Incontinence-Associated Dermatitis, Characteristics and Relationship to Pressure Injury: A Multisite Epidemiologic Analysis

Risk Factors for Incontinence-Associated Dermatitis in Critically Ill Patients with Incontinence: A Systematic Review and Meta-analysis

PURPOSE

This systematic review analyzed evidence related to risk factors for Incontinence Associated Dermatitis (IAD) in critically ill incontinent patients.

METHOD

Systematic review and meta-analysis.

SEARCH STRATEGY

Eight databases, including PubMed, Embase, CINAHL, Cochrane Library, and Web of Science, were searched for studies published in the English language. The China National Knowledge Infrastructure, WanFang Data, and Chinese Scientific Journal Database were also searched for studies evaluating risk of IAD in critically ill incontinent patients published in the Chinese language.

FINDINGS

Twenty-four studies with moderate-to-high methodological quality were included. Significant risk factors for developing IAD were being older [odds ratio (OR) = 1.06, 95% confidence interval (CI): 1.02-1.10, P = .007], fever (OR = 2.57, 95% CI: 1.87-3.57, P < .00001), diagnosed with consciousness disorder (OR = 5.70, 95% CI: 2.28-14.22, P = .0002), having higher Acute Physiology and Chronic Health Evaluation (APACHE) II score (OR = 1.71, 95% CI: 1.25-2.35, P = .0009), lower Braden score (OR = 0.73, 95% CI: 0.56-0.96, P = .02), lower oxygen saturation (OR = 2.76, 95% CI: 1.52-5.00, P = .0008), double incontinence (OR = 4.10, 95% CI: 2.34-7.17, P < .00001), liquid stool (OR = 6.55, 95% CI: 4.12-10.41, P < .00001), frequent incontinence (OR = 1.21, 95% CI: 1.03-1.43, P = .02), and higher perineal assessment tool (PAT) score (OR = 3.18, 95% CI: 1.76-5.76, P = .0001).

IMPLICATIONS

Findings of this systematic review and meta-analysis suggest that healthcare providers should consider risk factors such as older age, fever, consciousness disorder, higher APACHE II score, lower Braden score and double incontinence matter when developing strategies for the prevention and management of IAD in critically ill incontinent patients.

Effects of a mattress cover with special airflow technology on the structure and function of the sacral and heel skin during loading: A two-arm exploratory crossover trial

Prolonged mechanical loading of the skin and underlying soft tissue cause pressure ulceration. The use of special support surfaces are key interventions in pressure ulcer prevention. They modify the degree and duration of soft tissue deformation and have an impact on the skin microclimate. The objective of this randomized cross-over trial was to compare skin responses and comfort after lying for 2.5 h supine on a support surface with and without a coverlet that was intended to assist with heat and moisture removal at the patient/surface interface. In addition, physiological saline solution was administered to simulate an incontinence episode on the mattress next to the participants' skin surface. In total, 12 volunteers (mean age 69 years) with diabetes mellitus participated. After loading, skin surface temperature, stratum corneum hydration and skin surface pH increased, whereas erythema and structural stiffness decreased at the sacral area. At the heel skin area, temperature, erythema, and stratum corneum hydration increased. These results indicate occlusion and soft tissue deformation which was aggravated by the saline solution. The differences in skin response showed only minor differences between the support surface with or without the coverlet.

Prognostic factors for the development of incontinence-associated dermatitis (IAD): A systematic review

Incontinence-associated dermatitis (IAD) is an irritant contact dermatitis from prolonged contact with urine or faeces, which can significantly impact patient comfort and quality of life. The identification of prognostic factors for the development of IAD has the potential to enhance management, support preventive measures and guide future research. The objective of this systematic review was to summarize the empirical evidence of prognostic factors for the development of IAD. This study included prospective and retrospective observational studies or clinical trials that described prognostic factors associated with IAD. There were no restrictions on setting, time, language, participants or geographical regions. Exclusion criteria included reviews, editorials, commentaries, methodological articles, letters to the editor, cross-sectional and case-control studies, and case reports. Searches were conducted from inception to April 2024 on MEDLINE, CINAHL, EMBASE and the Cochrane Library. The studies were assessed by two independent reviewers using the QUIPS and the CHARMS-PF for data extraction. A narrative synthesis approach was employed due to study heterogeneity and using the 'vote counting based on direction' method and the sign test. The overall certainty of evidence was assessed using adapted GRADE criteria. The review included 12 studies and identified 15 potential predictors. Moderate-quality evidence suggests that increased stool frequency, limited mobility and friction/shear problems are risk factors for IAD development. Female sex, older age, vasopressor use and loose/liquid stool are risk factors supported by low-quality evidence. Increased stool frequency, limited mobility and friction/shear problems seem to be risk factors for the development of IAD. There is insufficient evidence to support the predictive validity of female sex, older age, loose/liquid stool and vasopressor use. There is substantial methodological variability across studies, making it challenging to make comparisons. Large-scale cohort studies in different settings that incorporate our review findings should be conducted in the future.

Managing incontinence-associated dermatitis in the community: an overview

Incontinence-associated dermatitis (IAD) is often treated a hygienic challenge, rather than a serious condition with potentially life-threatening consequences. More appropriate education on the management strategies specific to IAD is required, in order for personalised and effective care that reflects the critical nature of this condition to be provided. Francesca Ramadan provides an overview of the key elements of best practice in IAD management and treatment.

Impact of an evidence-based bundle on incontinence-associated dermatitis prevalence in hospital patients: A quasi-experimental translational study

The study aimed to evaluate the effect of an intervention on the prevalence and severity of incontinence-associated dermatitis (IAD) in six hospitals in one state in Australia. This quasi-experimental pre-and post-study, conducted in 18 wards, was part of a larger implementation science study on incontinence-associated dermatitis. Skin and incontinence assessments were conducted on patients during February and March 2020 (pre-intervention) and July and August 2021 (post-intervention). The intervention comprised continence assessment and management, an education brochure for patients, family and caregivers on IAD, the Ghent Global IAD Categorisation Tool (GLOBIAD) and a skin care regime with patient skin protection measures (three-in-one barrier cream cloths, minimisation of bed protection layers, use of appropriate continence aid). A total of 1897 patients were assessed (pre-intervention = 964, post-intervention = 933). A total of 343 (35.6%) pre-intervention patients and 351 (37.6%) post-intervention patients had incontinence. The prevalence of hospital-acquired IAD was 6.71% in the pre-intervention group and 4.27% in the post-intervention group; a reduction of 36.3% (p = 0.159) despite higher patient acuity, prevalence of double incontinence and the COVID-19 pandemic in the post-intervention group compared with the pre-intervention group. Our multisite best practice IAD prevention and treatment intervention was able to reduce the prevalence and severity of hospital-acquired IAD, suggesting enduring effectiveness of the intervention.

Detecting and monitoring incontinence associated dermatitis: Does impedance spectroscopy have a part to play?

In this review, current understanding of the prevention and treatment of Incontinence Associated Dermatitis (IAD) is discussed. The need for preventative measures which target specific faecal/urinary irritants is highlighted, including the role of urease inhibitors. There is no existing internationally and clinically accepted method to diagnose and categorise the severity of IAD. Diagnosis currently relies on visual inspection; non-invasive techniques to assess skin barrier function could remove subjectiveness, particularly in darker skin tones. Impedance spectroscopy is a non-invasive technique which can be used to monitor skin barrier function, supporting visual assessments. Six studies (2003-2021) which used impedance to assess dermatitis were reviewed; inflamed skin was distinguishable from healthy skin in each case. This suggests that impedance spectroscopy could be useful in diagnosis early-stage IAD, potentially enabling earlier intervention. Finally, the authors present their initial findings on the role of urease in skin breakdown in an in vivo IAD model, using impedance spectroscopy.

The multi-factorial modes of action of urease in the pathogenesis of incontinence associated dermatitis

Background

Incontinence Associated Dermatitis (IAD) is a type of skin inflammation caused by chronic exposure to urine and/or faeces. Current treatment strategies involve creating a barrier between the skin and urine/faeces rather than targeting specific irritants. Urease expressing pathogens catalyse the conversion of urea, present in urine, into ammonia. The accumulation of ammonia causes an elevation in skin pH which is believed to activate faecal enzymes which damage skin, and opportunistic pathogens, which lead to secondary infections.

Objectives

To develop a better, multi-factorial model of IAD pathogenesis, including the effect of urease-expressing bacteria on skin, mechanism of damage of urease and urease-triggered activity of faecal enzymes and secondary pathogens. To study the effect of urease inhibition on preventing IAD skin damage.

Methods

Five separate studies were made using ex vivo porcine skin and in vivo human skin models. Measurements of the change in skin barrier function were made using skin impedance, trans-epidermal water loss (TEWL), stratum corneum moisture and pH. Skin was exposed to artificial urine, inoculated with various microbes, enzymes and chemicals to examine the influence of: 1) urease-positive Proteus mirabilis 2) ammonia, 3) combination of P. mirabilis and a faecal enzyme, trypsin, 4) combination of P. mirabilis and opportunistic pathogens, Candida albicans and Staphylococcus aureus, 5) inhibition of urease using acetohydroxamic acid (AHA) on barrier function.

