A Mobile Application Patient Decision Aid For Treatment Of Overactive Bladder

ObjectiveThe aim of this study was to develop and validate a mobile application patient decision aid (mPDA) for providing treatment options to women with overactive bladder (OAB). MethodsWe performed a mixed methods study. We conducted cognitive interviews to gain insight about treatment decisions for OAB. We then developed an evidence-based mPDA and conducted a prospective cohort study to validate it. Women completed the validated Decisional Conflict Scale. Construct validity was determined by comparing Decisional Conflict Scale scores before and after use of the decision aid. Concurrent validity was assessed by determining the relationship between change in Decision Conflict Scale score and a validated Patient Satisfaction Questionnaire. Discriminant validity was assessed by comparing the change in Decision Conflict Scale score in women who had failed 2 or less versus 3 or more prior treatments. ResultsFifteen women participated in cognitive interviews. Thematic analysis revealed that women want information about adverse events, personalization of treatment options, and supplemental interactive sources. Sixty-five women participated in the validation study. Decision Conflict Scale scores improved significantly after use of the decision aid (60.2 +/- 22.3 vs 18.7 +/- 19.5, P < 0.001). Change in Decision Conflict Scale score correlated moderately with Patient Satisfaction Questionnaire score (r = 0.437, P = 0.003). Women with 3 or more prior treatment failures had greater improvement in Decision Conflict Scale score than women with 2 or less prior treatment failures (P < 0.001). ConclusionsThe mPDA is a valuable adjunct to physician counseling for treatment options in women with OAB.
