Pressure ulcer risk assessment in the ICU. Is it time for a more objective measure?

BACKGROUND: The Braden scale, one of the most widely used risk assessment tools is often criticized when used in the Intensive Care Unit. Most patients in the Intensive Care Unit are at risk of pressure ulcer development meaning that the Braden score will usually indicate high risk for these patients. This study set out to determine the correlation between Sub-Epidermal Moisture measurements and Braden scores among Intensive Care Unit patients. METHODS: This study employed an observational research design. Braden score was assessed on all study days (1-5), in addition to visual skin assessment and Sub-Epidermal Moisture measurements at the sacrum and heels. Sub-Epidermal Moisture measurements were categorised as low (<0.5), borderline abnormal (≥0.5), and high (≥0.8). Correlation was assessed between Sub-Epidermal Moisture levels and Braden scores. RESULTS: A total of 53 participants were recruited. The median (interquartile range) baseline Braden score was 9 (9-10) and 81 % (n = 43) of participants were at very high/high risk of pressure ulcer development. Braden scores remained relatively constant over time with little fluctuation in scores. 19 % (n = 10) of patients had normal (<0.5) Sub-Epidermal Moisture delta measurements on enrolment, and all developed abnormal measurements by day 2. There were no significant correlations between Braden scores and Sub-Epidermal Moisture measurements. CONCLUSION: Although this was not its original intention, a missing link with the Braden scale is that it does not provide information on how patients are responding to the adverse effects of pressure and shear forces. Furthermore, in patients who are critically unwell, most patients are classified as being "at risk" of pressure ulcer development. Therefore, an objective measure of how patients are responding to pressure and shear forces at different anatomical areas is needed. IMPLICATIONS TO CLINICAL PRACTICE: Sub-Epidermal Moisture measurements can offer more information, not only on identifying those who are at risk, but also how those patients are tolerating this risk at different anatomical sites.

Assessing the healthcare costs associated with venous leg ulcer compression bandages - A scoping review.

AIM: To determine the monetary costs identified in economic evaluations of treatment with compression bandages among adults with venous leg ulcers (VLU). METHOD: A scoping review of existing publications was conducted in February 2023. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. RESULTS: Ten studies met the inclusion criteria. To place the costs of treatment into context, these are reported in conjunction with the healing rates. Three comparisons were made: 1.4 layer compression versus no compression (3 studies). One study reported that 4 layer compression was more expensive than usual care (£804.03 vs £681.04, respectively), while the 2 other studies reported the converse (£145 vs £162, respectively) and all costs (£116.87 vs £240.28 respectively). Within the three studies, the odds of healing were statistically significantly greater with 4 layer bandaging (OR: 2.20; 95% CI: 1.54-3.15; p = 0.001).; 2.4 layer compression versus other compression (6 studies). For the three studies reporting the mean costs per patient associated with treatment (bandages alone), over the treatment period, analysis identified a mean difference (MD) in costs for 4 layer vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) of -41.60 (95% CI: 91.40 to 8.20; p = 0.10). The OR of healing for 4 layer compression vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 0.70 (95% CI: 0.57-0.85; p = 0.004). For 4 layer vs comparator 2 (2 layer compression) the MD is: 14.00 (95% CI: 53.66 to -25.66; p < 0.49). The OR of healing for 4 layer compression vs comparator 2 (2 layer compression) is: 3.26 (95% CI: 2.54-4.18; p < 0.00001). For comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) vs comparator 2 (2 layer compression) the MD in costs is: 55.60 (95% CI: 95.26 to -15.94; p = 0.006). The OR of healing with Comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 5.03 (95% CI:4.10-6.17; p < 0.00001). Three studies presented the mean annual costs per patient associated with treatment (all costs). The MD is 172 (150-194; p = 0.401), indicating no statistically significant difference in costs between the groups. All studies showed faster healing rates in the 4 layer study groups. 3. Compression wrap versus inelastic bandage (one study). Compression wrap was less expensive than inelastic bandage (£201 vs £335, respectively) with more wounds healing in the compression wrap group (78.8%, n = 26/33; 69.7%, n = 23/33). CONCLUSION: The results for the analysis of costs varied across the included studies. As with the primary outcome, the results indicated that the costs of compression therapy are inconsistent. Given the methodological heterogeneity among studies, future studies in this area are needed and these should use specific methodological guidelines to generate high-quality health economic studies.

