Isolated Urinary, Fecal, and Double Incontinence: Prevalence and Degree of Soiling in Stroke Survivors

Global Prevalence of Fecal Incontinence in Community-Dwelling Adults: A Systematic Review and Meta-analysis

BACKGROUND & AIMS

Fecal incontinence (FI) can considerably impair quality of life. Through a systematic review and meta-analysis, we sought to determine the global prevalence and geographic distribution of FI and to characterize its relationship with sex and age.

METHODS

We searched PubMed, Web of Science, and Cochrane Library databases to identify population-based surveys of the prevalence of FI.

RESULTS

Of the 5175 articles identified, the final analysis included 80 studies; the median response rate was 66% (interquartile range [IQR], 54%-74%). Among 548,316 individuals, the pooled global prevalence of FI was 8.0% (95% confidence interval [CI], 6.8%-9.2%); by Rome criteria, it was 5.4% (95% CI, 3.1%-7.7%). FI prevalence was greater for persons aged 60 years and older (9.3%; 95% CI, 6.6%-12.0%) compared with younger persons (4.9%; 95% CI, 2.9%-6.9%) (odds ratio [OR], 1.75; 95% CI, 1.39-2.20), and it was more prevalent among women (9.1%; 95% CI, 7.6%-10.6%) than men (7.4%; 95% CI, 6.0%-8.8%]) (OR, 1.17; 95% CI, 1.06-1.28). The prevalence was highest in Australia and Oceania, followed by North America, Asia, and Europe, but prevalence could not be estimated in Africa and the Middle East. The risk of bias was low, moderate, and high for 19 (24%), 46 (57%), and 15 (19%) studies, respectively. Exclusion of studies with high risk of bias did not affect the prevalence of FI or heterogeneity. In the meta-regression, the high study heterogeneity (I2 = 99.61%) was partly explained by age.

CONCLUSIONS

Approximately 1 in 12 adults worldwide have FI. The prevalence is greater among women and older people.

Evaluating methods of detecting and determining the type of urinary incontinence in adults after stroke: A systematic review

INTRODUCTION

Urinary incontinence (UI) affects over half of people with stroke. It is unclear which methods are accurate in assessing presence and type of UI to inform clinical management. Diagnosis of UI based on inaccurate methods may lead to unnecessary interventions. The aims of this systematic review were to identify, for adults with stroke, clinically accurate methods to determine the presence of UI and type of UI.

METHOD

We searched seven electronic databases and additional conference proceedings. To be included, studies had to be primary research comparing two or more methods, or use a reference test.

RESULTS

We identified 3846 studies with eight eligible for inclusion. We identified 11 assessment methods within the eight studies. Only five studies had sufficient comparator data for synthesis. Due to heterogeneity of data, results on the following methods were narratively synthesized: Core Lower Urinary Tract Symptom Score (CLSS), clinical history and physical examination, Barthel Activities of Daily Living Index, International Consultation Incontinence Questionnaire Short Form (ICiQ-SF) and urodynamic studies (UDS). Most studies were small and of low to medium quality. All reported differences in sensitivity, and none compared the same assessment methods.

CONCLUSION

Current evidence is insufficient to support recommendations on the most accurate UI assessment for adults with stroke. Further research is needed.

Gastrointestinal Dysfunction in Stroke

Gastrointestinal (GI) complications are seen in over 50% of ischemic stroke survivors; the most common complications are dysphagia, constipation, and GI bleeding. The bidirectional relationship of the gut-brain axis and stroke has recently gained traction, wherein stroke contributes to gut dysbiosis (alterations in the normal host intestinal microbiome) and gut dysbiosis perpetuates poor functional neurologic outcomes in stroke. It is postulated that the propagation of proinflammatory cells and gut metabolites (including trimethylamine N-oxide and short-chain fatty acids) from the GI tract to the central nervous system play a central role in gut-brain axis dysfunction. In this review, we discuss the known GI complications in acute ischemic stroke, our current knowledge from experimental stroke models for gut-brain axis dysfunction in stroke, and emerging therapeutics that target the gut-brain axis.

Faecal incontinence in adults

Faecal incontinence, which is defined by the unintentional loss of solid or liquid stool, has a worldwide prevalence of ≤7% in community-dwelling adults and can markedly impair quality of life. Nonetheless, many patients might not volunteer the symptom owing to embarrassment. Bowel disturbances, particularly diarrhoea, anal sphincter trauma (obstetrical injury or previous surgery), rectal urgency and burden of chronic illness are the main risk factors for faecal incontinence; others include neurological disorders, inflammatory bowel disease and pelvic floor anatomical disturbances. Faecal incontinence is classified by its type (urge, passive or combined), aetiology (anorectal disturbance, bowel symptoms or both) and severity, which is derived from the frequency, volume, consistency and nature (urge or passive) of stool leakage. Guided by the clinical features, diagnostic tests and therapies are implemented stepwise. When simple measures (for example, bowel modifiers such as fibre supplements, laxatives and anti-diarrhoeal agents) fail, anorectal manometry and other tests (endoanal imaging, defecography, rectal compliance and sensation, and anal neurophysiological tests) are performed as necessary. Non-surgical options (diet and lifestyle modification, behavioural measures, including biofeedback therapy, pharmacotherapy for constipation or diarrhoea, and anal or vaginal barrier devices) are often effective, especially in patients with mild faecal incontinence. Thereafter, perianal bulking agents, sacral neuromodulation and other surgeries may be considered when necessary.

