Discharge locations after hospitalizations involving opioid use disorder among medicare beneficiaries

BACKGROUND

Hospitalizations involving opioid use disorder (OUD) have been increasing among Medicare beneficiaries of all ages. With rising OUD-related acute care use comes the need to understand where post-acute care is provided and the capacities for OUD treatment in those settings. Our objective was to describe hospitalized Medicare beneficiaries with OUD, their post-acute care locations, and all-cause mortality and readmissions stratified by post-acute care location.

METHODS

We conducted a retrospective cohort study of acute hospitalizations using 2016-2018 Medicare Provider Analysis and Review (MedPAR) files linked to Medicare enrollment data and the Residential History File (RHF) for 100% of Medicare fee-for-service beneficiaries. The RHF which provides a person-level chronological history of health service utilization and locations of care was used to identify hospital discharge locations. We used ICD-10 codes for opioid dependence or "abuse" to identify OUD diagnoses from the MedPAR file. We conducted logistic regression to identify factors associated with discharge to an institutional setting versus home adjusting for demographics, comorbidities, and hospital stay characteristics.

RESULTS

Our analysis included 459,763 hospitalized patients with OUD. Of these, patients aged < 65 years and those dually enrolled in Medicaid comprised the majority (59.1%). OUD and opioid overdose were primary diagnoses in 14.3% and 6.2% of analyzed hospitalizations, respectively. We found that 70.3% of hospitalized patients with OUD were discharged home, 15.8% to a skilled nursing facility (SNF), 9.6% to a non-SNF institutional facility, 2.5% home with home health services, and 1.8% died in-hospital. Within 30 days of hospital discharge, rates of readmissions and mortality were 29.7% and 3.9%; respectively, with wide variation across post-acute locations. Factors associated with greater odds of discharge to institutional settings were older age, female sex, non-Hispanic White race and ethnicity, dual enrollment, longer hospital stay, more comorbidities, intensive care use, surgery, and primary diagnoses including opioid or other drug overdoses, fractures, and septicemia.

CONCLUSIONS

More than one-quarter (25.8%) of hospitalized Medicare beneficiaries with OUD received post-acute care in a setting other than home. High rates and wide variation in all-cause readmissions and mortality within 30 days post-discharge emphasize the need for improved post-acute care for people with OUD.

Association Between State Regulations Supportive of Third-party Services and Likelihood of Assisted Living Residents in the US Dying in Place

Importance

Older adults are increasingly residing in assisted living residences during their last year of life. The regulations guiding these residential care settings differ between and within the states in the US, resulting in diverse policies that may support residents who wish to die in place.

Objective

To examine the association between state regulations and the likelihood of assisted living residents dying in place. The study hypothesis was that regulations supporting third-party services, such as hospice, increase the likelihood of assisted living residents dying in place.

Design, Setting, and Participants

This retrospective cohort study combined data about assisted living residences in the US from state registries with an inventory of state regulations and administrative claims data. The study participants comprised 168 526 decedents who were Medicare beneficiaries, resided in 8315 large, assisted living residences (with ≥25 beds) across 301 hospital referral regions during the last 12 months of their lives, and died between 2017 and 2019. Descriptive analyses were performed at the state level, and 3-level multilevel models were estimated to examine the association between supportive third-party regulations and dying in place in assisted living residences. The data were analyzed from September 2021 to August 2022.

Exposures

Supportive (vs "silent," ie, not explicitly mentioned in regulatory texts) state regulations regarding hospice care, private care aides, and home health services, as applicable to licensed/registered assisted living residences across the US.

Main Outcomes and Measures

Presence in assisted living residences on the date of death.

Results

The median (IQR) age of the 168 526 decedents included in the study was 90 (84-94) years. Of these, 110 143 (65.4%) were female and 158 491 (94.0%) were non-Hispanic White. Substantial variation in the percentage of assisted living residents dying in place was evident across states, from 18.0% (New York) to 73.7% (Utah). Supportive hospice and home health regulations were associated with a higher odds of residents dying in place (adjusted odds ratio [AOR], 1.38; 95% CI, 1.24-1.54; P < .001; and AOR, 1.21; 95% CI, 1.10-1.34; P < .001, respectively). In addition, hospice regulations remained significant in fully adjusted models (AOR, 1.46; 95% CI, 1.25-1.71).

Conclusions and Relevance

The findings of this cohort study suggest that a higher percentage of assisted living residents died in place in US states with regulations supportive of third-party services. In addition, assisted living residents in licensed settings with regulations supportive of hospice regulations were especially likely to die in place.

Changes in Health and Quality of Life in US Skilled Nursing Facilities by COVID-19 Exposure Status in 2020

Importance

During the COVID-19 pandemic, the US federal government required that skilled nursing facilities (SNFs) close to visitors and eliminate communal activities. Although these policies were intended to protect residents, they may have had unintended negative effects.

Objective

To assess health outcomes among SNFs with and without known COVID-19 cases.

Design, Setting, and Participants

This retrospective observational study used US Medicare claims and Minimum Data Set 3.0 for January through November in each year beginning in 2018 and ending in 2020 including 15 477 US SNFs with 2 985 864 resident-years.

Exposures

January through November of calendar years 2018, 2019, and 2020. COVID-19 diagnoses were used to assign SNFs into 2 mutually exclusive groups with varying membership by month in 2020: active COVID-19 (≥1 COVID-19 diagnosis in the current or past month) or no-known COVID-19 (no observed diagnosis by that month).

Main Outcomes and Measures

Monthly rates of mortality, hospitalization, emergency department (ED) visits, and monthly changes in activities of daily living (ADLs), body weight, and depressive symptoms. Each SNF in 2018 and 2019 served as its own control for 2020.

Results

In 2018-2019, mean monthly mortality was 2.2%, hospitalization 3.0%, and ED visit rate 2.9% overall. In 2020, among active COVID-19 SNFs compared with their own 2018-2019 baseline, mortality increased by 1.60% (95% CI, 1.58% to 1.62%), hospitalizations decreased by 0.10% (95% CI, -0.12% to -0.09%), and ED visit rates decreased by 0.57% (95% CI, -0.59% to -0.55%). Among no-known COVID-19 SNFs, mortality decreased by 0.15% (95% CI, -0.16% to -0.13%), hospitalizations by 0.83% (95% CI, -0.85% to -0.81%), and ED visits by 0.79% (95% CI, -0.81% to -0.77%). All changes were statistically significant. In 2018-2019, across all SNFs, residents required assistance with an additional 0.89 ADLs between January and November, and lost 1.9 lb; 27.1% had worsened depressive symptoms. In 2020, residents in active COVID-19 SNFs required assistance with an additional 0.36 ADLs (95% CI, 0.34 to 0.38), lost 3.1 lb (95% CI, -3.2 to -3.0 lb) more weight, and were 4.4% (95% CI, 4.1% to 4.7%) more likely to have worsened depressive symptoms, all statistically significant changes. In 2020, residents in no-known COVID-19 SNFs had no significant change in ADLs (-0.06 [95% CI, -0.12 to 0.01]), but lost 1.8 lb (95% CI, -2.1 to -1.5 lb) more weight and were 3.2% more likely (95% CI, 2.3% to 4.1%) to have worsened depressive symptoms, both statistically significant changes.

Conclusions and Relevance

Among skilled nursing facilities in the US during the first year of the COVID-19 pandemic and prior to the availability of COVID-19 vaccination, mortality and functional decline significantly increased at facilities with active COVID-19 cases compared with the prepandemic period, while a modest statistically significant decrease in mortality was observed at facilities that had never had a known COVID-19 case. Weight loss and depressive symptoms significantly increased in skilled nursing facilities in the first year of the pandemic, regardless of COVID-19 status.

Successful Discharge of Short Stay Veterans from VA Community Living Centers

The Veterans Health Administration (VHA) long-term care rebalancing initiative encouraged VA Community Living Centers (CLCs) to shift from long-stay custodial-focused care to short-stay skilled and rehabilitative care. Using all VA CLC admissions during 2007-2010 categorized as needing short-stay rehabilitation or skilled nursing care, we assessed the patient and facility rates of successful discharge to the community (SDC) of these short-stay Veterans. We found large variation in inter- as well as intra- facility SDC rates across the rehabilitation and skilled nursing short-stay cohorts. We discuss how our results can help guide VHA policy directed at delivering high-quality short-stay CLC care for Veterans.

Effect of Deintensifying Diabetes Medications on Negative Events in Older Veteran Nursing Home Residents

OBJECTIVE

Guidelines advocate against tight glycemic control in older nursing home (NH) residents with advanced dementia (AD) or limited life expectancy (LLE). We evaluated the effect of deintensifying diabetes medications with regard to all-cause emergency department (ED) visits, hospitalizations, and death in NH residents with LLE/AD and tight glycemic control.

RESEARCH DESIGN AND METHODS

We conducted a national retrospective cohort study of 2,082 newly admitted nonhospice veteran NH residents with LLE/AD potentially overtreated for diabetes (HbA1c ≤7.5% and one or more diabetes medications) in fiscal years 2009-2015. Diabetes treatment deintensification (dose decrease or discontinuation of a noninsulin agent or stopping insulin sustained ≥7 days) was identified within 30 days after HbA1c measurement. To adjust for confounding, we used entropy weights to balance covariates between NH residents who deintensified versus continued medications. We used the Aalen-Johansen estimator to calculate the 60-day cumulative incidence and risk ratios (RRs) for ED or hospital visits and deaths.

RESULTS

Diabetes medications were deintensified for 27% of residents. In the subsequent 60 days, 28.5% of all residents were transferred to the ED or acute hospital setting for any cause and 3.9% died. After entropy weighting, deintensifying was not associated with 60-day all-cause ED visits or hospitalizations (RR 0.99 [95% CI 0.84, 1.18]) or 60-day mortality (1.52 [0.89, 2.81]).

CONCLUSIONS

Among NH residents with LLE/AD who may be inappropriately overtreated with tight glycemic control, deintensification of diabetes medications was not associated with increased risk of 60-day all-cause ED visits, hospitalization, or death.

Identification of Fall-Related Injuries in Nursing Home Residents Using Administrative Claims Data

BACKGROUND

Fall-related injuries (FRIs) are a leading cause of morbidity, mortality, and costs among nursing home (NH) residents. Carefully defining FRIs in administrative data is essential for improving injury-reduction efforts. We developed a series of novel claims-based algorithms for identifying FRIs in long-stay NH residents.

METHODS

This is a retrospective cohort of residents of NH residing there for at least 100 days who were continuously enrolled in Medicare Parts A and B in 2016. FRIs were identified using 4 claims-based case-qualifying (CQ) definitions (Inpatient [CQ1], Outpatient and Provider with Procedure [CQ2], Outpatient and Provider with Fall [CQ3], or Inpatient or Outpatient and Provider with Fall [CQ4]). Correlation was calculated using phi correlation coefficients.

