A realist evaluation of devices used for the prevention of heel pressure ulcers: An ethnographic study of clinical practice.

BACKGROUND: It is known that heel offloading devices are widely used in clinical practice for the prevention of heel pressure ulcers, even though there is a lack of robust, good quality evidence to inform their use. OBJECTIVE: To explore how and why heel offloading devices are used (or not used) and reasoning behind their use in population at high risk of developing heel pressure ulcers. METHODS: An ethnographic study was conducted as part of a realist evaluation in three orthopaedic wards in a large English hospital. Twelve observations took place, with 49 h and 35 min of patient care observed. A total of 32 patients were observed and 19 members of the nursing team were interviewed and in-depth interviews with the three ward managers were conducted. RESULTS: Although the focus of the study was on offloading devices, constant low pressure heel specific devices were also observed in use for pressure ulcer prevention, whilst offloading devices were perceived to be for higher risk patients or those already with a heel pressure ulcer. Nursing staff viewed leadership from the ward manager and the influence of the Tissue Viability Nurse Specialists as key mechanisms for the proactive use of devices. CONCLUSIONS: This study informs trial design as it has identified that a controlled clinical trial of both types of heel specific devices is required to inform evidence-based practice. Involving the ward managers and Tissue Viability Nurse Specialists during set up phase for clinical equipoise could improve recruitment.

Role of nutritional support in nursing practice for improving surgical site wound healing in patients post-surgery with risk of pressure ulcers.

To explore the role of nutritional support in nursing practice on postoperative surgical site wound healing in patients undergoing surgery at risk for pressure ulcers. This study adopted a retrospective experimental design and included a total of 60 patients at risk of pressure ulcers, divided into a nutritional support group and a control group, with 30 people in each group. The nutritional support group implemented specific nutritional support measures after surgery, while the control group received standard postoperative care. Outcome measures included redness and swelling scores, edema scores, anxiety assessments, pain scores, bleeding volume, recovery time and incidence of pressure ulcers. The result indicates that patients who received nutritional support exhibited lower postoperative wound redness and swelling scores compared to the control group (3.11 ± 0.45 vs. 4.85 ± 0.74, p < 0.05). Additionally, the nutritional support group showed significantly lower edema scores (2.75 ± 0.37 vs. 3.53 ± 0.62, p < 0.05). Anxiety levels, as measured by the anxiety assessment scale (SAS), were also lower in the nutritional support group (6.52 ± 1.19 vs. 7.60 ± 1.62, p < 0.05). Moreover, the average healing time was shorter for the nutritional support group (7.27 ± 1.36 days) compared to the control group (9.71 ± 1.84 days, p < 0.05). Postoperative pain scores were lower in the nutritional support group (4.13 ± 0.72 vs. 5.43 ± 0.62, p < 0.05), and patient satisfaction scores were higher (9.42 ± 0.76 vs. 7.25 ± 0.81, p < 0.05). Nutritional support has a positive effect on postoperative wound healing at surgical sites in patients at risk of pressure ulcers in nursing practice. It can significantly reduce redness, swelling, edema, anxiety, and pain scores, reduce bleeding, shorten recovery time, and reduce pressure ulcers. incidence rate.

Evaluating the efficacy of standardized pressure ulcer management protocols in the prevention of pressure injuries among patients undergoing neurosurgical procedures.

Pressure injuries are a significant concern for patients undergoing neurosurgical procedures due to prolonged immobility and the complexity of care. This study evaluates the efficacy of standardized pressure ulcer management protocols in preventing pressure injuries and enhancing patient care in a neurosurgical context. A comprehensive retrospective analysis was conducted at a single institution from December 2020 to December 2023, comparing 50 patients who received standardized pressure ulcer management (intervention group) with 50 patients who received conventional care (control group). The study assessed the incidence of pressure ulcers, patient comfort levels using the Kolcaba Comfort Scale and sleep quality using the Richards-Campbell Sleep Questionnaire (RCSQ). Statistical analysis was performed using SPSS software, version 27.0, applying t-tests and chi-square tests as appropriate. The intervention group exhibited a significantly lower incidence of pressure ulcers at all measured time points post-surgery compared to the control group. Patient comfort levels in the intervention group were consistently higher across psychological, environmental, physiological and socio-cultural domains. Sleep quality metrics, including sleep depth, latency to sleep onset and overall sleep quality, were significantly improved in the intervention group. The implementation of standardized pressure ulcer management protocols in neurosurgical care significantly reduces the incidence of pressure injuries, enhances patient comfort and improves sleep quality. These findings highlight the importance of adopting structured care protocols to improve postoperative outcomes and patient well-being in neurosurgical settings.