Results

The urease-mediated production of ammonia had two principal effects: it elevated skin pH and caused inflammation, leading to significant breakdown in skin (stratum corneum) barrier function. Urease was found to further increase the activity of faecal enzymes and opportunistic pathogens, due to elevated skin pH. The urease inhibitor, AHA, was shown to have significantly reduced damage to skin barrier function, measured as its electrical resistance.

Conclusions

Targeted therapeutic strategies should be developed to prevent the manifestation of IAD, rather than creating a generic barrier between skin and urine/faeces. Urease has been identified as a crucial component in the manifestation of IAD, due to its role in the production of ammonia. Urease inhibition provides a promising therapeutic target to halt the progression of IAD.

Incontinence-associated dermatitis in older adults in residential care settings: a point prevalence study

Incontinence-associated dermatitis (IAD) is a skin inflammation caused by contact with urine or faeces or both. It has a negative effect on the patient's quality of life and is indicative of the care provided. However, globally there is a lack of empirical data on the prevalence of IAD.

AIM

To identify, for the first time, the proportion of older adults in extended care settings in Ireland affected by IAD.

DESIGN

Cross-sectional, multisite, point prevalence survey, across three community extended care settings for older people in Ireland.

METHODS

Two clinical nurse specialists, using the Scottish Excoriation and Moisture Related Skin Damage Tool, identified the presence of IAD through clinical observation and visual skin inspection. IAD prevalence was calculated for the total population and incontinent population sets using percentages and confidence intervals (CI).

RESULTS

The prevalence of incontinence was 86.4% (n=165), a significantly higher proportion were female (P=0.003). The point prevalence of IAD across the total population and incontinent population was 11.5% (22/191; 95% CI, 7.4-19.9%) and 13.3% (22/164; 95% CI, 8.5-19.5%), respectively. Being incontinent was associated with being female, more dependent (Barthel), having possible cognitive impairment, poorer mobility (Braden and Waterlow) and a high risk of pressure ulcers (Waterlow). A logistic regression analysis found no predictor variables for IAD among the variables that met the cut-off point for this analysis.

CONCLUSIONS

The study provides the first point prevalence empirical data on the occurrence of IAD in Ireland. It can inform decision-making on future planning and budgeting of new quality improvement projects and act as a benchmark for ongoing auditing of IAD.

Care Needs of Older Adults With Urinary Incontinence: A Cross-Sectional Study

PURPOSE

To explore care requirements of older adults with urinary incontinence (UI) and contributing factors.

METHOD

This cross-sectional study used the Older Adults Urinary Incontinence Care Needs Inventory to survey participants with UI in three large-scale tertiary hospitals located in Guangzhou City, China, from January 2023 to November 2023. Statistical analyses, including analysis of variance, t tests, correlation analyses, and linear regression models, were conducted to assess factors influencing participants' care needs.

RESULTS

A total of 530 older adults with UI participated in the survey and mean standardized score for overall care needs was 78.65 (SD = 5.01), with mean scores for each dimension ranging from 70.88 (SD = 10.55) for social participation needs to 82.45 (SD = 7.11) for health education needs. Factors that were found to influence incontinence care needs in older adults included age, literacy level, number of leaks, and type of disease (F = 37.07, adjusted R2 = 0.290, p < 0.001).

CONCLUSION

Comprehensive care for older adults with UI, encompassing physiological, psychological, and social aspects, is crucial. It is essential to tailor care to individual needs and characteristics, taking into account factors, such as age and education, to ensure effective care.

Knowledge of nursing staff before and after training on incontinence-associated dermatitis

OBJECTIVE

To verify the knowledge of nursing staff before and after training on incontinence-associated dermatitis.

METHOD

A study before and after an educational intervention carried out with nursing staff from the medical and surgical clinics and intensive care unit of the university hospital in June 2023. The training took place over three meetings. Data was collected using a questionnaire administered immediately before and after the training. McNemar's test for dependent samples was used to compare before and after training.

RESULTS

25 nurses and 14 nursing technicians took part. The items that showed statistical significance were related to the identification and correct differentiation of dermatitis associated with incontinence and pressure injury; and the correct way to sanitize the skin.

CONCLUSION

The training of the nursing team made it possible to assess their knowledge of how to identify, prevent and treat incontinence-associated dermatitis.

The Prevalence of Incontinence and Its Association With Urinary Tract Infections, Dermatitis, Slips and Falls, and Behavioral Disturbances Among Older Adults in Medicare Fee-for-Service

PURPOSE

The purpose of this study was to examine the prevalence of urinary (UI), fecal (FI), and dual incontinence (DI) in older adults and their association with urinary tract infections, dermatitis, slips and falls, and behavioral disturbances based on Medicare fee-for-service (FFS) claims data.

DESIGN

Retrospective analysis.

SUBJECTS AND SETTINGS

Data from administrative claims from the CMS Medicare Limited Data Set (5% sample) for all months in 2018 were reviewed. The analysis was limited to FFS Medicare beneficiaries, with minimum of 3-month enrollment in Parts A and B who were at least 65 years old. This cohort included 1.2 million beneficiaries in the United States.

METHODS

We used diagnosis codes to identify members with incontinence and grouped these members into 3 categories (UI only, FI only, and DI). We also divided claims based on 4 sites of care (nursing home, skilled nursing facility, home health, and self- or family care). We then determined the prevalence of (1) urinary tract infections (UTIs), (2) dermatitis, (3) slips and falls, and (4) behavioral disturbances for each type of incontinence.

RESULTS

We found that 11.2% of Medicare members had a claims-based diagnosis of incontinence in 2018. On average, those diagnosed with incontinence experienced 5 times more UTIs, 2 times as many dermatitis events, more than twice as many slips and falls, and 2.8 times more behavior disturbances compared to those without an incontinence diagnosis. For those with DI, the prevalence of the 4 outcomes was significantly higher (between 22% and 185%) compared to those with UI only.

CONCLUSIONS

Findings show that Medicare beneficiaries diagnosed as incontinent experience a much higher prevalence of UTIs, dermatitis, slips and falls, and behavioral disturbances compared to those without a diagnosis of incontinence. Our results suggest that incontinence may be an important indicator diagnosis for multiple other conditions and, if not well-managed, may challenge the desire for those who are incontinent to age at home.

Descriptive Analysis of Surgical Outcomes and Stoma Formation for Treating Sacral and Anal Pressure Injuries in Spinal Cord Injury: A Retrospective Study of Selected Cases

Introduction

Pressure injuries (PIs) arise from sustained pressure on tissue, leading to reduced blood flow to the affected area. In patients with spinal cord injuries (SCIs), these PIs can significantly diminish their independence and overall quality of life. This research sought to assess the frequency of surgical complications in treatment regimens for large sacral PIs involving the anus. Specifically, the study focused on the incorporation of stoma formation in patients with SCIs.

Methods

A retrospective review identified 25 SCI patients who had extensive sacral PIs. These patients underwent intestinal stoma formation as a preparatory step before plastic reconstructive surgery to address the wounds between 2015 and 2020.

Results

Successful wound closure was achieved in all instances. Notably, each patient had experienced a minimum of three unsuccessful reconstructive surgeries elsewhere before this intervention. The observed rate of surgical complications aligned with findings from previous analogous studies.

Conclusion

While often viewed as a treatment of last resort, an intestinal stoma might serve as a valuable strategy, particularly for SCI patients with extensive PIs near the anal region, to promote the healing of such injuries. Tailored decision-making is essential to ensure the best possible patient outcomes.

Incontinence-Associated Dermatitis in Older Intensive Care Patients: A Review and Case Report

Background

Incontinence-Associated Dermatitis is a serious skin injury causing suffering, secondary infection, and inducing almost six times more pressure sore than normal skin patients. This moisture and chemical skin irritation is a concern, especially for intensive care unit nurses. This study aimed to review the effective nursing strategy for preventing and caring for incontinence-associated dermatitis in older intensive care unit patients and pilot its feasibility.

Methods

The five databases, including PubMed, Google Scholar, CINAHL Complete, WanFang, and CNKI, were searched, and articles were screened and extracted. The strategies and details of prevention and care for incontinence-associated dermatitis were reviewed and summarized. Finally, selected strategies were applied to five intensive care unit patients with various health conditions and levels of Incontinence-Associated Dermatitis severity.

Results

The literature review found that there is a standardized nursing process for incontinence-associated dermatitis. The prevention and care strategies for incontinence-associated dermatitis include assessment, risk factor management, skin cleaning, skin protection, and health education and training. In actual clinical application, personalized nursing measures can positively impact patients. Five case studies from our pilot confirmed this finding.

