Background:
Ventricular assist devices require anticoagulation to reduce thrombosis risk. Nurse-driven unfractionated heparin monitoring protocols have been validated for various indications, although data in patients with ventricular assist devices are lacking.
Objective:
To evaluate a nurse-driven protocol for managing unfractionated heparin therapy in stable patients with ventricular assist devices.
Methods:
This was a retrospective analysis of adult patients with ventricular assist devices requiring unfractionated heparin therapy, divided into 2 groups: before and after protocol implementation. The primary outcome was time to first therapeutic activated partial thromboplastin time.
Results:
Each group included 29 patients. There was no difference between the preintervention and postintervention groups in time to therapeutic activated partial thromboplastin time (25 vs 23 hours, P = .95) or proportion of patients with therapeutic activated partial thromboplastin time within the first 24 hours (45% vs 34%, P = .42). Suspected pump thrombosis and bleeding events were similar in the 2 groups.
Conclusion:
A nurse-driven heparin monitoring protocol was similar in time to therapeutic activated partial thromboplastin time compared with provider-driven monitoring and adjustments in patients with ventricular assist devices.
