A high-quality systematic review is described as the most reliable source of evidence to guide clinical practice. The purpose of a systematic review is to deliver a meticulous summary of all the available primary research in response to a research question. A systematic review uses all the existing research and is sometime called ‘secondary research’ (research on research). They are often required by research funders to establish the state of existing knowledge and are frequently used in guideline development.

A systematic review uses all the existing research and is sometime called ‘secondary research’ (research on research). They are often required by research funders to establish the state of existing knowledge and are frequently used in guideline development. Systematic review fi ndings are often used within the healthcare setting but may be applied elsewhere. For example, the Campbell Collaboration advocates the application of systematic reviews for policy-making in education, justice and social work.

the evidence is synthesised. This process may or may not include a meta-analysis. A meta-analysis is a statistical summary of the fi ndings of independent studies.4 Meta-analyses can potentially present more precise estimates of the effects of interventions than those derived from the individual studies alone. These strategies are used to limit bias and random error which may arise during this process. Without these safeguards, then, reviews can mislead, such that we gain an unreliable summary of the available knowledge.
