Disparities in COVID-19-Related Mortality Among Older Adults With Alzheimer's Disease and Related Dementias: Variations Over Time.

Older adults with Alzheimer's disease and related dementias (ADRD) had a high risk of COVID-19-related mortality. Racial and ethnic minorities were disproportionally impacted by the pandemic. The variations in disparities, including racial and ethnic disparities and disparities across communities, in COVID-19-related mortality across the different stages of the COVID-19 pandemic among the ADRD population are unknown. This observational study estimated linear probability models for community-dwelling older adults with ADRD who were diagnosed with COVID-19 in 2020 and 2021 using multiple national data (e.g., Medicare data), accounting for individual and community characteristics. Disparities in 30-day mortality were compared between 2020 and 2021. The socioeconomic disparity in COVID-19-related mortality across communities became insignificant during the later stage of the pandemic, ethnic differences in COVID-19-related mortality decreased but persisted, and racial disparity remained largely unchanged. The study provides insights into interventions to mitigate lingering disparities in health outcomes among the vulnerable population.

Telemedicine Utilization Among Residents With Alzheimer Disease and Related Dementia: Association With Nursing Home Characteristics.

OBJECTIVE: To examine telemedicine use among nursing home (NH) residents with Alzheimer disease and related dementias (ADRD) and the associations with NH characteristics. DESIGN: Observational study. SETTING AND PARTICIPANTS: 2020-2021 Minimum Data Set 3.0, Medicare datasets, and Nursing Home Compare data were linked. A total of 10,810 NHs were identified. METHODS: The outcome variable was the percentage of residents with ADRD who used telemedicine in an NH in a quarter. The main independent variables were NH racial and ethnic compositions (ie, percentages of Black and Hispanic residents) and NH rurality. A set of linear models with NH random effects were estimated. The analysis was stratified by COVID-19 pandemic stages, including the beginning of the pandemic [second quarter of 2020 (2020 Q2)], before and after the widespread of the COVID-19 vaccine (ie, 2020 Q3-2021 Q1 and 2021 Q2-2021 Q4). RESULTS: The proportion of residents with ADRD in NHs who had telemedicine use declined from 35.0% in 2020 Q2 to 9.3% in 2021 Q4. After adjusting for other NH characteristics, NHs with a high proportion of Hispanic residents were 2.7 percentage points more likely to use telemedicine for residents with ADRD than those with a low proportion during 2021 Q2-2021 Q4 (P < .001), whereas NHs with a high proportion of Black residents were 1.5 percentage points less likely to use telemedicine than those with a low proportion (P < .01). Additionally, compared with metropolitan NHs, rural NHs were 6.4 percentage points less likely to use telemedicine in 2020 Q2 (P < .001), but 5.9 percentage points more likely to use telemedicine during 2021 Q2-2021 Q4 (P < .001). We also detected the relationship between telemedicine use and other NH characteristics, such as NH quality, staffing level, and Medicaid-pay days. CONCLUSIONS AND IMPLICATIONS: The proportion of residents with ADRD in NHs who had telemedicine use decreased during the pandemic. Telemedicine could improve health care access for NHs with a high proportion of Hispanic residents and NHs in remote areas. Future studies should investigate how telemedicine use affects the health outcomes of NH residents with ADRD.

Home Health Quality among Hospitalized Older Adults with Alzheimer's Disease and Related Dementia: Association with Race/Ethnicity and Dual Eligibility before and during the COVID Pandemic.

