The Commission can strengthen its impact on children's health and healthcare services within current remits and resources by focusing on a number of key fields: planned and structured research, providing insight into optimal human resources and skills in child primary care, developing and using ethical means of listening to children's views, remedying the invisibility of children in data, measuring the quality of primary care from a child-centric perspective, understanding the economics of investing in children's health, developing e-health standards and evaluation, collaborative and harmonised use of downloaded research databases, understanding and respecting children's rights and equity, and appreciating and allowing for children's evolving autonomy as they grow up. An optimal model of primary care for children is proactive, inclusive, corporately linked, based on and providing
