Rural patients with early onset dementia are more likely than urban patients to rely solely on primary care physicians or nurse practitioners for the initial diagnosis and treatment of the disease, a new study has found.

Patients in rural areas are also less likely to see psychologists and undergo neuropsychological testing, according to the study, published in JAMA Network Open.

Patients who forgo such specialist visits and testing may be missing information about their condition that could help them prepare for changes in job responsibilities and future care decisions, said Wendy Yi Xu, PhD, of The Ohio State University, Columbus, who led the research.

“A lot of them are still in the workforce,” Dr. Xu said. Patients in the study were an average age of 56 years, well before the conventional age of retirement.
 

Location, location, location

To examine rural versus urban differences in the use of diagnostic tests and health care visits for early onset Alzheimer’s disease and related dementias, Dr. Xu and colleagues analyzed commercial claims data from 2012-2018. They identified more than 71,000 patients aged 40-64 years with those conditions and focused on health care use by 7,311 patients in urban areas and 1,119 in rural areas within 90 days of a new dementia diagnosis.

The proportion who received neuropsychological testing was 19% among urban patients and 16% among rural patients. Psychological assessments, which are less specialized and detailed than neuropsychological testing, and brain imaging occurred at similar rates in both groups. Similar proportions of rural and urban patients visited neurologists (17.7% and 17.96%, respectively) and psychiatrists (6.02% and 6.47%).

But more urban patients than rural patients visited a psychologist, at 19% versus 15%, according to the researchers.

Approximately 18% of patients in rural areas saw a primary care provider without visiting other specialists, compared with 13% in urban areas.

The researchers found that rural patients were significantly less likely to undergo neuropsychological testing (odds ratio, 0.83; 95% confidence interval, 0.70-0.98) or see a psychologist (OR, 0.72; 95% CI, 0.60-0.85).

Similarly, rural patients had significantly higher odds of having only primary care providers involved in the diagnosis of dementia and symptom management (OR, 1.40; 95% CI, 1.19-1.66).
 

Addressing workforce deficiencies

More primary care training in dementia care and collaboration with specialist colleagues could help address differences in care, Dr. Xu’s group writes. Such efforts are already underway.

In 2018, the Alzheimer’s Association launched telementoring programs focused on dementia care using the Project ECHO (Extension for Community Healthcare Outcomes) model. Researchers originally developed Project ECHO at the University of New Mexico in 2003 to teach primary care clinicians in remote settings how to treat patients infected with the hepatitis C virus.

With the Alzheimer’s and Dementia Care ECHO Program for Clinicians, primary care clinicians can participate in interactive case-based video conferencing sessions to better understand dementia and how to provide high-quality care in community settings, according to the association.

The program covers guidelines for diagnosis, disclosure, and follow-up; the initiation of care planning; managing disease-related challenges; and resources for patients and caregivers.

Since 2018, nearly 100 primary care practices in the United States have completed training in dementia care using Project ECHO, said Morgan Daven, vice president of health systems for the Alzheimer’s Association. Many cases featured in the program are challenging, he added.

“With primary care being on the front lines, it is really important that primary care physicians are equipped to do what they can to detect or diagnose and know when to refer,” Mr. Daven said.

The association has compiled other resources for clinicians as well.

A 2020 report from the association examined the role that primary care physicians play in dementia care. One survey found that 82% of primary care physicians consider themselves on the front lines of providing care for patients with dementia.

Meanwhile, about half say medical professionals are not prepared to meet rising demands associated with Alzheimer’s disease and dementia care.

Mr. Daven said the geographic disparities Dr. Xu and colleagues found are unsurprising. More than half of primary care physicians who care for people with Alzheimer’s disease say dementia specialists in their communities cannot meet demand. The problem is more urgent in rural areas. Roughly half of nonmetropolitan counties in the United States lack a practicing psychologist, according to a 2018 study published in the American Journal of Preventive Medicine.

“We really need to approach this on both sides – build the capacity in primary care, but we also need to address the dementia care specialty shortages,” Mr. Daven said.

The lack of obvious differences in access to neurologists in the new study “was surprising, given the more than fourfold difference between urban and rural areas in the supply of neurologists,” the researchers note. Health plans may maintain more access to neurologists than psychologists because of relatively higher reimbursement for neurologists, they observed.

One of the study coauthors disclosed ties to Aveanna Healthcare, a company that delivers home health and hospice care.

Every day, we depend on our working memory, spatial cognition, and processing speed abilities to optimize productivity, interpersonal interactions, and psychological wellbeing. These cognitive functioning indices relate closely with academic and work performance, managing emotions, physical fitness, and a sense of fulfillment in personal and work relationships. They are linked intimately to complex cognitive skills (van Dijk et al., 2020). It is thus imperative to identify modifiable predictors of cognitive functioning in the brain to protect against aging-related cognitive decline and maximize the quality of life.

