Changes in barriers to implementing early mobilization in the intensive care unit: a single center retrospective cohort study.

This study was undertaken to investigate the rate of mobilization, defined as a rehabilitation level of sitting on the edge of a bed or higher, and its association with changes in barriers in the intensive care unit (ICU). Consecutive patients from January 2016 to March 2019 admitted to the ICU, 18 years old or older, who did not meet exclusion criteria, were eligible. The primary outcome was the rate of mobilization. Barriers, their changes on a daily basis, and clinical outcomes, such as walking independence at hospital discharge, were also investigated. The association between the barriers and mobilization, and walking independence were analyzed by multivariate logistic regression analysis. During the study period, 177 patients were enrolled. Mobilization was achieved by 116 patients (66%) by the 7th ICU day. The barrier to mobilization was circulatory status on days 1 and 2, consciousness level on days 3 to 5, and medical staff factors on days 6 and 7. Multivariate analysis showed that consciousness level (OR: 0.38, p=0.01), and medical staff factors (OR: 0.49, p=0.01) were significantly associated with mobilization. By hospital discharge 125 patients (71%) could walk independently. Consciousness level was associated (OR: 0.52, p=0.04) with walking independence. In this study, over half of patients could achieve mobilization within the first 7 days. Barriers to mobilization in the ICU change over time. Consciousness level is significantly associated with both mobilization and independent walking at discharge.
