Decision-making, attitudes, and understanding among patients and relatives invited to undergo genome sequencing in the 100,000 Genomes Project: A multisite survey study
24th January 2022
Abstract
Purpose: The purpose of this study was to assess decisions, attitudes, and understanding of participants (patients, parents, relatives) having genome sequencing for rare disease diagnosis.
Methods: This study involved a cross-sectional observational survey with participants in the 100,000 Genomes Project.
Results: Survey response rate was 51% (504/978). Most participants self-reported that they had decided to undergo genome sequencing (94%) and that this was an informed decision (84%) with low decisional conflict (95%). Most self-reported that they had chosen to receive additional findings (88%) and that this was an informed decision (89%) with low decisional conflict (95%). Participants were motivated more by the desire to help others via research than by the belief it would help them obtain a diagnosis (Z = 14.23, P = 5.75 × 10-46), although both motivations were high. Concerns were relatively few but, where expressed, were more about the potential psychological impact of results than data sharing/access (Z = 9.61, P = 7.65 × 10-22). Concerns were higher among male, Asian or Asian British, and more religious participants. General and context-specific understanding of genome sequencing were both moderately high (means 5.2/9.0 and 22.5/28.0, respectively).
Conclusion: These findings are useful to inform consent guidelines and clinical implementation of genome sequencing.