Enhancing life satisfaction is a possible way to enhance working memory, spatial cognition, and processing speed or protect against their decline. A decline in life satisfaction can worsen cognitive functioning over long periods via lifestyle factors (e.g., suboptimal diet and nutrition, lack of exercise) (Ratigan et al., 2016). Inadequate engagement in these health-enhancing pursuits could build up inflammation in EF-linked brain areas, thus negatively impacting cognitive functioning in adulthood (Grant et al., 2009). Possible pathways include long-term wear and tear of the hypothalamic-pituitary axis and brain regions linked to executive functioning (Zainal and Newman, 2022a). These processes may deteriorate working memory, spatial cognition, and processing speed across time.

Similarly, it is plausible that a reduction in cognitive functioning may lead to a long-term decrease in life satisfaction. Working memory, processing speed, spatial cognition, and related capacities are essential to meaningful activities and feelings of gratification in personal and professional relationships and other spheres of health throughout life (Baumeister et al., 2007). These cognitive functioning markers safeguard against reduced life satisfaction by facilitating effective problem-solving, and choices (Swanson and Fung, 2016). For example, stronger working memory, processing speed, and related domains coincided with better tolerance for stress and trading off immediate rewards for long-term values and life goals (Hofmann et al., 2012). Therefore, reduction in cognitive functioning abilities could precede a future decline in life satisfaction.

Nonetheless, the literature on this topic has several limitations. Most of the studies have been cross-sectional (i.e., across a single time-point) and thus do not permit inferences between cause and effect (e.g., Toh et al., 2020). Also, most studies used statistical methods that did not differentiate between between-person (trait-like individual differences) and within-person (state-like) relations. Distinguishing within- and between-person relations is necessary because they may vary in magnitude and direction. The preceding theories emphasize change-to-future change relations within persons rather than between persons (Wright and Woods, 2020).
 

Clinical implications

Our recent work (Zainal and Newman, 2022b) added to the literature by using an advanced statistical method to determine the relations between change in life satisfaction and future change in cognitive functioning domains within persons. The choice of an advanced statistical technique minimizes biases due to the passage of time and assessment unreliability. It also adjusts for between-person effects (Klopack and Wickrama, 2020). Improving understanding of the within-person factors leading to the deterioration of cognitive functioning and life satisfaction is crucial given the rising rates of psychiatric and neurocognitive illnesses (Cui et al., 2020). Identifying these changeable risk factors can optimize prevention, early detection, and treatment approaches.

Specifically, we analyzed the publicly available Swedish Adoption/Twin Study of Aging (SATSA) dataset (Petkus et al., 2017). Their dataset comprised 520 middle- to older-aged twin adults without dementia. Participants provided data across 23 years with five time points. Each time lag ranged from 3 to 11 years. The analyses demonstrated that greater decreases in life satisfaction predicted larger future declines in processing speed, verbal working memory, and spatial cognition. Moreover, declines in verbal working memory and processing speed predicted a reduction in life satisfaction. However, change in spatial awareness did not predict change in life satisfaction.

Our study offers multiple theoretical perspectives. Scar theories propose that decreased life satisfaction and related mental health problems can compromise working memory, processing speed, and spatial cognition in the long term. This scarring process occurs through the buildup of allostatic load, such as increased biomarkers of chronic stress (e.g., cortisol) and inflammation (e.g., interleukin-6, C-reactive protein) (Fancourt and Steptoe, 2020; Zainal and Newman, 2021a). Also, findings suggest the importance of executive functioning domains to attain desired milestones and aspirations to enhance a sense of fulfillment (Baddeley, 2013; Toh and Yang, 2020). Reductions in these cognitive functioning capacities could, over time, adversely affect the ability to engage in daily living activities and manage negative moods.

Limitations of our study include the lack of a multiple-assessment approach to measuring diverse cognitive functioning domains. Also, the absence of cognitive self-reports is a shortcoming since perceived cognitive difficulties might not align with performance on cognitive tests. Relatedly, future studies should administer cognitive tests that parallel and transfer to everyday tasks. However, our study’s strengths include the robust findings across different intervals between study waves, advanced statistics, and the large sample size.

If future studies replicate a similar pattern of results, the clinical applications of this study merit attention. Mindfulness-based interventions can promote working memory, sustained awareness, and spatial cognition or protect against cognitive decline (Jha et al., 2019; Zainal and Newman, 2021b). Further, clinical science can profit from exploring cognitive-behavioral therapies to improve adults’ cognitive function or life satisfaction (Sok et al., 2021).

Every day, we depend on our working memory, spatial cognition, and processing speed abilities to optimize productivity, interpersonal interactions, and psychological wellbeing. These cognitive functioning indices relate closely with academic and work performance, managing emotions, physical fitness, and a sense of fulfillment in personal and work relationships. They are linked intimately to complex cognitive skills (van Dijk et al., 2020). It is thus imperative to identify modifiable predictors of cognitive functioning in the brain to protect against aging-related cognitive decline and maximize the quality of life.

