Langenbecks Arch Surg October; 5: Nowadays, there exists a large quantity of many times contradictory scientific information. The authors used PICO to describe all the components related to the identified problem and to structure the research question, which was: Having access to the knowledge produced about a certain subject is essential for the development of good research and adequate clinical action.

Principles of evidence based medicine. These four components are the essential elements of the research question in EBP and of the construction of the question for the bibliographic search of evidence 7, Archie Cochrane United Kingdom exerted a profound influence on the assessment of medical interventions, establishing the importance of RCT in the evaluation of treatment effectiveness 5.
Once the research question is formulated, the following stage is the beginning of the bibliographic search for evidence, which allows for the recovery of evidence in the databases, and can be schematized in the following stagesWhen analyzing the dressings available, they detected that modern dressings possess silver in their composition anti-microbial but are not widely used. Today, there are several clinical trials available in the databases.

EBP aims to improve care through the identification and promotion of workable practices and, at the same time, through the elimination of inefficient and prejudicial ones 7minimizing the gap between the generation of evidence and its application in patient care.

Data from the systematic review by Bergin and Wraight 16 are used to exemplify the construction of the research question using the PICO strategy. Number and size of randomized trials reported in general health care journals from to RCT studies have showed conflicting results in situations with similar research objectives and objects and generate doubts regarding effectiveness, fundamentation, indications and results of several health practices.
