Exploring the effects of lateral pressure to the soft tissue of the buttocks during seating to preserve tissue perfusion.

AIM: Pressure-ulcer occurrence in the seated patient is understudied. Preventative devices have been developed and are prescribed commonly, but there is little quantitative evidence of their effectiveness. This study explores the concept of a lateral pressure device, a prevention device that applies pressure to the sides of the seated buttocks, to reduce the amount of tissue distortion and blood-vessel occlusion. It is hypothesized that this device will reduce deep tissue injury by reducing the pressure at the bone-muscle interface, as demonstrated computationally in previous research. This study aimed to use oximetry to investigate the efficacy of the device in maintaining transcutaneous gas tensions of the tissue as close to baseline as possible. METHODS: Oximetry electrodes were attached to participants' ischial tuberosity and greater trochanter for different amounts of lateral pressure. The amount of lateral pressure is a given percentage of the pressure due to the participants' underbody pressure. RESULTS: The results show that 50 % lateral pressure is sufficient to produce an improvement in participants' gas tensions at their ischial tuberosity, without negatively impacting the tissue at their greater trochanter, relative to the control of sitting with no application of lateral pressure. CONCLUSION: Despite a rudimentary prototype device design, and that participants each placed their own oximetry sensors, results support the application of lateral pressure as a method to maintain transcutaneous gas tensions. Further work should be carried out on a larger sample to consolidate these findings.

Pressure ulcer prevention for people with long-term neurological conditions (LTNCs) who self-manage care and live at home.

AIM: To develop a Theory of Change (ToC) pathway to facilitate the development of a multi-component intervention package supporting pressure Ulcer (PU) risk identification and management, in partnership with people with Long Term Neurological Conditions (LTNC) who self-manage care and live at home, their informal carers and PAs. METHODS: A participatory approach, with extensive input from those whose lives are the focus of the research, was used throughout the 4 interlinked work packages (WP): Iterative data analysis was undertaken with emerging findings from each WP informing subsequent stages of the study. FINDINGS: Overall, 74 participants contributed across the 4 WPs, incorporating 31 Service Users (SU), 8 carers, 9 Personal Assistants (PAs) and 26 professional stakeholders. We identified 8 key themes related to PU prevention, incorporating, learning, safe routines, third sector and peer support, navigating complex systems, adapting and reacting to change, perceptions of risk, risk negotiation and supporting roles. The findings indicate systemic and professional barriers which hamper people's ability to self-care and seek help. CONCLUSIONS: The study highlights the complexities and impact of managing PU prevention activities at home for people with LTNC and areas of learning for health professionals and systems. By understanding these complexities we developed a systems map, identified resource requirements and illustrated a Theory of Change (ToC) pathway, to underpin future work to develop and user test an interactive, multi-component intervention.

Peer support as pressure ulcer prevention strategy in special school learners with paraplegia.

Background: Adults with spinal cord injuries perceived peer support as beneficial in preventing secondary health conditions, but the role of peer support among adolescent learners with paraplegia in special schools is still unknown. Objectives: To explore the perspectives of current and previous learners with paraplegia on peer support to prevent pressure ulcers in a special school. Method: A qualitative, exploratory, descriptive study design was used. The authors conducted 12 semi-structured telephonic, audio-recorded interviews and a focus group discussion with current and previous learners with paraplegia attending a special school. The interviews were transcribed verbatim and translated, and data were organised using the Nvivo-12 Pro program. Through conducting an inductive thematic analysis categories, sub-themes and themes were identified from the participants' narratives. Results: The participants' perspectives included positive and challenging aspects of peer support reflected in four sub-themes: group-based support, individual peer mentoring, challenges with peer support and the roles of the school physiotherapist regarding peer support. Conclusion: Learners saw peer support as a crucial strategy in preventing and reducing pressure ulcers. Establishing a peer support system with group and individual components in special schools could be a game-changer to end pressure ulcers among learners with paraplegia and ensure better health and educational outcomes. Clinical implications: Physiotherapists in special schools should support peer support initiatives among learners with paraplegia to ensure successful pressure ulcer prevention.