Enhancing life satisfaction is a possible way to enhance working memory, spatial cognition, and processing speed or protect against their decline. A decline in life satisfaction can worsen cognitive functioning over long periods via lifestyle factors (e.g., suboptimal diet and nutrition, lack of exercise) (Ratigan et al., 2016). Inadequate engagement in these health-enhancing pursuits could build up inflammation in EF-linked brain areas, thus negatively impacting cognitive functioning in adulthood (Grant et al., 2009). Possible pathways include long-term wear and tear of the hypothalamic-pituitary axis and brain regions linked to executive functioning (Zainal and Newman, 2022a). These processes may deteriorate working memory, spatial cognition, and processing speed across time.

Similarly, it is plausible that a reduction in cognitive functioning may lead to a long-term decrease in life satisfaction. Working memory, processing speed, spatial cognition, and related capacities are essential to meaningful activities and feelings of gratification in personal and professional relationships and other spheres of health throughout life (Baumeister et al., 2007). These cognitive functioning markers safeguard against reduced life satisfaction by facilitating effective problem-solving, and choices (Swanson and Fung, 2016). For example, stronger working memory, processing speed, and related domains coincided with better tolerance for stress and trading off immediate rewards for long-term values and life goals (Hofmann et al., 2012). Therefore, reduction in cognitive functioning abilities could precede a future decline in life satisfaction.

Nonetheless, the literature on this topic has several limitations. Most of the studies have been cross-sectional (i.e., across a single time-point) and thus do not permit inferences between cause and effect (e.g., Toh et al., 2020). Also, most studies used statistical methods that did not differentiate between between-person (trait-like individual differences) and within-person (state-like) relations. Distinguishing within- and between-person relations is necessary because they may vary in magnitude and direction. The preceding theories emphasize change-to-future change relations within persons rather than between persons (Wright and Woods, 2020).
 

Clinical implications

Our recent work (Zainal and Newman, 2022b) added to the literature by using an advanced statistical method to determine the relations between change in life satisfaction and future change in cognitive functioning domains within persons. The choice of an advanced statistical technique minimizes biases due to the passage of time and assessment unreliability. It also adjusts for between-person effects (Klopack and Wickrama, 2020). Improving understanding of the within-person factors leading to the deterioration of cognitive functioning and life satisfaction is crucial given the rising rates of psychiatric and neurocognitive illnesses (Cui et al., 2020). Identifying these changeable risk factors can optimize prevention, early detection, and treatment approaches.

Specifically, we analyzed the publicly available Swedish Adoption/Twin Study of Aging (SATSA) dataset (Petkus et al., 2017). Their dataset comprised 520 middle- to older-aged twin adults without dementia. Participants provided data across 23 years with five time points. Each time lag ranged from 3 to 11 years. The analyses demonstrated that greater decreases in life satisfaction predicted larger future declines in processing speed, verbal working memory, and spatial cognition. Moreover, declines in verbal working memory and processing speed predicted a reduction in life satisfaction. However, change in spatial awareness did not predict change in life satisfaction.

Our study offers multiple theoretical perspectives. Scar theories propose that decreased life satisfaction and related mental health problems can compromise working memory, processing speed, and spatial cognition in the long term. This scarring process occurs through the buildup of allostatic load, such as increased biomarkers of chronic stress (e.g., cortisol) and inflammation (e.g., interleukin-6, C-reactive protein) (Fancourt and Steptoe, 2020; Zainal and Newman, 2021a). Also, findings suggest the importance of executive functioning domains to attain desired milestones and aspirations to enhance a sense of fulfillment (Baddeley, 2013; Toh and Yang, 2020). Reductions in these cognitive functioning capacities could, over time, adversely affect the ability to engage in daily living activities and manage negative moods.

Limitations of our study include the lack of a multiple-assessment approach to measuring diverse cognitive functioning domains. Also, the absence of cognitive self-reports is a shortcoming since perceived cognitive difficulties might not align with performance on cognitive tests. Relatedly, future studies should administer cognitive tests that parallel and transfer to everyday tasks. However, our study’s strengths include the robust findings across different intervals between study waves, advanced statistics, and the large sample size.

If future studies replicate a similar pattern of results, the clinical applications of this study merit attention. Mindfulness-based interventions can promote working memory, sustained awareness, and spatial cognition or protect against cognitive decline (Jha et al., 2019; Zainal and Newman, 2021b). Further, clinical science can profit from exploring cognitive-behavioral therapies to improve adults’ cognitive function or life satisfaction (Sok et al., 2021).

More than 60% of Americans older than age 50, and nearly 70% of those older than 65, say they intend to roll up their sleeves to prevent COVID-19 in the fall of 2022.

That finding comes from a new poll by researchers at the University of Michigan, Ann Arbor, who also report that when it comes to the shots, people appear to be putting more trust in their health care professionals than in public health authorities.

