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

To investigate the safety and efficacy of early rehabilitation in patients with aneurysmal subarachnoid hemorrhage (aSAH) patients. One hundred 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, mobilization progression, and treatment variables were analyzed. Complications (rebleeding, 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. The early rehabilitation group had a significantly shorter span to first walking (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 antibiotic-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). Multivariate logistic regression analysis of favorable outcomes associated that the administration of the early rehabilitation program has a significant independent factor (odds ratio, 3.03; 95% confidence interval, 1.1-8.37). 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.
