title: [Sleep deprivation effects on cognitive, psychomotor skills and its relationship with personal characteristics of resident doctors].
abstract: BACKGROUND
  In countries such as United States and European Nations changes have been proposed regarding to duty and academic structure of specialists in training, this implies adjustments in the norms concerning the number of hours a week that residents work. The main argument which has underpinned such transformations is based on the assumption that excessive working hours (more than 16 hours uninterrupted) cause cognitive and psychomotor disorders in residents.
  
  
  OBJECTIVE
  To evaluate the association between sleep deprivation and cognitive and psychomotor skills of a sample of residents of different specialties of Medicine.
  
  
  METHODS
  Longitudinal study with measurements pre and post shifts, in 31 residents of Medicine. The measured variables were: cognitive and psychomotor skills, demographic data and conditions of the shift, quality of sleep and psychopathology.
  
  
  RESULTS
  81% residents showed detriment in at least one of the tests, however, in psychomotor skills significant different results were found in CPR maneuvers between pre and post shift with an improvement in scores.
  
  
  CONCLUSIONS
  Sleep deprivation causes detriment of cognitive and psychomotor skills. While our results can't be generalized, they may constitute a precedent for possible changes in the working hours of medical residencies.
