The Evolving Practice of Hospital at Home in the United States.

Hospital at Home (HaH) provides hospital-level services in the home to eligible patients who would otherwise require facility-based hospitalization. In the last two decades, studies have shown that HaH can improve patient outcomes and satisfaction and reduce hospital readmissions. Improved technology and greater experience with the model have led to expansion in the scope of patients served and services provided by the model, but dissemination in the United States has been hampered by lack of insurance coverage until recently. HaH is likely at the tipping point for wide adoption in the United States. To realize its full benefits, HaH will need to continue volume expansion to achieve culture change in clinical practice as facilitated by increased insurance coverage, technological advancements, and improved workforce expertise. It is also essential that HaH programs maintain high-quality acute hospital care, ensure that their benefits can be accessed by hard-to-reach rural populations, and continue to advance health equity.

Effects of a Rehabilitation-at-Home Program Compared to Post-acute Skilled Nursing Facility Care on Safety, Readmission, and Community Dwelling Status: A Matched Cohort Analysis.

OBJECTIVES: To evaluate the effectiveness and safety of Rehabilitation-at-Home (RaH), which provides high-frequency, multidisciplinary post-acute rehabilitative services in patients' homes. DESIGN: Comparative effectiveness analysis. SETTING AND PARTICIPANTS: Medicare Fee-For-Service patients who received RaH in a Center for Medicare and Medicaid Innovation Center Demonstration during 2016-2017 (N=173) or who received Medicare Skilled Nursing Facility (SNF) care in 2016-2017 within the same geographic service area with similar inclusion and exclusion criteria (N=5535). METHODS: We propensity-matched RaH participants to a cohort of SNF patients using clinical and demographic characteristics with exact match on surgical and non-surgical hospitalizations. Outcomes included hospitalization within 30 days of post-acute admission, death within 30 days of post-acute discharge, length of stay, falls, use of antipsychotic medication, and discharge to community. RESULTS: The majority of RaH participants were older than or equal to 85 years (57.8%) and non-Hispanic white (72.2%) with mean hospital length of stay of 8.1 (SD 7.6) days. In propensity-matched analyses, 10.1% (95% CI: 0.5%, 19.8) and 4.2% (95% CI: 0.1%, 8.5%) fewer RaH participants experienced hospital readmission and death, respectively. RaH participants had, on average, 2.8 fewer days (95% CI 1.4, 4.3) of post-acute care; 11.4% (95% CI: 5.2%, 17.7%) fewer RaH participants experienced fall; and 25.8% (95% CI: 17.8%, 33.9%) more were discharged to the community. Use of antipsychotic medications was no different. CONCLUSIONS AND IMPLICATIONS: RaH is a promising alternative to delivering SNF-level post-acute RaH. The program seems to be safe, readmissions are lower, and transition back to the community is improved.

Outcomes of home-based primary care for homebound older adults: A randomized clinical trial.

BACKGROUND: Homebound older adults are medically complex and often have difficulty accessing outpatient medical care. Home-based primary care (HBPC) may improve care and outcomes for this population but data from randomized trials of HBPC in the United States are limited. METHODS: We conducted a randomized controlled trial of HBPC versus office-based primary care for adults ages ≥65 years who reported ≥1 hospitalization in the prior 12 months and met the Medicare definition of homebound. HBPC was provided by teams consisting of a physician, nurse practitioner, nurse, and social worker. Data were collected at baseline, 6- and 12-months. Outcomes were quality of life, symptoms, satisfaction with care, hospitalizations, and emergency department (ED) visits. Recruitment was terminated early because more deaths were observed for intervention patients. RESULTS: The study enrolled 229 patients, 65.4% of planned recruitment. The mean age was 82 (9.0) years and 72.3% had dementia. Of those assigned to HBPC, 34.2% never received it. Intervention patients had greater satisfaction with care than controls (2.26, 95% CI 1.46-3.06, p < 0.0001; effect size 0.74) and lower hospitalization rates (-17.9%, 95% CI -31.0% to -1.0%; p = 0.001; number needed to treat 6, 95% CI 3-100). There were no significant differences in quality of life (1.25, 95% CI -0.39-2.89, p = 0.13), symptom burden (-1.92, 95% CI -5.22-1.37, p = 0.25) or ED visits (1.2%, 95% CI -10.5%-12.4%; p = 0.87). There were 24 (21.1%) deaths among intervention patients and 12 (10.7%) among controls (p < 0.0001). CONCLUSION: HBPC was associated with greater satisfaction with care and lower hospitalization rates but also more deaths compared to office-based primary care. Additional research is needed to understand the nature of the higher death rate for HBPC patients, as well as to determine the effects of HBPC on quality of life and symptom burden given the trial's early termination.

