Patient values and preferences when choosing anticoagulants

Area of Science:

• Cardiology
• Pharmacology
• Health Services Research

Background:

• Newer oral anticoagulants offer similar efficacy and lower bleeding risk than warfarin.
• A key limitation of novel anticoagulants is the absence of a specific antidote for bleeding events.
• Patient preferences for anticoagulation therapy, especially regarding safety and convenience, are crucial.

Purpose of the Study:

• To evaluate patient preferences and values concerning anticoagulation choices for atrial fibrillation.
• To understand patient priorities when selecting between different anticoagulant profiles.
• To assess whether patients desire active involvement in their anticoagulation decision-making process.

Main Methods:

• A cross-sectional study involving Veterans at risk for atrial fibrillation was conducted.
• A survey instrument, developed with patient and physician input, assessed preferences using a hypothetical anticoagulant scenario.
• Participants indicated preferences based on efficacy, duration of market presence, antidote availability, quality of life, or physician recommendation.

Main Results:

• A high percentage of patients (98%) desired participation in anticoagulant selection.
• A significant proportion of both exposed (36%) and unexposed (37%) patients favored an antidote, even for minor bleeding risks.
• Quality of life and reduced laboratory monitoring were also important factors for 22-23% of participants.

Conclusions:

• Patients facing anticoagulation decisions strongly prefer active participation in the process.
• Individual patient values and preferences for anticoagulation therapy are diverse and should not be generalized.
• Healthcare systems must incorporate patient-centered values into anticoagulation management strategies.
