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

COVID-19 and Hospital-Acquired Pressure Injuries: A Systematic Review

OBJECTIVE

To investigate the relationship between COVID-19-related variables and hospital-acquired pressure injury (HAPI) incidence.

DATA SOURCES

The authors searched four databases: Cochrane, MEDLINE, EMBASE, and CINAHL. The literature search contained key terms such as "COVID-19," "hospital-acquired pressure injuries," "pressure ulcer," "pressure injury," "decubitus ulcer," and "hospitalization."

STUDY SELECTION

The systematic search of the literature identified 489 publications that matched the inclusion criteria. Articles were included in the review if they were peer-reviewed publications that reported HAPI incidence for patients who were hospitalized and COVID-19 positive. Two reviewers performed the screen simultaneously, and 19 publications were included.

DATA EXTRACTION

Two reviewers followed a standardized extraction form that included study and patient characteristics, COVID-19 status, HAPI characteristics, prone positioning, length of hospitalization, and HAPI prevention and treatment strategies.

DATA SYNTHESIS

The authors carried out a narrative synthesis of the extracted data because the data obtained were too heterogeneous for meta-analysis. The primary outcome was HAPI incidence.

CONCLUSIONS

This review identified that HAPI incidence was high among men who were COVID-19 positive, had longer hospital stays, experienced prone positioning, and had care teams without a skin and wound care expert. Future research should use more robust methodology and focus on quantitative modeling to iteratively improve inpatient HAPI guidelines.

Nurses' and nursing students' knowledge and attitudes to pressure injury prevention: A meta-analysis based on APUP and PUKAT

BACKGROUND

Morbidity and mortality among patients due to pressure injuries continue to rise. Nurses play a critical role in preventing pressure injuries. However, published results on nurses' knowledge and attitudes for pressure injury prevention are often contradictory.

OBJECTIVES

To conduct a meta-analysis of nurses' and nursing students' knowledge and attitudes toward pressure injury prevention.

DESIGN

A meta-analysis of cross-sectional studies.

DATA SOURCES

Ten databases were queried for the meta-analysis. The search period was from the time of the databases' establishment to February 2023.

REVIEW METHODS

This review followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The Agency for Healthcare Research and Quality (AHRQ) was used to assess the methodological quality of the included studies. Statistical analysis was conducted with the Stata 15.0 software, and the quantitative data of knowledge and attitude toward preventing PI in all studies were summarized.

RESULTS

Thirteen studies from 9 countries were included. The meta-analysis showed that nurses and nursing students had low knowledge but positive attitudes toward pressure injury prevention. Subgroup analysis showed that the pooled proportion of both knowledge and attitudes was higher in Asia than in Europe. Nurses had higher knowledge than nursing students, however, the former had a more negative attitude than the latter. Sensitivity analyses were robust. Egger's test showed no significant publication bias.

CONCLUSION

The knowledge of nurses and nursing students about pressure injury prevention is not promising and there is an urgent need for continuous learning. Attitudes are more positive but there is room for improvement. The relevant departments should strengthen nurses' and nursing students' knowledge of pressure injury prevention and further improve their attitudes toward pressure injury prevention.

A Review of Epidermal Flexible Pressure Sensing Arrays

In recent years, flexible pressure sensing arrays applied in medical monitoring, human-machine interaction, and the Internet of Things have received a lot of attention for their excellent performance. Epidermal sensing arrays can enable the sensing of physiological information, pressure, and other information such as haptics, providing new avenues for the development of wearable devices. This paper reviews the recent research progress on epidermal flexible pressure sensing arrays. Firstly, the fantastic performance materials currently used to prepare flexible pressure sensing arrays are outlined in terms of substrate layer, electrode layer, and sensitive layer. In addition, the general fabrication processes of the materials are summarized, including three-dimensional (3D) printing, screen printing, and laser engraving. Subsequently, the electrode layer structures and sensitive layer microstructures used to further improve the performance design of sensing arrays are discussed based on the limitations of the materials. Furthermore, we present recent advances in the application of fantastic-performance epidermal flexible pressure sensing arrays and their integration with back-end circuits. Finally, the potential challenges and development prospects of flexible pressure sensing arrays are discussed in a comprehensive manner.

Nursing interventions in preventing pressure injuries in acute inpatient care: a cross-sectional national study

BACKGROUND

Several nursing interventions for pressure injury prevention have been identified, including risk and skin status assessment. The aim of this study was to explore prevention of pressure injuries in Finnish acute inpatient care. The data were collected on pressure injury risk and skin status assessments, repositioning, the use of support surfaces, preventive skin care, malnutrition risk assessment, and nutritional care.

METHODS

This multicentre, cross-sectional study was conducted in 16 acute care hospitals, excluding psychiatric care. Adult patients from inpatient care were recruited on the annual international Stop Pressure Ulcers Day in 2018 and 2019. Enrolment covered 6,160 participants in 503 units. Descriptive statistics were used to describe pressure injuries, risk assessments, and preventive nursing interventions. Cross tabulation, Pearson's chi-square and Fisher's exact tests were also used. Reporting follows the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

RESULTS

In all, 30% of the participants had their pressure injury risk assessed during the care, and for 19% within 8 h after admission. The same time limit in risk assessment was fulfilled for 16% of the participants with a pressure injury, and 22% of the participants using a wheelchair or being bedridden. A skin status assessment within 8 h after admission was conducted for 30% of all participants, and for 29% of the participants with a pre-existing pressure injury, and for 38% of the participants using a wheelchair or being bedridden. The risk of malnutrition was screened in 20% of the participants. Preventive interventions were targeted to participants with a pressure injury instead of patients with a high-pressure injury risk.

CONCLUSION

This study adds evidence about pressure injury risk assessments and the implementation of preventive nursing interventions in Finnish acute care. Skin status and pressure injury risk assessments were irregularly conducted, and the outcome was not used by nurses to guide the implementation of preventive interventions. The results reveal the gaps in evidence-based nursing practice, which require further efforts to prevent pressure injuries. Improving the national focus on pressure injury prevention practice is critical for improving healthcare for our patients.

The effects of educational intervention on patient participation in pressure injury prevention: a pilot study

OBJECTIVE

Patients' roles in reducing pressure injuries (PIs) are emphasised in clinical guidelines, although patients' preferences are undetermined. This study evaluated the effects of a pilot six-month educational intervention on patient participation in PI prevention.

METHOD

A convenience sampling method was used to select patients admitted to medical-surgical wards at one of the teaching hospitals in Tabriz, Iran. This is a one-group pre-test and post-test interventional study, conducted via quasi-experimental design. Using a pamphlet, patients received education in preventing PIs. Data collected before and after intervention through a questionnaire were analysed using descriptive and inferential statistics (McNemar and paired t-tests) in SPSS software (IBM Corp., US).

RESULTS

The study cohort consisted of 153 patients. Findings revealed that the knowledge of the patients about PIs, patients' ability to talk with the nurses, information received about PIs, and patients' ability to participate in decisions related to PI prevention had significantly increased following the intervention (p<0.001).

CONCLUSION

Educating patients can improve their knowledge to enable them to participate in PI prevention. The findings of this study suggests further research is necessary on factors influencing patients' participation in such self-care behaviours.

Effect of a prophylactic dressing for sacral pressure injuries in non-critically ill patients after general surgery: A randomized controlled trial

BACKGROUND

Hospital-acquired pressure injuries are strongly associated with surgeries performed under general anesthesia.

AIMS

The aim of this study was to evaluate the effects of using a prophylactic multi-layer soft silicone foam dressing in non-critically ill patients with a Braden Scale score of ≤18 after undergoing routine surgery without sacral pressure injuries.

METHODS

This randomized controlled trial included 156 patients who were admitted for surgery under general anesthesia in a tertiary general hospital. The patients were divided into a control group and an intervention group. A 5-layer soft silicone foam dressing was applied to the sacrum of patients in the intervention group immediately after surgery. For the control group, standard pressure injury prevention activities were performed alongside standard care without preventive dressings.

