Abstract
BACKGROUND The Management of Myocardial Injury after Non-Cardiac Surgery (MANAGE) trial demonstrated that dabigatran 110 mg twice daily was more effective than placebo in preventing the primary composite outcome of vascular mortality, non-fatal myocardial infarction, non-hemorrhagic stroke, peripheral arterial thrombosis, amputation and symptomatic venous thromboembolism in patients with myocardial injury after non-cardiac surgery (MINS). The cost implications of dabigatran for this population are unknown but are important given the significant clinical implications. METHODS Hospitalized events, procedures, and study and non-study medications were documented. We applied Canadian unit costs to healthcare resources consumed for all patients in the trial, and calculated the average cost per patient in Canadian dollars for the duration of the study (median follow-up of 16 months). A sensitivity analysis was performed using only Canadian patients, and subgroup analyses were also conducted. RESULTS The total study cost for the dabigatran group was $9985 per patient, compared with $10,082 for placebo, a difference of - $97 (95% confidence interval [CI] - $2128 to $3672). Savings arising from fewer clinical events and procedures in the dabigatran 110 mg twice-daily group were enough to offset the cost of the study drug. In Canadian patients, the difference was $250 (95% CI -$2848 to $4840). Both differences were considered cost neutral. Dabigatran 110 mg twice daily was cost saving or cost neutral in many subgroups that were considered. CONCLUSION Dabigatran 110 mg twice daily was cost neutral for patients in the MANAGE trial. Our cost findings support the use of dabigatran 110 mg twice daily in patients with MINS. TRIAL REGISTRATION ClinicalTrials.gov identifier number NCT01661101.

Demonstration of proof-of-concept of StrokeShield system for complete closure and occlusion of the left atrial appendage for non-valvular atrial fibrillation therapy. PLoS One 2021; 16:e0253299. [PMID: 34157041 PMCID: PMC8219146 DOI: 10.1371/journal.pone.0253299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2021] [Accepted: 06/01/2021] [Indexed: 11/29/2022] Open
Abstract
In the US, the most significant morbidity and mortality associated with non-valvular atrial fibrillation (NVAF) is embolic stroke, with 90% of thrombus originating from the left atrial appendage (LAA). Anticoagulation is the preferred treatment for the prevention of stroke in NVAF patients, but clinical studies have demonstrated high levels of non-compliance and increased risk of bleeding or ineligibility for anticoagulation therapy, especially in the elderly population where the incidence of NVAF is highest. Alternatively, stroke may be preventing using clinically approved surgical and catheter-based devices to exclude or occlude the LAA, but these devices continue to be plagued by peri-device leaks and thrombus formation because of residual volume. To overcome these limitations, Cor Habere (Louisville, KY) and the University of Louisville are developing a LAA closure device (StrokeShield) that completely occludes and collapses the LAA to minimize the risk of stroke. The StrokeShield device is a collapsible occluder (nitinol reinforced membrane) that completely covers the LAA orifice with an expandable conical coil anchor that attaches to the myocardium. The device is designed for catheter-based delivery and expands to completely occlude the LAA orifice and collapse the LAA. The primary advantages of the StrokeShield system are a completely sealed LAA (no peri-device flow or residual space) and smooth endothelialized connection to the left atrial wall with minimal risk of cardiac bleeding and tamponade. We tested proof-of-concept of a prototype StrokeShield device in acute (n = 2) and chronic 60-day (n = 2) healthy canine models. Acute results demonstrated that the conical coil securely attached to the myocardium (5N pull-out force) and the Nitinol umbrella fully deployed and covered the LAA ostium. Results from the chronic implants demonstrated long-term feasibility of device placement with no procedural or device-related intra- or post-operative complications, secure placement and correct positioning of the device with no device migration. The device successfully occluded the LAA ostium and collapsed the LAA with no interference with the mitral valve, circumflex coronary artery, or pulmonary veins. Necropsy demonstrated no gross signs of thrombus or end-organ damage and the device was encapsulated in the LAA. Histology demonstrated mature neointima covering the device with expected foreign body inflammatory response. These early positive results will help to guide the iterative design process for the continued development of the StrokeShield system.

Abstract
BACKGROUND Anticoagulant therapy is used for stroke prevention and proved to be effective and safe in the long term. The study aims to analyse the cost-effectiveness relationship of using of direct-acting oral anticoagulants vs vitamin K antagonists to prevent ischaemic stroke in patients with nonvalvular atrial fibrillation, including all the active ingredients marketed in Spain, prescribed for 2 years in the Primary Care service of the Institut Català de la Salut. METHODS Population-based cohort study, in which the cost of the 2 treatment groups will be evaluated. Direct costs (pharmacy, primary care, emergency and hospitalization) and indirect costs (lost productivity) will be included from a social perspective. Effectiveness (assessed as the occurrence of a health event, the 1 of primary interest being stroke) will be determined, with a 2-year time horizon and a 3% discount rate. The average cost of the 2 groups of drugs will be compared using a regression model to determine the factors with the greatest influence on determining costs. We will carry out a univariate ('one-way') deterministic sensitivity analysis. DISCUSSION We hope to provide relevant information about direct and indirect costs of oral anticoagulants, which, together with aspects of effectiveness and safety, could help shape the consensual decision-making of evaluating bodies.

Healthcare Utilization and Expenditures in Working-Age Adults with Atrial Fibrillation: The Effect of Switching from Warfarin to Non-Vitamin K Oral Anticoagulants. Am J Cardiovasc Drugs 2018; 18:513-520.

Abstract
OBJECTIVE Our objective was to evaluate the association between switching from warfarin to non-vitamin K oral anticoagulants (NOACs) and potential drug-drug interactions (DDIs), healthcare utilization, and expenditures in working-age adults with atrial fibrillation (AF). METHODS We conducted a retrospective cohort study using data from 2010 to 2015 for patients who switched from warfarin to NOACs (switchers) and those who continued to receive warfarin (non-switchers). We identified medications known or suspected to have clinically significant interactions with NOACs or warfarin. We used multivariate logistic regression, negative binomial, and generalized linear models to evaluate the influence of switching to NOACs and of potential DDIs on inpatient visits, outpatient visits, number of outpatient visits, and non-drug medical expenditures. Inverse probability of treatment weighting was also applied in analyses. RESULTS A total of 4126 patients with AF were included in the study. Switching to NOACs was significantly and negatively related to the number of outpatient, inpatient, and emergency room (ER) visits and non-drug medical expenditures. When potential DDIs were included in the models, switching remained significantly associated only with reduced inpatient and outpatient visits. Notably, having at least one potential DDI was associated with an increased likelihood of ER visits and the number of outpatient visits; it was also significantly and positively associated with non-drug medical expenditures. CONCLUSIONS Relative to persistent warfarin use, switching to NOACs was associated with fewer inpatient, ER, and outpatient visits and lower non-drug costs. Potential DDIs were also strongly and positively associated with healthcare utilization and expenditures. Both are critical to consider in the management of AF in working-age adults.
