This study aims to compare workers' income before and after an occupational injury, with regard to return to work and job retention, over a period of 5 years.
This study was designed as a longitudinal study.
The Panel Study of Workers' Compensation Insurance (PSWCI) survey targeted workers involved in industrial accidents for which medical care was terminated in the year 2012.
The panel study was conducted on a final sample of 2000 workers who were selected proportionally by region (nine regions) after priority assignment by disability rating (six levels). A total of 1458 workers were finally included in this study.
This study used data from the first to fifth PSWCI. To identify the effect on income after occupational injury considering return to work and job retention, we used the generalised estimating equation.
In regard to workers' return to work, the OR that income after an occupational injury would be higher than that before an occupational injury was 3.17 (2.41-4.17) for those who returned to original work and 2.32 (1.81-2.97) for those re-employed as compared with who did not return to work and 1.27 (1.07-1.15) for those who retained their job as compared with those who did not. The ORs were 2.91 (2.26-3.75) for those who were re-employed and retained jobs and 2.96 (2.15-4.08) for those who returned to original work and did not retain jobs as compared with those who did not return to work and did not retain jobs.
It is important for accident victims to retain their jobs to maintain their economic status.
本研究旨在比较职业伤害前后工人的收入，关注其在 5 年内重返工作岗位和保留工作的情况。
本研究设计为纵向研究。
工人赔偿保险计划（PSWCI）调查针对的是在 2012 年医疗结束的工业事故中受伤的工人。
该面板研究对按地区（9 个地区）按残疾等级（6 个等级）优先分配后按比例选择的最终样本 2000 名工人进行了研究。最终共有 1458 名工人纳入本研究。
本研究使用了来自第一到第五次 PSWCI 的数据。为了确定职业伤害后收入的影响，同时考虑到重返工作岗位和保留工作，我们使用了广义估计方程。
就工人重返工作岗位而言，与未重返工作岗位的工人相比，职业伤害后收入高于职业伤害前收入的 OR 为 3.17（2.41-4.17），对于返回原工作的工人和重新就业的工人 OR 为 2.32（1.81-2.97）；与未保留工作的工人相比，保留工作的工人 OR 为 1.27（1.07-1.15）。与未重返工作岗位且未保留工作的工人相比，重新就业且保留工作的工人的 OR 为 2.91（2.26-3.75），返回原工作且未保留工作的工人的 OR 为 2.96（2.15-4.08）。
对于事故受害者来说，保留工作以维持其经济地位非常重要。
