1. Identifying the evidence Phil Hannaford NHS Grampian Chair of Primary Care

2. Evidence based medicine “The conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence-based medicine requires the integration of individual clinical expertise with the best available external clinical evidence from systematic research and our patient’s unique values and circumstances.” Centre for EBM

3. Some reasons for EBM Increasing demand for high quality, effective and efficient care Continuous improvements in diagnosis, treatment and prevention of disease or unwanted health- related outcomes Recognition that clinicians rarely spend more than 30 minutes a week keeping up-to-date

4. Clinicians (and managers) frequently have information overload

5. Traditional information sources often have problems Textbooks Experts Narrative reviews Editorials Medical journals –out of date –wrong or selective –overwhelming volume / irrelevant information

6. We need new ways of getting and handling information

7. Approach depends on your information need 1.Identify and appraise original article(s) 2.Identify and appraise summary, review articles 3.Seek clinical guidance 4.Get regular relevant new information

19. 2. Identify and appraise summary, review articles Traditional narrative review

20. 2. Identify and appraise summary, review articles Traditional narrative review Systematic review /meta-analysis

If the results of the studies can be combined and summarized statistically, the systematic review is called a Meta-analysis.
