Knowledge of Appropriate Outpatient Pediatric Echocardiogram Ordering in Primary Care Physicians and Trainees

Appropriate Use Criteria (AUC) for the initial use of outpatient pediatric echocardiography were established to aid all clinicians in the evaluation of children with possible heart disease, and limit low diagnostic yield studies. We sought to (1) assess PCPs' and trainees' awareness of the AUC document; (2) compare their knowledge of appropriate echocardiogram ordering with that of pediatric cardiologists; and (3) identify additional medical and nonmedical factors affecting PCP echocardiogram ordering. An online survey with clinical scenarios derived from the AUC guidelines was distributed to PCPs and trainees in Arkansas, and pediatric cardiologists from Arkansas Children's Hospital and Cincinnati Children's Hospital Medical Center. Respondents were also asked to rate whether additional medical and nonmedical factors have “no,” “mild,” “moderate,” or “major” impact on PCP echocardiogram ordering. Survey data were collected from 148 respondents. Awareness of the AUC was significantly lower in PCPs (21.4%) and trainees (14%) than in pediatric cardiologists (90.5%, p <0.001). For all rarely appropriate clinical scenarios, cardiologists had stronger agreement with the AUC document (90.9%) than did the PCP group (50.3%) and trainees (53.3%, p <0.001). The strongest additional factors affecting PCP echocardiogram ordering were parental anxiety, difficulty distinguishing innocent from pathologic murmurs, and legal implications of a missed diagnosis. In conclusion, PCPs and trainees are largely unaware of the existence of the pediatric echocardiogram AUC. Educational strategies to improve appropriate echocardiogram ordering should address not only increasing awareness of AUC, but also other factors affecting decision-making.
