In developing countries, education to health-care professionals is a cornerstone in the battle against neglected tropical diseases (NTD). Studies evaluating the level of knowledge of medical students in clinical and socio-demographic aspects of NTD are lacking. Therefore, a cross-sectional study was conducted among students from a 7 year-curriculum medical school in Peru to assess their knowledge of NTD by using a pilot survey comprised by two blocks of 10 short questions. Block I consisted of socio-demographic and epidemiological questions whereas block II included clinical vignettes. Each correct answer had the value of 1 point. Out of 597 responders (response rate: 68.4%), 583 were considered to have valid surveys (male:female ratio: 1:1.01; mean age 21 years, SD ± 2.42). Total knowledge showed a raising trend through the 7-year curriculum. Clinical knowledge seemed to improve towards the end of medical school whereas socio-demographic and epidemiological concepts only showed progress the first 4 years of medical school, remaining static for the rest of the curricular years (p = 0.66). Higher mean scores in socio-demographic and epidemiological knowledge compared to clinical knowledge were seen in the first two years (p<0.001) whereas the last three years showed higher scores in clinical knowledge (p<0.001). In conclusion, students from this private medical school gained substantial knowledge in NTD throughout the career which seems to be related to improvement in clinical knowledge rather than to socio-demographic and epidemiological concepts. This study assures the feasibility of measuring the level of knowledge of NTD in medical students and stresses the importance of evaluating education on NTD as it may need more emphasis in epidemiological concepts, especially at developing countries such as Peru where many people are affected by these preventable and treatable diseases.
RESUMENObjetivos: Determinar la calidad del control de la anticoagulación oral y los posibles factores asociados al tiempo de rango terapéutico. Material y métodos: Estudio retrospectivo con grupo control y exploración de posibles variables, realizado en pacientes ≥65 años con fibrilación no valvular e indicación de anticoagulación del Hospital Cayetano Heredia entre el 2011-2013. Se determinó el tiempo de rango terapéutico (TRT) por el método de Rosendaal y se consideró control óptimo (TRT ≥60%) y subóptimo (TRT <60%). Se realizó análisis univariado para los factores. Resultados: La mediana de la edad fue 82,23 años, 74 (51,75%) fueron mujeres. Ciento cuarenta pacientes tuvieron indicación de anticoagulación, 94 (67,14%) iniciaron warfarina, 28 (19,72%) tuvo control óptimo y 66 (46,48%) subóptimo. La edad ≥75 años (OR 25,5; IC: 7,8), no bajo grado de instrucción (OR 8; IC 3,61), ≥3 comorbilidades (OR 4,5; IC 2,33-9,39), discontinuidad terapéutica (OR 2,75; IC 1,44-5,52) y polifarmacia (OR 4,2; IC 2,16-8,80) se asociaron con control subóptimo, mientras que independencia funcional (OR 4,3; IC 2,16-9,47), no deterioro cognitivo (OR 7,8; IC 3,19) y género femenino (OR 3; IC 1,62-5,81) al control óptimo. Conclusiones: Un gran porcentaje de pacientes con indicación de ACO y con bajo riesgo de sangrado no iniciaron terapia anticoagulante; y el 50% de quienes la iniciaron, tuvo un control subóptimo. Los pacientes de mayor edad, con mayor comorbilidad y el uso de múltiples medicamentos se asociaron con control subóptimo; mientras que el género femenino y la independencia funcional se asociaron con control óptimo.PALABRAS CLAVE: Fibrilación atrial, warfarina, anciano, accidente cerebrovascular.

Methods: Retrospective study with a control group in patients ≥65 years old with nonvalvular atrial fibrillation who had indication for oral anticoagulation at Hospital Cayetano Heredia from 2011 to 2013. Time to therapeutic range (TTR) was determined by the Rosendal´s method, an optimal control was defined as TTR ≥60%. A multivariate analysis was performed. Results: Median age was 82.23 years; 74 (51.75%) were females; 140 patients had indication for anticoagulation; 94 (67.14%) started warfarin; 28 (19.72%) had optimal control and 66 did not (46.48%). Age ≥ 75 years (OR 25.5; and no low degree of instruction (OR
