The predictive value of ePAQ in the urodynamic diagnoses-A prospective cohort study.

AIMS: To assess whether the electronic Personal Assessment Questionnaire-Pelvic Floor (ePAQ-PF) had accuracy in predicting the urodynamic diagnoses of Detrusor Overactivity (DO) and/or Urodynamic Stress Incontinence (USI).

METHODS: Tertiary urogynaecology unit linked to an academic university teaching hospital. Consecutive women who presented with lower urinary tract symptoms (LUTS) and were booked to have urodynamic studies. Women completed an ePAQ-PF prior to having urodynamics (UDS) by clinicians who were blinded to the ePAQ-PF results while conducting this procedure. Receiver Operating Characteristics (ROC) curves were constructed for predictive accuracy of overactive bladder (OAB) score in DO and of stress urinary incontinence (SUI) score in USI. Prospective cohort study designed to meet the requirements of the standards for reporting of diagnostic accuracy (STARD).

RESULTS: 390 women with a mean age of 54.2 (range 21-92) years were recruited. The majority (n = 294; 75%) were White Caucasian and had two children (n = 157; 40.3%). Of them, 67.2% (n = 262) had DO and USI was confirmed in 21.5% (n = 84). The area under the ROC curve for DO was 0.704 (95% confidence interval 0.650-0.759) and for USI it was 0.731 (95% confidence interval 0.652-0.778).

CONCLUSIONS: The OAB and SUI scores on the ePAQ-PF demonstrated that they are fair predictors in diagnosing DO and USI. As the OAB and SUI score on ePAQ-PF increased so did the likelihood of DO (up to a score of 75) and USI on UDS.
