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

BACKGROUND: Pressure injuries are a common and serious issue for bedridden residents in long-term-care facilities. Areas of bony prominences, such as the scapula, sacrum, and heels, are more likely to develop pressure injuries. The management of pressure injury wounds include dressing changes, repositioning, away from moisture, decreasing the occurrence of friction and shear, and more. Some supportive surfaces are also used for pressure injury cases such as gel pads, alternating pressure air mattresses, and air-fluidized beds. The aim of this case study was to determine whether the use of an artificial intelligent mattress can improve a nursing home resident with prolonged pressure injury. CASE PRESENTATION: A retrospective study design was conducted for this case study. A 79-year-old male developed a pressure injury in the sacrum. His pressure injury was initially at stage 4, with a score of 12 by the Braden scale. The PUSH score was 16. During 5.5 months of routine care plus the use of the traditional alternative air mattress, in the nursing home, the wound stayed in stage 3 but the PUSH score increased up to 11. An artificial intelligence mattress utilizing 3D InterSoft was used to detect the bony prominences and redistribute the external pressure of the skin. It implements a color guided schematic of 26 colors to indicate the amount of pressure of the skin. RESULTS: The wound size was decreased and all eczema on the resident's back diminished. The PUSH score was down to 6, as the artificial intelligent mattress was added into the routine care. The staff also reported that the resident's quality of sleep improved and moaning decreased. The hemiplegic side is at greater risk of developing pressure injury. CONCLUSIONS: This novice device appeared to accelerate wound healing in this case. In the future, more cases should be tested, and different care models or mattress can be explored.

Hospital-acquired pressure injury: our seven years of experience.

OBJECTIVE: A pressure injury (PI) happens on the skin and in deeper tissues. Generally, it occurs due to prolonged compression over bony structures. A PI, when occurring during a hospital stay, is regarded as a hospital-acquired pressure injury (HAPI), and is considered as a marker for patient care quality. It might cause medical, legal or economic problems, and could be a burden on health systems. In this study we evaluate the factors contributing to HAPI formation. METHOD: Between June 2014-June 2021, we retrospectively investigated the files of patients who were hospitalised with different medical conditions in Bayindir Sögütözü Hospital, Ankara, Turkey, for patients' age, sex, Waterlow scale score, mobilisation status, application of zinc-containing and/or barrier creams (ZnBC), airbed usage, hospitalisation period, and the day of wound opening. RESULTS: The study cohort comprised 2327 hospitalised patients: 303 (13%) developed Stage 2 and deeper PIs; 2024 patients were hospitalised and discharged without wound opening. We found an increased risk in male patients and a lack of efficacy of ZnBC in protection from HAPI in our study population. However, we observed that ZnBC helped to delay wound opening and that the most protective treatment was the use of airbeds. CONCLUSION: Health professionals should be more aware of HAPI formation with prolonged hospitalisation periods. Only the use of an airbed for a patient hospitalised for a long period appears to be protective against PI formation. On the other hand, use of ZnBC delays wound opening. However, further research is needed to demonstrate the protective effect of ZnBC, due to the lack of randomisation in our study and the lack of some nursing records.

Comparison of the Predictive Validity of Norton and Braden Scales in Determining the Risk of Pressure Injury in Elderly Patients.

AIM: To compare the reliability and predictive validity of Norton and Braden scales in determining the risk of pressure injury in elderly patients. DESIGN: This research used a comparative design. One hundred thirty elderly patients participated in the study. METHODS: The daily pressure injury risk of participants was evaluated by a researcher using both the Norton and Braden scales in a consecutive manner. RESULTS: The mean age of patients was 75.1 ± 8.5 years, and that for those without and with pressure injury development was 75.0 ± 8.3 years and 76.1 ± 9.7 years (P < .001), respectively. The reliability coefficients of the Norton and Braden scales were .82 and .89, respectively. The sensitivity, specificity, and positive and negative predictive values of the Norton Scale were 100%, 40.7%, 20.2%, and 100%, and those of the Braden Scale were 100%, 32.7%, 18.3%, and 100%, respectively. CONCLUSIONS: The reliability of both scales for elderly patients was found to be high, and their ability to differentiate patients at risk was comparable. However, both scales had low specificity. Further research is needed to develop scales that have higher predictive validity for the elderly population, taking into account other risk factors that influence total scale scores.

