Continence Index: a new screening questionnaire to predict the probability of future incontinence in older women in the community

Nomogram Analysis Based on Clinical and Sonographic Characteristics for the Assessment of Postpartum Stress Urinary Incontinence

OBJECTIVES

We aimed to develop and validate a nomogram integrating clinical and sonographic characteristics for the individualized SUI risk evaluation in the early postpartum stage.

METHODS

This was a prospective cross-sectional study. From June 2020 to September 2022, singleton primiparas who underwent TPUS examination at 6-8 weeks postpartum were recruited. They were divided into the training and validation cohorts at a ratio of 8:2 according to the temporal split. All subjects were interviewed before TPUS examination. Univariate and multivariate logistic analyses were performed to develop three models: the clinical, sonographic, and combined models. The ROC curve was plotted to evaluate model discrimination ability. Finally, the combined model was selected to establish the nomogram. The nomogram's discrimination, calibration, and clinical usefulness were evaluated in the training and validation cohorts.

RESULTS

The performance of the combined model was better than that of the clinical and sonographic models. Six predictors (BMI, delivery mode, lateral episiotomy, SUI during pregnancy, cystocele, and bladder neck funneling) remained in the combined model. The nomogram based on the combined model had good discrimination with AUCs of 0.848 (95% CI: 0.796-0.900) and 0.872 (95% CI: 0.789-0.955) in the training and validation cohorts, respectively, and the calibration curve showed good efficiency in assessing postpartum SUI. Decision curve analysis showed that the nomogram was clinically useful.

CONCLUSIONS

The nomogram based on clinical and sonographic characteristics showed good efficiency in assessing postpartum SUI risk and can be a convenient and reliable tool for individual SUI risk assessment.

Review of the 6th International Consultation on Incontinence: Primary prevention of urinary incontinence

AIMS

To report the state of the science on primary prevention of urinary incontinence (UI) in adults from the 6th International Consultation on Incontinence with an update through January 2019.

METHODS

Online databases PubMed, CINAHL, PsycInfo, and Medline were searched in March 2016 and February 2019 with a focus on literature published after 2010. The International Consultation on Urological Diseases modified Oxford Centre for Evidence-Based Medicine Levels of Evidence and grades of recommendation were used to evaluate the literature.

RESULTS

Grade B recommendations to prevent UI in pregnant and postpartum women are available and promising evidence exists for educational interventions to prevent UI up to 2 years in older women. There is little evidence for adding preoperative pelvic floor muscle exercises to postprostatectomy pelvic floor muscle exercises for men to regain continence. Insufficient evidence exists for the effectiveness of screening for UI in women. The absence of information on primary prevention remains for adolescents, nulliparous and perimenopausal women, and middle-aged and aged men and women.

CONCLUSIONS

Few primary prevention interventions for UI exist for specific populations, especially pregnant and postpartum women. Research interest in developing foundational knowledge to design these interventions is growing.

Effect of Group-Administered Behavioral Treatment on Urinary Incontinence in Older Women: A Randomized Clinical Trial

IMPORTANCE

Urinary incontinence (UI) guidelines recommend behavioral interventions as first-line treatment using individualized approaches. A one-time, group-administered behavioral treatment (GBT) could enhance access to behavioral treatment.

OBJECTIVE

To compare the effectiveness, cost, and cost-effectiveness of GBT with no treatment for UI in older women.

DESIGN, SETTING, AND PARTICIPANTS

Multisite randomized clinical trial (the Group Learning Achieves Decreased Incidents of Lower Urinary Symptoms [GLADIOLUS] study), conducted from July 7, 2014, to December 31, 2016. The setting was outpatient practices at 3 academic medical centers. Community-dwelling women 55 years or older with UI were recruited by mail and screened for eligibility, including a score of 3 or higher on the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), symptoms of at least 3 months' duration, and absence of medical conditions or treatments that could affect continence status. Of 2171 mail respondents, 1125 were invited for clinical screening; 463 were eligible and randomized; 398 completed the 12-month study.

