Pressure injury risk assessment and prescription of preventative interventions using a structured tool versus clinical judgement: An interrater agreement study. J Adv Nurs 2024. [PMID: 38450740 DOI: 10.1111/jan.16142] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 02/12/2024] [Accepted: 02/22/2024] [Indexed: 03/08/2024]
Abstract
AIM To assess agreement of pressure injury risk level and differences in preventative intervention prescription between nurses using a structured risk assessment tool compared with clinical judgement. DESIGN Interrater agreement study. METHODS Data were collected from November 2019 to December 2022. Paired nurse-assessors were allocated randomly to independently assess pressure injury risk using a structured tool (incorporating the Waterlow Score), or clinical judgement; then prescribe preventative interventions. Assessments were conducted on 150 acute patient participants in a general tertiary hospital. Agreement of risk level was analysed using absolute agreement proportions, weighted kappa and prevalence-adjusted and bias-adjusted kappa. RESULTS Ninety-four nurse assessors participated. Absolute agreement of not-at-risk versus at-risk-any-level was substantial, but absolute agreement of risk-level was only fair. Clinical judgement assessors tended to underestimate risk. Where risk level was agreed, prescribed intervention frequencies were similar, although structured tool assessors prescribed more interventions mandated by standard care, while clinical judgement assessors prescribed more additional/optional interventions. Structured tool assessors prescribed more interventions targeted at lower-risk patients, whereas assessors using clinical judgement prescribed more interventions targeted at higher-risk patients. CONCLUSION There were clear differences in pressure injury risk-level assessment between nurses using the two methods, with important differences in intervention prescription frequencies found. Further research is required into the use of both structured tools and clinical judgement to assess pressure injury risk, with emphasis on the impact of risk assessments on subsequent preventative intervention implementation. IMPACT The results of this study are important for clinical practice as they demonstrate the influence of using a structured pressure injury risk assessment tool compared to clinical judgement. Whilst further research is required into the use of both structured tools and clinical judgement to assess pressure injury risk and prescribe interventions, our findings do not support a change in practice that would exclude the use of a structured pressure injury risk assessment tool. REPORTING METHOD This study adhered to the GRRAS reporting guideline. PATIENT/PUBLIC CONTRIBUTION No patient or public involvement in this study. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE Educators and researchers can use the findings to guide teaching about pressure injury risk assessment and preventative intervention and to direct future studies. For clinical nurses and patients, a change in clinical practice that would exclude the use of a structured risk assessment tool is not recommended and further work is needed to validate the role of clinical judgement to assess risk and its impact on preventative intervention.

Abstract
BACKGROUND Medical tapes can lead to skin damage upon removal in susceptible patients with fragile skin and at higher risk of developing tissue injury. PURPOSE We compared the effect of medical tapes with silicone-based versus acrylate-based adhesives on the back or volar forearm stratum corneum using analytical techniques to assess skin condition and potential damage post product removal on 88 healthy volunteers. METHODS Two studies were conducted in separate facilities (Study 1: 3M In-house Clinical Facility, St. Paul, Minnesota; Study 2: DermiCo, LLC, Broomall, Pennsylvania). Four commercially available tapes were the same in both studies, two for each type of adhesive. We evaluated adhesion to the skin, total proteins and corneocytes removed by the tapes, changes in transepidermal water loss (TEWL), and induction of the inflammatory cytokine interleukin-1 alpha (IL-1a). RESULTS One of the silicone tapes displayed the strongest adhesion at 24 hours, and one of the acrylate tapes had the lowest adhesion, showing differences in performance within adhesive categories. The adhesion forces did not correlate with the amount of total protein or corneocytes removed. Silicone adhesives removed less total protein and corneocytes than acrylate adhesives. Silicone adhesives did not alter TEWL, whereas acrylate adhesives significantly raised TEWL. There were no differences in interleukin-1alpha induction. CONCLUSION The silicone adhesive tapes were less disruptive to the skin barrier than the acrylate adhesive tapes, even in healthy volunteers whose skin is not as fragile as what is observed in typical patients. This type of data could guide clinical product usage decisions.

Abstract
Skin tears, defined as traumatic wounds caused by mechanical forces, can be debilitating for individuals, causing pain and reduced mobility. Although skin tears can develop throughout the lifespan, older age can make the skin increasingly susceptible to this type of injury. Studies have found wide variation in the incidence and prevalence of skin tears, in part because of suboptimal recognition and reporting practices among healthcare professionals. Effective prevention of skin tears requires a standardised approach to risk assessment, prevention, recognition and classification, such as that offered by the International Skin Tear Advisory Panel (ISTAP) best practice recommendations. This article examines the literature on the incidence, prevalence, prevention and recognition of skin tears, and outlines some of the ISTAP best practice recommendations on risk assessment, prevention and recognition. The authors also consider the need for patient and healthcare professional education to optimise the prevention of skin tears.

