Global prevalence and incidence of pressure injuries in hospitalised adult patients: A systematic review and meta-analysis

Investigation of related factors of operating room nurses' attitudes and awareness towards surgery-related pressure injury prevention in Turkey, Croatia, and Italy

OBJECTIVE

The aim of this study is to examine related factors of operating room nurses' attitudes and awareness towards surgery-related pressure injury prevention in Turkey, Croatia, and Italy.

METHODS

A descriptive and cross-sectional design was used. The study was conducted between March and September 2023. Data were collected with an online questionnaire created on Google Forms, consisting of a Nurse Information Form, a Surgery-related Pressure Injury Awareness Form, and the Attitude towards Pressure Ulcer Prevention Instrument.

RESULTS

The sample of the study consisted of 258 operating room nurses working in Turkey, Croatia, and Italy. It was found that the majority of the participants (70.90 %) did not use a risk scale, had not received education on pressure injury prevention and treatment (58.10 %) but wanted to receive it (86 %). Mean attitude scores of operating room nurses by country were at an adequate level in Turkey (42.48 ± 4.30) but not at the desired level in Croatia (37.48 ± 3.44) and Italy (36.20 ± 4.02). While there was a significant positive relationship between the awareness and attitudes of operating room nurses in Turkey (p = 0.002) and Croatia (p < 0.001), no relationship was found between these variables of nurses in Italy (p = 0.109). A statistically significant difference was found between nurses' consideration of themselves sufficient and their attitudes and awareness in all three countries (p < 0.05). It was also determined that reading articles affected nurses' awareness in all countries.

CONCLUSIONS

While operating room nurses' attitudes towards preventing pressure injuries were adequate in Turkey, it was determined that those of the nurses in Croatia and Italy were not at the desired level. Nurses should receive regular training on surgical pressure injuries to increase their awareness and to support them in implementing the recommendations of pressure injury guidelines in accordance with institutional policy.

The influence of the online education provided using the six thinking hat method on the knowledge and attitudes of nursing students regarding pressure injury prevention; a pilot study

AIM

The study aims to investigate the influence of the online education given to nursing undergraduate students using the Six Thinking Hat Method (STHM) on their knowledge and attitudes related to pressure injury (PI) prevention.

METHODS

This pilot study was conducted between March-June 2023. The research sample consists of 25 participants in the intervention group and 25 in the control group. The intervention group received an online education carried out utilizing the STHM. Data were collected using the Student Demographic Information Form, the Turkish version of the Pressure Injury Knowledge Assessment Tool 2.0 (PIKAT 2.0-Tr), and the Attitude Towards the Pressure Ulcer Prevention Instrument (APuP).

RESULTS

While there was no significant difference between the PIKAT 2.0-Tr and APuP mean scores of the groups at the pre-test measurements (p > 0.05), a difference was observed in favor of the intervention group in the first month (post-test 1) and third month (post-test 2) measurements (p < 0.05). The education provided through the STHM resulted in a meaningful and moderate effect, with an 11.7% increase in the PIKAT 2.0-Tr scores (η2 = 0.117; p = 0.003) and a substantial 29.5% increase in the APuP scores (η2 = 0.295; p = 0.000) for the students in the intervention group.

CONCLUSION

It has been determined that the STHM, as an active teaching method, increases students' knowledge levels on PI prevention, supports the retention of knowledge, and enhances their attitudes. The STHM can be incorporated into nursing education as one of the innovative teaching methods.

Evaluation of the risk prediction model of pressure injuries in hospitalized patient: A systematic review and meta-analysis

AIMS AND OBJECTIVES

The main aim of this study is to synthesize the prevalent predictive models for pressure injuries in hospitalized patients, with the goal of identifying common predictive factors linked to pressure injuries in hospitalized patients. This endeavour holds the potential to provide clinical nurses with a valuable reference for providing targeted care to high-risk patients.

BACKGROUND

Pressure injuries (PIs) are a frequently occurring health problem throughout the world. There are mounting studies about risk prediction model of PIs reported and published. However, the prediction performance of the models is still unclear.

DESIGN

Systematic review and meta-analysis: The Cochrane Library, PubMed, Embase, CINAHL, Web of Science and Chinese databases including CNKI (China National Knowledge Infrastructure), Wanfang Database, Weipu Database and CBM (China Biology Medicine).

METHODS

This systematic review was conducted following PRISMA recommendations. The databases of Cochrane Library, PubMed, Embase, CINAHL, Web of Science, and CNKI, Weipu Database, Wanfang Database and CBM were searched for all studies published before September 2023. We included studies with cohort, case-control designs, reporting the development of risk model and have been validated externally and internally among the hospitalized patients. Two researchers selected the retrieved studies according to the inclusion and exclusion criteria, and critically evaluated the quality of studies based on the CHARMS checklist. The PRISMA guideline was used to report the systematic review and meta-analysis.

RESULTS

Sixty-two studies were included, which contained 99 pressure injuries risk prediction models. The AUC (area under ROC curve) of modelling in 32 prediction models were reported ranged from .70 to .99, while the AUC of verification in 38 models were reported ranged from .70 to .98. Gender (OR = 1.41, CI: .99 ~ 1.31), age (WMD = 8.81, CI: 8.11 ~ 9.57), diabetes mellitus (OR = 1.64, CI: 1.36 ~ 1.99), mechanical ventilation (OR = 2.71, CI: 2.05 ~ 3.57), length of hospital stay (WMD = 7.65, CI: 7.24 ~ 8.05) were the most common predictors of pressure injuries.

CONCLUSION

Studies of PIs risk prediction model in hospitalized patients had high research quality, and the risk prediction models also had good predictive performance. However, some of the included studies lacked of internal or external validation in modelling, which affected the stability and extendibility. The aged, male patient in ICU, albumin, haematocrit, low haemoglobin level, diabetes, mechanical ventilation and length of stay in hospital were high-risk factors for pressure injuries in hospitalized patients. In the future, it is recommended that clinical nurses, in practice, select predictive models with better performance to identify high-risk patients based on the actual situation and provide care targeting the high-risk factors to prevent the occurrence of diseases.

RELEVANCE TO CLINICAL PRACTICE

The risk prediction model is an effective tool for identifying patients at the risk of developing PIs. With the help of risk prediction tool, nurses can identify the high-risk patients and common predictive factors, predict the probability of developing PIs, then provide specific preventive measures to improve the outcomes of these patients.

Student nurses' knowledge levels and attitudes regarding pressure injury prevention

OBJECTIVE

The research was conducted to examine the relationship between student nurses' knowledge levels and attitudes regarding pressure ulcer prevention.

METHOD

The research was registered between 01.05.2022 and 01.12.2022, and the certification studies of the health sciences faculty of a state and a foundation university in Turkey are carried out on a multi-center basis. The lists of the research were created by 426 student pictures. "Nurse Introduction Form", "Pressure Sore Prevention Information Survey" and "Attitude Scale towards Preventing Pressure Ulcers" were used as data collection tools. Data was collected online via Google Forms and the SPPS 24.0 program was evaluated in detail.

RESULTS

It was determined that the PIPK total score of Student Certificates was 18.29 ± 5.98, and the total score of APUP was 33.96 + 4.66. The change analysis results revealed positive aspects and a low-level significant relationship between the average nutrition total knowledge scores and the pressure prevention attitude total scores (p < 0.05).

CONCLUSION

In our study results, it was determined that the pressure values of the certificates and the knowledge scores of the students were insufficient and the attitudes were positive. The values of knowledge and attitudes regarding the nurturing of the values of certificates, starting from student life, states where the necessary knowledge and skills must be acquired in educational programs.

Self-Assembled Fibroblast Growth Factor Nanoparticles as a Therapeutic for Oxidant-Induced Neuronal and Skin Cell Injury

Traumatic brain injury (TBI) and spinal cord injury (SCI) are neurological conditions that result from immediate mechanical injury, as well as delayed injury caused by local inflammation. Furthermore, TBI and SCI often lead to secondary complications, including pressure wounds of the skin, which can heal slowly and are prone to infection. Pressure wounds are localized areas of damaged tissue caused by prolonged pressure on the skin due to immobility and loss of neurological sensation. With the aim to ameliorate these symptoms, we investigated whether fibroblast growth factors 2 (FGF-2) could contribute to recovery. FGF-2 plays a significant role in both neurogenesis and skin wound healing. We developed a recombinant fusion protein containing FGF-2 linked to elastin-like polypeptides (FGF-ELP) that spontaneously self-assembles into nanoparticles at around 33 °C. The nanoparticle's size was ranging between 220 and 250 nm in diameter at 2 μM. We tested this construct for its ability to address neuronal and skin cell injuries. Hydrogen peroxide was used to induce oxidant-mediated injury on cultured neuronal cells to mimic the impact of reactive oxidants released during the inflammatory response in vivo. We found that FGF-ELP nanoparticles protected against hydrogen peroxide-mediated injury and promoted neurite outgrowth. In the skin cell models, cells were depleted from serum to mimic the reduced levels of nutrients and growth factors in chronic skin wounds. FGF-ELP increased the proliferation and migration of human keratinocytes, fibroblasts, and endothelial cells. FGF-ELP is, therefore, a potentially useful agent to provide both neuroprotection and promotion of cellular processes involved in skin wound healing.

