“I Didn't Have to Worry about It”: Patient and Family Experiences with Health System Involvement in Notifying Relatives of Genetic Test Results

Abstract

Introduction: In the USA, patients who undergo genetic testing for hereditary cancer risk are responsible for informing relatives about their genetic test results, but many relatives never find out they might be at risk. A health system-mediated relative notification program might help fill this gap, but questions remain about the acceptability of this approach. Methods: We analyzed qualitative data from a single-arm, nonrandomized, mixed-methods study to understand how patients and families experienced a new health system-mediated relative notification program. We invited all study participants to participate in semi-structured telephone interviews at 6–8 weeks after return of genetic test results. We used a template analysis approach to thematically analyze interview transcripts. Results: We interviewed 32 participants, including 17 probands and 15 relatives. Relatives reported positive experiences with the notification program, noting they felt in control of decisions and appreciated genetic counselor involvement in communicating the proband’s test results. Benefits of direct contact included reduced burden for probands, increased family discussions about health, and notification of relatives who otherwise would not have learned results. No participants reported adverse effects from the program. Conclusion: Overall, the relative notification program was acceptable to participants and supported probands in reaching at-risk relatives who otherwise might not have been notified. These findings could inform the implementation of future genetic risk family notification programs with the potential to improve uptake of cascade testing and advance cancer prevention and early detection efforts.
