Background: Low nursing home staffing in the United States is a growing safety concern. Socioeconomic deprivation in the local areas surrounding a nursing home may be a barrier to improving staffing rates but has been poorly studied. Thus, the objective of this paper was to assess the relationship between neighborhood deprivation and nursing home staffing in the United States. Methods: This cross-sectional study used 2018 daily payroll-based staffing records and address data for 12,609 nursing homes in the United States linked with resident assessment data. Our primary exposure of interest was severe economic deprivation at the census block group (neighborhood) level, defined as an area deprivation index score ≥85/100. The primary outcome was hours worked per resident-day among nursing home employees providing direct resident care. Marginal linear regression models and generalized estimating equations with robust sandwich-type standard errors were used to estimate associations between severe neighborhood deprivation and staffing rates. Results: Compared to less deprived neighborhoods, unadjusted staffing rates in facilities located within severely deprived neighborhoods were 38% lower for physical and occupational therapists, 30% lower for registered nurses (RNs), and 5% lower for certified nursing assistants. No disparities in licensed practical nurse (LPN) staffing were observed. In models with state-level and rurality fixed effects and clustered on the county, a similar pattern of disparities was observed. Specifically, RN staffing per 100 resident-days was significantly lower in facilities located within severely deprived neighborhoods as compared to those in less deprived areas (mean difference: 5.6 fewer hours, 95% confidence interval [CI] 4.2–6.9). Disparities of lower magnitude were observed for other clinical disciplines except for LPNs. Conclusions: Significant staffing disparities were observed within facilities located in severely deprived neighborhoods. Targeted interventions, including workforce recruitment and retention efforts, may be needed to improve staffing levels for nursing homes in deprived neighborhoods. [ABSTRACT FROM AUTHOR]

Objectives To describe methodological approaches to population targeting and sampling and to summarize limitations of Internet-based questionnaires in older adults. Design Systematic literature review. Setting Studies using online questionnaires in older adult populations. Participants English-language articles using search terms for geriatric, age 65 and over, Internet survey, online survey, Internet questionnaire, and online questionnaire in Pub Med and EBSCO host between 1984 and July 2012. Inclusion criteria were study population mean age 65 and older and use of an online questionnaire for research. Review of 336 abstracts yielded 14 articles for full review by two investigators; 11 articles met inclusion criteria. Measurements Articles were extracted for study design and setting, participant characteristics, recruitment strategy, country, and study limitations. Results Eleven articles were published after 2001. Studies had populations with a mean age of 65 to 78, included descriptive and analytical designs, and were conducted in the United States, Australia, and Japan. Recruiting methods varied widely from paper fliers and personal e-mails to use of consumer marketing panels. Investigator-reported study limitations included the use of small convenience samples and limited generalizability. Conclusion Online questionnaires are a feasible method of surveying older adults in some geographic regions and for some subsets of older adults, but limited Internet access constrains recruiting methods and often limits study generalizability.

Introduction: For most older adults with dementia, the short‐term harms and burdens of routine cancer screening likely outweigh the delayed benefits. We aimed to provide a more updated assessment of the extent that US older adults with dementia receive breast and prostate cancer screenings. Methods: Using the Health and Retirement Study (HRS) Wave 12 (2014–2015) linked to Medicare, we examine rates of breast and prostate cancer screenings in adults 65+ years by cognitive status. We used claims data to identify eligibility for screening and receipt of screening. We used a validated method using HRS data to define cognitive status. Results: The analytic sample included 2439 women in the breast cancer screening cohort and 1846 men in the prostate cancer screening cohort. Average ages were 76.8 years for women and 75.6 years for men, with 9.0% and 7.6% with dementia in each cohort, respectively. Among women with dementia, 12.3% were screened for breast cancer. When stratified by age, 10.6% of those 75+ and have dementia were screened for breast cancer. When stratified by predicted life expectancy, 10.4% of those with predicted life expectancy of <10 years and have dementia were screened for breast cancer. Among men with dementia, 33.9% were screened for prostate cancer. When stratified by age, 30.9% of those 75+ and have dementia were screened for prostate cancer. When stratified by predicted life expectancy, 34.4% of those with predicted life expectancy of <10 years and have dementia were screened for prostate cancer. Using multivariable logistic regression, dementia was associated with lower odds of receiving breast cancer screening (OR 0.36, 95% CI 0.23–0.57) and prostate cancer screening (OR 0.58, 95% CI 0.36–0.96). Discussion: Our results suggest potential over‐screening in older adults with dementia. Better supporting dementia patients and caregivers to make informed cancer screening decisions is critical.

Background: Family caregivers offer essential support to persons living with dementia (PLWD). Providing care for more than one family member or close other across adulthood is becoming increasingly common, yet little is known about the ways that caregiving experiences shape caregiver preparedness. The current study presents a grounded theory of future caregiver preparedness in former caregivers of PLWD. Method: A coding team (five coders and two auditors) used Consensual Qualitative Research and grounded theory techniques to analyze transcripts from 32 semi‐structured interviews with midlife former caregivers of parents who died following advanced Alzheimer's disease and related dementias. Results: Qualitative analysis revealed two dimensions of future caregiver preparedness: caregiving confidence and caregiving insights. Narratives from caregiving experiences informed participants' descriptions of their future caregiver preparedness. Though some former caregivers described a positive (i.e., boosted or sustained) sense of caregiving confidence following care for their parents, others described a diminished (i.e., restricted or impeded) sense of confidence. Regardless of their confidence, all caregivers described specific caregiving insights related to one or more categories (i.e., caregiving self‐conduct, care systems and resources, and relating with a care partner). Conclusions: Preparedness for future caregiving following recent care for a PLWD varies: For some, past experiences appear to offer cumulative advantages in anticipating future care roles, whereas for others, past experiences may contribute to apprehension towards, or rejection of, future care roles. Entering new caregiving roles with diminished confidence may have negative consequences for caregivers' and care partners' wellbeing. Multidimensional assessment of future caregiver preparedness in former caregivers of PLWD may support development of resources for former caregivers entering new caregiving roles.

Background: Social isolation is a key public health concern and has been associated with numerous negative health consequences. Technology is increasingly thought of as a solution to address social isolation. This study examines the longitudinal association between the access and use of technology and social isolation in older adults 65 and older, living in the United States. Methods: This observational cohort study included community‐dwelling older adults (N = 6704) who participated in the National Health and Aging Trends Study. Regression analyses were conducted using data from 2015 to 2019. Information about technology access and use was ascertained using self‐reported questionnaires. The primary outcome was the risk of social isolation. Results: At baseline, the majority of older adults that were not socially isolated had a working cell phone (88%) or computer (71%) and used email or text messaging (56%). Older adults that had access to (cell phone‐ incidence rate ratio [IRR] 0.62 [95% CI 0.48–0.81]; computer‐ IRR 0.63 [95% CI 0.51–0.78]), and used technology (email or text messaging‐ IRR 0.64 [95% CI 0.51–0.80]) in the year prior had a lower risk of social isolation than older adults who reported they did not access or use technology. Additionally, over four years, older adults who reported that they had access to a computer had a lower risk (0.69 [0.57, 0.84]) for social isolation than their counterparts. Conclusion: In this cohort study, technology access was associated with a lower risk for social isolation among community‐dwelling older adults. These findings suggest that technology has an important role in approaches that seek to prevent social isolation among older adults. [ABSTRACT FROM AUTHOR]

Background: Despite possible major adverse cognitive, physical, social, and behavioral consequences, little is known about how persons living with dementia perceive satisfaction with life, a key component of well‐being. We sought to examine (i) whether persons living with dementia perceive a lower level of satisfaction compared to their peers without dementia and (ii) whether the associations between individual characteristics and life satisfaction are different between persons living with and without dementia. Methods: Using a nationally representative sample of community‐dwelling older adults aged ≥70 years in the U.S. from the Health and Retirement Study, we compared scores on the Satisfaction with Life Scale (SWLS), a self‐reported 5‐item scale ranging from 1 to 7 (more satisfaction), between persons with probable dementia (n = 341) and those without (n = 5530), adjusting for individual characteristics. We also tested whether the associations between the individual characteristics and SWLS differ by dementia status. Results: Scores on SWLS did not differ between persons with probable dementia and those without when adjusting for individual characteristics including limitations in activities of daily living (ADL) (adjusted difference, −0.09; 95% CI, −0.33 to +0.15; p‐value, 0.45). However, dementia status was associated with lower life satisfaction through the mediation of limitations in ADL (total effect, −0.29; bootstrapped 95% CI, −0.47 to −0.12). Most individual characteristics associated with lower life satisfaction were similar in the two groups, including younger age, more limitations in ADL, and depression. Less wealth was associated with lower satisfaction among persons without dementia but not among those with probable dementia. Conclusions: Dementia status was only modestly associated with lower life satisfaction through the mediation of limitations in ADL among participants who were able to provide response. Future research is warranted to determine whether life satisfaction can be used as a meaningful outcome when evaluating well‐being among persons living with dementia. [ABSTRACT FROM AUTHOR]

