Study patient baseline characteristics according to change in life-space assessment (LSA) score between baseline and post-hospitalization month 1. Improved group: ≥ 5 point increase; Unchanged group: fluctuate < 5 points; Decreased group: ≥ 5 point decline. LOS = length of stay; ADL = activities of daily living; PTA = prior to admission; LSA = life-space assessment. Welsh’s ANOVA analysis was completed comparing the Decreased, Unchanged, and Improved groups.
