Purpose:

This Assignment is helpful in developing the groundwork for understanding and integrating evidence-based practice in healthcare throughout the rest of the course. In this Assignment you will have the chance to see how the research you look for can be applied in the work you do in your practice.

Overview:

You will select a topic relevant to your practice area, post the topic to Discussion Board 2 for feedback, research the topic, and write a scholarly paper.

From the chapter readings and discussion, formulate a 3–5 page scholarly paper in APA format, providing an overview of the terms and function of EPB. An introduction, discussion and conclusion is expected in the overview on this topic

Directions:

  1. Formulate the question.
  2. Using the Cochrane database, research the question using the PICOT model and key words.
  3. Post your topic and a short summary of results for feedback from your instructor and peers by Day 5.
  4. Write a 3–5 page paper, reviewing evidence-based practice, as it relates to your practice question and integrate feedback from the instructor and/or peers.
  5. Include a minimum of three evidence-based references.

Assignment Requirements:

Before finalizing your work, you should:

  • be sure to read the Assignment description carefully (as displayed above);
  • consult the Grading Rubric (under the Course Resources) to make sure you have included everything necessary; and
  • utilize spelling and grammar check to minimize errors.

How

Concepts of evidence based practice
Rapid Critical Appraisal to Evaluate Evidence

Rapid critical appraisal is the opportunity to review evidence in a timely fashion. The ability to look at evidence and review it in a timely fashion will help your practice. You will learn how to look at the evidence that is
returned from your database search, and identify what level of evidence is available from your search. For example, being able to identify that a randomized control trial is a reliable source of evidence, rather than an
expert’s opinion.

Five Components of a PICOT

Recognizing the five components of PICOT questioning is the most pivotal aspect of evidence-based practice. Through PICOT, you can determine the patient population that you are working with, the intervention that you
propose (based on the research), a comparison intervention and then review the outcome and the time it takes to reach the outcome. For example, determining how long it takes for the evidence-based intervention to
improve the quality of life of a patient with terminal cancer.

P = patient, population, or problem

I = intervention, risk factor, assessment tool, or prognostic factor under scrutiny

C = comparison (alternative to intervention; at times this element may be absent)

O = outcome

T = time (Is there a certain period of time that must transpire for the intervention to produce an outcome? At times this element may also be absent.

How to Identify the Corresponding Research Design for the Foreground Question

As you develop a PICOT format, you decide what research design you will use that best meets the needs of your clinical question. For example, if the intervention is a medication, then a case control study would be ideal to
determine if the medication is effective compared to patients that do not receive the medication.

How to Identify the Corresponding Research Design for the Foreground Question

You will be able to identify the importance of evidence, recognizing that expert opinion and clinician opinion are the lowest level of evidence, with meta-analysis and randomized control trials at the top of the hierarchy.

Difference Between Foreground and Background

Foreground and background information must be distinguished for effective evidence-based PICOT development.

Foreground information can be answered based on scientific evidence about diagnosing, treating, or even assisting patients. This would be the actual clinical question being researched. So, for example, the question
of which analgesic works best to reduce a fever in a child would be foreground information
Background information is broader in scope as it helps develop the foreground question. For this example on analgesic questioning, the background information would be “how do analgesics work in children?”

Cranberries for Preventing Urinary Tract Infections

The purpose of evidence-based practice is to provide the most effective, up-to-date patient care, resulting in the best patient outcomes. Nursing research involves the development of new knowledge, on a particular topic, which may then be translated into evidence-based practice. The purpose of this paper is to assess the effectiveness of cranberry derived products in the prevention of UTIs in women with recurrent UTIs. The writer developed the following PICOT question to conduct the research: In women who experience recurrent urinary tract infections (UTIs), how does the use of cranberry derived products effect the number of diagnosed urinary tract infections compared to those women who do not use cranberry derived products in a twelve month period?

Preventing Urinary Tract Infections

“Urinary tract infections (UTIs) refer to the presence of a certain threshold number of bacteria in the urine (usually > 105/mL)” (Occhipinti, Germano, & Maffei, 2016). UTIs are one of the most prevalent infections requiring outpatient treatment (Jepson, Williams, & Craig, 2012). “Complications resulting from persistent and repeated infections necessitate well over one million hospital admissions annually in the U.S.” (Jepson, Williams, & Craig, 2012). Certain sub-populations are at an increased risk of developing urinary tract infections including infants, pregnant women, elderly women, and individuals with urethral catheters (Jepson, Williams, & Craig, 2012). UTIs are 50% more common in women than men (Jepson, Williams, & Craig, 2012).

Cranberry derived products (juices, syrups, tablets, capsules, etc.) have been commonly used for several years to prevent urinary tract infections. Historically, it was thought that the acid in the fruit created a bacteriostatic environment in the urine, not allowing bacteria to adhere to the bladder wall. However, recently, “a group of proanthocyanidins (PACs) with A-type linkages (PAC-A) was isolated from cranberries and shown to exhibit bacterial antiadhesion activity against both antibiotic-susceptible and -resistant strains of uropathogenic bacteria” (Occhipinti, Germano, & Maffei, 2016). “A randomized controlled trial (RCT) evaluating the dosage effect of cranberry found that to achieve a bacterial anti-adhesion effect in urine, 36 mg of cranberry PAC equivalents/d is effective, but 72 mg may offer better protection” (Jepson, Williams, & Craig, 2012). In order to keep the anti-adhesion activity high in the urinary tract, cranberry derived products should be taken both in the mo
