Objective

To study the relationship between residents' pre-test available study time and subsequent examination performance.

Methods

We compiled rotation schedules and in-training examination performances for all residents enrolled in the two University of Texas Medical School-Houston obstetrics and gynecology residencies between 1993 and 1995. Services on which the residents had rotated were ranked by surveying all enrolled residents as to their perceived available study time while on those services. A mean available study time rating was computed for each service, which was used to describe each resident's schedule. Pearson correlations between available preparation-time preceding the in-trainng examination and examination performance were calculated. “Tough” and “easy” rotation subgroups were defined; two-tailed t tests were performed to compare the in-training examination performance of these subgroups.

Results

No significant correlation was found between available study time and subsequent examination scores beyond that which could be accounted for by year of training. Scores of residents in the “tough” subgroup were not significantly different from those in the “easy” subgroup on any examination performance measure. For correlations at the one-tailed .05 level, statistical power to detect relationships predicting 16% of variance ranges from approximately 85% for samples of 42 to 68% for samples of 27.

Conclusion

Residents' in-training examination performance was not significantly affected by their service obligations. Altering resident monthly schedules is not likely to improve in-training examination performance.

    Investigations on any association between work hours, sleep hours, and performance on standardized examinations have yielded conflicting results. Some studies of surgical and obstetric residents had shown no significant correlation between duty hours [10] or call status [11]. A more recent study has reported improvement in standardized test scores following a reduction in junior surgical residents’ work hours [2].