Nursing care bundles in the prevention of medical device related pressure ulcers: An integrative review.

The aim of this integrative review was to explore the effect of care bundles in the prevention of Medical Device Related Pressure Ulcers (MDRPU). An MDRPU is a wound that occurs on the skin or mucosal membranes because of pressure or pressure in combination with shear. Like other types of pressure ulcers, they will have negative consequences for patients and healthcare organisations alike. Many MDRPU's are preventable. A literature search was undertaken from computerised databases using key search terms, Pressure Ulcer* Pressure Injur* and Medical Device*. Databases included CINAHL; Medline and SocIndex. A total of seven studies were found that met the criteria for inclusion in this review. When compared to the widely recognised and trusted international guidelines there was variation found between the individual interventions selected within each study for inclusion within the bundle. Skin assessment and device repositioning were the most frequently included interventions in the bundles, followed by use of prophylactic dressings, appropriate device selection and fitting. The least common intervention was monitoring the tension of the device and/or its securements. All studies reported a reduction in the number of MDRPU's when care bundles were used in clinical practice. However, there is variation in bundle designs and study methodologies employed. This review has demonstrated the potential benefit of care bundles in reducing MDRPU. However, due to heterogeneity in the study methods employed and the interventions within the care bundles, further, more robust research is required to establish which interventions show the most clinical and patient benefit.

The effect of pressure injury prevention care bundles on pressure injuries in hospital patients: A complex intervention systematic review and meta-analysis.

BACKGROUND: Numerous interventions for pressure injury prevention have been developed, including care bundles. OBJECTIVE: To systematically review the effectiveness of pressure injury prevention care bundles on pressure injury prevalence, incidence, and hospital-acquired pressure injury rate in hospitalised patients. DATA SOURCES: The Medical Literature Analysis and Retrieval System Online (via PubMed), the Cumulative Index to Nursing and Allied Health Literature, EMBASE, Scopus, the Cochrane Library and two registries were searched (from 2009 to September 2023). STUDY ELIGIBILITY CRITERIA: Randomised controlled trials and non-randomised studies with a comparison group published in English after 2008 were included. Studies reporting on the frequency of pressure injuries where the number of patients was not the numerator or denominator, or where the denominator was not reported, and single subgroups of hospitalised patients were excluded. Educational programmes targeting healthcare professionals and bundles targeting specific types of pressure injuries were excluded. PARTICIPANTS AND INTERVENTIONS: Bundles with ≥3 components directed towards patients and implemented in ≥2 hospital services were included. STUDY APPRAISAL AND SYNTHESIS METHODS: Screening, data extraction and risk of bias assessments were undertaken independently by two researchers. Random effects meta-analyses were conducted. The certainty of the body of evidence was assessed using Grading of Recommendations, Assessment, Development and Evaluation. RESULTS: Nine studies (seven non-randomised with historical controls; two randomised) conducted in eight countries were included. There were four to eight bundle components; most were core, and only a few were discretionary. Various strategies were used prior to (six studies), during (five studies) and after (two studies) implementation to embed the bundles. The pooled risk ratio for pressure injury prevalence (five non-randomised studies) was 0.55 (95 % confidence intervals 0.29-1.03), and for hospital-acquired pressure injury rate (five non-randomised studies) it was 0.31 (95 % confidence intervals 0.12-0.83). All non-randomised studies were at high risk of bias, with very low certainty of evidence. In the two randomised studies, the care bundles had non-significant effects on hospital-acquired pressure injury incidence density, but data could not be pooled. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: Whilst some studies showed decreases in pressure injuries, this evidence was very low certainty. The potential benefits of adding emerging evidence-based components to bundles should be considered. Future effectiveness studies should include contemporaneous controls and the development of a comprehensive, theory and evidence-informed implementation plan. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42023423058. TWEETABLE ABSTRACT: Pressure injury prevention care bundles decrease hospital-acquired pressure injuries, but the certainty of this evidence is very low.

