Escala Visual Analógica de Función Eréctil Pineda (EVAFEP): una alternativa al Índice Internacional de Función Eréctil (IIEF-5) / The Erectile Function Pineda Visual Analog Scale (EFP-VAS): an alternative to the International Index of Erectile Function (IIEF-5

OBJETIVO: Desarrollar un instrumento visual analógico para diagnosticar a los pacientes con disfunción eréctil, establecer la capacidad de comprensión del mismo en la población y compararlo con la escala «gold standard» en la enfermedad, sentando las bases para su futura validación. MATERIAL Y MÉTODOS: Estudio transversal que incluyó a todos los hombres mayores de 18 años del Servicio de Urología del Hospital Juárez de México cuyo motivo de consulta fue la disfunción eréctil. Los pacientes fueron evaluados utilizando dos herramientas clínicas: el Índice Internacional de Función Eréctil y la Escala Visual Analógica de Función Eréctil Pineda consecutivamente. Las características sociodemográficas de los pacientes incluyeron edad, idioma, nivel educativo, localidad y estado civil. Se valoró la comprensión, el tiempo de respuesta y el grado de disfunción. Las variables cualitativas se analizaron con Chi cuadrado de Pearson χ2 y las cuantitativas con la prueba «U» de Mann-Whitney. RESULTADOS: El registro final incluyó a 227 pacientes, encontrando una edad promedio de 55,6±14 años. La mayoría de la población (94,7%) se comunicaba mediante el idioma español. Existen diferencias estadísticamente significativas entre ambas escalas, en la comprensión, el grado de disfunción, el puntaje final y el tiempo de respuesta, todas con una p de 0,0001. Los pacientes con menor nivel educativo fueron capaces de responder completa y más prontamente el cuestionario Escala Visual Analógica de Función Eréctil Pineda que el Índice Internacional de Función Eréctil, no obstante no podemos asumir absolutamente que lo comprendan mejor. CONCLUSIONES: La Escala Visual Analógica de Función Eréctil Pineda es un prototipo de escala visual que puede utilizarse como alternativa al cuestionario Índice Internacional de Función Eréctil, especialmente en pacientes que presenten limitaciones académicas y lingüísticas

OBJECTIVE: To develop an analog visual instrument to diagnose patients with erectile dysfunction, to establish the ability to understand it in the population and to compare it with the "gold standard" scale for the disease, providing a basis for its future validation. MATERIAL AND METHODS: Cross-sectional study that included all 18 years old men and older, of the urology service of Juarez Hospital of Mexico City, whose reason for consultation was erectile dysfunction. The patients were assessed using two clinical tools: the International Index of Erectile Function and the Erectile Function Pineda Visual Analog Scale consecutively. The sociodemographic features of the patients included age, language, educational level, location and marital status. The comprehension, the response time and the degree of dysfunction were assessed. The qualitative variables were analyzed with Pearson's chi square and the quantitative variables with the Mann-Whitney U test. RESULTS: The final registry included 227 patients, finding an average age of 55.6±14 years. The majority of the population (94.7%) communicated through the Spanish language. There are statistically significant differences between both scales, in the understanding, the degree of dysfunction, the final score and the response time, all with a p=,0001. The patients with lower educational level were able to respond completely and more quickly the Erectile Function Pineda Visual Analog Scale questionnaire than the International Index of Erectile Function. However, we cannot assume that they understand it better. CONCLUSIONS: The Erectile Function Pineda Visual Analog Scale is a prototype of a visual scale that can be used as an alternative to the International Index of Erectile Function questionnaire, especially in patients with academic and linguistic limitations
