9029 Background: Addressing guideline concordant FP and TPP with cancer is challenging, especially for OT. SIM, a well-known education tool, has not been traditionally used to teach these topics. As part of the hematology/oncology fellowship curriculum, we designed a SIM applying LSP to bridge this educational gap. Methods: Applying LSP of contrasting cases, elaboration, feedback, generation and just-in-time telling, chief OTs and faculty designed a SIM with 3 clinical scenarios (CS) and 3 standardized pts (SP): FP for a female pt hospitalized for acute lymphoblastic leukemia tx, FP for a male pt in clinic for germ cell tumor tx, and breast cancer tx for a pregnant pt in 2 nd trimester. OT received written educational materials (WEM) and attended a lecture 1 week and 1 day pre SIM, respectively. OT were split into 2 groups; 1 started in the FP CS and 1 in the TPP CS, and then they switched. To reduce cognitive overload, each OT participated in 1 of 2 FP CS: half in the female FP CS and half in the male. Faculty and chiefs led debriefing sessions after all CS. The FP debrief ended with a special “learner as a teacher” part, where OT who attended the female CS taught those from the male CS about their topic and vice versa. The SIM concluded with "take-home" points. Pre (after having WEM) and post SIM anonymous surveys and verbal feedback assessed OT comfort, perceptions, and knowledge. Results: A 3 hour SIM with 14 OT and 5 faculty was completed successfully. SIM ended with all OT verbally sharing a learning point and positive feedback. All OT filled pre and post SIM surveys. Pre SIM, 17% reported having prior FP education, and 42% had prior TPP education. However, only 8% and 25% felt adequately prepared for FP and TPP discussions, respectively. Post SIM survey showed major improvement in comfort and knowledge about FP and TPP (see table 1). 75% of OT favored a combination of SIM and learning by teaching over other SIM formats. 83% supported having a TPP lecture before SIM. 100% reported satisfaction with FP and TPP SIM’s quality and wanted similar activities in the future. 92% were satisfied with the learner as a teacher tool. 100% felt education about FP and TPP with cancer should be part of fellowship training. Moral/cultural concerns were discussed as possible challenges in FP education. Conclusions: The application of LSP through SIM significantly increased OTs’ comfort discussing FP and TPP with cancer, and objectively enhanced their knowledge on these topics compared to after reading WEM. The SIM was largely perceived as a successful activity to educate about challenging topics and should become part of fellowship curriculum.

10588 Background: Detection of pathogenic germline variants (PGVs) has implications for cancer screening, prognostication, treatment selection, clinical trial enrollment and family testing. Published guidelines provide indications for PGV testing, determined by clinical and demographic factors, but these leave a significant number of cases missed by guideline-directed testing (incremental PGV). We have previously shown that 50% of patients with PVGs would not have been detected with guideline-based testing alone. In this project, we aimed to determine the feasibility and generalizability of this approach within a more racially/ethnically diverse cohort from a community cancer practice. Methods: We completed a prospective study of proactive germline genetic sequencing among patients with solid tumor malignancies at a community-based oncology practice in downtown Jacksonville, FL between June 2020, and September 2021. The patients were unselected for cancer type, stage, family history, race/ethnicity, and age. PGVs identified using an 84-gene NGS platform were stratified by penetrance. National Comprehensive Cancer Networks (NCCN) guidelines were used to determine incremental PGV rates. Results: 221 patients were enrolled, median age 63.0 years, 21.7% male. 56.6% of patients were white (non-Hispanic), 32.6% were black/African American, 5.4% were Hispanic. 39.8% of patients were commercially insured, 52.4% insured by Medicare/Medicaid and 2.7% uninsured. The cohort was comprised predominantly of breast cancer (61.5%), lung cancer (10.4%) and colon cancer (7.2%) patients. A total of 27 PGVs were identified in 23 patients. We found no significant difference in the rate of PGVs based on race/ethnicity. The overall rate of variants of uncertain significance (VUS) was numerically higher in black/African American patients (61.1%) compared with other ancestry (45%). 13 of 23 (56.5%) patients with detected PGVs did not meet NCCN guidelines for germline genetic screening (incremental PGVs). Conclusions: This prospective study found that universal multi-gene panel testing among patients from a racially/ethnically diverse cohort from a community cancer practice was associated with an increased detection of heritable variants with treatment implications over the predicted yield of targeted testing based on guidelines. This study is the first to evaluate this approach in an exclusively community-based practice. Clinical trial information: NCT04456140.