A pilot study for testing feasibility and preliminary influence of early intervention using text messaging for pressure ulcer prevention in individuals with spinal cord injury.

BACKGROUND: This pilot study assessed text messaging as an early intervention for preventing pressure ulcers (PrUs) in individuals with spinal cord injury (SCI) post-hospital discharge. METHOD: Thirty-nine wheelchair-users discharged after acquiring a SCI, underwent randomisation into an intervention group (n = 20) with text messages and a control group (n = 19). All participants received standard post-discharge care and completed a skincare questionnaire before and 6-month after discharge. Primary outcomes included feasibility and acceptability of early intervention using text messaging, alongside performance, concordance, and attitudes toward skincare. Secondary outcomes measured perception and the incidence of PrUs. RESULTS: Baseline demographics were comparable between the intervention and control groups. Eight of 20 participants completed 6-month follow-up questionnaires in the intervention group, six participants completed the 6-month questionnaires in the control group,. Participants expressed high satisfaction with text messages, understanding of content, and increased confidence in preventing PrUs. At 6-month post-discharge, the intervention group showed improved prevention practices, heightened awareness of PrU risks, and increased perceived importance of prevention, which were not observed in the control group. However, there were no significant differences in PrU incidence, possibly due to the small sample size and short follow-up. CONCLUSION: The study demonstrates that using text messaging as an early intervention for PrU prevention in individuals with SCI is feasible and well-received. Preliminary results suggest a positive impact on participants' attitudes and practices, indicating the potential of text messaging to reduce PrU incidence. However, further research with larger samples and extended follow-up is crucial to validate these promising initial findings.

In vivo mechanical response of thigh soft tissues under compression: A two-layer model allows an improved representation of the local tissue kinematics.

Biomechanical parameters have the potential to be used as physical markers for prevention and diagnosis. Finite Element Analysis (FEA) is a widely used tool to evaluate these parameters in vivo. However, the development of clinically relevant FEA requires personalisation of the geometry, boundary conditions, and constitutive parameters. This contribution focuses on the characterisation of mechanical properties in vivo which remains a significant challenge for the community. The aim of this retrospective study is to evaluate the sensitivity of the computed elastic parameters (shear modulus of fat and muscle tissues) derived by inverse analysis as a function of the geometrical modelling assumption (homogenised monolayer vs bilayer) and the formulation of the cost function. The methodology presented here proposes to extract the experimental force-displacement response for each tissue layer (muscle and fat) and construct the associated Finite Element Model for each volunteer, based on data previously collected in our group (N = 7 volunteers) as reported in (Fougeron et al., 2020). The sensitivity analysis indicates that the choice of the cost function has minimal impact on the topology of the response surface in the parametric space. Each surface displays a valley of parameters that minimises the cost function. The constitutive properties of the thigh (reported as median ± interquartile range) were determined to be (µ=198±322Pa,α=37) for the monolayer and (µmuscle=1675±1127Pa,αmuscle=22±14,µfat=537±1131Pa,αfat=32±7) for the bilayer. A comparison of the homogenised monolayer and bilayer models showed that adding a layer reduces the error on the local force displacement curves, increasing the accuracy of the local kinematics of soft tissues during indentation. This allows for an increased understanding of load transmission in soft tissue. The comparison of the two models in terms of strains indicates that the modelling choice significantly influences the localization of maximal compressive strains. These results support the idea that the biomechanical community should conduct further work to develop reliable methodologies for estimating in vivo strain in soft tissue.

Insights into pressure injury prevention: Assessing the knowledge, attitudes, and practices of Palestinian nursing students.

