発表テーマ Physical load on the low back in hospital nurses working day and night shifts
発表者 Itoko Tobita, Masaru Nakaseko, Thomas Laeubli
Abstract Musculoskeletal disorders(MSDs) are commonly reported among the nursing staff in hospitals. The aim of this study was to evaluate physical load on the low back in 23 hospital nurses working day and night shifts. The findings of surface electromyography of the left and right sides of the lumber region of the erector spinae muscle and 3-dimensional accelerator and gyroscope findings of postural movements were recorded and averaged to discriminate between static and dynamic musculoskeletal strain at work. The findings were recorded3 min in 3 modes of postural movements(static work, work while standing, and walking), atrain on the low back was much higher during static work than work that during standing work and walking. Muscle activity from low back muscles, in which 5% and 10%RVCμV level were significantly dominant. The average activity did not differ significantly on the right and left side back muscles. However, relaxed muscle activity with less then 5%RVCμV and excessive strenuous activity with more than 100% RVCμV were significantly different on the 2 sides. Muscle activity between day shift and night shift showed a significant difference with respect to average muscle activity, relaxed muscle activity, and excessive strenuous activity.

テーマ Work-life balance among hospital nurses in Japan:an evaluation of the current status of the family support system
発表者 Masami Nakayama, Itoko Tobita, Hiroe Takahashi, Masaru Nakaseko
Abstract To reduce or remove sources of workplace stress and to improve the work-life balance (WLB)of Japanese working at hospitals, this study aimed to investigate the current status of the family support system for child-care in Japan and the working and living conditions of these nurses. A questionnaire was distributed to 475 nurses working at a hospital in Japan; 347(73.7%) of them responded, including 38 nurses who utilized the system (support group) and 299 who did not (non-support group). The results indicated that organizational changes after the introduction of the system were observed in the ‘private life’, ‘understanding of the system’, and ’word environment’ between groups(p<0.05). Significant differences were observed between groups regarding their perception of work, with one characterizing it as ‘intensive’, ’very busy’(p<0.01), ’too much required’(p<0.05). The family lives and social activities of nurses were influenced by the number of working hours, indicating that reducing or eliminating overtime is important for the achievement of a better work-life balance. The results also showed that organizational management had limited impact on the system. Thus, to manage WLB more effectively, organizational goals should be aligned with individual ones, and scope of organizational support should be enhanced.

テーマ Phychophysiological workload of hospital nurses in day and night shifts
発表者 Chiemi Hayashi, Itoko Tobita, Christian Mueller, Masaru Nakaseko, Keiko Ebihara, Rie Yamada
Abstract This study examines psycho physiological workload of 33 hospital nurses in day and night shifts using objective measures of heart rate and blood pressure(systolic blood pressure: SBP, diastolic blood pressure: DBP), and self-rated subjective feeling (fatigue, irritability, and busyness). Date were collected from each subject every 7 working sessions; subjects were asked to provide data with respect to a short period during their work. Self-rated fatigue and irritability significantly increased over working sessions, and statistically significant differences between day and night shift nurses were observed. Heart rate significantly differed across working sessions and was Higher in day-shift nurses than night-shift ones. SBP and DBP significantly differed across working sessions but no between nurses in differences shift. Subjective fatigue was closely related to irritability and busy nurses. Both SBP and DBP had weak correlations with heart rate. This finding suggests than heart rate is significantly influenced by circadian rhythm and that subjective evaluation is influenced by work-load. In night-shift nurses, a low heart rate showed an antagonistic effect against physiological function to work activity. Level of blood pressure had a positive trend depending on working activity. Further analysis is needed to explore the relationships among subjective feelings, heart rate, and blood pressure.
