Literature Search

A literature search is a common assignment in many college classes.There is a spcific way to do a literature search and Paper Masters can help teach you how it is done with valid academic resources. Have a professional academic research paper writer produce a custom literature search for you today or use the sample below on a Medical topic to help you frame your literature search.

What is a literature Search?

A literature Search pulls together the entire evidence search process from initial idea about a clinical issue to end result of evaluating studies that relate to the issue. The project showcases your ability to manage that process and report on each step. For example, in a medical paper, you will want to describe the search strategies used to locate evidence in Medline, CINAHL and Google Scholar on your PICO question and evaluate evidence according to criteria presented in the course. It is important that the paper outline your search so that it could be easily duplicated.

The PICO formatted clinical question has been building step by step with identification of population of interest. A clinical question about population of interest should be formatted according to PICO and reviewed in threaded discussion.

Shape Your Clinical Question in PICO Format

Your original clinical question and the specific rationale for its choice with an analysis of the question by the PICO components:

  1. Present your clinical question and shape it according to PICO format.
  2. Clinical question should relate to a patient population of interest to you. State why you chose this population and justify the relevance of the topic to nursing practice.


B. Search for Studies Relating to PICO Question Search Medline, CINAHL and Google Scholar for evidence relating to your PICO formatted question from A. above.

  1. Present the results of your search for evidence to answer the PICO formatted question in the following 3 venues:
    • Medline --
    • CINAHL --
    • Google Scholar –
  2. Include a thorough description of each step of the search strategy in each database together with a rationale for choice of search terms. The citations in these searches may primarily consist of abstracts and some citations may appear in all 3 databases.
  3. Use search strategies learned in this course either in the lessons or in the tutorials associated with each database.
  4. At no time should “full text” or “local holdings” be used as limits on the searches.
  5. Present 1 – 3 studies in each database; choose different articles in each database.
  6. In each database, search for systematic reviews on the topic. Include search strategies/terms to find systematic reviews if different from B. 2 above. Library may also be used as source for systematic reviews.
  7. Include total number of studies found about the clinical question (a systematic review counts as one article) in each database at conclusion of final search.

C. Analyze the 1 – 3 Studies Found in Each Database:

• Medline
• CINAHL
• Google Scholar
Include a complete description and analysis of each study produced by search in each database. The analysis of each article should include:
• Type of study – research, expert opinion, case study, etc
• Quantitative or qualitative?
• Population studied
• Setting for the study
• Kinds of interventions
• Summary of results (if available in the abstract)
• Relevance to PICO question
• Evaluate strength of evidence

D. Pick Two

• Select two articles (a systematic review counts as one article) from all of the results that you analyzed in that best address your PICO question.
• Justify the selection and state why these 2 studies constitute the best evidence. State any criteria of study validity used to select the 2 best articles.
• The two articles may contradict one another.

II. Presentation

  1. APA Format APA format must be followed for: running head, page margins, font, page numbers and reference citations. See APA tutorial in Institutional Resources.
  2. Standard English grammar and usage.