Background: The contemporary uptake of lipid‐lowering therapies (LLT), including more intensive treatment with high‐intensity statins and non‐statin LLT, among U.S. older adults (≥75 years old) with ASCVD is unknown. Methods: In this multicenter retrospective cohort study of a large geographically diverse sample of commercially insured U.S. older adults with ASCVD, we assessed treatment with LLT. Secondary measures included LDL‐C above target ≥70 mg/dl, persistence and adherence to therapy. Results: Treatment with statins, high‐intensity statins, ezetimibe, and PCSK9 inhibitors was assessed in 194,503 older adults (49.9% female) with known ASCVD on January 31st, 2019. 49.3% of older adults with ASCVD were on any statin, with 16.6% receiving a high‐intensity statin and 32.7% on low‐or moderate‐intensity statins. Treatment with ezetimibe (2.4%) or PCSK9 inhibitors (0.24%) was rare and 62.6% of the overall cohort had an LDL‐C above target at ≥70 mg/dl. Patients on high‐intensity statins were more frequently male, had a diagnosis of coronary artery disease, and were more frequently seen by a cardiologist compared with those on low‐or moderate‐intensity statins and untreated individuals (p < 0.0001). The majority of older adults on high‐intensity statins remained on therapy at 12 months (91.9%) and 85.7% had ≥75% adherence to treatment. Conclusions: Less than half of eligible older adults with ASCVD are on statins and only a minority of patients are receiving more intensive lipid‐lowering to improve outcomes. [ABSTRACT FROM AUTHOR]

Background: Racial inequality in functional trajectories has been well documented in the U.S. civilian population but has not been explored among Veterans. Our objectives were to: (1) assess how functional trajectories differed for Black and White Veterans aged ≥50 and (2) explore how socioeconomic, psychosocial, and health‐related factors altered the relationship between race and function. Methods: We conducted a prospective, longitudinal analysis using the 2006–2016 Health and Retirement Study. The study cohort included 3700 Veterans who self‐identified as Black or White, responded to baseline psychosocial questionnaires, and were community‐dwelling on first observation. We used stepwise and stratified linear mixed effects models of biannually assessed functional limitations. The outcome measure was as a count of functional limitations. Race was measured as respondent self‐identification as Black or White. Demographic measures included gender and age. Socioeconomic resources included partnership status, education, income, and wealth. Psychosocial stressors included exposure to day‐to‐day and major discrimination, traumatic life events, stressful life events, and financial strain. Health measures included chronic and mental health diagnoses, smoking, rurality, and use of Veterans Affairs services. Results: Black Veterans developed functional limitations at earlier ages and experienced faster functional decline than White Veterans between the ages of 50 and 70, with convergence occurring at age 85. Once we accounted for economic resources and psychosocial stressors in multivariable analyses, the association between race and the number of functional limitations was no longer statistically significant. Lower wealth, greater financial strain, and traumatic life events were significantly associated with functional decline. Conclusions: Health systems should consider how to track Veterans' function earlier in the life course to ensure that Black Veterans are able to get timely access to services that may slow premature functional decline. Providers may benefit from training about the role of economic resources and psychosocial stressors in physical health outcomes. [ABSTRACT FROM AUTHOR]

Background: The comparative safety of sulfonylureas (SUs) in nursing home (NH) residents remains understudied despite widespread use. We compared the effects of three SU medications and initial SU doses on adverse glycemic and cardiovascular events among NH residents. Methods: This national retrospective cohort study linked Medicare claims with Minimum Data Set 2.0 assessments for long‐stay NH residents aged ≥65 years between January 2008 and September 2010. Exposures were the SU medication initiated (glimepiride, glipizide, or glyburide) and doses (standard or reduced). One‐year outcomes were hospitalizations or emergency department visits for severe hypoglycemia, heart failure (HF), stroke, and acute myocardial infarction (AMI). After the inverse probability of treatment and inverse probability of censoring by death weighting, we estimated hazard ratios (HR) using Cox regression models with robust 95% confidence intervals (CI). Results: The cohort (N = 6821) included 3698 new glipizide, 1754 glimepiride, and 1369 glyburide users. Overall, the mean (standard deviation) age was 81.4 (8.2) years, 4816 (70.6%) were female, and 5164 (75.7%) were White non‐Hispanic residents. The rates of severe hypoglycemia were 30.3 (95% CI 22.3–40.1), 49.0 (95% CI 34.5–67.5), and 35.9 (95% CI 22.2–54.9) events per 1000 person‐years among new glipizide, glimepiride, and glyburide users, respectively (glimepiride versus glipizide HR 1.6, 95% CI 1.0–2.4, p = 0.04; glyburide versus glipizide HR 1.2, 95% CI 0.7–1.9, p = 0.59). The rates of severe hypoglycemia were 27.1 (95% CI 18.6–38.0) and 42.8 (95% CI 33.6–53.8) events per 1000 person‐years among new users of reduced and standard SU doses, respectively (HR 2.2, 95% CI 1.4–3.5, p < 0.01). Rates of HF, stroke, and AMI were similar between medications and doses. Conclusions: Among long‐stay NH residents, new use of glimepiride and standard SU doses resulted in higher rates of severe hypoglycemic events. Cardiovascular outcomes may not be affected by the choice of SU medication or dose. [ABSTRACT FROM AUTHOR]

The article presents a study which examined the association between social isolation and incident dementia over nine years in large and nationally representative sample of Medicare beneficiaries in the U.S. Topics include criteria for participants to be classified as having probable dementia, distribution of baseline participant characteristics, and characteristics of baseline participants for the total sample and by social isolation status.

Background: Heart failure (HF) is the leading cause of hospitalization among older adults in the United States and results in high rates of post-acute care (PAC) utilization. Federal policies have focused on shifting PAC to less intensive settings and reducing length of stay to lower spending. This study evaluates the impact of policy changes on PAC use among Medicare beneficiaries hospitalized with HF between 2008 and 2015 by (1) characterizing trends in PAC use and cost and (2) evaluating changes in readmission, mortality, and days in the community, overall and by frailty. Methods: Annual cross-section prospective cohorts of all HF admissions between 1/1/2008 and 9/30/2015 among a 20% random sample of all Medicare Fee-for-Service beneficiaries (n = 718,737). The Claims-based Frailty Index (CFI) was used to classify frailty status. Multivariable regression models were used to evaluate trends in first discharge location, readmissions, mortality, days alive in the community, and costs; overall and by frailty status. Results: Frailty was prevalent among HF patients: 54.1% were prefrail, 37.0% mildly frail, and 6.9% moderate to severely frail. Between 2008 and 2015, almost 4% more HF beneficiaries received PAC, with most of the increase concentrated in skilled nursing facilities (SNF) (+2.3%) and home health agencies (HHA) (+1.1%), and PAC cost increased by $123 (3.5%). Over the 180-days follow-up after hospitalization, hospital readmissions decreased significantly (-3.4% at 30-day; -6.3% at 180-day), days alive in the community increased (+1.5), and 180-day Medicare costs declined $2948 (-18.7%) without negative impact in mortality (except a minor increase in the pre-frail group). Gains were greatest among the frailest patients. Conclusions: Medicare beneficiaries hospitalized with HF spent more time in the community and experienced lower rehospitalization rates at lower cost without significant increases in mortality. However, important opportunities remain to optimize care for frail older adults hospitalized with HF. [ABSTRACT FROM AUTHOR]

Background: Many U.S. caregivers provide care to the generation above and below simultaneously, described as “sandwich” generation caregivers. We seek to provide the first national estimates characterizing sandwich generation caregivers and the older adults for whom they care. Methods: We used the 2015 National Study of Caregiving (NSOC) and National Health and Aging Trends Study (NHATS) to compare individual (demographic, socio-economic, health, and caregiving characteristics) and caregiving-related experience (financial and emotional difficulties, caregiver role overload and gains, supportive services, employment and participation restrictions) between sandwich and non-sandwich generation caregivers. The analysis included adult child caregivers with or without any minor child under 18 years (n = 194 and 912 NSOC respondents, respectively) providing care to n = 436 and 1217 older adult NHATS respondents. Results: Of all adult child caregivers, 24.3% also cared for a minor child (i.e., sandwich generation caregivers), representing 2.5 million individuals. Sandwich generation caregivers provided similar care hours to older care recipients as non-sandwich caregivers (77.4 vs. 71.6 h a month, p = 0.60), though more of them worked for pay (69.4% vs. 53.9%, p = 0.002). Both sandwich generation caregivers (21.0% vs. 11.1%, p = 0.005) and their care recipients (30.1% vs. 20.9%, p = 0.006) were more likely to be Medicaid enrollees than their non-sandwich caregiving counterparts. More sandwich generation caregivers reported substantial financial (23.5% vs. 12.2%, p < 0.001) and emotional difficulties (44.1% vs. 32.2%, p = 0.02) than non-sandwich caregivers; they also reported higher caregiver role overload (score: 2.9 vs. 2.4, p = 0.04). Their supportive services use was similarly low as non-sandwich caregivers except for seeking financial help (24.8% vs. 14.7%, p = 0.008). Conclusions: Besides caring for minor child(ren), sandwich generation caregivers provided similarly intense care to care recipients as nonsandwich caregivers and had higher labor force participation; they experienced more caregiving-related financial and emotional difficulties and role overload. Policymakers may consider supportive services that address their unique needs and roles. [ABSTRACT FROM AUTHOR]

Background: Assessing activity limitations is central to aging research. However, assessments of activity limitations vary, and this may have implications for the populations identified. We aim to compare measures of activities of daily living (ADLs) and their resulting prevalence and mortality across three nationally-representative cohort studies: the National Health and Aging Trends Study (NHATS), the Health and Retirement Survey (HRS), and the Medicare Current Beneficiary Survey (MCBS). Methods: We compared the phrasing and context of questions around help and difficulty with six self-care activities: eating, bathing, toileting, dressing, walking inside, and transferring. We then compared the prevalence and 1-year mortality for difficulty and help with eating and dressing. Results: NHATS, HRS, and MCBS varied widely in phrasing and framing of questions around activity limitations, impacting the proportion of the population found to experience difficulty or receive help. For example, in NHATS 12.4% [95% confidence interval (CI) 11.5%–13.4%] of the cohort received help with dressing, while in HRS this figure was 6.4% [95% CI 5.7%–7.2%] and MCBS 5.3% [95% CI 4.7%–5.8%]. When combined with variation in sampling frame and survey approach of each survey, such differences resulted in large variation in estimates of the older population of older adults with ADL disability. Conclusions: In order to take late-life activity limitations seriously, we must clearly define the measures we use. Further, researchers and clinicians seeking to understand the experience of older adults with activity limitations should be careful to interpret findings in light of the framing of the question asked.

