This week we are comparing and contrasting epidemiological methods of research; case-control and cohort study methods. Select either the case-control or cohort study method and compare its features, the methodology, to a randomized controlled trial using the following questions. Please format, organize, your responses using each question below:
What is the fundamental difference between the method you have chosen (either the case-control or cohort method) and the randomized controlled trial?
What are the advantages and disadvantages of the study method you chose (case-control or cohort study)?
What are the characteristics of a correlational study?
Where does the method you chose (case-control or cohort study) fall on the research pyramid? What does where it is on the research pyramid mean?
Post your response to the DB. Your analysis should have in-text citations and utilize a scholarly voice with APA formatting.
Respond to a total of two posts: Either two (2) peer posts or a peer and faculty post (all faculty posts require a response), with a minimum of one paragraph of 4-5 sentences, on two (2) different days of the week. Your reply post should be specific to this week’s topic of epidemiological research methods and should integrate in-text citation(s).
Your reply post/s should integrate course content (such as course terminology) related to the study method as well as an integration of in-text citations along with a scholarly voice and APA formatting. The textbook may be utilized as a resource.

My PICOT question is In adult patients aged 65 years and above admitted to the ICU , does the implementation of strict hand hygiene and environmental cleaning protocols , compared to standard infection control measures, lead to a reduction in rates of HAIs within 12 months of ICU admission ?

ssessment Descriiption
While the implementation plan prepares students to apply their research to the problem or issue they have identified for their capstone project change proposal, the literature review enables students to map out and move into the active planning and development stages of the project.
A literature review analyzes how current research supports the PICOT, as well as identifies what is known and what is not known in the evidence. Students will use the PICOT question from the earlier “PICOT Question” template and information from the “Literature Evaluation Table” assignment to develop a review.
Using eight peer-reviewed articles, write 750-1,000-word review that includes the following sections:
Introduction section (including PICOT Question)
A summary of the purpose of the studies
A comparison of sample populations
A synthesis of the studies’ conclusions (when looking at all of the studies together, group the conclusions by themes )
A summary of the limitations of the studies
A conclusion section, incorporating recommendations for further research
You are required to cite a minimum of eight peer-reviewed articles to complete this assignment. Sources must be published within the past 5 years, appropriate for the assignment criteria, and relevant to nursing practice.
Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center.
