Geriatrics

Study 1 Overview (Park et al)

Objective: To examine whether implementation of a geriatric trauma clinical pathway is associated with reduced rates of delirium in older adults with traumatic injury.

Design: Retrospective case-control study of electronic health records.

Setting and participants: Eligible patients were persons aged 65 years or older who were admitted to the trauma service and did not undergo an operation. A Geriatric Trauma Care Pathway was developed by a multidisciplinary Stanford Quality Pathways team and formally launched on November 1, 2018. The clinical pathway was designed to incorporate geriatric best practices, which included order sets (eg, age-appropriate nonpharmacological interventions and pharmacological dosages), guidelines (eg, Institute for Healthcare Improvement Age-Friendly Health systems 4M framework), automated consultations (comprehensive geriatric assessment), and escalation pathways executed by a multidisciplinary team (eg, pain, bowel, and sleep regulation). The clinical pathway began with admission to the emergency department (ED) (ie, automatic trigger of geriatric trauma care admission order set), daily multidisciplinary team meetings during acute hospitalization, and a transitional care team consultation for postdischarge follow-up or home visit.

Main outcome measures: The primary outcome was delirium as determined by a positive Confusion Assessment Method (CAM) score or a diagnosis of delirium by the clinical team. The secondary outcome was hospital length of stay (LOS). Process measures for pathway compliance (eg, achieving adequate pain control, early mobilization, advance care planning) were assessed. Outcome measures were compared between patients who underwent the Geriatric Trauma Care Pathway intervention (postimplementation group) vs patients who were treated prior to pathway implementation (baseline pre-implementation group).

Main results: Of the 859 eligible patients, 712 were included in the analysis (442 [62.1%] in the baseline pre-implementation group and 270 [37.9%] in the postimplementation group); mean (SD) age was 81.4 (9.1) years, and 394 (55.3%) were women. The injury mechanism was similar between groups, with falls being the most common cause of injury (247 [55.9%] in the baseline group vs 162 [60.0%] in the postimplementation group; P = .43). Injuries as measured by Injury Severity Score (ISS) were minor or moderate in both groups (261 [59.0%] in baseline group vs 168 [62.2%] in postimplementation group; P = .87). The adjusted odds ratio (OR) for delirium in the postimplementation group was lower compared to the baseline pre-implementation group (OR, 0.54; 95% CI, 0.37-0.80; P < .001). Measures of advance care planning in the postimplementation group improved, including more frequent goals-of-care documentation (53.7% in postimplementation group vs 16.7% in baseline group; P < .001) and a shortened time to first goals-of-care discussion upon presenting to the ED (36 hours in postimplementation group vs 50 hours in baseline group; P = .03).

Conclusion: Implementation of a multidisciplinary geriatric trauma clinical pathway for older adults with traumatic injury at a single level I trauma center was associated with reduced rates of delirium.

Study 2 Overview (Bryant et al)

Objective: To determine whether an interdisciplinary care pathway for frail trauma patients can improve in-hospital mortality, complications, and 30-day readmissions.

Design: Retrospective cohort study of frail patients.

Setting and participants: Eligible patients were persons aged 65 years or older who were admitted to the trauma service and survived more than 24 hours; admitted to and discharged from the trauma unit; and determined to be pre-frail or frail by a geriatrician’s assessment. A Frailty Identification and Care Pathway designed to reduce delirium and complications in frail older trauma patients was developed by a multidisciplinary team and implemented in 2016. The standardized evidence-based interdisciplinary care pathway included utilization of order sets and interventions for delirium prevention, early ambulation, bowel and pain regimens, nutrition and physical therapy consults, medication management, care-goal setting, and geriatric assessments.

Main outcome measures: The main outcomes were delirium as determined by a positive CAM score, major complications as defined by the Trauma Quality Improvement Project, in-hospital mortality, and 30-day hospital readmission. Outcome measures were compared between patients who underwent Frailty Identification and Care Pathway intervention (postintervention group) vs patients who were treated prior to pathway implementation (pre-intervention group).

Main results: A total of 269 frail patients were included in the analysis (125 in pre-intervention group vs 144 in postintervention group). Patient demographic and admission characteristics were similar between the 2 groups: mean age was 83.5 (7.1) years, 60.6% were women, and median ISS was 10 (interquartile range [IQR], 9-14). The injury mechanism was similar between groups, with falls accounting for 92.8% and 86.1% of injuries in the pre-intervention and postintervention groups, respectively (P = .07). In univariate analysis, the Frailty Identification and Care Pathway intervention was associated with a significant reduction in delirium (12.5% vs 21.6%, P = .04) and 30-day hospital readmission (2.7% vs 9.6%, P = .01) compared to patients in the pre-intervention group. However, rates of major complications (28.5% vs 28.0%, P = 0.93) and in-hospital mortality (4.2% vs 7.2%, P = .28) were similar between the pre-intervention and postintervention groups. In multivariate logistic regression models adjusted for patient characteristics (age, sex, race, ISS), patients in the postintervention group had lower delirium (OR, 0.44; 95% CI, 0.22-0.88; P = .02) and 30-day hospital readmission (OR, 0.25; 95% CI, 0.07-0.84; P = .02) rates compared to those in the pre-intervention group.

Conclusion: Implementation of an interdisciplinary care protocol for frail geriatric trauma patients significantly decreased their risks for in-hospital delirium and 30-day hospital readmission.

Commentary

Traumatic injuries in older adults are associated with higher morbidity and mortality compared to younger patients, with falls and motor vehicle accidents accounting for a majority of these injuries. Astoundingly, up to one-third of this vulnerable population presenting to hospitals with an ISS greater than 15 may die during hospitalization.¹ As a result, a large number of studies and clinical trials have focused on interventions that are designed to reduce fall risks, and hence reduce adverse consequences of traumatic injuries that may arise after falls.² However, this emphasis on falls prevention has overshadowed a need to develop effective geriatric-centered clinical interventions that aim to improve outcomes in older adults who present to hospitals with traumatic injuries. Furthermore, frailty—a geriatric syndrome indicative of an increased state of vulnerability and predictive of adverse outcomes such as delirium—is highly prevalent in older patients with traumatic injury.³ Thus, there is an urgent need to develop novel, hospital-based, traumatic injury–targeting strategies that incorporate a thoughtful redesign of the care framework that includes evidence-based interventions for geriatric syndromes such as delirium and frailty.