Assessment of perceived patient comfort and ease of bedpan handling by caregivers, a cross-sectional survey

INTRODUCTION

Since its creation in the 18th century, bedpan has remained more or less the same. Its unique material composition varies from one model to another, but its shape remains relatively similar. The environment is one of the four pillars of the nursing paradigm. It is therefore essential to question this device in the nursing discipline.

AIM

To assess perceived patient comfort and ease of bedpan handling by nurses and their assistants.

METHOD

A cross-sectional survey via an online questionnaire was conducted among nurses and nursing assistants, nursing students, and health executives using the bedpan for their patients to assess their feelings and their level of satisfaction. The questionnaire asks professionals about the ease of handling the bedpan and the patient's perceived comfort.

RESULTS

431 responses were obtained out of 3007 persons interviewed (14.3%). 83.0% believe that the cause of poor elimination by the patient is often or very often due to physical discomfort on the bedpan. 62.6% find the installation of the bedpan rather tough or very difficult. 59.2% find the removal of the bedpan rather tough or very difficult.

DISCUSSION

Our study confirms our hypothesis and highlights a lack of comfort in the bedpan as perceived by professionals. This analysis is the first step in enabling the nurse researcher to support change in the transformation paradigm.

Efficacy of sodium hypochlorite in overcoming antimicrobial resistance and eradicating biofilms in clinical pathogens from pressure ulcers

Sodium hypochlorite (NaOCl) is widely recognized for its broad-spectrum antimicrobial efficacy in skin wound care. This study investigates the effectiveness of NaOCl against a range of bacterial and fungal isolates from pressure ulcer (PU) patients. We analyzed 20 bacterial isolates from PU patients, comprising carbapenem-resistant Klebsiella pneumoniae (CRKP), multidrug-resistant Acinetobacter baumannii (MDRAB), methicillin-resistant Staphylococcus aureus (MRSA), methicillin-susceptible Staphylococcus aureus (MSSA), along with 5 Candida albicans isolates. Antibiotic resistance profiles were determined using standard susceptibility testing. Whole-genome sequencing (WGS) was employed to identify antimicrobial resistance genes (ARGs) and disinfectant resistance genes (DRGs). Genetic determinants of biofilm formation were also assessed. The antimicrobial activity of NaOCl was evaluated by determining the minimum inhibitory concentration (MIC) and the minimal biofilm eradication concentration (MBEC) for both planktonic and biofilm-associated cells. CRKP and MDRAB showed resistance to fluoroquinolones and carbapenems, while MRSA exhibited resistance to β-lactams and levofloxacin. MSSA displayed a comparatively lower resistance profile. WGS identified significant numbers of ARGs in CRKP and MDRAB, with fewer DRGs compared to MRSA and MSSA. All isolates possessed genes associated with fimbriae production and adhesion, correlating with pronounced biofilm biomass production. NaOCl demonstrated substantial antimicrobial activity against both planktonic cells and biofilms. The MIC90 for planktonic bacterial cells was 0.125 mg/mL, and the MBEC90 ranged from 0.225 to 0.5 mg/mL. For planktonic C. albicans, the MIC90 was 0.150 mg/mL, and the MBEC90 was 0.250 mg/mL. These results highlight the challenge in treating biofilm-associated infections and underscore the potential of NaOCl as a robust antimicrobial agent against difficult-to-treat biofilm infections at concentrations lower than those typically found in commercial disinfectants.

Combined treatment of umbilical cord Wharton's jelly-derived mesenchymal stem cells and platelet-rich plasma for a surgical patient with hospital-acquired pressure ulcer: a case report and literature review

Hospital-acquired pressure ulcers (HAPUs) are still an important worldwide issue related to the safety and quality of patient care, which are among the top five adverse events reported. Patients who develop HAPUs have longer stays in the hospital than necessary, are at a greater risk of infections, and are more likely to die. Surgical patients are prone to developing PUs because they often remain immobile for extended periods of time, and their surgical procedures may limit the flow of blood oxygen and nutrition and lead to a decrease in muscle tone. Mesenchymal stem cells (MSCs) represent an attractive stem cell source for tissue regeneration in clinical applications, which have been demonstrated to improve wound healing through re-epithelialization, increased angiogenesis, and granulation tissue formation. Here, we present the case of an emergency surgical patient who developed an ulcer on the right heel during hospitalization. The human umbilical cord Wharton's jelly-derived MSCs (WJ-MSCs) re-suspended in platelet-rich plasma (PRP) were injected into ulcer margins. Four days after the WJ-MSC application, the patient showed progressive healing of the PU. From days 4 to 33, granulation tissue formation and re-epithelialization were clearly observed. The ulcer was almost healed completely on day 47, and the pain in the patient's wound area also decreased. Thus, intradermal transplantation of WJ-MSCs and PRP was safe and effective for treatment in patients with pressure ulcers. WJ-MSCs, together with PRP, may offer a promising treatment option for wound healing.

Use of a risk-based intervention bundle to prescribe and implement interventions to prevent pressure injury: An observational study

AIM

To explore the relationship between the prescription and implementation of pressure injury preventative interventions following risk assessment combined with a risk-stratified intervention bundle.

DESIGN

Single-centre, cross-sectional, observational, prospective.

METHODS

The charts and bedsides of 341 adult inpatients were examined. Data collection included pressure injury risk level, prescribed preventative interventions and evidence of intervention implementation.

RESULTS

Most patients (68.6%) were at risk of pressure injury, and most interventions were prescribed according to their risk level. However, evidence from direct observation and/or documentation indicated intervention implementation rates were relatively poor. Of nine interventions mandated for all patients, compliance with three patient-/carer-focused interventions was particularly poor, with evidence indicating they had been implemented for 3%-10% of patients. Also, nutritional screening-related interventions were implemented poorly. Clinically indicated implementation of heel-elevation devices and bariatric equipment was low for at-risk patients, and the implementation of interventions for patients with existing pressure injuries was suboptimal. Significant proportions of several interventions that were observed as having been implemented were not documented as such.

CONCLUSION

While most interventions were prescribed according to patient risk level, the overall implementation of interventions was poor. However, the results may in part be due to failure to document interventions as opposed to omitting them.

IMPLICATIONS FOR PATIENT CARE

Documentation of interventions is crucial as it provides evidence of the care provided. An increased focus on documentation of pressure injury preventative interventions is required, with a clear distinction between prescription and implementation.

IMPACT

The results highlighted several deficiencies in care, particularly relating to evidence of implementation, patient involvement and nutritional screening. The results from this study will be used to inform and improve future pressure injury prevention practice within the study hospital and should be used to inform and benchmark pressure injury preventative practices in other hospitals.

REPORTING METHOD

The study adheres to STROBE guidelines.

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

TWEETABLE ABSTRACT

Pressure injury prevention care bundles decrease hospital-acquired pressure injuries, but the certainty of this evidence is very low.

Effects of a mattress cover with special airflow technology on the structure and function of the sacral and heel skin during loading: A two-arm exploratory crossover trial

Prolonged mechanical loading of the skin and underlying soft tissue cause pressure ulceration. The use of special support surfaces are key interventions in pressure ulcer prevention. They modify the degree and duration of soft tissue deformation and have an impact on the skin microclimate. The objective of this randomized cross-over trial was to compare skin responses and comfort after lying for 2.5 h supine on a support surface with and without a coverlet that was intended to assist with heat and moisture removal at the patient/surface interface. In addition, physiological saline solution was administered to simulate an incontinence episode on the mattress next to the participants' skin surface. In total, 12 volunteers (mean age 69 years) with diabetes mellitus participated. After loading, skin surface temperature, stratum corneum hydration and skin surface pH increased, whereas erythema and structural stiffness decreased at the sacral area. At the heel skin area, temperature, erythema, and stratum corneum hydration increased. These results indicate occlusion and soft tissue deformation which was aggravated by the saline solution. The differences in skin response showed only minor differences between the support surface with or without the coverlet.

