Abstract
Objectives
● To validate the Bladder Control Self-Assessment Questionnaire (B-SAQ), a short screener to assess LUTS / OAB in men.
● Lower urinary tract symptoms (LUTS) and overactive bladder (OAB) are highly prevalent. Case finding tools such as the B-SAQ have been developed to raise awareness of LUTS, possible bladder problems and prompt people to seek treatment.
Patients & Methods
● Prospective, single centre study, urology outpatient setting. N=211.
● All patients completed the B-SAQ and Kings Health questionnaire (KHQ) prior to consultation, and the consulting urologist made an independent assessment of LUTS and need for treatment.
● Psychometric properties of the B-SAQ were analysed.
Results
● 98% of respondents completed all items correctly in less than 5 min.
● Mean B-SAQ scores were 12 and 3.3, respectively for cases (n=101) and controls (n=108) (p<0.00001).
● Good correlation was evident between the B-SAQ and the KHQ.
● The agreement between the individual B-SAQ items and the KHQ symptom severity scale was 86%, 85%, 84% and 79% for frequency, urgency, nocturia and urinary incontinence.
● Using a B-SAQ symptom threshold of ≥ 4 alone had a sensitivity, specificity and positive predictive value of 75%, 86% and 84%, respectively, for detecting LUTS with an area under the curve of 0.88. However, in combination with a bother score threshold of ≥ 1 this changed to 92%, 46% and 86%.
Conclusions
● The B-SAQ is an easy and quick valid case finding tool for LUTS / OAB in men.
● The B-SAQ has the potential to raise awareness of LUTS.
● It appears to be less specific in men compared to women.
● Further validation in a community setting is required.
