Management of Outpatient Warfarin Therapy amid COVID-19 Pandemic: A Practical Guide

Area of Science:

• Pharmacology
• Internal Medicine
• Public Health

Background:

• COVID-19 pandemic has significantly impacted healthcare resource allocation.
• Management of patients on warfarin therapy may be compromised due to pandemic-related disruptions.
• Maintaining effective anticoagulation is crucial for preventing thrombotic events.

Purpose of the Study:

• To provide a stepwise algorithm for managing outpatient warfarin therapy during the COVID-19 pandemic.
• To discuss alternative management strategies, including pharmacological options and self-monitoring.
• To assist clinicians in optimizing anticoagulation treatment for patients amidst the global health crisis.

Main Methods:

• Review and synthesis of current literature on warfarin management and COVID-19 impact.
• Development of a structured, stepwise clinical algorithm.
• Discussion of evidence supporting alternative anticoagulation therapies and self-monitoring approaches.

Main Results:

• A clear, actionable algorithm for outpatient warfarin management is proposed.
• Alternative pharmacological agents and self-monitoring techniques are evaluated for safety and efficacy.
• Strategies aim to mitigate risks associated with disrupted warfarin care.

Conclusions:

• The proposed algorithm offers a framework for safe and effective outpatient warfarin management during the pandemic.
• Alternative strategies like novel oral anticoagulants and patient self-testing can support continued anticoagulation.
• Proactive management is essential to prevent adverse events and ensure patient safety in anticoagulation therapy.