Current Incidence and Risk Factors of Fecal Incontinence After Acute Stroke Affecting Functionally Independent People

Background: Previously published retrospective series show a high prevalence of fecal incontinence (FI) in stroke patients. We aimed to analyze in a prospective series the current incidence of FI in acute stroke in functionally independent patients and its evolution over time and the patient characteristics associated with the appearance of FI in acute stroke. Methods: We included consecutive patients with acute stroke admitted in our stroke unit who fulfilled the following inclusion criteria: a first episode of stroke, aged >18 years, with no previous functional dependency [modified Rankin Scale (mRS) ≤ 2] and without previous known FI. FI was assessed by a multidisciplinary trained team using dedicated questionnaires at 72 ± 24 h (acute phase) and at 90 ± 15 days (chronic phase). Demographic, medical history, clinical and stroke features, mortality, and mRS at 7 days were collected. Results: Three hundred fifty-nine (48.3%) of 749 patients (mean age 65.9 ± 10, 64% male, 84.1% ischemic) fulfilled the inclusion criteria and were prospectively included during a 20-month period. FI was identified in 23 patients (6.4%) at 72 ± 24 h and in 7 (1.9%) at 90 days ± 15 days after stroke onset. FI was more frequent in hemorrhagic strokes (18 vs. 5%, p 0.007) and in more severe strokes [median National Institute of Health Stroke Scale (NIHSS) 18 (14-22) vs. 5 (3-13), p < 0.0001]. No differences were found regarding age, sex, vascular risk factors, or other comorbidities, or affected hemisphere. Patients with NIHSS ≥12 (AUC 0.81, 95% CI 0.71 to 0.89) had a 17-fold increase for the risk of FI (OR 16.9, IC 95% 4.7-60.1) adjusted for covariates. Conclusions: At present, the incidence of FI in acute stroke patients without previous functional dependency is lower than expected, with an association of a more severe and hemorrhagic stroke. Due to its impact on the quality of life, it is necessary to deepen the knowledge of the underlying mechanisms to address therapeutic strategies.

Urinary symptoms in women with faecal incontinence

AIM

Faecal incontinence (FI) is estimated to affect 8.9% of women in the United States, with a significant impact on quality of life. Our aim was to compare urinary symptoms in patients with and without FI with different degrees of severity.

METHODS

This prospective cohort of women presented for care at a pelvic floor disorder centre between May 2007 and January 2019. We excluded women with a history of bowel resection, prior history of pelvic organ prolapse surgery or existing prolapse symptoms reported by the patient during intake. The primary outcome was the presence of urinary symptoms in women with and without FI by validated questionnaires. A logistic regression model for association of urinary symptoms with FI was performed, adjusting for age, smoking, diabetes, prior hysterectomy and irritable bowel syndrome.

RESULTS

A total of 2932 met inclusion criteria, and of these 1404 (47.89%) reported FI. In the univariate analysis, patients with FI were more likely to have urgency urinary incontinence (P = 0.01) or mixed urinary incontinence (P < 0.001), report nocturnal enuresis (P < 0.001) or have leakage of urine during sex (P < 0.001). In an adjusted model, FI was associated with concurrent stress (adjusted OR 1.28, P = 0.034), urgency (adjusted OR 1.52, P < 0.001) and mixed incontinence (adjusted OR 1.94, P < 0.001).

CONCLUSION

In women with pelvic floor disorders, the presence of FI is associated with a higher prevalence of urinary incontinence. Pelvic floor specialists should assess urinary incontinence symptoms along with the presence and severity of FI to provide comprehensive care and guide appropriate therapy.

Urinary and fecal incontinence in stroke survivors followed in general practice: A retrospective cohort study

BACKGROUND

Investigating the short- and long-term health outcomes after stroke is a public health priority.

OBJECTIVES

We aimed to analyse the incidence of urinary and fecal incontinence within 10 years of stroke in individuals followed in general practice in Germany.

