Fecal incontinence quality of life scale

PURPOSE: This goal of this research was to develop and evaluate the psychometrics of a health-related quality of life scale developed to address issues related specifically to fecal incontinence, the Fecal Incontinence Quality of Life Scale. METHODS: The Fecal Incontinence Quality of Life Scale is composed of a total of 29 items; these items form four scales: Lifestyle (10 items), Coping/Behavior (9 items), Depression/Self-Perception (7 items), and Embarrassment (3 items). RESULTS: Psychometric evaluation of these scales demonstrates that they are both reliable and valid. Each of the scales demonstrate stability over time (test/retest reliability) and have acceptable internal reliability (Cronbach alpha >0.70). Validity was assessed using discriminate and convergent techniques. Each of the four scales of the Fecal Incontinence Quality of Life Scale was capable of discriminating between patients with fecal incontinence and patients with other gastrointestinal problems. To evaluate convergent validity, the correlation of the scales in the Fecal Incontinence Quality of Life Scale with selected subscales in the SF-36 was analyzed. The scales in the Fecal Incontinence Quality of Life Scale demonstrated significant correlations with the subscales in the SF-36. CONCLUSIONS: The psychometric evaluation of the Fecal Incontinence Quality of Life Scale showed that this fecal incontinence-specific quality of life measure produces both reliable and valid measurement.

Primary symptomless colonisation by Clostridium difficile and decreased risk of subsequent diarrhoea

BACKGROUND Little is known about whether patients who develop Clostridium-difficile-associated diarrhoea (CDAD) are culture-positive or culture-negative before illness. The most important risk factor is antibiotic exposure. We aimed to find out whether patients identified as primary symptom-free C difficile carriers are at higher risk of developing CDAD than patients who are culture-negative. METHOD We reviewed four longitudinal studies in which 810 patients admitted to hospital were followed up by prospective rectal-swab culture. At least two consecutive weekly cultures were obtained. We calculated the difference in risk of CDAD between colonised and non-colonised patients in each study and combined the results of the four studies in a random-effects model. FINDINGS Of 618 non-colonised patients (mean follow-up 1.7 weeks [SD 1.3]), 22 (3.6%) developed CDAD, whereas only two (1.0%) of 192 primary symptom-free carriers (1.5 [1.5]) developed CDAD (pooled risk difference -2.3% [95% CI 0.3-4.3], p=0.021). Of patients who received antibiotics, the risk difference was increased: 22 (4.5%) of 491 non-colonised patients compared with two (1.1%) of 176 colonised patients developed CDAD (-3.2% [0.4-6.0], p=0.024). Of the primary symptom-free C difficile carriers, 95 were colonised with toxigenic strains, 76 with non-toxigenic strains, 12 with both toxigenic and non-toxigenic strains (non-concurrently), and nine with strains of undetermined toxigenicity. Nine of the 12 toxogenic strains of C difficile isolates that cause CDAD were also recovered from stools of symptom-free patients. INTERPRETATION Primary symptomless C difficile colonisation is associated with a decreased risk of CDAD. Although the mechanism is unknown, risk reduction is found in colonisation with non-toxigenic and toxigenic strains.

Incontinence-associated dermatitis: a consensus.

Incontinence-associated dermatitis (IAD) is an inflammation of the skin that occurs when urine or stool comes into contact with perineal or perigenital skin. Little research has focused on IAD, resulting in significant gaps in our understanding of its epidemiology, natural history, etiology, and pathophysiology. A growing number of studies have examined clinical and economic outcomes associated with prevention strategies, but less research exists concerning the efficacy of various treatments. In the clinical and research settings, IAD is often combined with skin damage caused by pressure and shear or related factors, sometimes leading to confusion among clinicians concerning its etiology and diagnosis. This article reviews existing literature related to IAD, outlines strategies for assessing, preventing, and treating IAD, and provides suggestions for additional research needed to enhance our understanding and management of this common but under-reported and understudied skin disorder.

Supplementation with dietary fiber improves fecal incontinence.

BackgroundHuman studies have shown that dietary fiber affects stool composition and consistency. Because fecal incontinence has been shown to be exacerbated by liquid stools or diarrhea, management strategies that make stool consistency less loose or liquid may be useful. ObjectiveTo compare the effects of a fiber supplement containing psyllium, gum arabic, or a placebo in community-living adults who were incontinent of loose or liquid stools. Mechanisms underlying these effects (e.g., fermentation of the fibers and water-holding capacity of stools) were examined. MethodsThirty-nine persons with fecal incontinence of loose or liquid stools prospectively recorded diet intake and stool characteristics and collected their stools for 8 days prior to and at the end of a 31-day fiber supplementation period. During the fiber supplementation period, they ingested psyllium, gum arabic, or a placebo by random assignment. ResultsIn the baseline period, the groups were comparable on all variables measured. In the fiber supplementation period, (a) the proportion of incontinent stools of the groups ingesting the fiber supplements was less than half that of the group ingesting the placebo, (b) the placebo group had the greatest percentage of stools that were loose/unformed or liquid, and (c) the psyllium group had the highest water-holding capacity of water-insoluble solids and total water-holding capacity. The supplements of dietary fiber appeared to be completely fermented by the subjects as indicated by non-significant differences in total fiber, short chain fatty acids and pH in stools among the groups in the baseline or fiber supplementation periods. ConclusionsSupplementation with dietary fiber from psyllium or gum arabic was associated with a decrease in the percentage of incontinent stools and an improvement of stool consistency. Improvements in fecal incontinence or stool consistency did not appear to be related to unfermented dietary fiber.

