Toward greater understanding of patient decision-making around genome sequencing.

In the era of next-generation sequencing, it is essential to collect and understand the patient outcomes that result from this new technology. One critical determinant of these is the process by which individuals first decide whether and how to pursue genome sequencing. In this perspective article, we examine the literature on adult patient decision-making in genome sequencing and identify current research gaps to address. Several studies have explored the motivations and concerns of patients undergoing sequencing; less attention has been paid to those who decline sequencing or to individuals from lower socioeconomic groups. Many factors that might play a role in the decision to pursue or decline sequencing, including trust, family dynamics and barriers to access, have yet to be explored fully. Future research that captures the experience of the wider population will produce a more generalizable understanding of the clinical, psychosocial, and economic outcomes of pursuing or declining sequencing.
