Impact of Preexisting Diabetes on Activities of Daily Living Independence at Hospital Discharge in Critically Ill Patients: A Prospective Cohort Study

Year: 2026

Abstract: Background: Diabetes mellitus is known to affect the prognosis of critically ill patients; however, its impact on independence in activities of daily living (ADL) at hospital dis-charge remains unclear. This study aimed to investigate whether preexisting diabetes is associated with reduced ADL independence at hospital discharge among critically ill patients. Methods: In this prospective cohort study, 423 adult intensive care unit (ICU) patients who were admit-ted for ≥48 h were enrolled and categorized by the presence or absence of diabetes. Primary outcomes included time to achieve walking independence (unassisted walking over 50 m) and the Barthel Index at discharge. Secondary outcomes were handgrip strength, ICU length of stay, and highest ICU Mobility Scale (IMS) scores. Multivariable analyses adjusted for age, illness severity, and other confounders. Results: Among the 101 patients with diabetes, time to achieve walking independence at discharge was significantly longer compared to those without diabetes (p = 0.013). The diabetes group also had a lower Barthel Index (p = 0.020), longer ICU stays (p = 0.003), weaker handgrip strength (p = 0.041), and lower maximum IMS scores (p = 0.002). Multivariable analysis confirmed that diabetes was independently associated with reduced ADL independence and poorer physical function at discharge. Conclusions: Preexisting diabetes is an independent predictor of impaired ADL independence in critically ill patients. These findings highlight the importance of early and individualized rehabilitation strategies for patients with diabetes in the ICU.
