Abstract PO5-05-04: Advancing Treatment and Management of Patients with HR+/HER2- Breast Cancer: Findings from a Quality Improvement Initiative

Abstract

Abstract Background: With the advent of novel oral oncolytics, the cancer care delivery model for HR+/HER2- breast cancer (BC) is evolving, shifting the responsibility for medication adherence and monitoring and managing of side effects to patients and their caregivers. In this quality improvement (QI) initiative, we aimed to uncover and address gaps in patient and provider education, risk reduction, adverse event management, and shared decision-making in order to improve outcomes for HR+/HER2+ patients on oral oncolytics. Methods: From 9/2022 to 12/2022, 54 HCPs who treat breast cancer and 111 HR+/HER2- BC patients from 4 US community oncology clinics completed surveys assessing attitudes, values, and challenges related to practice patterns, education, and therapy adherence in HR+/HER2- BC. HCPs participated in audit-feedback sessions to reflect on survey results and their own practice, and developed action plans to improve care, which were implemented in subsequent collaborative patient-provider learning sessions. Results: Top reported HCP challenges in HR+/HER2- BC care include providing patient-centered supportive care measures (32%), patient adherence/lack of follow up (22%), and individualizing treatment plans (17%). Additionally, 43% of providers reported that improved collaboration across interprofessional teams would most improve care. Top reported patient challenges include worry about and/or difficulty managing side effects from treatment (26%), difficulty scheduling visits with many different HCPs/following up (24%), and difficulty communicating with healthcare teams (16%). In surveys, 28% of patients reported frequently or very frequently missing/skipping doses of oral breast cancer medication. Top reasons for missing/skipping doses included forgetting or not having it nearby (36%), cost (21%), and side effects (20%). To address the top challenges identified in baseline surveys, HCPs developed and implemented action plans, such as improving the identification of patients at high risk of recurrence, establishing patient-provider educational sessions, increasing the use of patient navigators, incorporating oral adherence toolkits, and educating patients and staff about available supportive care resources. After implementation of patient-provider collaborative education sessions at community clinics, patients reporting high levels of knowledge about BC treatment options and communicating side effects/symptoms increased from 27% to 57%, and 37% to 77%, respectively. At 60-day follow-up, 58% of patients reported taking a more active role in treatment decision-making, and 52% reported setting reminders/alarms/using apps to remember to take medication on time. Conclusions: Patient adherence to oral oncolytic medications remains a challenge in BC treatment. This quality improvement initiative uncovered underlying barriers to effective treatment management of HR+/HER2- breast cancer patients on oral oncolytics. Action plans and educational resources were developed and implemented to address identified barriers and optimize treatment management for HR+/HER2- BC. These methods and findings represent key opportunities for improvement that can be implemented in community oncology practices to improve adherence to oral oncolytics and overall HR+/HER2- breast cancer care.
