BACKGROUND: The aim of this study was to demonstrate that the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) tool can be applied for a factual score determining urinary incontinence in the Katz-6 Scale, and it is effective to identify score 2 from score 3.
METHODS: Functional capacity of 63 patients (14 M, 49 F aged from 70 to 99 years old) was evaluated with a Mini Mental State Examination (MMSE), Katz Index for Activities of Daily Living, and ICIQ-UI-SF questionnaire. Mean comparative analysis was performed. ICIQ-UI-SF scores were then entered as variables. These data observed in Katz continence item scored 2 and Katz continence item scored 3 were compared in a combined box-and-whisker and dot plot. Sensitivity and specificity of each variable were tested and results were evaluated using a receiver operating characteristic (ROC) curve. The best variable (ICIQ-UI-SF Score) was retained as a breach permitting to distinguish patients to be scored 2 or 3 over continence Katz item.
RESULTS: Statistical analysis demonstrated significant difference between the sample of Katz continence item scored 2 and the sample of Katz continence item scored 3 over the ICIQ-UI-SF Score and the Katz global Score, but the difference was not significant concerning the MMSE Score. Using ROC analysis, we compared the discriminant power of the ICIQ-UI-SF Score for continence Katz item Score. Criterion values and coordinates of the ROC curve were studied and the ICIQ-UI-SF score of 13 was considered the best one.
CONCLUSIONS: We demonstrated that the best variable (ICIQ-UI-SF Score) to retain as a breach permitting to distinguish patients to be scored 2 or 3 over continence Katz item is 13.
