Evidence and decision making in occupational safety and health (OSH)

To help make working environments safer, it can help to use evidence to inform guidelines, regulations and decision making. Researchers investigated the availability and use of evidence in decision making and recommend several next steps.
What is the issue?
Occupational accidents and fatalities are prevalent globally, but the past decade has seen these rates plateau in many high-income countries. Enhancing workplace conditions and making workplaces safer is essential to decrease the number of fatalities, injuries and cases of occupational diseases. One way to make working environments safer is by using evidence to inform guidelines, regulations and decision making. However, it is currently unclear how OSH decisions are informed and what role evidence plays in the process.
How are we helping?
RAND Europe was commissioned by the Lloyd’s Register Foundation, in partnership with the National Safety Council, to investigate the current role that evidence plays in OSH. We conducted a Rapid Evidence Assessment (REA) of the existing literature, completed stakeholder engagement activities (including surveys and interviews) and developed two conceptual models. These methods enabled us to answer four research questions:
- What types of evidence exist in OSH?
- Who is using the evidence in OSH and what for?
- How are OSH decisions informed and what role does evidence play in this process?
- Which agencies are involved in producing, translating and sharing evidence in OSH?
What did we find?
Our research highlighted that there is no single definition of ‘evidence’ in the OSH space and that there are multiple information and research sources used in OSH decision making. We found that many actors in the OSH evidence ecosystem are involved in the ‘life cycle of evidence’, referring to the production, synthesis, sharing and use of evidence at an operational and systems level.
During our research, we discovered four main factors that influence decisions and evidence use in decision making. These were:
- The legal basis and regulations
- The business case (e.g. staffing)
- Evidence: its existence, accessibility and relevance
An organisation’s size and global location can also impact these factors.
What can be done?
For evidence sharers, we recommend greater investment in knowledge translation to tailor evidence towards it’s intended audiences (for example, translating academic literature into infographics or videos for non-OSH-specialist audiences).
For workplaces, we recommend promoting a positive safety culture among all workers, including organisational leaders who should be educated about the benefits that a safer work environment can offer their organisation.
For researchers, we recommend the following:
- Conduct further research into how evidence is used/not used to implement specific change (for example, evaluations to understand the use and effects of shared/translated evidence in practice, including long-term follow-ups).
- Cost/benefit analyses of evidence-based practice are required to provide empirical evidence addressing perceptions that evidence-based practice is costly.
- Collecting data on organisation sizes would be beneficial when conducting future research about evidence utilisation in OSH, as we found this to be a key influence.
- Make greater efforts to include representation from low-and-middle-income countries (LMICs) in research.
- To tackle the delay between the emergence of safety issues and the provision of new evidence, horizon scanning for future potential issues could be beneficial for the rapid mobilisation of evidence when needed.
- Mapping evidence ecosystems for specific countries, sectors and topics of interest could help identify OSH issues that would benefit from further research or interventions.
