Short‐term impact of a voluntary health intervention on overall vs. preventive healthcare consumption

Healthtrac Rewards is a US‐based, workplace wellness intervention promoting healthy behaviour through voluntary self‐reporting of participants' dietary habits, physical activity and medical concerns. Monthly financial incentives encourage either primary participation or secondary participation requiring additional interaction with Healthtrac personnel. Using data from 17 533 eligible employees, the purpose of the study was to determine whether Healthtrac participants consumed fewer healthcare services, as measured by 2004 medical claim costs or numbers of procedures, relative to non‐participants. High‐cost individuals tended to self‐select into the programme. Costs were 22–27% greater among participants after controlling for other factors. Participants consumed more preventive care, however, which was correlated with reduced future procedures. The secondary intervention was more effective than the primary intervention, suggesting a priority on increasing intensity of involvement vs. basic enrolment.