Conclusion

Personalized nursing measures can positively impact patients in actual clinical applications. Our five case studies implementing the strategies from the review confirmed this finding. In clinical work, it is recommended to develop personalized nursing programs for specific risk factors of older intensive care unit patients.

The Effects of Incontinence Pad Application on Loaded Skin With Reference to Biophysical and Biochemical Parameters: An Exploratory Cohort Study Using a Repeated-Measures Design

PURPOSE

The purpose of this study was to evaluate temporal changes in skin responses following exposure to moisture alone or moisture in combination with mechanical loading.

DESIGN

Comparison cohort with a repeated-measures design.

SUBJECTS AND SETTINGS

The sample comprised 12 healthy volunteers. Participants were purposely sampled from 2 different age groups; half were 32 to 39 years old and half were 50 to 62 years old. Participants identified as White, Black, or mixed; 83% (n = 10) identified as White; 8 (67%) were female.

METHODS

Four sites at the sacrum were challenged with the application of specimens taken from 2 absorbent products; the pad specimens were applied dry or saturated with synthetic urine (SU; pH = 8); a further site from the sacral skin was also selected and used as a control. Skin assessments were performed at different points in time: (1) 60 minutes after exposure to dry or SU-saturated pad specimens; (2) 60 minutes after exposure to pads and mechanical loading (application of pressure in the form of 45°C high sitting); and (3) 30 minutes after removal of all pads (recovery period). Outcome measures were transepidermal water loss (TEWL), stratum corneum (SC) hydration, erythema, pH, and skin inflammatory biomarkers measured at each of the time points described earlier.

RESULTS

The control site and those exposed to dry pads showed minimal time-dependent changes irrespective of the parameter investigated. In contrast, significant increases in TEWL (P = .0000007) and SC hydration responses (P = .0000007) were detected at the sites under absorbent pad specimens after saturation with SU (exposure to moisture). In some participants, TEWL and SC hydration parameters were significantly higher during pressure application. Skin pH remained in the mildly acidic range throughout the test session, and no consistent trends were observed with erythema. Skin inflammatory biomarkers also exhibited considerable variability across participants; none changed significantly over time. Significant differences (P = .02) were also detected following the exposure of moisture in combination with pressure.

CONCLUSION

We evaluated an array of parameters to identify changes following skin exposure to 2 absorbent pads in the presence and absence of SU and mechanical loading. Analysis revealed changes in skin barrier properties in the presence of moisture and/or pressure. This observation suggests a need for frequent pad changing as well as periods of skin off-loading to protect the skin health of individuals with incontinence.

What are the prognostic factors for the development of incontinence-associated dermatitis (IAD): a protocol for a systematic review and meta-analysis

INTRODUCTION

Incontinence-associated dermatitis (IAD) is irritant contact dermatitis and skin damage associated with prolonged skin contact with urine and/or faeces. Identifying prognostic factors for the development of IAD may improve management, facilitate prevention and inform future research.

METHODS AND ANALYSIS

This protocol follows the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. Prospective and retrospective observational studies or clinical trials in which prognostic factors associated with the development of IAD are described are eligible. There are no restrictions on study setting, time, language, participant characteristics or geographical regions. Reviews, editorials, commentaries, methodological articles, letters to the editor, cross-sectional and case-control studies, and case reports are excluded. MEDLINE, CINAHL, EMBASE and The Cochrane Library will be searched from inception until May 2023. Two independent reviewers will independently evaluate studies. The Quality in Prognostic Studies tool will be used to assess the risk of bias, and the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies-Prognostic Factors checklist will be used for data extraction of the included studies. Separate analyses will be conducted for each identified prognostic factor, with adjusted and unadjusted estimated measures analysed separately. Evidence will be summarised with a meta-analysis when possible, and narratively otherwise. The Q and I² statistics will be calculated in order to quantify heterogeneity. The quality of the evidence obtained will be evaluated according to the Grades of Recommendation Assessment, Development and Evaluation guidance.

ETHICS AND DISSEMINATION

No ethical approval is needed since all data is already publicly accessible. The results of this work will be published in a peer-reviewed scientific journal.

The diagnosis, management and prevention of intertrigo in adults: a review

Intertrigo is a common inflammatory skin disorder caused by skin-on-skin friction in skin folds, due to moisture becoming trapped because of poor air circulation. This can occur in any area of the body where two skin surfaces are in close contact with each other. The aim of this scoping review was to systematically map, review and synthesise evidence on intertrigo in adults. We identified a wide range of evidence and performed a narrative integration of this related to the diagnosis, management and prevention of intertrigo. A literature search was conducted within the following databases: Cochrane Library, MEDLINE, CINAHL, PubMed and EMBASE. After reviewing articles for duplicates and relevance, 55 articles were included. The incorporation of intertrigo in the ICD-11 provides a clear definition and should improve the accuracy of estimates. With regards to the diagnosis, prevention and management of intertrigo, the literature demonstrates consensus among health professionals in approach and this forms the basis for the recommendations of this review: identify predisposing factors and educate patient in reducing these; educate patients in skin fold management and adopt structured skin care routine; treat secondary infection with appropriate topical agent; consider using moisture-wicking textiles within skin folds to reduce skin-on-skin friction, wick away moisture and reduce secondary infection. Overall, the quality of evidence on which to determine the strength of any recommendations for practice remains low. There remains the need for well-designed studies to test proposed interventions and build a robust evidence base.

A Booklet on the Assessment, Prevention, and Treatment of Incontinence-Associated Dermatitis

OBJECTIVE

Printed materials have been used as educational resources to assist healthcare professionals in evidence-based clinical practice by providing guidelines for treatment, prevention, and self-care. The aim of this study was to develop and validate a booklet on the risk assessment, prevention, and treatment of incontinence-associated dermatitis.

METHODS

This was a descriptive, analytic, and quantitative study. The booklet was developed in six steps: situational diagnosis, development of the research question, integrative review of the literature, synthesis of knowledge, structuring and design, and validation of the content. An expert panel composed of 27 experienced nurses carried out content validation using the Delphi technique. The content validity index (CVI) and Cronbach α coefficient were calculated.

RESULTS

The mean Cronbach α for the evaluation questionnaire was .91, indicating excellent internal consistency. The evaluators classified the content of the booklet from "inadequate" to "totally adequate" (overall CVI, 0.91) in the first round of consultation and from "adequate" and "totally adequate" (overall CVI, 1.0) in a second round of consultation. The booklet was therefore considered validated.

CONCLUSIONS

A booklet on risk assessment, prevention, and treatment of incontinence-associated dermatitis was created and validated by an expert panel, obtaining 100% consensus among the evaluators in the second round of consultation.

The effectiveness of the Attends Product Selector Tool in continence management in a care home setting

Qualified nurses are accountable for selecting a suitable containment product for care home residents, which can be challenging for both the resident and health professional. Absorbent incontinence products are the most commonly used products for containing leakage. The purpose of this observational study was to review and understand how effective the Attends Product Selector Tool is when used to assess a resident for an appropriate disposable incontinence product and the in-use experience of products in relation to containment, product use and effectiveness. The study was undertaken in three care homes, with 92 residents who had an initial assessment undertaken either by an Attends Product Manager or a nurse trained in how to use the tool. A total of 316 products over a 48-hour period were individually assessed by the observer to check the time the pad was changed, the type of pad used, the voided volume in the pad and if the pad had leaked. The results showed that some residents had their products changed inappropriately. Not all residents were using the products that best suited their assessment; this mostly occurred at night. Overall, the tool was effective in enabling staff to select an appropriate style of containment product. However, when it came to selecting the absorbency, the assessor tended to choose a higher absorbency rather than starting at the lower absorbency in the product guide range. The observer found the assessed product was not always used and was sometimes changed inappropriately due to lack of communication and staff turnover.

Cross-setting Comparison of Risk Factors for Pressure Injuries Acquired in Post-Acute Care

GENERAL PURPOSE

To provide information on the association between risk factors and the development of new or worsened stage 2 to 4 pressure injuries (PIs) in patients in long-term care hospitals (LTCHs), inpatient rehabilitation facilities (IRFs), and skilled nursing facilities (SNFs).

TARGET AUDIENCE

This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.

LEARNING OBJECTIVES/OUTCOMES

After participating in this educational activity, the participant will:1. Compare the unadjusted PI incidence in SNF, IRF, and LTCH populations.2. Explain the extent to which the clinical risk factors of functional limitation (bed mobility), bowel incontinence, diabetes/peripheral vascular disease/peripheral arterial disease, and low body mass index are associated with new or worsened stage 2 to 4 PIs across the SNF, IRF, and LTCH populations.3. Compare the incidence of new or worsened stage 2 to 4 PI development in SNF, IRF, and LTCH populations associated with high body mass index, urinary incontinence, dual urinary and bowel incontinence, and advanced age.

