prolongation in COVID-19 patients treated with hydroxychloroquine and azithromycin (HCQ/AZM).

One in five patients (21%) had a corrected QT (QTc) interval of at least 500 msec, a value that increases the risk for torsade de pointes in the general population and at which cardiovascular leaders have suggested withholding HCQ/AZM in COVID-19 patients.

“One of the most striking findings was when we looked at the other drugs being administered to these patients; 61% were being administered drugs that had QT-prolonging effects concomitantly with the HCQ and AZM therapy. So they were inadvertently doubling down on the QT-prolonging effects of these drugs,” senior author David E. Haines, MD, director of the Heart Rhythm Center at William Beaumont Hospital, Royal Oak, Mich., said in an interview.

A total of 34 medications overlapped with HCQ/AZM therapy are known or suspected to increase the risk for torsade de pointes, a potentially life-threatening ventricular tachycardia. The most common of these were propofol coadministered in 123 patients, ondansetron in 114, dexmedetomidine in 54, haloperidol in 44, amiodarone in 43, and tramadol in 26.

“This speaks to the medical complexity of this patient population, but also suggests inadequate awareness of the QT-prolonging effects of many common medications,” the researchers say.

The study was published Aug. 5 in JACC Clinical Electrophysiology.

For some patients, a bout of COVID-19 may not be over after hospital discharge, acute symptoms subside, or a couple of tests for SARS-CoV-2 come back negative. Those who have reached these milestones of conquering the disease may find that their recovery journey has only begun. Debilitating symptoms such as fatigue, headache, and dyspnea may linger for weeks or longer. Patients with persistent symptoms, often referred to as “long haulers” in reference to the duration of their recovery, are looking for answers about their condition and when their COVID-19 illness will finally resolve.

Long-haul patients organize

What started as an accumulation of anecdotal evidence in social media, blogs, and the mainstream press about slow recovery and long-lasting symptoms of COVID-19 is now the focus of clinical trials in the population of recovering patients. Projects such as the COVID Symptom Study, initiated by the Massachusetts General Hospital, Boston; the Harvard School of Public Health, Boston; King’s College London; and Stanford (Calif.) University, are collecting data on symptoms from millions of patients and will eventually contribute to a better understanding of prolonged recovery.

Patients looking for answers have created groups on social media such as Facebook to exchange information about their experiences (e.g., Survivor Corps, COVID-19 Support Group, COVID-19 Recovered Survivors). Recovering patients have created patient-led research organizations (Body Politic COVID-19 Support Group) to explore persistent symptoms and begin to create data for research.
 

Some data on lingering symptoms

A small study of 143 previously hospitalized, recovering patients in Italy found that 87.4% of the cohort had at least one persistent symptom 2 months or longer after initial onset and at more than a month after discharge. In this sample, only 5% had been intubated. (JAMA 2020 Jul 9. doi: 10.1001/jama.2020.12603).

One study found that even patients who have had relatively mild symptoms and were not hospitalized can have persistent symptoms. The Centers for Disease Control and Prevention conducted a survey of adults who tested positive for the positive reverse transcription–polymerase chain reaction test for SARS-CoV-2 and found that, among the 292 respondents, 35% were still feeling the impact of the disease 2-3 weeks after testing. Fatigue (71%), cough (61%), and headache (61%) were the most commonly reported symptoms. The survey found that delayed recovery was evident in nearly a quarter of 18- to 34-year-olds and in a third of 35- to 49-year-olds who were not sick enough to require hospitalization (MMWR. 2020 Jul 24. doi: 10.15585/mmwr.mm6930e1).

Sachin Gupta, MD, FCCP, ATSF, a pulmonologist and member of the CHEST Physician editorial advisory board, has treated patients with COVID-19 and shared some of his thoughts on the problem of prolonged symptoms of COVID-19.
 

Q: Should clinicians expect to see COVID-19 patients who have symptoms persisting weeks after they are diagnosed?

Dr. Gupta: I think clinicians, especially in primary care, are already seeing many patients with lingering symptoms, both respiratory and nonrespiratory related, and debility. A few patients here in the San Francisco Bay Area that I have spoken with 4-6 weeks out from their acute illness have complained of persisting, though improving, fatigue and cough. Early studies are confirming this as a topical issue. There may be other long-lasting sequelae of COVID-19 beyond the common mild lingering symptoms. It will also be important to consider (and get more data on) to what degree asymptomatic patients develop some degree of mild inflammatory and subsequent fibrotic changes in organs like the lungs and heart

Q: How does the recovery phase of COVID-19 compare with recovery from severe influenza or ARDS?

Dr. Gupta: Most prior influenza and acute respiratory distress syndrome (ARDS) studies have provided initial follow-up at 3 months and beyond, so technically speaking, it is a little difficult to compare the symptomatology patterns in the JAMA study of 2 months on follow-up. Nevertheless, the key takeaway is that, even though few patients in the study had ARDS requiring intubation (severe disease), many patients with milder disease had significant lingering symptoms (55% with three or more symptoms) at 2 months.

This fits logically with the premise, which we have some limited data on with ARDS (N Engl J Med. 2003;348:683-93. doi: 10.1056/NEJMoa022450) and severe influenza infection survivors (Nature Sci Rep. 2017;7:17275. doi: 10.1038/s41598-017-17497-6) that varying degrees of the inflammation cascade triggered by certain viruses can lead to changes in important patient-reported outcomes, and objective measures such as pulmonary function over the long term.

Q: What can you do for patients with lingering symptoms of COVID-19 or what can you tell them about their symptoms?

Dr. Gupta: For many patients, there is fear, given the novel nature of the virus/pandemic, that their symptoms may persist long term. Acknowledgment of their symptoms is validating and important for us to recognize as we learn more about the virus. As we are finding, many patients are going online to find answers, after sometimes feeling rushed or dismissed initially in the clinical setting.

