CALLER Re-operation Research Study

The ASBrS Research Committee has approved a prospective research study that builds on the 2015 ASBrS consensus conference termed CALLER (a collaborative attempt to lower lumpectomy re-operation rates). The aim of this research study is to investigate associations between surgeon processes of care and reoperation rates after initial lumpectomy for breast cancer. If a specific association is identified between a process of care or technique and fewer reoperations, then wider adoption of their use can potentially lower national reoperation rates. Multiple recent publications indicate wide variability of reoperation rates at the individual surgeon and the institutional level. The average national rate averages 20-25%.

We are requesting participation from Society members who currently use or want to begin using the ASBrS Mastery patient registry. The surgeon Mastery participant will agree to enter all consecutive applicable surgeries, with a minimum of 10 Lumpectomies during the 10 month period following initiation of the study.

This research project has funding from the Gundersen Medical Foundation and Dune Medical Devices Ltd. The study investigators have all disclosed no conflicts of interest. No industry representatives have participated in the study design. This study has been deemed not to be human subject research by the Gundersen Medical Foundation Human Subjects Committee/Institutional Review Board (Thomas Harter PhD) because the investigators will only have access to de-identified surgeon, patient and facility data.

Surgeon participants will receive a $500 incentive at the completion of the project. Participants will also be entered into two raffles- one for complimentary registration for the ASBrS general session at the annual meeting and one for membership dues for one year with ASBrS. This research project is limited to the first 50 participants who sign an attestation statement that they will enter consecutive lumpectomy patients and want to participate. Participating surgeons must have a missing data entry rate of <10% at the completion of the project. If more than 50 surgeon's desire study participation, then attempts to find further funding for their participation will be sought, but cannot be guaranteed.
