The first step of the evidence-based practice process is to evaluate a nursing practice environment to identify a nursing problem in the clinical area. When a nursing problem is discovered, the nurse researcher develops a clinical guiding question to address that nursing practice problem.
For this assignment, you will create a clinical guiding question know as a PICOT question. The PICOT question must be relevant to a nursing practice problem. To support your PICOT question, identify six supporting peer-revised research articles, as indicated below. The PICOT question and six peer-reviewed research articles you choose will be utilized for subsequent assignments.
Use the “Literature Evaluation Table” to complete this assignment.
1. Select a nursing practice problem of interest to use as the focus of your research. Start with the patient population and identify a clinical problem or issue that arises from the patient population. In 200–250 words, provide a summary of the clinical issue.
2. Following the PICOT format, write a PICOT question in your selected nursing practice problem area of interest. The PICOT question should be applicable to your proposed capstone project (the project students must complete during their final course in the RN-BSN program of study).
3. The PICOT question will provide a framework for your capstone project.
4. Conduct a literature search to locate six research articles focused on your selected nursing practice problem of interest. This literature search should include three quantitative and three qualitative peer-reviewed research articles to support your nursing practice problem.
Note: To assist in your search, remove the words qualitative and quantitative and include words that narrow or broaden your main topic. For example: Search for diabetes and pediatric and dialysis. To determine what research design was used in the articles the search produced, review the abstract and the methods section of the article. The author will provide a description of data collection using qualitative or quantitative methods. Systematic Reviews, Literature Reviews, and Metanalysis articles are good resources and provide a strong level of evidence but are not considered primary research articles. Solid academic writing is expected, and documentation of sources should be presented using APA formatting guideline. See the attached sheets along with the above questions.

Clinical Issue Summary
Select a nursing practice problem of interest to use as the focus of your research. Start with the patient population and identify a clinical problem or issue that arises from the patient population. In 200–250 words, provide a summary of the clinical issue.
In mechanically ventilated patients in the ICU, does the utilization of a custom oral care protocol with chlorhexidine compared to a routine oral care protocol reduce the incidence of ventilator-associated pneumonia (VAP) during the length of stay in the ICU.
Cutler, L. R., & Sluman, P. (2014). Reducing ventilator associated pneumonia in adult patients through high standards of oral care: A historical control study. Intensive & Critical Care Nursing, 30(2), 61-68. http://dx.doi.org/10.1016/j.iccn.2013.08.005
Objectives: Implement and evaluate the impact of oral hygiene measures (teeth brushing, 1% oral chlorhexidine and oropharyngeal suction) on the incidence of ventilator-associated pneumonia (VAP) and the costs of prevention and treatment.
Design: A historical control study of all 1087 patients, mechanically ventilated for at least 48hours in a general adult critical care unit, between July 2009 and December 2011. The incidence of VAP in 528 patients before a practice change was compared with the incidence in 559 patients after a practice change. The clinical audit cycle was used to review compliance with existing standards and implement a regime of enhanced oral hygiene. The costs of changing the oral care regime and the treatment of VAP with antibiotics was calculated.
Setting: 22 bed combined intensive care and high dependency unit in England.
Main outcome measures: (1) Compliance with standards for oral care. (2) The incidence of VAP before and after the change.
Results: 91% (95% CI 90–93%) compliance with the standards for oral care was achieved throughout the 30 months of the study with very little difference before (90%, 95% CI 88–93%) and after (92%, 95% CI 90–95%) the changes in oral care standards were introduced. Of 528 patients mechanically ventilated for at least 48hours before the change, 47 developed VAP. The mean incidence of VAP was 0.09 (8.9%) (95% CI 0.07–0.12). The mean VAP per 1000 ventilator days was 13.6 (95% CI 13.1–14.0). After the change 24 of 559 patients developed VAP. The mean incidence of VAP after the change was 0.04 (4.1%) (95% CI 0.03–0.06). The mean VAP per 1000 ventilator days was 6.9 (95% CI 6.5–7.1). There was a £6319 ($10,112, €7518) cost saving on preventing and treating VAP following the practice change. A statistically significant difference (p<0.01) was seen between the incidence of VAP expected and that observed after the change in oral care. This represents a relative risk reduction of 0.53 (95% CI 0.25–0.71) and number needed to treat (NNT) of 21.
Conclusion: An enhanced oral care bundle, incorporating 1% Chlorhexidine Gluconate, was associated with a significant reduction in VAP and the costs of treating VAP. Limitations of the study relate to analysis of other variables, in particular severity of illness, between the two groups and the lack of agreement in the literature on VAP criteria, which limits generalisation of these findings.
