NURS 6431: Evaluation Methods for Health Information Technology | Week 6

Dr. Peter Roget developed the first thesaurus as a personal guide to help improve his vocabulary. It was not until he was 73 years old that he published the first edition of what is now known as Roget’s Thesaurus. The original manuscript contained a list of only 1,500 words. It has now expanded to hundreds of thousands of words, digital versions, foreign language versions, and even a visual version that creates a mind map of your words! Because of the extensive variety of words it contains, a thesaurus is a useful tool for selecting the best key words when searching the literature on a specific topic.

This week, you examine strategies for searching the literature to identify relevant, evidence-based practices for your Evaluation Project. You also begin to develop a synthesis of the literature to inform your Evaluation Project.

Learning Objectives

Students will:

• Translate a PICO question into criteria for searching the literature
• Formulate strategies for literature searches
• Utilize appropriate search resources for identifying relevant information*
• Develop a synthesis of literature*

* The Assignment related to this Learning Objective is introduced this week and submitted in Week 8.

Discussion: Identifying Relevant Literature Resources

Searching for relevant literature on a given topic can sometimes be a frustrating process. In some instances, you might have trouble finding anything at all of relevance, whereas in other cases, you might find overwhelming amounts of potential resources and have to determine which is the most relevant to your search. Literature searches can be very rewarding when you find a perfect evidence-based article or research piece that precisely addresses your area of concern.

For this Discussion, you focus on conducting literature reviews and on locating and identifying the most relevant current literature.

To prepare:

• Review this week’s Learning Resources on conducting a literature review.
• Go to the Walden Library website, and explore tools for generating search terms.
• With your PICO question in mind (regardless of approval status), identify at least 10 different search terms you could use in your literature search.
• Reflect on how to assess the relevance of specific research to your PICO question.
• Consider techniques for performing alternate types of searches if few or no resources are located.

By Day 3

Post your PICO question (first draft if not yet approved) and the 10 search terms you plan to use in your literature search. Describe one of the literature search tools you identified in the Walden Library and where it is located. Explain how you can assess the relevance of the research you review. Finally, describe strategies for performing alternate types of searches if initial searches do not yield sufficient resources.

By Day 6

Respond to at least two of your colleagues on two different days. Review peers’ search terms, and offer alternative or additional terms as appropriate. Provide an additional technique for finding relevant information.
