Although great strides have been made to tackle hospital-acquired pressure ulcers (HAPUs), there is a need for greater recognition of device-related pressure ulcers (DRPUs), including their causes, management and prevention. This consensus statement, an updated second edition, aims to continue raising awareness of these largely preventable injuries and, crucially, to stimulate action. DRPUs are relatively common and account for a growing proportion of HAPUs. Updated information on the incidence of DRPUs is described in chapter 1. Although it is recognised that DRPUs increase the financial burden of healthcare, there is little formal analysis of their economic impact. This needs to be addressed; robust evidence on the burden of DRPUs and the value that can be released by adopting prevention strategies is needed to help drive action. Our understanding of the pathophysiology of DRPUs has improved significantly over the past few years; this is described in chapter 2. One crucial difference between PUs and DRPUs is that body-weight forces are less significant in DRPUs, with the force being exerted from a device that is typically strapped or taped onto the body. Devices and their securement may generate high stress concentrations in tissues, leading to cell and tissue-damage pathways associated with sustained deformation. As more evidence is published on DRPUs, recurring themes are emerging, as outlined in chapter 3: The most vulnerable patients are bearing the brunt of DRPUs; paediatric and neonatal patients, and all those needing critical care are particularly susceptible. During the COVID-19 pandemic, a new high-risk population (people with severe COVID-19 infection) emerged. They are at increased risk of DRPUs because of their need for prolonged ventilatory support, especially when 'proning' Devices associated with DRPUs are often used to perform essential, life-saving functions. They include continuous positive airway pressure (CPAP) masks or endotracheal tubes. Minimising their use is clearly not an option, so practice innovation is needed Although the most common locations for DRPUs are the face, ears, lower legs and heels, any location where a device comes into close contact with the skin can be at risk. In the same vein, any device, whether needed for a medical purpose or not, has the capacity to cause injury if its use is not properly managed. Vigilance is needed for all patients. What can be done? The importance of routine risk assessment is covered in chapter 4. Although use of a validated risk assessment tool is the vital first step, this will not be enough on its own. Several steps can be taken to ensure the safe use of devices. These are described in chapter 5 and include device repositioning, cushioning with prophylactic dressings and moisture control (only where possible and clinically appropriate). Of key importance is the development of an institutional protocol and champions to ensure all necessary steps are adopted. For any of these changes to be put into practice, awareness of DRPUs needs to increase. A number of proposals are outlined in chapter 6. A change of focus among health professionals and policy makers, along with more investment in education and training, are needed. All patients being managed with a medical device must be considered as at high risk. The pandemic introduced the world to the problem of DRPUs in health professionals caused by the extended wear of personal protective equipment. Health professionals also have a right to expect institutional protocols and provision of devices that protect them from DRPUs. Cutting-edge ideas and technologies that may be available in the future are described in chapter 7. When designing new products, manufacturers of medical devices have a duty of care to investigate the risks of DRPUs associated with their products and mitigate them, wherever possible. Our developing understanding of how the design, structure and materials used in medical devices contribute to DRPUs will help us develop new solutions for tomorrow. The first step is for everyone involved to ask themselves, 'what can I do to help?' There is work to be done-your journey to reduce DRPUs starts here!.

Catherine Milne and colleagues present the findings of their review, ccna2@juno.com.

Purpose: This systematic review paper aims to investigate seasonal ambient change's impact on the incidence of falls among older adults. Design/methodology/approach: The population, exposure, outcome (PEO) structured framework was used to frame the research question prior to using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. Three databases were searched, and a total of 12 studies were found for inclusion, and quality appraisal was carried out. Data extraction was performed, and narrative analysis was carried out. Findings: Of the 12 studies, 2 found no link between seasonality and fall incidence. One study found fall rates increased during warmer months, and 9 of the 12 studies found that winter months and their associated seasonal changes led to an increase in the incidence in falls. The overall result was that cooler temperatures typically seen during winter months carried an increased risk of falling for older adults. Originality/value: Additional research is needed, most likely examining the climate one lives in. However, the findings are relevant and can be used to inform health-care providers and older adults of the increased risk of falling during the winter. [ABSTRACT FROM AUTHOR]

