  1. Analyses for short-term mechanical ventilation (n = 312) and DRG 541/542 (n = 214) patients. aValues from two-sample t-tests are expressed as means (standard deviation). bValues are expressed as mean (95% confidence interval) based on linear-mixed effects models. Both unadjusted and linear mixed-effects models included imputed values and adjusted for day 1 APS, admitting service, pre-admission IADLs, pre-admission Charlson score, age ≥ 65 years, and education status. ADL, activity of daily living; DRG, diagnosis related group; IADL, instrumental activity of daily living; SF-36, Short Form 36-item questionnaire.