“When you are a doctor, you are a trusted source of medical information,” said Preeti Malani, MD, MSJ, an infectious disease specialist at the University of Michigan. “Use the ongoing conversation with your patient as an opportunity to answer their questions and counter any confusion.”

The vaccination campaign appears to be having a rub-off effect, too. More people say they’re likely to receive vaccines and boosters for other infections, such as flu, if they have already been vaccinated and boosted against COVID-19.
 

Inside the poll

Dr. Malani and her colleagues, who published their findings on the National Poll on Healthy Aging’s website, asked 1,024 adults older than 50 about their attitudes on COVID-19 vaccinations and their history of receiving the injections. The questions covered topics including whether the individual had contracted COVID, COVID vaccine doses, and the prevalence of a health care clinician’s opinion on vaccines and boosters. The poll was conducted July 21-26.

The researchers chose the age range of 50-65 years because this group is an important population for new booster shots that target specific variants of the SARS-CoV-2 virus that causes COVID-19.

Only 19% of people aged 50-64 and 44% of those older than 65 said they had received both their first and second COVID-19 booster shots. What’s more, 17% of people said they had not received any doses of a COVID-19 vaccine.

The vast majority (77%) of respondents said their clinician’s recommendations were “very important” or “somewhat important” in their decision to receive the vaccine. 

Dr. Malani said that in her practice, patients have expressed hesitation about COVID-19 vaccines because of concerns about the potential side effects of the shots.

Monica Gandhi, MD, MPH, professor of medicine at the University of California, San Francisco, noted that Americans now appear to trust their physicians more than public health authorities such as the U.S. Centers for Disease Control and Prevention when it comes to COVID-19.

“More people are trusting their providers’ opinions [more] than the CDC or other public health agencies. That speaks volumes to me,” Dr. Gandhi said.

Among the more surprising findings of the poll, according to the researchers, was the number of people who said they had yet to contract COVID-19: 50% of those aged 50-64, and 69% of those older than 65. (Another 12% of those aged 50-64 said they were unsure if they’d ever had the infection.)

Dr. Malani said she hoped future studies would explore in depth the people who remain uninfected with COVID-19.

“We focus a lot on the science of COVID,” she said. “But we need to turn our attention to the behavioral aspects and how to address them.”

A new study sheds light on the neurologic underpinnings of late-life depression (LLD) with apathy and its frequently poor response to treatment.

Investigators headed by Faith Gunning, PhD, of the Institute of Geriatric Psychiatry, Weill Cornell Medicine, New York, analyzed baseline and posttreatment brain MRIs and functional MRIs (fMRIs) of older adults with depression who participated in a 12-week open-label nonrandomized clinical trial of escitalopram. Participants had undergone clinical and cognitive assessments.

Disturbances were found in resting state functional connectivity (rsFC) between the salience network (SN) and other large-scale networks that support goal-directed behavior, especially in patients with depression who also had features of apathy.

Even after participants had completed escitalopram treatment, apathy-related variability in functional connectivity was associated with poor antidepressant response and persistent cognitive dysfunction.

“This study suggests that, among older adults with depression, distinct network abnormalities may be associated with apathy and poor response to first-line pharmacotherapy and may serve as promising targets for novel interventions,” the investigators write.

The study was published online in JAMA Network Open.
 

A leading cause of disability

LLD is a “leading cause of disability and medical morbidity in older adulthood,” with one-third to one-half of patients with LLD also suffering from apathy, the authors write.

Older adults with depression and comorbid apathy have poorer outcomes, including lower remission rates and poorer response to first-line antidepressants, compared with those with LLD but who do not have apathy.

Despite the high prevalence of apathy in people with depression, “little is known about its optimal treatment and, more broadly, about the brain-based mechanisms of apathy,” the authors note.

An “emerging hypothesis” points to the role of a compromised SN and its large-scale connections between apathy and poor treatment response in LLD.

The SN (which includes the insula and the dorsal anterior cingulate cortex) “attributes motivational value to a stimulus” and “dynamically coordinates the activity of other large-scale networks, including the executive control network and default mode network (DMN).”

Preliminary studies of apathy in patients with depression report reduced volume in structures of the SN and suggest disruption in functional connectivity among the SN, DMN, and the executive control network; but the mechanisms linking apathy to poor antidepressant response in LLD “are not well understood.”

“Connectometry” is a “novel approach to diffusion MRI analysis that quantifies the local connectome of white matter pathways.” It has been used along with resting-state imagery, but it had not been used in studying apathy.

The researchers investigated the functional connectivity of the SN, hypothesizing that alterations in connectivity among key nodes of the SN and other core circuits that modulate goal-directed behavior (DMN and the executive control network) were implicated in individuals with depression and apathy.

They applied connectometry to “identify pathway-level disruptions in structural connectivity,” hypothesizing that compromise of frontoparietal and frontolimbic pathways would be associated with apathy in patients with LLD.