AIM: To assess the knowledge, attitudes, and practices of Palestinian nursing students towards pressure injury prevention. MATERIALS AND METHODS: A descriptive cross-sectional study was conducted with 455 nursing students recruited from Arab American University-Palestine, employing a total population sample. Data collection forms include socio-demographic information, the Pressure Ulcer Knowledge Assessment Tool, Attitude towards Pressure Ulcer Prevention Instrument and Pressure Injury Preventive Practices scale. RESULTS: The study found that students had a mean knowledge score of 54% (14.04/26), a positive attitude score of 75.8% (39.42/52), and demonstrated a fair level of practice 75.3% (30.12/40). Significant differences were observed in the Knowledge, Attitude, and Practice total scores, linked to academic year, clinical experience, and the number of attended departments during clinical training (p < 0.001). Additionally, weak but significant positive relationships were found between practice and attitude scores (r = 0.303, p < 0.001), practice and knowledge score (r = 0.211, p < 0.001), and a moderate positive significant relationship between knowledge and attitude scores (r = 0.567, p < 0.001). CONCLUSION: The study revealed insufficient knowledge, positive attitudes, and somewhat unsafe practices among nursing students regarding pressure injury prevention. It highlights the need for specific revisions in the nursing curriculum. Improvements can be achieved through detailed coverage in classrooms and laboratories, integrating simulation methods. Additionally, ensuring that students gain adequate experiences in clinical units, with a specific emphasis on pressure injury prevention, is crucial for improving students' capability and contribute to better pressure injury management.

Prediction of tissue deformation based on mechanical and physiological factors in the prone position during surgery.

AIM: This study aimed to predict tissue deformation based on the pressure applied while lying in the prone position and physiological factors. METHODS: Healthy volunteers were instructed to lie on mattresses of four different hardness levels (50, 87.5, 175, and 262.5 N). The order in which the mattresses were used was randomized per participant. Pressure at the iliac crests was measured using a pressure mapping sensor sheet. Participants were placed in the prone position for 10 min, with pressure data used from the latter 5 min. For the tissue deformation at the iliac crests, our previous study data were used. Multiple regression analysis was used to identify predictive mechanical and physiological factors. RESULTS: The distance between the left and right greater trochanters, maximum interface pressure and age were significant predictors for compression of the skin and soft tissue. Significant predictors of internal soft tissue displacement were the distances between the left and right anterior superior iliac spines and greater trochanters. No factors predicted skin surface displacement. CONCLUSIONS: Our study provided predictive factors that may be measured easily in a clinical setting to reduce the risk of pressure ulcers during surgery in the prone position.

The comparison of fluidized positioners and traditional gel pads for skin protection in neurosurgical patients undergoing lateral and prone positions: A retrospective analysis with propensity score matching method.

To compare fluidized positioners and gel pads for skin protection in neurosurgery patients placed in lateral and prone positions. It is one of the major challenges that operating room nurses face in protecting the skin during the long duration of neurosurgery. Currently, there are increasing tools available to protect the skin under pressure, and various tools practice well in the clinic. Fluidized positioners are newly emerging protective pads that have been clinically effective in protecting the skin, but no studies have compared them to previous pads. This is a retrospective cohort study. Data from 706 patients who underwent neurosurgery between January 2018 and December 2021 were systemically reviewed. Patients undergoing long-term neurosurgery in the neurosurgical lateral and prone positions were divided into two groups: fluidized positioners or gel pads. Propensity score matching (PSM) was performed for group balance (1:1 ratio) using the following baseline characteristics: age, gender, ASA (American Society of Anesthesiologists) classification, duration of surgery, surgical position and underlying disease. The incidence of decubitus, and length of stay (LOS) in the hospital were compared between the two groups. The results were obtained for 394 patients in the fluidized positioner group with a 3.8% incidence of pressure ulcers and 312 patients in the gel pad group with an 8% incidence of pressure ulcers, which were unbalanced in terms of gender, ASA, hypertension and diabetes data. After a PSM, patients were compared in terms of pressure ulcer incidence (3.7% vs. 7.8%, p = 0.034) and LOS (22.35 vs. 25.65 days, p < 0.001). Fluidized positioners can effectively reduce the incidence of pressure injury in lateral and prone positions of neurosurgery. The results of this study may contribute to the development of policies to prevent the development of pressure ulcers during neurosurgical procedures.

