Meta-analysis as a tool for evidence-based practice: an example using the Rice meta-analysis of smoking cessation interventions.
Enhanced quality of patient care and the prevention of errors are emphasized greatly in today's health care settings. Nurses are now held accountable for the care they provide and, as a result, nurses are responsible for incorporating solid scientific evidence into their practice. Published meta-analyses represent one source of such evidence. Meta-analyses offer statistical summarizations of all studies conducted about a particular phenomenon and more objective evaluation of the research often results. This article examines seven basic processes for evaluating meta-analyses and determining the value of their results for use in nursing practice.
