3 INTRODUCTION/ DEFINITION A literature review (LR) can be defined as a piece of writing that supports, evaluates and critiques your research topic. It involves the use of most relevant work in the subject area. A LR is a form of essay writing, which is non opinionated nor argumentative. It should not only demonstrate a good knowledge of relevant strands of literature A LR may constitute an essential chapter of a thesis or dissertation.

4 INTRODUCTION (cont’d) It should also show a critical assessment of literature with up to date references. Although a summary of what you have read is contained in an LR, it is well beyond summarizing each article you have reviewed. It involves extensive reading, analyzing available literature, critical appraisal of different works, And then relating these researches to your own work.

5 AIMS A good LR aims to accomplish the following: Define a research problem Review the critical points of current knowledge. Review theoretical and methodological contributions to a particular topic.

6 LITERATURE SEARCH Your search can be done manually or through electronic means. Manual search can be done in, The college library, Central medical library, University library, FNPHY library. For electronic search, there are different search engines, E.g. Google, Yahoo. There are also different websites that you don’t have to subscribe to for full texts.

7 LITERATURE SEARCH (cont’d) From search engine go to PUBMED. Best option is to go through HINARI. (You can get more full journals this way). Type in key words from topic or authors. Going to related links can be helpful. Download relevant articles. And then save on computer.

8 SOURCES OF MATERIALS Useful sources of literature include Published articles, Abstracts of published articles, Dissertations, Conference presentations.

9 SOURCES OF MATERIALS Other sources include, Textbooks. Use is not advisable. WHY? May be outdated, They don’t provide references, Usually reflects writer’s bias. Unpublished work from the internet, (‘JUNK’). WHY? They are unscientific, opinionated, lack references.

11 THE WRITE UP Your LR may be organized in 2 major ways: Thematic (topical), Chronological. Others include, Trend/pattern of events, Publication chronology, Methodological, A blend/combination of the above.

12 WRITE UP (cont’d) In thematic approach, the LR focuses on the topic/issues. Each segment represents a part of a larger issue. In chronological approach, it focuses on the chronological progression of the field, the literature or the idea, that is necessary to understand the LR. Clarify the number of words before you write. Organize your thoughts and gathered information, by creating an outline.

13 WRITE UP (cont’d) You may refer to previous dissertations. Make sure you develop a coherent essay. Be selective. Make use of only relevant points.

14 WRITE UP (cont’d) Don’t forget to include your references as you write along. Site references in uniform style. The introduction should usher in the topic. It may contain the definitions of key terms in the topic, historical background, a valid thesis. Explain your line of argument (or thesis). Include any other relevant information that you deem fit, as it relates to your topic.

15 WRITE UP (cont’d) The body of the LR should address issues like Definition of the problem Prevalence of the problem, internationally and locally. Etiology/ risk factors/ correlates and pattern or distribution. Detection and diagnosis

16 WRITE UP (cont’d) Treatment modalities. Complications And outcome. And then the conclusion which is a summary of your LR.

17 WRITE UP (cont’d) At the end of the day, a well written LR should have answered certain key questions, What is the nature of the problem? Is it of significant public health importance? What is the extent or magnitude of the problem. What are the effects of the problem on public health?

24 GUIDELINES Step 3: Analyze the literature. Have an overview of articles, focus more on abstracts, introductions and conclusions. Group articles into categories; (into topics and sub topics, chronologically). Take notes by defining key terms, note key statistics, note emphasis, strengths and weaknesses, identify major gaps, identify major trends and patterns, identify relationships among studies, evaluate references for currency and coverage, remain focused.

25 GUIDELINES Step 4: Summarize the literature. This may be done in a tabular form. You may also summarize manually in a jotter. For e.g., you may summarize, Definitions of key terms and concepts, Research methods, Summary of research findings.
