Emerg Med J July;19 4: Elements of a systematic review. Evidence based clinical practice.

The adequate well constructed research question allows for the correct definition of which information evidence is needed to solve the clinical research question 7,maximizes the recovery of evidence in the database, focuses on the research scope and avoids unnecessary searching.

Appl Nurs Res August;15 3: When analyzing the dressings available, they detected that modern dressings possess silver in their composition anti-microbial but are not estratwgia used.

World J Surg May;29 5: Selection of estrategis search terms: 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. Users should refer to the original published version of the material for the full abstract. The authors used PICO to describe all the components related to the identified problem and to structure the research question, which was: When a problem in health care is esttategia and a way to solve it is needed, a research question originates.


Part II—Searching evidence databases. Langenbecks Arch Surg October; 5: Data from the systematic review by Bergin and Wraight 16 are used estragegia exemplify the construction of the research question using the PICO strategy.


The PICO strategy helps in these definitions, because it orients the 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 esrtategia information available.

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. The authors of this systematic review demonstrated that the incidence of foot ulcers in diabetics is high and that this is a predictor of amputation in these patients.

The identification of the best evidence requires the construction of an appropriate research question and review of the literature.

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

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. This information will be important for the correct application of evidence-based medicine. It is this question which then dictates how research will be conducted, what study design is best suited to answer it and what results are expected. The PICO strategy for the research question construction and evidence search. The estratgeia known vocabularies of controlled descriptors are: Today, there are several clinical trials available in the databases.