Trends in inpatient burden from pressure injuries in the United States: Cross-sectional study National Inpatient Sample 2009-2019

Pressure injuries are a significant comorbidity and lead to increased overall healthcare costs. Several European and global studies have assessed the burden of pressure injuries; however, no comprehensive analysis has been completed in the United States. In this study, we investigated the trends in the burden of pressure injuries among hospitalised adults in the United States from 2009 to 2019, stratified by sociodemographic subgroups. The length of admission, total cost of hospitalisation, and sociodemographic data was extracted from the National Inpatient Sample provided by the Healthcare Cost and Utilisation Project, Agency for Healthcare Research and Quality. Overall, the annual prevalence of pressure injuries and annual mean hospitalisation cost increased ($69,499.29 to $102,939.14), while annual mean length of stay decreased (11.14-9.90 days). Among all races, minority groups had higher average cost and length of hospitalisation. Our findings suggest that while the length of hospitalisation is decreasing, hospital costs and prevalence are rising. In addition, differing trends among racial groups exist with decreasing prevalence in White patients. Further studies and targeted interventions are needed to address these differences, as well as discrepancies in racial groups.

Nurse-Sensitive Indicators as Predictors of Trauma Patient Discharge Disposition

BACKGROUND

About 3.5 million trauma patients are hospitalized every year, but 35%-40% require further care after discharge. Nurses' ability to affect discharge disposition by minimizing the occurrence of nurse-sensitive indicators (catheter-associated urinary tract infection [CAUTI], central line-associated bloodstream infection [CLABSI], and hospital-acquired pressure injury [HAPI]) is unknown. These indicators may serve as surrogate measures of quality nursing care.

OBJECTIVE

The purpose of this study was to determine whether nursing care, as represented by three nurse-sensitive indicators (CAUTI, CLABSI, and HAPI), predicts discharge disposition in trauma patients.

METHODS

This study was a secondary analysis of the 2021 National Trauma Data Bank. We performed logistic regression analyses to determine the predictive effects of CAUTI, CLABSI, and HAPI on discharge disposition, controlling for participant characteristics.

RESULTS

A total of n = 29,642 patients were included, of which n = 21,469 (72%) were male, n = 16,404 (64%) were White, with a mean (SD) age of 44 (14.5) and mean (SD) Injury Severity Score of 23.2 (12.5). We created four models to test nurse-sensitive indicators, both individually and compositely, as predictors. While CAUTI and HAPI increased the odds of discharge to further care by 1.4-1.5 and 2.1 times, respectively, CLABSI was not a statistically significant predictor.

CONCLUSIONS

Both CAUTI and HAPI are statistically significant predictors of discharge to further care for patients after traumatic injury. High-quality nursing care to prevent iatrogenic complications can improve trauma patients' long-term outcomes.

Nursing students' perceptions and experiences in pressure injury risk assessment: A qualitative study

AIM

This study aims to capture the perspectives of senior undergraduate nursing students concerning pressure injury risk assessment, shedding light on their practical experiences and insights.

BACKGROUND

Pressure injuries pose a significant challenge in healthcare, demanding vigilant attention from healthcare professionals. Central to mitigating this challenge is the imperative role of risk assessment, placing nurses at the forefront of prevention strategies. Given the critical nature of this responsibility, the need for a robust and well-structured integration of risk assessment teaching within undergraduate nursing education becomes increasingly apparent.

DESIGN

This study was conducted as a descriptive qualitative study.

METHOD

This research was conducted at the Nursing Faculty of a State University in Ankara/Turkey, involving 19 senior students enrolled in the nursing program. Data was collected online using in-depth interviews with semi-structured interview questions between November and December 2022. After data collection, transcripts were generated and subjected to thematic analysis. The study was reported following the COREQ Checklist.

RESULTS

The study revealed two overarching themes: Opinions and Experiences. Within the Opinions theme, subthemes emerged, including "Features of Teaching," "Pressure Injury Definition," and "Improving Teaching Methods." The Experiences theme encompassed sub-themes such as the "Limited Relationship between Theoretical Teaching and Clinical Practice" and "Assessing the Risk of Pressure Injury in Practice."

CONCLUSION

Participants affirmed that theoretical instruction sufficiently addressed pressure injury risk assessment yet expressed concerns about the inadequacy of clinical teaching. Additionally, they underscored the need for innovative teaching methods in the theoretical instructional process.

Exploring the relationship between pressure ulcer knowledge and self-efficiency among nursing students: A multicenter study

AIM

To determine the relationship between the knowledge and self-efficiency regarding pressure ulcers of nursing students.

METHODS

This descriptive and correlational study was conducted with 775 nursing students from three different universities in various regions of Turkey. The "Pressure Ulcer Knowledge Assessment Tool-Updated Version" and "Pressure Ulcer Management Self-Efficiency Scale for Nurses" tool were used to collect data between May and September 2023. The Strengthening the Reporting of Observational Studies checklist was followed to report this study.

RESULTS

The mean knowledge score was 7.27 ± 3.09, and the mean self-efficiency on pressure ulcer management score was 35.5 ± 18.3. A statistically significant positive correlation was found between nursing students' knowledge and self-efficiency mean scores regarding pressure ulcers (p < 0.05). A significant difference was also found between the students' academic levels and gender and their knowledge and self-efficiency scores regarding pressure ulcers.

CONCLUSION

In this study, where the data covers these three institutions, students' pressure ulcer knowledge and self-efficiency scores were lower compared to all academic years. Accordingly, it was also determined that students with more nursing practice experience showed higher knowledge and self-efficacy scores than students with less nursing practice experience. Additionally, the students' self-efficacy increased along with their knowledge level. Training courses may be suggested to improve students' knowledge and self-efficiency regarding pressure ulcers.

The Effectiveness of Mobile Applications in Improving Nursing Students' Knowledge Related to Pressure Injury Prevention

The study's main goal was to compare the effects of a mobile application versus traditional methods of teaching on nursing students' acquisition of knowledge about pressure injury prevention. In addition, a secondary aim was to discover nursing students' viewpoints related to the advantages and disadvantages of using mobile applications as an educational method. A randomized controlled study design was implemented during November and December of 2023 in a nursing faculty with 60 undergraduate students in their second nursing year. A total of 30 students were assigned to the mobile application group, while the other 30 students were assigned to the traditional lecture group. The study was executed in three stages: pre-test, educational intervention, and post-test. The results of the study during the pre-test showed that there were no statistically significant differences in the mean scores of pressure injury themes between the two groups. However, the post-test scores for all PI themes were higher in the mobile application group compared to the traditional lecture group. Furthermore, five advantages of the mobile application were highlighted by students: "improvement of students' knowledge and skills", "self-confidence", "stress reduction", "enhancement of competence", and "stimulation of learning motivation". This study demonstrated the effectiveness of the mobile application method in enhancing nursing students' knowledge and prophylaxis of pressure injury. Therefore, the mobile application method is recommended as an innovative approach to teaching.

Analysis of the Current Status of Nurses' Knowledge of Pressure Injuries and Factors Influencing It in Shaanxi Province, China: A Cross-Sectional Study

Background

Pressure injuries are present in all healthcare environments and not only pose a significant health risk to individuals but also impose a heavy economic burden on society and families. Nurses, as the primary caregivers responsible for the prevention and management of pressure injuries, have knowledge that directly determines the incidence of pressure injuries.

Aim

To understand the current status of nurses' knowledge of pressure injuries in Shaanxi Province and the factors influencing it.

Design

A cross-sectional survey.

Methods

In April - May 2022, 16,599 nurses from hospitals at all levels in Shaanxi Province were selected as survey subjects by convenience sampling method. They were surveyed using the general information questionnaire and the Pieper-Zulkowski pressure injury Knowledge Questionnaire through the Questionnaire Star platform.

Results

16,599 nurses had a pressure injury knowledge score of (44.32±10.11). Wound description and pressure ulcer staging dimensions were less than 60% correct. Comparison of pressure injury knowledge scores of nursing staff with different genders, hospital levels, titles, education, whether they were specialized nurses in wound stoma when they last attended a lecture on pressure ulcers, when they last read literature or books on pressure ulcers, and whether they ever looked for information about pressure ulcers on the Internet showed that the differences were statistically significant (P < 0.05), which were the influencing factors of the knowledge scores of the nursing staff in Shaanxi Province.

Conclusion

Clinical nurses' awareness of stress-related injuries still needs to be improved, and nursing administrators can improve the quality of pressure-related injury care by increasing nursing staff's awareness through continuing education, tiered training, and other measures.

Differential effects of electronic patient record systems for wound care on hospital-acquired pressure injuries: Findings from a secondary analysis of German hospital data

INTRODUCTION

Despite the improvements made in recent decades, the OECD regards hospital-acquired pressure injuries (HAPI) as high priority areas for actions to ensure patient safety. This study was aimed at investigating the degree of utilization of two types of electronic patient record systems for wound care on lowering HAPI rates. Furthermore, the effect of user satisfaction with the systems and perceived alignment with clinical processes should be studied.

MATERIAL AND METHODS

A regression analysis of post-stratified data from German hospitals obtained from the Hospital Quality Reports (observed/expected HAPI ratio) and the IT Report Healthcare was performed. The sample comprised 319 hospitals reporting on digital wound record systems and 199 hospitals on digital nursing record systems for system utilization and the subset of hospitals using a digital system for user satisfaction and process alignment.