RESULTS

Of 153 220 residents (mean [SD] age 81.2 [12.1], 68.0% female), we identified 10 104 with at least one FRI according to one or more CQ definition. Among 2 950 residents with hip fractures, 1 852 (62.8%) were identified by all algorithms. Algorithm CQ4 (n = 326-2 775) identified more FRIs across all injuries while CQ1 identified less (n = 21-2 320). CQ2 identified more intracranial bleeds (1 028 vs 448) than CQ1. For nonfracture categories, few FRIs were identified using CQ1 (n = 20-488). Of the 2 320 residents with hip fractures identified by CQ1, 2 145 (92.5%) had external cause of injury codes. All algorithms were strongly correlated, with phi coefficients ranging from 0.82 to 0.99.

CONCLUSIONS

Claims-based algorithms applied to outpatient and provider claims identify more nonfracture FRIs. When identifying risk factors, stakeholders should select the algorithm(s) suitable for the FRI and study purpose.

Opioid administration trends among long-stay community living centers residents with dementia

BACKGROUND

Pain assessment and management of Veterans with Alzheimer's disease and Related Dementia (ADRD) living in Community Living Centers (CLCs) is challenging. Safe and effective use of opioids in the treatment of pain is of great concern to patients and providers promulgating national policies and guidelines.

METHODS

This study examined long-stay CLC Veterans with ADRD identified in three regulatory periods (period 1: 10/2012-6/2013, n = 3347; period 2: 1/2014-11/2015, n = 4426; period 3: 1/2017-9/2018, n = 4444; Total N = 12,217).This population-based observational study used CLC Minimum Data Set (MDS) data in Fiscal Years (FYs) 2013-2018 and VA bar-code medication administration (BCMA) data. Opioid administration measures included: any opioids, long-term opioids, high-dose opioids, and co-administration with benzodiazepine. Measures were modeled using negative binomial regression with length of stay in CLC as offset adjusting for Veteran predisposing, enabling and need measures from the MDS.

RESULTS

Compared to period 1, any opioid administration was 26% lower in period 2, and 34% lower in period 3. Among Veterans who received any opioid medications over the three regulatory periods, high-dose and long-term opioid administration were more than 40% lower in periods 2 and 3 compared to period 1. Co-administration of opioid with benzodiazepine versus no opioid was 11% lower in period 2 and 34% lower in period 3 after adjusting for patient level covariates.

CONCLUSIONS

All patterns of opioid administration decreased over the four opioid regulations periods when guidelines were promulgated across the VA health system. Further research should clarify whether decreasing opioids among patients with ADRD impacted health outcomes.

Is Skilled Nursing Facility Financial Status Related to Readmission Rate Improvement?

GOAL

We examined whether higher skilled nursing facility (SNF) lagged profitability is associated with a lower 30-day all-cause all-payer risk-adjusted hospital readmission rate. Our aim was to provide insight into whether SNFs with limited financial resources are able to respond to incentives to lower their readmission rates to hospitals.

METHODS

We used data from 2012-2016 to estimate a fixed effects (FE) model with a time trend. Our data included financial data from the Centers for Medicare & Medicaid Services Healthcare Cost Report Information System SNF cost reports, facility characteristics including the all-cause all-payer risk-adjusted unplanned 30-day readmission rate from the LTCFocus (Long-Term Care Focus) project at Brown University, and county-level market variables from the Area Health Resource File. We also examined the relationship for a shorter time frame (2012-2015) after stratifying the sample by system membership or ownership.

PRINCIPAL FINDINGS

SNFs with an increase in the lagged operating margin showed a statistically significant, small decrease (<.01 percentage point) in the risk-adjusted readmission rate. The results were robust for different time periods and model specifications. Fixed effects model estimates for SNFs in the highest quartile of percentage of Medicaid patients (≥73.9%) had a lagged operating margin coefficient that is almost four times as large as the coefficient of the FE model with all SNFs.

APPLICATION TO PRACTICE

SNFs have an important role in achieving the national priority of reducing hospital readmissions. The study findings suggest that managers of SNFs should not see low profitability as an obstacle to reducing readmission rates, which is good news given the low average profitability of SNFs. Further, reductions in profitability due to penalties incurred from the recently implemented Medicare Skilled Nursing Facility Value-Based Purchasing Program may not limit SNFs' ability to lower hospital readmission rates, at least initially. However, policymakers may need to determine whether additional resources to high Medicaid SNFs can lower readmission rates for these SNFs.

Quality of Care and Outcomes Among a Diverse Group of Long-Term Care Residents With Alzheimer's Disease and Related Dementias

ObjectivesThis article assessed whether disparities among ADRD Medicare beneficiaries existed in five different long-stay quality measures. Methods: We linked individual-level data and facility-level characteristics. The main quality outcomes included whether residents: 1) were assessed/appropriately given the seasonal influenza vaccine; 2) received an antipsychotic medication; 3) experienced one/more falls with major injury; 4) were physically restrained; and 5) lost too much weight. Results: In 2016, there were 1,005,781 Medicare Advantage and fee-for-service long-term residents. About 78% were White, 13% Black, 2% Asian/Pacific Islander (Asian/PI), 6% Hispanic, and 0.4% American Indian/Alaska Native (AI/AN). Whites reported higher use of antipsychotic medications along with Hispanics and AI/AN (28%, 28%, and 27%, respectively). Similarly, Whites and AIs/ANs reported having one/more falls compared to the other groups (9% and 8%, respectively). Discussion: Efforts to understand disparities in access and quality of care among American Indians/Alaska Natives are needed, especially post-pandemic.

Patterns of oral bisphosphonate deprescribing in older nursing home residents with dementia

In a national sample of Medicare nursing home residents with dementia treated with bisphosphonates, 20% had bisphosphonates deprescribed. Residents with clinical characteristics representing decreased likelihood for long-term benefit were more likely to have bisphosphonates deprescribed. Future studies are needed to evaluate outcomes of deprescribing bisphosphonates in this population.

INTRODUCTION

To determine incidence of deprescribing bisphosphonates among nursing home (NH) residents with dementia and identify factors associated with deprescribing.

METHODS

2015-2016 Medicare claims, Part D prescriptions, Minimum Data Set (MDS) 3.0, and Nursing Home Compare for non-skilled NH residents aged 65 + with dementia and prescriptions for oral bisphosphonates overlapping the first 14 days of the stay. Our primary definition for deprescribing was a 90-day gap in medication supply; we also explored the reliability of different deprescribing definitions (30-, 90-, 180-day gaps). We estimated associations of NH, provider, and resident characteristics with deprescribing bisphosphonates using competing risks regression models.

RESULTS

Most NH residents with dementia treated with bisphosphonates (n = 5312) were ≥ 80 years old (72%), white (81%), and female (90%); about half were dependent for transfers (50%) or mobility (45%). Using a 90-day gap in supply, the 180-day cumulative incidence of deprescribing bisphosphonates was 14.8%. This increased to 32.1% using a 30-day gap and decreased to 11.7% using a 180-day gap. Factors associated with increased likelihood for bisphosphonate deprescribing were age ≥ 90 years, newly admitted (vs. prevalent stay), dependent for mobility, swallowing difficulty, > 1 hospitalization in the prior year, CCRC facility, and nurse practitioner primary provider (vs. physician). Cancer and western geographic region were associated with reduced likelihood for deprescribing.

CONCLUSION

In a national sample of NH residents with dementia, bisphosphonate deprescribing was uncommon, and associated with clinical characteristics signifying poor prognosis and decreased likelihood for long-term benefit. Future studies should evaluate clinical outcomes of deprescribing bisphosphonates in this population.

Discontinuation of beta-blockers among nursing home residents at end of life

BACKGROUND

Given limited life expectancy of nursing home (NH) residents, harms of continuing beta-blockers (BBs) may outweigh clinical benefits. Our objective was to describe beta-blocker discontinuation for NH residents during the last year of life, and identify characteristics associated with earlier discontinuation.

METHODS

This was a retrospective cohort study that included all long-stay residents in fee-for-service Medicare who died in 2016 and were prescribed oral BBs 1 year before death. Beta-blocker discontinuation was defined as a gap in medication on hand for ≥45 days per Medicare Part D claims, measured from the last date drug was on hand. Comorbidities were obtained from Chronic Condition Warehouse, and other characteristics from the Minimum Data Set. Kaplan-Meier curves were used to describe time to first discontinuation. Findings were stratified by cardiac diagnoses, perceived life expectancy of <6 months, or elevated mortality index.

RESULTS

Eighty-eight thousand two hundred and eighty-four residents were prescribed ≥1 daily BB 12 months before death. Mean age was 84.1 years and 69.2% were female. Of these, 60,573 residents (68.6%) remained on a BB in the last 45 days of life, and 57,880 residents (65.6%) had ≥1 cardiac diagnosis. Only 5239 residents (5.9%) had elevated mortality index, whereas 16,798 residents (19.0%) had perceived poor prognosis. In the last year of life, there was no difference in beta-blocker discontinuation pattern between residents with and without cardiac diagnoses. Residents with perceived poor prognosis and elevated mortality index discontinued BBs earlier. For example, mean time until discontinuation among residents with poor perceived prognosis was 245 versus 279 days in residents without such prognosis (p < 0.0001).

CONCLUSIONS

BBs are commonly prescribed to NH residents in the final year of life. Overall, discontinuation occurs earlier in residents for whom clinicians perceive limited life expectancy, suggesting that improved prognostication may offer an important opportunity to reduce polypharmacy toward end of life.

State Regulations and Hospice Utilization in Assisted Living during the Last Month of Life

OBJECTIVES

To examine the association between hospice/staffing regulations in residential care or assisted living (RC/AL) and hospice utilization among a national cohort of Medicare decedents residing in RC/AL at least 1 day during the last month of life, and to describe patterns of hospice utilization.

DESIGN

Retrospective cohort study of fee-for-service Medicare beneficiaries who died in 2018 and resided in an RC/AL community with ≥25 beds at least 1 day during the last month of life.

SETTING/PARTICIPANTS

23,285 decedents who spent time in 6274 RC/AL communities with 146 state license classifications.

METHODS

Descriptive statistics about hospice use; logistic regression models to test the association between regulations supportive of hospice care or registered nurse (RN) staffing requirements and the odds of hospice use in RC/AL in the last month of life.

RESULTS

More than half (56.4%) of the study cohort received hospice care in RC/AL at some point during the last 30 days of life, including 5.7% who received more intensive continuous home care (CHC). A larger proportion of decedents who resided in RC/ALs with supportive hospice policies received hospice (57.3% vs 52.6%), with this difference driven by more CHC hospice programs. This association remained significant after controlling for sociodemographic characteristics, comorbidities, time spent in RC/AL, and Hospital Referral Region fixed effects. Decedents in RC/ALs with explicit RN staffing requirements had significantly less CHC use (2.0% vs 6.8%).

