Incidental Genomics

Sponsor: Unity Health Toronto

Summary

Health care providers (HCP) are increasingly using genomic sequencing (GS) to diagnose diseases and target treatment for patients. However, GS may incidentally reveal inherited risks for thousands of current and future diseases. Guidelines recommend HCP inform patients of incidental GS results. GS is a relatively new technology, raising many questions about its adoption in clinical care, including: What are the psychological harms, health outcomes, clinical utility and economic costs of receiving primary and incidental GS results? We will use a randomized controlled trial (RCT) to evaluate whether patients receiving incidental GS results will report higher levels of distress and more risk reducing behaviors compared to patients receiving GS for their primary indication alone. We will explore the personal utility of GS via in-depth interviews with a subset of patients. Clinical utility for cancer and incidental results will be evaluated through diagnostic yield, clinical actions triggered by GS results and in-depth interviews with a subset of patients and providers. The economic impact will be evaluated in two ways: (a) health service use will be assessed retrospectively using billing records from the Institute of Clinical Evaluative Sciences (ICES); and, (b) participants' personal costs incurred as a result of GS will be assessed via surveys. Participants will be adult cancer patients who have received negative single gene or panel test results and who have been determined by their health care provider to be a candidate for GS.
