Abstract
Meta-analyses can provide clinicians with the evidence-based information necessary to effect change in patient care delivery. Meta-analysis, the application of statistical techniques to condense data from a group of individual studies, is the most sophisticated summary of research evidence. An example meta-analysis study of inadvertent surgical hypothermia is used in this article to describe how nurses can locate, evaluate, and apply synthesized research data for perianesthesia clinical practice. Without data to support decisions, nurses will increasingly be faced with decisions made by others based on cost-cutting measures alone. Although meta-analysis may resolve a controversy or solve a clinical problem, it will not provide simple statistical answers for complex problems or obviate the need for sound and compassionate clinical judgment. © 2001 by American Society of PeriAnesthesia Nurses.
