Biopsychosocial factors and health outcomes associated with cannabis, opioids and benzodiazepines use among older veterans.

Background: Older Veterans may experience injuries that result in chronic pain and mental health conditions. Given the increasing availability of medical cannabis, it is important to examine if it serves as a viable or undesirable form of care relative to existing approaches.Objectives: We compared cannabis, prescription opioids, and benzodiazepines use between older Veteran and non-Veterans, and identified outcomes of cannabis use among Veterans. Because of the physical and mental conditions experienced by older Veterans we expected Veterans to report higher use of opioids and benzodiazepines compared to non-Veterans.Methods: We collected surveys from individuals aged 60 and older enrolled in the Illinois Medical Cannabis Patient Program and conducted logistic regression to identify factors associated with cannabis, opioids and benzodiazepines use between Veterans (N = 514, 90.2% male) and Non-Veterans (N = 2758, 41.1% male) across biopsychosocial factors.Results: Both groups reported similar levels of pain, quality of life, social satisfaction, and sleep quality. Veterans were more likely to use cannabis for mental health conditions (p = <.001) while they reported lower use for pain-related conditions (p = <.001) than non-Veterans. Veterans were less likely to use opioids (p = .013) and benzodiazepines (p < .01) compared to non-Veterans. Veterans also reported desirable health outcomes of cannabis use for pain, sleep quality, health conditions, and quality of life.Conclusions: Our work provides insights for clinicians and policy makers to consider whether cannabis can be a viable option to reduce or replace opioid and benzodiazepine use by older Veterans with chronic physical and mental health conditions.

Assessing Health-Related Outcomes of Medical Cannabis Use among Older Persons: Findings from Colorado and Illinois.

OBJECTIVES: To assess health-related outcomes associated with medical cannabis use among older patients in Colorado and Illinois enrolled in their home state's medical cannabis program. METHODS: Cross-sectional data from anonymous surveys were collected from 139 persons over the age of 60 using medical cannabis in the past year. We used structural equation modeling (SEM) to confirm the hypothesized four-factor structure that includes health-related quality of life (HRQL), health-care utilization (HCU), symptom effects, and adverse events. We then examined associations between cannabis use and self-reported outcome changes using linear regression. RESULTS: The four-factor model was the best fitting structure (X2(df) = 81.63 (67), p> X2 = 0.108) relative to reduced structures. We also found that using cannabis 1-4 times per week is associated with 3.30 additional points on the HRQL scale (p < .001), 2.72 additional points on the HCU scale (p < .01), and 1.13 points on pain (p < .001). The frequency of use reported at 5-7 times per week is associated with 4.71 additional HRQL score points (p < .001). No significant associations were observed between the frequency of use and adverse events. CONCLUSIONS: We observed how cannabis use outcomes fall into four independent factors, and those using more frequently reported higher values on HRQL, HCU, and pain measures. However, we are cautious about the generalizability of our findings. CLINICAL IMPLICATIONS: Clinicians should consider how older patients using medical cannabis can experience positive and negative outcomes simultaneously or separately and assess these outcomes directly along with considering patient self-reports.

Cannabis Use among Persons with Dementia and Their Caregivers: Lighting up an Emerging Issue for Clinical Gerontologists.

Objectives: Our goal is to illuminate cannabis use among persons with dementia (PwD) and their informal caregivers relative to the use of evidence-based as well as other complementary and alternative care practices. Methods: We analyzed focus group (FG) narratives provided by 26 caregivers of PwD and identified five themes concerning the provision of cannabis to PwD and caregivers' self-use. Results: Three of the 26 caregivers provided PwD cannabis and also used themselves, another 3 of the 26 used themselves only, and all but two of the remaining FG participants indicated they would consider providing cannabis to PwD or using for themselves. These caregivers expressed a desire to obtain more empirically-based information about cannabis and to discuss options with their clinical care providers. Conclusions: A small but significant proportion of caregivers are providing cannabis to PwD as a possible treatment for agitation, sleep disturbances and other problematic secondary symptoms and using for themselves as way to relieve stress. Many other caregivers may start using cannabis upon receiving information and guidance from a credible source. Clinical Implications: Notwithstanding the need for more research, clinical gerontologists and other dementia care specialists are being looked upon to provide information and guidance about the benefits and harms of cannabis use among PwD and their caregivers.

