- Assessing how much confidence to place in different types of research evidence is key to informing judgements regarding policy options to address health systems problems.
- Systematic and transparent approaches to such assessments are particularly important given the complexity of many health systems interventions.
- Useful tools are available to assess how much confidence to place in the different types of research evidence needed to support different steps in the policy-making process; those for assessing evidence of effectiveness are most developed.
- Tools need to be developed to assist judgements regarding evidence from systematic reviews on other key factors such as the acceptability of policy options to stakeholders, implementation feasibility, and equity.
- Research is also needed on ways to develop, structure, and present policy options within global health systems guidance.
- This is the third paper in a three-part series in PLoS Medicine on health systems guidance.
