Odds ratios from multilevel models adjusted for patients’ age; sex; race/ethnicity; dual eligibility; Medicare original reason for entitlement; number of hospitalizations over the prior year; comorbidities (hierarchical condition categories); and index hospitalization diagnostic category, primary procedure (if applicable), length of stay, receipt of dialysis, and intensive or coronary care unit utilization.
Mobility and self-care domains created using items from Home Health OASIS. The mobility domain included 3 items related to transfers and ambulation/locomotion. The self-care domain included 7 items related to feeding, preparing light meals, grooming, dressing, bathing, and toilet hygiene.
Cognitive categories created using 4 OASIS items.
Assistance domain created using 1 item from the OASIS.