Predicting pressure injury risk in hospitalised patients using machine learning with electronic health records: a US multilevel cohort study.

OBJECTIVE: To predict the risk of hospital-acquired pressure injury using machine learning compared with standard care. DESIGN: We obtained electronic health records (EHRs) to structure a multilevel cohort of hospitalised patients at risk for pressure injury and then calibrate a machine learning model to predict future pressure injury risk. Optimisation methods combined with multilevel logistic regression were used to develop a predictive algorithm of patient-specific shifts in risk over time. Machine learning methods were tested, including random forests, to identify predictive features for the algorithm. We reported the results of the regression approach as well as the area under the receiver operating characteristics (ROC) curve for predictive models. SETTING: Hospitalised inpatients. PARTICIPANTS: EHRs of 35 001 hospitalisations over 5 years across 2 academic hospitals. MAIN OUTCOME MEASURE: Longitudinal shifts in pressure injury risk. RESULTS: The predictive algorithm with features generated by machine learning achieved significantly improved prediction of pressure injury risk (p<0.001) with an area under the ROC curve of 0.72; whereas standard care only achieved an area under the ROC curve of 0.52. At a specificity of 0.50, the predictive algorithm achieved a sensitivity of 0.75. CONCLUSIONS: These data could help hospitals conserve resources within a critical period of patient vulnerability of hospital-acquired pressure injury which is not reimbursed by US Medicare; thus, conserving between 30 000 and 90 000 labour-hours per year in an average 500-bed hospital. Hospitals can use this predictive algorithm to initiate a quality improvement programme for pressure injury prevention and further customise the algorithm to patient-specific variation by facility.

Evaluating the efficacy of standardized pressure ulcer management protocols in the prevention of pressure injuries among patients undergoing neurosurgical procedures.

Pressure injuries are a significant concern for patients undergoing neurosurgical procedures due to prolonged immobility and the complexity of care. This study evaluates the efficacy of standardized pressure ulcer management protocols in preventing pressure injuries and enhancing patient care in a neurosurgical context. A comprehensive retrospective analysis was conducted at a single institution from December 2020 to December 2023, comparing 50 patients who received standardized pressure ulcer management (intervention group) with 50 patients who received conventional care (control group). The study assessed the incidence of pressure ulcers, patient comfort levels using the Kolcaba Comfort Scale and sleep quality using the Richards-Campbell Sleep Questionnaire (RCSQ). Statistical analysis was performed using SPSS software, version 27.0, applying t-tests and chi-square tests as appropriate. The intervention group exhibited a significantly lower incidence of pressure ulcers at all measured time points post-surgery compared to the control group. Patient comfort levels in the intervention group were consistently higher across psychological, environmental, physiological and socio-cultural domains. Sleep quality metrics, including sleep depth, latency to sleep onset and overall sleep quality, were significantly improved in the intervention group. The implementation of standardized pressure ulcer management protocols in neurosurgical care significantly reduces the incidence of pressure injuries, enhances patient comfort and improves sleep quality. These findings highlight the importance of adopting structured care protocols to improve postoperative outcomes and patient well-being in neurosurgical settings.

Comparing demographics, treatments, and outcomes of patients with COVID-19 lesions versus hospital-acquired pressure ulcers/injuries during the first year of COVID-19.

BACKGROUND: As COVID-19 has emerged as a pandemic virus, multiple reports have surfaced to describe skin lesions that occur either associated with the virus or due to treatment. OBJECTIVE: To compare patient demographics, treatments, and outcomes in COVID-19 symptomatic patients who developed skin lesions (COVID-19 or hospital-acquired pressure ulcer/injury [HAPU/I]) during the first year of the pandemic. METHODS: A retrospective chart review was conducted on COVID-positive symptomatic patients admitted from March 1, 2020, through March 1, 2021. The authors analyzed the difference in patient demographics, patient skin tones, treatments, hospital length of stay (LOS), intensive care unit (ICU) LOS, death, and discharge disposition for those with COVID-19 lesions compared to those who developed HAPU/Is. RESULTS: Of those who developed lesions, 2.3% developed COVID-19 lesions and 7.2% developed HAPU/Is. Patients with COVID-19 lesions were more likely to be male (64%), younger (median age 60), and had a higher BMI (30) than patients with no wounds and patients with HAPU/I. CONCLUSION: This study advances the knowledge of the patient demographics and treatments that may contribute to identifying the new phenomenon of COVID lesions and how they differ from HAPU/Is.