They also wanted to know whether apathy-related network abnormalities were associated with antidepressant response after 12 weeks of pharmacotherapy with the selective serotonin reuptake inhibitor escitalopram.
 

Emerging model

The study included 40 older adults (65% women; mean [SD] age, 70.0 [6.6] years) with DSM-IV–diagnosis major depressive disorder (without psychotic features) who were from a single-group, open-label escitalopram treatment trial.

The Hamilton-Depression (HAM-D) scale was used to assess depression, while the Apathy Evaluation Scale was used to assess apathy. On the Apathy Evaluation Scale, a score of greater than 40.5 represents “clinically significant apathy.” Participants completed these tests at baseline and after 12 weeks of escitalopram treatment.

They also completed a battery of neuropsychological tests to assess cognition and underwent MRI imaging. fMRI was used to map group differences in rsFC of the SN, and diffusion connectometry was used to “evaluate pathway-level disruptions in structural connectivity.”

Of the participants, 20 had clinically significant apathy. There were no differences in age, sex, educational level, or the severity of depression at baseline between those who did and those who did not have apathy.

Compared with participants with depression but not apathy, those with depression and comorbid apathy had lower rsFC of salience network seeds (specifically, the dorsolateral prefrontal cortex [DLPFC], premotor cortex, midcingulate cortex, and paracentral lobule).

They also had greater rsFC in the lateral temporal cortex and temporal pole (z > 2.7; Bonferroni-corrected threshold of P < .0125).

Additionally, participants with apathy had lower structural connectivity in the splenium, cingulum, and fronto-occipital fasciculus, compared with those without apathy (t > 2.5; false discovery rate–corrected P = .02).

Of the 27 participants who completed escitalopram treatment; 16 (59%) achieved remission (defined as an HAM-D score <10). Participants with apathy had poorer response to escitalopram treatment.

Lower insula-DLPFC/midcingulate cortex rsFC was associated with less improvement in depressive symptoms (HAM-D percentage change, beta [df] = .588 [26]; P = .001) as well as a greater likelihood that the participant would not achieve remission after treatment (odds ratio, 1.041; 95% confidence interval, 1.003-1.081; P = .04).

In regression models, lower insula-DLPFC/midcingulate cortex rsFC was found to be a mediator of the association between baseline apathy and persistence of depression.

The SN findings were also relevant to cognition. Lower dorsal anterior cingulate-DLPFC/paracentral rsFC was found to be associated with residual cognitive difficulties on measures of attention and executive function (beta [df] = .445 [26] and beta [df] = .384 [26], respectively; for each, P = .04).

“These findings support an emerging model of apathy, which proposes that apathy may arise from dysfunctional interactions among core networks (that is, SN, DMN, and executive control) that support motivated behavior,” the investigators write.

“This may cause a failure of network integration, leading to difficulties with salience processing, action planning, and behavioral initiation that manifests clinically as apathy,” they conclude.

One limitation they note was the lack of longitudinal follow-up after acute treatment and a “relatively limited neuropsychological battery.” Therefore, they could not “establish the persistence of treatment differences nor the specificity of cognitive associations.”

The investigators add that “novel interventions that modulate interactions among affected circuits may help to improve clinical outcomes in this distinct subgroup of older adults with depression, for whom few effective treatments exist.”

Commenting on the study, Helen Lavretsy, MD, professor of psychiatry in residence and director of the Late-Life Mood, Stress, and Wellness Research Program and the Integrative Psychiatry Clinic, Jane and Terry Semel Institute for Neuroscience and Human Behavior, University of California, Los Angeles, said, the findings “can be used in future studies targeting apathy and the underlying neural mechanisms of brain connectivity.” Dr. Lavretsy was not involved with the study.

A new study sheds light on the neurologic underpinnings of late-life depression (LLD) with apathy and its frequently poor response to treatment.

Investigators headed by Faith Gunning, PhD, of the Institute of Geriatric Psychiatry, Weill Cornell Medicine, New York, analyzed baseline and posttreatment brain MRIs and functional MRIs (fMRIs) of older adults with depression who participated in a 12-week open-label nonrandomized clinical trial of escitalopram. Participants had undergone clinical and cognitive assessments.

Disturbances were found in resting state functional connectivity (rsFC) between the salience network (SN) and other large-scale networks that support goal-directed behavior, especially in patients with depression who also had features of apathy.

Even after participants had completed escitalopram treatment, apathy-related variability in functional connectivity was associated with poor antidepressant response and persistent cognitive dysfunction.

“This study suggests that, among older adults with depression, distinct network abnormalities may be associated with apathy and poor response to first-line pharmacotherapy and may serve as promising targets for novel interventions,” the investigators write.

The study was published online in JAMA Network Open.
 

A leading cause of disability

LLD is a “leading cause of disability and medical morbidity in older adulthood,” with one-third to one-half of patients with LLD also suffering from apathy, the authors write.

