The causal effects of home care use on institutional long-term care utilization and expenditures

Evaluating the health outcomes of aging in place: the role of medicaid aging waiver program on U.S. older adults

The Medicaid Aging Waiver program (MAW) subsidizes the cost of long-term care (LTC) at home or in communities to satisfy older people's increasing desire to age in place. The MAW program might be health improving for older people by allowing them to age at home. However, less quality and quantity of home-based care comparing to nursing home care could offset some of the potential benefits. I use policy expenditure across states over time linked with detailed health information from the Health and Retirement Study (HRS) to identify the associated effects of MAWs on health outcomes of older adults who are at risk of needing LTC and who are resources constrained to be potentially eligible for Medicaid. Overall, the findings suggest that the MAW program is beneficial to health: a $1,000 increase in MAW spending for each older person results is associated with a 1.4 percent improvement in self-reported health status, a 1.5 percent reduction in functional mobility limitations, a 1.6 percent decrease in Instrumental Activities of Daily Living (IADL) limitations, and a 1.7 percent improvement in negative psychological feelings. For older people who are most likely not eligible for MAWs, such as those who are wealthy or in good health and do not require LTC, these health-improving effects have not been observed.

Preimplementation Evaluation of a Self-Directed Care Program in a Veterans Health Administration Regional Network: Protocol for a Mixed Methods Study

BACKGROUND

The Veteran-Directed Care (VDC) program serves to assist veterans at risk of long-term institutional care to remain at home by providing funding to hire veteran-selected caregivers. VDC is operated through partnerships between Department of Veterans Affairs (VA) Medical Centers (VAMCs) and third-party Aging and Disability Network Agency providers.

OBJECTIVE

We aim to identify facilitators, barriers, and adaptations in VDC implementation across 7 VAMCs in 1 region: Veterans Integrated Service Network (VISN) 8, which covers Florida, South Georgia, Puerto Rico, and the US Virgin Islands. We also attempted to understand leadership and stakeholder perspectives on VDC programs' reach and implementation and identify veterans served by VISN 8's VDC programs and describe their home- and community-based service use. Finally, we want to compare veterans served by VDC programs in VISN 8 to the veterans served in VDC programs across the VA. This information is intended to be used to identify strategies and propose recommendations to guide VDC program expansion in VISN 8.

METHODS

The mixed methods study design encompasses electronically delivered surveys, semistructured interviews, and administrative data. It is guided by the Consolidated Framework for Implementation Research (CFIR version 2.0). Participants included the staff of VAMCs and partnering aging and disability network agencies across VISN 8, leadership at these VAMCs and VISN 8, veterans enrolled in VDC, and veterans who declined VDC enrollment and their caregivers. We interviewed selected VAMC site leaders in social work, Geriatrics and Extended Care, and the Caregiver Support Program. Each interviewee will be asked to complete a preinterview survey that includes information about their personal characteristics, experiences with the VDC program, and perceptions of program aspects according to the CFIR (version 2.0) framework. Participants will complete a semistructured interview that covers constructs relevant to the respondent and facilitators, barriers, and adaptations in VDC implementation at their site.

RESULTS

We will calculate descriptive statistics including means, SDs, and percentages for survey responses. Facilitators, barriers, number of patients enrolled, and staffing will also be presented. Interviews will be analyzed using rapid qualitative techniques guided by CFIR domains and constructs. Findings from VISN 8 will be collated to identify strategies for VDC expansion. We will use administrative data to describe veterans served by the programs in VISN 8.

CONCLUSIONS

The VA has prioritized VDC rollout nationwide and this study will inform these expansion efforts. The findings from this study will provide information about the experiences of the staff, leadership, veterans, and caregivers in the VDC program and identify program facilitators and barriers. These results may be used to improve program delivery, facilitate growth within VISN 8, and inform new program establishment at other sites nationwide as the VDC program expands.

