A Scoping Review of Dementia Interventions in Home-Based Primary Care.

OBJECTIVES: Home-based primary care (HBPC) provides interdisciplinary, longitudinal, comprehensive care at home to homebound older adults. The prevalence of dementia among HBPC recipients is approximately 50%. To date, little research has been performed to determine whether dementia-specific interventions have been conducted in HBPC or their efficacy. We performed a scoping review to assess the landscape of dementia interventions in HBPC. DESIGN: Systematic scoping review. SETTING AND PARTICIPANTS: Care delivery programs for patients or caregivers of patients with dementia for the purpose of improving the management of dementia in the setting of HBPC. METHODS: The PRISMA-ScR protocol was followed. Literature searches were performed using PubMed, Embase, and Scopus for articles on dementia-focused interventions implemented in HBPC. Articles were excluded if they consisted of abstracts only, were not in English, or were not dementia interventions in HBPC. RESULTS: A total of 1657 unique titles and abstracts were screened. Overall, 1584 titles and abstracts were excluded, resulting in 73 full-text studies to assess for eligibility. Of these 73 full-text studies, 1 study met criteria for inclusion, an observational study assessing the implementation of the Resources for Enhancing Alzheimer's Caregiver Health (REACH) intervention in Veterans Affairs HBPC. That study found the intervention to be effective in reducing caregiver burden, with a decrease of 2 hours on duty per day, trending toward significance. Among the excluded 72 full-text studies, some studies included potentially relevant interventions that could be translated into HBPC care, including dementia interventions that targeted long-term services and supports, office-based primary care and other nonhome settings such as nursing homes, and home-based palliative care. CONCLUSIONS AND IMPLICATIONS: Despite high prevalence of dementia among homebound older adults receiving HBPC, there are a dearth of studies on HBPC-specific dementia interventions. Future studies should consider adapting and testing interventions found to be effective in other settings to HBPC.

How the Timing of Annual COVID-19 Vaccination of Nursing Home Residents and Staff Affects Its Value.

OBJECTIVES: To evaluate the epidemiologic, clinical, and economic value of an annual nursing home (NH) COVID-19 vaccine campaign and the impact of when vaccination starts. DESIGN: Agent-based model representing a typical NH. SETTING AND PARTICIPANTS: NH residents and staff. METHODS: We used the model representing an NH with 100 residents, its staff, their interactions, COVID-19 spread, and its health and economic outcomes to evaluate the epidemiologic, clinical, and economic value of varying schedules of annual COVID-19 vaccine campaigns. RESULTS: Across a range of scenarios with a 60% vaccine efficacy that wanes starting 4 months after protection onset, vaccination was cost saving or cost-effective when initiated in the late summer or early fall. Annual vaccination averted 102 to 105 COVID-19 cases when 30-day vaccination campaigns began between July and October (varying with vaccination start), decreasing to 97 and 85 cases when starting in November and December, respectively. Starting vaccination between July and December saved $3340 to $4363 and $64,375 to $77,548 from the Centers for Medicare & Medicaid Services and societal perspectives, respectively (varying with vaccination start). Vaccination's value did not change when varying the COVID-19 peak between December and February. The ideal vaccine campaign timing was not affected by reducing COVID-19 levels in the community, or varying transmission probability, preexisting immunity, or COVID-19 severity. However, if vaccine efficacy wanes more quickly (over 1 month), earlier vaccination in July resulted in more cases compared with vaccinating later in October. CONCLUSIONS AND IMPLICATIONS: Annual vaccination of NH staff and residents averted the most cases when initiated in the late summer through early fall, at least 2 months before the COVID-19 winter peak but remained cost saving or cost-effective when it starts in the same month as the peak. This supports tethering COVID vaccination to seasonal influenza campaigns (typically in September-October) for providing protection against SARS-CoV-2 winter surges in NHs.

Characterizing changes to older adults' care transition patterns from hospital to home care in the initial year of COVID-19.

