Prevalence and incidence of pressure ulcers in Japanese long-term-care hospitals

Improving machine learning algorithm for risk of early pressure injury prediction in admission patients using probability feature aggregation

Objective

Pressure injuries (PIs) pose a significant concern in hospital care, necessitating early and accurate prediction to mitigate adverse outcomes.

Methods

The proposed approach receives multiple patients records, selects key features of discrete numerical based on their relevance to PIs, and trains a random forest (RF) machine learning (ML) algorithm to build a predictive model. Pairs of significant categorical features with high contributions to the prediction results are grouped, and the PI risk probability for each group is calculated. High-risk group probabilities are then added as new features to the original feature subset, generating a new feature subset to replace the original one, which is then used to retrain the RF model.

Results

The proposed method achieved an accuracy of 83.44%, sensitivity of 84.59%, specificity of 83.42%, and an area under the curve of 0.84.

Conclusion

The ML-based approach, coupled with feature aggregation, enhances predictive performance, aiding clinical teams in understanding crucial features and the model's decision-making process.

Interventions to promote the implementation of pressure injury prevention measures in nursing homes: A scoping review

AIMS

To identify studies and the content of the interventions that have facilitated the implementation of pressure injury (PI) prevention measures in nursing home settings.

DESIGN AND METHOD

A scoping review methodology was employed. The author has carried out the following steps successively: Identified this scoping review's questions, retrieved potentially relevant studies, selected relevant studies, charted the data, summarised the results, and consulted with stakeholders from nursing homes in China.

DATA SOURCES

Six electronic databases and three resources of grey literature-PubMed, CINAHL, Web of Science Core Collection, Embase, Cochrane Central Register of Controlled Trials, Psych INFO, Open Grey, MedNar, ProQuest Dissertations, and Theses Full Texts were searched from January 2002 through May 2022.

RESULTS

Forty articles were included, among which the primary interventions were quality improvement, training and education, evidence-based practice, device-assisted PI prophylaxis, nursing protocols, and clinical decision support systems. Twenty-three outcome indicators were summarised in 40 articles, which included 10 outcome indicators, seven process indicators, and six structural indicators. Furthermore, only five articles reported barriers in the process of implementing interventions.

CONCLUSION

The common interventions to promote the implementation of PI prevention measures in nursing homes are quality improvement, training, and education. Relatively limited research has been conducted on evidence-based practice, clinical decision support systems, device-assisted PI prophylaxis, and nursing protocols. In addition, there is a paucity of studies examining the impediments to implementing these measures and devising targeted solutions. Therefore, it is recommended that future studies include analysis and reporting of barriers and facilitators as part of the article to improve the sustainability of the intervention.

IMPACT

This article reminds nursing home managers that they should realise the importance of implementation strategies between the best evidence of PI prevention and clinical practice. Also, this review provides the types, contents, and outcome indicators of these strategies for managers of nursing homes to consider what types of interventions to implement in their organisations.

TRIAL AND PROTOCOL REGISTRATION

The protocol of this scoping review was published as an open-access article in June 2022 (Yang et al., 2022).

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

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

Dermatological Diseases in Palliative Care Patients in a University Hospital: A Prospective Study

OBJECTIVE

Patients receiving palliative care are more prone to dermatological disease. The aim of our study was to determine the frequency of dermatological diseases and associated factors in patients receiving palliative care support.

METHODS

This prospective observational study included inpatients in the palliative care unit of our university hospital in Erzurum/TURKEY. The patients were evaluated by the same dermatologist within the first 48 h of admission and 3 days a week during follow-up. Demographic data, reasons for admission to the palliative care unit, and skin lesions at the time of admission and during follow-up were recorded.

RESULTS

The median age of the 259 patients included in the study was 77.0 years (min- max, 19-108) and 54.4% were women. Dermatological disease was detected in 246 patients (96.1%) at admission to the palliative care unit and in 185 patients (71.4%) patients during follow-up. The most common dermatological disease at admission was dry skin (n  =  175, 67.6%), which was also the most common cause of pruritis (n  =  29, 11.2%). The most common skin infection was dermatophytosis (n  =  57, 22.0%) and the most common type of dermatitis was contact dermatitis (n  =  17, 6.6%). Nearly all tumors were benign (n  =  32, 12.4%) and most chronic wounds were pressure ulcers (n  =  96, 37.1%). During hospital follow-up, the most frequent dermatitis was contact dermatitis (n  =  44, 17.0%), the most frequent skin infection was candidiasis (n  =  25, 9.7%), the most common chronic wound was pressure ulcers (n  =  25, 9.7%), the most common dermatological disease was urticaria (n  =  14, 5.4%), and all cases of pruritus were associated with dry skin (n  =  8, 3.1%).

CONCLUSIONS

The frequency of dermatological findings is high among patients receiving palliative care. Therefore, dermatologists should be included in multidisciplinary palliative care teams and evaluate palliative care patients early and regularly.

A multilocus sequence typing method of Staphylococcus aureus DNAs in a sample from human skin

The skin and mucous membranes are the primary sites of Staphylococcus aureus colonization, particularly those of health care personnel and patients in long-term care centers. We found that S. aureus colonized with a higher abundance ratio on skins which had recovered from pressure injury (PI) than on normal skins in our earlier research on the skin microbiota of bedridden patients. Multilocus sequence typing (MLST) is a useful tool for typing S. aureus isolated from clinical specimens. However, the MLST approach cannot be used in microbiota DNA owing to the contamination from other bacteria species. In this study, we developed a multiplex-nested PCR method to determine S. aureus MLST in samples collected from human skins. The seven pairs of forward and reverse primers were designed in the upstream and downstream regions, which were conserved specifically in S. aureus. The first amplifications of the seven pairs were conducted in a multiplex assay. The samples were diluted and applied to conventional PCR for MLST. We confirmed that the method amplified the seven allele sequences of S. aureus specifically in the presence of untargeted DNAs from human and other skin commensal bacteria. Using this assay, we succeeded in typing sequence types (STs) of S. aureus in the DNA samples derived from the skins healed from PI. Peaks obtained by Sanger sequencing showed that each sample contained one ST, which were mainly categorized into clonal complex 1 (CC1) or CC5. We propose that this culture-free approach may be used in detecting S. aureus in clinical specimens without isolation.

Social Engagement and Distress Among Home Care Recipients During the COVID-19 Pandemic in Ontario, Canada: A Retrospective Cohort Study

OBJECTIVES

To examine factors associated with distressing social decline and withdrawal during the COVID-19 pandemic for home care recipients.

DESIGN

Retrospective cohort.

SETTING AND PARTICIPANTS

Home care recipients age 18 years or older in Ontario, Canada without severe cognitive impairment with an assessment and follow-up between September 1, 2018 and August 31, 2020.

METHODS

Data were collected using the interRAI home care. Outcomes of interest were distressing decline in social participation and social withdrawal. Independent variables were entered into multivariable longitudinal generalized estimating equations. Interaction terms with the pandemic were tested. Those significant at P < .01 were retained in final models and reported as odds ratios (ORs), 95% confidence intervals (CIs).