Pressure injury risk factors in patients undergoing general anesthesia surgeries.

BACKGROUND: Pressure injuries result from prolonged pressure and lead to tissue damage, infections, extended recovery times, and an economic burden. PURPOSE: To explore risk factors for pressure injuries in patients who underwent surgery under general anesthesia. METHODS: This retrospective study included patients who underwent surgery at a regional educational hospital in southern Taiwan from January 1, 2018, through December 31, 2018. RESULTS: A comprehensive multivariate analysis was used to identify the prominent risk factors for pressure injury among the 11 231 patients enrolled in this study. These risk factors were an age of ≥65 years; surgery duration of >120 minutes; diastolic blood pressure of <60 mm Hg for >30 minutes during surgery; intraoperative use of dopamine, norepinephrine, or epinephrine as vasopressors; American Society of Anesthesiologists physical classification of III or higher; minimum intraoperative body temperature of ≤35°C; blood loss of >500 mL; and a supine or prone surgical position. CONCLUSIONS: This study identified several pressure injury risk factors related to surgical conditions and patient characteristics. Surgical teams must monitor, control, and manage these factors, prioritize staff education, and adopt preventive protocols.

[Incidence of pressure injuries associated with oxygen therapy devices in the neonatal intensive care unit]. / Incidencia de lesiones por presión asociadas a dispositivos de oxigenoterapia en la unidad de cuidados intensivos neonatales.

OBJECTIVE: The administration of oxygen therapy (O2) in neonatal intensive care units (NICU) increases the risk of developing pressure injuries (PBI). The aims of the study were to describe the incidence of PBI associated with O2 devices in the NICU, to identify, analyze and relate risk factors and the application of their preventive measures. METHODS: A retrospective, observational and analytical study of hospitalized neonates who developed PPL secondary to O2 devices in the NICU of the Miguel Servet University Hospital of Zaragoza was carried out. Socio-demographical, clinical, type of cot, humidity, temperature, type of oxygen therapy, ventilation mode, device and presence of ulcer (number, degree, location), and preventive measures were recorded. The study was approved by the Research Ethics Committee of the Autonomous Community of Aragon. Statistical analysis was performed using Jamovi 2.3.13®. RESULTS: A total of 191 neonates were included, of whom 158 (82.7%) received O2. Of those who received oxygen therapy, 64.10% (25) were infants, mean total age 5.20±8.46 days and mean weight 1,460.03±777.57 grams. 24.68% presented with device-associated PPL, with a mean number of days of admission at the time of onset of 3.98±5.03 days. 94.74% (36) of the lesions were grade I and 84.62% (33) were located in the nasal septum. CONCLUSIONS: The incidence of pressure injuries associated with different oxygen therapy devices increases with decreasing gestational age. The risk increases with hospital stay, with the presence of medical devices, in particular non-invasive mechanical ventilation, being the main causal relationship.

El riesgo aumenta con la estancia hospitalaria, siendo la presencia de dispositivos médicos, en particular la ventilación mecánica no invasiva, la principal causa.

A realist evaluation of devices used for the prevention of heel pressure ulcers: An ethnographic study of clinical practice.