The study reported by Park et al (Study 1) represents the latest effort to evaluate inpatient management strategies designed to improve outcomes in hospitalized older adults who have sustained traumatic injury. Through the implementation of a novel multidisciplinary Geriatric Trauma Care Pathway that incorporates geriatric best practices, this intervention was found to be associated with a 46% lower risk of in-hospital delirium. Because of the inclusion of all age-eligible patients across all strata of traumatic injuries, rather than preselecting for those at the highest risk for poor clinical outcomes, the benefits of this intervention extend to those with minor or moderate injury severity. Furthermore, the improvement in delirium (ie, the primary outcome) is particularly meaningful given that delirium is one of the most common hospital-associated complications that increase hospital LOS, discharge to an institution, and mortality in older adults. Finally, the study’s observed reduced time to a first goals-of-care discussion and increased frequency of goals-of-care documentation after intervention should not be overlooked. The improvements in these 2 process measures are highly significant given that advanced care planning, an intervention that helps to align patients’ values, goals, and treatments, is completed at substantially lower rates in older adults in the acute hospital setting.⁴

Similarly, in an earlier published study, Bryant and colleagues (Study 2) also show that a geriatric-focused interdisciplinary trauma care pathway is associated with delirium risk reduction in hospitalized older trauma patients. Much like Study 1, the Frailty Identification and Care Pathway utilized in Study 2 is an evidence-based interdisciplinary care pathway that includes the use of geriatric assessments, order sets, and geriatric best practices. Moreover, its exclusive inclusion of pre-frail and frail older patients (ie, those at higher risk for poor outcomes) with moderate injury severity (median ISS of 10 [IQR, 9-14]) suggests that this type of care pathway benefits hospitalized older trauma patients, who are particularly vulnerable to adverse complications such as delirium. Moreover, the successful utilization of the FRAIL questionnaire, a validated frailty screening tool, by surgical residents in the ED to initiate this care pathway demonstrates the feasibility of its use in expediting frailty screening in older patients in trauma care.

Application for Clinical Practice and System Implementation

Findings from the 2 studies discussed in this review indicate that implementation of interdisciplinary clinical care pathways predicated on evidence-based geriatric principles and best practices is a promising approach to reduce delirium in hospitalized older trauma patients. These studies have helped to lay the groundwork in outlining the roadmaps (eg, processes and infrastructures) needed to create such clinical pathways. These key elements include: (1) integration of a multidisciplinary committee (eg, representation from trauma, emergency, and geriatric medicine, nursing, physical and occupational therapy, pharmacy, social work) in pathway design and implementation; (2) adaption of evidence-based geriatric best practices (eg, the Institute for Healthcare Improvement Age-Friendly Health System 4M framework [medication, mentation, mobility, what matters]) to prioritize interventions and to design a pathway that incorporates these features; (3) incorporation of comprehensive geriatric assessment by interdisciplinary providers; (4) utilization of validated clinical instruments to assess physical and cognitive functions, frailty, delirium, and social determinants of health; (5) modification of electronic health record systems to encompass order sets that incorporate evidence-based, nonpharmacological and pharmacological interventions to manage symptoms (eg, delirium, pain, bowel movement, sleep, immobility, polypharmacy) essential to quality geriatric care; and (6) integration of patient and caregiver preferences via goals-of-care discussions and corresponding documentation and communication of these goals.

Additionally, these 2 studies imparted some strategies that may facilitate the implementation of interdisciplinary clinical care pathways in trauma care. Examples of such facilitators include: (1) collaboration with champions within each specialty to reinforce education and buy-in; (2) creation of automatically triggered order sets upon patient presentation to the ED that unites distinct features of clinical pathways; (3) adaption and reorganization of existing hospital infrastructures and resources to meet the needs of clinical pathways implementation (eg, utilizing information technology resources to develop electronic health record order sets; using quality department to develop clinical pathway guidelines and electronic outcome dashboards); and (4) development of individualized patient and caregiver education materials based on care needs (eg, principles of delirium prevention and preservation of mobility during hospitalization) to prepare and engage these stakeholders in patient care and recovery.

Practice Points

• A geriatric interdisciplinary care model can be effectively applied to the management of acute trauma in older patients.
• Interdisciplinary clinical pathways should incorporate geriatric best practices and guidelines and age-appropriate order sets to prioritize and integrate care.

Older adults who have spent time in the intensive care unit have double the risk of developing dementia in later years, compared with older adults who have never stayed in the ICU, new research suggests.

“ICU hospitalization may be an underrecognized risk factor for dementia in older adults,” Bryan D. James, PhD, epidemiologist with Rush Alzheimer’s Disease Center, Chicago, said in an interview.

“Health care providers caring for older patients who have experienced a hospitalization for critical illness should be prepared to assess and monitor their patients’ cognitive status as part of their long-term care plan,” Dr. James added.

The findings were presented at the Alzheimer’s Association International Conference.
 

Hidden risk factor?

ICU hospitalization as a result of critical illness has been linked to subsequent cognitive impairment in older patients. However, how ICU hospitalization relates to the long-term risk of developing Alzheimer’s and other age-related dementias is unknown.

“Given the high rate of ICU hospitalization in older persons, especially during the COVID-19 pandemic, it is critical to explore this relationship, Dr. James said.

The Rush team assessed the impact of an ICU stay on dementia risk in 3,822 older adults (mean age, 77 years) without known dementia at baseline participating in five diverse epidemiologic cohorts.

Participants were checked annually for development of Alzheimer’s and all-type dementia using standardized cognitive assessments.

Over an average of 7.8 years, 1,991 (52%) adults had at least one ICU stay; 1,031 (27%) had an ICU stay before study enrollment; and 961 (25%) had an ICU stay during the study period.

In models adjusted for age, sex, education, and race, ICU hospitalization was associated with 63% higher risk of Alzheimer’s dementia (hazard ratio, 1.63; 95% confidence interval, 1.41-1.88) and 71% higher risk of all-type dementia (HR, 1.71; 95% CI, 1.48-1.97).

In models further adjusted for other health factors such as vascular risk factors and disease, other chronic medical conditions and functional disabilities, the association was even stronger: ICU hospitalization was associated with roughly double the risk of Alzheimer’s dementia (HR 2.10; 95% CI, 1.66-2.65) and all-type dementia (HR, 2.20; 95% CI, 1.75-2.77).

Dr. James said in an interview that it remains unclear why an ICU stay may raise the dementia risk.

“This study was not designed to assess the causes of the higher risk of dementia in persons who had ICU hospitalizations. However, researchers have looked into a number of factors that could account for this increased risk,” he explained.

One is critical illness itself that leads to hospitalization, which could result in damage to the brain; for example, severe COVID-19 has been shown to directly harm the brain, Dr. James said.

He also noted that specific events experienced during ICU stay have been shown to increase risk for cognitive impairment, including infection and severe sepsis, acute dialysis, neurologic dysfunction and delirium, and sedation.
 

Important work

Commenting on the study, Heather Snyder, PhD, vice president of medical & scientific relations at the Alzheimer’s Association, said what’s interesting about the study is that it looks at individuals in the ICU, regardless of the cause.

“The study shows that having some type of health issue that results in some type of ICU stay is associated with an increased risk of declining cognition,” Dr. Snyder said.

“That’s really important,” she said, “especially given the increase in individuals, particularly those 60 and older, who did experience an ICU stay over the last couple of years and understanding how that might impact their long-term risk related to Alzheimer’s and other changes in memory.”

“If an individual has been in the ICU, that should be part of the conversation with their physician or health care provider,” Dr. Snyder advised.

The study was funded by the National Institute on Aging. Dr. James and Dr. Snyder disclosed no relevant financial relationships.

Susan Snead used to live in an apartment complex for older adults. The complex had a nice dayroom, and neighbors would knock on her door every now and then to check in.

But despite not being lonely, Ms. Snead, 89, did live alone in downtown Charleston, S.C. Eventually, that became dangerous.

