"The integration of individual clinical expertise with the best available clinical evidence from systematic research."

The process of systematically finding, appraising, and using contemporaneous research findings as the basis for clinical decisions. Evidence-based medicine (EBM) follows four steps: formulate a clear clinical questions from a patient's problem; search the literature for relevant clinical articles; evaluate (critically appraise) the evidence for its validity and usefulness; implement useful findings in clinical practice.

Step 1: Assess your patient and determine the pertinent issues. You may be looking for evidence about therapy options, prognosis or diagnostic techniques.

Step 2: Ask a clinical question. Use the PICO model to formulate a clear and concise clinical question.

Step 3: Acquire the best evidence. Search the appropriate databases and resources to find the best evidence.

Step 4: Appraise the evidence. Determine whether the information you found is relevant, valid and applicable to your patient.

Step 5: Apply the evidence to your patient. Ensure that the evidence and recommendations meet your patient's values and expectations.
