Evidence Based Medicine (Journal)
The purpose of Evidence-Based Medicine is to alert clinicians to important advances in internal medicine, general and family practice, surgery, psychiatry, paediatrics, and obstetrics and gynaecology by selecting from the biomedical literature those original and review articles whose resulsts are most likely to be both true and useful. These articles are summzarised in value-added abstracts and commented on by clinical esperts. The author of the original is given an opportunity to review the abstract and commentary before publication.
The procedures we follow as we attempt to achieve this purpose are:
The BMJ Publishing Group publish Evidence-Based Medicine bimonthly, under the editorship of Professor R Brian Haynes at McMaster University and Professor Paul Glasziou at the University of Oxford.
Acta Obstet Gynecol Scand
Arch Pediatr Adolesc Med
|J Vas Surg
Med J Aust
N Engl J Med
|* Approximately 60 additional journals are reviewed. This list is available upon request at firstname.lastname@example.org|
All English-language original and review articles in an issue of a candidate journal are consdiered for abstracting if they concern topics improtant to the clinical practice of internal medicine, general and family practice, surgery, psychiatry, paediatrics, or obstetrics and gynaecology. Access to foreign-language journals is provided through the systematic reviews we abstract, especially those in the Cochrane Library, which summarises articles taken from over 800 journals in several languages.Prevention or treatment; quality improvement
An inception cohort of persons, all initially free of the outcome of interest
Follow-up of ³ 80% of patients until the occurrence of either a major study end point or the end of the study.
Observations concerning the relation between exposures and putative clinical outcome
Prospective data collection with clearly identified comparison group(s) for those at risk for the outcome of interest (in descending order of preference from randomised controlled trials, quasi-randomised controlled trials, nonrandomised controlled trials, cohort studies with case by case matching or statistical adjustment to create comparable groups, to nested case control studies)
Masking of observers of outcomes to exposures (this criterion is assumed to be met if the outcome is objective).
Economics of health care programmes or intervention
The economic question must compare alternative courses of action in real or hypothetical patients
The alternative diagnostic or therapeutic services or quality improvement strategies must be compared on the basis of both the outcomes they produce (effectiveness) and the resources they consume (costs)
Evidence of effectiveness must come from a study (or studies) that meets criteria for diagnosis, treatment, quality assurance, or review articles
Results should be presented in terms of the incremental or additional costs and outcomes incurred and a sensitivity analysis should be done.
Clinical prediction guides
The guide must be generated in 1 set of patients (training set) and validated in an independent set of real not hypothetical patients (test set), and must pertain to treatment, diagnosis, prognosis, or causation.
A cohort of patients who present with a similar, initially undiagnosed but reproducibly defined clinical problem
Clinical setting is explicitly described
Ascertainment of diagnosis for 80% of patients using a reproducible diagnostic workup strategy and follow up until patients are diagnosed or follow up of 1 month for acute disorders or ³1 year for chronic or relapsing disorders.
The clinical topic being reviewed must be clearly stated; there must be a description of how the evidence on this topic was tracked down, from what sources, and with what inclusion and exclusion criteria
³1 article included in the review must meet the above-noted criteria for treatment, diagnosis, prognosis, causation, quality improvement, or the economics of health care programmes.
Evidence-Based Medicine has a related journal, ACP Journal Club. It is generated using procedures identical to those used for Evidence-Based Medicine and is published by the American College of Physicians. Approximately one third of the abstracts in ACP Journal Club are published in Evidence-Based Medicine, and the abstracts not published are listed, by their declarative titles, in the section titled Additional Articles Abstracted in ACP Journal Club.
