Overactive bladder syndrome affects a significant share of men and women in Europe, yet population-based prevalence data in Spain—especially in Madrid—have been limited. This cross-sectional study screened consecutive adults over 30 years attending primary care in SW Madrid using the self-administered OAB-V3 questionnaire. Clinical investigation followed Coyne criteria, with assessment of well-being, HRQL, coping behaviors, and labor productivity, plus kappa and ROC analyses for diagnostic accuracy. Results evaluated prevalence, gender and age patterns, and symptom impact.

Centro de Salud Sector III ASSESSMENT OF MALE AND FEMALE PREVALENCE OF OVERACTIVE BLADDER (OAB) IN MADRID (SPAIN) USING A SELF-ADMINISTERED SCREENING QUESTIONNAIRE: ABBREVIATED VERSION OVERACTIVE BLADDER AWARENESS TOOL OAB-V3 . Hypothesis / aims of study Overactive bladder syndrome is a common condition affecting 12-17% of men and women in Europe (1), with prevalence increasing with age. Previous studies in Spain have reported an estimated prevalence of 11.8%(2) but few population-based prevalence surveys have been performed in Spain and none specifically in Madrid. Also the impact of OAB symptoms in aspects of occupational, psychological and social life are lacking in our environment. The abbreviated version Overactive Bladder Awareness Tool OAB-V3 has been validated in Spanish and confirmed a valid tool for the detection of patients with probable OABin the general population in Spain (3) . The primary objective of this study was to assess the prevalence of OAB symptoms inpatients attending general practitioner office in a closed area in Madrid (Spain) . Secondary objective was evaluation of the impact of OAB symptoms on well-being and labor productivity in this population. Study design, materials and methods Cross-sectional observational study carried out at all the primary health centers in a metropolitan town in SW Madrid (Spain) and their referral urology unit in a university hospital. Consecutive male and female subjects (aged over 30 years) aiming to evaluate at least 0.5% of the population of the town were screened were evaluated with self-administered questionnaire OAB-V3 (three questions on symptoms bother related to frequency, urgency and urge-incontinence; each rated 1-5) . Age and gender were recorded. Subjects were classified into less than 3 rate (healthy controls) or equal or more than 3 (suspected OAB) . All subjects with suspected OAB and a similarly balanced population of controls were clinically investigated. Presence or absence of coping strategies and also bothering defining OAB were investigated. Subjects with OAB-V3 >3, coping strategies and bothering were considered probable OAB (Coyne criteria) . Detailed clinical history, physical examination including genital exploration in females and rectal exam in males, urinalysis, bladder and renal sonogram, general well-being scale, PPBC, 33-item OAB-Q and WPAISHP were performed to define the correct clinical diagnosis of OAB or other differential diagnosis and also the impact of OAB on well-being, individual domains and labor productivity. Kappa coefficient between OAB-V3 scale and clinical diagnosis was investigated, and ROC curve analysis was performed. Results OAB-V3 and demographic data from 923 subjects (0 .55% of adult total inhabitants) over 30 years of age was obtained. Mean OAB-V3 value increased with age (p= .0037) and was superior in females than males (p= .03) . Subjects with OAB-V3 >3 were 253 (27 .4%), 92 (36 .4%) males and 161 (63 .6%) females. Their proportion in each decade was 11. 1%(31-40), 24.6%(41-50), 26.9%(51-60), 28.6%(61-70), 32.8%(71-80) and 50%(81-90) . Subjects with OAB-V3 >3, bothering symptoms and coping strategies were 209 (22 .6%), 73 (34 .9%) males and 136 (65 . 1%) females. Their proportion in each decade was 11. 1%(31-40), 17.9%(41- 50), 21.4%(51-60), 25.3%(61-70), 29.8%(71-80) and 44.4%(81-90) (p= .0001) (Figure 1) . Patient

To assess the prevalence of overactive bladder (OAB) symptoms in patients attending general practitioner offices in Madrid.

How did the study screen for probable OAB?

Participants over 30 years completed the self-administered OAB-V3 questionnaire, where scores greater than 3 combined with coping strategies and symptom bother defined probable OAB using Coyne criteria.

What diagnostic performance did OAB-V3 show?

A kappa coefficient of 0.73 was found between definite clinical diagnosis and the OAB-V3 questionnaire, with ROC analysis showing an area under the curve of 0.87.
