Chen Y, James JJ, Michalopoulou E, et al. - Via this retrospective study of data retrieved from consenting readers in the screening program in England (NHSBSP) where double reading is standard, researchers sought to examine if a test-set based assessment scheme (PERFORMS) utilized in a national breast screening program could aid in predicting real-life performance. With this aim, they investigated if there is any correlation between the number of cancers missed by mammography readers in real-life and the number of cancers missed in the PERFORMS test-set as well as examined the effect of real-life reading volumes on performance. A highly significant positive correlation was observed between the real-life and PERFORMS test-set missed cancer metrics amongst the 536 readers. Using a test-set based assessment scheme, real-life mammography reading performance could accurately be predicted, indicating its utility in identifying poor reader performance.