A panel vector autoregression analysis for the dynamics of medical and long-term care expenditures

Although medical and long-term care expenditures for older adults are closely related, providing rigorous statistical analysis for their dynamic relationship is challenging. In this research, we propose a novel approach using the panel vector autoregression model to reveal the realized patterns of the interdependence. As an empirical application, we analyze monthly panel data on individuals in a city of Japan, where social insurance covers many formal services for long-term care. Our estimation results indicate the existence of intertemporal transition from expensive acute medical care to reasonable at-home medical care, then to at-home long-term care. Under this context, the enhancement of formal long-term care sector in Japan might have played an important role in the suppression of the total care cost in spite for its rapid aging over the past 2 decades. Additionally, we find that daycare plays multiple roles in Japanese long-term care, such as respite and rehabilitation, but there is no considerable transition from outpatient rehabilitation to daycare in the long-term care sector.

Home and Community-Based Service Use Varies by Health Care Team and Comorbidity Level of Veterans with Dementia

Home and community-based services (HCBSs) such as home care and adult day centers are vital to supporting adults with dementia in community settings. We investigated whether HCBS use (use of both home care and adult day, use of one service, and use of neither service) varied between adults receiving care from three types of health-care teams with case management from social workers and nurses, and by comorbidity level, using 2019 data of 143,281 patients with dementia in the Veterans Health Administration. We compared HCBS use by patients' type of case-managed team (Home-Based Primary Care, geriatrics-based primary care, and dementia-focused specialty care) to patients in none of these teams, stratified by patients' non-dementia comorbidities (<4 or ≥4). Each type of health-care team was associated with both home care and adult day services, at each level of comorbidity. Home-Based Primary Care was most consistently associated with other forms of HCBS use, followed by Dementia Clinics and geriatrics-based primary care, for patients with ≥4 non-dementia comorbidities. Our findings suggest that case management in primary and specialty care settings is a contributor to the use of critical community supports by patients with the most complex needs.

Investigating community-based care service factors delaying residential care home admission of community dwelling older adults and cost consequence

OBJECTIVES

To examine factors contributing to delaying care home admission; and compare the rates of care home admission and cost consequence between two government subsidised programmes, Veterans' Affairs Community Nursing (VCN) and Home Care Package (HCP).

METHODS

Our national, population-based retrospective cohort study and cost analysis used existing, de-identified veterans' claims databases (2010-19) and the Registry of Senior Australians Historical Cohort (2010-17), plus aggregate programme expenditure data. This involved 21,636 VCN clients (20,980 aged 65-100 years), and an age- and sex-matched HCP cohort (N = 20,980).

RESULTS

Service factors associated with lower risk of care home admission in the VCN cohort were periodic (versus continuous) service delivery (HR 0.27 [95%CI, 0.24-0.31] for ≤18 months; HR 0.89 [95%CI, 0.84-0.95] for >18 months), and majority care delivered by registered nurses (versus personal care workers) (HR 0.86 [95%CI, 0.75-0.99] for ≤18 months; HR 0.91 [95%CI, 0.85-0.98] for >18 months). In the matched cohorts, the time to care home admission for VCN clients (median 28 months, IQR 14-42) was higher than for HCP clients (14, IQR 6-27). Within 5 years of service access, 57.6% (95%CI, 56.9-58.4) of HCP clients and 26.6% (95%CI, 26.0-27.2) of VCN clients had care home admission. The estimated cost saving for VCN recipients compared to HCP recipients over 5 years for relevant government providers was over A$1 billion.

CONCLUSIONS

Compared to an HCP model, individuals receiving VCN services remained at home longer, with potentially significant cost savings. This new understanding suggests timely opportunity for many countries' efforts to enhance community-based care services.

Long-term care service mix in the Veterans Health Administration after home care expansion

OBJECTIVE

To determine whether the Veterans Health Administration's (VHA) efforts to expand access to home- and community-based services (HCBS) after the 2001 Millennium Act significantly changed Veterans' utilization of institutional, paid home, and unpaid home care relative to a non-VHA user Medicare population that was not exposed to HCBS expansion efforts.

