Improving the Safe Use of Direct Oral Anticoagulants for Veterans
June 30, 2021
Takeaway: The Direct Oral Anticoagulants (DOAC) Dashboard is a population health management tool that facilities may use to evaluate their clinical practice and anticoagulation programs. It has been implemented at 127 (87%) VA healthcare sites and is in the process of being implemented at the remaining 19 (13%) VA sites. Altogether, more than 1,700 VA staff have been trained and/or currently use it. The DOAC Dashboard has served 212,150 Veterans.
Relatively new medications, direct oral anticoagulants (DOACs) include dabigatran (Pradaxa), rivaroxaban (Xarelto), apixaban (Eliquis), edoxaban (Savaysa), and betrixaban (Bevyxxa).
Use of direct oral anticoagulants (DOAC) is rapidly growing for the prevention and treatment of several cardiovascular conditions (i.e., atrial fibrillation and venous thromboembolism). With the increased use of DOACs, clinicians must make complex decisions regarding which DOAC to use, the duration of treatment, dosing, and use in special populations. For example, dosing recommendations differ for the DOACs based on indication, patient’s concurrent conditions, and metabolic function, which leads to incorrect dosing of these medications and puts patients at risk of adverse drug events. When DOACs are used inappropriately (over-dosing, under-dosing, and dosing based on the wrong indication), patients are at an increased risk for bleeding and thrombotic/stroke complications. One way to improve safe prescribing is the use of population health tools, including interactive dashboards built into the electronic health record (EHR) [Barnes et al., 2020].
In addition to the DOAC dashboard, four other national VA dashboards are currently in development:
1) Proton Pump Inhibitor Dashboard,
2) Anti-CD20 Antibody Dashboard,
3) Direct-Acting Antivirals-Hepatitis B Monitoring/Reactivation Dashboard, and
4) the GI-Azathioprine/6-Mercaptopurine Dashboard.
The Medication Safety (MedSafe) QUERI Program's national evaluation of the VA Office of Pharmacy Benefits Management’s (PBM) Medication Use Evaluation Tracker web application confirmed an interest in PBM/VA Center for Medication Safety (VA MedSAFE) for the development of national medication safety and appropriate medication use dashboards – to help identify and reduce potentially unsafe medication utilization.
In September 2017, in conjunction with PBM, Paul Heidenreich, MD, part of HSR&D’s Center for Innovation to Implementation (Ci2i) and principal investigator for the MedSafe QUERI Program, and HSR&D/QUERI investigator, Anju Sahay, PhD, invited subject matter experts, VISN Pharmacy Executives, and other key stakeholders to join VA PBM and VAMedSAFE leaders to form the VA PBM National Medication Safety Dashboard Committee. VAMedSAFE is led by Francesca Cunningham, PharmD, who, along with Dr. Paul Heidenreich and Dr. Sahay serve on the VA PBM National Medication Safety Dashboard Committee. This Committee meets quarterly and prioritized the development of five national dashboards as population health management tools. These dashboards are being designed to identify at-risk Veterans across all VA sites with regular data updates and daily accessibility to VA clinicians.
DOACs and COVID-19: The coronavirus disease may expose patients to increased risk for thrombosis, with prevalence rates from early reports ranging from 3-35% (Schutgens, 2021). See COVID-19 Treatment guidelines for “Antithrombotic Therapy in Patients with COVID-19” (NIH, 2021)
The Direct Oral Anticoagulant (DOAC) Dashboard is a patient management tool originally developed as a facility/VISN initiative. It was evaluated as a candidate for national use based on the occurrence of adverse events and the risk of therapeutic failures related to DOAC therapy. VAMedSAFE validated and optimized the report with the developer, and, in conjunction with the MedSafe QUERI Program, the DOAC Dashboard became the first national medication safety dashboard. In July 2019 it was made available at all 146 VA sites. The potential risks associated with DOAC use are evaluated and set as patient flags on the dashboard. Some of these flags include dosing issues, notable labs, medication interactions, and indications for use.
In implementing the DOAC Dashboard, HSR&D/QUERI investigators determined that the implementation strategies used most often by pharmacists included patient mailings, provider education, electronic reminders, and emailing draft orders. Strategies used least often by pharmacists included calling patients, academic detailing, and patient-specific care plans.