CONCLUSIONS AND IMPLICATIONS

A large proportion of RC/AL decedents received hospice care in RC/AL regardless of differing regulations. Those in licensed settings with explicitly supportive hospice regulations were significantly more likely to receive hospice care in RC/AL during the last month of life, especially CHC level of hospice care. Regulatory change in states that do not yet explicitly allow hospice care in RC/AL may potentially increase hospice utilization in this setting, although the implications for quality of care remain unclear.

Continuity of Care and Successful Hospital Discharge of Older Veterans With Dementia

BACKGROUND

Care transitions are frequent among patients with dementia. This study aimed to estimate the impact of continuity of care (COC) on successful community discharge after hospitalization.

METHODS

National Veterans Health Administration data linked to Medicare claims in fiscal years 2014-2015. Community-dwelling older veterans with dementia with an acute hospitalization were included (n = 31,648). COC was measured by the Bice-Boxerman Continuity of Care (BBC) index (0-1). Association of COC before hospitalization on successful community discharge was examined separately among veterans discharged to the community directly and through post-acute care facilities.

RESULTS

Veterans with a 0.1 higher BBC were 4.6% (p = .06) more likely to have successful direct community discharge; but BBC had no demonstrable effect when discharge was through post-acute care facilities.

CONCLUSION

Better COC may have impact at improving successful direct community discharge, although the effect is small and the type I error rate (statistical significance) was 6%.

Rural-urban differences in diagnostic incidence and prevalence of Alzheimer's disease and related dementias

INTRODUCTION

Understanding rural-urban variation in the diagnostic incidence and prevalence of Alzheimer's disease and related dementias (ADRD) will inform policies to improve timely diagnosis and access to supportive services for older adults in rural communities.

METHODS

Using 2008 to 2015 national claims data for fee-for-service Medicare beneficiaries (roughly 170 million person-years), we computed unadjusted and adjusted diagnostic incidence and prevalence estimates for ADRD in metropolitan, micropolitan, and rural counties, and examined differences in survival rates.

RESULTS

Risk-adjusted ADRD diagnostic incidence was higher in rural versus metropolitan counties despite lower prevalence. Among beneficiaries diagnosed with ADRD in 2008, metropolitan county residents experienced longer survival compared to residents in rural and micropolitan counties.

DISCUSSION

These data suggest that older adults in rural communities may be underdiagnosed with ADRD, and/or diagnosed at later stages of dementia. Further work is needed to develop strategies to reduce this disparity.

Medicare's New Patient Driven Payment Model Resulted In Reductions In Therapy Staffing In Skilled Nursing Facilities

Medicare's Patient Driven Payment Model (PDPM) significantly altered the way skilled nursing facilities (SNFs) are paid, removing the financial incentive to maximize the volume of therapy services delivered to patients. Using federal payroll-based staffing data, we examined the effect of the PDPM on SNF therapy and nursing staff hours. After PDPM implementation, which took effect October 1, 2019, SNFs significantly reduced their therapy staff hours. Physical therapist and occupational therapist staffing levels were reduced by 5-6 percent during October-December 2019 relative to pre-PDPM levels, and physical therapy assistant and occupational therapist assistant levels were reduced by about 10 percent. These reductions were concentrated among contracted employees and were larger in SNFs with higher shares of Medicare-eligible short-stay residents. No meaningful increases in nursing staff in response to the PDPM were found. Further research is needed to determine the effect of these therapy staff reductions on SNF patient outcomes.

Rural/urban differences in discharge from rehabilitation in older adults with traumatic brain injury

BACKGROUND/OBJECTIVES

Rates of traumatic brain injury (TBI) among older adults and treatment of this population in nursing homes are increasing. The objective of this study is to examine differences in the quality of care and outcomes of older adults with TBI in rural and urban settings by (1) comparing the rates of successful community discharge; and (2) reasons for not achieving successful discharge among patients in rural and urban environments.

DESIGN

Retrospective national cohort study of skilled nursing facility (SNF) patients using Medicare inpatient claims linked with Minimum Data Set assessments. Demographic, health, and facility characteristics were compared between rural and urban settings using descriptive statistics. Logistic regression with state random effects was used to identify characteristics that predicted successful discharge.

SETTING

U.S. skilled nursing facilities (n = 11,771).

PARTICIPANTS

Medicare beneficiaries aged 66 and older discharged to a SNF following hospitalization for TBI between 2011 and 2015 (n = 61,021).

MEASUREMENTS

Successful community discharge defined as discharge from SNF within 100 days of admission and remaining in the community for ≥30 days without dying or admission to an inpatient healthcare facility.

RESULTS

Unadjusted rates of successful discharge were significantly lower for patients in rural settings compared with patients in urban settings (52.1% vs 58.5%, p < 0.01). Patients in rural settings had lower adjusted odds (odds ratio 0.84, 95% confidence interval = 0.80-0.89) of successful discharge. Reasons for not discharging successfully differed between rural and urban settings with rural patients less likely to discharge from SNF within 100 days though also less likely to be rehospitalized within 30 days of SNF discharge.

CONCLUSION

Given the low overall rate of successful community discharge and worse outcomes among rural patients, further research to explore interventions to improve SNF care and discharge planning in this population is warranted.

Functional motor improvement during inpatient rehabilitation among older adults with traumatic brain injury

BACKGROUND

Older adults comprise an increasingly large proportion of patients with traumatic brain injury (TBI) receiving care in inpatient rehabilitation facilities (IRF). However, high rates of comorbidities and evidence of declining preinjury health among older adults who sustain TBI raise questions about their ability to benefit from IRF care.

OBJECTIVES

To describe the proportion of older adults with TBI who exhibited minimal detectable change (MDC) and a minimally clinically important difference (MCID) in motor function from IRF admission to discharge; and to identify characteristics associated with clinically meaningful improvement in motor function and better discharge functional status.

DESIGN

This retrospective cohort study used Medicare administrative data probabilistically linked to the National Trauma Data Bank to estimate the proportion of patients whose motor function improved during inpatient rehabilitation and identify factors associated with meaningful improvement in motor function and motor function at discharge.

SETTING

Inpatient rehabilitation facilities in the United States.

PATIENTS

Fee-for-service Medicare beneficiaries with TBI.

MAIN OUTCOME MEASURES

Minimal Detectable Change (MDC) and Minimally Clinically Important Difference (MCID) in the Functional Independence Measure motor (FIM-M) score from admission to discharge, and FIM-M score at IRF discharge.

RESULTS

From IRF admission to discharge 84% of patients achieved the MDC threshold, and 68% of patients achieved the MCID threshold for FIM-M scores. Factors associated with a higher probability of achieving the MCID for FIM-M scores included better admission motor and cognitive function, lower comorbidity burden, and a length of stay longer than 10 days but only among individuals with lower admission motor function. Older age was associated with a lower FIM-M discharge score, but not the probability of achieving the MCID in FIM-M score.

CONCLUSION

Older adults with TBI have the potential to improve their motor function with IRF care. Baseline functional status and comorbidity burden, rather than acute injury severity, should be used to guide care planning.

Geographic variation in influenza vaccination among U.S. nursing home residents: A national study

Objectives

Estimates of influenza vaccine use are not available at the county level for U.S. nursing home (NH) residents but are critically necessary to guide the implementation of quality improvement programs aimed at increasing vaccination. Furthermore, estimates that account for differences in resident characteristics between counties are unavailable. We estimated risk‐standardized vaccination rates (RSVRs) among short‐ and long‐stay NH residents by U.S. county and identified drivers of geographic variation.

Methods

We conducted a retrospective cohort study utilizing 100% of 2013–2015 fee‐for‐service Medicare claims, Minimum Data Set assessments, Certification and Survey Provider Enhanced Reports, and Long‐Term Care: Facts on Care in the U.S. We separately evaluated short‐stay (<100 days) and long‐stay (≥100 days) residents aged 65 and older across the 2013–2014 and 2014–2015 influenza seasons. We estimated RSVRs via hierarchical logistic regression adjusting for 32 resident‐level covariates. We then used multivariable linear regression models to assess associations between county‐level NHs predictors and RSVRs.

Results

The study cohort consisted of 2,817,217 residents in 14,658 NHs across 2798 counties. Short‐stay residents had lower RSVRs than long‐stay residents (2013–2014: median [interquartile range], 69.6% [62.8–74.5] vs 84.0% [80.8–86.4]), and there was wide variation within each population (range, 11.4–89.8 vs 49.1–92.6). Several modifiable facility‐level characteristics were associated with increased RSVRs, including higher registered nurse to total nurse ratio and higher total staffing for licensed practical nurses, speech‐language pathologists, and social workers. Characteristics associated with lower RSVRs included higher percentage of residents restrained, with a pressure ulcer, and NH‐level hospitalizations per resident‐year.

Conclusions

Substantial county‐level variation in influenza vaccine use exists among short‐ and long‐stay NH residents. Quality improvement interventions to improve vaccination rates can leverage these results to target NHs located in counties with lower risk‐standardized vaccine use.

State Variation in Chronic Opioid Use in Long-Term Care Nursing Home Residents

OBJECTIVE

Policies and regulations on opioid use have evolved from being primarily state-to federally based. We examined the trends and variation in chronic opioid use among states and nursing homes.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

We used the nursing home Minimum Data Set and Medicare claims from 2014 to 2018 and included long-term care nursing home residents from each year who had at least 120 days of consecutive stay.

MEASUREMENTS

Chronic opioid use was defined as use for ≥90 days. Three-level hierarchical logistic regression models (resident, nursing home, state) were constructed to estimate intraclass correlation coefficient (ICC) at the state level and at the nursing home level. The ICC shows the proportion of variation in chronic opioid use that is attributable to states or nursing homes. All models were constructed separately for each calendar year and controlled for resident, nursing home, and state characteristics.

RESULTS

We included 3,245,714 nursing home stays from 2014 to 2018, representing 1,502,131 unique residents. The stays ranged from 676,413 in 2014 to 594,874 in 2018, with residents contributing a maximum of 1 stay per year. Chronic opioid use among nursing home residents declined from 14.1% in 2014 to 11.4% in 2018. The variation (ICC) in chronic opioid use among states declined from 2.5% in 2014 to 1.7% in 2018. In contrast, the variation (ICC) among nursing homes increased from 5.6% in 2014 to 6.5% in 2018.

CONCLUSIONS AND IMPLICATIONS

Variation in chronic opioid use declined by one-third at the state level but not at the nursing home level. National guidelines on opioid use and federal policies on opioid use may have contributed to reducing state-level variation in chronic opioid use.

Successful Community Discharge Among Older Adults With Traumatic Brain Injury in Skilled Nursing Facilities

OBJECTIVE

To identify patient, injury, and functional status characteristics associated with successful discharge to the community following a skilled nursing facility (SNF) stay among older adults hospitalized following traumatic brain injury (TBI).

SETTING

Skilled nursing facilities.

PARTICIPANTS

Medicare fee-for-service beneficiaries admitted to an SNF after hospitalization for TBI.

