Evidence-based nursing Web sites: finding the best resources.

Evidence-based nursing is becoming an increasingly widespread phenomenon in the nursing profession. As the evidence-based nursing movement grows, the Internet/World Wide Web has become a vital information link for keeping pace with current science and medical advancements. This article describes Internet resources currently available to support evidence-based nursing practice, presents practical search methods for locating these resources, and suggests criteria for evaluating the "evidence" available on the Internet. Results of an Internet search for Web sites that met the proposed criteria for support of an evidence-based nursing practice located only three sites. The sites are described and evaluated for their usefulness. The authors demonstrate that although many Internet resources are available to nurses, few sites provide information or evidence supported by valid research.
