Methods: We conducted a cross-sectional survey in four municipalities of Ibaraki Prefecture in Japan, targeting dyads of care managers and primary caregivers of adults with care-need level ≥3 living at home. Latent class analysis (LCA) was applied to service-use indicators from care manager questionnaires. Then, caregiver questionnaires were linked to assess high caregiver burden, defined by the Burden Index of Caregivers-11 (BIC-11) and dichotomized at the median. Additional analyses examined five BIC-11 domains (time-dependent, emotional, existential, physical, service-related). Adjusted prevalence ratios (aPRs) were estimated using modified Poisson regression with robust variance, adjusting for patient and caregiver covariates. Results: Of 320 care manager  \nrespondents, LCA identified three subtypes: (1) outpatient/day services–centered, (2) multi-component home-visit services (mainly physician and nurse home visits), and (3) outpatient/ day rehabilitation–centered. After linkage and exclusion of missing data, 243 dyads were analyzed. Compared with the outpatient/day services subtype, the multi-component home-visit subtype was associated with a lower prevalence of high caregiver burden (aPR 0.66; 95% CI 0.46–0.95). Domain-specific analyses showed significantly lower emotional and existential burden in this group. Conclusions: Among adults with severe care needs at home, a multi-component home-visit service pattern was associated with lower caregiver burden, suggesting that appropriate service combinations may help mitigate caregiver strain.  \nAbstract citation ID: igaf122.4007  \nSERVICE-USE SUBTYPES AND CAREGIVER BURDEN  \nIN HOME-LIVING ADULTS WITH SEVERE CARE  \nNEEDS IN JAPAN  \nYu Sun, Masao Iwagami, Nobuo Sakata, Satoru Yoshie, Yoko Hamasaki, Shoichi Masumoto, Gen Nakayama, and Ryohei Goto, University of Tsukuba, Tsukuba, Ibaraki, Ibaraki, Japan  \nObjectives: As Japan transitions from hospital- to community-centered care, the burden on family caregivers is a growing concern.