OBJECTIVES: During the COVID-19 pandemic, home health agencies (HHAs) discharges following acute hospitalizations increased. This study examined whether racial and ethnic minoritized and socioeconomically disadvantaged patients (ie, Medicare-Medicaid dual-eligible) were differentially discharged to below-average quality HHAs before and during the COVID-19 pandemic. We focused on post-acute patients with Alzheimer's disease and related dementias (ADRD), who are generally frail and have high care needs. DESIGN: Cohort study. SETTING AND PARTICIPANTS: We linked 2019 to 2021 Medicare data with Area Deprivation Index (ADI), Home Health Compare, and COVID-19 infection data. We included Medicare beneficiaries with ADRD who were hospitalized for non-COVID-19 conditions and discharged to HHAs between January 2019 and November 2021. The final analytical sample included 426,766 qualified hospitalization events. METHODS: The outcome variable was whether a patient received care from a below-average quality HHA, defined by an average Quality of Patient Care Star Rating lower than 3.0. Key independent variables included individual race, ethnicity, and Medicare-Medicaid dual status. Linear probability models with county fixed effects were estimated, sequentially adjusting for the individual- and community-level covariates. Sensitivity analysis using various definitions of below-average quality HHAs was conducted. RESULTS: Before the pandemic, Black and Hispanic individuals had significantly higher probabilities of discharge to below-average quality HHAs compared with white individuals (3.4 and 3.9 percentage points, respectively). Dual-eligible individuals were also 2.5 percentage points more likely to be discharged to below-average quality HHAs. During the pandemic, disparities in being discharged to below-average quality HHAs persisted among racial and ethnic minoritized patients and increased among duals. Findings were consistent with and without adjusting for individual covariates and across different definitions of below-average quality HHA. CONCLUSIONS AND IMPLICATIONS: Persistent disparities were observed in being discharged to below-average quality HHAs by race, ethnicity, and dual status. Further research is needed to identify factors contributing to these ongoing inequalities.

Mental Health Treatment Among Nursing Home Residents With Alzheimer's Disease and Related Dementias.

OBJECTIVES: To examine the prevalence of mental health treatment among nursing home (NH) long-stay residents with Alzheimer's disease and related dementias (ADRD) and explore factors associated with utilization. DESIGN: Retrospective cohort study. Minimum Data Set data (April 2017-September 2018), Medicare Master Beneficiary Summary File, Part B Carrier file and Part D prescription file were used to identify mental illness and ADRD diagnoses, patient characteristics, and mental health treatment. SETTING AND PARTICIPANTS: All US Medicare- or Medicaid-certified NHs. Fee-for-service Medicare beneficiaries aged 65 and older who had a quarterly or annual Minimum Data Set assessment with ADRD and were enrolled in Medicare Parts B and D. Two cohorts: residents with both ADRD and psychiatric disorders; residents with ADRD only. METHODS: Primary outcomes: receipt of (1) any mental health treatment (medication or psychotherapy); (2) any psychotherapy in a calendar quarter. SECONDARY OUTCOMES: antipsychotics, antidepressants, hypnotics, antiepileptics, short-session ( ≤ 30 minutes), long-session ( ≥ 45 minutes), and family/group psychotherapy. Covariates included predisposing, enabling characteristics, and needs factors. Generalized Estimating Equation models of quarterly data, nested within patients, were estimated for each outcome among each cohort. RESULTS: Analyses included 1,913,945 resident-quarter observations from 503,077 unique NH long-stay residents. Overall, 68.5% of NH long-stay residents with ADRD have psychiatric disorders; of these, 85% received mental health treatment. African American or Hispanic residents were less likely to use antidepressants. African American residents or residents living in rural locations were less likely to receive long-session psychotherapy. Hispanic residents were more likely to receive long-session psychotherapy. Residents in minority groups were more likely to receive group/family psychotherapy. CONCLUSIONS AND IMPLICATIONS: Most of NH long-stay residents with ADRD had psychiatric disorders and most of them received treatment. Antidepressants or long-session psychotherapy were less likely to be provided to African American residents. Factors that determine the efficacy of mental health treatment and reasons for the racial disparities require further exploration.

Racial and ethnic differences in telemedicine use among community-dwelling older adults with dementia.

