How to Corporate Employee Wellness Programs Use Incentives to Save Money?

For three years a school district implemented a comprehensive worksite wellness strategy. This blog summarizes the research that shows how elevated health risks were reduced and medical costs lowered and is based entirely on peer-reviewed, scientific evidence.

The Worksite

For the three years prior to the implementation of a worksite wellness program, (between 2009 and 2011), the 3,269 employees of large school district located in the Rocky Mountains, experienced medical costs of between $11,000,000 and $13,000,000 per year. Equally sized employers in the Western U.S. experienced similar health care cost trends. During this time period, 60 percent of district employees had become overweight or obese, 61 percent had hypertension or prehypertension, 39 percent had high or borderline high cholesterol, and 5 percent had diabetes or pre-diabetes. The average age was 50. Approximately 15% of employees worked in manual occupations. The district health care bill was paid for by local taxes. The district was, and continues to be, fully insured with a retained-retention agreement which gives their medical plan the benefits a self-funded health plan; meaning that health care premium payments in excess of health care costs are returned to the district. Claims costs above $250,000 are reinsured by a stop loss policy. The combination of poor health behaviors, elevated health risks and increasing medical cost trends convinced the district to begin a comprehensive worksite wellness strategy.

The Corporate Employee Wellness Program

A full time worksite wellness program coordinator was hired and WellSteps LLC was hired as the worksite wellness vendor. The wellness program design was based on the premise that employee-related expenses such as absenteeism, presenteeism, and medical costs are greatly influenced by poor employee health. Poor health is the direct result of elevated health risks most of which are driven by poor lifestyle choices. Therefore, to impact employee-related expenses, wellness programming must focus on the root cause of poor health ─ unhealthy behaviors. The wellness program at the district was designed to help employees improve health behaviors and to make the overall work culture more supportive of good health practices. The program provided employees with the education, awareness, motivation, tools, strategies, supportive policies and social support needed to adopt and maintain healthy behaviors. This scientific approach to behavior change has been well-documented and is summarized by O’Donnell, 2013.

Before participating in the program, employees completed a self-reported Personal Health Assessment (PHA) after which they received individualized electronic feedback. Additionally, to assess health-promoting policies and environments, the onsite wellness program coordinator and some committee members completed a health culture audit called “The Checklist to Change.” Data from the PHA and Checklist to Change were summarized and discussed by a WellSteps account manager with the onsite Wellness coordinator.

Figure 1 shows the components that were used to design the overall wellness strategy. The program incorporated administrative planning, baseline data evaluation, culture change and communication strategy, biometric screening, behavior change campaigns, and more. Four campaigns lasting four to eight weeks were offered each year. Campaigns are designed to improve health behaviors and build self-efficacy by reducing the behavior change process to manageable weekly tasks. Detailed explanations of each aspect of the wellness program used by the district can be seen at wellsteps.com.

Health and wellness Incentives

Two types of incentives were used to promote program participation. Those who completed behavior change campaigns were entered into a drawing for gift cards to local retail stores. A second, more robust incentive was benefits-based. These were changed each year and are described in Table 1.

Results from the Corporate Employee Wellness Program

The WellSteps model suggests that improved health behaviors will lead to lower health risks and subsequent reductions in medical costs. Peer-reviewed scientific papers documenting the effectiveness of the model at this district have been previously published here and here. Table 2 shows improvements in nutrition, physical activity, tobacco, and alcohol use among those with the unhealthiest baseline behaviors. These behaviors improved from baseline and continued improving through at least two full years. Table 3 shows changes in biometric health risks. There was consistent risk reduction among those who had the unhealthiest numbers at baseline.

Do Wellness Programs Save Money?

Figure 2 below shows the predicted medical costs had the district followed the same cost trends of comparable worksites. This prediction provides a good estimate of what the cost trend would have been in the absence of a wellness program. But the district did not experience the predicted trend of comparable worksites. Rather, district medical costs peaked in 2011, then decreased each year through the end of the evaluation period (2014). The district medical costs in 2014 ($11,390,481) were lower than the costs in 2009 ($11,590,407) basically showing a zero trend across the six-year evaluation period.

Individual wellness program participation data were then combined with individual medical cost data to allow for comparison of the medical costs between wellness program participants and non-participants. Six years of medical cost data were evaluated including the three years prior to wellness program implementation. The “pre-program” cost data was used to statistically remove pre-existing differences in cost between participants and non-participants. During the three-years prior, program non-participants had slightly higher medical costs ($3,414 vs $3,308). No differences existed in age or sex between participants and non-participants. Post-implementation, there was a dramatic difference in the cost of medical care between wellness program participants and non-participants in 2012 and 2013, and to a lesser extent in 2014 (Figure 3).

From 2012 to 2014, the program participants cost the district $5,025,138 less in medical costs than non-participants. It is highly likely that this cost savings is primarily due to the impact of the comprehensive wellness program. The cost of providing the wellness program during the same three year period was $1,412,736. Thus, the benefit to cost ratio for the program was 3.56 ($5,025,138/$1,412,736). During this study there were no changes in the district’s health plan design.

Short Comings

Despite the improvements in health behaviors and risks, BMI did not improve. But while the U.S. population as a whole grew heavier during the three years under evaluation, the participants in this study did not. So, while there was no loss of weight, participants did not gain weight either.

Takeaways

Randomized clinical trials (RCTs) are an evaluation gold standard and none of the studies on which this report is based were (RCTs). However, it is currently illegal to randomize employees to a non-wellness program condition. This criticism aside, we ask: If the worksite wellness program was not responsible for these documented improvements in health behaviors, health risks, and medical costs, than what was? These findings show the published research that answers the question, do wellness programs save money?  A worksite with a zero medical cost trend over a six-year period is extremely rare. This paper provides ample evidence to show that worksite wellness strategies can be effective at promoting health and reducing employee medical expenses.

Note: the health care cost findings in this blog were previously published in the journal Preventive Medicine
