Cardiovascular diseases are the leading cause of death in the Russian Federation. Early and effective treatment increases life expectancy and quality of life. Vitamin K antagonists (VKAs) reduce the thrombosis risk in certain patients. In 2018, in the Republic of Tatarstan (RT), an anticoagulant therapy network to monitor coagulation parameters and proper dosing of the drugs was organized, considering the potential risks inherent to this drug group.
OBJECTIVE
To assess the efficacy of the PT anticoagulant therapy network using monitoring of coagulation parameters and VKAs dosing.
MATERIALS AND METHODS
Specialized software «Anticoagulation» was used to organize the activity of the anticoagulant network, which ensures the network functioning and monitoring of coagulation parameters and VKAs dosing. Training for physicians involved in international normalized ratio (INR) monitoring was performed, and patient schools were organized.
RESULTS
Between 2018 and 2019, 4.076 patients taking VKAs were registered in the Anticoagulation program, and 30.431 INR tests were performed. It was shown that the vast majority of patients taking warfarin have atrial fibrillation (51.6% of all patients), followed by patients with artificial heart valves (39.5%), venous thrombosis of various localizations (5.3%), and pulmonary hypertension (0.4%), etc. Time in therapeutic range as a key performance indicators of monitoring efficacy for this patient group increased from 60 to 67% between 2018 and 2019. The average time between INR tests increased from 24 days in 2018 to 26 days in 2019. Complications were recorded in 1.5% of cases, and all of them were mild gingival, time-limited nasal, and subcutaneous bleeding. No mortality or urgent hospital admission due to incorrect dosage of warfarin was reported.
CONCLUSION
The effectiveness of the RT anticoagulant therapy network for patient monitoring and AVK dosing using specialized software was demonstrated. The Anticoagulation software module is considered an effective tool for monitoring patients taking AVKs.
