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. Int Wound J 2024; 21:e14662. [PMID: 38402555 PMCID: PMC10830910 DOI: 10.1111/iwj.14662] [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: 12/12/2023] [Revised: 12/24/2023] [Accepted: 12/29/2023] [Indexed: 02/26/2024] Open
Abstract
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.

Modelling the cost-effectiveness of subepidermal moisture measurement as part of a process of assessment and intervention to prevent hospital-acquired pressure ulcers. Int Wound J 2023; 20:2688-2699. [PMID: 37203247 PMCID: PMC10410331 DOI: 10.1111/iwj.14143] [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: 12/08/2022] [Revised: 02/17/2023] [Accepted: 02/20/2023] [Indexed: 05/20/2023] Open
Abstract
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.

Abstract
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.

Abstract
The purpose of this study was to examine nurses' perceptions of the smart mattress equipped with Internet of things, which are incorporated into patients' beds. In addition, their concerns and suggestions about smart mattress were explored. A total of 349 nurses in a tertiary hospital participated in a cross-sectional survey. Data were collected using questionnaires. Descriptive statistical analysis was used for survey data, whereas content analysis was used for qualitative data from open-ended questions. The participants' intention to accept the smart mattresses was 12.5 (SD, 1.73) on average, indicating a high level of acceptance. The participants expected the smart mattresses to decrease their physical work burden, improve work efficiency, and prevent pressure ulcers. However, they were concerned about an increase in other aspects of their workload and in patient safety problems due to false alarms, inaccuracies, and malfunctions of the device. Nurses suggested various features that can be integrated into smart mattress. It is critical to address nurses' perceptions, expectations, and concerns during the conceptual and developmental stage of new technology in order to improve the usability, acceptance, and adoption of smart mattresses and other new innovations in hospital settings.

A Comprehensive and Improved Definition for Hospital-Acquired Pressure Injury Classification Based on Electronic Health Records: Comparative Study. JMIR Med Inform 2023; 11:e40672. [PMID: 36649481 PMCID: PMC9999254 DOI: 10.2196/40672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 12/24/2022] [Accepted: 01/14/2023] [Indexed: 01/19/2023] Open
Abstract
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.

A Multicenter Assessment of Nurses' Knowledge Regarding Pressure Ulcer Prevention in Intensive Care Units Utilizing the PUKAT 2.0. SAGE Open Nurs 2023; 9:23779608231177790. [PMID: 37273548 PMCID: PMC10233595 DOI: 10.1177/23779608231177790] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 05/03/2023] [Accepted: 05/05/2023] [Indexed: 06/06/2023] Open
Abstract
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.

Abstract
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.

Relationship between mattress internal air pressure and interface pressure distribution in the lateral position. Int Wound J 2022; 19:2115-2123.

Abstract
Previous research shows that maximum interface pressure increases when the patient is lying in the lateral position. However, it was unclear whether it was better to increase or decrease the internal air pressure to reduce the maximum interface pressure in the lateral position; thus, this study investigated this issue. In this study, we investigated the change in pressure redistribution because of the difference in internal air pressure between the supine and lateral positions on an active air mattress for pressure ulcer prevention management. Each participant's five internal air pressure values served as the independent variables. The interface pressure on the active air mattress was measured for 20 minutes. The sacral left iliac crest and left greater trochanteric interface pressures were measured using a portable pressure-measuring device. When seven of the 10 participants switched from the supine position to the left lateral position, there was a decrease in the maximum interface pressure as the internal air pressure increased. The maximum interface pressure in the greater trochanter in the lateral position was twice that in the sacral region in the supine position. These results show that increasing the internal air pressure in the lateral position might help reduce the maximum interface pressure.

Abstract
Pressure ulcers (PUs) negatively affect quality of life (QoL) and cause problems for patients, such as pain, distress and often specific difficulties with treatments used to manage the wound. Thus, it is important to implement appropriate prevention strategies in order to achieve high-quality care, thereby reducing the burden of PUs on patients, the healthcare system and society as a whole. PU development arises due to the adverse effects of pressure, shear, friction and moisture at the skin/surface interface. Preventive interventions typically include risk assessment, reducing pressure and minimising shear and friction. More recently, certain wound dressings, as a potential additional protective strategy for preventing PUs, have been introduced. This review explores the mechanisms of action of dressings for preventing PUs. Findings from the review indicate that decreasing frictional forces transmitted to the patient's skin is achieved by use of a dressing with an outer surface made from a low friction material. Furthermore, the ability of dressings to absorb and redistribute shear forces through good adhesion to the skin, high loft and lateral movement of the dressing layers is important in reducing shear forces. This is achieved when the dressing reduces pressure transmitted to the patient's tissues by the propriety of high loft/thickness and padding that allows a degree of cushioning of bony prominences. Further, dressings may reduce humidity at the skin/dressing interface, i.e., the dressing is absorbent and/or permits moisture to evaporate quickly. As part of an established PU prevention protocol, dressings may help decrease PU incidence.

Consistent practice for pressure ulcer prevention in long-term older people care: A quasi-experimental intervention study. Scand J Caring Sci 2020; 35:962-978. [PMID: 33164226 DOI: 10.1111/scs.12917] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 08/21/2020] [Accepted: 09/28/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Consistent practice, an agreed clinical practice based on evidence, has been considered as a base for effective provision of quality and safety of care. As a result, patients have an equal quality of care regardless of the organisation or worker. However, despite the international guidelines, pressure ulcer prevention practices vary in long-term older people care. AIM To develop, implement and evaluate the impact of renewed, consistent practice for pressure ulcer prevention, in long-term older people care. DESIGN A quasi-experimental intervention study. METHODS Two long-term older people care facilities chosen with convenience sampling were randomly allocated to intervention or comparison group. Registered and practical nurses, in total 141/112, participated in the study. The renewed consistent practice based on international guidelines for pressure ulcer prevention was developed and implemented using the Operational Model for Evidence-Based Practices (OMEBP). Frequencies and agreement of PU prevention practices in line with international guidelines in the care facilities were measured using the PUPreP instrument. RESULTS In the intervention facility, improvement in line with international guidelines was seen in the frequency of PU prevention practices in risk assessment, nutrition, pressure-relieving devices and documentation. Furthermore, improvement was seen in the intervention facility in all six areas of agreement on practices. CONCLUSIONS The results of this study support the implementation of PU prevention guidelines in long-term older people care (LOPC) and more widely in healthcare settings for older people to promote consistent practice, and safety and equal quality of care.