Costing pressure ulcer care in an Irish acute care setting: a feasibility study.

OBJECTIVE: To test the feasibility of using a standardised data collection tool to estimate the cost of stage 2-4 pressure ulcer (PU) care within an acute care setting. METHOD: Data on resource use and cost were obtained through a retrospective survey of nursing and medical notes collecting cost data for individual patients who received care for stage 2-4 PUs. RESULTS: Data for 20 patients (12 male/8 female) were analysed. The average patient age was 69 years (range: 37-95 years). Of this sample, seven patients had hospital-acquired PUs (HAPUs) and 14 patients had community-acquired PUs (CAPU) (one patient had both-in different anatomical areas). Over half of the total sample (55%; n=11) had a stage 2 PU. The average length of stay was 31.8 days (range: 5-119 days). Most of the patients (70%; n=14) had a CAPU. The average cost per patient with PU care was €878 (range: €39-2393). The mean cost for patients with a HAPU was €866 (SD: €1313) versus €911 (SD: €567) for patients with a CAPU. The majority of the cost related to equipment and staff time for treatment. CONCLUSION: Overall, the application of the standardised data collection tool to obtain cost data from retrospective inspection of nursing and medical notes is feasible. The cost of PU care in this sample was high, indicating that these wounds may impose a substantial burden on health systems. The costs varied greatly between patients in the sample, reflecting the complexity of PU care. Furthermore, given that costs increased with the higher PU stages, there is a potential to reduce costs by preventing the development of higher stage PUs. Larger-scale studies are required to understand the cost variation and full economic impact of PU care. DECLARATION OF INTEREST: The authors have no conflicts of interest.

'First tonight, the contentious new code telling nurses to say, 'sorry for being white': Mental health nurses' beliefs about their Code of Conduct and cultural safety for Aboriginal and Torres Strait Islander Peoples.

The Nursing and Midwifery Board of Australia's Code of Conduct for Nurses sets out the professional behaviour and conduct expectations for nurses in all practice settings. The publication of a revised version in 2018, which included expectations related to culturally safe and respectful practice and Aboriginal and Torres Strait Islander Peoples' health, caused reverberations beyond the profession of nursing. A controversy that the changes required nurses to verbally apologize for being white before their interactions with Aboriginal and Torres Strait Islander people gained the attention of the mainstream media. This interpretation, which came from outside nursing, was disputed by the Board. Challenged by these events, the authors were interested in understanding the actual impacts of the changes from the perspectives of nurses in practice. This research, carried out nearly three years after publication, has focused specifically on the speciality of mental health nurses in this context. The objective of this research was to undertake a social analysis focused on the impact that changes in the Code have had on the culture of mental health nursing utilizing a qualitative methodology. Eight mental health nurses were interviewed. The research found that there was little evidence of any impact on mental health nursing practice. Many of the participants were unaware of the amendments to the Code, whilst those nurses who were aware did not perceive that it had led to any real change within mental health nursing or service delivery.

Mental health nursing practice and Aboriginal and Torres Strait Islander people: an integrative review.

Background: For nearly thirty years, significant concerns have been raised about the public-provided mental health services for Aboriginal and Torres Strait Islander peoples. Staff have been identified as having little understanding of Indigenous culture, and this had resulted in inappropriate treatment. In attempting to understand what specialist knowledge exists to guide mental health nursing practice with Aboriginal and Torres Strait Islander peoples, the authors have turned to published peer-reviewed literature.Methods: The approach chosen to explore this area was an integrative review. This provided a method to identify, analyse, and synthesise a wide range of literature.Results: The available evidence points to the need that treatment planning must be focused on the promotion of social and emotional wellbeing and not simply the treatment of symptoms. It also emphasises the importance of cultural safety informed by awareness and understanding of social, cultural and historical factors that can impact the health and treatment of Aboriginal and Torres Strait Islander peoples. Within the literature, staff reported difficulty in understanding how knowledge about social and emotional wellbeing could translate into practice. Nurses working in mental health contexts reported not feeling adequately prepared for, or confident in this area of practice.Conclusions: There is a paucity of current literature on mental health nursing practice for Aboriginal and Torres Strait Islander peoples, with the literature available not providing clear guidance for effective and meaningful practice.