Nutrition association with skin integrity and pressure injury in critically ill pediatric patients. Nutr Clin Pract 2023; 38 Suppl 2:S125-S138. [PMID: 37721464 DOI: 10.1002/ncp.11063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 07/23/2023] [Accepted: 07/24/2023] [Indexed: 09/19/2023] Open
Abstract
BACKGROUND Current research highlights the positive impact of nutrition therapy, particularly enteral nutrition, in critical illness. However, little attention is given to the impact of nutrition on skin integrity during critical illness. Skin integrity is at risk in critically ill children owing to necessary clinical therapies and challenges of providing nutrition therapy. METHODS We conducted a narrative literature review with three main thematic concepts to drive our literature search: the association of nutrition therapy with (1) skin integrity; (2) injury, wounds, and wound healing; and (3) differences of skin color. Using pertinent search and subject terms, PubMed, CINAHL, EMBASE, and SCOPUS databases were searched, yielding 316 articles. After removal of duplicates, articles were reviewed based on inclusion and exclusion criteria defined by the authors; only eight articles met the defined criteria to inform this review. RESULTS Large and important gaps exist in the current literature regarding an association between nutrition therapy, skin injury, and wound healing. Little to no attention was found for associations with skin color. The resulting narrative review addresses these topics and subtopics with additional references included that are independent of the original search strategy. CONCLUSIONS A dearth of evidence exists describing associations between nutrition and disruption of skin integrity in pediatric critical illness. Children with dark skin are at increased risk, as manifestation and identification of disruption to skin integrity may not be recognized. Research is needed to describe these associations and the impact of nutrition on skin integrity, including differences of skin color.

Abstract
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.

A Novel Perilla frutescens (L.) Britton Cell-Derived Phytocomplex Regulates Keratinocytes Inflammatory Cascade and Barrier Function and Preserves Vaginal Mucosal Integrity In Vivo. Pharmaceutics 2023; 15:pharmaceutics15010240. [PMID: 36678869 PMCID: PMC9861994 DOI: 10.3390/pharmaceutics15010240] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 12/31/2022] [Accepted: 01/04/2023] [Indexed: 01/13/2023] Open
Abstract
In the last years, the medicinal plant Perilla frutescens (L.) Britton has gained scientific interest because leaf extracts, due to the presence of rosmarinic acid and other polyphenols, have shown anti-allergic and skin protective potential in pre-clinical studies. Nevertheless, the lack of standardized extracts has limited clinical applications to date. In this work, for the first time, a standardized phytocomplex of P. frutescens, enriched in rosmarinic acid and total polyphenols, was produced through innovative in vitro cell culture biotechnology and tested. The activity of perilla was evaluated in an in vitro inflammatory model of human keratinocytes (HaCaT) by monitoring tight junctions, filaggrin, and loricrin protein levels, the release of pro-inflammatory cytokines and JNK MAPK signaling. In a practical health care application, the perilla biotechnological phytocomplex was tested in a multilayer model of vaginal mucosa, and then, in a preliminary clinical observation to explore its capacity to preserve vaginal mucosal integrity in women in peri-menopause. In keratinocytes cells, perilla phytocomplex demonstrated to exert a marked activity in epidermis barrier maintenance and anti-inflammatory effects, preserving tight junction expression and downregulating cytokines release through targeting JNK activation. Furthermore, perilla showed positive effects in retaining vaginal mucosal integrity in the reconstructed vaginal mucosa model and in vivo tests. Overall, our data suggest that the biotechnological P. frutescens phytocomplex could represent an innovative ingredient for dermatological applications.

Application of quantitative proteomics to discover biomarkers for tick resistance in cattle. Front Immunol 2023; 14:1091066.