RESULTS

There were no significant differences in general and clinical characteristics between the two groups; however, the incidence of pressure injury and blanching erythema was higher in the control group, showing a significant difference from the experimental group. Factors influencing the development of pressure injuries and blanching erythema through multivariate regression analysis were prophylactic dressing application and Braden Scale score at the time of admission. A statistically significant difference was noted in survival time from pressure injury between both groups.

LINKING EVIDENCE TO ACTION

The incidence of pressure injuries and blanching erythema was lower when the prophylactic dressing was applied with standard protocol for general ward patients after surgery. Accurate evaluation of the patient's skin condition and pressure injury risk assessment before surgery are important. Progressive prophylactic dressings to prevent pressure injuries are effective, and tailored nursing interventions based on accurate assessment of patient's skin condition and risk factors are essential for maintaining skin integrity.

Barriers and facilitators to pressure injury prevention in hospitals: A mixed methods systematic review

OBJECTIVE

To systematically synthesize research evidence on barriers and facilitators to pressure injury prevention in hospital settings.

METHODS

A systematic literature review of quantitative, qualitative, and mixed methods research was undertaken using PubMed, MEDLINE, Embase, CINAHL, and Cochrane Library. Studies that reported barriers or/and facilitators to pressure injury prevention in the acute care settings and published in English from 2008 to 2022 were included. Studies were excluded if they were conducted in residential care facilities and nursing homes, or other long-term community care settings. Two authors independently screened articles against the inclusion and exclusion criteria. Quality appraisal was conducted by two authors by using the Mixed Methods Appraisal Tool. Reported results were mapped to the Theoretical Domains Framework to identify the barriers and facilitators to pressure injury prevention.

RESULTS

A total of 78 studies were included. There were 65 quantitative studies, 11 qualitative studies, and two mix-methods studies. The most salient Theoretical Domains Framework domains identified in this review were "Knowledge", "Skills", "Environmental Context and Resources", "Optimism", "Social/Professional Role and Identity", and "Social influences".

CONCLUSION

The barriers and facilitators to pressure injury prevention in hospital settings identified in this systematic review were diverse, and included issues at both individual and organizational level. Healthcare organizations can address the barriers and facilitators from the influential Theoretical Domains Framework domains. Future research is required to investigate the effectiveness of behaviour change interventions that specifically target these barriers and facilitators to pressure injury prevention.

Nutritional status as a predictor of the incidence of pressure injury in adults: A systematic review and meta-analysis

AIM

Pressure injuries are a significant health care problem worldwide, and many factors influence their occurrence and development. The purpose of this systematic review and meta-analysis was to investigate the role of nutritional status in the development rate of pressure injuries as a potentially modifiable risk factor.

METHODS

Study designs included cohort (prospective and retrospective), case-control, and RCTs if the association between nutrition status and pressure injuries was reported. Databases searched included: PubMed, CINAHL, Embase, Scopus, Web of Science, and Cochrane Library on April 20th, 2022. The data were analyzed using OR and random effect model in Revman5.3 and STATA 15 Software. Report this systematic review and meta-analysis according to the PRISMA 2020 statement.

RESULTS

A total of 22 separate studies were retained in this systematic review. Of these, 16 articles were included in the meta-analysis. Three studies were assessed as low risk and sixteen as a moderate risk of bias. All RCTs were B quality. The odds ratio of the incidence of pressure injuries in malnourished and non-malnourished patients was 3.66(95% CI: 2.77-4.83). In the three RCTs studies(n = 870), the odds ratio of the incidence of pressure ulcers in patients with standard nutrition to those with specific nutritional interventions was 1.35(95%CI:1.02-1.78).

CONCLUSIONS

This systematic review and meta-analysis showed that nutritional status is significantly associated with pressure injuries. Malnutrition can increase the incidence of pressure injuries, and specific nutritional interventions can reduce the incidence of pressure injuries compared to standard nutrition.

Retrospective matched cohort study of incidence rates and excess length of hospital stay owing to pressure injuries in an Asian setting

Background

Little is known about stage 1 and 2 pressure injuries that are health care-acquired. We report incidence rates of health care-acquired stage 1 and stage 2 pressure injuries, and, estimate the excess length of stay using four competing analytic methods. We discuss the merits of the different approaches.

Methods

We calculated monthly incidence rates for stage 1 and 2 health care-acquired pressure injuries occurring in a large Singapore acute care hospital. To estimate excess stay, we conducted unadjusted comparisons with a control cohort, performed linear regression and then generalized linear regression with a gamma distribution. Finally, we fitted a simple state-based model. The design for the cost attribution work was a retrospective matched cohort study.

Results

Incidence rates in 2016 were 0.553% (95% confidence interval [CI] 0.55, 0.557) and 0.469% (95% CI 0.466, 0.472) in 2017. For data censored at 60 days' maximum stay, the unadjusted comparisons showed the highest excess stay at 17.68 (16.43-18.93) days and multi-state models showed the lowest at 1.22 (0.19, 2.23) days.

Conclusions

Poor-quality methods for attribution of excess length of stay to pressure injury generate inflated estimates that could mislead decision makers. The findings from the multi-state model, which is an appropriate method, are plausible and illustrate the likely bed-days saved from lowering the risk of these events. Stage 1 and 2 pressure injuries are common and increase costs by prolonging the length of stay. There will be economic value investing in prevention. Using biased estimates of excess length of stay will overstate the potential value of prevention.

Expression levels of NPPB, ITGB6, CPNE4, EML5, and ITSN1 in fresh exudates swabbed from critically colonised and infected full-thickness wounds in rats

Pressure injury management requires reliable identification of critical colonisation due to lack of infection signs. Our research group previously proposed the mRNAs natriuretic peptide B (Nppb), integrin subunit beta 6 (Itgb6), copine 4 (Cpne4), echinoderm microtubule-associated protein like 5, and intersectin 1 as candidate markers in pooled exudates of critically colonised wounds. However, it is unclear whether mRNAs or proteins of the candidate genes would be suitable as biomarkers in fresh exudate. Therefore, this study aimed to evaluate the validity of the mRNAs and proteins as fresh exudate markers for critical colonisation. Three wound models of normal healing, critical colonisation, and infection were created in rats. Fresh swab-collected exudates were collected, and mRNA and protein expression levels were measured. In the fresh wound exudates, the detection frequency of Itgb6 tended to decrease in the critically colonised and infected wounds (P = .067), and those of Cpne4 and Nppb tended to be lower in the infected wounds than in the normal healing and critically colonised wounds (P = .006 and .067, respectively). In contrast, there was no difference in protein expression in the exudates. This study suggests that Itgb6 mRNA in fresh exudates is a promising biomarker for critical colonisation.

Incidence of the first diabetic foot ulcer: A systematic review and meta-analysis

AIM

Investigate the incidence of the first diabetic foot ulcer.

METHOD

This is a systematic review with meta-analysis of cohort studies following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and using RevMan software. A systematic search of Medline databases via PubMed, Embase, Lilacs, Scopus databases, and Web of Science was performed until July 2021. In addition to investigating the incidence of the first diabetic foot ulcer, the influence of the variables of the Human Development Index (HDI), glycated hemoglobin, and follow-up time of the participants on the incidence of the first diabetic foot ulcer (DFU) was analyzed through meta-regression. For the meta-analysis of cumulative incidence and possible variable associations, RevMan software was used in the Metaprop data package with 95% confidence interval (CI).

RESULTS

A total of 9,772 articles were identified out of which 87 were selected and 12 studies ultimately included in the systematic review and meta-analysis. The meta-analysis of cumulative incidence was 5.65% (95% CI: 4.20; 7.57). By meta-regression, a significant inverse association was identified between DFU incidence and HDI (estimate - 2.38; 95% CI - 4.10--0.67; p = 0.01).

CONCLUSION

The study presents the cumulative incidence for the first DFU, an inexistent datum in the national and international literature, and the HDI was inversely associated with the incidence of DFU.

