PURPOSE: Reports have shown that sleep deprivation is common among medical trainees despite implementation of work hour restrictions. Many studies have shown the negative effect of sleep deprivation on medical trainees. We conducted an anonymous survey to determine baseline sleep hygiene, chronotype, and sleep quality of entering medical trainees at Tulane University residency programs.
METHODS: A cross-sectional survey of our trainees prior to the start of the training was conducted. The sleep quality was determined using the validated Pittsburg Sleep Quality Index (PSQI). The sleep efficiency (SE, %) was calculated from the individual’s PSQI data. Morningness-Eveningness and sleep hygiene questionnaires were used to describe individuals’ chronotype and sleep-related behaviors, respectively.
RESULTS: Fifty-seven out of 61 enrolled subjects completed all three questionnaires. Fifty-five percent of entering trainees had a PSQI > 5, indicating poor sleep quality. The mean PSQI was 5.8±3.0. The mean SE was 90.8±7.0%. The PSQI demonstrated a positive correlation with irregular bedtime, irregular rise time, stimulating activities (playing video game and using internet) prior to bed and going to bed with stress (r = 0.27, 0.26, 0.44, and 0.37 respectively, p<0.05). There was a negative correlation between SE and stimulating activities, physical exercise and alcohol/caffeine/tobacco use prior to bed, as well as with spending excessive time in bed (r = -0.34, -0.34, -0.31 and -0.26 respectively, p<0.05). Chronotype did not correlate with sleep quality or efficiency.
CONCLUSIONS: Over half of our trainees had poor sleep quality prior to the beginning of their training. The quality of pre-training sleep was associated with several modifiable sleep-related behaviors. Thus, consideration should be given to identify sleep problems early in individual trainees to inform them on healthy sleep behaviors.
CLINICAL IMPLICATIONS: Inappropritae sleep-related behaviors can be identified at the beginning of the training. This infomation may provide a guidance to the individual trainees to develop good sleep behaviors.
