Colorectal cancer screening programmes conducted through gFOBT must be quality assured in terms of structures, execution and evaluation
Quality assurance of colon cancer screening programmes has to include all relevant steps of the program (“screening chain”). Prerequisites are defined structures of screening test delivery, organization of an adequate follow up combined with constant measurements of both quality of service provision and outcomes. Critical factors are test interpretation and in particular the follow up process in case of positive test results. In order to monitor these processes the instalment of quality indicators is of highest relevance.