RESULTS

We compared 26,492 and 19,126 home care recipients before and during the pandemic, respectively. The pandemic was associated with greater odds of experiencing distressing social decline (OR 1.28, 95% CI 1.22‒1.34) and withdrawal (OR 1.09, 95% CI 1.04‒1.15). Living alone (OR 1.13, 95% CI 1.05‒1.22), frailty (OR 3.21, 95% CI 2.76‒3.73), health instability (OR 2.22, 95% CI 2.02‒2.44), and depression (OR 2.14, 95% CI 2.01‒2.29) increased the odds of distressing social decline. Older age (OR 0.71, 95% CI 0.65‒0.77), functional impairment (OR 0.58, 95% CI 0.51‒0.67), and receiving caregiving (OR 0.73, 95% CI 0.67‒0.79) decreased the odds. Home care recipients with mild/moderate dementia were less likely to experience distressing social decline during the pandemic. Those who lived alone were more likely. Frailty (OR 9.49, 95% CI 7.69‒11.71) and depression (OR 2.76, 95% CI 2.55‒3.00) increased the odds of social withdrawal. Functional impairment (OR 0.32, 95% CI 0.27‒0.39), congestive heart failure (OR 0.77, 95% CI 0.70‒0.84), and receiving caregiving (OR 0.50, 95% CI 0.46‒0.55) decreased the odds. Home care recipients age 18‒64 years and older than 75 years were less likely to experience social withdrawal during the pandemic.

CONCLUSIONS AND IMPLICATIONS

Social support interventions should focus on supporting those living alone, with frailty, health instability, or depression.

Interventions to promote the implementation of pressure injuries prevention measures in nursing homes: a scoping review protocol

INTRODUCTION

Currently, various guidelines and documents on the prevention of pressure injuries have been published, but there are many serious lags in the actual practice in nursing homes. So some interventions are required to promote the implementation of normative practices. There was a review of preventive interventions for pressure injuries in long-term care facilities, but there is no systematic review of how to promote the implementation of preventive measures. This review aims to summarise interventions that promote the implementation of pressure injuries prevention measures in nursing homes, explore the research scope and gaps in this field and provide evidence and striving direction for global nursing homes to improve existing preventive behaviours.

METHODS AND ANALYSIS

This scoping review will combine the Arksey and O'Malley framework with further clarification and advice of the scoping review by Levac et al as methodological guidance. Systematic retrieval of relevant literature databases, grey literature and references included studies will be conducted. Two reviewers will screen titles and abstracts independently, and then screen the full text of potentially relevant articles to determine final inclusion. After that, two reviewers will extract data based on a predesigned data extraction table independently. Inductive analysis and narrative analysis will be used to collate, summarise and report the results. Finally, managers of nursing homes in China will be consulted for additional information and their viewpoints on the research findings.

ETHICS AND DISSEMINATION

Since the scoping review is a secondary analysis of the literature, there is no need to apply for ethical approval. Our goal is to share the results with key stakeholders to help them find the direction of effort and improve clinical practice. Therefore, dissemination plans include publication in international journals and sharing it at conferences to inform more healthcare workers about the scope and gaps of the studies.

Effect of a wound healing protocol on patients with stage III and IV pressure ulcers: a preliminary observational study

Objective:

To evaluate the influence of a wound healing protocol for stage III and IV pressure ulcers (PUs), and to determine the predictive power of specific sociodemographic and clinical characteristics on wound healing and infection.

Method:

This longitudinal study included participants with stage III and IV PUs who were recruited from 10 acute care settings of an Italian university hospital, and who were managed with a protocol inspired by the TIMECare model. Data were collected between October 2018 and March 2019. The National Pressure Ulcer Advisory Panel Staging System was used to stage the PUs. Wound healing was assessed with the Pressure Ulcer Scale for Healing (PUSH). Nutritional status was assessed with the Mini Nutritional Assessment Index. Data collection took place at admission and every seven days thereafter—a total of six times before discharge. The outcome and predictors of wound healing were assessed with Student's paired t-tests and multiple linear regressions, respectively.

Results:

Patients (n=126) were almost equally split between male and female, with a mean age of 78.17 years and who were all retired. Stage III and IV PUs were most prevalent at the sacrum (65.5% and 73.2%, respectively). PUSH wound healing scores improved significantly after six weeks in both stage III and IV PUs (p<0.001). Nutritional status was predictive of wound healing (R2=0.12).

Conclusion:

Our results showed that a good nutritional status and a protocol inspired by the TIMECare model were associated with wound healing improvements in stage III and IV PUs. We recommend this protocol in older patients with stage III and IV PUs.

Interspecies Regulation Between Staphylococcus caprae and Staphylococcus aureus Colonized on Healed Skin After Injury

Staphylococcus spp. colonize commensally on the human skin. Some commensal coagulase-negative staphylococci and Staphylococcus aureus are also involved in nosocomial infections. Bacteria were collected from skin healed from pressure injury (PI). After the collection time points, some patients suffered from recurrent PI (RPI). This study analyzed the characteristics of Staphylococcus spp. on healed skin before recurrence between healed skin that suffered from RPI within 6 weeks (RPI group) and healed skin that did not suffer within the duration (non-RPI group) by Staphylococcus spp.-specific sequencing. Of the seven patients in the RPI group, two were dominated by S. aureus and four by Staphylococcus caprae, coagulase-negative human commensal staphylococci in the RPI group. Using mouse models, both S. caprae and S. aureus, but not Staphylococcus epidermidis, colonized on skin healed from injury at significantly higher rates than normal skin. Although subcutaneous injection of S. caprae did not induce lesion formation, the bacterium exhibited high hemolytic activity on human red blood cells. Lesion formation by subcutaneous injection of S. aureus was significantly suppressed in the presence of S. caprae. The hemolytic activity of rabbit blood cells of S. aureus was suppressed by S. caprae, whereas the hemolytic activity of S. caprae was dramatically suppressed by S. aureus. Data indicated that each of the two Staphylococcus spp. suppresses the pathogenicity of the other and that the imbalance between the two is associated with RPI.

Increased temperature at the healed area detected by thermography predicts recurrent pressure ulcers

Preventing recurrent pressure ulcers is an important challenge in healthcare. One of the reasons for the high rate of recurrent pressure ulcers is the lack of assessment methods for their early detection. Therefore, this study aimed to determine the thermographic characteristics of the healed area and to consider the predictive validity of thermographic images for recurrent pressure ulcers within a 2-week period. This observational study was conducted at a long-term care facility in Japan between July 2017 and February 2019 among patients whose pressure ulcers had healed. Thermographic images of the healed area were recorded once a week until recurrence or until the end of the study. We enrolled 30 participants, among whom 8 developed recurrent pressure ulcers. The generalised estimation equation revealed that the thermographic finding of increased temperature at the healed area compared to that of the surrounding skin was significantly associated with recurrent pressure ulcers (odds ratio: 101.13, 95% confidence interval: 3.60-2840.77, p = .007); the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio for recurrent pressure ulcers within 2 weeks were 0.80, 0.94, 0.62, 0.97, 12.9 and 0.2, respectively. Our thermographic findings revealed that the temperature of the healed area was higher than that of the surrounding skin; this could be a useful predictor of pressure ulcer recurrence within 2 weeks, even in the absence of macroscopic changes.

A narrative review of the epidemiology and economics of chronic wounds

Chronic wounds have a debilitating effect on the quality of life of many individuals, and the large economic impact on health system budgets warrants greater attention in policy making and condition management than is currently evident. The aim of this narrative review is to summarize the nature and extent of the chronic wound problem that confronts health systems across the world. The first section is used to highlight the underlying epidemiology relating to chronic wounds, while the second explores the economic costs associated with them and the relative efficiency of measures designed to manage them.

Using Machine Learning Technologies in Pressure Injury Management: Systematic Review

Background

Pressure injury (PI) is a common and preventable problem, yet it is a challenge for at least two reasons. First, the nurse shortage is a worldwide phenomenon. Second, the majority of nurses have insufficient PI-related knowledge. Machine learning (ML) technologies can contribute to lessening the burden on medical staff by improving the prognosis and diagnostic accuracy of PI. To the best of our knowledge, there is no existing systematic review that evaluates how the current ML technologies are being used in PI management.

Objective

The objective of this review was to synthesize and evaluate the literature regarding the use of ML technologies in PI management, and identify their strengths and weaknesses, as well as to identify improvement opportunities for future research and practice.

