THE DERIVATION OF EVIDENCE-BASED MEDICINE 1972 Archie Cochrane Conscientious, explicit, and judicious use of current best evidence in making decisions about individual patients. ~ Archie Cochrane Dacvid L. Sackett 1992 NHS 1993 Cochrane Collaboration

FIVE STEPS OF PRACTICE EVIDENCE-BASED MEDICINE Step 1: Converting the need for information (about prevention, diagnosis, prognosis, therapy, causation, etc.) into an answerable question. –PICO Step 2: Searching the best evidence with which to answer that question. Step 3: Critically appraising the evidence for its validity (closeness to the truth), impact (size of the effect), and applicability (usefulness in our clinical practice). Step 4: Integrating the evidence with our clinical expertise and patients’ unique biology, values and circumstances. Step 5: Evaluating our effectiveness and efficiency in executing steps 1-4 and seeking ways to improve them both for next time.

THE COCHRANE COLLABORATION Structure - established as an international organisation in 1993, registered as a charity in the U.K. Aim - to help people make well-informed decisions about health care. How - by preparing and maintaining, and promoting access to, systematic reviews of the effects of healthcare interventions. Publishing Output – The Cochrane Library Wiley publishes the Cochrane Library for the Cochrane Collaboration

The Cochrane Library is the single most reliable source for evidence on the effects of healthcare. WHAT IS THE COCHRANE LIBRARY Health care in the 21 st Century relies not only on individual medical skills, but also on the best information on the effectiveness of each intervention being accessible to practitioners, patients, and policy makers. This approach is sometimes known as “evidence- based medicine”. Website:

The Cochrane Library is a collection of 7 main databases and 1 additional databases that describe Cochrane as an organization. These are: 1.The Cochrane Database of Systematic Reviews (Cochrane Reviews) 2.Database of Abstracts of Reviews of Effects (DARE) 3.The Cochrane Central Register of Controlled Trials (CENTRAL) 4.The Cochrane Database of Methodology Reviews (Methodology Reviews) 5.The Cochrane Methodology Register (Methodology Register) 6.Health Technology Assessment Database (HTA) 7.NHS Economic Evaluation Database (NHS EED) 8.The Cochrane Collaboration and the Cochrane Collaborative Review Groups (About) WHAT IS THE COCHRANE LIBRARY?

The Cochrane Database of Systematic Reviews (Cochrane Reviews)

Reviews address clearly formulated questions such as ‘does fluoride help prevent tooth decay in children’ or ‘can antibiotics help in alleviating the symptoms of sore throat’. Comprehensive and explicit methods are used to track down, select and determine the quality of relevant research. This includes searches for unpublished and non-English records to provide as complete a picture as possible to try to answer the question considered. A diagrammatic analysis is also provided in the form of an odds-ratio (OR) diagram. These diagrams reveal, at a glance, whether a treatment is beneficial or not. What’s so important about it? The Cochrane Database of Systematic Reviews (Cochrane Reviews)

What magnitude of risk reduction when a patient with Coronary Heart Disease stops smoking? Does the use of hydrolysed formulas for infant feeding prevents allergy and food intolerance? Does having a friend for support present during labor and childbirth impact on a woman’s experience? People who quit smoking after a heart attack or cardiac surgery reduce their risk of death by at least one third. When babies are not exclusively breastfed, using hydrolysed infant formulas instead of ordinary cow's and soy milk formulas can reduce allergies in babies and children. Yes. Continuous support reduces a woman's likelihood of having pain medication, increases her satisfaction and chances for 'spontaneous' birth, and has no known risks. What sort of healthcare questions are addressed?
