Factors predicting the development of pressure ulcers in an at-risk population who receive standardized preventive care: secondary analyses of a multicentre randomised controlled trial

Investigation of related factors of operating room nurses' attitudes and awareness towards surgery-related pressure injury prevention in Turkey, Croatia, and Italy

OBJECTIVE

The aim of this study is to examine related factors of operating room nurses' attitudes and awareness towards surgery-related pressure injury prevention in Turkey, Croatia, and Italy.

METHODS

A descriptive and cross-sectional design was used. The study was conducted between March and September 2023. Data were collected with an online questionnaire created on Google Forms, consisting of a Nurse Information Form, a Surgery-related Pressure Injury Awareness Form, and the Attitude towards Pressure Ulcer Prevention Instrument.

RESULTS

The sample of the study consisted of 258 operating room nurses working in Turkey, Croatia, and Italy. It was found that the majority of the participants (70.90 %) did not use a risk scale, had not received education on pressure injury prevention and treatment (58.10 %) but wanted to receive it (86 %). Mean attitude scores of operating room nurses by country were at an adequate level in Turkey (42.48 ± 4.30) but not at the desired level in Croatia (37.48 ± 3.44) and Italy (36.20 ± 4.02). While there was a significant positive relationship between the awareness and attitudes of operating room nurses in Turkey (p = 0.002) and Croatia (p < 0.001), no relationship was found between these variables of nurses in Italy (p = 0.109). A statistically significant difference was found between nurses' consideration of themselves sufficient and their attitudes and awareness in all three countries (p < 0.05). It was also determined that reading articles affected nurses' awareness in all countries.

CONCLUSIONS

While operating room nurses' attitudes towards preventing pressure injuries were adequate in Turkey, it was determined that those of the nurses in Croatia and Italy were not at the desired level. Nurses should receive regular training on surgical pressure injuries to increase their awareness and to support them in implementing the recommendations of pressure injury guidelines in accordance with institutional policy.

Selective detection of urease-producing bacteria on the genital skin surface in patients with incontinence-associated dermatitis

We aimed to investigate the association between the presence of cutaneous urease-producing bacteria and the development of incontinence-associated dermatitis (IAD) using an original urea agar medium as a step toward developing advanced preventive measures. In previous clinical assessments, we developed an original urea agar medium to detect urease-producing bacteria via the medium's colour changes. In a cross-sectional study, specimens were collected via the swabbing technique at genital skin sites in 52 stroke patients hospitalised in a university hospital. The primary objective was to compare the presence of urease-producing bacteria between the IAD and no-IAD groups. Determining the bacterial count was the secondary objective. The prevalence of IAD was 48%. A significantly higher detection rate of urease-producing bacteria was observed in the IAD group than in the no-IAD group (P = .002) despite the total number of bacteria being equivalent between them. In conclusion, we discovered that there was a significant association between the presence of urease-producing bacteria and IAD development in hospitalised stroke patients.

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.

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 Science of Skin: Measuring Damage and Assessing Risk

Significance: Healthy skin provides a barrier to contaminants. Breaches in skin integrity are often encountered in the patient health care journey, owing to intrinsic health issues or to various procedures and medical devices used. The time has come to move clinical practice beyond mere awareness of medical adhesive-related skin injury and toward improved care and outcomes. Recent Advances: Methods developed in research settings allow quantitative assessments of skin damage based on the measurement of baseline skin properties. These properties become altered by stress and over time. Assessment methods typically used by the cosmetic industry to compare product performance could offer new possibilities to improve clinical practice by providing better information on the status of patient skin. This review summarizes available skin assessment methods as well as specific patient risks for skin damage. Critical Issues: Patients in health care settings may be at risk for skin damage owing to predisposing medical conditions, health status, medications taken, and procedures or devices used in their treatment. Skin injuries come as an additional burden to these medical circumstances and could be prevented. Technology should be leveraged to improve care, help maintain patient skin health, and better characterize functional wound closure. Future Directions: Skin testing methods developed to evaluate cosmetic products or assess damage caused by occupational exposure can provide detailed, quantitative information on the integrity of skin. Such methods have the potential to guide prevention and treatment efforts to improve the care of patients suffering from skin integrity issues while in the health care system.

Biomedical materials for wound dressing: recent advances and applications

Wound healing is vital to maintain the physiological functions of the skin. The most common treatment is the use of a dressing to cover the wound and reduce infection risk and the rate of secondary injuries. Modern wound dressings have been the top priority choice for healing various types of wounds owing to their outstanding biocompatibility and biodegradability. In addition, they also maintain temperature and a moist environment, aid in pain relief, and improve hypoxic environments to stimulate wound healing. Due to the different types of wounds, as well as the variety of advanced wound dressing products, this review will provide information on the clinical characteristics of the wound, the properties of common modern dressings, and the in vitro, in vivo as well as the clinical trials on their effectiveness. The most popular types commonly used in producing modern dressings are hydrogels, hydrocolloids, alginates, foams, and films. In addition, the review also presents the polymer materials for dressing applications as well as the trend of developing these current modern dressings to maximize their function and create ideal dressings. The last is the discussion about dressing selection in wound treatment and an estimate of the current development tendency of new materials for wound healing dressings.

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.

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.

