Objectives: We aimed to examine the association between intrinsic capacity (IC) and adverse outcomes of hospitalization. Design: A prospective observational cohort study. Setting and participants: We recruited patients aged 65 years or older who were admitted to the geriatric ward of an acute hospital between Oct 2019 and Sep 2022. Measurements: Each of the five IC domains (locomotion, cognition, vitality, sensory, and psychological capacity) was graded into three levels, and the composite IC score was calculated (0, lowest; 10, highest). Hospital-related outcomes were defined as in-hospital death, hospital-associated complications (HACs), length of hospital stay, and frequency of discharge to home. Results: In total, 296 individuals (mean age 84.7 ± 5.4 years, 42.7 % males) were analyzed. Mean composite IC score was 6.5 ± 1.8, and 95.6 % of participants had impairment in at least one IC domain. A higher composite IC score was independently associated with lower frequency of in-hospital death (odds ratio [OR] 0.59) and HACs (OR 0.71), higher frequency of discharge to home (OR 1.50), and shorter length of hospital stay (β = −0.24, p |
