This milestone-driven Funding Opportunity Announcement (FOA) invites applications for single-site clinical trials that: (1) address barriers that impede population-level implementation of case finding and cascade screening (i.e., blood relatives of FH index cases are systematically contacted based on
their risk according to the pattern of inheritance); (2) explore implementation science methodologies to assess the uptake, cost-effectiveness, feasibility, and scalability of family-based cascade screening programs for familial hypercholesterolemia (FH); (3) develop or improve machine learning algorithms and data mining techniques to find high-risk individuals using electronic health records (EHRs); and (4) optimize treatment strategies and health outcomes.