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.

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.

Neonatal Intensive Care Nursing Pressure Injury Prevention Practices: A Descriptive Survey

PURPOSE

The purpose of this study was to explore neonatal nursing practices for neonatal pressure injury (PI) risk assessment, pressure redistribution surface use, and moisture management.

DESIGN

A descriptive survey.

SUBJECT/SETTINGS

A sample of 252 neonatal nurses mainly from the United States responded to a survey distributed electronically through the National Association of Neonatal Nurses, the Academy of Neonatal Nurses, and on the Wound Source Web site.

METHODS

Nurses responded to questions that explored what neonatal nurses used to assess PI risk, types of pressure redistribution surfaces used for neonates, and what moisture management strategies were used to prevent PIs. Descriptive statistics were used to describe nurses' practices.

RESULTS

When assessing risk, 78% (n = 197/252) reported using a risk assessment scale: the 2 most common scales were the Neonatal Skin Risk Assessment Scale and the Braden Q Scale. Sixty-nine percent (n = 174/252) reported using a rolled blanket or small soft object as pressure redistribution surfaces. In addition, 15% (n = 39) reported the use of different types of positioners such as a fluidized positioner as pressure redistribution surfaces; however, these are marketed as a positioning devices. It appears that these interventions were considered redistribution surfaces by the nurses. For moisture management, petrolatum-based products (6.7%; n = 17/252) and ostomy powders (6%; n = 16/252) were most frequently used.

CONCLUSIONS

Practices for PI prevention are different for neonatal patients due to their gestational age, size, and level of illness. Findings from this study create a beginning knowledge of and an opportunity for further research to determine how these practices affect outcomes such as PI incidence and prevalence.

A model for predicting 7-day pressure injury outcomes in paediatric patients: A machine learning approach

AIMS

We sought to explore factors associated with early pressure injury progression and build a model for predicting these outcomes using a machine learning approach.

DESIGN

A retrospective cohort study.

METHODS

In this study, we recruited paediatric patients, with hospital-acquired stage I pressure injury or suspected deep tissue injury, who met the inclusion criteria between 1 January 2015-31 October 2018. We divided patients into two groups, namely healing or delayed healing, then followed them up for 7 days. We analysed patient pressure injury characteristics, demographics, treatment, clinical situation, vital signs, and blood test results, then build prediction models using the Random Forest and eXtreme Gradient Boosting approaches.

RESULTS

The best prediction model, trained and tested using Random Forest with 10 variables, achieved an accuracy, sensitivity, specificity, and area under the curve of 0.82 (SD 0.06), 0.80 (SD 0.08), 0.84 (SD 0.08), and 0.89 (SD 0.06), respectively. The most contributing variables, in order of importance, included serum creatinine, red blood cell, and haematocrit.

CONCLUSION

An awareness of specific conditions and areas that could lead to delayed healing pressure injury in paediatric patients is needed.

IMPACT

This evidence-based prediction model, coupled with the aforementioned clinical indicators, is expected to enhance early prediction of outcomes in paediatric patients thereby improve the quality of care and the outcome of children with PIs.

Prevalence, incidence and risk factors for foot pressure ulcers in hospitalized elderly patients. An observational and prospective study

BACKGROUND

Incidence and clinical characteristics of foot pressure ulcers (FPU) in hospitalized elderly patients are not well known. The aim of the study was to determine the incidence of FPU during hospitalization, to describe main FPU characteristics and to assess main risk factors for FPU in hospitalised elderly subjects.

METHODOLOGY

An observational prospective study was performed in which patients 65 years or older admitted to Vascular Surgery, Orthopaedic or Geriatric departments were followed from admission to discharge. Trained nurses evaluated all recruited patients on a daily basis for possible FPU. Main characteristics of the patient (age, sex and co-morbidities) and the ulcer (location, grade) were registered.

RESULTS

299 patients were recruited (62.2% women, mean age 82.3 years, mean number of co-morbidities 2.8). Prevalence of FPU was 30.1% at admission and 73.9% at discharge. Incidence of FPU during hospitalization was 9.5 new FPU/100 person-day. 97.0% of the new FPU were grade 1 (erythema) and the most common locations were in the heel (57.6%), the external lateral part of the foot (13.1%), and the hallux of the fist toe (11.8%). Apart from immobility, main risk factors for FPU are age, geriatric residence origin and not able to outdoor life.

CONCLUSIONS

FPU has a high incidence among hospitalised elderly patients; most of them are grade 1 and located in the heel. More attention must be paid in the prevention of pressure ulcers in hospitalized frail subjects.

Pressure Ulcer Risk Factors in Persons with Mobility-Related Disabilities

OBJECTIVE

To assess pressure ulcer (PU) risk in persons with mobility impairments using a large data set to identify demographic, laboratory, hemodynamic, and pharmacologic risk factors.

METHODS

The cohort of interest was persons with disabilities who have mobility impairments and are diagnostically at risk of PUs. To define this cohort, diagnoses that qualify patients for skin protection wheelchair cushions were used. Data were obtained from the Cerner Health Facts data warehouse. Two cohorts were defined: persons with and without a history of PUs. Analysis included descriptive statistics and multivariate logistic regression modeling. Variables retained in the model were identified using LASSO, gradient boosting, and Bayesian model averaging.