Hospital-at-Home: Multistakeholder Considerations for Program Dissemination and Scale.

Policy Points Hospital-at-Home (HaH) is a home-based alternative for acute care that has expanded significantly under COVID-19 regulatory flexibilities. The post-pandemic policy agenda for HaH will require consideration of multistakeholder perspectives, including patient, caregiver, provider, clinical operations, technology, equity, legal, quality, and payer. Key policy challenges include reaching a consensus on program standards, clarifying caregivers' issues, creating sustainable reimbursement mechanisms, and mitigating potential equity concerns. Key policy prescriptions include creating a national surveillance system for quality and safety, clarifying legal standards for care in the home, and deploying payment reforms through value-based models.

Effect of the STRIDE fall injury prevention intervention on falls, fall injuries, and health-related quality of life.

BACKGROUND: Falls are common in older adults and can lead to severe injuries. The Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) trial cluster-randomized 86 primary care practices across 10 health systems to a multifactorial intervention to prevent fall injuries, delivered by registered nurses trained as falls care managers, or enhanced usual care. STRIDE enrolled 5451 community-dwelling older adults age ≥70 at increased fall injury risk. METHODS: We assessed fall-related outcomes via telephone interviews of participants (or proxies) every 4 months. At baseline, 12 and 24 months, we assessed health-related quality of life (HRQOL) using the EQ-5D-5L and EQ-VAS. We used Poisson models to assess intervention effects on falls, fall-related fractures, fall injuries leading to hospital admission, and fall injuries leading to medical attention. We used hierarchical longitudinal linear models to assess HRQOL. RESULTS: For recurrent event models, intervention versus control incidence rate ratios were 0.97 (95% confidence interval [CI], 0.93-1.00; p = 0.048) for falls, 0.93 (95% CI, 0.80-1.08; p = 0.337) for self-reported fractures, 0.89 (95% CI, 0.73-1.07; p = 0.205) for adjudicated fractures, 0.91 (95% CI, 0.77-1.07; p = 0.263) for falls leading to hospital admission, and 0.97 (95% CI, 0.89-1.06; p = 0.477) for falls leading to medical attention. Similar effect sizes (non-significant) were obtained for dichotomous outcomes (e.g., participants with ≥1 events). The difference in least square mean change over time in EQ-5D-5L (intervention minus control) was 0.009 (95% CI, -0.002 to 0.019; p = 0.106) at 12 months and 0.005 (95% CI, -0.006 to 0.015; p = 0.384) at 24 months. CONCLUSIONS: Across a standard set of outcomes typically reported in fall prevention studies, we observed modest improvements, one of which was statistically significant. Future work should focus on patient-, practice-, and organization-level operational strategies to increase the real-world effectiveness of interventions, and improving the ability to detect small but potentially meaningful clinical effects.

Use of hospitals in the New York City Metropolitan Region, by race: how separate? How equal in resources and quality?