Impact of Stroke Call on the Stroke Neurology Workforce in the United States: Possible Challenges and Opportunities.

BACKGROUND: The Stroke & Vascular Neurology Section of the American Academy of Neurology was charged to identify challenges to the recruitment and retention of stroke neurologists and to make recommendations to address any identified problems. The Section initiated this effort by determining the impact of stroke on-call requirements as a barrier to the recruitment and retention of vascular neurologists. METHODS: This is a cross-sectional survey of a sample of US Neurologists providing acute stroke care. RESULTS: Of the 900 neurologists who were sent surveys, 313 (35%) responded. Of respondents from institutions providing stroke coverage, 71% indicated that general neurologists and 45% indicated that vascular neurologists provided that service. Of those taking stroke call, 36% agreed with the statement, "I spent too much time on stroke call," a perception that was less common among those who took less than 12-hour shifts (P < .0001); 21% who participated in stroke call were dissatisfied with their current job. Forty-six percent indicated that their stroke call duties contributed to their personal feeling of "burnout." CONCLUSIONS: Although the reasons are likely multifactorial, our survey of neurologists providing stroke care suggests that over-burdensome on-call responsibilities may be contributing to the vascular neurology workforce burnout and could be affecting recruitment and retention of vascular neurologists. Strategies to reduce the lifestyle impact of stroke call may help address this problem.

Defining doctoral gerontologists: Who are they and how are they contributing to the field of gerontology?

More than 300 individuals have earned doctoral degrees in gerontology since 1993, yet little is known about their training, professional placement, and contributions to the field. Given this lack of information, the authors sought to define the emerging mass of doctoral gerontologists. In this study, the authors analyzed results from the 2014 Gerontology Education Longitudinal Study survey sample of 84 individuals who earned a doctoral degree in gerontology between 1993 and 2013. Results revealed doctoral gerontologists completed training requirements that were consistent across eight programs offering doctorates in gerontology. The authors also found doctoral gerontologists have been successful in securing jobs in academic and nonacademic organizations, creating gerontological knowledge, and translating their work into other fields. The authors concluded by considering how the successful integration of doctoral gerontologists might continue, and they propose directions for future research.

Determinants of the Rigor of State Protection Policies for Persons With Dementia in Assisted Living.

Continued growth in the number of individuals with dementia residing in assisted living (AL) facilities raises concerns about their safety and protection. However, unlike federally regulated nursing facilities, AL facilities are state-regulated and there is a high degree of variation among policies designed to protect persons with dementia. Despite the important role these protection policies have in shaping the quality of life of persons with dementia residing in AL facilities, little is known about their formation. In this research, we examined the adoption of AL protection policies pertaining to staffing, the physical environment, and the use of chemical restraints. For each protection policy type, we modeled policy rigor using an innovative point-in-time approach, incorporating variables associated with state contextual, institutional, political, and external factors. We found that the rate of state AL protection policy adoptions remained steady over the study period, with staffing policies becoming less rigorous over time. Variables reflecting institutional policy making, including legislative professionalism and bureaucratic oversight, were associated with the rigor of state AL dementia protection policies. As we continue to evaluate the mechanisms contributing to the rigor of AL protection policies, it seems that organized advocacy efforts might expand their role in educating state policy makers about the importance of protecting persons with dementia residing in AL facilities and moving to advance appropriate policies.

Deploying an Ecological Model to Stem the Rising Tide of Firearm Suicide in Older Age.