The subepidermal moisture scanner: the technology explained. J Wound Care 2020.

Abstract
The objective of this article is to explain the biophysical principles underlying the design of the subepidermal moisture (SEM) scanner, commercially known as the 'SEM scanner'. We also describe the mode of operation of the SEM scanner in monitoring tissue health and detecting subtle abnormal changes in tissue physiology in patients and anatomical sites at a risk of a pressure ulcer (PU: also known as a pressure injury). The technology of the SEM scanner was approved last year for sales in the US by the Food and Drug Administration (FDA). The SEM scanner detects changes in fluid contents of human skin and subdermal tissues, to a tissue depth of several millimetres, by measuring 'capacitance', an electrical property of the locally examined tissue site to store electric charge. The capacitance of tissues, called 'biocapacitance', is strongly affected by the amount of fluid (water) in the tissue. When the first cells die in a forming PU, inflammatory signalling causes the permeability of blood vessel walls to increase and oedema to develop. Simply, the scanner detects the early appearance of oedema, which is called 'micro-oedema.' Calculation of a 'SEM-delta' value, which compares biocapacitance measurements, acquired across several tissue sites, some of which are healthy and others where the PU may evolve, eliminates potential effects of systemic changes in tissue fluid contents and provides a consistent quantitative measure of the tissue health conditions at the monitored anatomical site. Here, we describe SEM scanner technology, how it operates and has been laboratory tested (in computer simulations, in silico) before commercial launch. We explain why targeting the physical biomarker of oedema leads to the documented success of the SEM scanner in the multiple published clinical trials, proving its ability to early detect PUs that form under intact skin.

Abstract
OBJECTIVE To conduct a screening, skin examination and risk assessment of patients with pressure ulcers (PUs) in one Swedish county (inpatient, primary and community care) with follow-up after six months to investigate ulcer healing, frequency of amputation and mortality rate linked to preventive measures. METHOD The methodology recommended by the European Pressure Ulcer Advisory Panel was used. Screening, risk assessment and skin examination were performed during March 2017. The modified Norton scale was used to assess PU risk, with a score of ≤20 indicating presence of risk. A research questionnaire was used to document prevention and treatment. Follow-up was performed after six months, during September 2017. The same research questionnaire was used to capture the current situation of the patients, including ulcer healing, frequency of amputation, and mortality rate. RESULTS Screening covered 464 patients: 303 hospitalised, 68 in community care, and 93 in primary care. A total of 110 patients-55 at risk of PU and 55 with PUs, the majority of which were category 2-4 PUs-were included in the study. At follow-up, 67% were treated in community care, 32% in primary care, and 1% in hospital. Mortality rate for patients with PUs was 44%. Of the remaining 31 patients, 17 had unhealed PUs, 10 had healed PUs, two had undergone amputation, and complete follow-up data was missing in the remaining two patients. CONCLUSION These results reflect the complex situation of an aged and frail patient group, including a lack of preventive measures and follow-up routines in community and primary care.

Abstract
OBJECTIVE Patients hospitalised in the Burn Intensive Care Unit are at increased risk of pressure ulcers (PU; also known as pressure injuries). While effective methods exist to offload pressure from other areas, offloading the head is difficult, especially with facial or head burns. An increase in occipital PUs prompted a review of practices for offloading the head in the Burn Intensive Care Unit. METHOD A multidisciplinary team (MDT) of physicians, occupational therapists and nurses evaluated several devices used to prevent occipital PUs using a pressure mapping device. Pressure was measured using the SensorEdge Measure X device. The pressure mapping device provides a real-time graphic representation of pressure to the body area studied, in this case the occiput. In addition, the SensorEdge allows for numeric data to be exported to Excel format. RESULTS Our data showed that the occipital pressure was observed in our health volunteer using a fluidised gel positioner using pressure mapping. As a result of this we stopped using other pillows and went to exclusive use of the fluidised gel positioner. Reimplementation and consistent use of a fluidised gel positioner resulted in decreasing occipital PUs from nine to zero. CONCLUSION The use of a fluidised gel positioner should be considered in other critical care environments to reduce the prevalence of hospital acquired occipital PUs.

Abstract
Objective: The objective of this prospective clinical study was to validate two prototype pressure ulcer monitoring platform (PUMP) devices, (PUMP1 and PUMP2), to promote optimal bed repositioning of hospitalized patients to prevent pressure ulcers (PUs). Approach: PUMP1 was a wearable electronic device attached to the patient gown with no skin contact. PUMP2 was a set of four identical electronic devices placed under the patient's bed wheels. A video camera recorded events in the patient room while measurements from the PUMP devices were correlated with true patient repositioning activity. The performance of these PUMP devices developed by our research team were evaluated and compared by both clinicians and engineers. Results: Ten mobility-restricted patients were enrolled into the study. Repositioning movement was recorded by both PUMP devices for 10 ± 2 h and corroborated with video capture. One hundred thirty-seven movements in total were detected by both PUMP1 and PUMP2 over 105 h of capture. Two false positives were detected by the sensors and 11 movements were missed by the sensors. PUMP1 and PUMP2 never conflicted in data collection. Innovation: The presented study evaluated two different sensors' abilities to capture accurate patient repositioning to eventually prevent PU formation. Importantly, detection of patient motion was completed without contact to patient skin. Conclusion: The clinical study demonstrated successful capture of patient repositioning movement by both PUMP1 and PUMP2 devices with 85% reliability, 2 false positives, and 11 missed movements. In future studies, the PUMP devices will be combined with a SMS-based mobile phone alert system to improve caregiver repositioning behavior.

