The Relationship Between Sleeping Hours and Psychomotor and Cognitive Skills Among Surgeons in Saudi Arabia

Abstract
Introduction: Sleep deprivation is a problem facing surgeons in many studies. However, few studies investigate sleep hours with psychomotor skills in Saudi Arabia. This study aimed to investigate sleep deprivation among surgeons and its effect on surgeons� performance in Jeddah, Saudi Arabia. Methodology: a total of 114 surgeons were recruited from governmental and private hospitals in Jeddah, Saudi Arabia. Participants mean age was 29.31. A self-administrated questioner that includes a 12-items Sleep Deprivation Impact (SDI) scale was distributed among participants. Linear regression and t-test were used in data analysis. P value of 0.05 was used as significant statistical level. The study was approved by Al-Batterjee Medical College. Results: 75% of surgeons lack adequate sleep hours (less than 7 hours). There was no relationship between sleeping hours and number of children, number of partners or gender. Almost all the psychomotor domains were not statistically different between surgeons who have inadequate or adequate sleeping hours. Conclusion: this study indicates that three-fourth surgeons in Saudi Arabia have inadequate sleep. However, there was no statistical significant relation between surgeons� sleeping hours and almost all the psychomotor domains. Keywords: On-call, Performance, Sleep Deprivation, Surgeons.