Effectiveness of an External Urinary Device for Female Anatomy and Trends in Catheter-Associated Urinary Tract Infections

PURPOSE

The purpose of this study was to examine the effectiveness of an external female urinary management system (external urinary device for female anatomy [EUDFA]) in critically ill women unable to self-toilet and to identify rates of indwelling catheter use, catheter-associated urinary tract infections (CAUTIs), urinary incontinence (UI), and incontinence-associated dermatitis (IAD) before and after the introduction of the EUDFA.

DESIGN

Prospective, observational, and quasi-experimental design.

SUBJECTS AND SETTING

The sample comprised 50 adult female patients in 4 critical/progressive care units using an EUDFA at a large academic hospital in the Midwestern United States. All adult patients in these units were included in the aggregate data.

METHODS

Prospective data collected from the adult female patients over 7 days included urine diverted from the device to a canister and total leakage. Aggregate unit rates of indwelling catheter use, CAUTIs, UI, and IAD were retrospectively examined during 2016, 2018, and 2019. Means and percentages were compared using t tests or chi-square tests.

RESULTS

The EUDFA successfully diverted 85.5% of patients' urine. Indwelling urinary catheter use was significantly lower in 2018 (40.6%) and 2019 (36.6%) compared with 2016 (43.9%) (P < .01). The rate of CAUTIs was lower in 2019 than in 2016, but not significantly (1.34 per 1000 catheter-days vs 0.50, P = .08). The percentage of incontinent patients with IAD was 69.2% in 2016 and 39.5% in 2018-2019 (P = .06).

CONCLUSIONS

The EUDFA was effective in diverting urine from critically ill female incontinent patients and indwelling catheter utilization.

The Influence of Absorbent Products on Skin Integrity: A Scoping Review

PURPOSE

Absorbent products are commonly used to absorb urine and fecal matter and to mitigate potential skin complications such as incontinence-associated dermatitis (IAD). Evidence concerning the effect these products have on skin integrity is limited. This scoping review aimed to explore the evidence/literature on the effect of absorbent containment products on skin integrity.

METHOD

A scoping literature review.

SEARCH STRATEGY

The electronic databases CINAHL, Embase, MEDLINE, and Scopus were searched for published articles between 2014 and 2019. Inclusion criteria were studies that focused on urinary and/or fecal incontinence, use of incontinent absorbent containment products, impact on skin integrity, and published in English. The search identified a total of 441 articles that were identified for the title and abstract review.

FINDINGS

Twelve studies met inclusion criteria and were included in the review. Variability in the study designs did not allow firm conclusions regarding which absorbent products contributed to or prevented IAD. Specifically, we found variations in assessment of IAD, study settings, and types of products used.

IMPLICATIONS

There is insufficient evidence to support the effectiveness of one product category over another for maintaining skin integrity in persons with urinary or fecal incontinence. This paucity of evidence illustrates the need for standardized terminology, a widely used instrument for assessment of IAD, and identification of a standard absorbent product. Additional research using both in vitro and in vivo models, along with real-world clinical studies, is needed to enhance current knowledge and evidence of the impact of absorbent products on skin integrity.

The effectiveness of a hydrocolloid crusting method versus standard care in the treatment of incontinence-associated dermatitis among adult patients in an acute care setting: A randomised controlled trial

INTRODUCTION

Incontinence-associated dermatitis (IAD) is a type of irritant contact dermatitis due to prolonged exposure of the skin to moisture induced by urine or/and faeces. The main principles when treating IAD involves protecting the skin from further exposure to irritants, establishing a healing environment, and eradicating skin infections. This study aimed to evaluate the effectiveness of the hydrocolloid crusting method (HCM) versus the standard care method (SCM) in treating IAD.

METHOD

A randomised controlled trial was conducted in an acute tertiary hospital in Singapore between August 2019 to September 2021. Using computer-generated numbers, patients were randomised into either HCM or SCM treatment groups. HCM treatment involved cleansing the affected area with a pH-neutral non-rinse moisturising cleanser, and the application of alternate layers of hydrocolloid powder, and non-sting film barrier spray (repeated three times during each use). Patients in the SCM treatment group received the same cleanser followed by a 30% zinc oxide barrier cream. IAD was assessed daily for up to seven days by the wound care nurses using the IAD severity tool. The primary outcome of the study was the mean difference in IAD score per day between both methods.

RESULTS

Forty-four patients were eligible and recruited (22 in HCM; 22 in SCM). Patients in both groups were comparable in age and gender. IAD Category 2 was more predominant in both methods. The most common location of IAD was at the perianal skin and diarrhea related to gastroenteritis was the most prevalent cause of IAD. More patients in the SCM group (n = 12; 54.5%) had their IAD healed within seven days compared to HCM, (n = 7; 31.8%) group. However, the average decrease in IAD scores per day for both methods were found to be similar.

CONCLUSION

HCM can be considered as a treatment of IAD along with the use of SCM. A skin care regimen should include effective cleansing, skin protection, and moisturization in IAD management.

Risk factors for nursing home admission among older adults: Analysis of basic movements and activities of daily living

This retrospective study aimed to clarify the risk of older adults' nursing home placement in terms of basic movements and activities of daily living (ADLs) by analyzing data from a long-term care insurance certification survey in 2016‒2018 in City A. Of the 21,520 people certified as needing care, 16,865 could be followed up until 2018. Data on sex, age, household structure, and level of care required were obtained. Those who lived at home and at nursing homes were categorized as the "Unchanged group" and the "Changed group," respectively. Multivariate binomial logistic regression analysis was performed, with group type as the dependent variable and basic movement and ADL scores as the independent variables. For factor analysis according to care level, participants were classified into support need levels 1 and 2, care need levels 1 and 2, and care need levels 3, 4, and 5. For those categorized into support need levels 1 and 2, standing on one leg and transferring (basic movements) and urination and face cleaning (ADLs) were associated with nursing home placement. For those in care need levels 1 and 2, getting up and transferring (basic movements) and bathing, urination, face cleaning, and hair styling (ADL) were significantly associated with nursing home placement. For those in care need levels 3, 4, and 5, sitting and transferring (basic movements) and self-feeding and defecation (ADL) were significant. Occupational therapists must focus on older adults' declining ADLs and basic movements and relay the necessary information to patients, families, and other healthcare professionals to ensure appropriate and prompt care delivery.

Risk factors of incontinence-associated dermatitis among critically ill patients: A systematic review and meta-analysis

Objectives

Incontinence-associated dermatitis (IAD) is increasingly found among critically ill patients, but the risk factors for IAD in these patients are currently unclear. The purpose of this meta-analysis was to identify the risk factors of IAD in critically ill patients.

Methods

Web of Science, PubMed, EMBASE, and Cochrane Library were systemically searched until July 2022. The studies were selected based on inclusion criteria, and data were independently extracted by two researchers. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the included studies. Odds ratios (ORs) and their associated 95% confidence intervals (CIs) were used to identify significant differences in the risk factors. The I ² test was used to estimate the heterogeneity of studies, and Egger's test was used to assess the potential publication bias.

Results

A total of 7 studies enrolling 1,238 recipients were included in the meta-analysis. Age ≥ 60 (OR = 2.18, 95% CI: 1.38~3.42), female sex (OR = 1.76, 95% CI: 1.32~2.34), dialysis (OR = 2.67, 95% CI: 1.51~4.73), fever (OR = 1.55, 95% CI: 1.03~2.33), vasoactive agent (OR = 2.35, 95% CI: 1.45~3.80), PAT score ≥ 7 (OR = 5.23, 95% CI: 3.15~8.99), frequency of bowel movement > 3times/d (OR = 5.33, 95% CI: 3.19~8.93), and liquid stool (OR = 2.61, 95% CI: 1.56~4.38) were the risk factors of IAD among critically ill patients.

Conclusions

Many risk factors are related to IAD among critically ill patients. Nursing staff should pay more attention to evaluating the risk of IAD and enhance the care of high-risk groups.

Efficacy of modified isolation in incontinence associated dermatitis

OBJECTIVE

To analyze the value of modified isolation in preventing the occurrence of incontinence associated dermatitis (IAD) in patients with incontinence, and to provide high value skin care intervention for the patients.

METHODS

Clinical data of 204 patients were collected for retrospective analysis. The patients were divided into a conventional group (conventional skin care protocol, n=102) and a modified group (modified isolation care protocol, n=102) according to the different treatment regimens. The differences in the incidence of IAD, time to IAD, required weekly care, cost of nursing supplies, perineal skin status and nursing satisfaction were compared between the two groups.

RESULTS

Compared with the conventional group, the modified group had a greatly lower incidence of IAD (42.16% vs. 2.94%), longer time to IAD occurrence (5.75±1.25 vs. 12.50±1.50), less required weekly care (43.05±8.41 vs. 13.54±2.57), lower cost of nursing supplies (330.16±98.44 vs. 115.53±32.58), and a better correlation between perineal skin status and nursing satisfaction (all P<0.05).

CONCLUSION

Modified isolation can greatly reduce the incidence of IAD in incontinent patients, improve their status of the perineal skin, increase patient satisfaction with care, and reduce the cost of required nursing supplies. So, modified isolation may serve as the preferred care protocol for incontinent patients.