BACKGROUND: Skilled home healthcare (HH) provided in-person care to older adults during the COVID-19 pandemic, yet little is known about the pandemic's impact on HH care transition patterns. We investigated pandemic impact on (1) HH service volume; (2) population characteristics; and (3) care transition patterns for older adults receiving HH services after hospital or skilled nursing facility (SNF) discharge. METHODS: Retrospective, cohort, comparative study of recently hospitalized older adults (≥ 65 years) receiving HH services after hospital or SNF discharge at two large HH agencies in Baltimore and New York City (NYC) 1-year pre- and 1-year post-pandemic onset. We used the Outcome and Assessment Information Set (OASIS) and service use records to examine HH utilization, patient characteristics, visit timeliness, medication issues, and 30-day emergency department (ED) visit and rehospitalization. RESULTS: Across sites, admissions to HH declined by 23% in the pandemic's first year. Compared to the year prior, older adults receiving HH services during the first year of the pandemic were more likely to be younger, have worse mental, respiratory, and functional status in some areas, and be assessed by HH providers as having higher risk of rehospitalization. Thirty-day rehospitalization rates were lower during the first year of the pandemic. COVID-positive HH patients had lower odds of 30-day ED visit or rehospitalization. At the NYC site, extended duration between discharge and first HH visit was associated with reduced 30-day ED visit or rehospitalization. CONCLUSIONS: HH patient characteristics and utilization were distinct in Baltimore versus NYC in the initial year of the COVID-19 pandemic. Study findings suggest some older adults who needed HH may not have received it, since the decrease in HH services occurred as SNF use decreased nationally. Findings demonstrate the importance of understanding HH agency responsiveness during public health emergencies to ensure older adults' access to care.

Cost-effectiveness of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) testing and isolation strategies in nursing homes.

OBJECTIVE: Nursing home residents may be particularly vulnerable to coronavirus disease 2019 (COVID-19). Therefore, a question is when and how often nursing homes should test staff for COVID-19 and how this may change as severe acute respiratory coronavirus virus 2 (SARS-CoV-2) evolves. DESIGN: We developed an agent-based model representing a typical nursing home, COVID-19 spread, and its health and economic outcomes to determine the clinical and economic value of various screening and isolation strategies and how it may change under various circumstances. RESULTS: Under winter 2023-2024 SARS-CoV-2 omicron variant conditions, symptom-based antigen testing averted 4.5 COVID-19 cases compared to no testing, saving $191 in direct medical costs. Testing implementation costs far outweighed these savings, resulting in net costs of $990 from the Centers for Medicare & Medicaid Services perspective, $1,545 from the third-party payer perspective, and $57,155 from the societal perspective. Testing did not return sufficient positive health effects to make it cost-effective [$50,000 per quality-adjusted life-year (QALY) threshold], but it exceeded this threshold in ≥59% of simulation trials. Testing remained cost-ineffective when routinely testing staff and varying face mask compliance, vaccine efficacy, and booster coverage. However, all antigen testing strategies became cost-effective (≤$31,906 per QALY) or cost saving (saving ≤$18,372) when the severe outcome risk was ≥3 times higher than that of current omicron variants. CONCLUSIONS: SARS-CoV-2 testing costs outweighed benefits under winter 2023-2024 conditions; however, testing became cost-effective with increasingly severe clinical outcomes. Cost-effectiveness can change as the epidemic evolves because it depends on clinical severity and other intervention use. Thus, nursing home administrators and policy makers should monitor and evaluate viral virulence and other interventions over time.

Caring for caregivers and persons living with dementia under home-based primary care: protocol for an interventional clinical trial.