DATA SOURCES

We used linkages between the Health and Retirement Study and VHA administrative data from 1998 until 2012.

STUDY DESIGN

We conducted a retrospective-matched cohort study using coarsened exact matching to ensure balance on observable characteristics for VHA users (n = 943) and nonusers (n = 6106). We used a difference-in-differences approach with a person fixed-effects estimator.

DATA COLLECTION/EXTRACTION METHODS

Individuals were eligible for inclusion in the analysis if they were age 65 or older and indicated that they were covered by Medicare insurance in 1998. Individuals were excluded if they were covered by Medicaid insurance at baseline. Individuals were considered exposed to VHA HCBS expansion efforts if they were enrolled in the VHA and used VHA services.

PRINCIPAL FINDINGS

Theory predicts that an increase in the public allocation of HCBS will decrease the utilization of its substitutes (e.g., institutional care and unpaid caregiving). We found that after the Millennium Act was passed, there were no observed differences between VHA users and nonusers in the probability of using institutional long-term care (0.7% points, 95% CI: -0.009, 0.022) or in receiving paid help with activities of daily living (0.06% points, 95% CI: -0.011, 0.0125). VHA users received more hours of unpaid care post-Millennium Act (1.48, 95% CI: -0.232, 3.187), though this effect was not significant once we introduced controls for mental health.

CONCLUSIONS

Our findings indicate that mandating access to HCBS services does not necessarily imply that access to these services will follow suit.

Leveraging survey and claims data to identify high-need Medicare beneficiaries in the National Health and Aging Trends Study

BACKGROUND

Multiple algorithms have been developed to identify and characterize the high-need (HN) Medicare population. However, they vary in components and yield different populations, and were developed for varying purposes. We compared the performance of existing survey and claims-based definitions in identifying HN beneficiaries and predicting poor outcomes among a community-dwelling population.

METHODS

A retrospective cohort study using Round 5 (2015) of the National Health and Aging Trends Study (NHATS) linked with Medicare claims. We applied HN definitions from previous studies to our cohort of community-dwelling, fee-for-service beneficiaries (n = 4201) using sampling weights to obtain nationally representative estimates. The Bélanger et al. (2019) definition defines HN as individuals with complex conditions, multi-morbidity, acute and post-acute healthcare utilization, dependency in activities of daily living, and frailty. The Hayes et al. (2016) definition defines HN as individuals with 3+ chronic conditions and a functional limitation. We applied each definition to survey and claims data. Outcomes were hospitalization or mortality in the subsequent year.

RESULTS

The proportion of NHATS respondents classified as HN varied greatly across definitions, ranging from 3.1% using the claims-based Hayes definition to 32.9% using the survey-based Bélanger definition. HN respondents had significantly higher mortality and hospitalization rates in 2016. Although all definitions had good specificity, none were able to predict outcomes in the following year with good accuracy.

CONCLUSIONS

While mortality and hospitalization rates were significantly higher among respondents classified as HN, existing claims and survey-based HN definitions were not able to accurately predict future outcomes in a community-dwelling, nationally representative sample measured by the area under the curve.

State Medicaid Home and Community-Based Services Policies and Health Expenditures by Payer

This study examines the relationship between two state Medicaid home and community-based services (HCBS) policies - number of beneficiaries (Participation) and use per beneficiary (Intensity) - and individual health expenditures. Data include the 2008-2013 Medicare Current Beneficiary Survey and state-level Medicaid HCBS indicators. Two-part generalized linear models are estimated for health expenditures by payer and dual-eligibility status. The likelihood and level of Medicare expenditures are significantly lower in states in the top quartile of Participation and Intensity. Findings suggest that state Medicaid HCBS policies may impact health expenditures, with potential spillover effects on Medicare spending.