A central objective of the Surgeon General's National Strategy for Suicide Prevention is to focus on older adults. We review individual risk-factors for suicide in late life and then introduce an ecological model to expand conceptualization of elder suicide. We first look at the role of firearms, providing evidence that firearm availability increases the means of elder suicide and gun access policies can contribute to reducing risk. Next, we focus on primary care providers, documenting how older adults often come into contact with these professionals before ending their lives and how these providers could take a more active role in mediating individual-level risk factors. We then turn our attention to the intersection between gun access and primary care and consider how advancing standards of care concerning gun access and suicide risk might be an effective policy alternative for blocking the pathway to suicide among older adults.

Autumn in New York: The Case of Long-Term Care Facilities in the "Safe Staffing" Lawsuit With Less Staffing But Similar COVID-19 Outcomes.

BACKGROUND AND OBJECTIVES: In 2022, 239 New York state long-term care facilities (LTCFs) challenged a "Safe Staffing" law in court. Our study compares LTCFs involved and not involved in the lawsuit, testing for differences in staffing measures and resident outcomes during the first year of the coronavirus disease 2019 (COVID-19) pandemic. RESEARCH DESIGN AND METHODS: New York LTCF-level data were obtained from the Centers for Medicare and Medicaid Services 2019 organization and 2020 COVID-19 data files. These data were then linked to data from the Long-Term Care Community Coalition, which identified the LTCFs involved in the "Safe Staffing" lawsuit. We first tested for differences in reported 2019 staffing levels by lawsuit involvement. Second, we specified "Doubly Robust" regression models to test if lawsuit involvement was associated with differences in resident COVID-19 infections, COVID-19 deaths, and overall mortality. RESULTS: LTCFs involved in the lawsuit reported lower staff ratings and fewer staffing hours compared to LTCFs not involved in the lawsuit. Despite finding higher rates of admissions with COVID-19 in LTCFs involved in the lawsuit, we did not find that COVID-19 infections, COVID-19 deaths, or overall mortality differed by lawsuit involvement. DISCUSSION AND IMPLICATIONS: LTCFs involved in the lawsuit were deemed by policymakers as reducing staff, earning excess profits, and placing residents at risk. While these LTCFs reported lower staffing levels, we observed no differences in resident outcomes during the first year of the COVID-19 pandemic. Researchers and policymakers should develop more nuanced perspectives concerning the relationship among LTCF staffing, outcomes, and organizational profitability.

Unrelenting Growth and Diversification: Using the Health and Retirement Study to Illuminate Cannabis Use Among Aging Americans.

BACKGROUND AND OBJECTIVES: Cannabis use among aging Americans continues to increase. We examine correlates of cannabis use including attitudes, state of residence, health status, and service use. RESEARCH DESIGN AND METHODS: Using the 2018 Health and Retirement Study Cannabis module completed by 1,372 respondents aged 50 and older, we distinguished current cannabis users from those who have never used or have some prior use. We linked 2018 and 2016 core HRS data and used multinomial regressions to identify associations among current use, attitudes, place of residence, as well as current (2018) and past (2016) medical conditions, pain, and sleep issues. We also examined associations among cannabis use, hospital stays, and outpatient medical visits. RESULTS: Past-year cannabis use reached 10.3% among aging Americans. Attitudes toward cannabis have changed over time with 4 of 5 survey respondents currently holding a favorable attitude. Attitude and state of residence were associated with current use. Cannabis users reported higher levels of pain, were more likely to use prescription opioids, and report activity limitations in both 2016 and 2018. Associations between cannabis use and sleep issues or concurrent healthcare use were not observed. DISCUSSION AND IMPLICATIONS: Changing attitudes and state legalization appear important for late middle-aged and older persons, and as many as 1 of every 5 persons over 50 may be using cannabis by 2030. Cannabis use among aging Americans warrants increased attention from care providers, program administrators, and policymakers, especially as a prevention or harm reduction strategy relative to prescription opioids.

Offering an Alternative to Persons with Chronic Pain: How Access to Cannabis May Provide an Off-Ramp from Undesired Prescription Opioid Use.