BACKGROUND: Although racial and ethnic minorities disproportionately use some hospitals, hospital-based racial and ethnic composition relative to geographic region and its association with quality indicators has not been systematically analyzed. METHODS: We used four race and ethnicity categories: non-Hispanic white (NHW), non-Hispanic black (NHB), Hispanic, and Asian/Pacific Islander/Alaskan Native/American Indian (API/AIAN), as well as a combined non-NHW category, from the 2010 (latest year publicly available) Medicare Institutional Provider & Beneficiary Summary public use file for 84 hospitals in the New York City region. We assessed the relative distribution of race and ethnicity across hospitals grouped at different geographic levels (region, county, hospital referral region [HRR], or hospital service areas [HSA]) using the dissimilarity index. Hospital characteristics included quality star ratings, essential professional services and diagnostic/treatment equipment, bed size, total expenses, and patients with dual Medicare and Medicaid enrollment. We assessed Spearman's rank correlation between hospital-based racial and ethnic composition and quality/structural measures. RESULTS: Dissimilarity Index decreases from region (range 30.3-40.1%) to county (range 13.7-23.5%), HRR (range 10.5-27.5%), and HSA (range 12.0-16.9%) levels. Hospitals with larger non-NHW patients tended to have lower hospital ratings and higher proportions of dually-enrolled patients. They were also more likely to be safety net hospitals and non-federal governmental hospitals. CONCLUSIONS: In the NYC metropolitan region, there is considerable hospital-based racial and ethnic segregation of Medicare patients among non-NHW populations, extending previous research limited to NHB. Availability of data on racial and ethnic composition of hospitals should be made publicly available for researchers and consumers.

Cost of home hospitalization versus inpatient hospitalization inclusive of a 30-day post-acute period.

BACKGROUND: Previous studies have demonstrated that hospital at home (HaH) care is associated with lower costs than traditional hospital care. Most prior studies were small, not U.S.-focused, or did not include post-acute costs in their analyses. Our objective was to determine if combined acute and 30-day post-acute costs of care were lower for HaH patients compared to inpatient comparisons in a Center for Medicare and Medicaid Innovation Center demonstration of HaH. METHODS: A single-center New York City retrospective observational cohort study of patients admitted to either HaH or inpatient care from September 1, 2014 through August 31, 2017. Eligible patients were 18 years or older, required inpatient admission, lived in Manhattan, and met home safety requirements. Comparison individuals met the same criteria and were included if they refused HaH care or were admitted when HaH was not available. HaH care was substitutive hospital-level care and 30-days of post-acute transitional care. Main outcomes were costs of care of the acute and post-acute 30-day episodes. We matched subjects on age, sex, and insurance and conducted regression analyses using an unadjusted model and one adjusted for several patient characteristics. RESULTS: Of 523 Medicare admission episodes, data were available for 201 episodes in the HaH arm and 101 episodes of usual care. HaH patients were older (81.6 [SD = 12.3] years vs. 74.6 [SD = 14.0], p < 0.0001) and more likely to have activities of daily living (ADL) impairments (75.4% vs. 46.5%, p < 0.0001). Unadjusted mean costs were $5054 lower for HaH episodes compared to inpatient episodes. Regression analysis with matching showed HaH costs were $5116 (95% CI -$10,262 to $30, p = 0.05) lower, and when adjusted for age, sex, insurance, diagnosis, and ADL impairments, $5977 (95% CI -$10,758 to -$1196, p = 0.01) lower. CONCLUSIONS: HaH combined with 30-day post-acute transition care was less costly than inpatient care.

Medicare-funded home-based clinical care for community-dwelling persons with dementia: An essential healthcare delivery mechanism.

BACKGROUND: Over the past decade, medical care has shifted from institutions into home settings-particularly among persons with dementia. Yet it is unknown how home-based clinical services currently support persons with dementia, and what factors shape access. METHODS: Using the National Health and Aging Trends Study linked to Medicare claims 2012-2017, we identified 6664 community-dwelling adults age ≥ 70 years enrolled in fee-for-service Medicare. Annual assessment of dementia status was determined via self-report, cognitive interview, and/or proxy assessment. Receipt of four types of home-based clinical care (home-based medical care (HBMC) (i.e., nurse practitioner, physician, or physician assistant visits), skilled home health care (SHHC), podiatry visits, and other types of home-based clinical services (e.g., behavioral health)) was assessed annually. We compared age-adjusted rates of home-based clinical care by dementia status and determined sociodemographic, health, and environmental characteristics associated with utilization of home-based clinical care among persons with dementia. RESULTS: Nearly half (44.4%) of persons with dementia received any home-based clinical care annually compared to only 14.4% of those without dementia. Persons with dementia received substantially more of each type of home-based clinical care than those without dementia including a 5-fold increased use of HBMC (95% CI = 3.8-6.2) and double the use of SHHC (95% CI = 2.0-2.5). In adjusted models, Hispanic/Latino persons with dementia were less likely to receive HBMC (OR = 0.32; 95% CI = 0.11-0.93). Use of HBMC, podiatry, and other home-based clinical care was significantly more likely among those living in residential care facilities, in the Northeast and in metropolitan areas. CONCLUSION: Although almost half of community-dwelling persons with dementia receive home-based clinical care, there is significant variation in utilization based on race/ethnicity and environmental context. Increased understanding as to how these factors impact utilization is necessary to reduce potential inequities in healthcare delivery among the dementia population.