DESIGN

Retrospective cohort study using Medicare administrative data merged with the National Trauma Data Bank using a multilayered Bayesian record linkage approach.

MAIN OUTCOME MEASURE

Successful community discharge: discharged alive within 100 days of SNF admission and remaining in the community for 30 days or more without dying or admission to a healthcare facility.

RESULTS

Medicaid enrollment, incontinence, decreased independence with activities of daily living, and cognitive impairment were associated with lower odds of successful discharge, whereas race "other" was associated with higher odds of successful discharge. Injury factors including worse injury severity (Glasgow Coma Scale and Abbreviated Injury Scale scores) and fall-related injury mechanism were not associated with successful discharge.

CONCLUSION

Among older adults with TBI who discharge to an SNF, sociodemographic and functional status characteristics are associated with successful discharge and may be useful to clinicians for discharge planning. Acute injury severity indices may have limited utility in predicting discharge disposition once a patient is admitted to an SNF for post-acute care.

Trends in Serious Mental Illness in US Assisted Living Compared to Nursing Homes and the Community: 2007-2017

OBJECTIVE

Little is known about the prevalence of serious mental illness (SMI) in assisted living (AL) communities in the United States. Trends in the prevalence of SMI in AL communities were examined over time and in relationship to characteristics such as dual eligibility and health conditions. Within- and between-state variability of SMI in AL was also examined.

DESIGN

Samples of Medicare beneficiaries who lived in the 48 contiguous states were created: individuals who resided in the community, in a nursing home (NH), and in an AL community on December 31st of each year (2007-2017). We conducted univariate analysis to display the trends in SMI over time in AL compared with NHs and the community. To demonstrate intrastate variability, we examined the prevalence of SMI for each state. We described within-nation and within-state variability using a Lorenz curve and GINI coefficients, respectively.

RESULTS

The prevalence of SMI in AL increased by 54%, rising from 7.4% in 2007 to 11.4% in 2017. Residents with SMI were more likely to be dually eligible for Medicare and Medicaid than residents without SMI. The prevalence of SMI in AL ranged from to 3.2% in Wyoming to 33.1% in New York. Approximately 10% of AL communities had over half of the sample's AL residents with SMI.

CONCLUSION

Given the increased proportion of residents with SMI in AL, research is needed into the mental health and social care needs of this population. Analysis is needed to uncover reasons for variations among states.

Decomposing Racial and Ethnic Disparities in Nursing Home Influenza Vaccination

OBJECTIVES

Quantify how observable characteristics contribute to influenza vaccination disparities among White, Black, and Hispanic nursing home (NH) residents.

DESIGN

Retrospective cohort.

SETTING AND PARTICIPANTS

Short- and long-stay U.S. NH residents aged ≥65 years.

METHODS

We linked Minimum Data Set (MDS) and Medicare data to LTCFocUS and other facility data. We included residents with 6-month continuous enrollment in Medicare and an MDS assessment between October 1, 2013, and March 31, 2014. Residents were classified as short-stay (<100 days in NH) or long-stay (≥100 days in NH). We fit multivariable logistic regression models to assess the relationships between 27 resident and NH-level characteristics and receipt of influenza vaccination. Using nonlinear Oaxaca-Blinder decomposition, we decomposed the disparity in influenza vaccination between White versus Black and White versus Hispanic NH residents. Analyses were repeated separately for short- and long-stay residents.

RESULTS

Our study included 630,373 short-stay and 1,029,593 long-stay residents. Proportions vaccinated against influenza included 67.2% of White, 55.1% of Black, and 54.5% of Hispanic individuals among short-stay residents and 84.2%, 76.7%, and 80.8%, respectively among long-stay residents. Across 4 comparisons, the crude disparity in influenza vaccination ranged from 3.4 to 12.7 percentage points. By equalizing 27 prespecified characteristics, these disparities could be reduced 37.7% to 59.2%. Living in a predominantly White facility and proxies for NH quality were important contributors across all analyses. Characteristics unmeasured in our data (eg, NH staff attitudes and beliefs) may have also contributed significantly to the disparity.

CONCLUSIONS AND IMPLICATIONS

The racial/ethnic disparity in influenza vaccination was most dramatic among short-stay residents. Intervening on factors associated with NH quality would likely reduce these disparities; however, future qualitative research is essential to explore potential contributors that were unmeasured in our data and to understand the degree to which these factors contribute to the overall disparity in influenza vaccination.

Characterizing Emergency Department Use in Assisted Living

OBJECTIVES

Little is known about emergency department (ED) utilization among the nearly 1 million older adults residing in assisted living (AL) settings. Unlike federally regulated nursing homes, states create and enforce AL regulations with great variability, which may affect the quality of care provided. The objective of this study was to examine state variability in all-cause and injury-related ED use among residents in AL.

DESIGN

Observational retrospective cohort study.

SETTING AND PARTICIPANTS

We identified a cohort of 293,336 traditional Medicare beneficiaries residing in larger AL communities (25+ beds).

METHODS

With Medicare enrollment and claims data, we identified ED visits and classified those because of injury. We present rates of all-cause and injury-related ED use per 100 person-years in AL, by state, adjusting for age, sex, race, dual-eligibility, and chronic conditions.

RESULTS

Risk-adjusted state rates of all-cause ED visits ranged from 100.9 visits/100 AL person-years [95% confidence interval (CI) 92.8, 109.9] in New Mexico to 162.3 visits/100 AL person-years (95% CI 154.0, 174.7) in Rhode Island. The risk-adjusted rate of injury-related ED visits ranged from 18.7 visits/100 AL person-years (95% CI 17.2, 20.3) in New Mexico to 35.7 visits/100 AL person-years (95% CI 34.7, 36.8) in North Carolina.

CONCLUSIONS AND IMPLICATIONS

We observed significant variability among states in all-cause and injury-related ED use among AL residents. There is an urgent need to better understand why this variability is occurring to prevent avoidable visits to the ED.

Emergency Department Use Among Assisted Living Residents After Hurricane Irma

OBJECTIVES

Nursing home residents are especially vulnerable to adverse outcomes after a hurricane. Prior research suggests that emergency department (ED) visits increase among community-residing older adults after natural disasters. However, little is known about the impact of hurricanes on the large population of older adults residing in assisted living (AL) settings, particularly the influence of storms on the rates and causes of ED visits. We examined whether rates of ED use for injuries and other medical reasons increased after Hurricane Irma in 2017 among AL residents in Florida.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

Samples of 30,358 Medicare fee-for-service beneficiaries in 2016 and 28,922 beneficiaries in 2017 who resided in Florida AL communities.

MEASURES

The number of injury-related and other medical visits per 1,000 person-days within 30 and 90 days of September 1 in 2016 and 2017. We adjusted for age, race, sex, and chronic conditions using linear regression with AL fixed effects. We compared the top 10 primary diagnoses resulting in an ED visit between 2016 and 2017.

RESULTS

Adjusted rates of injury-related visits were 12.5% higher at 30 days but did not differ at 90 days. Other medical visits were 12% higher at 30 days in 2017 than in 2016 and 7.7% higher at 90 days. Heart failure was a leading cause of ED visits within 90 days of September 1 in 2017, unlike in 2016.

CONCLUSIONS AND IMPLICATIONS

Increased attention should be paid to AL communities in disaster preparedness and response efforts given the increased likelihood of ED visits following a hurricane.

Mandated Copayment Reductions in Medicare Advantage: Effects on Skilled Nursing Care, Hospitalizations, and Plan Exit

OBJECTIVES

To address concerns that postacute cost-sharing may deter high-need beneficiaries from participating in Medicare Advantage (MA) plans, the Centers for Medicare and Medicaid Services have capped cost-sharing for skilled nursing facility (SNF) services in MA plans since 2011. This study examines whether SNF use, inpatient use, and plan disenrollment changed following stricter regulations in 2015 that required most MA plans to eliminate or substantially reduce cost-sharing for SNF care.

DESIGN

Difference-in-differences retrospective analysis from 2013 to 2016.

SETTING

MA plans.

PARTICIPANTS

Thirty-one million MA members in 320 plans with mandatory cost-sharing reductions and 261 plans without such reductions.

MEASUREMENTS

Mean monthly number of SNF admissions, SNF days, hospitalizations, and plan disenrollees per 1000 members.

RESULTS

Mean total cost-sharing for the first 20 days of SNF services decreased from $911 to $104 in affected plans. Relative to concurrent changes in plans without mandated cost-sharing reductions, plans with mandatory cost-sharing reductions experienced no significant differences in the number of SNF days per 1000 members (adjusted between-group difference: 0.4 days per 1000 members [95% confidence interval (95% CI), -5.2 to 6.0, P=0.89], small decreases in the number of hospitalizations per 1000 members [adjusted between-group difference: 0.6 admissions per 1000 members (95% CI, -1.0 to -0.1; P=0.03)], and small decreases in the number of SNF users who disenrolled at year-end [adjusted between-group difference: -16.8 disenrollees per 1000 members (95% CI, -31.9 to -1.8; P=0.03)].

CONCLUSIONS

Mandated reductions in SNF cost-sharing may have curbed selective disenrollment from MA plans without significantly increasing use of SNF services.

Risk Factors Associated With SARS-CoV-2 Infections, Hospitalization, and Mortality Among US Nursing Home Residents

Importance

Nursing home residents account for approximately 40% of deaths from SARS-CoV-2.

Objective

To identify risk factors for SARS-CoV-2 incidence, hospitalization, and mortality among nursing home residents in the US.

Design, Setting, and Participants

This retrospective longitudinal cohort study was conducted in long-stay residents aged 65 years or older with fee-for-service Medicare residing in 15 038 US nursing homes from April 1, 2020, to September 30, 2020. Data were analyzed from November 22, 2020, to February 10, 2021.

Main Outcomes and Measures

The main outcome was risk of diagnosis with SARS-CoV-2 (per International Statistical Classification of Diseases, Tenth Revision, Clinical Modification [ICD-10-CM] codes) by September 30 and hospitalization or death within 30 days after diagnosis. Three-level (resident, facility, and county) logistic regression models and competing risk models conditioned on nursing home facility were used to determine association of patient characteristics with outcomes.

