Objectives: Home health care serves millions of Americans who are "Aging in Place," including the rapidly growing population of Medicare Advantage (MA) enrollees. This study systematically reviewed extant evidence illustrating home health care (HHC) services to MA enrollees.
Methods: A comprehensive literature search was conducted in 6 electronic databases to identify eligible studies, which resulted in 386 articles. Following 2 rounds of screening, 30 eligible articles were identified. Each study was also assessed independently for study quality using a validated quality assessment checklist.
Results: Of the 30 studies, nearly half (n=13) were recently published between January 1, 2017 - January 6, 2022. Among various issues related to HHC to MA enrollees examined, which were often compared with Traditional Medicare (TM) enrollees, the 2 most studied issues were HHC use rate (including access) and care dosage/intensity. Inconsistencies were common in findings across reviewed studies, with slight variations in the level of inconsistency by studied outcomes. Several critical issues, such as heterogeneity of MA plans, influence of MA-specific features, and program response to policy and quality improvement initiatives, were only examined by 1 or 2 studies. The depth and scope of scientific investigation were also limited by the scale and details available in MA data in addition to other methodological limits.
Conclusions: Wild variations and conflicting findings on HHC to MA beneficiaries exist across studies. More research with rigorous designs and robust MA encounter data is warranted to determine home health care for MA enrollees and the relevant outcomes.