BACKGROUND: It is known that heel offloading devices are widely used in clinical practice for the prevention of heel pressure ulcers, even though there is a lack of robust, good quality evidence to inform their use. OBJECTIVE: To explore how and why heel offloading devices are used (or not used) and reasoning behind their use in population at high risk of developing heel pressure ulcers. METHODS: An ethnographic study was conducted as part of a realist evaluation in three orthopaedic wards in a large English hospital. Twelve observations took place, with 49 h and 35 min of patient care observed. A total of 32 patients were observed and 19 members of the nursing team were interviewed and in-depth interviews with the three ward managers were conducted. RESULTS: Although the focus of the study was on offloading devices, constant low pressure heel specific devices were also observed in use for pressure ulcer prevention, whilst offloading devices were perceived to be for higher risk patients or those already with a heel pressure ulcer. Nursing staff viewed leadership from the ward manager and the influence of the Tissue Viability Nurse Specialists as key mechanisms for the proactive use of devices. CONCLUSIONS: This study informs trial design as it has identified that a controlled clinical trial of both types of heel specific devices is required to inform evidence-based practice. Involving the ward managers and Tissue Viability Nurse Specialists during set up phase for clinical equipoise could improve recruitment. Tweetable abstract How, for whom, and in what circumstances do devices work to prevent heel pressure ulcers? Observations of clinical practice.

Determinants of pressure injury development in patients with COVID-19.

OBJECTIVE: Pressure injuries (PIs) often develop in critically ill patients due to immobility, and underlying comorbidities that decrease tissue perfusion and wound healing capacity. This study sought to provide epidemiological data on determinants and current managements practices of PI in patients with COVID-19. METHOD: A US national insurance-based database consisting of patients with coronavirus or COVID-19 diagnoses was used for data collection. Patients were filtered by International Classification of Diseases (ICD) codes corresponding to coronavirus or COVID-19 diagnosis between 2019-2020. Diagnosis of PI following COVID-19 diagnosis was queried. Demographic data and comorbidity information was compared. Logistic regression analysis was used to determine predictors for both PI development and likelihood of operative debridement. RESULTS: A total of 1,477,851 patients with COVID-19 were identified. Of these, 15,613 (1.06%) subsequently developed a PI, and 8074 (51.7%) of these patients had an intensive care unit (ICU) admission. The average and median time between diagnosis of COVID-19 and PI was 39.4 and 26 days, respectively. PI was more likely to occur in patients with COVID-19 with: diabetes (odds ratio (OR): 1.39, 95% confidence interval (CI): 1.29-1.49; p<0.001); coronary artery disease (OR: 1.11, 95% CI: 1.04-1.18, p=0.002), hypertension (OR: 1.43, 95% CI: 1.26-1.64; p<0.001); chronic kidney disease (OR: 1.18, 95% CI: 1.10-1.26; p<0.001); depression (OR: 1.45, 95% CI 1.36-1.54; p<0.001); and long-term non-steroidal anti-inflammatory drug use (OR: 1.21, 95% CI: 1.05-1.40; p=0.007). They were also more likely in critically ill patients admitted to the ICU (OR: 1.40, 95% CI: 1.31-1.48; p<0.001); and patients requiring vasopressors (OR:1.25, 95% CI: 1.13-1.38; p<0.001), intubation (OR: 1.21, 95% CI 1.07-1.39; p=0.004), or with a diagnosis of sepsis (OR: 2.38, 95% CI 2.22-2.55; p<0.001). ICU admission, sepsis, buttock and lower back PI along with increasing Charlson Comorbidity Index (CCI) (OR: 1.04, 95% CI 1.00-1.08; p=0.043) was associated with surgical debridement. The vast majority of patients with COVID-19 did not undergo operative debridement or wound coverage. CONCLUSION: PIs are widely prevalent in patients with COVID-19, especially in those who are critically ill, yet the vast majority do not undergo operative procedures. DECLARATION OF INTEREST: The authors have no conflicts of interest to declare.

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.