In my experience, the bar is fairly high for most patients to reach out to their physicians with complaints of lingering symptoms after acute infection. For the ones who do reach out, they tend to have either a greater constellation of symptoms or higher severity of one or two key symptoms. After assessing and, when appropriate, ruling out secondary infections or newly developed conditions, I shift toward symptom management. I encourage such patients to build up slowly. I suggest they work first on their activities of daily living (bathing, grooming), then their instrumental activities of daily living (cooking, cleaning, checking the mail), and then to engage, based on their tolerance of symptoms, to light purposeful exercise. There are many online resources for at-home exercise activities that I recommend to patients who are more debilitated; some larger centers are beginning to offer some forms of telepulmonary rehab.

Based on what we know about other causes of viral pneumonitis and ARDS, I ask such symptomatic patients to expect a slow, gradual, and in most cases a complete recovery, and depending on the individual case, I recommend pulmonary function tests and imaging that may be helpful to track that progress.

I remind myself, and patients, that our understanding may change as we learn more over time. Checking in at set intervals, even if not in person but through a phone call, can go a long way in a setting where we do not have a specific therapy, other than gradual exercise training, to help these patients recover faster. Reassurance and encouragement are vital for patients who are struggling with the lingering burden of disease and who may find it difficult to return to work or function as usual at home. The final point is to be mindful of our patient’s mental health and, where our reassurance is not enough, to consider appropriate mental health referrals.

Q: Can you handle this kind of problem with telemedicine or which patients with lingering symptoms need to come into the office – or failing that, the ED?

Dr. Gupta: Telemedicine in the outpatient setting provides a helpful tool to assess and manage patients, in my experience, with limited and straightforward complaints. Its scope is limited diagnostically (assessing symptoms and signs) as is its reach (ability to connect with elderly, disabled, or patients without/limited telemedicine access). In many instances, telemedicine limits our ability to connect with patients emotionally and build trust. Many patients who have gone through the acute illness that we see in pulmonary clinic on follow-up are older in age, and for many, video visits are not a practical solution. Telemedicine visits can sometimes present challenges for me as well in terms of thoroughly conveying lifestyle and symptom management strategies. Health literacy is typically easier to gauge and address in person.

For patients with any degree of enduring dyspnea, more so in the acute phase, I recommend home pulse oximetry for monitoring their oxygen saturation if it is financially and technically feasible for them to obtain one. Sending a patient to the ED is an option of last resort, but one that is necessary in some cases. I expect patients with lingering symptoms to tell me that symptoms may be persisting, hopefully gradually improving, and not getting worse. If post–COVID-19 symptoms such as fever, dyspnea, fatigue, or lightheadedness are new or worsening, particularly rapidly, the safest and best option I advise patients is to go to the ED for further assessment and testing. Postviral bacterial pneumonia is something we should consider, and there is some potential for aspergillosis as well.

Q: Do you have any concerns about patients with asthma, chronic obstructive pulmonary disease, or other pulmonary issues having lingering symptoms that may mask exacerbations or may cause exacerbation of their disease?

Dr. Gupta: So far, patients with chronic lung conditions do not appear to have not been disproportionately affected by the pandemic in terms of absolute numbers or percentage wise compared to the general public. I think that sheltering in place has been readily followed by many of these patients, and in addition, I assume better adherence to their maintenance therapies has likely helped. The very few cases of patients with underlying chronic obstructive pulmonary disease and interstitial lung disease that I have seen have fared very poorly when they were diagnosed with COVID-19 in the hospital. There are emerging data about short-term outcomes from severe COVID-19 infection in patients with interstitial lung disease in Europe (medRxiv. 2020 Jul 17. doi: 10.1101/2020.07.15.20152967), and from physicians treating pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension (Ann Am Thorac Soc. 2020 Jul 29. doi: 10.1513/AnnalsATS.202005-521OC). But so far, little has been published on the outcomes of mild disease in these patients with chronic lung disease.

Q: It’s still early days to know the significance of lingering symptoms. But at what point do you begin to consider the possibility of some kind of relapse? And what is your next move if the symptoms get worse?

Dr. Gupta: COVID-19 recurrence, whether because of reinfection or relapse, is a potential concern but not one that is very commonly seen so far in my purview. Generally, symptoms of post–COVID-19 infection that are lingering trend toward getting better, even if slowly. If post–COVID-19 infection symptoms are progressing (particularly if rapidly), that would be a strong indication to evaluate that patient in the ED (less likely in clinic), reswab them for SARS-CoV-2, and obtain further testing such as blood work and imaging. A significant challenge from a research perspective will be determining if coinfection with another virus is playing a role as we move closer to the fall season.

I think that sheltering in place has been readily followed by many of these patients, and in addition, I assume better adherence to their maintenance therapies has likely helped. The very few cases of patients with underlying chronic obstructive pulmonary disease and interstitial lung disease that I have seen have fared very poorly when they were diagnosed with COVID-19 in the hospital. There are emerging data about short-term outcomes from severe COVID-19 infection in patients with interstitial lung disease in Europe (medRxiv. 2020 Jul 17. doi: 10.1101/2020.07.15.20152967), and from physicians treating pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension (Ann Am Thorac Soc. 2020 Jul 29. doi: 10.1513/AnnalsATS.202005-521OC). But so far, little has been published on the outcomes of mild disease in these patients with chronic lung disease.

Q: It’s still early days to know the significance of lingering symptoms. But at what point do you begin to consider the possibility of some kind of relapse? And what is your next move if the symptoms get worse?

Dr. Gupta: COVID-19 recurrence, whether because of reinfection or relapse, is a potential concern but not one that is very commonly seen so far in my purview. Generally, symptoms of post–COVID-19 infection that are lingering trend toward getting better, even if slowly. If post–COVID-19 infection symptoms are progressing (particularly if rapidly), that would be a strong indication to evaluate that patient in the ED (less likely in clinic), reswab them for SARS-CoV-2, and obtain further testing such as blood work and imaging. A significant challenge from a research perspective will be determining if coinfection with another virus is playing a role as we move closer to the fall season.

