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.
Once your protocol for your systematic review has been completed, it is necessary to register it. Registering a systematic review enhances the transparency of the review, reduces publication bias and reduces the risk of duplicate reviews.
You can also register your protocol with the following organizations
STARLITE refers to the standards for reporting literature searches (Sampling strategy, Type of study, Approaches, Range of years, Limits, Inclusion and exclusions, Terms used, Electronic sources)

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.
