OBJECTIVES: To conduct a pilot study assessing a neonatologist's accuracy in diagnosing patent ductus arteriosus (PDA) using compact, portable ultrasound after limited training.
STUDY DESIGN: Prospective study of premature infants scheduled for echocardiography for suspected PDA. A neonatologist with limited training performed study exams before scheduled exams. Sensitivity and specificity were calculated, compared to the scheduled echocardiogram interpreted by a cardiologist.
RESULTS: There were 24 exams. Compared to the scheduled exam, the neonatologist's exam had sensitivity 69% (95% confidence interval (CI), 41 to 89%) and specificity 88% (95% CI, 47 to 99%). When a cardiologist interpreted the study exams, the sensitivity was 87% (95% CI, 60 to 98%) and specificity 71% (95% CI, 29 to 96%).
CONCLUSION: A neonatologist with limited training was able to detect PDA with moderate success. A more rigorous training process or real-time transmission with cardiologist interpretation may substantially improve accuracy. Institutions with experienced technicians and on-site pediatric cardiologists may not gain from intensive training of neonatologists, but hospitals where diagnosis and treatment of PDA would be delayed may benefit from such processes.
