Determining patient preferences in the treatment of medication-refractory overactive bladder.

Overactive bladder (OAB) is often suboptimally addressed by behavioral or pharmacological treatments. Less than 15% of patients choose to pursue advanced OAB therapy (sacral nerve stimulation [SNS], percutaneous tibial nerve stimulation [PTNS], and bladder onabotulinum toxin type-A [BTX-A]). We seek to better understand which factors are most important to patients when choosing a third-line therapy.

We developed a conjoint analysis survey that included five attributes of the third-line options for OAB (SNS, PTNS, and BTX-A). We administered the survey to new patients with urinary incontinence at two institutions. A hierarchical Bayes random effects regression analysis was used to determine the relative importance of the attributes. A choice simulator was used to model which third-line treatment options patients preferred. We followed patients to see if they pursued their predicted treatment.

A total of 108 patients completed the study of whom 89% were women. There was representation from all age groups. The most important attributes of decision-making were the frequency of future procedures, the risk of catheterization, and the need for a device. On market simulation, SNS was the preferred treatment option (47%), followed by PTNS (29%) and BTX-A (14%). Only 10% of patients did not find any treatment option acceptable.

Frequent follow-up, risk of catheterization, and the need for a device were the most important attributes when making a decision on third-line OAB therapy. On market simulation, SNS is the preferred treatment for all age groups though the ultimate choice in third-line therapy may be affected by external factors.