The economic impact of pressure ulcers among patients in intensive care units. A systematic review.

BACKGROUND: The incidence and prevalence of pressure ulcers in critically ill patients in intensive care units (ICUs) remain high, despite the wealth of knowledge on appropriate prevention strategies currently available. METHODS: The primary objective of this systematic review was to examine the economic impact of pressure ulcers (PU) among adult intensive care patients. A systematic review was undertaken, and the following databases were searched; Medline, Embase, CINAHL, and The Cochrane Library. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was used to formulate the review. Quality appraisal was undertaken using the Consensus on Health Economic Criteria (CHEC)-list. Data were extracted using a pre-designed extraction tool, and a narrative analysis was undertaken. RESULTS: Seven studies met the inclusion criteria. Five reported costs associated with the prevention of pressure ulcers and three explored costs of treatment strategies. Four main PU prevention cost items were identified: support surfaces, dressing materials, staff costs, and costs associated with mobilisation. Seven main PU treatment cost items were reported: dressing materials, support surfaces, drugs, surgery, lab tests, imaging, additional stays and nursing care. The overall validities of the studies varied between 37 and 79%, meaning that there is potential for bias within all the included studies. CONCLUSION: There was a significant difference in the cost of PU prevention and treatment strategies between studies. This is problematic as it becomes difficult to accurately evaluate costs from the existing literature, thereby inhibiting the usefulness of the data to inform practice. Given the methodological heterogeneity among studies, future studies in this area are needed and these should use specific methodological guidelines to generate high-quality health economic studies.

Laboratory Assessment of a Headband-Mounted Sensor for Measurement of Head Impact Rotational Kinematics.

Head impact sensors measure head kinematics in sports, and sensor accuracy is crucial for investigating the potential link between repetitive head loading and clinical outcomes. Many validation studies mount sensors to human head surrogates and compare kinematic measures during loading from a linear impactor. These studies are often unable to distinguish intrinsic instrumentation limitations from variability caused by sensor coupling. The aim of the current study was to evaluate intrinsic sensor error in angular velocity in the absence of coupling error for a common head impact sensor. Two Triax SIM-G sensors were rigidly attached to a preclinical rotational injury device and subjected to rotational events to assess sensor reproducibility and accuracy. Peak angular velocities between the SIM-G sensors paired for each test were correlated (R2 > 0.99, y = 1.00x, p < 0.001). SIM-G peak angular velocity correlated with the reference (R2 = 0.96, y = 0.82x, p < 0.001); however, SIM-G underestimated the magnitude by 15.0% ± 1.7% (p < 0.001). SIM-G angular velocity rise time (5% to 100% of peak) correlated with the reference (R2 = 0.97, y = 1.06x, p < 0.001) but exhibited a slower fall time (100% to 5% of peak) by 9.0 ± 3.7 ms (p < 0.001). Assessing sensor performance when rigidly coupled is a crucial first step to interpret on-field SIM-G rotational kinematic data. Further testing in increasing biofidelic conditions is needed to fully characterize error from other sources, such as coupling.

Helmet Fit Assessment and Concussion Risk in Youth Ice Hockey Players: A Nested Case-Control Study.