Older adults with depression and comorbid apathy have poorer outcomes, including lower remission rates and poorer response to first-line antidepressants, compared with those with LLD but who do not have apathy.

Despite the high prevalence of apathy in people with depression, “little is known about its optimal treatment and, more broadly, about the brain-based mechanisms of apathy,” the authors note.

An “emerging hypothesis” points to the role of a compromised SN and its large-scale connections between apathy and poor treatment response in LLD.

The SN (which includes the insula and the dorsal anterior cingulate cortex) “attributes motivational value to a stimulus” and “dynamically coordinates the activity of other large-scale networks, including the executive control network and default mode network (DMN).”

Preliminary studies of apathy in patients with depression report reduced volume in structures of the SN and suggest disruption in functional connectivity among the SN, DMN, and the executive control network; but the mechanisms linking apathy to poor antidepressant response in LLD “are not well understood.”

“Connectometry” is a “novel approach to diffusion MRI analysis that quantifies the local connectome of white matter pathways.” It has been used along with resting-state imagery, but it had not been used in studying apathy.

The researchers investigated the functional connectivity of the SN, hypothesizing that alterations in connectivity among key nodes of the SN and other core circuits that modulate goal-directed behavior (DMN and the executive control network) were implicated in individuals with depression and apathy.

They applied connectometry to “identify pathway-level disruptions in structural connectivity,” hypothesizing that compromise of frontoparietal and frontolimbic pathways would be associated with apathy in patients with LLD.

They also wanted to know whether apathy-related network abnormalities were associated with antidepressant response after 12 weeks of pharmacotherapy with the selective serotonin reuptake inhibitor escitalopram.
 

Emerging model

The study included 40 older adults (65% women; mean [SD] age, 70.0 [6.6] years) with DSM-IV–diagnosis major depressive disorder (without psychotic features) who were from a single-group, open-label escitalopram treatment trial.

The Hamilton-Depression (HAM-D) scale was used to assess depression, while the Apathy Evaluation Scale was used to assess apathy. On the Apathy Evaluation Scale, a score of greater than 40.5 represents “clinically significant apathy.” Participants completed these tests at baseline and after 12 weeks of escitalopram treatment.

They also completed a battery of neuropsychological tests to assess cognition and underwent MRI imaging. fMRI was used to map group differences in rsFC of the SN, and diffusion connectometry was used to “evaluate pathway-level disruptions in structural connectivity.”

Of the participants, 20 had clinically significant apathy. There were no differences in age, sex, educational level, or the severity of depression at baseline between those who did and those who did not have apathy.

Compared with participants with depression but not apathy, those with depression and comorbid apathy had lower rsFC of salience network seeds (specifically, the dorsolateral prefrontal cortex [DLPFC], premotor cortex, midcingulate cortex, and paracentral lobule).

They also had greater rsFC in the lateral temporal cortex and temporal pole (z > 2.7; Bonferroni-corrected threshold of P < .0125).

Additionally, participants with apathy had lower structural connectivity in the splenium, cingulum, and fronto-occipital fasciculus, compared with those without apathy (t > 2.5; false discovery rate–corrected P = .02).

Of the 27 participants who completed escitalopram treatment; 16 (59%) achieved remission (defined as an HAM-D score <10). Participants with apathy had poorer response to escitalopram treatment.

Lower insula-DLPFC/midcingulate cortex rsFC was associated with less improvement in depressive symptoms (HAM-D percentage change, beta [df] = .588 [26]; P = .001) as well as a greater likelihood that the participant would not achieve remission after treatment (odds ratio, 1.041; 95% confidence interval, 1.003-1.081; P = .04).

In regression models, lower insula-DLPFC/midcingulate cortex rsFC was found to be a mediator of the association between baseline apathy and persistence of depression.

The SN findings were also relevant to cognition. Lower dorsal anterior cingulate-DLPFC/paracentral rsFC was found to be associated with residual cognitive difficulties on measures of attention and executive function (beta [df] = .445 [26] and beta [df] = .384 [26], respectively; for each, P = .04).

“These findings support an emerging model of apathy, which proposes that apathy may arise from dysfunctional interactions among core networks (that is, SN, DMN, and executive control) that support motivated behavior,” the investigators write.

It is generally understood that racism, whether structural or personal, harms the well-being of the individual who experiences it. It has harmful health effects, and it contributes to ethnic inequality. New evidence shows that the experience of racism is associated with worse cognitive function in later life.

That was the fundamental message behind two studies presented at a press conference at the Alzheimer’s Association International Conference.

“We know that there are communities like black African Americans and Hispanic Latinos who are at greater risk for developing Alzheimer’s or another dementia,” said Carl Hill, PhD, who served as a moderator during the press conference. He pointed out that the genetic and lifestyle factors linked to dementia tell only part of the story. “It’s important that the science also examines the unique experiences of those at greater risk for dementia in our society,” said Dr. Hill, who is Alzheimer’s Association Chief Diversity Equity and Inclusion Officer.
 