Comparative effectiveness of Clostridium difficile treatments: a systematic review

BACKGROUND Clostridium difficile infection is increasing in incidence and severity. The optimal treatment is unknown. PURPOSE To determine whether, among adults with C. difficile infection, treatment with certain antibiotics compared with others results in differences in initial cure, recurrence, and harms. DATA SOURCES MEDLINE, AMED, ClinicalTrials.gov, and Cochrane databases (search dates: inception through August 2011, limited to English-language reports); bibliography review. STUDY SELECTION Randomized, controlled trials of adults with C. difficile infection, independent of outcomes, who were treated with medications available in the United States. Observational studies reporting strain were included. DATA EXTRACTION Study design, inclusion and exclusion criteria, quality and strength of evidence as assessed by 2 reviewers, study definitions, and duration of treatment and follow-up. Outcomes included initial cure, recurrence, and treatment harms. DATA SYNTHESIS 11 trials that included 1463 participants were identified. Three trials compared metronidazole with vancomycin; 8 compared metronidazole or vancomycin with another agent, combined agents, or placebo. Strain was analyzed in 1 trial and 2 cohort studies. No study comparing 2 antimicrobial agents demonstrated a statistically significant difference for initial cure; all comparisons were of low to moderate strength of evidence. Moderate-strength evidence from 1 study demonstrated that recurrence was decreased with fidaxomicin versus vancomycin (15% vs. 25%; difference, -10 percentage points [95% CI, -17 to -3 percentage points]; P=0.005). Subgroup analysis of a single study comparing metronidazole with vancomycin for patients who have severe C. difficile infection showed no difference by intention-to-treat analysis; this was rated as insufficient-strength evidence. Harms, when reported, did not differ between treatments in any study. LIMITATIONS Definitions of diarrhea, C. difficile infection, initial cure, and relapse varied. Some studies reported insufficient detail to allow assessment of all randomly assigned participants or of harms. CONCLUSION No antimicrobial agent is clearly superior for the initial cure of C. difficile infection. Recurrence is less frequent with fidaxomicin than with vancomycin.

Incontinence-Associated Dermatitis: A Comprehensive Review and Update

In 2009, a multinational group of clinicians was charged with reviewing and evaluating the research base pertaining to incontinence-associated dermatitis (IAD) and synthesizing this knowledge into best practice recommendations based on existing evidence. This is the first of 2 articles focusing on IAD; it updates current research and identifies persistent gaps in our knowledge. Our literature review revealed a small but growing body of evidence that provides additional insight into the epidemiology, etiology, and pathophysiology of IAD when compared to the review generated by the first IAD consensus group convened 5 years earlier. We identified research supporting the use of a defined skin care regimen based on principles of gentle perineal cleansing, moisturization, and application of a skin protectant. Clinical experience also supports application of an antifungal powder, ointment, or cream in patients with evidence of cutaneous candidiasis, aggressive containment of urinary or fecal incontinence, and highly selective use of a mild topical anti-inflammatory product in selected cases. The panel concluded that research remains limited and additional studies are urgently needed to enhance our understanding of IAD and to establish evidence-based protocols for its prevention and treatment.

Moisture-associated skin damage: Overview and pathophysiology

Moisture-associated skin damage (MASD) is caused by prolonged exposure to various sources of moisture, including urine or stool, perspiration, wound exudate, mucus, saliva, and their contents. MASD is characterized by inflammation of the skin, occurring with or without erosion or secondary cutaneous infection. Multiple conditions may result in MASD; 4 of the most common forms are incontinence-associated dermatitis, intertriginous dermatitis, periwound moisture-associated dermatitis, and peristomal moisture-associated dermatitis. Although evidence is lacking, clinical experience suggests that MASD requires more than moisture alone. Instead, skin damage is attributable to multiple factors, including chemical irritants within the moisture source, its pH, mechanical factors such as friction, and associated microorganisms. To prevent MASD, clinicians need to be vigilant both in maintaining optimal skin conditions and in diagnosing and treating minor cases of MASD prior to progression and skin breakdown.

An economic evaluation of four skin damage prevention regimens in nursing home residents with incontinence: economics of skin damage prevention.

Purpose To determine the cost and efficacy of 4 different regimens of incontinence-associated dermatitis (IAD) prevention in nursing home residents. Methods A multi-site open-label quasi-experimental study was conducted in 16 nursing homes stratified by location in 1 of 4 regions of the United States and randomly selected. In 3 of the 4 regimens, a moisture barrier ointment or cream of different compositions was applied after each episode of incontinence, and in 1 regimen, a polymer-based barrier film was applied 3 times per week. All regimens used a pH-balanced moisturizing cleanser. Time and motion measures were documented for the amount of skin care products used; the number, type, and time of caregivers performing IAD prevention care; and the number and type of supplies used. Rates of incontinence in each nursing home were determined during a 3-day surveillance period. Results A total of 1,918 nursing home residents were screened, and 51% (n = 981) qualified for prospective surveillance of incontinence dermatitis; the majority were female (80.1%) and elderly (96% ≥ 65 years old). A total of 78.6% (771/981) of the participants were incontinent of both urine and feces. Compared to the 3 regimens in which a barrier was applied after each episode of incontinence, the use of a regimen in which a barrier film was applied 3 times weekly had significantly lower costs for the barrier product, labor associated with barrier application, and total cost, which included products, labor, and supplies. There were also savings in total product (cleanser and barrier) and total labor costs. Conclusions The use of a defined skin care regimen that includes a cleanser and a moisture barrier is associated with a low rate of IAD in nursing home residents who are incontinent. Use of a polymer skin barrier film 3 times weekly is effective for preventing incontinence-associated skin breakdown and can provide significant cost savings.