The change of clinical features and surgical outcomes in patients with pressure injury during the COVID-19 pandemic

This retrospective study aims to explore whether the COVID-19 pandemic altered patient conditions and surgery outcomes by studying 213 pressure injury (PI) patients who underwent surgery during 2016 to 2019 (pre-COVID) and 2020 to 2021 (COVID) in Taiwan. We extracted patient demographics, surgical and blood test records, preoperative vital signs, and flap surgery outcomes. In total, 464 surgeries were performed, including 308 pre-COVID and 156 COVID. During the COVID period, there were more patients presenting with dementia, and it had significantly more patients with >12 000 white blood cells/μL (24.03% vs 15.59%, P = 0.029), higher C-reactive protein levels (7.13 ± 6.36 vs 5.58 ± 5.09 mg/dL, P = 0.014), pulse rates (86.67 ± 14.76 vs 81.26 ± 13.66 beats/min, P < 0.001), and respiratory rates (17.87 ± 1.98 vs 17.31 ± 2.39 breaths/min, P = 0.009) but lower haemoglobin levels (9.75 ± 2.02 vs 10.43 ± 1.67 mg/dL, P < 0.001) preoperatively. There were no between-group differences in flap surgery outcomes but had fewer flap surgeries during COVID-19. Thus, PI patient condition was generally poor during the COVID-19 pandemic because of reduced access to medical treatment; this problem may be resolved through holistic care during a future pandemic or pandemic-like situation.

Development of a method to identify persistent and blanchable redness by skin blotting in mice

Persistent and blanchable redness (PBR) is not currently included in category I pressure injury (PI), which is defined as non-blanchable redness (NBR). However, PBR progresses to PI in a clinical setting. Therefore, it should be clinically managed as category I PI, and a method to distinctly identify PBR is needed. This study aimed to examine whether PI-related biomarkers can distinguish PRB from transient redness (TR) and NBR using skin blotting. TR, PBR, and NBR models were established by the different conditions of dorsal skin compression. Redness observation and skin blotting were performed, and the skin tissue samples were subjected to histological and molecular biological analyses. The vascular endothelial growth factor (Vegf) b, heat shock protein (Hsp) 90aa1, tumour necrosis factor, interleukin (Il) 1b, and Il6 messenger ribonucleic acid levels were significantly different between the three models. The VEGF-A, VEGF-B, IL-1β, and IL-6 protein levels were different between the three models. Although the results of skin blot examinations were inconsistent with those of the expression analysis of tissue, HSP90α and IL-1β are suggested to be potential markers to distinguish PBR from TR and NBR.

Psychometric validation of the Korean Pressure Ulcer Knowledge Assessment Tool

OBJECTIVE

The purpose of this study was to evaluate the psychometric properties, including content validity, validity of multiple choice items, and the reliability of the Korean version of the Pressure Ulcer Knowledge Assessment Tool (K-PUKAT 2.0), using classical test theory (CTT) and item response theory (IRT).

METHOD

Linguistic validation process and factor analysis were conducted among wound care nurses, staff nurses and nursing students. Items were analysed according to the CTT and IRT using a two-parameter logistic model. Intraclass correlation coefficients were used to examine reliability.

RESULTS

A total of 378 wound care nurses, staff nurses and nursing students participated in this study. While most items showed moderate difficulty based on the CTT, difficulty index values based on the IRT were more broadly distributed (low: 5 items; moderate: 9 items; high: 1 item). The intraclass correlation coefficient for K-PUKAT 2.0 was 0.72.

CONCLUSION

The K-PUKAT 2.0 demonstrated concise and good psychometric properties. Based on the results of this study, repetitive use of K-PUKAT 2.0 will not only help in distinguishing whether an individual has sufficient clinical knowledge, but will also play a key role in supporting learning.

Incidence and Characteristics of Suspected Deep Tissue Pressure Injuries on the Foot and Ankle: A Retrospective Study

PURPOSE

The purpose of this study was to measure the incidence of suspected deep tissue pressure injuries (DTPIs) in patients admitted to the hospital, describe their location, identify the related hospital length of stay, and explore any associations between intrinsic or extrinsic factors relevant to DTPI development.

DESIGN

Retrospective review/audit of clinical data.

SUBJECTS AND SETTING

We reviewed pertinent medical data from patients reported as developing a suspected deep tissue injury during hospital admission from January 2018 to March 2020. The study setting was a large tertiary public health service in Victoria, Australia.

METHODS

Patients who developed a suspected deep tissue injury during hospital admission between January 2018 and March 2020 were identified through the hospital online risk recording system. Data were extracted from the relevant health records, including demographics, admission data, and pressure injury data. The incidence rate was expressed per 1000 patient admissions. Multiple regression analyses were used to determine associations between the time (days) to develop a suspected deep tissue injury and intrinsic (patient level) or extrinsic (hospital level) factors.

RESULTS

Six hundred fifty-one pressure injuries were recorded during the audit period. A minority (9.5%; n = 62) of patients developed a suspected deep tissue injury; all were located on the foot and ankle. The incidence of suspected deep tissue injuries was 0.18 per 1000 patient admissions. The mean length of stay among patients who developed a DTPI was 59.0 (SD = 51.9) days as compared to a mean of 4.2 (SD = 11.8) days for all patients admitted to the hospital during this period. Multivariate regression analysis determined that the longer time (in days) to develop a pressure injury was associated with having a higher body weight (Coef = 0.02; 95% CI = 0.00 to 0.04; P = .043), not having off-loading (Coef =-3.63; 95% CI =-6.99 to -0.27; P = .034), and an increasing number of ward transfers (Coef = 0.46; 95% CI = 0.20 to 0.72; P = .001).

CONCLUSIONS

Findings identified factors that may play a role in the development of suspected deep tissue injuries. A review of risk stratification in health services may be beneficial, with consideration to adjustments of procedural assessments of patients at risk.

Predictive application of foam dressing on preventing of auricle pressure injury caused by ear dressing

Objective

The use of foam dressings has been regarded as part of the individualized care plan in clinical practice. Our study aimed to compare the predictive application of foam dressing and conventional nursing method in the prevention of auricle pressure injury (PI) caused by ear dressing.

Methods

Two hundred and four patients undergoing ear dressing after the operation in the Affiliated Hospital of Southwest Medical University in Sichuan, China from January 2021 to September 2021 were recruited as research objects. Patients were randomized into intervention group (n = 102) and control group (n = 102) using double-blind method.

Result

Results showed that patients in the intervention group showed significantly lower incidence of auricle PI and higher comfort and satisfaction levels than those in the control group (P < 0.05).

Conclusion

Our study reflected effective predictive application of foam dressing in reducing the incidence of auricle PI in ear dressing, which was suitable for clinical application.

Documentation of pressure ulcers in medical records at an internal medicine ward in university hospital in western Sweden

OBJECTIVES

Pressure ulcers cause suffering, prolong care periods, and increase mortality. The aim was to describe and analyze the documentation of pressure ulcers and focused on the medical records from an internal medicine ward in a university hospital in western Sweden.

METHODS

A quantitative, retrospective review of medical records was conducted for all care events (n = 1,458) with descriptive statistics.

RESULTS

Documentation of the pressure ulcers in care plans was 2.1% (n = 31) compared to 6.7 % (n = 46) within final notes written by registered nurses (RN), a lower result compared to PPM (n = 3/14, 21.4%). Risk assessments were carried out in 68 (4.7%) care events, and 31 care plans included pressure ulcers. Moreover, 198 cases of tissue damage were documented, 43 (21.7%) defined as pressure ulcers, the other 147 (74.2%) lacked definition.

CONCLUSIONS

Differences (2.1%-21.4%) highlight improvements; knowledge and communication of pressure ulcers ensure reliable documentation in medical records.

Pressure injury prevention in the operating unit of a Swiss university hospital: a best practice implementation project

OBJECTIVES

The aim of this project was to promote best practice in pressure injury prevention for patients during the intraoperative period in the main operating unit of a Swiss tertiary hospital, through improving risk assessment, safe positioning and documentation.

INTRODUCTION

Pressure injury is a common and serious complication of surgery patients. Despite pressure injuries being mostly preventable, they are not a top priority of operating room professionals.

METHODS

A baseline audit was conducted using the JBI Practical Application of Clinical Evidence System, applying nine evidence-based criteria. The audit was followed by the implementation of multiple strategies to promote best practice in pressure injury prevention. A follow-up audit was conducted to determine the compliance with best practice recommendations.