Racism, memory, and cognition in middle-aged patients

Jennifer J. Manly, PhD, professor of neuropsychology at Columbia University, New York, presented a study of experience of racism and memory scores among a highly diverse, middle-aged cohort.

“There’s little understanding of how the multiple levels of racism – including intrapersonal, institutional, and structural racism – influence cognitive aging and dementia risk,” Dr. Manly said during the press conference.

Among 1,095 participants, 19.5% were non-Latinx White (61% female, mean age 57), 26.0% were non-Latinx Black (63% female, mean age 56), 32.3% were English-speaking Latinx (66% female, mean age 50), and 21.2% were Spanish-speaking Latinx (68% female, mean age 58).

The researchers used the Everyday Discrimination (ED) scale to measure experience of individual racism, the Major Discrimination (MD) scale to measure experience of institutional racism, and residential segregation of the census block group for an individual’s parents to measure residential segregation. Outcome measures included the Digit Span to assess attention and working memory, and the Selective Reminding Test to assess episodic memory.

The study found a clear association between racism and cognition. “The association of interpersonal racism to memory corresponds to 3 years of chronological age, and was driven by non-Hispanic black participants. Next, there was a reliable relationship between institutional racism and memory scores among non-Hispanic black participants, such that each reported civil rights violation corresponded to the effect of about 4.5 years of age on memory,” said Dr. Manly.

“The bottom line is that our results suggest that exposure to racism is a substantial driver of later life memory function, even in middle age, and especially for Black people,” Dr. Manly added.

The results should alert physicians to the complexities of racism and its impact. “Health providers need to be aware that many accumulated risks are historical and structural, and not controlled by the individual. Maybe more importantly, the medical system itself may perpetuate discriminatory experiences that contribute to worse health,” said Dr. Manly.
 

Latinx concerns

Also at the press conference, Adriana Perez, PhD, emphasized the challenges that Spanish-speaking Latinxs have with health care. Just 5%-7% of nurses are Latinx. “The same could be said for physicians, for clinical psychologists ... as you look at the really critical positions to address brain health equity, we are not represented there,” said Dr. Perez, an assistant professor and senior fellow at the University of Pennsylvania School of Nursing in Philadelphia.

She also pointed out that Latinx representation in clinical trials is very low, even though surveys performed by the Alzheimer’s Association show that this population values medical science and is willing to participate. In fact, 85% said they would participate if invited. The trouble is that many clinical trial announcements state that participants must speak English. Even the many Latinos who are bilingual may be put off by that wording: “That is a message that you’re not invited. That’s how it’s perceived,” said Dr. Perez.
 

Racism and cognition in the elderly

At the press conference, Kristen George, PhD, presented results from a study of individuals over age 90. “Racial disparities in dementia have been well characterized, particularly among those people who are aged 65 and older, but we don’t know very much about the oldest old individuals who are aged 90 and older. This group is one of the fastest growing segments of the population, and it’s becoming increasingly diverse,” said Dr. George, assistant professor of epidemiology at the University of California, Davis.

The group enrolled 445 Asian, Black, Latinx, White, and multiracial individuals who were members of Kaiser Permanente Northern California, with a mean age of 92.7 years. They used the Major Experiences of Discrimination Scale to assess discrimination.

The researchers divided them into three groups based on gender, race, and responses to the 10-item scale. Class 1 included largely White men who had reported workplace discrimination, with an average of two major discrimination experiences. Class 2 was made up of White women and non-Whites who reported little or no discrimination, with an average of 0 experiences. Class 3 included all non-White participants, and they reported a mean of four discrimination experiences.

Using class 2 as a reference, executive function was better among class 1 individuals (beta = 0.28; 95% CI, 0.03-0.52) but there was no significant difference between class 3 and class 2. Class 1 had better baseline semantic memory than class 2 (beta = 0.33; 95% CI, 0.07-0.58), and those in class 3 performed significantly worse than class 2 (beta = –0.24; 95% CI, –0.48 to –0.00). There were no between-group differences in baseline verbal or episodic memory.

A close relative was recently diagnosed with follicular lymphoma. He was cared for at a high-ranked cancer center by physicians with demonstrated expertise, and even had the support of a care navigator. Still, he was often left feeling overwhelmed and confused, holding an inch-thick stack of papers, instructions, and pamphlets. As he left his treatment planning visit, reeling from the emotional burden of his diagnosis and all the unfamiliar terminology, he didn’t know what to do or what to expect. Later, when he experienced early signs of tumor lysis syndrome, he struggled to reach his care team for triage and guidance. When he went to the emergency room, his oncologist was never informed.

This scenario is unfortunately common, and versions of this scenario play out thousands of times each day across the US health system. Within the clinic and hospital setting, patients receive excellent care from their providers, but a disconnect emerges once the patient leaves these medical settings: patients at home struggle to find guidance and support, while care teams lack the tools to engage patients between visits or monitor their health across care settings, providers, or episodes of care.

