Comparative study of the B-SAQ, OAB-V8 and OAB-V3 questionnaires as screening tools for overactive bladders in clinical practice.

To compare the capacity shown by 3 self-assessment questionnaires validated in Spanish (B-SAQ, OAB-V8 and OAB-V3) for the screening of patients with overactive bladder (OAB) in clinical practice.

A noninterventional observational study was conducted of men and women older than 30 years evaluated in primary care consultations. The clinical diagnosis of OAB was conducted through a case history review, physical examination, urine analysis, ultrasonography and voiding diary. The presence of coping strategies and discomfort was investigated. The differential diagnosis was established in patients with symptoms not due to OAB. We assessed the correlation between the clinical tests and diagnosis (kappa <.4 poor; .4-.6 moderate; >.6 good; >.8 excellent) and ROC curves to define the capacity to screen the assessed questionnaires.

A total of 411 patients were investigated. OAB was detected in 207 (50.4%) patients, other causes for the lower urinary tract symptoms were detected in 63 (15.3%), and 141 (34.3%) patients had no diagnosis. The voiding diary suggested OAB in 197 (47.9%) patients. The correlation between the clinical diagnosis and the diagnosis based on the voiding diary was .702. The correlation between the clinical diagnosis and B-SAQ, OAB-V8 and OAB-V3 was .59, .673 and .732, respectively. The area under the curve (AUC) was .799 for B-SAQ; .837 for OAB-V8 and .867 for OAB-V3 (OAB-V3 vs. OAB-V8, P=.02; OAB-V3 vs. B-SAQ, P<.0001). The AUC for the voiding diary was .852 (OAB-V3 vs. diary, P=.47).

OAB-V3 is a simple questionnaire with excellent performance for screening OAB in a specific population and that is superior to the OAB-V8 and B-SAQ. The accuracy of the voiding diary for the same indication is equivalent to that of the OAB-V3 in our setting.
