Problem Statement:
Precise localisation is essential for excision of non-palpable breast lesions. Hook wire guided localization is the standard technique used, but it is associated with workflow inefficiencies. Wires must be placed by the radiologist and excised by the surgeon on the same day, thereby creating interdepartmental scheduling inflexibility, decreased productivity and delays in definitive patient care. This study examines the cross-disciplinary workflow changes using an alternative localisation method with a small, nonradioactive magnetic seed (Magseed) which can be placed days prior to surgery.
Methods:
This study is a retrospective review of Magseed and Hook wire guided breast localisation and outsourced radiology service in a regional non-tertiary hospital from May 2018 to July 2021. Data from radiology and surgery departments, included scheduling details, procedure times, and volume of cases were compared between Magseeds and wire localisation.
Results:
Sixty-eight Magseeds were placed in fifty-nine patients and sixty-three hook wires were placed in sixty-three patients. There was an average of nine days between Magseed placement and surgery whereas wires had been placed on the same day of the surgery. The average radiology procedure time for Magseed insertion was seven minutes, whereas an average of twenty minutes was required for wire insertion. A maximum of five cases of Magseed were booked a day, while only two cases of wire-guided excision were able to be booked due to scheduling inflexibility. Immediate intraoperative confirmation of Magseed using Endomag probe resulted in an average of 46 minutes perioperative time reduction compared with standard pathological post-operative specimen confirmation following hook wire-guided excision.
Conclusion:
Magseed localisation in non-tertiary hospitals improves cross-disciplinary efficiencies by reducing scheduling delays and procedure times. Increased surgical volume with the use of Magseeds has the potential for more patients to receive timely definitive care. Further research is necessary to determine if these workflow improvements impact clinical outcomes.

CROSS-DISCIPLINARY WORKFLOW IMPROVEMENTS WITH MAGSEED LOCALISATION FOR NON-PALPABLE BREAST LESIONS IN NON-TERTIARY HOSPITALS IN QUEENSLAND

We are pleased to welcome you to the Australasian International Breast Congress (AIBC) held jointly with the [Australasian Society for Breast Disease (ASBD)](https://www.asbd.org.au/),[6th World Congress on Controversies in Breast Cancer (CoBrCa)](http://cobrca.org/) and [Breast Surgeons of Australia and New Zealand (BreastSurgANZ) in Brisbane, Australia](https://www.breastsurganz.org/).

The Joint Congress will continue the tradition of directly addressing key issues facing clinicians in their daily practice, including medical oncology, surgery, radiation oncology, breast imaging, pathology, reconstruction, allied health and survivorship issues.

We are delighted to have assembled a stellar international and national faculty and thank all those who have agreed to participate and those who have submitted abstracts. We trust that the program is an informative and enjoyable experience.

Thank you for joining us.