Abstract
OBJECTIVE Despite the availability of high-quality clinical practice guidelines, pressure ulcers (PU) continue to develop among older adults in acute and long-term health-care facilities. Except during acute medical crisis or near end-of-life, most PUs are preventable and their development is a health-care quality indicator. The aim of this study was to understand which factors facilitate pressure ulcer prevention among adults over 65 years-of-age receiving care in health-care facilities. METHOD A critical literature review from three scholarly databases examined components of organisational culture associated with PU prevention. Research papers involving adults >65 years-of-age who were admitted to acute and long-term health-care facilities with PU prevention programmes between 2010 and 2017 were included. A secondary manual search included literature discussing health-care organisational culture, with a total of 41 articles reviewed. RESULTS Based on a synthesis of this literature, the Factors Facilitating Pressure Ulcer Prevention Model was developed to depict five multilevel factors for PU prevention among older adults in health-care facilities. These five factors are: senior leadership, education, ongoing quality improvement, clinical practice, and unit level champions. CONCLUSION Ongoing prioritisation of these factors sustains PU prevention and assists health-care facilities to redefine their culture, expand education programmes, and promote accountability to improve health outcomes of older adults receiving care.

Abstract
OBJECTIVE Hospital-acquired pressure ulcers (HAPUs) remain a problem despite numerous prevention initiatives. To understand why, it is necessary to know health professionals' perceptions regarding the importance of prevention, and the usability of current initiatives. We hypothesised that positive perceptions of existing initiatives would not be correlated with low HAPU prevalence, and that health professionals would perceive the initiatives to have a low usability. METHOD A two-part, online survey was developed and distributed electronically to nurses, in-training physicians and attending physicians, across all inpatient and perioperative departments of an academic hospital. Part one of the survey was the Agency for Healthcare Research and Quality (AHRQ) Staff Attitude Scale on beliefs regarding PU prevention; part two was additional questions on the usability of existing preventative initiatives. The results of the survey were compared with quarterly HAPU prevalence data by hospital unit. RESULTS In total, 839 health professionals completed the survey (579 nurses, 131 residents, 119 attending physicians). The mean score for the AHRQ survey was 42.5 (≥40 denoting positive perceptions). There was a moderate correlation between AHRQ scores and prevalence of HAPUs (r=-0.60, p=0.402). For usability, repositioning was felt to be the most effective intervention (mean: 4.54, standard deviation (SD): 0.64), while educational posters were felt to be the least effective (mean: 3.31, SD: 0.99). Respondents generally rated satisfaction much lower, with no single initiative significantly better than the others (range: 3.21-3.79). Perceived effectiveness and satisfaction were all positively correlated. CONCLUSION High HAPU prevalence, despite position perceptions, suggests that prevention methods are not as effective as thought, or they are not being used as widely as they should. Further research should take advantage of positive attitudes by prospectively investigating the usability of novel interventions.

Sodium pyruvate pre-treatment prevents cell death due to localised, damaging mechanical strains in the context of pressure ulcers. Int Wound J 2019; 16:1153-1163. [PMID: 31407500 DOI: 10.1111/iwj.13173] [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: 05/06/2019] [Accepted: 07/26/2019] [Indexed: 12/27/2022] Open
Abstract
We demonstrate sodium pyruvate (NaPy) pre-treatment as a successful approach for pressure ulcer (PU) prevention by averting their aetiological origin-cell-level damage and death by large, sustained mechanical loads. We evaluated the NaPy pre-treatment effect on permeability changes in the cell's plasma membrane (PM) following application of in vitro damaging-level strains. Fibroblasts or myoblasts, respectively, models for superficial or deep-tissue damage were grown in 0 or 1 mM NaPy, emulating typical physiological or cell culture conditions. Cells were pre-treated for 4 hours with 0 to 5 mM NaPy prior to 3-hour sustained, damaging-level loads (12% strain). PM permeability was quantified by the cell uptake of small (4 kDa), fluorescent dextran compared with unstrained control using fluorescence-activated cell sorting (FACS). Pre-treatment with 1 mM, and especially 5 mM, NaPy significantly reduces damage to PM integrity. Long-term NaPy pre-exposure can improve protective treatment, affecting fibroblasts and myoblasts differently. Pre-treating with NaPy, a natural cell metabolite, allows cells under damaging-level mechanical loads to maintain their PM integrity, that is, to avoid loss of homeostasis and inevitable, eventual cell death, by preventing initial, microscale stages of PU formation. This pre-treatment may be applied prior to planned periods of immobility, for example, planned surgery or transport, to prolong safe time in a position by preventing initial cell damage that can cascade and lead to PU formation.

Preventing pressure ulcers in nursing homes using a care bundle: A feasibility study. HEALTH & SOCIAL CARE IN THE COMMUNITY 2019; 27:e417-e427. [PMID: 30919525 PMCID: PMC6618244 DOI: 10.1111/hsc.12742] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 01/16/2019] [Accepted: 02/18/2019] [Indexed: 06/03/2023]
Abstract
Pressure ulcers can be painful and negatively affect health-related quality of life and healthcare costs. Many people living in nursing homes are at risk of developing a pressure ulcer. Nursing home staff, tissue viability nurses and researchers have co-designed the first theory and evidence-informed care bundle specifically for nursing homes, which consists of three prevention practices (skin inspection, support surfaces, repositioning) and a range of behaviour change techniques to promote these practices. We conducted a mixed methods feasibility study of the use of this care bundle in one nursing home in the North of England using an uncontrolled, before-and-after study design. We collected quantitative data on pressure ulcer prevention behaviours of the nursing home staff and pressure ulcer incidence rates for 5 weeks prior to implementing the bundle. Data collection continued for a further 9 weeks during the bundle implementation phase. We explored adherence to the bundle and participants' experiences of using it. The Conceptual Framework for Implementation Fidelity and the Theoretical Domains Framework informed the semi-structured interviews. Quantitative and qualitative data were analysed using descriptive statistics and deductive framework analysis respectively. We collected data for 462 resident bed days prior to implementing the bundle; five new pressure ulcers were recorded and repositioning was the only documented pressure ulcer prevention behaviour. We collected data for 1,181 resident bed days during the intervention phase; no new pressure ulcers developed and the documented prevention behaviours included repositioning, skin inspection and checking support surfaces. Participants reported that the bundle enhanced the care they delivered and offered suggestions for future improvements. Our findings have highlighted a number of feasibility issues surrounding recruitment and retention, collecting data and implementation fidelity. A pressure ulcer prevention bundle specifically designed for nursing homes was acceptable. The feasibility work has highlighted the potential for the intervention and the areas that require development and refinement.