CONTEXT: Injury surveillance has shown that concussions are the most common injury in youth ice hockey. Research examining the criteria for ensuring the correct fit of protective equipment and its potential relationship with concussion risk is very limited. OBJECTIVE: To evaluate the association between helmet fit and the odds of experiencing a concussion among youth ice hockey players. DESIGN: Nested case-control within a cohort study. SETTING: Calgary, Alberta, Canada. PATIENTS OR OTHER PARTICIPANTS: Data were collected for 72 concussed, 41 nonconcussion-injured, and 62 uninjured ice hockey players aged 11 to 18 years. MAIN OUTCOME MEASURE(S): Helmet-fit assessments were conducted across players and encompassed helmet specifications, condition, certification, and criteria measuring helmet fit. Using a validated injury-surveillance system, we identified participants as players with suspected concussions or physician-diagnosed concussions or both. One control group comprised players who sustained nonconcussion injuries, and a second control group comprised uninjured players. Helmet-fit criteria (maximum score = 16) were assessed for the concussed players and compared with each of the 2 control groups. The primary outcome was dichotomous (>1 helmet-fit criteria missing versus 0 or 1 criterion missing). Logistic and conditional logistic regression were used to investigate the effect of helmet fit on the odds of concussion. RESULTS: The primary analysis (54 pairs matched for age, sex, and level of play) suggested that inadequate helmet fit (>1 criterion missing) resulted in greater odds of sustaining a concussion when comparing concussed and uninjured players (odds ratio [OR] = 2.67 [95% CI = 1.04, 6.81], P = .040). However, a secondary unmatched analysis involving all participants indicated no significant association between helmet fit and the odds of sustaining a concussion when we compared concussed players with nonconcussion-injured players (OR = 0.98 [0.43, 2.24], P = .961) or uninjured players (OR = 1.66 [0.90, 3.05], P = .103). CONCLUSIONS: Inadequate helmet fit may affect the odds of sustaining a concussion in youth ice hockey players. Future investigators should continue to evaluate this relationship in larger samples to inform helmet-fit recommendations.

Sub-epidermal moisture measurement: an evidence-based approach to the assessment for early evidence of pressure ulcer presence.

This paper aims to discuss the literature pertaining to early pressure-shear induced tissue damage detection, with emphasis on sub-epidermal moisture measurement (SEM). The current method for pressure detection is visual skin assessment (VSA); however, this method is fraught with challenges. Advances in early detection of pressure ulcers are reported in the literature and mainly involve measuring inflammation markers on weight-bearing anatomical areas in order to capture the first signs of tissue damage. One novel technique currently in use is SEM measurement. This biophysical marker is the product of plasma that leaks as a response to local inflammation arising due to pressure-shear induced damage over bony prominences. The early detection of tissue damage is beneficial in two different ways. First, it enables early intervention when the damage is still microscopic and reversible and, therefore, has the potential to prevent further aggravation of healthy surrounding tissue. This arises by avoiding the causation of the problem and stopping the knock-on effect of inflammation, especially when the rapid pressure ulceration pathway of deformation is in place. Second, when the slow ischaemic-reperfusion related mechanism is undergoing, cell death can be avoided when the problem is identified before the cell reaches the "death threshold," completely averting a pressure ulcer.

Prevention of pressure ulcers among individuals cared for in the prone position: lessons for the COVID-19 emergency.

OBJECTIVE: Pressure ulcers (PUs) involve the destruction of skin and underlying tissue due to prolonged pressure and shear forces. These ulcers are painful and significantly reduce a person's quality of life. PUs are also expensive to manage and impact negatively on the achievement of cost-effective, efficient care delivery. METHOD: Prone positioning is a postural therapy that aims to enhance respiratory function through increasing oxygenation levels. In contemporary clinical practice, ventilation in the prone position is indicated for patients with severe acute respiratory distress syndrome. However, despite its advantages in terms of respiratory function, several studies have examined complications of prone position ventilation and have identified PUs (facial PUs as well as PUs on other weight-bearing areas of the body) as a frequent complication in patients who are already in a precarious medical situation. International data suggest that up to 57% of patients nursed in the prone position develop a PU. The aim of this clinical review is to identify and review evidence-based recommendations developed to facilitate the selection and application of preventive interventions aimed at reducing PU development in patients ventilated in the prone position. Given the current COVID-19 crisis, this review is timely as intensive care unit (ICU) patients with COVID-19 require ventilation in the prone position at a level that is disproportionate to the general intensive care population. Up to 28% of patients admitted to the ICU with confirmed infection due to severe COVID-19 are cared for in the prone position. The scope of this review is limited to adult individuals only. RESULTS: The skin assessment should be undertaken before proning and following positioning the patient back into the supine position. Although it is essential to keep the skin clean and moisturised, using pH-balanced cleansers, there is inconsistency in terms of the evidence to support the type of moisturiser. Use of positioning devices in addition to repositioning is recommended to offload pressure points on the face and body. Further, using dressings such as hydrocolloids, transparent film and silicone may be of benefit in decreasing facial skin breakdown. CONCLUSION: Given the importance of PU prevention in this cohort of patients, adopting a focused prevention strategy, including skin assessment and care, offloading and pressure redistribution, and dressings for prevention may contribute to a reduction in the incidence and prevalence of these largely preventable wounds.