The aim of this study was to explore psychiatric nurse's experiences of caring for people with auditory hallucinations in an acute unit. A qualitative study was conducted using thematic analysis. The study involved semi‐structured interviews with 18 acute unit nurses all of whom provided interventions to patients with auditory hallucinations. Overall, participants identified their role in the management of risk within an acute unit, the importance of their therapeutic role and a perceived over‐reliance on medication administration as a primary nursing intervention. These findings thus demonstrate the personal and professional conflict that nurses face when working in an acute unit with patients who experience auditory hallucinations. Nurses are in a prime position to provide effective interventions and assistance for people with auditory hallucinations in an acute unit. The findings of this study indicate that mental health nurses may require additional support and education to provide care in a truly recovery‐based manner, with training in specific interventions and engagement skills for people who hear voices. Due to an unpredictable environment and sometimes high‐risk workplace, nurses may also benefit from organisational assistance in this area. [ABSTRACT FROM AUTHOR]

Background: Traumatic brain injuries (TBIs) are one of the leading causes of death or long‐term disability around the world. As a result of improvements in supportive care, patients are surviving more severe insults with more pronounced dependency on their families, hospitals, and long‐term care facilities. The introduction of brain tissue oxygenation (PbtO2) monitoring aims to recognize episodes of reduced cerebral perfusion with and without associated increased intracranial pressure (ICP). Aim: The aim of this review is to determine the impact of PbtO2 on the Glasgow Outcome Scale/Glasgow Outcome Scale Extended (GOS/GOSE) in patients with moderate to severe TBI. Study Design: Systematic review with narrative and meta‐analysis. All original research in which adult patients undergoing PbtO2 were compared with a control group of traditional ICP/cerebral perfusion pressure (CPP) monitoring. Both randomized controlled trials and observational studies were included in this review. Methods: Databases were searched in September 2022. The primary outcome of the review was the impact of PbtO2 monitoring on GOS/GOSE, while secondary outcomes were mortality and length of stay (LOS) in the intensive care unit (ICU). Results: Seven studies with a combined number of 770 patients were included in the review. These patients were adults ≥16 years of age. Only two of the studies included found a statistically significant association between PbtO2 monitoring and improved long‐term neurological outcomes in patients with TBI (p =.01, p <.01). A meta‐analysis of the secondary outcomes identified an associated reduction of mortality in favour of the group treated with PbtO2 monitoring (p <.0001). Results from studies examining LOS in ICU have demonstrated an associated increase of LOS in ICU in patients treated with PbtO2‐guided therapy. Conclusion: From the studies included in this review, only two found a statistically significant association between PbtO2 monitoring and long‐term outcomes. It is unclear whether PbtO2 goal‐directed therapy has a positive impact on the long‐term neurological functions and mortality of patients suffering from TBI. A multicentre randomized controlled trial may provide further evidence, but not necessarily conclusive. Relevance to Clinical Practice: Further research is warranted to determine the efficacy of the introduction of this new monitoring system to guide local policy change. [ABSTRACT FROM AUTHOR]

