Background: Despite guidelines recommending germline genetic testing (GT) and genetic counseling for individuals with pancreatic ductal adenocarcinoma (PDAC), referrals remain suboptimal. This can have negative implications on treatment, particularly for patients with actionable mutations. This project aims to compare the referral rate to genetic services of MD Anderson Cancer Center at Cooper pre- and post-implementation of an electronic health record (EHR) physician best practice advisory (BPA) recommending a cancer genetics referral order for PDAC patients. Methods: Medical records, cancer genetics referrals (CGR), and germline and somatic testing results were retrospectively reviewed for patients with a PDAC diagnosis in 2019-2020, and prospectively for those diagnosed after BPA implementation from October 2021 through May 2022. The primary outcome was the rate of CGR, and the secondary outcomes were genetic counseling encounters and GT completion. Descriptive statistics were used for analysis. Results: Prior to BPA initiation, CGR were offered to 44 (24.3%) of 181 eligible patients with 39 (88.6%) of those accepting CGR. Germline testing represented 90.9% (30 patients) of the GT performed in the pre-BPA group. Post-BPA, CGR were offered to 23 (51.1%) of 45 eligible patients with 20 (86.95%) of those accepting CGR. Germline testing represented 100% (13 patients) of the GT performed in the post-BPA group. Conclusions: Only 24.3% of patients diagnosed with PDAC between 2019-2020 were referred to cancer genetics, showing that even after updated NCCN guidelines in 2018 the CGR rate remained low. Following BPA implementation, CGR increased to 51.1% over 8 months for newly diagnosed patients. Germline testing increased by 10%. These preliminary results show that implementing a physician BPA can increase CGR and germline GT, which could have positive implications on treatment. Limitations include a lack of a standardized referral process for the pre-BPA group and a limited timeframe to obtain GT for the post-BPA group.
