ABSTRACT
INTRODUCTION: Many women choose behavioral interventions as first line treatment for urinary incontinence. We developed a 20-minute abbreviated video, which proved to be similar to a 2-hour in-person class in a randomized trial. This study examines economic end points for the 20-minute video relative to the 2-hour class. METHODS: We randomized 332 participants to the 2-hour class and 315 to the 20-minute video. We estimated the cost for the 2-hour class, the 20-minute video and followup health care utilization. Participants were followed for 3, 12 and 24 months, and asked about health care utilization, quality of life and lost productivity. To measure perceived value, we queried each participant regarding willingness to pay. Regression analysis was used for statistical comparisons. RESULTS: The estimated per participant cost for a 2-hour class was $38, which was more than the marginal cost of the video ($0). We found no significant differences between the treatment groups at each followup for quality of life, lost productivity or health care utilization. Women were willing to pay $26, $21 and $30 for a copy of the DVD, video on the Web and in-person class, respectively, all of which were less than the average cost of the in-person class ($38). CONCLUSIONS: Poor adherence remains a challenge for many behavioral interventions designed to prevent urinary incontinence. The 20-minute video is less expensive than the 2-hour class and is equally effective. Distributing the video on the Internet will improve access and will be easier to sustain than in-person classes.
ABSTRACT
PURPOSE: We compared 2-year urinary incontinence and urgency scores of older women who attended a 2-hour bladder health class vs those who viewed a 20-minute abbreviated class video for the purpose of urinary incontinence prevention. MATERIALS AND METHODS: A randomized, 2-arm, parallel design study was done to test the superiority of the 20-minute video over the 2-hour class. Outcomes at baseline, and 3, 12 and 24 months were the scores on questions 1 to 3 of ICIQ-SF (International Consultation on Incontinence Short Form) as the primary outcome and on IUSS (Indevus Urgency Severity Scale). Intent to treat analysis was done to compare the change from baseline in each intervention group across time and also with each other. Multiple imputation was used for missing data. RESULTS: A total of 647 women participated in the study. Mean age was 63 years and approximately 28% of the participants were African American, primarily from an urban setting. The 2 arms were balanced on body mass index at baseline, age, race/ethnicity, education, employment status, income and marital status. No differences in primary or secondary outcomes were demonstrated between the 2 groups from baseline to the 3, 12 or 24-month visits. CONCLUSIONS: The absence of significant differences in the outcome measures of ICIQ-SF and IUSS between the 2-hour class and the 20-minute video groups demonstrates that the 2 interventions were comparable. As urinary incontinence and urgency tend to rise annually in older women, instruction in bladder health self-care provided through either the 2-hour class or the 20-minute video format is a useful intervention to prevent urinary incontinence in older women.
