Patients' experience of incontinence and incontinence-associated dermatitis in hospital settings: a qualitative study.

OBJECTIVE: To explore the experience of patients with incontinence and incontinence-associated dermatitis (IAD) in acute care hospitals and their family caregivers, including their perceptions and management, as well as the impact on their wellbeing. METHOD: A qualitative exploratory study design was employed in 18 wards across six acute/subacute hospitals in New South Wales, Australia. Patients with incontinence (with or without IAD) were invited to participate. Where interviews were not possible with the patient, their family caregiver was invited to participate. Semi-structured interviews were conducted. RESULTS: There were 45 interviewees in the study; 41 were patients with incontinence (11 of whom had IAD) and four were family caregivers. The experience of incontinence was captured by three themes: 'incontinence interrupts every aspect of my life'; 'actively concealing and cloaking'; and 'perceived as irreversible'. Incontinence was expected by the patients at their age and did not come as a surprise. It was normalised and approached with stoicism. As such, patients self-managed their incontinence by developing strategies to ensure they avoided episodes of incontinence during their stay. Incontinence left patients feeling anxious, embarrassed and with a sense of shame, and they did not communicate these feelings, or engage with health professionals about their incontinence, nor did health professionals discuss their incontinence with them. There was a strong sense of resignation that incontinence was irreversible and nothing could be done to improve it. All participants displayed little knowledge of IAD. The experience of having IAD was characterised by the theme 'debilitating and desperate for relief' and was experienced as a particularly painful, itching and burning condition that left patients distressed and irritable. CONCLUSION: Patients with incontinence in acute settings required further education from health professionals to reduce the stigma of incontinence, and provide further support to manage their incontinence. Health professionals can also play a key role in educating patients about the risks of developing IAD and how it can be prevented.

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

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

The Viability and Acceptability of a Virtual Wound Care Command Centre in Australia.

The objective of this study was to assess the viability and acceptability of an innovative Virtual Wound Care Command Centre where patients in the community, and their treating clinicians, have access to an expert wound specialist service that comprises a digital wound application (app) for wound analysis, decision-making, remote consultation, and monitoring. Fifty-one patients with chronic (42.6%) wounds were healed, with a median time to healing of 66 (95% CI: 56-88) days. All patients reported high satisfaction with their wound care, 86.4% of patients recommended the Virtual Wound Care Command Centre with 84.1% of patients reporting the app as easy to use. The data revealed that the Virtual Wound Care Command Centre was a viable and acceptable patient-centred expert wound consultation service for chronic wound patients in the community.

Reshaping Wound Care: Evaluation of an Artificial Intelligence App to Improve Wound Assessment and Management.

This study evaluated the usability and effectiveness of an artificial intelligence application for wound assessment and management from a clinician-and-patient perspective. A quasi-experimental design was conducted in four settings in an Australian health service. Data were collected from patients in the standard (n=166,243 wounds) and intervention (n=124,184 wounds) group, at baseline and post-intervention. Clinicians completed a survey (n=10) and focus group (n=13) and patients were interviewed (n=4). Wound documentation were analysed descriptively, bivariate statistics determined between-group differences, and interviews were thematically analysed. Compared with the standard group, wound documentation in the intervention group improved significantly (<2 items documented 24% vs 70%, P < .001). During the intervention, 101/132 wounds improved (mean wound size reduction=53.99%). Positive evaluations included instantaneous objective wound assessment, shared wound plans increased patient adherence and enhanced efficiency in providing virtual care. Application use facilitated remote patient monitoring and reduced patient travel time while maintaining optimal wound care.

Pressure injury prevention practice in Australian intensive care units: A national cross-sectional survey.