Abstract
Introduction Breeding for tick resistance is a sustainable alternative to control cattle ticks due to widespread resistance to acaricidal drugs and the lack of a protective vaccine. The most accurate method used to characterise the phenotype for tick resistance in field studies is the standard tick count, but this is labour-intensive and can be hazardous to the operator. Efficient genetic selection requires reliable phenotyping or biomarker(s) for accurately identifying tick-resistant cattle. Although breed-specific genes associated with tick resistance have been identified, the mechanisms behind tick resistance have not yet been fully characterised. Methods This study applied quantitative proteomics to examine the differential abundance of serum and skin proteins using samples from naïve tick-resistant and -susceptible Brangus cattle at two-time points following tick exposure. The proteins were digested into peptides, followed by identification and quantification using sequential window acquisition of all theoretical fragment ion mass spectrometry. Results Resistant naïve cattle had a suite of proteins associated with immune response, blood coagulation and wound healing that were significantly (adjusted P < 10- 5) more abundant compared with susceptible naïve cattle. These proteins included complement factors (C3, C4, C4a), alpha-1-acid glycoprotein (AGP), beta-2-glycoprotein-1, keratins (KRT1 & KRT3) and fibrinogens (alpha & beta). The mass spectrometry findings were validated by identifying differences in the relative abundance of selected serum proteins with ELISA. The proteins showing a significantly different abundance in resistant cattle following early and prolonged tick exposures (compared to resistant naïve) were associated with immune response, blood coagulation, homeostasis, and wound healing. In contrast, susceptible cattle developed some of these responses only after prolonged tick exposure. Discussion Resistant cattle were able to transmigrate immune-response related proteins towards the tick bite sites, which may prevent tick feeding. Significantly differentially abundant proteins identified in this research in resistant naïve cattle may provide a rapid and efficient protective response to tick infestation. Physical barrier (skin integrity and wound healing) mechanisms and systemic immune responses were key contributors to resistance. Immune response-related proteins such as C4, C4a, AGP and CGN1 (naïve samples), CD14, GC and AGP (post-infestation) should be further investigated as potential biomarkers for tick resistance.

Systematic Review of the Effects of Positioning on Nonautonomic Outcomes in Preterm Infants. J Obstet Gynecol Neonatal Nurs 2023; 52:9-20. [PMID: 36309067 DOI: 10.1016/j.jogn.2022.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 09/10/2022] [Accepted: 09/26/2022] [Indexed: 11/05/2022] Open
Abstract
OBJECTIVE To identify and synthesize the available evidence on the effect of different positions (prone, supine, and right and left lateral) on nonautonomic outcomes for preterm infants admitted to the NICU. DATA SOURCES We searched the CINAHL, MEDLINE, Scopus, and Cochrane databases for reports of primary research studies using a three-step strategy. We also searched for gray literature and reviewed the reference lists of retrieved articles. STUDY SELECTION We included reports of quantitative studies published in English from database inception through February 2022 that focused on positioning and nonautonomic outcomes (pain, comfort, skin integrity, behavioral state, and sleep quality and duration) for preterm infants in the NICU. Two authors independently screened titles and abstracts and assessed articles in full text against the inclusion criteria. DATA EXTRACTION Two authors independently extracted the data from the full-text articles using a standardized data extraction tool. We synthesized the data narratively because of the different designs and outcome measures among the included studies. DATA SYNTHESIS From a total of 550 records initially screened, we included 17 articles in our review. In the included articles, prone positioning improved sleep quality and duration, whereas supine positioning was associated with increased awakenings and activity. Infants demonstrated fewer self-regulatory behaviors in the prone position compared to supine or side-lying and were less stressed in the prone position. We found minimal evidence on the effect of positioning on skin integrity or pain. CONCLUSION There is limited good-quality evidence on the effect of positioning on nonautonomic outcomes in preterm infants. To inform clinical practice, high-quality randomized controlled trials focused on the positioning of premature infants are warranted.

Abstract
INTRODUCTION Granzyme B is a serine protease extensively studied for its implication in cytotoxic lymphocyte-mediated apoptosis. In recent years, the paradigm that the role of granzyme B is restricted to immune cell-mediated killing has been challenged as extracellular roles for the protease have emerged. While mostly absent from healthy tissues, granzyme B levels are elevated in several autoimmune and/or chronic inflammatory conditions. In the skin, its accumulation significantly impairs proper wound healing. AREAS COVERED After an overview of the current knowledge on granzyme B, a description of newly identified functions will be presented, focussing on granzyme B ability to promote cell-cell and dermal-epidermal junction disruption, extracellular matrix degradation, vascular permeabilization, and epithelial barrier dysfunction. Progress in granzyme B inhibition, as well as the use of granzyme B inhibitors for the treatment of tissue damage, will be discussed. EXPERT OPINION The absence of endogenous extracellular inhibitors renders extracellular granzyme B accumulation deleterious for the proper healing of chronic wounds due to sustained proteolytic activity. Consequently, specific granzyme B inhibitors have been developed as new therapeutic approaches. Beyond applications in wound healing, other autoimmune and/or chronic inflammatory conditions related to exacerbated granzyme B activity may also benefit from the development of these inhibitors.

Abstract
The incidence of pressure ulcers is highest among older people with frailty. The development of pressure ulcers is a common and challenging issue in this population, which can reduce people's quality of life and increase mortality risk. Multifactorial processes contribute to the development of pressure ulcers in older people with frailty, including age-related skin changes, comorbidities, polypharmacy, reduced mobility, inadequate nutrition and hydration, and continence issues. This article discusses the development and management of pressure ulcers in older people with frailty. It also outlines some of the measures that can be taken by nurses and other healthcare professionals to reduce the risk of pressure ulcers developing in this population.

