Abstract
Purpose: In order to identify factors related to independence of walking at discharge in patients on mechanical ventilators (MV) for more than 48 hours. Methods: This retrospective study was conducted in 81 of survivors on MV for more than 48 hours in ICU stay at our hospital from June 2016 to October 2017. Clinical data were statistically analyzed to detect factors related to the walking ability at discharge in such patients. The data were collected from medical records at ICU discharge. Results: There were significant differences in age, functional comorbidity index (FCI), delirium at ICU discharge and the functional status score for the ICU (FSS-ICU) at ICU discharge between the groups with and without walking independence. A multivariate logistic regression analysis showed that independent factors associated with independence of walking were the FSS-ICU at ICU discharge (OR: 1.21, 95%CI: 1.09-1.34, P<0.01) and FCI (OR: 0.62, 95%CI: 0.40-0.95, P=0.02). Conclusions: In survivors with prolonged MV, the independence of basic activities and FCI at ICU discharge contributed more to the independence of walking than the severity of illness in ICU.