INTRODUCTION: Pressure injury (PI) is an ongoing problem for patients in intensive care units (ICUs). The aim of this study was to explore the nature and extent of PI prevention practices in Australian adult ICUs. MATERIALS AND METHODS: An Australian multicentre, cross-sectional study was conducted via telephone interview using a structured survey instrument comprising six categories: workplace demographics, patient assessment, PI prevention strategies, medical devices, skin hygiene, and other health service strategies. Publicly funded adult ICUs, accredited with the College of Intensive Care Medicine, were surveyed. Data were analysed using descriptive statistics and chi-square tests for independence to explore associations according to geographical location. RESULTS: Of the 75 eligible ICUs, 70 responded (93% response rate). PI was considered problematic in two-thirds (68%) of all ICUs. Common PI prevention strategies included risk assessment and visual skin assessment conducted within at least 6 h of admission (70% and 73%, respectively), a structured repositioning regimen (90%), use of barrier products to protect the skin (94%), sacrum or heel prophylactic multilayered silicone foam dressings (88%), regular PI chart audits (96%), and PI quality improvement projects (90%). PI prevention rounding and safety huddles were used in 37% of ICUs, and 31% undertook PI research. Although most ICUs were supported by a facility-wide skin integrity service, it was more common in metropolitan ICUs than in rural and regional ICUs (p < 0.001). Conversely, there was greater involvement of occupational therapists in PI prevention in rural or regional ICUs than in metropolitan ICUs (p = 0.026). DISCUSSION AND CONCLUSION: This is the first study to provide a comprehensive description of PI prevention practices in Australian ICUs. Findings demonstrate that PI prevention practices, although nuanced in some areas to geographical location, are used in multiple and varied ways across ICUs.

The viability and acceptability of a Virtual Wound Care Command Centre in Australia.

The objective of this study was to assess the viability and acceptability of an innovative Virtual Wound Care Command Centre where patients in the community, and their treating clinicians, have access to an expert wound specialist service that comprises a digitally enabled application for wound analysis, decision-making, remote consultation, and monitoring. Fifty-one patients with chronic wounds from 9 centres, encompassing hospital services, outpatient clinics, and community nurses in one metropolitan and rural state in Australia, were enrolled and a total of 61 wounds were analysed over 7 months. Patients received, on average, an occasion of service every 4.4 days, with direct queries responded to in a median time of 1.5 hours. During the study period, 26 (42.6%) wounds were healed, with a median time to healing of 66 (95% CI: 56-88) days. All patients reported high satisfaction with their wound care, 86.4% of patients recommended the Virtual Wound Care Command Centre with 84.1% of patients reporting the digital wound application as easy to use. Potential mean travel savings of $99.65 for rural patients per visit were recognised. The data revealed that the Virtual Wound Care Command Centre was a viable and acceptable patient-centred expert wound consultation service for chronic wound patients in the community.

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

BACKGROUND: Incontinence-associated dermatitis is a common, under-recognized painful skin condition associated with poorer quality of life, increased nurse workloads, and costs. OBJECTIVE: To systematically review economic evidence for the prevention and treatment of incontinence-associated dermatitis. DESIGN: Systematic review of quantitative research. DATA SOURCES: PubMed, MEDLINE, EMBASE, Cochrane Library, York Centre for Reviews and Dissemination database, Econlit, Tufts' Cost-Effectiveness Analysis Registry, and Web of Science. REVIEW METHODS: A comprehensive search for studies on resource use (costs), health outcomes, and cost-effectiveness of interventions for incontinence-associated dermatitis was conducted. Screening, data extraction, and initial quality assessment were conducted independently by two reviewers, with disagreements/queries regarding quality settled through consensus with the larger team. Quality evaluated using the Consolidated Health Economic Evaluation Reporting Standards checklist and results narratively arranged. FINDINGS: Seventeen studies (10 for prevention, one for treatment and six for both prevention and treatment) included. All studies measured resource use from a healthcare provider perspective; 14 quantified resources in monetary terms. Considerable variation existed in the resource use data primarily due to differences in the type of resources counted, selected time horizons, valuation methods, and reporting approaches. Ten studies provided evidence of their intervention to be cost saving (or at least cost avoiding). Five studies on barrier products provided evidence to be cost saving: three for prevention, one for treatment, and one for both prevention and treatment. Two studies of cleanser and barrier products provided evidence to be cost saving for the prevention and treatment of incontinence-associated dermatitis. One study found a cleanser to be a cost saving preventative intervention. One bowel management system was found to be cost saving over time only, and one nurse education intervention was found to be cost saving for preventing and treating incontinence-associated dermatitis. One barrier product was found to be cost-effective for preventing and treating the condition. Finally, one study found a cleanser and barrier product was time saving for prevention. None of the studies incorporated a multi-attribute quality of life measure; however, two studies included person-reported outcome measures for pain. A narrow range of resources (mainly products) were considered, and there was limited information on how they were counted and valued. Analyses relating to heterogeneity among patients/hospital wards or health facilities and uncertainty were lacking. CONCLUSIONS: Barrier products are possibly a more cost-effective treatment than others; however, this evidence lacks certainty. Structured health economic evaluations are required for a reliable evidence-base on the interventions for incontinence-associated dermatitis. TWEETABLE ABSTRACT: Most incontinence-associated dermatitis studies lack person-reported outcomes, costs beyond product/staff time, and economic evaluation.