Abstract
This study aimed to investigate Korean nurses' level of knowledge, attitude, and performance of pressure ulcer prevention in long-term care facilities. A descriptive study was performed. Convenience sampling was used, and registered nurses were recruited from the attendees of a continuing education programme for nurses in long-term care facilities. A total of 282 participants (RN) completed the questionnaire. Data were collected from September to December 2015. Nurses participating in this study demonstrated a moderate level of knowledge of pressure ulcer prevention (60.1%) and exhibited positive attitudes towards pressure ulcer prevention (33.80 ± 2.48). Nurses regularly assessed the risk factors of pressure ulcers during the hospitalisation period for all patients in the hospital when performing pressure ulcer prevention care. However, the plan for preventive nursing care was not properly reviewed. It was also found that nurses did not consider changes in the patient's condition as important to why they had to change their nursing plans to prevent pressure ulcer. Therefore, this study suggested that appropriate guidelines, education programmes, and an environment that makes it possible to provide continuing education should be created for nurses to prevent pressure ulcers in Korea's long-term care facilities.

Release of sodium pyruvate from sacral prophylactic dressings: A computational model. Int Wound J 2019; 16:1000-1008.

Abstract
The use of sacral dressings for pressure ulcer prevention is growing rapidly. In addition to their passive biomechanical role in pressure and shear reduction, in the near future, prophylactic dressings may also provide active tissue protection by releasing preventive agents or drugs into skin and deeper tissues. We investigated delivery of sodium pyruvate (NaPy) from an active dressing to potentially protect the sacral skin and underlying tissues in addition. We used four finite element model variants describing different skin roughness levels to determine time profiles of NaPy diffusion from the dressing into the skin layers. The NaPy concentrations for the different modelled cases stabilised after 1 to 6.5 hours from the time of application of the dressings, at 1% to 3% of the NaPy concentration in the dressing reservoir, which is considered potent. We conclude that prophylactic sacral dressings have the potential to deliver NaPy into skin and subdermally, to potentially increase soft tissue tolerance to sustained bodyweight-caused cell and tissue deformations. The time durations to achieve the steady-state potent NaPy dermal concentrations are clinically feasible, for example, for preparation of patients for surgery or for use in intensive care units.

Phantom testing of the sensitivity and precision of a sub-epidermal moisture scanner. Int Wound J 2019; 16:979-988.

Abstract
The majority of pressure ulcers (PUs) including deep tissue injuries (DTIs) are preventable, and even reversible if detected in their early phase. One of the greatest barriers in PU prevention is that clinicians traditionally depended on subjective and qualitative techniques, particularly routine visual skin assessments that would only document existing, macroscopic PUs/DTIs, rather than preventing them or detecting them at their microscopic phase. At the early phase of cell damage, when a forming PU is still microscopic, there is a local increase in extracellular fluid contents within affected tissues, which is called sub-epidermal moisture (SEM). This new understanding has led to an emerging technology, a SEM Scanner (BBI LLC, Bruin Biometrics) that has been designed to effectively examine the health status of tissues, by measuring local changes in the biophysical SEM marker. In the present work, the SEM Scanner was tested under controlled laboratory conditions to experimentally determine its sensitivity and precision in identifying small (1 mL) water content changes in phantoms of the human heel and skull/face, which simulated common PU development scenarios. In both phantom configurations, the locally increased water contents resulted in consistent, statistically significant elevated SEM readings, which confirms that the SEM Scanner is able to detect fluid content changes that are as small as 1 mL. In agreement with a simplified theoretical (mathematical) SEM model, which was also developed here, changes in water contents had a consistent trend of effect on SEM delta values, which increased with each 1 mL increment in intra-tissue-substitute water contents.

Abstract
AIM To study the relationship between pressure ulcer risk evaluated by the Norton Scale and inadequate fulfilment of Need 2 (Eating/Drinking) from the 14-need classification designed by Virginia Henderson. BACKGROUND Assessing nutritional status and skin condition to implement preventive measures are important nursing interventions. Our hospital's standard procedure requires recording Norton Scale and Henderson Eating/Drinking Assessment results. METHODS This was a descriptive cross-sectional study, analysing case histories of 219 patients in medical/surgical wards for >24 hr with nursing care recorded in the GACELA Care computer application. Patient sociodemographic variables and evaluation concepts from the Norton Scale and Eating/Drinking were studied. RESULTS A statistically significant relationship (p < 0.05; 95% CI: 0.61, 2.83) was seen between inadequate Eating/Drinking need fulfilment and increased pressure ulcer risk. Pressure ulcer risk was generally low in the sample, with mainly no or minimum risk (77.3%); the oldest age group had the highest risk. Self-care autonomy was the most frequently assessed item in Eating/Drinking (42%). CONCLUSIONS A relationship was found between Norton Scale risk results and Eating/Drinking need assessment results. The greater the pressure ulcer risk, the more likely was inadequate need satisfaction (poor nutritional status). IMPLICATIONS To help identify pressure ulcer risk, nurses should assess patients' eating independence. Safeguarding nutritional status and preventing pressure ulcers are nursing skills associated with quality nursing care.

