ABSTRACTBackground: The World Health Organization approved the International Prostate Symptom Score (IPSS) in 1992 as an instrument for evaluating lower urinary tract symptoms in populations living in industrialized countries. However, there are populations for which the questionnaire is complicated, producing false results.
Objetive: To compare the IPSS with the Visual Analogue Scale (VAS-GEA) in patients with lower urinary tract symptoms.
Materials and Methods: An analytic, comparative, cross-sectional study was conducted at the Hospital General Dr. Manuel Gea González within the time frame of March and July 2016. Men above 45 years of age with lower urinary tract symptoms were evaluated through the IPSS and the VAS-GEA, the latter of which was developed together with specialists in Phoniatrics and Graphic Design. Both instruments were applied to each patient, registering the sociodemographic variables, accuracy, and response time. The 2 test was employed for the continuous variables and the Student’s t test for the distribution of means. The Wilcoxon test was used to compare the median of the two samples and determine their differences. The results were analyzed using the SPSS program (version 22.0, IBM).
Results: The study included 121 men with a mean age of 67 years and a mean educational level of 7 years. Thirty-five percent of the patients were unemployed and 8% spoke an indigenous language. Fifty-four patients (40%) asked for help in answering the IPSS due to visual or socio-intellectual limitations, whereas only 14 patients (11%) asked for help in answering the VAS-GEA, with 87% completing it (2:11.68, p ‹ 0.05). The mean time for completing the IPSS was 280 seconds, compared with 170 seconds for the VAS-GEA (Student’s t test: 19.64, p ‹ 0.05).
Conclusions: The VAS-GEA is proposed as an alternative to the IPSS for evaluating lower urinary tract symptoms in patients that have intellectual, linguistic, academic, or sensory limitations.
