The Effect of Fatigue on Resident Performance

Abstract
Rested and fatigued residents (14) read a set of 25 test radiographs on 2 separate occasions about 1 mo. apart. The radiographs were made with a partial chest phantom using pulmonary nodules as test objects. Seven rested and 7 fatigued residents read the radiographs, and 1 mo. later the order of fatigue was reversed. Fatigued residents had worked a minimum of 15 consecutive hours before their interpretations. Performance did not deteriorate with fatigue and the nodule detection rate was almost identical on both occasions.
