Abstract

Abstract Background Pre-scheduled appointments can increase attendance in breast cancer screening programmes compared to ‘open invitations’ but relatively few randomized controlled trials exist. We investigated the effect of a pre-scheduled appointment on uptake in the Flemish population-based mammography screening programme. Methods Between September and December 2022, a total of 4798 women were randomly assigned to receive either a pre-scheduled appointment or open invitation. The difference in attendance was compared with Poisson regression analysis for the primary endpoint (attendance ≤92 days after date of invitation), yielding relative risks (RRs). This was done separately for three groups: women invited to a mobile unit and a history of nonattendance (group M-NA); women invited to a hospital-based unit and a history of nonattendance (group HB-NA); women invited to a hospital-based unit and a history of irregular attendance (group HB-IA). There were no women invited to a mobile unit and a history of irregular attendance. Results The RRs in favour of the pre-scheduled appointment were 2.3 [95% confidence interval (CI) 1.80–2.88], 1.8 (95% CI 1.07–2.97) and 1.8 (95% CI 1.43–2.39), for groups M-NA, HB-NA and HB-IA, respectively. We found no statistically significant difference between the various RRs. The respective absolute gains in attendance between pre-scheduled appointment and open invitation were 8.3%, 4.4% and 15.8%. Conclusions Sending an invitation with a pre-scheduled appointment is an effective tool to increase screening attendance in both mobile and hospital-based screening units. The pre-scheduled appointment is associated with a considerable absolute gain in attendance which varies depending on the screening history.
