Title: Cost-effectiveness of strategies to enhance mammography use.
Journal: Effective clinical practice : ECP
Date: 2000 Sep-Oct
Abstract: OBJECTIVE: To estimate the cost-effectiveness of three strategies to increase breast cancer screening with mammography (reminder postcard, reminder telephone call, and motivational telephone call). DESIGN: Cost accounting for each strategy followed by cost-effectiveness analysis. DATA SOURCE FOR EFFECTIVENESS: Randomized trial of three strategies conducted at Group Health Cooperative of Puget Sound (GHC). TARGET POPULATION: Women 50 to 79 years of age who were enrolled in GHC's breast cancer screening program who did not schedule screening mammography within 2 months after it was recommended by letter. PERSPECTIVE: Health plan. OUTCOME MEASURE: Marginal cost-effectiveness of each additional woman screened. RESULTS OF BASE-CASE ANALYSIS: Because of its high cost (about $26 per call) and intermediate effectiveness, the motivational call was the least cost-effective strategy. If it was assumed that 50% of the women who scheduled mammography after receiving the reminder postcard would have scheduled mammography within 10 months even without it, marginal cost-effectiveness for the postcard among all women was $22 per woman screened versus $92 for the reminder call. Among women with no previous mammography, the marginal cost-effectiveness for the postcard was $70 versus $100 for the reminder call. RESULTS OF SENSITIVITY ANALYSIS: Among women with no previous mammography, the choice between the reminder postcard and the reminder call was sensitive to assumptions about the percentage of women expected to receive mammography in the absence of other promotional strategies. CONCLUSIONS: A simple reminder postcard is the most cost-effective way to increase mammography. Choices about how to promote mammography will ultimately depend on plan values and willingness to invest in promotional strategies that increase participation at higher unit costs.