Methodological approaches for assessing the cost of diabetic foot ulcers: a systematic literature review.

OBJECTIVE: To evaluate the methodological approaches used to assess the cost consequences of diabetic foot ulcers (DFUs) in published scientific papers. METHOD: A systematic literature search was conducted in PubMed, Embase, Scopus, Web of Science and CINAHL. English language papers reporting on the cost of DFUs were identified. Additionally, bibliographies were inspected to identify other relevant cost studies. Following the PRISMA guidance, the review identified the study design, epidemiological approach, analytical perspective and data collection approach in each of the included studies. RESULTS: Relatively few studies of the cost consequences of DFUs were found (n=27). Most studies were conducted in Western countries with only five studies from countries in Asia and Africa. The identified studies used different study designs, epidemiological approaches, data collection strategies, and data sources, which in turn made a systematic comparison of cost estimates difficult. Detailed descriptions of the applied costing method and other methodological aspects were often limited or absent. Many studies only reported costs from a health-care payer's perspective and disregarded the costs to patients, their families and wider society. CONCLUSION: The costs of DFUs have been assessed using a wide range of different methodological approaches often restricted to the healthcare payer's perspective. Therefore, the cost analyses may fail to consider the true societal costs of DFUs.

An assessment of the utility and functionality of wearable head impact sensors in Australian Football.

OBJECTIVES: To assess the utility and functionality of the X-Patch® as a measurement tool to study head impact exposure in Australian Football. Accuracy, precision, reliability and validity were examined. DESIGNS: Laboratory tests and prospective observational study. METHODS: Laboratory tests on X-Patch® were undertaken using an instrumented Hybrid III head and neck and linear impactor. Differences between X-Patch® and reference data were analysed. Australian Football players wore the X-Patch® devices and games were video-recorded. Video recordings were analysed qualitatively for head impact events and these were correlated with X-Patch® head acceleration events. Wearability of the X-Patch® was assessed using the Comfort Rating Scale for Wearable Computers. RESULTS: Laboratory head impacts, performed at multiple impact sites and velocities, identified significant correlations between headform-measured and device-measured kinematic parameters (p<0.05 for all). On average, the X-Patch®-recorded peak linear acceleration (PLA) was 17% greater than the reference PLA, 28% less for peak rotational acceleration (PRA) and 101% greater for the Head Injury Criterion (HIC). For video analysis, 118 head acceleration events (HAE) were included with PLA ≥30g across 53 players. Video recordings of X-Patch®-measured HAEs (PLA ≥30g) determined that 31.4% were direct head impacts, 9.3% were indirect impacts, 44.1% were unknown or unclear and 15.3% were neither direct nor indirect head impacts. The X-Patch® system was deemed wearable by 95-100% of respondents. CONCLUSIONS: This study reinforces evidence that use of the current X-Patch® devices should be limited to research only and in conjunction with video analysis.

Risk assessment tools for the prevention of pressure ulcers.

