As defined in 1996 by one of its founders, David Sackett, evidence-based medicine is “the integration of individual clinical expertise with external evidence from systematic studies.” Edward Whitney, MD, MSPH, notes that while the concept had been around for years, evidence-based medicine did not emerge as a formally recognized approach until the early 1990s when opinion leaders began making the case for it. Their position was strengthened when several widely accepted treatments, which were based on general medical and biological principles, were scientifically disproven by random trial studies.
Whitney gives the following example to illustrate: Before 1990, medical experts theorized that premature ventricular contractions, if left untreated, could increase one’s risk for sudden cardiac death, which accounted for thousands of fatalities per year in the United States. To address this concern, many practitioners supported the use of a particular drug therapy that was shown to be effective in suppressing the contractions.
It seemed to be a reasonable approachso much so that some experts argued it would be unethical to conduct a random trial to test the theory, since such a study would assign some patients to receive placebos rather than the drug therapy. Despite these protests, a randomized trial was conducted in 1990and it found that, far from helping reduce the risk of sudden cardiac death, the drug therapy actually increased it. The research made national newsand became a watershed event in gaining acceptance for evidence-based medicine.