Background: Traumatic brain injury (TBI) is a leading cause of death and disability in older adults. The aim of this study was to characterize the burden of TBI in older adults by describing demographics, care location, diagnoses, outcomes, and payments in this high‐risk group. Methods: Using 2016–2019 Centers for Medicare & Medicaid Services (CMS) Inpatient Standard Analytical Files (IPSAF), patients >65 years with TBI (>1 injury ICD‐10 starting with "S06") were selected. Trauma center levels were linked to the IPSAF file via American Hospital Association Hospital Provider ID and fuzzy‐string matching. Patient variables were compared across trauma center levels. Results: Three hundred forty‐eight thousand eight hundred inpatients (50.4% female; 87.1% white) from 2963 US hospitals were included. Level I/II trauma centers treated 66.9% of patients; non‐trauma centers treated 21.5%. Overall inter‐facility transfer rate was 19.2%; in Level I/II trauma centers transfers‐in represented 23.3% of admissions. Significant TBI (Head AIS ≥3) was present in 70.0%. Most frequent diagnoses were subdural hemorrhage (56.6%) and subarachnoid hemorrhage (30.6%). Neurosurgical operations were performed in 10.9% of patients and operative rates were similar regardless of center level. Total unadjusted mortality for the sample was 13.9%, with a mortality of 8.1% for those who expired in‐hospital, and an additional 5.8% for those discharged to hospice. Medicare payments totaled $4.91B, with the majority (73.4%) going to Level I/II trauma centers. Conclusions: This study fills a gap in TBI research by demonstrating that although the majority of older adult TBI patients in the United States receive care at Level I/II trauma centers, a substantial percentage are managed at other facilities, despite 1 in 10 requiring neurosurgical operation regardless of level of trauma center. This analysis provides preliminary data on the function of regionalized trauma care for older adult TBI care. Future studies assessing the efficacy of early care guidelines in this population are warranted. [ABSTRACT FROM AUTHOR]

Background: Injuries are a leading cause of emergency department (ED) visits among older adults, and individuals with Alzheimer's disease and related dementias (ADRD) may be at particular risk. We compared injury‐related ED use among assisted living (AL) residents with and without ADRD and assessed differences in the risk of injury‐related ED visits among individuals with ADRD residing in ALs with memory care designation versus general AL. Methods: Using Medicare claims, we identified a cohort of fee‐for‐service beneficiaries who lived in AL in 2018 and resided in one of 20 states with site‐specific information on memory care designation (n = 116,754). Outcomes included all injury‐related ED visits and injury‐related ED visits resulting in hospitalization in the calendar year 2018. We fit multilevel models of the association between ADRD and outcomes, adjusting for resident demographic characteristics and chronic conditions, license type characteristics, and AL characteristics, with random intercepts at the AL and license type levels. Among residents with ADRD, we examined whether memory care licensure was associated with injury‐related ED visits. Results: The adjusted risk of injury‐related ED use during the year was 20.1% (95% CI: 19.6%, 20.6%) for residents with ADRD compared to 16.1% for residents without ADRD (95% CI: 15.7%, 16.5%; p < 0.001). The adjusted risk of injury‐related ED use ending in hospitalization was 4.9% (95% CI: 4.6%, 5.1%) for AL residents with ADRD and 3.9% for residents without ADRD (95% CI: 3.8%, 4.1%; p < 0.001). There were no significant differences in injury‐related ED visits between residents with ADRD in ALs with memory care designation and residents in general AL. Conclusions: Injury‐related ED visits are common among AL residents with ADRD and residents in memory care, but residents in memory care AL experienced similar risks of injury as those in general AL. Further research should identify modifiable factors that can prevent injury among AL residents with ADRD. [ABSTRACT FROM AUTHOR]

Introduction: Medication reconciliation, a technique that assists in aligning a care team's understanding of an individual's true medication regimen, is vital to optimize medication use and prevent medication errors. Historically, most medication reconciliation research has focused on institutional settings and transitional care, with comparatively little attention given to medication reconciliation in community settings. To optimize medication reconciliation for community‐dwelling older adults, healthcare professionals and older adults must be engaged in co‐designing processes that create sustainable approaches. Methods: Academic researchers, older adults, and community‐ and health system‐based healthcare professionals engaged in a participatory process to better understand medication reconciliation barriers and co‐design solutions. The initiative consisted of two participatory research approaches: (1) Sparks Innovation Studios, which synthesized professional expertise and opinions, and (2) a Community Consultation Studio with older adults. Input from both groups informed a list of possible solutions and these were ranked based on evaluative criteria of feasibility, person‐centeredness, equity, and sustainability. Results: Sparks Innovation Studios identified a lack of ownership, fragmented healthcare systems, and time constraints as the leading barriers to medication reconciliation. The Community Consultation Studio revealed that older adults often feel dismissed in medical encounters and perceive poor communication with and among providers. The Community Consultation Studio and Sparks Innovation Studios resulted in four highly‐ranked solutions to improve medication reconciliation: (1) support for older adults to improve health literacy and ownership; (2) ensuring medication indications are included on prescription labels; (3) trainings and incentives for front‐line staff in clinic settings to become champions for medication reconciliation; and (4) electronic health record improvements that simplify active medication lists. Conclusion: Engaging community representatives with academic partners in the research process enhanced understanding of community priorities and provided a practical roadmap for innovations that have the potential to improve the well‐being of community‐dwelling older adults.

The article discusses a study on the impact of the coronavirus disease 2019 (COVID-19) pandemic on influenza and infection control practices in U.S. nursing homes. Topics covered include the pandemic's enhancement of infection control practices which may be continued, and of the value of masking, and the improvement of healthcare workers' vaccination via a vaccine champion. Also noted are general infection control knowledge and practices.

Background: The use of a new medication (e.g., potassium supplementation) for managing a drug‐induced adverse event (e.g., loop diuretic‐induced hypokalemia) constitutes a prescribing cascade. However, loop diuretics are often stopped while potassium may be unnecessarily continued (i.e., relic). We aimed to quantify the occurrence of relics using older adults previously experiencing a loop diuretic‐potassium prescribing cascade as an example. Methods: We conducted a prescription sequence symmetry analysis using the population‐based Medicare Fee‐For‐Service data (2011–2018) and partitioned the 150 days following potassium initiation by day to assess the daily treatment scenarios (i.e., loop diuretics alone, potassium alone, combination of loop diuretics and potassium, or neither). We calculated the proportion of patients developing the relic, proportion of person‐days under potassium alone, the daily probability of the relic, and the proportion of patients filling potassium after loop diuretic discontinuation. We also identified the risk factors of the relic. Results: We identified 284,369 loop diuretic initiators who were 8 times more likely to receive potassium supplementation simultaneously or after (i.e., the prescribing cascade), rather than before, loop diuretic initiation (aSR 8.0, 95% CI 7.9–8.2). Among the 66,451 loop diuretic initiators who subsequently (≤30 days) initiated potassium, 20,445 (30.8%) patients remained on potassium after loop diuretic discontinuation, and 9365 (14.1%) patients subsequently filled another potassium supplementation. Following loop diuretic initiation, 4.0% of person‐days were for potassium alone, and daily probability of the relic was the highest after day 90 of loop diuretic initiation (5.6%). Older age, female sex, higher diuretic daily dose, and greater baseline comorbidities were risk factors for the relic, while patients having the same prescriber or pharmacy involved in the use of both medications were less likely to experience the relic. Conclusions: Our findings suggest the need for clinicians to be aware of the potential of relic to avoid unnecessary drug use. [ABSTRACT FROM AUTHOR]

