Undertaking and writing up a systematic review: a step by step guide

Abstract

Undertaking a systematic review is a challenging but ultimately rewarding exercise that helps to better inform medical practice through the synthesis of the best evidence in the literature for any given topic. One of the appeals of undertaking a systematic review is that there is not normally a requirement for ethical approval, funding or collecting new patient data. However, it must not be assumed that this means it will be an easy thing to do. A 12-step approach is proposed here, with a suggested template for manuscript writing. These can be used as a basic framework for the undertaking and writing of a systematic review. It is suggested that these be used in conjunction with expert advice and utilisation of other online and library services.
