Following up on Evidence-based Medicine

Thomas C. Meyer, MD, Medical Editor, Wisconsin Medical Journal

These quotes are taken from the editorial accompanying a previous issue of the Wisconsin Medical Journal dealing with Evidence-based Medicine. They were, in turn, lifted from the articles in that 1999 issue, which was designed as a primer in the use of EBM. It seemed appropriate to the Editorial Board to have a “follow-up issue” devoted to the same topic, and we are grateful to Dr Feldstein and his colleagues for providing the substance of this issue.

Evidence-based practice is here to stay

David A. Feldstein, MD

The term “Evidence-Based Medicine” (EBM) has become ubiquitous throughout the medical community. There is just no way to avoid it. Some practitioners become nervous at the mere mention of the words and others may struggle with putting the concepts into practice. There have been dramatic changes in the practice of EBM since the Wisconsin Medical Journal first published an EBM issue 6 years ago. The goals of this issue are to clarify the EBM process, describe the advances that have taken place in the past six years, address some of the major issues health care professionals face in integrating evidence into their practices, and discuss areas for future research.

Commentaries

Communicating Evidence: The Final Frontier

Christine S. Seibert, MD; Laura J. Zakowski, MD

Evidence-based medicine (EBM) has been described as “the integration of the best research evidence with clinical expertise and patient values.”1 Since EBM came on the scene, there has been significant emphasis on the steps of EBM that include framing an evidence-based question, retrieving and appraising the evidence, and understanding the results. However, finding and evaluating research evidence is only part of the task. The real challenge may lie in the clinician’s ability to communicate research evidence to patients to help them make informed decisions.

Original Research

Evidence-Based Practice: What a Start and ‘Oh, the Possibilities’

David A. Feldstein, MD

Evidence-based medicine (EBM) was introduced in the early 1990s. In less than 15 years, it has dramatically changed the way that medicine is practiced and taught. Improvements in informatics and evidence resources have helped overcome some of the initial problems and allowed busy clinicians to use EBM in practice. Many barriers to using EBM still remain. Further work on translating evidence into patient care decisions and understanding patients’ preferences is required in order to realize the improvements that EBM’s early proponents envisioned.

Finding the Best Available Evidence: What’s New?

Christopher Hooper-Lane, MA; Ann M. Combs, MA; David Feldstein, MD

The voluminous growth of the health literature paired with time constraints of practitioners can make it difficult to implement evidence-based medicine (EBM). New and better resources that summarize and/or synthesize the literature are available to facilitate the integration of evidence into practice. Understanding how such resources work and how to use them is an important step in finding evidence for patient care. By using a clinical scenario concerning abdominal aortic aneurysm screening, this article describes 3 types of EBM resources from the “4S” model: systems, synopses, and syntheses. The common features of each resource type are discussed and comparisons of selected examples are provided.

Making Evidence-Based Practice a Reality

Beth Potter, MD; Eric Rotert, MD

Busy doctors need answers, and quickly. Ely and colleagues observed that primary care clinicians generate approximately 3 questions every 10 patient visits.1 Additionally, the body of medical literature is growing exponentially. To keep up with primary care literature, it would be necessary to review 7287 articles per month, which would take approximately 29 hours per day.2 In 1992, the Journal of the American Medical Association introduced a formula for applying evidence-based medicine (EBM) in User’s Guide to the Medical Literature. With this method, a physician develops a clinical question from a patient encounter, performs a literature search, selects relevant articles, and critically appraises them to find the answer. Although rigorous, this approach is too cumbersome to use during a busy clinical day. Instead of critically appraising primary literature, most physicians seek information that has been pre-appraised—critically analyzed and summarized by someone else.3 In the Ely study, physicians attempted to answer only 40% of the 1101 questions they generated, spent less than 2 minutes looking, and did formal literature searches for only 2 questions. Physicians need to have a method for finding answers at the point-of-care.

Clinician’s Guide to Systematic Reviews and Meta-Analyses

David A. Feldstein, MD

Systematic reviews answer clinical questions by finding and evaluating all available evidence. The systematic review is a powerful tool to help clinicians use evidence for patient care decisions. There are many sources for high-quality systematic reviews. Like all scientific studies there are potential biases, but systematic reviews have many benefits over narrative reviews. To ensure appropriate use of systematic reviews, clinicians must evaluate them in a logical, step-by-step manner. This article will review the benefits of systematic reviews, how to locate them, and how to evaluate their quality and results.

