Exploring individuals' experiences with self-reported unmet need for genetic testing.

Abstract

In practice, healthcare systems and insurers determine that there is "need" for genetic testing when there is potential for clinical utility. However, it is not currently known how the public understands the need for genetic testing and if this aligns with clinical utility. We recruited participants in Canada through a survey distributed through a market research company (Leger Opinion Panel). Participants who self-reported the need for genetic testing were then purposively sampled to complete a semi-structured virtual interview. We used an interpretive description approach and reflexive thematic analysis. We completed 19 interviews and found that participants' self-identified need for genetic testing was informed by their experiences with genetic information and the perceptions that genetic information is actionable (clinical utility) and has personal meaning (personal utility). Most participants would not be eligible for funded testing based on their personal and family history, however, they had unmet informational and psychological needs, indicating unmet need for genetic counseling. The public understanding of the need for genetic testing is complex and varied. Participants identified many benefits resulting from genetic testing which are not reflected in how need is operationalized in reimbursement decisions, however unmet expectations for testing contributed to medical distrust and dissatisfaction.