METHODS

Individuals who had received an initial stroke diagnosis at one of 1262 general practices in Germany between January 2006 and December 2015 were included (index date). Individuals without stroke were matched (1:1) to those with stroke based on propensity scores by using a "greedy" algorithm and logistic regression with sex, age, index year, and 17 comorbidities diagnosed in the 12 months before the index date. The main outcome of the study was the incidence of urinary and fecal incontinence within 10 years of stroke.

RESULTS

This study analysed data for 16,181 individuals with stroke and 16,181 without stroke. Within 10 years of the index date, 22% and 11% of men with and without stroke received a diagnosis of urinary incontinence (log-rank P<0.001); the prevalence of urinary incontinence was 34% in female stroke survivors and 17% in females with no history of stroke (log-rank P<0.001). The respective proportions of fecal incontinence were 5% and 2% for men (log-rank P<0.001) and 6% and 3% for women (log-rank P<0.001). Overall, stroke was positively associated with both urinary incontinence (men: hazard ratio [HR] 2.34, 95% confidence interval [CI] 2.10-2.61; women: HR 2.36, 95% CI 2.14-2.61) and fecal incontinence (men: HR 2.43, 95% CI 1.88-3.13; women: HR 2.60, 95% CI 1.98-3.41).

CONCLUSION

This study, using data from Germany, suggests that general practitioners should regularly screen for urinary and fecal incontinence in the decade following stroke.

The Prevalence, Incidence, and Correlates of Fecal Incontinence Among Older People Residing in Care Homes: A Systematic Review

OBJECTIVE

Older people resident in care homes often rely on staff for support relating to their activities of daily living, including intimate care such as continence care. Managing fecal incontinence can be challenging for both residents and care staff. We conducted this review to describe the prevalence, incidence, and correlates of fecal incontinence among care home residents.

DESIGN

Systematic literature review.

SETTING AND PARTICIPANTS

Older care home residents (both nursing and residential care) aged 60 years and older.

MEASURES

We defined double incontinence as the presence of fecal plus urinary incontinence, isolated fecal incontinence as fecal incontinence with no urinary incontinence, and all fecal incontinence as anyone with fecal incontinence (whether isolated or double). The CINAHL and MEDLINE databases were searched up to December 31, 2017, to retrieve all studies reporting the prevalence and/or incidence and correlates of fecal incontinence.

RESULTS

We identified 278 citations after removing duplicates, and 23 articles met the inclusion criteria. There were 12 high-quality studies, 5 medium-quality studies, and 6 low-quality studies. The medians for prevalence (as reported by the studies) of isolated fecal incontinence, double incontinence, and all fecal incontinence were 3.5% [interquartile range (IQR) = 2.8%], 47.1% (IQR = 32.1%), and 42.8% (IQR = 21.1%), respectively. The most frequently reported correlates of fecal incontinence were cognitive impairment, limited functional capacity, urinary incontinence, reduced mobility, advanced age, and diarrhea.

CONCLUSIONS/IMPLICATIONS

Fecal incontinence is prevalent among older people living in care homes. Correlates included impaired ability to undertake activities of daily living, reduced mobility, laxative use, and altered stool consistency (eg, constipation or diarrhea) which are potentially amenable to interventions to improve fecal incontinence.

Systematic review of the prevalence of faecal incontinence

BACKGROUND

Faecal incontinence (FI) is widely recognized as a significant problem in the community. Conjecture exists around the proportion of the population affected. This systematic review evaluated studies reporting the community prevalence of FI in terms of methodology, design and definitions.

METHODS

MEDLINE, Embase, CINAHL, the Cochrane Collaboration and National Guideline databases were searched for studies investigating the prevalence of FI in community-based adults published from January 1966 to February 2015. Study data, including methodology, sample size, response rate, definition of FI and prevalence rates, were extracted on to a pro forma and appraised critically. Where possible, FI prevalence estimates were pooled.

RESULTS

Thirty studies were analysed from 4840 screened articles. FI prevalence estimates varied from 1·4 to 19·5 per cent. This variation was explained by differences in data collection method and two factors within definitions of FI: type of stool and frequency of FI episodes. When these factors were accounted for, the FI prevalence at a threshold of at least once per month for liquid or solid stool was 8·3-8·4 per cent for face-to-face or telephone interviews, and 11·2-12·4 per cent for postal surveys. The pooled prevalence rate from studies for functional FI (defined by ROME II criteria) was 5·9 (95 per cent c.i. 5·6 to 6·3) per cent.

CONCLUSION

When comparable methodologies and definitions are used, studies produce remarkably similar prevalence rates in different community populations. FI remains an unspoken symptom, with lower rates reported in personal interviews compared with anonymous postal questionnaires.

