Fatigue experienced by physicians may not only endanger their own health but may also affect the safety of patients. Such fatigue may be associated with the work environment and personal factors such as work-family conflict (WFC). This study aimed to determine the association between WFC and prolonged fatigue among Japanese married male physicians.
Physicians who graduated from a Japanese medical school answered a mailed anonymous self-report questionnaire. For assessment of WFC and prolonged fatigue, the Japanese versions of the WFC scale and the Checklist of Individual Strength questionnaire (CIS) were used. Prolonged fatigue was defined as the upper quartile of total CIS scores. The WFC scale comprises six dimensions. Total scores were divided into tertiles: low, intermediate, and high levels of WFC. A multiple logistic regression analysis was performed to examine the association between WFC and prolonged fatigue.
A total of 540 male physicians answered the questionnaire, and the data of 444 married male physicians were analyzed. The data were then adjusted for age and work condition factors. Prolonged fatigue was significantly associated with high strain-based work interference with family (WIF; corrected odds ratio, 5.56; 95% confidence interval, 2.55-12.1), intermediate strain-based WIF (2.53, 1.25-5.10), high time-based family interference with work (FIW; 1.92, 1.08-3.40), and there was a weak association with high strain-based FIW (1.93, 0.98-3.83).
Employers should take measures to improve working conditions in hospitals, and give physicians the opportunity to learn how to cope with WFC. These measures could ultimately help prevent prolonged fatigue.
医生所经历的疲劳不仅会危害自身健康，还可能影响患者安全。这种疲劳可能与工作环境以及工作-家庭冲突（WFC）等个人因素有关。本研究旨在确定日本已婚男性医师的 WFC 与长时间疲劳之间的关系。
毕业于日本医学院的医师通过邮寄匿名自填问卷作答。采用日本版 WFC 量表和个体力量检查表（CIS）评估 WFC 和长时间疲劳。长时间疲劳定义为 CIS 总分的上四分位数。WFC 量表包含六个维度。总得分分为三分位：WFC 低度、中度和高度。采用多变量逻辑回归分析检验 WFC 与长时间疲劳之间的关系。
共有 540 名男性医师回答了问卷，其中 444 名已婚男性医师的数据可用于分析。将数据进一步调整为年龄和工作条件因素。长时间疲劳与高强度工作对家庭的影响（WIF；校正比值比，5.56；95%置信区间，2.55-12.1）、中度 WIF（2.53，1.25-5.10）、高强度时间型家庭对工作的干扰（FIW；1.92，1.08-3.40）显著相关，且与高强度 FIW 存在弱相关（1.93，0.98-3.83）。
雇主应采取措施改善医院的工作条件，并为医师提供学习应对 WFC 的机会。这些措施最终可能有助于预防长时间疲劳。
