In evidence-based medicine, clinical decision-making is based on the integration of individual expertise, the best available evidence from systematic research and the needs and values of the patient. A systematic review includes a comprehensive search for primary studies on a particular clinical question, the critical evaluation of these studies and a synthesis of results according to a pre-determined methodology which may include meta-analyses of data. PubMed Health have produced a useful introduction, What is a Systematic Review?
The Campbell Collaboration prepares, maintains and disseminates systematic reviews in education, crime and justice, and social welfare. This includes a library of systematic reviews and review templates.
These templates will enable you to record your literature searches by indicating your search strategy, keywords, filters, limits and results.
Rapid reviews are similar to systematic reviews in their attempt at answering a clinical question to inform decision-making. However, the rapid review has a much shorter time frame, fewer databases are searched and there is often limited or no hand searching or grey literature searching done. This would increase the risk of bias.
