South Western Sydney (SWS) is one of the fastest growing regions in the state of New South Wales (Australia). Much of the population live in local government areas (LGAs) with levels of disadvantage higher than the state average, with a predominance of non-communicable and chronic diseases that are typically associated with age-related and behavioural factors. This necessitates the management of social determinants of health through the integrated provision of primary and social care. The SWS Local Health District and Primary Health Network is exploring the potential of community health alliances (CHAs) as an innovative approach to support the provision of integrated health services. CHAs are a population health approach for addressing health challenges faced by people who share a common area of residence, sociocultural characteristic or health need, and are characterised by a shared mission, shared resource needs and acquiring/developing necessary organisational knowledge and skills. We explore how CHAs operate as social enterprises that utilise digital health and citizen engagement to deliver integrated people-centred health services (IPCHS) by conducting two case studies of CHAs operating in SWS: in Wollondilly and Fairfield LGAs. Using this approach, we aim to unpack the conceptual convergence that enables social enterprises to utilise digital health interventions and citizen engagement strategies to co-produce IPCHS with a view to developing theory and a framework for engaging digital citizens in integrated primary health care via social enterprise.