MAIN RESULTS

The resulting cohorts included more than 87,000 persons with a history of PUs and more than 1.1 million persons who did not have a PU. The data revealed seven disability groups with the greatest prevalence of PUs: those with Alzheimer disease, cerebral palsy, hemiplegia, multiple sclerosis, paraplegia/quadriplegia, Parkinson disease, and spina bifida. Ulcers in the pelvic region accounted for 82% of PUs. Persons with disabilities who were male or black had a greater prevalence of PUs. Physiologic risk factors included the presence of kidney or renal disease, decreased serum albumin, and increased serum C-reactive protein.

CONCLUSIONS

The results indicate that, although persons with disabilities can exhibit a wide functional range, they remain at risk of PUs and should be evaluated for proper preventive measures, including support surfaces and wheelchair cushions.

Best Practice in Pressure Injury Prevention Among Critical Care Patients

Pressure injuries are areas of damage to the skin and underlying tissue caused by pressure or pressure in combination with shear. Pressure injury prevention in the critical care population necessitates risk assessment, selection of appropriate preventive interventions, and ongoing assessment to determine the adequacy of the preventive interventions. Best practices in preventive interventions among critical care patients, including skin and tissue assessment, skin care, repositioning, nutrition, support surfaces, and early mobilization, are described. Unique considerations in special populations including older adults and individuals with obesity are also addressed.

The Prevalence of Incontinence-Associated Dermatitis in Hospitalized Patients in China: A Systematic Review and Meta-Analysis

OBJECTIVE

To determine the prevalence and characteristics of incontinence-associated dermatitis (IAD) among hospitalized Chinese patients.

DATA SOURCES

Authors searched Chinese (China National Knowledge Infrastructure, Wanfang Data, VIP Data, Chinese Biomedicine) and English (PubMed, Web of Science) electronic databases for articles published from 1987 through February 2019.

STUDY SELECTION

The preliminary search identified 558 studies. After removal of duplicates (n = 202), application of exclusion criteria, and screening titles and abstracts (n = 346), 10 studies met the inclusion criteria.

DATA EXTRACTION

A standardized form was constructed to extract data from eligible studies, and this information was extracted by two independent authors.

DATA SYNTHESIS

A pooled analysis of the 10 studies (total sample size, 40,039) showed the prevalence of IAD in hospitalized Chinese patients was 1.44% (95% confidence interval, 1.10%-1.79%). Subgroup analysis indicated no significant association between sex and IAD. Patients older than 90 years had the highest incidence of IAD (8.64%). The most common type was mild IAD (1.00%). Fecal incontinence (48.02%) led to more cases of IAD than urinary incontinence (11.35%) or both (25.78%). The most common types of IAD were perineal (0.92%) and perianal (0.90%).

CONCLUSIONS

Incontinence-associated dermatitis is a global health problem that requires more attention. Understanding the prevalence and characteristics of IAD is helpful in the formulation of IAD prevention and treatment programs in China.

The prevalence and prevention of pressure ulcers: A multicenter study of nine nursing homes in eastern China

AIM

To assess the prevalence, related factors, and strategies for the prevention and treatment of pressure ulcers (PUs) in nursing homes in eastern China.

MATERIALS AND METHODS

In this cross-sectional multicenter survey, assessments of 1158 residents in nine nursing homes in eastern China were conducted on a single day in August of 2019.

RESULTS

Of the 1158 residents, 56 (4.8%) had at least one PU. Most of the identified PUs were classified as stage 3 (39.3%) and developed at home (55.4%). By multiple regression analysis, eating mode, bed-bound, and Braden score were significant association with the development of PUs in nursing homes.

CONCLUSIONS

The prevalence of PUs in this study was similar to that reported by previous international studies. The implementation of measures for the prevention and treatment of PUs is insufficient in nursing homes in eastern China. Further, this study raised the issue of the lack of measures to prevent the development of PUs at home.

Selection of Appropriate Wound Dressing for Various Wounds

There are many factors involved in wound healing, and the healing process is not static. The therapeutic effect of modern wound dressings in the clinical management of wounds is documented. However, there are few reports regarding the reasonable selection of dressings for certain types of wounds in the clinic. In this article, we retrospect the history of wound dressing development and the classification of modern wound dressings. In addition, the pros and cons of mainstream modern wound dressings for the healing of different wounds, such as diabetic foot ulcers, pressure ulcers, burns and scalds, and chronic leg ulcers, as well as the physiological mechanisms involved in wound healing are summarized. This article provides a clinical guideline for selecting suitable wound dressings according to the types of wounds.

Prevalence of pressure ulcers in hospitalised patients: a cross-sectional study

OBJECTIVE

The main aim of this study was to estimate the prevalence of pressure ulcers (PU) and related risk factors of PU development in hospitalised patients in Italy. Furthermore, the study investigated the association between risk factors for PU present on admission and the development during hospitalisation (hospital-acquired pressure ulcer, HAPU).

METHODS

A cross-sectional study, using two separate designs at two separate timepoints: 2010 and 2015. The methodology used to measure PU prevalence was that recommended by the European Pressure Ulcer Advisory Panel (EPUAP).

