Definition of EBP
|
The conscientious, explicit, and judicious use of the current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research.
|
|
|
Steps in EBP (5A1S)
|
ASSESS the patient, ASK the question, ACQUIRE the evidence, APPRAISE the evidence, APPLY: talk to the patient, Self-evaluate (w/ patient)

(w/ patient)

Study types in health science in decreasing order of strength

|
Efficacy vs. effectiveness study
|
efficacy= what is the ideal, optimal treatment; effectiveness= Ax of current practices
|
|
|
Meta-analytic techniques: Effect size
|
Difference in gains between two groups, difference in post-test scores between two groups.
Small/ medium/large: r= 0.1, 0.3, 0.5; d/g= 0.2, 0.5, 0.8; ratio= 1.5, 2.5, 4.25 |
|
|
Meta-analytic techniques: Confidence interval
|
How accurate the effect size is in estimating effect size in wider population (can it be generalized). Narrow=higher accuracy.
Above 0 = significant at p=0.05 level in favour of Tx, Below 0= significant at p=0.05 level not in favour of Tx, Crosses 0= non-significant |
