Insights

Electronic health record alerts for atrial fibrillation (AF) anticoagulation management improved provider engagement. Real-time risk score integration supported clinical decisions, particularly for initiating anticoagulation in high-risk patients.

Area of Science:

  • Internal Medicine
  • Cardiology
  • Health Informatics

Background:

  • Anticoagulation decisions in atrial fibrillation (AF) require balancing stroke and bleeding risks using CHA₂DS₂-VASc and HAS-BLED scores.
  • Manual calculation of these risk scores is time-consuming and prone to inconsistency.
  • Electronic Health Record (EHR) integration offers a potential solution for streamlining risk assessment.

Purpose of the Study:

  • To evaluate the impact of real-time, EHR-integrated alerts on provider behavior in anticoagulation management for AF patients.
  • To assess physician and non-physician provider (NPP) interaction with an EHR-based advisory tool.

Main Methods:

  • A single-arm observational study was conducted at a rural academic primary care clinic.
  • An EHR rules-based engine calculated CHA₂DS₂-VASc and HAS-BLED scores and displayed them via non-interruptive alerts.
  • Provider interactions (initiation of anticoagulation, documented rationale, exclusion diagnosis) were analyzed using chi-square testing.

Main Results:

  • Among 313 patients triggering alerts, 16.9% were newly anticoagulated, and 35.8% had a documented rationale for not initiating therapy.
  • 50.5% of patients experienced a clinically meaningful interaction with the alert tool (χ² = 9.82, p = 0.0017).
  • The overall alert success rate across 2,447 encounters was 19.8%, indicating significant point-of-care engagement.

Conclusions:

  • Real-time EHR alerts displaying stroke and bleeding risk scores are associated with meaningful provider engagement in AF anticoagulation management.
  • The tool demonstrated potential in supporting point-of-care decision-making, particularly for initiating anticoagulation in high-risk individuals.
  • Further investigation of EHR-based advisories is warranted to enhance anticoagulation management in AF.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
