Purpose: The purpose of this study was to compare the working status and Standard Shiftwork Index (SSI) between night shift-fixed nurses and rotating shift nurses. Methods: Participants were 367 nurses working as registered nurses at 7 different medical institutions. The data were collected from August 8, 2016 to September 30, 2016. Results: Night shift fixed nurses were more satisfied with work schedule than rotating shift nurses. Rotating shift nurses reported higher SSI scores, such as chronic fatigue, musculoskeletal problems, than night shift fixed nurses. In SSI's sub-items, rotating shift nurses reported higher scores, such as the amount of sleep, feeling well after sleep, heartburn or stomach-ache and heartbeat irregularities, than night shift fixed nurses. Conclusion: The results indicated that night shift fixed system might be an effective method to improve nurses' work satisfaction. It is necessary to figure out any suitable night shift fixed system based on the characteristics of each nursing organization. The SSI might be an useful tool to measure the nurses' satisfaction in reference to their work shift.

Background: The aim of this study was to investigate the burden experienced by nursing personnel working irregular shifts in Greece and to conduct the first test of a Greek version of the Standard Shiftwork Index (SSI). Methods: A cross-sectional survey was carried out. The SSI was completed by 365 nurses and nursing assistants working shifts, including nights. Results: Female nursing personnel and those suffering from a chronic disease were most affected by working rotating shifts as they had elevated scores on the majority of the SSI scales, such as sleep, chronic fatigue, digestive and cardiovascular problems, general health questionnaire, cognitive and somatic anxiety, shift time satisfaction, engagement and disengagement strategies, languidity, flexibility, and neurotisicm. Nurses with longer working experience and those with family responsibilities also scored higher on some of the SSI scales, such as the sleep, shift time satisfaction, social and domestic disruption, disengagement strategies, morningness, and languidity scales. Conclusion: Shiftwork affects female nurses, those with chronic disease, older age, and domestic responsibilities more severely. Therefore management should take these factors into account when designing work schedules to alleviate the burden caused by shiftwork.

연구배경 : 본 연구는 순환제 교대근무가 전반적인 수면양상과 주간의 졸리움에 미치는 영향을 평가하고, 주간의 졸리움과 성격요인 사이의 상호관련성에 대해 알아보고자 시도되었다. 방법 : 20-30대 순환제 교대근무 간호사 41명과 대조군 39명을 대상으로 Beck 우울척도(BDI), 상태특성불안 척도(STAI), 고려대학교 병원 수면장애 클리닉 수면력 검사지, Epworth 졸리움 척도(ESS), 성인용 성격요인 검사(16PF) 등을 실시하였다. 결과 : 교대근무로 박탈된 수면시간은 평균 64.26분 ${\pm}\;14.54$이고, 수면에 어려움을 겪는 빈도($1.24\;{\pm}\;1.17$일/주 vs $0.67\;{\pm}\;1.31$ 일/주, p < 0.05), 잠들기 어려울 때 수면까지 걸리는 시간($103.05\;{\pm}\;73.48$ 분 vs $70.00\;{\pm}\;60.08$, p < 0.05), 불면증이 있을 때 취하는 수면시간($204.25\;{\pm}\;79.90$ 분 vs $280.44\;{\pm}\;111.59$ 분, p < 0.001), 최근들어서의 기력의 변화($x^2\;=\;4.16$, p < 0.05), 수면에 대한 걱정($x^2\;=\;11.08$, p < 0.05), 낮잠자는 여부($x^2\;=\;4.98$, p < 0.05) 등의 문항에서 교대근무를 시행한 대상군과 대조군 사이에 유의한 차이를 보였다. 또한 Epworth 졸리움 척도의 결과도 순환제 교대근무자에서 $8.68\;{\pm}\;3.04$로 대조군의 경우인 $6.86\;{\pm}\;3.04$인 경우보다 유의하게 높았다(p < 0.01). 성격요인검사에서 자아강도 요인(C factor, $R^2\;=0.283$), 민감성 요인(I factor, $R^2\;=0.358$), 도덕성 요인(G factor $R^2\;=0.470$)이 주간에 느끼는 졸리움의 정도에 대해 유의한 설명량을 보였다(p < 0.001). 결론 : 순환제 교대근무 간호사들은 불면증, 수면부족등과 같이 여러가지 수면곤란을겪고 있으며, 이는 심한 불안감, 기력 및 집중력 저하의 원인이 되는 것으로 사료된다. 또한 주간의 졸리움도 순환제 교대근무자에서 유의하게 많이 겪고 있었다. 순환제 교대근무로 인해 겪는 주간의 졸리움의 정도를 예측하는 성격요인으로는 신경증적 행동의 속성인 정서적 불안정을 나타내는 낮은 자아강도 요인, 정서적으로 민감하고 의존적인 성격을 나타내는 높은 민감성 요인, 그리고, 직업에 만족하지 못하는 속성을 의미하는 낮은 도덕성 요인 등이 보여졌다.

