Return on investment of workplace-based prevention interventions: a systematic review

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.

Important collaborative conditions for successful economic outcomes of work disability management: A mixed methods multiple case study

BACKGROUND

Work disability management (WDM) interventions have usually focused on a single factor and its impact on outcomes such as employee health or work disability costs. Research on company-level WDM activities and their economic impact is scarce.

OBJECTIVE

The aim of this study was to explain the change in company-level work disability costs and their relation to WDM practices, and to identify the mechanisms of impact through which the successful economic outcome emerged.

METHODS

The study design was a convergent mixed methods design with a multiple case study. The data from 14 business units concerned business context, personnel, investments in and processes of WDM, and the costs of work disability in 2010-2013. The data were constructed into case descriptions which were analysed using qualitative comparative analysis. The economic analysis was carried out from the employers' perspective.

RESULTS

Five business units gained net benefits of approximately 1.5-2.5% of the payroll sum from their investments in WDM. These benefits were characterised by a combination of four strategic processes: i) dismantling barriers to co-operation, ii) improving the visibility of the strategic goals of work ability management in everyday practice, iii) WDM actions targeting the company's main work disability risks, and iv) the facilitation of multi-actor co-operation through co-ordination and flow of information.

CONCLUSION

Strategic processes to support the effectiveness of WDM were found. When aiming for economic success in work disability management, in addition to measuring and managing disability costs, it is also essential to maintain collaborative operations in everyday practice.

The economic impact of workplace physical activity interventions in Europe: a systematic review of available evidence

Purpose

There is growing interest in the economic impact of workplace physical activity interventions, but the evidence is still lacking — especially in Europe. Although, some evidence on the return on investment (ROI) is found in literature, the included studies may not be applicable to the Europe situation. Therefore, the objective of this study was to review current evidence on the economic impact of workplace physical activity interventions in European countries.

Design/methodology/approach

A systematic review on the economic impact of worksite health promotion programs aiming at increasing physical activity was conducted. Five electronic databases (MEDLINE (Ovid), MEDLINE (PubMed), EMBASE, NHS-EED and Emerald Insights) were searched for relevant studies published between 2000 and 2020.

Findings

A total of 953 abstracts were screened, and 28 were reviewed, 11 of which met all inclusion criteria. The studies varied substantially in sample size, intervention type, duration and frequency of follow-up measurements, valuation methods and assessed economic outcomes. There is inconclusive evidence for decreasing absenteeism, positive net benefit (NB) and positive ROI. No evidence was found to indicate an effect on self-assessed productivity or job satisfaction.

Originality/value

This study is the first try to take the different working conditions from Europe into consideration. The authors found that working conditions could have some impact on the valuation of absenteeism costs and thereof on the ROI. Further, this study provides insight into how to deploy effective and efficient workplace physical activity interventions, based on a standardized and validated methodology and program scope.

Work Productivity Losses and Associated Risk Factors Among University Employees in the CAMMPUS Wellness Program

OBJECTIVE

The aim of this study was to comprehensively measure work productivity losses of employees enrolled in a pharmacist-led wellness program and assess associated risk factors.

METHODS

The study sample was employees at least 18 years old with a Framingham Risk Score (FRS) at least 10% or 1+ medication-modifiable cardiovascular risk factor (196 participants at baseline and 166 at 12-month endpoint). Total work hour losses (WHL) were measured using the Valuation of Lost Productivity questionnaire. The factors anticipated to be associated with WHL included work habits, FRS, body mass index (BMI), physical activity, and health-related quality of life (HRQoL).

RESULTS

Sedentary work habits, higher BMI, and lower HRQoL were significantly associated with more WHL for males. Among females, only a lower HRQoL was significantly associated with more WHL.

CONCLUSIONS

Our findings help identify employees at greater risk for WHL and provide insights on how workplace wellness programs can be modified.
