Review
AIMS AND OBJECTIVES
To summarize the use of machine learning (ML) for hospital-acquired pressure injury (HAPI) prediction and to systematically assess the performance and construction process of ML models to provide references for establishing high-quality ML predictive models.
BACKGROUND
As an adverse event, HAPI seriously affects patient prognosis and quality of life, and causes unnecessary medical investment. At present, the performance of various scales used to predict HAPIs is still unsatisfactory. As a new statistical tool, ML has been applied to predict HAPIs. However, its performance has varied in different studies; moreover, some deficiencies in the model construction process were observed in each study.
DESIGN
Systematic review.
METHODS
Relevant articles published between 2010-2021 were identified in the PubMed, Web of Science, Scopus, Embase and CINHAL databases. Study selection was performed in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines. The quality of the included articles was assessed using the prediction model risk of bias assessment tool.
RESULTS
Twenty-three studies out of 1793 articles were considered in this systematic review. The sample size of each study ranged from 149-75353; the prevalence of pressure injuries ranged from 0.5%-49.8%. ML showed good performance for HAPI prediction. However, some deficiencies were observed in terms of data management, data pre-processing and model validation.
CONCLUSIONS
ML, as a powerful decision-making assistance tool, is helpful for the prediction of HAPIs. However, existing studies have been insufficient in terms of data management, data pre-processing and model validation. Future studies should address these issues to establish ML models for HAPI prediction that can be widely used in clinical practice.
RELEVANCE TO CLINICAL PRACTICE
This review highlights that ML is helpful in predicting HAPI; however, in the process of data management, data pre-processing and model validation, some deficiencies still need to be addressed. The ultimate goal of integrating ML into HAPI prediction is to develop a practical clinical decision-making tool. A complete and rigorous model construction process should be followed in future studies to develop high-quality ML models that can be applied in clinical practice.

BACKGROUND
Pressure ulcers (PUs) impact on patient's quality of life and are costly for healthcare providers. Heels are a particular concern due to specific risk factors. Relative effectiveness of medical devices, e.g., dressings, off-loading devices, heel cushioning devices, to reduce PU development is unknown.
METHODS
Systematic review of the effectiveness of heel-specific medical devices for the prevention of heel PU (HPU)s. Database searches were performed from inception to June 2021 for RCTs. The primary outcome was incidence of new HPUs. Trials were assessed for risk of bias and data analysed with risk ratios, mean difference or hazard ratios as appropriate.
RESULTS
Fifteen RCTs (4724 participants) were identified. Dressings, as constant low pressure (CLP) devices vs standard care: eight trials (very low quality) showed no-significant difference in effectiveness (RR 0.31, 95%CI 0.10 to 1.01). Off-loading devices vs standard care: three trials (low quality), showed significant reduction in development of Category≥1 HPUs (RR 0.20, 95%CI 0.05 to 0.80) two trials (medium quality), showed significant reduction in development of Category≥2 HPUs (RR 0.08, 95%CI 0.01 to 0.67). Comparisons between off-loading devices: two trials (low quality) showed no clear difference in HPU incidence. In a paediatric post-surgical population, one trial of off-loading device and one of a dressing (CLP device), both versus standard care, showed no clear difference in HPU incidence (RR 0.19 95%CI 0.02 to 1.55 and RR 0.89 95%CI 0.56 to 1.42 respectively).
CONCLUSIONS
Off-loading devices may reduce HPU incidence, from low-quality evidence. There is insufficient evidence to suggest that dressings reduce HPU incidence.

Review
BACKGROUND
There are several possible interventions for managing pressure ulcers (sometimes referred to as pressure injuries), ranging from pressure-relieving measures, such as repositioning, to reconstructive surgery. The surgical approach is usually reserved for recalcitrant wounds (where the healing process has stalled, or the wound is not responding to treatment) or wounds with full-thickness skin loss and exposure of deeper structures such as muscle fascia or bone. Reconstructive surgery commonly involves wound debridement followed by filling the wound with new tissue. Whilst this is an accepted means of ulcer management, the benefits and harms of different surgical approaches, compared with each other or with non-surgical treatments, are unclear. This is an update of a Cochrane Review published in 2016.
OBJECTIVES
To assess the effects of different types of reconstructive surgery for treating pressure ulcers (category/stage II or above), compared with no surgery or alternative reconstructive surgical approaches, in any care setting.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search date was January 2022.
SELECTION CRITERIA
Published or unpublished randomised controlled trials (RCTs) that assessed reconstructive surgery in the treatment of pressure ulcers.
DATA COLLECTION AND ANALYSIS
Two review authors independently selected the studies, extracted study data, assessed the risk of bias and undertook GRADE assessments. We would have involved a third review author in case of disagreement.
MAIN RESULTS
We identified one RCT conducted in a hospital setting in the USA. It enrolled 20 participants aged between 20 and 70 years with stage IV ischial or sacral pressure ulcers (involving full-thickness skin and tissue loss). The study compared two reconstructive techniques for stage IV pressure ulcers: conventional flap surgery and cone of pressure flap surgery, in which a large portion of the flap tip is de-epithelialised and deeply inset to obliterate dead space. There were no clear data for any of our outcomes, although we extracted some information on complete wound healing, wound dehiscence, pressure ulcer recurrence and wound infection. We graded the evidence for these outcomes as very low-certainty. The study provided no data for any other outcomes.
AUTHORS' CONCLUSIONS
Currently there is very little randomised evidence on the role of reconstructive surgery in pressure ulcer management, although it is considered a priority area. More rigorous and robust research is needed to explore this intervention.