For some patients, a bout of COVID-19 may not be over after hospital discharge, acute symptoms subside, or a couple of tests for SARS-CoV-2 come back negative. Those who have reached these milestones of conquering the disease may find that their recovery journey has only begun. Debilitating symptoms such as fatigue, headache, and dyspnea may linger for weeks or longer. Patients with persistent symptoms, often referred to as “long haulers” in reference to the duration of their recovery, are looking for answers about their condition and when their COVID-19 illness will finally resolve.

Long-haul patients organize

What started as an accumulation of anecdotal evidence in social media, blogs, and the mainstream press about slow recovery and long-lasting symptoms of COVID-19 is now the focus of clinical trials in the population of recovering patients. Projects such as the COVID Symptom Study, initiated by the Massachusetts General Hospital, Boston; the Harvard School of Public Health, Boston; King’s College London; and Stanford (Calif.) University, are collecting data on symptoms from millions of patients and will eventually contribute to a better understanding of prolonged recovery.

Patients looking for answers have created groups on social media such as Facebook to exchange information about their experiences (e.g., Survivor Corps, COVID-19 Support Group, COVID-19 Recovered Survivors). Recovering patients have created patient-led research organizations (Body Politic COVID-19 Support Group) to explore persistent symptoms and begin to create data for research.
 

Some data on lingering symptoms

A small study of 143 previously hospitalized, recovering patients in Italy found that 87.4% of the cohort had at least one persistent symptom 2 months or longer after initial onset and at more than a month after discharge. In this sample, only 5% had been intubated. (JAMA 2020 Jul 9. doi: 10.1001/jama.2020.12603).

One study found that even patients who have had relatively mild symptoms and were not hospitalized can have persistent symptoms. The Centers for Disease Control and Prevention conducted a survey of adults who tested positive for the positive reverse transcription–polymerase chain reaction test for SARS-CoV-2 and found that, among the 292 respondents, 35% were still feeling the impact of the disease 2-3 weeks after testing. Fatigue (71%), cough (61%), and headache (61%) were the most commonly reported symptoms. The survey found that delayed recovery was evident in nearly a quarter of 18- to 34-year-olds and in a third of 35- to 49-year-olds who were not sick enough to require hospitalization (MMWR. 2020 Jul 24. doi: 10.15585/mmwr.mm6930e1).

Sachin Gupta, MD, FCCP, ATSF, a pulmonologist and member of the CHEST Physician editorial advisory board, has treated patients with COVID-19 and shared some of his thoughts on the problem of prolonged symptoms of COVID-19.
 

Q: Should clinicians expect to see COVID-19 patients who have symptoms persisting weeks after they are diagnosed?

Dr. Gupta: I think clinicians, especially in primary care, are already seeing many patients with lingering symptoms, both respiratory and nonrespiratory related, and debility. A few patients here in the San Francisco Bay Area that I have spoken with 4-6 weeks out from their acute illness have complained of persisting, though improving, fatigue and cough. Early studies are confirming this as a topical issue. There may be other long-lasting sequelae of COVID-19 beyond the common mild lingering symptoms. It will also be important to consider (and get more data on) to what degree asymptomatic patients develop some degree of mild inflammatory and subsequent fibrotic changes in organs like the lungs and heart

Q: How does the recovery phase of COVID-19 compare with recovery from severe influenza or ARDS?

Dr. Gupta: Most prior influenza and acute respiratory distress syndrome (ARDS) studies have provided initial follow-up at 3 months and beyond, so technically speaking, it is a little difficult to compare the symptomatology patterns in the JAMA study of 2 months on follow-up. Nevertheless, the key takeaway is that, even though few patients in the study had ARDS requiring intubation (severe disease), many patients with milder disease had significant lingering symptoms (55% with three or more symptoms) at 2 months.

This fits logically with the premise, which we have some limited data on with ARDS (N Engl J Med. 2003;348:683-93. doi: 10.1056/NEJMoa022450) and severe influenza infection survivors (Nature Sci Rep. 2017;7:17275. doi: 10.1038/s41598-017-17497-6) that varying degrees of the inflammation cascade triggered by certain viruses can lead to changes in important patient-reported outcomes, and objective measures such as pulmonary function over the long term.

Q: What can you do for patients with lingering symptoms of COVID-19 or what can you tell them about their symptoms?

Dr. Gupta: For many patients, there is fear, given the novel nature of the virus/pandemic, that their symptoms may persist long term. Acknowledgment of their symptoms is validating and important for us to recognize as we learn more about the virus. As we are finding, many patients are going online to find answers, after sometimes feeling rushed or dismissed initially in the clinical setting.

In my experience, the bar is fairly high for most patients to reach out to their physicians with complaints of lingering symptoms after acute infection. For the ones who do reach out, they tend to have either a greater constellation of symptoms or higher severity of one or two key symptoms. After assessing and, when appropriate, ruling out secondary infections or newly developed conditions, I shift toward symptom management. I encourage such patients to build up slowly. I suggest they work first on their activities of daily living (bathing, grooming), then their instrumental activities of daily living (cooking, cleaning, checking the mail), and then to engage, based on their tolerance of symptoms, to light purposeful exercise. There are many online resources for at-home exercise activities that I recommend to patients who are more debilitated; some larger centers are beginning to offer some forms of telepulmonary rehab.

Based on what we know about other causes of viral pneumonitis and ARDS, I ask such symptomatic patients to expect a slow, gradual, and in most cases a complete recovery, and depending on the individual case, I recommend pulmonary function tests and imaging that may be helpful to track that progress.

I remind myself, and patients, that our understanding may change as we learn more over time. Checking in at set intervals, even if not in person but through a phone call, can go a long way in a setting where we do not have a specific therapy, other than gradual exercise training, to help these patients recover faster. Reassurance and encouragement are vital for patients who are struggling with the lingering burden of disease and who may find it difficult to return to work or function as usual at home. The final point is to be mindful of our patient’s mental health and, where our reassurance is not enough, to consider appropriate mental health referrals.

Q: Can you handle this kind of problem with telemedicine or which patients with lingering symptoms need to come into the office – or failing that, the ED?

