Establishing the Clinical Utility of First StepDx PLUS and NextStepDx PLUS Study

The study uses a randomized controlled study design of pediatric neurologists and developmental pediatricians and front-line (primary care) pediatricians to determine if use of FirstStepDx PLUS and Next StepDx PLUS are associated with higher clinical quality, less variability in clinical practice, and lower costs from decreased resource utilization. The Clinical Performance and Value Vignettes (CPV) used in this study simulate a clinical encounter for individuals with an atypical phenotype and clinical presentation indicative of a possible genetic disorder. We will measure the difference in combined diagnostic and treatment CPV® domain score post-intervention versus baseline comparing intervention and control groups
