Determining the Credibility of Evidence and Resources

If you do not have an issue of interest from your personal nursing practice, then review the optional Case Studies presented in the resources and select one of those as the basis for your assessment.

Instructions

For this assessment, select an issue of interest an apply the PICO(T) process to define the question and research it.

Your initial goal is to define the population, intervention, comparison, and outcome. In some cases, a time frame is relevant and you should include that as well, when writing a question you can research related to your issue of interest. After you define your question, research it, and organize your initial findings, select the two sources of evidence that seem the most relevant to your question and analyze them in more depth. Specifically, interpret each source’s specific findings and best practices related to your issues, as well explain how the evidence would help you plan and make decisions related to your question.

If you need some structure to organize your initial thoughts and research, the PICOT Question and Research Template document (accessible from the “Create PICO(T) Questions” page in the Capella library’s Evidence Based Practice guide) might be helpful.

In your submission, make sure you address the following grading criteria:

Define a practice issue to be explored via a PICO(T) approach.
Identify sources of evidence that could be potentially effective in answering a PICO(T) question.
Explain the findings from articles or other sources of evidence.
Explain the relevance of the findings from chosen sources of evidence to making decision related to a PICO(T) question.
Communicate using writing that is clear, logical, and professional with correct grammar and spelling using the current APA style.
Example Assessment: You may use the following to give you an idea of what a Proficient or higher rating on the scoring guide would look like:

Your assessment should meet the following requirements:

Length of submission: Create a 3–5-page submission focused on defining a research question and interpreting evidence relevant to answering it.
Number of references: Cite a minimum of four sources of scholarly or professional evidence that support your findings and considerations. Resources should be no more than 5 years old.
APA formatting: Format references and citations according to the current APA style.

reating a question using the PICOT elements will provide a framework for the research you need to conduct an evidence-based study or to make an evidence-based decision.

PICOT Elements:
(P) – Population, Patients or Problem: The sample of subjects used in a study, or the problem being addressed.

(I) – Intervention: The treatment that will be provided to subjects enrolled in your study.

(C) – Comparison or Control: Identifies an alternative intervention or treatment to compare. Many study designs refer to this as the control group. If an existing treatment is considered the ‘gold standard’, then it should be the comparison group. A control group is not required for every type of study.

(O) – Outcome: The clinical outcome that measures the effectiveness of the intervention.

(T) – Time: Duration of the data collection. Some versions don’t include this element, and time may not be specified in cases where the question is focused on prediction or diagnoses.

PICOT Question Formats:
Intervention: In (P), how does (I) compared to (C) affect (O) within _ (T)?

Prognosis/Prediction: In (P), how does (I) compared to (C) influence/predict (O) over _ (T)?

Diagnosis or Diagnostic test: In (P) are/is (I) compared to (C) more accurate in diagnosing (O)?

Etiology: Are (P), who have (I) compared to those without (C) at risk for/of (O) over (T)?

Meaning: How do_______ (P) with (I) perceive (O) during _ (T)?

Example PICOT Questions:
In acute care hospitals (P), how does having a rapid response team (I) compared with not having a response team (C) affect the number of cardiac arrests (O) during a three-month period (T)?
In women with gestational diabetes (P), how does a monitored diet and exercise program over the course of pregnancy (I &T), compared to the use of metformin only (C) reduce the incidence of high birth weight babies(O)?
In patients admitted for acute myocardial infarction (P), how well does the hospital’s new data model created from EMR data (I) compared to current practices (C) predict readmission rates (O) within 30 days after initial discharge (T)?
