This study aimed to investigate the decline in quality of life (QOL) by examining changes in the employment status of workers who had completed medical treatment after an industrial accident.
This study utilized the Panel Study of Worker's Compensation Insurance cohort (published in October 2020) containing a sample survey of 3,294 occupationally injured workers who completed medical care in 2017. We divided this population into four groups according to changes in working status. A multivariate logistic regression model was utilized for evaluating QOL decline by adjusting for the basic characteristics and working environment at the time of accident. Subgroup analysis evaluated whether QOL decline differed according to disability grade and industry group.
The QOL decline in the "maintained employment," "employed to unemployed," "remained unemployed," and "unemployed to employed" groups were 15.3%, 28.1%, 20.2%, and 11.9%, respectively. The "maintained employment" group provided a reference. As a result of adjusting for the socioeconomic status and working environment, the odds ratios (ORs) of QOL decline for the "employed to unemployed" group and the "remained unemployed" group were 2.13 (95% confidence interval [CI], 1.51-3.01) and 1.47 (95% CI, 1.13-1.90), respectively. The "unemployed to employed" group had a non-significant OR of 0.76 (95% CI, 0.54-1.07).
This study revealed that continuous unemployment or unstable employment negatively affected industrially injured workers' QOL. Policy researchers and relevant ministries should further develop and improve "return to work" programs that could maintain decent employment avenues within the workers' compensation system.
本研究旨在通过调查工伤事故后完成治疗的工人就业状况的变化，来探究生活质量（QOL）的下降情况。
本研究使用了工伤保险队列的面板研究（于2020年10月发表），该研究对2017年完成医疗护理的3294名职业受伤工人进行了抽样调查。我们根据工作状态的变化将这一人群分为四组。采用多元逻辑回归模型，通过调整事故发生时的基本特征和工作环境来评估生活质量的下降情况。亚组分析评估了生活质量下降是否因残疾等级和行业组而异。
“保持就业”组、“就业转失业”组、“一直失业”组和“失业转就业”组的生活质量下降率分别为15.3%、28.1%、20.2%和11.9%。以“保持就业”组作为参照。在对社会经济地位和工作环境进行调整后，“就业转失业”组和“一直失业”组生活质量下降的优势比（OR）分别为2.13（95%置信区间[CI]，1.51 - 3.01）和1.47（95%CI，1.13 - 1.90）。“失业转就业”组的OR为0.76（95%CI，0.54 - 1.07），无统计学意义。
本研究表明，持续失业或就业不稳定会对工伤工人的生活质量产生负面影响。政策研究人员和相关部门应进一步制定和完善“重返工作岗位”计划，以便在工伤保险制度内维持体面的就业途径。
