PurposeDiagnostic imaging has mirrored the steady growth of healthcare utilization in the USA. This has created greater opportunity for diagnostic errors, which can be costly in terms of morbidity and mortality as well as dollars and cents. The purposes of this study were to describe all return visits to a tertiary care urban pediatric emergency department (PED) resulting from diagnostic imaging discrepancies and to calculate the costs of these return visits.MethodsFrom July 2014 to February 2015, all children who underwent a diagnostic imaging study during an ED visit were assembled. Analysis was performed on all children who were called back and returned to the ED following a discrepant read. Direct and indirect costs to the patient, family, hospital, and society for these return visits were calculated.ResultsDuring the study period, 8310 diagnostic imaging studies were performed, with 207 (2.5%) discrepant reads. Among the discrepant reads, 37 (0.4% of total, 17.9% of discrepant) patients had a return visit to the ED for further management. Including ED charges, time and travel costs to the family, and costs of radiation exposure, return visits for radiologic discrepancies over this 8-month period cost a total of $84,686.47, averaging $2288.82 per patient.ConclusionsThough the overall diagnostic imaging discrepancy rate among our study population was low, the clinically significant discrepancies requiring return ED visits were potentially high risk, and costly for the patient, family, and healthcare system.
