BG, UKCorrespondence to T Greenhalgh p. Trisha Greenhalgh and colleagues argue that, although evidence based medicine has had many benefits, it has also had some negative unintended consequences. They offer a preliminary agenda for the movements renaissance, refocusing on providing useable evidence that can be combined with context and professional expertise so that individual patients get optimal treatment. It is more than 2. Tradition, anecdote, and theoretical reasoning from basic sciences would be replaced by evidence from high quality randomised controlled trials and observational studies, in combination with clinical expertise and the needs and wishes of patients. Evidence based medicine quickly became an energetic intellectual community committed to making clinical practice more scientific and empirically grounded and thereby achieving safer, more consistent, and more cost effective care. Achievements included establishing the Cochrane Collaboration to collate and summarise evidence from clinical trials 3 setting methodological and publication standards for primary and secondary research 4 building national and international infrastructures for developing and updating clinical practice guidelines 5 developing resources and courses for teaching critical appraisal 6 and building the knowledge base for implementation and knowledge translation. From the outset, critics were concerned that the emphasis on experimental evidence could devalue basic sciences and the tacit knowledge that accumulates with clinical experience they also questioned whether findings from average results in clinical studies could inform decisions about real patients, who seldom fit the textbook description of disease and differ from those included in research trials. But others argued that evidence based medicine, if practised knowledgably and compassionately, could accommodate basic scientific principles, the subtleties of clinical judgment, and the patients clinical and personal idiosyncrasies. Two decades of enthusiasm and funding have produced numerous successes for evidence based medicine. An early example was the British Thoracic Societys 1. Subsequently, the use of personal care plans and step wise prescription of inhaled steroids for asthma increased,1. More recently, uptake of the UK National Institute for Health and Care Excellence guidelines for prevention of venous thromboembolism after surgery has produced significant reductions in thromboembolic complications. Despite these and many other successes, wide variation in implementing evidence based practice remains a problem. For example, the incidence of arthroscopic washout of the knee joint, whose benefits are unproved except when there is a known loose body, varies from 3 to 4. England. 1. 3 More fundamentally, many who support evidence based medicine in principle have argued that the movement is now facing a serious crisis box 1. Below we set out the problems and suggest some solutions. Box 1 Crisis in evidence based medicine The evidence based quality mark has been misappropriated by vested interests. The volume of evidence, especially clinical guidelines, has become unmanageable. Statistically significant benefits may be marginal in clinical practice. Inflexible rules and technology driven prompts may produce care that is management driven rather than patient centred Evidence based guidelines often map poorly to complex multimorbidity. Distortion of the evidence based brand. The first problem is that the evidence based quality mark has been misappropriated and distorted by vested interests. In particular, the drug and medical devices industries increasingly set the research agenda. They define what counts as disease for example, female sexual arousal disorder, treatable with sildenafil. They also decide which tests and treatments will be compared in empirical studies and choose often surrogate outcome measures for establishing efficacy. Furthermore, by overpowering trials to ensure that small differences will be statistically significant, setting inclusion criteria to select those most likely to respond to treatment, manipulating the dose of both intervention and control drugs, using surrogate endpoints, and selectively publishing positive studies, industry may manage to publish its outputs as unbiased studies in leading peer reviewed journals. Use of these kinds of tactic in studies of psychiatric drugs sponsored by their respective manufacturers enabled them to show that drug A outperformed drug B, which outperformed drug C, which in turn outperformed drug A. One review of industry sponsored trials of antidepressants showed that 3. Evidence based medicines quality checklists and risk of bias tools may be unable to detect the increasingly subtle biases in industry sponsored studies. Some so called evidence based policies such as dementia case finding for the over 7. UK seem to be based largely on political conviction. Critics have condemned the role of the drug industry in influencing the policy makers who introduced them. Too much evidence. The second aspect of evidence based medicines crisis and yet, ironically, also a measure of its success is the sheer volume of evidence available. In particular, the number of clinical guidelines is now both unmanageable and unfathomable. One 2. 00. 5 audit of a 2. Marginal gains and a shift from disease to risk. Evidence based medicine is, increasingly, a science of marginal gainssince the low hanging fruit interventions that promise big improvements for many conditions were picked long ago. After the early big gains of highly active antiretroviral therapy for HIV2. Helicobacter pylori positive peptic ulcer,2. Large trials designed to achieve marginal gains in a near saturated therapeutic field typically overestimate potential benefits because trial samples are unrepresentative and, if the trial is overpowered, effects may be statistically but not clinically significant and underestimate harms because adverse events tend to be underdetected or underreported. The 7. 4 year old who is put on a high dose statin because the clinician applies a fragment of a guideline uncritically and who, as a result, develops muscle pains that interfere with her hobbies and ability to exercise, is a good example of the evidence based tail wagging the clinical dog. In such scenarios, the focus of clinical care shifts insidiously from the patient this 7. As the examples above show, evidence based medicine has drifted in recent years from investigating and managing established disease to detecting and intervening in non diseases. Risk assessment using evidence based scores and algorithms for heart disease, diabetes, cancer, and osteoporosis, for example now occurs on an industrial scale, with scant attention to the opportunity costs or unintended human and financial consequences.
