Since implementation of GHT differed across the five Primary Care Networks (PCNs) in which it has been implemented, a case study approach was undertaken to explore how diverse contextual factors enabled or challenged the growth of place-based approaches to health and wellbeing. The aims of the study were:

1. To describe delivery and reach of GHT in each of the five East Surrey PCNs
2. To identify the ‘active ingredients’ needed for successful development and implementation of GHT
3. To identify the impact on citizens who participate in a GHT initiative
4. Develop a framework for implementing GHT in PCNs, detailing how collaborations can successfully cultivate local conditions for health and wellbeing
5. Pilot the framework in one PCN to gather early learnings

In order to achieve these aims, the study undertook a mixed methods case study design underpinned by two implementation frameworks which informed the design of data collection, as shown below.
