Parental experiences of ultrarapid genomic testing for their critically unwell infants and children

Purpose To explore parental experiences of ultrarapid genomic testing for their critically unwell infants and children. Methods Parents of critically unwell children who participated in a national ultrarapid genomic diagnosis program were surveyed >12 weeks after genomic results return. Surveys consisted of custom questions and validated scales, including the Decision Regret Scale and Genomics Outcome Scale. Results With 96 survey invitations sent, the response rate was 57% ( n = 55). Most parents reported receiving enough information during pretest ( n = 50, 94%) and post-test ( n = 44, 83%) counseling. Perceptions varied regarding benefits of testing, however most parents reported no or mild decision regret ( n = 45, 82%). The majority of parents (31/52, 60%) were extremely concerned about the condition recurring in future children, regardless of actual or perceived recurrence risk. Parents whose child received a diagnostic result reported higher empowerment. Conclusion This study provides valuable insight into parental experiences of ultrarapid genomic testing in critically unwell children, including decision regret, empowerment, and post-test reproductive planning, to inform design and delivery of rapid diagnosis programs. The findings suggest considerations for pre- and post-test counseling that may influence parental experiences during the testing process and beyond, such as the importance of realistically conveying the likelihood for clinical and/or personal utility.