Results

Among 482 323 long-stay residents included, the mean (SD) age was 82.7 (9.2) years, with 326 861 (67.8%) women, and 383 838 residents (79.6%) identifying as White. Among 137 119 residents (28.4%) diagnosed with SARS-CoV-2 during follow up, 29 204 residents (21.3%) were hospitalized, and 26 384 residents (19.2%) died within 30 days. Nursing homes explained 37.2% of the variation in risk of infection, while county explained 23.4%. Risk of infection increased with increasing body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) (eg, BMI>45 vs BMI 18.5-25: adjusted hazard ratio [aHR], 1.19; 95% CI, 1.15-1.24) but varied little by other resident characteristics. Risk of hospitalization after SARS-CoV-2 increased with increasing BMI (eg, BMI>45 vs BMI 18.5-25: aHR, 1.40; 95% CI, 1.28-1.52); male sex (aHR, 1.32; 95% CI, 1.29-1.35); Black (aHR, 1.28; 95% CI, 1.24-1.32), Hispanic (aHR, 1.20; 95% CI, 1.15-1.26), or Asian (aHR, 1.46; 95% CI, 1.36-1.57) race/ethnicity; impaired functional status (eg, severely impaired vs not impaired: aHR, 1.15; 95% CI, 1.10-1.22); and increasing comorbidities, such as renal disease (aHR, 1.21; 95% CI, 1.18-1.24) and diabetes (aHR, 1.16; 95% CI, 1.13-1.18). Risk of mortality increased with age (eg, age >90 years vs 65-70 years: aHR, 2.55; 95% CI, 2.44-2.67), impaired cognition (eg, severely impaired vs not impaired: aHR, 1.79; 95% CI, 1.71-1.86), and functional impairment (eg, severely impaired vs not impaired: aHR, 1.94; 1.83-2.05).

Conclusions and Relevance

These findings suggest that among long-stay nursing home residents, risk of SARS-CoV-2 infection was associated with county and facility of residence, while risk of hospitalization and death after SARS-CoV-2 infection was associated with facility and individual resident characteristics. For many resident characteristics, there were substantial differences in risk of hospitalization vs mortality. This may represent resident preferences, triaging decisions, or inadequate recognition of risk of death.

Comparative effectiveness of denosumab, teriparatide, and zoledronic acid among frail older adults: a retrospective cohort study

The comparative effects of zoledronic acid, denosumab, and teriparatide for preventing hip fractures in frail older adults, especially those in nursing homes, were unknown. We found that denosumab and zoledronic acid may be as effective as teriparatide for hip fracture prevention in nursing home residents.

INTRODUCTION

Several non-oral drugs exist for osteoporosis treatment, including zoledronic acid (ZA), denosumab, and teriparatide. Little data exist on the comparative effectiveness of these drugs for hip fracture prevention in frail older adults. We examined their comparative effectiveness in one of the frailest segments of the US population-nursing home (NH) residents.

METHODS

We conducted a national retrospective cohort study of NH residents aged ≥ 65 years using 2012 to 2016 national US Minimum Data Set clinical assessment data and linked Medicare claims. New parenteral ZA, denosumab, and teriparatide use was assessed via Medicare Parts B and D; hip fracture outcomes via Part A; and 125 covariates for confounding adjustment via several datasets. We used inverse probability weighted (IPW) competing risk regression models to compare hip fracture risk between groups with teriparatide as the reference.

RESULTS

The study cohort (N = 2019) included 1046 denosumab, 578 teriparatide, and 395 ZA initiators. Mean age was 85 years, 90% were female, and 68% had at least moderate functional impairment. Seventy-two residents (3.6%) had a hip fracture and 1100 (54.5%) died over a mean follow-up of 1.5 years. Compared to teriparatide use, denosumab use was associated with a 46% lower risk of hip fracture (HR 0.54, 95% CI 0.29-1.00) and no difference was observed for ZA (HR 0.70, 95% CI 0.26-1.85).

CONCLUSIONS

Denosumab and ZA may be as effective as teriparatide for hip fracture prevention in frail older adults. Given their lower cost and easier administration, denosumab and ZA are likely preferable non-oral treatments for most frail, older adults.

Caregiver support and place of death among older adults

BACKGROUND/OBJECTIVES

As home becomes the most common place of death in the United States, information about caregiver support and place of death is critical to improve patient and caregiver experiences at end of life. We seek to examine (1) the association between family care availability and place of death; and (2) caregiving intensity associated with place of death.

DESIGN

2017 National Health and Aging Trends Study and National Study of Caregiving; nationally representative cross-sectional study of deceased older adults and last-month-of-life (LML) caregivers.

SETTING

United States; all places of deaths.

PARTICIPANTS

Three-hundred and seventy-five decedents and 267 LML caregivers.

MEASUREMENTS

Place of death (home, hospital, and nursing or hospice facility), family care availability (spouse/partner, household size, number of daughters and sons), caregiving intensity (hours of help provided at LML and a binary indicator for high care-related emotional difficulty).

RESULTS

38.9% of older adults died at home, followed by hospital (33.1%), and nursing or hospice facility (28.0%). In an adjusted multinomial logistic regression, decedents with larger household size (odds ratio [OR]: 0.441; 95% confidence interval [CI]: 0.269-0.724) and more daughters (OR: 0.743 [95% CI: 0.575-0.958]) had lower odds of dying in nursing or hospice facility relative to dying at home. For older adults who died at home, caregivers provided 209.8 h of help at LML. In contrast, when death occurred in nursing or hospice facility, caregivers provided 91.6 fewer hours of help, adjusted for decedent and caregiver characteristics. Dying in hospital was associated with higher odds of caregiver emotional difficulty relative to home deaths (OR: 4.093 [95% CI: 1.623-10.323]).

CONCLUSIONS

Household size and number of daughters are important determinants of place of death. Despite dying at home being associated with more hours of direct caregiving; caregiver emotional strain was experienced as higher for hospital deaths. Better support services for end-of-life caregivers might improve patient and caregiver experiences for home and hospital deaths.

Are Nursing Home Residents With Dementia Appropriately Treated for Fracture Prevention?

Clinicians struggle with whether to prescribe osteoporosis medications for fracture prevention for older nursing home (NH) residents with dementia, given the lack of evidence in this population. To better understand real-world clinical practice, we conducted a retrospective cohort study examining patterns of fracture prevention medication use for older NH residents with dementia and high fracture risk. Data sources included 2015-16 Medicare claims, Part D prescriptions, and Minimum Data Set (MDS) assessments. Among NH residents aged 65+ with dementia and prior fracture or high fracture risk based on the MDS FRAiL (Fracture Risk Assessment in Long-term care), we assessed medications for fracture prevention using prescription data from 1 year prior through 90 days after the first MDS assessment. Multivariable logistic regression was used to evaluate factors associated with receiving treatment. Most of the sample (n = 72,639) was >80 years (78%), female (82%), and white (88%); 63% had moderate/severe dementia and 60% had an osteoporosis diagnosis. Only 11.6% received fracture prevention medications. In adjusted analyses, treated residents were more likely to be female, Hispanic or other non-black minority, <90 years old, and newly admitted to the NH. Other associated factors included osteoporosis diagnosis, walker or wheelchair use, bone disorders (eg, Paget disease), >5 medications, steroid or proton pump inhibitor use, and regions outside of the Northeast. Resident characteristics suggestive of comorbidity burden and worsening dementia were associated with reduced likelihood of treatment. Low use of fracture prevention medications for NH residents with dementia may reflect an attempt by prescribers reconcile medication use with changing goals of care, or inappropriate underuse in patients who still have high fracture risk. Additional research is needed to help clinicians better evaluate when to use these medications in this heterogeneous and vulnerable population.

Quality of Post-Acute Care in Skilled Nursing Facilities That Disproportionately Serve Hispanics With Dementia

OBJECTIVES

As the number of Hispanics with dementia continues to increase, greater use of post-acute care in nursing home settings will be required. Little is known about the quality of skilled nursing facilities (SNFs) that disproportionately serve Hispanic patients with dementia and whether the quality of SNF care varies by the concentration of Medicare Advantage (MA) patients with dementia admitted to these SNFs.

DESIGN

Cross-sectional study using 2016 data from Medicare certified providers.

SETTING AND PARTICIPANTS

Our cohort included 177,396 beneficiaries with probable dementia from 8884 SNFs.

METHODS

We examined facility-level quality of care among facilities with high and low proportions of Hispanic beneficiaries with probable dementia enrolled in MA and fee-for-service (FFS) using data from Medicare-certified providers. Three facility-level measures were used to assess quality of care: (1) 30-day rehospitalization rate; (2) successful discharge from the facility to the community; and (3) Medicare 5-star quality ratings.

RESULTS

About 20% of residents were admitted to 1615 facilities with a resident population that was more than 15% Hispanic. Facilities with a higher share of Hispanic residents had a lower proportion of 4- or 5-star facilities by an average of 14% to 15% compared with facilities with little to no Hispanics. In addition, these facilities had a 1% higher readmission rate. There were also some differences in the quality of facilities with high (>26.5%) and low (<26.5%) proportions of MA beneficiaries. On average, SNFs with a high concentration of MA patients have lower readmission rates and higher successful discharge, but lower star ratings.

CONCLUSIONS AND IMPLICATIONS

Achieving better quality of care for people with dementia may require efforts to improve the quality of care among facilities with a high concentration of Hispanic residents.

Assessment of Rural-Urban Differences in Health Care Use and Survival Among Medicare Beneficiaries With Alzheimer Disease and Related Dementia

IMPORTANCE

There is poor understanding as to how survival and health care use varies among older adults living with Alzheimer disease and related dementia (ADRD) in rural vs urban areas of the United States.

OBJECTIVE

To describe survival and trajectories of hospital, hospice, nursing home, and home health care use among rural and urban Medicare beneficiaries with ADRD in the 6 years after diagnosis.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study linked Medicare claims data from January 1, 2009, to December 31, 2016, with nursing home and home health assessment data from all US counties. A total of 555 333 Medicare fee-for-service beneficiaries newly diagnosed with ADRD in 2010 were included. A total of 424 561 individuals (76.5%) resided in metropolitan counties, 75 001 (13.5%) in micropolitan counties, and 55 771 (10.0%) in rural counties.

EXPOSURES

Rurality of beneficiary's county of residence.

MAIN OUTCOMES AND MEASURES

Number of days survived after initial ADRD diagnosis; percent of survived days per month spent in the hospital, hospice nursing home, community with home health care services, and community without home health care services.

RESULTS

A total of 555 333 Medicare beneficiaries (mean [SD] age, 82.0 [7.5] years; 345 294 women [62.2%]; 480 286 White [86.5%]) were evaluated. Compared with metropolitan county residents, rural beneficiaries were younger (mean [SD] age, 81.6 [7.6] vs 82.1 [7.5] years), were less likely to be women (34 100 [61.1%] vs 264 688 [62.3%]), were more likely to be White (50 886 [91.2%] vs 361 205 [85.1%]) and Medicaid-eligible (14 264 [25.6%] vs 71 656 [16.9%]), and had fewer preexisting chronic conditions (mean [SD], 6.9 [2.8] vs 7.4 [2.9]). Medicare beneficiaries residing in metropolitan counties survived a mean (SD) of 1183.5 (826.0) days after diagnosis. Adjusting for individual demographic and clinical characteristics, rural and micropolitan county residents survived approximately 1.5 months less than metropolitan residents. The adjusted share of survived days spent in nursing homes was 5.7 (95% CI, 4.0-7.5) percentage points higher for rural vs metropolitan residents. The adjusted share of days in hospitals was 0.7 (95% CI, -0.9 to -0.4) percentage points lower, and the share of days in community without home health care was 4.6 (95% CI, -6.1 to -3.1) percentage points lower for rural vs metropolitan county residents. There were no statistically significant differences in home health or hospice use. Similar patterns were found for micropolitan vs metropolitan residents as for rural vs metropolitan residents, although the magnitude of the differences were smaller. Differences in time spent in community and nursing homes between rural vs metropolitan beneficiaries became more pronounced with further time from diagnosis.

