Outcomes of advanced care management in home-based long-term care: A retrospective population-based observational study

Background In home-based long-term care, care management aims to facilitate the independence of community-dwelling older adults and mitigate the escalation of their care needs. We examined the association between the types of care management (advanced vs. conventional) and the progression of care needs among recipients with moderate care needs and compared care services offered in care plans between care management types. Methods A retrospective, population-based observational study was conducted in Tsukuba City in Japan. The individual-level secondary data from the suburban municipal government was collected between May 2015 and March 2019. The primary outcome was the progression of care-need levels certificated in Japanese long-term care insurance. The exposure variable was advanced care management. First, we conducted propensity-score matching to adjust for differences in recipient characteristics. Second, we performed Kaplan–Meier survival analyses and log-rank tests, with the outcome measure being the progression of care-need levels. Third, Pearson's chi-square tests were performed to compare care services for recipients of advanced vs. conventional care management. Results Of the 1010 long-term care recipients, we selected 856 propensity score-matched recipients receiving advanced or conventional care management. The proportions of four-year cumulative progression-free survival in the groups receiving advanced and conventional care management were 82.2 % and 78.5 %, respectively (p = .69). The proportions of the groups with advanced and conventional care management were 17.1 % and 23.8 % using home-help services (p < .05), and 4.0 % and 8.2 % using community-based day care services (p < .05), respectively. Conclusions Advanced care management in home-based long-term care was not associated with a slowing of the progression of care needs among older adults with moderate care needs compared with conventional care management. There was a notable discrepancy in the use of care services, with the advanced care management group having lower rates of use of home-help services and community-based day care services compared with the conventional care management group.
