This study examines radiologist reading policies with breast screening
; specifically it estimates the incremental cost-effectiveness of non-
consensus double reading compared to single reading. Cost-effectivenes
s is measured in terms of the cost per cancer detected. Data on effect
iveness from a study of 255 000 women attending five Scottish centres,
over the period 1992-1996, are combined with cost data from a recent
study of eight UK screening centres. The incremental costs per cancer
detected by double reading compared to single reading range from pound
1162 (US$1859) to pound 2221 (US$3554) depending on assumptions with
respect to screening and assessment costs.