Reduction of Prolonged Excessive Pressure in Seated Persons With Paraplegia Using Wireless Lingual Tactile Feedback: A Randomized Controlled Trial. IEEE JOURNAL OF TRANSLATIONAL ENGINEERING IN HEALTH AND MEDICINE-JTEHM 2018; 6:2100611. [PMID: 29984117 PMCID: PMC6033051 DOI: 10.1109/jtehm.2018.2842746] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/20/2017] [Revised: 04/26/2018] [Accepted: 05/25/2018] [Indexed: 11/10/2022]
Abstract
Pressure ulcers (PU) are known to be a high-cost disease with a risk of severe morbidity. This paper evaluates a new clinical strategy based on an innovative medical device [Tongue Display Unit (TDU)] that implements perceptive supplementation in order to reduce prolonged excessive pressure, recognized as one of the main causes of PU. A randomized, controlled, and parallel-group trial was carried out with 12 subjects with spinal cord injuries (SCI). Subjects were assigned to the control (without TDU, [Formula: see text]) or intervention (with TDU, [Formula: see text]) group. Each subject took part in two sessions, during which the subject, seated on a pressure map sensor, watched a movie for one hour. The TDU was activated during the second session of the intervention group. Intention-to-treat analysis showed that the improvement in adequate weight shifting between the two sessions was higher in the intervention group (0.84 [0.24; 0.89]) than in the control group (0.01 [-0.01; 0.09]; [Formula: see text]) and that the ratio of prolonged excessive pressure between the two sessions was lower in the intervention group (0.74 [0.37; 1.92]) than in the control group (1.72 [1.32; 2.56]; [Formula: see text]). The pressure map sensor was evaluated as being convenient for use in daily life; however, this was not the case for the TDU. This paper shows that persons with SCI could benefit from a system based on perceptive supplementation that alerts and guides the user on how to adapt their posture in order to reduce prolonged excessive pressure, one of the main causes of PU.

Effectiveness of using a new polyurethane foam multi-layer dressing in the sacral area to prevent the onset of pressure ulcer in the elderly with hip fractures: A pragmatic randomised controlled trial. Int Wound J 2018; 15:383-390. [PMID: 29314659 PMCID: PMC7950011 DOI: 10.1111/iwj.12875] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Revised: 11/03/2017] [Accepted: 11/16/2017] [Indexed: 01/01/2023] Open
Abstract
Hip fractures in the elderly are a serious problem for the health service due to the high rate of complications. One of these complications is pressure ulcers that, according to the literature, occur in 8.8% to 55% of patients and mainly arise in the sacral area. The present randomised controlled trial tests whether applying a new innovative multi‐layer polyurethane foam dressing (ALLEVYN LIFE™), reduces the onset of pressure ulcers in the sacral area. From March to December 2016, 359 fragility hip fracture patients were randomly divided into 2 groups: 182 in the control group and 177 in the experimental group. Pressure ulcers occurred overall in 36 patients (10%): 8 patients (4.5%) in the experimental group compared to 28 (15.4%) in the control group: P = 0.001, relative risk 0.29 (95% CI 0.14‐0.61) with NNT of 9 (95% CI 6‐21). In the experimental group the onset of pressure ulcers occurred on average on the 6th day compared to the 4th day in the control group (HR 4.4). Using polyurethane foam is effective at reducing the rate of pressure ulcers in the sacrum in elderly patients with hip fracture. The adhesiveness of this device also enables costs to be kept down.

Abstract
Pressure ulcers are painful, and affect patients' health, mobility and well-being. They also cost the NHS between £1.4-2.1 billion a year. Although a large proportion of pressure ulcers are avoidable, many still occur and, because pressure ulcer incidence is an indicator of care quality, it can put carers under scrutiny. The National Institute for Health and Care Excellence states that adequate risk assessment of pressure ulcer development, including the role of malnutrition, improves care. Adequate nutrition is vital for the prevention of pressure ulcers and malnutrition can hinder healing when pressure ulcers have developed. The risk of malnutrition should be assessed with a recognised tool, such as the Malnutrition Universal Screening Tool, and appropriate treatment plans should be drawn up for patients identified as being at risk of malnutrition to improve their nutritional state. For example, the dietary intake of people with poor appetite can be supplemented with nutritious snacks between meals. The aims of this article are to help readers understand risk factors for malnutrition and how dietary intake can be manipulated to improve patients' nutritional state. It also aims to highlight how improving nutritional intake helps to prevent pressure ulcers. On completing the article, readers will be able to consider and review their own practice.

Abstract
BACKGROUND In 2013, an observational survey was conducted among 242 in-patients in a community hospital with a pressure ulcer (PU) prevalence of 34.3%. An evidence-based pressure ulcer prevention program (PUPP) was then implemented including a staff awareness campaign entitled "Healthy Skin Wins" with an online tutorial about PU prevention. AIMS To determine the effectiveness of the PUPP in reducing the prevalence of PUs, to determine the effectiveness of the online tutorial in increasing hospital staff's knowledge level about PU prevention, and to explore frontline staff's perspectives of the PUPP. METHODS This was a mixed methods study. A repeat observational survey discerned if the PUPP reduced PU prevalence. A pre-test post-test design was used to determine whether hospital staff's knowledge of PU prevention was enhanced by the online tutorial. Qualitative interviews were conducted with nurses, allied health professionals, and health care aides to explore staff's perspectives of the PUPP. RESULTS A comparison of initial and repeat observational surveys (n = 239) identified a statistically significant reduction in the prevalence of PU to 7.53% (p < .001). The online tutorial enhanced staff knowledge level with a statistically significantly higher mean post-test score (n = 80). Thirty-five frontline staff shared their perspectives of the PUPP with "it's definitely a combination of everything" and "there's a disconnect between what's needed and what's available" as the main themes. CONCLUSIONS Incorporating evidence-based PU prevention into clinical practice greatly reduced the prevalence of PUs among hospital in-patients. Due to the small sample size for the pre-test post-test component, the effectiveness of the online tutorial in improving the knowledge level of PU prevention among hospital staff requires further research. LINKING EVIDENCE TO ACTION Evidence-based PU prevention strategies are facilitated by using a multidisciplinary approach. Educational tools about PU prevention must target all members of the healthcare team including healthcare aides, patients and families.