“I fell a few times,” she says. “I had to call somebody to come and get me up.”

Sometimes help would come from the apartment complex’s office. Sometimes it came with a police escort.

Over time, needing to make those calls became a burden. Making and keeping appointments with her doctor, something she had to do regularly, as she has diabetes, got harder, too.

“It kind of wore me out,” she says. “Like you’re going up a hill.”

As she was beginning to accept she could no longer live alone, Ms. Snead, an Air Force veteran, learned about a program run by the Department of Veterans Affairs called Medical Foster Home.

Medical foster homes are privately owned homes in which a licensed caregiver lives with and supervises residents around the clock. Caregivers help aging veterans with activities of daily living like bathing, cooking, making and getting to appointments, getting dressed, and taking daily medication.

Caregivers can take care of up to three residents in their home at a time. While most residents are veterans, caregivers sometimes care for non-veteran residents, such as a veteran’s spouse or a caregiver’s family member.

Veterans typically pay about $1,500 to $3,000 out-of-pocket per month for the service, depending on location.

According to the VA, the concept of medical foster homes has been around since 1999, when VA hospitals across the country began reaching out to people willing to provide live-in care for veterans. The option is led by local VA hospitals, which approve caregivers and provide administrative services. There are now 517 medical foster homes, the VA says.

Much like other residential care facilities, medical foster homes get regular inspections for safety, nutrition, and more.

In 2019, Ms. Snead signed up for the program. She expected to be cared for, but she found a sense of family with her caregiver, Wilhelmina Brown, and another veteran in the home.

Ms. Brown started taking care of people – but not necessarily veterans – in 1997 when her grandmother was unable to care for herself, she says.

“My grandmama carried me to church every Sunday, she carried me to the beach – everywhere she went, she took me with her,” Ms. Brown says. As her grandmother got older, “I said, ‘I’m going to take care of her in my home.’ ”

Caring for others must come from the heart, Ms. Brown says.

She cooks her residents’ meals three times a day with dietary restrictions in mind, washes their dishes, does their laundry, remembers birthdays, and plans little parties.

“That’s my family,” Ms. Brown says.

In 2020, the COVID-19 pandemic upended the world – but at the same time, it highlighted the advantages of the medical foster home model.

Home-based primary care keeps veterans out of nursing homes – something that became particularly important as COVID-19 hit nursing homes and long-term care facilities.

Caregivers in the system were also able to help veterans, often living in rural areas, pivot and adapt to telehealth during a time of crisis.

One study, published in the journal Geriatrics, set out to identify how medical foster homes were able to deliver safe, effective health care during the early stages of the pandemic.

Researchers interviewed 37 VA care providers at 16 rural medical foster home programs across the country. The interviews took place between December 2020 and February 2021. They found medical foster home caregivers, coordinators, and health care providers communicated to move office visits to the home, helped veterans navigate telehealth, advocated to get veterans vaccinated in-home, and relied on each other to fight social isolation.

Caregivers also adapted quickly to telehealth, according to Leah Haverhals, PhD, a health research scientist and communications director for the Seattle-Denver Center of Innovation for Veteran Centered and Value Driven Care, who led the study.

Most veterans in the foster home program are older and find new technology difficult to use.

Caregivers, coordinators, and health care providers were largely new to the technology, too.

While the study found that most veterans and caregivers preferred in-person care, they were able to work together to make the best of telehealth.

“That speaks to the nature of the care being given, being able to pivot in a crisis like that,” Dr. Haverhals says.

If caregivers didn’t already have computers or telehealth-compatible devices, the VA provided iPads that would connect to the internet using cellular signals. According to the study, this helped to overcome connectivity issues that may have caused problems in rural areas.

Ms. Snead says Ms. Brown helped a lot with her telehealth calls.

“If we had to do things over the phone or with video, she was able to set that up to work with the person on the other end. She knows a lot about that stuff – about computers and things like that,” Ms. Snead says, adding that she hadn’t worked with computers since retirement in 1998.

Telehealth helped health care providers identify infections and quickly prescribe antibiotics to veterans in rural areas and provide other care that was more safely delivered in private homes.

“The findings from our study highlighted that when working together for the common goal of keeping vulnerable populations like veterans in MFHs [medical foster homes] safe during times of crisis, adaptation and collaboration facilitated the ongoing provision of high-quality care,” Dr. Haverhals’s group wrote. “Such collaboration has been shown to be critical in recent research in the United States on supporting older adults during the pandemic.”

Cari Levy, MD, PhD, a professor at the University of Colorado at Denver, Aurora, and a co-author of the study, specializes in palliative and telenursing home care for the VA.

Dr. Levy, who has worked for the VA for about 20 years, says how medical foster homes provided care during the pandemic carries lessons for civilian clinics. One of the most important lessons, she says, is that medical professionals will need to provide more care where people are, especially in populations that are too sick to get to the clinic.

“For years, there was all this hope that telehealth would expand,” but it took a pandemic to authorize approval from federal agencies to explode, she says. “I shudder to think what would have happened if we didn’t have telehealth. Fortunately, it was the right time to be able to flip a switch.”

Crisis aside, Dr. Levy says her dream would be for health care providers to do more home-based care. The model allows people to preserve the relational aspects of medicine, which can counteract a lot of the moral injury and burnout in the field, she says, adding:

“I see this as the kind of medicine many people intended to do when they got into medicine.”

A U.S. neuroscientist claims that some of the studies of the experimental agent, simufilam (Cassava Sciences), a drug that targets amyloid beta (Abeta) in Alzheimer’s disease (AD), are flawed, and, as a result, has taken his concerns to the National Institutes of Health.

Matthew Schrag, MD, PhD, department of neurology, Vanderbilt University Medical Center, Nashville, Tenn., uncovered what he calls inconsistencies in major studies examining the drug.

In a whistleblower report to the NIH about the drug, Dr. Schrag claims that several prominent investigators altered images and reused them over years to support the hypothesis that buildup of amyloid in the brain causes AD. The NIH has funded research into Abeta as a potential cause of AD to the tune of millions of dollars for years.

“This hypothesis has been the central dominant thinking of the field,” Dr. Schrag told this news organization. “A lot of the therapies that have been developed and tested clinically over the last decade focused on the amyloid hypothesis in one formulation or another. So, it’s an important component of the way we think about Alzheimer’s disease,” he added.

In an in-depth article published in Science and written by investigative reporter Charles Piller, Dr. Schrag said he became involved after a colleague suggested he work with an attorney investigating simufilam. The lawyer paid Dr. Schrag $18,000 to investigate the research behind the agent. Cassava Sciences denies any misconduct, according to the article.

Dr. Schrag ran many AD studies through sophisticated imaging software. The effort revealed multiple Western blot images – which scientists use to detect the presence and amount of proteins in a sample – that appeared to be altered.
 

High stakes

Dr. Schrag found “apparently altered or duplicated images in dozens of journal articles,” the Science article states.

“A lot is at stake in terms of getting this right and it’s also important to acknowledge the limitations of what we can do. We were working with what’s published, what’s publicly available, and I think that it raises quite a lot of red flags, but we’ve also not reviewed the original material because it’s simply not available to us,” Dr. Schrag said in an interview.