Efficacy of a heel offloading boot in reducing heel pressure injuries in patients in Australian intensive care units: A single-blinded randomised controlled trial.

OBJECTIVES: To compare time to incidence, extent of incidence and severity of heel pressure injury with a heel off-loading boot (intervention) or pillows (control). RESEARCH METHODOLOGY/DESIGN: Multi-centre, single-blinded randomised controlled trial of 394 critically ill patients. Patients were randomised to the intervention or control for heel offloading. SETTING: Three hospital intensive care units; two in greater Sydney, Australia and one in regional New South Wales, Australia. MAIN OUTCOME MEASURES: Time to intensive care unit-acquired pressure injury in heels of patients without pre-existing heel pressure injury within 28 days from intensive care unit admission. SECONDARY OUTCOMES: incidence of heel pressure injury within 28 days of intensive care unit admission; severity of intensive care unit-acquired heel pressure injuries; occurrence of plantar contractures (a change in ankle dorsiflexion of 5° or greater) within 28 days of admission. RESULTS: Within 28 days of admission, one pressure injury was recorded in the intervention group and 11 in the control group. Hazard of pressure injury incidence within 28 days of admission was significantly lower (p = 0.0239) in heels assigned to the intervention (hazard ratio 0.0896 [95% CI 0.0110, 0.727]). Odds of pressure injury incidence within 28 days of admission were significantly lower (p = 0.0261) in the intervention group (odds ratio 0.0883 [95% CI 0.0104, 0.749]). The pressure injury recorded in the intervention group was superficial (stage 1) whereas those recorded in the control group were more severe (stage 2 to 4). CONCLUSION: The heel-offloading boot used in this study significantly reduced heel pressure injury occurrence compared with heel offloading using pillows.

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.

Reshaping wound care: Evaluation of an artificial intelligence app to improve wound assessment and management amid the COVID-19 pandemic.

Wound documentation is integral to effective wound care, health data coding and facilitating continuity of care. This study evaluated the usability and effectiveness of an artificial intelligence application for wound assessment and management from a clinician-and-patient user perspective. A quasi-experimental design was conducted in four settings in an Australian health service. Data were collected from patients in the standard group (n = 166, 243 wounds) and intervention group (n = 124, 184 wounds), at baseline and post-intervention. Clinicians participated in a survey (n = 10) and focus group interviews (n = 13) and patients were interviewed (n = 4). Wound documentation data were analysed descriptively, and bivariate statistics were used to determine between-group differences. Thematic analysis of interviews was conducted. Compared with the standard group, wound documentation in the intervention group improved significantly (more than two items documented 24% vs 70%, P < .001). During the intervention, 101 out of 132 wounds improved (mean wound size reduction = 53.99%). Positive evaluations identified improvements such as instantaneous objective wound assessment, shared wound plans, increased patient adherence and enhanced efficiency in providing virtual care. The use of the application facilitated remote patient monitoring and reduced patient travel time while maintaining optimal wound care.

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.

Pressure injury prevalence in Australian intensive care units: A secondary analysis.