Organizational development and management factors involved in the prevention and effective therapy of pressure ulcers: The results of the national survey conducted among Hungarian public hospitals.

The prevention of pressure ulcer (PU) or pressure injury (PI) wounds is of public health importance in developed countries, including Hungary. The study aimed to assess the PU/PI prevention and care practices of Hungarian public hospitals and identify organizational and management factors. In 2022, a national, questionnaire-based survey of inpatient institutions relevant to PU/PI care was conducted, providing a picture of the practices of 86 hospitals for the year 2019. The questionnaire was processed using descriptive statistics and regression analysis. The survey results show that good practices in Hungary are isolated, the reporting system is inhomogeneous, and documentation is not uniform across our institutional system. Of the 86 institutions, 71.0% operate a PU prevention team, 64.0% use prophylactic dressings, and 88.3% use an anti-decubitus mattress, with an average ratio of 26.1% to the number of beds. Less than half of the institutions reported the incidence of hospital acquired pressure injuries (HAPIs). In this sample, we found no significant association between hospital type and hospital size with the incidence of full-thickness HAPIs (stage III and IV wounds). Developing a comprehensive PU/PI reporting system and updating the national PU/PI prevention and care guidelines are essential in Hungary.

Psychosocial factors impacting community-based pressure ulcer prevention: A systematic review.

BACKGROUND: Pressure ulcers are a major health concern. They have a significant impact on the healthcare system and individuals, reducing quality of life across several domains. In community settings, self-management behaviours are central to their prevention. However, adherence with pressure ulcer prevention guidelines remains low, with little evidence guiding the relationship between patients and healthcare professionals to establish a concordant partnership. OBJECTIVE: To synthesise evidence on factors contributing to community-based pressure ulcer prevention using the Theoretical Domains Framework and the Capability, Opportunity, Motivation, Behaviour (COM-B) model of behaviour. DESIGN: Mixed methods systematic review and narrative synthesis. METHOD: Systematic searches were conducted in the CINAHL, Cochrane, EMBASE, PsycINFO, PubMed, Scopus, and Web of Science databases on 14th December 2022. Studies were eligible if they contained data on the factors associated with adherence and concordance with pressure ulcer prevention guidelines in the community for patients, caregivers, and healthcare professionals. Methodological quality was assessed using the Hawker tool. Findings were synthesised using the Theoretical Domains Framework. The resulting themes were mapped onto the Capability, Opportunity, Motivation, Behaviour (COM-B) model. RESULTS: Thirty studies were included in the review, including quantitative, qualitative, and mixed methods research. The synthesis identified 12 of the 14 Theoretical Domains Framework domains, with knowledge, social influences, beliefs about consequences, and beliefs about capabilities the most prevalent. Although knowledge appears to be an important contributor to adherence with prevention guidelines, knowledge alone does not appear sufficient to achieve concordance. A concordant relationship was facilitated by healthcare professionals' knowledge, motivation to work alongside patients and their priorities, and interpersonal skills to build rapport and trust, whilst barriers included lack of healthcare professional skills to navigate sensitive issues, paternalistic views of patient compliance and organisational processes that impact building rapport. CONCLUSIONS: Several psychosocial factors may affect the ability to achieve concordance between individuals, caregivers and healthcare professionals with pressure ulcer prevention guidelines in the community. However, data regarding the efficacy of behaviour change interventions targeting these constructs is limited, with further research required to guide intervention development in this area.

The impact of healthcare assistant education on pressure ulcer prevention: a systematic review.