Dr. Gupta: Telemedicine in the outpatient setting provides a helpful tool to assess and manage patients, in my experience, with limited and straightforward complaints. Its scope is limited diagnostically (assessing symptoms and signs) as is its reach (ability to connect with elderly, disabled, or patients without/limited telemedicine access). In many instances, telemedicine limits our ability to connect with patients emotionally and build trust. Many patients who have gone through the acute illness that we see in pulmonary clinic on follow-up are older in age, and for many, video visits are not a practical solution. Telemedicine visits can sometimes present challenges for me as well in terms of thoroughly conveying lifestyle and symptom management strategies. Health literacy is typically easier to gauge and address in person.

For patients with any degree of enduring dyspnea, more so in the acute phase, I recommend home pulse oximetry for monitoring their oxygen saturation if it is financially and technically feasible for them to obtain one. Sending a patient to the ED is an option of last resort, but one that is necessary in some cases. I expect patients with lingering symptoms to tell me that symptoms may be persisting, hopefully gradually improving, and not getting worse. If post–COVID-19 symptoms such as fever, dyspnea, fatigue, or lightheadedness are new or worsening, particularly rapidly, the safest and best option I advise patients is to go to the ED for further assessment and testing. Postviral bacterial pneumonia is something we should consider, and there is some potential for aspergillosis as well.

Q: Do you have any concerns about patients with asthma, chronic obstructive pulmonary disease, or other pulmonary issues having lingering symptoms that may mask exacerbations or may cause exacerbation of their disease?

Dr. Gupta: So far, patients with chronic lung conditions do not appear to have not been disproportionately affected by the pandemic in terms of absolute numbers or percentage wise compared to the general public. I think that sheltering in place has been readily followed by many of these patients, and in addition, I assume better adherence to their maintenance therapies has likely helped.

A new scientific statement from the American Heart Association recommends incorporating a rapid diet-screening tool into routine primary care visits to inform dietary counseling and integrating the tool into patients’ electronic health record platforms across all healthcare settings.

American Heart Association

The statement authors evaluated 15 existing screening tools and, although they did not recommend a specific tool, they did present advantages and disadvantages of some of the tools and encouraged “critical conversations” among clinicians and other specialists to arrive at a tool that would be most appropriate for use in a particular health care setting.

“The key takeaway is for clinicians to incorporate discussion of dietary patterns into routine preventive care appointments because a suboptimal diet is the No. 1 risk factor for cardiovascular disease,” Maya Vadiveloo, PhD, RD, chair of the statement group, said in an interview.

“We also wanted to touch on the fact the screening tool could be incorporated into the EHR and then used for clinical support and for tracking and monitoring the patient’s dietary patterns over time,” said Dr. Vadiveloo, assistant professor of nutrition and food sciences in the College of Health Science, University of Rhode Island, Kingston.

The statement was published online Aug. 7 in Circulation: Cardiovascular Quality and Outcomes.
 

Competing demands

Poor dietary quality has “surpassed all other mortality risk factors, accounting for 11 million deaths and about 50% of cardiovascular disease (CVD) deaths globally,” the authors wrote.

Diets deficient in fruits, vegetables, and whole grains and high in red and processed meat, added sugars, sodium, and total energy are the “leading determinants” of the risks for CVD and other conditions, so “strategies that promote holistically healthier dietary patterns to reduce chronic disease risk are of contemporary importance.”

Most clinicians and other members of health care teams “do not currently assess or counsel patients about their food and beverage intake during routine clinical care,” the authors observed.

Reasons for this may include lack of training and knowledge, insufficient time, insufficient integration of nutrition services into health care settings, insufficient reimbursement, and “competing demands during the visit,” they noted.

Dr. Vadiveloo said that an evidence-based rapid screening tool can go a long way toward helping to overcome these barriers.

“Research shows that when primary care practitioners discuss diet with patients, the patients are receptive, but we also know that clinical workloads are already very compressed, and adding another thing to a routine preventive care appointment is challenging,” she said. “So we wanted to look and see if there were already screening tools that showed promise as valid, reliable, reflective of the best science, and easy to incorporate into various types of practice settings.”
 

Top picks

The authors established “theoretical and practice-based criteria” for an optimal diet screening tool for use in the adult population (aged 20 to 75 years). The tool had to:

• Be developed or used within clinical practice in the past 10 years.
• Be evidence-based, reliable, and valid.
• Assess total dietary pattern rather than focusing on a single food or nutrient.
• Be able to be completed and scored at administration without special knowledge or software.
• Give actionable next steps and support to patients.
• Be able track and monitor dietary change over time.
• Be brief.
• Be useful for chronic disease management.

Of the 15 tools reviewed, the three that met the most theoretical and practice-based validity criteria were the Mediterranean Diet Adherence Screener (MEDAS) and its variations; the modified, shortened Rapid Eating Assessment for Participants (REAP), and the modified version of the Starting the Conversation Tool. However, the authors noted that the Powell and Greenberg Screening Tool was the “least time-intensive.”
 

One size does not fit all

No single tool will be appropriate for all practice settings, so “we would like clinicians to discuss what will work in their particular setting,” Dr. Vadiveloo emphasized.

For example, should the screening tool be completed by the clinician, a member of the health care team, or the patient? Advantages of a tool completed by clinicians or team members include collection of the information in real time, where it can be used in shared decision-making during the encounter and increased reliability because the screen has been completed by a clinician. On the other hand, the clinician might not be able to prioritize administering the screening tool during a short clinical encounter.

Advantages of a tool completed by the patient via an EHR portal is that the patient may feel less risk of judgment by the clinician or health care professional and patients can complete the screen at their convenience. Disadvantages are limited reach into underserved populations and, potentially, less reliability than clinician-administered tools.

“It is advantageous to have tools that can be administered by multiple members of health care teams to ease the demand on clinicians, if such staff is available, but in other settings, self-administration might be better, so we tried to leave it open-ended,” Dr. Vadiveloo explained.
 