"Normal" TEWL-How Can it be Defined?: A Systematic Review. Exp Dermatol 2022; 31:1618-1631.

Abstract
BACKGROUND Transepidermal water loss (TEWL), the total non-eccrine sweat water evaporating from a given area of epidermis over time, is a measurement of skin barrier integrity. Skin diseases (e.g. psoriasis and atopic dermatitis) often result in transient increases in TEWL, so knowledge of "normal" TEWL values may be used to predict disease progression in dermatological settings. Variables such as age, race, and anatomic location have been suggested to affect TEWL, but current regulatory agencies have failed to control for additional variables of interest. Thus, this review summarizes variables that may cause TEWL variation. METHODS A comprehensive literature search was performed using Embase, PubMed, and Web of Science to find human studies that provided data on variables affecting TEWL. RESULTS 31 studies, analyzing 22 affecting TEWL, were identified. Variables causing increased TEWL were mask-use (n=1), Dry Eye Disease (n=1), Chronic Venous Disease (n=1), Coronary Artery Disease (n=1), age (infants vs. adults) (n=4), nourishment in infants (n=1), stress within individuals (n=2), Body Mass Index (n=2), bathing versus showering (n=2), and scratching/friction (n=1). Variables with decreases in TEWL were genetic variability with SNPs on chromosome 9q34.3 (n=1) and cancer-cachexia (n=1). CONCLUSION We summarized 12 variables that impact TEWL and are not typically controlled for in experimental settings. Therefore, defining normal TEWL may currently be problematic. Thus, regulatory agencies should provide stricter guidelines on proper measurement of TEWL to minimize human introduced TEWL variation, and we should continue to examine factors impacting individual skin integrity.

Newborn and elderly skin: two fragile skins at higher risk of pressure injury. Biol Rev Camb Philos Soc 2022; 97:874-895.

Abstract
Skin is a key organ maintaining internal homeostasis by performing many functions such as water loss prevention, body temperature regulation and protection from noxious substance absorption, microorganism intrusion and physical trauma. Skin ageing has been well studied and it is well known that physiological changes in the elderly result in higher skin fragility favouring the onset of skin diseases. For example, prolonged and/or high-intensity pressure may suppress local blood flow more easily, disturbing cell metabolism and inducing pressure injury (PI) formation. Pressure injuries (PIs) represent a significant problem worldwide and their prevalence remains too high. A higher PI prevalence is correlated with an elderly population. Newborn skin evolution has been less studied, but some data also report a higher PI prevalence in this population compared to older children, and several authors also consider this skin as physiologically fragile. In this review, we compare the characteristics of newborn and elderly skin in order to determine common features that may explain their fragility, especially regarding PI risk. We show that, despite differences in appearance, they share many common features leading to higher fragility to shear and pressure forces, not only at the structural level but also at the cellular and molecular level and in terms of physiology. Both newborn and elderly skin have: (i) a thinner epidermis; (ii) a thinner dermis containing a less-resistant collagen network, a higher collagen III:collagen I ratio and less elastin; (iii) a flatter dermal-epidermal junction (DEJ) with lower anchoring systems; and (iv) a thinner hypodermis, resulting in lower mechanical resistance to skin damage when pressure or shear forces are applied. At the molecular level, reduced expression of transforming growth factor β (TGFβ) and its receptor TGFβ receptor II (TβRII) is involved in the decreased production and/or increased degradation of various dermal extracellular matrix (ECM) components. Epidermal fragility also involves a higher skin pH which decreases the activity of key enzymes inducing ceramide deficiency and reduced barrier protection. This seems to be correlated with higher PI prevalence in some situations. Some data also suggest that stratum corneum (SC) dryness, which may disturb cell metabolism, also increases the risk of PI formation. Besides this structural fragility, several skin functions are also less efficient. Low applied pressures induce skin vessel vasodilation via a mechanism called pressure-induced vasodilation (PIV). Individuals lacking a normal PIV response show an early decrease in cutaneous blood flow in response to the application of very low pressures, reflecting vascular fragility of the skin that increases the risk of ulceration. Due to changes in endothelial function, skin PIV ability decreases during skin ageing, putting it at higher risk of PI formation. In newborns, some data lead us to hypothesize that the nitric oxide (NO) pathway is not fully functional at birth, which may partly explain the higher risk of PI formation in newborns. In the elderly, a lower PIV ability results from impaired functionality of skin innervation, in particular that of C-fibres which are involved in both touch and pain sensation and the PIV mechanism. In newborns, skin sensitivity differs from adults due to nerve system immaturity, but the role of this in PIV remains to be determined.