Difficulties and obstacles experienced by intensive care unit nurses during the prevention and care of pressure injuries: A qualitative study.

AIM: This study aimed to examine the difficulties and obstacles experienced by nurses working in intensive care units during the prevention and care of pressure injuries (ulcers). MATERIALS AND METHODS: A descriptive phenomenological study was designed, involving 13 nurses working in the intensive care unit of a hospital in Turkey. The data were collected through face-to-face interviews. The data were analyzed using thematic analysis. The findings were reported according to the Consolidated Criteria for Reporting Qualitative Studies criteria. RESULTS: Through the data analysis, an overall theme "Prevention and Care of Pressure Injuries" and three main themes, namely "Obstacles Encountered", "Impacts on The Nurses", and "Needs and Recommendations" were identified. CONCLUSION: This study identified institution-related issues (lack of resources, managers' attitudes, etc.), as well as lack of knowledge and training prevent the effective management of pressure injuries in intensive care units. The development of pressure injuries emotionally and professionally affects nurses. The primary needs of nurses were found to be equipment and material support, personnel training, positive attitudes of institution managers, and the establishment of a wound care unit within the hospital. The following recommendations were made based on the obtained findings: practical training should be given to all intensive care unit teams based on the latest information, modern, practical, diverse, and sufficient amount of equipment for pressure injuries should be provided, personnel shortage should be eliminated, institution managers should exhibit solution-oriented attitudes toward nurses rather than accusatory approaches, and a wound care unit should be established within the hospital. This study was limited to the nurses working in the ICU of a state hospital in Turkey. Since the study was carried out in a single hospital and due to the personal characteristics of the participants, the findings cannot be generalized to all ICU nurses and healthcare institutions.

A Tracheostomy Support Device to Reduce Tracheostomy-Related Pressure Injury.

BACKGROUND: Tracheostomies provide many advantages for the care of patients who are critically ill but may also result in complications, including tracheostomy-related pressure injuries. Research efforts into the prevention of these pressure injuries has resulted in specialized clinical care teams and pathways. These solutions are expensive and labor intensive, and fail to target the root cause of these injuries; namely, pressure at the device-skin interface. Here we measure that pressure directly and introduce a novel medical device, the tracheostomy support system, to reduce it. METHODS: This was a cross-sectional study of 21 subjects in the ICU, each with a tracheostomy tube connected to a ventilator. A force-sensing resistor was used to measure baseline pressures at the device-skin interface along the inferior flange. This pressure was then measured again with the use of the tracheostomy support system in the inactive and active states. Resultant pressures and demographics were compared. RESULTS: Fifteen male and 6 female subjects, with an average age of 47 ± 14 (mean ± SD) years, were included in this study. Average pressures at the tracheostomy-skin interface at baseline in these 21 ICU subjects were 273 ± 115 (mean ± SD) mm Hg. Average pressures were reduced by 59% (median 62%, maximum 98%) with the active tracheostomy support system to 115 ± 83 mm Hg (P < .001). All the subjects tolerated the tracheostomy support system without issue. CONCLUSIONS: Despite best clinical practice, pressure at the tracheostomy-skin interface can remain quite high. Here we provide measures of this pressure directly and show that a tracheostomy support system can be highly effective at minimizing that pressure. There is room for improvement in tracheostomy care, and such improvement does not have to come at a great expense.

Association between hypertension and pressure ulcer: A systematic review and meta-analysis.

