The extended impact of the COVID-19 pandemic on long-term care residents in Medicare with frailty or dual Medicaid enrollment.

BACKGROUND: Although many healthcare settings have since returned to pre-pandemic levels of operation, long-term care (LTC) facilities have experienced extended and significant changes to operations, including unprecedented levels of short staffing and facility closures, that may have a detrimental effect on resident outcomes. This study assessed the pandemic's extended effect on outcomes for LTC residents, comparing outcomes 1 and 2 years after the start of the pandemic to pre-pandemic times, with special focus on residents with frailty and dually enrolled in Medicare and Medicaid. METHODS: Using Medicare claims data from January 1, 2018, through December 31, 2022, we ran over-dispersed Poisson models to compare the monthly adjusted rates of emergency department use, hospitalization, and mortality among LTC residents, comparing residents with and without frailty and dually enrolled and non-dually enrolled residents. RESULTS: Two years after the start of the pandemic, adjusted emergency department (ED) and hospitalization rates were lower and adjusted mortality rates were higher compared with pre-pandemic years for all examined subgroups. For example, compared with 2018-2019, 2022 ED visit rates for dually enrolled residents were 0.89 times lower, hospitalization rates were 0.87 times lower, and mortality rates were 1.17 higher; 2022 ED visit rates for frail residents were 0.85 times lower, hospitalization rates were 0.83 times lower, and mortality rates were 1.21 higher. CONCLUSIONS: In 2022, emergency department and hospital utilization rates among long-term residents were lower than pre-pandemic levels and mortality rates were higher than pre-pandemic levels. These findings suggest that the pandemic has had an extended impact on outcomes for LTC residents.

Hospital-Skilled Nursing Facility Integration and Participation in a Bundled Payment Initiative.

Importance: Reduced institutional postacute care has been associated with savings in alternative payment models. However, organizations may avoid voluntary participation if participation could threaten their own revenues. Objective: To characterize the association between hospital-skilled nursing facility (SNF) integration and participation in Medicare's Bundled Payments for Care Improvement Advanced (BPCI-A) program. Design, Setting, and Participants: This is a cross-sectional analysis of hospital participation in BPCI-A beginning with its launch in 2018. Each SNF-integrated hospital was matched with 2 nonintegrated hospitals for each of 4 episode-specific analyses. Fifteen hospital-level variables were used for matching: beds, case mix index, days, area SNF beds, metropolitan location, ownership, region, system membership, and teaching status. Hospitals were also matched on episode-specific volume, target price, and the interaction of target price and case mix. Episode-specific logistic models were estimated regressing hospital participation on integration and the previously listed variables. The marginal effect of integration on participation was then calculated. Analysis took place from August 2022 to May 2024. Exposure: Hospital-SNF integration, as defined by common ownership and referral patterns and identified using cost reports, Medicare claims, and Provider Enrollment, Chain, and Ownership System records. Additional sources included records of target prices and participation, the Area Health Resources File, and the Compendium of US Health Systems. Main Outcomes and Measures: Participation in BPCI-A. Results: In total, 1524 hospitals met criteria for inclusion in the hip and femur (HFP) analysis, 1825 were included in the major joint replacement of the lower extremity (MJRLE) analysis, 2018 were included in the sepsis analysis, and 1564, were included in the stroke-specific analysis. Across episodes, 191 HFP-eligible hospitals (12.5% of HFP-eligible hospitals), 302 MJRLE-eligible hospitals (16.5%), 327 sepsis-eligible hospitals (16.2%), and 185 sepsis-eligible hospitals (11.8%) were SNF integrated. In total, 79 hospitals (5.2%) participated in the HFP episode, 128 (7.0%) participated in the MJRLE episode, 204 (10.1%) participated in the sepsis episode, and 141 (9.0%) participated in the stroke episode. Integration was associated with a 4.7-percentage point decrease (95% CI, 2.4 to 6.9 percentage points) in participation in the MJRLE episode. There was no association between integration and participation for HFP (0.5-percentage point increase in participation moving from nonintegrated to integrated; 95% CI, -2.9 to 3.8 percentage points), sepsis (1.0-percentage point increase; 95% CI, -2.2 to 4.2 percentage points), and stroke (0.3-percentage point decrease; 95% CI, -3.1 to 3.8 percentage points). Conclusions and Relevance: In this cross-sectional study, there was an uneven association between hospital-SNF integration and participation in Medicare's BPCI-A program. Other factors may be more consistent determinants of selection into voluntary payment reform.

