Education program for general practitioners on breast and cervical cancer screening: a randomized trial. PRE.SA.GF Collaborative Group.

This study was aimed at evaluating the effects of an education program for general practitioners on their prescribing behaviour for cervical and breast cancer screening tests, and assessing the feasibility of general practitioners participation in screening programs. All three cytology laboratories and 19 of the 20 radiologists in one administrative region ("Haute-Savoie") in France agreed to participate. The 278 general practices in this region were randomly assigned to either the intervention group (a one-day seminar on screening for breast cancer and cervical cancer) or the control group (n for both = 139). The prescriptions of tests for the following year were noted from the laboratories' and radiologists' records. No significant differences were observed between the intervention group and the control group for the number of mammographies prescribed with a mean of 19.3 and 15.2 per practice, respectively. However, significantly more mammographies were prescribed in women aged over 50 by the intervention group (p = 0.038). Inversely, fewer smear tests were prescribed in the intervention group (mean per practice: 40.5 and 46.1, respectively). A significantly higher number of practices in the intervention group did not prescribe any smear tests (p = 0.007). This study suggests that it is possible to influence general practitioners' participation in screening programs, but that the messages should be carefully presented, since negative effects are possible.