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

INTRODUCTION: Despite the improvements made in recent decades, the OECD regards hospital-acquired pressure injuries (HAPI) as high priority areas for actions to ensure patient safety. This study was aimed at investigating the degree of utilization of two types of electronic patient record systems for wound care on lowering HAPI rates. Furthermore, the effect of user satisfaction with the systems and perceived alignment with clinical processes should be studied. MATERIAL AND METHODS: A regression analysis of post-stratified data from German hospitals obtained from the Hospital Quality Reports (observed/expected HAPI ratio) and the IT Report Healthcare was performed. The sample comprised 319 hospitals reporting on digital wound record systems and 199 hospitals on digital nursing record systems for system utilization and the subset of hospitals using a digital system for user satisfaction and process alignment. RESULTS: The study revealed a significant effect of hospital ownership for both types of systems and a significant interaction of ownership and system utilization for digital wound record systems: Only the for-profit hospitals benefited from a higher degree of system utilization with a lower HAPI ratio. In contrast, non-profit hospitals yielded a reversed pattern, with increasing HAPI rates matching an increased system utilization. User satisfaction (significant) and the perceived alignment of the clinical process (trend) of the digital nursing record system were related with lower HAPI ratios. DISCUSSION: These findings point to a differential effect of system utilization on HAPI ratios depending on hospital ownership, and they demonstrate that those users who are satisfied with the system can act as catalysts for better care. The explained variance was small but comparable to other studies. Furthermore, it shows that explaining quality care is a complex undertaking. Sheer utilization has no effect while a differential perspective on the facilitators and barriers might help to explain the patient outcomes.

Association between hypertension and pressure ulcer: A systematic review and meta-analysis.

This review aims to systematically evaluate the association between hypertension and pressure ulcer (PU). PubMed, Embase, Web of Science, and Cochrane Library were searched for studies from their inception until September 12, 2023. Literature search, data extraction, and quality assessment were conducted independently by two researchers. The random-effects model was used to calculate the combined odds ratio (OR) and corresponding 95% confidence interval (CI) of hypertension in patients with PU; subgroup analyses were performed to explore the source of between-study heterogeneity; sensitivity analysis was used to test the robust of the combined result; and funnel plot and Egger's test were used to assess the publication bias. Finally, a total of 19 studies with 564 716 subjects were included; the overall pooled result showed no significant association between hypertension and risk of developing PU (OR = 1.15, 95% CI = 0.90-1.47, p = 0.27); and the sensitivity analysis and publication bias analysis showed robust of the combined result. Subgroup analysis indicated a significant association between hypertension and PU when the primary disease was COVID-19 (OR = 1.73, 95% CI = 1.35-2.22, p < 0.0001). No association between hypertension and PU was seen in subgroup analysis on the patient source and study design. In sum, there is no significantly statistical association between hypertension and the occurrence of PU in most cases, while the risk of PU significantly elevates among COVID-19 patients combined with hypertension regardless of patient source and study design.

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

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

Hematologic and Serum Biochemical Values Associated With Different Stages of Hospital-Acquired Pressure Injuries in Patients: A Retrospective Study.

PURPOSE: The primary purpose of this study was to determine whether hematologic and serum biochemical values used as indicators of nutritional status, anemia, and/or infection were associated with the risk of hospital-acquired pressure injuries (PIs) and stage of PIs in patients. DESIGN: A retrospective review of medical records. SUBJECTS AND SETTING: Data were collected from medical records including official PI records and PI incident reports of inpatients at a teaching hospital in Taiwan between January 2019 and October 2020. METHODS: We collected demographic variables of the inpatients and their hematologic and serum biochemical values within 1 day of PI occurrence (including the day of PI occurrence), 6 to 7 days before PI occurrence, and 13 to 14 days before PI occurrence. RESULTS: Among the 309 inpatients with official PI records, 105 (34.0%) had Stage 1 PIs, 131 (42.4%) had Stage 2 or 3 PIs, and 73 (23.6%) had unstageable or suspected deep tissue injuries. After controlling for the type of department where PIs occurred and length of hospital stay up to the day of PI occurrence, we found significant differences in levels of hemoglobin (odds ratio [OR] = 0.47, P = .009) within 1 day of PI occurrence and in albumin (OR = 0.30, P = .001) 13 to 14 days before PI occurrence. CONCLUSIONS: Study findings suggest that lower hemoglobin levels on the day of PI occurrence and lower albumin levels 2 weeks before PI occurrence resulted in a significantly higher risk of developing unstageable or suspected deep tissue injuries than of developing Stage 1 PIs.

Comparative analysis of pressure ulcer development in stroke patients within and outside healthcare facilities: A systematic review and meta-analysis.

