Objective: To use results on recall rates from a regional non-populationbased breast screening programme to inform practice in a planned national population-based programme. Methods: We analysed data on rates of recall for further assessment in 27,327 mammographic screening episodes in 2015-16 in the breast screening programme in the city of Tbilisi, Georgia. Screening was by twoview digital mammography with double reading in women aged 40-70, and further assessment took place at the same clinic and during the same visit as the initial screening mammogram. Results: Recall rates were 46% (3,573/7,824) in 2015 and 27% (5,276/19,503) in 2016. Cancer detection rates were 8 per thousand in 2015 and 3 per thousand in 2016. Rates of recall were higher in younger women than in older, whereas rates of cancer detection where higher in older women. Conclusions: The recall rates, while lower in 2016 than in 2015 are still too high to manage in a nationwide population programme. The use of samevisit assessment is likely to be contributing to this. The national programme should consider separate assessment clinics and carry out audit of recalls to date.
