Received: November 03, 2017; Accepted: November 28, 2017 ABSTRACT Background: Exposure to shift works and especially to night shifts goes against the circadian rhythm of the social man which brings about a multitude of disruptive effects on health such as sleep disturbances, day sleepiness, decreased cognitive performance, fatigue, increased risk of accidents, poor quality of life, and vigilance troubles. Choice RT test is related to more components of cognitive function. [...]simple and choice RT tests could serve as bedside measurements reflecting cognitive function. The instrument used for data collection was the "standard shift work index," they reported the lowest mean score in the items of job satisfaction, quality and quantity of sleep, with more frequent chronic fatigue, psychological, and cardiovascular symptoms in comparison with the day shift workers, in a statistically significant way. [20] We hypothesized that the quality of sleep will be affected in night shift workers which in turn alter their cognition using RT, as there are very less number of works conducted in hospital shift nurses, who bound to shift work by their profession having altered circadian rhythm, we conducted the study aiming to assess influence of altered circadian rhythm on quality of sleep and its association with cognition using RT in shift nurses.
