- Abstract
The main objective of our study was to carry out a statement of the knowledge and the management of the VKA by the General Practitioners (GPs) of Normandy and to evaluate their experience of the use of DOA with a questionnaire; 471 of the 1951 GPs requested responded. When the INR was stable in a patient affected with atrial fibrillation, the GPs participating dosed it again 4 weeks later, modified the dosage when the INR was below 1.9 or upper 3.2. The risk of stroke was overestimated to 6.2% per year with fluindione and to 31.5% without curative anticoagulation. The mean TTR was overstated to 84%. When the INR was at 4.4, the risk of serious cerebral bleeding was overestimated at 12.4%. 80.26% of the GPs skipped the next dose and 11.25% controlled the INR the day after. So, few GPs used the HAS protocol. After the INR decreased to 3.6, the GPs diminished the dose of 14.62%. 70% of the GPs, responded using only their experience for AVK management. Fluindione was the most to use VKA by 52.7% of them although 24.42% thought it was the most effective. The majority of GPs thought the DOA were a least as effective than the VKA, without being responsible of more bleeding (77.92%) and improved the quality of life of the patients (88.54%). Although the DOA's prescriptions increase, the improvement of the VKA management have to stay a concern for the GPs.