Abstract
BACKGROUND Pressure ulcers place a significant burden on patients and hospitals. Our team developed and tested a pressure ulcer prevention care bundle (PUPCB) in a cluster randomized trial. As part of the process evaluation conducted alongside the trial, we explored patients' perceptions of the intervention. AIMS To identify patients' perceptions and experiences of a PUPCB in hospital. METHODS This qualitative descriptive study explored the perceptions of a subset of patients who participated in a trial testing the PUPCB across four intervention hospitals. A trained interviewer conducted semistructured interviews, which were digitally recorded, transcribed, and analyzed using thematic analysis. FINDINGS Nineteen patients were interviewed across the four hospitals. Three main themes emerged: (a) importance of personal contact in PUPCB delivery; (b) understanding pressure ulcer prevention (PUP) enhances participation; and (c) individual factors impact patients' engagement in PUP. DISCUSSION The extent to which patients adopted the intervention appeared to be influenced by the complexity of education materials, compatibility with patients' existing knowledge and beliefs, and perceived advantage of the intervention; ability for human interaction; and patient-related facilitators and barriers to participating in PUP care. LINKING EVIDENCE TO ACTION This study found patients accepted a PUPCB that encouraged participation in care, particularly as it involved personal and positive interactions with nurses and provision of information that was easy to understand and resonated with patients.

Abstract
AIMS The aim of this study was to develop the Patient Participation in Pressure injury Prevention (PPPIP) scale and undertake initial testing of some of its psychometric properties. BACKGROUND Clinical practice guidelines recommend patient involvement in pressure injury prevention. There is some evidence that patients are willing to participate in this activity, but there are currently no instruments to measure this participation. DESIGN This methodological study used data collected as part of a cluster randomized trial to develop and test the PPPIP scale. METHODS A sample of 688 of patients with complete PPPIP scale data was used. A stratified random subsample, (Subsample A) was created and the remainder became Subsample B. Item analysis, exploratory factor analysis and Cronbach's alpha reliability were undertaken in Subsample A. Confirmatory factor analysis and Cronbach's alpha reliability were undertaken in Subsample B. Data collection occurred between June 2014 - May 2015. RESULTS In Subsample A (n = 320), inter-item correlations, item total correlations met the acceptance criteria and an exploratory factor analysis identified a one factor solution. In Subsample B (n = 368), the confirmatory factor analysis supported this one factor. In both subsamples, the Cronbach's alpha was 0·86. CONCLUSION This study provides preliminary evidence of acceptable reliability and validity of the PPPIP scale in two subsamples of hospitalized patients who had limited mobility. It may be used in research and quality improvement activities. As a better conceptual understanding of patient participation emerges, the PPPIP scale may require refinement.

Abstract
Pressure ulcer prevention in the care home setting can be challenging and is often compromised by a lack of access to education and resources. There are measures that have been shown to consistently improve outcomes in pressure ulcer prevention including assessment of the patient and their individual risks, delivery of a consistent plan of care that meets patients' needs, and regular evaluation to identify shortfalls. In addition, there should be a robust approach to investigating events that lead to a person developing a pressure ulcer and that information should be used to improve future practice. Pressure ulcer prevention in care homes is achievable and nurses should all be aware of the necessary measures detailed in this article.

Abstract
Pressure ulcers (PUs) in individuals with spinal cord injury (SCI) present a persistent and costly problem. Continuing effort in developing new technologies that support self-managed care is an important prevention strategy. Specifically, the aims of this scoping review are to review the key concepts and factors related to self-managed prevention of PUs in individuals with SCI and appraise the technologies available to assist patients in self-management of PU prevention practices. There is broad consensus that sustaining long-term adherence to prevention regimens is a major concern. Recent literature highlights the interactions between behavioral and physiological risk factors. We identify four technology categories that support self-management: computer-based educational technologies demonstrated improved short-term gains in knowledge (2 studies), interface pressure mapping technologies demonstrated improved adherence to pressure-relief schedules up to 3 mo (5 studies), electrical stimulation confirmed improvements in tissue tolerance after 8 wk of training (3 studies), and telemedicine programs demonstrated improvements in independence and reduced hospital visits over 6 mo (2 studies). Overall, self-management technologies demonstrated low-to-moderate effectiveness in addressing a subset of risk factors. However, the effectiveness of technologies in preventing PUs is limited due to a lack of incidence reporting. In light of the key findings, we recommend developing integrated technologies that address multiple risk factors.

Abstract
Pressure ulcers are painful and cause discomfort, have a negative effect on quality of life, and are costly to treat. The incidence and severity of preventable pressure ulcers is an important indicator of quality of care; it is essential that healthcare providers monitor prevalence and incidence rates to ensure that care strategies implemented are effective. Frail older people are at increased risk of developing pressure ulcers. This article discusses the complexities of preventing pressure ulcers in frail older people and emphasises the importance of structured educational programmes that incorporate effective clinical leadership and multidisciplinary teamwork.

Abstract
OBJECTIVE In this study, we evaluated the effect of hip-joint rotation on the interface pressure over the sacrum and greater trochanter with a new protocol for positioning of bedridden elderly patients. METHOD The interface pressure values over the sacrum and greater trochanter in bedridden patients were evaluated. These were collected in the supine position, 90° lateral position, and 30° and 40° laterally inclined positions with external rotation or neutral positioning of the hip joint. Each interface pressure was assessed with a device measuring pressure distribution, after which, the peak pressure index (PPI) was calculated. RESULTS In the 17 patients examined, the PPI over the sacrum in the supine position was significantly greater than that in other positions. In the 30° and 40° laterally inclined positions, the PPIs over the greater trochanter were significantly lower in the neutral position of the hip joint compared with those in the external rotation position. CONCLUSION Our findings revealed the effects of hip-joint rotation on the interface pressure for the greater trochanter, possibly due to the increased distance between the greater trochanter and the sacrum caused by neutral position of the hip joint. The results demonstrate that it is to best place the hip joint in a neutral position when the legs are in contact with the bed in order to distribute the pressure over the greater trochanter in the 30° and 40° laterally inclined positions. These results can be applied to the clinical setting to improve patient positioning and decrease pressure ulcers. DECLARATION OF INTEREST The authors declare that they have no competing financial interests.