INCONTINENCE-ASSOCIATED DERMATITIS: PREVALENCE AND ASSOCIATED FACTORS IN INTENSIVE CARE UNIT

Objective: To analyze the point prevalence of incontinence-associated dermatitis (IAD) and associated factors in adult patients admitted to Intensive Care Units (ICUs). Method: A cross-sectional, observational, retrospective study carried out with 105 patients in the ICU of three university hospitals located in the state of São Paulo. The demographic and clinical variables and IAD come from the database of the research project “Prevalence of pressure injuries in the Intensive Care Unit,” composed of information from medical records and physical examination. Data were analyzed using descriptive and inferential statistics. The study was approved by the Research Ethics Committee of the proposing institution. Results: Of the 105 patients, 58 (55.24%) were male, with a mean age of 55.76 years (SD = 16.39), 105 (91.3%) had a urinary catheter and 89.4% wore diapers. Ten patients had IAD, with a point prevalence of 9.52%. The factor associated with IAD was admission due to trauma (p = 0.02). Conclusion: Studies on IAD are essential for quality, well-structured and grounded nursing care, especially in the care of critically ill patients.

Prevalence of Friction Skin Injury on the Buttocks and/or Posterior Thighs in an Acute Care Setting: A Quality Improvement Project

PURPOSE

The prevalence of friction skin injury (FcI) in an acute care hospital was evaluated as part of a quality improvement initiative.

PARTICIPANTS/SETTING

The setting for this quality improvement project was an academic medical center with 728 licensed beds in the central plains of the United States. Data were collected by 33 clinicians: 28 were RN staff members and 5 were patient care technicians. Six of the 28 nurses (21%) were board-certified wound nurses and 2 (7%) were in training but not yet certified. Prevalence data were collected on 354 hospitalized patients.

APPROACH

Friction skin injuries were measured in conjunction with the institution's quarterly skin survey for the NDNQI PUPS (National Database of Nursing Quality Indicators Pressure Ulcer Prevalence Survey) in August 2019. The prevalence of FcI was calculated using the number of patients with FcI divided by the total number of patients surveyed.

OUTCOMES

Three hundred fifty-four patients completed the survey in this PUPS; FcI was diagnosed in 8 patients, yielding a prevalence rate of 2.3%. Clinical manifestations of FcI such as lichenification, skin/soft tissue discoloration, skin/soft tissue deformation and/or callus formation, and skin ulceration were also documented. In addition, a majority of patients with FcI were found to have fecal or urinary incontinence (n = 5/8, 63%; 2 had both fecal and urinary incontinence, 25%). Braden Scale for Pressure Sore Risk subscales scores were analyzed; the mean subscale score for moisture was 3.4; the mean subscale score for friction/shear was 1.4; the mean subscale score for activity was 2.6; and the mean subscale score for mobility was 2.9.

IMPLICATIONS FOR PRACTICE

To the best of my knowledge, this is the first published article documenting FcI prevalence in any care setting. Additional prevalence studies are needed to establish the epidemiology of FcI across care settings and in the community.

Urinary incontinence prevalence and management in nursing homes in Austria, the Netherlands, Turkey and the United Kingdom: A multi-site, cross-sectional study

OBJECTIVES

The aim of this study is to describe and compare the prevalence rates of urinary incontinence as well as the management of urinary incontinence in the nursing home setting in Austria, the Netherlands, Turkey and the UK.

METHODS

This study is a secondary analysis of the 2017 and 2018 data from a multi-site, cross-sectional study which is performed annually in the nursing home setting in Austria, the Netherlands, Turkey and the UK.

RESULTS

A total of 23,334 nursing home residents was included in this study, most of whom were female. The urinary incontinence prevalence rates ranged from 13.8% in Turkey to 35.1% in Austria. In all countries, the most frequently used intervention for urinary incontinence management was the use of absorbent products and/or catheters (ranging from 81% in Turkey to 94.5% in Austria). The countries differed with regard to the methods used to assess the type of urinary incontinence, scheduled individual bathroom visits and medication evaluation. In the UK (77.1%), scheduled individual bathroom visits were a more frequent measure than in Austria (51.3%), the Netherlands (24.4%) and Turkey (10.2%).

CONCLUSION

The most frequently used nursing intervention in all countries was the use of absorbent products and/or catheters. Future studies on the over- or misuse of these products are warranted. In order to avoid the over- or misuse of these products in the nursing home setting, the use of the evidence- and consensus-based algorithm provided by the Wound, Ostomy and Continence Nurses Society™ is recommended.

Comparison of two skin protection regimes for the Prevention of Incontinence-associated Dermatitis in geriatric care (PID): a study protocol for an exploratory randomised controlled pragmatic trial

INTRODUCTION

The majority of aged long-term care receivers and patients in geriatric acute care are affected by some form of incontinence. These individuals are at risk of developing incontinence-associated dermatitis (IAD), a common type of irritant contact dermatitis caused by repeated and prolonged direct contact of the skin with urine and stool. The prevalence of IAD in these settings is high. Preventive measures include mild skin cleansing and the application of skin protecting leave-on products. Available evidence is weak regarding the comparative performance of different skin protection strategies and products due to a lack of confirmatory trials using relevant comparators and endpoints. Therefore, the overall aim of this exploratory trial is to compare the effects of three skin protection strategies to estimate effect sizes of the recently published core outcomes in IAD research.

METHODS AND ANALYSIS

A pragmatic three-arm, assessor-blinded, randomised controlled, exploratory trial with parallel group design will be performed, comparing film-forming and lipophilic skin protecting leave-on products for IAD prevention with standard incontinence care alone. The trial will be conducted in geriatric nursing homes and geriatric acute care settings in the federal state of Berlin, Germany. A total of n=210 participants being incontinent of urine and stool will be included. Outcomes include IAD incidence, erythema, erosion, maceration, IAD-related pain, patient satisfaction, safety, feasibility and compliance. IAD incidence of the control and intervention groups will be compared to estimate effect sizes, and the procedural feasibility of the intervention will be tested to plan a possible subsequent confirmatory randomised controlled trial.

ETHICS AND DISSEMINATION

The study received the approval of the ethics committee of Charité-Universitätsmedizin Berlin (EA4/043/22). Results will be disseminated through peer-reviewed open-access journals and international conferences.

It was found that the Instagram can be adopted as a tool to carry out educational actions, including in a hospital environment.

Incontinence Management and Pressure Injury Rates in US Acute Care Hospitals: Analysis of Data From the 2018-2019 International Pressure Injury Prevalence™ (IPUP) Survey

PURPOSE

The purpose of this study was to identify and describe the prevalence of incontinence (urinary and/or fecal) and incontinence management practices among patients in US adult acute care settings, with and without hospital-acquired pressure injuries (HAPIs), using the data from the 2018/2019 International Pressure Ulcer Prevalence™ (IPUP) survey.

DESIGN

Observational, cohort study with cross-sectional data collection and retrospective data analysis.

SUBJECTS AND SETTING

The sample comprised 296,014 patients hospitalized in 1801 acute care facilities in the United States that participated in 2018 and/or 2019 IPUP survey. Of these, 192,852 (65%) patients had information recorded in the survey on incontinence status and were included in the analytical sample.

METHODS

Data from the 2018/2019 IPUP database were analyzed to evaluate the prevalence of incontinence (urinary [UI], fecal [FI], and dual [DI]), and the use of incontinence and moisture management strategies. Incontinence prevalence was analyzed between 3 groups of patients: (1) those without pressure injuries; (2) patients with stage 1 and 2 HAPIs; and (3) those with severe HAPIs (stage 3, 4, unstageable, deep tissue pressure injury). Analysis of the subgroups within acute care was also undertaken and included medical-surgical, critical care, and step-down units.

RESULTS

Incontinent patients were older (mean age 69-74 years depending on type of incontinence as compared to 62 years for continent patients) and had lower Braden Scale scores (range, 14.7-16.7, compared to 19.4 for continent patients). Half of the patients were female, 49.6% male, and 0.4% were unknown. Incontinence was identified in 32% of patients. Among patients with incontinence, 33% had UI, 12% had FI, and 55% had DI. Hospital-acquired pressure injuries were present in 27.4% of continent patients and 72.6% of incontinent patients, with DI having the highest rate of HAPIs. Analysis revealed a higher proportion of incontinent patients with unstageable HAPIs than continent patients (14.9% vs 9.6%, P = .00), as well as a higher proportion of incontinent patients with deep tissue HAPIs as compared to continent patients (27.0% vs 22.1%, P = .00). Significantly more incontinent patients regardless of HAPI status were using a bowel or bladder management system (P = .00).

CONCLUSION

Results of this study support the importance of incontinence as a risk factor in HAPI development. The prevalence of all types of incontinence was 31.7% for the entire sample. Almost three-fourths (72.6%) of patients with HAPI had UF, FI, or DI. A standardized definition of both UI and FI is needed, given that over 70% of all critical care unit patients with a urinary catheter for incontinence management were still classified as urinary incontinent.

