Addressing conflicts of interest of ethical reviewers of health planning, management, policy and systems research proposals.

Steering health systems towards universal health coverage requires research on themes that are of particular interest to health planning, management, policy and systems researchers. Some issues, such as strikes regarded as illegal and health sector corruption, because of their social and political sensitivity have, for too long, remained outside adequate research inquiry. Their emergence in the research agenda raises some challenges for Human Research Ethics Committees, particularly related to their conflicts of interests as reviewers, that need clarification.