Abstract
A multidisciplinary process improvement program was initiated at the University of Miami Hospital (UMH) in 2009 to identify the prevalence of hospital-acquired pressure ulcers (HAPU) at the institution and to implement interventions to reduce the incidence of HAPU. This deliberate and thoughtful committee-driven process evaluated care, monitored results, and designed evidence-based strategic initiatives to manage and reduce the rate of HAPU. As a result all inpatient beds were replaced with support surfaces, updated care delivery protocols were created, and monitored, turning schedules were addressed, and a wound, ostomy, and continence (WOC) nurse and support staff were hired. These initial interventions resulted in a decrease in the prevalence of HAPU at UMH from 11.7% of stage II to IV ulcers in the second quarter, 2009 to 2.1% the third quarter. The rate remained at or near the 2009 UMH benchmark of 3.1% until the first quarter of 2012 when the rate rose to 4.1%. At that time new skin products were introduced into practice and continuing re-education was provided. The rate of HAPU dropped to 2.76% by the second quarter of 2012 and has remained steadily low at 1%-2% for nine consecutive quarters.

Abstract
This article outlines an innovative way of preventing pressure ulcers in the acute hospital setting. A programme using Rapid Spread Methodology was undertaken to reduce hospital-acquired pressure ulcers over a short period of time. Results demonstrated a reduction to zero in the prevalence of hospital-acquired pressure ulcers and an 80% reduction in their incidence, in a six-month period.

Abstract
As patients increasingly care for themselves at home, they require accessible information to enable informed self-care. This article describes the development of an educational electronic application (app) designed for use by patients at risk of pressure ulcers, and their carers. The app can be downloaded to Windows, Android or Apple smartphones or tablets. The app is based on the current pressure ulcer prevention and management guidelines from the National Pressure Ulcer Advisory Panel and the National Institute for Health and Care Excellence, and is designed to educate patients and carers about how to prevent a pressure ulcer, how to recognise a pressure ulcer, and what to do if they suspect they are developing a pressure ulcer. We hope the app will be used to help with educational conversations among patients, carers and healthcare professionals.

Abstract
PURPOSE The purpose of this study was to compare pressure ulcer prevention programs in 2 long-term care (LTC) facilities with diverse Information Technology Sophistication (ITS), one with high sophistication and one with low sophistication, and to identify implications for the WOC nurse. DESIGN Secondary analysis of narrative data obtained from a mixed-methods study. SUBJECTS AND SETTING The study setting was 2 LTC facilities in the Midwestern United States. The sample comprised 39 staff from 2 facilities, including 26 from a high-ITS facility and 13 from the low-ITS facility. Respondents included certified nurse assistants, certified medical technicians, restorative medical technicians, social workers, RNs, licensed practical nurses, information technology staff, administrators, and directors. METHODS This study is a secondary analysis of interviews regarding communication and education strategies in 2 LTC agencies. This analysis focused on focus group interviews, which included both direct and nondirect care providers. RESULTS Eight themes (codes) were identified in the analysis. Three themes are presented individually with exemplars of communication and education strategies. The analysis revealed specific differences between the high-ITS and low-ITS facilities in regard to education and communication involving pressure ulcer prevention. These differences have direct implications for WOC nurses consulting in the LTC setting. CONCLUSIONS Findings from this study suggest that effective strategies for staff education and communication regarding PU prevention differ based on the level of ITS within a given facility. Specific strategies for education and communication are suggested for agencies with high ITS and agencies with low ITS.

The effect of concentration of tackifying agent on adhesive and skin-protective properties of ceramide 2-containing hydrocolloid dressings. J Wound Care 2014; 24:41-8.

Abstract
OBJECTIVE In the treatment of pressure ulcers and leg ulcers it is necessary to achieve an effective balance between adhesive and skin-protective properties. We speculated that addition of a tackifying agent (TA) to ceramide 2-containing hydrocolloid dressings would increase their adhesiveness under dry conditions and reduce their adhesiveness under wet conditions because dry tack converts to wet tack after water absorption. METHOD We prepared ceramide 2-containing hydrocolloid dressings with varying amounts of TA. Basic characteristics of the test ceraminde dressings, such as initial tack force and peeling force, were evaluated using standard methods. Peeling force and stratum corneum (SC) removal on healthy human skin were also evaluated at 20 minutes, 7 hours, and 72 hours. In addition, the effect of 10 repeated applications on transepidermal water loss (TEWL) was investigated on the skin of hairless mice under dry and wet conditions. Statistical analyses were performed using one-way analysis of variance followed by Dunnett's multiple comparison test. A p-value of <0.05 was considered statistically significant. RESULTS On a stainless steel substrate, initial tack force and 180° peeling force increased as TA content increased. Twenty minutes after application on human skin, peeling force and SC removal increased with increasing TA content. When TA contents were over 10%, significant differences in peeling force and SC removal were obtained compared with ceramide 2-containing hydrocolloid dressings without TA (p<0.05). However, a TA content-dependent increase in peeling force was not evident 7 hours and 72 hours after application. Under dry conditions, TEWL increased with repeated application and peeling. Conversely, no significant increases in TEWL were evident under wet conditions after 10 repeated applications and peelings. CONCLUSION Our data demonstrate that the initial attachment of ceramide 2-containing hydrocolloid dressings to the skin increases with addition of TA. Skin damage can be avoided by conversion of the adhesive system to wet tack with water absorption. DECLARATION OF INTEREST Masushi Kohta and Tetsuji IwasakI are employees of ALCARE Co., Ltd., Japan.

