Frequency of attendance at anticoagulant clinics

Area of Science:

• Cardiology
• Pharmacology
• Health Services Research

Background:

• Clinic attendance frequency for long-term anticoagulant patients varies significantly across healthcare centers.
• Current recommendations suggest shorter intervals than the 3-month monitoring policy at this hospital for patients with good anticoagulant control.

Purpose of the Study:

• To assess the safety and efficacy of a 3-month clinic attendance interval for long-term anticoagulant patients with a history of good anticoagulant control.
• To identify a subgroup of patients suitable for extended monitoring intervals.
• To evaluate the potential cost implications of adjusting monitoring frequency.

Main Methods:

• Retrospective analysis of 461 long-term anticoagulant patients' clinic visit data over one year.
• Examination of anticoagulant control, specifically the British ratio, for patients seen at 3-month intervals.
• Categorization of patients based on visit frequency over the last 5 visits.

Main Results:

• 46% of patients were monitored exclusively at 3-month intervals over the last 5 visits.
• These patients demonstrated excellent anticoagulant control, with 88% of visits falling within the British ratio range of 2.0-4.0.
• The findings suggest a potential for safe extended monitoring in a subset of patients.

Conclusions:

• A significant subgroup of chronic anticoagulant patients with excellent control can be safely monitored every 3 months.
• Implementing 3-month monitoring for this subgroup has considerable cost-saving implications for healthcare services.
• This study supports personalized monitoring strategies in long-term anticoagulation management.
