2. Outcomes
Students will be able to:
• Locate, access and manage information through the UWA
OneSearch Library catalogue;
• Understand the Hierarchy of Evidence and have some tools
to assist you in appraising different levels of evidence;
• Locate expert help guides in dentistry and to assist in
finding evidence based resources and methodologies
6. A closer look at OneSearch…
Step 1: Sign in
Signing in provides you with more content, it is easier to access
our licensed content and you can utilise the full functionality of
OneSearch including a personal e-Shelf and ‘My Library Account’
7. Activity
• Go to the library home
page
• Find Medical Expert
Guides/Dentistry
• Login to OneSearch
8. Viewing your e-Shelf
This is a permanent personal area where you can save
individual items, save your search queries and view
current loans (Find “Save Query” at bottom of limits)
3 e-Shelf Tabs
9. Managing your loans in “My Library Account”
This is where you can see what you currently have on loan,
any items you have requested and other information about
your borrowings.
10. Step 2: Conduct your search
Use the Advanced Search Box for more control
over your search strategy.
11. Step 3: Refine your search
Use limits in the LH column to refine your search
12. Step 4: Access information
Click on the
STAR to
colour it in
and place an
item on your
eShelf
Database platform options
13. Step 4: Access information
Provided by UWA
DOSS Dentistry Database on the EBSCO platform
14. Activity
• Construct a search of two dental concepts of interest to you
• Use some of the limits available to further refine your search
results .
• Check the details tab and then save a few of the ones that
look relevant to you into your eShelf
• Save a query into your eShelf
• Jump out to a database platforms
16. Step 5: Follow good leads
The Times Cited tab appears for articles that have links to Web of
Science and Scopus citation databases.
The View Citation link opens in a new window and takes you directly to the citation
database.
17. When you click on View Citation link, it takes you to the citation
database (Scopus in this article)
20. The purpose of a literature review is to identify the
existing body of research that has addressed a
problem and clarify the gaps in knowledge that
require further research. 1
The term levels of evidence refers to what degree
that information can be trusted. 1

Levels of Evidence
24. Key Players: Australia
JBI Connect
Produce systematic reviews and
best practice guidelines.
http://joannabriggs.org/research/critical-appraisal-tools.html
27. Evidence-based guidelines
& summaries
• Developed by synthesising the highest level of
evidence available on treatment choices
• Guidelines provide recommendations
supported by that evidence
• May take into account resources and practices
relevant to the organisation
• Concise and clinically relevant
28. Where do I find evidence?
• PubMed/MEDLINE
and Embase
• Cochrane/JBI
• DOSS – Dentistry
• TRIP/OvidMD
• BMJ Best Practice
• ClinicalKey
• UpToDate
• ETG Complete

Welcome. My name is.. And this is..
This first hour will be spent given a very general introduction the UWA Library catalogue…
Can I just have a quick show of hands who is new to the University?
Who has completed their undergraduate degree here and feels they are already familiar with library services?
Great.. Looks like there will be enough people to provide any help to those that are new….and hopefully we will provide some new information to those who have been here for a while.
For those of you who are new here, I should mention that the Medical and Dental Library has been closed until September 2017, due to the refurbishment project. Although the building will be closed, alternative arrangements are in place to access collections and services. You can borrow items from the third Floor of the Barry J Marshall Library or offsite storage. Also you can find us and access to High Demand Collection at the EDFAA library.
OneSearch is where you can access all the UWA information resources.
As name implies.. It is the one place you can find all of the information resources we purchase and subscribe to on your behalf.
It includes all ……book & journal titles, (print or online), often will search down to the article level within journals and across a large number of specialist databases. Also the place you will find any essential readings in our system called CMO.
So it’s really important that you can find it.. Let’s all go there now…
From the menu item on the UWA home page you will find a link to the library home page.
Can I have a show of hands who has been here before?
Possibly go to this page and point out a few of the services of specific interest…
Ability to book a group study room in any of our six libraries
Opening hours and computer availability to help you decide which library to study in
Quick links to other important services and information for you..(we will be looking at Expert Help Guides soon)
The Expert Guides can be particularly useful if you are new to UWA and/or unsure of how to find resources specifically for Dentistry.
