- > In summary then, we can begin by outlining some pointers to when to do a systematic review: 1. When there is uncertainty, for example about the effectiveness of a policy or a service, and where there has been some previous research on the issue. 2. In the early stages of development of a policy, when evidence of the likely effects of an intervention is required. 3. When it is known that there is a wide range of research on a subject but where key questions remain unanswered – such as questions about treatment, prevention, diagnosis, or etiology, or questions about people’s experiences. 4. When a general overall picture of the evidence in a topic area is needed to direct future research efforts. 5. When an accurate picture of past research, and past methodological research is required to promote the development of new method- ologies.
