Association of Oral Anticoagulants and Proton Pump Inhibitor Cotherapy With Hospitalization for Upper Gastrointestinal Tract Bleeding. Importance: Anticoagulant choice and proton pump inhibitor (PPI) cotherapy could affect the risk of upper gastrointestinal tract bleeding, a frequent and potentially serious complication of oral anticoagulant treatment. Objectives: To compare the incidence of hospitalization for upper gastrointestinal tract bleeding in patients using individual anticoagulants (...) with and without PPI cotherapy, and to determine variation according to underlying gastrointestinal bleeding risk. Design, Setting, and Participants: Retrospective cohort study in Medicare beneficiaries between January 1, 2011, and September 30, 2015. Exposures: Apixaban, dabigatran, rivaroxaban, or warfarin with or without PPI cotherapy. Main Outcomes and Measures: Hospitalizations for upper gastrointestinal tract bleeding: adjusted incidence and risk difference (RD) per 10 000 person-years of anticoagulant

These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients, clinicians and other health care professionals in their decisions about the use of anticoagulants in the management of VTE. These guidelines assume the choice of anticoagulant has already been made. ASH formed a multidisciplinary guideline panel balanced to minimize potential bias from conflicts of interest. The McMaster University GRADE Centre supported the guideline
Impact of anticoagulant choice on hospitalized bleeding risk when treating cancer-associated venous thromboembolism 30240508 2018 10 25 1538-7836 2018 Sep 21 Journal of thrombosis and haemostasis : JTH J. Thromb. Haemost. Impact of anticoagulant choice on hospitalized bleeding risk when treating cancer-associated venous thromboembolism. 10.1111/jth.14303 Essentials Bleeding risk by anticoagulant choice for cancer-associated venous thrombosis (CA-VTE) is unknown. 26 894 people with CA-VTE were (...) followed for bleeding in a claims database in the United States. Hospitalized bleeding risk was similar with direct acting oral anticoagulants vs. warfarin. Relative hospitalized bleeding risk varied by cancer type and anticoagulant choice. SUMMARY: Background Direct acting oral anticoagulants (DOACs) are associated with less bleeding than traditional venous thromboembolism (VTE) treatments in the general population but are little studied in cancer-associated VTE (CA-VTE). Objective To determine

Screen reminders for GPs did not improve anticoagulant prescribing in atrial fibrillation Signal - Screen reminders for GPs did not improve anticoagulant prescribing in atrial fibrillation Dissemination Centre Discover Portal NIHR DC Discover Screen reminders for GPs did not improve anticoagulant prescribing in atrial fibrillation Published on 18 July 2017 General practice software that generated screen reminders for patients with atrial fibrillation did not increase the proportion taking oral (...) anticoagulants appropriately by six months. This NIHR-funded trial included GPs in 47 surgeries in England and found that at the start only 63% of eligible patients with atrial fibrillation were being prescribed anticoagulants. Six months later the rate had increased to 66% in intervention practices and 64% in those following usual practice, a non-significant difference between the groups. Use of the software was associated with increased diagnosis of transient ischemic attack, which could be due to improved
New generation anticoagulants may be safer than warfarin for people with chronic kidney disease Signal - New generation anticoagulants may be safer than warfarin for people with chronic kidney disease Dissemination Centre Discover Portal NIHR DC Discover New generation anticoagulants may be safer than warfarin for people with chronic kidney disease Published on 26 April 2016 Newer generation anticoagulants appear to reduce the risk of bleeding compared with older anticoagulants like warfarin (...) , when used to prevent clots in people who also have mild to moderate chronic kidney disease. This group of drugs, called direct oral anticoagulants, have been well researched in healthy people with atrial fibrillation or at risk of thromboembolism but this was the first review to look at their safety, in terms of bleeding and risk of bleeding within the brain, in people with kidney disease. As a group, these newer drugs appear safer than older anticoagulants such as warfarin. Evidence from
Extending anticoagulant treatment beyond three months reduces the risk of recurrent blood clots Signal - Extending anticoagulant treatment beyond three months reduces the risk of recurrent blood clots Dissemination Centre Discover Portal NIHR DC Discover Extending anticoagulant treatment beyond three months reduces the risk of recurrent blood clots Published on 1 March 2016 Warfarin, newer direct oral anticoagulants and aspirin all significantly reduced the rate of recurrent clots in patients (...) treated for more than the standard three months. Aspirin was the least effective and the number of major bleeds and deaths was low in all three groups. This review pooling seven trials found that between six and 36 months 28 in every 1000 people taking warfarin, direct oral anticoagulants or aspirin after a first blood clot developed a second clot. This was significantly fewer than the 97 per 1000 people who developed a second clot while taking placebo. The cost-effectiveness of extending treatment
An anticoagulant, bivalirudin, may not be safer than the alternative, heparin, when unblocking arteries in the heart Signal - An anticoagulant, bivalirudin, may not be safer than the alternative, heparin, when unblocking arteries in the heart Dissemination Centre Discover Portal NIHR DC Discover An anticoagulant, bivalirudin, may not be safer than the alternative, heparin, when unblocking arteries in the heart Published on 14 June 2016 Bivalirudin is currently recommended as an alternative (...) arteries. In 2013, over 92,000 procedures were carried out in the UK. It involves inserting a small tube called a stent into the heart’s arteries, to hold them open. Anticoagulant treatment is needed at the same time to reduce the risk of clotting during and after the procedure. Heparin is the long established anticoagulant, but newer bivalirudin may now be used as an alternative. To date, different trials have produced contradictory evidence comparing the safety and effectiveness of the two
