The process of Evidence-Based Practice (EBP) can be broken up into 5 phases, called the 5 A's of EBP. Those phases are as follows.
Step 1: assess the patient or the problem in front of you.
Step 2: ask or identify the most important question, using the most appropriate question framework.
Step 3: acquire the best available evidence to help you answer the question.
Step 4: appraise the evidence to decide if it's applicable to your patient or scenario.
Step 5: apply the solution to your patient or problem.
EBP is a never-ending process, whether you're using it for patient-care or systems improvement. Each problem or situation should be reassessed to make sure the solution still works and to make sure new problems are addressed.
