To assess whether night-float rotation affected resident performance on the Council on Resident Education in Obstetrics and Gynecology (CREOG) in-service examination.
Review of annual CREOG in-service examination scores standardized for postgraduate year level (2001-2009) compared scores for residents on night float rotation at time of examination to those on non-night float rotation. Data were analyzed by linear mixed effects model.
Data were obtained for 72 residents, 20 of whom were on night float at time of at least one examination. One to four test scores were available for each resident (total 225 test scores). Average test score was 213 (SD = 20). The mean score for residents on night float was 214 (95% CI 207-221); the mean score for those on non-night float rotations was 212 (95% CI 208-216, p = 0.53). Sample size was sufficient to detect a difference of 12 points with 80% power.
Although night float rotations necessitate a complete reversal in sleep schedules, we found that night float service did not significantly affect scores On the annual in-service examination. To our knowledge, no studies have evaluated the impact of this schedule on test-taking ability.
评估夜间轮班是否会影响住院医师在妇产科住院医师教育委员会（CREOG）在职考试中的表现。
回顾2001 - 2009年按研究生年级标准化的年度CREOG在职考试成绩，比较考试时处于夜间轮班的住院医师与非夜间轮班住院医师的成绩。数据采用线性混合效应模型进行分析。
获取了72名住院医师的数据，其中20人在至少一次考试时处于夜间轮班。每位住院医师有1至4次考试成绩（共225个考试成绩）。平均考试成绩为213分（标准差 = 20）。夜间轮班住院医师的平均成绩为214分（95%置信区间207 - 221）；非夜间轮班住院医师的平均成绩为212分（95%置信区间208 - 216，p = 0.53）。样本量足以检测出12分的差异，检验效能为80%。
尽管夜间轮班需要完全颠倒睡眠时间表，但我们发现夜间轮班服务对年度在职考试成绩没有显著影响。据我们所知，尚无研究评估这种时间表对考试能力的影响。