Background: Antiepileptics are commonly prescribed to nursing home residents with Alzheimer's disease and related dementias (ADRD) but there is little scientific support for their use in this population. It is unclear whether different antiepileptics are targeting different indications. Methods: Using the Minimum Data Set and Medicare data, including Part D pharmacy claims, we constructed annual cohorts of residents with ADRD with long‐term stays in nursing homes from 2015 to 2019. For each year, we measured the proportion of residents with ADRD in nursing homes nationwide with at least one antiepileptic prescription. We also measured trends in valproic acid, gabapentin, antipsychotic, and opioid prescribing. Finally, we examined how prescribing rates differed based on whether residents with ADRD had disruptive behaviors or reported pain. Results: Our study sample includes 973,074 persons living with ADRD who had a long‐term stay in a nursing home, which was defined as at least 3 months. The proportion of residents with ADRD with at least one antiepileptic prescription increased from 29.5% in 2015 to 31.3% in 2019, which was driven by increases in the rate of valproic acid and gabapentin prescribing. Conversely, antipsychotic prescribing rates declined from 32.1% to 27.9% and opioid prescribing rates declined from 39.8% to 31.7%. The risk of valproic acid prescribing was 10.9 percentage points higher among residents with ADRD with disruptive behaviors, while the risk of being prescribed gabapentin was 13.9 percentage points higher among residents with ADRD reporting pain. Conclusions: Antiepileptic prescribing among nursing home residents with ADRD is increasing, while antipsychotic and opioid prescribing is declining. Examining antiepileptic prescribing to residents with ADRD who had disruptive behaviors and/or reported pain suggests that two of the most common antiepileptics, valproic acid and gabapentin, are being used in clinically distinct ways. Antiepileptic prescribing of questionable risk–benefit for dementia care warrants further scrutiny. See related editorial by Carnahan et al. in this issue. [ABSTRACT FROM AUTHOR]

The objective of this study was gather pilot data from informal caregivers regarding the potential for a training program to assist current or past caregivers in reentering the job market, and thus offering a pathway to economic resilience. In an effort that could foster a sustainable and competent caregiving market to help meet the needs of an aging America, whether training informal caregivers might help them transition into a paid caregiving or other health service role was explored. Caregivers (N = 55) of a chronically or terminally ill family member or friend in a suburban county near Chicago were interviewed. The interview guide addressed household economic effect of illness, emotional burden, and training program interest. Fifty-six percent of caregivers were interested in training to work outside the home, caring for people in other households, 84% indicated a desire to learn more about health care, and 68% reported a desire to explore job possibilities in health care. Eighty-two percent were experienced in working with an individual aged 50 and older. Informal caregivers' interest in a training program to bolster their qualifications for a role in the healthcare workforce, including the option of a formal caregiver position, supports the demand for such a program. Considering the need for healthcare workers to serve the growing elderly population and the desire of informal caregivers to find gainful employment, these informal caregivers could provide the impetus to invest in informal caregiver training.

Objectives: To examine the effect of the Medicare Annual Wellness Visit (AWV) on the detection of cognitive impairment and on follow‐up cognitive care for older adults. Design: Retrospective matched‐cohort study. Setting: United States. Participants: A 5% random sample of fee‐for‐service Medicare beneficiaries continuously enrolled for 12 months before and after an index ambulatory visit occurring from 2011 to 2013 with no claims evidence of cognitive impairment before index. Measurements: Outcomes include 12‐month post‐index visit claims‐based measurements of cognitive impairment, including new Alzheimer's disease and related dementia (ADRD) diagnoses; medications for ADRD; and cognitive care‐related diagnostic examination such as neurobehavioral testing, brain imaging, and blood tests for thyroid‐stimulating hormone (TSH), serum B12, folate, and syphilis. We also measured changes in burden of anticholinergic medication. Results: There were no clinically relevant differences between the AWV and control groups in the rates of incident ADRD diagnoses (6.16% vs 6.86%, p<.001) and initiation of ADRD medications (1.00% vs 1.08%, p=.15), although there were differences favoring the AWV group in rates of TSH (39.80% vs 28.36%, p<.001), B12 (9.41% vs 6.97%, p<.001), folate (4.76% vs 3.72%, p<.001), and neurobehavioral (0.75% vs 0.55%, p<.001) testing. Conclusions: Although the AWV is correlated with an increase in some measures of cognitive care, such as laboratory testing for reversible causes of cognitive impairment, it does not appear to substantially increase recognition of undetected ADRD.

Objectives: To estimate food insecurity prevalence and develop a statistical prediction model for food insecurity. Design: Retrospective cohort study. Setting: Kaiser Permanente Colorado. Participants: Adult members who completed a pre‐Medicare Annual Wellness Visit survey. Measurements: Food insecurity was assessed using a single screening question. Sociodemographic and clinical characteristics from electronic health records and self‐reported characteristics from the survey were used to develop the prediction model. Results: Of 130,208 older adult members between January 2012 and December 2015, 50,097 (38.5%) completed food insecurity screening, 2,859 of whom (5.7% of respondents) reported food insecurity. The prevalence of food insecurity was 10.0% or greater among individuals who were black or Hispanic, had less than high school education, had Medicaid insurance, were extremely obese, had poor health status or quality of life, had depression or anxiety, had impairments in specific activities of daily living, had other nutritional risk factors, or were socially isolated (all p<.001). A multivariable model based on these and other characteristics showed moderate discrimination (c‐statistic = 0.74) between individuals with food insecurity and those without and 14.3% of individuals in the highest quintile of risk reported food insecurity. Conclusion: Food insecurity is prevalent even in older adults with private‐sector healthcare coverage. Specific individual characteristics, and a model based on those characteristics, can identify older adults at higher risk of food insecurity. System‐level interventions will be necessary to connect older adults with community‐based food resources. [ABSTRACT FROM AUTHOR]

Objectives To determine whether elderly veterans with posttraumatic stress disorder ( PTSD) and dementia are more likely to be prescribed second-generation antipsychotics ( SGAs) than those with PTSD alone. Design National serial cross-sectional study. Setting Veterans Health Affairs inpatient and outpatient settings. Participants Veterans aged 65 and older with PTSD (excluding schizophrenia or bipolar disorder) with or without concomitant dementia who received care from the Veterans Health Administration between 2003 and 2010 were identified using International Classification of Diseases, Ninth Revision, codes (N = 93,068; 11.1% with dementia). Measurements Trends in SGA prescribing and odds of being prescribed an SGA were determined using a multivariable logistic regression model adjusted for clinical, sociodemographic, and geographic covariates. Results Between 2004 and 2009, SGA prescribing declined annually from 7.0% to 5.1% of elderly veterans with PTSD without dementia and 13.2% to 8.9% in those with dementia; findings over time consistently indicated that veterans with PTSD and dementia had at least twice the odds of being prescribed an SGA as those without PTSD (odds ratios 2.03 (95% confidence interval ( CI) = 1.82-2.26) to 2.33 (95% CI = 2.10-2.58). Conclusion Although the prescribing of SGAs to elderly veterans with PTSD has decreased, prescribing an SGA to those with dementia remained consistently higher than for those with PTSD alone and is problematic given the high prevalence of medical comorbidities in this aging population coupled with the lack of compelling evidence for effectiveness of SGAs in individuals with dementia.

Objectives To estimate the number of caregivers providing assistance to community-dwelling older persons with and without dementia and with or without substantial disability; to describe the characteristics of caregivers and care recipients in these groups; to characterize the health-related tasks that caregivers provide; and to estimate associations between the numbers of tasks and caregiver burden. Design Nationally representative surveys of caregivers and older adults in the United States. Setting 2011 National Health and Aging Trends Study and National Study of Caregiving. Participants Community-dwelling older adults and their family caregivers, who were selected on the basis of having assisted with mobility, self-care, household activities, transportation, or medical tasks. Measurements Caregiver burden (emotional, physical, financial difficulties) and restrictions on social participation. Results Although much larger proportions of older adults with dementia and disability (98.4%, n = 1.0 million) and dementia but not disability (95.5%, n = 1.3 million) received caregiving assistance, the largest absolute number of individuals receiving assistance were older adults without dementia or disability (4.0 million). Within each caregiver group, caregivers provided assistance with at least one task across domains of activity of daily living and instrumental activity of daily living-related assistance (>98%), health systems logistics (>70%), and health management (>50%). There was a significant linear association between number of tasks provided and risk of burden in virtually all caregiver groups and domains of assistance. Conclusion Caregivers of care recipients without dementia or disability accounted for the largest absolute number of helpers. These caregivers, similar to caregivers of care recipients with dementia or disability, delivered a broad spectrum of health-related tasks and experienced caregiver burden and restrictions on social participation. Findings support the need for interventions that address the needs of caregivers who have not typically been defined as high risk. [ABSTRACT FROM AUTHOR]

Objectives To examine caregiver factors associated with unmet needs for care of older adults. Design Population-based surveys of caregivers and older adult care recipients in the United States in 2011. Setting 2011 National Health and Aging Trends Study and National Study of Caregiving. Participants Family caregivers (n = 1,996) of community-dwelling older adults with disabilities (n = 1,366). Measurements Disabled care recipient reports of unmet needs for care in the past month with activities of daily living ( ADLs; e.g., wet or soiled clothing), mobility (e.g., have to stay inside), or instrumental activities of daily living ( IADLs; e.g., medication errors). Caregiver reported sociodemographic characteristics, caregiving intensity and tasks performed, health, and psychosocial effects. Results Of the care recipients, 44.3% reported at least one unmet need for care in the past month (38.2% ADL related, 14.6% IADL related). Younger caregivers, caregiving sons, caregivers not living with care recipients, and having supplemental paid caregivers were associated with more unmet needs. Caregivers with recipients reporting two or more unmet needs were more likely to spend more than 100 hours per month caregiving, help with skin care and wounds, report caregiving as emotionally and physically difficult, and report restricted participation in valued activities (all P < .001). Conclusion Unmet ADL needs are prevalent among older adults with family caregivers. Caregivers experiencing high levels of burden, stress, and negative physical and psychosocial impacts may provide substandard or poor care to older adults, which may be a risk factor for neglect. Clinicians caring for disabled older adults should assess their unmet needs and the capacity of caregivers to address them. [ABSTRACT FROM AUTHOR]