However, he added that despite these limitations he believes “there’s enough here that it’s important for regulatory bodies to take a closer look at it to make sure that the data is right.”

Science reports that it launched its own independent review, asking several neuroscience experts to also review the research. They agreed with Dr. Schrag’s overall conclusions that something was amiss.

Many of the studies questioned in the whistleblower report involve Sylvain Lesné, PhD, who runs The Lesné Laboratory at the University of Minnesota, Minneapolis, and is an associate professor of neuroscience. His colleague Karen Ashe, MD, PhD, a professor of neurology at the same institution, was also mentioned in the whistleblower report. She was coauthor of a 2006 report in Nature that identified an Abeta subtype as a potential culprit behind AD.

This news organization reached out to Dr. Lesné and Dr. Ashe for comment, but has not received a response.

However, an email from a University of Minnesota spokesperson said the institution is “aware that questions have arisen regarding certain images used in peer-reviewed research publications authored by University faculty Dr. Ashe and Dr. Lesné. The University will follow its processes to review the questions any claims have raised. At this time, we have no further information to provide.”
 

A matter of trust

Dr. Schrag noted the “important trust relationship between patients, physicians and scientists. When we’re exploring diseases that we don’t have good treatments for.” He added that when patients agree to participate in trials and accept the associated risks, “we owe them a very high degree of integrity regarding the foundational data.”

Dr. Schrag also pointed out that there are limited resources to study these diseases. “There is some potential for that to be misdirected. It’s important for us to pay attention to data integrity issues, to make sure that we’re investing in the right places.”

The term “fraud” does not appear in Dr. Schrag’s whistleblower report, nor does he claim misconduct in the report. However, his work has spurred some independent, ongoing investigation into the claims by several journals that published the works in question, including Nature and Science Signaling.

Dr. Schrag said that if his findings are validated through an investigation he would like to see the scientific record corrected.

“Ultimately, I’d like to see a new set of hypotheses given a chance to look at this disease from a new perspective,” he added.

Dr. Schrag noted that the work described in the Science article was performed outside of his employment with Vanderbilt University Medical Center and that his opinions do not necessarily represent the views of Vanderbilt University or Vanderbilt University Medical Center.

A U.S. neuroscientist claims that some of the studies of the experimental agent, simufilam (Cassava Sciences), a drug that targets amyloid beta (Abeta) in Alzheimer’s disease (AD), are flawed, and, as a result, has taken his concerns to the National Institutes of Health.

Matthew Schrag, MD, PhD, department of neurology, Vanderbilt University Medical Center, Nashville, Tenn., uncovered what he calls inconsistencies in major studies examining the drug.

In a whistleblower report to the NIH about the drug, Dr. Schrag claims that several prominent investigators altered images and reused them over years to support the hypothesis that buildup of amyloid in the brain causes AD. The NIH has funded research into Abeta as a potential cause of AD to the tune of millions of dollars for years.

“This hypothesis has been the central dominant thinking of the field,” Dr. Schrag told this news organization. “A lot of the therapies that have been developed and tested clinically over the last decade focused on the amyloid hypothesis in one formulation or another. So, it’s an important component of the way we think about Alzheimer’s disease,” he added.

In an in-depth article published in Science and written by investigative reporter Charles Piller, Dr. Schrag said he became involved after a colleague suggested he work with an attorney investigating simufilam. The lawyer paid Dr. Schrag $18,000 to investigate the research behind the agent. Cassava Sciences denies any misconduct, according to the article.

Dr. Schrag ran many AD studies through sophisticated imaging software. The effort revealed multiple Western blot images – which scientists use to detect the presence and amount of proteins in a sample – that appeared to be altered.
 

High stakes

Dr. Schrag found “apparently altered or duplicated images in dozens of journal articles,” the Science article states.

“A lot is at stake in terms of getting this right and it’s also important to acknowledge the limitations of what we can do. We were working with what’s published, what’s publicly available, and I think that it raises quite a lot of red flags, but we’ve also not reviewed the original material because it’s simply not available to us,” Dr. Schrag said in an interview.

However, he added that despite these limitations he believes “there’s enough here that it’s important for regulatory bodies to take a closer look at it to make sure that the data is right.”

In an online statement the U.S. Centers for Disease Control and Prevention announced its decision to recommend higher-dose and adjuvanted influenza vaccines for people aged 65 years or older. Fluzone High-Dose Quadrivalent, Flublok Quadrivalent, and Fluad Quadrivalent flu vaccines are among those specified in the release.

The organization says that these higher-dose vaccines may be more effective for the aging population, who often have difficulty mounting a strong enough immune response to protect themselves against the flu virus. People older than 65 years struggle the most during flu season and have the highest proportion of hospitalizations and deaths from flu, according to the release.

But the CDC believes that higher-dose vaccines have the potential to better protect against that danger. One study, from The New England Journal of Medicine, reported that high-dose/adjuvanted vaccines prevented flu in older patients 24% better than did lower-dose/nonadjuvanted vaccines.

These types of vaccines work by creating a larger immune response than a standard vaccine dose. In particular, adjuvanted vaccines contain an extra ingredient within them that helps the immune system produce a stronger reaction to the vaccine. These may be things like aluminum salts, which signal the body to respond faster. Higher-dose vaccines similarly promote a stronger immune response by having more particles of the target virus in their mixture. In theory, this means the body will create an enhanced response to the vaccine. For example, a higher-dose vaccine may quadruple the amount of antigens, compared with the standard dose.

The hope is that this recommendation may increase vaccine use across the board, says José Romero, MD, the director of the CDC’s National Center for Immunization and Respiratory Diseases. As quoted in the CDC announcement, Dr. Romero said that this may help reduce racial inequities in access to flu vaccines. A 2019 meta-analysis concluded that Black and Hispanic people are around 30%-40% less likely to get the flu vaccine. So increasing the access to this medication “could help reduce health disparities by making these vaccines more available to racial and ethnic minority groups,” said Dr. Romero.

The decision, spearheaded by CDC Director Rochelle Walensky, MD, follows recommendations from the Advisory Committee on Immunization Practices, which presented on this topic during a June 22 meeting. It is now part of official CDC policy and will continue to be developed as the 2022-2023 flu season approaches.

In addition, the organization says they’ll reveal more details for their plan later this summer, in their Morbidity and Mortality Weekly Report (MMWR). For now, seniors should know that they should try to get the recommended high-dose vaccines, but if they can’t, then a standard dose of whatever their provider has on hand will do.

At this point, there is still no specific vaccine recommendation for people aged under 65 years. The CDC historically avoids specifying one type of vaccine over another and says each should still be effective in younger patients.

Posttraumatic stress disorder (PTSD) is associated with accelerated cognitive decline over time, new research suggests.

In an analysis of more than 12,000 middle-aged women who had experienced at least one trauma in their lives, those with PTSD symptoms showed an approximately twofold faster decline in cognition during follow-up compared with those who did not have PTSD symptoms.

These associations were not fully explained by other known cognition-related factors such as depression, the researchers noted.

