2015-2016 2 THE FLORIDA STATE UNIVERSITY COLLEGE OF MEDICINE EBM A Multi-Step Process The patient 1. Start with the patient -- a clinical problem or question arises out of the care of the patient The question 2. Construct a well built clinical question derived from the case The resource 3. Select the appropriate resource(s) and conduct a search The evaluation 4. Appraise that evidence for its validity (closeness to the truth) and applicability (usefulness in clinical practice) The patient

5. Return to the patient -- integrate that evidence with clinical expertise, patient preferences and apply it to practice Self-evaluation 6. Evaluate your performance with patient & process 2015-2016 3 THE FLORIDA STATE UNIVERSITY COLLEGE OF MEDICINE The Question 2.

How common is it? Is it usually aggressive and rapidly fatal? How can it be treated surgery, chemotherapy, radiation? What about family history what about his sons risk? Etc.

What are my choices to best care for THIS patient? What is the best way to diagnose and treat this patient? What are the patients preferences and special considerations? Use PICO format for Foreground questions THE FLORIDA STATE UNIVERSITY COLLEGE OF MEDICINE Constructing A Clinical Question P I C O patient intervention comparison

outcome Who? What? Alternative Intervention? Outcomes How would I describe a group of patients similar to this particular patient? 2015-2016 Which treatment, test or other intervention? What is the Compared to what patient oriented other treatment, test, outcome better

or perhaps compared prognosis? to doing nothing Higher rate of cure? Etc.? 7 THE FLORIDA STATE UNIVERSITY COLLEGE OF MEDICINE Examples P Kids with acute otitis media -2-4 y/o I Antibiotics Adult with microhematuria IVP Adult patients <70 TIA Healthy adolescents 2015-2016