INTERVENTIONS

The GBT group received a one-time 2-hour bladder health class, supported by written materials and an audio CD.

MAIN OUTCOMES AND MEASURES

Outcomes were measured at in-person visits (at 3 and 12 months) and by mail or telephone (at 6 and 9 months). The primary outcome was the change in the ICIQ-SF score. Secondary outcome measures assessed UI severity, quality of life, perceptions of improvement, pelvic floor muscle strength, and costs. Evaluators were masked to group assignment.

RESULTS

Participants (232 in the GBT group and 231 in the control group) were aged 55 to 91 years (mean [SD] age, 64 [7] years), and 46.2% (214 of 463) were African American. In intent-to-treat analyses, the ICIQ-SF scores for GBT were consistently lower than control across all time points but did not achieve the projected 3-point difference. At 3 months, the difference in differences was 0.96 points (95% CI, -1.51 to -0.41 points), which was statistically significant but clinically modest. The mean (SE) treatment effects at 6, 9, and 12 months were 1.36 (0.32), 2.13 (0.33), and 1.77 (0.31), respectively. Significant group differences were found at all time points in favor of GBT on all secondary outcomes except pelvic floor muscle strength. The incremental cost to achieve a treatment success was $723 at 3 months; GBT dominated at 12 months.

CONCLUSIONS AND RELEVANCE

The GLADIOLUS study shows that a novel one-time GBT program is modestly effective and cost-effective for reducing UI frequency, severity, and bother and improving quality of life. Group-administered behavioral treatment is a promising first-line approach to enhancing access to noninvasive behavioral treatment for older women with UI.

Predicting urinary incontinence in women in later life: A systematic review

Urinary incontinence (UI) affects 10-40% of the population and treatment costs in the UK are estimated to be £233 million per annum. A systematic review of online medical databases between July 1974 and 2016 was conducted to identify studies that had investigated risk and prediction strategies of UI in later life. Eighteen prospective longitudinal studies fulfilled the search criteria. These were analysed systematically (as per the PRISMA checklist) and bias risk through study design was minimised where possible upon data analysis. One paper proposed a predictive assessment tool called the 'continence index'. It was derived following secondary analysis of a cohort study and its predictive threshold had suboptimal sensitivity (79%) and specificity (65%) rates. Seventeen studies identified multiple strong risk factors for UI but despite a large selection of papers on the topic, no robust risk assessment tool prospectively identified patients at risk of UI in later life. Thus more research in this field is required. Clinicians should be aware particularly of modifiable UI risk factors to help reduce the clinical burden of UI in the long term.

Effect of Age, Educational Status, Parity and BMI on Development of Urinary Incontinence - a Cross Sectional Study in Saudi Population

BACKGROUND

The research article looks at the background of women with urinary incontinence and exposed to different demographic factors. Women who had urinary incontinence and women without urinary incontinence were compared with regards to their demographic features and risk of development of urinary problems. These risk factors can either cause short term or temporary urinary incontinence or they can cause long term or permanent urinary incontinence. This article explores the association of age, educational status, body mass index (BMI) and parity on the development of urinary incontinence.

AIM OF STUDY

This study aimed at conducting an analysis into the risk factors that are related to urinary incontinence.

RESULTS AND ANALYSIS

Z-tests were conducted for every demographic factor and the results are then discussed comprehensively citing various studies that have been conducted before. Analysis shows that age and BMI increase chances of urinary infection and consequently urinary incontinence. Women of lower educational levels record more cases of urinary incontinence due to lack of general information about the condition. Women with higher parity levels also record more cases of urinary infections and subsequently urinary incontinence.

CONCLUSION

From the analysis above, it can be seen that these factors usually play great roles in the existence and absence of urinary incontinence especially in women in Saudi Arabia. Most important is that, its prevention is mostly by use of the risk factors mentioned here in the research. This will usually involve observing a given risk factor to a state that makes it unfavorable for urinary incontinence to occur.