OBJECTIVE: To investigate the impact of education for healthcare assistants (HCAs) on their knowledge and skills in pressure ulcer (PU) prevention and on the incidence of PUs. A secondary aim was to evaluate education methodologies used in PU prevention programmes. METHOD: Using systematic review methodology, key databases were searched with no limitations on date of publication. The search was conducted in November 2021 using the following databases: CINAHL, Embase, Scopus, MEDLINE, Cochrane Wounds Group Specialist Register and Cochrane Central Register of Controlled Trials. Inclusion criteria focused on studies that employed the use of education as an intervention, delivered to HCAs in any setting. The PRISMA guidelines were followed. The methodological quality of the studies was evaluated using the Evidence-Based Librarianship (EBL) appraisal checklist. Data were analysed using narrative analysis and meta-analysis. RESULTS: The systematic search yielded an initial 449 records, of which 14 studies met the inclusion criteria. Outcome measures of HCA knowledge scores were reported in 11 (79%) studies. Outcome measures related to PU prevalence/incidence were reported in 11 (79%) studies. An increase in knowledge scores of HCAs post-educational intervention was reported in five (38%) studies. A significant reduction in PU prevalence/incidence rates post-educational intervention was reported in nine (64%) studies. CONCLUSION: This systematic review affirms the benefits of education of HCAs on their knowledge and skills of PU prevention, and on PU incidence. The results must be treated with caution due to quality appraisal issues of included studies.

A Multicenter Assessment of Nurses' Knowledge Regarding Pressure Ulcer Prevention in Intensive Care Units Utilizing the PUKAT 2.0.

Introduction: Pressure ulcer (PU) care is pivotal in the practice of nurses working in intensive care units (ICUs). Therefore, nurses must possess adequate knowledge about the potential risks leading to the development of PUs, as well as managing complications that worsen patient conditions. Objective: To evaluate the level of knowledge of ICU nurses concerning PU prevention in tertiary hospitals in Saudi Arabia. Methods: In this cross-sectional study, the researchers recruited 320 ICU nurses from four tertiary hospitals using convenience sampling. Nurses' knowledge regarding PU prevention was assessed using the revised and updated version of the Pressure Ulcer Knowledge Assessment Tool (PUKAT) 2.0. Data were collected between May and June 2022. The CROSS checklist was observed for reporting. Results: The mean scores of nurses' level of knowledge regarding PU prevention according to the themes of the revised and updated version of the PUKAT 2.0 were as follows-etiology: 62.81 ± 23.77; classification and observation: 50.86 ± 23.28; risk assessment: 31.19 ± 24.26; nutritious diet: 46.04 ± 25.96; prevention: 22.36 ± 12.41; and specific patient groups: 14.84 ± 22.88. Furthermore, the score for nurses' overall level of knowledge of PU prevention was 39.55 ± 8.84 out of 100, interpreted as low based on the 60% cutoff; the minimum knowledge score was 0. Notably, knowledge of PU etiology, classification, observation, and specific patient groups differed based on the hospital of affiliation. Interestingly, gender was the only demographic characteristic based on which nurses' knowledge regarding specific patient groups differed. Conclusion: This study identified insufficient knowledge among ICU nurses regarding PU prevention, which can lead to complications among patients. Simulation scenarios related to PU prevention and management will be an effective way to help nurses gain appropriate knowledge that can be applied in clinical practice.

Modelling the cost-effectiveness of subepidermal moisture measurement as part of a process of assessment and intervention to prevent hospital-acquired pressure ulcers.

Skin tissue assessment is traditionally used to identify early signs of pressure damage from changes observed at the skin surface. However, the early onset of tissue damage induced by pressure and shear forces is likely to be on soft tissues beneath the surface of the skin. Subepidermal moisture (SEM) is a biophysical marker for the detection of early and deep pressure-induced tissue damage. Measurement of SEM can detect early pressure ulcers up to 5 days before visible skin changes occur. The aim of this study was to evaluate the cost-effectiveness of SEM measurement compared with visual skin assessment (VSA). A decision-tree model was developed. Outcomes are the incidence of hospital-acquired pressure ulcers, quality-adjusted life-years (QALYs) and costs to the UK National Health Service. Costs are at 2020/21 prices. The effects of parameter uncertainty are tested in univariate and probabilistic sensitivity analysis. In a representative NHS acute hospital, the incremental cost of SEM assessment as an adjunct to VSA is -£8.99 per admission, and SEM assessment is expected to reduce the incidence of hospital-acquired pressure ulcers by 21.1%, reduce NHS costs and lead to a gain of 3.634 QALYs. The probability of cost-effectiveness at a threshold of £30 000 per quality-adjusted life year is 61.84%. Pathways that include SEM assessment make it possible to implement early and anatomy-specific interventions which have the potential to improve the effectiveness of pressure ulcer prevention and reduce healthcare costs.

