Evaluation of a worksite mammography program

We implemented a one-year program to promote mammography for employees at one campus of a state university system; a second campus served as a comparison site. Measurement cohorts, who were surveyed immediately before and after the intervention, had been randomly selected at each site; all of the subjects had insurance coverage that included mammographic screening. The intervention consisted of print media, on-site workshops, and incentive drawings. Results indicated that mammography rates increased significantly at both sites, for both those 40-49 years of age and for those > or = 50 years of age. The rate increases for the 40- to 49-year-old age group at the intervention and control sites were 17.6% and 13.6%, respectively, and, for the > or = 50-year-old age group, 11.9% and 6.3%. However, the differential changes in rates between the sites were not significant for either age category. The intervention was perceived positively by the intervention site cohort, and participation in the various components was encouraging. We present suggestions for future research on this topic.