RESULTS

The total sample was 7681 hospitalised patients (3011 patients in 2010, 4670 in 2015). Prevalence of PU in hospital was 19.5% in 2010 and 17% in 2015. The number of patients with PU present on admission were 9.60% in 2010 and 9.42% in 2015. Patients with HAPU were 5.08% in 2010 and 5.87% in 2015. Older age and comorbidities, and a total Braden score of ≤16 were positively associated with PU present on admission and HAPU in hospitals (p<0.05). A longer length of stay appeared to correlate positively with a better clinical outcome for PU if there were already present on admission. Heterogeneous results emerged for length of stay of >30 days and being admitted to intensive care unit (ICU).

CONCLUSION

Our results are comparable with other European and Italian studies. Most of the risk factors associated with PU development have been confirmed. However, further studies are needed to examine the effects of context on PU present on arrival and HAPU, especially regarding hospital length of stay.

Postoperative pressure injuries in adults having surgery under general anaesthesia: systematic review of perioperative risk factors

BACKGROUND

Pressure injuries (PIs) after surgery affect thousands of people worldwide. Their management is expensive, a cost that can be reduced with proper preventive measures. Patients having surgery under general anaesthesia are at risk of developing PI, yet no specific tool has been developed to assess the risk in these patients. This review aimed to summarize the published data on perioperative risk factors associated with the development of PI in adults having surgery under general anaesthesia.

METHODS

All studies reporting on risk factors associated with the development of PI were included. Data were extracted from all articles and meta-analysis was performed when three or more studies reported on a specific variable.

RESULTS

The analysis identified five factors significantly associated with the development of PIs: cardiovascular disease, respiratory disease, diabetes mellitus, low haemoglobin level and longer duration of surgery. Factors not associated included serum albumin concentration, use of vasopressors during surgery, use of corticosteroids, sex and age.

CONCLUSION

Cardiovascular disease, respiratory disease, diabetes mellitus, anaemia and duration of surgery should be taken into consideration when trying to identify surgical patients at high risk of developing PIs. These factors could be used to predict PIs after surgery.

The pressure injury predictive model: A framework for hospital-acquired pressure injuries

BACKGROUND

Despite decades of research, pressure injuries continue to be a source of significant pain and delayed recovery for patients and substantial quality and cost issues for hospitals. Consideration of the current thinking around pressure injury risk must be evaluated to improve risk assessments and subsequent nursing interventions aimed at reducing hospital-acquired pressure injuries.

DESIGN

This is a discursive paper using Walker and Avant's (2005) theory synthesis framework to examine the relevance of existing pressure injury models as they align with the current literature.

METHODS

PubMed and CINAHL indexes were searched, first for conceptual models and then for pressure injury research conducted on hospitalised patients for the years 2006-2016. A synthesis of the searches culminated into a new pressure injury risk model.

CONCLUSIONS

Gaps in previous models include lack of attention to the environment, contributing episode-of-care factors and the dynamic nature of injury risk for patients. Through theory synthesis, the need for a new model representing the full risk for pressure injury was identified. The Pressure Injury Predictive Model is a representation of the complex and dynamic nature of pressure injury risk that builds on previous models and addresses new patient, contextual and episode-of-care process influences. The Pressure Injury Predictive Model (PIPM) provides a more accurate picture of the complexity of contextual and process factors associated with pressure injury development.

RELEVANCE TO CLINICAL PRACTICE

Using the PIPM to determine risk can result in improved risk identification. This information can be used to implement targeted, evidence-based pressure injury prevention interventions specific to the patient risk profile, thus limiting unwarranted and unnecessary care.

Examining Prevalence and Risk Factors of Incontinence-Associated Dermatitis Using the International Pressure Ulcer Prevalence Survey

PURPOSE:

To evaluate prevalence and risk factors of incontinence-associated dermatitis (IAD).

DESIGN:

Retrospective analysis of 2016 International Pressure Ulcer Prevalence survey data.

SUBJECTS AND SETTING:

Adult patients who were in acute care, long-term acute care, long-term care, and rehabilitation facilities in the United States and Canada.

METHODS:

IAD prevalence was calculated among all patients surveyed, among the incontinent patients only, across multiple care settings, and by incontinence type. A logistic regression examined risk factors for IAD in the incontinent population.

RESULTS:

Nearly 1 in 5 incontinent patients had IAD documented. Incontinence-associated dermatitis prevalence in the entire patient population was 4.3% while incontinence prevalence was 18%. Of incontinent patients, prevalence of IAD ranged from 8.4% in long-term care facilities to 19% in acute care facilities. Facilities with higher rates of incontinence did not necessarily have higher prevalence of IAD. Incontinence-associated dermatitis prevalence by incontinence type ranged from 12% for patients with urinary incontinence to 26% for patients with fecal management systems. Regression results support the association of the following factors with an increased likelihood of IAD documented: all types of incontinence, fecal management systems, higher body weight, diminished mobility, additional linen layers, longer length of stay, and lower Braden Scale scores.

CONCLUSIONS:

Incontinence-associated dermatitis remains a concern in acute care settings. Risk factors associated with IAD were similar to risk factors previously reported for hospital-acquired pressure injuries, such as limited mobility, longer lengths of stay, and additional linen layers. By consistently documenting IAD as well as pressure injury prevalence, facilities may benchmark overall skin prevention models.