Background: Chronic pain (CP) is experienced by as many as 50 million Americans and can negatively impact physical and mental health. Prescribing opioids is the most common approach to address moderate to severe CP though these potent analgesics are associated with a significant number of side effects. One alternative some Americans are turning to for CP management is cannabis. In addition to serving as an alternative, many individuals with CP use cannabis in addition to using prescription opioids. This study examined individuals with CP who enrolled in the state of Illinois' opioid diversion program, the Opioid Alternative Pilot Program (OAPP), which offers individuals aged 21 and older a separate pathway to access medical cannabis if they have or could receive a prescription for opioids as certified by a licensed physician. Methods: Cross-sectional survey data were collected from 450 participants. We described participants and compared those who use only cannabis with those who use cannabis and opioids. Results: While 16% of the respondents were cannabis-only users, 84% of the respondents were co-users of opioids and cannabis. Both groups considered opioid use risky (100% cannabis-only, 89% co-users,). The majority (73%) of respondents sought to completely stop or never start using opioids for CP. Cannabis-only users reported lower levels of pain compared to co-users. Co-users (85%) were more likely to have their routine provider as a cannabis certifying physician than cannabis-only users (69%). Conclusion: With increasing clinical evidence, legalization and acceptance, researchers should continue to examine how cannabis may be a viable alternative to reduce the risk of prescription opioid side effects, misuse, or dependence. Our findings also inform health care providers and state policymakers who increasingly are being asked to consider how cannabis may reduce the potential for harmful outcomes among persons with CP who use prescription opioids.

Pathways into Assisted Living Communities: Admission Limitations and Assessment Requirements Across the United States.

OBJECTIVES: Limitations to admission play a critical role in shaping the composition of residents residing within licensed assisted living (AL) communities. DESIGN: We document variation across 165 licensure classifications in how state agencies limit who AL communities may admit and what assessments are required to make those determinations. SETTING AND PARTICIPANTS: AL regulations and licensed AL communities across all 50 states in 2018. METHODS: We estimated the proportion of all licensed AL communities regulated by admission limitations and identified groups consisting of those that limit admission based on a health-related condition, specified behavior, mental health condition, and/or cognitive impairment as well as those that impose no limitations to admission. We also estimated the proportion of all licensed AL communities required to conduct assessments at time of admission. RESULTS: The largest group of ALs (29% nationally) is governed by regulations limiting the admission of persons with a health condition. The next largest group of AL communities (23.6%) limit admissions based on health, specified behavior, mental health conditions, and cognitive impairment. In contrast, 11.1% of licensed AL communities have no regulations restricting admissions. We also found that more than 8 of every 10 licensed communities were required to have residents complete a health assessment at admission, but less than half were required to complete a cognitive assessment. CONCLUSIONS AND IMPLICATIONS: The variation we observe implies that state agencies have created multiple licensure classifications that serve as a mechanism for sorting types of residents into settings based on their need (eg, health, mental health, cognitive). Although future research should investigate the implications of this regulatory diversity, the categories outlined here may be helpful to clinicians, consumers, and policy makers to better understand the options in their state and how various AL licensure classifications compare to one another.

Critical Elements of Care Coordination for Older Persons in Rural Communities: An Evaluation of the Iowa Return to Community Service Demonstration.

We evaluated the Iowa Return to Community, a service demonstration designed to coordinate care and reduce preventable healthcare utilization among at-risk older persons living at home in rural communities. During 2021, 262 older persons elected to participate in the IRTC program. Individuals who participated were more likely to live in micropolitan areas (OR = 2.30, 95% CI 1.34-3.95) relative to metropolitan locations. Individuals who used recommended services were more likely to be men (OR 3.65, 95% CI 1.16-11.51) and more likely to live in rural (OR 17.48, 95% CI 1.37-223.68) and micropolitan areas (OR 3.17, 95% CI 1.00-10.05). However, prevention of health care use corresponded more with consistent and prolonged IRTC program engagement rather than volume of service use. The IRTC constitutes a population aging and rural health strategy to reduce unnecessary health care use while supporting individual preferences to remain at home.

Chiropractic episodes and the co-occurrence of chiropractic and health services use among older Medicare beneficiaries.