CONCLUSIONS AND RELEVANCE

Study results suggest that, after diagnosis, rural Medicare beneficiaries with ADRD spend more time in nursing homes and less time in the community, receive less home health care, and have shorter survival than their urban counterparts.

Positive Beliefs and the Likelihood of Successful Community Discharge From Skilled Nursing Facilities

OBJECTIVES

To examine the association of patient and direct-care staff beliefs about patients' capability to increase independence with activities of daily living (ADL) and the probability of successful discharge to the community after a skilled nursing facility (SNF) stay.

DESIGN

Retrospective cohort study of SNF patients using 100% Medicare inpatient claims and Minimum Data Set resident assessment data. Linear probability models were used to estimate the probability of successful discharge based on patient and staff beliefs about the patient's ability to improve in function, as well as patient and staff beliefs together. Estimates were adjusted for demographics, health status, functional characteristics, and SNF fixed effects.

PARTICIPANTS

Fee-for-service Medicare beneficiaries (N=526,432) aged 66 years or older who were discharged to an SNF after hospitalization for stroke, hip fracture, or traumatic brain injury.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Successful community discharge (discharged alive within 90d of SNF admission and remaining in the community for ≥30d without dying or health care facility readmission).

RESULTS

Patients with positive beliefs about their capability to increase independence with ADLs had a higher adjusted probability of successful discharge than patients with negative beliefs (positive, 63.8%; negative, 57.8%; difference, 6.0%, 95% confidence interval [CI], 5.4-6.6). This remained true regardless of staff beliefs, but the difference in successful discharge probability between patients with positive and negative beliefs was larger when staff had positive beliefs. Conversely, the association between staff beliefs and successful discharge varied based on patient beliefs. If patients had positive beliefs, the difference in the probability of successful discharge between positive and negative staff beliefs was 2.5% (95% CI, 1.0-4.0). If patients had negative beliefs, the difference between positive and negative staff beliefs was -4.6% (95% CI, -6.0 to -3.2).

CONCLUSIONS

Patients' beliefs have a significant association with the probability of successful discharge. Understanding patients' beliefs is critical to appropriate goal-setting, discharge planning, and quality SNF care.

Cluster-randomized trial of adjuvanted vs. non-adjuvanted trivalent influenza vaccine in 823 U.S. nursing homes

BACKGROUND

Influenza leads in preventable infection-related hospitalization in nursing home (NH) residents. The adjuvanted trivalent influenza vaccine (aTIV) is more immunogenic than similarly-dosed non-adjuvanted trivalent influenza vaccine (TIV) and observational studies suggest aTIV better prevents hospitalizations in older adults. We prospectively tested this in a NH setting.

METHODS

NHs with ≥ 50 long-stay residents ≥ 65 years were randomized to offer aTIV or TIV for residents for the 2016-17 influenza season. Using intent-to-treat resident-level analysis with Cox proportional hazards regression models adjusted for clustering by facility and a priori baseline covariates (e.g., age, heart failure, and facility-level characteristics), we assessed relative aTIV:TIV effectiveness for hospitalization [i.e., all-cause, respiratory, and pneumonia and influenza, (P&I)].

RESULTS

We randomized 823 NHs, housing 50,012 eligible residents, to aTIV or TIV. Residents were similar between groups by age (mean, ~79), heart failure, lung disease, and influenza and pneumococcal vaccine uptake, except aTIV homes housed fewer Black residents (14.5 vs. 18.9%). Staff vaccine uptake was similar (~55%). P&I and all-cause resident hospitalization rates were lower (adjusted HR 0.80, 95% CI: 0.66, 0.98, p=0.03; aHR 0.94, 95% CI: 0.89, 0.99, p=0.02, respectively) for aTIV vs TIV, while the respiratory hospitalization rate was similar, in a season where vaccine effectiveness was considered poor.

CONCLUSIONS

aTIV was more effective than TIV in preventing all-cause and P&I hospitalization from NHs during an A/H3N2 predominant season when TIV was relatively ineffective.Funded by Seqirus. ClinicalTrials.gov number, NCT02882100.

Secular Trends in the Incidence of Hip Fracture Among Nursing Home Residents

A recent study suggested a decline in the incidence of hip fracture among US women between 2002 and 2012, followed by a leveling in the incidence rate from 2013 to 2015. Newly admitted nursing home residents are particularly vulnerable to hip fracture, and it is unclear whether that trend is observed in this high risk group. The purpose of our study was to describe trends in hip fracture rates and postfracture mortality among 2.6 million newly admitted US nursing home residents from 2007 to 2015, and to examine whether these trends could be explained by differences in resident characteristics. Medicare claims data were linked with the Minimum Data Set (MDS), a clinical assessment performed quarterly on all nursing home residents. In each year (2007-2015), we identified newly admitted long-stay (ie, 100 days in the same facility) nursing home residents. Hip fracture was defined using Medicare Part A diagnostic codes. Follow-up time was calculated from the index date until the first event of hospitalized hip fracture, Medicare disenrollment, death, or until 1 year. Poisson regression was used to adjust rates of hip fracture for age and sex. The number of newly admitted nursing home residents ranged from 324,508 in 2007 to 257,350 in 2015. Although mean age remained similar (83 years), residents were more functionally dependent over time. There was a small absolute decrease in the incidence rate of hip fracture between 2007 (3.32/100 person-years) and 2013 (2.82/100 person-years), with an increase again in 2015 (3.03/100 person-years). Adjusting for patient characteristics somewhat attenuated these trends. One-year mortality was high following fracture in all years (42.6% in 2007, 42.1% in 2014). In summary, we observed a recent slight rise in the incidence rates of hip fracture among nursing home residents that was at least partially explained by differences in resident characteristics over time. © 2020 American Society for Bone and Mineral Research.

Continuity of care and health care cost among community-dwelling older adult veterans living with dementia

OBJECTIVES

To estimate the causal impact of continuity of care (COC) on total, institutional, and noninstitutional cost among community-dwelling older veterans with dementia.

DATA SOURCES

Combined Veterans Health Administration (VHA) and Medicare data in Fiscal Years (FYs) 2014-2015.

STUDY DESIGN

FY 2014 COC was measured by the Bice-Boxerman Continuity of Care (BBC) index on a 0-1 scale. FY 2015 total combined VHA and Medicare cost, institutional cost of acute inpatient, emergency department [ED], long-/short-stay nursing home, and noninstitutional long-term care (LTC) cost for medical (like skilled-) and social (like unskilled-) services were assessed controlling for covariates. An instrumental variable for COC (change of residence by more than 10 miles) was used to account for unobserved health confounders.

DATA COLLECTION

Community-dwelling veterans with dementia aged 66 and older, enrolled in Traditional Medicare (N = 102 073).

PRINCIPAL FINDINGS

Mean BBC in FY 2014 was 0.32; mean total cost in FY 2015 was $35 425. A 0.1 higher BBC resulted in (a) $4045 lower total cost; (b) $1597 lower acute inpatient cost, $119 lower ED cost, $4368 lower long-stay nursing home cost; (c) $402 higher noninstitutional medical LTC and $764 higher noninstitutional social LTC cost. BBC had no impact on short-stay nursing home cost.

CONCLUSIONS

COC is an effective approach to reducing total health care cost by supporting noninstitutional care and reducing institutional care.

Comparative Effectiveness of Angiotensin II Receptor Blockers and Angiotensin-Converting Enzyme Inhibitors in Older Nursing Home Residents After Myocardial Infarction: A Retrospective Cohort Study

BACKGROUND

Evidence regarding differences in outcomes between angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) among older nursing home (NH) residents after acute myocardial infarction (AMI) is limited.

OBJECTIVES

The purpose of our study was to estimate the post-AMI effects of ARBs versus ACEIs on mortality, rehospitalization, and functional decline outcomes in this important population.

METHODS

This retrospective cohort study used national Medicare claims linked to Minimum Data Set assessments. The study population included individuals aged ≥ 65 years who resided in a US NH ≥ 30 days, were hospitalized for AMI between May 2007 and March 2010, and returned to the NH. We compared 90-day mortality, rehospitalization, and functional decline outcomes between ARB and ACEI users with inverse-probability-of-treatment-weighted binomial and multinomial logistic regression models.

RESULTS

Of the 2765 NH residents, 270 (9.8%) used ARBs and 2495 (90.2%) used ACEIs. The mean age of ARB versus ACEI users was 82.3 versus 82.7 years, respectively. No marked differences existed between ARB and ACEI users for mortality [odds ratio (OR) 1.18; 95% confidence interval (CI) 0.78-1.79], rehospitalization (OR 1.22; 95% CI 0.90-1.65), or functional decline (OR 1.23; 95% CI 0.88-1.74). In subgroup analyses, ARBs were associated with increased mortality and rehospitalization in individuals with moderate to severe cognitive impairment and with increased rehospitalization in those aged < 85 years.

CONCLUSIONS

Our findings align with prior data and suggest that clinicians can prescribe either ARBs or ACEIs post-AMI for secondary prevention in NH residents, although the subgroup findings merit further scrutiny and replication. Providers should consider factors such as patient preferences, class-specific adverse events, and costs when prescribing.

Discontinuation of Statins in Veterans Admitted to Nursing Homes near the End of Life

BACKGROUND/OBJECTIVES

Geriatric guidelines recommend against statin use in older adults with limited life expectancy (LLE) or advanced dementia (AD). This study examined resident and facility factors predicting statin discontinuation after nursing home (NH) admission in veterans with LLE/AD taking statins for secondary prevention.

DESIGN

Retrospective cohort study of Veterans Affairs (VA) bar code medication administration records, Minimum Data Set (MDS) assessments, and utilization records linked to Medicare claims.

SETTING

VA NHs, known as community living centers (CLCs).

PARTICIPANTS

Veterans aged 65 and older with coronary artery disease, stroke, or diabetes mellitus, type II, admitted in fiscal years 2009 to 2015, who met criteria for LLE/AD on their admission MDS and received statins in the week after admission (n = 13,110).

MEASUREMENTS

Residents were followed until statin discontinuation (ie, gap in statin use ≥14 days), death, or censoring due to discharge, day 91 of the stay, or end of the study period. Competing risk models assessed cumulative incidence and predictors of discontinuation, stratified by whether the resident had their end-of-life (EOL) status designated or used hospice at admission.

