영상의학과 전공의에 의한 응급실 컴퓨터단층촬영, 자기공명영상의 야간 예비 판독:얼마나 정확한가? = Overnight Preliminary Interpretationsof CT and MR Images by RadiologyResidents in ER: How Accurate Are They?

다국어 초록 (Multilingual Abstract)

Purpose: At many institutes in Korea, preliminary interpretations
of after-hours CT and MR images are performed by
radiology residents, with the attending radiologist’s reviewing
the interpretations the next day. The purpose of this
study was to assess the rate of discrepancy between residents’
interpretations and the final interpretations performed
by attending radiologists.
Methods: We reviewed the interpretations of 1381 CT and
404 MRI scans that were obtained at the emergency department
of our institute over three months. Any discrepancies
between the preliminary and final interpretations were categorized
as either major or minor discrepancies with a major
discrepancy defined as one resulting in a change in diagnosis
and treatment plans. We conducted patient follow-up via
a retrospective review of the medical records to evaluate the
clinical outcomes of the discrepancies.
Results: The rate of major discrepancies was 2.5%, and
the rate of minor discrepancies was 11.4%. Major discrepancies
led to a change in diagnosis or patient treatment
plans, but did not lead to any increase in patient morbidity.
Conclusion: The discrepancy rate at our institution was relatively
insignificant, and patient care at the emergency
department was not adversely affected by having radiology
residents interpret CT and MRI scans after-hours and the
attending radiologist review the interpretations the next
morning. Still, further efforts are needed in order to reduce
the frequency of major discrepancies.