Abstract
OBJECTIVE Intensive care unit (ICU) patients possess multiple risk factors for developing loss of skin integrity, particularly incontinence-associated dermatitis (IAD). IAD is an inflammatory skin condition resulting from repeated and prolonged contact with urine, faeces or both. This study aimed to measure the incidence and clinical characteristics of adult ICU patients with IAD. METHOD This was a prospective observational study conducted over three months in an adult ICU. Included patients were ≥18 years who experienced faecal incontinence during their intensive care admission. Patients were excluded if they had an ileostomy or colostomy, had IAD on admission, or were continent of urine and faeces. Skin inspections were performed every second day on all recruited patients by trained research nurses. Other data were collected from patient medical records. RESULTS A total of 37 patients took part in the study. Incidence of IAD was 35.1%; 13 patients who had incontinence developed IAD. The mean time to onset of IAD was 3.69 days, median 3 days (SD: 1.8, range: 2-8 days). Of the 13 patients who developed IAD, 12 (92.3%) patients were initially assessed as having category 1 IAD and one (7.7%) patient was initially assessed with category 2 IAD. Of the patients with category 1 IAD, one patient (7.7%) progressed to category 2 IAD severity. CONCLUSION A larger sample is recommended to fully explore ICU patient characteristics and IAD development. The incidence of IAD in ICU patients was high at 35%, indicating this condition requires due consideration in ICU patients.

The effect of a basic skin care product on the structural strength of the dermo-epidermal junction: An exploratory, randomised, controlled split-body trial. Int Wound J 2021; 19:426-435.

Abstract
Skin ageing is associated with various structural alterations including a decreased strength of the dermo‐epidermal adhesion increasing the risk for shear type injuries (skin tears). Topical applications of basic skin care products seem to reduce skin tear incidence. The suction blister method leads to the artificial and controlled separation of dermis and epidermis. Therefore, time to blister formation may be used as outcome measuring the strength of dermo‐epidermal adhesion. We conducted an exploratory, randomised, controlled trial with a split‐body design on forearms in healthy female subjects (n = 12; mean age 70.3 [SD 2.1] years). Forearms assigned to the intervention were treated twice daily with petrolatum for 8 weeks. Suction blisters were induced on forearms after 4 and 8 weeks and time to blister formation was measured. Stratum corneum and epidermal hydration were measured and epidermal thickness was assessed via optical coherence tomography. Time to blistering was longer and stratum corneum as well as epidermal hydration was consistently higher in intervention skin areas. We conclude that topical application of basic skin care products may improve mechanical adhesion of the dermo‐epidermal junction and that the parameter “time to blistering” is a suitable outcome to measure dermo‐epidermal adhesion strength in clinical research.

Abstract
Squamous cell carcinoma (SCC) is a global public health burden originating in epidermal stem and progenitor cells (ESPCs) of the skin and mucosa. To understand how genetic risk factors contribute to SCC, studies of ESPC biology are imperative. Children with Fanconi anemia (FA) are a paradigm for extreme SCC susceptibility caused by germline loss-of-function mutations in FA DNA repair pathway genes. To discover epidermal vulnerabilities, patient-derived pluripotent stem cells (PSCs) conditional for the FA pathway were differentiated into ESPCs and PSC-derived epidermal organotypic rafts (PSC-EORs). FA PSC-EORs harbored diminished cell-cell junctions and increased proliferation in the basal cell compartment. Furthermore, desmosome and hemidesmosome defects were identified in the skin of FA patients, and these translated into accelerated blistering following mechanically induced stress. Together, we demonstrate that a critical DNA repair pathway maintains the structure and function of human skin and provide 3D epidermal models wherein SCC prevention can now be explored.

Abstract
Pressure ulcers are painful, costly and can negatively affect a patient's quality of life. It has long been recognised that they increase the risk of infection, prolong hospital stays and can result in death. To prevent the occurrence of pressure ulcers, nurses need to understand what a pressure ulcer is and the underlying factors that cause them. Furthermore, it is essential that they recognise why some people are more susceptible to pressure and shear forces than others, so that preventable factors can be addressed. Nursing care to prevent pressure ulcers needs to be planned, implemented and evaluated in a systematic manner following an assessment of the patient and their circumstances. The 'aSSKINg' (assess risk; skin assessment and skin care; surface; keep moving; incontinence and moisture; nutrition and hydration; and giving information or getting help) model ensures all fundamental aspects of pressure ulcer prevention are included in patient care. This article outlines the definitions and causes of pressure ulcers, and explains how nurses can assess, plan, implement and evaluate pressure ulcer preventative care using the aSSKINg model as a guide.