Meta-Analysis
BACKGROUND
Nasal pressure injury is a serious problem during nasotracheal intubation. We performed this systematic review and meta-analysis to determine whether use of a nasal protection strategy (a protective dressing or a modified fixation method for the tracheal tube) reduces the incidence of nasal pressure injury during nasotracheal intubation.
METHODS
Literature searches were performed using three electronic databases. Data from each of the eligible trials were combined, and calculations were made using DerSimonian and Laird random effects models. The pooled effect estimates for nasal pressure injury were evaluated using the relative risk and 95% confidence interval, the Cochrane Q statistic, and the I2 statistic. We also performed trial sequential analysis (TSA) to assess sensitivity to prevent type I error. We separated patients into subgroups to analyze the incidence of nasal pressure injury according to whether a protective dressing or a modified fixation method for the tracheal tube was used.
RESULTS
The literature search yielded five eligible trials. Meta-analysis of these trials showed that a nasal protection strategy significantly reduced the incidence of nasal pressure injury during nasotracheal intubation (relative risk (RR) 0.34; 95% confidence interval (CI) 0.21-0.56; P < .0001; Cochrane's Q = 5.86, I2 = 32%). The TSA boundary for futility could not be calculated because of an insufficient sample size. In subgroup analysis, both methods significantly reduced the incidence of nasal pressure injury during nasotracheal intubation.
CONCLUSIONS
The findings of this meta-analysis suggest that a nasal protection strategy significantly reduces the incidence of nasal pressure injury during nasotracheal intubation. During nasotracheal intubation, the use of a protective dressing or modified fixation method for the tracheal tube can prevent to the incidence of nasal pressure injuries. However, the number of samples in our meta-analysis was too small for TSA and further studies are required.

Meta-Analysis
BACKGROUND
Pressure ulcers (PUs) are an indicator of the quality of nursing care and nurses can prevent PUs well if they have sufficient knowledge. Numerous studies in this field have reported different results. The aim of this study was to estimate the pooled score of nurses' knowledge about PU prevention based on the Pressure Ulcer Knowledge Assessment Tool (PUKAT).
METHODS
In this systematic review and meta-analysis, databases including Web of Science, ScienceDirect, PubMed, and Scopus were searched. All studies published in English between 2011 and 2022 that reported the status of nurses' knowledge of PU prevention based on PUKAT were included in the analysis. Based on heterogeneity between the studies, the data were analyzed using a random effects model.
RESULTS
The pooled scores of PU prevention knowledge in nurses and nursing students were (51.5%; 95% CI: 45.8-57.2%) and (48.9%; 95% CI: 42.5-55.2%), respectively. As the age of the participants increased, the pooled score of pressure ulcer prevention knowledge increased significantly ( = 0.028). The publication bias was not significant. The highest and lowest knowledge scores in nurses and nursing students were related to the fourth dimension (nutrition) and the fifth dimension (preventive measures to reduce the amount of pressure/shear), respectively.
CONCLUSION
Knowledge of nurses and nursing students about PU prevention is insufficient. Providing regular training to nurses and including the principles of PU prevention in the curriculum of nursing students to improve their knowledge seems necessary.

Review
Wounds with delayed or impaired healing represent a considerable challenge in medical practice. These patients develop a sustained hypermetabolic and catabolic state, directly impacting the wound healing process. The use of oxandrolone has been studied to control this metabolic imbalance and protect lean body mass as a beneficial resource in wound healing. This systematic review aims to analyze previously conducted randomized controlled trials to evaluate the evidence of the applicability of oxandrolone therapy. We compared its use in adult patients with burns and adult patients with pressure ulcers in terms of wound healing and healing time of the skin graft donor site in days. The digital searches were done from March 23-28, 2022, within the databases: Google Scholar, PubMed/MEDLINE, and EBSCO (Elton B. Stephens Company). Data from six studies were analyzed and included in this review. Analysis of the available data demonstrated a significant advantage in skin healing using oxandrolone in adult burn patients as an adjunct. For adult patients with pressure ulcers, the drug showed no benefit on wound healing and skin graft site healing. Importantly, we found only one study evaluating the use of oxandrolone in patients with decubitus ulcers that met our eligibility criteria, and the certainty of the evidence was low. Thus, further prospective randomized studies with larger samples and standard wound care protocols are needed to produce more solid results, allowing more definitive conclusions to be made on this theme.