Methods

We conducted an extensive search on PubMed, EMBASE, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Library, China National Knowledge Infrastructure (CNKI), the Wanfang database, the VIP database, and the China Biomedical Literature Database (CBM) to identify relevant articles. Searches were performed in June 2020. Two independent investigators conducted study selection, data extraction, and quality appraisal. Risk of bias was assessed using the Prediction model Risk Of Bias ASsessment Tool (PROBAST).

Results

A total of 32 articles met the inclusion criteria. Twelve of those articles (38%) reported using ML technologies to develop predictive models to identify risk factors, 11 (34%) reported using them in posture detection and recognition, and 9 (28%) reported using them in image analysis for tissue classification and measurement of PI wounds. These articles presented various algorithms and measured outcomes. The overall risk of bias was judged as high.

Conclusions

There is an array of emerging ML technologies being used in PI management, and their results in the laboratory show great promise. Future research should apply these technologies on a large scale with clinical data to further verify and improve their effectiveness, as well as to improve the methodological quality.

Patient and lay carer education for preventing pressure ulceration in at-risk populations

BACKGROUND

Pressure ulcers (PUs) are injuries to the skin and underlying tissues that occur most commonly over bony prominences, such as the hips and heels as a result of pressure and shear forces. PUs cause pain, discomfort, longer hospital stays, and decreased quality of life. They are also very costly to treat and consume substantial parts of healthcare budgets. PUs are largely preventable, and education targeted at patients and their carers is considered important.

OBJECTIVES

To assess the effects of patient and/or lay carer education on preventing pressure ulceration in at-risk people, in any care setting.

SEARCH METHODS

In June 2019 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase; Ovid PsycINFO and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies.  There were no restrictions with respect to language, date of publication or study setting.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that recruited people of any age at risk of pressure ulceration, and RCTs that recruited people who informally care for someone at risk of pressure ulceration.

DATA COLLECTION AND ANALYSIS

Two review authors independently performed study selection, data extraction, 'Risk of bias' assessment, and GRADE assessment of the certainty of the evidence.

MAIN RESULTS

We included 10 studies with 11 publications (2261 participants analysed). Seven targeted their intervention at people at risk of ulceration and measured outcomes on these at risk people; two targeted those at risk and their family carers and measured outcomes on the at risk people cared for by their families; and one targeted lay carers only and measured outcomes on the at risk people they cared for. There were two main types of interventions: the provision of information on prevention of pressure ulcers, and the use of different types of education programmes. Provision of information on the prevention of pressure ulcers Three studies (237 participants) reported data for this comparison: two provided information directly to those at risk and their carers, and the third provided information to lay carers. As data could not be pooled we present individual study data. The evidence for primary outcomes is of very low certainty (downgraded twice for study limitations and twice for imprecision). We are uncertain whether the combined use of a self-instruction manual and one-to-one patient training and counselling versus a self-instruction manual alone reduces the proportion of at risk people developing a new PU (risk ratio (RR) 0.40, 95% confidence interval (CI) 0.14 to 1.18), or whether carer self-instruction and one-to-one counselling versus self-instruction alone reduces the proportion of at risk people developing a new PU (RR 2.05, 95% CI 0.19 to 21.70). We are uncertain whether the use of home-based training, compared with routine ward-based training, reduces the proportion of at risk people developing a new PU (RR 0.53, 95% CI 0.27 to 1.02). One study explored the secondary outcome patient knowledge of pressure ulcer prevention; however, as usable data were not provided, we were unable to carry out further analysis, and no effect estimate could be calculated. Educational programmes on the prevention of pressure ulcers Seven studies (2024 participants analysed) provided data for this comparison. In all studies the intervention was aimed at people at risk of ulceration. Risk of pressure ulceration One secondary report of an included study reported the primary outcome as time to PU development or occurrence and three studies and one secondary report of an included study reported this as the proportion of at risk people developing a new PU. One study reported the secondary outcome grade of PU and five studies and one secondary report of an included study reported on patient knowledge. There is low certainty evidence of there being no clear difference in the proportion of participants developing a new PU between use of a pressure ulcer prevention care bundle (PUPCB) and standard care: HR 0.58, 95% CI 0.25 to 1.33 (downgraded twice for imprecision). One secondary report of an included study explored whether individualised PU education and monthly structured telephone follow-up reduces the mean time to PU occurrence. Not all participants in this study developed a pressure ulcer, therefore the mean time to pressure ulcer occurrence could not be calculated from the data. We are uncertain whether the following three interventions reduce the proportion of at risk people developing a new PU as we assessed the certainty of evidence as very low: individualised PU education and monthly structured telephone follow-up (RR 0.55, 95% CI 0.23 to 1.30), education delivery (RR 3.57, 95% CI 0.78 to 16.38), (downgraded twice for risk of bias and twice for imprecision); and computerised feedback and one-to-one consultations (no clear data provided), (downgraded twice for risk of bias and once for indirectness). Grade of pressure ulcer There is low certainty evidence that use of a PU prevention care bundle may make no difference to the severity of new PU development when compared with standard care. Patient knowledge We are uncertain whether the following interventions improve patient knowledge: enhanced educational intervention and structured follow-up (mean difference (MD) 9.86, 95% CI 1.55 to 18.17); multi component motivational interviewing/self-management with a multi component education intervention (no clear data provided); Spinal Cord Injury Navigator programme (no clear data provided); individualised PU education and monthly structured telephone follow-up (no clear data provided); computerised feedback (no clear data provided), structured, patient-centric PU prevention education event (MD 30.15, 95% CI 23.56 to 36.74). We assessed the certainty of the evidence for this outcome as low or very low (downgraded for risk of bias, imprecision, or indirectness).

AUTHORS' CONCLUSIONS

We are uncertain whether educational interventions make any difference to the number of new PUs that develop, or to patient knowledge based on evidence from the 10 included studies, which we assessed as of low or very low certainty due to problems with risk of bias, serious imprecision and indirectness. The low certainty of evidence means that additional research is required to confirm these results.

Convergent Validity of Three Pressure Injury Risk Assessment Scales: Comparing the PPRA-Home (Pressure Injury Primary Risk Assessment Scale for Home Care) to Two Traditional Scales

Purpose

The Pressure Injury Primary Risk Assessment Scale for Home Care (PPRA-Home) was developed to predict pressure injury risk in geriatric individuals requiring long-term care in home settings. This study aimed to compare the convergent validity of the PPRA-Home to that of the two other standardized pressure injury prevention scales: the Braden and Ohura-Hotta (OH) scales.

Methods

A multicenter, cross-sectional study was conducted with 34 home-based geriatric support service providers located in five Japanese districts. The study included 69 participants (30 had a pressure injury and 39 did not) who were at classified at care levels of 1 through 5 under Japan’s long-term care insurance system. Care managers served as assessors for the PPRA-Home, while physicians or certified expert nurses served as assessors for the Braden and OH scales. Convergent validity was investigated by examining correlation coefficients between total scores on the PPRA-Home and the other two scales. Receiver operating curve analysis was used to quantify each scale’s accuracy for the two groups: those with and without a pressure injury.

Results

The PPRA-Home was found to be negatively correlated with the Braden scale (r=−0.79, p<0.05), and positively correlated with the OH scale (r=0.58, p<0.05). The area under the curve (AUC) for the PPRA-Home, Braden scale, and OH scale were 0.737, 0.814, and 0.794, respectively. A PPRA-Home cutoff score of 4 had a sensitivity of 63.3% and specificity of 81.6%.

Conclusion

The AUC for the PPRA-Home as scored by care managers was similar to those of the Braden and OH scales as scored by physicians or expert nurses. More research on the PPRA-Home’s content and predictive validity is required.