Substitute services: a barrier to controlling long-term care expenditures

In many developed countries, long-term care expenditures are a major source of concern, which has urged policy makers to reduce costs. However, long-term care financing is highly fragmented in most countries and hence reducing total costs might be complicated by spillover effects: spending reductions on one type of care may be offset elsewhere in the system if consumers shop around for substitutes. These spillovers may be substantial, as we show using a reform in the budget for municipalities for the most common type of publicly financed home care in the Netherlands, domestic help. This reform generated an exogenous change in the grant for domestic help that does not depend on changes in its demand. We show that the change in budget affected consumption of this care type, but that this effect was mitigated by offsetting changes in the consumption of three other types of home care that are financed through another public scheme and are organized through regional single payers. We find that a 10 euro increase in the grant for domestic help increased use of domestic help and nursing by 0.13 and 0.03 h per capita (4.4 and 5.2% of use in 2007), whereas it decreases use of individual assistance and personal care by 0.03 and 0.05 h per capita (4.1 and 2.9% of use in 2010 and 2007, respectively). As a result, the total spending effect is closer to zero than the effect on domestic help suggests. This finding means that the fragmentation of long-term care financing limits the ability to control expenditure growth.

Better off at home? Effects of nursing home eligibility on costs, hospitalizations and survival

Encouraging and helping elderly to postpone a nursing home admission appears to be a win-win that keeps long-term care spending in check and is in line with the target population's preferences, but there is little evidence about its effects. We study the causal impact of nursing home admission eligibility using Dutch administrative data and exploiting variation between randomly assigned assessors in their tendency to grant eligibility for a nursing home admission. We find a drop in medical care use when eligibility is granted, especially in hospital admissions, while total healthcare spending is unaffected. This suggests that postponing an admission may not always be a win-win after all.

The effect of functional status impairment on nursing home admission risk among patients with advanced Parkinson's disease

Aims: To estimate the relationship between functional status (FS) impairment and nursing home admission (NHA) risk in Parkinson's disease (PD) patients, and quantify the effect of advanced PD (APD) treatment on NHA risk relative to standard of care (SoC).Materials and methods: PD patients were identified in the Medicare Current Beneficiary Survey (MCBS) (1992-2010). A working definition based on the literature and clinical expert input determined APD status. A logit model estimated the relationship between FS impairment and NHA risk. The effect of levodopa-carbidopa intestinal gel (LCIG) on NHA risk relative to SoC was simulated using clinical trial data (control: optimized oral levodopa-carbidopa IR, ClinicalTrials.gov NCT00660387 and NCT0357994).Results: Non-advanced PD and APD significantly increased NHA risk when controlling for demographics (p < 0.01). APD status was no longer significant after controlling for FS limitations, implying that FS limitations explain the increased NHA risk in APD patients. Reduced impairment in FS in patients with APD treated with LCIG reduced risk of NHA by 13.5% relative to SoC.Limitations: This study applies clinical trial results to real-world data. LCIG treatment might have a different effect on NHA risk for the nationally representative population than the effect measured in the trial. Both data sources employ different instruments to measure FS, instrument wording and study follow-up differed, which might bias our estimates. Finally, there lacks consensus on a definition of APD. The prevalence of APD in this study is high, perhaps due to the specific definition used.Conclusions: Patients with APD experience a higher risk in NHA than those with non-advanced disease. This increased risk in NHA in patients with APD is explained by greater limitations in FS. The relative reduction in risk of NHA for the APD population treated with LCIG is quantitatively similar to doubling Medicaid home care services.

Do Family Caregivers Offset Healthcare Costs for Older Adults? A Mapping Review on the Costs of Care for Older Adults With Versus Without Caregivers

BACKGROUND AND OBJECTIVES

Older adults face significant long-term care and health care costs. But some of these costs can potentially be offset through family caregivers who may serve as substitutes for formal care or directly improve the care recipient's health and reduce health care utilization and expenditures. This article reviews the current literature to determine whether it is possible through existing work to compare the costs of care for individuals with versus without family caregivers and, if not, where the data, measurement, and other methodological challenges lie.

RESEARCH DESIGN AND METHODS

A mapping review of published works containing information on health care utilization and expenditures and caregiving was conducted. A narrative approach was used to review and identify methodological challenges in the literature.

