Impact of risk mitigation strategies on non-fatal injuries in the construction sector in qatar: a retrospective analysis.

PURPOSE

The construction sector has the highest risk of fatal and non-fatal injuries worldwide. This study examined the impact of risk mitigation strategies implemented in Qatar's construction sector between 2013 and 2021 on non-fatal injuries.

METHODS

This study employed quantitative and qualitative methods. Data on implemented strategies were gathered through a systematic website search and structured interviews with Safety and Occupational Health officers. Retrospective injury data were obtained from Hamad Trauma Center medical records. Systematic website search identified key legislation and guidelines. Interview transcripts were analyzed using qualitative content analysis. Injury data were categorized into pre- and post-implementation data. Differences were assessed using means, standard deviations, percentages, effect sizes, and confidence intervals.

RESULTS

Eight safety legislation/policies and guidelines were issued. Interview analysis identified technical, behavioral, and organizational measures as key themes in risk mitigation strategies. Comparing pre- and post-implementation data, non-fatal injury incidence (effect size (ES): 0.21, 95% CI 0.19-0.28) and severity (ES: 0.32, 95% CI 0.25-0.40) were reduced. Hospital and ICU stays were shorter post-implementation (ES: 0.2, 95% CI 0.12-0.27 and 0.014, 95% CI 0.010-0.021). Injury reductions were observed across major affected areas, except for the chest and skin. Non-fatal injuries remained more common among general laborers (ES: - 0.26, 95% CI - 0.34, 0.18) and those wearing protective devices (ES; - 0.1, CI - 0.12, - 0.07).

CONCLUSION

Implemented risk mitigation strategies collectively reduced non-fatal injury incidence and severity and improved outcomes in the construction sector. Future research should explore observed trends through prospective studies and job hazard analysis.
