Harvard Professor Katherine Baicker is arguably most acclaimed health policy researcher at arguably the most acclaimed (and not even arguably, the best-endowed) school of public health in the country. Her seminal account of the effect of Medicaid coverage on utilization and health status is a classic. As luck would have it, in 2008 Oregon used a lottery to ration available Medicaid slots. A lottery controls for motivation and as such eliminates participant-non-participant bias, since everyone who enters the lottery wants to participate. That meant only one major variable was in play, which was enrollment in Medicaid or not.
Chance favors the well-prepared, and Professor Baicker jumped on this research windfall. She found that providing Medicaid–and thereby facilitating access to basic preventive medical care–for the previously uninsured did not improve physical health status, but did increase diagnoses and utilization. Because of the soundness of the methodology, the conclusion were unassailable – more access to medical care does not improve outcomes or optimize utilization, which is a proxy for spending. (We ourselves reached a similar conclusion based on a similar analysis on North Carolina Medicaid’s medical home model.)
Yet Professor Baicker herself used exactly the opposite methodology to reach the exact opposite conclusion for workplace wellness. And that’s where the identity crisis begins.
She and two colleagues published a meta-analysis in 2010 of participant-vs-non-participant workplace wellness programs. Somehow—despite her affinity for Oregon’s lottery control—she found this opposite methodology to be acceptable. She concluded that workplace wellness generated a very specific two significant-digit 3.27-to-1 ROI from health care claims reduction alone, with another 2.37-to-1 from absenteeism reduction. The title of the article–now celebrating its fifth anniversary as the only work by a well-credentialed author in a prestigious journal ever published in support of wellness ROI—was equally unambiguous: Workplace Wellness Can Generate Savings.
Dec 31 2014: Last year I claimed laziness and failed to write or send out my End of Year Issues email for the first time since I started in 2000. Perhaps it was the stress of being 50, or the fact that despite having 15,000 of my closest friends follow me on Twitter I cant seem to reach people on email, or people miss my Facebook posts. But this year I’ve been guilted back into it by altogether too many people asking me where it was?!
