Background:CMS Star Ratings help inform beneficiaries about the performance of health and drug plans. Medication adherence is currently weighted at nearly half of a Part D plan’s Star Ratings. Including the adherence to non-vitamin-K-antagonist oral anticoagulants (NOACs) as a measure in the Star Ratings program may increase a plan’s incentives to improve patient adherence.Objective:To assess the adherence to medication of patients who used the NOACs rivaroxaban, dabigatran, or apixaban in 2014 based on the Pharmacy Quality Alliance (PQA) adherence measure.Methods:Healthcare claims from the Humana database between July 2013 and December 2014 were analyzed. Adult patients with ≥2 dispensings of NOAC agents in 2014, at least 180 days apart, with >60 days of supply, and ≥180 days of continuous enrollment prior to the index NOAC were identified. The PQA measure was calculated as the percentage of patients who had a proportion of days covered (PDC) ≥0.8. Multivariate logistic regression analyses were a...

Adherence to non-vitamin-K-antagonist oral anticoagulant medications based on the Pharmacy Quality Alliance measure

Background:The Pharmacy Quality Alliance (PQA) recently endorsed adherence to non-warfarin anticoagulant agents as a new performance measure, but the Medicare Part D Star Ratings program has not yet adopted the measure. The current study aims to assess the real-world adherence to medication of patients who used non-vitamin-K-antagonist oral anticoagulants (NOACs) based on the PQA’s adherence measure.Methods:Healthcare claims from the Humana database during the year of 2013 were analyzed. Patients older than 18 with ≥2 dispensings of NOAC agents, at least 180 days apart between two NOAC dispensings in 2013 (a criterion to include chronic users), with ≥60 days of supply, and ≥180 days of continuous enrollment prior to the index NOAC were identified. The PQA measure on the index therapy was calculated as the percentage of patients who had a proportion of days covered (PDC) ≥0.8 during their follow-up.Results:A total of 9948 NOAC users (rivaroxaban: n = 4194, dabigatran: n = 5489, apixaban: n = 265) w...

Pharmacy quality alliance measure: adherence to non-warfarin oral anticoagulant medications

Comparison of Adherence to Rivaroxaban Versus Apixaban Among Patients With Atrial Fibrillation.

Introduction
New target-specific oral anticoagulants may have benefits, such as shorter hospital length of stay, compared to warfarin in patients with nonvalvular atrial fibrillation (NVAF). This study aimed to assess, among patients with NVAF, the effect of rivaroxaban versus warfarin on health care costs in a cohort of rivaroxaban users and matched warfarin users.

Effect of Rivaroxaban Versus Warfarin on Health Care Costs Among Nonvalvular Atrial Fibrillation Patients: Observations from Rivaroxaban Users and Matched Warfarin Users

The development of new orally administered anticoagulants, such as dabigatran, rivaroxaban, and apixaban, in the past few years has focused on avoiding some of the drawbacks associated with warfarin. This work aims to illustrate the main features of the most commonly used new oral anticoagulants, reviewing the current literature on the management of patients taking these drugs and needing oral and implant surgery, and discussing the currently proposed related guidelines.

Managing dentoalveolar surgical procedures in patients taking new oral anticoagulants

Well-documented drawbacks of traditional anticoagulants have lead to the quest for an ideal anticoagulant resulting in a surge of novel anticoagulant molecules. These newer agents directly target specific steps in coagulation cascade and include newer low molecular weight heparins (adomiparin), ultra low molecular weight heparins (semuloparin, RO-14), inhibitors of activated factor II (dabigatran, AZD0837), X (rivaroxaban, apixaban, edoxaban, betrixaban), IX (REG1,2), XI (antisense oligonucleotides, BMS 262084, clavatadine A), VII/tissue factor (tifacogin, PCI 274836, and BMS 593214), V (recomodulin, solulin), VIII (TB402), dual thrombin/factor X inhibitors (EP21709, tanogitran), and newer vitamin K antagonists (tecarfarin). Direct thrombin inhibitors and Factor X inhibitors are the most clinically advanced. This article discusses the recent advances in the development of novel targets of anticoagulants. Medline, EMBASE, cochrane database, medscape, SCOPUS, and clinicaltrials.gov were searched using terms "anticoagulants", "blood coagulation inhibitors", "anticoagulants and venous thromboembolism", "anticoagulants and atrial fibrillation", and "'antithrombins." Journal articles published from 2007 to 2012 discussing pharmacology and/or clinical trials were screened.
