Organisational safety climate and occupational accidents and injuries: an epidemiology-based systematic review.

It is widely accepted among practitioners and researchers that a good safety climate results in improved safety. However, there is a lack of systematic and detailed reviews summarising and evaluating the scientific evidence underpinning the relationship between safety climate and injuries and accidents in a company. The current research addresses this gap and studies the association of safety climate with accidents and injuries at work. Nine databases were searched for quantitative studies. After eligibility and quality selection, 17 peer-reviewed papers were analysed. Quality assessment was developed applying the Strengthening the Reporting of Observational Studies (STROBE) guidelines, together with 9 appraisal criteria from Berra and colleagues (2008), Downs and Black (1998) and the appraisal tool from the University of Cardiff Weightman, Mann, Sander, & Turley, (2004). An evaluation summary statement was then constructed analysing the strength of the evidence provided by each study. Although 15 of the 17 studies included in this review provided full or partial support for the association of safety culture with accidents/injuries at work, scientific evidence is still unclear on the causal relationship between these two variables. Research is needed, especially longitudinal and intervention studies, to demonstrate in detail this association, which has been widely accepted in the area of occupational health and safety.
