Transforming Integrated Care Through Co-production: A Systematic Review Using Meta-ethnography.

Introduction: There is a requirement for health and care systems and services to work on an equitable basis with people who use and provide integrated care. In response, co-production has become essential in the design and transformation of services. Globally, an array of approaches have been implemented to achieve this. This unique review explores multi-context and multi-method examples of co-production in integrated care using an exceptional combination of methods. Aim: To review and synthesise evidence that examines how co-production with service users, unpaid carers and members of staff can affect the design and transformation of integrated care services. Methods: Systematic review using meta-ethnography with input from a patient and public involvement (PPI) co-production advisory group. Meta-ethnography can generate theories by interpreting patterns between studies set in different contexts. Nine academic and four grey literature databases were searched for publications between 2012-2022. Data were extracted, analysed, translated and interpreted using the seven phases of meta-ethnography and PPI. Findings: A total of 2,097 studies were identified. 10 met the inclusion criteria. Studies demonstrated a variety of integrated care provisions for diverse populations. Co-production was most successful through person-centred design, innovative planning, and collaboration. Key impacts on service transformation were structural changes, accessibility, and acceptability of service delivery. The methods applied organically drew out new interpretations, namely a novel cyclic framework for application within integrated care. Conclusion: Effective co-production requires a process with a well-defined focus. Implementing co-delivery, with peer support, facilitates service user involvement to be embedded at a higher level on the 'ladder of co-production'. An additional step on the ladder is proposed; a cyclic co-delivery framework. This innovative and operational development has potential to enable better-sustained person-centred integrated care services.
