Diagnostic Yield of Outpatient Pediatric Echocardiograms: Impact of Indications and Specialty.
Multiple reports have shown that echocardiograms are neither cost-effective nor of high diagnostic yield for a number of indications. This study sought to evaluate the impact of indications and provider type on the diagnostic yield of first-time outpatient pediatric echocardiograms. All initial echocardiograms interpreted at our institution from February 2009 to December 2014 were reviewed retrospectively. Positive findings were defined as any abnormality of structure or function. Ordering physicians were grouped as Primary Care, Subspecialist, or Cardiologist. A cost analysis of cardiac consultation versus direct echocardiogram ordering was performed using 2014 Arkansas Medicaid office-based allowables. A total of 7854 echocardiograms had complete data and were included in the study. Median age was 7.2 years (range 2 days to 18.9 years). There were 1179 (15%) abnormal first-time echocardiograms. Diagnostic yields were particularly low for the indications of chest pain (4.9%), syncope (5.3%), and palpitations (9.1%). When ordered by the Cardiology group, echocardiographic yields were increased 35% for all indications (p < 0.001) and 100% for murmurs (p < 0.001) when compared to the Primary Care group. Cost analysis using the model of cardiology consultation rather than direct primary care echocardiogram ordering estimated a 19.6% reduction in medical costs for the most common indication, murmur. The diagnostic yield of outpatient pediatric echocardiograms is low for most indications. Overall, cardiologists had an improved diagnostic yield compared to other ordering physicians. For the indication of murmur, cardiology evaluation before echocardiogram might decrease unnecessary testing and healthcare expenses. This study provides a framework for improving resource utilization in the pediatric population.
