December 16, 2021


December 7, 2022


Health-system pharmacists and other pharmacists who may manage patients with undiagnosed Non-Valvular Atrial Fibrillation (NVAF).


During the period December 16, 2021 to December 7, 2022, participants must 1) read the learning objectives and faculty disclosures; 2) view the educational activity; and 3) complete the posttest and evaluation form directly after the activity within a maximum of 60 days of participating in the activity. To answer the questions, click on your selected choice for each answer then proceed to the next question. Once completed, click on the Grade Exam button at the bottom of the page. Your posttest will automatically be graded. If you successfully complete the posttest (score of 70% or higher), your statement of participation will be made available immediately. Click on the View Statement of Participation link and print the statement for your records. If you receive a score lower than 70%, you will receive a message notifying you that you did not pass the posttest. You will have 2 opportunities to pass the posttest. To receive Credit, you must provide your date of birth and NABP number. All Credit information will be uploaded into CPE monitor within 30 days.


To educate health-system pharmacists on the burden and consequences of undiagnosed and untreated Non-Valvular Atrial Fibrillation (NVAF), improve the identification of undiagnosed NVAF, and effectively manage patients with NVAF in order to reduce the risk of preventable stroke.


Upon completion of this program, participants should be better able to:

  • Explain the implications of undiagnosed/untreated NVAF and discuss the various types of screening methods for AF
  • Discuss principles of stroke prevention in newly diagnosed NVAF
  • Compare pharmacological characteristics, efficacy, and safety profiles of oral anticoagulants used for stroke prevention in NVAF
  • Formulate individualized, evidence-based anticoagulation plans for newly diagnosed/previously untreated patients with NVAF using a shared decision-making process

Slide Clarification
Slide 11: Screening for AF The April 2021 US Preventive Services Task Force (USPSTF) recommendations for Screening for Atrial Fibrillation are Draft Recommendations, that as of January 3, 2022, have not been approved.

Note: These recommendations are consistent with the most recently approved 2018 USPSTF recommendations.1

Slide 13: Screening for AF Mechanism for Patch:
Electrocardiogram (ECG) patch can be worn from 7-14 days, providing the patient some flexibility.
Slide 22: Balancing Risks and Benefits Clarification: “High-dose” vs “Low-dose” new oral anticoagulants (NOACs)
“High-dose” or “standard clinical study dose" NOACs
• Apixaban 5 mg BID
• Dabigatran 150 mg BID
• Edoxaban 60 mg once daily
• Rivaroxaban 20 mg once daily

"Low-dose" or "reduced clinical study dose" NOACs
• Apixaban 2.5 mg BID
• Dabigatran 110 mg BID
• Edoxaban 30 mg once daily
• Rivaroxaban 15 mg once daily
Slides 64 & 65: Periprocedural Management Additional Information:
While slides 64 and 65 focus on the management of warfarin interruption for procedures, it is helpful to acknowledge the different approaches needed with NOACs. The Perioperative Anticoagulation Use for Surgery Evaluation (PAUSE) study demonstrated that NOAC interruption duration should be adjusted based on the procedure’s bleeding risk (high- vs low-risk) and the patient’s renal function (for dabigatran specifically) to maintain safety.1 Most NOAC medications can be omitted for 24 hours in low bleeding risk procedures, while holding 48 hours is recommended for higher bleed risk procedures, and dabigatran requires longer interruptions in lower renal function patients (up to 4 days).1

High bleeding risk procedures tend to be more invasive and include major surgery with extensive tissue injury; cancer surgery; major orthopedic surgery; reconstructive plastic surgery; surgery in high vascular organs (kidneys, liver, spleen); cardiac, intracranial, spinal, and most urologic or gastrointestinal (GI) surgeries; plus any procedure with duration >45 minutes.2 Low bleeding risk procedure examples include GI endoscopy, colonoscopy, laparoscopic cholecystectomy, hernia repair, hemorrhoidal surgery, bronchoscopy, shoulder/foot/hand surgeries, and cutaneous/lymph node biopsies.2  This timeline of NOAC interruption is corroborated by Merli et al’s findings that apixaban was almost fully cleared from patients’ bloodstream (≤30 ng/mL) 94% of the time with a 48-hour omission of dosing.3