“PTSD may increase the risk of dementia by accelerating cognitive decline at midlife,” coinvestigator Jiaxuan Liu, a doctoral candidate at Harvard TH Chan School of Public Health, Boston, said in an interview.

“Our findings may suggest the value of earlier cognitive screening among individuals with PTSD and the importance of PTSD prevention and treatment across the lifespan,” she added.

The results were published online in JAMA Network Open.

Vital public health issue

“Cognitive decline at midlife and older is of vital public health interest,” Ms. Liu said. “It is a risk factor for a variety of poor health outcomes and strongly predicts Alzheimer’s disease and other dementias.

Although PTSD has been linked to lower cognitive function and dementia incidence, it has not been known whether it is associated with decline in cognitive function, she added.

“In addition, both PTSD and dementia are more common in women than men, so it’s important to understand a possible link,” Ms. Liu said.

Because no large-scale study had examined whether PTSD is associated with cognitive decline in women, the current researchers examined PTSD symptoms and their association with repeated measures of cognitive function among a large civilian trauma-exposed cohort of women aged 50-70 years at study baseline.

Participants were drawn from the Nurses’ Health Study II, a longitudinal study of a cohort of 116,429 U.S. female nurses who were between 25 and 42 years old at enrollment in 1989. Participants completed biennial questionnaires, with follow-up on an ongoing basis.

The current analysis included 12,270 trauma-exposed women (mean age at baseline, 61.1 years) who completed assessments every 1 or 12 months for up to 24 months after baseline. The mean follow-up time was 0.9 years.

In the study population, 95.9% were non-Hispanic White, 1.3% were Hispanic, 1% were Asian, 0.6% were Black, and 1.2% were classified as “other.”
 

Higher depression scores

Lifetime trauma exposure and PTSD symptoms were assessed from March 1, 2008, to Feb. 28, 2010, using the Short Screening Scale for DSM-IV PTSD.

In total, 67% of the participants reported experiencing PTSD symptoms. The women were divided into four groups, on the basis of symptom number: no PTSD symptoms (n = 4,052), one to three PTSD symptoms (n = 5,058), four to five PTSD symptoms (n = 2,018), and six to seven PTSD symptoms (n = 1,052).

The Cogstate Brief Battery, a validated and self-administered online cognitive assessment, was completed by participants between Oct. 3, 2014, and July 30, 2019. The researchers measured cognitive function with two composite scores: psychomotor speed and attention, and learning and working memory.

Covariates potentially associated with cognitive decline included demographic, educational, and behavior-related health factors such as body mass index, physical activity, cigarette smoking, diet quality, and alcohol consumption.

The researchers conducted secondary analyses that adjusted for symptoms and history of depression as well as the consequences of potential practice effects of taking the test multiple times.

Behavior-related health factors “did not substantially differ by PTSD symptom level,” the investigators noted. However, compared with women who did not have PTSD symptoms, those who had such symptoms had higher depressive symptom scores and higher rates of clinician-diagnosed depression.

Both cognitive composite scores improved through the follow-up period, “likely because of practice effects,” the researchers wrote. But after adjusting for practice effects, they found a decline over time in both composite scores.
 

Dose-related trajectories

Results showed that having more PTSD symptoms was associated with dose-related poorer cognitive trajectories.

After adjustment for demographic characteristics, women with the highest symptom level (six to seven symptoms) had a significantly worse rate of change in both composite domains of learning and working memory (beta = −0.08 SD/y; 95% confidence interval [CI], −0.11 to −0.04 SD/y; P < .001) and of psychomotor speed and attention (beta = −0.05 SD/y; 95% CI, −0.09 to −0.01 SD/y; P  = .02) compared with women with no PTSD symptoms.

Women with four to five PTSD symptoms showed a worse rate of change in learning and working memory compared with those who had no symptoms, but not in psychomotor speed and attention. Women with one to three PTSD symptoms had cognitive scores similar to those of women without PTSD symptoms.

Notably, the associations of PTSD with cognitive change remained evident after additional adjustment for behavioral factors and health conditions – and were only “partially attenuated but still evident” after further adjustment for practice effects and comorbid depression, the investigators wrote.

“We thought PTSD might be associated with worse cognitive decline through health behaviors like smoking and alcohol drinking and higher risk of other health conditions like hypertension and depression,” Ms. Liu said.

However, those factors did not account for the current study’s findings, she noted.

“We could not determine why women with PTSD had faster cognitive decline than those without PTSD,” she said.

Ms. Liu suggested that PTSD “may have effects on the brain, such as altering brain structures and affecting brain immune function.” However, more research is needed “to investigate these mechanisms that might underlie the association we found between PTSD and cognitive decline,” she said.
 

Neurotoxic effect

In a comment, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, said, “It is well known that stress is neurotoxic, and PTSD is a particularly serious form of stress.”

Dr. Fillit, clinical professor of geriatric medicine and palliative care, medicine, and neuroscience at Mount Sinai Hospital, New York, was not involved with the study.

“We tend to think of PTSD in postacute settings, such as soldiers returning from war,” he said. “This study contributes to our understanding of the long-term effects of PTSD on cognitive decline, measured objectively over time”

Dr. Fillit noted that an important implication is that, by increasing the risk for cognitive decline, PTSD also increases risk for Alzheimer’s disease. This leads to the “main take-home, which is that PTSD is a risk factor not only for cognitive decline but also for Alzheimer’s and related dementias,” he said.

However, this opens a potential therapeutic approach, Dr. Fillit added.

Because cortisol and other stress hormones drive the stress response, finding ways to block the neurotoxic effects of these hormones “might be a target to prevent cognitive decline and decrease Alzheimer’s disease risk,” he said.

The study was supported by grants from the National Institute of Mental Health and the National Institutes of Health. Ms. Liu and Dr. Fillit report no relevant financial relationships.

In an analysis of more than 12,000 middle-aged women who had experienced at least one trauma in their lives, those with PTSD symptoms showed an approximately twofold faster decline in cognition during follow-up compared with those who did not have PTSD symptoms.

These associations were not fully explained by other known cognition-related factors such as depression, the researchers noted.

“PTSD may increase the risk of dementia by accelerating cognitive decline at midlife,” coinvestigator Jiaxuan Liu, a doctoral candidate at Harvard TH Chan School of Public Health, Boston, said in an interview.

“Our findings may suggest the value of earlier cognitive screening among individuals with PTSD and the importance of PTSD prevention and treatment across the lifespan,” she added.

The results were published online in JAMA Network Open.

Vital public health issue

“Cognitive decline at midlife and older is of vital public health interest,” Ms. Liu said. “It is a risk factor for a variety of poor health outcomes and strongly predicts Alzheimer’s disease and other dementias.

Although PTSD has been linked to lower cognitive function and dementia incidence, it has not been known whether it is associated with decline in cognitive function, she added.

“In addition, both PTSD and dementia are more common in women than men, so it’s important to understand a possible link,” Ms. Liu said.

Because no large-scale study had examined whether PTSD is associated with cognitive decline in women, the current researchers examined PTSD symptoms and their association with repeated measures of cognitive function among a large civilian trauma-exposed cohort of women aged 50-70 years at study baseline.

