During the last decade, workplace wellness programs have become commonplace in corporate America. The majority of US employers with 50 or more employees now offer the programs. A 2010 meta-analysis that was favorable to workplace wellness programs, published in Health Affairs, provided support for their uptake. This meta-analysis, plus a well-publicized “success” story from Safeway, coalesced into the so-called Safeway Amendment in the Affordable Care Act (ACA). That provision allows employers to tie a substantial and increasing share of employee insurance premiums to health status/behaviors, and subsidizes such program implementation by smaller employers. The assumption was that improved employee health would reduce the employer burden of health care costs.
Subsequently, however, Safeway’s story has been discredited. And the lead author of the 2010 meta-analysis, Harvard School of Public Health Professor Katherine Baicker, has cautioned on several occasions that more research is needed to draw any definitive conclusions. Now, more than four years into the ACA, we conclude that these programs increase, rather than decrease employer spending on health care with no net health benefit. The programs also cause overutilization of screening and check-ups in generally healthy working age adult populations, put undue stress on employees, and incentivize unhealthy forms of weight-loss.
Through a review of the research literature and primary sources, we have found that wellness programs produce a return-on-investment (ROI) of less than 1-to-1 savings to cost. This blog post will consider the results of two compelling study designs — population-based wellness-sensitive medical event analysis, and randomized controlled trials (RCTs). Then it will look at the popular, although weaker, participant vs. non-participant study design. (It is beyond the scope of this posting to question non-peer-reviewed vendor savings claims that do not use any recognized study design, though those claims are commonplace.)Read the rest of this entry »