Pressure ulcer prevalence and prevention rates in Abu Dhabi: an update

OBJECTIVE

This article compares the results from a recent pressure ulcer (PU) prevalence audit at the Sheikh Khalifa Medical City (SKMC) hospital in Abu Dhabi to identify the impact of new prevention initiatives introduced around 2013 and establish the effectiveness of PU prevention strategies, judged quality of nursing care, and costs associated with patients developing a hospital-acquired pressure ulcer (HAPU).

METHOD

The methods used were based on a previous point prevalence study involving 441 acute care patients, who were assessed using the International Pressure Ulcer Prevalence (IPUP) Survey. Following pre-selection of a 24-hour period for data capture, hospital staff collected PU data. Hill-Rom provided SKMC with an electronic report comprising various epidemiological and financial outputs.

RESULTS

PU prevalence was 10.4% in 2018 versus 6.4% in 2013. The 2018 HAPU prevalence was 1.8% versus 2% in 2013. The 2018 findings were in line with IPUP's international benchmarks. In 2018, 99% of patients had their skin assessed and PU risk documented within 24 hours of admission, leading to rapid implementation of a prevention care plan. Most patients who developed a HAPU (n=8) were female (62%) and aged 20-29 years old (25%) or 70-79 years old (25%). All HAPU patients lay on three layers of linen, most on their side (88%) and 75% were hospitalised for >30 days. Costs were estimated for the eight HAPU patients; weighted average cost (per case) was around US$8035.32, giving a total estimated cost of US$64,282.54. Total annual cost (average length of stay basis) for the eight patients was estimated at US$1,830,082.32.

CONCLUSION

The PU prevention plan at SKMC proved to be effective, reflected by a low HAPU prevalence rate, suggesting an excellent quality of patient care.

Modifiable patient-related factors associated with pressure ulcers on the sacrum and heels: Secondary data analyses

AIM

To explore factors associated with the presence of category I-IV pressure ulcers on the sacrum and heels.

DESIGN

Cross-sectional, secondary data analysis using data collected from the Landelijke Prevalentiemeting Zorgproblemen (LPZ) project, a multicentre prevalence study including nursing home residents and community care clients (N = 4,842) in the Netherlands in 2017.

METHODS

A single binary logistic regression model was designed to identify factors associated with the presence of pressure ulcers. Additionally, a multiple binary logistic regression model including modifiable explanatory factors associated with the presence of pressure ulcers was designed.

RESULTS

Impaired mobility, friction and shear (evaluated using the Braden Scale) are significantly associated with the presence of both sacral and heel category I-IV pressure ulcers. Incontinence-associated dermatitis is significantly associated with category I-IV sacral pressure ulcers.

CONCLUSION

In pressure ulcer prevention, nursing interventions should focus on frequent repositioning and mobilization while avoiding exposure of the skin to friction and shear. The need to consider incontinence-associated dermatitis, incontinence and moisture as important factors in pressure ulcer risk assessment is confirmed.

IMPACT

Pressure ulcers occur when skin and tissues are deformed between bony prominences and the support surface in a sitting or lying position. They are the result of a complex interaction between direct causal factors and a wide range of indirect factors. Recognition of these factors influences risk assessment guidance and practice. Knowledge of skin-specific factors at the patient level, modifiable by nursing interventions, enables a better targeted and tailored preventive approach.

How to manage incontinence-associated dermatitis in older adults

An estimated 14 million adults experience incontinence in England alone, and this population is at a very high risk of developing incontinence-associated dermatitis (IAD). The risk associated with developing IAD is further increased among older adults, due to the effects of the ageing process, which leave the skin thinner and more fragile. Understanding the causative factors of IAD in addition to understanding the impact of IAD on the skin enable the clinician to make informed choices regarding treatment, management and prevention. Additionally, understanding the association between IAD and pressure ulcers is a critical component of IAD management, as IAD and pressure ulcers often coexist or develop alongside each other.

Outcome measurement instruments for erythema associated with incontinence-associated dermatitis: Systematic review

AIM

To: (a) examine which outcome measurement instruments for erythema associated with incontinence-associated dermatitis (IAD) with supporting evidence about measurement properties are available; (b) evaluate the methodological quality of the studies and the quality of the measurement properties; and (c) identify eligible instruments to measure erythema in incontinence-associated dermatitis research.

DESIGN

Systematic review.

DATA SOURCES

MEDLINE, EMBASE, CINAHL and CENTRAL were systematically searched until July 2018 (update December 2018). Additional input was gathered from 151 incontinence-associated dermatitis experts. Cited and citing references of included studies were screened.

REVIEW METHODS

The COSMIN Risk of Bias checklist was applied to evaluate the methodological quality of the studies. Reported measurement properties were rated against criteria for good measurement properties.

RESULTS

Fourteen studies, describing 10 measurement instruments, were included. In five instruments, erythema was captured as a separate concept, two studies provided empirical evidence about the measurement properties. The most studied measurement properties were reliability (9 studies), measurement error (4 studies) and criterion validity (4 studies). In one study, internal consistency was examined.

