Background: Protracted bacterial bronchitis (PBB) is a common cause of chronic wet cough in children. However, it is often misdiagnosed and inappropriately treated in clinical practices. This study aims to investigate the current diagnosis and management of PBB among Chinese pediatricians.
Methods: An electronic questionnaire designed to assess the diagnosis and management of PBB was sent to pediatricians in China.
Results: A total of 1,022 pediatricians completed the questionnaire. Most (68.8%) of the pediatricians diagnosed PBB in compliance with the guidelines, 44.3% and 24.5% of them followed microbiology-based and clinical-based diagnosis criteria, respectively. Only 40.4% of the pediatricians chose amoxicillin-clavulanate as the first-line antibiotic for PBB treatment, 23.7% and 23.5% of them chose third-generation cephalosporins and macrolides, respectively. The majority of pediatricians (75.4%) reported 2-4 weeks of antibiotics course, 19.3% of them prescribed a shorter course and 5% of them selected a longer course. Only 26.3% of the pediatricians performed combined investigations of chest high-resolution computed tomography scan (c-HRCT), bronchoscopy, and immunological tests for recurrences of PBB. Compared with general pediatricians (GP), pediatric pulmonologists (PP) preferred microbiology-based diagnosis criteria, prescribed more amoxicillin-clavulanate, and performed more investigations for recurrent patients (P<0.05).
Conclusions: The majority of Chinese pediatricians diagnosed PBB in compliance with guidelines. However, the reasonable antibiotics applications and the investigations for recurrent PBB need to be improved.
