Keeping oncologists current with CDK4/6 inhibitors in HR+ breast cancer: The impact of online education.

Abstract

e13044 Background: CDK4/6 inhibitors have revolutionized the care of patients with hormone receptor positive (HR+), HER2-negative breast cancer, improving survival outcomes. There are multiple CDK4/6 inhibitors available that differ in their pharmacologic features, reported outcomes, therapeutic indications, and adverse event profiles. Education is needed to empower clinicians to optimally use these agents in practice and personalize breast cancer treatment. The goal of this educational initiative was to increase the knowledge, competence, and confidence of oncologists regarding clinical trial data and factors for selection of CDK4/6 inhibitor. Methods: This educational approach included a 30-minute online video discussion among 3 expert faculty, synchronized with slides to support the discussion. Educational effectiveness was assessed with repeated paired pre/post assessment in which learners served as their own controls. A chi-square test assessed differences from pre- to post-assessment. P values < .05 are statistically significant. Effect size was calculated using Cramer’s V test by determining the strength of the association between CME and the outcomes (V = .16-.26 is considerable and V > .26 is extensive). The activity launched 11/25/2019 and data are reported through 2/4/2020. Results: A total of 889 learners, including 513 physician learners, participated in the activity from 11/2019 through 2/2020. Participation in the education resulted in significant improvements in knowledge among oncologists (n = 81; p < .001; V = 0.16). On average, the proportion of learners who responded correctly to knowledge-based questions about CDK4/6 inhibitors increased from 51% at the pre-assessment to 67% at the post-assessment. Moreover, 41% of oncologists had a measurable positive change in confidence in their ability to incorporate CDK4/6 inhibitors into the treatment of HR+, HER2- advanced breast cancer. Significant improvements in knowledge were observed in the following areas: The clinical trial safety and efficacy data evaluating CDK4/6 inhibitors in the management of patients with HR+/HER2-negative breast cancer (32% vs. 51%, p < .05, V = 0.19). The potential role of patient- and tumor- specific prognostic factors in selection of individual CDK4/6 inhibitors (56% vs. 72%, p < .05, V = 0.17). Conclusions: This CME-certified online discussion resulted in statistically significant gains in oncologists’ knowledge and improved confidence surrounding the personalization of CDK4/6 inhibitor therapy in HR+/HER2- breast cancer.
