Safety of early rehabilitation in patients with aneurysmal subarachnoid hemorrhage: A retrospective cohort study

Objective: To investigate the safety and efficacy of early rehabilitation in patients with aneurysmal subarachnoid hemorrhage (aSAH) patients. Methods: One hun-dred eleven patients with aSAH admitted between April 2015 and March 2019, were retrospectively evaluated. The early rehabilitation program was introduced in April 2017 to actively promote mobilization and walking training for aSAH patients. Therefore, patients were divided into two groups (The conventional group (n = 55) and the early rehabilitation group (n == 56). Clinical characteristics, mobili-zation progression, and treatment variables were analyzed. Complications (rebleed-ing, symptomatic cerebral vasospasm, hydrocephalus, disuse complications,) and a modified Rankin Scale (mRS) at 90 days were compared in two groups. Factors associated with favorable outcomes (mRS<2) at 90 days were also assessed. Results: The early rehabilitation group had a significantly shorter span to first walk-ing (9 vs. 5 days; P = 0.007). The prevalence of complications was not significantly increased in the early rehabilitation group. Approximately 40% of patients in both groups had pneumonia and urinary tract infections but significantly reduced antibi-otic-administration days (13 vs. 6 days; P < 0.001). mRS at 90 days also showed significant improvement in the early rehabilitation group (3 vs. 2; P=0.01). Multivar-iate logistic regression analysis of favorable outcomes associated that the adminis-tration of the early rehabilitation program has a significant independent factor (odds ratio, 3.03; 95% confidence interval, 1.1-8.37). Conclusions: Early rehabilitation for patients with aSAH can be feasible without increasing complication occurrences. The early rehabilitation program with active mobilization and walking training reduced antibiotic use and was associated with improved independence.
