Sleep disorders are one of the most important causes of fatigue in nurses. The present study aimed to determine the level of occupational fatigue and sleep quality among nurses working in various wards of public hospitals.</span><br> <strong><span style="letter-spacing:-.1pt;background:#2D7F8F;"><span style="color:white;">&nbsp;Materials & Methods:</span></span></strong> <span style="letter-spacing:-.1pt;"><span style="color:black;">This cross-sectional study was conducted on 234 nurses working in diverse wards of the two public hospitals affiliated to Ilam University of Medical Sciences, Iran selected by the convenience sampling method. The data were collected using a demographic questionnaire, Occupational Fatigue Exhaustion Recovery scale, and Pittsburgh Sleep Quality Index. Finally, the data were analyzed by descriptive statistics, independent t-test, and one-way analysis of variance using the SPSS software version 21.</span></span><br> <strong><span style="background:#2D7F8F;"><span style="color:white;">&nbsp;Results: </span></span></strong>&nbsp;<span style="letter-spacing:-.1pt;"><span style="color:black;">The mean sleep quality index of the nurses working in the nursing station was at the appropriate level (3.83&plusmn;2.32), whereas the nurses working in other wards had an unsuitable level of sleep quality index. Moreover, the mean score of occupational fatigue was high among the nurses of female Post-cardiac Care Unit (post-CCU) (58.12</span></span><span dir="RTL" style="letter-spacing:-.1pt;"><span style="color:black;">&plusmn;</span></span><span style="letter-spacing:-.1pt;"><span style="color:black;">12.24) and moderate among the nurses of other hospital wards. The results of t-test indicated significantly lower mean scores of sleep latency, taking sleeping medications, and acute fatigue in nurses with a second job, compared to nurses with a single job (<em>P</em><0.05).</span></span><br> <strong><span style="background:#2D7F8F;"><span style="color:white;">&nbsp;Conclusion: </span></span></strong>&nbsp;<span style="color:black;">Sleep problems and occupational fatigue in nurses of the female Post-CCU and nursing stations were higher and lower than the nurses working in the other hospital wards, respectively. Furthermore, the second job variable was found to be important and influential.</span></span></span></p> Hospital, Nurse, Occupational fatigue, Sleep quality 336 345 http://journal.zums.ac.ir/browse.php?a_code=A-10-5389-1&slc_lang=en&sid=1 Mohammad Amin Rashidi rashidi.mohammadamin74@gmail.com 5200319475328460088807 5200319475328460088807 No Dept. of Occupational Health Engineering, School of Medical Sciences, Tarbiat Modares University, Tehran, Iran Mohammad Reza Piran Aghl mohammadreza_piran@yahoo.com 5200319475328460088808 5200319475328460088808 No Dept. of Occupational Health Engineering, School of Medical Sciences, Tarbiat Modares University, Tehran, Iran Omran Ahmadi ahmadiomran6912@gmail.com 5200319475328460088809 5200319475328460088809 No Dept. of Occupational Health Engineering, School of Medical Sciences, Tarbiat Modares University, Tehran, Iran Abdolhossein Pournajaf poornajaf@yahoo.com 5200319475328460088810 5200319475328460088810 No Dept. of Occupational Health Engineering, School of Public Health, Ilam University of Medical Sciences, Ilam, Iran Majid Seififard majidseifyfard74@gmail.com 5200319475328460088811 5200319475328460088811 No Dept. of Nursing, Faculty of Nursing and Midwifery, Ilam University of Medical Sciences, Ilam, Iran Mehrdad Kazemi kazemi.mehrdad1362@gmail.com 5200319475328460088812 5200319475328460088812 No Dept. of Occupational Health Engineering, School of Public Health, Ilam University of Medical Sciences, Ilam, Iran Masoud Pournajaf mpoor3402@gmail.com 5200319475328460088813 5200319475328460088813 No HSE Attendant of the Synthetic Cycle Power Plant of Nowshahr, Nowshahr, Iran Meghdad Kazemi kazemy.meghdad@gmail.com 5200319475328460088814 5200319475328460088814 Yes Dept. of Occupational Health Engineering, School of Public Health, Ilam University of Medical Sciences, Ilam, Iran
