Medicaid home- and community-based services and discharge from skilled nursing facilities

The role of Medicaid home- and community-based services in use of Medicare post-acute care

OBJECTIVE

Medicaid-funded long-term services and supports are increasingly provided through home- and community-based services (HCBS) to promote continued community living. While an emerging body of evidence examines the direct benefits and costs of HCBS, there may also be unexplored synergies with Medicare-funded post-acute care (PAC). This study aimed to provide empirical evidence on how the use of Medicaid HCBS influences Medicare PAC utilization among the dually enrolled.

DATA SOURCES

National Medicare claims, Medicaid claims, nursing home assessment data, and home health assessment data from 2016 to 2018.

STUDY DESIGN

We estimated the relationship between prior Medicaid HCBS use and PAC (skilled nursing facilities [SNF] or home health) utilization in a national sample of duals with qualifying index hospitalizations. We used inverse probability weights to create balanced samples on observed characteristics and estimated multivariable regression with hospital fixed effects and extensive controls. We also conducted stratified analyses for key subgroups.

DATA EXTRACTION METHODS

The primary sample included 887,598 hospital discharges from community-dwelling duals who had an eligible index hospitalization between April 1, 2016, and September 30, 2018.

PRINCIPAL FINDINGS

We found HCBS use was associated with a 9 percentage-point increase in the use of home health relative to SNF, conditional on using PAC, and a meaningful reduction in length of stay for those using SNF. In addition, in our primary sample, we found HCBS use to be associated with an overall increase in PAC use, given that the absolute increase in home health use was larger than the absolute decrease in SNF use. In other words, the use of Medicaid-funded HCBS was associated with a shift in Medicare-funded PAC use toward home-based settings.

CONCLUSION

Our findings indicate potential synergies between Medicaid-funded HCBS and increased use of home-based PAC, suggesting policymakers should cautiously consider these dynamics in HCBS expansion efforts.

Outcomes After Community Discharge From Skilled Nursing Facilities: The Role of Medicaid Home and Community-Based Services

This study investigated the association between Medicaid Home and Community-Based Services (HCBS) generosity and post-discharge outcomes among dual-eligible beneficiaries discharged from skilled nursing facilities (SNFs). We linked multiple national datasets for duals discharged from SNFs between 2010 and 2013. Accounting for SNF fixed effects, we estimated the effect of HCBS generosity, measured by its breadth and intensity, on the likelihood of remaining in the community, risks of death, nursing home (NH) admission, and hospitalizations within 30 and 180 days after SNF discharge. We found that higher HCBS generosity was associated with an increased likelihood of remaining in the community. HCBS breadth and intensity were both significantly associated with reduced risks of NH admission, while higher HCBS intensity was related to a reduced risk of acute hospitalizations within 30 days after discharge. Our findings suggest that more generous HCBS programs may facilitate smoother transitions and sustainable community living following SNF discharge.

The relationship between Medicaid policy and realized access to home- and community-based services

Medicaid funding for home- and community-based services (HCBS) has increased substantially in recent decades. Prior research has investigated the effects of this expansion on outcomes for individuals as well as costs to Medicaid, often using state policy as a proxy for access to HCBS or implicitly assuming that more generous policies affect outcomes through access, an assumption that may not hold. In this study, using survey data linked to Medicaid claims, we assess the extent to which common measures of state Medicaid HCBS generosity correspond to increased individual use of HCBS among older adults with potential needs. We find several measures to have strong predictive power, but only with relatively large changes in policy generosity. Our findings imply that increased funding of HCBS is not sufficient to ensure access to services and that researchers should be careful when using state policy generosity as a proxy for access.

Unmet Needs for Help With Mobility Limitations Among Older Adults Aging in Place: The Role of Rurality

OBJECTIVES

This study identifies differences in unmet mobility needs among older adults living in rural versus urban areas.

METHODS

We used data from Round 9 of the National Health and Aging Trends Study (NHATS), limiting our analyses to respondents who had not moved since baseline (average housing tenure of 27 years; n = 3343). We conducted bivariate and multivariate analyses to detect rural/urban differences in unmet mobility needs, adjusting for socio-demographics, health status, and housing characteristics.

RESULTS

Rural residence was associated with higher odds of any unmet mobility needs for older adults aging in place (adjusted odds ratio: 1.64, 95% confidence interval: 1.10-2.44, p < .05). The relationship between rurality and unmet needs for help with mobility limitations remained significant in fully adjusted models.

DISCUSSION

Rural older adults aging in place have greater unmet needs for help with mobility limitations. This study highlights several important gaps in supporting rural older adults aging in place.

Trends In Medicaid Home And Community-Based Services Waivers For Older Adults

During the past several decades, state Medicaid programs have expanded the use of home and community-based services, particularly through Section 1915(c) waivers and Section 1115 demonstration waivers. We document trends from the period 1997-2020 in waivers targeting older adults, focusing on services offered. Nearly every service category saw an increase in coverage and spending, especially support for self-direction and community transition.

Examining variation in state spending on medicaid long-term services and supports for older adults

State Medicaid programs are the largest source of funding for long-term services and supports (LTSS). We characterized states across quartiles of mean LTSS spending for individuals ≥65 and used the Health and Retirement Study to examine the demographic, functional, and caregiving characteristics across these quartiles. Individuals in states with lower Medicaid spending on LTSS reported more family and friend caregiving hours and were more likely to be from racial and ethnic minority groups. Continued work is needed to improve Medicaid LTSS policy to better support vulnerable populations, particularly in lower quartile states.

Nursing home admissions for persons with dementia: Role of home- and community-based services

OBJECTIVE

To examine the relationship between Medicaid home- and community-based services (HCBS) generosity and the likelihood of nursing home (NH) admission for dually enrolled older adults with Alzheimer's disease and related dementias (ADRD) and their level of physical and cognitive impairment at NH admission.

DATA SOURCES

National Medicare data, Medicaid Analytic eXtract, and MDS 3.0 for CY2010-2013 were linked.

STUDY DESIGN

Eligible Medicare-Medicaid dual beneficiaries with ADRD were identified and followed for up to a year. We constructed two measures of HCBS generosity, breadth and intensity, at the county level for older duals with ADRD. Three binary outcomes were defined as follows: any NH placement during the follow-up year for all individuals in the sample, high (vs. not high) physical impairment, and high (vs. not high) cognitive impairment at the time of NH admission for those who were admitted to an NH. Logistic regressions with state-fixed effects and county random effects were estimated for these outcomes, respectively, accounting for individual- and county-level covariates.

DATA EXTRACTION METHODS

The study sample included 365,310 community-dwelling older dual beneficiaries with ADRD who were enrolled in fee-for-service Medicare and Medicaid between October 1, 2010, and December 31, 2012.

PRINCIPAL FINDINGS

Considerable variations of breadth and intensity in county-level HCBS were observed. We found that a 10-percentage-point increase in HCBS breadth was associated with a 1.4 (p < 0.01)-percentage-point reduction in the likelihood of NH admission. Among individuals with NH admission, greater HCBS breadth was associated with a higher level of physical impairment, and greater HCBS intensity was associated with a higher level of physical and cognitive impairment at NH admission.

CONCLUSIONS

Among community-dwelling duals with ADRD, Medicaid HCBS generosity was associated with a lower likelihood of NH admission and greater functional impairment at NH admission.
