To determine the effectiveness of the University of Minnesota's worksite health promotion program in reducing health care expenditures during the first 2 years of the program; to investigate the program's effect on absenteeism; and to study the effect of specific disease- or lifestyle-management programs on both health care expenditures and absenteeism.
Health care expenditures and absenteeism of program participants were compared with those who were eligible but did not participate. Differences-in-differences regression equations with random effects were used to account for selection.
Participation in the general disease management program over 2 years was associated with significant reductions in expenditures, as was participation in programs for certain specific diseases. No consistently significant absenteeism or lifestyle management effects were found.
Although the program significantly reduced expenditures, it did not generate a positive return on investment.
