Aim This longitudinal study aimed to determine whether categorization by the Dementia Assessment Sheet for Community‐based Integrated Care System 8‐items (DASC‐8) is associated with risk of frailty onset, disability, and mortality. Methods We analyzed longitudinal data from outpatients aged 65 years and older evaluated for the DASC‐8 at the Frailty Clinic. The outcomes during the 3‐year follow‐up period were (Study A) frailty onset (Kihon Checklist ≥8) and (Study B) disability (new certification of nursing care needs) or mortality. Multivariate Cox regression analyses were performed to examine independent associations between the DASC‐8 category and outcomes, and hazard ratios and 95% confidence intervals (CIs) were calculated after adjustment for age, sex, and the presence or absence of diabetes, hypertension, and dyslipidemia. Results (Study A) Out of the 216 patients without frailty in Categories I or II at baseline, 40 (20.4%) and 11 (55.0%) developed frailty, respectively. The adjusted hazard ratio was 3.62 (95% CI: 1.69–7.76, P
