Background: Identifying the ~60 million unaffected persons in the US at risk for inherited cancers has the potential to reduce their cancer risk by up to 95%. However, most of these individuals are not identified currently because of multifactorial deficits in the 3-generation pedigree collection in clinical settings. Methods: Here we evaluated the impact InheRET, an online family history gathering and risk assessment reporting tool, has on facilitating National Comprehensive Cancer Network (NCCN) Guideline-compliant referrals for cancer genetic counseling/genetic evaluation by decreasing and/or removing the barriers of 1) in-clinic 3-generation family history collection, and 2) interpretation of the family and personal history in light of current NCCN Guidelines. Patients enrolled from primary care and specialty clinics completed the family health history from a web-enabled devices using InheRET Inherited Risk Evaluation Tool. Results: Of 255 enrolled patients, 78.4% completed the history form and, of these, 86.5% completed the feedback survey. 39.2% of primary care and 79.9% of specialty cancer genetics patients were found to be at increased risk. Patients with ≤ HS education ranked InheRET at 4.7/5.0 for Understandability and 3.33/5.0 for Ease of Use. Following the addition of clarifying directions, they ranked InheRET at 5.0 and 4.0, respectively. Pts. <60 ranked InheRET between 3.5 and 3.8 on Ease of Use, while those 60-69 and 70+ ranked it 3.0 and 2.7, respectively, potentially reflective of lower technical skills. Age did not impact Understandability. In the cancer genetics clinic, 86% of pts. completed the online survey, in ~ 1 week, compared to paper forms, which required reminders, and >4 weeks to obtain. Conclusions: In this pilot, InheRET accelerated appropriate referrals and efficient utilization of genetic counseling services; improvements to navigation are being implemented prior to dissemination.
