Rise in “no indicated risk” primary caesareans in the United States, 1991-2001: cross sectional analysis

Abstract

Currently, clinicians can search systematic reviews within the Cochrane Library, where they can find the Cochrane Database of Systematic Reviews and DARE.If they cannot find a pertinent review, or their interest is other than prevention and treatment, or if they want to conduct a comprehensive search, they can use the strategies presented here to identify systematic reviews in Medline.Quick searches or searching for systematic reviews in topic areas where many are available may be optimal with a high precision strategy or with the strategy that balanced sensitivity and precision.On the other hand, guideline developers and researchers may want to use a highly sensitive strategy.For all, our strategies are most useful when they are preprogrammed into search interfaces, such as the Clinical Queries in PubMed, ready to be combined with topic specific terms.