OBJECTIVE: The purpose of this study was to define and characterize episodes of chiropractic care among older Medicare beneficiaries and to evaluate the extent to which chiropractic services were used in tandem with conventional medicine. METHODS: Medicare Part B claims histories for 1991 to 2007 were linked to the nationally representative survey on Assets and Health Dynamics among the Oldest Old baseline interviews (1993-1994) to define episodes of chiropractic sensitive care using 4 approaches. Chiropractic and nonchiropractic patterns of service use were examined within these episodes of care. Of the 7447 Assets and Health Dynamics among the Oldest Old participants, 971 used chiropractic services and constituted the analytic sample. RESULTS: There were substantial variations in the number and duration of episodes and the type and volume of services used across the 4 definitions. Depending on how the episode was constructed, the mean number of episodes per chiropractic user ranged from 3.74 to 23.12, the mean episode duration ranged from 4.7 to 28.8 days, the mean number of chiropractic visits per episode ranged from 0.88 to 2.8, and the percentage of episodes with co-occurrent use of chiropractic and nonchiropractic providers ranged from 4.9% to 10.9% over the 17-year period. CONCLUSION: Treatment for back-related musculoskeletal conditions was sought from a variety of providers, but there was little co-occurrent service use or coordinated care across provider types within care episodes. Chiropractic treatment dosing patterns in everyday practice were much lower than that used in clinical trial protocols designed to establish chiropractic efficacy for back-related conditions.

Medical Cannabis and Utilization of Nonhospice Palliative Care Services: Complements and Alternatives at End of Life.

BACKGROUND AND OBJECTIVES: There is a need to know more about cannabis use among terminally diagnosed older adults, specifically whether it operates as a complement or alternative to palliative care. The objective is to explore differences among the terminal illness population within the Illinois Medical Cannabis Program (IMCP) by their use of palliative care. RESEARCH DESIGN AND METHODS: The study uses primary, cross-sectional survey data from 708 terminally diagnosed patients, residing in Illinois, and enrolled in the IMCP. We compared the sample on palliative care utilization through logistic regression models, examined associations between palliative care and self-reported outcome improvements using ordinary least squares regressions, and explored differences in average pain levels using independent t-tests. RESULTS: 115 of 708 terminally diagnosed IMCP participants were receiving palliative care. We find increased odds of palliative care utilization for cancer (odds ratio [OR] [SE] = 2.15 [0.53], p < .01), low psychological well-being (OR [SE] = 1.97 [0.58], p < .05), medical complexity (OR [SE] = 2.05 [0.70], p < .05), and prior military service (OR [SE] = 2.01 [0.68], p < .05). Palliative care utilization is positively associated with improvement ratings for pain (7.52 [3.41], p < .05) and ability to manage health outcomes (8.29 [3.61], p < .01). Concurrent use of cannabis and opioids is associated with higher pain levels at initiation of cannabis dosing (p < .05). DISCUSSION AND IMPLICATIONS: Our results suggest that cannabis is largely an alternative to palliative care for terminal patients. For those in palliative care, it is a therapeutic complement used at higher levels of pain.

Cannabis and End-of-Life Care: A Snapshot of Hospice Planning and Experiences Among Illinois Medical Cannabis Patients With A Terminal Diagnosis.

INTRODUCTION: Between 2013 and 2019, Illinois limited cannabis access to certified patients enrolled in the Illinois Medical Cannabis Program (IMCP). In 2016, the state instituted a fast-track pathway for terminal patients. The benefits of medicinal cannabis (MC) have clear implications for patients near end-of-life (EOL). However, little is known about how terminal patients engage medical cannabis relative to supportive care. METHODS: Anonymous cross-sectional survey data were collected from 342 terminal patients who were already enrolled in (n = 19) or planning to enroll (n = 323) in hospice for EOL care. Logistic regression models compare patients in the sample on hospice planning vs. hospice enrollment, use of palliative care vs. hospice care, and use standard care vs non-hospice palliative care. RESULTS: In our sample, cancer patients (OR = 0.21 (0.11), p < .01), and those who used the fast-track application into the IMCP (OR = 0.11 (0.06), p < .001) were less likely to be enrolled in hospice. Compared to patients in palliative care, hospice patients were less likely to report cancer as their qualifying condition (OR = 0.16 (0.11), p < .01), or entered the IMCP via the fast-track (OR = 0.23 (0.15), p < .05). DISCUSSION: Given low hospice enrollment in a fairly large EOL sample, cannabis use may operate as an alternative to supportive forms of care like hospice and palliation. Clinicians should initiate conversations about cannabis use with their patients while also engaging EOL Care planning discussions as an essential part of the general care plan.