RESULTS

The study revealed a significant effect of hospital ownership for both types of systems and a significant interaction of ownership and system utilization for digital wound record systems: Only the for-profit hospitals benefited from a higher degree of system utilization with a lower HAPI ratio. In contrast, non-profit hospitals yielded a reversed pattern, with increasing HAPI rates matching an increased system utilization. User satisfaction (significant) and the perceived alignment of the clinical process (trend) of the digital nursing record system were related with lower HAPI ratios.

DISCUSSION

These findings point to a differential effect of system utilization on HAPI ratios depending on hospital ownership, and they demonstrate that those users who are satisfied with the system can act as catalysts for better care. The explained variance was small but comparable to other studies. Furthermore, it shows that explaining quality care is a complex undertaking. Sheer utilization has no effect while a differential perspective on the facilitators and barriers might help to explain the patient outcomes.

Pressure ulcer prevention and treatment interventions in Sub-Saharan Africa: A systematic review

BACKGROUND

The high burden of pressure ulcers (PUs) in Sub-Saharan Africa (SSA), coupled with the limited resources, underscores the need for preventive and context-specific treatment strategies.

PURPOSE

Therefore, the purpose of this systematic review was to establish and elucidate PU prevention and treatment interventions tested in SSA.

METHODS

This systematic review of the literature used, PRISMA to guide the search.

FINDINGS

The review identified nine studies on PU prevention (three) and treatment (six). Low-cost interventions assembled from locally available materials and multifaceted policies significantly prevented and treated PUs. The interventions included wound dressing agents, simple negative pressure suction devices that significantly treated PUs, and water-based bed surfaces.

DISCUSSION

There were gaps in the interventions that have been proven successful in other global settings.

CONCLUSION

In SSA, there is a need for nurses to tailor, test, and disseminate findings from evidence-based projects for PU prevention that have been successful in similar settings.

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.

Dose-response relationships between body-mass index and pressure injuries occurrence in hospitalized patients: A multi-center prospective study

BACKGROUND

Pressure injuries (PIs) are one of the leading potentially preventable hospital-acquired complications associated with prolonged hospital length, poor quality of life and financial burden. The relationship between body mass index (BMI) and PIs occurrence is controversial.

OBJECTIVE

The aim of this study was to further examine relationships between BMI and PIs occurrence in hospitalized patients.

DESIGN

A multi-center prospective study.

SETTING

39 hospitals located in northwest China from April 2021 to July 2023.

PARTICIPANTS

175,960 hospitalized patients aged over 18 years were enrolled, and 170,800 patients were included in the final analysis.

METHODS

BMI and clinical characteristics were assessed at baseline. PIs assessment were performed by trained nurses, with data recorded for the presence, the location and stage of each PI. For staging PIs, the National Pressure Ulcer Advisory Panel（NPUAP） staging system were used. The multivariate logistic regressions analysis and restricted cubic splines (RCS) models were used to explore associations between BMI and PIs, adjusting for potential confounders.

RESULTS

Of 175,960 participants, 5160 were excluded from analyses. The multivariate logistic regression model identified a positive relationship between under-weight BMI and risk of PIs occurrence (OR = 1.60, 95% CI:1.18-2.17). We also found U shaped association between BMI and PIs occurrence (non-linear P < 0.001). BMI less than 23 kg/m2 significantly increased risk of PIs, and there was a tendency to increase risk of PIs at BMI higher than 30 kg/m2. We stratified participants by sex to further investigate their association and found the risk of PIs increases substantially in women at BMI below 17 kg/m2 and in men at BMI below 23 kg/m2.

CONCLUSIONS

The present study indicated that there was an approximate U shaped relationship between BMI and PIs occurrence, and this association was potentially different between men and women.

Pressure injury education for older adults and carers living in community settings: A scoping review

Older adults are at increased risk of pressure injuries (PIs) due to age-related changes. Traditionally, PI knowledge and education have been delivered in hospitals and residential aged care facilities, however, there remains a critical gap in understanding how PI knowledge on prevention and management is shared with older adults and their carers living in the community. We aimed to describe the nature and characteristics of structured and unstructured PI education programs available to community-dwelling older adults and their carers. As coping review was undertaken. We searched five databases: CINAHL, Medline, Scopus, Cochrane Library and ProQuest from 2009 to August 2023. The review was guided by Arksey and O'Malley's six-step framework and adhered to the PRISMA-ScR guidelines. It included primary peer-reviewed papers published in English, which focus on PI education for older adults and/or their carers living in community settings. Data extraction was organised in a table, and findings presented as a narrative summary. One-hundred and thirty-six papers were screened and four included in the review. Results indicate that consideration was placed on literacy levels and cognitive status of older adults and their carers when designing PI education materials. Educational materials such as leaflets/brochures, in-person training sessions or a combination of both were used. However, duration of these interventions varied, lasting for 1-4 weeks while others were completed over 12 months. Some improvements in PI knowledge such as how to treat PI, dietary requirements and importance of mobility were noted. However, information retention and its translation into effective long-term behaviour change remained unclear. In conclusion, adopting a multifaceted educational approach increases the effectiveness of PI knowledge translation. Continuous education, support and reinforcement on PIs over time are necessary when interacting with older adults and caregivers to ensure long-term management and prevention success. Conversations on PIs should start at the primary care levels when older adults and carers are visiting their GP clinics and accessing support services for other healthcare needs. Understanding older adults' and carers' literacy levels, cognitive status and cultural background can assist clinicians in designing and delivering fit-for-purpose PI educational interventions that are accessible, relatable and effective in promoting knowledge transfer and behaviour change. Carers are vital conduits in the care continuum. These factors will lead to a more informed, collaborative and person-centred approaches to PI management and prevention.

Comparison of the predictive validity of the Braden and Waterlow scales in intensive care unit patients: A multicentre study

BACKGROUND

The first step in preventing pressure injuries (PIs), which represent a significant burden on intensive care unit (ICU) patients and the health care system, is to assess the risk for developing PIs. A valid risk assessment scale is essential to evaluate the risk and avoid PIs.

OBJECTIVES

To compare the predictive validity of the Braden scale and Waterlow scale in ICUs.

DESIGN

A multicentre, prospective and cross-sectional study.

METHODS

We conducted this study among 6416 patients admitted to ICUs in Gansu province of China from April 2021 to October 2022. The incidence and characteristics of PIs were collected. The risk assessment of PIs was determined using the Braden and Waterlow scale. The sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve of the two scales were compared.

RESULTS

Out of 5903 patients, 72 (1.2%) developed PIs. The sensitivity, specificity, positive and negative predictive, and the area under the curve of the Braden scale were 77.8%, 50.9%, 0.014 and 0.996, and 0.689, respectively. These values for the Waterlow scale were 54.2%, 71.1%, 0.017, 0.994 and 0.651.

CONCLUSIONS

Both scales could be used for risk assessment of PIs in ICU patients. However, the accuracy of visual inspection for assessment of skin colour, nursing preventive measures for patients and scales inter-rater inconsistency may limited the predictive validity statistics.

RELEVANCE TO CLINICAL PRACTICE

Both scales could be used for PIs risk assessment. The low specificity of the Braden scale and low sensitivity of the Waterlow scale remind medical staff to use them in combination with clinical judgement and other objective indicators.

PATIENT OR PUBLIC CONTRIBUTION

This study was designed to enhance the management of PIs. Patients and the general public were not involved in the study design, analysis, and interpretation of the data or manuscript preparation.

Can a prolonged healing pressure injury be benefited by using an AI mattress? A case study

BACKGROUND

Pressure injuries are a common and serious issue for bedridden residents in long-term-care facilities. Areas of bony prominences, such as the scapula, sacrum, and heels, are more likely to develop pressure injuries. The management of pressure injury wounds include dressing changes, repositioning, away from moisture, decreasing the occurrence of friction and shear, and more. Some supportive surfaces are also used for pressure injury cases such as gel pads, alternating pressure air mattresses, and air-fluidized beds. The aim of this case study was to determine whether the use of an artificial intelligent mattress can improve a nursing home resident with prolonged pressure injury.

CASE PRESENTATION

A retrospective study design was conducted for this case study. A 79-year-old male developed a pressure injury in the sacrum. His pressure injury was initially at stage 4, with a score of 12 by the Braden scale. The PUSH score was 16. During 5.5 months of routine care plus the use of the traditional alternative air mattress, in the nursing home, the wound stayed in stage 3 but the PUSH score increased up to 11. An artificial intelligence mattress utilizing 3D InterSoft was used to detect the bony prominences and redistribute the external pressure of the skin. It implements a color guided schematic of 26 colors to indicate the amount of pressure of the skin.

