Resumen:

Systematic reviews and meta-analyses are proven tools for decisionmaking in health care, both for patients and for public policy. For example, nowadays they constitute a substantial part of evidence based clinical practice guidelines. However, the number of systematic reviews developed so far, and their use and application to improve the health of elderly has been somehow slow. This chapter describes in detail each of the steps necessary to conceptualize and conduct systematic reviews and meta-analysis. It begins with a description of the different uses these types of tools have today. Subsequently the differences they have with narrative reviews are given. With regard to the methodology to assemble them, it starts in the form of how the research question is formulated, which is the essence for the construction of each of systematic reviews. Then we continuewith the selection of studies, fi rst by searching in different electronic databases(e.g., Medline). Once studies are located, each of them should be reviewed thoroughly to determine if they comply strictly with the selection criteria. Finally,with the selected studies the next step is data extraction from each one, which eventually constitutes the results section of the systematic review. Noteworthy, in each of the steps we pointed out each of the aspects necessary to make the reviews with the highest quality. The last part of the chapter focuses on the different alternatives of meta-analyses and how they need to be carried out. © Springer International Publishing Switzerland 2015.
