Abstract

Background: Occupational Safety and Health is an important public health topic. Many employers may regard health promotion or prevention initiatives as an additional cost with few benefits. The aim of this systematic review is to identify the studies conducted on the return on investment (ROI) of preventive health interventions conducted within workplaces, and to describe their designs, topics and calculation methods.

Methods: We searched PubMed, Web of Science, Science Direct, National Institute for Occupational Safety and Health, International Labour Organization and Occupational Safety and Health Administration from 2013 to 2021. We included studies that evaluated prevention interventions in the workplace setting and reported an economic outcome or company-related benefits. We report the findings according to PRISMA reporting guidelines.

Results: We included 141 articles reporting 138 interventions. Of them, 62 (44.9%) had an experimental design, 29 (21.0%) had a quasi-experimental design, 37 (26.8%) were observational studies and 10 (7.2%) were modelling studies. The interventions' objectives were mostly related to psychosocial risks (N = 42; 30.4%), absenteeism (N = 40; 29.0%), general health (N = 35; 25.4%), specific diseases (N = 31; 22.5%), nutrition (N = 24; 17.4%), sedentarism (N = 21; 15.2%) musculoskeletal disorders (N = 17; 12.3%) and accidents (N = 14; 10.1%). The ROI calculation was positive for 78 interventions (56.5%), negative for 12 (8.7%), neutral for 13 (9.4%) and undetermined for 35 (25.4%).

Conclusion: There were many different ROI calculations. Most studies have a positive result but randomized controlled trials have fewer positive results than other designs. It is important to conduct more high-quality studies so that results can inform employers and policy-makers.
