ObjectivesWe investigated delayed outcomes of patients with minor head injury, warfarin, and a normal initial head computer tomographic (CT) scan finding.MethodsWe conducted a single-center, retrospective study on such patients who were admitted. A second CT was not mandatory. International normalized ratios were classified into subtherapeutic, therapeutic, and supratherapeutic ranges. We traced them 2 weeks after discharge for delayed intracranial hemorrhage (ICH). Primary outcomes were proportions with ICH on second CT, fresh-frozen plasma (FFP) and/or vitamin K administration, and neurosurgical intervention. Secondary outcomes were hospital length of stay and the proportion with ICH 2 weeks after discharge. We explored differences in proportions of ICH during hospital stay among different strata (age ≥ 65 years, antiplatelet therapy, supratherapeutic international normalized ratio ranges, and FFP administration). Data were analyzed using descriptive statistics. P values less than .05 were considered statistically significant.ResultsWe recruited 298 patients. Of admissions (N = 295), 11 (3.7%) had a second CT, with one (0.3%) abnormality. There were 7 (2.4%) and 8 (2.7%) patients who received FFP and vitamin K, respectively. One patient (0.3%) required neurosurgical intervention. The median hospital length of stay was 3 (interquartile range, 2) days. No patients reattended 2 weeks after discharge. There were no statistically significant differences in the proportions of ICH during hospital stay among the 4 strata.ConclusionsDelayed ICH was rare with no predictive factors. Clinical monitoring before deciding on second CT was safe. The optimal period and mode of observation had yet to be determined.
