Systems integrate information from the lower levels of the pyramid with individual patient records, producing a tailored recommendation for clinical decision-making. e.g. Computerized decision support systems (CDSSs)
Summaries look at all of the evidence from the lower levels of the pyramid, relying heavily on systematic reviews, where critical appraisal has already taken place. Recommendations for clinical practice are made based on the evidence, and each recommendation is graded according to the strength of the evidence.
Please note: practice guidelines are sometimes published in journals, therefore you can also search journal databases (e.g. CINAHL, Medline, PubMed) to find guidelines, limiting your publication type to Practice Guidelines. Another resource for finding practice guidelines is the TRIP meta-search tool found on the left-hand side of the guide - be sure to limit your results to Guidelines because TRIP contains resources from all levels of the pyramid.
A synopsis of synthesis provides a summary of an individual systematic review. It must be a high quality review to meet all of the criteria to be selected for summary.
Syntheses (Systematic Reviews) involve a systematic approach in which extensive and thorough searches of the literature are conducted to locate all research studies that would answer a particular question, and then rigorous selection criteria are applied to ensure inclusion of only the best studies that demonstrate sound methodology, validity, etc. Critical appraisal of the studies is conducted by two or more reviewers independently.
The systematic review summarizes and synthesizes the evidence found in the selected studies.
A synopsis of a single study provides a summary of an individual primary research study. The research study must be of high quality and meet the necessary criteria to be selected for summary.
Single studies refer to primary, original research studies conducted to answer specific clinical questions.
CINAHL, Medline & PubMed all feature a filter for Clinical Queries which will limit your search results to clinically relevant and scientifically sound studies of the following types: Therapy, Prognosis, Review, Qualitative, and Causation (Etiology).