RESULTS

The baseline audit indicated poor compliance with evidence-based practice in most audited criteria. The project team identified barriers to best practice and strategies implemented to improve practice, including tailored education, direct support in each surgery specialty, assignment of responsibilities regarding pressure injury prevention measures among the multidisciplinary team members and multiple channels of communication. Improvements in practice were observed in eight of nine criteria in the follow-up audit.

CONCLUSION

The project demonstrated important positive changes in pressure injury prevention during the intraoperative period, despite a sharp slowdown in its implementation process. Continuing education for nursing and nonnursing practitioners has been systematized. Follow-up audits will need to be conducted in the future to maintain pressure injury prevention processes, and contribute to safety of care in adult patients during the perioperative period.

Characteristics of COVID-19 patients who developed pressure injuries: a scoping review

OBJECTIVE

To describe the characteristics of patients with COVID-19 who developed pressure injuries (PIs), the characteristics of PIs experienced, and the incidence and prevalence of PIs among the patients with COVID-19. PIs are associated with increased morbidity, mortality and healthcare expense. PIs have been reported among patients who have contracted COVID-19. Understanding the characteristics of COVID-19 patients, and how PIs are prevented and managed, may inform care and optimise the outcomes for COVID-19-positive patients.

METHOD

A scoping review was conducted. All study designs, including grey literature, published in the English language from December 2019 to March 2021, reporting on patients with COVID-19 and PIs, were included.

RESULTS

In total, 27 publications (n=4820 patients) were included in the review. The reported incidence rate of PIs was 7.3-77.0%. The causative factors noted were: prone positioning (28.5%); medical devices (21.4%); and medical devices used during prone positioning (14.2%). The most common PI sites were the cheeks (18.7%). PIs occurred on average at 14.7 days post-acute care admission. Of the PIs where staging information was specified (67.7%), the most common was Stage 2/II (45.2%). PI risk may intensify on account of the intrinsic mechanism of COVID-19-associated intensive care treatment.

CONCLUSION

PI prevention and management should be prioritised for patients with COVID-19, given the reported high prevalence of PIs and exacerbated risk arising from the use of prone position and medical devices. Further research is required to understand the association between COVID-19 and PIs, and to guide effective prevention and treatment approaches.

Accuracy of Thermographic Imaging in the Early Detection of Pressure Injury: A Systematic Review

OBJECTIVE

To verify the accuracy of thermographic images in the early detection of pressure injury (PI) in adult patients.

DATA SOURCES

Between March 2021 and May 2022, researchers searched 18 databases for relevant articles using nine keywords. In total, 755 studies were evaluated.

STUDY SELECTION

Eight studies were included in the review. Studies were included if they evaluated individuals older than 18 years who were admitted to any healthcare setting; were published in English, Spanish, or Portuguese; examined the accuracy of thermal imaging in the early detection of PI, including suspected stage 1 PI or deep tissue injury; and they compared the region of interest to another area or control group, or to the Braden Scale or Norton Scale. Animal studies and reviews, studies with contact infrared thermography, and those including stages 2, 3, 4, and unstageable PIs were excluded.

DATA EXTRACTION

Researchers examined sample characteristics and assessment measures related to image capture, including environmental, individual, and technical factors.

DATA SYNTHESIS

Across the included studies, sample sizes ranged from 67 to 349 participants, and patients were followed up for periods ranging from a single assessment up to 14 days, or until the appearance of a PI, discharge, or death. Evaluation with the infrared thermography identified temperature differentials between regions of interest and/or in comparison with risk assessment scales.

CONCLUSIONS

Evidence on the accuracy of thermographic imaging in the early detection of PI is limited.

Battery-Free, Wireless, Ionic Liquid Sensor Arrays to Monitor Pressure and Temperature of Patients in Bed and Wheelchair

Repositioning is a common guideline for the prevention of pressure injuries of bedridden or wheelchair patients. However, frequent repositioning could deteriorate the quality of patient's life and induce secondary injuries. This paper introduces a method for continuous multi-site monitoring of pressure and temperature distribution from strategically deployed sensor arrays at skin interfaces via battery-free, wireless ionic liquid pressure sensors. The wirelessly delivered power enables stable operation of the ionic liquid pressure sensor, which shows enhanced sensitivity, negligible hysteresis, high linearity and cyclic stability over relevant pressure range. The experimental investigations of the wireless devices, verified by numerical simulation of the key responses, support capabilities for real-time, continuous, long-term monitoring of the pressure and temperature distribution from multiple sensor arrays. Clinical trials on two hemiplegic patients confined on bed or wheelchair integrated with the system demonstrate the feasibility of sensor arrays for a decrease in pressure and temperature distribution under minimal repositioning.

Nursing students' knowledge towards pressure injury prevention: A cross-sectional study in the north of Morocco

AIM

This study aimed to assess nursing students' knowledge towards pressure injury prevention. The intent is to improve the undegraduate nursing curricula.

MATERIAL AND METHODS

The study adopted a cross-sectional descriptive research design. The study population consisted of 285 nursing students enrolled during the second semester of the 2022 year. The response rate was 84.9%. The authors translated and validated the English version of PUKAT 2.0 into French to collect data. PUKAT-Fr is a French version of PUKAT 2.0. The authors used an information form to gather data about participants' descriptive characteristics and specific educational behaviors. Data analysis was performed through descriptive statistics and non-parametric tests. Ethical procedures were accomplished.

RESULTS

The total mean score of the participants was low (5.88/25). « Prevention of pressure ulcers » and « Specific patient groups » were the most critical themes. Most participants did not use the risk assessment tool in the lab or clinical settings (66.5%) nor the pressure-redistribution mattresses or cushions (43.3%). Education specialization and the number of departments frequented were significantly associated with the participants' total mean score (p < 0.001).

CONCLUSION

The nursing students' knowledge level was low (5.88/25). Curricular and organizational issues were involved. Efforts from faculty and nursing managers could be introduced to ensure evidence-based education and practice.

Influencing factors of medical device-related pressure ulcers in medical personnel during the COVID-19 pandemic: A systematic review and meta-analysis

OBJECTIVE

To determine the influencing factors of medical device related pressure injury (MDRPU) in medical staff by meta-analysis.

METHODS

A comprehensive literature search was conducted by PubMed, Embase, Cochrane Library, Web of Science, CNKI, VIP, CBM, and WanFang Data (from inception to July 27, 2022). Two researchers independently performed literature screening, quality evaluation and data extraction, and meta-analysis was conducted with RevMan 5.4 and Stata12.0 software.

RESULTS

Total of 11215 medical staff were included in 9 articles. Meta analysis showed that gender, occupation, sweating, wearing time, single working time, department of COVID-19, preventive measures, and level 3 PPE were the risk factors for MDRPU in medical staff (P < 0.05).

CONCLUSION

The outbreak of COVID-19 led to the occurrence of MDRPU among medical staff, and the influencing factors should be focused on. The medical administrator can further improve and standardize the preventive measures of MDRPU according to the influencing factors. Medical staff should accurately identify high-risk factors in the clinical work process, implement intervention measures, and reduce the incidence of MDRPU.

A systematic review of prevalence and incidence of pressure ulcers/injuries in hospital emergency services

AIM

To develop a systematic review on the prevalence and the incidence of pressure ulcers/injuries in adult patients in hospital emergency services.

MATERIALS AND METHODS

Systematic review of prevalence and incidence studies developed according to the Preferred Reporting Items Form Systematic Review and Meta-Analysis Protocols and the Joanna Briggs Institute methodology. The inclusion criteria were based on the CoCoPop mnemonic. The main variables of interest were the "prevalence" and/or the "incidence" of "pressure ulcers/injuries" (Condition) reported in studies developed in hospital emergency services (Context) with adult participants (Population). The Systematic Review Protocol was registered in PROSPERO (CDR42021252906).

RESULTS

The pressure ulcer/injury (point) prevalence ranged from 5.2% (at admission) to 12.3% (at discharge) and the pressure ulcer/injury incidence ranged from 4.5% to 78.4%. Most of the pressure ulcers/injuries documented were category/stage I. The most problematic anatomical locations were the sacrococcygeal region and the heels. The preventive measures should be implemented as soon as possible and are important in patients older than 75 years, with multiple comorbidities, high C-Reative Protein levels, cervical spine immobilization, presented to hospital emergency service by ambulance or with hypotension at the time of admission.