Outcomes of Hospital at Home for Older Adults with and without High Levels of Social Support.

The evaluation of social support within hospital at home (HaH) programs has been limited. We performed a secondary analysis of a prospective cohort evaluation of 295 participants receiving HaH care and 212 patients undergoing traditional hospitalization from November of 2014 to August of 2017. We examined the confounding and moderating effects of instrumental and informational social support upon length of stay and 30-day rehospitalization, emergency department (ED) visit, and skilled nursing facility admission. Instrumental social support attenuated the effects of HaH upon any ED visit (base model: OR 0.61, p = 0.037; controlling for social support: OR 0.71, p = 0.15). The association of HaH with other outcomes remained unchanged. Interactions between HaH and informational or instrumental social support for all outcomes were not significant. Lack of high levels of social support had little effect on the positive outcomes of HaH care, suggesting similar benefits of HaH services for patients with lower levels of social support.

Disruptions in Care and Support for Homebound Adults in Home-Based Primary Care in New York City During the COVID-19 Pandemic.

Homebound older adults are a highly vulnerable population, yet little is known about their experiences with healthcare during the COVID-19 pandemic. We interviewed patients in home-based primary care (HBPC) in New York City by telephone in May and June of 2020. Interviews covered social supports, household activities, self-care, and medical care, and asked participants to compare current with prepandemic experiences. Among 70 participants, 37% were Black and 32% were Hispanic. Disruptions in the home included greater difficulty accessing paid caregivers (13.9%) and food (35.3%) than before the pandemic, and unaddressed household chores (laundry, 81.4%; food preparation, 11.4%). Black study participants were more likely than White and Hispanic participants to report disruptions in accessing medical care (13 [50.0%] vs. 3 [14.3%] vs. 6 [27.3%], respectively, p = 0.02), as well as food preparation and medication taking. Black patients in HBPC are at risk of disparities in healthcare and social support during the COVID-19 pandemic.

Hospital at Home services: An inventory of fee-for-service payments to inform Medicare reimbursement.

BACKGROUND: Hospital at Home (HaH) is a growing model of care with proven patient benefits. However, for the types of services required to provide an episode of HaH, full Medicare reimbursement is traditionally paid only if care is provided in inpatient facilities. DESIGN: This project identifies HaH services that could be reimbursable under Medicare to inform episodic care within fee-for-service (FFS) Medicare. SETTING: All data are derived from acute services provided from the Mount Sinai HaH program between 2014 and 2017 as part of a Center for Medicare and Medicaid Innovation (CMMI) demonstration program. PARTICIPANTS: The sample was limited to patients with one of the following five admitting diagnoses: urinary tract infection (n = 70), pneumonia (n = 60), cellulitis (n = 45), heart failure (n = 37), and chronic lung disease (n = 24) for a total of 236 acute episodes. MEASUREMENTS: HaH services were inventoried from three sources: electronic medical records, Medicare billing and itemized vendor billing. For each admitting diagnosis, four reimbursement scenarios were evaluated: (1) FFS Medicare without a home health episode, (2) FFS Medicare with a home health episode, (3) two-sided risk ACO with a home health episode, and (4) two-sided risk ACO without a home health episode. RESULTS: Across diagnoses, there were 1.5-1.9 MD visits and 1.5-2.7 nursing visits per episode. The Medicare FFS model without home health care had the lowest reimbursement potential ($964-$1604) per episode. The Medicare fee-for-service within ACO models with home health care had the greatest potential for reimbursement $4519-$4718. There was limited variation in costs by diagnosis. CONCLUSION AND RELEVANCE: Though existing payment models might be used to pay for many HaH acute services, significant gaps in reimbursement remain. Extending the benefits of HaH to the Medicare beneficiaries that are likely to derive the greatest benefit will require new payment models for FFS Medicare.