Gastrointestinal complications after ischemic stroke

Ischemic stroke is an important cause of morbidity and mortality, and currently the leading cause of adult disability in developed countries. Stroke is associated with various non-neurological medical complications, including infections and thrombosis. Gastrointestinal complications after stroke are also common, with over half of all stroke patients presenting with dysphagia, constipation, fecal incontinence or gastrointestinal bleeding. These complications are associated with increased hospital length of stay, the development of further complications and even increased mortality. In this article we review the epidemiology, pathophysiology, diagnosis, management and prevention of the most common gastrointestinal complications associated with ischemic stroke.

Prevalence of anal incontinence among Norwegian women: a cross-sectional study

OBJECTIVE

Anal incontinence (AI) is a symptom associated with age, bowel symptoms and obstetric injuries. Primary aim of the study was to establish the prevalence of AI among women and secondarily to evaluate the impact on daily life and conditions associated with AI.

DESIGN

A cross-sectional study.

SETTING

Participants attended research stations located in different parts of Nord-Trøndelag county, Norway. Data were collected through interviews, questionnaires and clinical examinations.

PARTICIPANTS

In total, 40 955 community-dwelling women aged 30 years and older were invited. A total of 25 037 women participated, giving a participation rate of 61.1%.

PRIMARY AND SECONDARY OUTCOME MEASURES

Fecal incontinence and flatal incontinence was defined as involuntary loss of feces and flatus weekly or more, respectively. AI was defined as the involuntary loss of feces and/or flatus weekly or more. Urgency was defined as the inability to defer defecation for 15 min. Statistical methods included prevalence estimates and logistic regression analysis.

RESULTS

Questions about AI were completed by 20 391 (82.4%) women. Among the 20 391 women, AI was reported by 19.1% (95% CI 18.6% to 19.7%) and fecal incontinence was reported by 3.0% (95% CI 2.8% to 3.2%). Urgency was experienced by 2586 women (12.7%, 95% CI 12.2 to 13.1). Impact on daily life was stated by 794 (26.0%, 95% CI 24.4 to 27.5) women with AI. In bivariate age-adjusted analysis of AI, OR and CI for urgency (OR 3.19, 95% CI 2.92 to 3.49) and diarrhoea (OR 3.81, 95% CI 3.32 to 4.38) revealed strongest associations with AI.

CONCLUSIONS

AI affects one in five women older than 30 years. Strongest associated symptoms are urgency and diarrhoea.

TRIAL REGISTRATION NUMBER

The study was approved by the Regional Committee for Medical and Health Research Ethics (No. 2009/1214) and followed the Declaration of Helsinki.

Faecal incontinence in older people

Faecal incontinence in older people is a distressing and socially isolating symptom and increases the risk of morbidity, mortality and dependency. Many older individuals with faecal incontinence will not volunteer the problem to their general practitioner or nurse and, regrettably, health care providers do not routinely enquire about the symptom. Even when older people are noted by health care professionals to have faecal incontinence, the condition is often managed passively, especially in the long-term care setting where it is most prevalent. The importance of identifying treatable causes of faecal incontinence in older people, rather than just managing passively, is strongly emphasized in national and international guidance, but audit shows that adherence to such guidance is generally poor. This article describes epidemiology, causes, assessment, diagnosis and treatment of faecal incontinence in older people.

Incontinence: assessment, diagnosis, and management in two rehabilitation units for older people

BACKGROUND

Incontinence of both bladder and bowel is a major health care problem and adversely affects the lives of many people living at home or in health service facilities. The prevalence and severity of incontinence is a global concern that has, in recent years, prompted investigation across several countries. Current approaches to continence care indicate an emphasis on safety and reduction of risk, rather than on detailed individualised assessment and management.

AIM

To show approaches to assessment, diagnosis, and management of urinary and faecal incontinence in two rehabilitation settings for older people in Ireland. The study forms part of a larger 2-year case study to identify the determinants of practice "context" that enable or hinder proactive approaches to promoting continence and the treatment of incontinence in rehabilitation settings for older people.

METHOD

The Royal College of Physicians Audit Scheme was used to record the assessment and management of urinary and faecal incontinence. This scheme also includes questions regarding resources available to enable effective continence management. Over 6 months, 220 patients who suffered from incontinence participated in two study sites: a 78-bed rehabilitation unit in Northern Ireland and an 80-bed rehabilitation unit in Southern Ireland.

RESULTS

Findings indicated that 60% of incontinent patients had urinary incontinence, 3% faecal incontinence, and 37% mixed urinary and faecal incontinence; however, a specific continence assessment and specific rationale for treatment decisions or continuation of care were lacking. The focus was on continence containment rather than on proactive management. The examination of resources available for continence promotion and management showed that even though guidelines for continence management were available to staff in one unit, there was a dearth of appropriate education or support for staff in continence care.

IMPLICATIONS FOR PRACTICE

Because incontinence remains an issue for older people and the clinical implications of sustained incontinence are multifaceted, strategies should focus on the development of practice towards evidence-based multidisciplinary approaches to continence promotion and management.