Four Years And More Than 200,000 Deaths Later: Lessons Learned From The COVID-19 Pandemic In US Nursing Homes.

Nursing home residents and staff were disproportionately affected by the COVID-19 pandemic, drawing attention to long-standing challenges of poor infection control, understaffing, and substandard quality of care in many facilities. Evolving practices and policies during the pandemic often focused on these challenges, with little effect. Despite the emergence of best practices to mitigate transmission of the virus, even the highest-quality facilities experienced outbreaks, indicating a larger systemic problem, rather than a quality problem at the facility level. Here we present a narrative review and discussion of the evolution of policies and practices and their effectiveness, drawing on evidence from the United States that was published during 2020-23. The lessons learned from this experience point to the need for more fundamental and nuanced changes to avoid similar outcomes from a future pandemic: greater integration of long-term care into public health planning, and ultimately a shift in the physical structure of nursing homes. More incremental measures such as vaccination mandates, higher staffing, and balancing infection control with resident quality of life will avoid some adverse outcomes, but without more systemic change, nursing home residents and staff will remain at substantial risk for repetition of the poor outcomes from the COVID-19 pandemic.

Rethinking Infection Control: Nursing Home Administrator Experiences during the COVID-19 Pandemic.

OBJECTIVE: To examine nursing home administrator perspectives of infection control practices in nursing homes at the height of the COVID-19 pandemic and characterize lessons learned. DESIGN: Descriptive qualitative study. SETTING AND PARTICIPANTS: Administrators from 40 nursing homes across 8 diverse health care markets in the United States. METHODS: Semistructured interviews were conducted via telephone or Zoom with nursing home administrators. Interviews were repeated at 3-month intervals, for a total of 4 interviews per participant between July 2020 and December 2021 (n = 156). Qualitative analysis of interview transcripts used modified grounded theory and thematic analysis to identify overarching themes. RESULTS: Three major themes emerged reflecting administrator experiences managing infection control practices and nursing home operations at the height of the COVID-19 pandemic. First, administrators reported that the more stringent infection control protocols implemented to manage and mitigate COVID-19 at their facilities increased awareness and understanding of the importance of infection control; second, administrators reported incorporating higher standards of infection control practices into facility-level policies, emergency preparedness plans, and staff training; and third, administrators said they and their executive leadership were reevaluating and upgrading their facilities' physical structures and operational processes for better infection control infrastructure in preparation for future pandemics or other public health crises. CONCLUSIONS AND IMPLICATIONS: Insights from this study's findings suggest important next steps for restructuring and improving nursing home infection control protocols and practices in preparation for future pandemics and public health emergencies. Nursing homes need comprehensive, standardized infection control training and upgrading of physical structures to improve ventilation and facilitate isolation practices when needed. Furthermore, nursing home emergency preparedness plans need better integration with local, state, and federal agencies to ensure effective communication, proper resource tracking and allocation, and coordinated, rapid response during future public health crises.

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

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

Mental health in nursing homes: The role of immigration in the long-term care workforce.

One-fourth of nursing home residents are diagnosed with anxiety disorders and approximately half live with depression. Nursing homes have long struggled with staffing shortages, and the lack of care has further heightened the risk of poor mental health. A key solution to both problems could be immigration. Prior studies have documented how immigrant labor could strengthen the long-term care workforce. We add to this picture by exploring the impact of immigrant inflows on the mental health outcomes of nursing home residents. Using a nationally representative dataset and a shift-share instrumental variable approach, we find empirical evidence that immigration reduces diagnoses of depression and anxiety, the use of antidepressant and antianxiety drugs, and self-assessed symptoms of depression. The results are robust to several sensitivity tests. We further find that the effect is more substantial in facilities with lower direct care staff hours per resident and with likely more immigrants without citizenship. Language barriers tend to be a minor issue when providing essential care. The findings suggest that creating a policy framework that directs immigrant labor to the long-term care sector can mutually benefit job-seeking immigrants and nursing home residents.

Claims-Based vs Agency-Reported Patient Outcomes Among Home Health Agencies, 2013-2019.

