Validation of the International Prostate Symptom Score in Chinese males and females with lower urinary tract symptoms.

ABSTRACT: OBJECTIVES: To evaluate the translation of the IPSS (Hong Kong Chinese version 1) and to assess the applicability, validity, reliability and sensitivity of the instrument in both males and females with LUTS in Chinese population. METHODS: The translation of the IPSS (Hong Kong Chinese version 1) was reviewed through back translation. Modifications were made, resulting in the development of The IPSS (Hong Kong Chinese version 2). The content validity was assessed by contend validity index. 233 subjects with LUTS were recruited in Hong Kong primary care settings for pilot psychometric testing. The construct validity was assessed by corrected item-total correlation and Pearson's correlation test against ICIQ-UI SF, IIQ-7 and SF-12 v2. The reliability was assessed by the internal consistency (Cronbach's Alpha coefficient) and test -retest reliability (Intraclass correlation coefficient). The Sensitivity was determined by performing known group comparisons by independent T-test. RESULTS: The content validity index for all items could reach 1. Corrected item-total correlation scores were ?0.4 for four symptom questions (feeling of incomplete bladder emptying, intermittency, weak stream and straining). Overall, the total symptom score moderately correlated with ICIQ-UI SF. The quality of life score moderately correlated with the IIQ-7 but weakly correlated with SF-12 v2. Overall, the reliability of the IPSS (Hong Kong Chinese version 2) was acceptable (Cronbach's Alpha coefficient?=?0.71, ICC of the symptom questions =0.8, ICC of the quality of life question =0.7). The symptoms questions and quality of life questions of the IPSS (Hong Kong Chinese versions 2) were sensitive in detecting differences between groups. CONCLUSIONS: The IPSS (Hong Kong Chinese version 2) is a valid, reliable and sensitive measure to assess Chinese females and males with lower urinary tract symptoms. The IPSS quality of life question is more sensitive than the generic quality of life measure to differentiate subgroups.

Project description:The International Consultation on Incontinence Questionnaire-Pediatric Lower Urinary Tract Symptoms (ICIQ-CLUTS) is a 12-item self-administered tool to screen lower urinary tract symptoms (LUTS) in children. The aim of this study is to translate and validate the ICIQ-CLUTS into Spanish (ICIQ-CLUTS-Sp) and to study its psychometric properties. The cross-cultural adaptation of the ICIQ-CLUTS was performed following international recommendations. The psychometric analysis of the ICIQ-CLUTS-Sp was carried out to determine the reliability, validity, and diagnostic accuracy in a sample of 155 children and parents who completed the Spanish version ICIQ-CLUTS. The reliability indicators for the ICIQ-CLUTS-Sp were excellent (Cronbach's alpha was > 0.8 and ICC > 0.9 both for children's and parents' versions). There was a high Pearson r > 0.6 and a high agreement level between children's and parents' answers (ICC > 0.6), except in 4 items. For parents, the standard error of measurement (SEm) was 0.41, and the minimal detectable change (MDC) was 1.14 points. In children, these results were 0.42 and 1.16 points, respectively. Cut-off points greater than 15 points in the parent version or 16 points in the children version have the highest sensitivity and specificity for detecting LUTS. Conclusion: The Spanish version of the ICIQ-CLUTS questionnaire is a valid, reliable, and diagnostically accurate instrument to identify cases of children with LUTS. Therefore, it can be used to screen for lower urinary tract symptoms in Spanish speaking children and/or parents, as well as to monitor the effects of interventions. What is Known: • Lower urinary tract symptoms in children should be assessed multimodally using minimally invasive diagnostic procedures. One way to do this is to use the questionnaire to differentiate these cases in paediatric patients. • A cross-cultural adaptation of the ICIQ-CLUTS questionnaire to Spanish has not yet been done. What is New: • Based on a comprehensive validation methodology, this study highlights that the ICIQ-CLUTSSp questionnaire has good psychometric properties.

