Abstract
OBJECTIVES: To investigate the association of the utilization of Medicare-certified home health agency (CHHA) services with post-acute skilled nursing facility (SNF) discharge outcomes that included home time, rehospitalization, SNF readmission, and mortality. DESIGN: Retrospective cohort study. SETTING: New York State fee-for-service Medicare beneficiaries aged 65 years and older admitted to SNFs for post-acute care and discharged to the community in 2014. PARTICIPANTS: A total of 25,357 older adults. MEASUREMENTS: The outcomes included days spent alive in the community ("home time"), rehospitalization, SNF readmission, and mortality within 30- and 90-day post-SNF discharge periods. The primary independent variables were SNF five-star overall quality rating and receipt of CHHA services within 7 days of SNF discharge. Zero-inflated negative binomial regression and logistic regression models characterized the association of CHHA linkage with home time and other outcomes, respectively. RESULTS: Following SNF discharge, 17,657 (69.6%) patients received CHHA services. In analyses that adjusted for patient-, market-, and other SNF-level factors, older adults discharged from higher quality SNFs were more likely to receive CHHA services. In analyses that adjusted for patient- and market-level factors, receipt of post-SNF CHHA services was associated with 2.03 and 4.17 (P < .001) more days in the community over 30- and 90-day periods. Receiving CHHA services was also associated with decreased odds for rehospitalization (odds ratio [OR] = .68; P < .001; OR = .91; P = .008), SNF readmission (OR = .36; P < .001; OR = .62; P < .001), and death (OR = .34; P < .001; OR = .63; P < .001) over 30- and 90-day periods, respectively. CONCLUSION: Among older adults discharged from a post-acute SNF stay, those who received CHHA services had better discharge outcomes. They were less likely to experience admissions to institutional care settings and had a lower mortality risk. Future efforts that examine how the type and intensity of CHHA services affect outcomes would build on this work. J Am Geriatr Soc 68:1573-1578, 2020.
