OBJECTIVE: To audit the @entity0 screening mammograms performed in a general hospital and to assess the variation in medical practice in the diagnostic process. MATERIAL AND METHODS: A review was carried out on the screening mammograms performed between 1 May 2010 and 30 April 2011, with clinical follow up for two years, and a comparison with the published standards. RESULTS: Of the 3,878 @entity1 examined, 368 (9.48%) were called back to complete the study (97 [16.1%] in the initial screening and 271 [8.2%] in revisions). Forty three biopsies (1.1%) were indicated, of which 24 were diagnosed with @entity5 . The positive predictive value ( @entity2286 ) in screening studies (PPV1) was 6.52%. For the recommended biopsy (PPV2) it was 55%, with a sensitivity of 100%, a specificity of 91% and a @entity5 detection rate of 6.1/1,000. There were no false negatives. Twenty @entity5 were invasive; with no axillary lymph node infiltration was observed 15 of them. In 6 cases, the size of the @entity5 was less than or equal to 10mm, and in 17 it was less than 15mm. There were a higher percentage of new appointments by two radiologists (12% and 17.2% versus 7.3%) (P<.001). In 217 cases (58.96%; P<.001) only one radiologist indicated new appointments. Of this group, 73% were discharged in the first visit, compared to 47.6% in the non-discrepant group (P<.001). Four of the @entity5 were detected in these 217 @entity1 . CONCLUSIONS: The observed results are adjusted to the reference values. The discordant data are the new appointments rate, both in the initial screening and in the review, with a significant variation depending on the radiology reader.
