This page will provide you with links to the different databases and AI Tools that you can use in your quest to locate the knowledge sources to answer your clinical question. We advise that you watch the two videos in this course to guide you in navigating all these tools.
Introduction[edit | edit source]
The second step in the evidence based practice model involves finding the knowledge sources. This corresponds to the Acquire component of the 5 A’s.[1]
Locating the best evidence that is related to the PICO clinical question can be a challenge. There is a vast amount of information available on the internet but clinicians face challenges such as knowledge about which sources are reliable[2], the time it takes to find the relevant information[2], deciding which information is of high-quality[2] and also doubt that a selected resource or search will provide an answer. [3]
Primary versus Secondary Research[edit | edit source]
Primary research refers to a single research study conducted by a researcher or group of researchers which has been written up, whereas secondary research refers to synthesised findings and is usually in the form of a literature review. Secondary research such as a literature review usually reviews multiple primary research studies and summarises the research papers.[4]
Database Searching 101[edit | edit source]
- Start with a clearly defined clinical question using the PICOT format.[5]
- Refresh your memory of how to formulate your clinical question: Evidence Based Practice and Patient Needs
- Organise your keywords for your search according to the PICOT Table
- Use synonyms, related terms and/or truncation to broaden your search
- find relevant synonyms by searching online medical dictionaries or using the MeSH (Medical Subject Headings) function in PubMed[6]
- truncation - adding the first part of a keyword usually followed by a asterisk (*) (Note: databases can have different truncation symbols, so check the help service of the database if you are uncertain). This way any variant spelling of the word is searched for example: rehabilit* will find rehabilitate; rehabilitates, rehabilitation; rehabilitated
- Use Boolean logical operators - AND/OR
- using Boolean operators leads to more focused results[4]
- AND - if all the search terms should be present in each article (different concepts and to be more specific)
- OR - if any of the search terms should be present in each article (same concept)

Where to Find Full Text Papers[edit | edit source]
Below are suggestions on ways to find full text papers:
- Follow the link on the platform of the database that you searched
- Go straight to the journal or publisher’s website
- University library members – make sure you are logged into the university’s online library
- Google an article's citation details
- E-mail the corresponding author
- Search for the author’s websites
- Request paper from the author on Research Gate or Academia.edu
- Find out if your university library has the option of inter-library loans
Find a method that works best for you and save the articles that you found and downloaded in a folder. Name them so that you can easily find a specific article that you are looking for.