‘Ideal platform’

“The EHR is the ideal platform to prompt clinicians and other members of the health care team to capture dietary data and deliver dietary advice to patients,” the authors observed.

EHRs allow secure storage of data and also enable access to these data when needed at the point of care. They are also important for documentation purposes.

The authors noted that the use of “myriad EHR platforms and versions of platforms” have created “technical challenges.” They recommended “standardized approaches” for transmitting health data that will “more seamlessly allow rapid diet screeners to be implemented in the EHR.”

They also recommended that the prototypes of rapid diet screeners be tested by end users prior to implementation within particular clinics. “Gathering these data ahead of time can improve the uptake of the application in the real world,” they stated.

Dr. Vadiveloo added that dietary counseling can be conducted by several members of a health care team, such as a dietitian, not just by the physician. Or the patient may need to be referred to a dietitian for counseling and follow-up.

The authors concluded by characterizing the AHA statement as “a call to action ... designed to accelerate efforts to make diet quality assessment an integral part of office-based care delivery by encouraging critical conversations among clinicians, individuals with diet/lifestyle expertise, and specialists in information technology.”

Dr. Vadiveloo has disclosed no relevant financial relationships. The other authors’ disclosures are listed in the original paper.

In the clinical experience of Libby Edwards, MD, the diagnosis of lichen sclerosus in a young girl often triggers worry from patients and parents alike.

“The parents are worried about the ramifications of genital diseases and they’re worried about scarring,” she said during the virtual annual meeting of the Society for Pediatric Dermatology.

Meanwhile, during the initial assessment, physicians tend to think about sexual abuse or sexually transmitted diseases as the primary culprit. “It’s really important that you consider those issues, but they’re not usually what’s going on,” said Dr. Edwards, a dermatologist who practices in Charlotte, N.C. “Also, for some reason we jump to yeast as a cause of diseases in the genital area. If the child is out of diapers and hasn’t reached puberty, it’s almost never yeast. Do a culture. Try and prove yeast. If it doesn’t respond to treatment for yeast, it’s not going to be yeast. Reassure, and don’t forget to reassure.”

The causes of lichen sclerosus in young girls are not completely understood, she continued, but a main factor is autoimmune-related, which can cause a distinctive rash that usually affects the genital skin around the vulva and anus. Lichen sclerosus presents classically as white, fragile plaques. “Textbooks say that there is cigarette paper-like crinkling of skin,” Dr. Edwards said. “I think of it being more like cellophane paper. In children, we often see it as smooth, kind of waxy and shiny, compared to adults. Children usually present with pruritus and irritation.”

Lichen sclerosus often starts in the clitoral area and on the perineum, and often with an edematous clitoral hood. “It often eventuates into clitoral phimosis, meaning that there is midline adhesion so that the clitoris is buried,” she said. “In adults, seeing this clitoral phimosis is a reliable sign of a scarring dermatosis – most often lichen sclerosus. But you can’t say that in children, because little girls will often have scarring over the clitoris. It’s just physiologic and means nothing, and it will go away at puberty. Certainly, sometimes this white discoloration can have crinkling. Purpura and tearing are common; if you look at lichen sclerosus histologically it looks like a thin epithelium that’s stretched over gelatin. Any rubbing and scratching can cause bleeding in the skin.”

Clinical appearance of well demarcated white skin with texture change drives the diagnosis. “It can be hard to tell from vitiligo at times, but there always should be texture change – whether it’s crinkling, whether it’s waxy, whether it’s smooth – and it’s symptomatic,” she said.

A biopsy is not usually required. “I think a good picture [of the affected area] or some sort of objective description in the chart is important, because most children do so well that in a few months there’s no sign of it, and the next provider [they see] may not believe that they ever had it,” she said.

The recommended initial treatment for lichen sclerosus in girls is a tiny amount of a superpotent topical corticosteroid ointment such as clobetasol or halobetasol one to two times daily until the skin is clear, which usually takes 2-4 months. “You do not treat these children until they’re comfortable, because that may be a week,” Dr. Edwards said. “You treat these children until the skin looks normal. Then you need to keep treating them, because if you don’t, the skin will relapse, even though they might not have symptoms.”

Following initial treatment, she recommends use of a superpotent corticosteroid once per day three times a week, or a midpotency steroid like triamcinolone ointment 0.1% every day. In her clinical experience, if lesions clear and remain clear with long-term treatment through puberty, the chances are good that they’ll stay clear if the medication is stopped.

“There are no studies on what to do after a patient clears,” said Dr. Edwards, chief of dermatology at Carolinas Medical Center, Charlotte, and adjunct clinical professor of dermatology at the University of North Carolina, Chapel Hill. “We have been informed by trial and error. If a child is totally clear after puberty, I will stop their medication and see them back every 3 months for about a year and a half. If they stay clear after a year and a half, I find that they stay clear. I wonder what happens at menopause. We surely don’t know.”

With consistent topical treatment, many patients will have clearing in one area of affected skin after a month or two, and it will take 3 or 4 months for the remaining area to clear. “I tend to see patients back every 6-8 weeks until they’re clear,” she said. “I do not like the idea of sending people out and saying, ‘use this medication twice a day for a month, then once a day for a month, then three times a week, then as needed.’

For patients concerned about the long-term use of topical steroids, the immunosuppressants tacrolimus and pimecrolimus are options. “They are often irritating on the vulva, but can work better than steroids for extragenital disease,” Dr. Edwards said. “Parents sometimes object to the use of a corticosteroid, but because these produce slower benefit and often burn with application, you can remind the parents that tacrolimus and pimecrolimus are not without side effects and are labeled as being associated with cancer. That often will prompt a parent to be willing to use a topical steroid. You can also point to studies that show the safety of topical steroids.”

Intralesional steroids are useful for thick lesions, but Dr. Edwards said that she has never had to use them in a child with lichen sclerosus. “I have found methotrexate to be useful in some people, but there is not one study on genital lichen sclerosus and methotrexate,” she said. “I find that about one in five patients with recalcitrant vulvar lichen sclerosus has had some benefit from methotrexate,” she added, noting that fractional CO₂ laser “is showing promise in these patients.”