Importance: Given the growth of home health agency (HHA) care, it is important to understand whether quality reporting programs, such as star ratings, are associated with improved patient outcomes. Objective: To assess the immediate and long-term association of the introduction of HHA star ratings with patient-level quality outcomes, comparing claims-based and agency-reported measures. Design, Setting, and Participants: This cross-sectional study used Medicare HHA claims and agency-reported assessments to identify sequential patient episodes (ie, spells) among US adults with traditional Medicare who received HHA care (2013-2019). An interrupted time series (ITS) model was used to measure changes in trends and levels before and after the introduction of star ratings. Statistical analysis was performed from November 2022 to September 2023. Exposure: The exposure was the introduction of HHA star ratings. The postexposure period was set as starting January 1, 2016, to account for the period when both star ratings (quality of patient care and patient satisfaction rating) were publicly reported. Main Outcomes and Measures: The main outcomes included claims-based hospitalization measures (both during the patient spell and 30 days after HHA discharge) and agency-reported functional measures, such as improvement in ambulation, bathing, and bed transferring. There was also a measure to capture timely initiation of care among post-acute care HHA users, defined as HHA care initiated within 2 days of inpatient discharge. Results: This study identified 22 958 847 patient spells to compare annual changes over time; 9 750 689 patient spells were included during the pre-star ratings period from January 1, 2013, to December 31, 2015 (6 067 113 [62.2%] female; 1 100 145 [11.3%] Black, 512 487 [5.3%] Hispanic, 7 845 197 [80.5%] White; 2 656 124 [27.2%] dual eligible; mean [SD] patient spell duration, 70.9 [124.9] days; mean [SD] age, 77.4 [12.0] years); 13 208 158 patient spells were included during the post-star ratings period from January 1, 2016, to December 31, 2019 (8 104 69 [61.4%] female; 1 385 180 [10.5%] Black, 675 536 [5.1%] Hispanic, 10 664 239 [80.7%] White; 3 318 113 [25.1%] dual eligible; mean [SD] patient spell duration, 65.3 [96.2] days; mean [SD] age, 77.7 [11.6] years). Results from the ITS models found that the introduction of star ratings was associated with an acceleration in the mean [SE] hospitalization rate during the spell (0.39% [0.05%] per year) alongside functional improvements in ambulation (2.40% [0.29%] per year), bed transferring (3.95% [0.48%] per year) and bathing (2.34% [0.19%] per year) (P < .001). This occurred alongside a 1.21% (0.12%) per year reduction in timely initiation of care (P < .001). Conclusions and Relevance: This cross-sectional study found an observed improvement in agency-reported functional measures, which contrasted with slower increases in more objective measures such as hospitalization rates and declines in timely initiation of care. These findings suggest a complex picture of HHA quality of care after the introduction of star ratings.

Preferences for Postacute Care at Home vs Facilities.

Importance: Two in 5 US hospital stays result in rehabilitative postacute care, typically through skilled nursing facilities (SNFs) or home health agencies (HHAs). However, a lack of clear guidelines and understanding of patient and caregiver preferences make it challenging to promote high-value patient-centered care. Objective: To assess preferences and willingness to pay for facility-based vs home-based postacute care among patients and caregivers, considering demographic variations. Design, Setting, and Participants: In September 2022, a nationally representative survey was conducted with participants 45 years or older. Using a discrete choice experiment, participants acting as patients or caregivers chose between facility-based and home-based postacute care that best met their preferences, needs, and family conditions. Survey weights were applied to generate nationally representative estimates. Main Outcomes and Measures: Preferences and willingness to pay for various attributes of postacute care settings were assessed, examining variation based on demographic factors, socioeconomic status, job security, and previous care experiences. Results: A total of 2077 adults were invited to participate in the survey; 1555 (74.9%) completed the survey. In the weighted sample, 52.9% of participants were women, 6.5% were Asian or Pacific Islander, 1.7% were American Indian or Alaska Native, 11.2% were Black or African American, 78.4% were White; the mean (SD) age was 62.6 (9.6) years; and there was a survey completion rate of 74.9%. Patients and caregivers showed a substantial willingness to pay for home-based and high-quality care. Patients and caregivers were willing to pay an additional $58.08 per day (95% CI, 45.32-70.83) and $45.54 per day (95% CI, 31.09-59.99) for HHA care compared with a shared SNF room, respectively. However, increased demands on caregiver time within an HHA scenario and socioeconomic challenges, such as insecure employment, shifted caregivers' preferences toward facility-based care. There was a strong aversion to below average quality. To avoid below average SNF care, patients and caregivers were willing to pay $75.21 per day (95% CI, 61.68-88.75) and $79.10 per day (95% CI, 63.29-94.91) compared with average-quality care, respectively. Additionally, prior awareness and experience with postacute care was associated with willingness to pay for home-based care. No differences in preferences among patients and caregivers based on race, educational background, urban or rural residence, general health status, or housing type were observed. Conclusions and Relevance: The findings of this survey study underscore a prevailing preference for home-based postacute care, aligning with current policy trends. However, attention is warranted for disadvantaged groups who are potentially overlooked during the shift toward home-based care, particularly those facing caregiver constraints and socioeconomic hardships. Ensuring equitable support and improved quality measure tools are crucial for promoting patient-centric postacute care, with emphasis on addressing the needs of marginalized groups.

