Objective: To evaluate the disease management program implemented by the City of Knoxville in terms of its effects on employee biometric and absence outcomes.

Methodology: Administrative and biometric data were collected from 2008-2011 on City of Knoxville employees. Those eligible for disease management self-selected participation, and the two groups were compared statistically in terms of year-to-year changes in biometric measures and in absence hours.

Results: Descriptive analysis revealed statistical differences in the participant and nonparticipant groups at baseline. A difference-in-difference analysis of changes in biometric and absence data showed no statistically significant differences between participants and nonparticipants with the exception of diastolic blood pressure, although that outcome was clinically trivial. The analysis of administrative data showed no statistical reduction in absence when comparing the participant and nonparticipant groups (p = 0.58).

Conclusion: Selection bias, inaccurate data collection, and confounding factors prohibit broader attribution of evaluation findings to the general population. Improved evaluation design, including improved case-control matching to minimize confounding and bias and improved data collection to assure accuracy, would better serve future evaluations of the myHealth Program. Inherent variation in data related to absence, make administrative data analysis less useful. Adding productivity questions to an employee health risk assessment may be a better method to measure absence variation as a primary outcome.
