Despite much focus on the health impact of road traffic injury (RTI) on life, there is a lack of knowledge of the dynamic process of return to work following RTI and its related factors. The aim of this study was to identify longitudinal patterns of sickness absence (SA) following RTI, to examine the patterns' interplay with health-related quality of life (HRQoL) and to determine if there are differences, regarding the patterns and interplay, according to injury severity.
A register-based prospective cohort study.
Administrative data on RTI in Sweden from the Swedish Traffic Accident Data Acquisition System (STRADA) and Swedish Social Insurance data.
Individuals suffering an RTI (total n=4761) were identified in STRADA between 1 January 2007 and 31 December 2009. A total of 903 of these met the inclusion criteria for the current study and were included.
The primary outcome measure was SA following RTI. The secondary outcome measure was HRQoL.
Three distinct patterns of SA were identified; 'Stable', 'Quick decrease' and 'Gradual decrease'. The patterns differed in the number of initial SA days and the rate of reduction of SA days. After 3 years, all three patterns had almost the same level of SA. Higher injury severity and a higher number of SA days had a negative interplay with HRQoL. Participants who initially had a higher number of SA days were more likely to report a low HRQoL, indicating that people with a slower return to work are more vulnerable.
The study highlights the heterogeneity of return to work after an RTI. People with a more severe injury and slower pace of return to work seem to be more vulnerable with regards to HRQoL loss following RTI.
尽管人们非常关注道路交通伤害（RTI）对生命健康的影响，但对于 RTI 后重返工作岗位的动态过程及其相关因素，人们的了解还很有限。本研究旨在确定 RTI 后缺勤（SA）的纵向模式，研究这些模式与健康相关生活质量（HRQoL）的相互作用，并确定根据损伤严重程度，这些模式和相互作用是否存在差异。
一项基于登记的前瞻性队列研究。
来自瑞典道路交通事故数据采集系统（STRADA）和瑞典社会保险数据的瑞典 RTI 行政数据。
在 STRADA 中，2007 年 1 月 1 日至 2009 年 12 月 31 日期间确定了患有 RTI（总计 4761 人）的个体。其中共有 903 人符合当前研究的纳入标准，并被纳入研究。
主要结局测量是 RTI 后 SA。次要结局测量是 HRQoL。
确定了三种不同的 SA 模式，分别为“稳定”、“快速减少”和“逐渐减少”。这些模式在初始 SA 天数和 SA 天数减少的速度上有所不同。3 年后，所有三种模式的 SA 水平几乎相同。较高的损伤严重程度和较多的 SA 天数对 HRQoL 有负面影响。最初 SA 天数较多的参与者更有可能报告 HRQoL 较低，这表明恢复工作较慢的人更容易受到影响。
本研究强调了 RTI 后重返工作岗位的异质性。损伤严重程度较高且恢复工作速度较慢的人，在 RTI 后 HRQoL 丧失方面似乎更容易受到影响。
