Abstract PS9-56: High compliance with choosing wisely breast procedures at a safety net hospital

Abstract

Abstract The Choosing Wisely campaign has emerged recently in setting guidelines for surgical procedures of low utility and cost-ineffectiveness. Hospitals caring for underserved medical populations represent a unique opportunity to assess for quality of care and adherence to these guidelines. The Choosing Wisely campaign for breast surgery has highlighted: avoiding surgical re-excision for invasive cancer close to margins of excised breast tissue, avoiding double mastectomy in patients who have a single breast with cancer, avoidance of axillary lymph node dissection in women undergoing lumpectomy with limited nodal disease, and avoiding sentinel lymph node biopsy in patients ≥ 70 years of age with early stage breast cancer. Recent studies have shown variable adherence to these recommendations. In order to evaluate cost-effective surgery at our hospital serving a poorer patient population, we retrospectively analyzed patients who underwent surgery for breast cancer from 2015-2020. A total of 231 patients were identified. There were no patients who underwent re-excision for close margins of invasive cancer. Only 0.9% of patients (2/231) received contralateral mastectomy and only 1.6% of eligible patients (3/191) received axillary lymph node dissection instead of sentinel lymph node biopsy. Although 77.7% of patients ≥ 70 years of age with stage 1 hormone positive breast cancer (14/18) received sentinel lymph node biopsy, there was a downward trend during 2015 to 2020 from 100% to 50% of eligible patients receiving sentinel lymph node biopsy. De-implementation of traditional surgical practices, deemed as low-value care, towards newer cost-effective guidelines are achievable even at community hospitals serving a low socioeconomic community while preserving patient outcome and avoiding overtreatment. By avoiding overtreatment, cost savings can be achieved which allow for social distributive justice amongst breast cancer patients by ensuring careful utilization of scarce health economic resources.