This review aims to systematically evaluate the association between hypertension and pressure ulcer (PU). PubMed, Embase, Web of Science, and Cochrane Library were searched for studies from their inception until September 12, 2023. Literature search, data extraction, and quality assessment were conducted independently by two researchers. The random-effects model was used to calculate the combined odds ratio (OR) and corresponding 95% confidence interval (CI) of hypertension in patients with PU; subgroup analyses were performed to explore the source of between-study heterogeneity; sensitivity analysis was used to test the robust of the combined result; and funnel plot and Egger's test were used to assess the publication bias. Finally, a total of 19 studies with 564 716 subjects were included; the overall pooled result showed no significant association between hypertension and risk of developing PU (OR = 1.15, 95% CI = 0.90-1.47, p = 0.27); and the sensitivity analysis and publication bias analysis showed robust of the combined result. Subgroup analysis indicated a significant association between hypertension and PU when the primary disease was COVID-19 (OR = 1.73, 95% CI = 1.35-2.22, p < 0.0001). No association between hypertension and PU was seen in subgroup analysis on the patient source and study design. In sum, there is no significantly statistical association between hypertension and the occurrence of PU in most cases, while the risk of PU significantly elevates among COVID-19 patients combined with hypertension regardless of patient source and study design.

Decreased proteasome function increases oxidative stress in the early stage of pressure ulcer development.

The aging process in the elderly results in heightened skin fragility associated with various disorders, including pressure ulcers (PUs). Despite the high incidence of PUs in the elderly population, there is a limited body of research specifically examining the impact of aging on the development of pressure ulcers. Therefore, investigating age-related physiological abnormalities is essential to elucidate the pathogenesis of PUs. Ischemia-reperfusion (I/R) injury and the subsequent oxidative stress caused by reactive oxygen species (ROS) play essential roles in the early stage of PUs. In this study, we used a mouse model of proteasomal dysfunction with an age-related phenotype to examine the role of proteasome activity in cutaneous I/R injury in vivo. Decreased proteasome function did not affect the expression of inflammatory cytokines and adhesion molecules in the I/R area in transgenic mice; however, proteasome inhibition increased oxidative stress that was not attenuated by activation of the oxidative stress response mediated by NF-E2-related factor 2 (Nrf2). In dermal fibroblasts (FCs) subjected to hypoxia-reoxygenation (H/R), proteasome inhibition induced oxidative stress and ROS production, and Nrf2 activation did not adequately upregulate antioxidant enzyme expression, possibly leading to antioxidant/oxidant imbalance. The free radical scavenger edaravone had protective effects against I/R injury in vivo and decreased oxidative stress in FCs treated with a proteasome inhibitor and subjected to H/R in vitro. The results suggest that the age-related decline in proteasome activity promotes cutaneous I/R injury-induced oxidative stress, and free radical scavengers may exert protective effects by preventing oxidative stress in the early stage of PUs.

Heel skin microclimate control: Secondary analysis of a self-controlled randomized clinical trial.

OBJECTIVE: this study was undertaken to evaluate the efficacy of multilayer polyurethane foam with silicone (MPF) compared to transparent polyurethane film (TPF) dressings in the control of heel skin microclimate (temperature and moisture) of hospitalized patients undergoing elective surgeries. METHOD: the study took of a secondary analysis of a randomized self-controlled trial, involving patients undergoing elective surgical procedure of cardiac and gastrointestinal specialties in a university hospital in southern Brazil, from March 2019 to February 2020. Patients served as their own control, with their heels randomly allocated to either TPF (control) or MPF (intervention). Skin temperature was measured using a digital infrared thermometer; and moisture determined through capacitance, at the beginning and end of surgery. The study was registered in the Brazilian Registry of Clinical Trials: RBR-5GKNG5. RESULTS: significant difference in the microclimate variables were observed when the groups (intervention and control) and the timepoint of measurement (beginning and end of surgery) were compared. When assessing temperature, an increase (+3.3 °C) was observed with TPF and a decrease (-7.4 °C) was recorded with MPF. Regarding skin moisture, an increase in moisture (+14.6 AU) was recorded with TPF and a slight decrease (-0.3 AU) with MPF. CONCLUSIONS: The findings of this study suggest that MPF is more effective than TPF in controlling skin microclimate (temperature and moisture) in heels skin of hospitalized patients undergoing elective surgeries. However, this control should be better investigated in other studies.

Complementing Braden scale for pressure ulcer risk with clinical and demographic-related factors in a large cohort of hospitalized Italian patients.