The risk of pressure ulcers in stroke patients is a significant concern, impacting their recovery and quality of life. This systematic review and meta-analysis investigate the prevalence and risk factors of pressure ulcers in stroke patients, comparing those in healthcare facilities with those in home-based or non-clinical environments. The study aims to elucidate how different care settings affect the development of pressure ulcers, serving as a crucial indicator of patient care quality and management across diverse healthcare contexts. Following PRISMA guidelines, a comprehensive search was conducted across PubMed, Embase, Web of Science and the Cochrane Library. Inclusion criteria encompassed studies on stroke patients in various settings, reporting on the incidence or prevalence of pressure ulcers. Exclusion criteria included non-stroke patients, non-original research and studies with incomplete data. The Newcastle-Ottawa scale was used for quality assessment, and statistical analyses involved both fixed-effect and random-effects models, depending on the heterogeneity observed. A total of 1542 articles were initially identified, with 11 studies meeting the inclusion criteria. The studies exhibited significant heterogeneity, necessitating the use of a random-effects model. The pooled prevalence of pressure injuries was 9.53% in patients without family medical services and 2.64% in patients with medical services. Sensitivity analysis confirmed the stability of these results, and no significant publication bias was detected through funnel plot analysis and Egger's linear regression test. The meta-analysis underscores the heightened risk of pressure injuries in stroke patients, especially post-discharge. It calls for concerted efforts among healthcare providers, policymakers and caregivers to implement targeted strategies tailored to the specific needs of different care environments. Future research should focus on developing and evaluating interventions to effectively integrate into routine care and reduce the incidence of pressure injuries in stroke patients.

A nomogram to predict the risk of surgery-related pressure ulcers in patients undergoing cardiovascular surgery.

OBJECTIVE: In this study, we aimed to establish a new nomogram score to predict the occurrence of surgery-related pressure ulcers (SRPU) in patients undergoing cardiovascular surgery. METHODS: We conducted a retrospective study among patients who underwent cardiovascular surgery between February 2016 and November 2020. RESULTS: We established a prediction model based on a logistic regression model and tested the calibration and discrimination. We included 1163 patients who had undergone cardiovascular surgery. We formulated the logistic regression model, with Logit(P) = -11.745 + 0.024 preoperative hemoglobin value + 0.118 serum sodium value - 0.014 prealbumin value - 0.213 intraoperative mean temperature - 0.058 minimum mean arterial pressure + 0.646 preoperative blood potassium value + 0.264 smoking frequency + 0.760 hypertension history + 0.536 age ≥70 years. In this model ,"+" indicates that the factor is positively related to the occurrence risk of SRPU and "-" indicates that the factor is negatively associated with SRPU risk. The predictive model and nomogram had good accuracy in estimating the risk of SRPU, with a C-index of 0.755 (95% confidence interval: 0.719-0.792). CONCLUSIONS: The present model can be used to effectively screen patients with a high risk of SRPU to devise targeted nursing intervention strategies and ultimately reduce the incidence rate of SRPU.

Trends in pressure injury prevalence rates and average days to healing associated with adoption of a comprehensive wound care program and technology in skilled nursing facilities in the United States.

INTRODUCTION: A large SNF system in the United States adopted a holistic wound care model that included an AI DWMS to improve PI care. OBJECTIVE: To compare the trend in PI point prevalence rates and average days to healing linked to adopting technology in practice from 2021 to 2022, and to assess the rate of received PI F686 citations in facilities that adopted the technology compared with those that did not. METHODS: The study used the DWMS database to compare anonymized PI data assessed in 2021 (15 583 patients) vs 2022 (30 657 patients) from all SNF facilities that adopted the technology in 2021 and 2022. F686 citations data were provided by the SNF organization. RESULTS: There was a 13.1% reduction in PI prevalence from 2021 to 2022 across all PI stages. Facilities that adopted the technology demonstrated a significant reduction in days to healing from 2021 to 2022, with an average of 17.7 days saved per PI or a 37.4% faster healing rate (P < .001). A significant reduction in the average days to healing was noted for all PI stages, with the most significant savings observed for stages 3 and 4, with an average savings of 35 days (stage 3) and 85 days (stage 4) in 2022 vs 2021 (P < .001). From 2021 to 2022, facilities that adopted the technology reported an overall 8.2% reduction in F-686 citations severity >G compared to those that did not adopt the technology. CONCLUSION: Use of technology as part of a comprehensive wound care program has the potential to not only improve patient care and quality of life, but to realize considerable annual savings in additional PI out-of-pocket expenses (up to $1 410 000) and of clinicians' time (44 808 hours).