Leveraging Technology to Move From Episodes of Care to Complex Care Journeys

The use of automated messaging, artificial intelligence and natural language processing–driven chat experiences, and text-based support is becoming more common. However, health care lags behind other industries in the adoption of these technologies.^1,2 The slow pace can be warranted, given that health care is more complicated and higher risk than inquiring about a lost package, ordering groceries, or applying for a mortgage. At the same time, many of the consumer engagement tools used to guide an applicant through the multiple steps and complexities of their home loan process or to prompt viewers to select new shows to binge have applications in health care.

Over the past few years, technologies have emerged that guide patients through complex care journeys and allow care teams to monitor and engage patients between visits. These solutions come in different formats, but generally patients can receive messages on their phones that contain disease-specific educational content, prompts to fill prescriptions and take medications, and reminders and guidance on how to prepare for appointments and procedures. These programs also collect relevant data from patients through survey and electronic patient-reported outcomes instruments, as well as connected patient monitoring devices, that help track patient progress and identify issues as they arise. Many programs also incorporate symptom triage pathways and use natural language processing to respond automatically to patient questions and concerns.^3,4

These technology solutions can automate many tasks that in the past required a care team member to spend hours on the phone. Newly freed from such repetitive tasks, care teams can now focus on more in-depth interactions with those patients who are most in need—the types of interactions that are more satisfying and rewarding. Such assistance is particularly needed today with the staffing shortages faced by most health systems.⁵

In addition, technology allows teams to see the panel of patients they are caring for and to quickly identify and take action on any specific needs or issues. Care teams can focus on any patient and see where they are in their journey. When appropriate, some solutions also allow care teams to engage directly with patients through text-messaging, creating a seamless experience and unified communication channel. Ideally, these solutions should be linked or embedded within the electronic health record or other primary system of record, so that teams can easily access these tools through their existing workflows and avoid creating yet another interface to navigate.

The Impact of Low-Tech Solutions to Deliver High-Touch Support

There is evidence showing that digital patient navigation tools impact patient care. In the oncology setting, patients with a digital navigator have achieved over 95% adherence rates with complex oral chemotherapy regimens (Memora Health Unpublished Data. 2022.). In the postpartum setting, a text message–based program improved screening rates for postpartum depression and did so with very high patient satisfaction ratings.⁶ Particularly notable is the fact that this depression screening program achieved these results in a population that was predominantly low income, with more than half belonging to underrepresented minority populations.⁶

We believe these digital patient navigation technologies, specifically low-tech solutions that don’t require app downloads, portal log-ins, or high-speed internet, will transform care delivery over the next 5 to 10 years. Successful management of complex conditions like diabetes or cancer requires more than 3 hours of care each day,⁷ yet most patients spend only 1 or 2 hours per month directly interacting with their health care providers. However, most patients carry their phones with them at all times, and artificial intelligence–enabled text support is “always on” to provide support, monitoring, and guidance, wherever a patient happens to be when assistance is needed.

Shifting the Model to Support a Lifetime of Care

While still in the early stages of development, these tools have the potential to radically alter the practice of medicine, shifting the focus from episodic interactions to continuous journey-based care delivery. Outside of an acute event bringing a patient into the clinic or emergency room, many patients go a year or more without seeing their primary care providers.⁸ During that time, an immense amount of information is underreported or completely lost. Capturing this information in real-time and more holistically over a person’s lifetime of care could provide physicians better insight to both better manage and more fully evaluate the success of treatment plans by tracking patient symptoms, pain, and functional status over time. With this more longitudinal view of the patient, we see a pathway towards achieving the Quadruple Aim: patients who are more supported will achieve better outcomes at lower cost, they will have a better experience, and care teams will be empowered to focus their time on more satisfying activities rather than repetitive administrative tasks.

A close relative was recently diagnosed with follicular lymphoma. He was cared for at a high-ranked cancer center by physicians with demonstrated expertise, and even had the support of a care navigator. Still, he was often left feeling overwhelmed and confused, holding an inch-thick stack of papers, instructions, and pamphlets. As he left his treatment planning visit, reeling from the emotional burden of his diagnosis and all the unfamiliar terminology, he didn’t know what to do or what to expect. Later, when he experienced early signs of tumor lysis syndrome, he struggled to reach his care team for triage and guidance. When he went to the emergency room, his oncologist was never informed.

This scenario is unfortunately common, and versions of this scenario play out thousands of times each day across the US health system. Within the clinic and hospital setting, patients receive excellent care from their providers, but a disconnect emerges once the patient leaves these medical settings: patients at home struggle to find guidance and support, while care teams lack the tools to engage patients between visits or monitor their health across care settings, providers, or episodes of care.

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.

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.

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

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.”

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.”

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.

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.
