Operationalizing the Wilson-Jungner principles for the genomics era: Consensus recommendations from the International Consortium on Newborn Sequencing.
PURPOSE: For decades, the selection of disorders included in newborn screening (NBS) programs has been guided by principles published by Wilson and Jungner in 1968. As research explores the expansion of conditions included in NBS through genomic sequencing, there is a critical need for updated recommendations to address the opportunities and complexities of genomic data. METHODS: The International Consortium on Newborn Sequencing includes leaders from over 16 research projects investigating genomic NBS across the United Kingdom, Europe, United States, and Oceania. Consortium members were invited to participate in a modified Delphi study, aggregating opinion on the selection of conditions for genomic NBS through 3 rounds of online questionnaires, with feedback provided to participants between rounds. RESULTS: In round 1, 94 participants completed the questionnaire, and 10 of 43 statements reached consensus. In round 2, 81 participants completed the questionnaire, and 14 of 27 statements reached consensus. In round 3, 68 participants completed the questionnaire, and all 10 statements reached 72% or more consensus. CONCLUSION: The 10 consensus recommendations developed in this study can guide future research and public health programs performing genomic NBS. This process also identified key areas of participant discordance, highlighting important topics for future research.

Offering complex genomic screening in acute pediatric settings: Family decision-making and outcomes.
PURPOSE: Families of children in pediatric acute care who are offered ultrarapid genomic sequencing are making complex decisions during a high-stress period. To reduce complexity for families and clinicians, we offered genomic screening for the child and parents after the completion of diagnostic testing. We evaluated uptake, understanding, and service delivery preferences. METHODS: A cohort of 235 families who had completed ultrarapid diagnostic genomic sequencing at 17 Australian hospitals were offered up to 3 screens on their genomic data: pediatric-onset, adult-onset, and expanded couple carrier screening. We investigated decision making, understanding, and service delivery preferences using surveys at 3 time points (pre counseling, post counseling, and post result) and performed inductive content analysis of pretest genetic counseling transcripts. RESULTS: A total of 119 families (51%) attended genetic counseling with 115 (49%) accepting genomic screening. Survey respondents were more likely to find decisions about couple carrier screening easy (87%) compared with adult (68%; P = .002) or pediatric (71%; P = .01) screening decisions. All respondents with newly detected pathogenic variants accurately recalled this 1 month later. A delayed offer of screening was acceptable to most respondents (78%). CONCLUSION: Separating genomic screening from the stressful diagnostic period is supported by families who demonstrate good knowledge and recall. Our results suggest delaying genomic screening should be trialed more widely.