Objectives To perform an economic evaluation of a primary care-based physical activity counseling intervention that improved physical activity levels and rapid gait speed in older veterans. Design Secondary objective of randomized trial that assessed the effect of exercise counseling (relative to usual care) on physical performance, physical activity, function, disability, and medical resource use and cost. Setting Veterans Affairs Medical Center, Durham, North Carolina. Participants Male veterans aged ≥70 years (n = 398). Intervention An experienced health counselor provided baseline in-person exercise counseling, followed by telephone counseling at 2, 4, and 6 weeks, and monthly thereafter through one year. Each participant's primary care physician provided initial endorsement of the intervention, followed by monthly automated telephone messages tailored to the patient. Individualized progress reports were mailed quarterly. Measurements Intervention costs were assessed. Health care resource use and costs were estimated from enrollment through one year follow-up. The incremental cost of achieving clinically significant changes in major trial endpoints was calculated. Results The total direct cost of the intervention per participant was $459, 85% of which was counselor effort. With overhead, program cost totaled $696 per participant. Medical costs during follow-up reached $10,418 with the intervention, versus $12,052 with usual care (difference = −$1,634 (95% confidence interval = −$4,683 to $1,416; P = .29)). Expressed in terms of short-term clinical outcomes, the intervention cost $4,971 per additional patient reaching target exercise levels, or $4,640 per patient achieving a clinically significant change in rapid gait speed. Conclusion Improvements in physical activity and rapid gait speed in the physical activity counseling group were obtained at a cost that represents a small fraction of patients' annual health care costs.

Objectives The Meaningful Use initiative has made nearly $30 billion available through incentive programs to encourage provider adoption and use of electronic health records. The objective of this study was to evaluate the impact of outpatient physicians' participation in Meaningful Use on the quality of care provided to Medicare fee-for-service (FFS) enrollees . Design Retrospective cohort study. Setting One hundred percent inpatient and outpatient Medicare FFS claims covering the period January 2010 through December 2012. Participants 303,110 Medicare FFS enrollees from New York State. Measurements Hospitalizations and emergency department (ED) visits for ambulatory care sensitive conditions (ACSCs), diabetic retinopathy screening, diabetic nephropathy screening, colorectal cancer screening, and influenza vaccinations. Results Physician participation in the Meaningful Use initiative was not associated with reductions in ACSC-related hospitalizations (0.0 percentage points, 95% confidence interval (CI): 0.0-0.1) or ED visits (0.0 percentage points, 95% CI: 0.0-0.1) relative to the comparison group. Meaningful Use participation was associated with higher odds of colorectal cancer screening (odds ratio (OR): 1.2, 95% CI: 1.1-1.4) relative to the comparison group, but not for diabetic retinopathy screening (OR: 1.1, 95% CI: 1.0-1.2), diabetic nephropathy screening (OR: 1.0, 95% CI: 0.8-1.2), or influenza vaccinations (OR: 1.1, 95% CI: 1.0-1.2). Similar results were found in secondary analyses of dually-eligible beneficiaries participating in both Medicare and Medicaid. Conclusion Physician participation in Meaningful Use was not associated with substantial improvements on six quality measures. [ABSTRACT FROM AUTHOR]

Objectives To derive lean mass cutpoints based on a less-conservative Foundation for the National Institutes of Health ( FNIH) Sarcopenia Project Weakness cutpoint for grip strength (WeakI) and to assess their agreement with European Working Group on Sarcopenia in Older People ( EWGSOP) and prediction of incident slow walking and mortality. Design Longitudinal analysis. Setting Baltimore Longitudinal Study of Aging. Participants Individuals aged 65 and older (287 men, 258 women) with 2 to 10 years of follow-up. Measurements Weakness was determined according to handgrip strength using a hand dynamometer, appendicular lean mass ( ALM) using dual-energy X-ray absorptiometry, and walking speed according to 6-m usual pace walk speed. Analyses were performed using classification and regression tree analysis, Cohen's kappa, and Cox models. Results Cutpoints derived from WeakI for ALM ( ALMI) were less than 21.4 kg in men and less than 14.1 kg in women and for ALM adjusted for body mass index ( ALM/ BMII) were less than 0.725 in men and less than 0.591 in women. Kappas with EWGSOP were 0.65 for men and 0.75 for women for ALMI and 0.34 for men and 0.47 for women for ALM/ BMII. Men with WeakI + ALMI were twice as likely to develop slow walking as those not weak with normal ALMI (Hazard ratio (HR) = 2.44, 95% confidence interval (CI) = 1.02-5.82). Under EWGSOP, men with weakness and low RALM were almost 3 times as likely to develop slow walking as those not weak with normal RALM (HR = 2.91, 95% CI = 1.11-7.62). Neither approach predicted incident slow walking in women. Conclusion The ALMI cutpoints agree with EWGSOP and predict slow walking in men. Future studies should explore sex differences in the relationship between body composition and physical function and the effect of change in muscle mass on muscle strength and physical function.

Objectives Evidence suggests vitamin D deficiency is associated with developing frailty. However, cardiometabolic factors are related to both conditions and may confound and/or mediate the vitamin D-frailty association. We aimed to determine the association of vitamin D concentration with incidence of frailty, and the role of cardiometabolic diseases (cardiovascular disease, diabetes, hyperlipidemia, hypertension) in this relationship. Design Prospective longitudinal cohort study (7 visits from 1994-2008). Setting Baltimore, Maryland. Participants Three hundred sixty-nine women from the Women's Health and Aging Study II aged 70-79 years, free of frailty at baseline. Measurements Serum circulating 25-hydroxyvitamin D (25[ OH]D) concentration was assessed at baseline and categorized as: <10; 10-19.9; 20-29.9; and ≥30 ng/ mL. Frailty incidence was determined based on presence of three or more criteria: weight loss, low physical activity, exhaustion, weakness, and slowness. Cardiometabolic diseases were ascertained at baseline. Analyses included Cox regression models adjusted for key covariates. Results Incidence rate of frailty was 32.2 per 1,000 person-years in participants with 25( OH)D < 10 ng/ mL, compared to 12.9 per 1,000 person-years in those with 25( OH)D ≥ 30 ng/ mL (mean follow-up = 8.5 ± 3.7 years). In cumulative incidence analyses, those with lower 25( OH)D exhibited higher frailty incidence, though differences were non-significant ( P = .057). In regression models adjusted for demographics, smoking, and season, 25( OH)D < 10 ng/ mL (vs ≥30 ng/ mL) was associated with nearly three-times greater frailty incidence (hazard ratio ( HR) = 2.77, 95% CI = 1.14, 6.71, P = .02). After adjusting for BMI, the relationship of 25( OH)D < 10 ng/ mL (vs ≥30 ng/ mL) with incident frailty persisted, but was attenuated after further accounting for cardiometabolic diseases ( HR = 2.29, 95% CI = 0.92, 5.69, P = .07). Conclusion Low serum vitamin D concentration is associated with incident frailty in older women; interestingly, the relationship is no longer significant after accounting for the presence of cardiometabolic diseases. Future studies should explore mechanisms to explain this relationship. [ABSTRACT FROM AUTHOR]

Objectives To determine effects of Sit 'N' Fit Chair Yoga, compared to a Health Education program ( HEP), on pain and physical function in older adults with lower extremity osteoarthritis ( OA) who could not participate in standing exercise. Design Two-arm randomized controlled trial. Setting One HUD senior housing facility and one day senior center in south Florida. Participants Community-dwelling older adults (N = 131) were randomly assigned to chair yoga (n = 66) or HEP (n = 65). Thirteen dropped after assignment but prior to the intervention; six dropped during the intervention; 106 of 112 completed at least 12 of 16 sessions (95% retention rate). Interventions Participants attended either chair yoga or HEP. Both interventions consisted of twice-weekly 45-minute sessions for 8 weeks. Measurements Primary: pain, pain interference; secondary: balance, gait speed, fatigue, functional ability measured at baseline, after 4 weeks of intervention, at the end of the 8-week intervention, and post-intervention (1 and 3 months). Results The chair yoga group showed greater reduction in pain interference during the intervention ( P = .01), sustained through 3 months ( P = .022). WOMAC pain ( P = .048), gait speed ( P = .024), and fatigue ( P = .037 ) were improved in the yoga group during the intervention ( P = .048) but improvements were not sustained post intervention. Chair yoga had no effect on balance. Conclusion An 8-week chair yoga program was associated with reduction in pain, pain interference, and fatigue, and improvement in gait speed, but only the effects on pain interference were sustained 3 months post intervention. Chair yoga should be further explored as a nonpharmacologic intervention for older people with OA in the lower extremities. Trial Registration: ClinicalTrials.gov: NCT02113410.

