Behavior Enhances Drug Reduction of Incontinence (BE-DRI)
Study Details
Study Description
Brief Summary
The primary aim of this study is to test if the addition of behavioral treatment to drug therapy for the treatment of urge incontinence will increase the number of patients who can discontinue drug therapy and sustain a significant reduction of incontinence.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Combination therapy Women randomly assigned to this condition receive 10 weeks of anti-cholinergic medication (tolterodine) and behavioral training. |
Drug: Tolterodine
4mg/d for 10 weeks. Could be reduced to 2mg/d for managing side effects.
Behavioral: Behavioral training
Training in pelvic floor muscle control and exercises; behavioral strategies to diminish urgency, suppress bladder contractions and prevent incontinence; delayed voiding; and individualized fluid management.
|
Active Comparator: Drug therapy alone Women assigned to this arm received 10 weeks of anti-cholinergic medication (tolterodine), only. |
Drug: Tolterodine
4mg/d for 10 weeks. Could be reduced to 2mg/d for managing side effects.

Outcome Measures
Primary Outcome Measures
- Proportion of Women Who Meet Definition of Success [8 months]
Proportion of women who meet definition of success: not taking drug or receiving other urge UI therapy (i.e., neuromodulation, botox injections, myomectomy, electrical stimulation, or any intravesical therapy) and not taking a tricyclic antidepressant or duloxetine at 8 months; and a >70% reduction in number of incontinence episodes as compared to baseline.
Secondary Outcome Measures
- Change in Incontinence Episodes [Baseline and 10 weeks]
Change from baseline to 10 weeks in number of incontinence episodes per week as reported on bladder diary.
- Change in Voids Per Day [baseline and 10 weeks]
Change from baseline to 10 weeks in frequency of voids per day as reported on bladder diary
- Symptom Distress [baseline, 10 weeks and 8 months]
Urogenital distress inventory (UDI). Higher score indicates greater distress. Possible range 0 to 300.
- Symptom Bother [baseline, 10 weeks and 8 months]
Disease specific overactive bladder scale (OAB-q). HIgher score indicates greater bother. Possible range 0 to 100.
- Satisfaction [10 weeks]
Number of women who responded "completely satisfied" to question, "How satisfied are you with your progress?"
- Satisfaction [8 months]
Number of women who responded "completely satisfied" to question "How satisfied are you with your progress?"
- Symptom Improvement [10 weeks]
Number of women who responded "much better" or "better" to question: "Overall, do you feel that you are much better, better, about the same, worse or much worse?"
- Symptom Improvement [8 months]
Number of women who responded "much better" or "better" to question: "Overall, do you feel that you are much better, better, about the same, worse or much worse?"

Study Results
Participant Flow
Recruitment Details | Between July, 2004 and January, 2006 4,043 women were screened for eligibility and 561 provided written consent. After further screening, 134 were found to be ineligible, 119 withdrew consent and 1 was excluded erroneously. The remaining 307 were randomized to one of the treatment arms. |
---|---|
Pre-assignment Detail | Of the 134 found to be ineligible after consent, for 77 their urinary incontinence (UI) was not urge predominant, 19 had fewer than 7 episodes of incontinence per week and the other 38 were excluded for a variety of reasons. |