Promoting Quality of Life and Safety in Assisted Living: A Survey of State Monitoring and Enforcement Agents.

Our goal was to learn about monitoring and enforcement of state assisted living (AL) regulations. Using survey responses provided in 2019 from administrative agents across 48 states, we described state agency structures, accounted for operational processes concerning monitoring and enforcement, and documented data collecting and public reporting efforts. In half of the states, oversight of AL was dispersed across three or more agencies, and administrative support varied in terms of staffing and budget allocations. Operations also varied. While most agents could deploy a range of monitoring and enforcement tools, less than half compiled data concerning inspections, violations, and penalties. Less than 10 states shared such information in a manner that was easily accessible to the public. Future research should determine how these varied administrative structures and processes deter or contribute to AL communities' efforts to implement regulations designed to promote quality of life and provide for the safety of residents.

Long-term declines in ADLs, IADLs, and mobility among older Medicare beneficiaries.

BACKGROUND: Most prior studies have focused on short-term (≤ 2 years) functional declines. But those studies cannot address aging effects inasmuch as all participants have aged the same amount. Therefore, the authors studied the extent of long-term functional decline in older Medicare beneficiaries who were followed for varying time lengths, and the authors also identified the risk factors associated with those declines. METHODS: The analytic sample included 5,871 self- or proxy-respondents who had complete baseline and follow-up survey data that could be linked to their Medicare claims for 1993-2007. Functional status was assessed using activities of daily living (ADLs), instrumental ADLs (IADLs), and mobility limitations, with declines defined as the development of two of more new difficulties. Multiple logistic regression analysis was used to focus on the associations involving respondent status, health lifestyle, continuity of care, managed care status, health shocks, and terminal drop. RESULTS: The average amount of time between the first and final interviews was 8.0 years. Declines were observed for 36.6% on ADL abilities, 32.3% on IADL abilities, and 30.9% on mobility abilities. Functional decline was more likely to occur when proxy-reports were used, and the effects of baseline function on decline were reduced when proxy-reports were used. Engaging in vigorous physical activity consistently and substantially protected against functional decline, whereas obesity, cigarette smoking, and alcohol consumption were only associated with mobility declines. Post-baseline hospitalizations were the most robust predictors of functional decline, exhibiting a dose-response effect such that the greater the average annual number of hospital episodes, the greater the likelihood of functional status decline. Participants whose final interview preceded their death by one year or less had substantially greater odds of functional status decline. CONCLUSIONS: Both the additive and interactive (with functional status) effects of respondent status should be taken into consideration whenever proxy-reports are used. Encouraging exercise could broadly reduce the risk of functional decline across all three outcomes, although interventions encouraging weight reduction and smoking cessation would only affect mobility declines. Reducing hospitalization and re-hospitalization rates could also broadly reduce the risk of functional decline across all three outcomes.

Older adults who persistently present to the emergency department with severe, non-severe, and indeterminate episode patterns.