Go onto live site and demonstrate, going to Dentistry Lib Guide
This page shows the Advanced search box in OneSearch (you can see that there are different tabs for CMO ?? and Exam papers)
This Advanced search page allows you to build a fuller search joining your key concepts with AND or OR.
You can also see across the top some of the links to other collections, services or information.
It is really important to get into the habit of signing in to OneSearch, this will provide you with fuller access to more full text articles and collections. You can see the sign in option from the “home page” and from this Advanced search screen that we got to from the home page.
Notice at the moment it says “Guest” this means you are not logged in. You can still save things but they won’t be there for you when you come back again.
When you click on the OneSearch login you will get this choice of login options? Which one should you choose?
The login is your pheme.. That is your student number and pheme password.
Can you please go to the UWA Library home page for me now.. And login now for me?
First have a go at finding the Expert Guides, then come back and sign into OneSearch for me.
Both of us walking around the room to assist if necessary.
Now that you are signed in you can see that your name will appear besides the e-shelf area. Clicking on e-shelf opens up this personal area organised into 3 tabs: (go to live demonstration)
You have the eShelf itself which is where you can save individual items of interest to you. You can see you can organise them into folders as well much like a windows environment. There is also an option for pushing them to Endnote which we will use.
The queries tab is where you can save specific searches you have constructed that work well for your topic.
The My Library shows books you currently have on loan and a history.
Working from the advanced search box, you can begin to construct your search by thinking of your key search concepts and joining them together with AND - this will make sure you return results that relate to both concepts. I have used the inverted commas here to increase the likelihood of returning results that list both words together.
We will be going through search strategies and the use of the AND or OR operator in more detail shortly.
OneSearch offers a number of ways you can subsequently refine or filter your search results.
Here we have reduced our initial search from almost 2000 to 200 results by refining by “dental plaque” as a subject category and limiting to more recent publications from 2008 onwards.
Have a go now at undertaking a search in the Advance box and then refining your topic.. Haleh and I will walk around and assist you.
You can sometimes get a lot of information about an article from it’s summary abstract. Sometimes these are also pulled into OneSearch and available under the details tab – this will help you to decide if the article is relevant to your research.
If the article is available online you should see a “View Online” tab and from here you can jump out to the database platform that has this article. Note in this instance it is available from 2 different database platforms – just choose one.
Also note that the first example has a blank star and the second is coloured in. This is how you get an item record onto your OneSearch eShelf – just click on it with your mouse cursor to colour it in and you will then find it on your shelf.
Here is the article located on the Ebsco Host Database Platform within the Dentistry and Oral Sciences database. You can see that you are logged in as a UWA user.
You can see the subject index terms used in this database, indicating further ways you can search this particular database on dentistry topics.
You can also see where you can get access to the full text of the article.
All database platforms will be slightly different and it is just a matter of getting use to navigating your way around it.
Demonstrate LIVE finding a query search you have saved and ask them to save their search (show down the bottom of the limits)
Your turn.. Construct a search of two dental concepts of interest to you… use some of the limits available to further refine your search results. See if you can save some of these - the ones that look relevant to you - into your eShelf..
Demonstrate LIVE finding a query search you have saved and ask them to save their search (show down the bottom of the limits)
Also check you are comfortable jumping out to database platforms.. If the first one does not work try the second.. Look for the tell tail signs you are in a UWA provided resource and can access thee full text.
The Citations button enables you to quickly find articles that the author has cited in writing their article – commonly known as references (but not complete - only one result in this instance).
The Cited by button – continues to explore for each of the referenced articles identified – any further citation links.
NOTE: Not complete.. Databases such as Scopus and Web of Science do this better.
to quickly find articles that have cited this article.
Citation searching is a useful way to explore a topic by using an article of interest as a starting point, find articles that is has cited (References used), and see how the scholarly conversation has progressed by seeing articles that have subsequently cited it.
From here you can investigate further the details of other articles related to this topic, and key authors.
Use the Find It at UWA tabs to see if we have access to the full text.
A range of ways you can analyse results.
Remember, as you find resources of importance to your research area you can save them in your eShelf so that you are ready to send them out to Endnote and then further manage them as you begin to write up your assignment.
You could also save to your eShelf specific readings organised for you by your unit coordinator which you may find within your unit code within the CMO tab.
Homework.. To add more content to your eShelf.. So we can push these out to Endnote in our Tuesday session.
There is so much medical literature published you need to know how it is organised and the quickest way to find the information you need.
