Welcome to Guidelines International Network

The Guidelines International Network, or GIN, is the connector in the guideline world. Established in 2002, we have 119 organisational members and 139 individual members from 56 countries, as of 1st April 2025, – all with a common goal of improving healthcare, through using evidence and implementing evidence-based guidelines.

GIN’s aims are simple – to enable and facilitate networking and collaboration, whether national or international, bring the best minds together and support continuous learning and improvement and at the same time, reduce duplication of effort across the guideline world.

You can view our five year strategy here.

The organisation is led by an elected, international Board of Trustees.