Inter-Rater Reliability of a Pressure Injury Risk Assessment Scale for Home Care: A Multicenter Cross-Sectional Study

Purpose

The aim of the current study was to assess the inter-rater reliability and agreement of the Pressure Injury Primary Risk Assessment Scale for Home Care (PPRA-Home), a risk assessment scale recently developed for Japan-specific social welfare professionals called care managers, to predict pressure injury risk in geriatric individuals who require long-term home care needs.

Methods

A multicenter cross-sectional study was conducted at 30 home-based geriatric support services facilities located at four local districts in Japan. Eligible participants were individuals who needed partial or full assistance for daily living under Japan’s long-term care insurance system (care levels 1–5). The degree of agreement and kappa coefficient were calculated for each item and the total score, after which inter-rater reliability was determined. The effect of the participant’s care level on reliability was also evaluated as secondary analysis.

Results

A total of 96 participants were assessed by 83 care managers (two assessors scored each participant). The degree of agreement and calculated kappa coefficient of the PPRA-Home total score were 59% and 0.72, respectively, with the inter-rater reliability for the total score determined to be “Substantial”. Our subgroup analysis showed that the inter-rater reliability differed according to the participant’s care level. Accordingly, the kappa coefficient for the total score was lower in subgroup “care level 1–3” than in subgroup “care level 4–5” (0.51 and 0.76, respectively).

Conclusion

Our result showed that the PPRA-Home has substantial inter-rater reliability for evaluation of risks of pressure injury development at home care. However, some research focusing on intra-later reliability and validity of the PPRA-Home with adequate sample sizes are required to provide categorical conclusions on whether it can be used for the risk assessment scale in actual clinical settings.

Prevalence, incidence and associated factors of pressure injuries in hospices: A multicentre prospective longitudinal study

BACKGROUND

Patients in palliative care are the population cohort that most frequently develop pressure injuries, severely impacting their quality of life. Data from prospective studies on the prevalence and incidence of pressure injuries in hospices are lacking.

AIM

To describe the point prevalence and cumulative incidence of pressure injuries in patients admitted to residential hospices, and to analyze their predictive factors over time.

DESIGN

Multicentre prospective longitudinal observational study.

SETTING/PARTICIPANTS

Adult patients (n = 992) enrolled in 13 Italian residential hospices, with a minimum sample of 280 for each macro-region (North, center, South/Islands).

METHODS

Assessments including the Karnofsky Performance Status, Braden, Edmonton Symptom Assessment System Revised scales and pressure injury staging according to National Pressure Ulcer Advisory Panel were conducted at least every four days, from admission to patients' death/discharge.

RESULTS

The 7,967 observations recorded provided prevalence and incidence rates of 34.1% and 26.5%, respectively. The logistic regression model showed non-cancer disease (OR = 2.39, 95%CI = 1.65-3.47), age >80 (OR = 2.01, 95%CI = 1.49-2.71), Braden score 'at risk' (OR = 1.92, 95%CI = 1.17-3.14), urinary catheter (OR = 1.96, 95%CI = 1.40-2.75), drowsiness (OR = 1.41, 95%CI = 1.02-1.95) and artificial nutrition (OR = 1.47, 95%CI = 1.01-2.14) as the variables associated with pressure injury at admission. The generalized estimating equations models, built on the timeframes for observation groups, revealed male gender (OR = 1.68, 95%CI = 1.01-2.79) and Braden score 'at risk' (OR = 4.45, 95%CI = 1.74-11.34) as predictive factors of a new pressure injury developed up to three weeks before a patient's death, while in the last ten days of life these predictors were replaced by diagnosis of cancer (OR = 1.80, 95%CI = 1.11-2.91), worsening pain (OR = 1.65, 95%CI = 1.10-2.49), drowsiness (OR = 1.79, 95%CI = 1.25-2.57) and dyspnea (OR = 1.48, 95%CI = 1.01-2.18).

CONCLUSIONS

The high incidence and prevalence of pressure injuries confirm the importance of palliative care nurses continuously focusing on prevention and management strategies. In the last three weeks of a patient's life, the predictive power of the Braden scale for a new pressure injury is not confirmed, throwing doubt on the effectiveness of aimed interventions at modifying risk factors. Along the different disease trajectories, pressure injuries developed during the instability/worsening phases of illness, occurring before hospice admission for non-cancer patients and in the end-of-life phase for cancer patients. Despite continuous provision of appropriate interventions, most of the new pressure injuries were detected during the last ten days of a patient's' life and assessed as 'unavoidable'. These results are crucial to guiding palliative care nursing plans during the different phases of illness, and to predicting care needs, possible management strategies ('wound management' vs. 'wound palliation'), and resource utilization.

Incidence of hospital-acquired pressure injury: A cohort study of adults admitted to public and private hospitals in Sao Paulo, Brazil

This study aimed to estimate the incidence of hospital-acquired pressure injury (PI) and its risk factors in inpatient and intensive care units of five hospitals (two public and three private) in the city of Sao Paulo, Brazil. A 6-month follow-up prospective cohort study (n = 1937) was conducted from April to September 2013. Baseline and follow-up measurements included demographic and care information, as well as risk assessments for both undernutrition (NRS-2002) and PI (Braden scale). Poisson regression with robust variance was used for data analysis. A total of 633 patients (32.60%) showed risk for PI. The incidence rate of PI was of 5.9% (9.9% in public hospitals vs 4.1% in private hospitals) and was higher in intensive care units, compared to inpatient care units (10% vs 5.7%, respectively). Risk for PI increased with age (RR = 1.05; 95% CI 1.04-1.07); was higher in in public hospitals, compared to private hospitals (RR = 4.39; 95% CI 2.92-6.61); in patients admitted for non-surgical reasons compared to those admitted for surgical reasons (RR = 1.91; 95% CI 1.12-3.27); in patients with longer hospital stays (RR = 1.04; 95% CI 1.03-1.06); high blood pressure (RR = 1.76; 95% CI 1.17-2.64); or had a risk for undernutrition (RR = 3.51; 95% CI 1.71-7.24). Higher scores in the Braden scale was associated with a decreased risk of PI (RR = 0.79; 95% CI 0.75-0.83). The results of our study indicate that 5.9% of all patients developed PI and that the most important factors that nurses should consider are: patient age, care setting, length of hospitalization, comorbidities, reason for admission and nutrition when planning and implementing PI-preventative actions.

The Japanese registry for surgery of ischial pressure ulcers: STANDARDS-I

Objective:

To clarify the surgical indications and the appropriate perioperative management of ischial pressure ulcers (PUs).

Method:

A two-year prospective, nationwide registry study was carried out across 26 medical institutions in Japan. All participating institutions managed ischial PUs according to the standardisation of total management and surgical application for the refractory decubitus (STANDARDS-I) perioperative protocol. Analysis was conducted on a range of clinically or statistically important variables for the achievement of primary or secondary endpoints: complete wound healing and hospital discharge at three months, and complete wound healing at one month after surgery, respectively.

Results:

A total of 59 patients took part in the study. All patients underwent surgery for ischial PUs during the study period. Patients who had achieved the primary endpoint had a higer preoperative functional independence measurement (FIM score), a higher ‘G’ score in the DESIGN-R scale and were more likely to have healed by primary intention. Patients who had achieved the secondary endpoint were more likely to have spastic paralysis, preoperative physiotherapy and localised infection of the wound, among other variables.

Conclusion:

This survey suggests that preoperative physiotherapy increases the speed of wound healing, and good granulation of the wound bed preoperatively increases the likelihood of woundless discharge from hospital, whereas the existence of comorbidities negatively influences the likelihood of woundless discharge from hospital. The study also suggests that the existence of spastic paralysis, preoperative infection of the wound, or surgical reduction of the ischial tubercle speeds up the healing of the wound. However, the wound failed to heal significantly more often in patients with increasing white blood cell count after surgery.

