Resumen
Introducción: La hiperplasia prostática benigna es una enfermedad progresiva multifactorial que repercute en la calidad de vida. El Índice Internacional de Síntomas Prostáticos (IPSS) es importante en la evaluación, pero se han descrito dificultades en su aplicación. La Escala Visual de Síntomas Prostáticos (VPSS) ha sido validada en varios estudios demostrando correlación positiva con el IPSS. Objetivo: Evaluar la validez de constructo de la escala Visual de Síntomas Prostáticos comparándola con el Índice Internacional de Síntomas Prostáticos en pacientes con Hiperplasia Prostática Benigna. Materiales y métodos: Estudio observacional, descriptivo, correlacional, transversal, no experimental, en el Hospital Teodoro Maldonado Carbo de julio a octubre 2020 en pacientes con HPB. En 114 pacientes se aplicaron los cuestionarios VPSS e IPSS. Se utilizó la prueba de chi-cuadrado para evaluar factores asociados al llenado de cuestionarios, para la correlación se usó la prueba no paramétrica de Spearman, se aceptó como estadísticamente significativo un valor de p < 0,05. Resultados: De un total de 114 sujetos, 99 (86,8%) solicitaron ayuda en IPSS y 10 (8,8%) en VPSS. Hubo asociación entre la necesidad de ayuda en IPSS y el nivel de instrucción (p<0,0001), pero no para VPSS (p=0,24). Para completar IPSS necesitaron una mediana de tiempo de 2 minutos 30 segundos y de 48 segundos para VPSS. La correlación de Spearman entre el puntaje total de IPSS y VPSS fue de 0,89 (p<0,001). Conclusiones: Se encontró una correlación positiva estadísticamente significativa entre el VPSS y el IPSS sin embargo hubo una concordancia débil al categorizar. Palabras claves: VPSS, IPSS, hiperplasia prostática benigna
Introduction: Benign Prostatic Hyperplasia is a multifactorial progressive disease that affects the quality of life. The International Prostate Symptom Score (IPSS) is important in the evaluation, but some difficulties in its application have been described. The Visual Prostate Symptom Score (VPSS) has been validated in several studies showing a positive correlation with the IPSS. Objective: To evaluate the construct validity of the Visual Prostate Symptom Score, comparing it with the International Prostate Symptom Score in patients with Benign Prostatic Hyperplasia. Methods and Materials: Observational, descriptive, correlational, cross-sectional and nonexperimental studies at the Teodoro Maldonado Carbo Hospital, from July through October 2020, in patients with BPH. The VPSS and IPSS questionnaires were applied to 114 patients. The chi-square test was used to evaluate factors associated with the patients’ completion of questionnaires, the non-parametric Spearman test was used for the correlation, a value of p <0.05 was accepted as statistically significant. Results: From a total of 114 subjects, 99 (86.8%) requested assistance with IPSS and 10 (8.8%) with VPSS. With IPSS, there was an association between the need for assistance and the level of education (p <0.0001), but not with VPSS (p = 0.24). A median time of 2 minutes 30 seconds to complete IPSS and 48 seconds for VPSS. The Spearman correlation between the total IPSS and VPSS score was 0.89 (p <0.001). Conclusions: A statistically significant positive correlation was found between the VPSS and the IPSS however there was a weak concordance when categorizing. Key words: VPSS, IPSS, Benign Prostatic Hyperplasia.
