versus silicone Foley catheters in reducing catheter associated urinary
tract infections in hospitalized patients
Introduction
This research explores the effectiveness of silver alloy coated urinary catheters versus silicone Foley catheters in reducing catheter associated urinary tract infections in hospitalized patients. Therefore, in constructing the PICO question the obvious inquisition pertains to whether silvery coasted urinary cathers have a better patient outcome than silicone Foleys cathers.
Construction of PICO question
Consequently, the distinct PICO question reads, can urinary tract infection rates be reduced among hospitalized patients when silver alloy coated catheters are used versus silicone Foleys ?
Identification of key terms
Key terms are hospitalized pateints; urinary tract infection; silver coated catheters; silicone Foleys cathers and catherization
Description of the population, intervention, comparison, and outcome of the question.
P- population/patients is defined in the research proposal as hospitalized patients; I- intervention relates to catherization; C – comparison defines the use of silver alloy catheters versus silicone Foleys and is reduction of urinary tract infection and O – outcome reduction in hospital related urinary tract infections
Description of at least 2 EBP model(s) appropriate for focus area
critique similarities and differences of models.
Two evidenced based models have been selected form review in this proposal. They are the Stevens five star model and the EBM traid.
Stevens Evidence based model
This model is depicted as a five star diagram beginning with knowledge discovery clockwise moving into evidence summary; translation into practice recommendations; integration into practice and evaluation. It is a simple clear method of declaring evidence according to scientific discovery. Importantly, the model is applicable to this research in providing evidence pertaining to the potential reduction of urinary tract infections in hospitalized pateints when silver alloy catheters are used versus silicone Foleys. The stages mentioned above will be applied when identifying evidence information derived from this study (Stevens, 2004).
Evidence based medicine traid
The evidence based medicine traid is a model applied to evaluating evidence contained in research studies. As in the Stevens evidence based model there are five significant areas of evaluation. They are converting information needs into answerable questions; tracking with maximum efficiency the best evidence necessary to answer them; critically appraising that evidence for its validity and usefulness; applying results of this appraisal to practice and evaluating performance after application (Sackett, Strauss & Richardson, 2000).
Critique similarities and differences of models.
Obvious similarities pertain to five specific categories highlighted in the models. The first stages are similar because it requires that the analyst deducts knowledge aligning them with what is needed for evidence application. Stevens (2004) describes this as knowledge discovery. The important differences lies in EBM asking questions. Stevens (20004) did not say how knowledge would be discovered. However, it is clarified in the evidence based medicine model to specify that this begins by asking questions.
Steven’s (2004) evidence summary could be linked to EBM’s tracking for the best evidence. Likewise translation and integration of evidence base practice are embodied in EMB’s critical appraisal phases where evidence is validated according to certain criteria. The last phases/stages in both models are the same; evaluation, specifically assessing how translation of evidence is performed.

Conclusion
Selection of an evidence grading system such as the one cited in the
directions above and rate at least four studies, using the EB Review Matrix to record your assessments.
Description of the relationship between levels of evidence
and grades of recommendations.
Levels of evidence pertain to the type of studies/material from which evidence was obtained and how was it retrieved. Precisely, how valid were the studies producing this degree of evidence and the depth of it. Grades are directly related to the evidence reinforcing the extent of research conducted to obtain the evidence. For example, randomized control trials are considered level 1 evidence with a grade A because the data retrieved is from primary sources.