BACKGROUND: Use of pressure ulcer risk assessment tools or scales is a component of the assessment process used to identify individuals at risk of developing a pressure ulcer. Use of a risk assessment tool is recommended by many international pressure ulcer prevention guidelines, however it is not known whether using a risk assessment tool makes a difference to patient outcomes. We conducted a review to provide a summary of the evidence pertaining to pressure ulcer risk assessment in clinical practice, and this is the third update of this review. OBJECTIVES: To assess whether using structured and systematic pressure ulcer risk assessment tools, in any healthcare setting, reduces the incidence of pressure ulcers. SEARCH METHODS: In February 2018 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase; and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing the use of structured and systematic pressure ulcer risk assessment tools with no structured pressure ulcer risk assessment, or with unaided clinical judgement, or RCTs comparing the use of different structured pressure ulcer risk assessment tools. DATA COLLECTION AND ANALYSIS: Two review authors independently performed study selection, data extraction, 'Risk of bias' assessment and GRADE assessment of the certainty of evidence. MAIN RESULTS: We included two studies in this review (1,487 participants). We identified no new trials for this latest update.Both studies were undertaken in acute-care hospitals. In one study, patients were eligible if they had a Braden score of 18 or less. In the second study all admitted patients were eligible for inclusion, once they were expected to have a hospital stay of more than three days and they had been in hospital for no more than 24 hours before baseline assessment took place. In the first study, most of the participants were medical patients; no information on age or gender distribution was provided. In the second study, 50.3% (619) of the participants were male, with a mean age of 62.6 years (standard deviation (SD): 19.3), and 15.4% (190) were admitted to oncology wards.The two included studies were three-armed studies. In the first study the three groups were: Braden risk assessment tool and training (n = 74), clinical judgement and training (n = 76) and clinical judgement alone (n = 106); follow-up was eight weeks. In the second study the three groups were: Waterlow risk assessment tool (n = 411), clinical judgement (n = 410) and Ramstadius risk assessment tool (n = 410); follow-up was four days. Both studies reported the primary outcome of pressure ulcer incidence and one study also reported the secondary outcome, severity of new pressure ulcers.We are uncertain whether use of the Braden risk assessment tool and training makes any difference to pressure ulcer incidence, compared to risk assessment using clinical judgement and training (risk ratio (RR) 0.97, 95% confidence interval (CI) 0.53 to 1.77; 150 participants), or compared to risk assessment using clinical judgement alone (RR 1.43, 95% CI 0.77 to 2.68; 180 participants). We assessed the certainty of the evidence as very low (downgraded twice for study limitations and twice for imprecision).Risk assessment using the Waterlow tool may make little or no difference to pressure ulcer incidence, or to pressure ulcer severity, when compared to risk assessment using clinical judgement (pressure ulcers of all stages: RR 1.10, 95% CI 0.68 to 1.81; 821 participants; stage 1 pressure ulcers: RR 1.05, 95% CI 0.58 to 1.90; 821 participants; stage 2 pressure ulcers: RR 1.25, 95% CI 0.50 to 3.13; 821 participants), or risk assessment using the Ramstadius tool (pressure ulcers of all stages: RR 1.41, 95% CI 0.83 to 2.39; 821 participants; stage 1 pressure ulcers: RR 1.16, 95% CI 0.63 to 2.15; 821 participants; stage 2 pressure ulcers: RR 2.49, 95% CI 0.79 to 7.89; 821 participants). Similarily, risk assessment using the Ramstadius tool may make little or no difference to pressure ulcer incidence, or to pressure ulcer severity, when compared to risk assessment using clinical judgement (pressure ulcers of all stages: RR 0.79, 95% CI 0.46 to 1.35; 820 participants; stage 1 pressure ulcers: RR 0.90, 95% CI 0.48 to 1.68; 820 participants; stage 2 pressure ulcers: RR 0.50, 95% CI 0.15 to 1.65; 820 participants). We assessed the certainty of the evidence as low (downgraded once for study limitations and once for imprecision).The studies did not report the secondary outcomes of time to ulcer development, or pressure ulcer prevalence. AUTHORS' CONCLUSIONS: We identified two studies which evaluated the effect of risk assessment on pressure ulcer incidence. Based on evidence from one study, we are uncertain whether risk assessment using the Braden tool makes any difference to pressure ulcer incidence, compared with training and risk assessment using clinical judgement, or risk assessment using clinical judgement alone. Risk assessment using the Waterlow tool, or the Ramstadius tool may make little or no difference to pressure ulcer incidence, or severity, compared with clinical judgement. The low, or very low certainty of evidence available from the included studies is not reliable enough to suggest that the use of structured and systematic pressure ulcer risk assessment tools reduces the incidence, or severity of pressure ulcers.

Analysis of Emergency Health Care Workforce and Service Readiness for a Mass Casualty Event in the Republic of Ireland.

