Evidence. What is it?A - Using Google to find answers
B - Making decisions based on what has worked in the past
C - Using current research to support decision
making
D - I have no idea

“Evidence-based health care is the “intentional use of current best evidence in making decisions about the care of individual patients or the delivery of health services.” (Cochrane)

How do we find evidence anyway?
The Literature Review!
![Page 5: Research Basics for Clerks & Residents](https://reader036.vdocuments.mx/reader036/viewer/2022081519/558953d3d8b42af20b8b46f9/html5/thumbnails/5.jpg)
Core Skills demonstrated by the Literature Review:
•Research and Subject Expertise: You can locate and have read the full range of accredited sources relevant to your topic.
•Critical Analysis: You can summarize, synthesize and evaluate those sources within a coherent, organized document.

Overview of Writing Steps:
1. Take summary notes on each article, synthesize and evaluate.
2. Organize the literature review, keeping in mind your thesis and how the structure will prepare the way for your research.
3. Write the first draft.4. Revise for tone, analysis, clarity, writing
style.

Research Cycle: Prepare
• Define your topic (though doing some research will help you tighten your focus, so be flexible)
• Develop search terms
• Identify key resources
![Page 9: Research Basics for Clerks & Residents](https://reader036.vdocuments.mx/reader036/viewer/2022081519/558953d3d8b42af20b8b46f9/html5/thumbnails/9.jpg)
Define your topic• Read background information
– Reference materials– Websites– Textbooks
• Talk to your supervisor, classmates, and colleagues
• Be flexible

Developing search termsTopic: Use and preservation of indigenous knowledge in First Nations’ communities in Northern British Columbia
![Page 11: Research Basics for Clerks & Residents](https://reader036.vdocuments.mx/reader036/viewer/2022081519/558953d3d8b42af20b8b46f9/html5/thumbnails/11.jpg)
Developing search terms• Indigenous knowledge:
• Traditional knowledge• Local knowledge• Aboriginal knowledge
• First Nations: • Aboriginal • Indigenous• Native• “Indian”
To find other search terms:
• Think about different variations of the words/phrases
• Search online• Use a thesaurus

Scan and Review
Helpful Tip: Check the bibliography of useful articles and resources to find other resources
• Take breaks in the search process to review your progress
• Ask: Do I have enough information?• You will need to read A LOT• You may have to go back for more research after
you’ve started writing