Objectives To determine the association between homebound status and mortality. Design Cross-sectional. Setting Annual, in-person interviews. Participants A nationally representative sample of community-dwelling, Medicare beneficiaries aged 65 and older enrolled in the National Health and Aging Trends Study between 2011 and 2013 (N = 6,400). Measurements Two-year mortality and prevalence of homebound status in the year before death are described using three categories of homebound status: homebound (never or rarely left home in the last month), semihomebound (left home with assistance, needed help or had difficulty), and nonhomebound (left home without help or difficulty). Results In unadjusted analyses, 2-year mortality was 40.3% in homebound participants, 21.3% in those who were semihomebound and 5.8% in those who were nonhomebound. Homebound status was associated with greater 2-year mortality, adjusted for sociodemographic characteristics, comorbidities, and functional status (hazard ratio = 2.08; 95% confidence interval = 1.63-2.65, P < .001). Half of older community-dwelling Medicare beneficiaries were homebound in the year before death. Conclusion Homebound status is associated with greater risk of death independent of functional impairment and comorbidities. To improve outcomes for homebound older adults and the many older adults who will become homebound in the last year of life, providers and policymakers need to extend healthcare services from hospitals and clinics to the homes of vulnerable individuals.

Objectives To describe the incidence of cardiovascular risk factors, or race-related disparities in incidence, across the age spectrum in adults. Design Longitudinal cohort. Setting National sample. Participants Community-dwelling black and white adults recruited between 2003 and 2007. Measurements Incident hypertension, diabetes mellitus, dyslipidemia and atrial fibrillation over 10 years of follow-up in 10,801 adults, stratified according to age (45-54, 55-64, 65-74, ≥75). Results There was no evidence ( P ≥ .68) of an age-related difference in the incidence of hypertension for white men (average incidence 38%), black men (48%), or black women (54%), although for white women incidence increased with age (45-54, 27%; ≥75, 40%). Incidence of diabetes mellitus was lower at older ages for white men (45-54, 15%; ≥75, 8%), black men (45-54, 29%; ≥75, 13%), and white women (45-54, 11%; ≥75, 4%), although there was no evidence ( P = .11) of age-related changes for black women (average incidence 21%). For dyslipidemia, incidence for all race-sex groups was approximately 20% for aged 45 to 54 but approximately 30% for aged 54 to 64 and 65 to 74 and approximately 22% for aged 75 and older. Incidence of atrial fibrillation was low at age 45 to 54 (<5%) but for aged 75 and older was approximately 20% for whites and 11% for blacks. The incidence of hypertension, diabetes mellitus, and dyslipidemia was higher in blacks across the age spectrum but lower for atrial fibrillation. Conclusion Incidence of risk factors remains high in older adults. Blacks have a higher incidence of hypertension, diabetes mellitus, and dyslipidemia after age 45, underscoring the ongoing importance of prevention of all three conditions in mid- to later life.

Objectives To determine whether subjective poor sleep prospectively increases functional limitations and incident disability in a national sample of adults living in the United States. Design Prospective cohort. Setting Longitudinal Survey of Midlife Development in the United States ( MIDUS). Participants Young, middle-aged, and older men and women (aged 24-75) surveyed in 1995/96 ( MIDUS 1) and followed up in 2004-06 ( MIDUS 2). Complete data were available for 3,620 respondents. Measurements Data were from telephone interviews and self-administered questionnaires. Participant reported chronic sleep problems within the prior month; functional limitations were assessed using the Functional Status Questionnaire. Demographic (age, sex, race), socioeconomic (educational attainment), health (chronic conditions, depression), and health behavior (obesity, smoking) covariates were assessed to reduce potential confounding. Results Approximately 11% of the sample reported chronic sleep problems at both MIDUS waves. Average number of activity of daily living ( ADL) and instrumental activity of daily living ( IADL) limitations increased significantly between MIDUS 1 ( ADL limitations: 0.06; IADL limitations: 0.95) and MIDUS 2 ( ADL limitations: 0.15; IADL limitations: 1.6; P < .001). Adjusted regression models estimating change in ADL scores showed that chronic sleep problems at MIDUS 1 predicted significantly greater increases in ADL (incident rate ratio ( IRR) = 1.55, P < .001) and IADL ( IRR = 1.28, P < .001) limitations. In those with no functional limitations at baseline, logistic regression models showed that chronic sleep problems significantly increased the odds of incident ADL (odds ratio ( OR) = 2.33, 95% confidence interval ( CI) = 1.68-3.24, P < .001) and IADL ( OR = 1.70, 95% CI = 1.21-2.42, P = .002) disability. Conclusion Reports of chronic sleep problems predicted greater risk of onset of and increases in functional limitations 9 to 10 years later. Poor sleep may be a robust and independent risk factor for disability in adults of all ages. [ABSTRACT FROM AUTHOR]

Objectives To describe the prevalence of discrepancies between medication lists that referring providers and home healthcare ( HH) nurses create. Design The active medication list from the hospital at time of HH initiation was compared with the HH agency's plan of care medication list. An electronic algorithm was developed to compare the two lists for discrepancies. Setting Single large hospital and HH agency in the western United States. Participants Individuals referred for HH from the hospital in 2012 (N = 770, 96.3% male, median age 71). Measurements Prevalence was calculated for discrepancies, including medications missing from one list or the other and differences in dose, frequency, or route for medications contained on both lists. Results Participants had multiple medical problems (median 16 active problems) and were taking a median of 15 medications (range 1-93). Every participant had at least one discrepancy; 90.1% of HH lists were missing at least one medication that the referring provider had prescribed, 92.1% of HH lists contained medications not on the referring provider's list, 89.8% contained medication naming errors. 71.0% contained dosing discrepancies, and 76.3% contained frequency discrepancies. Conclusion Discrepancies between HH and referring provider lists are common. Future work is needed to address possible safety and care coordination implications of discrepancies in this highly complex population. [ABSTRACT FROM AUTHOR]

Objectives To describe the epidemiology of indwelling urinary catheter use in nursing homes ( NHs). Design Observational cohort study. Setting A purposeful sampling strategy was used to identify a diverse sample of 28 Connecticut NHs, defined in terms of ownership, quality ratings, and bed size. Participants Long-stay (>100 days) residents of study NHs with an indwelling urinary catheter present at any time over a 1-year period. Measurements Duration of catheter use was determined, and indications for catheter placement were documented. Indications considered appropriate included urinary retention or outlet obstruction, pressure ulcer (Stage 3 or 4 with risk of contamination by urine), hospice care, and need for accurate measurement of input and output. During quarterly follow-up assessments, whether the catheter was still in place or had been removed for any reason other than routine maintenance was determined. Results The overall rate of any urinary catheter use per 100 resident-beds over a 1-year period was 4.8 (range 1.0-9.9, median 5.1). Of the 228 residents meeting eligibility criteria, a documented indication for the catheter was present in the NH record for 195 (86%). Of those with a documented indication, 99% (n = 193) had one or more indications deemed appropriate, including urinary retention (83%), pressure ulcer (21%), hospice care (10%), and need for accurate measurement of input and output (6%). The urinary catheter was removed at some point during the period of observation in 49% (n = 111) of participants; those with a shorter duration of catheter use before study enrollment were more likely to have the catheter removed during the follow-up period. Of the 111 residents who had the catheter removed, 58 (52.3%) had it reinserted at some point during follow-up. Conclusion These findings suggest that indwelling urinary catheter use in long-stay NH residents is uncommon and generally appropriate and that efforts to improve catheter care and outcomes should extend beyond a singular focus on reducing use.

Objectives To investigate the association between sociodemographic and economic factors and the presence of simple home modifications ( HMs) among older adults in the United States. Design Cross-sectional. Setting National Health and Aging Trends Study (2011, Round 1). Participants Community-dwelling Medicare enrollees aged 65 and older (N = 6,628). Measurements The primary dependent variable was the reported presence or absence of simple HMs (grab bars in the shower or near the toilet, shower seats, raised toilet seats). Results Of the individuals sampled, 60.7% reported having at least one HM of interest. Black (odds ratio ( OR) = 0.79, 95% confidence interval ( CI) = 0.68-0.91) and Hispanic ( OR = 0.60, 95% CI = 0.45-0.78) respondents were less likely than white, non-Hispanic respondents to have HMs. Those with more education (high school graduate: OR = 1.20, 95% CI = 1.01-1.42; >high school: OR = 1.36, 95% CI = 1.14-1.62) and larger social networks (≥4 people; OR = 1.46, 95% CI = 1.12-1.89) were more likely to have at least one HM, whereas being divorced ( OR = 0.57, 95% CI = 0.43-0.74) was associated with lower likelihood. Income ( OR = 1.01, 95% CI = 0.97-1.05), Medicaid enrollment ( OR = 0.98, 95% CI = 0.77-1.25), and living alone ( OR = 1.02, 95% CI = 0.85-1.23) were not significantly associated with the presence of HMs. Conclusion Minorities, individuals with less education, and those with less social support are less likely to have HMs. Awareness of these disparities and the shortcomings of the HM delivery system is important to clinicians and policy-makers who seek to prevent falls and facilitate aging in place for all older Americans.