Ultrasound assessment of deep tissue on the wound bed and periwound skin: A classification system using ultrasound images

AIMS

Given the utility of ultrasonography in assessing pressure injury, some ultrasonographic findings have already been used as indicators of deep tissue pressure injury. Despite reports showing that a cloud-like ultrasonographic pattern reflected the presence of deep tissue necrosis, identifying cloud-like patterns was difficult given the presence of similar findings, such as a cobblestone-like pattern. This case series reports patients with pressure injuries who presented with a cloud-like (five cases) and cobblestone-like (four cases) pattern during ultrasonography.

METHODS

This study was conducted at a Japanese university hospital. Participants included patients who underwent routine examination by an interdisciplinary pressure injury team. Pressure injury severity was assessed using the DESIGN-R® scoring system and the wound size were measured using ImageJ software based on the wound photograph.

RESULTS

Among the five cases showing a cloud-like pattern upon ultrasonography, all exhibited an increase in the total DESIGN-R® score, while three exhibited an increase in wound size. On the other hand, all four cases showing a cobblestone-like pattern displayed no increase in the total DESIGN-R® score and a decrease in wound size.

CONCLUSION

This study suggested that distinguishing between cloud-like and cobblestone-like ultrasonography patterns is necessary for determining the presence or absence of deep tissue pressure injury. In order to comprehensively assess pressure injuries with ultrasonography, future studies should be conducted in a large number of participants.

Stability of Skin Microbiome at Sacral Regions of Healthy Young Adults, Ambulatory Older Adults, and Bedridden Older Patients After 2 Years

OBJECTIVE

The sacral skin of bedridden older patients often develops a dysbiotic condition. To clarify whether the condition changes or is sustained over time, we analyzed the skin microbiome and the skin physiological functions of the sacral skin in patients who completed our 2017 study.

METHODS

In 2019, we collected the microbiome on the sacral region and measured sacral skin hydration, pH, and transepidermal water loss from 7 healthy young adults, 10 ambulatory older adults, and 8 bedridden older patients, all of whom had been recruited for the 2017 study. For microbiome analysis, 16S ribosomal RNA-based metagenomic analysis was used.

RESULTS

No significant differences in the microbial compositions or any alpha diversity metrics were found in the bedridden older patients between the 2017 and 2019 studies; the higher gut-related bacteria were still observed on the sacral skin of the bedridden older patients even after 2 years. Only skin pH showed a significant decrease, approaching normal skin condition, in the bedridden older patients over 2 years.

CONCLUSION

This study indicated that gut-related bacteria stably resided in the sacral skin in bedridden patients, even if the patient had tried to restore skin physiological functions using daily skin care. We propose the importance of skin care that focuses more on bacterial decontamination for the sacral region of bedridden older patients, in order to decrease the chances of skin/wound infection and inflammation.

Skin Physiology and its Microbiome as Factors Associated with the Recurrence of Pressure Injuries

BACKGROUND

Preventing recurrent pressure injuries (RPIs) is one of the important challenges faced in healthcare, but the risk factors of RPIs have not been fully revealed. This study aims to explore factors associated with RPIs, by focusing on skin physiology and its microbiome as local factors crucial for the health of healed tissue after pressure injury healing.

METHODS

This prospective observational study was conducted in a long-term care facility in Japan with patients whose PIs had healed within 1 month. Skin physiology was evaluated by stratum corneum (SC) hydration, pH, and transepidermal water loss. Skin bacteria was collected by tape stripping, followed by 16S ribosomal RNA-based metagenomics analysis. These parameters were evaluated every two weeks over a period of six weeks.

RESULTS

A total of 30 patients were included in this study, and 8 patients (26.7%) had an RPI within 6 weeks. In this study, significantly lower SC hydration and a higher rate of Staphylococcus species on the healed site were found in the RPI group.

DISCUSSION

A high rate of RPIs (about one in four) points out the necessity of a further care strategy on the healed PIs. Lower skin hydration and/or the increase in Staphylococcus bacteria may have a potential to be used as a biomarker for the prediction of RPIs, or may be an intervention point for the prevention of RPIs by, for example, skin cleansing with moisturizing care.

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

OBJECTIVE

Pressure ulcers (PUs) involve the destruction of skin and underlying tissue due to prolonged pressure and shear forces. These ulcers are painful and significantly reduce a person's quality of life. PUs are also expensive to manage and impact negatively on the achievement of cost-effective, efficient care delivery.

METHOD

Prone positioning is a postural therapy that aims to enhance respiratory function through increasing oxygenation levels. In contemporary clinical practice, ventilation in the prone position is indicated for patients with severe acute respiratory distress syndrome. However, despite its advantages in terms of respiratory function, several studies have examined complications of prone position ventilation and have identified PUs (facial PUs as well as PUs on other weight-bearing areas of the body) as a frequent complication in patients who are already in a precarious medical situation. International data suggest that up to 57% of patients nursed in the prone position develop a PU. The aim of this clinical review is to identify and review evidence-based recommendations developed to facilitate the selection and application of preventive interventions aimed at reducing PU development in patients ventilated in the prone position. Given the current COVID-19 crisis, this review is timely as intensive care unit (ICU) patients with COVID-19 require ventilation in the prone position at a level that is disproportionate to the general intensive care population. Up to 28% of patients admitted to the ICU with confirmed infection due to severe COVID-19 are cared for in the prone position. The scope of this review is limited to adult individuals only.

RESULTS

The skin assessment should be undertaken before proning and following positioning the patient back into the supine position. Although it is essential to keep the skin clean and moisturised, using pH-balanced cleansers, there is inconsistency in terms of the evidence to support the type of moisturiser. Use of positioning devices in addition to repositioning is recommended to offload pressure points on the face and body. Further, using dressings such as hydrocolloids, transparent film and silicone may be of benefit in decreasing facial skin breakdown.

CONCLUSION

Given the importance of PU prevention in this cohort of patients, adopting a focused prevention strategy, including skin assessment and care, offloading and pressure redistribution, and dressings for prevention may contribute to a reduction in the incidence and prevalence of these largely preventable wounds.

Comparison of platelet-rich plasma gel in the care of the pressure ulcers with the dressing with serum physiology in terms of healing process and dressing costs

This research was carried out with the aim of comparing the effects of platelet-rich plasma (PRP) gel and gas dressing with serum physiologic applied to stage II pressure ulcer in coccyx of patients for 2 months on healing process and dressing costs. This prospective randomised controlled experimental study was conducted with 60 patients hospitalised in the palliative care unit after surgery. The experimental group (n = 30) was dressed with platelet-rich plasma gel. The control group (n = 30) was treated with serum physiologic dressing. At the end of the 20th observation of the patients in the experimental group, it was found that the mean scores of area, exudate, and tissue type in pressure sores decreased statistically (P < .001). In the control group, no significant difference was found between the mean PUSH score at the end of the 20th observation (P > .05). The study showed that PRP gel had a positive effect on healing of stage II pressure ulcers with platelet-rich plasma gel dressings. In addition, when evaluated in the long term, it was concluded that platelet-rich plasma gel is easily accessible and less costly than serum physiological dressing.

Do we still need to assess nurses' attitudes towards pressure ulcer prevention? A systematic review

OBJECTIVE

To critically appraise and synthesise existing research literature pertaining to nurses' attitudes towards pressure ulcer (PU) prevention.

METHOD

Using systematic review methodology, published quantitative studies focusing on nurses' attitudes towards PU prevention measured by psychometric tests were included. The search was conducted in May 2019 using PubMed, CINAHL, Scopus, Cochrane and EMBASE databases, and returned 442 records, of which 21 met the inclusion criteria. Data were extracted using a pre-designed extraction tool and all included studies were quality appraised using the checklist.