New CMS Nursing Home Ownership Data: Major Gaps And Discrepancies.

Nursing home ownership has become increasingly complicated, partly because of the growth of facilities owned by institutional investors such as private equity (PE) firms and real estate investment trusts (REITs). Although the ownership transparency and accountability of nursing homes have historically been poor, the Biden administration's nursing home reform plans released in 2022 included a series of data releases on ownership. However, our evaluation of the newly released data identified several gaps: One-third of PE and fewer than one-fifth of REIT investments identified in the proprietary Irving Levin Associates and S&P Capital IQ investment data were present in Centers for Medicare and Medicaid Services (CMS) publicly available ownership data. Similarly, we obtained different results when searching for the ten top common owners of nursing homes using CMS data and facility survey reports of chain ownership. Finally, ownership percentages were missing in the CMS data for 82.40 percent of owners in the top ten chains and 55.21 percent of owners across all US facilities. Although the new data represent an important step forward, we highlight additional steps to ensure that the data are timely, accurate, and responsive. Transparent ownership data are fundamental to understanding the adequacy of public payments to provide patient care, enable policy makers to make timely decisions, and evaluate nursing home quality.

Administrator Perspectives on the Impact of COVID-19 on the Administration of the Patient Driven Payment Model in U.S. Skilled Nursing Facilities.

The Patient Driven Payment Model (PDPM) was implemented in U.S. skilled nursing facilities (SNFs) in October 2019, shortly before COVID-19. This new payment model aimed to reimburse SNFs for patients' nursing needs rather than the previous model which reimbursed based on the volume of therapy received. Through 156 semi-structured interviews with 40 SNF administrators from July 2020 to December 2021, this qualitative study clarifies the impact of COVID-19 on the administration of PDPM at SNFs. Interview data were analyzed using modified grounded theory and thematic analysis. Our findings show that SNF administrators shifted focus from management of the PDPM to COVID-19-related delivery of care adaptations, staff shortfalls, and decreased admissions. As the pandemic abated, administrators re-focused their attention to PDPM. Policy makers should consider the continued impacts of the pandemic at SNFs, particularly on delivery of care, admissions, and staffing, on the ability of SNF administrators to administer a new payment model.

Nursing Homes Increasingly Rely On Staffing Agencies For Direct Care Nursing.

When nursing homes experience a shortage in directly employed nursing staff, they may rely on temporary workers from staffing agencies to fill this gap. This article examines trends in the use of staffing agencies among nursing homes during the prepandemic and COVID-19 pandemic era (2018-22). In 2018, 23 percent of nursing homes used agency nursing staff, accounting for about 3 percent of all direct care nursing hours worked. When used, agency staff were commonly present for ninety or fewer days in a year. By 2022, almost half of all nursing homes used agency staff, accounting for 11 percent of all direct care nursing staff hours. Agency staff were increasingly used to address chronic staffing shortages, with 13.8 percent of nursing homes having agency staff present every day. Agency staff were 50-60 percent more expensive per hour than directly employed nursing staff, and nursing homes that used agency staff often had lower five-star ratings. Policy makers need to consider postpandemic changes to the nursing home workforce as part of nursing home reform, as increased reliance on agency staff may reduce the financial resources available to increase nursing staff levels and improve the quality of care.

Clinical Risk and Outpatient Therapy Utilization for COVID-19 in the Medicare Population.

