Experiencing acute genomic care: perspectives from parents in the neonatal and paediatric intensive care units towards rapid genomic sequencing.

Rapid genomic sequencing (rGS) is increasingly used in neonatal and paediatric intensive care units (ICUs) to inform diagnosis and guide management of critically ill infants and children. Although rGS has a high diagnostic yield and potential to influence treatment and care planning decisions, little is known about how families experience rGS in the ICU and the emotional and contextual factors influencing their testing-related decisions. We conducted semi-structured interviews with twenty-three parents of infants who consented to rGS in an ICU at two tertiary hospitals in Toronto, Ontario, Canada; all interviews took place in close proximity to the decision to pursue rGS. Parents' experiences with rGS and the related genetics consultation demonstrated a complex interplay of emotional, pragmatic, relational, and temporal 'sense-making' to grasp what was happening. Overall, parents felt overwhelmed in the ICU. Some de-prioritized genetic testing compared to other aspects of care while others reflected negatively or ambivalently on rGS or felt that it was implicitly expected that they pursue it. We conclude that an rGS approach tailored to the ICU setting is needed. Consideration should be given to distributing complex decisions (such as those relating to primary vs. secondary findings) across multiple briefer visits, and alleviating decisional burden by reframing rGS as one of the many shared decisions made with families in this setting.