RESULTS

Of the included studies, 20 employed a cross-sectional design and one author employed a validation study. In measuring nurses' attitudes toward PU prevention two distinct instruments were used: the 'Moore and Price Attitude Scale' and the 'Attitude towards Pressure Ulcer Prevention Instrument'. The mean attitude score within the studies was 73% (standard deviation=9.2%). The lowest attitude score was 51%, while the highest score was 89%. The results obtained from the studies indicated that 86% (n=18) yielded positive attitude results.

CONCLUSION

The findings suggest that, overall, nurses are positively disposed towards PU prevention. However, it is important to highlight that the nurses have difficulties translating this positive attitude into actual PU prevention strategies.

Effects of pressure ulcer prevention training among nurses in long-term care hospitals

BACKGROUND

Nurses caring for elderly patients with a high risk of pressure ulcer at long-term care hospitals require the necessary knowledge, behaviors, and attitudes regarding preventing pressure ulcers.

OBJECTIVES

To identify the effects of pressure ulcer prevention training on nurses' knowledge, behaviors, and attitudes regarding pressure ulcer prevention.

DESIGN

A comparison group pretest-posttest design.

SETTINGS

Long-term care hospitals in a metropolitan area of the Republic of Korea.

PARTICIPANTS

Participants were conveniently assigned to team-based learning (n = 30) or lecture-based learning (n = 30) groups.

METHODS

We examined pre-post differences in the scores for pressure ulcer prevention knowledge, behaviors, and attitudes in each group using the paired t-test. Additionally, pre-post difference scores were compared between the two groups using the independent samples t-test.

RESULTS

Both groups exhibited significant increases in scores for pressure ulcer prevention knowledge, behaviors, and attitudes after the intervention as compared before it. However, we found no significant differences in the pre-post difference scores for any of the variables between the two groups.

CONCLUSIONS

Pressure ulcer prevention training, regardless of whether it utilizes team-based or lecture-based learning, is useful for enhancing nurses' pressure ulcer prevention knowledge, behaviors, and attitudes. Further study is needed to verify the longitudinal effects of pressure ulcer prevention training on nurses' actual performance and the incidence of pressure ulcers among patients.

Effectiveness and safety of olive oil preparation for topical use in pressure ulcer prevention: Multicentre, controlled, randomised, and double-blinded clinical trial

This non-inferiority, multicentre, randomised, controlled, and double-blinded clinical trial compared the therapeutic effectiveness of the topical application of an olive oil solution with that of a hyperoxygenated fatty acid compound for the prevention of pressure ulcers in at-risk nursing home residents. The study population comprised 571 residents of 23 nursing homes with pressure ulcer risk, randomly assigned to a hyperoxygenated fatty acid group (n = 288) or olive oil solution group (n = 283). Both solutions were applied on at-risk skin areas every 12 hours for 30 days or until pressure ulcer onset. The main outcome variable was the pressure ulcer incidence. The absolute risk difference was estimated (with 95% CI) using Kaplan-Meier survival and Cox regression curves. The groups did not significantly differ in any study variable at baseline. The pressure ulcer incidence was 4.18% in the olive oil group vs 6.57% in the control group, with an incidence difference of -2.39% (95% CI = -6.40 to 1.56%), which is within the pre-established non-inferiority margin of ±7%, thus supporting the study hypothesis. We present the first evidence of the effectiveness and safety of the topical application of olive oil to prevent pressure ulcers in the institutionalised elderly.

Using the Braden subscales to assess risk of pressure injuries in adult patients: A retrospective case-control study

The aim of this study was to compare the pressure injury risk predictability between the individual Braden subscales and the total Braden scale in adult inpatients in Singapore. A retrospective 1:1 case-control design was used from a sample of 199 patient medical records. Clinical data were collected from a local university hospital's medical records database. The results showed that, among the six subscales, the activity subscale was the most sensitive and specific in predicting pressure injury (PI). However, the overall results showed that the Braden scale remained the most predictive of PI development in comparison with the individual subscales. The study also found that, among the Singaporean patients, the Braden cut-off score for PI risk was 17 compared with the current cut-off score of 18. Therefore, it may be relevant for local tertiary hospitals to review their respective Braden cut-off scores as the study results indicate an over-prediction of PI risk, which leads to unnecessary utilisation of resources. The hospital may also consider developing a PI prevention bundle comprising commonly used preventive interventions when at least one Braden subscale reflects a suboptimal score.

The prevalence, incidence, and associated factors of pressure injuries among immobile inpatients: A multicentre, cross-sectional, exploratory descriptive study in China

The aim of this study was to assess the prevalence, incidence, and the associated factors of pressure injuries (PIs) among immobile hospitalised patients in China. Being immobile during hospitalisation put these patients at a higher risk of PIs. There is little literature about pressure injury (PI) prevalence or PI incidence in immobile hospitalised patients in hospitals in China. This was a multicentre, cross-sectional, exploratory descriptive study. A total of 23 985 immobile patients were recruited from 25 general hospitals in six provinces of China from November 1, 2015 to March 18, 2016. Information was collected on demographic characteristics, physical assessment information, and treatment and nursing care measures. The PI period prevalence was 3.38%, and the PI cumulative incidence was 1.23%. Most PIs (84.03%) were Stage 1 or Stage 2. A total of 48.22% of PIs occurred in the sacrum or heel region. In the multivariate analysis, the following factors were associated with higher PI prevalence: age, gender, length of immobility, type of hospital, modified Braden Scale score, urinary incontinence, faecal incontinence, low serum albumin, the usage of fixation or restraint devices, and patient's discharge diagnosis (lower limb fracture, malnutrition, and spinal cord injury). PI prevalence for immobile hospitalised patients in the study was lower than those reported in literature. However, because of the large population in China, the number of patients who suffer with PIs can be very high. The relating factors of higher PI prevalence identified in this study were consistent with current literature. Patients with a higher number of these associated factors should be monitored more closely, and preventative measures should be taken to prevent PI occurrence in high-risk populations.

Nurses' and Care Workers' Perception of Care Quality in Japanese Long-Term Care Wards: A Qualitative Descriptive Study

Despite the growing importance of long-term care for older adults, there has been limited attention to its quality assurance issues in Japan. To start planning the initiation of continuous quality improvement in long-term care hospitals, we explored how nurses and care workers themselves perceived current approaches to quality assurance and improvement on their ward. We interviewed 16 licensed nurses and nine care workers, transcribed and analyzed data using qualitative content analysis techniques, and derived six categories: keeping clients alive is barely possible, the absence of a long-term care practice model, the lack of quality indicators, long-term care hospitals as places for castaways, client quality of life as a source of satisfaction, and conflict between staff and client well-being. To develop continuous quality improvement in Japanese long-term care hospitals, it may be first necessary to introduce a practice model of long-term care and mechanisms to evaluate quality.

Usefulness of the Braden Scale in Intensive Care Units: A Study Based on Electronic Health Record Data

Nurses working in intensive care units have expressed concern that some categories of the Braden scale such as activity and nutrition are not suitable for intensive care unit patients. Upon examining the validity of the Braden scale using the electronic health data, we found relatively low predictability of the tool. Risk factors from the sensory perception and activity categories were not associated with risk of pressure ulcers.

Prevalence of pressure injuries in Japanese older people: A population-based cross-sectional study

Objectives

The prevalence of pressure injuries is an essential indicator of prevention and quality of care. Population-based prevalence data on pressure injuries are scarce in Japan. This study aimed to estimate the prevalence of pressure injuries per 1000 adults and per 1000 older people in Japan.

Design

Cross-sectional survey.