Interventions, stakeholders, and organisation related to pressure ulcer prevention for individuals with spinal cord injuries in transition from hospital to home - A scoping review.

STUDY DESIGN: Scoping review. AIM OF THE STUDY: To obtain an overview of initiatives, organisational components, and stakeholders' perspectives on PU prevention in transitional care. METHODS: Scoping review searching the databases: MEDLINE, EMBASE), CINAHL, Cochrane Library, Web of Science, and SCOPUS in May 2022. Inclusion of English-written research on pressure ulcer prevention in adult people with spinal cord injury in transition from hospital or rehabilitation centre to the home care environment. RESULTS: Fifteen studies of different types are included in this study: six qualitative studies, four randomized controlled trials, three cohort studies, one cross-sectional study and an interventional study. The included studies are relatively low-level evidence but of acceptable quality. CONCLUSION: Continuous tailored education and information about PU prevention and follow-up services are essential components in preventing PUs and rehabilitating people with SCI. The complexity of SCI requires adaptations, equipment and access to specialist care and treatment after discharge. However, there is a discrepancy between the international recommendations, the perceived needs, and the delivered healthcare services. The consequences are a lower quality of life and a higher risk of PUs for people with SCI.

A Comprehensive and Improved Definition for Hospital-Acquired Pressure Injury Classification Based on Electronic Health Records: Comparative Study.

BACKGROUND: Patients develop pressure injuries (PIs) in the hospital owing to low mobility, exposure to localized pressure, circulatory conditions, and other predisposing factors. Over 2.5 million Americans develop PIs annually. The Center for Medicare and Medicaid considers hospital-acquired PIs (HAPIs) as the most frequent preventable event, and they are the second most common claim in lawsuits. With the growing use of electronic health records (EHRs) in hospitals, an opportunity exists to build machine learning models to identify and predict HAPI rather than relying on occasional manual assessments by human experts. However, accurate computational models rely on high-quality HAPI data labels. Unfortunately, the different data sources within EHRs can provide conflicting information on HAPI occurrence in the same patient. Furthermore, the existing definitions of HAPI disagree with each other, even within the same patient population. The inconsistent criteria make it impossible to benchmark machine learning methods to predict HAPI. OBJECTIVE: The objective of this project was threefold. We aimed to identify discrepancies in HAPI sources within EHRs, to develop a comprehensive definition for HAPI classification using data from all EHR sources, and to illustrate the importance of an improved HAPI definition. METHODS: We assessed the congruence among HAPI occurrences documented in clinical notes, diagnosis codes, procedure codes, and chart events from the Medical Information Mart for Intensive Care III database. We analyzed the criteria used for the 3 existing HAPI definitions and their adherence to the regulatory guidelines. We proposed the Emory HAPI (EHAPI), which is an improved and more comprehensive HAPI definition. We then evaluated the importance of the labels in training a HAPI classification model using tree-based and sequential neural network classifiers. RESULTS: We illustrate the complexity of defining HAPI, with <13% of hospital stays having at least 3 PI indications documented across 4 data sources. Although chart events were the most common indicator, it was the only PI documentation for >49% of the stays. We demonstrate a lack of congruence across existing HAPI definitions and EHAPI, with only 219 stays having a consensus positive label. Our analysis highlights the importance of our improved HAPI definition, with classifiers trained using our labels outperforming others on a small manually labeled set from nurse annotators and a consensus set in which all definitions agreed on the label. CONCLUSIONS: Standardized HAPI definitions are important for accurately assessing HAPI nursing quality metric and determining HAPI incidence for preventive measures. We demonstrate the complexity of defining an occurrence of HAPI, given the conflicting and incomplete EHR data. Our EHAPI definition has favorable properties, making it a suitable candidate for HAPI classification tasks.

