Based on clinical and health-economic evidence from the PLATO study, treating ACS patients with ticagrelor for 12 months is associated with a cost per QALY below generally accepted thresholds for cost-effectiveness. ClinicalTrials.gov Identifier: NCT00391872.

To evaluate the thromboprophylactic use of low molecular weight heparins (LMWHs), publications from 27 orthopaedic trials and 35 studies of patients undergoing general or gynaecological surgery were scrutinized and subjected to a partial meta-analysis. In orthopaedic surgery, LMWHs were superior to placebo or dextran and at least as efficient as unfractionated heparin in the prevention of deep vein thrombosis (DVT). Compared with unfractionated heparin, one of the LMWH preparations significantly reduced the total incidence of DVT. The rate of non-fatal pulmonary embolism was 0.49 per cent in patients receiving LMWH and 1.22 per cent in controls. Seven orthopaedic patients (0.15 per cent) died from pulmonary embolism, none of whom received LMWH. In general surgery, the LMWHs were at least as efficient as unfractionated heparin, with a trend towards a lower risk of pulmonary embolism with the former. Compared with unfractionated heparin, LMWHs did not reduce the postoperative mortality rate, nor did they cause haemorrhage. LMWHs provide safe and efficient prophylaxis by administration once daily.

We conducted a retrospective cohort study of thromboprophylaxis rates and the quality of anticoagulation control among patients with atrial fibrillation (AF) using a large, geographically diverse database of electronic medical records. The study population consisted of 13,709 AF patients treated in US outpatient physician practices. Approximately two-thirds were prescribed warfarin alone or in combination with another drug. Older patients, males, and those with congestive heart failure (CHF) or prior stroke were more likely to receive antithrombotic therapy. Among 6454 patients treated with warfarin who had at least two valid prothrombin time/international normalised ratio test results, approximately half of study days were spent in target range. Female sex, CHF and residence in the Northeast were associated with more time out of range. Our study confirms that, in routine medical practice, warfarin is not prescribed for substantial numbers of eligible patients, and anticoagulation control with warfarin is suboptimal for many of those at risk for thromboembolism.

Background: Anticoagulation can reduce quality of life, and different models of anticoagulation management might have different impacts on satisfaction with this component of medical care. Yet, to our knowledge, there are no scales measuring quality of life and satisfaction with anticoagulation that can be generalized across different models of anticoagulation management. We describe the development and preliminary validation of such an instrument -the Duke Anticoagulation Satisfaction Scale (DASS).