Objectives To determine the prevalence of end-of-life ( EOL) conversations with older adults. Design National Health and Aging Trends Study ( NHATS), a prospective, longitudinal survey of Medicare beneficiaries. Setting Nationally representative. Participants A sample drawn from Wave 2 of the NHATS. Measurements The main outcome was the report of an EOL planning discussion, based upon the participant's response to the question 'Have you talked to anyone about the types of medical treatment you would want or not want if you became seriously ill in the future?' Results Sixty-one percent of the sample (n = 1,993 individuals, weighted n = 11,123,910) responded that they had discussed EOL treatment preferences with someone. In multivariate regression, factors associated with reporting an EOL discussion included being younger (adjusted odds ratio ( AOR) = 1.70, 95% confidence interval ( CI) = 1.17-2.47), having more education (high school degree: AOR = 1.45, 95% CI = 1.02-2.07; some college: AOR = 2.03, 95% CI = 1.40-2.95), and having multiple chronic conditions ( AOR = 1.25, 95% CI = 1.01-1.55). Black race was associated with lower odds of reporting a discussion ( AOR = 0.46, 95% CI = 0.33-0.65). Conclusion Forty percent of a nationally representative sample of Medicare beneficiaries had not discussed their preferences regarding EOL medical treatment. Promoting these conversations in clinical and nonclinical settings will be important to ensure that health care is delivered to individuals in a person-centered manner. [ABSTRACT FROM AUTHOR]

Objectives To evaluate the associations between a broad array of cardiorespiratory and noncardiorespiratory impairments and dyspnea in older persons. Design Cross-sectional. Setting Cardiovascular Health Study. Participants Community-dwelling persons (N = 4,413; mean age 72.6, 57.1% female, 4.5% African American, 27.2% 1)), maximal inspiratory pressure (respiratory muscle strength), echocardiography, ankle-brachial index, blood pressure, whole-body muscle mass (bioelectrical impedance), single chair stand (lower extremity function), grip strength, serum hemoglobin and creatinine, Center for Epidemiologic Studies Depression Scale ( CES-D), Mini-Mental State Examination, medication use, and body mass index ( BMI). Results In a multivariable logistic regression model, impairments that had strong associations with moderate to severe dyspnea were FEV1 less than the lower limit of normal (adjusted odds ratio ( aOR) = 2.88, 95% confidence interval ( CI) = 2.37-3.49), left ventricular ejection fraction less than 45% ( aOR = 2.12, 95% CI = 1.43, 3.16), unable to perform a single chair stand ( aOR = 2.10, 95% CI = 1.61-2.73), depressive symptoms ( CES-D score ≥16; aOR = 2.02, 95% CI = 1.26-3.23), and obesity ( BMI ≥30; aOR = 2.07, 95% CI = 1.67-2.55). Impairments with modest but still statistically significant associations with moderate to severe dyspnea included respiratory muscle weakness, diastolic cardiac dysfunction, grip weakness, anxiety symptoms, and use of cardiovascular and psychoactive medications ( aORs = 1.31-1.71). Conclusion In community-dwelling older persons, several cardiorespiratory and noncardiorespiratory impairments were significantly associated with moderate to severe dyspnea, akin to a multifactorial geriatric health condition.

Objectives To determine the prevalence and outcomes of breathlessness in older Americans. Setting Community-dwelling older adults. Participants Individuals aged 70 and older in the nationally representative Health and Retirement Study (2008, follow-up through 2012) (N = 3,671; mean age 78). Measurements Breathlessness was assessed by asking the question, 'How often do you become short of breath while awake?' Responses of often or sometimes were considered to represent a level of breathlessness sufficient to warrant clinical attention. The prevalence of breathlessness is described overall and in subpopulations, then rates of associated symptoms, well-being, and health services use of participants who were breathless are compared with rates of those who were not. The risk of decline in activities of daily living ( ADLs) and death through 2012 was estimated by creating a multivariable Cox proportional hazards model, adjusting for age, sex, race and ethnicity, and education. Results Twenty-five percent of participants reported breathlessness. The prevalence of breathlessness was higher in certain subpopulations: chronic lung disease (63%), multimorbidity (≥2 chronic conditions) (45%), current smokers (38%), heart disease (36%), obesity (body mass index ≥30.0 kg/m2) (33%), and education less than high school (32%). Breathlessness was associated with higher rates of depression, anxiety, and severe fatigue; lower ratings of well-being; and higher rates of clinic and emergency department visits and hospitalizations (all P < .001). Breathlessness predicted ADL decline over 5 years (adjusted hazard ratio ( aHR) = 1.43, 95% confidence interval ( CI) = 1.22-1.68) and death ( aHR 1.62, 95% CI = 1.32-2.02). Conclusion One in four adults aged 70 and older in the United States experiences breathlessness, which is associated with lack of well-being, greater health services use, and a 40% greater risk of worsened function and 60% greater risk of death over the next 5 years.

Objectives To understand the perceived preparedness of frontline nurses (registered nurses ( RNs), licensed practical nurses ( LPNs)), unit nurse managers, and skilled nursing facility ( SNF) administrators in providing care for residents with peripherally inserted central catheters ( PICCs) in SNFs. Design Exploratory, qualitative pilot study. Setting Two community based SNFs. Participants Residents with PICCs, frontline nurses ( RNs, LPNs), unit nurse managers, and SNF administrators. Methods Over 36 weeks, 56 residents with PICCs and their nurses were observed and informally interviewed, focusing on PICC care practices and documentation. In addition, baseline PICC data were collected on placement indication (e.g., antimicrobial administration), placement setting (hospital vs SNF), and dwell time. Focus groups were then conducted with frontline nurses and unit nurse managers, and semistructured interviews were conducted with SNF administrators to evaluate perceived preparedness for PICC care. Data were analyzed using a descriptive analysis approach. Results Variations in documentation were observed during weekly informal interviews and observations. Differences were noted between resident self-reported PICC concerns (quality of life) and those described by frontline nurses. Deficiencies in communication between hospitals and SNFs with respect to device care, date of last dressing change, and PICC removal time were also noted. During focus group sessions, perceived inadequacy of information at the time of care transitions, limited availability of resources to care for PICCs, and gaps in training and education were highlighted as barriers to improving practice and safety. Conclusion Practices for PICC care in SNFs can be improved. Multimodal strategies that enhance staff education, improve information exchange during care transitions, and increase resource availability in SNFs appear necessary to enhance PICC care and safety.

Objectives This study examined potential barriers to mental healthcare use of older adults from diverse ethnic and racial backgrounds. Design Data were obtained from the 2007, 2009, 2011-12, and 2013-14 California Health Interview Survey ( CHIS), a population-based survey representative of California's noninstitutionalized population. Participants The total sample consisted of 75,324 non-Hispanic white ( NHW), 6,600 black, 7,695 Asian and Pacific Islander ( API), and 4,319 Hispanic adults aged 55 and older. Results Results from logistic regression analyses that controlled for multiple demographic and health status characteristics revealed ethnic and racial differences in reasons for not seeking treatment and for terminating treatment. Specifically, API and Hispanic adults had greater odds than NHWs of endorsing feeling uncomfortable talking to a professional as a reason for not seeking treatment. Hispanic respondents had lower odds of endorsing concerns about someone finding out than APIs, and APIs and blacks had significantly greater odds of endorsing this concern as a reason for not seeking treatment than NHWs. When asked about reasons for no longer receiving treatment, all respondents, irrespective of race or ethnicity, endorsed that they no longer needed treatment as the most frequent reason for terminating treatment, although specific ethnic and racial differences emerged with respect to perceptions of not getting better, lack of time or transportation, and lack of insurance coverage as reasons for no longer seeking treatment. Conclusion Understanding how barriers to mental health treatment differ for older adults from diverse ethnic and racial backgrounds is an important step toward designing interventions to overcome these obstacles and improve mental health outcomes.

Objectives To inform the development of a data-driven measure of quality care for individuals with multiple chronic conditions ( MCCs) derived from an electronic health record ( EHR). Design Qualitative study using focus groups, interactive webinars, and a modified Delphi process. Setting Research department within an integrated delivery system. Participants The webinars and Delphi process included 17 experts in clinical geriatrics and primary care, health policy, quality assessment, health technology, and health system operations. The focus group included 10 individuals aged 70-87 with three to six chronic conditions selected from a random sample of individuals aged 65 and older with three or more chronic medical conditions. Measurements Through webinars and the focus group, input was solicited on constructs representing high-quality care for individuals with MCCs. A working list was created of potential measures representing these constructs. Using a modified Delphi process, experts rated the importance of each possible measure and the feasibility of implementing each measure using EHR data. Results High-priority constructs reflected processes rather than outcomes of care. High-priority constructs that were potentially feasible to measure included assessing physical function, depression screening, medication reconciliation, annual influenza vaccination, outreach after hospital admission, and documented advance directives. High-priority constructs that were less feasible to measure included goal setting and shared decision-making, identifying drug-drug interactions, assessing social support, timely communication with patients, and other aspects of good customer service. Lower-priority domains included pain assessment, continuity of care, and overuse of screening or laboratory testing. Conclusion High-quality MCC care should be measured using meaningful process measures rather than outcomes. Although some care processes are currently extractable from electronic data, capturing others will require adapting and applying technology to encourage holistic, person-centered care.

