OBJECTIVE: To review the clinical trials evaluating warfarin for primary stroke prophylaxis in nonvalvular atrial fibrillation (NVAF), to discuss the relative benefits and risks of warfarin versus aspirin therapy, and to review the clinical practice guidelines and identify potential barriers to their implementation in clinical practice. DATA SOURCES: A MEDLINE literature search was performed to identify clinical trials of antithrombotic therapy for NVAF, clinical practice guidelines, studies evaluating physician practices and attitudes, cost-effectiveness studies, and pertinent review articles. Key search terms included atrial fibrillation, stroke, antithrombotic, warfarin, aspirin, and cost-effectiveness. DATA EXTRACTION: Prospective, randomized clinical trials were selected for analysis. Clinical practice guidelines from recognized panels of experts were reviewed. Comprehensive review articles were selected. DATA SYNTHESIS: NVAF is a common arrhythmia that is associated with a substantial risk for stroke. Seven prospective, randomized, clinical trials have conclusively demonstrated the efficacy of warfarin for stroke prevention. The greatest benefits are achieved in older patients and those with comorbidities that increase their risk for stroke. The potential benefits of preventing a devastating stroke, however, must be weighed against the potential for bleeding complications. Warfarin has been shown to be cost-effective in high-risk patients, provided the rate of complications is minimized. Nonetheless, many physicians remain hesitant to implement warfarin therapy in older, high-risk patients. The clinical data on aspirin are less consistent than those observed with warfarin. Aspirin appears to be most effective in younger individuals or those considered to be at low risk for stroke. CONCLUSIONS: In patients with NVAF, the personal, social, and economic consequences of stroke are often devastating. Clinical trials have provided definitive proof that the risks of stroke can be significantly reduced through the use of appropriate antithrombotic therapy. Despite this evidence and the recommendations of a number of clinical practice guidelines, variations in care exist that continue to place patients at risk. Additional outcomes research is needed to evaluate the impact of the clinical trial findings and practice guidelines on clinical practice and to develop methods for overcoming barriers to implementation.

Abstract Venous thromboembolism (VTE) is a major therapeutic concern in cancer patients and the leading cause of death after metastasis. Providing anticoagulant therapy to this patient population is challenging because cancer patients are at increased risk of VTE recurrence and bleeding, and treatment management is often complicated by other co-morbidities that affect choice of anticoagulation. The International Initiative on Thrombosis and Cancer (ITAC-CME) is a multidisciplinary group of International academic clinicians, researchers, and experts dedicated to reducing the global burden of VTE and its consequences in cancer patients. In 2013, the group published international clinical practice guidelines for the treatment and prophylaxis of VTE in cancer (1, 2). In collaboration with CME solutions, an accredited CME provider, ITAC-CME developed a mobile web-based application to promote the international implementation of the 2013 guidelines, in English and French (www.itacc-cme.org). Usage of the app has steadily increased every year since its release. ITAC-CME recently revised its consensus recommendations according to a systematic review of the literature up to January 2016. In particular, the ISTH-endorsed updated recommendations provide a guidance on the use of the direct oral anticoagulants based on the current level of evidence (3). ITAC-CME and CME solutions have updated the web-based application to support the 2016 guidelines. The app also includes several new features, including interactive case-based CME learning activities, with pre- and post-activity practice assessments. These pre- and post-test metrics will be documented to record international clinical practice patterns, and monitor the impact of the app on the adoption of the 2016 guidelines into clinical practice worldwide. Translation of the 2016 updated app into additional languages is planned. The application has been submitted for accreditation with the royal College of Physicians and surgeons of Canada, the American Medical Association, the European Union of Medical Specialists, l' Organisme Gestionnaire du Développement Professionnel Continu, and the European Board for Accreditation in Hematology. 1 Debourdeau P, Farge D, Beckers M, Baglin C, Bauersachs RM, Brenner B, Brilhante D, Falanga A, Gerotzafias GT, Haim N, Kakkar AK, Khorana AA, Lecumberri R, Mandala M, Marty M, Monreal M, Mousa SA, Noble S, Pabinger I, Prandoni P, Prins MH, Qari MH, Streiff MB, Syrigos K, Büller HR, Bounameaux H.

This chapter assesses theory and evidence on the efficacy of medical malpractice liability and limitations to it in improving healthcare outcomes, and identifies unresolved issues that merit further attention from scholars. First, it explores the theoretical and legal background on medical malpractice. It then turns to the available evidence by focusing on three basic areas of study: the impact of malpractice limitations on payouts and litigation, the effect of malpractice limitations on overall healthcare costs, and the effect of malpractice on two major cost drivers in the healthcare system: cardiac and obstetrics practice. It argues that limitations on liability did not and likely cannot significantly reduce healthcare costs. Finally, the chapter discusses new and important trends in the literature regarding reforms to standards of care and the role of clinical practice guidelines and communication and disclosure programs.

Clinical trials have attracted negative attention recently. The degree of control of the pharmaceutical industry over the design, conduct and analysis of clinical trials has been criticized. Healthcare professionals increasingly rely on data obtained from clinical trials and from meta-analysis and systematic reviews. The process of publishing clinical trials and framing clinical practice guidelines is being increasingly influenced by the pharmaceutical industry.

The incidence of leukemia, along with its precursor, myelodysplasia, appears to be rising, particularly in the population over age 60. Recently an expanded panel of clinicians from the NCCN member institutions joined to update guidelines for the treatment of acute myeloid leukemia. Although there are some areas in which clinical trials have led to significant improvements in treatment, for the most part, recent trials have only served to highlight the continued need for innovative strategies to overcome this disease. These guidelines focus on outlining reasonable treatment options based on the information available. For the most recent version of the guidelines, please visit NCCN.org