AIMS: To determine the prevalence, risk, and determinants of pressure ulcer risk in a large cohort of hospitalized patients. DESIGN: A prospective cross-sectional study with data collection in January 2023. METHODS: Registered nurses collected data from 798 patients admitted to 27 health care units of an Italian hospital. The pressure ulcer risk was assessed using the Braden scale. The presence of comorbidities was collected from clinical reports. Obesity was assessed according to international indicators (Body Mass Index). The receiver operating characteristic (ROC) curve was used to estimate the sensitivity and specificity of different Braden scores for identifying participants with pressure ulcers. RESULTS: The prevalence of pressure ulcers was 9.5%, and 57.4% of the sample were at risk of developing pressure ulcers. The area under the ROC curve was 0.88. The best sensitivity and specificity were found for a Braden cutoff score of 15.5 (sensibility = 0.76; specificity = 0.85). The determinants of lower Braden scores were older age (p < 0.001), comorbidities (p < 0.001), wounds of other nature (p = 0.001), urinary incontinence (p < 0.001), fecal incontinence (p < 0.001), and urinary catheterization (p < 0.001). CONCLUSION: Several demographic factors and specific clinical indicators have been identified as determinants of the risk of developing pressure ulcers, which are easily ascertainable by healthcare providers; thus, they may routinely complement the Braden Scale in the assessment of pressure ulcer risk in order to reinforce and accelerate clinical judgment.

Amputation-free Home Management of Infected Lower Extremity Pressure Ulcer through Shared Decision-making: Enhancing the Quality of Life and Highlighting Societal Significance in Home Care.

Home healthcare is important for allowing patients to live their lives. However, home-care bedridden patients often experience pressure ulcers in the lower extremities, which can lead to life-threatening infections requiring decisions on the need for amputation. We herein report a patient with an infected lower-limb pressure ulcer with a history of spinal injury. The patient, his family, and the home-care physician repeatedly shared decision-making to deliver home-based treatment instead of amputation. Administration of wound dressing, AQUACEL® Ag, led to complete epithelialization. Such shared decision-making and dressing were feasible in a home-care setting and broadened its scope.

Pressure ulcers in German hospitals: Analysis of reimbursement and length of stay.

Objective: Hospital-acquired pressure ulcers are an important indicator of the quality of care. Most pressure ulcers are avoidable with a robust protocol for prevention, but prevention activities often have a low priority for senior management because the true costs to the hospital are not visible. Our aim was to raise awareness of the value of pressure ulcer prevention by estimating the excess length of inpatient stay associated with hospital-acquired pressure ulcers, and by assessing whether additional costs are covered by increased reimbursement. Methods: National activity data for hospitals in Germany are available through the InEK Data Browser. Data were extracted covering discharges from German hospitals between January 1 and December 31, 2021. Cases were selected according to the presence of a pressure ulcer diagnosis using ICD-10-GM codes L89.0-L89.3. Information was extracted for the ten most common German Diagnosis-Related Group (G-DRG) codes in patients with a secondary pressure ulcer diagnosis on mean length of stay and average reimbursement. Ulcer-associated excess length of stay was estimated by comparing cases within the same G-DRG with and without a pressure ulcer diagnosis. Results: Mean length of stay was higher in patients with a pressure ulcer than in patients with no ulcer by between 1.9 (all ages) and 2.4 days (patients aged ≥65) per case. In patients aged ≥65 years, 22.1% of cases with a pressure ulcer had a length of stay above the norm for the DRG. In the German system length of stay above the norm is not normally reimbursed. Excess length of stay between 1.9 and 2.4 days leads to a potential cost to a hospital of between 1,633€ and 2,074€ per case. Conclusion: Hospital-acquired pressure ulcers represent an important source of cost for a hospital which highlights the potential value of effective prevention.

YouTube as a source of information for pressure injury: Quality assessment and content analysis.