Meta-Analysis Review
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 I 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.

Meta-Analysis Review
BACKGROUND
Pressure injury is a common complication after a spinal cord injury. Long-term multidisciplinary follow-up is difficult after such patients have been discharged. Telemedicine promises to provide convenient and effective support for the prevention and treatment of pressure injury, but previous attempts to demonstrate that have produced inconsistent results.
OBJECTIVE
The aim of this study is to evaluate the effectiveness of telemedicine in preventing and treating pressure injury among community-dwelling patients with spinal cord injury, and determine which telemedicine form is more effective.
METHODS
This systematic review was performed according to the PRISMA-NMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Network Meta-Analysis) standards. Ten databases were searched to identify randomized controlled trials and quasi-experimental studies related to the effectiveness of telemedicine intervention in patients with spinal cord injury. Two researchers worked independently and blindly selected studies, extracted data, and assessed the risk of bias. The results were described as relative risk (RR) and weighted mean difference and 95% CI.
RESULTS
The 35 studies comprised 25 randomized controlled trials and 10 quasi-experimental studies involving 3131 patients. The results showed that telemedicine can significantly (P<.05) reduce the incidence of pressure injury (RR 0.24, 95% CI 0.14-0.41; P<.05; I=0%), promote faster healing (RR 0.73, 95% CI 0.62-0.85; P<.05; I=0%), and yield lower scores on the pressure ulcer scale of healing (weighted mean difference=-1.98, 95% CI -3.51 to -0.46; P<.05; I=0%). Cumulative ranking estimates showed that combining telemedicine with conventional intervention (93.5%) was the most effective approach.
CONCLUSIONS
Telemedicine is a feasible way to prevent pressure injury among patients with spinal cord injuries. It can decrease the incidence and severity of pressure injury and accelerate patients' healing without imposing economic burden. It is best used in tandem with other, more conventional interventions. Due to the limited quality and quantity of included studies, large-scale and well-designed randomized controlled trials are warranted.

Review
This systematic review aimed to examine skin hydration and determine if this biophysical parameter can predict pressure ulcer development in at risk adults. A literature search was conducted in March 2022, using PubMed, CINAHL, SCOPUS, Cochrane, and EMBASE databases. A total of 1727 records were returned, with 9 studies satisfying the inclusion criteria. Data were extracted using a pre-designed extraction tool and a narrative synthesis of the data was undertaken. The methodological quality of the included articles was assessed using the evidence-based librarianship checklist. Included studies were published between 1997 and 2021, with most using a prospective cohort design (88.9%, n = 8). The mean sample size was 74 participants (SD = 38.6; median 71). All studies measured skin hydration objectively, with 55.6% (n = 5) using the Corneometer® CM825 and 33.3% (n = 3) of studies reported a statistically significant association between skin hydration and pressure ulcer development. The mean evidence-based librarianship percentage was 66.6% (SD: 20.7%), however, only 33.3% (n = 3) of studies scored ≥75%, indicating validity. The quality of included studies, methodology variation, and reported results has reduced the homogeneity of outcomes. This review highlights the requirement for future research evidence to ascertain the role of skin hydration in pressure ulcer development.

Review
The present study sought to explore the impact of movement monitoring devices on risk prediction and prevention of pressure ulcers (PU) among adults. Using systematic review methodology, we included original research studies using a prospective design, written in English, assessing adult patients' movement in bed, using a movement monitoring device. The search was conducted in March 2021, using PubMed, CINAHL, Scopus, Cochrane, and EMBASE databases, and returned 1537 records, of which 25 met the inclusion criteria. Data were extracted using a pre-designed extraction tool and quality appraisal was undertaken using the evidence-based librarianship (EBL). In total, 19 different movement monitoring devices were used in the studies, using a range of physical sensing principles. The studies focused on quantifying the number and types of movements. In four studies the authors compared the monitoring system with PU risk assessment tools, with a variety of high and low correlations observed. Four studies compared the relationship between movement magnitude and frequency and the development of PUs, with variability in results also identified. Two of these studies showed, as expected, that those who made less movements developed more PU; however, the two studies also unexpectedly found that PUs occurred in both low movers and high movers. In the final two studies, the authors focused on the concordance with recommended repositioning based on the results of the monitoring device. Overall, concordance with repositioning increased with the use of a monitoring device. The synthesis of the literature surrounding bed monitoring technologies for PU risk prediction showed that a range of physical sensors can be used to detect the frequency of movement. Clinical studies showed some correlation between parameters of movement and PU risk/incidence, although the heterogeneity of approaches limits generalisable recommendations.