CONCLUSION

No instrument measuring exclusively erythema associated with incontinence-associated dermatitis exists. There is no single composite incontinence-associated dermatitis measurement instrument that outperforms others. Development or adaption of an instrument to measure erythema associated with incontinence-associated dermatitis is one option to solve this challenge.

IMPACT

The evidence about measurement properties of instruments measuring erythema associated with incontinence-associated dermatitis has not been summarized to date. The lack of an instrument should trigger activities to measure this domain accurately in future clinical trials.

Independent risk factors for pressure ulcer development in a high-risk nursing home population receiving evidence-based pressure ulcer prevention: Results from a study in 26 nursing homes in Belgium

The aim of this study was to identify independent risk factors for pressure ulcer (PU) development in a high-risk nursing home population receiving evidence-based PU prevention. This study was part of a randomised controlled trial examining the (cost-)effectiveness of static air support surfaces compared with alternating pressure air mattresses. The sample consisted of 308 residents at a high risk of PU development (presence of non-blanchable erythema, Braden score ≤ 12 or Braden subscale "mobility" ≤ 2). PU incidence was monitored for 14 days. Demographic variables; functional, physical, and psychological characteristics; and data on skin assessment were collected. Independent risk factors were identified using multiple logistic regression analysis. The overall PU incidence (category II-IV) was 8.4% (n = 26), and 1.9% (n = 6) of the residents developed a deep PU (category III-IV). PUs (category II-IV) were significantly associated with non-blanchable erythema, a lower Braden score, and pressure area-related pain in high-risk residents even if preventive care was provided. These results highlight the need of a systematic risk assessment, including pain assessment and skin observations, in order to determine and tailor preventive care to the needs of high-risk individuals.

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

PURPOSE:

The purpose of this study was to measure the prevalence of incontinence-associated dermatitis (IAD) among incontinent persons in the acute care setting, characteristics of IAD in this group, and associations among IAD, urinary, fecal, and dual incontinence, immobility, and pressure injury in the sacral area.

DESIGN:

Descriptive and correlational analysis of data from a large database of IAD, and pressure injuries of sacral area and heels.

SUBJECTS AND SETTING:

The sample comprised 5342 adult patients in acute care facilities in 36 states representing all regions of the United States. Facilities used a variety of products for prevention of IAD and sacral area pressure injuries.

METHODS:

Data were collected for use in a national quality improvement study evaluating current practices related to the prevention of IAD and pressure injuries affecting the sacral area and heels. Data were exported to a spreadsheet, and triple checked for accuracy before being imported to a statistical analysis software program. Descriptive statistics were used to describe prevalence rates for incontinence, types of incontinence, IAD, characteristics of IAD, and pressure injuries. Multivariate logistic regression analysis was conducted on the end point of facility-acquired sacral/buttock pressure injury and the risk factors of immobility and type of incontinence.

RESULTS:

More than one-third of patients (n = 2492 of 5342 patients; 46.6%) were incontinent of urine, stool, or both. The overall prevalence rate of IAD was 21.3% (1140/5342); the prevalence of IAD among patients with incontinence was 45.7% (1140/2492). Slightly more than half of the IAD was categorized as mild (596/1140, 52.3%), 27.9% (318/1140) was categorized as moderate, and 9.2% (105/1140) was deemed severe. In addition, 14.8% (169/1140) of patients with IAD also had a fungal rash. The prevalence of pressure injury in the sacral area among individuals with incontinence was 17.1% (427/2492), and the prevalence of full-thickness pressure injury in this population was 3.8% (95/2492). Multivariate analysis revealed that both presence of IAD (odds ratio [OR], 4.56; 95% confidence interval [CI], 3.68-5.65) and immobility (OR, 3.56; 95% CI, 2.73-4.63) was associated with a significantly increased likelihood of developing a sacral pressure injury. Multivariate analysis also revealed that presence of IAD (OR, 2.65; 95% CI, 1.74-4.03) and immobility (OR, 6.05; 95% CI, 3.14-11.64) was associated with a significantly increased likelihood of developing full-thickness sacral pressure injury.

CONCLUSION:

Our study findings are consistent with prior research, supporting a clinically relevant association between IAD and pressure injury of the sacral area. This risk persists even after controlling for presence of immobility, suggesting that IAD functions as an independent risk factor for pressure injury occurrence.

Independent risk factors for the development of incontinence-associated dermatitis (category 2) in critically ill patients with fecal incontinence: A cross-sectional observational study in 48 ICU units

BACKGROUND

Critically ill patients suffering from fecal incontinence have a major risk of developing incontinence-associated dermatitis (IAD). The presence of moisture and digestive enzymes (lipase, protease) negatively influences skin barrier function. Additional risk factors will make some patients even more vulnerable than others. In order to provide (cost) effective prevention, this specific patient population should be identified timely.

OBJECTIVES

To identify independent risk factors for the development of IAD category 2 (skin loss) in critically ill patients with fecal incontinence.

DESIGN

A cross-sectional observational study.

SETTING AND PARTICIPANTS

The study was performed in 48 ICU wards from 27 Belgian hospitals. Patients of 18 years or older, with fecal incontinence at the moment of data collection, were eligible to participate. Patients with persistent skin redness due to incontinence (IAD category 1) were excluded.

