Primary care anticoagulant management using near patient testing

Area of Science:

• Primary Care Medicine
• Clinical Pathology
• Pharmacology

Background:

• Increasing indications for anticoagulant therapy necessitate a shift from hospital to primary care settings.
• New models for anticoagulant services are required to meet growing patient needs.
• Primary care settings offer a potential solution for decentralized anticoagulant management.

Purpose of the Study:

• To pragmatically evaluate the validity and effectiveness of primary care anticoagulant management.
• To assess the utility of near-patient testing devices in rural primary care settings.
• To determine the feasibility of managing anticoagulation therapy outside of traditional hospital-based services.

Main Methods:

• Twelve CoaguCheck monitors were distributed to 16 rural general practices.
• Practices collected data on eligible patients undergoing anticoagulant therapy from September 1998 to April 1999.
• Weekly blood samples were sent to a regional laboratory for parallel testing to validate near-patient results.

Main Results:

• Data from 122 patients across nine practices were analyzed.
• The CoaguCheck monitor demonstrated validity for anticoagulant management (r2 = 0.00).
• 88% of International Normalized Ratio (INR) tests were within the desired therapeutic range, with 48.3% achieving this target.

Conclusions:

• The study confirms the validity of using the CoaguCheck monitor for anticoagulant management in primary care.
• Near-patient testing is a viable approach for managing anticoagulation therapy in rural settings.
• Decentralizing anticoagulant management to primary care is feasible and effective.