RESULTS

The wound size was decreased and all eczema on the resident's back diminished. The PUSH score was down to 6, as the artificial intelligent mattress was added into the routine care. The staff also reported that the resident's quality of sleep improved and moaning decreased. The hemiplegic side is at greater risk of developing pressure injury.

CONCLUSIONS

This novice device appeared to accelerate wound healing in this case. In the future, more cases should be tested, and different care models or mattress can be explored.

Artificial intelligence in wound care: diagnosis, assessment and treatment of hard-to-heal wounds: a narrative review

OBJECTIVE

The effective assessment of wounds, both acute and hard-to-heal, is an important component in the delivery by wound care practitioners of efficacious wound care for patients. Improved wound diagnosis, optimising wound treatment regimens, and enhanced prevention of wounds aid in providing patients with a better quality of life (QoL). There is significant potential for the use of artificial intelligence (AI) in health-related areas such as wound care. However, AI-based systems remain to be developed to a point where they can be used clinically to deliver high-quality wound care. We have carried out a narrative review of the development and use of AI in the diagnosis, assessment and treatment of hard-to-heal wounds. We retrieved 145 articles from several online databases and other online resources, and 81 of them were included in this narrative review. Our review shows that AI application in wound care offers benefits in the assessment/diagnosis, monitoring and treatment of acute and hard-to-heal wounds. As well as offering patients the potential of improved QoL, AI may also enable better use of healthcare resources.

The prevalence and risk factors of pressure ulcers among residents of long-term care institutions: a case study of Kazakhstan

Limited information is available regarding the prevalence of pressure ulcers (PUs) in residential homes in Central Asia. Therefore, the aim of this study was to identify the prevalence rates and risk factors associated with PUs among residents of long-term care medical institutions in the Republic of Kazakhstan. This cross-sectional study was conducted in four long-term care institutions in Kazakhstan. The study sample consisted of 640 patients who were assessed for the presence of PUs and associated risk factors. The evaluation was performed using the International Prevalence Measurement of Care Quality (Landelijke Prevalentiemeting Zorgkwaliteit, LPZ), the Braden scale, and the Care Dependency Score (CDS). The overall prevalence of PUs, classified as categories I-IV, was found to be 37%. When excluding category I PUs, the prevalence decreased to 35.6%. The odds ratios (ORs) for presenting with PUs were as follows: history of stroke (OR 5.22), diseases of the digestive system (OR 10.01), presence of spinal cord lesions/paraplegia (OR 20.50), recent reported confusion within the last 7 days (OR 184.00), and limited extent dependency according to the CDS (OR 4.44; 95%CI 1.31-16.1). It is imperative to establish specialized training programs aimed at equipping medical personnel, relatives, and patients themselves with the necessary skills to provide optimal care for individuals affected by PUs.

Beliefs and practices of the nursing team related to pressure injury preventive measures: A analysis of social representations

AIMS AND OBJECTIVES

To analyse the process of elaborating social representations about pressure injury preventive measures by the nursing team (nurses and nurse technicians) and how this process relates to preventive practices for hospitalized patients.

DESIGN

Qualitative study, with the application of the theory of social representations in its procedural methodological approach.

METHODS

The study was carried out in an inpatient clinic of a public hospital in the state of Rondônia, Brazil. Totally, 28 nursing professionals in the medical clinic sectors who had worked directly with patient care for more than 6 months participated. The data were collected between July and September 2021 via in-depth interviews with the application of a semi-structured instrument. Analysis was carried out with the help of ALCESTE software, which performed a lexicographic analysis, and also via thematic analysis. The COREQ guided the presentation of the research report.

RESULTS

The social representations were developed based on the professionals' symbolic beliefs about the visibility/invisibility of the results of applying preventive care. These symbolic constructions mobilized positive and negative feelings among the nursing team, which guided the classification of prevention practices as being of greater or lesser priority among other care activities. There were favourable attitudes among professionals, which included applying prevention measures in their daily routines, and unfavourable attitudes of non-adherence to the institution's protocol for preventing pressure injuries.

CONCLUSIONS

The nursing team's perception of pressure injury prevention is influenced by symbolic, affective, values, and social dimensions. Non-adherence behaviours are attributed to the belief in the invisibility of prevention outcomes, resulting in a reluctance to implement preventive measures.

RELEVANCE TO CLINICAL PRACTICE

Understanding the subjective logic that explains the thinking and actions of the nursing team suggests the need to incorporate discussions on beliefs, values, sentiments, and attitudes of nursing professionals into educational programs on pressure injury prevention.

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.

Barriers and facilitators to pressure ulcer prevention behaviours by older people living in their own homes and their lay carers: a qualitative study

OBJECTIVE

To identify barriers and facilitators to pressure ulcer prevention behaviours in community-dwelling older people and their lay carers.

DESIGN

Theoretically informed qualitative interviews with two-phase, deductive then inductive, thematic analysis.

SETTING

The study was conducted in one geographical region in the UK, spanning several community National Health Service Trusts.

PARTICIPANTS

Community-dwelling older patients at risk of pressure ulcer development (n=10) and their lay carers (n=10).

RESULTS

Six themes and subthemes were identified: (1) knowledge and beliefs about consequences (nature, source, timing and taboo); (2) social and professional role and influences (who does what, conflicting advice and disagreements); (3) motivation and priorities (competing self-care needs and carer physical ability); (4) memory; (5) emotion (carer exhaustion and isolation, carergiver role conflict and patient feelings) and (6) environment (human resource shortage and equipment).

CONCLUSIONS

There is minimal research in pressure ulcer prevention in community-dwelling older people. This study has robustly applied the theoretical domains framework to understanding barriers and facilitators to pressure ulcer prevention behaviours. Our findings will support co-design of strategies to promote preventative behaviours and are likely to be transferable to comparable healthcare systems nationally and internationally.

Incidence of hospital-acquired pressure injuries and predictors of severity in a paediatric hospital

BACKGROUND

Hospital-acquired pressure injuries (HAPIs) pose significant challenges in healthcare and cause increased patient suffering, longer hospital stays, and higher healthcare costs. Paediatric patients face unique risks, but evidence remains scarce. This study aimed to identify and describe HAPI admission incidence and severity predictors in a large Australian children's hospital.

METHODS

This retrospective cohort study investigated all paediatric patients between January 2020 and December 2021 using a census approach. Demographic and clinical data including HAPI-related data were accessed from the incident monitoring and hospital administration databases. The incidence rate (per 1000 patient admissions) was calculated based on all admissions. Predictors of HAPI severity were identified using multivariable multinomial logistic regression. The study adhered to the STROBE guidelines for retrospective cohort studies.

RESULTS

The HAPI incidence rate was 6.96 per 1000 patient admissions. Of the age groups, neonates had the highest HAPI incidence (15.5 per 1000 admissions). Critically ill children had the highest rate for admission location (12.8 per 1000 patient admissions). Most reported cases were stage I (64.2%). Age was associated with injury severity, with older paediatric patients more likely to develop higher-stage HAPIs. Additionally, Aboriginal and/or Torres Strait Islander patients had a higher HAPI severity risk.

CONCLUSION

HAPI injuries in paediatric patients are unacceptably high. Prevention should be prioritized, and the quality of care improved in Australia and beyond. Further research is needed to develop targeted prevention strategies for these vulnerable populations.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

This research emphasizes the need for standardized reporting, culturally sensitive care and tailored prevention strategies.

IMPACT

The research has the potential to influence healthcare policies and practices, ultimately enhancing the quality of patient care.

REPORTING METHOD

STROBE guidelines.

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.

Antibacterial, ROS scavenging and angiogenesis promotingϵ-Polylysine/gelatin based hydrogel containing CTLP to regulate macrophages for pressure ulcer healing

Pressure ulcers (PUs) have emerged as a substantial burden on individuals and society. The introduction of innovative dressings that facilitate the healing of pressure ulcer wounds represents a cost-effective alternative for treatment. In this study, the emphasis is on the preparation of Carthamus tinctorius L. polysaccharide (CTLP) as hydrogel microspheres (MPs), which are then encapsulated within a hydrogel matrix crosslinked with phenylboronic acid gelatin (Gelatin-PBA) andϵ-polylysine-grafted catechol (ϵ-PL-Cat) to enable sustained release for promoting pressure ulcer healing. The presented Gelatin-PBA/ϵ-PL-Cat (GPL)/CTLP-MPs hydrogel demonstrated outstanding self-healing properties. In addition,in vitroexperiments revealed that the hydrogel exhibited remarkable antibacterial activity, excellent biocompatibility. And it showed the capacity to promote vascular formation, effectively scavenge reactive oxygen species, and facilitate macrophage polarization from the M1 to M2 phenotype.In vivowound healing of mice PUs indicated that the prepared GPL/CTLP-MPs hydrogel effectively accelerated the formation of granulation tissue and facilitated the healing of the wounds. In summary,in vivoandin vitroexperiments consistently highlight the therapeutic potential of GPL/CTLP-MPs hydrogel in facilitating the healing process of PUs.

