Facility Inreach Strategy to Promote Annual Mammography

摘要

The purpose of this study was to increase annual return rates for screening mammography among asymptomatic women 50 - 74 years. The study tested the effectiveness of a physician endorsed reminder letter relative to a standard mammography facility reminder letter and to no intervention. Six mammography facilities and 82 referring physicians participated. Physician participation rates ranged from 35-67% across facilities. Over the course of the 23 month recruitment period, 3,701 eligible women were approached and 1,971(53%) of those consented to participate. Of the 1,971 consenting women, 108 women subsequently had positive mammograms and were excluded from the study, leaving 1,863 subjects. Subjects were interviewed by phone regarding knowledge, attitudes, and behaviors related to mammography. Overall, 1,818 telephone interviews were completed. Primary outcome data were available for 1,562 subjects. Forty-eight percent of subjects in the physician endorsed group returned within the 8-week monitoring period, 47% in the standard facility group, and 28% in the control group; the overall difference among return rates was significant (p<0.0Ol). Bonferroni pairwise comparisons indicated there was no difference between the physician endorsed and standard facility groups. However, both of these groups had significantly higher return rates than the control group.
