Evaluation #2: Literature search, critical appraisal, and implications for nursing practice.


Practical nurses are expected to conduct literature searches, critically appraise research articles, and discuss the implications for nursing practice. Therefore, this assignment has been developed for you to demonstrate your literature search skills, begin to appraise research articles, and think about the implications research may have for nursing practice.

Research begins with a question because we want to know why something happens and what to do about it. Think of an area of nursing you are interested in. 

Next, develop a clinical research question.  A well-constructed research question, that is relevant to a patient problem, will facilitate finding current evidence for use in practice. (Note that you cannot implement everything you read as there is a very complex process that has to occur first.) Use the PICO format to organize your question. The four elements of the PICO model are:

P: Patient/Problem

I: Intervention

C: Comparison 

O: Outcome


Conduct a computerized literature search to find an article that describes a research study on your chosen topic.  Read the research study and answer the following questions.  The initial 5 marks are for your research question and PICO.  The remaining 25 marks are divided into the sections of 1) literature search, 2) critical appraisal of the research study, and 3) the implications the research has for nursing practice. (The entire assignment is worth 30 marks, which is 15% of your final grade)