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.

Enhancing Pressure Injury Surveillance Using Natural Language Processing

OBJECTIVE

This study assessed the feasibility of nursing handoff notes to identify underreported hospital-acquired pressure injury (HAPI) events.

METHODS

We have established a natural language processing-assisted manual review process and workflow for data extraction from a corpus of nursing notes across all medical inpatient and intensive care units in a tertiary care pediatric center. This system is trained by 2 domain experts. Our workflow started with keywords around HAPI and treatments, then regular expressions, distributive semantics, and finally a document classifier. We generated 3 models: a tri-gram classifier, binary logistic regression model using the regular expressions as predictors, and a random forest model using both models together. Our final output presented to the event screener was generated using a random forest model validated using derivation and validation sets.

RESULTS

Our initial corpus involved 70,981 notes during a 1-year period from 5484 unique admissions for 4220 patients. Our interrater human reviewer agreement on identifying HAPI was high ( κ = 0.67; 95% confidence interval [CI], 0.58-0.75). Our random forest model had 95% sensitivity (95% CI, 90.6%-99.3%), 71.2% specificity (95% CI, 65.1%-77.2%), and 78.7% accuracy (95% CI, 74.1%-83.2%). A total of 264 notes from 148 unique admissions (2.7% of all admissions) were identified describing likely HAPI. Sixty-one described new injuries, and 64 describe known yet possibly evolving injuries. Relative to the total patient population during our study period, HAPI incidence was 11.9 per 1000 discharges, and incidence rate was 1.2 per 1000 bed-days.

CONCLUSIONS

Natural language processing-based surveillance is proven to be feasible and high yield using nursing handoff notes.

Validity and Reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test for Use in Turkey

OBJECTIVE

To assess the validity and reliability of the Pieper-Zulkowski Pressure Ulcer Knowledge Test (PZ-PUKT) for use in Turkey.

METHODS

This methodological study was carried out at a state hospital from June to November 2022. The authors used the PZ-PUKT and nurse identification form for data collection. They assessed the validity and reliability of the PZ-PUKT for Turkish society by evaluating language validity, content validity index, exploratory factor analysis, confirmatory factor analysis, Cronbach α, Spearman-Brown Split-Half analysis, item-scale correlations, and test-retest correlations.

RESULTS

Item-level content validity indices ranged from .778 to 1.000 and the scale-level content validity index was .960. Factor loadings of the Turkish version of the PZ-PUKT ranged between .297 and .671. Cronbach α coefficients for the scale subsections were .838 for wounds, .851 for prevention, and .844 for staging; the Cronbach α coefficient was .936 for the total scale score.

CONCLUSIONS

The PZ-PUKT is valid and reliable for use with nurses in Turkey. The authors recommend using the Turkish version of the tool in education and research to assess nurses' pressure injury knowledge.

Effects of predictive nursing interventions on pressure ulcer in older bedridden patients: A meta-analysis

To evaluate the effect of predictive nursing interventions on pressure ulcers in elderly bedridden patients by meta-analysis. Applied computer searches of PubMed, Embase, Google Scholar, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases for randomised controlled trials (RCTs) on the effect of predictive nursing in preventing pressure ulcers in elderly bedridden patients from the database inception to November 2023. Two researchers independently screened the literature, extracted data and performed quality assessment based on inclusion and exclusion criteria. Stata 17.0 software was utilised for data analysis. Eighteen RCTs involving 6504 patients were finally included. The analysis revealed the implementation of predictive nursing interventions had a significant advantage in reducing the incidence of pressure ulcers in elderly bedridden patients compared with conventional nursing (odds ratio [OR] = 0.20, 95% confidence interval [CI]: 0.15-0.28, p < 0.001), while the patients' satisfaction with nursing care was higher (OR = 3.70, 95% CI: 2.99-4.57, p < 0.001). This study shows that the implementation of a predictive nursing interventions for elderly bedridden patients can effectively reduce the occurrence of pressure ulcers and significantly improve patients' satisfaction with nursing care, which is worthy of clinical promotion and application.

The correlation between sub-epidermal moisture measurement and other early indicators of pressure ulcer development-A prospective cohort observational study. Part 1. The correlation between sub-epidermal moisture measurement and ultrasound

The correlation between sub-epidermal moisture (SEM) and other early indicators of pressure ulcer (PU) development is yet to be determined. This three-part series aims to bridge this knowledge gap, through investigating SEM and its correlation with evidence-based technologies and assessments. This article focuses on the correlation between SEM and ultrasound. A prospective cohort observational study was undertaken between February and November 2021. Patients undergoing three surgery types were consecutively enrolled to the study following informed consent. Assessments were performed prior to and following surgery for 3 days at the sacrum, both heels and a control site, using a SEM scanner and high-frequency ultrasound scanner (5-15 MHz). Spearman's rank (rs ) explored the correlation between SEM and ultrasound. A total of 60 participants were included; 50% were male with a mean age of 58 years (±13.46). A statistically significant low to moderately positive correlation was observed between SEM and ultrasound across all anatomical sites (rs range = 0.39-0.54, p < 0.05). The only exception was a correlation between SEM and ultrasound on day 0 at the right heel (rs  = 0.23, p = 0.09). These results indicate that SEM and ultrasound agreed in the presence of injury; however, SEM was able to identify abnormalities before ultrasound.

Key stakeholders' perspectives: A gap analysis of hospital-acquired pressure injuries

INTRODUCTION

Hospital-acquired pressure injuries (HAPIs) are a global high-stakes patient safety issue. Key stakeholder perspectives regarding their role and experiences with pressure injuries is critical as part of the solution to minimizing HAPI occurrence and attain sustainability.

DESIGN

A qualitative, descriptive approach provided multiple perspectives of key stakeholders to support the complexity of HAPI care. The qualitative data are a part of a mixed method convergent research study examining pressure injury prevention and management practices.

METHODS

Nursing system theory, mixed method convergent design, and participatory action research methodologies were chosen to address both the gap analysis development and results, achieve collaborative comprehensiveness, and enable key stakeholder involvement throughout this HAPI prevention and management initiative. Participants were recruited and enrolled from a large Level I trauma hospital and the key stakeholders. Demographic information were collected prior to the individual interview. Focused interviews were conducted virtually using zoom technology. Qualitative data were analyzed using NVivo software and thematic analysis was confirmed across the co-investigators for congruence and applicability to the research questions.

RESULTS

Qualitative interviews with 26 key stakeholders provided data to support and integrate a link with gap analysis results on the complex health issue of HAPIs. Specific barrier and recommendation themes identified interventions that could be prioritized. The 52 barrier and 52 recommendation themes/sub-theme(s) respectively were organized by Donabedian (structure, process, and outcome) with structure elements the majority. The top three structure barrier themes involved equipment and standards for use, staff prevention education, and specialized health professionals. The top three structure recommendation themes involved specialized health professionals, equipment and standards for use, and an educational plan for those at risk or with HAPIs.

CONCLUSION

The article provides findings from the qualitative portion of a mixed method study related to HAPIs. The qualitative findings associated with the gap analysis quantitative results, achieved the goal of the participatory action research key stakeholders' input into HAPI care and can be replicated internationally.

CLINICAL RELEVANCE

The benefit of key stakeholder's involvement in solving a clinical problem is sustainability. A quantitative approach and integrating qualitative stakeholders' perspectives provide an in-depth solution that will advance nursing capacity toward health care delivery and HAPI nursing science and policy development on a global level.

Effects of cluster nursing interventions on the prevention of pressure ulcers in intensive care units patients: A meta-analysis

A meta-analysis was conducted to comprehensively evaluate the impact of cluster nursing interventions on the prevention of pressure ulcers (PUs) in intensive care unit (ICU) patients. Computer searches were performed in databases including Embase, Google Scholar, Cochrane Library, PubMed, Wanfang and China National Knowledge Infrastructure for randomized controlled trials (RCTs) implementing cluster nursing interventions for PUs prevention in ICU patients, with the search period covering the database inception to November 2023. Two researchers independently screened the literature, extracted data and conducted quality assessments. Stata 17.0 software was employed for data analysis. Overall, 17 RCTs involving 1463 ICU patients were included. The analysis showed that compared with conventional nursing, cluster nursing interventions significantly reduced the incidence of PUs (odds ratio: 0.24, 95% confidence intervals [CI]: 0.17-0.34, p < 0.001) and also significantly improved the levels of anxiety (standardized mean difference [SMD]: -1.39, 95% CI: -1.57 to 1.22, p < 0.001) and depression (SMD: -1.64, 95% CI: -2.02 to 1.26, p < 0.001) in ICU patients. This study indicates that the application of cluster nursing interventions in ICU patients can effectively reduce the incidence of PUs, as well as improve patients' anxiety and depression levels, thereby enhancing their quality of life, which is worth clinical promotion and application.

