Breast cancer screening: comparison of radiologists' performance in a self-assessment scheme and in actual breast screening

The PERFORMS self-assessment scheme is used by the UK Breast Screening Programme as an educational tool. From this scheme a radiologist can gain insight into their own sensitivity, specificity, feature and cancer detection performance. Such data may, however, be questionable if they are not well related to the radiologist's performance in actual breast screening. Consequently, data from the scheme were compared with those from actual breast screening performance. Some correlations were found in performance, this indicates that continued use of the scheme is important to identify any areas of individual difficulty.
