Abstract

Epistaxis is one of the common causes of emergency department (ED) visits. However, most cases are not severe and undergo an unnecessary medical evaluation, especially in non-traumatic epistaxis. This study investigated how many patients require a definite observational unit (DOU) and what factors are associated with DOU among non-traumatic epistaxis patients. This retrospective observational study included 1197 non-traumatic epistaxis patients who visited the ED from January 2016 to December 2020. Multiple logistic regression analysis was performed to evaluate the association between risk factors and DOU care. In addition, the receiver operating characteristic (ROC) curve for predicting DOU care was analyzed to estimate the diagnostic ability of risk factors. A total number of 1122 patients with non-traumatic epistaxis were included in the final analysis. Among them, 41 (3.65%) patients needed DOU care. Male sex (odds ratio (OR) = 3.606, p = 0.003), hypertension (OR = 2.362, p = 0.020), inter-hospital transfer (OR = 2.358, p = 0.039), verbal mental status (OR = 29.436, p = 0.035), hemoglobin (Hb) level (OR = 0.724, p < 0.001), revisit after initial discharge for epistaxis (OR = 8.813, p < 0.001), and delayed ED arrival (≥180 min) (OR = 2.451, p = 0.030) were significant factors for DOU care. In addition, the area under the curve of the multiple logistic regression model for predicting DOU care was 0.870. Among the patients who visited ED due to non-traumatic epistaxis, only 3.65% of patients required DOU care. Male sex, mental status, Hb level, ED revisit after initial discharge, inter-hospital transfer and delayed ED arrival (>180 min) were associated with DOU care. These findings will help to triage epistaxis patients before they visit the ED.