Dr. Edwards concluded her remarks by noting that she has never cared for a child with vulvar lichen sclerosus who didn’t respond to topical super potent steroids, “except due to poor compliance.”

She reported having no relevant financial disclosures.

In the clinical experience of Libby Edwards, MD, the diagnosis of lichen sclerosus in a young girl often triggers worry from patients and parents alike.

“The parents are worried about the ramifications of genital diseases and they’re worried about scarring,” she said during the virtual annual meeting of the Society for Pediatric Dermatology.

Meanwhile, during the initial assessment, physicians tend to think about sexual abuse or sexually transmitted diseases as the primary culprit. “It’s really important that you consider those issues, but they’re not usually what’s going on,” said Dr. Edwards, a dermatologist who practices in Charlotte, N.C. “Also, for some reason we jump to yeast as a cause of diseases in the genital area. If the child is out of diapers and hasn’t reached puberty, it’s almost never yeast. Do a culture. Try and prove yeast. If it doesn’t respond to treatment for yeast, it’s not going to be yeast. Reassure, and don’t forget to reassure.”

The causes of lichen sclerosus in young girls are not completely understood, she continued, but a main factor is autoimmune-related, which can cause a distinctive rash that usually affects the genital skin around the vulva and anus. Lichen sclerosus presents classically as white, fragile plaques. “Textbooks say that there is cigarette paper-like crinkling of skin,” Dr. Edwards said. “I think of it being more like cellophane paper. In children, we often see it as smooth, kind of waxy and shiny, compared to adults. Children usually present with pruritus and irritation.”

Lichen sclerosus often starts in the clitoral area and on the perineum, and often with an edematous clitoral hood. “It often eventuates into clitoral phimosis, meaning that there is midline adhesion so that the clitoris is buried,” she said. “In adults, seeing this clitoral phimosis is a reliable sign of a scarring dermatosis – most often lichen sclerosus. But you can’t say that in children, because little girls will often have scarring over the clitoris. It’s just physiologic and means nothing, and it will go away at puberty. Certainly, sometimes this white discoloration can have crinkling. Purpura and tearing are common; if you look at lichen sclerosus histologically it looks like a thin epithelium that’s stretched over gelatin. Any rubbing and scratching can cause bleeding in the skin.”

Clinical appearance of well demarcated white skin with texture change drives the diagnosis. “It can be hard to tell from vitiligo at times, but there always should be texture change – whether it’s crinkling, whether it’s waxy, whether it’s smooth – and it’s symptomatic,” she said.

A biopsy is not usually required. “I think a good picture [of the affected area] or some sort of objective description in the chart is important, because most children do so well that in a few months there’s no sign of it, and the next provider [they see] may not believe that they ever had it,” she said.

The recommended initial treatment for lichen sclerosus in girls is a tiny amount of a superpotent topical corticosteroid ointment such as clobetasol or halobetasol one to two times daily until the skin is clear, which usually takes 2-4 months. “You do not treat these children until they’re comfortable, because that may be a week,” Dr. Edwards said. “You treat these children until the skin looks normal. Then you need to keep treating them, because if you don’t, the skin will relapse, even though they might not have symptoms.”

Following initial treatment, she recommends use of a superpotent corticosteroid once per day three times a week, or a midpotency steroid like triamcinolone ointment 0.1% every day. In her clinical experience, if lesions clear and remain clear with long-term treatment through puberty, the chances are good that they’ll stay clear if the medication is stopped.

Dr. Ira Weintraub, a recently retired orthopedic surgeon who now works at a medical billing consultancy, saw a hip replacement bill for over $400,000 earlier this year.

“The patient stayed in the hospital 17 days, which is only 17 times normal. The bill got paid,” mused Weintraub, chief medical officer of Portland, Oregon-based WellRithms, which helps self-funded employers and workers’ compensation insurers make sense of large, complex medical bills and ensure they pay the fair amount.

Charges like that go a long way toward explaining why hospitals are eager to restore joint replacements to pre-COVID levels as quickly as possible – an eagerness tempered only by safety concerns amid a resurgence of the coronavirus in some regions of the country. Revenue losses at hospitals and outpatient surgery centers may have exceeded $5 billion from canceled knee and hip replacements alone during a roughly two-month hiatus on elective procedures earlier this year.

The cost of joint replacement surgery varies widely – though, on average, it is in the tens, not hundreds, of thousands of dollars. Still, given the high and rapidly growing volume, it’s easy to see why joint replacement operations have become a vital chunk of revenue at most U.S. hospitals.

The rate of knee and hip replacements more than doubled from 2000 to 2015, according to inpatient discharge data from the Agency for Healthcare Research and Quality. And that growth is likely to continue: Knee replacements are expected to triple between now and 2040, with hip replacements not far behind, according to projections published last year in the Journal of Rheumatology.

Joint procedures are usually not emergencies, and they were among the first to be scrubbed or delayed when hospitals froze elective surgeries in March – and again in July in some areas plagued by renewed COVID outbreaks. Loss of the revenue has hit hospitals hard, and regaining it will be crucial to their financial convalescence.

“Without orthopedic volumes returning to something near their pre-pandemic levels, it will make it difficult for health systems to get back to anywhere near break-even from a bottom-line perspective,” said Stephen Thome, a principal in health care consulting at Grant Thornton, an advisory, audit and tax firm.

It’s impossible to know exactly how much knee and hip replacements are worth to hospitals, because no definitive data on total volume or price exists.

But using published estimates of volume, extrapolating average commercial payments from published Medicare rates based on a study, and making an educated guess of patient coinsurance, Thome helped KHN arrive at an annual market value for American hospitals and surgery centers of between $15.5 billion and $21.5 billion for knee replacements alone.

That suggests a revenue loss of $1.3 billion to $1.8 billion per month for the period the surgeries were shut down. These figures include ambulatory surgery centers not owned by hospitals, which also suspended most operations in late March, all of April and into May.