Bacterial invasion into the epidermis of rats with sodium lauryl sulphate-irritated skin increases damage and induces incontinence-associated dermatitis

Incontinence-associated dermatitis (IAD) is caused by prolonged exposure to urine/liquid stool. It is a common and often painful skin condition in older incontinent adults because of poor prevention. Patients with urinary infections are at risk of developing IAD, and to guide the development of novel prevention strategies, we aimed to develop an animal model of IAD by urine and bacteria. First, contralateral sites on the dorsal skin of Sprague-Dawley rats were compromised by sodium lauryl sulphate (SLS), simulating frequent cleansing with soap/water. Filter discs were then placed inside ring-shaped chambers on foam dressings, inoculated with or without Pseudomonas aeruginosa, covered with agarose gels immersed in cultured filtrated urine, and secured in place with an occlusive dressing for 3 days. Untreated and SLS-compromised sites served as controls. The IAD was developed at bacteria-inoculated sites, characterised by severe IAD-like redness that persisted for up to 3 days post-exposure and higher disruption of the skin barrier function compared with non-inoculated sites. Pathological changes included epidermal thickening, partial skin loss, inflammatory cell infiltration, accumulation of red blood cells, and invasion of bacteria into the epidermis. This novel, clinically relevant IAD rat model can serve for future prevention developments.

The costs, health outcomes and cost-effectiveness of interventions for the prevention and treatment of incontinence-associated dermatitis: A systematic review

BACKGROUND

Incontinence-associated dermatitis is a common, under-recognized painful skin condition associated with poorer quality of life, increased nurse workloads, and costs.

OBJECTIVE

To systematically review economic evidence for the prevention and treatment of incontinence-associated dermatitis.

DESIGN

Systematic review of quantitative research.

DATA SOURCES

PubMed, MEDLINE, EMBASE, Cochrane Library, York Centre for Reviews and Dissemination database, Econlit, Tufts' Cost-Effectiveness Analysis Registry, and Web of Science.

REVIEW METHODS

A comprehensive search for studies on resource use (costs), health outcomes, and cost-effectiveness of interventions for incontinence-associated dermatitis was conducted. Screening, data extraction, and initial quality assessment were conducted independently by two reviewers, with disagreements/queries regarding quality settled through consensus with the larger team. Quality evaluated using the Consolidated Health Economic Evaluation Reporting Standards checklist and results narratively arranged.

FINDINGS

Seventeen studies (10 for prevention, one for treatment and six for both prevention and treatment) included. All studies measured resource use from a healthcare provider perspective; 14 quantified resources in monetary terms. Considerable variation existed in the resource use data primarily due to differences in the type of resources counted, selected time horizons, valuation methods, and reporting approaches. Ten studies provided evidence of their intervention to be cost saving (or at least cost avoiding). Five studies on barrier products provided evidence to be cost saving: three for prevention, one for treatment, and one for both prevention and treatment. Two studies of cleanser and barrier products provided evidence to be cost saving for the prevention and treatment of incontinence-associated dermatitis. One study found a cleanser to be a cost saving preventative intervention. One bowel management system was found to be cost saving over time only, and one nurse education intervention was found to be cost saving for preventing and treating incontinence-associated dermatitis. One barrier product was found to be cost-effective for preventing and treating the condition. Finally, one study found a cleanser and barrier product was time saving for prevention. None of the studies incorporated a multi-attribute quality of life measure; however, two studies included person-reported outcome measures for pain. A narrow range of resources (mainly products) were considered, and there was limited information on how they were counted and valued. Analyses relating to heterogeneity among patients/hospital wards or health facilities and uncertainty were lacking.

CONCLUSIONS

Barrier products are possibly a more cost-effective treatment than others; however, this evidence lacks certainty. Structured health economic evaluations are required for a reliable evidence-base on the interventions for incontinence-associated dermatitis.

TWEETABLE ABSTRACT

Most incontinence-associated dermatitis studies lack person-reported outcomes, costs beyond product/staff time, and economic evaluation.

Evaluating the Scales Used To Diagnose Incontinence-Associated Dermatitis: A Systematic Review

OBJECTIVE

To investigate the scales used in the diagnosis of incontinence-associated dermatitis (IAD), including the risk factors included in the scales, their reliability and validity, and in which patient groups the scales have been applied.

DATA SOURCES

The relevant studies were screened retrospectively using five MeSH (Medical Subject Headings) keywords in various combinations. Seven international databases were screened between March and July 2019. In total, 2,908 studies published between 2009 and 2019 were evaluated.

STUDY SELECTION

Inclusion criteria for studies were as follows: written in English, published between 2009 and 2019, and investigated a scale developed to diagnose IAD (quantitative studies, randomized controlled studies, or meta-analyses). Studies were excluded if they did not examine scales for diagnosing IAD or were not in English. Nine studies were included in this review: five studies on scale development, one scale revision, one scale reliability study, and two Turkish validity and reliability studies.

DATA EXTRACTION

The study methods, sample characteristics, interventions, validity and reliability analyses, risk factors in the scales, and subdimensions of the scales were examined for each of the nine included studies.

DATA SYNTHESIS

Study samples were composed of nurses, healthcare professionals, patients, or individuals living in a nursing home and ranged in size from 9 to 823 participants. Most data were collected from hospital-wide clinics. The scales used investigated redness, rash, skin loss, incontinence type, infection symptoms, skin color, edema, patient experience, pain, and perineal care habits. Both validity and reliability of the scales were examined in eight of the studies; in one study, only reliability was examined because the scale validity was shown in previous research. Moreover, sensitivity and specificity were indicated in one study.

CONCLUSIONS

There are several competent scales in the literature with proven validity and reliability that can be used to diagnose IAD.

Implementation of Pressure Injury Prevention Strategies in Acute Care: Results From the 2018-2019 International Pressure Injury Prevalence Survey

PURPOSE

The purpose of this study was to evaluate the implementation of pressure injury (PI) prevention strategies in adult acute care settings in the United States using the data from the 2018/2019 International Pressure Ulcer Prevalence (IPUP) Survey.

DESIGN

Observational, cohort study with cross-sectional data collection and retrospective data analysis.

SUBJECTS AND SETTING

The sample comprised 296,014 patients hospitalized in 1801 acute care facilities in the United States that participated in the 2018 and/or 2019 IPUP Survey. Slightly less than half (49.4%, n = 146,231) were male, 50% (n = 148,997) were female, 0.6% (n = 17,760) were unknown. Their mean age was 64.29 (SD 17.2) years.

METHODS

Data from the 2018/2019 IPUP database were analyzed to evaluate the implementation of prevention strategies including repositioning, support surface use, head-of-bed (HOB) elevation, heel elevation, moisture management, minimizing linen layers, and nutritional support. Practices were analyzed for differences between patients without pressure injuries, and patients with Stage 1 and 2 hospital-acquired pressure injury (HAPI), and those with severe HAPIs (Stage 3, Stage 4, unstageable, and deep tissue pressure injury). Acute care unit types included critical or intensive care units, medical-surgical inpatient care units, and step-down units.

RESULTS

Compliance rates to PI prevention strategies varied among patients at risk for HAPIs (Braden Scale for Pressure Sore Risk score ≤18). Daily skin assessment was performed for 86% of patients with no HAPIs and 96.8% of patients with severe HAPIs. Pressure redistribution was used in 74.6% of all patients and in over 90% of patients with severe HAPIs; however, compliance to routine repositioning was reported at lower levels between 67% and 84%, respectively. Heel elevation was reported for over 60% of the patients with severe HAPIs while 31.9% did not receive heel elevation, though only 6% were reported as not needing elevation. The majority of patients had HOB greater than the 30° at the time of the data collection; compliance with minimizing linen layers (≤3) was reported in 76% or more. Moisture management strategies were reportedly used in more than 71% of all patients and 89% for patients with severe HAPIs. Nutrition support was used for 55% to 82% of the patients and only documented as contraindicated in fewer than 2% of all groups.

CONCLUSION

Study findings revealed substantial compliance rates to PI prevention strategies. Nevertheless, there is potential for improvement in the implementation of some of the most basic prevention strategies including repositioning, heel elevation, nutritional support, and moisture management.

Moisture-Associated Skin Damage: Expanding and Updating Practice Based on the Newest ICD-10-CM Codes

Moisture-associated skin damage (MASD) occurs when skin is repeatedly exposed to various sources of bodily secretions or effluents, often leading to irritant contact dermatitis with inflammation, with or without denudation of affected skin. In 2020, the Wound, Ostomy and Continence Nurses Society took an initiative that led to the addition of multiple International Classification for Diseases codes for irritant contract dermatitis caused by various forms of MASD for use in the United States (ICD-10-CM). In the last issue of the Journal of Wound, Ostomy and Continence Nursing, a clinical practice alert identifying the various new codes was published that summarized each of the new codes and provided highlights of the descriptions of each of the these codes. This is the first in a series of 2 articles providing a more detailed description of the newest irritant contact dermatitis codes linked to MASD. Specifically, this article reviews the clinical manifestations and assessment, pathophysiology, epidemiology, prevention, and management of irritant contact dermatitis due to saliva, respiratory secretions, and fecal or urinary incontinence.

