Workplace wellness program and short-term changes in health care expenditures

Area of Science:

• Occupational Health
• Health Economics
• Preventive Medicine

Background:

• Workplace wellness programs are prevalent, aiming to lower employer healthcare costs.
• The 'Be Fit' program previously demonstrated positive effects on weight, cholesterol, and blood pressure.

Purpose of the Study:

• To evaluate if participation in the 'Be Fit' workplace wellness program is associated with reduced health expenditures.
• To analyze healthcare claims data for program participants and matched controls.

Main Methods:

• Difference-in-differences analysis of claims data from 289 'Be Fit' participants and 194 matched controls.
• Comparison of health expenditure changes from the year prior to the year after program initiation.
• Analysis included adjustments for matching characteristics and outlier exclusion.

Main Results:

• No significant reduction in healthcare expenditures was observed for participants compared to controls immediately following program participation.
• Adjusted quarterly health expenditures were only marginally lower for participants (-$236), with wide confidence intervals.
• No cost reductions were found when analyzing capped expenditures or specific disease categories (cardiovascular, diabetes).

Conclusions:

• Despite documented clinical improvements, the 'Be Fit' program did not show a significant association with reduced health expenditures within a 1-year follow-up period.
• Achieving cost reductions may necessitate longer observation periods or broader wellness program designs targeting multiple risk factors.