If you add hip replacements, which account for about half the volume of knees and are paid at similar rates, the total annual value rises to a range of $23 billion to $32 billion, with monthly revenue losses from $1.9 billion to $2.7 billion.

The American Hospital Association projects total revenue lost at U.S. hospitals will reach $323 billion by year’s end, not counting additional losses from surgeries canceled during the current coronavirus spike. That amount is partially offset by $69 billion in federal relief dollars hospitals have received so far, according to the association. The California Hospital Association puts the net revenue loss for hospitals in that state at about $10.5 billion, said spokesperson Jan Emerson-Shea.

Hospitals resumed joint replacement surgeries in early to mid-May, with the timing and ramp-up speed varying by region and hospital. Some hospitals restored volume quickly; others took a more cautious route and continue to lose revenue. Still others have had to shut down again.

At the NYU Langone Orthopedic Hospital in New York City, “people are starting to come in and you see the operating rooms full again,” said Dr. Claudette Lajam, chief orthopedic safety officer.

At St. Jude Medical Center in Fullerton, California, where the coronavirus is raging, inpatient joint replacements resumed in the second or third week of May – cautiously at first, but volume is “very close to pre-pandemic levels at this point,” said Dr. Kevin Khajavi, chairman of the hospital’s orthopedic surgery department. However, “we are constantly monitoring the situation to determine if we have to scale back once again,” he said.

In large swaths of Texas, elective surgeries were once again suspended in July because of the COVID-19 resurgence. The same is true at many hospitals in Florida, Alabama, South Carolina and Nevada.

The Mayo Clinic in Phoenix suspended nonemergency joint replacement surgeries in early July. It resumed outpatient replacement procedures the week of July 27, but still has not resumed nonemergency inpatient procedures, said Dr. Mark Spangehl, an orthopedic surgeon there. In terms of medical urgency, joint replacements are “at the bottom of the totem pole,” Spangehl said.

In terms of cash flow, however, joint replacements are decidedly not at the bottom of the totem pole. They have become a cash cow as the number of patients undergoing them has skyrocketed in recent decades.

The volume is being driven by an aging population, an epidemic of obesity and a significant rise in the number of younger people replacing joints worn out by years of sports and exercise.

It’s also being driven by the cash. Once only done in hospitals, the operations are now increasingly performed at ambulatory surgery centers – especially on younger, healthier patients who don’t require hospitalization.

The surgery centers are often physician-owned, but private equity groups such as Bain Capital and KKR & Co. have taken an interest in them, drawn by their high growth potential, robust financial returns and ability to offer competitive prices.

“[G]enerally the savings should be very good – but I do see a lot of outlier surgery centers where they are charging exorbitant amounts of money – $100,000 wouldn’t be too much,” said WellRithm’s Weintraub, who co-owned such a surgery center in Portland.

Fear of catching the coronavirus in a hospital is reinforcing the outpatient trend. Matthew Davis, a 58-year-old resident of Washington, was scheduled for a hip replacement on March 30 but got cold feet because of COVID-19, and canceled just before all elective surgeries were halted. When it came time to reschedule in June, he overcame his reservations in large part because the surgeon planned to perform the procedure at a free-standing surgery center.

“That was key to me – avoiding an overnight hospital stay to minimize my exposure,” Davis said. “These joint replacements are almost industrial-scale. They are cranking out joint replacements 9 to 5. I went in at 6:30 a.m. and I was walking out the door at 11:30.”

Acutely aware of the financial benefits, hospitals and surgery clinics have been marketing joint replacements for years, competing for coveted rankings and running ads that show healthy aging people, all smiles, engaged in vigorous activity.

However, a 2014 study concluded that one-third of knee replacements were not warranted, mainly because the symptoms of the patients were not severe enough to justify the procedures.

“The whole marketing of health care is so manipulative to the consuming public,” said Lisa McGiffert, a longtime consumer advocate and co-founder of the Patient Safety Action Network. “People might be encouraged to get a knee replacement, when in reality something less invasive could have improved their condition.”

McGiffert recounted a conversation with an orthopedic surgeon in Washington state who told her about a patient who requested a knee replacement, even though he had not tried any lower-impact treatments to fix the problem. “I asked the surgeon, ‘You didn’t do it, did you?’ And he said, ‘Of course I did. He would just have gone to somebody else.’ ”

It resumed outpatient replacement procedures the week of July 27, but still has not resumed nonemergency inpatient procedures, said Dr. Mark Spangehl, an orthopedic surgeon there. In terms of medical urgency, joint replacements are “at the bottom of the totem pole,” Spangehl said.

In terms of cash flow, however, joint replacements are decidedly not at the bottom of the totem pole. They have become a cash cow as the number of patients undergoing them has skyrocketed in recent decades.

The volume is being driven by an aging population, an epidemic of obesity and a significant rise in the number of younger people replacing joints worn out by years of sports and exercise.

It’s also being driven by the cash. Once only done in hospitals, the operations are now increasingly performed at ambulatory surgery centers – especially on younger, healthier patients who don’t require hospitalization.

The surgery centers are often physician-owned, but private equity groups such as Bain Capital and KKR & Co. have taken an interest in them, drawn by their high growth potential, robust financial returns and ability to offer competitive prices.

“[G]enerally the savings should be very good – but I do see a lot of outlier surgery centers where they are charging exorbitant amounts of money – $100,000 wouldn’t be too much,” said WellRithm’s Weintraub, who co-owned such a surgery center in Portland.

Fear of catching the coronavirus in a hospital is reinforcing the outpatient trend. Matthew Davis, a 58-year-old resident of Washington, was scheduled for a hip replacement on March 30 but got cold feet because of COVID-19, and canceled just before all elective surgeries were halted. When it came time to reschedule in June, he overcame his reservations in large part because the surgeon planned to perform the procedure at a free-standing surgery center.

“That was key to me – avoiding an overnight hospital stay to minimize my exposure,” Davis said. “These joint replacements are almost industrial-scale. They are cranking out joint replacements 9 to 5. I went in at 6:30 a.m. and I was walking out the door at 11:30.”

