Objective: To compare the clinical acumen of paediatric cardiovascular examination between various hospital paediatrician grades. Design: Prospective data collection of clinical and echocardiography findings on paediatric echocardiography referrals. Setting and patients: All paediatric patients (birth - 14 years) referred for echocardiography, in a regional hospital catering for the island population of Malta. Echocardiography was carried out by three paediatricians with tertiary training in this technique. Main outcome measures: Pre-echocardiography clinical diagnoses were compared with echocardiography results according to grade of referring hospital doctor (ranging from houseman to consultant). Both normal and abnormal hearts at echocardiography were included. Results: Echocardiographers had the highest clinical accuracy and the highest attempts at reaching a clinical diagnosis. Accuracy and attempts at diagnosis decreased as doctor's hospital grade decreased, from consultant to houseman. Ventricular septal defect was the most easily diagnosed lesion. Atrial septal defect was often misdiagnosed as pulmonary stenosis.peer-reviewe
