Factors contributing to fecal incontinence in older people and outcome of routine management in home, hospital and nursing home settings

Constipation and Fecal Incontinence in the Elderly

PURPOSE OF REVIEW

To review the epidemiology, pathogenesis, clinical features, and management of primary constipation and fecal incontinence in the elderly.

RECENT FINDINGS

Among elderly people, 6.5%, 1.7%, and 1.1% have functional constipation, constipation-predominant IBS, and opioid-induced constipation. In elderly people, the number of colonic enteric neurons and smooth muscle functions is preserved; decreased cholinergic function with unopposed nitrergic relaxation may explain colonic motor dysfunction. Less physical activity or dietary fiber intake and postmenopausal hormonal therapy are risk factors for fecal incontinence in elderly people. Two thirds of patients with fecal incontinence respond to biofeedback therapy. Used in combination, loperamide and biofeedback therapy are more effective than placebo, education, and biofeedback therapy. Vaginal or anal insert devices are another option. In the elderly, constipation and fecal incontinence are common and often distressing symptoms that can often be managed by addressing bowel disturbances. Selected diagnostic tests, prescription medications, and, infrequently, surgical options should be considered when necessary.

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.

Managing Faecal INcontinence in people with advanced dementia resident in Care Homes (FINCH) study: a realist synthesis of the evidence

BACKGROUND

Eighty per cent of care home residents in the UK are living with dementia. The prevalence of faecal incontinence (FI) in care homes is estimated to range from 30% to 50%. There is limited evidence of what is effective in the reduction and management of FI in care homes.

OBJECTIVE

To provide a theory-driven explanation of the effectiveness of programmes that aim to improve FI in people with advanced dementia in care homes.

DESIGN

A realist synthesis. This was an iterative approach that involved scoping of the literature and consultation with five stakeholder groups, a systematic search and analysis of published and unpublished evidence, and a validation of programme theories with relevant stakeholders.

DATA SOURCES

The databases searched included PubMed, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, Scopus, SocAbs, Applied Social Sciences Index and Abstracts, BiblioMap, Sirius, OpenGrey, Social Care Online and the National Research Register.

RESULTS

The scoping identified six programme theories with related context-mechanism-outcome configurations for testing. These addressed (1) clinician-led support, assessment and review, (2) the contribution of teaching and support for care home staff on how to reduce and manage FI, (3) the causes and prevention of constipation, (4) how the cognitive and physical capacity of the resident affect outcomes, (5) how the potential for recovery, reduction and management of FI is understood by those involved and (6) how the care of people living with dementia and FI is integral to the work patterns of the care home and its staff. Data extraction was completed on 62 core papers with iterative searches of linked literature. Dementia was a known risk factor for FI, but its affect on the uptake of different interventions and the dementia-specific continence and toileting skills staff required was not addressed. Most care home residents with FI will be doubly incontinent and, therefore, there is limited value in focusing solely on FI or on single causes of FI such as constipation. Clinical assessment, knowledge of the causes of FI and strategies that recognise the individuals' preferences are necessary contextual factors. Valuing the intimate and personal care work that care home staff provide to people living with dementia and addressing the dementia-related challenges when providing continence care within the daily work routines are key to helping to reduce and manage FI in this population.

LIMITATIONS

The synthesis was constrained by limited evidence specific to FI and people with dementia in care homes and by the lack of dementia-specific evidence on continence aids.

CONCLUSIONS

This realist synthesis provides a theory-driven understanding of the conditions under which improvement in care for care home residents living with dementia and FI is likely to be successful.

FUTURE WORK

Future multicomponent interventions need to take account of how the presence of dementia affects the behaviours and choices of those delivering and receiving continence care within a care home environment.

