Return to Work After Work-Related Injuries: A Systematic Review and Meta-Analysis of Incidence and Determinants

Background: Work-related injuries remain a considerable global burden; nevertheless, progress in occupational safety has been made in decreasing the time to return to work. This study aimed to assess the pooled incidence of Return to Work (RTW) among workers with occupational injuries and to identify the key factors influencing RTW outcomes. Methods: A systematic review was conducted by searching electronic databases (PubMed, Embase, Cochrane CENTRAL, Web of Science, and Scopus) to include eligible cohorts. Meta-analysis was undertaken using R software 4.5.1 with random-effects models, and heterogeneity was evaluated using the I² statistic. Results: This meta-analysis included 16 cohorts, with 4164 workers. A pooled analysis of 14 studies showed that 79% of workers successfully returned to their jobs after treatment for work-related injuries (95% CI: 0.67-0.88; p < 0.0001; I² = 97.5%). Meta-regression identified age as a significant moderator, with older workers showing a higher incidence of RTW. The mean time to RTW, pooled from 9 studies, was approximately 102 days, with no significant age association (p = 0.222). Regarding predictors, male workers had a significantly higher RTW rate than females (p < 0.0001). Married persons showed greater RTW rates (p < 0.0001). Also, workers with higher education levels were more likely to return to work (p = 0.0033). For injury type, lacerations were related to a greater RTW rate than crushing injuries. Conclusions: This meta-analysis underscored a significant overall return-to-work rate after work-related injuries, with age, sex, marital status, education level, and injury type affecting results. Advanced age and male sex were substantially correlated with increased return-to-work rates. These findings support the necessity for personalized rehabilitation programs and focused support to enhance work reintegration following occupational accidents.
