Abstract
Background: Prevention of hematoma enlargement in oral anticoagulation-associated intracerebral hemorrhage (OAC-ICH) focuses on blood pressure (BP) reduction and OAC reversal. We investigated whether treatment efficiency and clinical outcomes differ between OAC-ICH patients admitted outside versus during regular working hours. Methods: Based on pooled data of multicenter cohort studies, we grouped OAC-ICH patients (vitamin K antagonist [VKA], non-vitamin K oral anticoagulant [NOAC]) according to on- vs. off-hour admission. Primary outcome was the functional outcome using the modified Rankin scale (mRS) dichotomized into favorable (mRS 0–3) and unfavorable (mRS 4–6) and mortality at 3 months. Secondary outcome measures included the occurrence of hematoma enlargement, the proportions of patients with systolic BP Results: The study population consisted of 76/126 NOAC-ICH patients and 1,005/1,470 VKA patients presenting during off-hours. Functional outcome and mortality rates were not significantly different among PSM patients with VKA-ICH and NOAC-ICH during on- vs. off-hours (mRS 4–6 VKA-ICH: on-hour: 239/357 [66.9%] vs. 253/363 [69.7%] off-hour; p = 0.43; NOAC-ICH: on-hour 26/42 [61.9%] vs. off-hour: 37/57 [64.9%]; p = 0.76; mRS 6 VKA-ICH: on-hour: 127/357 [35.6%] vs. off-hour: 148/363 [40.8%]; p = 0.15; NOAC-ICH: on-hour 17/42 [40.5%] vs. off-hour: 16/57 [28.1%]; p = 0.20). There were no differences detectable regarding the secondary outcome measures (i.e., hematoma enlargement, the proportion of patients who achieved systolic BP levels Conclusion: Our study implies that BP reduction and anticoagulation reversal management are well established and associated with similar rates of hematoma enlargement and clinical outcomes in on- vs. off-hour admitted OAC-ICH patients.Keywords
