Hospitalization for epistaxis: a population-based healthcare research study in Thuringia, Germany.

PURPOSE: Epistaxis is the most common ENT emergency. The aim was to determine population-based data on severe epistaxis needing inpatient treatment. METHODS: Retrospective population-based cohort study in the federal state Thuringia in 2016 performed on all 840 inpatients treated for epistaxis in otolaryngology departments (60.1% male, median age: 73 years; 63.9% under anticoagulation). The association between patients' and treatment characteristics and longer inpatient stay (≥ 4 days) as well as readmission for recurrent epistaxis was analyzed using univariable and multivariable statistics. RESULTS: The overall incidence of epistaxis needing inpatient treatment was higher for men (42 per 100,000) than for women (28 per 100,000). The highest incidence was reached for men > 85 years (222 per 100,000). Most important independent predictors for longer inpatient stay were localization of the bleeding not in the anterior nose (OR = 2.045; CI = 1.534-2.726), recurrent bleeding during inpatient treatment (OR = 2.142; CI = 1.508-3.042), no electrocoagulation (OR = 2.810; CI = 2.047-3.858), and blood transfusion (OR = 2.731; CI = 1.324-5.635). Independent predictors for later readmission because of recurrent epistaxis were male gender (OR = 1.756; CI = 1.155-2.668), oral anticoagulant use (OR = 1.731; CI = 1.046-2.865), and hereditary hemorrhagic telangiectasia (OR = 13.216; CI 5.102-34.231). CONCLUSIONS: Inpatient treatment of epistaxis seems to be variable in daily routine needing standardization by clinical guidelines and strategies to shorten inpatient treatment and to reduce the risk of readmission.