Epidemiology, pathophysiology, and classification of fecal incontinence: state of the science summary for the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) workshop

In August 2013, the National Institutes of Health sponsored a conference to address major gaps in our understanding of the epidemiology, pathophysiology, and management of fecal incontinence (FI) and to identify topics for future clinical research. This article is the first of a two-part summary of those proceedings. FI is a common symptom, with a prevalence that ranges from 7 to 15% in community-dwelling men and women, but it is often underreported, as providers seldom screen for FI and patients do not volunteer the symptom, even though the symptoms can have a devastating impact on the quality of life. Rough estimates suggest that FI is associated with a substantial economic burden, particularly in patients who require surgical therapy. Bowel disturbances, particularly diarrhea, the symptom of rectal urgency, and burden of chronic illness are the strongest independent risk factors for FI in the community. Smoking, obesity, and inappropriate cholecystectomy are emerging, potentially modifiable risk factors. Other risk factors for FI include advanced age, female gender, disease burden (comorbidity count, diabetes), anal sphincter trauma (obstetrical injury, prior surgery), and decreased physical activity. Neurological disorders, inflammatory bowel disease, and pelvic floor anatomical disturbances (rectal prolapse) are also associated with FI. The pathophysiological mechanisms responsible for FI include diarrhea, anal and pelvic floor weakness, reduced rectal compliance, and reduced or increased rectal sensation; many patients have multifaceted anorectal dysfunctions. The type (urge, passive or combined), etiology (anorectal disturbance, bowel symptoms, or both), and severity of FI provide the basis for classifying FI; these domains can be integrated to comprehensively characterize the symptom. Several validated scales for classifying symptom severity and its impact on the quality of life are available. Symptom severity scales should incorporate the frequency, volume, consistency, and nature (urge or passive) of stool leakage. Despite the basic understanding of FI, there are still major knowledge gaps in disease epidemiology and pathogenesis, necessitating future clinical research in FI.

National audit of continence care: adherence to National Institute for Health and Clinical Excellence (NICE) guidance in older versus younger adults with faecal incontinence

BACKGROUND

previous UK National Audits of Continence Care showed low rates of assessment and treatment of faecal incontinence (FI) in older people.

OBJECTIVE

the 2009 audit assessed adherence to the National Institute for Health and Clinical Excellence guidelines on management of FI and compared care in older versus younger patients.

METHODS

fifteen older (65+) and 15 younger (18-65) patients with FI were to be audited in hospital (inpatient or outpatient), primary care (PC) and care home sites.

RESULTS

data were submitted for n = 2,930 cases from 133 hospitals, n = 1,729 from 97 PC surgeries and n = 693 from 63 care homes. Bowel history was not documented in 41% older versus 24% younger patients in hospitals and 27 versus 19% in PC (both P < 0.001). In older people, there was no documented focused examination in one-third in hospitals, one-half in PC and three-quarters in care homes. Overall, <50% had documented treatment for an identified bowel-related cause of FI. FI was frequently attributed to co-morbidity. Few patients received copies of their treatment plan. Quality-of-life impact was poorly documented particularly in hospitals.

CONCLUSIONS

this national audit shows deficits in documented assessment, diagnosis and treatment for adults with FI despite availability of clinical guidance. Overall care is significantly poorer for older people. Clinicians, including geriatricians, need to lead on improving care in older people including comprehensive assessment where needed. Improvement in some indicators in older people with successive audits suggests that ongoing national audit with linked information resources can be useful as both monitor and agent for change.

Anorectal physiology and pathophysiology in the elderly

Anorectal medical disorders facing the elderly include fecal incontinence, fecal impaction with overflow fecal incontinence, chronic constipation, dyssynergic defecation, hemorrhoids, anal fissure, and pelvic floor disorders. This article discusses the latest advances in age-related changes in morphology and function of anal sphincter, changes in cellular and molecular biology, alterations in neurotransmitters and reflexes, and their impact on functional changes of the anorectum in the elderly. These biophysiologic changes have implications for the pathophysiology of anorectal disorders. A clear understanding and working knowledge of the functional anatomy and pathophysiology will enable appropriate diagnosis and treatment of these disorders.

What characteristics predispose to continence in nursing home residents?: a population-based cross-sectional study

Aims

To compare characteristics of both continent and incontinent residents in Nursing Homes (NHs) and to explore what predicts continence and severity of incontinence.

Methods

A population-based cross-sectional study was performed in nursing homes in one Norwegian municipality. Registered nurses filled in a questionnaire on behalf of the patients.