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.

Nutritional interventions for preventing and treating pressure ulcers

BACKGROUND

Pressure ulcers are localized injuries to the skin or the underlying tissue, or both, and are common in older and immobile people, people with diabetes, vascular disease, or malnutrition, as well as those who require intensive or palliative care. People with pressure ulcers often suffer from severe pain and exhibit social avoidance behaviours. The prevention and treatment of pressure ulcers involves strategies to optimize hydration, circulation, and nutrition. Adequate nutrient intake can reduce the risk factor of malnutrition and promote wound healing in existing pressure ulcers. However, it is unclear which nutrients help prevent and treat pressure ulcers. This is an update of an earlier Cochrane Review.

OBJECTIVES

To evaluate the benefits and harms of nutritional interventions (special diets, supplements) for preventing and treating pressure ulcers in people with or without existing pressure ulcers compared to standard diet or other nutritional interventions.

SEARCH METHODS

We used extensive Cochrane search methods. The latest search was in May 2022.

SELECTION CRITERIA

We included randomized controlled trials (RCTs) in people with or without existing pressure ulcers, that compared nutritional interventions aimed at preventing or treating pressure ulcers with standard diet or other types of nutritional interventions.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcome for prevention studies was the proportion of participants who developed new (incident) pressure ulcers. For treatment studies, our primary outcomes were time to complete pressure ulcer healing, number of people with healed pressure ulcers, size and depth of pressure ulcers, and rate of pressure ulcer healing. Secondary outcomes were side effects, costs, health-related quality of life and acceptability. We used GRADE to assess certainty of evidence for each outcome.

MAIN RESULTS

We included 33 RCTs with 7920 participants. Data for meta-analysis were available from 6993 participants. Pressure ulcer prevention Eleven studies (with 12 arms) compared six types of nutritional interventions for the prevention of pressure ulcers. Compared to standard diet, energy, protein and micronutrient supplements may result in little to no difference in the proportion of participants developing a pressure ulcer (energy, protein and micronutrient supplements 248 per 1000, standard diet 269 per 1000; RR 0.92, 95% CI 0.71 to 1.19; 3 studies, 1634 participants; low-certainty evidence). Compared to standard diet, protein supplements may result in little to no difference in pressure ulcer incidence (protein 21 per 1000, standard diet 28 per 1000; RR 0.75, 95% CI 0.49 to 1.14; 4 studies, 4264 participants; low-certainty evidence). The evidence is very uncertain about the gastrointestinal side effects of these supplements (protein 109 per 1000, standard diet 155 per 1000; RR 0.70, 95% CI 0.06 to 7.96; 2 studies, 140 participants, very low-certainty evidence). The evidence is very uncertain about the effects of protein, arginine, zinc and antioxidants; L-carnitine, L-leucine, calcium, magnesium and vitamin D; EPA, GLA and antioxidants; disease-specific supplements on pressure ulcer incidence when compared to standard diet (1 study each; very low-certainty evidence for all comparisons). Pressure ulcer treatment Twenty-four studies (with 27 arms) compared 10 types of nutritional interventions or supplements for treatment of pressure ulcers. Compared to standard diet, energy, protein and micronutrient supplements may slightly increase the number of healed pressure ulcers (energy, protein and micronutrients 366 per 1000, standard diet 253 per 1000; RR 1.45, 95% CI 1.14 to 1.85; 3 studies, 577 participants, low-certainty evidence). The evidence is very uncertain about the effect of these supplements on gastrointestinal side effects. Compared to standard diet, the evidence is very uncertain about the effect of protein, arginine, zinc and antioxidant supplements on pressure ulcer healing (pressure ulcer area: mean difference (MD) 2 cm² smaller, 95% CI 4.54 smaller to 0.53 larger; 2 studies, 71 participants, very low-certainty evidence). The evidence on side effects of these supplements is very uncertain. Compared to standard diet, supplements with arginine and micronutrients may not increase the number of healed pressure ulcers, but the evidence suggests a slight reduction in pressure ulcer area (MD 15.8% lower, 95% CI 25.11 lower to 6.48 lower; 2 studies, 231 participants, low-certainty evidence). The evidence is very uncertain about changes in pressure ulcer scores, acceptability, and side effects of these supplements. Compared to placebo, collagen supplements probably improve the mean change in pressure ulcer area (MD 1.81 cm² smaller, 95% CI 3.36 smaller to 0.26 smaller; 1 study, 74 participants, moderate-certainty evidence). The evidence is very uncertain about the effect of these supplements on side effects. The evidence is very uncertain about the effects of vitamin C, different doses of arginine; EPA, GLA (special dietary fatty acids) and antioxidants; protein; a specialized amino acid mixture; ornithine alpha-ketoglutarate and zinc supplements on pressure ulcer healing (1 or 2 studies each; very low-certainty evidence).

AUTHORS' CONCLUSIONS

The benefits of nutritional interventions with various compositions for pressure ulcer prevention and treatment are uncertain. There may be little or no difference compared to standard nutrition or placebo. Nutritional supplements may not increase gastrointestinal side effects, but the evidence is very uncertain. Larger studies with similar nutrient compositions would reduce these uncertainties. No study investigated the effects of special diets (e.g. protein-enriched diet, vegetarian diet) on pressure ulcer incidence and healing.

Prevalence of pressure injury on the medical wards of public general hospitals in Kuwait: a national cross-sectional study

BACKGROUND

Pressure injury is a severe problem that can significantly impact a patient's health, quality of life, and healthcare expenses. The prevalence of pressure injuries is a widely used clinical indicator of patient safety and quality of care. This study aims to address the research gap that exists on this topic in Kuwait by investigating the prevalence of pressure injuries and preventive measures on the medical wards of the country's public general hospitals.

METHODS

A cross-sectional research design was adopted to measure the point prevalence of pressure injuries on 54 medical wards in the public general hospitals. Data, including variables pertaining to hospitals, patients, pressure injuries and preventive practices, were collected using an online form. The data were processed and analysed using Microsoft Excel and SPSS 23 (α level = 0.05). Analysis provided an overview of patient, pressure injury characteristics and preventive measures, and the relationships between the patient and pressure injury characteristics and the prevalence of pressure injuries. A model for predicting the determinants of pressure injury prevalence was constructed from a linear regression analysis.

RESULTS

The mean national prevalence of pressure injury was 17.6% (95% CI: 11.3-23.8). Purely community-acquired pressure injuries represent the majority of pressure injuries nationally (58.1%). Regarding preventive measures, "pressure injury assessment on admission" has been provided to 65.5% of patients. Correlation analysis revealed that the only statistically significant correlation with the prevalence of hospital-acquired pressure injury was "pressure injury assessment on admission", which was strongly negative (ρ = -0.857). Therefore, this was the only variable included in the regression analysis as a predictor of pressure injury prevalence (Beta = 0.839). The results showed many statistically significant differences between hospitals with respect to the variables studied.

CONCLUSIONS

The national pressure injury prevalence is high compared to the global rate. The higher percentage of purely community-acquired pressure injuries requires particular attention. Many risk factors for the development of pressure injuries are public health concerns, and effective mitigating strategies are needed. Further research is required to assess the knowledge, attitude, and behaviour of nurses with respect to pressure injuries, and to evaluate preventive and management practices.

Investigation of factors associated with pressure ulcer in patients receiving home care services via path analysis

BACKGROUND

Recent trends indicate a rise in the number of elderly and bedridden patients enrolled in home care programs, leading to an increased occurrence of complications such as pressure ulcers within the home health care setting.

OBJECTIVE

The primary objective of this research was to ascertain the prevalence of pressure ulcers and identify the associated factors in adults who were recipients of home health care services.

METHOD

This study, adopting a cross-sectional design, encompassed a sample of 566 patients who sought services from the Home Health Care Unit in a specific province in Turkey. The timeframe for data collection spanned from August to November 2022, during which two primary instruments were employed: the "Demographic Characteristics Form" and two specific scales - the "Braden Pressure Ulcer Risk Assessment Scale" and the "ITAKI Falls Risk Scale."

FINDINGS

In this study, the average age of patients receiving home health care services was identified as 75.9 years, with a standard deviation of 15.1 years. Furthermore, 73.7 % of these patients were classified as being at risk for developing pressure ulcers. The study identified a direct correlation between the risk of BRADEN pressure ulcers and the escalation in scores across several parameters. These parameters included "Addiction Status," delineated as a spectrum from addicted to non-addicted, the "Number of Medical Diagnoses," quantified on a scale, the "State of Consciousness," categorized from clear to confused, and the scores derived from the "ITAKI" scale.

CONCLUSION

The findings of this study highlight the significance of pressure ulcers as a critical health issue among patients receiving home care services. It underscores the necessity for home care nurses to be acutely aware of the risk factors associated with pressure ulcers among high-risk patients.

