抄録: Nurses work 23.4 hours of overtime on average per month, which is 13.2 hours longer than the monthly average for general workers. It has been reported that continuous work of more than 8 hours, which is the general length of working hours, increases fatigue and decreases attention and work efficiency in nurses. The purpose of Study I is to clarify the current status of the working environment and chronic fatigue for nurses in clinical care, and Study II is to test the association between working conditions during day shifts and chronic fatigue in nurses. Study I: An anonymous self-administered questionnaire was sent to 2,753 nurses working at 117 general hospitals with 300 or more beds located in eastern Japan, including Tokyo and 13 prefectures. Consent to participate in the survey was obtained in advance. The questionnaire included questions on basic attribute information, working environments, and signs of chronic fatigue. Out of 1,779 respondents, 1,676 females were included in the analysis. The results found that nurses were likely to have accumulated chronic fatigue if they were aged in twenties, worked 20 hours or more of overtime per month, and worked 3 shifts; conversely, nurses were less likely to have accumulated chronic fatigue if they were aged in their fifties, worked 10 hours or less of overtime per month, and worked only day shifts. Study II: The amount of physical activity and salivary amylase levels were measured for 3 days in 18 females out of 23 nurses working at General Hospital A. Also, the same questionnaire survey as used in Study I was conducted. Nurses were divided into the following 2 groups: outpatient nurses working only day shifts and ward nurses working 3 shifts. The results showed that the average number of steps per day was approximately 9,500, which was similar in the two groups. Salivary amylase levels did not differ significantly between the two groups, although they were lower in the evening than in the morning in the outpatient nurses and higher in the evening than in the morning in the ward nurses. Nurses work under conditions of accumulated fatigue, which leads to chronic fatigue unless they can sufficiently recover. Therefore, it is considered that systematic environmental control, in which the circumstances of nurses, such as their ages and work schedules, are taken into account, is necessary for reducing chronic fatigue amongst nurses. In addition, it is also important to identify task completion times and for nurses to have breaks in order to not accumulate fatigue.
