Randomized trial identifies high-risk older inpatients for hospital-associated disability, suggesting focused assessments.

To develop a simple risk stratification rule for identifying older adults at risk for hospital-associated disability.
Conducted a multicenter retrospective cohort study.
Included adults aged ≥ 65 years admitted to acute care hospitals.
Developed a four-item risk score based on age, CFS, MMSE, and admission type.
26.2% of participants (N=1292) developed hospital-associated disability.
The final score showed good discrimination (AUC 0.796; 95% CI 0.771–0.820).
HAD risk increased from < 5% in the lowest-risk group to ~ 50% in the highest-risk group.

Umegaki et al. (2026) studied this question.
