Norman Saunders was a respected academic community paediatrician who was passionate about the care of children with medical complexity. Following his untimely death at age 60, patients, friends, and colleagues raised funds to create the Norman Saunders Complex Care Initiative (NSCCI). Dr. Saunders’s vision was a comprehensive, coordinated, and integrated clinical program for children with medical complexity that was informed by research evidence. The objective of this review was to evaluate the impact of targeted philanthropic funding on research, clinical care, and policy. Since 2006, NSCCI funds have been used to support interdisciplinary and innovative research. Funded projects have reflected a breadth of research questions (clinical care, training, health system delivery, social determinants), disciplines, and methods, and the research results have informed and helped build an internationally renowned clinical program in complex care. Philanthropic funding was the foundation for the NSCCI, which over the last 15 years has built research and clinical capacity, catalysed clinical and research networks, helped train paediatric residents, influenced policy, and improved the health and well-being of children with medical complexity and their families across Canada, and beyond.