Importance: Multiple therapies are available for outpatient treatment of COVID-19 that are highly effective at preventing hospitalization and mortality. Although racial and socioeconomic disparities in use of these therapies have been documented, limited evidence exists on what factors explain differences in use and the potential public health relevance of these differences. Objective: To assess COVID-19 outpatient treatment utilization in the Medicare population and simulate the potential outcome of allocating treatment according to patient risk for severe COVID-19. Design, Setting, and Participants: This cross-sectional study included patients enrolled in Medicare in 2022 across the US, identified with 100% Medicare fee-for-service claims. Main Outcomes and Measures: The primary outcome was any COVID-19 outpatient therapy utilization. Secondary outcomes included COVID-19 testing, ambulatory visits, and hospitalization. Differences in outcomes were estimated based on patient demographics, treatment contraindications, and a composite risk score for mortality after COVID-19 based on demographics and comorbidities. A simulation of reallocating COVID-19 treatment, particularly with nirmatrelvir, to those at high risk of severe disease was performed, and the potential COVID-19 hospitalizations and mortality outcomes were assessed. Results: In 2022, 6.0% of 20 026 910 beneficiaries received outpatient COVID-19 treatment, 40.5% of which had no associated COVID-19 diagnosis within 10 days. Patients with higher risk for severe disease received less outpatient treatment, such as 6.4% of those aged 65 to 69 years compared with 4.9% of those 90 years and older (adjusted odds ratio [aOR], 0.64 [95% CI, 0.62-0.65]) and 6.4% of White patients compared with 3.0% of Black patients (aOR, 0.56 [95% CI, 0.54-0.58]). In the highest COVID-19 severity risk quintile, 2.6% were hospitalized for COVID-19 and 4.9% received outpatient treatment, compared with 0.2% and 7.5% in the lowest quintile. These patterns were similar among patients with a documented COVID-19 diagnosis, those with no claims for vaccination, and patients who are insured with Medicare Advantage. Differences were not explained by variable COVID-19 testing, ambulatory visits, or treatment contraindications. Reallocation of 2022 outpatient COVID-19 treatment, particularly with nirmatrelvir, based on risk for severe COVID-19 would have averted 16 503 COVID-19 deaths (16.3%) in the sample. Conclusion: In this cross-sectional study, outpatient COVID-19 treatment was disproportionately accessed by beneficiaries at lower risk for severe infection, undermining its potential public health benefit. Undertreatment was not driven by lack of clinical access or treatment contraindications.

Nursing Home Staffing: Share Of Immigrant Certified Nursing Assistants Grew As US-Born Staff Numbers Fell, 2010-21.

Nursing homes have long faced a shortage of direct care workers, a problem that was magnified during the COVID-19 pandemic. Using nationally representative data from three sources, we found that much of the certified nursing assistant (CNA) workforce in US nursing homes is filled by immigrant labor. The number of native-born CNAs has been declining rapidly since the mid-2010s, whereas the number of foreign-born CNAs has remained relatively constant. During the first two years of the COVID-19 pandemic, the share of immigrant CNAs employed by nursing homes surged, which can be explained by a simultaneous drop in the share of native-born staff. Staffing shortages observed during the pandemic would have been worse if not for foreign-born CNAs remaining in the workforce. However, the share of foreign-born CNAs varied considerably across states, from less than 1 percent in West Virginia to more than 70 percent in Hawaii. In an analysis of prepandemic data, we found that nursing homes in regions with a higher share of immigrant CNAs were associated with more direct care staff hours per resident day and better nursing home quality performance. With the growing demand for long-term care, creating pathways for job-seeking immigrants to fill the gaps in direct care will be crucial to meeting future staffing needs.

Post-Acute Care in China: Development, Challenges, and Path Forward.

OBJECTIVES: To evaluate the evolution and challenges of China's post-acute care (PAC) system over the past 20 years and suggest actionable policy recommendations for its improvement. DESIGN: A retrospective review of policies and initiatives aimed at PAC system development, analyzed alongside unsolved challenges in light of global PAC practices, informed by literature reviews and collaborative discussion. SETTING AND PARTICIPANTS: PAC in China involves diverse settings such as general hospitals, inpatient rehabilitation centers, skilled nursing facilities, community health centers, and homes. The patients are mainly those discharged from acute hospitals with functional impairment and in need of continuous care. METHOD: An extensive search of government policy documents, statistical sources, peer-reviewed studies, and the gray literature. The research team conducted literature reviews and discussions regularly to shape the findings. RESULTS: China has strengthened its PAC system through improved rehabilitation and nursing infrastructure, establishment of tiered rehabilitation networks, and adoption of innovative payment methods. However, challenges persist, including a lack of clinical consensus, resource constraints in PAC facilities and among professionals, the need for integrated care coordination, and the unification of PAC assessment tools and payment mechanisms. CONCLUSIONS AND IMPLICATIONS: Although China has made substantial progress in its PAC system over 2 decades, continued efforts are needed to address its lingering challenges. Elevating awareness of PAC's significance and instituting policy adjustments targeting these challenges are essential for the system's optimization.

Impact of dementia special care units for short-stay nursing home patients.