The occurrence of the shift work disorder (SWD) in health-care workers (HCWs) employed in 24/7 hospital wards is a major concern through the world. In accordance with literature, SWD is the most frequent work-related disturb in HCWs working on shift schedules including night shift. In agreement with the Luxembourg Declaration on workplace health promotion (WHP) in the European Union, a WHP program has been developed in a large Hospital, involving both individual-oriented and organizational-oriented measures, with the aim to prevent the occurrence of SWD in nurses working on shifts including night shift. The objective assessment of rotating shift work risk and the excessive sleepiness were detected before and after the implementation of the WHP program, by using the Rotating Shiftwork-questionnaire and the Epworth Sleepiness Scale. The findings of this study showed the effectiveness of the implemented WHP program in minimizing the impact of shift work on workers' health and in preventing the misalignment between sleep-wake rhythm and shift working.

Background: In today's modern world, longer working hours, shift work, and working at night have become major causes of the disruption of our natural circadian rhythms. This study aimed to investigate the effects of the type of shift work (rotating vs. fixed day), duty period (on-duty vs. off-duty), and working period within each shift (nighttime vs. daytime) on the circadian rhythm characteristics of nurses who provide direct patient care. Methods: This cross-sectional study used a purposive sampling method. Cosinor analysis was applied to analyze the actigraphy data of nurses providing direct patient care for seven consecutive days. The linear mixed effects model was then used to determine any variances between shift type, duty period, and working period within each shift for the nurses. Results: The mesor value did not differ according to nurses' shift type, duty period, and working period within each shift. The amplitude was statistically higher in on-duty nurses and in daytime working hours. The acrophase was significantly delayed in nighttime working hours. As well as nurses in rotating shift had experience. Conclusion: Our findings revealed that the peak activity of nurses occurs significantly later at night while working and nurses working during nighttime hours may have a weaker or less distinct circadian rhythm. Thus, this study suggests that limits be placed on the number of rotating nighttime shifts for nurses.

In order to provide necessary information for better health of workers through understanding the actual status of the industries adopting shift systems. The data were gathered from a stratified random sample of 347 (0.5%) firms selected out of about 70,000 manufacturing industries throughout the nation in 1993. Stratification during sampling was by industrial group and number of workers. The major findings obtained from 288 firms surveyed completely were as follows : 1. About 20.2% of the 288 firms were adopting shift systems and shirtworkers accounted for about 25.1% of the total work force in 288 firms. 2. The bigger number of workers was, the higher the adopting rate of shift system was. 3. The rate of having welfare facilities such as dining room, commuting bus, washing facilities, and health care room etc. was higher in the industries adopting shift systems. 4. The major industrial groups adopting shift systems were the rubber a: plastic goods manufacturing industry (54.1 per 100 firms) and the textile manufacturing industry (44.8 per 100 firms). However, the proportion of shiftworkers was higher in the textile manufacturing industry (70.5 per 100 firms) and the electronics industry (57.9 per 100 frms). 5. The most predominant work schedule was the weekly rotating, semi-continuos 2-crew 2-shift system (47.5%). 6. In the industries adopting shift systems, shiftworkers had an adjusted average of 0.29 spells per 100 workers ($0.14{\sim}0.45$ in 95% C.I.) compared to 0.23 spells per 100 nonshift dayworkers ($0.15{\sim}0.31$ in 95% C.I.) for 1 month. 7. Also, in the industries adopting shift systems, the adjusted average annuel turn-over rate of shiftworkers was 13.07 per 100 workers ($12.03{\sim}14.12$ in 95% C.I.) compared to 10.18 per 100 nonshift dayworkers ($9.53{\sim}10.82$ in 95% C.I.).