[Quality measurement using administrative data in mandatory quality assurance]. ZEITSCHRIFT FUR EVIDENZ FORTBILDUNG UND QUALITAET IM GESUNDHEITSWESEN 2014; 108:465-9. [PMID: 25523844 DOI: 10.1016/j.zefq.2014.09.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2014] [Revised: 09/22/2014] [Accepted: 09/22/2014] [Indexed: 11/19/2022]
Abstract
For several years, the use of administrative data in mandatory quality measurement has been requested by several stakeholders in Germany. Main advantages of using administrative data include the reduction of documentary expenditures and the possibility to perform longitudinal quality analyses across different healthcare units. After a short introduction, a brief overview of the current use of administrative data for mandatory quality assurance as well as current developments is given, which will then be further exemplified by decubital ulcer prophylaxis. By using administrative data coding expenditures in this clinical area could be reduced by nine million data fields. At the same time the population analysed was expanded resulting in a more than tenfold increase in potentially quality-relevant events. Finally, perspectives, further developments, possibilities as well as limits of quality measurement with administrative data are discussed.

Abstract
Pressure ulcers represent a considerable cost, both in terms of healthcare spending and quality of life. They are increasingly viewed in terms of patient harm. For clinicians involved in pressure ulcer prevention, ethical issues surrounding accountability may arise from both policy and practice perspectives. It may be useful for clinicians to refer to ethical theories and principles to create frameworks when addressing ethical dilemmas. However, such theories and principles have been criticised for their simplicity and over-generalisation. Alternative theories, for example, virtue ethics and experiential learning, can provide more comprehensive guidance and promote a pluralistic approach to tackling ethical dilemmas.

Evaluation of Cueing Innovation for Pressure Ulcer Prevention Using Staff Focus Groups. Healthcare (Basel) 2014; 2:299-314. [PMID: 27429278 PMCID: PMC4934592 DOI: 10.3390/healthcare2030299] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2014] [Revised: 07/03/2014] [Accepted: 07/10/2014] [Indexed: 11/16/2022] Open
Abstract
UNLABELLED The purpose of the manuscript is to describe long-term care (LTC) staff perceptions of a music cueing intervention designed to improve staff integration of pressure ulcer (PrU) prevention guidelines regarding consistent and regular movement of LTC residents a minimum of every two hours. The Diffusion of Innovation (DOI) model guided staff interviews about their perceptions of the intervention's characteristics, outcomes, and sustainability. METHODS This was a qualitative, observational study of staff perceptions of the PrU prevention intervention conducted in Midwestern U.S. LTC facilities (N = 45 staff members). One focus group was held in each of eight intervention facilities using a semi-structured interview protocol. Transcripts were analyzed using thematic content analysis, and summaries for each category were compared across groups. RESULTS The a priori codes (observability, trialability, compatibility, relative advantage and complexity) described the innovation characteristics, and the sixth code, sustainability, was identified in the data. Within each code, two themes emerged as a positive or negative response regarding characteristics of the innovation. Moreover, within the sustainability code, a third theme emerged that was labeled "brainstormed ideas", focusing on strategies for improving the innovation. IMPLICATIONS Cueing LTC staff using music offers a sustainable potential to improve PrU prevention practices, to increase resident movement, which can subsequently lead to a reduction in PrUs.

Implementing trials of complex interventions in community settings: the USC-Rancho Los Amigos pressure ulcer prevention study (PUPS). Clin Trials 2014; 11:218-29.

Abstract
BACKGROUND Randomized trials of complex, non-pharmacologic interventions implemented in home and community settings, such as the University of Southern California (USC)-Rancho Los Amigos National Rehabilitation Center (RLANRC) Pressure Ulcer Prevention Study (PUPS), present unique challenges with respect to (1) participant recruitment and retention, (2) intervention delivery and fidelity, (3) randomization and assessment, and (4) potential inadvertent treatment effects. PURPOSE We describe the methods employed to address the challenges confronted in implementing PUPS. In this randomized controlled trial, we are assessing the efficacy of a complex, preventive intervention in reducing the incidence of, and costs associated with, the development of medically serious pressure ulcers in people with spinal cord injury. METHODS Individuals with spinal cord injury recruited from RLANRC were assigned to either a 12-month preventive intervention group or a standard care control group. The primary outcome is the incidence of serious pressure ulcers with secondary endpoints including ulcer-related surgeries, medical treatment costs, and quality of life. These outcomes are assessed at 12 and 24 months after randomization. Additionally, we are studying the mediating mechanisms that account for intervention outcomes. RESULTS PUPS has been successfully implemented, including recruitment of the target sample size of 170 participants, assurance of the integrity of intervention protocol delivery with an average 90% treatment adherence rate, and enactment of the assessment plan. However, implementation has been replete with challenges. To meet recruitment goals, we instituted a five-pronged approach customized for an underserved, ethnically diverse population. In intervention delivery, we increased staff time to overcome economic and cultural barriers to retention and adherence. To ensure treatment fidelity and replicability, we monitored intervention protocol delivery in accordance with a rigorous plan. Finally, we have overcome unanticipated assessment and design concerns related to (1) determining pressure ulcer incidence/severity, (2) randomization imbalance, and (3) inadvertent potential control group contamination. LIMITATIONS We have addressed the most daunting challenges encountered in the recruitment, assessment, and intervention phases of PUPS. Some challenges and solutions may not apply to trials conducted in other settings. CONCLUSIONS Overcoming challenges has required a multifaceted approach incorporating individualization, flexibility, and persistence, as well as the ability to implement needed mid-course corrections.

Abstract
Pressure injury guidelines recommend regular repositioning yet patients' mobility and repositioning patterns are unknown. An observational study using activity monitors was undertaken to describe the 24 h activity patterns of 84 hospitalized patients at risk of developing a pressure injury. The vast majority of participants' time was spent in the sedentary activity range (94% ± 3%) followed by the light range (5% ± 4 %). Patients changed their posture a median of 94 (interquartile range 48) time in the 24-h period (range 11-154), or ≈ 3.8 times per hour. Although a main focus for pressure injury prevention has been on repositioning, this study shows that patients with restricted mobility are actually moving quite often. Therefore, it might be appropriate to focus more attention on other pressure injury prevention strategies such as adequate nutrition, appropriate support surfaces and good skin care.