CONCLUSIONS

The prevalence and incidence of pressure ulcers/injuries in hospital emergency services remains an understudied topic which could limit the generalization of our data. This systematic review highlighted that the management of pressure ulcers/injuries is a real and current challenge in hospital emergency services. It is important to identify the patients at (higher) risk to establish an (earlier) preventive care plan according to patients and emergency services' characteristics.

Simultaneous Segmentation and Classification of Pressure Injury Image Data Using Mask-R-CNN

Background

Pressure injuries (PIs) impose a substantial burden on patients, caregivers, and healthcare systems, affecting an estimated 3 million Americans and costing nearly $18 billion annually. Accurate pressure injury staging remains clinically challenging. Over the last decade, object detection and semantic segmentation have evolved quickly with new methods invented and new application areas emerging. Simultaneous object detection and segmentation paved the way to segment and classify anatomical structures. In this study, we utilize the Mask-R-CNN algorithm for segmentation and classification of stage 1-4 pressure injuries.

Methods

Images from the eKare Inc. pressure injury wound data repository were segmented and classified manually by two study authors with medical training. The Mask-R-CNN model was implemented using the Keras deep learning and TensorFlow libraries with Python. We split 969 pressure injury images into training (87.5%) and validation (12.5%) subsets for Mask-R-CNN training.

Results

We included 121 random pressure injury images in our test set. The Mask-R-CNN model showed overall classification accuracy of 92.6%, and the segmentation demonstrated 93.0% accuracy. Our F1 scores for stages 1-4 were 0.842, 0.947, 0.907, and 0.944, respectively. Our Dice coefficients for stages 1-4 were 0.92, 0.85, 0.93, and 0.91, respectively.

Conclusions

Our Mask-R-CNN model provides levels of accuracy considerably greater than the average healthcare professional who works with pressure injury patients. This tool can be easily incorporated into the clinician's workflow to aid in the hospital setting.

A systematic evaluation of methodological and reporting quality of meta-analysis published in the field of gastrointestinal endoscopy

BACKGROUND

To evaluate the methodological and reporting quality of published meta-analyses (MAs) in four major gastrointestinal endoscopic journals, and identify the predicted factors for high quality.

METHODS

A systematic search was performed in PubMed to identify MAs from 1, January, 2016 to 31, December, 2020 in four major gastrointestinal endoscopic journals (including Digestive Endoscopy, Gastrointestinal Endoscopy, Surgical Endoscopy, and Endoscopy). We collected the characteristics of MAs after filtering unqualified articles, and assessed methodological and reporting qualities for eligible articles by AMSTAR tool and PRISMA checklist, respectively. Logistic regression was used for identifying predictive factors for high quality.

RESULTS

A total of 289 MAs were identified after screening by predefined inclusion and exclusion criteria. The scores (mean ± SD) of AMSTAR and PRISMA were 7.73 ± 1.11 and 22.90 ± 1.85, respectively. In PRISMA checklist, some items had less than 50% complete adherence, including item 2 (structured summary), items 5 (protocol and registration), items 12 and 19 (risk of bias in studies), item 27 (funding support). Item 1 (a priori design), item 4 (gray literature research), item 5 (list of included and excluded) were inferior to 50% adherence in AMSTAR tool. We found the predictive factors for high quality through logistic regression analysis: a priori design and funding support were associated with methodological quality. Protocol and registration influenced the methodological and reporting quality closely.

CONCLUSION

In general, qualities on the methodology and the reporting of MAs published in the gastrointestinal endoscopic journals are good, but both of which still potentially need further improvement.

EffEctiveness of Prophylactic fOam dressings in the prevention of saCral pressure injuries in at-risk hospitalised patients: the EEPOC trial

BACKGROUND

Prophylactic dressings are increasingly used to prevent pressure injuries in hospitalised patients. However, evidence regarding the effectiveness of these dressings is still emerging. This trial aims to determine the clinical and cost-effectiveness of a prophylactic silicone foam border dressing in preventing sacral pressure injuries in medical-surgical patients.

METHODS

This is a multicentre, pragmatic, parallel group, randomised controlled trial. A sample size of 1320 was calculated to have >90% power to detect a 5% difference in the primary outcome at an alpha of 0.05. Adult patients admitted to participating medical-surgical wards are screened for eligibility: ≥18 years, admitted to hospital within the previous 36 h, expected length of stay of ≥24 h, and assessed high risk for hospital-acquired pressure injury. Consenting participants are randomly allocated to either prophylactic silicone foam dressing intervention or usual care without any dressing as the control group via a web-based randomisation service independent of the trial. Patients are enrolled across three Australian hospitals. The primary outcome is the cumulative incidence of patients who develop a sacral pressure injury. Secondary outcomes include the time to sacral pressure injury, incidence of severity (stage) of sacral pressure injury, cost-effectiveness of dressings, and process evaluation. Participant outcomes are assessed daily for up to 14 days by blinded independent outcome assessors using de-identified, digitally modified sacral photographs. Those who develop a sacral pressure injury are followed for an additional 14 days to estimate costs of pressure injury treatment. Analysis of clinical outcomes will be based on intention-to-treat, per-protocol, and sensitivity analyses.

DISCUSSION

This trial aims to provide definitive evidence on the effect prophylactic dressings have on the development of hospital-acquired sacral pressure injuries in medical-surgical patients. A parallel economic evaluation of pressure injury prevention and treatment will enable evidence-informed decisions and policy. The inclusion of a process evaluation will help to explain the contextual factors that may have a bearing on trial results including the acceptability of the dressings to patients and staff. The trial commenced 5 March 2020 and has been significantly delayed due to COVID-19.

COVID-19 and Hospital-Acquired Pressure Injuries: A Systematic Review

OBJECTIVE

To investigate the relationship between COVID-19 related variables and hospital-acquired pressure injuries (HAPI) incidence.

DATA SOURCES

The authors searched four databases: Cochrane, MEDLINE, EMBASE, and CINAHL. The literature search contained key terms such as COVID-19, hospital-acquired pressure injuries, pressure ulcer, pressure injury, decubitus ulcer, and hospitalization.

STUDY SELECTION

The systematic search of the literature identified 489 publications that matched the inclusion criteria. This included peer-reviewed publications that reported HAPI incidence for patients who were hospitalized and COVID-19 positive. Two reviewers performed the screen simultaneously and 19 publications were included.

DATA EXTRACTION

Two reviewers followed a standardized extraction form that included study and patient characteristics, COVID-19 status, HAPI characteristics, prone positioning, length of hospitalization, and HAPI prevention and treatment strategies.

DATA SYNTHESIS

A narrative synthesis of the extracted data was carried out because the data obtained were too heterogeneous for meta-analysis. The primary outcome was HAPI incidence.

CONCLUSIONS

This review identified that HAPI incidence was high among men who were COVID-19 positive, had longer hospital stays, experienced prone positioning, and had care teams without a skin and wound care expert. Future research should employ more robust methodology and focus on quantitative modeling to iteratively improve in-patient HAPI guidelines.

Retrospective analysis of the management of pelvic decubitus ulcers and their outcomes

Background

Many patients with decubitus-related osteomyelitis are ineligible for myocutaneous flapping, and optimal management in this population is unknown. We describe treatments and outcomes of hospitalized patients with decubitus ulcer-related osteomyelitis who did not undergo surgical reconstruction or coverage.

Methods

We systematically identified hospitalized patients with diagnoses of pelvic, sacral, or femoral osteomyelitis due to decubitus ulceration between 1 January 2018 and 31 December 2018. Demographics, comorbidities, laboratory data, and outcomes were collected by manual chart review. T-tests or Chi-square tests were used for descriptive statistical comparisons; logistic regressions were used to explore the odds of readmission, osteomyelitis-related readmission, and death.

