The informed consent process in health research with under-served populations: a realist review protocol.

Findings of this realist review will highlight how the informed consent process in health research affects the experience and decision-making process of potential participants from under-served populations. They will be written up in accordance with RAMESES guidelines and disseminated to patients and the public, health researchers, health professionals and policymakers through peer-reviewed publication, presentations and discussions. The review will contribute to our understanding of the mechanisms that cause both positive and negative outcomes in the informed consent process for those whom are often under-represented in health research to inform policy, study design and delivery.