Acutely aware of the financial benefits, hospitals and surgery clinics have been marketing joint replacements for years, competing for coveted rankings and running ads that show healthy aging people, all smiles, engaged in vigorous activity.

However, a 2014 study concluded that one-third of knee replacements were not warranted, mainly because the symptoms of the patients were not severe enough to justify the procedures.

“The whole marketing of health care is so manipulative to the consuming public,” said Lisa McGiffert, a longtime consumer advocate and co-founder of the Patient Safety Action Network. “People might be encouraged to get a knee replacement, when in reality something less invasive could have improved their condition.”

McGiffert recounted a conversation with an orthopedic surgeon in Washington state who told her about a patient who requested a knee replacement, even though he had not tried any lower-impact treatments to fix the problem. “I asked the surgeon, ‘You didn’t do it, did you?’ And he said, ‘Of course I did. He would just have gone to somebody else.’ ”

When officials closed U.S. schools in March to limit the spread of COVID-19, they may have prevented more than 1 million cases over a 26-day period, a new estimate published online July 29 in JAMA suggests.

But school closures also left blind spots in understanding how children and schools affect disease transmission.

“School closures early in pandemic responses thwarted larger-scale investigations of schools as a source of community transmission,” researchers noted in a separate study, published online July 30 in JAMA Pediatrics, that examined levels of viral RNA in children and adults with COVID-19.

“Our analyses suggest children younger than 5 years with mild to moderate COVID-19 have high amounts of SARS-CoV-2 viral RNA in their nasopharynx, compared with older children and adults,” reported Taylor Heald-Sargent, MD, PhD, and colleagues. “Thus, young children can potentially be important drivers of SARS-CoV-2 spread in the general population, as has been demonstrated with respiratory syncytial virus, where children with high viral loads are more likely to transmit.”

Although the study “was not designed to prove that younger children spread COVID-19 as much as adults,” it is a possibility, Dr. Heald-Sargent, a pediatric infectious diseases specialist at Ann and Robert H. Lurie Children’s Hospital and assistant professor of pediatrics at Northwestern University, Chicago, said in a related news release. “We need to take that into account in efforts to reduce transmission as we continue to learn more about this virus.”.

The study included 145 patients with mild or moderate illness who were within 1 week of symptom onset. The researchers used reverse transcriptase–polymerase chain reaction (rt-PCR) on nasopharyngeal swabs collected at inpatient, outpatient, emergency department, or drive-through testing sites to measure SARS-CoV-2 levels. The investigators compared PCR amplification cycle threshold (CT) values for children younger than 5 years (n = 46), children aged 5-17 years (n = 51), and adults aged 18-65 years (n = 48); lower CT values indicate higher amounts of viral nucleic acid.

Median CT values for older children and adults were similar (about 11), whereas the median CT value for young children was significantly lower (6.5). The differences between young children and adults “approximate a 10-fold to 100-fold greater amount of SARS-CoV-2 in the upper respiratory tract of young children,” the researchers wrote.

“Behavioral habits of young children and close quarters in school and day care settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased,” they write.
 

Modeling the impact of school closures

In the JAMA study, Katherine A. Auger, MD, of Cincinnati Children’s Hospital Medical Center, and colleagues examined at the U.S. population level whether closing schools, as all 50 states did in March, was associated with relative decreases in COVID-19 incidence and mortality.

To isolate the effect of school closures, the researchers used an interrupted time series analysis and included other state-level nonpharmaceutical interventions and variables in their regression models.

“Per week, the incidence was estimated to have been 39% of what it would have been had schools remained open,” Dr. Auger and colleagues wrote. “Extrapolating the absolute differences of 423.9 cases and 12.6 deaths per 100,000 to 322.2 million residents nationally suggests that school closure may have been associated with approximately 1.37 million fewer cases of COVID-19 over a 26-day period and 40,600 fewer deaths over a 16-day period; however, these figures do not account for uncertainty in the model assumptions and the resulting estimates.”

Relative reductions in incidence and mortality were largest in states that closed schools when the incidence of COVID-19 was low, the authors found.
 

Decisions with high stakes

In an accompanying editorial, Julie M. Donohue, PhD, and Elizabeth Miller, MD, PhD, both affiliated with the University of Pittsburgh, emphasized that the results are estimates. “School closures were enacted in close proximity ... to other physical distancing measures, such as nonessential business closures and stay-at-home orders, making it difficult to disentangle the potential effect of each intervention.”

Although the findings “suggest a role for school closures in virus mitigation, school and health officials must balance this with academic, health, and economic consequences,” Dr. Donohue and Dr. Miller added. “Given the strong connection between education, income, and life expectancy, school closures could have long-term deleterious consequences for child health, likely reaching into adulthood.” Schools provide “meals and nutrition, health care including behavioral health supports, physical activity, social interaction, supports for students with special education needs and disabilities, and other vital resources for healthy development.”

In a viewpoint article also published in JAMA, authors involved in the creation of a National Academies of Sciences, Engineering, and Medicine reported on the reopening of schools recommend that districts “make every effort to prioritize reopening with an emphasis on providing in-person instruction for students in kindergarten through grade 5 as well as those students with special needs who might be best served by in-person instruction.

“To reopen safely, school districts are encouraged to ensure ventilation and air filtration, clean surfaces frequently, provide facilities for regular handwashing, and provide space for physical distancing,” write Kenne A. Dibner, PhD, of the NASEM in Washington, D.C., and coauthors.

Furthermore, districts “need to consider transparent communication of the reality that while measures can be implemented to lower the risk of transmitting COVID-19 when schools reopen, there is no way to eliminate that risk entirely. It is critical to share both the risks and benefits of different scenarios,” they wrote.

The JAMA modeling study received funding from the Agency for Healthcare Research and Quality and the National Institutes of Health. The NASEM report was funded by the Brady Education Foundation and the Spencer Foundation. The authors disclosed no relevant financial relationships.
