For its second decade, Taiwan's National 10‐Year Long‐Term Care Plan launched a policy of reinforcing home‐ and community‐based services (HCBSs) with a focus on reablement. This study aimed to (1) identify the distinct service use patterns of reablement‐embedded HCBS and (2) examine the effects of these service patterns on functional improvements among older care recipients, including among groups with different levels of care needs. We collected 2018 data from the Long‐Term Care Service Management System for care recipients in one county located in central Taiwan (N = 4735). Three recipient groups were assigned based on level of care needs. We included data on use of the following services: reablement, home care, respite care, applications for assistive devices and home environmental modifications, transportation to medical appointments and community‐based services. Outcome variables were measured by change scores between successive assessments of activities of daily living (ADL) and instrumental activities of daily living (IADL). Latent class analysis and multivariate linear regression analyses were used to analyse relationships between use patterns, participant subgroups and outcomes. Four subgroups of HCBS use patterns were found. Care recipients with low care needs had greater potential to improve their physical function in ADL through reablement‐embedded HCBS. Care recipients in the groups with low and high care needs showed overall benefits in functional improvements in ADL and IADL from personal care–based HCBS. Care recipients in the community‐based and multiple services–based use pattern subgroups showed the least improvement in physical function. Our study indicates that the effects of reablement‐embedded HCBS use strategies may vary among older adults with different levels of care needs. We recommend further research to examine how to design HCBS with a reablement focus to better fit the needs of those with moderate and high levels of care needs.