Abstract
The harmful effects of excessive moisture on a patient's skin are well known. While traditionally considered an issue only encountered in continence care and older people, it is now recognised that the harmful effects of excessive moisture can occur across the lifespan and in various patient groups. The term 'moisture-associated skin damage' describes the spectrum of inflammatory damage that occurs in response to the prolonged exposure of a patient's skin to perspiration, urine, faeces or wound exudate. It is generally accepted that moisture-associated skin damage consists of four conditions: incontinence-associated dermatitis, intertrigo, peristomal moisture-associated dermatitis, and periwound moisture-associated dermatitis. This article describes the aetiologies of each of the different types of moisture-associated skin damage, and outlines the nursing interventions required for their prevention and management.

Abstract
Low frequency ultrasound-assisted drug delivery has been widely investigated as a non-invasive method to enhance the transdermal penetration of drugs. Using this technique, a brief application of ultrasound is used to permeabilize skin for a prolonged time. In this review, an overview on ultrasound is detailed to help explain the parameters that could be modulated to obtain the desired ultrasound parameters for enhanced transdermal drug delivery. The mechanisms of enhancement and the latest developments in the area of ultrasound-assisted transdermal drug delivery are discussed. Special emphasis is placed on the effects of ultrasound when used in combination with microneedles, electroporation and iontophoresis, and penetration enhancers. Further, this review summarizes the effect of ultrasound on skin integrity and the regulatory requirements for commercialization of the ultrasound based transdermal delivery instruments.

Abstract
PURPOSE Skin-related issues have a significant impact on health, activities of daily living, and quality of life among people with spina bifida. Data presented by select clinics that participate in the National Spina Bifida Patient Registry reported that 26% of individuals had a history of pressure injuries with 19% having had one in the past year. The spina bifida community lack direct guidelines on prevention of these and other skin related issues. The Integument (skin) Guidelines focus on prevention, not treatment, of existing problems. METHODS Using a consensus building methodology, the guidelines were written by experts in spina bifida and wound care. RESULTS The guidelines include age-grouped, evidence-based guidelines written in the context of an understanding of the whole person. They are presented in table format according to the age of the person with spina bifida. CONCLUSION These guidelines present a standardized approach to prevention of skin-related issues in spina bifida. Discovering what results in successful minimization of skin-related issues with testing of technology or prevention strategies is the next step in protecting this vulnerable population.

Pressure ulcer Cat. II-IV incidence on the CuroCell S.A.M. PRO powered reactive air support surface in a high-risk population: A multicentre cohort study in 12 Belgian nursing homes. Int Wound J 2019; 17:124-131. [PMID: 31713351 DOI: 10.1111/iwj.13242] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 09/16/2019] [Accepted: 09/18/2019] [Indexed: 12/14/2022] Open
Abstract
The primary objective was to study pressure ulcer (PU) category II-IV (including suspected deep tissue injury and unstageable PUs) cumulative incidence and PU incidence density, in a 30day observation period, associated with the use of the CuroCell S.A.M. PRO powered reactive air support surface in nursing home residents at risk for PU development. Secondary objectives were to study (a) PU category I cumulative incidence and PU incidence density and (b) user (caregivers and residents) experiences and perceptions of comfort associated with the use of the support surface under study. A multicentre cohort study was set up in 37 care units of 12 Belgian nursing homes. The sample consisted of 191 residents at risk of PU development (Braden score ≤ 17). The cumulative PU incidence was 4.7% (n = 9). The PU incidence density was 1.7/1000 observation days (9 PU/5370 days). The experience and perceptions of comfort analysis revealed that the CuroCell S.A.M. PRO powered reactive air support surface was comfortable for daily use. The mode of action and the quietness of the pump function had a positive impact on sleep quality. Patient comfort and sleep quality are essential criteria in the selection of a support surface.

Abstract
While medical technology is continuing to improve healthcare outcomes and quality of life for patients, the number of people affected by medical device-related skin damage is increasing. In many cases, life-preserving medical devices used in interventions such as nasal continuous positive airway pressure or oxygen therapy can cause significant skin damage, with negative consequences including pain, infection and delayed hospital discharge. This article outlines methods that nurses can use to minimise the risk of skin damage, focusing primarily on the prevention of pressure ulcers. It also examines how nurses can work collaboratively with patients, manufacturers and regulatory bodies to reduce the risk of medical device-related skin damage in the future.

Abstract
Why you should read this article: The skin is the largest organ of the body and provides protection for the vital organs, as well as having a significant role in processes such as temperature regulation. However, the ageing process involves degenerative changes such as reduced cell replacement and less efficient barrier function. These changes have physical and psychosocial consequences for older people such as increased susceptibility to skin damage and lowered self-esteem. This article details the age-associated changes that affect the skin, explores the self-reported skin concerns of older people living in the community, and examines the role of primary care nurses in promoting older people's skin health.

