PARTICIPATION AND SCREENING PROGRAMS FOR COLORECTAL-CANCER - MORE WOULD BE BETTER

In clinical terms, a screening compliance rate of 100% may be deemed optimal in that the number of abnormalities detected is thereby maximized. This paper explores optimum compliance rates from the cost-effectiveness point of view by modelling the individual's decision to participate in the screening programme. Using data derived from contemporary colorectal screening trials, it assesses the compliance and cost effects of utilizing differing methods of screening invitation, and explores the incremental cost and benefits associated with compliance enhancement techniques. Given the estimated costs and benefits, attempts to attain higher levels of compliance would appear justifiable. © 1991.
