Comparative Effectiveness of Initial OAB Treatment Options Among Older Women at High Risk of Falls
Study Details
Study Description
Brief Summary
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 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
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.

Outcome Measures
Primary Outcome Measures
- Evaluability [Assessed at the end of the 12-week intervention period]
Number of participants completing the baseline and the post-intervention assessments divided by number enrolled.
- Clinical-Based Adherence [Assessed at the end of the 12-week intervention period]
Pelvic floor muscle training arm: clinic-based adherence over the 12-week intervention will be calculated by dividing the number of sessions attended by the number of scheduled sessions.
- Home-Based Adherence [Assessed at the end of the 12-week intervention period]
Home-based adherence will be percentage of adherence to the prescribed home program. Patients complete a home exercise diary each time they perform prescribed exercises. The diaries are taken to every clinic appointment and reviewed by the provider.
- Medication Adherence [Assessed at the end of the 12-week intervention period]
Medication arms adherence will be calculated as pill counts, i.e., number of pills dispensed minus the number of pills returned.
Secondary Outcome Measures
- International Consultation on Incontinence Modular Questionnaire - Overactive Bladder (ICIQ-OAB) [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
The ICIQ-OAB is a patient reported outcome that captures self-perceived degree of urinary frequency, urinary urgency (rushing to the bathroom), and urge incontinence (leakage) as well as symptoms related to nocturia (nighttime urination). The overall score is 0-16 with greater values indicating increased symptom severity.
- International Consultation on Incontinence Questionnaire Lower Urinary Tract Symptoms Quality of Life (ICIQ-LUTSqol) [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
The ICIQ-LUTSqol measures the influence of urinary incontinence problems on the quality of life, and changes in interpersonal relations in everyday life. The overall score of ICIQ-LUTSqol is 19-76 score with greater values indicating increased impact on quality of life.
- Falls Efficacy Scale International (FES-I) [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
The Falls Efficacy Scale International (FES-I) is a patient reported outcome that measures level of concern about falling during daily activities inside and outside the home whether or not she actually does the activity. FES-I score ranges from minimum 16 (no concern about falling) to maximum 64 (severe concern about falling).
- Number of Participants with Incident falls [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
An event which results in a person coming to rest inadvertently on the ground or floor or other lower level.
- PROMIS Satisfaction with Participation in Social Roles [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
PROMIS self-reported questionnaire that measures the general satisfaction with performing one's usual social roles and activities. For the adult 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. A higher score equals higher physical functioning.
- Short Physical Performance Battery (SPPB) [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
A battery of 3 physical performance tests: 1) the ability to stand with the feet together in side-by-side, semi-tandem, and tandem positions; 2) time to walk 3 meters; and 3) time to rise from a chair 5 times. A rank ordinal score is given for each test, then all 3 are summed. SPPB total scores range from 0 (worst performance) to 12 (best performance).
- Physical activity [The accelerometer will be worn for 1 week after randomization; for 1 week at the end of the 12-week intervention; and for 1 week at the 6-month follow-up.]
Physical activity monitoring via accelerometry will be used to assess sedentary and physical activity behaviors by calculating total number of steps taken per complete 24 hour day (i.e., midnight-to-midnight) during each monitoring period.
- PROMIS physical functioning 8b [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
PROMIS physical function questionnaire assesses self-reported capability rather than actual performance. This includes functioning of upper & lower extremities, mobility, as well as instrumental activities of daily living, such as running errands. For the adult 8-item form, the lowest possible raw score is 8; the highest possible raw score is 40. A higher score equals higher physical functioning.
- Absorbent pad use [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
Self-reported daily number of absorbent pad used in the previous week. Higher numbers of self reported daily pad use is considered worse than low numbers of daily pad use.
Other Outcome Measures
- Qualitative interviews [Baseline; at the end of the 12-week intervention; and at the 6-month follow-up.]
Semi-structured interview information will be combined with quantitative trial results to: Explore participants lived experiences with these conditions; perceived benefits and harms of the interventions; and examine factors associated with treatment benefits and harms.