BACKGROUND: Approximately 7.5 million older adults are homebound, who have difficulty and/or need assistance to leave their homes. In this growing population, the prevalence of people living with dementia (PLWD) is approximately 50%. Current dementia care models in the USA were developed for traditional office-based primary care and have not been tailored to home-based primary care (HBPC) delivery models. Literature has shown that office-based collaborative interventions can improve caregiver outcomes including caregiver stress, well-being, and morbidity and patient outcomes including improved quality of life and reduced emergency department visits (Possin KL, Merrilees JJ, Dulaney S, Bonasera SJ, Chiong W, Lee K, JAMA Int Med 179:1658, 2019). To date, the evidence for HBPC dementia interventions is lacking. Though HBPC has demonstrated benefit in homebound older adults, there is limited literature on the effects of HBPC on persons living with dementia (Nguyen HQ, Vallejo JD, Macias M, Shiffman MG, Rosen R, Mowry V, J Am Geriatr Soc 70:1136-46, 2021). Our goal is to develop a HBPC-focused dementia care intervention that integrates the components of two previously developed dementia care models and test the feasibility of implementing it in HBPC practices to improve the quality of life and wellbeing of homebound PLWD and their caregivers. METHODS: We will first conduct qualitative focus groups at two HBPC practice sites, one in the Southeast and one in Hawaii in order to obtain preliminary feedback on the proposed intervention. At each site, there will be one focus group with caregivers of PLWD and another with HBPC clinicians and staff to help develop and refine our intervention. We will then conduct an open-pilot trial of the refined intervention at the two HBPC practices. A total of up to 25 patient/caregiver dyads will be recruited at each site (N = 50 total). Outcomes measured through pre-and-post assessments and exit interviews will include (a) feasibility for the caregiver to engage with and complete baseline assessments and access educational materials and community resources and (b) feasibility for the practice to identify potential caregivers/patients, assess eligible patient/caregiver dyads, use patient and caregiver assessments, recruit patient/caregiver dyads, recruit racial and ethnic minorities, use care modules, and engage with the tele-video case conference, (c) net promoter score, (d) acceptability of the intervention to caregivers and patients to participate in the intervention, (e) caregivers feeling heard and understood, and (f) caregiver well-being. DISCUSSION: Testing the feasibility and acceptability of the adapted intervention in these two HBPC practices will provide the basis for future testing and evaluation of a fully powered intervention for PLWD and their caregivers cared for in HBPC with the goal of disseminating high-quality and comprehensive dementia-care focused interventions into HBPC practices. TRIAL REGISTRATION: This trial was registered with ClinicalTrials.gov NCT05849259 in May 2023.

The hospital at home in the USA: current status and future prospects.

The annual cost of hospital care services in the US has risen to over $1 trillion despite relatively worse health outcomes compared to similar nations. These trends accentuate a growing need for innovative care delivery models that reduce costs and improve outcomes. HaH-a program that provides patients acute-level hospital care at home-has made significant progress over the past two decades. Technological advancements in remote patient monitoring, wearable sensors, health information technology infrastructure, and multimodal health data processing have contributed to its rise across hospitals. More recently, the COVID-19 pandemic brought HaH into the mainstream, especially in the US, with reimbursement waivers that made the model financially acceptable for hospitals and payors. However, HaH continues to face serious challenges to gain widespread adoption. In this review, we evaluate the peer-reviewed evidence and discuss the promises, challenges, and what it would take to tap into the future potential of HaH.

Fellowship-trained physicians who let their geriatric medicine certification lapse: A national survey.

