Primary Care Provider Perspectives on Expanded Genomic Screening in Children

Objective(s): Expanding pediatric genomic screening beyond current newborn screening presents both opportunities and challenges to primary care providers. We are developing a novel paradigm called Age-Based Genomic Screening (ABGS), which will incorporate targeted genomic sequencing for select, highly actionable genetic conditions into routine care at relevant time-points throughout childhood. We surveyed pediatric primary care providers in North Carolina to identify potential ABGS implementation determinants and strategies to address them. Study design : We disseminated an electronic survey to family medicine and pediatric primary care clinicians. Survey items were modeled on constructs previously identified as important to genomic medicine and assessed perceived utility, benefits, barriers, and facilitators of implementing targeted genomic screening in pediatric primary care. Data were analyzed using descriptive statistics and content analysis, as appropriate. Results : A total of 93 individuals completed the survey. Over 85% of respondents agreed that genomic screening was important and impactful in their patient care but about 30% lacked confidence in their ability to implement it in their practice. The most cited benefits of the ABGS program were related to readiness for implementation and the evidence, strength, and quality of the intervention. The most concerning barriers included cost for patients and available resources, with 87% and 75% of respondents having extreme or moderate concern for these barriers, respectively. Conclusion(s) : Our findings have implications both for the design of the ABGS pilot program and directions for future research in genomic implementation. In particular, the blueprint for the pilot program must include specific plans for ensuring primary care providers have the time and resources available for shared decision making with their patients about engaging in genomic screening.