Setting

This study was conducted in Goto, a city located on a remote rural archipelago in Japan. In 2017, the population was 37,855; older people aged ≥65 years accounted for 37.7%.

Participants

Participants were enrolled in various facilities in the city. In total, 1126 participants (median age 85 years) were assessed to calculate age-specific numbers of people with pressure injuries.

Measurements

Participants were directly evaluated by the research team between August and September 2017, and pressure injuries were classified using DESIGN-R schema. We calculated the number of adults with pressure injuries in Goto based on the proportion of pressure injuries in specific age categories. In these prevalence estimations, we assumed that all cases aged ≥65 years were long-term care insurance-certified older people, and all cases aged 18–64 years were people with physical disabilities who received social welfare services.

Results

Of the 1126 participants, 113 (10%) had one or more pressure injuries. Overall, the estimated number of adults with pressure injuries in Goto was 301.4. The prevalence rate of pressure injuries was 9.2 per 1000 population in adults aged ≥18 years (95% confidence interval [CI] 8.1–10.2), 20.3 in those aged ≥65 years (95% CI 18.1–22.7), and 44.6 in those aged ≥80 years (95% CI 39.5–50.2).

Conclusions

This study revealed a high population-based prevalence of pressure injuries in a rural Japanese community. A key reason for this high disease burden in Japan appears to be the susceptibility of the aged population to pressure injuries.

Effectiveness of Topical Sucralfate in the Management of Pressure Ulcer in Hospitalized Patients: A Prospective, Randomized, Placebo-Controlled Trial

BACKGROUND

The aim of this study was to evaluate the effectiveness of topical sucralfate in the management of pressure ulcer (PU) in hospitalized patients.

METHODS

Forty hospitalized patients with stage II PU were included in this prospective, double-blind, randomized, placebo-controlled trial and were randomly divided into 2 groups receiving either sucralfate gel or placebo, on a daily basis. The patients were visited every day for 14 days, the ulcer was evaluated using the Pressure Ulcer Scale for Healing (PUSH) and changes to the measured scores over time were used as an indicator of wound healing.

RESULTS

There were no statistically significant differences in any of the demographic characteristics between both groups. Both of the interventions reduced the average PUSH score, and at the end of the trial, all but 2 patients were healed. One in each group discontinued the trial because of exacerbation of the ulcer. No significant between-group difference in the average PUSH score reduction was observed (6.36 ± 2.11 vs. 5.89 ± 1.41, P = 0.42). Although the average healing time was less in the sucralfate group (6.05 ± 2.17 vs. 7.78 ± 3.42), the difference was not statistically significant (P = 0.07).

CONCLUSIONS

Sucralfate gel does not improve healing of PU compared with placebo.

The Japanese registry for surgery of ischial pressure ulcers: STANDARDS-I

OBJECTIVE

To clarify the surgical indications and the appropriate perioperative management of ischial pressure ulcers (PUs).

METHOD

A two-year prospective, nationwide registry study was carried out across 26 medical institutions in Japan. All participating institutions managed ischial PUs according to the standardisation of total management and surgical application for the refractory decubitus (STANDARDS-I) perioperative protocol. Analysis was conducted on a range of clinically or statistically important variables for the achievement of primary or secondary endpoints: complete wound healing and hospital discharge at three months, and complete wound healing at one month after surgery, respectively.

RESULTS

A total of 59 patients took part in the study. All patients underwent surgery for ischial PUs during the study period. Patients who had achieved the primary endpoint had a higer preoperative functional independence measurement (FIM score), a higher 'G' score in the DESIGN-R scale and were more likely to have healed by primary intention. Patients who had achieved the secondary endpoint were more likely to have spastic paralysis, preoperative physiotherapy and localised infection of the wound, among other variables.

CONCLUSION

This survey suggests that preoperative physiotherapy increases the speed of wound healing, and good granulation of the wound bed preoperatively increases the likelihood of woundless discharge from hospital, whereas the existence of comorbidities negatively influences the likelihood of woundless discharge from hospital. The study also suggests that the existence of spastic paralysis, preoperative infection of the wound, or surgical reduction of the ischial tubercle speeds up the healing of the wound. However, the wound failed to heal significantly more often in patients with increasing white blood cell count after surgery.

Prevalence, characteristics and risk factors of pressure ulcers in public and private hospitals care units and nursing homes in France

OBJECTIVE

The aim of this study conducted in 2014 was to describe the prevalence of pressure ulcers in different types of French hospital unit at the national level to compare them with data from the 1994 and 2004 study.

METHODS

This cross-sectional study was conducted over a single day. All care units were invited to participate by drawing lots stratified by region in successive waves until 1,200 agreements were obtained. Lots were drawn for towns with more than 10,000 inhabitants. All public- and private-sector hospital facilities in each town drawn by lot were invited to participate in the survey.

RESULTS

776 hospital services throughout France took part and accommodated 21,538 patients: 12,752 women (59.2%) and 8,786 men (40.8%). Of these patients, 1,753 (8.1%; IC95% = 7.7; 8.5) had pressure ulcers. The pressure-ulcer rate was 7.8% (IC95% = [7.3; 8.3] (n = 997)) for hospitalized women and 8.6% (IC95% = [8.0; 9.2] (n = 756)) for men (p = 0.0381). The 8.1% level reported in 2014 therefore points to a reduction in pressure-ulcer prevalence; 8.6% in 1994 and 8.9% in 2004.

CONCLUSIONS

The actions performed daily by healthcare professionals to prevent pressure ulcers, supported by research and training programs, including those by PERSE, are having a real impact over time.

Pressure injury identification, measurement, coding, and reporting: Key challenges and opportunities

Pressure injury (PI) rates are a commonly used indicator of performance of health care facilities, both in acute and subacute settings. However, measuring PI rates in an accurate and reproducible fashion has been challenging. The consequences of poor measurement may include failure to identify poorly performing institutions or incorrect accusations of poor quality care. In this article, we describe the main challenges in identification, coding, and reporting of PIs. Issues include inconsistent identification of PIs at the time of admission, variations in the intensity of PI detection, and differing approaches to coding and the adjustment for differing risks amongst different patient population. These are compounded by differences in the epidemiological approach because rates will differ according to whether patients are surveyed cross-sectionally (eg, on a set day per month) or if the survey is undertaken at discharge. In some cases, financial incentives may also influence PI reporting. We also discuss potential strategies for improving data collection and benchmarking as an aid to reducing PI prevalence.

Process evaluation of a cluster-randomised trial testing a pressure ulcer prevention care bundle: a mixed-methods study

BACKGROUND

As pressure ulcers contribute to significant patient burden and increased health care costs, their prevention is a clinical priority. Our team developed and tested a complex intervention, a pressure ulcer prevention care bundle promoting patient participation in care, in a cluster-randomised trial. The UK Medical Research Council recommends process evaluation of complex interventions to provide insight into why they work or fail and how they might be improved. This study aimed to evaluate processes underpinning implementation of the intervention and explore end-users' perceptions of it, in order to give a deeper understanding of its effects.

METHODS

A pre-specified, mixed-methods process evaluation was conducted as an adjunct to the main trial, guided by a framework for process evaluation of cluster-randomised trials. Data was collected across eight Australian hospitals but mainly focused on the four intervention hospitals. Quantitative and qualitative data were collected across the evaluation domains: recruitment, reach, intervention delivery and response to intervention, at both cluster and individual patient level. Quantitative data were analysed using descriptive and inferential statistics. Qualitative data were analysed using thematic analysis.

