Do Work-Related Lost-Time Injuries Sustained Early in Employment Predict Multiple Lost-Time Injuries Throughout Employment? 2019
The aim of this study was to identify a simple surrogate to predict the future risk of multiple lost-time injuries. Employees of an academic medical center who sustained 5,906 injuries were followed from 1994 to 2017 or 1,046,218 person years. The odds ratio of having three or more lost-time injuries during their entire duration of employment was 2.12 (95% confidence interval: 1.60 to 2.79) for employees having their first lost-time injury within the first 6 months of employment versus those injured after that, controlling for demographics and employment duration. For each increasing year before the first lost-time injury, the probability of having three or more lost-time injuries decreased by 13%. Employment duration before the first lost-time injury may be used to predict future lost-time injuries without detailed information of underlying risk factors.