BACKGROUND: Only 62.6% of fellowship-trained and American Board of Internal Medicine (ABIM)-certified geriatricians maintain their specialty certification in geriatric medicine, the lowest rate among all internal medicine subspecialties and the only subspecialty in which physicians maintain their internal medicine certification at higher rates than their specialty certification. This study aims to better understand underlying issues related to the low rate of maintaining geriatric medicine certification in order to inform geriatric workforce development strategies. METHODS: Eighteen-item online survey of internists who completed a geriatric medicine fellowship, earned initial ABIM certification in geriatric medicine between 1999 and 2009, and maintained certification in internal medicine (and/or another specialty but not geriatric medicine). Survey domains: demographics, issues related to maintaining geriatric medicine certification, professional identity, and current professional duties. RESULTS: 153/723 eligible completed surveys (21.5% response). Top reasons for not maintaining geriatric medicine certification were time (56%), cost of maintenance of certification (MOC) (45%), low Medicare reimbursement for geriatricians' work (32%), and no employer requirement to maintain geriatric medicine certification (31%). Though not maintaining geriatric medicine certification, 68% reported engaging in professional activities related to geriatric medicine. Reflecting on career decisions, 56% would again complete geriatric medicine fellowship, 21% would not, and 23% were unsure. 54% considered recertifying in geriatric medicine. 49% reported flexible MOC assessment options would increase likelihood of maintaining certification. CONCLUSIONS: The value proposition of geriatric medicine certification needs strengthening. Geriatric medicine leaders must develop strategies and tactics to reduce attrition of geriatricians by enhancing the value of geriatric medicine expertise to key stakeholders.

Geriatricians, general internists, and potentially inappropriate medications for a national sample of older adults.

BACKGROUND: Older adults are often prescribed medications that are potentially dangerous and geriatricians have specialized training in treating polypharmacy that may benefit these patients. To examine this, we compared potentially inappropriate medication (PIM) prescribing rates between geriatricians and similar general internists in the United States. METHODS: Using national cross-sectional data from 2013 to 2019, we compared annual PIM prescribing rates between 2815 outpatient geriatricians certified by the American Board of Internal Medicine in 1994-2018 and general internists matched 1:1 on IM certification exam score and year, residency exam pass rate, gender, and US birth and/or US medical school. PIM prescribing was based on the Healthcare Effectiveness Data and Information Set (HEDIS) PIM physician annual prescribing measures which consider medications flagged as potentially inappropriate in the American Geriatric Society Beers Criteria® guideline. We also examined prescribing of appropriate alternative medications. Prescribing rates were calculated as the percentage a physician's patients with Medicare fee-for-service part D enrollment seen in the outpatient setting in a given year (mean: 150 patients per physician) with a PIM prescription they prescribed. RESULTS: Across 30,677 physician-year observations, geriatricians were 16.7% less likely (95% confidence interval (CI): -19.8 to -13.7, p < 0.001) to prescribe a PIM (7.2% versus 8.7% of patients respectively) and 2.7% more likely (95% CI: 0.8 to 4.5, p = 0.004) to prescribe an appropriate alternative medication (52.0% versus 50.7% of patients respectively). Lower PIM prescribing was observed for most medication sub-types including central nervous system, anticholinergic, pain, and endocrine medications. In sensitivity analyses, differences in prescribing were similar when comparing recently trained physicians with more experienced physicians. CONCLUSION: Findings suggest geriatricians in the United States prescribe PIMs at lower rates than general internists. This highlights the value geriatricians provide as well as opportunities to embed key principles of geriatric care into internal medicine training and health care delivery systems.

Variation in Home Healthcare Use by Dementia Status Among a National Cohort of Older Adults.