BACKGROUND: Routine ambulatory care is essential for older adults with Alzheimer's disease and related dementias (ADRD) to manage their health conditions. The federal government expanded telemedicine coverage to mitigate the impact of the COVID-19 pandemic on ambulatory services, which may provide an opportunity to improve access to care. This study aims to examine differences in telemedicine use for ambulatory services by race, ethnicity, and community-level socioeconomic status among community-dwelling older adults with ADRD. METHODS: This retrospective cohort study used Medicare claims data between April 01, 2020 and December 31, 2021. We included community-dwelling Medicare fee-for-service beneficiaries aged 65 years and older with ADRD. The outcome variable is individual's use (yes/no) of telemedicine evaluation and management (tele-EM) visits in each quarter. The key independent variables are race, ethnicity, and community-level socioeconomic status. RESULTS: The analytical sample size of the study was 2,068,937, including 9.9% Black, 82.7% White, and 7.4% Hispanic individuals. In general, we observed a decreasing trend of tele-EM use, and the average rate of quarterly tele-EM use was 23.0%. Tele-EM utilization varied by individual race, ethnicity, and community-level socioeconomic status. On average, White and Black individuals in deprived communities were 3.5 and 2.4 percentage-points less likely to use tele-EM compared with their counterparts in less-deprived communities (p < 0.001). However, Hispanic individuals in deprived communities were 2.4 percentage-points more likely to utilize tele-EM compared with those in less-deprived communities (p < 0.001). Additionally, we observed various racial and ethnic differences in telemedicine use in deprived communities versus less-deprived communities. CONCLUSIONS: We observed various racial and ethnic differences in telemedicine use, both within and between communities by socioeconomic status. Telemedicine is a viable healthcare delivery option that may influence healthcare access for racial and ethnic minorities and for individuals in socioeconomically deprived communities. Further policies or interventions may be needed to ensure all individuals have equal access to newly available care delivery models.

Telemedicine and Disparities in Mental Health Service Use Among Community-Dwelling Older Adults With Alzheimer Disease and Related Dementias.

OBJECTIVE: To examine disparities in mental health (MH) service utilization, via in-person and telemedicine (ie, tele-MH), by individuals' race, ethnicity, and community socioeconomic status, among community-dwelling older adults with Alzheimer disease and related dementias (ADRD) before and after the expansion of the Centers for Medicare and Medicaid Services' (CMS's) telemedicine policy. DESIGN: Observational study. SETTING AND PARTICIPANTS: A total of 3,003,571 community-dwelling Medicare beneficiaries with ADRD between 2019 and 2021 were included in the study. METHODS: Multiple national data were linked. The unit of analysis was individual-quarter. Three outcomes were defined: any MH visits (in-person or tele-MH), in-person MH visits, and tele-MH visits per quarter. Key independent variables included individual race and ethnicity, the socioeconomic status of the community, and an indicator for the implementation of the telemedicine policy. Regression analyses with individual random effects were used. RESULTS: In general, Black and Hispanic older adults with ADRD and those in socioeconomically deprived communities were less likely to have MH visits than white adults and those from less-deprived communities. In-person and tele-MH visits varied throughout the pandemic and across subpopulations. For instance, at the beginning of the pandemic, white, Black, and Hispanic older adults experienced 5.05, 3.03, and 2.87 percentage point reductions in in-person MH visits, and 3.53, 1.26, and 0.32 percentage point increases in tele-MH visits (with P < .01 for racial/ethnic differences), respectively. During the pandemic, the increasing trend in in-person MH visits and the decreasing trend in tele-MH visits varied across different subgroups. Overall, racial and ethnic differences in any MH visits were reduced, but the gap in any MH visits between deprived and less-deprived communities doubled during the pandemic (P < .01). CONCLUSIONS AND IMPLICATIONS: Telemedicine may have provided an opportunity to improve access to MH services among underserved populations. However, although some disparities in MH care were reduced, others widened, underscoring the importance of equitable health care access strategies to address the unique needs of different populations.

Serious Mental Illness in Assisted Living Communities: Association with Nursing Home Placement.

