Navigating direct-to-consumer genetic testing: experiences, decisions and perspectives of Dutch users.

Insights into the perspectives, decision-making and experiences of non-US consumers regarding health-related direct-to-consumer genetic testing (DTC-GT) are currently lacking. These insights are essential to allow the implementation of consumer-tailored approaches that facilitate responsible use of DTC-GT. To fill this knowledge gap, the present study employed interviews to examine the consumer journeys of twenty Dutch health-related DTC-GT consumers. Overall, participants appeared quite satisfied with their DTC-GT consumer journeys. Participants' initial contacts with DTC-GT, as well as their pre-test information acquisition, occurred via a diversity of sources. Participants' pre-test expectations revealed considerable presumed clinical utility of DTC-GT. Feeling unheard within the regular healthcare system supported multiple participants' decisions to undergo health-related DTC-GT. Participants mentioned a modifying effect of price on their decision-making, and several participants stated not having considered potential negative consequences of DTC-GT prior to DTC-GT usage. Several potentially adverse consequences of undergoing DTC-GT were identified that could affect individual consumers, the regular healthcare system, and society as a whole. Three considerations to potentially stimulate responsible use of DTC-GT aligning with participants' needs and preferences were derived, namely improving pre-test information provision, implementing adequate post-test support systems for consumers, and development, implementation and enforcement of cross-border regulation and legislation. Based on these findings, we advocate for stakeholder discussions to further explore the feasibility and desirability of translating these considerations into deliverables. Ultimately, these deliverables could aid in empowering (potential) consumers for responsible use of health-related DTC-GT.