Participants were drawn from the Nurses’ Health Study II, a longitudinal study of a cohort of 116,429 U.S. female nurses who were between 25 and 42 years old at enrollment in 1989. Participants completed biennial questionnaires, with follow-up on an ongoing basis.

The current analysis included 12,270 trauma-exposed women (mean age at baseline, 61.1 years) who completed assessments every 1 or 12 months for up to 24 months after baseline. The mean follow-up time was 0.9 years.

In the study population, 95.9% were non-Hispanic White, 1.3% were Hispanic, 1% were Asian, 0.6% were Black, and 1.2% were classified as “other.”
 

Higher depression scores

Lifetime trauma exposure and PTSD symptoms were assessed from March 1, 2008, to Feb. 28, 2010, using the Short Screening Scale for DSM-IV PTSD.

In total, 67% of the participants reported experiencing PTSD symptoms. The women were divided into four groups, on the basis of symptom number: no PTSD symptoms (n = 4,052), one to three PTSD symptoms (n = 5,058), four to five PTSD symptoms (n = 2,018), and six to seven PTSD symptoms (n = 1,052).

The Cogstate Brief Battery, a validated and self-administered online cognitive assessment, was completed by participants between Oct. 3, 2014, and July 30, 2019. The researchers measured cognitive function with two composite scores: psychomotor speed and attention, and learning and working memory.

Covariates potentially associated with cognitive decline included demographic, educational, and behavior-related health factors such as body mass index, physical activity, cigarette smoking, diet quality, and alcohol consumption.

The researchers conducted secondary analyses that adjusted for symptoms and history of depression as well as the consequences of potential practice effects of taking the test multiple times.

Behavior-related health factors “did not substantially differ by PTSD symptom level,” the investigators noted. However, compared with women who did not have PTSD symptoms, those who had such symptoms had higher depressive symptom scores and higher rates of clinician-diagnosed depression.

Both cognitive composite scores improved through the follow-up period, “likely because of practice effects,” the researchers wrote. But after adjusting for practice effects, they found a decline over time in both composite scores.
 

Dose-related trajectories

Results showed that having more PTSD symptoms was associated with dose-related poorer cognitive trajectories.

After adjustment for demographic characteristics, women with the highest symptom level (six to seven symptoms) had a significantly worse rate of change in both composite domains of learning and working memory (beta = −0.08 SD/y; 95% confidence interval [CI], −0.11 to −0.04 SD/y; P < .001) and of psychomotor speed and attention (beta = −0.05 SD/y; 95% CI, −0.09 to −0.01 SD/y; P  = .02) compared with women with no PTSD symptoms.

Women with four to five PTSD symptoms showed a worse rate of change in learning and working memory compared with those who had no symptoms, but not in psychomotor speed and attention. Women with one to three PTSD symptoms had cognitive scores similar to those of women without PTSD symptoms.

Notably, the associations of PTSD with cognitive change remained evident after additional adjustment for behavioral factors and health conditions – and were only “partially attenuated but still evident” after further adjustment for practice effects and comorbid depression, the investigators wrote.

“We thought PTSD might be associated with worse cognitive decline through health behaviors like smoking and alcohol drinking and higher risk of other health conditions like hypertension and depression,” Ms. Liu said.

However, those factors did not account for the current study’s findings, she noted.

“We could not determine why women with PTSD had faster cognitive decline than those without PTSD,” she said.

Ms. Liu suggested that PTSD “may have effects on the brain, such as altering brain structures and affecting brain immune function.” However, more research is needed “to investigate these mechanisms that might underlie the association we found between PTSD and cognitive decline,” she said.
 

Neurotoxic effect

In a comment, Howard Fillit, MD, cofounder and chief science officer of the Alzheimer’s Drug Discovery Foundation, said, “It is well known that stress is neurotoxic, and PTSD is a particularly serious form of stress.”

Dr. Fillit, clinical professor of geriatric medicine and palliative care, medicine, and neuroscience at Mount Sinai Hospital, New York, was not involved with the study.

“We tend to think of PTSD in postacute settings, such as soldiers returning from war,” he said. “This study contributes to our understanding of the long-term effects of PTSD on cognitive decline, measured objectively over time”

Dr. Fillit noted that an important implication is that, by increasing the risk for cognitive decline, PTSD also increases risk for Alzheimer’s disease. This leads to the “main take-home, which is that PTSD is a risk factor not only for cognitive decline but also for Alzheimer’s and related dementias,” he said.

However, this opens a potential therapeutic approach, Dr. Fillit added.

Because cortisol and other stress hormones drive the stress response, finding ways to block the neurotoxic effects of these hormones “might be a target to prevent cognitive decline and decrease Alzheimer’s disease risk,” he said.

The study was supported by grants from the National Institute of Mental Health and the National Institutes of Health. Ms. Liu and Dr. Fillit report no relevant financial relationships.

Scientists at Johns Hopkins University have identified a mechanism in the brain behind age-related memory loss, expanding our knowledge of the inner workings of the aging brain and possibly opening the door to new Alzheimer’s treatments.

The researchers looked at the hippocampus, a part of the brain thought to store long-term memories.

Neurons there are responsible for a pair of memory functions – called pattern separation and pattern completion – that work together in young, healthy brains. These functions can swing out of balance with age, impacting memory.

The Johns Hopkins team may have discovered what causes this imbalance. Their findings – reported in a paper in the journal Current Biology – may not only help us improve dementia treatments, but even prevent or delay a loss of thinking skills in the first place, the researchers say.
 

Pattern separation vs. pattern completion

To understand how the hippocampus changes with age, the researchers looked at rats’ brains. In rats and in humans, pattern separation and pattern completion are present, controlled by neurons in the hippocampus.

As the name suggests, pattern completion is when you take a few details or fragments of information – a few notes of music, or the start of a famous movie quote – and your brain retrieves the full memory. Pattern separation, on the other hand, is being able to tell similar observations or experiences apart (like two visits to the same restaurant) to be stored as separate memories.

These functions occur along a gradient across a tiny region called CA3. That gradient, the study found, disappears with aging, said lead study author Hey-Kyoung Lee, PhD, an assistant research scientist at the university’s Zanvyl Krieger Mind/Brain Institute. “The main consequence of the loss,” Dr. Lee said, “is that pattern completion becomes more dominant in rats as they age.”
 

What’s happening in the brain

Neurons responsible for pattern completion occupy the “distal” end of CA3, while those in charge of pattern separation reside at the “proximal” end. Dr. Lee said prior studies had not examined the proximal and distal regions separately, as she and her team did in this study.

What was surprising, said Dr. Lee, “was that hyperactivity in aging was observed toward the proximal CA3 region, not the expected distal region.” Contrary to their expectations, that hyperactivity did not enhance function in that area but rather dampened it. Hence: “There is diminished pattern separation and augmented pattern completion,” she said.

As pattern completion dominates, pattern separation fades, Dr. Lee said. This may make it harder for older adults to separate memories – they may recall a certain restaurant they’d been to but not be able to separate what happened during one visit versus another.
 

Why do some older adults stay sharp?

That memory impairment does not happen to everyone, and it doesn’t happen to all rats either. In fact, the researchers found that some older rats performed spatial-learning tasks as well as young rats did – even though their brains were already beginning to favor pattern completion.

