ABSTRACT To compare the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) with the Incontinence Severity Index (ISI), and to propose intervals for four severity levels of ICIQ-UI SF.
Cross-sectional, Internet-based study of 1,812 women responding to a general health questionnaire. Four severity levels for the ICIQ-UI SF scores were constructed by iteratively adjusting the ranges for these levels until maximum Kappa scores were obtained when cross-tabulated with the ISI in a random sample of half of the women with urinary incontinence. Using these intervals, weighted Kappa was calculated for the remaining women as a validation process.
Three hundred forty-three women had urinary incontinence, and completed the ISI and the ICIQ-UI SF. A high correlation between the ISI and ICIQ-UI SF scores with versus without the QoL item was found (Spearman's rho = 0.62, P < 0.01 vs. rho = 0.71, P < 0.01, respectively). Maximum Kappa with quadratic weighting was obtained for the following scale for the ICIQ-UI SF: slight (1-5), moderate (6-12), severe (13-18) and very severe (19-21) (Kappa = 0.61), and without the QoL item: slight (1-3), moderate (4-5), severe (6-9) and very severe (10-11) (Kappa = 0.71) in the development sample. Correspondingly, for the validating sample, maximum Kappa with quadratic weighting was 0.61 and 0.74.
A high correlation between the ICIQ-UI SF and the ISI was found. The ICIQ-UI SF may be divided into the following four severity categories: slight (1-5), moderate (6-12), severe (13-18) and very severe (19-21). Neurourol. Urodynam. 28:411-415, 2009. (c) 2009 Wiley-Liss, Inc.

Les résultats du score ICIQ-IU SF ont été donnés selon la classification proposée A.C. Pizzoferrato et al. par Klovning et al. regroupant les scores en IU légère, IU modérée, IU sévère et IU très sévère [14]. Les critères d'inclusion de notre population étaient les femmes nullipares de plus de 18 ans, sachant lire et écrire le français. "

    ABSTRACT: Aims To assess the prevalence of urinary incontinence (UI) in a population of young nulliparous women and the effectiveness of self-perineal exercises in symptomatic women. Material Three hundred and fifteen nulliparous students from French secondary establishments answered through a secure website, created for the study, an anonymous questionnaire about UI. The questionnaire included validated symptom scores (International Consultation on Incontinence Questionnaire-Short Form, ICIQ-UI SF) and quality of life (Contilife). Women who reported UI were asked to perform a self-perineal rehabilitation program for 8 weeks. A second questionnaire was completed after reeducation to assess the evolution of their UI. Results Among the 315 respondents, 92 women (29.2%) reported UI. The mean age was 23.0 (± 4.4) years in the continent group and 22.9 (± 3.6) years in the incontinent group. Only 24 of the 92 women with UI (26.1%) completed the reeducation program with a significant improvement in UI and quality of life (QoL). Conclusion UI is a common disorder in young nulliparous women. Perineal self-exercises without the intervention of a professional could help to improve the disorders. Level of evidence 5.

    • "Moreover, storage (questions 2, 4, and 7) and voiding (questions 1, 3, 5, and 6) subscores were provided [18]. The severity of urinary incontinence was graded as suggested by Klovning et al [29]. Specifically, patients with a ICIQ-UI SF score of 0 were considered fully continent; patients with scores ranging from 1 to 5, 6 to 12, 13 to 18, and 19 to 21 defined slight, moderate, severe, and very severe incontinence, respectively.

    ABSTRACT: Orthotopic bladder reconstruction is the preferred method of urinary diversion following radical cystectomy (RC). Several papers reported functional data of different orthotopic neobladders, although to date, no one has used validated questionnaires. To evaluate the midterm functional results in a contemporary series of patients undergoing RC and vescica ileale Padovana (VIP) orthotopic neobladder by applying a set of validated questionnaires. We conducted a cross-sectional study at a single academic centre. We included RC and VIP orthotopic techniques for bladder transitional cell carcinoma. The American Urological Association Symptom Index (AUA-SI), the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF), and the five-item version of the International Index of Erectile Function (IIEF-5) were used to evaluate functional outcomes. All 113 patients who were alive and disease free at 44-mo follow-up were evaluated. Sixteen patients (13%) were on clean intermittent catheterisation (CIC). The median AUA-SI score of the 97 voiding patients was 9 (interquartile range [IQR]: 4.5-16). Specifically, 48.5%, 40.2%, and 11.3% of the patients had mild, moderate, or severe lower urinary tract symptoms (LUTS), respectively. American Society of Anaesthesiologists class (odds ratio [OR]: 9.0; p=0.03) and body mass index (OR: 1.5; p=0.023) were independent predictors of the need for CIC, while only patient age at the time of surgery (OR: 0.920; p=0.01) was predictive of LUTS severity. The median ICIQ-UI SF score was 6 (IQR: 3-10). Twenty patients (17.7%) were fully continent, while 31.9%, 35.4%, and 15% had slight, moderate, and severe incontinence, respectively. About 90% of the patients during the day and 80% during the night used no pad or only a safety pad. Most of the patients leaked when asleep. No variable was predictive of return to continence. Finally, roughly 20% of the male patients were potent, having an IIEF-5 score ≥17. We reported midterm functional outcomes following RC and VIP neobladder using validated questionnaires. On the whole, the results are encouraging. However, in the absence of patient self-completed questionnaires, functional outcomes may be significantly overestimated.

    ABSTRACT: In this article, we describe the state of the art and directions of current development and research with respect to the inclusion of medical narratives in electronic medical-record systems. We used information about 20 electronic medical-record systems as presented in the literature. We divided these systems into 'classical' systems that matured before 1990 and are now used in a broad range of medical domains, and 'experimental' systems, more recently developed and, in general, more innovative. In the literature, three major challenges were addressed: facilitation of direct data entry, achieving unambiguous understandability of data, and improvement of data presentation. Promising approaches to tackle the first and second challenge are the use of dynamic data-entry forms that anticipate sensible input, and free-text data entry followed by natural-language interpretation. Both these approaches require a highly expressive medical terminology. How to facilitate the access to medical narratives has not been studied much. We found facilitating examples of presenting this information as fluent prose, of optimising the screen design with fixed position cues, and of imposing medical narratives with a structure of indexable paragraphs that can be used in flowsheets. We conclude that further study is needed to develop an optimal searching structure for medical narratives.
