Evidence linking them to post-discharge outcomes is limited, but could support targeted rehabilitation efforts. Aim To assess whether ADL ability measures and cognitive screening at hospital discharge were associated with post-discharge ADL ability, health-related quality of life (HRQoL) and return to work. Methods This prospective cohort study included 200 OHCA survivors admitted to Aarhus University Hospital. Self-reported ADL ability was measured using the Activities of Daily Living Interview (ADL-I). Observed ADL ability was measured with the Assessment of Motor and Process Skills (AMPS), dichotomised into age-matched or below-ability. Cognitive function was assessed with Montreal Cognitive Assessment (MoCA). Multivariable regressions, with multiple imputation, analysed associations between variables and outcomes, adjusting for age, sex, and comorbidities. Results Adjusted analyses showed significant associations between personal ADL-I (βadjusted = 0.3, 95%CI: 0.2;0.5) and AMPS (βadjusted = -0.6, 95%CI:-1.2;-0.03) at discharge and self-reported ADL ability six months after cardiac arrest.