If we can better understand why this happens, we may uncover new therapies for age-related memory loss, Dr. Lee said.

Coauthor Michela Gallagher’s team previously demonstrated that the anti-epilepsy drug levetiracetam improves memory performance by reducing hyperactivity in the hippocampus.

The extra detail this study adds may allow scientists to better aim such drugs in the future, Dr. Lee speculated. “It would give us better control of where we could possibly target the deficits we see.”

There are still misperceptions of palliative medicine, including when to consider referral to a palliative care specialist.

The World Health Organization defines palliative care as “an approach that improves the quality of life of patients (adults and children) and their families who are facing problems associated with life-threatening illness. It prevents and relieves suffering through the early identification, correct assessment, and treatment of pain and other problems, whether physical, psychosocial or spiritual.”¹

The common misperception is that palliative care is only for those at end of life or only in the advanced stages of their illness. However, palliative care is ideally most helpful following individuals from diagnosis through their illness trajectory. Another misperception is that palliative care and hospice are the same thing. Though all hospice is palliative care, all palliative care is not hospice. Both palliative care and hospice provide care for individuals facing a serious illness and focus on the same philosophy of care, but palliative care can be initiated at any stage of illness, even if the goal is to pursue curative and life-prolonging therapies/interventions.

In contrast, hospice is considered for those who are at the end of life and are usually not pursuing life-prolonging therapies or interventions, instead focusing on comfort, symptom management, and optimization of quality of life.

Though there is a growing need for palliative care, there is a shortage of specialist palliative care providers. Much of the palliative care needs can be met by all providers who can offer basic symptom management, identification surrounding goals of care and discussions of advance care planning, and understanding of illness/prognosis and treatment options, which is called primary palliative care.² In fact, two-thirds of patients with a serious illness other than cancer prefer discussion of end-of-life care or advance care planning with their primary care providers.³

Referral to specialty palliative care should be considered when there are more complexities to symptom/pain management and goals of care/end of life, transition to hospice, or complex communication dynamics.⁴

Though specialty palliative care was shown to be more comprehensive, both primary palliative care and specialty palliative care have led to improvements in the quality of life in individuals living with serious illness.⁵ Early integration of palliative care into routine care has been shown to improve symptom burden, mood, quality of life, survival, and health care costs.⁶

Updates in alternative and complementary therapies to palliative care

There are several alternative and complementary therapies to palliative care, including cannabis and psychedelics. These therapies are becoming or may become a familiar part of medical therapies that are listed in a patient’s history as part of their medical regimen, especially as more states continue to legalize and/or decriminalize the use of these alternative therapies for recreational or medicinal use.

Both cannabis and psychedelics have a longstanding history of therapeutic and holistic use. Cannabis has been used to manage symptoms such as pain since the 16th and 17th century.⁷ In palliative care, more patients may turn to various forms of cannabis as a source of relief from symptoms and suffering as their focus shifts more to quality of life.

Even with the increasing popularity of the use of cannabis among seriously ill patients, there is still a lack of evidence of the benefits of medical cannabis use in palliative care, and there is a lack of standardization of type of cannabis used and state regulations regarding their use.⁷

A recent systematic review found that despite the reported positive treatment effects of cannabis in palliative care, the results of the studies were conflicting. This highlights the need for further high-quality research to determine whether cannabis products are an effective treatment in palliative care patients.⁸

One limitation to note is that the majority of the included studies focused on cannabis use in patients with cancer for cancer-related symptoms. Few studies included patients with other serious conditions.
 

Psychedelics

There is evidence that psychedelic assisted therapy (PAT) is a safe and effective treatment for individuals with refractory depression, posttraumatic stress disorder, and substance use disorder.⁹ Plus, there have been ample studies providing support that PAT improves symptoms such as refractory anxiety/depression, demoralization, and existential distress in seriously ill patients, thus improving their quality of life and overall well-being.⁹

Nine U.S. cities and the State of Oregon have decriminalized or legalized the psychedelic psilocybin, based on the medical benefits patients have experienced evidenced from using it.¹⁰

In light of the increasing interest in PAT, Dr. Ira Byock provided the following points on what “all clinicians should know as they enter this uncharted territory”:

• Psychedelics have been around for a long time.
• Psychedelic-assisted therapies’ therapeutic effects are experiential.
• There are a variety of terms for specific categories of psychedelic compounds.
• Some palliative care teams are already caring for patients who undergo psychedelic experiences.
• Use of psychedelics should be well-observed by a skilled clinician with expertise.

I am hoping this provides a general refresher on palliative care and an overview of updates to alternative and complementary therapies for patients living with serious illness.⁹

• Some palliative care teams are already caring for patients who undergo psychedelic experiences.
• Use of psychedelics should be well-observed by a skilled clinician with expertise.

I am hoping this provides a general refresher on palliative care and an overview of updates to alternative and complementary therapies for patients living with serious illness.⁹

Thanks to effective treatment, people with HIV are living longer. But as they age, they face higher rates of age-related comorbidities and hospitalizations, according to a recent study of hospitalized patients.

Decision-makers will need to allocate resources, train providers, and plan ways to manage chronic diseases, such as diabetes and cancer, among geriatric HIV inpatients, according to the authors.

“There will be more [HIV] patients with age-related chronic conditions at an earlier age and who will utilize or will have a unique need for [health care for] these geriatric conditions,” first author Khairul A. Siddiqi, PhD, University of Florida, Gainesville, said in an interview. “Eventually, that may increase inpatient resource utilization and costs.”

The study was published online in HIV Medicine.
 

Aging with HIV

Analyzing the National Inpatient Sample (NIS) of the Healthcare Cost and Utilization Project, the authors compared characteristics and comorbidities linked to hospital stays among people with HIV (HSWH) to those linked to hospital stays among people without HIV (HSWOH).

The NIS is a database of hospital records that captures 20% of discharges in the United States and covers all payers. Data in this analysis covered the years 2003-2015.

Among HSWH, patients aged 50 or older accounted for an increasing proportion over time, from fewer than 25% in 2003 to over 50% by 2015, the authors found. The subgroup aged 65-80 had risen from 2.39% to 8.63% by 2015.

The authors also studied rates of eight comorbidities, termed HIV-associated non-AIDS (HANA) conditions: cardiovascular, lung, liver, neurologic, and kidney diseases; diabetes; cancer; and bone loss.

The average number of these conditions among both HSWH and HSWOH rose over time. But this change was disproportionately high among HSWH aged 50-64 and those aged 65 and older.

Over the study period, among patients aged 65 or older, six of the eight age-related conditions the researchers studied rose disproportionately among HSWH in comparison with HSWOH; among those aged 50-64, five conditions did so.

The researchers are now building on the current study of HSWH by examining rates of resource utilization, such as MRIs and procedures, Dr. Siddiqi said.

Study limitations included a lack of data from long-term facilities, potential skewing by patients hospitalized multiple times, and the inherent limitations of administrative data.
 

A unique group of older people

Among people with HIV (PWH) in the United States, nearly half are aged 50 or older. By 2030, this group is expected to account for some 70% of PWH.