Aim: To determine the impact of home‐based management on hospital re‐admission rates in patients with chronic obstructive pulmonary disease (COPD). Design: Systematic review methodology was utilized, combining meta‐analysis, where appropriate, or a narrative analysis of the data from included studies. Data Sources: Electronic databases CINAHL, MEDLINE, PubMed, Embase and SAGE journals for primary papers, 2015 to 2021, were searched between December 2020 and March 2021, followed by hand‐searching key journals, and reference lists of retrieved papers. Methods: The review followed the guidance of PRISMA. Data were extracted using a predesigned data extraction tool. Quality appraisal was undertaken using RevMan 'risk of bias' tool. Meta‐analysis was undertaken using RevMan software. Results: This review integrates evidence from eight studies, five Random Control Trials, two observational studies and one retrospective study. The studies span three continents, Asia, Europe and North America, and include 3604 participants with COPD. Home‐based management in patients with COPD resulted in a statistically significant reduction in rates of hospital readmission. For the outcomes, length of stay and mortality, while slightly in favour of home‐based management, the results were not statistically significant. Conclusion: Given the burden of COPD on healthcare systems, and crucially on individuals, this review identified a reduction in hospital re‐admission rate, a clinically important outcome. Impact: This study focused on the impact on hospital re‐admission rates among the COPD patient cohort when home‐based management was involved. A statistically significant reduction in rates of re‐admission to the hospital was identified. This is positive for the patient, in terms of hospital avoidance, and reduces the burden on hospital systems. Further research is needed to determine the impact on cost‐effectiveness and to quantify the most ideal type of care package that would be recommended for home‐based management.

There is growing interest in the roles of temperature, epidermal hydration (EH) and pain in pressure ulcer (PU) development. Investigating correlations between these measures and sub‐epidermal moisture (SEM) will address this knowledge deficit. A prospective observational study enrolled 60 surgical patients from February to November 2021. SEM, temperature, EH and pain were assessed using a SEM scanner, thermography imaging, skin hydration device and numeric pain intensity scale, respectively. Measurements were taken at the sacrum, both heels and a control site, before and after surgery for 3 days. Data were analysed using Pearson or Spearman's correlation. Of the participants, 50% were male with a mean age of 58 years (±13.46). Low positive/negative correlations between SEM and temperature were found at the sacrum. However, after removing outliers, these results were not statistically significant. Other sites and follow‐up days showed negligible correlations. No evidence of a correlation, to low correlations between SEM and EH were observed, but unreliable due to little variation in EH at the heels. Pain showed negligible correlations with SEM. This study did not find consistent evidence of a correlation between SEM, temperature, EH and pain, highlighting the unreliability of temperature and EH for early PU detection. Post‐operative pain may also confound accurate pain assessments. [ABSTRACT FROM AUTHOR]

This commentary considers the similarities which exist between pressure ulcers (PUs) and diabetic foot ulcers (DFUs). It aims to describe what is known to be shared—both in theory and practice—by these wound types. It goes on to detail the literature surrounding the role of inflammation in both wound types. PUs occur following prolonged exposure to pressure or pressure in conjunction with shear, either due to impaired mobility or medical devices. As a result, inflammation occurs, causing cell damage. While DFUs are not associated with immobility, they are associated with altered mobility occurring as a result of complications of diabetes. The incidence and prevalence of both types of lesions are increased in the presence of multimorbidity. The prediction of either type of ulceration is challenging. Current risk assessment practices are reported to be ineffective at predicting when ulceration will occur. While systemic inflammation is easily measured, the presence of local or subclinical inflammation is harder to discern. In patients at risk of either DFUs or PUs, clinical signs and symptoms of inflammation may be masked, and systemic biomarkers of inflammation may not be elevated sufficiently to predict imminent damage until ulceration appears. The current literature suggests that the use of local biomarkers of inflammation at the skin's surface, namely oedema and temperature, may identify early tissue damage. [ABSTRACT FROM AUTHOR]

Pressure ulcers (PU) are a globally recognised healthcare concern, with their largely preventable development prompting the implementation of targeted preventive strategies. Risk assessment is the first step to planning individualised preventive measures. However, despite the long use of risk assessment, and the >70 risk assessment tools currently available, PUs remain a significant concern. Various technological advancements, including artificial intelligence, subepidermal moisture measurement, cytokine measurement, thermography and ultrasound are emerging as promising tools for PU detection, and subsequent prevention of more serious PU damage. Given the rise in availability of these technologies, this advances the question of whether our current approaches to PU prevention can be enhanced with the use of technology. This article delves into these technologies, suggesting that they could lead healthcare in the right direction, toward optimal assessment and adoption of focused prevention strategies.