BACKGROUND: Medicare-funded home healthcare (HHC) delivers skilled nursing, therapy, and related services through visits to the patient's home. Nearly one-third (31%) of HHC patients have diagnosed dementia, but little is currently known regarding how HHC utilization and care delivery differ for persons living with dementia (PLwD). METHODS: We drew on linked 2012-2018 Health and Retirement Study and Medicare claims for a national cohort of 1 940 community-living older adults. We described differences in HHC admission, length of stay, and referral source by patient dementia status and used weighted, multivariable logistic and negative binomial models to estimate the relationship between dementia and HHC visit type and intensity while adjusting for sociodemographic characteristics, health and functional status, and geographic/community factors. RESULTS: PLwD had twice the odds of using HHC during a 2-year observation period, compared to those without dementia (odds ratio [OR]: 2.03; p < .001). They were more likely to be referred to HHC without a preceding hospitalization (49.4% vs 32.1%; p < .001) and incurred a greater number of HHC episodes (1.4 vs 1.0; p < .001) and a longer median HHC length of stay (55.8 days vs 40.0 days; p < .001). Among post-acute HHC patients, PLwD had twice the odds of receiving social work services (unadjusted odds ratio [aOR]: 2.15; p = .008) and 3 times the odds of receiving speech-language pathology services (aOR: 2.92; p = .002). CONCLUSIONS: Findings highlight HHC's importance as a care setting for community-living PLwD and indicate the need to identify care delivery patterns associated with positive outcomes for PLwD and design tailored HHC clinical pathways for this patient subpopulation.

Patterns of Morbidity Across the Lifespan: A Population Segmentation Framework for Classifying Health Care Needs for All Ages.

BACKGROUND: Classification systems to segment such patients into subgroups for purposes of care management and population analytics should balance administrative simplicity with clinical meaning and measurement precision. OBJECTIVE: To describe and empirically apply a new clinically relevant population segmentation framework applicable to all payers and all ages across the lifespan. RESEARCH DESIGN AND SUBJECTS: Cross-sectional analyses using insurance claims database for 3.31 Million commercially insured and 1.05 Million Medicaid enrollees under 65 years old; and 5.27 Million Medicare fee-for-service beneficiaries aged 65 and older. MEASURES: The "Patient Need Groups" (PNGs) framework, we developed, classifies each person within the entire 0-100+ aged population into one of 11 mutually exclusive need-based categories. For each PNG segment, we documented a range of clinical and resource endpoints, including health care resource use, avoidable emergency department visits, hospitalizations, behavioral health conditions, and social need factors. RESULTS: The PNG categories included: (1) nonuser, (2) low-need child, (3) low-need adult, (4) low-complexity multimorbidity, (5) medium-complexity multimorbidity, (6) low-complexity pregnancy, (7) high-complexity pregnancy, (8) dominant psychiatric/behavioral condition, (9) dominant major chronic condition, (10) high-complexity multimorbidity, and (11) frailty. Each PNG evidenced a characteristic age-related trajectory across the full lifespan. In addition to offering clinically cogent groupings, large percentages (29%-62%) of patients in two pregnancy and high-complexity multimorbidity and frailty PNGs were in a high-risk subgroup (upper 10%) of potential future health care utilization. CONCLUSIONS: The PNG population segmentation approach represents a comprehensive measurement framework that captures and categorizes available electronic health care data to characterize individuals of all ages based on their needs.

Home-Based Medical Care Use In Medicare Advantage And Traditional Medicare In 2018.

The use of home-based medical care differed in Medicare Advantage and traditional Medicare in 2018. Having exactly one such visit was thirty-one times as likely for Medicare Advantage beneficiaries (18.6 percent) as for traditional Medicare beneficiaries (0.6 percent), likely reflecting incentives in the Medicare Advantage program to code all accurate diagnoses. Multiple home-based medical care visits were less likely in Medicare Advantage than in traditional Medicare (1.6 percent versus 2.1 percent of beneficiaries, respectively).

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.

Development and Validation of the Hospital-to-Home-Health Transition Quality (H3TQ) Index: A Novel Measure to Engage Patients and Home Health Providers in Evaluating Hospital-to-Home Care Transition Quality.