OBJECTIVE: Ultimately, a country's capacity for a large-scale major emergency response will be directly related to the competence of its health care provider (HCP) workforce and communication between emergency responders and hospitals. The purpose of this study was to assess HCP preparedness and service readiness for a major emergency involving mass casualties (mass casualty event or MCE) in Ireland. METHODS: A cross-sectional study using a 53-item survey was administered to a purposive sample of emergency responders and HCPs in the Republic of Ireland. Data collection was achieved using the Qualtrics® Research Suite. Descriptive statistics and appropriate tests of comparison between professional disciplines were conducted using Stata 13. RESULTS: A total of 385 respondents, registered nurses (43.4%), paramedics (37.9%), medical doctors (10.1%), and administrators/managers (8.6%), participated in the study. In general, a level of knowledge of MCEs and knowledge of clinical response activities and self-assessed clinical competence varied drastically across many aspects of the survey. Knowledge and confidence also varied across professional disciplines (P<0.05) with nurses, in general, reporting the least knowledge and/or confidence. CONCLUSIONS: The results demonstrate that serious deficits exist in HCP knowledge, skills, and self-perceived abilities to participate in a large-scale MCE. Results also suggest a poor knowledge base of existing major emergency response plans. (Disaster Med Public Health Preparedness. 2019;13:243-255).

The relationship between nurses assessment of early pressure ulcer damage and sub epidermal moisture measurement: A prospective explorative study.

AIM: To explore the relationship between nurses' visual assessment of early pressure ulceration and assessment using sub epidermal moisture measurement (a measure of skin and tissue water). MATERIALS AND METHODS: A descriptive prospective observational study design was employed. Following ethical approval and written informed consent, data were collected daily, for four weeks, from at risk patients within an acute care facility in Ireland. Data included nurses documented assessment of the patient's skin condition and researcher led sub epidermal moisture measurement, over the sacrum and both heels. RESULTS: A total of 47 patients were included, 38.3% (n = 18) were male and 61.5% (n = 29) were female, with a mean age of 74.7 years. Nineteen patients (40%) developed 21 Stage 1 pressure ulcers and all of these had sustained elevated sub epidermal moisture (SEM) levels before visual signs of damage became evident indicating 100% sensitivity of SEM readings in predicting pressure ulceration. Specificity was 83% with the majority of false positives having insufficient follow-up time. Furthermore a medium correlation between nurses' visual skin assessment (the current gold standard in pressure ulcer detection) and SEM findings (r = .47; p = 0.001) was identified. The mean number of days for nurses to detect this damage was 5.5 (±2,5; max 11, min 2), whereas the mean number of days that it took SEM measurement to detect damage was 1.5 (±1.4; max 7, min 1). SEM measurement identified early damage, on average, 4 days sooner than nurses' assessment. CONCLUSION: Given that pressure ulcers develop from within the deeper tissues, knowing that early pressure ulcer damage is present can facilitate heightening of prevention strategies to avoid extension. This is of importance in clinical practice as the earlier that pressure ulcers can be detected; the earlier interventions can be implemented to prevent further extension, avoiding their associated morbidity and mortality.

Models of initial training and pathways to registration: a selective review of policy in professional regulation.

AIM: To provide a synthesis of literature on international policy concerning professional regulation in nursing and midwifery, with reference to routes of entry into training and pathways to licensure. BACKGROUND: Internationally, there is evidence of multiple points of entry into initial training, multiple divisions of the professional register and multiple pathways to licensure. EVALUATION: Policy documents and commentary articles concerned with models of initial training and pathways to licensure were reviewed. Item selection, quality appraisal and data extraction were undertaken and documentary analysis was performed on all retrieved texts. KEY ISSUES: Case studies of five Western countries indicate no single uniform system of routes of entry into initial training and no overall consensus regarding the optimal model of initial training. CONCLUSIONS: Multiple regulatory systems, with multiple routes of entry into initial training and multiple pathways to licensure pose challenges, in terms of achieving commonly-agreed understandings of practice competence. IMPLICATIONS FOR NURSING MANAGEMENT: The variety of models of initial training present nursing managers with challenges in the recruitment and deployment of personnel trained in many different jurisdictions. Nursing managers need to consider the potential for considerable variation in competency repertoires among nurses trained in generic and specialist initial training models.