Inter-rater reliability of descriptors for the classification of mucosal pressure injury: A prospective cross-sectional study.

BACKGROUND: Mucosal pressure injuries (PIs) are usually caused by pressure from essential medical devices. There is no universally accepted criterion for assessment, monitoring, or reporting mucosal PI. Reliable descriptors are vital to benchmark the frequency and severity of this hospital-acquired complication. OBJECTIVES: The objective of this study was to determine whether modified Reaper Oral Mucosa Pressure Injury Scale (ROMPIS) descriptors improved the reliability of mucosal PI assessment. Secondary aims were to explore nurses' knowledge of and attitudes toward mucosal PI. METHODS: A prospective cross-sectional survey was distributed to nurses from two tertiary affiliated intensive care units via REDCap® to capture demographic data, knowledge, attitudes, and inter-rater reliability (IRR) measures. Nurses were randomised at a 1:1 ratio to original or modified ROMPIS descriptors and classified 12 images of mucosal PI. IRR was assessed using percentage agreement, Fleiss' kappa, and intraclass correlation coefficients. RESULTS: The survey response rate was 20.9% (n = 98/468), with 73.5% (n = 72/98) completing IRR measures. Agreement was higher with modified (75%) than original ROMPIS descriptors (69.4%). IRR was fair for the original (κ = 0.30, 95% confidence interval [CI] [0.28, 0.33], z 26.5, p < 0.001) and modified ROMPIS (κ = 0.29, 95% CI [0.26, 0.31], z 25.0, p < 0.001). Intraclass correlation coefficient findings indicated ratings were inconsistent for the original (0.33, 95% CI [0.18, 0.59], F 18.8 (11 df), p < 0.001) and modified ROMPIS (0.31, 95% CI [0.17, 0.57], F 17.6 (11 df), p < 0.001). PI-specific education and risk factor recognition were common. CONCLUSION: Modified descriptors had marginally better agreement. Participants understand management and prevention but need to strengthen their perceived capacity for mucosal PI risk assessment. This work provides a foundation for future benchmarking and a platform from which further research to refine and test descriptors specific to mucosal PI can be generated.

The knowledge and attitudes regarding pressure ulcer prevention among healthcare support workers in the UK: A cross-sectional study.

BACKGROUND: Pressure ulcers cause significant, detrimental effects on personal wellbeing. They represent a serious health and social care burden. Nurses and those working in support roles are primarily accountable for preventing pressure ulcers. Healthcare support workers are an expanding group of key workers in the UK. OBJECTIVE: To examine healthcare support workers' knowledge and attitudes regarding pressure ulcer prevention. METHODS: A cross-sectional study was conducted from December 2020 to June 2021, using Knowledge and Attitudes toward Pressure Ulcer Prevention Assessment Tool. RESULTS: A total of 164 participants completed the questionnaire fully. A low mean knowledge score of 0.42 ± 0.14, but a positive attitude score of 0.76 ± 0.10 per item were reported. The weakest areas of knowledge include aetiology, risk assessment and addressing pressure-reducing interventions for patients at risk. Higher mean scores per item in knowledge of pressure ulcer prevention were reported in participants working in acute hospital wards and nursing homes (0.468 ± 0.15, 0.47 ± 0.08 respectively) than those in other settings (p < 0.05). Participants working in primary care scored lowest (0.33 ± 0.12). The scores of participants with more positive attitudes towards pressure ulcer prevention significantly correlated with higher score of knowledge (p < 0.005). CONCLUSION: While positive attitudes towards pressure ulcer prevention exist among healthcare support workers, this is overshadowed by significant knowledge deficits. Findings highlight the importance of continuing structured education for support workers across both acute and community settings. A future national survey and interventional study are needed to examine support workers' pressure ulcer knowledge and to inform a national continuous education strategy.

