Week 1: What is EBP Flashcards
Define EBP
EBP is conscientious, explicit and Judicious use of current best evidence in making decisions about the care of individual patients.
What is the purpose of EBP?
To assist in making an informed clinical decision.
5 steps that make up the EBP process.
- Ask
- Acquire / Access
- Appraise
- Apply
- Audit.

Outcomes
What sources should EBP involve?
- Clinical expertise
- Best Research evidence
- Practise context
- Patient centered.
What does clinical expertise mean?
The knowledge gained from practical experience and activities relevant to the specific field of health.
Practise context?
The information should be gathered relevant to the branch of the health that the clinician trying to answer the question is excelled in.
Patient centered
The research should be done by gathering information relevant to the individual patient and the patients needs and wishes.
ASK ??
Ask an answerable question.
The information required is translated into an answerable question. This is done using PICO question.

Best research evidence
The information gathered from research should be from the best available study designs relevant to the question required to be answered.
ACQUIRE? Or ACCESS?
Using the answerable question made, a systematic search strategy is developed and evidence is located. I.e., we try to gather as much information as possible.
APPRAISE??
Ones the available evidence , study is gathered, it is important to make sure that the evidence gathered is of good quality and the best available. The quality check of the evidence is done using checklists that are used depending on the type of question.
APPLY
After making sure that the best available resource is gathered, a plan is made to apply the gathered information to the patient.
AUDIT
Review the first 4 steps as to what was done best and what needs to be done better the next time.
Why is EBP important?
- to make informed decision about care for each patient.
- address any concerns by the patient
- substantiate information bought in by the patient
- substantiate why a particular intervention is done on a particular patient.
- to use the best available evidence to find an answer.
Scope of EBP
EBP’s scope is wide. Not just within health but education, engineering, conservation, sport and so on.
While appraising the evidence, what are the three aspects that we focus on? .
- Internal validity
- Impact
- External validity.
Internal validity?
Checking if the evidence is trustworthy. was the study conducted ethically, and methodologically. Are the results correct or assumed? How much can you trust the results. If the study’s was not conducted properly and falsified, then the results a does not reflect eh actual population.
Impact?
If the study is internally valid, we look at the clinical importance of the evidence provided. Was the study size big enough that the results could be reflecting the results in the true population .
Applicability / external validity.
If the study is internally valid and clinical y important , is the evidence applicable to your patient?
