Study: Online Dashboard Improves Safety of Anticoagulant Prescribing

A research study suggests that use of an online dashboard can help doctors and pharmacists treating people with blood thinners reduce the rate of inappropriate dosing — as well as blood clots and strokes that can result from it.

The online dashboard, developed by the U.S. Veterans Health Administration in 2016, was designed to highlight and optimize the treatment of patients with direct oral anticoagulants, or DOACs, the most commonly prescribed blood thinners. 

Researchers led by Michigan Medicine used the tool to assess more than 120,000 cases in which patients with atrial fibrillation or venous thromboembolism, blood clots in the veins, were treated with DOACs at 123 VA hospitals from mid-2015 through 2019. 

They found that between 6.9 and 8.6% of patients received incorrect prescriptions for blood thinners. 

Adoption of the electronic DOAC patient management tool led to a decline in off-label dosing of around 8%. The rate of blood clots and stroke also declined at every hospital that implemented the monitoring tool.

Results are published in the Journal of the American Heart Association. 

“While DOACs are lifesaving medications for patients with common thrombotic conditions, they can also cause serious harm when prescribed inappropriately,” said Geoffrey Barnes, M.D., M.Sc., first author and associate professor of cardiology-internal medicine at U-M Medical School, in a statement. “Not only does our study show how commonly off-label dosing of DOACs occurs, but it highlights that utilizing this DOAC population health management tool can reduce that rate of inappropriate dosing as well as downstream complications, such as stroke and clotting.”

Direct oral anticoagulants can be incorrectly prescribed up to 20% of the time. 

The two most prescribed DOACs are rivaroxaban (brand name Xarelto) and apixaban (brand name Eliquis.)

The sites that used the system the longest demonstrated a more significant decline in inappropriate prescribing. 

In Michigan, the Michigan Anticoagulation Quality Improvement Initiative, a multi-center collaborative of statewide hospitals, built a similar dashboard using the Epic EHR. 

Five hospitals across the state currently use that system, including University of Michigan Health. Data on patients receiving anticoagulant therapy management from participating outpatient clinics are entered into a clinical registry at the MAQI2 Coordinating Center, which is located within the Michigan Cardiovascular Outcomes Research and Reporting Program (MCORRP) at the University of Michigan.

Several quality metrics are used to compare performance between sites. Participating sites meet on a quarterly basis to review quality metrics, share Best Practices, and learn about the most recent anticoagulation management guidelines and research. Quality improvement initiatives are conducted to improve patient outcomes and reduce healthcare costs.

“This study provides one of the largest and most impactful evaluations of an anticoagulation stewardship effort to show reduction in adverse clinical events,” Barnes added. “Health systems and policymakers should consider investing in anticoagulation stewardship efforts that support pharmacists in reviewing and correcting off label direct oral anticoagulant dosing for the benefit of millions of patients who take these medications.”