Using Clinical Practice Guidelines to Improve Patient Care

Tosha B. Wetterneck, MD; Mary H. Pak, MD

Clinical practice guidelines incorporate the best available evidence for the management of a disease or an aspect of disease treatment or prevention into a single document for health care providers. The quality of practice guidelines has improved by adopting standard approaches to the development of guidelines and reviewing their quality for use in patient care. Implementing guidelines into clinical practice can improve quality and efficiency of care and will likely benefit from a multidisciplinary, multifaceted approach.

Evidence-Based Medicine for Medical Students: Introducing EBM in a Primary Care Rotation

William E Cayley, Jr, MD, MDiv

Background and Objectives: Evidence-based medicine (EBM) seeks to improve patients’ lives by applying the best available evidence to decisions affecting health outcomes. Since medical students often do not appreciate the value of an evidence-based approach to medicine when they enter third-year clinical training, a curriculum was developed introducing third-year students to the practice of EBM during a primary care clinical rotation.

Methods: Twenty-seven students over 4 rotations participated in the series of 6 hour-long seminars, and 8 items from a 27-item questionnaire were used to measure the impact on students’ self reported understanding and use of EBM. Results: Responses to questionnaires given before and after completion of the curriculum documented improved self-reported understanding of EBM and improved self-reported comfort with critical appraisal.

Conclusions: A seminar series introducing EBM in a primary care rotation improved students’ familiarity with and receptivity to use of EBM.

Meningococcal Disease Incidence and Mortality in Wisconsin, 1993–2002

Mark J. Sotir, PhD, MPH; Susann Ahrabi-Fard, MS; Donita R. Croft, MD, MS; James Kazmierczak, DVM, MS; Timothy A. Monson, MS; Mark V. Wegner, MD, MPH; Jeffrey P. Davis, MD

Neisseria meningitidis is a major cause of sepsis and meningitis in children and young adults in the United States. To examine recent epidemiologic features of meningococcal disease in Wisconsin, we evaluated Wisconsin case surveillance data collected during 1993–2002. Surveillance data for cases with onsets during this time were analyzed; statistical trends were assessed. Mortality was examined with regard to age, sex, serogroup, college student status, and young adult status by unadjusted and adjusted analyses. During 1993-2002, 462 cases of meningococcal disease were reported in Wisconsin; 55% of case patients were aged <19 years. The annual incidence was 0.9 cases per 100,000 persons per year, and incidence was highest among children aged <2 years. Two seasonal peaks in cases were observed during January–April and September–October. The annual mortality rate during the 10-year interval was 0.09 deaths per 100,000 persons per year. Adjusted analysis indicated that serogroup C infection, young adult, and college student status (but not sex) were associated with mortality. Meningococcal disease remains uncommon and sporadic in Wisconsin. Incidence and mortality rates are highest among young children, but young adults who acquire the disease appear to be at an increased mortality risk.

Case Reports

Transcatheter Closure of Atrial Septal Defect (Secundum Type): The Role of Echocardiography in Evaluating Interatrial Defects

Tahir Tak, MD, PhD, FACC; Anand Khurana, MD; Sumeesh Dhawan, MD

Atrial septal defects are among the most common congenital heart defects seen in the adult population. The diagnosis is usually made in children and closure is attempted before they are school age. In other cases, where the diagnosis is missed until adulthood, atrial arrhythmias and congestive heart failure are commonly seen. We report the case of an atrial septal defect (secundum type), which was diagnosed in a 72-year-old woman with paroxysmal atrial fibrillation. She also had a history of hypertension and hyperlipidemia. Transthoracic and transesophageal findings were consistent with right-sided volume overload and an atrial septal defect of approximately 1 cm in size. This was corroborated by the findings on cardiac catheterization with a shunt ratio of 1.8. The pulmonary artery pressures were within normal limits. The patient was referred for closure of the atrial septal defect. Presently, the options for septal defect closure are direct suture repair, Dacron patch repair depending on the size of the defect, and percutaneous transcatheter closure. Transcatheter closure is also available in treating selected patients with patent foramen ovale.

The DEA issues new clarification regarding prescribing Schedule II controlled substances

Ruth Heitz, JD

Physicians who write multiple prescriptions for Schedule II controlled substances (such as Ritalin) with instructions to pharmacists to fill the prescriptions on different dates should discontinue that practice, as it might be deemed to violate federal law. The Drug Enforcement Agency (DEA), which previously appeared to endorse the practice, has recently published clarification that instead suggests that the practice violates federal law prohibiting refills of Schedule II controlled substances.

General Practice in Northern Wisconsin

Joseph P. Cox, MD, Spooner, Wis

About one-sixth of the State Medical Society of Wisconsin is composed of men who have to deal with the peculiar conditions existing in Northern Wisconsin. During a residence there the past twenty long and eventful years, I have come to the conclusion that a general practice must be conducted on lines somewhat different from the practice in other localities...
