The clinical effectiveness of hemostatic therapy is unclear.<\/jats:p><\/jats:sec>Objective<\/jats:title>To compare the clinical and radiological outcomes of DOAC-associated ICH treated with prothrombin complex concentrate (PCC) vs conservative management.<\/jats:p><\/jats:sec>Design, Setting, and Participants<\/jats:title>In this population-based, propensity score\u2013weighted retrospective cohort study, patients who developed DOAC-associated ICH from January 1, 2016, to December 31, 2021, in Hong Kong were identified. The outcomes of patients who received 25 to 50 IU\/kg PCC with those who received no hemostatic agents were compared. Data were analyzed from May 1, 2022, to June 30, 2023.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>The primary outcome was modified Rankin scale of 0 to 3 or returning to baseline functional status at 3 months. Secondary outcomes were mortality at 90 days, in-hospital mortality, and hematoma expansion. Weighted logistic regression was performed to evaluate the association of PCC with study outcomes. In unweighted logistic regression models, factors associated with good neurological outcome and hematoma expansion in DOAC-associated ICH were identified.<\/jats:p><\/jats:sec>Results<\/jats:title>A total of 232 patients with DOAC-associated ICH, with a mean (SD) age of 77.2 (9.3) years and 101 (44%) female patients, were included. Among these, 116 (50%) received conservative treatment and 102 (44%) received PCC. Overall, 74 patients (31%) patients had good neurological recovery and 92 (39%) died within 90 days. Median (IQR) baseline hematoma volume was 21.7 mL (3.6-66.1 mL). Compared with conservative management, PCC was not associated with improved neurological recovery (adjusted odds ratio [aOR], 0.62; 95% CI, 0.33-1.16; P<\/jats:italic>\u2009=\u2009.14), mortality at 90 days (aOR, 1.03; 95% CI, 0.70-1.53; P<\/jats:italic>\u2009=\u2009.88), in-hospital mortality (aOR, 1.11; 95% CI, 0.69-1.79; P<\/jats:italic>\u2009=\u2009.66), or reduced hematoma expansion (aOR, 0.94; 95% CI, 0.38-2.31; P<\/jats:italic>\u2009=\u2009.90). Higher baseline hematoma volume, lower Glasgow coma scale, and intraventricular hemorrhage were associated with lower odds of good neurological outcome but not hematoma expansion.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this cohort study, Chinese patients with DOAC-associated ICH had large baseline hematoma volumes and high rates of mortality and functional disability. PCC treatment was not associated with improved functional outcome, hematoma expansion, or mortality. Further studies on novel hemostatic agents as well as neurosurgical and adjunctive medical therapies are needed to identify the best management algorithm for DOAC-associated ICH.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamanetworkopen.2023.54916","type":"journal-article","created":{"date-parts":[[2024,2,6]],"date-time":"2024-02-06T17:39:24Z","timestamp":1707241164000},"page":"e2354916","source":"Crossref","is-referenced-by-count":16,"title":["Prothrombin