Project description:AimsBother attributed to lower urinary tract symptoms (LUTS) drives care-seeking and treatment aggressiveness. The longitudinal relationship of LUTS severity and bother in a care-seeking cohort, however, is not well understood. We aim to conduct a longitudinal evaluation of LUTS severity and bother and identify characteristics of patients with discordant LUTS bother relative to severity.MethodsMen and women with LUTS seeking care at six US tertiary care centers enrolled in the symptoms of lower urinary tract dysfunction research network study. Patients reporting at least one urinary symptom based on the LUTS Tool were prospectively enrolled from June 2015 to January 2017. Correlations were used to assess the relationship between LUTS severity and bother. Discordance scores (ie, the difference between bother and severity) were used to classify patients with high and low bother. Patients were classified as having high or low bother phenotypes if scores were one standard deviation above or below zero, respectively. Repeated measures multinomial logistic regression evaluated characteristics associated with high and low bother phenotypes.ResultsLUTS severity and bother were at least moderately correlated for all symptom items and highly correlated for 13 out of 21 items. Correlations were highest for urgency, and lowest for daytime frequency and urinary incontinence. Odds of being in high bother phenotype were lowest at 3 and 12 months (3 months vs baseline odds ratio [OR] = 0.71, 95% confidence ninterval [CI] = 0.54-0.94; 12 months vs baseline OR = 0.66, 95% CI = 0.48-0.91), and highest for those who endorsed all urgency questions (OR = 3.65, 95% CI = 2.17-6.13). Odds of being in the low bother phenotype were lowest for patients who endorsed all urgency items (OR = 0.33, 95% CI = 0.26-0.42), and all frequency items (OR = 0.68, 95% CI = 0.53-0.88).ConclusionsLUTS severity and bother correlate highly and measurement of both in clinical practice is likely redundant. There are patient factors associated with discordance which may justify additional evaluation.

Project description:BackgroundThe Visual Prostate Symptom Score (VPSS) is used for the assessment of lower urinary tract symptoms (LUTS). It is usually administered by general practitioners (GPs), but in these cases, outcomes do not seem to be reflecting the real conditions of a patient well, with consequent risks of misestimations and misinterpretations. We developed an electronic audiovisual version of VPSS (EPSS), a new symptom scale based on a telemedicine mobile light-based app. The aim of this study is to test and evaluate its reliability.MethodsWe enrolled male patients aged between 50 and 80 years across 24 community-based healthcare facilities in Guangzhou, China. Patients were asked to complete the Chinese version of VPSS and EPSS before consultation with the urology specialists. Patients were divided into two groups based on age. First, we analyzed the rate of full understanding of EPSS using a chi-square test. Then, we analyzed the difference between each score of EPSS, VPSS, and outcomes measured by specialists, used as the reference score (RS). Finally, the outcomes were analyzed with the Spearman test and Bartlett test separately.ResultsSeventy-nine male patients were included (mean age 70.42 years). Patients were divided into two groups: group 1 (>70 years, n = 40) and group 2 (<70 years, n = 39). The full-understanding rates in groups 1 and 2 were 50% and 64.1%, respectively. No significant differences were noted between groups (p = 0.206). A t-test was presented between each question of VPSS, EPSS, and RS. All questions did not display significant differences (p > 0.05); total scores from the three scales had no significant differences in the evaluation of LUTS. We further explored the variations of choices made by patients in different scales. Spearman's test among VPSS, EPSS, and RS showed positive correlations, and coefficients of the total score were 0.92, 0.91, and 0.93 (p < 0.05).ConclusionEPSS can be easily used in a significant number of patients and showed correlation with the VPSS and RS. Moreover, certain items resulted in better performance than VPSS. The results showed that EPSS could be a valuable option for both patients and GPs monitoring LUTS and particularly helpful when teleconsultations are considered, especially during the COVID-19 pandemic.
