Abstract

PURPOSE
The purpose of this study is to analyze medical audit of screening digital mammography at a tertiary hospital and to review changes of medical audit according to newly revised standard.
MATERIALS AND METHODS
We analyzed 7764 asymptomatic women who underwent screening mammogram at our hospital from January, 2013 to December, 2014. The family or past history of breast, gynecologic and other cancers was reviewed retrospectively. Analysis 1 defined category 3 as positive result and analysis 2 defined category 3 as negative.
RESULTS
The overall cancer detection rate was 4.6 per 1000 cases. The cancer detection rate in patients with non-gynecological and non-thyroid cancer (n = 391, 51.2) was the highest compared to patients with family history of breast cancer (n = 691, 1.4), or gynecological cancer (n = 311, 12.9). In analysis 1, positive predictive value 1 decreased 1.3% (6.0% vs. 7.3%) and recall rate increased 1.3% (7.3% vs. 6.0%) compared with analysis 2. The results were appropriate for newly revised target.
CONCLUSION
The results of screening digital mammography in the tertiary medical institution showed excellent results even if category 3 was regarded as positive. In addition, screening tests for secondary cancer are needed in the tertiary hospital.