BACKGROUND: It is well known that older adults figure prominently in the use of emergency departments (ED) across the United States. Previous research has differentiated ED visits by levels of clinical severity and found health status and other individual characteristics distinguished severe from non-severe visits. In this research, we classified older adults into population groups that persistently present with severe, non-severe, or indeterminate patterns of ED episodes. We then contrasted the three groups using a comprehensive set of covariates. METHODS: Using a unique dataset linking individual characteristics with Medicare claims for calendar years 1991-2007, we identified patterns of ED use among the large, nationally representative AHEAD sample consisting of 5,510 older adults. We then classified one group of older adults who persistently presented to the ED with clinically severe episodes and another group who persistently presented to the ED with non-severe episodes. These two groups were contrasted using logistic regression, and then contrasted against a third group with a persistent pattern of ED episodes with indeterminate levels of severity using multinomial logistic regression. Variable selection was based on Andersen's behavioral model of health services use and featured clinical status, demographic and socioeconomic characteristics, health behaviors, health service use patterns, local health care supply, and other contextual effects. RESULTS: We identified 948 individuals (17.2% of the entire sample) who presented a pattern in which their ED episodes were typically defined as severe and 1,076 individuals (19.5%) who typically presented with non-severe episodes. Individuals who persistently presented to the ED with severe episodes were more likely to be older (AOR 1.52), men (AOR 1.28), current smokers (AOR 1.60), experience diabetes (AOR (AOR 1.80), heart disease (AOR 1.70), hypertension (AOR 1.32) and have a greater amount of morbidity (AOR 1.48) than those who persistently presented to the ED with non-severe episodes. When contrasted with 1,177 individuals with a persistent pattern of indeterminate severity ED use, persons with severe patterns were older (AOR 1.36), more likely to be obese (AOR 1.36), and experience heart disease (AOR 1.49) and hypertension (AOR 1.36) while persons with non-severe patterns were less likely to smoke (AOR 0.63) and have diabetes (AOR 0.67) or lung disease (AOR 0.58). CONCLUSIONS: We distinguished three large, readily identifiable groups of older adults which figure prominently in the use of EDs across the United States. Our results suggest that one group affects the general capacity of the ED to provide care as they persistently present with severe episodes requiring urgent staff attention and greater resource allocation. Another group persistently presents with non-severe episodes and creates a considerable share of the excess demand for ED care. Future research should determine how chronic disease management programs and varied co-payment obligations might impact the use of the ED by these two large and distinct groups of older adults with consistent ED use patterns.

A prospective cohort study of long-term cognitive changes in older Medicare beneficiaries.

BACKGROUND: Promoting cognitive health and preventing its decline are longstanding public health goals, but long-term changes in cognitive function are not well-documented. Therefore, we first examined long-term changes in cognitive function among older Medicare beneficiaries in the Survey on Assets and Health Dynamics among the Oldest Old (AHEAD), and then we identified the risk factors associated with those changes in cognitive function. METHODS: We conducted a secondary analysis of a prospective, population-based cohort using baseline (1993-1994) interview data linked to 1993-2007 Medicare claims to examine cognitive function at the final follow-up interview which occurred between 1995-1996 and 2006-2007. Besides traditional risk factors (i.e., aging, age, race, and education) and adjustment for baseline cognitive function, we considered the reason for censoring (entrance into managed care or death), and post-baseline continuity of care and major health shocks (hospital episodes). Residual change score multiple linear regression analysis was used to predict cognitive function at the final follow-up using data from telephone interviews among 3,021 to 4,251 (sample size varied by cognitive outcome) baseline community-dwelling self-respondents that were ≥ 70 years old, not in managed Medicare, and had at least one follow-up interview as self-respondents. Cognitive function was assessed using the 7-item Telephone Interview for Cognitive Status (TICS-7; general mental status), and the 10-item immediate and delayed (episodic memory) word recall tests. RESULTS: Mean changes in the number of correct responses on the TICS-7, and 10-item immediate and delayed word recall tests were -0.33, -0.75, and -0.78, with 43.6%, 54.9%, and 52.3% declining and 25.4%, 20.8%, and 22.9% unchanged. The main and most consistent risks for declining cognitive function were the baseline values of cognitive function (reflecting substantial regression to the mean), aging (a strong linear pattern of increased decline associated with greater aging, but with diminishing marginal returns), older age at baseline, dying before the end of the study period, lower education, and minority status. CONCLUSIONS: In addition to aging, age, minority status, and low education, substantial and differential risks for cognitive change were associated with sooner vs. later subsequent death that help to clarify the terminal drop hypothesis. No readily modifiable protective factors were identified.
