Stepping up to Evidence Based Practice - Ideas into Action 3

Finding the Evidence

QAH HospitalPortsmouth Hospitals NHS Trust

Objectives

Develop your idea for action and turn it into a clearly defined question

Discuss strategies to identify the evidence and structure any search

Identify resources for finding the evidence Have a go at accessing some of the electronic resources

What do I need for this session:– Your/your team’s idea for action– Access to a computer/Library website– Worksheet 3


Ideas into action…

Let’s just think about your care idea or issue that you want to explore..

What is it? Whose idea was it? How did it come about? How do you know it is an issue or

problem that needs to be addressed?


Developing your idea/question?

Be really clear about what you want to explore. Brainstorm your ideas with colleagues? How does it fit with the values of your team? Can you gain some consensus? Does it sound like a feasible idea – best to start with small

successes? Can you frame it in a specific question e.g. how effective is

manuka honey in healing leg ulcers?

Undertake exercise 1 worksheet 3


Using PICOT

The acronym PICOT is a tool to help you refine and identify the question you want to address.

Quantitative– Population– Intervention– Comparison– Outcome– Time

e.g. Does education about alcohol (intervention) reduced alcohol consumption (outcome) in patients with liver disease (population) admitted to hospital (comparison) after transplant (time)

Qualitative– Population– Issue– Context– Outcome– Time

e.g. Why (outcome) do patients with liver disease (population) admitted to hospital (context) after transplant (time) continue to consume alcohol (issue)


Refining your question….

Try writing out your question or care issue that you want to explore using the PICOT process (exercise 2 worksheet 3).

Time may or may not be relevant – you don’t have to use it.

Has your question changed?

Does it feel clearer or more focussed?


Evidence and audit?

Is the problem/care issue you have identified a result of audit?

Do you need to audit the aspect of care before making any changes?

Do you have any other evaluation e.g. feedback from patients, other members of the multi-professional team?

If you plan to audit… use an already validated tool if possible.

Does the audit also reflect the need for change?


Finding the evidence..

Do you know if the evidence exists already?– Is it linked to a new policy or national guideline?– Is it the output of someone’s EBP project– Can you trust this evidence?

Access NHS Evidence http://www.evidence.nhs.uk (at the end of this session) and try a small investigatory search to begin with

Think about the search terms. How clear are they? Do they focus on the right thing? Do you get the results you want?

Decide which databases you want to search (Library will support)

Firm up your key terms/search terms – look at the key words used in highly relevant papers to help with this


Find the evidence..

Once you have a clearly framed question and your key terms..

Either ask the Library outreach team to undertake a search for you…

Or book a session now to search the evidence with library support…

Or if you are confident in your search skills, undertake a systematic search of the databases

Remember to think about inclusion/exclusion criteria e.g. studies over 10 years old, studies of adults etc.


Top tips…

It is time-consuming and so schedule in time Get help from Library staff (or colleagues) Remember you can access all the Library resources from

home Develop a comprehensive and systematic approach to

your search – keep a record Don’t just rely on electronic searching of databases Read abstracts to decide if useful NHS Evidence is a useful resource and depending on

your topic, also try starting with Cochrane Library/NICE Don’t get distracted (off topic) and remember to call it a

day!


Finding the evidence..


Hierarchy of evidence..

Systematic reviews,Meta-analysis

Randomised controlled trials

Cohort, case controlled studies

Surveys

Case reports

Qualitative studies

Expert opinion

Anecdotal opinion Sackett et al, 1996

Highest

Lowest


Using the hierarchy of evidence…

It can be misleading – geared towards medicine and treatment intervention

If you can find a systematic review/meta-analysis which helps answer your question – great!

Also try Cochrane database/library, NICE guidelines and National Service Frameworks

Any local policy should be underpinned by evidence – if not evident, contact the author of the policy who may be able to help

In some topics, qualitative research may be more appropriate and be “higher up” the hierarchy!


Cannot find much or any evidence?

Search outside of the usual databases Look at similar topics/issues in different populations. Try cross-referencing e.g. finding a very good paper,

policy and looking at the reference list. Author searching – using the names of experts in the field


Steps of the search (summary)..

Define/refine the question Identify key terms – and inclusion/exclusion criteria Undertake search:

– Using appropriate databases

– Using a variety of strategies

– Seeking guidance/support as required Record search strategy Manage and store literature effectively (make use of the

tools to save searches electronically, print off hard copies as you need)


Making a start (exercise 3, worksheet 3)..

Go to the library (or a desk with computer access)

Access http://www.evidence.nhs.uk via the PHT intranet/Library

Undertake a preliminary search of your topic and begin to identify what your key search terms might be

Do you know the code to access the electronic journals (this is NOT your usual PHT login or your Athens login)? To obtain it, you must either visit or call the Library (you will need your library card number).
