Main Article Content
Keywords
PubMed, MeSH, Clinical research
Abstract
In the process of solving doubts generated in the process of medical care, the amount of articles appearing during the search is so vast, that a strategy must be considered to refine it. The present article describes the process for searching and selecting information that may help us answering to our patients’ needs. Judgment of the quality and relevance of the response will depend on each reader. The search has to be done in peer-reviewed sites, and for that reason, we recommend PubMed and to start the search after breaking down the PICO acronym, where P = patients, I = intervention, C = comparator and O = outcome. The PICO acronym shares components with the classical research architecture model described by doctor Alvan R. Feinstein. A good search must be involved with the answer to our question in the first 20 articles; otherwise, the search will have to be more specific by using filters.
