About

The purpose of this study was to evaluate differences in cognitive functions at baseline and following night shift at a trauma center among faculty anesthesiologists.

Full description

Anesthesiology is one of the few health-care professions that often demands split-second decisions. This is especially true in a trauma setting where the situation in the operating room can change drastically in a few seconds. Anesthesiologists who cover trauma calls overnight are subject to long work shifts and demanding schedules that may adversely affect their performance. In combination with the disruption of circadian rhythm that can occur with night shift work, decline in performance from the long work shifts can lead to errors in judgment.

An anonymous questionnaire included two groups of different items were used. Items of the first group are about the personal data i.e. age, sex, marital status and parenting status, consumption behavior (tea, coffee, carbonated drinks, tobacco, anxiolytics, antidepressants, psychotropic agents and sport), and professional activity (number of extended worked shifts per month, number of weekends worked per month).

Items of the second group are related to the night shift itself i.e. number of cases, and the rest hours during the shift.

Psychomotor Vigilance Task, Karolinska Sleepiness Scale, Epworth Sleepiness Scale and Trail Making Test before and after the shift were performed.
