Objective:
To develop and validate a simple patient questionnaire for the detection of overactive bladder (OAB).
Design:
An open, non-randomized multicentre study.
Setting:
A pilot study (n = 133) was conducted to bring forward five questions from initially 14 questions, for detection of OAB. These five questions were subject to further validation in the main study (n =520).
Subjects:
531 adults responding to a newspaper advertisement regarding symptoms of OAB and patients seeing a physician for other reasons were attending 28 general practitioners.
Main Outcome Measures:
Agreement rate, sensitivity, and specificity.
Results:
The agreement rate between the patients' own diagnosis based on the patient questionnaire, and the physicians' diagnosis based on medical history, urine analysis, and micturition chart, was 0.78 (kappa =0.89). Sensitivity and specificity were 0.98 and 0.90, respectively.
Conclusion:
The validated questionnaire may become a useful tool to decide whether a patient has overactive bladder. The questionnaire corresponds well with the physicians' diagnosis.