Clinician Knowledge of Incontinence-Associated Dermatitis: A Multisite Survey of Healthcare Professionals in Acute and Subacute Settings

PURPOSE

This study examined clinicians' knowledge of incontinence-associated dermatitis (IAD) using the Barakat-Johnson Incontinence-Associated Dermatitis Knowledge Tool (Know-IAD).

DESIGN

A cross-sectional multicenter survey.

SUBJECTS AND SETTING

The setting was 6 hospitals across 5 health districts in New South Wales, Australia. The participants were nurses (registered nurses and enrolled nurses), physicians, allied health (occupational therapists, dietitians, and physiotherapists), and students (nursing and allied health).

METHODS

Data about IAD knowledge were collected from November 2019 to January 2020. The Know-IAD, an 18-item validated instrument that measures knowledge of IAD in 3 domains (etiology and risk, classification and diagnosis, and prevention and management), was administered to a cross section of eligible clinicians. The participants anonymously completed hard copy surveys. Descriptive and exploratory analyses were conducted to quantify clinicians' knowledge about the etiology and risk, classification and diagnosis, and prevention and management of IAD. A mean knowledge score of 70% was considered to be satisfactory.

RESULTS

Four hundred twelve respondents completed the survey. One hundred twenty nine respondents (31.3%) achieved 70% correct responses and greater for the entire set of items. For the etiology and risk domain, 348 respondents (84.5%) obtained a score of 70% correct responses and greater, 67 respondents (16.3%) achieved 70% correct responses and greater for the classification and diagnosis domain, and 84 respondents (20.4%) achieved 70% correct responses and greater for the prevention and management domain.

CONCLUSION

Clinicians tend to have low knowledge and recognition of IAD, particularly in the areas of classification and diagnosis along with prevention and management. They tend to have higher knowledge of how IAD is caused and the risk factors. This study has identified knowledge gaps for further education that can improve assessment, prevention, and management of IAD.

Incidence and prevalence of pressure injuries in children patients: A systematic review and meta-analysis

BACKGROUND

Pressure injuries presently has been a serious healthcare problem all over the world. Children were recognized as the high-risk population of pressure injuries in the latest prevention and treatment of pressure injuries clinical practice guideline. However, the estimates of incidence, and prevalence of pressure injuries in hospitalized children patients vary considerable in relevant published studies.

OBJECTIVE

To systematically quantify the incidence and prevalence of pressure injuries (PIs) in hospitalized children and the most affected PIs sites.

METHODS

A systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. Electronic databases searches of the Cochrane Library, Pubmed, Web of Science, Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, China Knowledge Resource Integrated Database (CNKI), Wanfang Database, Chinese Biomedical Database (CBM), and Weipu Database (VIP), and hand-search through references were conducted to find relevant articles. Studies were evaluated independently by two researchers and audited by a third researcher. The data were extracted and presented in tables. The risk of bias was assessed using Hoy's tool. The I² statistic and random-effects model were used to assess the heterogeneity. Meta-regression analysis and subgroup analysis were conducted to examine between-study heterogeneity.

RESULTS

A total of 6, 672 articles were screened, and 30 studies with 251, 501 participants were ultimately included in this review. The pooled incidence of PIs for 3, 205 children was 13.5% (95% CI: 10.5-16.5); and the pooled prevalence of PIs for 4, 639 children was 12.2% (95% CI: 8.0-16.3). The most affected body sites were occiput, ears, and nose. Meta-regression and subgroup analysis showed that the inpatient ward, and region were the sources of heterogeneity.

CONCLUSIONS

The incidence and prevalence of PIs was significantly higher than the adults. Our discoveries recommended that healthcare givers ought to pay more consideration to diminish the happens of PIs. Additionally, more research may be needed to improve our understanding of the characteristics of PIs among children and to identify PIs risk factors to prevent and treat it in children effectively.

An exploratory study of the effects of the pH of synthetic urine on skin integrity in healthy participants

Background: Incontinence-associated dermatitis (IAD) develops from prolonged exposure of skin to urine and/or stool and represents a common complication in older adults, reducing the quality of life. Increased pH is an important etiologic factor of IAD, however, the relationship between urinary pH and skin barrier disruption remains unclear. Objective: To examine the effects of synthetic urine (s-urine) at various pH on transepidermal water loss (TEWL), stratum corneum hydration (SCH) and skin surface pH. Methods: S-urine solutions (pH 5.0-9.0) were applied to the volar forearms of 15 healthy participants for 2 hrs, with another site serving as the untreated control. Measurements of TEWL, SCH and skin surface pH were obtained at baseline and after each challenge. Skin buffering capacity was also examined in 5 volunteers by recording skin pH at baseline, after 2 hrs exposure and every 5 mins for 40 mins. Results: TEWL and SCH were increased following exposure to s-urine compared to baseline values. Although there was tendency for pH to an increase after exposure, further investigation showed that changes are only temporal as pH value is restored to baseline within 5 mins. There were no significant differences between solutions. Conclusions: This study revealed that urine disrupts healthy skin integrity; however, its effects are not pH dependent. Transient changes were observed on the acid mantle of the skin due to its innate buffering capacity. Future studies need to examine the effects of urine combined with bacteria responsible for pH elevation in patients with urinary incontinence.

Fecal diversion does not support healing of anus-near pressure ulcers in patients with spinal cord injury-results of a retrospective cohort study

STUDY DESIGN

Retrospective cohort study including spinal cord injured patients with anus-near pressure ulcers.

OBJECTIVE

The primary objective was to evaluate the impact of stool diversion via stoma on the decubital wound healing. Secondary objectives included the risk of complications and ulcer recurrence. Associations between the wound healing and potentially interfering parameters were determined.

SETTING

University hospital with a spinal cord injury unit.

METHODS

A total of 463 consecutive patients who presented with a decubitus were retrospectively included. Patients with and without a stoma were compared using descriptive and explorative statistics including multiple regression analysis.

RESULTS

The severity of the pressure ulcers was determined as stage 3 in two-thirds and stage 4 in one-third of all cases. The wound healing lasted longer in the 71 stoma-presenting patients than in the 392 patients with undeviated defecation (77 vs. 59 days, p = 0.02). The age (regression coefficient b = 0.41, p = 0.02), the ASA classification (b = 16.04, p = 0.001) and the stage of the ulcers (b = 19.65, p = 0.001) were associated with prolonged ulcer treatment in the univariate analysis. The multiple regression analysis revealed that the fecal diversion (b = -18.19, p = 0.03) and the stage of the ulcers (b = 21.62, p = 0.001) were the only predictors of delayed wound healing.

CONCLUSION

The presence of a stoma is not related to improved wound healing of ulcers near the anus. On the contrary, stoma patients needed more time until complete wound healing, conceivably related to selection bias. Nonetheless, we currently do not recommend fecal diversion to be the standard concept for decubitus treatment.

Development and Psychometric Testing of a Knowledge Instrument on Incontinence-Associated Dermatitis for Clinicians: The Know-IAD

PURPOSE

The purpose of this study was to describe the development and evaluation of the psychometric properties of an instrument used to assess clinician knowledge of Incontinence-associated dermatitis (IAD).

DESIGN

The instrument was developed in three phases: Phase 1 involved item development; Phase 2 evaluated content validity of the instrument by surveying clinicians and stakeholders within a single state of Australia and, Phase 3 used a pilot multisite cross-sectional survey design to determine composite reliability and evaluate scores of the knowledge tool.

SUBJECTS AND SETTINGS

In Phase 1, the instrument was developed by five persons with clinical and research subject expertise in the area of IAD. In Phase 2, content validity was evaluated by a group of 13 clinicians (nurses, physicians, occupational therapists, dietitians, and physiotherapists) working in acute care across one Australian state, New South Wales, along with two consumer representatives. In Phase 3, clinicians, working across six hospitals in New South Wales and on wards with patients diagnosed with incontinence-associated dermatitis, participated in pilot-testing the instrument.

METHODS

During Phase 1, a group of local and international experts developed items for a draft tool based on an international consensus document, our prior research evaluating incontinence-associated dermatitis knowledge, and agreement among an expert panel of clinicians and researchers. Phase 2 used a survey design to determine content validity of the knowledge tool. Specifically, we calculated item- and scale-level content validity ratios and content validity indices for all questions within the draft instrument. Phase 3 comprised pilot-testing of the knowledge tool using a cross-sectional survey. Analysis involved confirmatory factor analysis to confirm the hypothesized model structure of the knowledge tool, as measured by model goodness-of-fit. Composite reliability testing was undertaken to determine the extent of internal consistency between constituent items of each construct.