RESULTS

Overall cumulative incidence of statin discontinuation was 31% (95% confidence interval [CI] = 30%-32%) by day 91, and it was markedly higher in those with (52%; 95% CI = 50%-55%) vs without (25%; 95% CI = 24%-26%) EOL designation/hospice. In patients with EOL designation/hospice (n = 2,374), obesity, congestive heart failure, and admission from nonhospital settings predicted decreased likelihood of discontinuation; AD, dependency in activities of daily living, greater number of medications, and geographic region predicted increased likelihood of discontinuation. In patients without EOL designation/hospice (n = 10,736), older age and several specific markers of poor prognosis predicted greater discontinuation, whereas obesity/overweight predicted decreased discontinuation.

CONCLUSION

Most veterans with LLE/AD taking statins for secondary prevention do not discontinue statins following CLC admission. Designating residents as EOL status, hospice use, and individual clinical factors indicating poor prognosis may prompt deprescribing.

Trends In Hospitals And Skilled Nursing Facilities Sharing Medical Providers, 2008-16

Hospitals and skilled nursing facilities (SNFs) face increasing pressure to improve care coordination and reduce unnecessary readmissions. One strategy to accomplish this is to share physicians and advanced practice clinicians, so that the same providers see patients in both settings. Using 2008-16 Medicare claims, we found that as SNFs moved increasingly toward using SNF specialists, there was a steady decline in the number of facilities sharing medical providers and in the proportion of SNF primary care delivered by provider practices with both hospital and SNF clinicians (hospital-SNF practices). In SNF fixed effects analyses, we found that SNFs that increased primary care visits by hospital-SNF practices had slightly fewer readmissions, shorter lengths-of-stay, and increased successful community discharges. These findings suggest that SNFs that share medical providers with hospitals may see some benefit from that linkage, although the magnitude of the benefit may be small.

Antihypertensive Deprescribing in Older Adult Veterans at End of Life Admitted to Veteran Affairs Nursing Homes

OBJECTIVES

Geriatric palliative care approaches support deprescribing of antihypertensives in older nursing home (NH) residents with limited life expectancy and/or advanced dementia (LLE/AD) who are intensely treated for hypertension (HTN), but information on real-world deprescribing patterns in this population is limited. We examined the incidence and factors associated with antihypertensive deprescribing.

DESIGN

National, retrospective cohort study.

SETTING AND PARTICIPANTS

Older Veterans with LLE/AD and HTN admitted to VA NHs in fiscal years 2009-2015 with potential overtreatment of HTN at admission, defined as receiving at least 1 antihypertensive class of medications and mean daily systolic blood pressure (SBP) <120 mm Hg.

MEASURES

Deprescribing was defined as subsequent dose reduction or discontinuation of an antihypertensive for ≥7 days. Competing risk models assessed cumulative incidence and factors associated with deprescribing.

RESULTS

Within our sample (n = 10,574), cumulative incidence of deprescribing at 30 days was 41%. Veterans with the greatest level of overtreatment (ie, multiple antihypertensives and SBP <100 mm Hg) had an increased likelihood (hazard ratio 1.75, 95% confidence interval 1.59, 1.93) of deprescribing vs those with the lowest level of overtreatment (ie, one antihypertensive and SBP ≥100 to <120 mm Hg). Several markers of poor prognosis (ie, recent weight loss, poor appetite, dehydration, dependence for activities of daily living, pain) and later admission year were associated with increased likelihood of deprescribing, whereas cardiovascular risk factors (ie, diabetes, congestive heart failure, obesity), shortness of breath, and admission source from another NH or home/assisted living setting (vs acute hospital) were associated with decreased likelihood.

CONCLUSIONS AND IMPLICATIONS

Real-world deprescribing patterns of antihypertensives among NH residents with HTN and LLE/AD appear to reflect variation in recommendations for HTN treatment intensity and individualization of patient care in a population with potential overtreatment. Factors facilitating deprescribing included treatment intensity and markers of poor prognosis. Comparative effectiveness and safety studies are needed to guide clinical decisions around deprescribing and HTN management.

Utilization and Cost Effects of the VHA Caring for Older Adults and Caregivers at Home (COACH) Program

Since 2010, the Veterans Health Administration has initiated a home-based Caring for Older Adults and Caregivers at Home (COACH) program to provide clinical support to dementia patients and family caregivers. But its impact on health care utilization and costs is unknown. We compared 354 COACH care recipients with a propensity score weighted comparison group of 9,857 community-dwelling Veterans during fiscal years 2010-2015. In 1-year follow-up, COACH program was associated with a lower rate of long-term nursing home placement (average treatment effect on the treated [ATT] -3%; p = .01). The program increased utilization of emergency services (ATT 6%; p = .01), hospitals (ATT 10%; p < .001), and personal care services (ATT 31%; p < .001). Health care costs were also significantly increased. Improved access to services may have enabled COACH Veterans to stay at home longer. As one of Veterans Health Administration's top priorities to expand caregiver assistance programs, COACH seems to be a promising model for a nationwide implementation.

State Variability in the Prevalence and Healthcare Utilization of Assisted Living Residents with Dementia

OBJECTIVES

Almost 1 million older and disabled adults who require long-term care reside in assisted living (AL), approximately 40% of whom have a diagnosis of Alzheimer's disease and related dementias (ADRD). States vary in their regulations specific to dementia care that may influence the presence of residents with ADRD in AL and their outcomes. The objectives of this study were to describe the state variability in the prevalence of ADRD among Medicare beneficiaries residing in larger (25+ bed) ALs and their healthcare utilization.

DESIGN

Retrospective observational national study.

PARTICIPANTS

National cohort of 293,336 Medicare fee-for-service enrollees residing in larger (25+ bed) ALs in 2016 and 2017 including 88,867 (30.3%) residents with ADRD. We compared this cohort's characteristics and healthcare utilization with that of individuals with ADRD who resided in nursing homes (NHs; n = 602,521) and the community (n = 2,074,420).

METHODS

Medicare enrollment data, claims, and the NH Minimum Data Set were used to describe differences among ADRD patients in AL, NHs, and the community. We present rates of NH admission and hospitalization, by state, adjusting for age, sex, race, dual eligibility, and chronic conditions.

RESULTS

The prevalence of ADRD among AL residents varied by state, ranging from 24% to 47%. In 2017, AL residents with ADRD had higher rates of NH admission than their community-dwelling counterparts (adjusted national average = 24%, ranging from 14% to 35% among states). AL residents with ADRD had higher rates of hospitalization (38%) than populations in either NHs (29%) or the community (34%), and ranged from 29% to 45% of residents among states.

CONCLUSION

These findings have implications for states as they regulate AL and for healthcare professionals whose patients reside in AL. Future work is needed to understand specific elements of states' regulatory environments and local markets that may impact access and outcomes for this vulnerable population of residents with ADRD.

Time Trends in Opioid Use by Dementia Severity in Long-Term Care Nursing Home Residents

OBJECTIVE

Current information on opioid use in nursing home residents, particularly those with dementia, is unknown. We examined the temporal trends in opioid use by dementia severity and the association of dementia severity with opioid use in long-term care nursing home residents.

DESIGN

Repeated measures cross-sectional study.

SETTING

Long-term care nursing homes.

PARTICIPANTS

Using 20% Minimum Data Set (MDS) and Medicare claims from 2011-2017, we included long-term care residents (n = 734,739) from each year who had 120 days of consecutive stay. In a secondary analysis, we included residents who had an emergency department visit for a fracture (n = 12,927).

MEASUREMENTS

Dementia was classified as no, mild, moderate, and severe based on the first MDS assessment each year. In the 120 days of nursing home stay, opioid use was measured as any, prolonged (>90 days), and high-dose (≥90 morphine milligram equivalent dose/day). For residents with a fracture, opioid use was measured within 7 days after emergency department discharge. Association of dementia severity with opioid use was evaluated using logistic regression.

RESULTS

Overall, any opioid use declined by 8.5% (35.2% to 32.2%, P < .001), prolonged use by 5.0% (14.1% to 13.4%, P < .001), and high-dose by 21.4% (1.4% to 1.1%, P < .001) from 2011 to 2017. Opioid use declined across 4 dementia severity groups. Among residents with fracture, opioid use declined by 9% in mild, 9.5% in moderate, and 12.3% in severe dementia. The odds of receiving any, prolonged, and high-dose opioids decreased with increasing severity of dementia. For example, severe dementia reduced the odds of any [23.5% vs 47.6%; odds ratio (OR) 0.56, 95% confidence interval (CI) 0.55-0.57], prolonged (9.8% vs 20.7%; OR 0.69, 95% CI 0.67-0.71), and high-dose (1.0% vs 2.3%; OR 0.69, 95% CI 0.63-0.74) opioids.

CONCLUSIONS AND IMPLICATIONS

Use of opioids declined in nursing home residents from 2011 to 2017, and the use was lower in residents with dementia, possibly reflecting suboptimal pain management in this population.

The Changing Adoption of Culture Change Practices in U.S. Nursing Homes

BACKGROUND AND OBJECTIVES

The study aimed to: (i) describe whether culture change (CC) practice implementation related to physical environment, resident-centered care, and staff empowerment increased within the same nursing homes (NHs) over time; and (ii) identify factors associated with observed increases.

RESEARCH DESIGN AND METHODS

This was a nationally representative panel study of 1,584 U.S. NHs surveyed in 2009/2010 and 2016/2017. Survey data were merged with administrative, NH, and market-level data. Physical environment, staff empowerment, and resident-centered care domain scores were calculated at both time points. Multivariate logistic regression models examined factors associated with domain score increases.

RESULTS

Overall, 22% of NHs increased their physical environment scores over time, 32% their staff empowerment scores, and 44% their resident-centered care scores. However, 32%-68% of NHs with below median baseline scores improved their domain scores over time compared with only 11%-21% of NHs with baseline scores at or above the median. Overall, NHs in states with Medicaid pay-for-performance (with CC components), in community care retirement communities, with special care units and higher occupancy had significantly higher odds of increases in physical environment scores. Only baseline domain scores were associated with increases in staff empowerment and resident-centered care scores.

DISCUSSION AND IMPLICATIONS

This is the first nationally representative panel study to assess NH CC adoption. Many NHs increased their CC practices, though numerous others did not. While financial incentives and indicators of financial resources were associated with increase in physical environment scores, factors associated with staff empowerment and resident-centered care improvements remain unclear. Studies are needed to assess whether the observed increases in CC adoption are associated with greater quality of life and care gains for residents and whether there is a threshold effect beyond which the efficacy of additional practice implementation may be less impactful.