Objectives To compare the ability of the commonly used Women's Health Initiative ( WHI) and Cardiovascular Health Study ( CHS) frailty phenotypes to predict falls, hip fracture, and death in WHI Clinical Trial participants aged 65 and older. Design Longitudinal cohort study. Setting WHI Clinical Trial. Participants Participants with data for WHI and CHS frailty phenotypes (N = 3,558). Measurements Frailty was operationally defined in the CHS as the presence of three or more of weight loss, poor energy, weakness, slowness, and low physical activity. WHI operationalized frailty similarly but with the RAND-36 physical function scale substituted for slowness and weakness ( RAND-36 physical function scale score <13 = 2 points, 13-78 = 1 point, >78 = 0 points). Frailty was defined as a summary score of 3 or greater, prefrailty as a score of 2 or 1, and nonfrailty as a score of 0. Outcomes were modeled using Cox regression. Harrell C-statistics were compared for models containing alternative instruments. Results Approximately 5% of participants were frail based on the CHS or WHI phenotype. The WHI frailty phenotype was associated with higher rates of falls (hazard ratio ( HR) = 1.48, P = .003), hip fracture ( HR = 1.87, P = .04), and death ( HR = 2.32, P < .001). Comparable HRs in CHS-phenotype frail women were 1.32 ( P = .04), 1.08 ( P = .83), and 1.91 ( P < .001), respectively. Harrell C-statistics revealed marked but insignificant differences in predicting abilities between CHS and WHI phenotype models ( P > .50 for all). Conclusion The WHI phenotype, which does not require direct measurements of physical performance, might offer a practical advantage for epidemiological and clinical needs. [ABSTRACT FROM AUTHOR]

Objectives To develop a prediction index for 1-year mortality after hip fracture in older adults that includes predictors from a wide range of domains. Design Retrospective cohort study. Settings Health and Retirement Study ( HRS). Participants HRS participants who experienced hip fracture between 1992 and 2010 as identified according to Medicare claims data (N = 857). Measurements Outcome measure was death within 1 year of hip fracture. Predictor measures were participant demographic characteristics, socioeconomic status, social support, health, geriatric symptoms, and function. Variables independently associated with 1-year mortality were identified, and best-subsets regression was used to identify the final model. The selected variables were weighted to create a risk index. The index was internally validated using bootstrapping to estimate model optimism. Results Mean age at time of hip fracture was 84, and 76% of the participants were women. There were 235 deaths (27%) during the 1-year follow up. Five predictors of mortality were included in the final model: aged 90 and older (2 points), male sex (2 points), congestive heart failure (2 points), difficulty preparing meals (2 points), and not being able to drive (1 point). The point scores of the index were associated with 1-year mortality, with 0 points predicting 10% risk and 7 to 9 points predicting 66% risk. The c-statistic for the final model was 0.73, with an estimated optimism penalty of 0.01, indicating very little evidence of overfitting. Conclusion The prognostic index combines demographic, comorbidity, and function variables and can be used to differentiate between individuals at low and high risk of 1-year mortality after hip fracture.

Objectives To determine to what extent demographic, social support, socioeconomic, geographic, medical, and End-of-Life ( EOL) planning factors explain racial and ethnic variation in Medicare spending during the last 6 months of life. Design Retrospective cohort study. Setting Health and Retirement Study ( HRS). Participants Decedents who participated in HRS between 1998 and 2012 and previously consented to survey linkage with Medicare claims (N = 7,105). Measurements Total Medicare expenditures in the last 180 days of life according to race and ethnicity, controlling for demographic factors, social supports, geography, illness burden, and EOL planning factors, including presence of advance directives, discussion of EOL treatment preferences, and whether death had been expected. Results The analysis included 5,548 (78.1%) non-Hispanic white, 1,030 (14.5%) non-Hispanic black, and 331 (4.7%) Hispanic adults and 196 (2.8%) adults of other race or ethnicity. Unadjusted results suggest that average EOL Medicare expenditures were $13,522 (35%, P < .001) more for black decedents and $16,341 (42%, P < .001) more for Hispanics than for whites. Controlling for demographic, socioeconomic, geographic, medical, and EOL-specific factors, the Medicare expenditure difference between groups fell to $8,047 (22%, P < .001) more for black and $6,855 (19%, P < .001) more for Hispanic decedents than expenditures for non-Hispanic whites. The expenditure differences between groups remained statistically significant in all models. Conclusion Individuals-level factors, including EOL planning factors do not fully explain racial and ethnic differences in Medicare spending in the last 6 months of life. Future research should focus on broader systemic, organizational, and provider-level factors to explain these differences. [ABSTRACT FROM AUTHOR]

Although advance care planning ( ACP) is associated with better care at the end of life, better quality of death, and less psychological distress in survivors, ethnic disparities in ACP completion rates have been documented and may be attributable to lack of knowledge about ACP or differences in cultural values and preferences. Despite rapid increases in the size of the Asian-American population, little is known about ACP preferences of Chinese Americans. The purpose of this study is to explore the knowledge, attitudes, and preferences of older Chinese Americans toward ACP. Focus groups with Chinese older adults (n = 34) were conducted in Mandarin, Cantonese, and English, and transcripts were analyzed using a grounded theory approach. Identified themes included knowledge and experience with ACP and end-of-life care options, health as a factor in timing of ACP and communication, and communication of end-of-life care preferences. Knowledge of and experience with ACP and end-of-life decision-making varied according to focus group, although few participants had an advance directive. Findings suggest that Chinese older adults prefer to use indirect communication strategies, such as commenting on the circumstances of others rather than directly stating their wishes, and informal contexts, such as during a family dinner rather than formal meeting, to convey their care preferences to loved ones and may employ similar tactics when communicating with clinicians. This is particularly important given the recent decision by the Centers for Medicare and Medicaid Services to provide reimbursement to physicians for engaging in advance care planning conversations.

Objectives To quantify associations between inflammatory biomarkers and hippocampal volume ( HV) and to examine effect modification according to sex, race, and age. Design Cross-sectional analyses using generalized estimating equations to account for familial clustering; standardized β-coefficients adjusted for age, sex, race, and education. Setting Community cohorts in Jackson, Mississippi and Rochester, Minnesota. Participants The Genetic Epidemiology Network of Arteriopathy study. Measurements C-reactive protein ( CRP), interleukin-6 ( IL-6), and soluble tumor necrosis factor receptors 1 ( sTNFR-1) and 2 ( sTNFR-2) from peripheral blood were measured in a sample of 773 non-Hispanic whites (61% women, aged 60.2 ± 9.8) and 514 African Americans (70% women, aged 63.9 ± 8.1) who also underwent brain magnetic resonance imaging. Biomarkers were standardized and compared according to sex, race and age with HV. Results In the full sample, higher sTNFR-1 and sTNFR-2 were associated with smaller HV. Each standard deviation ( SD) increase in sTNFR-1 was associated with 59.1 mm3 (95% confidence interval ( CI) = −101.4 to −16.7 mm3) smaller HV and each SD increase in sTNFR-2 associated with 48.8 mm3 (95% CI = −92.2 to −5.3 mm3) smaller HV. Relationships were stronger for sTNFR-2 in men ( HV = −116.6 mm3 for each SD increase, 95% CI = −201.0 to −32.1) than women ( HV = −26.0 per SD increase, 95% CI = −72.4-20.5) and sTNFR-1 in non-Hispanic whites ( HV = −84.7 mm3 per SD increase, 95% CI = −142.2 to −27.1) than African Americans ( HV = −14.1 mm3 per SD increase, 95% CI = −78.3-50.1). Associations between IL-6 or CRP and HV were not supported. Conclusion Higher levels of sTNFRs were associated cross-sectionally with smaller hippocampi. Longitudinal data are needed to determine whether these biomarkers may help to identify risk of late-life cognitive impairment. [ABSTRACT FROM AUTHOR]

Objectives To estimate the prevalence of new initiation of long-acting opioids since introduction of national efforts to increase prescriber and public awareness on safe use of transdermal fentanyl patches. Design Cross-sectional. Setting U.S. nursing homes ( NHs). Participants Medicare-enrolled long-stay NH residents (N = 22,253). Measurements Minimum Data Set 3.0 was linked with Medicare enrollment, hospital claims, and prescription drug transaction data (January-December 2011) and used to determine the prevalence of new initiation of a long-acting opioid prescribed to residents in NHs. Results Of NH residents prescribed a long-acting opioid within 30 days of NH admission (n = 12,278), 9.4% (95% confidence interval = 8.9-9.9%) lacked a prescription drug claim for a short-acting opioid in the previous 60 days. The most common initial prescriptions of long-acting opioids were fentanyl patch (51.9% of opioid-naïve NH residents), morphine sulfate (28.1%), and oxycodone (17.2%). Conclusion New initiation of long-acting opioids-especially fentanyl patches, which have been the subject of safety communications-persists in NHs. [ABSTRACT FROM AUTHOR]

Objectives To define multimorbidity 'classes' empirically based on patterns of disease co-occurrence in older Americans and to examine how class membership predicts healthcare use. Design Retrospective cohort study. Setting Nationally representative sample of Medicare beneficiaries in file years 1999-2007. Participants Individuals aged 65 and older in the Medicare Beneficiary Survey who had data available for at least 1 year after index interview (N = 14,052). Measurements Surveys (self-report) were used to assess chronic conditions, and latent class analysis ( LCA) was used to define multimorbidity classes based on the presence or absence of 13 conditions. All participants were assigned to a best-fit class. Primary outcomes were hospitalizations and emergency department visits over 1 year. Results The primary LCA identified six classes. The largest portion of participants (32.7%) was assigned to the minimal disease class, in which most persons had fewer than two of the conditions. The other five classes represented various degrees and patterns of multimorbidity. Usage rates were higher in classes with greater morbidity, but many individuals could not be assigned to a particular class with confidence (sample misclassification error estimate = 0.36). Number of conditions predicted outcomes at least as well as class membership. Conclusion Although recognition of general patterns of disease co-occurrence is useful for policy planning, the heterogeneity of persons with significant multimorbidity (≥3 conditions) defies neat classification. A simple count of conditions may be preferable for predicting usage. [ABSTRACT FROM AUTHOR]
