Effectiveness of timed and non-timed second appointments in improving uptake in breast cancer screening

Abstract

Objectives To estimate the effect on breast screening uptake of delayed, targeted, second timed appointments in women who did not take up an initial breast cancer screening appointment offer. Methods Non-attending women received a four-month delayed second timed appointment following non-response to the initial invitation and the normal open invitation sent to non-attenders. A comparison group was sent a four-month delayed additional open invitation. Results Response to the second timed appointments (percentage of re-invited women eventually attending in this episode) was 20%, corresponding to an estimated increase on total uptake of 6%. Response was highest in women who had previously attended screens. Response in the women offered an additional delayed open invitation was 7.5%, corresponding to an estimated 2.3% increase in overall uptake. Conclusions Second timed appointments were almost three times as effective as additional open invitation. They should be targeted at women most likely to attend. A randomized study of second timed appointments versus open invitations should be conducted.
