Abstract: It is unclear whether antihypertensive treatment should be indicated after subarachnoid hemorrhage (SAH). Hence, we investigated the impact of blood pressure on inpatient outcomes after SAH rehabilitation.This retrospective cross-sectional study analyzed data of SAH inpatients, as obtained from the Japan Association of Rehabilitation Database for inpatients undergoing SAH rehabilitation. Inpatients admitted to a conventional ward with a diagnosis of cerebrovascular disease were voluntarily registered in this database between January 2006 and December 2013 from hospitals in Japan. Patients were categorized into hypertensive and non-hypertensive populations and assessed using the Barthel Index (BI) and the total BI score at hospital discharge. We compared the independent population (patients with the highest score for each activity) with its non-independent counterpart. Data on the patients' age, BI score on admission, total BI score, BI score increase, daily BI score increase, hospitalization duration, BI activities, patients' sex, and Brunnstrom recovery stage were compared.Eighty-eight patients with SAH were analyzed; 43 were hypertensive and 45 non-hypertensive. Hypertension was associated with increased non-independence levels (hypertensive versus non-hypertensive patients, transfers [bed to chair and back]: 15 versus 24, P = .03, odds ratio (OR) = 2.532 (95% confidence interval [CI], 1.065-6.024); toilet use: 15 versus 24, P = .03, OR = 2.532 (95% CI, 1.065-6.024); bathing: 23 versus 34, P = .0061, OR = 3.623 (95% CI, 1.414-9.259); stair climbing: 22 versus 31, P = .03, OR = 2.703 (95% CI, 1.114-6.579); and bladder control: 14 versus 24, P = .02, OR = 2.801 (95% CI, 1.170-6.711)). The total BI score of the hypertensive inpatients at discharge was lower than that of their non-hypertensive counterparts (0-75 versus 80-100, 30 versus 19, P = .03). Moreover, the BI score increase per day was significantly lower in the hypertensive group than in the non-hypertensive group (.67 versus 1.8, P = .02). The hypertensive group also had a significantly longer duration of hospitalization than the hypertensive group (52 versus 30 days, P = .02).Hypertension was associated with longer hospitalization and poorer outcomes post-discharge, suggesting the importance of strict blood pressure control in patients who have experienced SAH.
