This document summarizes the work of Professor Alf Nicholson in developing a national model of care for children in Ireland from 1990-2014. Key aspects included reducing variation in care, developing algorithms to guide first responders, visiting all pediatric departments and specialties to develop models of care, creating a national charter for children, strengthening regional networks and outreach clinics, and developing a manpower plan for pediatrics. The overall goal was to avoid disadvantages based on location, improve interfaces between primary and secondary care, and establish a whole systems plan to guide child health in Ireland.
