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 authors used PICO to describe all the components related to the identified problem and to structure the research question, which was: Rev Latino-am Enfermagem maio-junho;13 3: The EBP previews methodologies and processes in order to identify evidence of whether a certain treatment or diagnosis is effective, strategies to evaluate the quality of studies and mechanisms to implement it estratdgia care.

Services on Demand Journal. Combination of components of the PICO strategy for the finalization of the search strategy: Emerg Med J July;19 4: Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use. Evidence based practice is the use of the best scientific evidence to support the clinical decision making.

PICO process

Selection of the search terms: The PICO strategy can be used to construct several kinds of research questions, originated from clinical practice, human and material resource management, the search of symptom assessment instruments, among others.

When a problem in health care is observed and a way to solve it is needed, a research question originates. This information will be important for the correct application of evidence-based medicine.

Evidence based clinical practice. 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 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 scientific information available.


Langenbecks Arch Surg October; 5: Wyatt J, Guly H. 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, 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.

World J Surg May;29 5: Identifying the research question and planning the project. Nowadays, there exists a large quantity of many times contradictory scientific information.

In addition, this paper provides a description of possible epidemiological designs that can be derived from this question, its advantages and disadvantages.

This abstract may be abridged. The PICO strategy for the research question construction and evidence search.

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. It is also very easy to access studies developed all over the world. The results obtained through such reviews are biased, do not exhaust all the literature available about the theme and are usually inconclusive.

This article describes the use of the PICO strategy for the construction of the research question and bibliographical search. This interface can be accessed on http: Number and size of randomized trials reported in general health care journals from to Part 1—well structured clinical questions. Semin Perinatol February; 21 1: 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.



Stages 1, 2, 3 and 4 represent the development of studies called systematic review, a fundamental research model inside EBP. No warranty is given about the accuracy of the copy. It is this question which then dictates how research will be conducted, what study design is best suited to answer it and what estratega are expected. Part II—Searching evidence databases. For this reason, it is essential that every researcher is familiarized with strategies to develop a research question, as each one of its components must be defined.

The most known vocabularies of controlled descriptors are: The search for evidence requires an adequate definition of the research question and the creation of a logical structure for the bibliographic pioct of evidence in literature, which facilitates and maximizes the research scope Traditional literature reviews nowadays called narrative reviews have been criticized for a long time because the bibliographic search and study selection method is not standardized and made explicit.
