Abstract

Objective: Multiple reports have shown echocardiograms for certain indications are neither costeffective nor of high diagnostic yield. Given the ease with which tests can be obtained at a tertiary academic children’s hospital, our aims were to: (1) determine the diagnostic yield of inpatient studies by in-hospital location; (2) evaluate inpatient echocardiograms to determine indications and level of appropriateness; and (3) evaluate the frequency of cardiology involvement prior to those echocardiograms.
Design: All initial inpatient echocardiograms interpreted at our institution from February 2009 to December 2014 were reviewed retrospectively. Patient location was grouped as pediatric intensive care (PICU), emergency department (ED), and general floor.
Results: There were 727 first-time inpatient echocardiograms that met inclusion criteria. Pathology was identified in 25% of the study echocardiograms, with 11% of all studies demonstrating pathology that could alter patient management (moderate or severe pathology). The studies performed in the PICU and ED had more severe pathology compared with those from the general floor (P< .001, .003; respectively). Few echocardiograms were performed for rarely appropriate indications on the general floor (7%) and PICU (2.2%). Over 75% of general floor echocardiograms performed for a pathologic murmur yielded normal or incidental findings. Cardiology consultation was documented in only 7.5% of general floor studies.
Conclusion: The diagnostic yield of inpatient, first-time pediatric echocardiograms is relatively low. The majority of studies that identified pathology were performed on patients located in higher acuity units. General floor echocardiograms for murmurs had a low diagnostic yield, raising the question of cardiology consultation versus direct echocardiogram ordering for subjective physical exam signs.
