Description
Summary:Objective. To determine the degree of knowledge about warfarin treatment in patients with atrial fibrillation or with mechanical prosthetic valves. Materials and methods. Descriptive, observational, cross-sectional study. The OAK test was applied to all adult patients with a diagnosis of atrial fibrillation or with mechanical prosthetic valves treated with warfarin, who attended the hematology consultation from May 17 to November 10, 2022, at the “Instituto Nacional Cardiovascular Carlos Alberto Peschiera Carrillo”. Results. A total of 150 patients participated, 64% were male, with a mean age of 60.3 ± 15 years, 45.3% with a diagnosis of atrial fibrillation and 54.7% with mechanical prosthetic valves. The mean OAK test score was 44.4% (8.4/19), only 6% (n=9) achieved a satisfactory score ≥75.0%, the percentage of correct answers according to dimensions was: 68 % in forms of use, 39.3% in interactions and complications and 41.1% in INR control. A 40.7% did not understand the meaning of the term INR and 81.3% did not know their optimal values. Conclusions. The patient’s degree of knowledge about warfarin treatment was inadequate; both in its use, interactions and complications. Considering that it is a difficult drug to use, due to its narrow therapeutic window and its multiple interactions, inadequate knowledge of its use may contribute to inappropriate anticoagulation. Objetivo. Determinar el grado de conocimiento acerca del tratamiento con warfarina en pacientes con fibrilación auricular o portadores de válvulas protésicas mecánicas. Materiales y métodos. Estudio descriptivo, observacional y de corte transversal. Se incluyó a todos los pacientes adultos con diagnóstico de fibrilación auricular o portadores de válvulas protésicas mecánicas tratados con warfarina, que acudieron a la consulta de hematología desde el 17 de mayo hasta el 10 de noviembre de 2022, en el “Instituto Nacional Cardiovascular Carlos Alberto Peschiera Carrillo”, a quienes se aplicó el test OAK. Resultados. Participaron 150 personas, el 64% fueron varones, con una edad promedio de 60,3 ± 15 años, el 45,3% con diagnóstico de fibrilación auricular y el 54,7% portadores de válvulas protésicas mecánicas. El puntaje promedio del test OAK fue 44,4% (8,4/19), solo el 6% (n=9) logró un puntaje satisfactorio ≥75,0%, el porcentaje de respuestas correctas según dimensiones fue: 68 % en formas de uso, 39,3% en interacciones y complicaciones y 41,1% en control del INR. El 40,7%