Abstract
Efficient topical delivery of imidazolic antifungals faces the challenge of overcoming its limited water solubility and its required long-lasting duration of treatments. In this paper, a hydrophilic multiple emulsion (ME) of Bifonazole (BFZ) is shown to maximize its skin retention, minimize its skin permeation, and maintain an acceptable level of being harmless in vivo. The formulations were pharmaceutically characterized and application properties were assessed based on viscosity measurements. Non-Newtonian pseudoplastic shear thinning with apparent thixotropy was observed, facilitating the formulation retention over the skin. The in vitro release profile with vertical diffusion cells showed a predominant square-root release kinetic suggesting an infinite dose depletion from the formulation. Ex vivo human skin permeation and penetration was additionally evaluated. Respective skin permeation was lower than values obtained with a commercial O/W formulation. The combination of amphoteric and non-ionic surfactants increased the bifonazole epidermal accumulation by a factor of twenty. This fact makes the possibility of increasing its current 24 h administration frequency more likely. Eventual alterations of skin integrity caused by the formulations were examined with epidermal histological analysis and in vivo preclinical measurements of skin elasticity and water retrograde permeation. Histological analysis demonstrated that the multiple emulsions were harmless. Additionally, modifications of in vivo skin integrity descriptors were considered as negligible.

Abstract
OBJECTIVE To identify variables during surgery that may contribute to the development of pressure ulcers (PUs) in postoperative, intensive care unit (ICU) patients within 72 hours of admission, as well as over their entire ICU admission. Furthermore, to investigate how these variables may impact on the number of PUs acquired. METHOD In a three-year retrospective audit, from 1 January 2014 to 31 December 2016, data from the electronic medical records of 3484 postoperative ICU patients in a major Australian metropolitan public hospital were retrieved and analysed to investigate associations between perioperative variables and PU occurrence. RESULTS A total of 69 ICU admissions (1.98%) out of 3484 resulted in at least one PU developing within the ICU. No specific variables were associated with the development of a PU within 72 hours of the patient's ICU admission. Multiple regression Cox analysis showed that length of time in the operating theatre (OT) (p=0.045), surgical specialty (p<0.001), 1-4 hypotensive episodes (p=0.017) and >5 hypotensive episodes (p<0.0005) were significantly associated with PU risk. Multivariable negative binomial regression demonstrated APACHE II score (p<0.01), OT time (p<0.01) and surgical specialty (p<0.01) were associated with PU number. CONCLUSION There are many risks to skin integrity at the perioperative period, and these risks may exert their effect well into the ICU admission period. It is imperative to identify and mitigate these factors in order to reduce PU incidence, morbidity and mortality.

Abstract
AIMS AND OBJECTIVES To evaluate the implementation of the Champions for Skin Integrity model on facilitating uptake of evidence-based wound management and improving skin integrity in residents of aged care facilities. BACKGROUND The incidence of skin tears, pressure injuries and leg ulcers increases with age, and such wounds can be a serious issue in aged care facilities. Older adults are not only at higher risk for wounds related to chronic disease but also injuries related to falls and manual handling requirements. DESIGN A longitudinal, pre-post design. METHODS The Champions for Skin Integrity model was developed using evidence-based strategies for transfer of evidence into practice. Data were collected before and six months after implementation of the model. Data on wound management and skin integrity were obtained from two random samples of residents (n = 200 pre; n = 201 post) from seven aged care facilities. A staff survey was also undertaken (n = 126 pre; n = 143 post) of experience, knowledge and evidence-based wound management. Descriptive statistics were calculated for all variables. Where relevant, chi-square for independence or t-tests were used to identify differences between the pre-/postdata. RESULTS There was a significant decrease in the number of residents with a wound of any type (54% pre vs 43% post, χ2 4·2, p = 0·041), as well as a significant reduction in specific wound types, for example pressure injuries (24% pre vs 10% post, χ2 14·1, p < 0·001), following implementation of the model. An increase in implementation of evidence-based wound management and prevention strategies was observed in the postimplementation sample in comparison with the preimplementation sample. This included use of limb protectors and/or protective clothing 6% pre vs 20% post (χ2 17·0, p < 0·001) and use of an emollient or soap alternative for bathing residents (50% pre vs 74% post, χ2 13·9, p = 0·001). CONCLUSIONS Implementation of the model in this sample fostered an increase in implementation of evidence-based wound management and prevention strategies, which was associated with a decrease in the prevalence and severity of wounds. RELEVANCE TO CLINICAL PRACTICE This study suggests the Champions for Skin Integrity model has the potential to improve uptake of evidence-based wound management and improve skin integrity for older adults.