RESULTS

In the context of the main trial, which found a 42% reduction in risk of pressure ulcer with the intervention that was not significant after adjusting for clustering and covariates, this process evaluation provides important insights. Recruitment and reach among clusters and individuals was high, indicating that patients, nurses and hospitals are willing to engage with a pressure ulcer prevention care bundle. Of 799 intervention patients in the trial, 96.7% received the intervention, which took under 10 min to deliver. Patients and nurses accepted the care bundle, recognising benefits to it and describing how it enabled participation in pressure ulcer prevention (PUP) care.

CONCLUSIONS

This process evaluation found no major failures relating to implementation of the intervention. The care bundle was found to be easy to understand and deliver, and it reached a large proportion of the target population and was found to be acceptable to patients and nurses; therefore, it may be an effective way of engaging patients in their pressure ulcer prevention care and promoting evidence-based practise.

Factors associated with the incidence of pressure ulcer during hospital stay

Abstract OBJECTIVE Estimating the incidence rate of pressure ulcers and verifying factors associated with this occurrence in a cohort of hospitalized patients. METHOD This is a cohort study in which the considered outcome was the time until pressure ulcer occurrence. Estimated effect of the variables on the cumulative incidence ratio of the outcome was performed using the Cox proportional hazards model. Variable selection occurred via the Logrank hypothesis test. RESULTS The sample consisted of 442 adults, with 25 incidents of pressure ulcers. Patients with high scores on the Braden scale presented a higher risk of pressure ulcer incidence when compared to those classified into the low score category. CONCLUSION These results reinforce the importance of using the Braden Scale to assist in identifying patients more likely to develop pressure ulcers.

Analyses of pressure ulcer incidence in inpatient setting in a Portuguese hospital

AIM

To gain more insight into the magnitude of the problem of pressure ulcer incidence in general wards of a Portuguese hospital.

MATERIAL AND METHODS

Retrospective cohort analysis of electronic health record database from 7132 adult patients admitted to medical and surgical wards of Aveiro Hospital during 2012. The development of (at least) one pressure ulcer during the length of stay was associated with age, gender, type of admission, specialty units, first Braden Scale score, length of stay, patient discharge outcome and ICD-9 diagnosis.

RESULTS

An incidence of 3.4% participants with pressure ulcer category I-IV in inpatient setting during 2012. During the length of stay, 320 new pressure ulcers were developed, most of them category/stage II. The sacrum/coccyx and the trochanters were the most problematic areas.

CONCLUSIONS

The major risk factor for the development of a new pressure ulcer during the length of stay was the presence of (at least) one pressure ulcer at the first skin assessment. The length of stay itself, age and lower Braden Scale scores of our participants also played an important role in the odds of developing a pressure ulcer. Infectious diseases, traumatism and fractures and respiratory diseases were the ICD-9 diagnoses with higher frequency of participants that developed (at least) one pressure ulcer during the length of stay. It's important to standardize procedures and documentation in all care settings. The documentation of nursing interventions is vital to evaluate the impact of evidence-based nursing.

Analyses of pressure ulcer point prevalence at the first skin assessment in a Portuguese hospital

AIM

To analyze the first pressure ulcer risk and skin assessment records of hospitalized adult patients in medical and surgical areas of Aveiro Hospital during 2012 in association with their demographic and clinical characteristics.

MATERIAL AND METHODS

Retrospective cohort analysis of electronic health record database from 7132 adult patients admitted to medical and surgical areas in a Portuguese hospital during 2012. The presence of (at least) one pressure ulcer at the first skin assessment in inpatient setting was associated with age, gender, type of admission, specialty units, length of stay, patient discharge and ICD-9 diagnosis.

RESULTS

Point prevalence of participants with pressure ulcer category/stage I-IV of 7.9% at the first skin assessment in inpatient setting. A total of 1455 pressure ulcers were documented, most of them category/stage I. The heels and the sacrum/coccyx were the most problematic areas. Participants with pressure ulcer commonly had two or more pressure ulcers.

CONCLUSIONS

The point prevalence of participants with pressure ulcer of our study was similar international literature. The presence of a pressure ulcer at the first skin assessment could be an important measure of frailty and the participants with pressure ulcer commonly had more than one documented pressure ulcer. Advanced age or lower Braden Scale scores or Emergency Service admission were relevant variables for the presence of (at least) one pressure ulcer at the first skin assessment in inpatient setting as well as respiratory, infectious or genitourinary system diseases.

Costs of topical treatment of pressure ulcer patients

Abstract OBJECTIVE To evaluate the costs of a topical treatment of pressure ulcer (PU) patients in a hospital unit for treatment of chronic patients in 2014. METHOD This is an activity-based costing study. This method encompasses the identification, measurement and pricing of physical and human resources consumed for dressings. RESULTS Procedure costs varied between BRL 16.41 and BRL 260.18. For PUs of the same category, of near areas and with the same type of barrier/adjuvant, the cost varied between 3.5% and 614.6%. For most dressings, the cost increased proportionally to the increase of the area and to the development of PU category. The primary barrier accounted for a high percentage of costs among all items required to the application of dressings (human and material resources). Dressings applied in sacral PUs had longer application times. CONCLUSION This study allowed us to understand the costs involved in the treatment of PUs, and it may support decision-makers and other cost-effectiveness studies.

Prevention of heel pressure ulcers among older patients--from ambulance care to hospital discharge: A multi-centre randomized controlled trial

The aim was to investigate the effect of an early intervention, a heel suspension device boot, on the incidence of heel pressure ulcers among older patients (aged 70+).

BACKGROUND

Pressure ulcers are a global healthcare issue; furthermore, the heel is an exposed location. Research indicates that preventive nursing interventions starting during the ambulance care and used across the acute care delivery chain are seldom used.

METHODS

A multi-centre randomized control study design was used. Five ambulance stations, two emergency departments and 16 wards at two Swedish hospitals participated. Altogether, 183 patients were transferred by ambulance to the emergency department and were thereafter admitted to one of the participating wards.

RESULTS

Significantly fewer patients in the intervention group (n=15 of 103; 14.6%) than the control group (n=24 of 80; 30%) developed heel pressure ulcers during their hospital stay (p=0.017).

CONCLUSIONS

Pressure ulcer prevention should start early in the acute care delivery chain to increase patient safety.

Wound-care teams for preventing and treating pressure ulcers

BACKGROUND

Pressure ulcers, which are localised injury to the skin or underlying tissue, or both, occur when people are unable to reposition themselves to relieve pressure on bony prominences. Pressure ulcers are often difficult to heal, painful and impact negatively on the individual's quality of life. The cost implications of pressure ulcer treatment are considerable, compounding the challenges in providing cost effective, efficient health service delivery. International guidelines suggest that to prevent and manage pressure ulcers successfully a team approach is required. Therefore, this review has been conducted to clarify the role of wound-care teams in the prevention and management of pressure ulcers.

OBJECTIVES

To assess the impact of wound-care teams in preventing and treating pressure ulcers in people of any age, nursed in any healthcare setting.

SEARCH METHODS

In April 2015 we searched: The Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE and EBSCO CINAHL. There were no restrictions with respect to language, date of publication or study setting.

SELECTION CRITERIA

We considered RCTs that evaluated the effect of any configuration of wound-care teams in the treatment or prevention of pressure ulcers.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed titles and, where available, abstracts of the studies identified by the search strategy for their eligibility. We obtained full versions of potentially relevant studies and two review authors independently screened these against the inclusion criteria.

MAIN RESULTS

We identified no studies that met the inclusion criteria.

AUTHORS' CONCLUSIONS

We set out to evaluate the RCT evidence pertaining to the impact of wound-care teams on the prevention and management of pressure ulcers. However, no studies met the inclusion criteria. There is a lack of evidence concerning whether wound-care teams make a difference to the incidence or healing of pressure ulcers. Well-designed trials addressing important clinical, quality of life and economic outcomes are justified, based on the incidence of the problem and the high costs associated with pressure ulcer management.
