“…A major limitation of these studies is that working hours were elicited via self-report. Additionally, researchers measured working hours on a daily 3 , 6 , 7) or weekly basis 8 - 13) and monthly overtime 4 , 5 , 14) for various time frames, i.e., the previous week 12) , past month 5 , 8 , 13) , past 3 months 5 , 12) , and past year 13) , using a single question 3 - 11) , 14) . All these factors may influence the association between working hours and disease risk.…”

Objective: Working long hours is a potential health hazard. Although self-reporting of working hours in various time frames has been used in epidemiologic studies, its validity is unclear. The objective of this study was to examine the validity and reproducibility of self-reported working hours among Japanese male employees. Methods: The participants were 164 male employees of four large-scale companies in Japan. For validity, the Spearman correlation between self-reported working hours in the second survey and the working hours recorded by the company was calculated for the following four time frames: daily working hours, monthly overtime working hours in the last month, average overtime working hours in the last 3 months, and the frequency of long working months (≥45 h/month) within the last 12 months. For reproducibility, the intraclass correlation between the first (September 2013) and second surveys (December 2013) was calculated for each of the four time frames. Results: The Spearman correlations between self-reported working hours and those based on company records were 0.74, 0.81, 0.85, and 0.89 for daily, monthly, 3-monthly, and yearly time periods, respectively. The intraclass correlations for self-reported working hours between the two questionnaire surveys were 0.63, 0.66, 0.73, and 0.87 for the respective time frames. Conclusions: The results of the present study among Japanese male employees suggest that the validity of self-reported working hours is high for all four time frames, whereas the reproducibility is moderate to high.

“…Education is a purposive and planned learning process (Jeong et al, 2013). Campion (2015) definitely explained continuing education as a planned education activity for people returning to formal schools' education system, including non-traditional students in the USA and those being interested in adult education.…”

The development of medical technology has largely enhanced physicians' professional responsibilities. Besides, the emergence of consumer rights, patients' awakening of human right awareness, and the intervention of insurance have healthcare quality and physicians' professional abilities gradually become the focus of health policies. The importance of continuing medical education is therefore highlighted. With nonequivalent pretest posttest control group design, two hospitals in Hubei Province are studied. One is proceeded continuing medical education, while the other maintains the original situation without continuing medical education. The experimental study is preceded for half a year. The research results show that 1.continuing medical education would affect job stress, 2.continuing medical education would influence sleep quality, 3.job stress presents significantly negative effects on sleeping time in sleep quality, and 4.job stress shows remarkably negative effects on quality level in sleep quality. According to the results, suggestions are proposed, expecting to enhance healthcare staff's physiological and psychological health, promote job safety and performance, reduce medical incidents, and enhance healthcare service quality.

“…In a case-control study that targeted patients visiting emergency rooms in Korea, the odds ratio of CCVDs was 1.73 (95% CI=1.03-2.90) for those whose average number of weekly working hours was 48.1-52 hr, as compared to those whose number of weekly working hours was 40.1-48 hr during the past 3 months. The odds ratio of those whose average number of weekly working hours was over 52 hr was the highest, at 3.46 (95% CI=2.38-5.03) (22). …”

The purpose of this study was to discuss the history of, and concerns regarding, the newly amended criteria of occupational cerebrovascular or cardiovascular diseases (CCVDs). Since the early 1990s, CCVDs have been the second most common occupational disease, despite fluctuations in their criteria. The first issue was the deletion of cerebral hemorrhage on duty as a recognized occupational disease in 2008. The second issue was the obscurity regarding definitions of an acute stressful event (within 24 hr before disease occurrence), short-term overwork (within 1 week), and chronic overwork (for 3 or more months). In this amendment, chronic overwork was defined as work exceeding 60 hr per week. If the average number of weekly working hours does not exceed 60 hr, night work, physical or psychological workload, or other risk factors should be considered for the recognition of occupational CCVDs. However, these newly amended criteria still have a few limitations, considering that there is research evidence for the occurrence of disease in those working fewer than 60 hr per week, and other risk factors, particularly night work, are underestimated in these criteria. Thus, we suggest that these concerns be actively considered during future amendment and approval processes.Graphical Abstract