An evidence-based approach to the prevention and initial management of skin tears within the aged community setting: a best practice implementation project. ACTA ACUST UNITED AC 2015; 13:421-43. [PMID: 26455614 DOI: 10.11124/jbisrir-2015-2073] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2014] [Revised: 04/28/2015] [Accepted: 04/30/2015] [Indexed: 10/31/2022]
Abstract
BACKGROUND Maintaining skin integrity in a community setting is an ongoing issue, as research suggests that the prevalence of skin tears within the community is greater than that in an institutional setting. While skin tear prevention and management principles in these settings are similar to those in an acute care setting, consideration of the environmental and psychological factors of the client is pivotal to prevention in a community setting. Evidence suggests that home environment assessment, education for clients and care givers, and being proactive in improving activities of daily living in a community setting can significantly reduce the risk of sustaining skin tears. OBJECTIVES The aim of this implementation project was to assess and review current skin tear prevention and management practices within the community setting, and from this, to implement an evidence-based approach in the education of clients and staff on the prevention of skin tears. As well. the project aims to implement evidence-based principles to guide clinical practice in relation to the initial management of skin tears, and to determine strategies to overcome barriers and non-compliance. METHODS The project utilized the Joanna Brigg's Institute Practical Application of Clinical Evidence System audit tool for promoting changes in the community health setting. The implementation of this particular project is based in a region within Anglicare Southern Queensland. A small team was established and a baseline audit carried out. From this, multiple strategies were implemented to address non-compliance which included education resources for clients and caregivers, staff education sessions, and creating skin integrity kits to enable staff members to tend to skin tears, and from this a follow-up audit undertaken. RESULTS Baseline audit results were slightly varied, from good to low compliance. From this, the need for staff and client education was highlighted. There were many improvements in the audit criteria following client and staff education sessions and staff self-directed learning packages. Future strategies required to sustain improvements in practice and make further progress are to introduce a readily available Anglicare Skin Integrity Assessment Tool to the nursing staff for undertaking new client admissions over 65 years, and to provide ongoing education to staff members, clients and care givers in order to reduce the prevalence of skin tears in the community setting. CONCLUSIONS This implementation project demonstrated the importance of education of personal care workers, clients and their caregivers for prevention of skin tears in the community setting. This in turn created autonomy and empowered clients to take control of their health.

Abstract
Maintaining skin integrity is an essential part of ensuring health and wellbeing in older people, and personal hygiene and emollient practices are central in achieving this aim. As nurses we are expected to deliver evidence-based care. However, there is a significant lack of evidence about how best we should provide day-to-day care that promotes skin health for older people. This article briefly examines the concept of evidence-based practice, reveals the gap in knowledge on skin hygiene and emollient practices for older people and justifies the need for a systematic review in this area. Finally it introduces a Cochrane protocol for a review that will collate and review existing knowledge and identify areas for future research. The application to practice of the new evidence generated either by the Cochrane review or by subsequent research is examined.

Abstract
The aim of this analysis was to identify the association between incontinence-associated dermatitis (IAD), its most important etiologic factors (incontinence and moisture), and pressure ulcers (PUs). A systematic review and meta-analysis were performed. We searched Medline, Embase, CINAHL, Web of Science, and the Cochrane Library for relevant papers dating through March 15, 2013. Fifty-eight studies were included. Measures of relative effect at the univariate level were meta-analyzed. In most studies (86%), a significant association between variables of interest was found, with pooled odds ratios of PUs in univariate models between 1.92 (95% CI 1.54-2.38) for urinary incontinence and 4.99 (95% CI 2.62-9.50) for double incontinence (p < .05). This evidence indicates an association between IAD, its most important etiological factors, and PUs. Methodological issues should be considered when interpreting the results of this review.

Abstract
AIM This article presents a discussion of the current state of knowledge about bariatric skin-hygiene care and whether this is sufficient to underpin evidence-based nursing practice. BACKGROUND The challenges of providing bariatric skin-hygiene care are highlighted and include managing specific skin changes with associated risk of skin breakdown and practical management needs. The risk of skin breakdown is high and can have a devastating impact on well-being and increased treatment costs. DATA SOURCES A four-stage search strategy included: (i) literature search using electronic databases from inception-May 2013; (ii) hand search of selected journals; (iii) review of internet-based guidelines, policies or protocols and (iv) contact with clinical experts. DISCUSSION There is a dearth of robust evidence on bariatric skin-hygiene care. Whilst a range of information and guidelines exist, these are generally based on expert opinion and often used only in a local context. IMPLICATIONS FOR NURSING Nurses are increasingly faced with the challenge of providing skin-hygiene care for patients with bariatric needs. At present, care is largely based on custom and practice or clinical opinion; this limits capacity to provide optimum evidence-based nursing care. CONCLUSION As the prevalence of people needing bariatric skin-hygiene care continues to increase, there is a lack of evidence to inform interventions and hence a growing need for further research in this challenging clinical area to help nurses and patients select the best possible interventions that will meet individual personal-hygiene needs and preserve skin integrity.
