Annual cancer detection rates for a physician were grouped according to annual percentage recall rate. Next, a linear regression with bootstrap bias correction was performed to assess changes in cancer detection rate with each unit increase in the recall rate up to 20%, with the recall category of less than 7% taken as reference. First, they were separated into recall groups to assess cancer detection rate variation by the recall categories using rate ratios: less than 10%, 10% to less than 12%, 12% to less than 14%, and 14% or higher. The 75 annual recall rates were analyzed two ways. The percentages of minimally invasive and early-stage cancers were also calculated. Cancer detection rates were calculated from 984 screen-detected cancers identified in 188,959 total digital screening mammograms.

Medical outcome audit data collected in accordance with the Mammography Quality Standards Act from September 1, 2007, through August 31, 2012, were reviewed. The purpose of this study is to identify the optimal screening mammography recall rate range on the basis of cancer detection rates among breast imaging specialists at an academic institution.