BACKGROUND: Pressure injuries (PIs) are an enduring problem for patients in the intensive care unit (ICU) because of their vulnerability and numerous risk factors. METHOD: This study reports Australian data as a subset of data from an international 1-day point prevalence study of ICU-acquired PI in adult patients. Patients aged 18 years or older and admitted to the ICU on the study day were included. The outcome measure was the identification of a PI by direct visual skin assessment on the study day. Data collected included demographic data and clinical risk factors, PI location and stage, and PI prevention strategies used. Descriptive statistics were used to describe PI characteristics, and odds ratios (ORs) were used to identify factors associated with the development of a PI. RESULTS: Data were collected from 288 patients from 16 Australian ICUs. ICU-acquired PI prevalence was 9.7%, with 40 PIs identified on 28 patients. Most PIs were of stage 1 and stage 2 (26/40, 65.0%). Half of the ICU-acquired PIs were found on the head and face. The odds of developing an ICU-acquired PI increased significantly with renal replacement therapy (OR: 4.25, 95% confidence interval [CI]: 1.49-12.11), impaired mobility (OR: 3.13, 95% CI: 1.08-9.12), fastest respiratory rate (OR: 1.05 [per breath per minute], 95% CI: 1.00-1.10), longer stay in the ICU (OR: 1.04 [per day], 95% CI: 1.01-1.06), and mechanical ventilation on admission (OR: 0.36, CI: 0.14-0.91). CONCLUSION: This study found that Australian ICU-acquired PI prevalence was 9.7% and these PIs were associated with many risk factors. Targeted PI prevention strategies should be incorporated into routine prevention approaches to reduce the burden of PIs in the Australian adult ICU patient population.

Understanding Skin Failure: A Scoping Review.

OBJECTIVE: To map the use of the term "skin failure" in the literature over time and enhance understanding of this term as it is used in clinical practice. DATA SOURCES: The databases searched for published literature included PubMed, Embase, the Cumulative Index for Nursing and Allied Health Literature, and Google Scholar. The search for unpublished literature encompassed two databases, Open Gray and ProQuest Dissertation and Theses. STUDY SELECTION: Search terms included "skin failure," "acute skin failure," "chronic skin failure," and "end stage skin." All qualitative and quantitative research designs, editorial, opinion pieces, and case studies were included, as well as relevant gray literature. DATA EXTRACTION: Data collected included author, title, year of publication, journal name, whether the term "skin failure" was mentioned in the publication and/or in conjunction with other skin injury, study design, study setting, study population, sample size, main focus of the publication, what causes skin failure, skin failure definition, primary study aim, and primary outcome. DATA SYNTHESIS: Two main themes of skin failure were identified through this scoping review: the etiology of skin failure and the interchangeable use of definitions. CONCLUSIONS: Use of the term "skin failure" has increased significantly over the past 30 years. However, there remains a significant lack of empirical evidence related to skin failure across all healthcare settings. The lack of quality research has resulted in multiple lines of thinking on the cause of skin failure, as well as divergent definitions of the concept. These results illustrate substantial gaps in the current literature and an urgent need to develop a globally agreed-upon definition of skin failure, as well as a better understanding of skin failure etiology.

Device-related pressure injuries in adult intensive care unit patients: An Australian and New Zealand point prevalence study.

