How the PERFORMS Scheme Works

Each year a number of difficult and challenging screening cases are sent to us from several UK breast screening centres. These cases are anonymised so that they contain no patient identifiable information and then a number of expert screening radiologists review these cases judging their difficulty, suitability for the scheme and giving their opinions about various factors including the mammographic appearances.

After registering with the scheme, participants take part by reading the set of cases and reporting their various decisions about each case. 

Having read the set of cases, participants receive immediate graphical feedback from the reporting software concerning how their decisions agree with those of an expert panel of radiologists and also on how well they identified early and difficult signs of abnormalities.

Once everyone in the UK has taken part then all participants receive detailed and anonymous data such as shown here:
