Hospitalized older adults recovering from critical illness after transition of care out of an intensive care unit (ICU) are often inactive, which may affect discharge disposition and hospital length of stay (LOS). The current study explored relationships between early post-ICU activity, discharge disposition, and LOS. Actigraphy measured post-ICU daytime and nighttime activity (mean activity counts/min). Prospective chart review provided discharge disposition and LOS (days). Independent samples t tests compared post-ICU daytime activity by discharge disposition. Multivariate regression examined associations between post-ICU activity and LOS. Post-ICU daytime activity was greater among those discharged home (54.42 [SD = 29.3 counts/min]) than those discharged to a facility (33.26 [SD = 24.26 counts/min]): t(26) = 2.054, p = 0.050). Lower post-ICU daytime activity was associated with longer LOS (β = -0.322, p = 0.041). Future research should investigate whether post-ICU daytime inactivity during hospitalization is a modifiable risk factor for worse outcomes among older adults discharged from the ICU.
