Abstract

OBJECTIVES: To assess the efficacy of a minimal cost and involvement educational intervention in improving women's knowledge about screening mammography and to explore patient perceptions of the educational intervention. PARTICIPANTS AND METHODS: During the study period (March 10, 2005, to July 1, 2005), 1446 participants in the Mayo Mammography Health Study scheduled for a mammogram within 4 weeks at the Mayo Clinic in Rochester, Minn, were randomized to 2 study groups and malled surveys about mammograms. The 2 groups received separate surveys; both surveys contained knowledge-based questions about mammography, but the educational intervention group survey also contained qualitative questions that assessed the educational pamphlets. RESULTS: Of the 668 surveys returned (responders), 248 (34.4%) were from the control group, and 420 (58.3%) were from the intervention group. Approximately 80% of responders had had more than 7 prior mammograms. Significant increases in knowledge about mammography were found in the educational intervention compared with the control group on questions regarding age to begin screening mammography (67.9% vs 54.4%; P<.001), recommended frequency of mammograms (86.4% vs 75.4%; P<.001), overall reduction in mortality due to screening mammography (55.2% vs 8.9%; P<.001), and proportions of women who required follow-up mammograms (35.5% vs 14.9%; P<.001) or biopsy (59.5% vs 13.3%; P<.001). Qualitative data results indicated that most women who received the educational intervention found the pamphlets helpful and informative despite having had many previous mammograms. CONCLUSION: The results suggest that providing women scheduled for screening mammograms with physician-approved educational material before their appointment significantly increases knowledge about screening mammography, risks and benefits, and possible follow-up.