RESULTS

During Phase 1, a draft version of the Barakat-Johnson Incontinence-Associated Dermatitis Knowledge tool (Know-IAD), comprising 19 items and divided into three domains of IAD-related knowledge: 1) Etiology and Risk, 2) Classification and Diagnosis, and 3) Prevention and Management was developed. In Phase 2, 18 of the 19 items demonstrated high scale content validity ratios scores on relevance (0.75) and clarity (0.82); and high scale-content validity indices scores on relevance (0.87) and clarity (0.91). In Phase 3, the final 18-item Know-IAD tool demonstrated construct validity by a model goodness-of-fit. Construct validity was excellent for the Etiology and Risk domain (root mean squared error=0.02) and Prevention and Management domain (root mean squared error=0.02); it was good for the Classification and Diagnosis domain (root mean squared error=0.04). Composite reliability (CR) was good in the Etiology and Risk domain (CR=0.76), Prevention and Management domains (CR=0.75), and adequate in the Classification and Diagnosis domain (CR=0.64). Respondents had good understanding of etiology and risk (72.6% correct responses); fairly good understanding of prevention and management of IAD (64.0% correct responses) and moderate understanding of classification and diagnosis (40.2% correct responses).

CONCLUSIONS

The Know-IAD demonstrated good psychometric properties and provides preliminary evidence that it can be applied to evaluate clinician knowledge on IAD.

Prevention and Care for Incontinence-Associated Dermatitis Among Older Adults: A Systematic Review

Background

The prevalent rate of incontinence-associated dermatitis (IAD) trends upward in older populations. Skin breakdown from IAD impacts the quality of life of older adults and reflects the quality of care in hospitals and long-term care facilities. Specific and appropriate interventions for prevention and care are needed. This systematic review aims to review optimal strategies for prevention and care for older adults with IAD.

Methods

PubMed, CINAHL, SCOPUS, Medline, ProQuest, ThaiLIS, ThaiJo, and E-Thesis were searched for articles published between January 2010 and December 2020. Only articles focusing on older adults were included for the review.

Results

Eleven articles met the inclusion/exclusion criteria. Interventions for the prevention and care of IAD among older adults were categorized as assessment, incontinence management/causative factors management, cleansing, application of medical products for both skin moisturizing and skin barrier, body positioning, nutrition promotion, health education and training, and outcome evaluation. Specific prevention and care strategies for older adults with IAD included using specific assessment tools, applying skin cleansing pH from 4.0 to 6.8, body positioning, and promoting food with high protein. Other strategies were similar to those reported for adult patients.

Conclusion

The systematic review extracted current and specific prevention and care strategies for IAD in older adults. The prevention and care strategies from this systematic review should be applied in clinical practice. However, more rigorous research methodology is recommended in future studies, especially in examining intervention outcomes. Nurses and other health professionals should be educated and trained to understand the causes of IAD in older adults and the specific prevention and care strategies for this population. Because older adults are prone to skin damage, and this type of skin breakdown differs from pressure ulcers, the tools for assessment and evaluation, and the strategies for prevention and care require special attention.

Incontinence and Incontinence-Associated Dermatitis in Acute Care: A Retrospective Analysis of Total Cost of Care and Patient Outcomes From the Premier Healthcare Database

PURPOSE

To evaluate the prevalence of incontinence and treatment of incontinence-associated dermatitis (IAD) and associations with outcomes including total cost of care, length of stay (LOS), 30-day readmission, sacral area pressure injuries present on admission and hospital acquired pressure injuries, and progression of all sacral area pressure injuries to a higher stage.

DESIGN

Retrospective analysis.

SUBJECTS AND SETTINGS

Data were retrieved from the Premier Healthcare Database and comprised more than 15 million unique adult patient admissions from 937 hospitals. Patients were 18 years or older and admitted to a participating hospital between January 1, 2016, and December 31, 2019.

METHODS

Given the absence of an IAD International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code, we categorized patients treated for IAD by selecting patients with a documented incontinence ICD-10-CM code and a documented charge for dermatology products used to treat IAD. The t test and χ2 tests determined whether incontinence and treatment for IAD were associated with outcomes.

RESULTS

Incontinence prevalence was 1.5% for the entire sample; prevalence rate for IAD among incontinent patients was 0.7%. As compared to continent patients, incontinent patients had longer LOS (6.4 days versus 4.4 days), were 1.4 times more likely to be readmitted, 4.7 times more likely to have a sacral pressure injury upon admission pressure injury, 5.1 times more likely to have a sacral hospital-acquired pressure injury, and 5.8 times more likely to have a sacral pressure injury progress to a severe stage. As compared to incontinent patients without IAD treatment, those with IAD treatment had longer LOS (9.7 days versus 6.4 days), were 1.3 times more likely to be readmitted, and were 2.0 times more likely to have a sacral hospital-acquired pressure injury. Total index hospital costs were 1.2 times higher for incontinent patients and 1.3 times higher for patients with IAD treatment.

CONCLUSIONS

Incontinence and IAD prevalence are substantially lower than past research due to underreporting of incontinence. The lack of an ICD-10-CM code for IAD further exacerbates the underreporting of IAD. Despite low prevalence numbers, our results show higher health care costs and worse outcomes for incontinent patients and patients with IAD treatment.

A Qualitative Study on the Experience and Training Needs of ICU Nurses for Incontinence-Associated Dermatitis

OBJECTIVE

To explore the experience of incontinence-associated dermatitis (IAD) as perceived by nurses, obstacles in the nursing process, and need for IAD training and management.

METHODS

This single-setting descriptive qualitative study was conducted from June 5, 2018, to June 22, 2018. Ten nurses working in the respiratory ICU of a local hospital participated in semistructured interviews. The content analysis method was used to analyze, summarize, and refine the interview data.

RESULTS

The experience of ICU nurses with IAD can be divided into four types: nursing based on experiential knowledge, seeking self-improvement, disunity of cleaning methods and wiping skills, and postponement of nursing care because of priority allocation. Obstacles in the nursing process include a lack of relevant nursing knowledge and awareness, as well as the medical supplies needed. The goals of training and management include establishing IAD preventive nursing procedures, providing IAD care products, enhancing the practicality of training content and diversifying training methods, and establishing an information system to assist nurses caring for patients with IAD.

CONCLUSIONS

The knowledge and behavior of ICU nurses regarding IAD need to be improved. Training and management are imperative. Facilities and nurse managers should actively seek solutions to stated obstacles, formulate training methods suitable for clinical needs, and promote the standardization of nursing for IAD.

Conceptual Framework for Incontinence-Associated Dermatitis Based on Scoping Review and Expert Consensus Process

Incontinence-associated dermatitis (IAD) has been studied over the last decades, but gaps in the knowledge related to its identification, etiological agents, and risk factors remain. We carried out a scoping review about IAD that included systematic reviews, experimental, and observational studies about IAD and its potential risk factors. We retrieved 24 articles that described 100 potential risk factors and which were synthesized by the authors and proposed to a panel of experts. Panelists used a structured process of consensus development to create a conceptual framework of factors associated with IAD. This framework proposes that liquid fecal material, when combined with exposure to urine and stool, and bacterial contaminated urine are etiological factors for development of IAD. The framework also proposes 2 pathophysiological mechanisms and 8 main risk factors for IAD development. The proposed model could improve the quality of care for patients with or at risk of IAD, assisting healthcare professionals to identify at-risk patients, diagnose the type of lesion, and establish adequate and effective prevention and treatment measures.

Investigating the release of inflammatory cytokines in a human model of incontinence-associated dermatitis

Incontinence-associated dermatitis (IAD) is a painful complication in elderly patients, leading to reduced quality of life. Despite recent attention, its underlying inflammatory mechanisms remain poorly understood. This study was designed to quantify the release of inflammatory cytokines in a human model of IAD. The left volar forearm of ten healthy volunteers was exposed to synthetic urine and synthetic faeces for 2 h, simulating the effects of urinary and faecal incontinence, respectively, and the subsequent cytokine response compared to that of an untreated control site. Inflammatory cytokines were collected using both the Sebutape® absorption method and dermal microdialysis and quantified using immunoassays. Results from the former demonstrated an upregulation in IL-1α, IL-1RA and TNF-α. Synthetic urine caused a higher median increase in IL-1α from baseline compared to synthetic faeces, whereas synthetic faeces were associated with significantly higher median TNF-α levels compared to synthetic urine (p = 0.01). An increase in IL-1α/IL-1RA ratio was also observed with significant differences evident following exposure to synthetic urine (p = 0.047). Additionally, microdialysis revealed a time-dependent increase in IL-1β and IL-8 following exposure of up to 120 min to synthetic urine and synthetic faeces, respectively. This study demonstrated the suitability of both sampling approaches to recover quantifiable cytokine levels in biofluids for the assessment of skin status following exposure to synthetic fluids associated with incontinence. Findings suggest some differences in the inflammatory mechanisms of IAD, depending on moisture source, and the potential of the cytokines, IL-1α and TNF-α, as responsive markers of early skin damage caused by incontinence.
