Abstract Background Although supportive care is the mainstay management for acute bronchiolitis, non–evidence-based diagnostic testing and medications remain common in emergency departments (EDs). Objective Our aim was to compare emergency physicians (EPs) and pediatricians practice patterns in the management of acute bronchiolitis in the ED. Methods A cross-sectional study was conducted by using registration and claims datasets from 2008 to 2011. Patients with acute bronchiolitis were divided into EP group and pediatrician group. Results A total of 2174 patients were enrolled. The diagnostic tests used, including chest x-ray (63.7% vs. 46%; adjusted odds ratio [OR] = 2.27; 95% CI 1.77–2.91), complete blood count (33.2% vs. 21.8%; adjusted OR = 1.74; 95% CI 1.33–2.26), C-reactive protein (35.1% vs. 22.6%; adjusted OR = 1.79; 95% CI 1.38–2.33), blood culture (23.9% vs. 14.3%; adjusted OR = 1.79; 95% CI 1.33–2.39), and arterial blood gas (3.7% vs. 1.8%, adjusted OR = 2.38; 95% CI 1.21–4.67), were higher in the EP group than in the pediatrician group. Intravenous fluid administration was also higher in the EP group (20.8% vs. 3.5%; adjusted OR = 7.49; 95% CI 5.12–10.8). In addition, EPs more frequently arranged for hospital admissions (36% vs. 19.5%; adjusted OR = 2.51; 95% CI 1.15–3.26). Conclusions Both EPs and pediatricians had high rates of ordering diagnostic testing for acute bronchiolitis patients in ED. Compared with pediatricians, EPs used more diagnostic tests for the patients with acute bronchiolitis in ED.