“We need to pay attention to what we know about aging generally. It is also important to study aging in this special population, because we don’t necessarily know a lot about that,” Amy Justice, MD, PhD, professor of medicine and of public health at Yale University, New Haven, Conn., said in an interview. Dr. Justice was not involved in the study.

The HIV epidemic has disproportionately affected people of color, men who have sex with men, and people with a history of injection drug use, Dr. Justice said.

“We don’t know about aging with [a] past history of injection drug use. We don’t even know much about aging with hepatitis C, necessarily,” she said. “So there are lots of reasons to pay some attention to this population to try to optimize their care.”

In addition, compared with their non–HIV-affected counterparts, these individuals are more susceptible to HANA comorbidities. They may experience these conditions at a younger age or more severely. Chronic inflammation and polypharmacy may be to blame, said Dr. Justice.

Given the burden of comorbidities and polypharmacy in this patient population, Dr. Siddiqi said, policy makers will need to focus on developing chronic disease management interventions for them.

However, Dr. Justice added, the risk for multimorbidity is higher among people with HIV throughout the age cycle: “It’s not like I turn 50 with HIV and all of a sudden all the wheels come off. There are ways to successfully age with HIV.”
 

Geriatric HIV expertise needed

Dr. Justice called the study’s analysis a useful addition to the literature and noted its implications for training.

“One of the biggest challenges with this large bolus of folks who are aging with HIV,” she said, “is to what extent should they be cared for by the people who have been caring for them – largely infectious disease docs – and to what extent should we really be transitioning their care to people with more experience with aging.”

Another key question, Dr. Justice said, relates to nursing homes and assisted-living facilities, whose staff may lack experience caring for HIV patients. Training them and hospital-based providers is crucial, in part to avoid key errors, such as missed antiretroviral doses, she said: “We need to really think about how to get non-HIV providers up to speed.”

That may begin by simply making it clear that this population is here.

“A decade ago, HIV patients used to have a lower life expectancy, so all HIV studies used to use 50 years as the cutoff point for [the] older population,” Dr. Siddiqi said. “Now we know they’re living longer.”

Added Dr. Justice: “Previously, people thought aging and HIV were not coincident findings.”

The study was funded by the Office of the Vice President for Research at the University of South Carolina. The authors and Dr. Justice disclosed no relevant financial relationships.

CHARLOTTE, N.C. – Poor objective sleep efficiency may contribute to older adults overestimating their cognitive abilities, preliminary findings from a pilot study of objective and subjective cognitive measures have shown.

The pilot study underscored the important role of objective sleep measures to better understand discrepancies when patients’ own reports of everyday cognitive function don’t align with objective cognitive profiles, Amy Costa, MA, a graduate student in psychology at the University of Missouri-Columbia, said in reporting the results at the annual meeting of the Associated Professional Sleep Societies.

“Between our previously published paper and these new pilot results, we’re reporting evidence that suggests sleep is playing a role between the objective and subjective cognition relationship,” Ms. Costa said in an interview. “It is possible that these older adults who are sleeping poorly may be worse at understanding how well they’re doing cognitively. That’s really important for doctors. For example, if we can’t diagnose someone with mild cognitive impairment or Alzheimer’s disease or other types of dementia earlier, then we can’t intervene as quickly.”
 

Sleep efficiency, cognition, and patient complaints

These findings are in agreement with those Ms. Costa and colleagues recently published in the Journal of Clinical Sleep Medicine, she said.

The current pilot study included 35 older adults with an average age of 69 years who had insomnia complaints. They completed one night of home-based polysomnography – specifically with the Sleep Profiler PSG2TM – and a battery of cognitive tests. Their average sleep deficiency was 57%, “indicating potentially pretty severe insomnia,” Ms. Costa said.

“We found that sleep efficiency – that is the percentage of time spent sleeping while in bed – moderated the association between self reports and objective measures of cognitive distractibility,” Ms. Costa said in reporting the results. “In other words, our findings suggest that individuals with lower sleep efficiency who are performing the worst cognitively have the least amount of complaints. Basically, this can be thought of as that they are overestimating their cognitive performance.”
 

Sleep stage versus working memory and distractibility

The pilot study also focused on how the percentage of lighter-stage sleep, or N1 sleep, moderated the associations between working memory, as measured by Sternberg performance, and memory, distractibility, and blunders measured with the Cognitive Failures Questionnaire.

At the highest percentage of N1 sleep, worse working memory was associated with fewer complaints about memory, distractibility, and blunders, Ms. Costa said.

“The percentage of lighter-stage N1 sleep and sleep efficiency moderated the association between cognitive flexibility and distractibility,” Ms. Costa said.  At the lowest percentage of N1 sleep, worse cognitive flexibility was associated with more distractibility, while at the highest percentage of N1 sleep worse cognitive flexibility showed a reverse effect; it was linked to less distractibility. The lowest percentage of sleep efficiency showed an association between worse cognitive flexibility and less distractibility, but the highest percentage of SE showed an association between worse cognitive flexibility and more distractibility.

“So in terms of evaluating their cognitive performance, the worse working memory was associated with more blunder complaints in individuals with the lowest percentage of N1,” she said. “So whenever individuals were spending less time in N1, they were able to better recognized their cognitive ability.”

She added, “Overall, more light and more fragmented sleep moderated the association between worse objective and less cognitive complaints, suggesting that these individuals might be overestimating their cognitive abilities.”

The findings indicate that evaluation of objective sleep should consider objectively measured N1 and sleep efficiency to better understand when subjective cognitive complaints and neurophysiological/objective cognitive profiles don’t align, she said.
 

Important indicators of cognitive deficits

“Specifically, for an older adult who comes into the clinic with complaints of waking up during the night, low sleep efficiency and more lighter-stage sleep might be really important indicators that they are probably not going to be the best at identifying their cognitive abilities or deficits,” she said.

Future directions for this research include collecting more data and looking at other sleep measures, such as using rapid-eye movement sleep, as potential moderators for the relationship between cognitive outcomes, evaluating sleep architecture more closely, and evaluating outcomes in a longitudinal study, Ms. Costa said.
 

The importance of objectively measured sleep

“Studies like this one using objectively measured sleep are important because much of the prior literature relied on self-reported sleep measures,” said Brendan P. Lucey, MD, associate professor of neurology and head of the sleep medicine section at Washington University School of Medicine in St. Louis. “This study suggests how objectively measured sleep may mediate discrepancies in objective/subjective cognitive dysfunction. Future studies need to work out if we need to add objective sleep measures when evaluating cognitive complaints in older adults.”

Dr. Lucey, who was not involved in the study, voiced one concern with the pilot study methodology the future research should address: the use of the Sleep Profiler PSG2TM to measure N1 sleep, which, as he noted, records a single-channel electroencephalogram over the forehead. “Scoring N1 sleep relies on attenuation of the alpha rhythm over the occipital region and the Sleep Profiler is not as accurate as in-lab polysomnography for this sleep stage,” he said.

The pilot study received funding from the American Academy of Sleep Medicine Foundation. Ms. Costa and her coauthors have no disclosures. Dr. Lucey disclosed relationships with Merck, Eli Lilly, Eisai, and Beacon Biosignals.
