Protocol-based anticoagulation management for mechanical circulatory support patients can be safe and efficient.

Area of Science:

• Cardiology
• Medical Device Technology
• Patient Care Management

Background:

• Optimal anticoagulation is crucial but challenging for patients with left ventricular assist devices (LVADs).
• Tight anticoagulation control is essential to prevent serious complications like pump thrombosis and bleeding.
• Current management strategies require significant time investment for effective control.

Purpose of the Study:

• To evaluate the efficacy and safety of a nurse coordinator-driven outpatient protocol (NCDOP) for anticoagulation management in LVAD patients.
• To assess the impact of the NCDOP on key anticoagulation metrics and patient safety outcomes.
• To determine if the NCDOP facilitates efficient care delivery for LVAD patients.

Main Methods:

• Retrospective analysis of a single-center quality improvement project.
• Primary outcome: Time in Therapeutic Range (TTR) before and after NCDOP implementation.
• Patient cohort: 47 LVAD patients serving as their own controls.

Main Results:

• No significant change in TTR or hospitalization rates observed post-NCDOP implementation.
• Pre-NCDOP: six major bleeding and two thrombotic events occurred.
• Post-NCDOP: zero major bleeding and zero thrombotic events reported.

Conclusions:

• A nurse coordinator-driven outpatient protocol is a reliable method for managing anticoagulation in LVAD patients.
• The NCDOP facilitates efficient care delivery, potentially improving patient safety.
• Further multicenter studies with larger cohorts are recommended to validate these findings.
