A prospective, case control study at a university-affiliated, academic pediatric emergency department was undertaken to determine the clinical impact and cost of false-positive preliminary radiograph interpretations and to compare the cost of false-positive interpretations with the estimated cost of a 24-hour on-site pediatric radiologist.
Data were collected on all patients undergoing radiography of the chest, abdomen, lateral (soft tissue) neck, cervical spine, or extremities during a 5-month period.
A total of 1,471 radiograph examinations was performed, and 200 (14%) misinterpretations (false-positive and false-negative) by the pediatric emergency medicine physicians were identified.
As reported previously, 20 (10%) of the false-negative interpretations were noted to be clinically significant.
In the current analysis, 103 (7%) false-positive radiograph interpretations were identified.
False-positive interpretations were noted more frequently (14%) for soft tissue lateral neck radiographs than for any other radiograph type.
Of the 103 total false-positive radiographs, nine (0.6%) resulted in an increased patient cost totaling $764.75.
These data show that false-positive radiograph interpretations have limited economic and clinical impact.
