Evidence-based medicine resources available through the University of Otago Library, and those freely available, have been arranged here according to the 6S model proposed by Dicenso, Bayley and Haynes
See Dicenso, A., Bayley, L., & Haynes, R. B. (2009). Accessing pre-appraised evidence: fine-tuning the 5S model into a 6S model. [Editorial]. Evidence-based nursing, 12(4), 99-101. Follow this link to the article
This model proposes 6 layers of evidence sources. Using the upper level sources is more likely to give you a quicker result than the lower level sources.
1. Systems: decision support services that match information from individual patients with the best evidence from research that applies
2. Summaries: evidence-based textbooks, which integrate best available evidence from the lower layers
3. Synopses of syntheses: descriptions of systematic reviews, often found in e.g. evidence-based journal articles
4. Syntheses: systematic reviews provide a full range of evidence concerning management options for a given health problem.
5. Synopses of studies: evidence-based journal abstracts
6. Original Studies—most often examine only one aspect of management leaving decision makers to do their own critical appraisal of the evidence.
