Co-designing policy with Aboriginal and Torres Strait Islander peoples: a protocol.

Objectives and importance of study: In the public service context, co-design is novel and ever-expanding. Co-design brings together decision-makers and people impacted by a problem to unpack the problem and design solutions together. Government agencies are increasingly adopting co-design to understand and meet the unique needs of priority populations. While the literature illustrates a progressive uptake of co-design in service delivery, there is little evidence of co-design in policy development. We propose a qualitative study protocol to explore and synthesise the evidence (literary, experiential and theoretical) of co-design in public policy. This can inform a framework to guide policymakers who co-design health policy with Aboriginal and Torres Strait Islander people. Methods: The study design is informed by a critical qualitative approach that comprises five successive stages. The study commences with the set-up of a co-design brains trust (CBT), comprising people with lived experience of being Aboriginal and Torres Strait Islander who have either co-designed with public agencies and/or have health policymaking expertise (stage 1) The brains trust will play a key role in guiding the protocol's methodology, data collection, reporting and co-designing a 'Version 1' framework to guide policymakers in co-designing health policy with Aboriginal and Torres Strait Islander people (the framework). Two realist evaluations will explore co-design in health policy settings to understand how co-design works for whom, under what circumstances, and how (stages 2 and 3) The findings of the realist evaluations will guide the CBT in developing the framework (stage 4). A process evaluation of the CBT setup and framework development will assess the degree to which the CBT achieved its intended objectives (stage 5). Conclusion: The proposed study will produce much-needed evidence to guide policymakers to share decision-making power and privilege the voices of Aboriginal and Torres Strait Islander people when co-designing health policy. Learnings from this translational research will be shared via the CBT, academic papers, conference presentations and policy briefings.
