Suppose one day you sit in front of your work computer, click on a link supplied by your employer, and set about the task of answering a hundred or more highly intrusive health questions. Setting aside the issue of financial penalties or rewards for doing the survey, you would trust that the instrument itself, called a health risk appraisal (HRA), would actually have a sound scientific basis, especially since its ultimate goal is to give you purportedly accurate health guidance.
Unfortunately, your trust in the validity of the tool would be quite misplaced.
HRAs are an essential screening tool in workplace wellness programs despite the fact that no body of evidence clearly demonstrates either their fiscal or clinical value and that no health services research has determined which HRA is the optimal tool. Indeed, a recent review of HRAs concluded that they increase spending, not reduce it, and that no one has any idea whatsoever whether taking an HRA has anything to do with the delivery of health value.
By masking essential methodological truths about HRAs, wellness vendors have essentially hustled their employer clients into believing that HRAs, which frequently ask clinical questions best left to primary care clinicians or restate platitudes (gosh, I didn’t know it’s safer to drive while not under the influence), are both probative and predictive of a person’s health future. This is just simply wrong.
