Validation of Instruments for Pragmatic Clinical Trials for Overactive Bladder

Specific Aim 1: To determine the validity and responsiveness of pragmatic patient reported outcome instruments to measure clinical effectiveness, adherence and utility preference scores in adults undergoing treatment with anti-cholinergic medications for overactive bladder. We will perform a prospective cohort study of adults with OAB undergoing treatment with anti-cholinergic medication. We will compare improvement in urinary symptoms (clinical effectiveness), adherence, and change in utility preference scores from baseline to 3 months of treatment using new and existing 'gold standard' instruments. The results will be informative as to which, if any of these pragmatic instruments, is useful for measuring effectiveness, adherence, and utility preference scores in the 'real world' clinical setting. Specific Aim 2: To use the newly validated pragmatic instruments to measure the impact of adherence on clinical effectiveness and health related quality of life in a real world clinical setting in adults undergoing treatment with anti-cholinergic medications for overactive bladder. The impact of adherence on clinical effectiveness and health related quality of life will be measured through comparisons in adults with high and low adherence to anti-cholinergic medication. This aim will corroborate the findings of aim 1 and establish if pragmatic instruments are useful in measuring outcomes of effectiveness, adherence and utility preference scores. These results will also provide preliminary data on the effectiveness of anti-cholinergic medication and the impact of adherence on clinical effectiveness and quality of life in the clinical setting.
