Reviewing research evidence for nursing practice: systematic reviews highlights the key issues involved in conducting different types of systematic reviews - encompassing qualitative studies, quantitative studies and combining quantitative and qualitative studies. It enables nurses and researchers to understand the key principles involved in preparing systematic reviews and to critically appraise the reviews they read and evaluate their usefulness in developing their own practice. Each section starts with an overview of the methodology, followed by a selection of systematic reviews carried out in specialist areas of nursing practice. Part 1 explores systematic reviews and meta-analysis of quantitative research, part 2 explores meta-synthesis and meta-study of qualitative research and part 3 addresses integrative reviews that combine both qualitative and quantitative evidence. The final part explores the use of systematic reviews in service and practice development.