METHODS

Potential risk factors were carefully determined based on literature and expert consultations. Data were collected over a period of eight months by trained researchers using patient records and observation of skin care practices. At the time a patient was included in the study, all relevant data from the past six days, or since admission at the ICU, were recorded. Simultaneously, direct skin observations were performed and high definition photographs were ratified by an expert IAD researcher. A multiple binary logistic regression model was composed to identify independent risk factors. Variables with P < .25 in single binary logistic regression analyses were added to the multiple model using a forward procedure. A cut-off value of P < .1 was established to retain variables in the final model. Nagelkerke's R² and Hosmer-Lemeshow statistic were calculated as measures of model fit.

RESULTS

The sample comprised of 206 patients, of which 95 presented with IAD category 2, and 111 were free of IAD. Seven independent risk factors were identified: liquid stool [odds ratio (OR) 4.69; 95% confidence interval (CI) 2.28-9.62], diabetes (OR 2.89; 95% CI 1.34-6.27), age (OR 1.05; 95% CI 1.02-1.08), smoking (OR 2.67; 95% CI 1.21-5.91), non-use of diapers (OR 2.97; 95% CI 1.39-6.33), fever (OR 2.60; 95% CI 1.23-5.53), and low oxygen saturation (OR 2.15; 95% CI 1.03-4.48). Nagelkerke's R² was 0.377. The Hosmer-Lemeshow statistic indicated no significant difference between the observed and expected values (p = .301).

CONCLUSIONS

Liquid stool, diabetes, age, smoking, non-use of diapers, fever, and low oxygen saturation were independently associated with IAD category 2 in critically ill patients with fecal incontinence.

The prevalence and specific characteristics of hospitalised pressure ulcer patients: A multicentre cross-sectional study

OBJECTIVE

To ascertain the pressure ulcer prevalence in secondary and tertiary general hospitals in different areas of Guangdong Province in China and explore the possible risk factors that are related to pressure ulcers.

BACKGROUND

Few multicentre studies have been conducted on pressure ulcer prevalence in Chinese hospitals.

DESIGN

A cross-sectional study design was used.

METHODS

Data from a total of 25,264 patients were included in the analysis at 25 hospitals in China. The investigators were divided into two groups. The investigators in group 1 examined the patients' skin. When a pressure ulcer was found, a pressure ulcer assessment form was completed. The investigators in group 2 provided guidance to the nurses, who assessed all patients and completed another questionnaire. A multivariate logistic regression analysis was used to analyse the relationship between the possible risk factors and pressure ulcer.

RESULTS

The overall prevalence rate of pressure ulcers in the 25 hospitals ranged from 0%-3.49%, with a mean of 1.26%. The most common stage of the pressure ulcers was stage II (41.4%); most common anatomical locations were sacrum (39.5%) and the feet (16.4%). Braden score (p < .001), expected length of stay (p < .001), incontinence (p < .001), care group (p = .011), hospital location (p < .001), type of hospitals (p = .004), ages of patients (p < .001) were associations of pressure ulcers from the multivariate logistic regression analysis.

CONCLUSIONS

The overall prevalence rate of pressure ulcers in Chinese hospitals was lower than that reported in previous investigations. Specific characteristics of pressure ulcer patients were as follows: low Braden score, longer expected length of stay, double incontinence, an ICU and a medical ward, hospital location in the Pearl River Delta, a university hospital and an older patient.

RELEVANCE TO CLINICAL PRACTICE

The survey could make managers know their prevalence level of pressure ulcers and provide priorities for clinical nurses.

Measuring the quality of pressure ulcer prevention: A systematic mapping review of quality indicators

The aim of this study was to provide a systematic overview of available pressure ulcer prevention quality indicators and to evaluate the underlying empirical evidence. A systematic mapping review was conducted with combined searches in Embase and Medline, and websites of relevant institutions and organisations. The eligibility criteria were clear use of the term "quality indicator" regarding pressure ulcer prevention; English or German language; and all settings, populations, and types of resources, including articles, brochures, and online material. In total, n = 146 quality indicators were identified. Most indicators were published in the United States (n = 50). The majority of indicators was developed for the hospital setting (n = 102). Process indicators were the most common (n = 71), followed by outcome indicators (n = 49). Less than half of identified indicators appeared to be practically used. Evidence supporting the validity and reliability were reported for n = 25 and n = 30 indicators respectively. The high number of indicators demonstrate the importance of measuring pressure ulcer prevention quality. This is not an indicator of our ability to accurately measure and evaluate this construct. There is an urgent need to develop evidence-based and internationally comparable indicators to help improve patient care and safety worldwide.

Clinical Evaluation of a Skin Protectant for the Management of Incontinence-Associated Dermatitis: An Open-Label, Nonrandomized, Prospective Study

PURPOSE:

The purpose of this study was to evaluate the efficacy of an investigational skin protectant product at managing severe skin breakdown associated with incontinence.

DESIGN:

Open-label, nonrandomized, prospective study.

SUBJECTS AND SETTING:

The sample comprised 16 patients; inclusion criteria were: patients older than 18 years, cared for in the intensive care unit of a level I trauma center hospital or in long-term care facilities in the northeast region of the United States, and had incontinence-associated dermatitis (IAD). Twelve of the patients had epidermal skin loss and 4 had severe redness.