RESULTS

Our review identified 47 articles that met our criteria and had information on caregiving and health care costs or utilization. Although findings were mixed, for the most part, having a family caregiver was associated with reduced health care utilization and a decreased risk of institutionalization however, the precise difference in health care expenditures for individuals with caregivers compared to those without was rarely examined, and findings were inconsistent across articles reviewed.

DISCUSSION AND IMPLICATIONS

The number of family caregivers providing care to loved ones is expected to grow with the aging of the Baby Boomers. Various programs and policies have been proposed to support these caregivers, but they could be costly. These costs can potentially be offset if family caregivers reduce health care spending. More research is needed, however, to quantify the savings stemming from family caregiving.

What is the marginal benefit of payment-induced family care? Impact on Medicaid spending and health of care recipients

Research on home-based long-term care has centered almost solely on the costs; there has been very little, if any, attention paid to the relative benefits. This study exploits the randomization built into the Cash and Counseling Demonstration and Evaluation program that directly impacted the likelihood of having family involved in home care delivery. Randomization in the trial is used as an instrumental variable for family involvement in care, resulting in a causal estimate of the effect of changing the combination of home health-care providers on health-care utilization and health outcomes of the beneficiary. We find that some family involvement in home-based care significantly decreases health-care utilization: lower likelihood of emergency room use, Medicaid-financed inpatient days, any Medicaid hospital expenditures, and fewer months with Medicaid-paid inpatient use. We find that individuals who have some family involved in home-based care are less likely to have several adverse health outcomes within the first 9 months of the trial, including lower prevalence of infections, bedsores, or shortness of breath, suggesting that the lower utilization may be due to better health outcomes.

Living arrangements and disability-free life expectancy in the United States

No studies have investigated the association between living arrangements and disability-free life expectancy in the United States, nor worldwide. This study aims to examine the differences in total and disability-free life expectancy among older Americans according to living arrangements. Data from the Health and Retirement Study (1998 to 2014) for non-Hispanic whites aged 50 and over (N = 21,612). Disability-free life expectancy by gender, living arrangement, and education are obtained from incidence-based multistate life tables. Overall, those who live only with their spouses/partners live 1-19 years longer with 3-25 more years without disability and 1-7 fewer years with disability than do those with other living arrangements. Among those with the same living arrangement, the higher educated live up to 6 years longer with up to 8 more years in a disability-free state and up to 2 fewer years in a disabled state. The study shows strong association between living arrangement and disability-free life expectancy by gender and education. Long-term care policy should take into account the length of life with/without disability by living arrangements and socioeconomic status and make use of the potential family resources.

The effect of workforce assignment on performance: Evidence from home health care

Effective workforce assignment has the potential for improving performance. Using novel home health data combining provider work logs, personnel data, and detailed patient records, we estimate the effect of provider handoffs-a marker of care discontinuity-on hospital readmissions, an important performance measure for healthcare systems. We use workflow interruption caused by attrition and providers' work inactivity as an instrument for nurse handoffs. We find handoffs to substantially increase hospital readmissions. Our estimates imply that a single handoff increases the likelihood of 30-day hospital readmission by 16 percent and one in four hospitalizations during home health care would be avoided if handoffs were eliminated. Moreover, handoffs are more detrimental for high-severity patients and expedite hospital readmission. The frequency and sequencing of handoffs also affect the likelihood of rehospitalization.