The clinical applicability of sensor technology with body position detection to combat pressure ulcers in bedridden patients

INTRODUCTION

Pressure Ulcers (PUs) are a major healthcare issue leading to prolonged hospital stays and decreased quality of life. Monitoring body position changes using sensors could reduce workload, improve turn compliance and decrease PU incidence.

METHOD

This systematic review assessed the clinical applicability of different sensor types capable of in-bed body position detection.

RESULTS

We included 39 articles. Inertial sensors were most commonly used (n = 14). This sensor type has high accuracy and is equipped with a 2-4 hour turn-interval warning system increasing turn compliance. The second-largest group were piezoresistive (pressure) sensors (n = 12), followed by load sensors (n = 4), piezoelectric sensors (n = 3), radio wave-based sensors (n = 3) and capacitive sensors (n = 3). All sensor types except inertial sensors showed a large variety in the type and number of detected body positions. However, clinically relevant position changes such as trunk rotation and head of bed elevation were not detected or tested.

CONCLUSION

Inertial sensors are the benchmark sensor type regarding accuracy and clinical applicability but these sensors have direct patient contact and (re)applying the sensors requires the effort of a nurse. Other sensor types without these disadvantages should be further investigated and developed. We propose the Pressure Ulcer Position System (PUPS) guideline to facilitate this.

Inter-device agreement of sacral subepidermal oedema measurement in healthy adults during prolonged 60° head of bed elevation

AIM

To investigate the level of agreement between the SEM 200 and Provisio® subepidermal moisture sacral delta measurements, which may indicate increased pressure injury risk, in healthy adults during 120 min of prolonged 60° head of bed elevation. This position, which requires the elevation of the patient's upper body at a 60° angle above the horizontal plane for an extended period, is used by clinicians to prevent or manage a patient's medical or surgical conditions.

DESIGN

This prospective exploratory study recruited 20 healthy adults during October 2021 and collected sacral subepidermal moisture delta measurements using the SEM 200 and Provisio® devices.

METHODS

Delta measurements were taken at 20-min intervals over 120 min resulting in seven data collection timepoints. Descriptive statistics and a Bland Altman plot analysis were conducted.

RESULTS

A total of 280 sacral subepidermal moisture delta measurements were gathered or 140 per device. There were good levels of agreement between the two devices at baseline (T0) [mean 0.025; SD 0.137] and following 60- (T3) [mean 0.025; SD 0.111], 80- (T4) [mean -0.01; SD 0.177] and 100 min (T5) [mean 0.01; SD 0.129] of prolonged 60° head of bed elevation. Head of bed elevations can increase a patient's risk of sacral pressure injuries. In some countries, nurses have access to the SEM 200 and/or the Provisio® device, so our findings may increase nurses' confidence in the interchangeability of the device measurements, although further research is needed to confirm this. The SEM 200 and Provisio® subepidermal moisture scanners show promise in gathering similar objective pressure injury risk data which could prompt clinicians to implement prevention strategies.

IMPACT

Current pressure injury risk assessment is largely subjective in nature. This quantitative study on healthy human sacral tissue found a good level of agreement in the SEM 200 and Provisio® subepidermal moisture scanners, which may increase nurses' confidence in the interchangeability of the devices in clinical practice.

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

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

Risk factors predicting hospital-acquired pressure injury in adult patients: An overview of reviews

BACKGROUND

Hospital-acquired pressure injuries remain a significant patient safety threat. Current well-known pressure injury risk assessment tools have many limitations and therefore do not accurately predict the risk of pressure injury development over diverse populations. A contemporary understanding of the risk factors predicting pressure injury in adult hospitalised patients will inform pressure injury prevention and future researchers considering risk assessment tool development may benefit from our summary and synthesis of risk factors.

OBJECTIVE

To summarise and synthesise systematic reviews that identify risk factors for hospital-acquired pressure injury development in adult patients.

DESIGN

An overview of systematic reviews.

METHODS

Cochrane and the Joanna Briggs Institute methodologies guided this overview. The Cochrane library, CINAHL, MEDLINE, and Embase databases were searched for relevant articles published in English from January 2008 to September 2022. Two researchers independently screened articles against the predefined inclusion and exclusion criteria, extracted data and assessed the quality of the included reviews using "a measurement tool to assess systematic reviews" (AMSTAR version 2). Data were categorised using an inductive approach and synthesised according to the recent pressure injury conceptual frameworks.

RESULTS

From 11 eligible reviews, 37 risk factors were categorised inductively into 14 groups of risk factors. From these, six groups were classified into two domains: four to mechanical boundary conditions and two to susceptibility and tolerance of the individual. The remaining eight groups were evident across both domains. Four main risk factors, including diabetes, length of surgery or intensive care unit stay, vasopressor use, and low haemoglobin level were synthesised. The overall quality of the included reviews was low in five studies (45 %) and critically low in six studies (55 %).

CONCLUSIONS

Our findings highlighted the limitations in the methodological quality of the included reviews that may have influenced our results regarding risk factors. Current risk assessment tools and conceptual frameworks do not fully explain the complex and changing interactions amongst risk factors. This may warrant the need for more high-quality research, such as cohort studies, focussing on predicting hospital-acquired pressure injury in adult patients, to reconsider these risk factors we synthesised.

REGISTRATION

This overview was registered with the PROSPERO (CRD42022362218) on 27 September 2022.

Nomogram model on estimating the risk of pressure injuries for hospitalized patients in the intensive care unit

OBJECTIVES

This study aimed to build and validate a nomogram model to estimate the risk of pressure injuries in intensive care unit patients.

DESIGN

Multicenter prospective cohort study.

SETTING

33 tertiary hospitals in the Gansu Province, China.

MEASUREMENTS AND MAIN RESULTS

This study included 6420 patients between April 2021 to October 2022 from an information platform of pressure injury risk management called the "Long Hu Hui." Univariate and multivariate logistic regression analyses identified pressure injury risk factors to be included in the nomogram. The resulting nomogram was tested for calibration discrimination, and clinical usefulness. Of the included patients, 77 developed pressure injuries, representing an incidence rate of 1.2 %. Analysis of binary logistic regression revealed that the estimation nomogram included weight loss greater than 5 kg in the last three months, pneumotomy cannula, thoracic catheter, isoproterenol, norepinephrine, abnormal skin color, ruptured erythema, stroke, increased body temperature and nonspecific patients (specific patients include paralysis, unconsciousness, dementia, forced body position). The area under the receiver operating characteristic curve for the training cohort was 0.806 (95 % CI 0.755-0.857), and the AUC of the text cohort was 0.737 (95 % CI 0.574-0.901). The model has excellent calibration in both the training cohort (H-L test: χ2 = 6.34, P = 0.61) and the text cohort (H-L test: χ2 = 4.50, P = 0.81). Furthermore, the decision curve analysis revealed the preferred net benefit and the threshold probability in the estimation nomogram.

CONCLUSIONS

The nomogram model accurately estimated the risk of pressure injuries among intensive care patients, it should be used to inform risk assessment and facilitate early intervention strategies in future practice.

IMPLICATIONS FOR CLINICAL PRACTICE

The nomogram allows intensive care providers to dynamically assess the patient's risk of pressure injuries and to implement more targeted interventions accordingly.

The practice and facilitators of, and barriers to, implementing individualized repositioning frequency: A national cross-sectional survey of critical care nurses

AIMS

To understand the clinical status of implementing individualized repositioning frequency-and its barriers and facilitators-among critical care nurses in China, in view of developing targeted intervention strategies and improving guideline implementation.

DESIGN

A cross-sectional survey.

METHODS

A self-report questionnaire was developed with reference to the Theoretical Domains Framework and administered to critical care nurses in 15 hospitals across eastern, southern, western, northern, and central geographical areas of China from 20 February 2023 to 16 March 2023. Data were collected for personal demographics, clinical practice status, and from Likert-type responses about barriers to and facilitators of implementing individualized repositioning frequency.

RESULTS

In total, 574 effective questionnaires were collected. Only 3.8 % of respondents reported that their hospital/ward uses an individualized repositioning frequency rule. Six facilitator domains identified were: social/professional role and identity; beliefs about capabilities; optimism; beliefs about consequences; reinforcement; and intentions. Seven barrier domains were: knowledge; skills; goals; memory, attention and decision processes; environmental context and resources; social influences; and behavioral regulation. Inferential analysis showed that critical care nurses who had higher degrees, more years of work, more environmental support, and more nursing experience were prone to being more positive in response to the implementation of individualized repositioning frequency.

CONCLUSION

The clinical practice status of implementing individualized repositioning frequency among critical care nurses in China is unsatisfactory. Implementation is essential but complex and is influenced by several factors. Theory-based suggestions for improving this situation are provided on the basis of identified barriers.