We aimed to assess the quality and reliability of pressure injury-related videos uploaded on YouTube, analyse the sources and contents, and examine the correlation between video parameters. We searched YouTube using two keywords, "pressure ulcer" and "pressure sore", on August 20, 2022. We sorted the videos according to their number of views and included the top 100 videos for each keyword. The quality of videos was assessed using the Global Quality Scale (GQS), while their reliability was evaluated by the modified DISCERN (mDISCERN) tool. In addition, we evaluated the videos in which content was included, analysed the correlations and differences between GQS, mDISCERN, and video parameters. We initially found a total of 100 videos for each keyword and finally included and analysed 77 videos. The mean scores for the mDISCERN and GQS were 2.35 ± 0.98 and 3.09 ± 0.99, respectively. Both GQS and mDISCERN showed statistically significant correlations with each other (rho = 0.54, p < 0.0001*) and with the length of the videos, respectively (rho = 0.36, p = 0.001*), (rho = 0.29, p = 0.01*). Of the videos created by physicians, 8 (57.1%) included content related to treatment, while of the videos created by nonphysician health personnel, 22 (57.9%) included content related to prevention. Analysing whether there were differences in video parameters based on the sources, we observed significant differences between sources in GQS (p < 0.0001*), mDISCERN (p < 0.0001*), and video length (p = 0.001*). In the post-hoc analysis, videos uploaded by physicians or nonphysician health personnel showed higher quality and reliability than videos uploaded by other sources. Therefore, the results of this study could be useful for healthcare providers, as well as patients and caregivers, to search for high-quality and reliable YouTube videos related to pressure injury.

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.

Effectiveness of glutamine and arginine in wound healing of pressure ulcers: A systematic review protocol.

INTRODUCTION: Various nutrients play a physiological role in the healing process of pressure ulcers (PUs). Nutritional interventions include the administration of enteral nutritional supplements and formulas containing arginine, glutamine, and micronutrients. The aim of this systematic review is to evaluate the effectiveness of enteral nutritional supplements and formulas containing arginine and glutamine on wound-related outcomes. These include (1) time to healing, (2) changes in wound size, (3) local wound infection, (4) PU recurrence, and (5) PU-related pain. MATERIALS AND METHODS: This protocol was developed according to the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). A search will be conducted in the Cochrane Library, EMBASE, PubMed (MEDLINE), CINAHL (EBSCOhost interface) and Web of Science. In addition, a manual search will be conducted to identify relevant records. Except for systematic reviews, no restrictions will be placed on the study design, the population studied or the setting. Studies that do not address PUs, in vitro studies and studies that do not report wound-related outcomes will be excluded. Study selection, risk of bias assessment and data extraction will be performed independently by three researchers. Depending on the extent of heterogeneity of interventions, follow-up time and populations, results will be summarised either by meta-analysis or narrative synthesis. CONCLUSIONS: This is the first systematic review to identify, evaluate and summarise the current evidence for enteral arginine and glutamine supplementation on wound-related outcomes in PUs. The review will provide a solid basis for deriving valid and clinically relevant conclusions in this area.

Pressure injury risk assessment and prescription of preventative interventions using a structured tool versus clinical judgement: An interrater agreement study.

AIM: To assess agreement of pressure injury risk level and differences in preventative intervention prescription between nurses using a structured risk assessment tool compared with clinical judgement. DESIGN: Interrater agreement study. METHODS: Data were collected from November 2019 to December 2022. Paired nurse-assessors were allocated randomly to independently assess pressure injury risk using a structured tool (incorporating the Waterlow Score), or clinical judgement; then prescribe preventative interventions. Assessments were conducted on 150 acute patient participants in a general tertiary hospital. Agreement of risk level was analysed using absolute agreement proportions, weighted kappa and prevalence-adjusted and bias-adjusted kappa. RESULTS: Ninety-four nurse assessors participated. Absolute agreement of not-at-risk versus at-risk-any-level was substantial, but absolute agreement of risk-level was only fair. Clinical judgement assessors tended to underestimate risk. Where risk level was agreed, prescribed intervention frequencies were similar, although structured tool assessors prescribed more interventions mandated by standard care, while clinical judgement assessors prescribed more additional/optional interventions. Structured tool assessors prescribed more interventions targeted at lower-risk patients, whereas assessors using clinical judgement prescribed more interventions targeted at higher-risk patients. CONCLUSION: There were clear differences in pressure injury risk-level assessment between nurses using the two methods, with important differences in intervention prescription frequencies found. Further research is required into the use of both structured tools and clinical judgement to assess pressure injury risk, with emphasis on the impact of risk assessments on subsequent preventative intervention implementation. IMPACT: The results of this study are important for clinical practice as they demonstrate the influence of using a structured pressure injury risk assessment tool compared to clinical judgement. Whilst further research is required into the use of both structured tools and clinical judgement to assess pressure injury risk and prescribe interventions, our findings do not support a change in practice that would exclude the use of a structured pressure injury risk assessment tool. REPORTING METHOD: This study adhered to the GRRAS reporting guideline. PATIENT/PUBLIC CONTRIBUTION: No patient or public involvement in this study. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Educators and researchers can use the findings to guide teaching about pressure injury risk assessment and preventative intervention and to direct future studies. For clinical nurses and patients, a change in clinical practice that would exclude the use of a structured risk assessment tool is not recommended and further work is needed to validate the role of clinical judgement to assess risk and its impact on preventative intervention.

