Implementation of a Pediatric Chest Pain Local Consensus Guideline Decreases the Total Tests Performed Without Negatively Affecting the Yield of Abnormal Cardiac Results

Pediatric chest pain is common and though usually benign often leads to unnecessary diagnostic testing. There is limited evidence as to whether a local consensus guideline can decrease testing frequency without negatively affecting the overall yield. In addition, it is unknown whether the addition of pulmonary function testing to a cardiopulmonary exercise test increases the diagnostic yield in pediatric patients with chest pain. A retrospective chart review was performed on all new pediatric patients who presented with chest pain at our academic center’s pediatric cardiology clinic 18 months before and after the implementation of a standard management guideline. Data from the encounter-associated echocardiogram, cardiopulmonary exercise test, and pulmonary function test, when available, were analyzed. There were no significant differences in patient volume or demographic characteristics in the 18 months before ( n = 768) and after ( n = 778) guideline implementation. There were significant reductions in the number of ordered echocardiograms ( n = 131; 17% vs. n = 75; 9.6%, p