Results

We found that 25.4% of the NH residents were continent, 31.8% had urinary incontinence alone, 2.6% had fecal incontinence alone and 40.2% had double incontinence. Continent residents were characterized by being in short-term care, shorter stay in NH, less cognitive and physical impairment, less Parkinson's disease, stroke, constipation, and less diarrhea and more independence in activities of daily living (ADL). Residents with fecal incontinence alone were characterized by more diarrhea, less cognitive impairment and less dependency in ADL such as feeding and grooming. Residents with urinary incontinence alone were characterized by having some degree of ADL dependency, less diarrhea, and less diabetes. Residents with double incontinence were characterized by being in long-term care, a longer length of stay in NH, cognitive impairment, stroke, constipation, diarrhea, and dependency in ADL. Severity of incontinence was associated with dependency in ADL and cognitive impairment, diarrhea, length of stay in NH and lower age.

Conclusions

About 25% of NH residents were continent. Double incontinence and urinary incontinence only were prevalent conditions in NHs, while FI alone was rarer. With the exception of diarrhea as a cause of FI, it appears that FI alone, UI alone, and DI may have common causes and development. Neurourol. Urodynam. 34:362–367, 2015. © 2014 The Authors.

Prevalence and correlates of fecal incontinence among nursing home residents: a population-based cross-sectional study

Background

Fecal incontinence is highly prevalent among nursing home residents. Previous nursing home studies have identified co-morbidity associated with fecal incontinence, but as this population is increasingly old and frail, we wanted to see if the rate of fecal incontinence had increased and to investigate correlates of fecal incontinence further.

Methods

Cross-sectional study of the entire nursing home population in one Norwegian municipality. Registered nurses filled in a questionnaire for all residents in the municipality (980 residents aged ≥65). Statistical methods used are descriptive statistics, binary logistic regression and multivariable logistic regression.

Results

The response rate of the study was 90.3%. The prevalence of fecal incontinence was 42.3%. In multivariable analysis of FI, residents with diarrhea (OR 7.33, CI 4.39-12.24), urinary incontinence (OR 2.77, CI 1.73-4.42) and dementia (OR 2.17, CI 1.28-3.68) had higher odds of having fecal incontinence compared to those without the condition. Residents residing in a nursing home between 4–5 years had higher odds of having fecal incontinence compared to residents who had stayed under a year (OR 2.65, CI 1.20-5.85). Residents with deficiency in feeding (2.17, CI 1.26-3.71), dressing (OR 4.03, CI 1.39-11.65), toilet use (OR 7.37, CI 2.65-20.44) and mobility (OR 2.54, CI 1.07-6.00) had higher odds of having fecal incontinence compared to residents without deficiencies in activities of daily living (ADL). Needing help for transfer between bed and chair was a protective factor for fecal incontinence compared to residents who transferred independently (OR 0.49, CI 0.26-0.91).

Conclusions

Fecal incontinence is a prevalent condition in the nursing home population and is associated with ADL decline, frailty, diarrhea and quality of care. This knowledge is important for staff in nursing home in order to provide the best treatment and care for residents with fecal incontinence.

The relationship between etiology, symptom severity and indications of surgery in cases of anal incontinence: a 25-year analysis of 1,046 patients at a tertiary coloproctology practice

BACKGROUND

The etiology of anal incontinence (AI) is often multifactorial. There is little data on the relationship between the etiology of AI, symptom severity, and the need for surgery. The aim of our study was to investigate this association in a large number of unselected patients with AI referred to a tertiary specialist coloproctological practice.

METHODS

Patients with AI seen at our unit between 1983 and 2008 were analyzed. The main etiologies were categorized as congenital, traumatic, neurologic, idiopathic, post-operative, post-obstetric, secondary to rectal prolapse, or inflammatory bowel disease. The severity of AI was graded using the validated Pescatori incontinence scale.

RESULTS

Overall, 1,046 patients were studied. The AI score was higher in patients with congenital (4.7 ± 1.1), traumatic (4.6 ± 1.4), and neurological (4.4 ± 1.2) incontinence. Surgical treatment was indicated in 214 cases (20.5%). Patients with AI related to trauma and congenital anomalies required surgery in 43.5 and 31.4% of cases, respectively, a percentage significantly higher than that for patients with other etiologies (P = 0.002). Prolapse-related AI usually responded to correction of the prolapse.

CONCLUSIONS

Patients with congenital, traumatic, and neurological AI tend to have greater symptom severity. Traumatic, rectal prolapse-related, and congenital AI cases more often require surgery.

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.
