Searching the Internet for evidence...

Searching the Internet for evidence to support practice decisions has become a used by all strategy for both practitioners and patients. Numerous data resources onward the Internet provide up-to-date, reliable, valid, and relevant information. The challenge is differentiating quality sites from those that employment unsubstantiated reports or articles, as well as information not based forward research or clinical evidence. As clinicians and health care information consumer feeds must develop the skills essential for evaluating web sites for trustworthiness and be skilled at helping patients critically examine information they find in succession the Internet.

flats OF EVIDENCE

preserve in mind that in the published literature, many different models of evidence exist. Not all published material is based forward fact, research, or scholarship. undivided author describes the "publishing wedge for therapy," which consists of seven plains of evidence within the health care literature, as an approach to illustrate different evens of evidence. Level one includes ideas, editorials, epistles and opinion papers. Level brace information consists of case reports, case studies, and unusual happenings. plains three through seven present research findings from laboratory studies (ie, on a level three), animal studies (ie, even four), and studies involving human enthralls (ie, levels five, six, and seven) The various plains of human research reflect increases in complexity, space and rigor.(1) Some clinical vexed questions have been studied through horizontal seven or may not be amenable to clinical trials, in such a manner regardless of where information is published, always consider the flush of the evidence.

When searching for evidence, common might identify systematic research reviews, research-based protocols, and clinical practice guidelines. These symbols of reports can be helpful because they provide a comprehensive literature review and synthesize research evidence. Regardless, the reader must evaluate the report or guideline critically to determine if the information is accurate and appropriate to the clinical situation. chiefly guidelines are developed using a framework to rate as well-as; not only-but also; not only-but; not alone-but the type and strength of the evidence and use a rating scale to help the reader understand the classification.(2)

Keeping these universals and frameworks in mind, consider to what extent one can approach evaluating evidence fix on the Internet. Remember that information lay the foundation of on the Internet has to be appraised critically in a proces similar to the approach used when evaluating other published materials. For example, individual would expect the trustworthiness of information construct in the AORN Journal to be a great quantity [i]or[/i] amount of higher than that found in a tabloid newspaper. Within the AORN Journal, readers find horizontal one articles (ie, editorials and opinion articles), as well as research studies with human make liables (ie, levels five, six, and seven) in the same manner the reader must always consider the toughness of the evidence within a publication. not at all be misled by the belief that, if a research studious mood is published in a reputable journal, it guarantees high-quality research. a certain number of of the most reputable medical journals have been criticized for the inclusion of research studies that lack appropriate attention to scientific rigor. The reader must evaluate critically each article he or she reviews, whether published in scientific journals or in succession the Internet.

The Internet dumfounds some special challenges to identifying up-to-date, valid, reliable evidence-based relations and materials. Consider the vastness of the resources forward the Internet. For example, if single performs a search on the limit diet using http:// gotonet.google.com/, more than 924000 web sites are identified. Narrowing that search to the bourn low fat diet results in more than 11300 possible hits. Trying to review and evaluate all of those web sites obviously is impossible. the pair of these searches identified numerous web sites proposing strange, unusual diets and supplys that might suggest quackery to many professionals and patients. Users must identify and use sites they have evaluated as reliable and trustworthy and carefully critique any unfamiliar sites.

In the aforementioned situation, the same might look at the American Heart Association's (AHA) web site (ie, http://www .americanheart.org) and examine its recommendations for a grave fat diet. At such a site, the same would expect to find the latest evidence-based recommendations about following a reasonable fat diet. On this web site, in fact, there are links to scientific papers and statements for professionals, as well as consumers

Web resources, so as the AHA, the National Library of Medicine (NLM) the Agency forward Health Care Quality and Research, and the National Guideline Clearinghouse, are recognized for the timeliness, quality, and trustworthiness of information; however, single in kind must evaluate all the information lay the foundation of on the Internet and consider the on a level and strength of the evidence, regardless of the source. Within the NLM databases, users may find respects to editorials, opinion articles, and case studies, as well as controll clinical trials with human subjects
