Literature Review
Before developing a new drug, pharmaceutical companies research products that are currently on the market. In their research process, corporations may ask questions such as, “What are current health needs, and how could a new drug address these needs differently than drugs that are currently available?” or “What new innovations can counteract certain diseases?” Before fully refining the focus of any research, individuals should attempt to determine the current state of affairs in their area of interest.
One of the most common ways to accomplish this is to conduct a literature review. A literature review allows one to take a “snapshot” of the established knowledge in a particular area. Using this snapshot, researchers can determine the merit of their research questions and how they may need to modify their research goals. For this part of your Evaluation Project, you create a Literature Review Summary Table and synthesize the current state of research surrounding the PICO question you developed.
To prepare:
- Review the Week 6 Learning Resources on procedures for conducting a literature review.
- Using your approved PICO question and relevant search terms, locate a minimum of five full-text research articles to use in your literature review (Articles must be scholarly and peer-reviewed and no older than 5 years old) See Attached PDF files
- Read through the articles carefully. Eliminate studies that are not appropriate, and add others to your list as needed. Although you may include more, you are expected to include a minimum of five appropriate articles.
To complete Part 3 of the Evaluation Project:
By Day Thursday 1/19/17
1) Complete a Literature Review Protocol Summary Table using the template in this week’s Learning Resources. (See attached PDF file below)
2) Write a 1-page literature review that synthesizes the findings in the literature related to the question you developed.
3) Explain how the literature demonstrates the significance of your PICO question topic. My PICO question is: Does implementing a new unified acute and ambulatory Electronic Health Record (EHR) system within the hospital, compared to when they are not used improve the quality of healthcare for the patients through documentation?
4) Describe original conclusions that you derived from the evidence you gathered. Support your synthesis and conclusions using evidence from the literature.
P.S. Include an introduction and a summary. The introduction must end with a purpose statement (e.g. “the purpose of this paper is …) Cite at least 3 references from the list below in addition of all references from the Literature Table.
