1: Introduction

This open access textbook aims to help you to write simple narrative reviews, which are commonly used in the health sciences to synthesise research evidence to guide practice and policy. The book is an introduction to how to critically evaluate research, how to compare different aspects of research studies, and how to synthesise and interpret research evidence. In its broad focus, this book reflects the ways reviews are used across a range of health practices, particularly in non-clinical areas.

The book is not a definitive text that covers all steps to conduct a thorough narrative review. Rather, the intention is to address a gap we have observed where students are often asked to undertake synthesis of health evidence based on assumptions about their skills and knowledge. In our undergraduate teaching, we have found that by addressing these gaps through worked examples and activities, we help students to build their understanding of the complex issues involved. You may find that specific conventions exist in different discipline areas – for example, in particular clinical areas. This book provides general guidance on common tasks; you will need to look elsewhere for information about such specific needs.

The book starts by introducing different types of reviews and then describes the steps required to undertake a review, with particular focus on detailing methods and considering review findings or results. A variety of tools, examples and links to other resources are provided to give a practical guide to writing clearly about health research.

To get the most out of this textbook, use the links  provided in the different sections. These will take you to published examples, and this should help with your understanding. There are also pop-up links to remind you of key terms, and some practice examples to help you get started.