Comprehensive Support for Family Caregivers of Post-9/11 Veterans Increases Veteran Utilization of Long-term Services and Supports: A Propensity Score Analysis

Family caregivers are an important component of the long-term services and supports (LTSS) system. However, caregiving may have negative consequences for caregiver physical and emotional health. Connecting caregivers to formal short-term home- and community-based services (HCBS), through information resources and referrals, might alleviate family caregiver burden and delay nursing home entry for the patient. The aim of this study was to evaluate the early impact of the Program of Comprehensive Assistance for Family Caregivers (PCAFC) (established by P.L. 111-163 for family caregivers of seriously injured post-9/11 Veterans) on Veteran use of LTSS. A two-cohort pre-post design with a nonequivalent comparison group (treated n = 15 650; comparison n = 8339) was used to (1) examine the association between caregiver enrollment in PCAFC and any VA-purchased or VA-provided LTSS use among Veterans and (2) describe program-related trends in HCBS and institutional LTSS use. The comparison group was an inverse-propensity-score weighted sample of Veterans whose caregivers applied for, but were not accepted into, the program. From baseline through 24 months post application, use of any LTSS ranged from 13.1% to 17.8% for Veterans whose caregivers were enrolled in PCAFC versus from 3.8% to 5.3% for Veterans in the comparison group. Participation in PCAFC was associated with a statistically significant increased use of any LTSS from 1 to 24 months post application (over time odds ratios ranged from 2.71 [95% confidence interval: 2.31-3.17] to 4.86 [3.93-6.02]). Support for family caregivers may enhance utilization of LTSS for Veterans with physical, emotional, and/or cognitive conditions.

"We don't have the infrastructure to support them at home": How health system inadequacies impact on long-term care admissions of people with dementia

OBJECTIVES

The influence of healthcare system factors on long-term care admissions has received relatively little attention. We address this by examining how inadequacies in the healthcare system impact on long-term care admissions of people with dementia. This is done in the context of the Irish healthcare system.

METHODS

Thirty-eight qualitative in-depth interviews with healthcare professionals and family carers were conducted. Interviews focused on participants' perceptions of the main factors which influence admission to long-term care. Interviews were analysed thematically.

RESULTS

The findings suggest that long-term care admissions of people with dementia may be affected by inadequacies in the healthcare system in three ways. Firstly, participants regarded the economic crisis in Ireland to have exacerbated the under-resourcing of community care services. These services were also reported to be inequitable. Consequently, the effectiveness of community care was seen to be limited. Secondly, such limits in community care appear to increase acute hospital admissions. Finally, admission of people with dementia to acute hospitals was believed to accelerate the journey towards long-term care.

CONCLUSIONS

Inadequacies in the healthcare system are reported to have a substantial impact on the threshold for long-term care admissions. The findings indicate that we cannot fully understand the factors that predict long-term care admission of people with dementia without accounting for healthcare system factors on the continuation of homecare.

Pay less, consume more? The price elasticity of home care for the disabled elderly in France

Little is known about the price sensitivity of demand for home care of the disabled elderly. We partially fill this knowledge gap by using administrative data on the beneficiaries of the main French home care subsidy program in a department and exploiting interindividual variation in provider prices. We address the potential endogeneity of prices by taking advantage of the unequal spatial coverage of providers and instrumenting price by the number of municipalities served by a provider. We estimate a price elasticity of around -0.4 that is significantly different from both 0 and -1. This less than proportionate response of consumption to price has implications for the efficiency and redistributive impact of variation in the level of copayments in home care subsidy schemes.

Explaining declining rates of institutional LTC use in the Netherlands: a decomposition approach

The use of long-term care (LTC) is changing rapidly. In the Netherlands, rates of institutional LTC use are falling, whereas homecare use is growing. Are these changes attributable to declining disability rates, or has LTC use given disability changed? And have institutionalization rates fallen regardless of disability level, or has LTC use become better tailored to needs? We answer these questions by explaining trends in LTC use for the Dutch 65+ population in the period 2000-2008 using a nonlinear variant of the Oaxaca-Blinder decomposition. We find that changes in LTC use are not due to shifts in the disability distribution but can almost entirely be traced back to changes in the way the system treats disability. Elderly with mild disability are more likely to be treated at home than before, whereas severely disabled individuals continue to receive institutional LTC. As a result, LTC use has become better tailored to the needs for such care. This finding suggests that policies that promote LTC in the community rather than in institutions can effectively mitigate the consequences of population aging on LTC spending.
