Overnight Resident Interpretation of Torso CT at a Level 1 Trauma Center

At the authors' institution, there was a 2.0% discrepancy rate between residents' preliminary interpretations and attending radiologists' final interpretations of overnight torso computed tomography, with a small rate of additional intervention as a result of the major discrepancies. No adverse patient effects were directly attributable to discrepant interpretations. In discrepant cases, there was a 15% disagreement rate (17 of 112) between attending radiologists, suggesting some degree of interreader variance in interpretation. In addition, this disagreement rate among attending radiologists may imply that these cases were complex. Because there is educational value in overnight call, independent radiology resident coverage should continue.