Results

Of 89 patients meeting inclusion criteria, 34 (38%) received surgical debridement and ⩾6 weeks of antibiotics; 55 (62%) received either antibiotics alone or debridement and <6 weeks of antibiotics. Mean age was 55 (standard deviation 18) years, 55% of patients were male, and 69% had spinal cord injury or other form of paralysis. Within 1 year, 56 (63%) patients were readmitted, 38 (44%) patients were readmitted due to complications from osteomyelitis, and 15 (17%) died. We found no significant differences in readmission (OR = 1.33, 95% CI: 0.54-3.21, p = 0.53), readmission related to osteomyelitis (OR = 1.64, 95% CI: 0.69-4.04, p = 0.27), subsequent sepsis (OR = 2.27, 95% CI: 0.83-6.93, p = 0.13), or death (OR = 2.88, 95% CI: 0.83-13.4, p = 0.12) by treatment group.

Conclusions

Among patients with decubitus-related osteomyelitis who did not undergo myocutaneous flapping, outcomes were generally poor regardless of treatment, and not significantly improved with prolonged antibiotics. Prospective studies are needed to assess best practice strategies for this challenging patient population.

Electronic Alert Signal for Early Detection of Tissue Injuries in Patients: An Innovative Pressure Sensor Mattress

Monitoring the early stage of developing tissue injuries requires intact skin for surface detection of cell damage. However, electronic alert signal for early detection is limited due to the lack of accurate pressure sensors for lightly pigmented skin injuries in patients. We developed an innovative pressure sensor mattress that produces an electronic alert signal for the early detection of tissue injuries. The electronic alert signal is developed using a web and mobile application for pressure sensor mattress reporting. The mattress is based on body distributions with reference points, temperature, and a humidity sensor to detect lightly pigmented skin injuries. Early detection of the pressure sensor is linked to an electronic alert signal at 32 mm Hg, a temperature of 37 °C, a relative humidity of 33.5%, a response time of 10 s, a loading time of 30 g, a density area of 1 mA, and a resistance of 7.05 MPa (54 N) at 0.87 m³/min. The development of the innovative pressure sensor mattress using an electronic alert signal is in line with its enhanced pressure detection, temperature, and humidity sensors.

Biomarkers and clinical features associated with pressure injury among geriatric patients

<b>Purpose:</b> The study aims to identify biomarkers and clinical features associated with pressure injury (PI) among geriatric patients.<br /> <b>Methods:</b> A cross-sectional study including 191 patients aged ≥60 years. Patients were classified into those with and without PI. Assessing the risk of PI was performed on admission by applying the Braden scale (BS) for predicting pressure sore risk. Clinical history, baseline hematology, and biochemistry results were obtained. C-reactive protein to albumin ratio (CAR) and Charlson comorbidity index (CCI) were calculated. Statistical analyses were performed.<br /> <b>Results: </b>43 (22.5%) patients had PI. PI was significantly associated with higher CCI, total leukocyte count, and CAR, besides lower BS scores, serum albumin, and total proteins. Significant comorbidities were diabetes mellitus, stroke/transient ischemic attack, dementia, incontinence, and chronic kidney disease. The optimal cut-offs for PI occurrence were ≤14, ≤3.1 g/dl and &gt;1.27 for BS, albumin, and CAR, respectively.

Turning and Repositioning Frequency to Prevent Hospital-Acquired Pressure Injuries Among Adult Patients: Systematic Review

Turning and repositioning is considered one of the strategies to reduce the incidence of pressure injuries (PIs) among hospitalized patients, as it helps to redistribute and minimize direct pressure on the targeted skin and enhance blood perfusion in the affected areas. The frequency of turning and repositioning is generally uniform across clinical settings, with most clinical guidelines recommending a substantial change in a patient's position according to their health status. Notably, the optimal time interval between the position changes has not yet been established. Therefore, this study aimed to review the current literature in relation to the frequency of turning and repositioning adult patients to prevent PIs. The author used a systematic review following Whittemore and Knafl's review strategy. The author used the following databases: CINAHL, Scopus, PubMed, ProQuest, Ovid, MedLine, Web of Science, and Google Scholar. During the search, Boolean logic operators, MeSH terms, and keywords were utilized. The researcher followed the Johns Hopkins Nursing Evidence-based Practice Grading Scale to evaluate the quality of selected studies. The search yielded 723 articles, of which 10 were included in this review. These 10 articles revealed several frequency intervals for comparison purposes: 2-hourly, 3-hourly, 4-hourly, and 6-hourly depending on the healthcare setting, with a combination of supine, 30° tilt, or 90° tilt. This review shows that the optimal frequency of turning and repositioning to prevent PIs remains unclear and further investigation is necessary. Considering the varying nature of clinical settings, there is a lack of clarity regarding a golden standard for the same. Therefore, patients' health conditions should be considered when choosing the proper frequency to prevent PIs.

Incidence of facial pressure injuries in health-care professionals during the COVID-19 pandemic: A systematic review and meta-analysis

AIM

To evaluate the incidence of facial pressure injuries in health-care professionals during the COVID-19 pandemic in a meta-analysis.

METHODS

Related studies were obtained through electronic databases, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) Chinese Scientific Journal (VIP) China Biomedical Literature service systems (CBM) and Wanfang Data (from inception to 27 November 2021). The pooled incidence and the 95% confidence interval of facial pressure injuries were calculated with Review Manager v5.4 software.

RESULTS

Overall, 16 studies with 14 430 health-care professionals were included. Pooled results showed that the pooled incidence of facial pressure injury in health-care professionals was 58.8% (95% CI: 49.0%-68.7%; p < 0.01). The results of the subgroup analysis showed that the incidence of facial pressure injury in these staff was high, and predominantly stage I pressure injury, in the following cases: in health-care professionals who wore personal protective equipment for longer than 4 h, in those without any training experience, and on the nose.

CONCLUSION

Administrators and researchers should pay attention to preventing facial pressure injury related to the wearing of personal protective equipment (PPE) by ensuring all health-care professionals receive training and by limiting prolonged periods of use.

Prevention and management of hospital-acquired pressure injury among patients with lung disease in a hospital: a best practice implementation project

OBJECTIVES

The aim of this project was to promote evidence-based practice in the prevention and management of pressure injury in lung disease patients.

INTRODUCTION

Pressure injury is a crucial quality indicator for hospital care of patients. The pressure injury incidence threshold in the chest wards has been exceeding that of the general ward (0.128%), which may extend patients' hospital stay.

METHODS

Clinical audits were performed using the JBI Practical Application of Clinical Evidence System and Getting Research into Practice (GRiP) audit and feedback tool. Twelve audit criteria representing best practice recommendations for preventing and managing pressure injury among lung disease patients were used. A baseline audit was performed to measure the degree of consistency between existing practice and best practice. This project used the GRiP analysis and multiple strategies to develop care protocols for pressure injury prevention and management. A follow-up audit was conducted to measure changes in clinical practice and pressure injury incidence.

RESULTS

Postimplementation audit compliance rates improved for the following criteria: skin assessment for identifying pressure injury indications (from 31 to 81%), identification of pressure injury risk score/category (from 19 to 88%), employment of nutritional assessment tools (from 8 to 93%), and provision of information regarding oral nutritional supplements (from 23 to 84%). Furthermore, patients learning the pressure injury care protocols (from 48 to 93%), the receipt of additional skin protection measures, and repositioning of vulnerable areas to relieve pressure increased to 100 and 93%, respectively. After project implementation, the monthly pressure injury incidence decreased markedly from 0.075 to 0.021%.

CONCLUSION

The success factors of this project are attributable to leadership, open communication, multiple learning-by-doing strategies, regular audits, and the promotion of patient and family engagement.

Development, dissemination and evaluation of a smartphone-based app for pressure ulcer/injury prevention and treatment for use at the bedside

OBJECTIVE

After launching the 2019 International Pressure Ulcer/Injury Guideline, the National Pressure Injury Advisory Panel (NPIAP), the European Pressure Ulcer Advisory Panel (EPUAP) and the Pan Pacific Pressure Injury Alliance (PPPIA) collaborated with Sensorydata Corp., US, to develop a guideline app (InterPIP App). The app was designed to: present evidence-based guideline recommendations; incorporate search capacities and functionality to facilitate easy access to clinical guidance; provide accessibility in multiple languages; and to be available worldwide at a reasonable price, including opportunities for free access in low-resource countries. This paper describes the development, dissemination and formative evaluation of a mobile app providing evidence-based recommendations for pressure injury prevention, assessment/classification, and treatment at the point of care.