OBJECTIVES: Assess prevalence of serious mental illness (SMI) alone, and co-occurring with Alzheimer disease and related dementias (ADRD), among Medicare beneficiaries in assisted living (AL). Examine the association between permanent nursing home (NH) placement and SMI, among residents with and without ADRD. DESIGN: 2018-2019 retrospective cohort of Medicare beneficiaries in AL. Residents were followed for up to 2 years to track their NH placement. We used data from the Medicare Enrollment Database, the Medicare Beneficiary Summary File, Minimum Data Set, and a national directory of state-licensed AL communities. AL residents were identified using a validated, previously reported 9-digit zip code methodology. SETTING AND PARTICIPANTS: A cross-sectional study sample included 289,350 Medicare beneficiaries in 17,265 AL communities across 50 states and in the District of Columbia. METHODS: The outcome was permanent NH placement: a continuous stay for more than 90 days. Key independent variable was presence of SMI-schizophrenia, bipolar disorder, and major depression. Other covariates included sociodemographic factors and presence of other chronic conditions, including ADRD. A linear probability model with robust SEs, and AL-level random effects, was used to test the association between SMI diagnoses, ADRD, and their interactions on NH placement. RESULTS: More than half (55.65%) of AL residents had a diagnosis of SMI, among them 93.2% had major depression, 28.5% schizophrenia, and 22.2% bipolar disorder. Individuals with schizophrenia and bipolar disorder had a significantly lower probability of NH placement, a 32% and a 15% decrease relative to the cohort mean, respectively. Placement risk was significantly greater for residents with ADRD compared to those without, increasing for those who also had schizophrenia or bipolar disorder, 12.9% and 1.5% relative to the sample mean, respectively. CONCLUSION AND IMPLICATIONS: Presence of schizophrenia and bipolar disorder, in conjunction with ADRD, significantly increases the risk of long-term NH placement, suggesting that ALs may not be well prepared to care for these residents.

Assisted living residents with dementia: Disparities in mental health services pre and during COVID-19.

BACKGROUND: Little is known about mental health among Medicare beneficiaries with Alzheimer's disease or related dementias (ADRD) who reside in assisted living (AL) communities. The COVID-19 pandemic may have curtailed ambulatory care access for these residents, but telehealth may have expanded it. We examined in-person and telehealth use of ambulatory mental health visits among AL residents with ADRD, pre and during the COVID pandemic, focusing on race/ethnicity and Medicare/Medicaid dual status. METHODS: A CY2018 cohort of AL residents with ADRD was identified. Outcome was any quarterly in-person or telemedicine mental health visit based on national CY2019-2020 Medicare claims. Key independent variables were individual race/ethnicity and dual status and the AL-level proportion of dual residents. We estimated a linear probability model with random effects and robust standard errors. Quarterly indicators captured service use before and after the onset of the pandemic. RESULTS: The study included 102,758 fee-for-service Medicare beneficiaries with ADRD in 13,400 ALs. One in five residents had any mental health visits prior to the COVID-19 pandemic. Black residents, and those with dual Medicare/Medicaid eligibility, were significantly less likely to use mental health services prior to and during the pandemic. There were no significant differences in visits via telemedicine by race/ethnicity or individual dual status. Residents in AL communities with a higher proportion of duals had a lower likelihood of visits before and during the pandemic. CONCLUSIONS/IMPLICATIONS: Mental health service use among AL residents with ADRD was low and declining prior to the pandemic. Telehealth allowed for mental health visits to continue during the pandemic, albeit at a lower level. Residents in ALs with a higher proportion of duals were less likely to have in-person or telehealth visits. The results suggest that some ALs may find it difficult to assure mental health service provision to this vulnerable population.

Outcomes After Community Discharge From Skilled Nursing Facilities: The Role of Medicaid Home and Community-Based Services.

This study investigated the association between Medicaid Home and Community-Based Services (HCBS) generosity and post-discharge outcomes among dual-eligible beneficiaries discharged from skilled nursing facilities (SNFs). We linked multiple national datasets for duals discharged from SNFs between 2010 and 2013. Accounting for SNF fixed effects, we estimated the effect of HCBS generosity, measured by its breadth and intensity, on the likelihood of remaining in the community, risks of death, nursing home (NH) admission, and hospitalizations within 30 and 180 days after SNF discharge. We found that higher HCBS generosity was associated with an increased likelihood of remaining in the community. HCBS breadth and intensity were both significantly associated with reduced risks of NH admission, while higher HCBS intensity was related to a reduced risk of acute hospitalizations within 30 days after discharge. Our findings suggest that more generous HCBS programs may facilitate smoother transitions and sustainable community living following SNF discharge.