BACKGROUND: Improving quality of care provided to short-stay patients with dementia in nursing homes is a policy priority. However, it is unknown whether dementia-focused care strategies are associated with improved clinical outcomes or lower utilization and costs for short-stay dementia patients. METHODS: We performed a national survey of nursing home administrators in 2020-2021, asking about the presence of three dementia-focused care services used for their short-stay patients: (1) a dementia care unit, (2) cognitive deficiency training for staff, and (3) dementia-specific occupational therapy. Using Medicare claims, we identified short-stay episodes for beneficiaries residing in surveyed skilled nursing facilities (SNFs) with and without dementia. We compared clinical, cost, and utilization outcomes for dementia patients in SNFs, which did and did not offer dementia-focused care services. As a counterfactual control, we compared these differences to those for non-dementia patients in the same facilities. Our primary quantity of interest was an interaction term between a patients' dementia status and the presence of a dementia-focused care tool. RESULTS: The study population included 102,860 Medicare episodes of care from 377 SNF survey respondents in 2018-2019. In adjusted comparisons of the interaction between dementia status and the presence of each dementia-focused care tool, dementia care units were associated with a 1.5-day increase in healthy days at home in the 90 days following discharge (p = 0.01) and a 3.1% decrease in the likelihood of a subsequent SNF admission (p = 0.001). Cognitive deficiency training was also associated with a 2.0% increase in antipsychotics (p = 0.03), whereas dementia-specific occupational therapy was associated with a 1.2% increase in falls (p = 0.01) per patient episode. CONCLUSIONS: Self-reported use of dementia care units for short-stay patients was associated with modestly better performance in some, but not all, outcome measures. This provides hypothesis-generating evidence that dementia care units could be a promising mechanism to improve care delivery in nursing homes.

Changes in Care Associated With Integrating Medicare and Medicaid for Dual-Eligible Individuals.

Importance: There is growing interest in expanding integrated models, in which 1 insurer manages Medicare and Medicaid spending for dually eligible individuals. Fully integrated dual-eligible special needs plans (FIDE-SNPs) are one of the largest integrated models, but evidence about their performance is limited. Objective: To evaluate changes in care associated with integrating Medicare and Medicaid coverage in a FIDE-SNP in Pennsylvania. Design, Setting, and Participants: This cohort study using a difference-in-differences analysis compared changes in care between 2 cohorts of dual-eligible individuals: (1) an integration cohort composed of Medicare Dual Eligible Special Needs Plan enrollees who joined a companion Medicaid plan following a 2018 state reform mandating Medicaid managed care (leading to integration), and (2) a comparison cohort with nonintegrated coverage before and after the start of Medicaid managed care. Analyses were conducted between February 2022 and June 2023. Main Outcomes and Measures: Analyses examined outcomes in 4 domains: use of home- and community-based services (HCBS), care management and coordination, hospital stays and postacute care, and long-term nursing home stays. Results: The study included 7967 individuals in the integration cohort and 3832 individuals in the comparison cohort. In the integration cohort, the mean (SD) age at baseline was 63.3 (14.7) years, and 5268 individuals (66.1%) were female and 2699 (33.9%) were male. In the comparison cohort, the mean (SD) age at baseline was 64.8 (18.6) years, and 2341 individuals (61.1%) were female and 1491 (38.9%) were male. At baseline, integration cohort members received a mean (SD) of 2.83 (8.70) days of HCBS per month and 3.34 (3.56) medications for chronic conditions per month, and the proportion with a follow-up outpatient visit after a hospital stay was 0.47. From baseline through 3 years after integration, HCBS use increased differentially in the integration vs comparison cohorts by 0.61 days/person-month (95% CI, 0.28-0.94; P < .001). However, integration was not associated with changes in care management and coordination, including medication use for chronic conditions (-0.02 fills/person-month; 95% CI, -0.10 to 0.06; P = .65) or follow-up outpatient care after a hospital stay (-0.01 visits/hospital stay; 95% CI, -0.04 to 0.03; P = .61). Hospital stays did not change differentially between the cohorts. Unmeasured factors contributing to differential mortality limited the ability to identify changes in long-term nursing home stays associated with integration. Conclusions and Relevance: In this cohort study with a difference-in-differences analysis of 2 cohorts of individuals dually eligible for Medicare and Medicaid, integration was associated with greater HCBS use but not with other changes in care patterns. The findings highlight opportunities to strengthen how integrated programs manage care and a need to further evaluate their performance.
