Abstract

Purpose

The overactive bladder symptom score (OABSS) consists of 4 questions regarding OAB symptoms. The aim of this study was to develop Korean version of the OABSS from the original Japanese version, with subsequent linguistic validation.

Methods

Between February and May 2008, the translation and linguistic validation process was performed as follows: a forward translation, reconciliation, backward translation, cognitive debriefing, and final proofreading.

Results

A forward translation from the original version of the OABSS to the Korean language was carried out by 2 native Korean speakers, who were also fluent in Japanese. Reconciliation was made after review of both translations by a panel consisting of both translators and one of the authors. Another bilingual translator who had never seen the original version of the OABSS carried out a translation of the reconciled version back into Japanese, and the original and backward-translated versions were subsequently compared. After discussion of all discrepancies between both versions by the panel, a second Korean version was produced. During cognitive debriefing, 5 outpatients with OAB reported that each question of the Korean version was significant and appropriate for their symptoms. However, 2 patients said that some parts of the questions or instructions were not clear or were not easy to understand. According to the cognitive debriefing, some words and phrases were revised into more understandable expressions.

Conclusions

A Korean version of the OABSS was developed and linguistic validation was performed. Further studies are needed to assess the reproducibility and validity of the questionnaire in Korean populations.

Symptom assessment tool for overactive bladder syndrome--overactive bladder symptom score.

Masayuki Takeda, Hidehiro Kakizaki, Osamu Yamaguchi … (2006)

Overactive bladder (OAB) is a common symptom syndrome with urgency, urinary frequency, and urgency incontinence. To collectively express OAB symptoms, we developed the overactive bladder symptom score (OABSS). Four symptoms--daytime frequency, nighttime frequency, urgency, and urgency incontinence--were scored. The weighing score was based on a secondary analysis of an epidemiologic database. Psychometric properties were examined in five patient groups: OAB (n = 83), asymptomatic controls (n = 34), stress incontinence (n = 29), benign prostatic hyperplasia (n = 28), and other diseases with urinary symptoms (n = 26). The maximal score was defined as 2, 3, 5, and 5 for daytime frequency, nighttime frequency, urgency, and urgency incontinence, respectively. The sum score (OABSS 0 to 15) was significantly greater in the patients with OAB (8.36) than in the other patient groups (1.82 to 5.14). The distribution of the OABSS showed a clear separation between those with OAB and asymptomatic controls. The OABSS correlated positively with the individual scores (Spearman's r = 0.10 to 0.78) and quality-of-life scores assessed by the King's Health Questionnaire (Spearman's r = 0.20 to 0.49). The weighted kappa coefficients were 0.804 to 1.0 for each symptom score and 0.861 for OABSS. The posttreatment reduction in the OABSS was consistent with the global impression of patients of the therapeutic efficacy. The OABSS, the sum score of four symptoms (daytime frequency, nighttime frequency, urgency, and urgency incontinence), has been developed and validated. OABSS may be a useful tool for research and clinical practice.

National community prevalence of overactive bladder in the United States stratified by sex and age.

Karin Coyne, Chris C Sexton, Vasudha Vats … (2011)

To estimate the prevalence of and bother associated with overactive bladder (OAB) in adults aged ≥40 years in the United States, using current International Continence Society definitions. Internet-based panel members were selected randomly to participate in EpiLUTS, a cross-sectional, population-representative survey. Participants used Likert scales to rate how often they experienced individual lower urinary tract symptoms during the previous 4 weeks and how much bother they experienced. Based on responses to questions regarding urgency and urgency urinary incontinence, OAB symptoms were categorized as occurring at least "sometimes" or at least "often." Symptom bother was categorized as at least "somewhat" or at least "quite a bit." The response rate was 59.6%, with a final sample of 9416 men and 10,584 women. Prevalence of OAB symptoms at least "sometimes" was 27.2% and 43.1% for men and women, respectively; prevalence of OAB at least "often" was 15.8% and 32.6%, respectively. Among men with OAB symptoms at least "sometimes," 60.0% were bothered at least "somewhat" and 27.8% were bothered at least "quite a bit." Among women, bother rates were 67.6% and 38.9%, respectively. Among respondents with OAB at least "often," 67.8% and 38.2% of men and 73.0% and 47.1% of women reported being bothered at least "somewhat" and at least "quite a bit," respectively. We estimate that 29.8 million adults aged ≥40 years in the United States have bothersome OAB symptoms. Bothersome OAB symptoms are highly prevalent among men and women aged ≥40 years in the United States. Copyright © 2011 Elsevier Inc. All rights reserved.

A systematic review and meta-analysis of randomized controlled trials with antimuscarinic drugs for overactive bladder.

Stefano Cavalleri, A S Secco, Giacomo Novara … (2008)

Anticholinergic drugs are commonly used in patients with overactive bladder (OAB) who do not achieve symptom relief and quality of life improvement with conservative management. Several drugs, with different doses, formulations, and routes of administration are currently available, making the choice quite difficult. To evaluate efficacy and safety of different doses, formulations, and route of administration of the available anticholinergic drugs. A systematic review of the literature was performed in August 2007 using Medline, Embase, and Web of Science. Efficacy (micturitions per 24h, volume voided per micturition, urgency urinary incontinence episodes per 24h, incontinence episodes per 24h) and safety (mainly, adverse events and withdrawal rates) end points were evaluated in the randomized control trials (RCTs) assessing the role of anticholinergic drugs in non-neurogenic OAB. Meta-analysis of RCTs was conducted using the Review Manager software 4.2 (Cochrane Collaboration). Our systematic search identified 50 RCTs and three pooled analyses. Tolterodine immediate release (IR) had a more favorable profile of adverse events than oxybutynin IR. Regarding different dosages of IR formulations, dose escalation might yield some limited improvements in the efficacy but at the cost of significant increase in the rate of adverse events. In the comparisons between IR and extended-release (ER) formulations, the latter showed some advantages, both in terms of efficacy and safety. With regard to the route of administration, use if a transdermal route of administration does not provide significant advantage over an oral one. Many of the available RCTs have good methodological quality. ER formulations should be preferred to the IR ones. With regard to IR formulations, dose escalation might yield some improvements in the efficacy with significant increase in the AE. More clinical studies are needed to indicate which of the drugs should be used as first-, second-, or third-line treatment.