BACKGROUND: Device-related pressure injuries (DRPIs) are an ongoing iatrogenic problem evident in intensive care unit (ICU) settings. Critically ill patients are at high risk of developing pressure injuries caused by devices. OBJECTIVE: The aim of the study was to determine the prevalence of DRPI in critically ill patients in intensive care and the location, stage, and attributable device of DRPI and describe the products and processes of care used to prevent these injuries. METHODS: This was a prospective, multicentre, cross-sectional point prevalence study of patients aged more than 16 years in Australian and New Zealand ICUs. The study was part of the Australian and New Zealand Intensive Care Society Clinical Trials Group Point Prevalence Program coordinated by The George Institute for Global Health. MAIN OUTCOME MEASURE: Identification of DRPI on the study day was the main outcome measure. RESULTS: Of the 624 patients included from 44 participating ICUs, 27 were found to have 35 identified DRPIs, giving a point prevalence DRPI rate of 4.3% (27/624). Study patients had a mean age of 59 years, and 60.3% were men. Patients with DRPI compared with patients without DRPI were significantly heavier (median: 92 kg versus 80 kg, respectively, p = 0.027), were less likely to survive the ICU (63.0% versus 85.9%, respectively, p = 0.015), had higher Acute Physiology and Chronic Health Evaluation II scores at admission to the ICU (median: 20 versus 16, respectively, p = 0.001), received mechanical ventilation more often (88.9% versus 43.5%, respectively, p < 0.001), and were more frequently diagnosed with respiratory conditions (37.0% versus 18.6%, respectively, p = 0.022). Processes of care activities were surveyed in 42 ICUs. Most DRPIs were attributed to endotracheal tubes and other respiratory devices. Forty-two ICUs reported processes of care to prevent DRPI, and just more than half of the participating sites (54.8%, 23/44) reported a dedicated ICU-based protocol for prevention of DRPI. CONCLUSION: DRPIs pose a burden on patients in the ICU. Our study showed a DRPI prevalence comparable with other studies. Prevention strategies targeting DRPI should be included in ICU-specific pressure injury prevention guidelines or protocols.

Implementing best available evidence into practice for incontinence-associated dermatitis in Australia: A multisite multimethod study protocol.

AIMS: Incontinence-associated dermatitis (IAD) is an insidious and under-reported hospital-acquired complication which substantially impacts on patients' quality of life. A published international guideline and the Ghent Global IAD Categorisation Tool (GLOBIAD) outline the best available evidence for the optimal management of IAD. This study aims to implement theguideline and the GLOBIAD tool and evaluate the effect on IAD occurrences and sacral pressure injuries as well as patient, clinician and cost-effectiveness outcomes. MATERIALS AND METHODS: The study will employ a multi-method design across six hospitals in five health districts in Australia, and will be conducted in three phases (pre-implementation, implementation and post-implementation) over 19 months. Data collection will involve IAD and pressure injury prevalence audits for patient hospital admissions, focus groups with, and surveys of, clinicians, patient interviews, and collection of the cost of IAD hospital care and patient-related outcomes including quality of life. Eligible participants will be hospitalised adults over 18 years of age experiencing incontinence, and clinicians working in the study wards will be invited to participate in focus groups and surveys. CONCLUSION: The implementation of health district-wide evidence-based practices for IAD using a translational research approach that engages key stakeholders will allow the standardisation of IAD care that can potentially be applicable to a range of settings. Knowledge gained will inform future practice change in patient care and health service delivery and improve the quality of care for patients with IAD. Support at the hospital, state and national levels, coupled with a refined stakeholder-inclusive strategy, will enhance this project's success, sustainability and scalability beyond this existing project.

Protecting prone positioned patients from facial pressure ulcers using prophylactic dressings: A timely biomechanical analysis in the context of the COVID-19 pandemic.

Prone positioning is used for surgical access and recently in exponentially growing numbers of coronavirus disease 2019 patients who are ventilated prone. To reduce their facial pressure ulcer risk, prophylactic dressings can be used; however, the biomechanical efficacy of this intervention has not been studied yet. We, therefore, evaluated facial soft tissue exposures to sustained mechanical loads in a prone position, with versus without multi-layered silicone foam dressings applied as tissue protectors at the forehead and chin. We used an anatomically realistic validated finite element model of an adult male head to determine the contribution of the dressings to the alleviation of the sustained tissue loads. The application of the dressings considerably relieved the tissue exposures to loading. Specifically, with respect to the forehead, the application of a dressing resulted in 52% and 71% reductions in soft tissue exposures to effective stresses and strain energy densities, respectively. Likewise, a chin dressing lowered the soft tissue exposures to stresses and strain energy densities by 78% and 92%, respectively. While the surgical context is clear and there is a solid, relevant need for biomechanical information regarding prophylaxis for the prone positions, the projected consequences of the coronavirus pandemic make the present work more relevant than ever before.
