Sleep disorders among French anaesthesiologists and intensivists working in public hospitals: a self-reported electronic survey.

BACKGROUND: Sleep disorders can affect the health of physicians and patient outcomes. OBJECTIVES: To determine the prevalence of sleep disorders among French anaesthesiologists and intensivists working in a public hospital. DESIGN: A cross-sectional survey. SETTING: Anaesthesiologists and intensivists working in French public hospitals. MAIN OUTCOME MEASURES: Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) was used to assess the degree of excessive daytime sleepiness. RESULTS: Among 1504 responders, 677 (45%) physicians reported sleep disorders. The independent factors associated with sleep disorders were reporting of sleep disorders [odds ratio (OR) 12.04, 95% CI (95% confidence interval) 8.89 to 16.46], sleep time less than 7 h (OR 8.86, 95% CI 6.50 to 12.20), work stress (OR 2.04, 95% CI 1.49 to 2.83), stress at home (OR 1.77, 95% CI 1.24 to 2.53), anxiolytic use (OR 3.69, 95% CI 2.23 to 6.25), psychotropic drug use (OR 3.91, 95% CI 1.51 to 11.52) and excessive daytime sleepiness (OR 1.81, 95% CI 1.34 to 2.45). Six hundred and seventy-six (44%) responders reported excessive daytime sleepiness during their professional activity. The independent factors associated with excessive daytime sleepiness were female sex (OR 1.86, 95% CI 1.49 to 2.34), tea consumption (OR 1.47, 95% CI 1.14 to 1.91), regular practice of nap (OR 1.68, 95% CI 1.34 to 2.09), stress at home (OR 1.31, 95% CI 1.02 to 1.68), more than four extended work shifts monthly (OR 1.25, 95% CI 1.01 to 1.56) and sleep disorders (OR 1.73, 95% CI 1.31 to 2.29). Reporting sleep disorder duration and a sleep time less than 7 h were the two major risk factors for sleep disorders. Female sex was the major risk factor for excessive daytime sleepiness. CONCLUSION: French anaesthesiologists did not report more sleep disorders than the general population, but their alertness is impaired by a factor of two.
