Most active recruitment strategies for breast cancer screening programs examined in this review were more effective than no intervention. Combinations of effective interventions can have an important effect. Some costly strategies, as a home visit and a letter of invitation to multiple screening examinations plus educational material, were not effective. Further reviews comparing the effective interventions and studies that include cost-effectiveness, women's satisfaction and equity issues are needed.
The effect of patient and provider reminders on mammography and Papanicolaou smear screening in a large health maintenance organization.
We evaluated the effectiveness of 2 reminder interventions to increase the use of screening mammograms and Papanicolaou (Pap) smears among female members of a large health maintenance organization.
                Seven thousand seventy-seven female health maintenance organization members (aged 50-74 years with no prior mammogram in the previous 30 months or aged 20-64 years with no prior Pap smear in the previous 36 months) were randomized to receive one of the following: a letter inviting them to make an appointment for a mammogram or a Pap smear; in addition to the letter, a reminder manually placed in the patient's medical chart alerting providers of that member's need for screening; or their usual care.
                Compared with women who did not receive the reminder letter, women who did receive the letter were more likely to obtain mammograms (16.0% vs 25.5%, respectively; P < .001) or Pap smears (9.1% vs 19.5%, respectively; P < .001) in the 6 months following their entry into the study. Compared with women who received only the reminder letter, women who received a reminder letter and had a reminder placed in their medical chart were more likely to obtain mammograms (26.5% vs 30.9%, respectively; P = .02) and marginally more likely to receive Pap smears (19.5% vs 22.8%, respectively; P = .04).
                We recommend the use of patient reminder letters as a first step in a mammography or Pap smear screening outreach program. Further research is needed to evaluate a cost-effective provider reminder system and additional outreach strategies directed to women who do not use health care services.
