Principles of EBP Flashcards
Define evidence based practice?
The conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient
Systematically reviewing, appraising, and using clinical research findings to aid the delivery of optimum clinical care to patients
Define satisficing
Being satisfied with information you can readily summon, sacrificing quality for convenience when providing drug information
What are the 5 steps of EBP?
1) Converting the need for information into answerable questions
2) Collecting evidence to answer questions
3) Critically appraising evidence for validity, impact, and applicability
4) Acting on evidence (making decisions by integrating evidence with your clinical expertise and patient value)
5) Evaluate your effectiveness and efficacy and seek ways to improve
What are the 5 A’s that summarise the principles of EBP?
Ask a question
Access the evidence
Appraise the evidence found
Apply the information
Audit
What are the two strongest form of evidence?
1) Evidence with at least one systematic review
2) at least one properly designed randomised control trial
What are the intermediately strong forms of evidence?
3) Evidence from well designed trials without randomisation
4) Evidence from well designed non-experimental studies
What is the weakest form of evidence?
5) Opinion based on clinical evidence
How is the RAMmBO acronym used to critically appraise a study?
Is the study
(R)epresentative of your patients under question
Is the (A)llocation of intervention –> randomised? comparable groups?
(M)aintenance = course of trial –> are patient’s treated equally? are they compliant?
Study outcome ((m)easurement) = (B)lind subjective? (O)bjective?
What does the application of EBP do?
Effective care
Improving patient outcomes
Professional accountability
Efficient use and minimising wastage
Responsible use of scarce healthcare resources
Can influence policy, purchasing and management decisions in health and other sectors
What are the limitations to EBP?
Heavily reliant on quantitative research = role of qualitative research in EBP is also important
Limited availability of research evidence base = some areas of healthcare have limited research
Research evidence adequately capturing the complexity and rapidly evolving professional practice
The nature of evidence = alternate suggestions such as knowledge-based practice and information-based practice
What does PICO stand for?

Intervention
Comparison
Outcome
What is PICO used for?
Used for formulating/asking answerable clinical questions
