It is always good to see researchers assessing issues related to workplace health and safety rather than relying on overseas data. Recently researchers from the Australian Catholic University and St Vincent’s Hospital in Melbourne looked into “measuring the effectiveness of workplace health management programs” . The research adds to our understanding of these programs but the relevance to occupational health and safety (OHS) is limited.
The researchers,
Occupational health and safety (OHS) policy makers are keen on making decisions based on evidence. But evidence seems hard to get, for many reasons.
Some people, including those in workplace relations and OHS, often fill the evidence gap with “anecdotal evidence”. Frequently people being interviewed are asked for evidence to substantiate their claims and respond that “anecdotally” there is a problem yet there is no sample size for this evidence, there is no clarity or definition of the incident or issue – it is simply “what I heard” or “what I’ve been told”. Using anecdotal evidence is okay as long as its inherent uncertainty is acknowledged and it is not used as a basis for substantial change.