BACKGROUND: Patients requiring skilled home health care (HH) after hospitalization are at high risk of adverse events. Human factors engineering (HFE) approaches can be useful for measure development to optimize hospital-to-home transitions. OBJECTIVE: To describe the development, initial psychometric validation, and feasibility of the Hospital-to-Home-Health-Transition Quality (H3TQ) Index to identify patient safety risks. METHODS: Development: A multisite, mixed-methods study at 5 HH agencies in rural and urban sites across the United States. Testing: Prospective H3TQ implementation on older adults' hospital-to-HH transitions. Populations Studied: Older adults and caregivers receiving HH services after hospital discharge, and their HH providers (nurses and rehabilitation therapists). RESULTS: The H3TQ is a 12-item count of hospital-to-HH transitions best practices for safety that we developed through more than 180 hours of observations and more than 80 hours of interviews. The H3TQ demonstrated feasibility of use, stability, construct validity, and concurrent validity when tested on 75 transitions. The vast majority (70%) of hospital-to-HH transitions had at least one safety issue, and HH providers identified more patient safety threats than did patients/caregivers. The most frequently identified issues were unsafe home environments (32%), medication issues (29%), incomplete information (27%), and patients' lack of general understanding of care plans (27%). CONCLUSIONS: The H3TQ is a novel measure to assess the quality of hospital-to-HH transitions and proactively identify transitions issues. Patients, caregivers, and HH providers offered valuable perspectives and should be included in safety reporting. Study findings can guide the design of interventions to optimize quality during the high-risk hospital-to-HH transition.

Use of Home-Based Clinical Care and Long-Term Services and Supports Among Homebound Older Adults.

OBJECTIVES: Describe use of home-based clinical care and home-based long-term services and supports (LTSS) using a nationally representative sample of homebound older Medicare beneficiaries. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Homebound, community-dwelling fee-for-service Medicare beneficiaries participating in the 2015 National Health and Aging Trends Study (n = 974). METHODS: Use of home-based clinical care [ie, home-based medical care, skilled home health services, other home-based care (eg, podiatry)] was identified using Medicare claims. Use of home-based LTSS (ie, assistive devices, home modification, paid care, ≥40 hours/wk of family caregiving, transportation assistance, senior housing, home-delivered meals) was identified via self or proxy report. Latent class analysis was used to characterize patterns of use of home-based clinical care and LTSS. RESULTS: Approximately 30% of homebound participants received any home-based clinical care and about 80% received any home-based LTSS. Latent class analysis identified 3 distinct patterns of service use: class 1, High Clinical with LTSS (8.9%); class 2, Home Health Only with LTSS (44.5%); and class 3, Low Care and Services (46.6% homebound). Class 1 received extensive home-based clinical care, but their use of LTSS did not meaningfully differ from class 2. Class 3 received little home-based care of any kind. CONCLUSIONS AND IMPLICATIONS: Although home-based clinical care and LTSS utilization was common among the homebound, no single group received high levels of all care types. Many who likely need and could benefit from such services do not receive home-based support. Additional work focused on better understanding potential barriers to accessing these services and integrating home-based clinical care services with LTSS is needed.

The role of restrictive scope-of-practice regulations on the delivery of nurse practitioner-delivered home-based primary care.

BACKGROUND: Nurse practitioners (NPs) are the largest group of providers delivering home-based primary care (HBPC) in the U.S. We examined the association of scope-of-practice regulations and NP-HBPC rates. METHODS: Using the Centers for Medicare and Medicaid Services Provider Utilization and Payment Data Public Use File for 2019, we conducted a state-level analysis to examine the impact of scope-of-practice regulations on the utilization of NP-HBPC. Healthcare Common Procedure Coding System codes were used to identify the HBPC visits in private residences (99341-99,345, 99,347-99,350) and domiciliary settings (99324-99,328, 99,334-99,337). We used linear regression to compare NP-HBPC utilization rates between states of either restricted or reduced scope-of-practice laws to states with full scope-of-practice, adjusting for a number of NP-HBPC providers, state ranking of total assisted living, the proportion of fee-for-service (FFS) Medicare beneficiaries and neighborhood-level socio-economic status and race and ethnicity. RESULTS: Nearly half of NPs providing HBPC (46%; n = 7151) were in states with a restricted scope of practice regulations. Compared to states with full scope-of-practice, states with restricted or reduced scope-of-practice had higher adjusted rates of NP-HBPC per 1000 FFS Medicare beneficiaries. The average level of the utilization rate of NP-HBPC was 89.9, 63, and 49.1 visits, per 1000 FFS Medicare beneficiaries in states with restricted, reduced, and full- scope-of-practice laws, respectively. The rate of NP-HBPC visits was higher in states with restricted (Beta coefficient = 0.92; 95%CI 0.13-1.72; p = 0.023) and reduced scope-of-practice laws (Beta coefficient = 0.91; 95%CI 0.03-1.79; p = 0.043) compared to states with full scope-of-practice laws. CONCLUSION: Restricted state NP scope-of-practice regulations were associated with higher rates of FFS Medicare NP-HBPC care delivery compared with full or reduced scope-of-practice. Understanding underlying mechanisms of how scope-of-practice affects NP-HBPC delivery could help to develop scope-of-practice regulations that improve access to HBPC for the underserved homebound population.