Physiotherapists' knowledge on pressure ulcer prevention.

Pressure ulcers can develop in bedridden or immobile patients which physiotherapists frequently encounter. Although physiotherapists receive training for preventing pressure ulcers, there is limited evidence of physiotherapists' knowledge level. Our study evaluated physiotherapists' pressure ulcer prevention knowledge. The level of knowledge for pressure ulcer prevention was inquired with the Turkish version of the Pressure Ulcer Prevention Knowledge Assessment Instrument (PUPKAI-T). Two hundred and sixty-five physiotherapists participated in our study. The median PUPKAI-T total score ranged from 8 to 21. Only two physiotherapists (0.8%) got good points from the questionnaire. The highest score was Nutrition (Theme 4; 59.2%), and the lowest score belonged to the contact preventive interventions that reduce pressure/shearing (Theme 5; 26.7%). The question with the lowest success rate was the positioning question of Theme 5 (Question 2; 12.5%). In our study, physiotherapists' pressure ulcer prevention knowledge was evaluated with a relatively high number of participants compared to the literature. These results brought to mind that training programs that specifically emphasise techniques to prevent pressure ulcers and positioning manoeuvres to be organised increase the knowledge level of physiotherapists.

Prevention of pressure injuries during military aeromedical evacuation or prolonged field care: A randomized trial.

BACKGROUND: During military aeromedical evacuation (AE) and prolonged field care (PFC), casualties are at increased pressure injury (PI) risk. Operational PI mitigation strategies research is limited. PURPOSE: Using multiple factors, this study examined Mepilex/LiquiCell effects on PI risk under simulated AE/PFC. METHODS: Healthy adults were stratified by body fat (%) and randomized to six groups on three surfaces. Set A: Warrior Evacuation Litter Pad (WELP) with/without Mepilex; Set B: Vacuum Spine Board (VSB) with/without Mepilex; Set C: Talon litter with/without LiquiCell. Two hours supine (loaded) was needed. OUTCOMES: Sacral skin transcutaneous tissue oxygen (TcPO2), temperature, moisture, interface pressure, interleukin-1α/Total Protein. FINDINGS: 54 participants. Sets A/B: No Mepilex effects; temperature increased 2.5°C. Set C: No LiquiCell effects. Significant ΔTcPO2 (unloaded-loaded), with 100% impaired perfusion; temperature increased 1.2°C. DISCUSSION: Multiple risk factors for PI mitigating strategies must consider. Talon with increased pressure/impaired perfusion but smaller temperature/moisture changes; WELP/VSB with increased temperature/moisture but lower pressure/adequate perfusion.

Repositioning mattress: how a lateral tilt position reshapes the prevention of pressure ulcers in bedridden patients.

Pressure ulcers have been part of tissue damage without effectiveness in medical, surgical, and intensive care units. This study aims to focus on developing lateral tilt positions for effective pressure ulcer relief for bedridden patients. A repositioning mattress was placed in the side-lying left lateral tilt position (15°, 30°, 45°), sheering (0.680, 1.323, 1.870), interface pressure (2.550, 2.290, 2.830), and placed at 1.5 m long piece of polyethylene rubber. The design strength was set at 6000 N and 2100 mm x 1105 mm (σt,0,d = 42, σc,0,d = 34). The design shows the greatest supine position at 30°, 1.323, 2.290, pressure load (Δp0 = 1.125 (1820) ≈ 2050 psi, Δp3000 = 1.125 (620) ≈ 700 psi), tensile stress (σt,0,d (MPa) = 42), compressive stress (σc,0,d (MPa) = 34), and FOS (σt,0,d = 42, σc,0,d = 34). The factor of safety illustrated that the 30° lateral tilt position is more consistent in repositioning for pressure ulcer prevention compared to the supine-to-tilt region. Further, an application of repositioning mattresses was developed to test in bedridden patients with tissue ulcers in nursing homes.
