Abstract :
Background: The present study aimed to investigate the effects of
work shifts and mental workload on chronic fatigue among female
nurses in Intensive Care Units of selected hospitals in Shiraz.
Methods: The participants in this cross-sectional study were 118
female nurses working in Intensive Care Units of three hosptals
in Shiraz with an average age of 304.8± years. SP (Samn-Perelli)
Mental fatigue scale and NASA task load index were rated for
two weeks at the beginning and end of each work shift. The
Checklist Individual Strenght (CIS) questionnaire was completed
to assess the fatigue during the last two weeks.
Results: Mean score of chronic fatigue was 69.2±13. Menal fatigue
and mental workload per shift were significantly correlated with
work shifts (P=0.001). Mental workload (P=0.006, r=0.24) and
mental fatigue caused by work shifts (P=0.001, r=0.42) were also
significantly correlated with chronic fatigue.
Conclusion: The results of the study showed that mental workload
and work shifts influence the nurses’ fatigue in Intensive Care
Units. Therefore, using intervention strategies to reduce mental
work load and modification of shift work system in this group
seems to be necessary.