Barriers to implementation of STRIDE, a national study to prevent fall-related injuries.

BACKGROUND/OBJECTIVES: Evaluations of complex models of care for older adults may benefit from simultaneous assessment of intervention implementation. The STRIDE (Strategies To Reduce Injuries and Develop confidence in Elders) pragmatic trial evaluated the effectiveness of a multifactorial intervention to reduce serious fall injuries in older adults. We conducted multi-level stakeholder interviews to identify barriers to STRIDE intervention implementation and understand efforts taken to mitigate these barriers. DESIGN: Qualitative interviews with key informants. SETTING: Ten clinical trial sites affiliated with practices that provided primary care for persons at increased risk for fall injuries. PARTICIPANTS: Specially trained registered nurses working as Falls Care Managers (FCMs) who delivered the intervention (n = 13 individual interviews), Research Staff who supervised trial implementation locally (n = 10 group interviews, 23 included individuals), and members of Central Project Management and the National Patient Stakeholder Council who oversaw national implementation (n = 2 group interviews, six included individuals). MEASUREMENTS: A semi-structured interview guide derived from the consolidated framework for implementation research (CFIR). RESULTS: We identified eight key barriers to STRIDE intervention implementation. FCMs navigated complex relationships with patients and families while working with Research Staff to implement the intervention in primary care practices with limited clinical space, variable provider buy-in, and significant primary care practice staff and provider turnover. The costs of the intervention to individual patients and medical practices amplified these barriers. Efforts to mitigate these barriers varied depending on the needs and opportunities of each primary care setting. CONCLUSION: The many barriers to implementation and the variability in how stakeholders addressed these locally may have affected the overall STRIDE intervention's effectiveness. Future pragmatic trials should incorporate simultaneous implementation aims to better understand how research interventions translate into clinical care that improves the lives of older adults.

A Multi-Phase Quality Improvement Initiative for the Treatment of Active Delirium in Older Persons.

BACKGROUND/OBJECTIVES: The Hospital Elder Life Program emerged 20 years ago as the reference model for delirium prevention in hospitalized older patients. However, implementation has been achieved at only 200 hospitals worldwide over the last 20 years. Among the barriers to implementation for some institutions is an unwillingness of hospital administration to assume the costs associated with implementing programs that service all hospitalized older patients at risk for delirium. Facing such a situation, we implemented a unique and self-evolving model of care of older hospitalized patients who had already developed delirium. DESIGN: Hypothesis testing was carried out using a pretest-posttest design on program administrative data. SETTING: Mount Sinai Hospital, New York, NY, a tertiary-care teaching facility. PARTICIPANTS A total of 9,214 consecutively admitted older patients to non-intensive care (ICU) inpatient units over a 5.5-year period, regardless of the suspected presence of delirium or risk status for developing delirium. INTERVENTION: A delirium intervention program targeting patients in whom delirium has already developed, with a modified delirium team supported by extensive workflow automation with custom tools in our electronic medical records system. MEASUREMENTS: Length of stay (LOS) for delirious and non-delirious patients on units where this program was piloted. Benzodiazepine, opiate, and antipsychotic use on the same units. RESULTS: There was a significant drop in LOS by 1.98 days (95% confidence interval = .24-3.71), a decrease in the average morphine dose equivalents administered from .38 mg to .21 mg per patient hospital day, diazepam dose equivalents from .22 mg to .15 mg per patient hospital day, and quetiapine administered from .17 mg to .14 mg per patient hospital day for delirious patients on the program pilot units. CONCLUSION: Elements of our unique active delirium treatment program may provide some direction to other program developers working on improving the care of older hospitalized delirious patients. However, the supporting evidence presented is limited, and a more rigorous prospective study is needed.

Association of Geographic Differences in Prevalence of Uncontrolled Chronic Conditions With Changes in Individuals' Likelihood of Uncontrolled Chronic Conditions.

