Improved National Outcomes Achieved in a Cardiac Learning Health Collaborative Based on Early Performance Level

Objective Within the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC), a learning health network developed to improve outcomes for patients with hypoplastic left heart syndrome and variants, we assessed which centers contributed to reductions in mortality and growth failure. Study design Centers within the NPC-QIC were divided into tertiles based on early performance for mortality and separately for growth failure. These...
