Assessing capacity for hereditary cancer risk assessment in metro Chicago.

Abstract

307 Background: Since 2005, the United States Preventive Services Task Force (USPSTF) recommends that primary care (PC) clinicians identify and refer adults with a high-risk cancer family history to cancer genetic services (CGS), yet hereditary cancer risk assessment (HCRA) continues to be underutilized in PC. A population-based approach to HCRA in PC settings can expand access to cancer prevention and early detection to vulnerable populations and reduce disparities in cancer outcomes. The Chicago Cancer Screening and Testing Access Coalition (CCSTAC) is developing strategies to integrate HCRA in PC settings. We conducted an environmental scan to assess current capacity to deliver 1) HRCA in Federally Qualified Health Centers (FQHCs) and 2) follow-up CGS for high risk patients. Methods: In 2023, we administered two surveys to assess HCRA practices in Metro Chicago. We invited 22 FQHCs to complete a 21-item survey of current practices, readiness to implement, and barriers to HCRA. We also invited 21 CGS sites to complete a 25-item survey to understand staffing, utilization, referral patterns, and barriers to access. Surveys were administered electronically via Qualtrics. We conducted a descriptive analysis of survey data. Results: Twenty FQHCs (91%) completed the survey on HCRA in PC; 85% reported familiarity with USPSTF guidelines for HCRA. The majority (75%) reported no plans to implement HCRA. Clinic workflow, paucity of follow-up resources, cost, lack of provider knowledge, and absence of HCRA as a mandatory performance measure were cited as the most significant barriers to implementation. Genetic counselors (GCs) from 19 CGS hospital-based sites (90%) completed the survey on availability of genetic services. CGS were most often located in a cancer center (47%); no CGS were located in PC. Most referrals originated from oncology, surgery, or gastroenterology, with the lowest rate of referrals from community-based PC. Nearly half of CGS clinics (47%) reported capacity for at least a small increase in patient volume. Wait-time at the majority of CGS clinics was less than a month. GCs cited patient logistics (e.g. transportation, time off work), lack of referral information from providers, and systemic racism as significant barriers in patient access to CGS. Conclusions: After almost 20 years of evidence-based guidelines, use of HCRA is still very limited in the community-based PC setting. Our findings point to a need to bridge the gap between hospital-based CGS and FQHCs to ensure patients in vulnerable communities have access to guideline-concordant cancer prevention and screening strategies. Based on these findings, CCSTAC is designing strategies to integrate HCRA in primary care at FQHCs focused on provider education, well-designed clinic workflows, connections with existing CGS, and advocacy to align UDS and HEDIS measures with USPSTF guidelines.