METHOD

An evaluation tool was designed based on a framework developed by Nouri et al. and made available to all app subscribers.

RESULTS

The InterPIP App is currently available in 11 languages and had been downloaded 3616 times by February 2022 in 78 countries. A total of 62 individuals responded to the survey of end-users. In this formal evaluation of user experiences, the app was rated positively on criteria of: information/content; usability; design; functionality; ethics; and security/privacy (median=4 on a 1-5 Likert scale). Overall perceived value was ranked lower with a median of three. Users provided suggestions for ongoing app enhancement.

CONCLUSION

The InterPIP App offers a unique opportunity to bring evidence-based guidance to the point of care. Formal evaluation of end-user experiences identified opportunities for quality improvement, and informed plans for future development and evaluation.

Nationwide time-series surveys of pressure ulcer prevalence in Japan

OBJECTIVE

The Japanese Society of Pressure Ulcers (JSPU) has two purposes: first, to improve knowledge and skills among health professionals related to preventing and managing pressure ulcers (PUs); and second, to represent those in the field managing PUs, including with government and health authorities. Since 2006, JSPU has conducted fact-finding surveys about every four years to identify PU prevalence in Japan (2006, 2010, 2013 and 2016). Based on the prevalence identified by these surveys, an attempt was made to validate the achievements of JSPU's activities.

METHOD

Information from one-day surveys of hospitals, long-term care health facilities, long-term care welfare facilities, and home visit nursing care stations was analysed. We used generalised estimating equations to estimate the proportions of PUs and their 95% confidence intervals (CIs) for each survey.

RESULTS

A total of 662,419 patients in 2631 facilities participated in the surveys. The estimated proportions for all facilities (95% CI) in chronological order, from the first to the fourth survey, were: 2.67% (2.52-2.83); 2.61% (2.43-2.80); 1.99% (1.83-2.17); and 1.79% (1.65-1.94), respectively. In all facility types, the proportion of PUs was lower in the fourth survey than the first survey.

CONCLUSION

The proportion of PUs showed a decreasing trend and was low according to global standards, demonstrating the efficacy of JSPU's activities.

Effectiveness of an E-Book App on the Knowledge, Attitudes and Confidence of Nurses to Prevent and Care for Pressure Injury

AIMS

This study evaluates the effectiveness of an interactive E-book app training program in improving nurses' knowledge, attitudes, and confidence to prevent and care for pressure injury.

DESIGN

Randomized experimental study.

METHODS

Participants were recruited from a teaching hospital in Taiwan. The study was carried out between 20 March 2014 to 1 April 2016. In total, 164 participants were randomly assigned to a pressure injury E-book app training program (n = 86) or a conventional education program (n = 78) with a one-month follow-up. Outcome variables were levels of pressure injury knowledge, attitudes, and confidence of pressure injury care.

RESULTS

Participants answered 51.96% of the pressure injury knowledge questions correctly before the intervention and 75.5% after the intervention. The pressure injury attitude score was slightly positive, with moderate confidence in pressure injury care. The knowledge, attitudes, and confidence of pressure injury care of the two groups in the pretest and posttest groups increased significantly. Analysis of covariance indicated that nurses in the pressure injury E-book app group had significantly greater improvement in knowledge, attitudes, and pressure injury care confidence as compared with the control group.

CONCLUSION

The pressure injury E-book app interactive training program was effective in improving nurses' knowledge and attitudes toward pressure injury care and in enhancing their confidence in pressure injury care; therefore, this program has potential for nurses' in-service education in both Taiwan and worldwide.

IMPACT

E-book apps allow individuals to control the time and place of learning. Direct observation of procedural skills can provide feedback to trainees on techniques to ensure learning effectiveness and pressure injury care quality.

Validity and reliability of the Chinese version of the Normalization MeAsure Development(NoMAD)

Background

The Normalization MeAsure Development (NoMAD) is a brief quantitative tool based on the Normalization Process Theory (NPT), which can measure the implementation process of new technologies and complex interventions. The aim of our study was to translate and culturally adapt the NoMAD into Chinese, and to evaluate the psychometric properties of the Chinese version of NoMAD.

Methods

According to the NoMAD translation guideline, we undertook forward translation, backward translation, and compared these translations to get a satisfactory result, then we performed cognitive interviews to achieve cross-culture adaptation. And the psychometric properties of the final version were evaluated among clinical nurses who used the pressure injuries management system via WeChat mini-program at a tertiary hospital in northwestern China.

Results

A total of 258 nurses were enrolled in our study, and the response rate was 92.1%. The Cronbach’s alpha of four dimensions were as follow: Coherence (0.768), Cognitive Participation (0.904), Collective Action (0.820), and Reflexive Monitoring (0.808). The overall internal consistency was 0.941. The confirmatory factor analysis results showed a good fit for its theoretical structure (CFI = 0.924, TLI = 0.910, RMSEA = 0.0079, SRMSR = 0.046, χ2/df = 2.61). The item-level content validity index ranged from 0.857 to 1, and the scale-level content validity index was 0.95. There were positive correlations between four constructs scores and three general normalization scores.

Conclusions

The Chinese version of NoMAD is a reliable and valid tool to evaluate the implementation process of innovations.

Swedish translation, cultural adaptation and psychometric evaluation of the pressure ulcer knowledge assessment tool for use in the operating room

The aim of this study was to psychometrically evaluate the Swedish operating room version of PUKAT 2.0. In total, 284 Swedish operating room nurses completed the survey of whom 50 completed the retest. The item difficulty P-value of 14 items ranged between 0.38 and 0.96 (median 0.65). Three items were found to be too easy (0.90-0.96). The D-value of 14 items ranged between 0.00 and 0.42 (median 0.46). Three items had a D-value lower than 0.20 (0.11-0.16) and eight items scored higher than 0.40 (0.45-0.61). The quality of the response alternatives (a-value) ranged between 0.00 and 0.42. This showed that nurses with a master's degree had a higher knowledge than nurses with a professional degree (respectively 9.4/14 versus 8.6/14; t = -2.4, df = 199, P = 0.02). The ICC was 0.65 (95% CI 0.45-0.78). The ICCs for the domains varied from 0.12 (95% CI = -0.16-0.39) to 0.59 (95% CI = 0.38-0.75). Results indicated that 11 of the original items contributed to the overall validity. However, the low participation in the test-retest made the reliability of the instrument low. An extended evaluation with a larger sample should be considered in order to confirm aspects of the psychometric properties of this instrument.

The effect of prone positioning on pressure injury incidence in adult intensive care unit patients: A meta-review of systematic reviews

OBJECTIVE

Numerous systematic reviews have examined the impact of prone positioning on outcomes, including pressure injury (PI). The objective of this meta-review was to synthesise the evidence on the effect of prone positioning on the incidence and location of PIs in adult intensive care unit patients.

REVIEW METHOD

This is a meta-review of published systematic reviews. Five databases were searched; data were extracted by three authors and adjudicated by a fourth. The AMSTAR-2 tool was used to quality appraise the selected articles, which was completed by three authors with a fourth adjudicating.

RESULTS

Ten systematic reviews were synthesised. The cumulative incidence of PI in 15,979 adult patients ranged from 25.7% to 48.5%. One study did not report adult numbers. Only one review reported the secondary outcome of PI location. PIs were identified in 13 locations such as the face, chest, iliac crest, and knees. Using the AMSTAR-2, three reviews were assessed as high quality, six as moderate quality, and one as low quality.

CONCLUSION

The high incidence of PI in the prone position highlights the need for targeted preventative strategies. Care bundles may be one approach, given their beneficial effects for the prevention of PI in other populations. This review highlights the need for proactive approaches to limit unintended consequences of the use of the prone position, especially notable in the current COVID-19 pandemic.

The effect of sub-epidermal moisture on pressure injury prevention strategies and incidence of pressure injuries: A feasibility pilot randomised controlled trial

AIM

Sub-epidermal moisture scanning (SEMS) is a novel point-of-care technology that measures localised oedema and detects early tissue damage that may develop into a pressure injury (PI). It provides objective data that may assist PI prevention (PIP) decision making. This study aimed to determine the feasibility of undertaking a definitive randomised controlled trial (RCT) to test the effectiveness of SEMS.