METHODS:

The investigational product is a formulation based on acrylate chemistry. The skin protectant application schedule was twice weekly for up to 3 weeks for a maximum of 6 applications during the study period. The skin was evaluated via a skin assessment instrument specifically designed for use in this study; this instrument has not undergone validation studies. The main outcome measure was changes in the instrument score over time. In addition, complete reepithelialization was recorded when observed, and pain scores (associated with IAD) were noted in participants who were able to report pain.

RESULTS:

The IAD score improved in 13 of 16 patients, remained unchanged in 1 patient, and deteriorated in 2 patients. The median percent improvement in the skin assessment instrument was 96% (P = .013). Four of the patients with epidermal skin loss had complete reepithelialization of the skin surface with 4 to 6 applications of the skin protectant, and 5 had substantial improvement. The 4 patients with severe red skin returned to healthy normal skin with 2 to 4 skin protectant applications. Substantial pain reduction was reported by all 9 patients who reported pain at enrollment. No adverse events associated with the skin protectant application were reported during data collection.

CONCLUSION:

Results of this study suggest that an acrylate-based product, evaluated here for the first time in patients, may be effective as a protective barrier in the presence of continued incontinence. Additional research is needed to confirm these findings.

Incontinence Briefs Containing Spiral-Shaped Fiber Acidify Skin pH of Older Nursing Home Residents at Risk for Incontinence-Associated Dermatitis

PURPOSE

The study's purpose was to assess the pH of the skin of older (aged ≥75 years) incontinent nursing home residents after exposure to an incontinence brief containing spiral-shaped fiber wet with an alkaline solution mimicking urine or fecal pH and compared to skin pH after exposure to an industry standard brief wet with the same solution and various controls.

DESIGN

The design was experimental, as conditions were applied to skin and skin pH was measured in random order, and subjects served as their own controls.

SETTING AND SUBJECTS

The setting was a Midwestern nonprofit nursing home. The sample was 26 nursing home residents; their mean age was 87 years (SD = 6 years); 77% were female. Most (69%) had urinary incontinence alone, and 31% had dual urinary and fecal incontinence.

METHODS

Skin pH was measured in duplicate on 6 areas of the inner thighs and 6 areas of the volar surface of the forearms. Each area was exposed to 1 of 6 conditions applied in random order: an incontinence brief containing spiral-shaped fiber wet with an alkaline solution and one that was dry; a standard incontinence brief (without spiral-shaped fiber) wet with the same alkaline solution and one that was dry; the alkaline solution alone; and normal skin.

RESULTS

On both the thighs and the forearms, skin pH was significantly lower (more acidic) after exposure to the incontinence brief containing spiral-shaped fiber wet with an alkaline solution compared to the wet standard brief and all other control conditions (P < .001). On thighs, the mean skin pH was 5.7 (SD = 0.5) after exposure to the wet brief with spiral-shaped fiber versus 6.4 (SD = 0.5) after exposure to the wet standard brief. On forearms, the mean skin pH was 5.3 (SD = 0.4) after exposure to the wet brief with spiral-shaped fiber versus 6.0 (SD = 0.4) after exposure to the wet standard brief.

CONCLUSIONS

Incontinence briefs containing a spiral-shaped fiber significantly acidify the pH of the skin exposed to an alkaline solution, while industry standard briefs do not. Since alkaline skin pH is a risk factor for incontinence-associated dermatitis (IAD), results suggest that briefs with spiral-shaped fiber may help prevent IAD. Findings encourage further research.

cEEG electrode-related pressure ulcers in acutely hospitalized patients

BACKGROUND

Pressure ulcers resulting from continuous EEG (cEEG) monitoring in hospitalized patients have gained attention as a preventable medical complication. We measured their incidence and risk factors.

METHODS

We performed an observational investigation of cEEG-electrode-related pressure ulcers (EERPU) among acutely ill patients over a 22-month period. Variables analyzed included age, sex, monitoring duration, hospital location, application methods, vasopressor usage, nutritional status, skin allergies, fever, and presence/severity of EERPU. We examined risk for pressure ulcers vs monitoring duration using Kaplan-Meyer survival analysis, and performed multivariate risk assessment using Cox proportional hazard model.

RESULTS

Among 1,519 patients, EERPU occurred in 118 (7.8%). Most (n = 109, 92.3%) consisted of hyperemia only without skin breakdown. A major predictor was monitoring duration, with 3-, 5-, and 10-day risks of 16%, 32%, and 60%, respectively. Risk factors included older age (mean age 60.65 vs 50.3, p < 0.01), care in an intensive care unit (9.37% vs 5.32%, p < 0.01), lack of a head wrap (8.31% vs 27.3%, p = 0.02), use of vasopressors (16.7% vs 9.64%, p < 0.01), enteral feeding (11.7% vs 5.45%, p = 0.04), and fever (18.4% vs 9.3%, p < 0.01). Elderly patients (71-80 years) were at higher risk (hazard ratio 6.84 [1.95-24], p < 0.01), even after accounting for monitoring time and other pertinent variables in multivariate analysis.

CONCLUSIONS

EERPU are uncommon and generally mild. Elderly patients and those with more severe illness have higher risk of developing EERPU, and the risk increases as a function of monitoring duration.