Senior Services in US Hospitals and Readmission Risk or Mortality Among Medicare Beneficiaries Since the Affordable Care Act.

Background: The Senior Care Services Scale (SCSS) describes hospital provision of older adult services before the passage of the Affordable Care Act. Objectives: Since act passage, (1) update SCSS service groups; and (2) investigate hospital SCSS scores' relationship to readmission or mortality among Medicare beneficiaries. Methods: Retrospective cohort analysis of older adults ≥65 years (n = 1,416,669), admitted to 2570 US acute-care hospitals from 2014 to 2015. Outcomes: Hospital readmission, or death, within 30 and 90 days of discharge. Results: The updated SCSS had three service groups: Inpatient Specialty Care, Post-Acute Community Care, and Home Care and Hospice. Older adults admitted to high Inpatient-Specialty-Care-scoring hospitals had lower risk of death within 30 days (RR .94, 95% CI .91-.98), and 90 days (RR .94, 95% CI .91-.97). There was no significant association between Home-Care-and-Hospice and Post-Acute-Community-Care scores and study outcomes. Conclusion: Greater provision of hospital-level senior services may be associated with mortality reduction among Medicare beneficiaries.

The heterogeneity of the homebound: A latent class analysis of a national sample of homebound older adults.

BACKGROUND: Homebound status is a final common pathway for people with a variety of diseases and conditions. There are 7 million homebound older adults in the United States. Despite concerns regarding their high healthcare costs and utilization and limited access to care, the unique subsets within the homebound population are understudied. Better understanding of distinct homebound groups may enable more targeted and tailored approaches to care delivery. Therefore, in a nationally representative sample of homebound older adults we used latent class analysis (LCA) to examine distinct homebound subgroups based on clinical and sociodemographic characteristics. MATERIALS AND METHODS: Using data from the National Health and Aging Trends Study (NHATS) 2011-2019, we identified 901 newly homebound persons (defined as never/rarely leaving home or leaving home only with assistance and/or difficulty). Sociodemographic, caregiving context, health and function, and geographic covariates were derived from NHATS via self-report. LCA was used to identify the existence of distinct subgroups within the homebound population. Indices of model fit were compared for models testing 1-5 latent classes. Association between latent class membership and 1 year mortality was examined using a logistic regression. RESULTS: We identified four classes of homebound individuals differentiated by their health, function, sociodemographic characteristics, and caregiving context: (i) Resource constrained (n = 264); (ii) Multimorbid/high symptom burden (n = 216); (iii) Dementia/functionally impaired (n = 307); (iv) Older/assisted living (n = 114). One year mortality was highest among the older/assisted living subgroup (32.4%) and lowest among the resource constrained (8.2%). CONCLUSIONS: This study identifies subgroups of homebound older adults characterized by distinct sociodemographic and clinical characteristics. These findings will support policymakers, payers, and providers in targeting and tailoring care to the needs of this growing population.