MATERIALS AND METHODS

This pilot RCT recruited medical and surgical patients at risk of developing a PI in one Australian hospital. All participants received routine PIP care and daily visual skin assessment to determine the presence of a PI. The intervention group also received daily SEMS. Clinical staff were told if the sub-epidermal moisture (SEM) value was abnormal but were not given advice for PIP. Blinding of patients, care staff and outcome assessors was not practical. Feasibility outcomes included recruitment, retention, intervention fidelity, and patient outcomes.

RESULTS

Of 1185 patients screened prior to eligibility, 950 were excluded (80%); 235 were then assessed for eligibility and 160 met the inclusion criteria (68.1%); 100 were recruited (70.0%) and randomised and 99 completed the trial (intervention n = 50; control n = 49) with one person withdrawn due to inappropriate recruitment (100% retention). Of the 657 expected SEMS observations, 598 were completed (91% intervention fidelity). Only 34 of 454 (7.4%) patient outcome data points were missing.

CONCLUSIONS

Most feasibility criteria were met, indicating a definitive trial to assess the effectiveness of SEMS in a medical-surgical patient population is realistic. However, recruitment may be resource intensive and require specific strategies.

Incidence of pressure injuries in fracture patients: A systematic review and meta-analysis

OBJECTIVE

To systematically evaluate the incidence of pressure injuries (PIs) in hospitalized fracture patients and to provide evidence for the prevention and treatment of PIs.

METHODS

A systematic review and meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. Electronic databases including PubMed, Embase, the Cochrane Library, Web of Science, CINAHL, China Knowledge Resource Integrated Database (CNKI), WanFang Database, Weipu Database (VIP), and Chinese Biomedical Database (CBM) were searched to collect cross-sectional studies and cohort studies related to PIs among hospitalized fracture patients. All electronic literature sources were searched from inception to March 2022, and a hand-search through references was also conducted to find relevant articles. Studies were evaluated independently by two researchers and audited by a third researcher. The data were extracted and presented in tables. The risk of bias was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist. All data analysis used Stata14.0. The I² statistic and random-effects model were used to determine the heterogeneity.

RESULTS

A total of 7906 articles were screened, and 18 studies with 8956 patients were ultimately involved in this review. The pooled incidence of PIs in the fracture patients was 20.4% (95%CI: 14.9 to 25.8), and the incidence of PIs only in spinal and hip fracture patients was 23.9% (95%CI: 19.6 to 28.2). The incidence of PIs in 65 years old or over was significantly high (23.3% [95%CI: 15.3 to 31.2]). The most affected body sites were sacrococcygeal regions (56.7%) and heels (19.9%). The most common stages were stage 2 (62.2%) and stage 1 (17.4%).

CONCLUSION

The overall incidence of PIs in fracture patients was as high as 20.4%, significantly higher than the average incidence of adults. We found that the potential for PIs in fracture patients increases with age. Hence, our discoveries recommended that healthcare givers should consider reducing the occurrence of PIs. Additionally, more research may be conducted to improve the understanding of characteristics of PIs among fracture patients and to identify PIs risk factors to prevent and treat them effectively.

Critical Care Nurses’ Knowledge, Attitudes, and Practices Regarding Pressure Injury Treatment: A Nationwide Cross-Sectional Survey

Background

Pressure injury is a common problem in intensive care units. Critical care nurses play an important role in multidisciplinary teams performing pressure injury treatment. Identifying the clinical status of pressure injury treatment may contribute to improving care quality.

Aim

To identify the knowledge, attitudes, and practices regarding pressure injury treatment in critical care nurses.

Design

A cross-sectional survey.

Methods

Secondary data were extracted from a multicenter clinical trial. Knowledge and attitudes toward pressure injury treatment were assessed through a self-administered eight-item questionnaire. The observed practices were recorded using a case report form. The report was in accordance with the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement.

Results

A total of 950 critical care nurses in 15 hospitals from six provinces/municipalities of China were investigated. The mean knowledge score was 2.89 ± 1.16 (95% confidence interval: 2.82–2.97) out of a possible total of 5 points. The correct rates of selecting wound dressings and pain management were 34.4% and 45.6%, respectively. The mean attitude score was 9.07 ± 1.09 (95% confidence interval: 9.00–9.13) out of a possible total of 12 points. A total of 2092 patient days of pressure injury treatment practices were observed and recorded. Repositioning was the most commonly employed treatment measure (98.8%). Foam dressing was the common dressing for stage I (53.6%), stage II (47.5%), and more severe pressure injury (67.9%), including stage III, IV, unstageable, and suspected deep tissue injury.

Conclusion

Critical care nurses exhibited a generally low level of knowledge and moderate attitudes regarding pressure injury treatment. Practices of pressure injury treatment were generally acceptable.

Preventive Measures For pressure injuries: structure of social representations of nursing teams

OBJECTIVE

To analyze the structure of social representations on the preventive measures to pressure injury of nursing teams.

METHOD

Qualitative research, based on the structural approach of Social Representations. It was conducted with 103 nursing professionals from a specialized hospital, using the Word Association Test. Data were submitted to prototypical analysis, using two analysis techniques of centrality, similarity and double negation.

RESULTS

The evocations "care" and "decubitus" made up the central core of the representation, which was structured based on the imagery dimension of changing position, from which a hierarchy of preventive measures occurs. The term "care" referred to the normative dimension of representation as a responsibility of nursing, and to the practical dimension, as preventive actions with the use of technologies.

CONCLUSION

The image, normative and practice dimensions are part of the representation structure and guide compliance with preventive measures.

An artificial intelligence-enabled smartphone app for real-time pressure injury assessment

The management of chronic wounds in the elderly such as pressure injury (also known as bedsore or pressure ulcer) is increasingly important in an ageing population. Accurate classification of the stage of pressure injury is important for wound care planning. Nonetheless, the expertise required for staging is often not available in a residential care home setting. Artificial-intelligence (AI)-based computer vision techniques have opened up opportunities to harness the inbuilt camera in modern smartphones to support pressure injury staging by nursing home carers. In this paper, we summarise the recent development of smartphone or tablet-based applications for wound assessment. Furthermore, we present a new smartphone application (app) to perform real-time detection and staging classification of pressure injury wounds using a deep learning-based object detection system, YOLOv4. Based on our validation set of 144 photos, our app obtained an overall prediction accuracy of 63.2%. The per-class prediction specificity is generally high (85.1%–100%), but have variable sensitivity: 73.3% (stage 1 vs. others), 37% (stage 2 vs. others), 76.7 (stage 3 vs. others), 70% (stage 4 vs. others), and 55.6% (unstageable vs. others). Using another independent test set, 8 out of 10 images were predicted correctly by the YOLOv4 model. When deployed in a real-life setting with two different ambient brightness levels with three different Android phone models, the prediction accuracy of the 10 test images ranges from 80 to 90%, which highlight the importance of evaluation of mobile health (mHealth) application in a simulated real-life setting. This study details the development and evaluation process and demonstrates the feasibility of applying such a real-time staging app in wound care management.

Braden scale has low reliability in different patients under care in intensive care unit

OBJECTIVE

The aim of this study was to assess the inter-reliability of the Braden scale and its subscales for different patients assisted in the intensive care unit. We hypothesized that the Braden scale has low reliability in different populations.

METHODS

This reliability study involved the Braden scale in intensive care unit of a hospital. A total of 200 patients were admitted to the intensive care unit in four different groups: neurological patients, sepsis, elderly, and adults affected by trauma. The Braden scale is a tool composed of six subscales for patient assessment: sensory perception, humidity, activity, mobility, nutrition, and friction. The total score was also calculated. The Braden scale was applied by two different nurses with an interval of 20-30 min between applications.

RESULTS

For all populations, kappa values considered unsuitable were observed for most categories of the Braden scale, ranging from 0.06-0.25. Only for the total Braden scale score was moderate reliability identified in all groups evaluated, with intraclass correlation coefficient values ranging from 0.48-0.75.

CONCLUSIONS

Braden scale is not a reliable tool to be used in the intensive care unit, and we do not recommend the use of this scale to assess the risk of developing pressure injury.