Association Between Secondary Prevention Medication Use and Outcomes in Frail Older Adults After Acute Myocardial Infarction

Background Secondary prevention medications are often not prescribed to frail, older adults following acute myocardial infarction, potentially because of the absence of data to support use, perceived lack of benefit, and concern over possible harms. We examined the effect of using more guideline-recommended medications after myocardial infarction on mortality, rehospitalization, and functional decline in the frailest and oldest segment of the US population-long-stay nursing home residents. Methods and Results We conducted a retrospective cohort study of nursing home residents aged ≥65 years using 2007 to 2010 national US Minimum Data Set clinical assessment data and Medicare claims. Exposure was the number of secondary prevention medications (antiplatelets, β-blockers, statins, and renin-angiotensin-aldosterone system inhibitors) initiated after myocardial infarction. Outcomes were 90-day death, rehospitalization, and functional decline. We compared outcomes for new users of 2 versus 1 and 3 or 4 versus 1 medications using the inverse probability of treatment-weighted odds ratios with 95% CI. The cohort comprised 4787 residents, with a total of 509 death, 820 functional decline, and 1226 rehospitalization events. Compared with individuals who initiated 1 medication, mortality odds ratios were 0.98 (95% CI, 0.79-1.22) and 0.74 (95% CI, 0.57-0.97) for users of 2 and 3 or 4 medications, respectively. Rehospitalization odds ratios were 1.00 (95% CI, 0.85-1.17) for 2 and 0.97 (95% CI, 0.8-1.17) for 3 or 4 medications. Functional decline odds ratios were 1.04 (95% CI, 0.85-1.28) for 2 and 1.12 (95% CI, 0.89-1.40) for 3 or 4 medications. In a stability analysis excluding antiplatelet drugs from the exposure definition, more medication use was associated with functional decline. Conclusions Use of more guideline-recommended medications after myocardial infarction was associated with decreased mortality in older, predominantly frail adults, but no difference in rehospitalization. Results for functional decline from the main and stability analyses were discordant and did not rule out an increased risk associated with more medication use.

Effects of Statins for Secondary Prevention on Functioning and Other Outcomes Among Nursing Home Residents

OBJECTIVES

Studies examining the effects of statins after acute myocardial infarction (AMI) excluded frail older adults, especially nursing home (NH) residents, and few examined functional outcomes. Older NH residents may benefit less from statins and be particularly susceptible to adverse drug events like myopathy-related functional decline. We evaluated the effects of statins on 1-year functional decline, rehospitalization, and death in NH residents.

DESIGN

We conducted a retrospective cohort study using 2007-2010 linked national data from Minimum Data Set (MDS) assessments, Medicare claims, and Online Survey Certification and Reporting System records.

SETTING AND PARTICIPANTS

We included US NH residents 65 years and older who were statin nonusers, were hospitalized for AMI between May 2007 and March 2010, and returned to the NH.

MEASURES

Outcomes were functional decline, death, and rehospitalization in the first year after post-AMI NH admission. New statin users were 1:1 propensity-score matched to nonusers to adjust for 92 characteristics. We estimated hazard ratios (HRs) and restricted mean survival time differences with 95% confidence intervals (CIs) comparing individuals who did vs did not initiate statin therapy after AMI hospitalization.

RESULTS

Propensity-score matching yielded a cohort of 5440 residents. Mean age was 83 years and 69% were female. Statin use was associated with a reduction in mortality (HR 0.80, 95% CI 0.73-0.87), corresponding to a mean of 15.9 (95% CI 9.9-22.0) days of extended life expectancy. No overall differences in rehospitalization (HR 1.06, 95% CI 0.98-1.14) or functional decline (HR 1.00, 95% CI 0.88-1.14) were observed.

CONCLUSIONS AND IMPLICATIONS

Statins may reduce 1-year mortality by 20% without affecting function among older NH residents who wish to live longer after AMI. During shared decision making with these patients or their representatives, clinicians should consider communicating that the average benefit of statins is 16 days of additional survival over 1 year.

Variability in Transitional Care Outcomes Across Hospitals Discharging Veterans to Skilled Nursing Facilities

BACKGROUND

The period after transition from hospital to skilled nursing facility (SNF) is high-risk, but variability in outcomes related to transitions across hospitals is not well-known.

OBJECTIVES

Evaluate variability in transitional care outcomes across Veterans Health Administration (VHA) and non-VHA hospitals for Veterans, and identify characteristics of high-performing and low-performing hospitals.

RESEARCH DESIGN

Retrospective observational study using the 2012-2014 Residential History File, which concatenates VHA, Medicare, and Medicaid data into longitudinal episodes of care for Veterans.

SUBJECTS

Veterans aged 65 or older who were acutely hospitalized in a VHA or non-VHA hospital and discharged to SNF; 1 transition was randomly selected per patient.

MEASURES

Adverse "transitional care" outcomes were a composite of hospital readmission, emergency department visit, or mortality within 7 days of hospital discharge.

RESULTS

Among the 365,942 Veteran transitions from hospital to SNF across 1310 hospitals, the composite outcome rate ranged from 3.3% to 23.2%. In multivariable analysis adjusting for patient characteristics, hospital discharge diagnosis and SNF category, no single hospital characteristic was significantly associated with the 7-day adverse outcomes in either VHA or non-VHA hospitals. Very few high or low-performing hospitals remained in this category across all 3 years. The increased odds of having a 7-day event due to being treated in a low versus high-performing hospital was similar to the odds carried by having an intensive care unit stay during the index admission.

CONCLUSIONS

While variability in hospital outcomes is significant, unmeasured care processes may play a larger role than currently measured hospital characteristics in explaining outcomes.

Risk for Health Events After Deprescribing Acetylcholinesterase Inhibitors in Nursing Home Residents With Severe Dementia

BACKGROUND/OBJECTIVE

Reevaluation of the appropriateness of acetylcholinesterase inhibitors (AChEIs) is recommended in older adults with severe dementia, given the lack of strong evidence to support their continued effectiveness and risk for medication-induced adverse events. We sought to evaluate the impact of deprescribing AChEIs on risk of all-cause events (hospitalizations, emergency department visits, and mortality) and serious falls or fractures in older nursing home (NH) residents with severe dementia.

DESIGN

Analysis of 2015 to 2016 data from Medicare claims, Part D prescriptions, Minimum Data Set (MDS) version 3.0, Area Health Resource File, and Nursing Home Compare. Marginal structural models with inverse probability of treatment weights were used to evaluate the association of deprescribing AChEIs and all-cause negative events as well as serious falls or fractures.

SETTING

US Medicare-certified NHs.

PARTICIPANTS

Nonskilled NH residents, aged 65 years and older, with severe dementia receiving AChEIs within the first 14 days of an MDS assessment in 2016 (n = 37 106).

RESULTS

The sample was primarily white (78.7%), female (75.5%), and aged 80 years or older (77.4%). Deprescribing AChEIs was associated with an increased likelihood of all-cause negative events in unadjusted models (odds ratio [OR] = 1.17; 95% confidence interval [CI] = 1.11-1.23; P < .01), but not in fully adjusted models (adjusted OR [aOR] = 1.00; 95% CI = 0.94-1.06; P = .94). By contrast, deprescribing was associated with a reduced likelihood of serious falls or fractures in unadjusted models (OR = 0.59; 95% CI = 0.52-0.66; P < .001) and remained significant in adjusted models (aOR = 0.64; 95% CI = 0.56-0.73; P < .001).

CONCLUSION

Deprescribing AChEIs was not associated with a significant increase in the likelihood for all-cause negative events and was associated with a reduced likelihood of falls and fractures in older NH residents with dementia. Our findings suggest that deprescribing AChEIs is a reasonable approach to reduce the risk of serious falls or fractures without increasing the risk for all-cause events.

State Variability in Assisted Living Residents' End-of-Life Care Trajectories

OBJECTIVE

A growing and increasingly vulnerable population resides in assisted living. States are responsible for regulating assisted living and vary in their requirements. Little is known about how this variability translates to differences in the dying experiences of assisted living residents. The objective of this study is to describe assisted living residents' end-of-life care trajectories and how they vary by state.

DESIGN

Observational retrospective cohort study.

SETTING AND PARTICIPANTS

Using Medicare data and a methodology developed to identify beneficiaries residing in larger assisted living communities (25+ beds), we identified a cohort of 40,359 assisted living residents in the continental United States enrolled in traditional Medicare and who died in 2016.

METHODS

We used Medicare data and the Residential History File to examine assisted living residents' locations of care and services received in the last 30 days of life.

RESULTS

Nationally, 57% of our cohort died outside of an institutional setting, that is, hospital or nursing home (n = 23,165), 18,396 of whom received hospice at the time of death. Rates of hospitalization and transition to a nursing home increased during the last 30 days of life. We observed significant interstate variability in the adjusted number of days spent in assisted living in the month before death [from 13.6 days (95% confidence interval [CI] 11.8, 15.4) in North Dakota to 24.0 days (95% CI 22.7, 25.2) in Utah] and wider variation in the adjusted number of days receiving hospice in the last month of life, ranging from 2.1 days (95% CI 1.0, 3.2) in North Dakota to 13.8 days (95% CI 12.1, 15.5) in Utah.

CONCLUSIONS AND IMPLICATIONS

Findings suggest that assisted living residents' dying trajectories vary significantly by state. To ensure optimal end-of-life outcomes for assisted living residents, state policy makers should consider how their regulations influence end-of-life care in assisted living, and future research should examine factors (eg, state regulations, market characteristics, provider characteristics) that may enable assisted living residents to die in place and contribute to differential access to hospice services.

Changes in Long-Term Care Markets: Assisted Living Supply and the Prevalence of Low-Care Residents in Nursing Homes

OBJECTIVES

To assess the effect of changes in assisted living (AL) capacity within a market on prevalence of residents with low care needs in nursing homes.

DESIGN

Retrospective, longitudinal analysis of nursing home markets.

SETTING AND PARTICIPANTS

Twelve thousand two hundred fifity-one nursing homes in operation during 2007 and 2014.

MEASUREMENTS

We analyzed the percentage of residents in a nursing home who qualified as low-care. For each nursing home, we constructed a market consisting of AL communities, Medicare beneficiaries, and competing nursing homes within a 15-mile radius. We estimated the effect of change in AL beds on prevalence of low-care residents using multivariate linear models with year and nursing home fixed effects.

RESULTS

The supply of AL beds increased by an average 258 beds per nursing home market (standard deviation = 591) during the study period. The prevalence of low-care residents decreased from an average of 13.0% (median 10.5%) to 12.2% (median 9.5%). In adjusted models, a 100-bed increase in AL supply was associated with a decrease in low-care residents of 0.041 percentage points (P = .026), controlling for changes in market and nursing home characteristics, county demographics, and year and nursing home fixed effects. In markets with a high percentage of its Medicare beneficiaries (≥14%) dual eligible for Medicaid, the effect of AL is stronger, with a 0.066-percentage point decrease per 100 AL beds (P = .026) vs a 0.016-percentage point decrease in low-duals markets (P = .48).

CONCLUSIONS AND IMPLICATIONS

Our analysis suggests that some of the growth in AL capacity serves as a substitute for nursing homes for patients with low care needs. Furthermore, the effects are concentrated in markets with an above-average proportion of beneficiaries with dual Medicaid eligibility.
