Effect of mammography outreach in women veterans.

We undertook this study to test whether progressive intervention would increase the use of mammography. In 1995, we randomly assigned into 2 groups 717 underserved women veterans in the Veterans Affairs Palo Alto (California) Health Care System (VAPAHCS) who earned less than $22,000 a year. The women were sent an informational letter and brochure explaining why mammography is needed and how often. The letter further requested that if the woman was due for a screening mammogram or if a lump or other recent change in her breast had occurred, that she call for scheduling of a free mammogram and a visit to the breast clinic. Women in group I (n = 351) received no further intervention. Women in group II (n = 366) received a follow-up phone call by a breast care nurse if they had not responded within 45 days of the informational mailing. The nurse talked to each woman about her particular needs, explained to her that the screening mammogram would be provided free of charge, and discussed transportation arrangements to the mammography facility. A total of 17 women in group I had mammograms versus 100 in group II during the same time period. We conclude that the additional intervention of a phone call by a breast care nurse increased use by more than 5-fold, which reached significance (P < .01).