Importance: The prevalence of leading risk factors for morbidity and mortality in the US significantly varies across regions, states, and neighborhoods, but the extent these differences are associated with a person's place of residence vs the characteristics of the people who live in different places remains unclear. Objective: To estimate the degree to which geographic differences in leading risk factors are associated with a person's place of residence by comparing trends in health outcomes among individuals who moved to different areas or did not move. Design, Setting, and Participants: This retrospective cohort study estimated the association between the differences in the prevalence of uncontrolled chronic conditions across movers' destination and origin zip codes and changes in individuals' likelihood of uncontrolled chronic conditions after moving, adjusting for person-specific fixed effects, the duration of time since the move, and secular trends among movers and those who did not move. Electronic health records from the Veterans Health Administration were analyzed. The primary analysis included 5 342 207 individuals with at least 1 Veterans Health Administration outpatient encounter between 2008 and 2018 who moved zip codes exactly once or never moved. Exposures: The difference in the prevalence of uncontrolled chronic conditions between a person's origin zip code and destination zip code (excluding the individual mover's outcomes). Main Outcomes and Measures: Prevalence of uncontrolled blood pressure (systolic blood pressure level >140 mm Hg or diastolic blood pressure level >90 mm Hg), uncontrolled diabetes (hemoglobin A1c level >8%), obesity (body mass index >30), and depressive symptoms (2-item Patient Health Questionnaire score ≥2) per quarter-year during the 3 years before and the 3 years after individuals moved. Results: The study population included 5 342 207 individuals (mean age, 57.6 [SD, 17.4] years, 93.9% men, 72.5% White individuals, and 12.7% Black individuals), of whom 1 095 608 moved exactly once and 4 246 599 never moved during the study period. Among the movers, the change after moving in the prevalence of uncontrolled blood pressure was 27.5% (95% CI, 23.8%-31.3%) of the between-area difference in the prevalence of uncontrolled blood pressure. Similarly, the change after moving in the prevalence of uncontrolled diabetes was 5.0% (95% CI, 2.7%-7.2%) of the between-area difference in the prevalence of uncontrolled diabetes; the change after moving in the prevalence of obesity was 3.1% (95% CI, 2.0%-4.2%) of the between-area difference in the prevalence of obesity; and the change after moving in the prevalence of depressive symptoms was 15.2% (95% CI, 13.1%-17.2%) of the between-area difference in the prevalence of depressive symptoms. Conclusions and Relevance: In this retrospective cohort study of individuals receiving care at Veterans Health Administration facilities, geographic differences in prevalence were associated with a substantial percentage of the change in individuals' likelihood of poor blood pressure control or depressive symptoms, and a smaller percentage of the change in individuals' likelihood of poor diabetes control and obesity. Further research is needed to understand the source of these associations with a person's place of residence.

The Association Between Income and Incident Homebound Status Among Older Medicare Beneficiaries.

IMPORTANCE: A large and growing population of older adults with multimorbidity, cognitive impairment, and functional disability live in the community, but many never or rarely leave their homes. Being homebound is associated with decreased access to medical services, poor health outcomes, and increased mortality. Yet, it is unknown what factors, in particular socioeconomic factors, are associated with new onset of homebound status. OBJECTIVE: To evaluate the association between income and risk of becoming homebound. DESIGN: Observational cohort study using 2011 to 2018 data from the National Health and Aging Trends Study, a nationally representative sample of Medicare beneficiaries aged 65 years and older. SETTING: Population-based study in the United States. PARTICIPANTS: A total of 7,042 initially nonhomebound community-dwelling older adults. EXPOSURE: Total annual household income at baseline (in 2011) measured via self-report. OUTCOME: Annual measure of homebound status, defined as leaving home an average of 1 d/wk or less. RESULTS: Over 7 years, 15.81% of older adults in the lowest income quartile (≤$15,003) became homebound, compared with only 4.64% of those in the highest income quartile (>$60,000). In a competing risks analysis accounting for risks of death and nursing home admission, and adjusted for clinical and demographic characteristics, those in the lowest income quartile had a substantially higher subhazard of becoming homebound than those in the highest income quartile (1.65; 95% confidence interval = 1.20-2.29). Moreover, we see evidence of a gradient in risk of homebound status by income quartile. CONCLUSION AND RELEVANCE: Our work demonstrates that financial resources shape the risk of becoming homebound, which is associated with negative health consequences. In the context of existing income disparities, more support is needed to assist older adults with limited financial resources who wish to remain in the community.