In Medical research it is particularly important to you are familiar with notions of evidenced based practice – that you base your practice decisions on the most up to date and high quality research on the population focus group you are working with in order to determine the best treatment.
Click link to OneSearch record of this eBook (will need Pheme credentials to read it), also shows the Multiple Versions feature.
Show contents and discuss briefly use of ebook platforms and of bookshelf.
Look at contents.. Focus particularly on break down of how to assess different papers that evaluate particular studies and in particular systematic reviews and guidelines.
Ask if students are familiar systematic reviews and Evidence based guidelines (hands up) and then to discuss some of the differences between them? Ask for feedback on these?
Greenhalgh, Trisha. 2014. How to read a paper: the basics of evidence-based medicine. BMJ Books: Hoboken.)
“The term ‘level of evidence’ refers to what degree that information can be trusted based on study design”. (Greenhalgh 2014)
As you can see from this pyramid the higher the corroboration of different types of evidence, the higher it is on the hierarchy.
You will come across many different forms of the hierarchy as it is continually being contested and evolving – so you will have to get used to interpreting it at a critical level.
This is the pyramid at its most basic level.. With single studies being considered the least reliable, moving to systematic reviews that undertake a robust review of studies undertaken on specific interventions, through to evidence based guidelines.. (however need to question if these latter do belong at the top of the hierarchy – in trying to provide an overview of current best practice of a condition as a whole)
We don’t have access to decision support systems at this time. They are systems that directly link to patient records.
Do have a EBM Lib Guide that provides links to the resources we offer to support EBM.
The bottom layer of the main hierarchy – single studies – has its own hierarchy depending on the original type of study performed.
This is where – if you are doing your own literature search or systematic review of treatment/disease research for a specific cohort – you would need to critically assess the research/studies/case focus for their research vigour and relevance to your area of health and cohort.
For single studies RCT are considered the most robust and unbiased and they are often the focus on systematic reviews.
Here is a new revised pyramid, (Developed by Dr Murad and his team at the Evidence Based Practice Centre, Mayo Clinic in Rochester USA.)
to take into account the need to think critically about the design and development of individual studies – replacing a straight line with a wavy one to indicate that some research lower down the hierarchy may actually be better if designed better than RCTs. The separation of systematic reviews from the pyramid emphasises that they themselves are a filter through which evidence is viewed and also subject to critical review in their overall design and development
The proposed new evidence-based medicine pyramid. (A) The traditional pyramid. (B) Revising the pyramid: (1) lines separating the study designs become wavy (Grading of Recommendations Assessment, Development and Evaluation), (2) systematic reviews are ‘chopped off’ the pyramid. (C) The revised pyramid: systematic reviews are a lens through which evidence is viewed (applied).
One consideration in the evaluation of evidence is who has produced it and how good their methodology is. One of the key highly reputed players in Australia is The Joanna Briggs Institute who collaborate with Australian and international research institutes to produce systematic reviews and from these best practice guidelines available through their library JBI Connect.
They also produce methodology guides and software to support critical appraisal. This link is a good one for quick checklists on how to appraise different types of studies as well as systematic reviews.
Middle level: Systematic Reviews.
Systematic reviews analyse and appraise primary studies on the same question.
This is a simplified version of the process. (There are UWA as a well as a number of resources for this)
The final report will include their search strategies, keywords, subject headings. It is good to look at this to enhance your own learning.
Finding a systematic review on a topic can save you a lot of time.
A well structured systematic review will include the databases searched, search strategies used and a detailed analysis of studies included in the review – their quality and strengths.
One of the most robust and trusted producers of systematic reviews is Cochrane Collaboration.
The Cochrane Reviews (like JBI) also work in collaboration with International research bodies to produce systematic reviews and have a number of specialist resource databases such as their SR Database and database of Randomised control trials.
Like JBI they also produce and collate methodology reviews and critical appraisal of research tools which have been collated into a number of Handbooks.
This link is a good one for quick checklists on how to appraise different types of studies as well as systematic reviews.
The top levels
This section of the literature will become important later in your course when you begin clinical practice.
Can you trust the synthesis of the evidence that has been completed – who has been involved in it, how recent?
Is it comprehensive and based on appraised high level studies and systematic reviews or in providing a comprehensive overview of current best practice is it compromised.
