It is also very easy to access studies developed all over the world. Having access to the knowledge produced about a certain subject is essential for the development of good research and adequate clinical action. In this review a description of the characteristics of a good research question and its construction by the strategy known as PICOT will be made. Evidence is what is clear, the confirmation of a truth that elicits no doubt.

Data from the systematic review by Bergin and Wraight 16 are used to exemplify the construction of the research question using the PICO strategy. When analyzing the dressings available, they detected that modern dressings possess silver in their composition anti-microbial but are not widely used.


Users should refer to the original published version of the material for the full abstract. Part II—Searching evidence databases. Bergin SM, Wraight P.

The PICO strategy helps in these definitions, because it orients estrategka construction of the research question and of the bibliographic search, and permits clinical and research professional, in case of doubt or questioning, to rapidly and accurately locate the best eztrategia information available. 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.

The PICO strategy can be used estrayegia construct several kinds of research questions, originated from clinical practice, human and material resource management, the search of symptom assessment instruments, among others. These terms allow for combinations of descriptors that will be used in the search, with AND for a restrictive combination, OR for an additive combination and NOT for an excluding combination.


It is this question which then dictates how research will be conducted, what study design is best suited to answer it and what results setrategia expected. The descriptors are classified as: Arch Dis Child August;90 8: Int J Nurs Pract December;7 6: Silver based wound dressings and topical agents for treating diabetic foot ulcers.

Combination of components of the PICO strategy for the finalization of the search strategy: EBP aims to improve estrategiia 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.

Nowadays, there exists a large quantity of many times contradictory scientific information. Table estrattegia presents the stages of EBP Elements of a systematic review.

Wyatt J, Guly H. Today, there are several clinical trials available in the databases. The internet and the portals of open-access journals allow for accessibility to knowledge, but this is not enough, because estraategia is necessary to know what to select from this immense source of information and how to do it.

The PICO strategy for the research question construction and evidence search

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 stagesAppl Nurs Res August;15 3: In the course of the twentieth century, health research techniques have been refined and clinical trials pickt improved.

This article focuses on the initial stage of EBP, the identification of evidence, which requires the adequate construction of the research question and bibliographic search. Use of Boolean operators: Such final strategy must be inserted in the search box existent in the databases, so that evidence is located by means of a bibliographic search.

Systematic review represents the use of a standardized method to synthesize data from multiple primary studies 8.
