Association between out-of-bed mobilization and complications of immobility in acute phase of severe stroke: A retrospective observational study.

BACKGROUND

Medical complications often occur, particularly in the acute phase of severe stroke, and lead to poor outcomes. However, it is unclear whether out-of-bed mobilization (OM) reduces such complications or not in the acute phase of severe stroke. Thus, we investigated the association between OM and complications of immobility in the acute phase of severe stroke.

METHODS

We enrolled 407 patients diagnosed with ischemic stroke or intracerebral hemorrhage and patients with modified Rankin Scale 5 at discharge in this study. Patients were divided into two groups: OM (303 patients) and bed rest (BR; 104 patients) at discharge based on their medical records. Complications of immobility (such as pneumonia, urinary tract infection, pressure sore, and falls) during hospitalization in each group were recorded.

RESULTS

The total complication rate of immobility, incidence of pneumonia, and the incidence of pressure sores were significantly lower in the OM group than in the BR group [60.7% vs. 88.5%, 45.5% vs. 62.5%, and 3.6% vs. 12.5%; odds ratio, 0.20, 0.50, and 0.26; and 95% confidence intervals, 0.11-0.39, 0.32-0.79, and 0.11-0.61, respectively]. Urinary tract infection and falls did not differ significantly between the two groups.

CONCLUSIONS

In the acute phase of severe stroke, OM was significantly associated with a lower risk of total complication rate of immobility, incidence of pneumonia, and incidence of pressure sore without increasing falls.
