Abstract

Background: Children's hospitals often do not have a high enough volume to justify providing radiologist staffing overnight, leading to hospitals employing teleradiology services to offer preliminary reports. There is limited literature related to discrepancies between preliminary teleradiology pediatric radiologists and final interpretations.

Purpose: The purpose of this study is to examine discrepancy rates for teleradiologists preliminarily interpreting pediatric exams at a children's hospital.

Material and methods: Eight thousand seven hundred seventy-eight consecutive preliminary reports issued by pediatric teleradiologists were reviewed. The hospital utilized a system in which local onsite radiologists rated the preliminary reports of teleradiologists following the interpretations as part of standard operating procedure. Discrepancies were also rated according to whether the discrepancy was actionable (judged to alter patient management by the final rater) or not. Rates were stratified by modality, preliminary teleradiologist reader, and final rater and compared to each using a normal approximation. The mean discrepancy rates were compared using a z test for proportions. Linear regression was applied to the effect of years of radiologist experience on the total and actionable discrepancy rates.

Results: The overall actionable discrepancy rate was 1.6%, similar to inter-observer discrepancy rates reported in other studies. There were no significant differences in the actionable discrepancy rates among teleradiologists. There was no correlation between years of experience and discrepancy rate for either the teleradiologists or the final raters.

Conclusion: Pediatric subspecialty teleradiologists issue reports that mirror discrepancy rates typical of radiologists who issue reports for emergent adult studies. Years of radiologist experience is not a predictor of discrepancy rate.
