OBJECTIVE: The purpose of this study was to examine the effects of combinin
g behavioral treatment and drug treatment for urge incontinence in communit
y-dwelling older women.
DESIGN: Modified crossover design (extension of a randomized clinical trial
). Eligible subjects were stratified according to type and severity of inco
ntinence and randomized to behavioral treatment, drug treatment, or a contr
ol condition (placebo). Subjects not totally continent or not satisfied aft
er 8 weeks of a single treatment were offered the opportunity to cross over
into combined therapy.
SETTING: A university-based outpatient geriatric medicine clinic.
PARTICIPANTS: Subjects in the clinical trial were 197 ambulatory, nondement
ed, community-dwelling women (age 55 years or older) with persistent urge u
rinary incontinence. Thirty-five subjects participated in combined treatmen
t.
INTERVENTION: One group of subjects received four sessions (over 8 weeks) o
f biofeedback-assisted behavioral training followed by 8 weeks of behaviora
l training combined with drug therapy (oxpbutynin chloride individually tit
rated from 2.5 mg to 15 mg daily). The second group received drug therapy f
irst, followed by 8 weeks of drug therapy combined with behavioral training
.
MEASUREMENTS: Bladder diaries completed by subjects before and after each t
reatment phase were used to calculate change in the frequency of incontinen
t episodes.
RESULTS: Eight subjects (12.7%) crossed from behavioral treatment alone to
combined behavioral and drug therapy. Additional benefit was seen in improv
ement from a mean 57.5% reduction of incontinence with single therapy to a
mean 88.5% reduction of incontinence with combined therapy (P = .034). Twen
ty-seven subjects (41.5%) crossed from drug therapy alone to combined drug
and behavioral treatment. They also showed additional improvement, from a m
ean 72.7% reduction of incontinence with single therapy to a mean 84.3% red
uction of incontinence with combined therapy (P = .001).
CONCLUSIONS: This study shows that combining drug and behavioral therapy in
a stepped program can produce added benefit for patients with urge inconti
nence.