Determinants of pressure injury development in patients with COVID-19.

OBJECTIVE: Pressure injuries (PIs) often develop in critically ill patients due to immobility, and underlying comorbidities that decrease tissue perfusion and wound healing capacity. This study sought to provide epidemiological data on determinants and current managements practices of PI in patients with COVID-19. METHOD: A US national insurance-based database consisting of patients with coronavirus or COVID-19 diagnoses was used for data collection. Patients were filtered by International Classification of Diseases (ICD) codes corresponding to coronavirus or COVID-19 diagnosis between 2019-2020. Diagnosis of PI following COVID-19 diagnosis was queried. Demographic data and comorbidity information was compared. Logistic regression analysis was used to determine predictors for both PI development and likelihood of operative debridement. RESULTS: A total of 1,477,851 patients with COVID-19 were identified. Of these, 15,613 (1.06%) subsequently developed a PI, and 8074 (51.7%) of these patients had an intensive care unit (ICU) admission. The average and median time between diagnosis of COVID-19 and PI was 39.4 and 26 days, respectively. PI was more likely to occur in patients with COVID-19 with: diabetes (odds ratio (OR): 1.39, 95% confidence interval (CI): 1.29-1.49; p<0.001); coronary artery disease (OR: 1.11, 95% CI: 1.04-1.18, p=0.002), hypertension (OR: 1.43, 95% CI: 1.26-1.64; p<0.001); chronic kidney disease (OR: 1.18, 95% CI: 1.10-1.26; p<0.001); depression (OR: 1.45, 95% CI 1.36-1.54; p<0.001); and long-term non-steroidal anti-inflammatory drug use (OR: 1.21, 95% CI: 1.05-1.40; p=0.007). They were also more likely in critically ill patients admitted to the ICU (OR: 1.40, 95% CI: 1.31-1.48; p<0.001); and patients requiring vasopressors (OR:1.25, 95% CI: 1.13-1.38; p<0.001), intubation (OR: 1.21, 95% CI 1.07-1.39; p=0.004), or with a diagnosis of sepsis (OR: 2.38, 95% CI 2.22-2.55; p<0.001). ICU admission, sepsis, buttock and lower back PI along with increasing Charlson Comorbidity Index (CCI) (OR: 1.04, 95% CI 1.00-1.08; p=0.043) was associated with surgical debridement. The vast majority of patients with COVID-19 did not undergo operative debridement or wound coverage. CONCLUSION: PIs are widely prevalent in patients with COVID-19, especially in those who are critically ill, yet the vast majority do not undergo operative procedures.

Nursing care in patients with dependency-related skin injuries in the community: a scoping review.

PURPOSE: Dependency-related skin injuries (DRSI) occur in people who need a high level of support to carry out day-to-day activities. Owing to the ageing population, the number of people at risk of DRSI is increasing. Most wound care is performed by nurses in the community. This scoping review aimed to identify the extent of literature on nursing care for patients with or at risk of developing DRSI living in their own home. MATERIALS AND METHODS: A scoping review was conducted. RESULTS: A total of 28 studies met the inclusion criteria and four main themes emerged: features of the community setting; wound types, causes and management; prevention strategies around aetiology and holistic care; care management and local wound care. CONCLUSION: Although most wounds occur in and are treated in the community, there is a paucity of research on wounds in this setting. The care of patients with DRSI in the community is complex and prevention according to the individual aetiology of each lesion is the key factor in wound care.
