To develop and evaluate a scalable national program to build confidence, competence and capability in the use of rapid genomic testing in the acute pediatric setting. We used theory-informed approaches to design a modular, adaptive program of blended learning aimed at diverse professional groups involved in acute pediatric care. The program comprised four online learning modules and an online workshop and was centered on case-based learning. We evaluated the program using the Kirkpatrick four-level model of training evaluation and report our findings using the RISE2 guidelines for genomics education and evaluation. Two hundred and two participants engaged with at least one component of the program. Participants self-reported increased confidence in using rGT, (p<0.001) and quiz responses objectively demonstrated increased competence (e.g., correct responses to a question on pre-test counseling increased from 30% to 64%; p<0.001). Additionally, their capability in applying genomic principles to simulated clinical cases increased (p<0.001), as did their desire to take on more responsibility for performing rGT. The clinical interpretation of more complex test results (such as negative results or variants of uncertain significance) appeared to be more challenging, indicating a need for targeted education in this area. The program format was effective in delivering multidisciplinary and wide-scale genomics education in the acute care context. The modular approach we have developed now lends itself to application in other medical specialties or areas of healthcare.
