Mensuração do time in therapeutic range em um ambulatório de anticoagulação

Abstract

Identify the average TTR in a anticoagulation clinic, using warfarin. It is a descriptive observational study conducted in the Anticoagulation Clinic of the University Hospital over a period of four months. The measurement of TTR occurred through the use of Rosendall method, from a historical series of results of the examination ratio normalized International ( RNI ) . Also, measuremented the degree of satisfaction with the clinic, we opted for the application of a structured questionnaire , not validated. Most patients were male, with an indication of anticoagulation for more than one year and motivated by the presence of atrial fibrillation. Although the study has identified that the user satisfaction regarding the services offered at the clinic was mostly positive (95.7%) , this does not mean that the target therapeutic range was being achieved . The TTR sample was around 54.62 %. The value of TTR average below 60% suggests the need to implement strategies that promote more adherence and understanding of the treatment.
