Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to conduct a randomized pilot multi-arm clinical trial comparing a standard course of physical therapist provided pelvic floor muscle training (PFMT) to pharmacologic therapy for the treatment of urgency urinary incontinence (UUI) or Overactive Bladder (OAB) in older women at high risk of falling.

The central hypotheses for this project are i) a randomized pilot multi-arm clinical trial comparing PFMT to drug treatment for UUI or OAB in older women at high risk of falling is feasible; and ii) treatment approach can influence both UI and fall related outcomes in this patient population.

The main questions it aims to answer are: 1) Is a multi-arm clinical trial comparing PFMT to drug treatment for UUI or OAB in older women at high risk of falling feasible? and 2) How does treatment approach influence both OAB and fall related outcomes in this patient population?

Women (16 per arm) 60 years and older with UUI or OAB who screen positive for high fall risk will be randomized to one of three standard of care treatment arms and followed for six months. The three treatment arms are i) a 12-week structured behaviorally based pelvic floor muscle training (PFMT) intervention administered by physical therapists in the outpatient physical therapy clinic; ii) a 12-week course of the beta-3 agonist, Mirabegron; and iii) a 12-week course of the antimuscarinic, Trospium Chloride. Researchers will compare study feasibility and OAB symptom related outcomes across the three groups to see if a larger clinical trial is warranted.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Untreated, urinary urgency and incontinence can precipitate a vicious cycle of decreasing physical activity, social isolation, fear-of-falling, and falls. The urge to urinate frequently can also limit physical activity - concern for finding oneself too far from a bathroom can be a powerful motivator for just staying home. Structured behavioral interventions or medications are common initial treatment options. But they elicit their effects through very different mechanisms of action that may influence fall related outcomes differently. There is, however, a critical lack of direct head-to-head trial evidence on non-pharmacologic and pharmacologic treatments for urgency urinary incontinence (UUI), particularly in women with co-existing fall risk. The proposed feasibility pilot study is a randomized, multi-arm, mixed methods, clinical trial comparing three currently in use initial treatment options for older women: i) a 12-week structured behaviorally based pelvic floor muscle training (PFMT) intervention administered by physical therapists in the clinic; ii) a 12-week course of the beta-3 agonist, Mirabegron; and iii) a 12-week course of the antimuscarinic, Trospium Chloride, in women 60 and older with UUI or overactive bladder (OAB) who also screen positive for increased risk of falling. Mirabegron and Trospium are not associated with longitudinal effects on cognition that the traditionally used anticholinergic mediations have recently been linked to. The Specific Aims are 1) Conduct a pilot study in clinical settings to determine the feasibility of enrolling older women with UUI or OAB who are at high risk of falling in a three-arm (PFMT, vs. mirabegron vs. Trospium), randomized comparative effectiveness trial; 2) Characterize outcomes across the three interventions; and 3) Qualitatively explore perceived factors influencing the non-pharmacologic and pharmacologic treatment experience in these patients. Forty-eight ambulatory women (16 per arm) 60 years and older with UUI or OAB and who screen positive for high fall risk will be randomized (1:1:1) to one of three arms. Feasibility will be determined through key milestones on evaluability, adherence to the interventions, attrition, adverse events, productive recruitment methods, and sample characteristics. The Investigators will also measure important indicators of symptom severity, quality of life, physical activity, falls, and fear of falling. Building upon our preliminary work, fall risk will be determined by the Centers for Disease Control and Prevention (CDC), Stopping Elderly Accidents, Deaths, and Injuries (STEADI) fall risk screening tool. The proposed study is the first to compare these common non-surgical treatments for UUI and OAB in a high fall risk patient population and will lay the groundwork for a program of research investigating the bidirectional relationships that exist across these two common geriatric syndromes both at the level of shared risk factors and response to treatment.