The occurrence of pressure injuries and related risk factors in patients undergoing extracorporeal membrane oxygenation for respiratory failure: A retrospective single centre study.

INTRODUCTION: Limited data is available regarding the incidence of pressure injuries in patients who have undergone Extracorporeal Membrane Oxygenation (ECMO), a life-saving technique that provides respiratory support for hypoxemia that does not respond to conventional treatment. AIM: To assess the incidence of pressure injuries and identify the risk factors in Acute Respiratory Distress Syndrome patients receiving ECMO. METHODS: A retrospective observational study utilizing prospectively collected data was performed in an Italian intensive care unit, between 1 January 2012 and 30 April 2022 enrolling all consecutive patients with Acute Respiratory Distress Syndrome who underwent ECMO. RESULTS: One hundred patients were included in this study. 67 patients (67%) developed pressure injuries during their intensive care unit stay, with a median of 2 (1-3) sites affected. The subgroup of patients with pressure injuries was more hypoxic before ECMO implementation, received more frequent continuous renal replacement therapy and prone positioning, and showed prolonged ECMO duration, intensive care unit and hospital length of stay compared to patients without pressure injuries. The logistic model demonstrated an independent association between the pO2/FiO2 ratio prior to ECMO initiation, the utilization of the prone positioning during ECMO, and the occurrence of pressure injuries. CONCLUSIONS: The incidence of pressure injuries was elevated in patients with Adult Respiratory Distress Syndrome who received ECMO. The development of pressure injuries was found to be independently associated with hypoxemia before ECMO initiation and the utilization of prone positioning during ECMO. IMPLICATIONS FOR CLINICAL PRACTICE: Patients who require ECMO for respiratory failure are at a high risk of developing pressure injuries. To ensure optimal outcomes during ECMO implementation and treatment, it is vital to implement preventive measures and to closely monitor skin health in at-risk areas.

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

BACKGROUND: Pressure injury is a severe problem that can significantly impact a patient's health, quality of life, and healthcare expenses. The prevalence of pressure injuries is a widely used clinical indicator of patient safety and quality of care. This study aims to address the research gap that exists on this topic in Kuwait by investigating the prevalence of pressure injuries and preventive measures on the medical wards of the country's public general hospitals. METHODS: A cross-sectional research design was adopted to measure the point prevalence of pressure injuries on 54 medical wards in the public general hospitals. Data, including variables pertaining to hospitals, patients, pressure injuries and preventive practices, were collected using an online form. The data were processed and analysed using Microsoft Excel and SPSS 23 (α level = 0.05). Analysis provided an overview of patient, pressure injury characteristics and preventive measures, and the relationships between the patient and pressure injury characteristics and the prevalence of pressure injuries. A model for predicting the determinants of pressure injury prevalence was constructed from a linear regression analysis. RESULTS: The mean national prevalence of pressure injury was 17.6% (95% CI: 11.3-23.8). Purely community-acquired pressure injuries represent the majority of pressure injuries nationally (58.1%). Regarding preventive measures, "pressure injury assessment on admission" has been provided to 65.5% of patients. Correlation analysis revealed that the only statistically significant correlation with the prevalence of hospital-acquired pressure injury was "pressure injury assessment on admission", which was strongly negative (ρ = -0.857). Therefore, this was the only variable included in the regression analysis as a predictor of pressure injury prevalence (Beta = 0.839). The results showed many statistically significant differences between hospitals with respect to the variables studied. CONCLUSIONS: The national pressure injury prevalence is high compared to the global rate. The higher percentage of purely community-acquired pressure injuries requires particular attention. Many risk factors for the development of pressure injuries are public health concerns, and effective mitigating strategies are needed. Further research is required to assess the knowledge, attitude, and behaviour of nurses with respect to pressure injuries, and to evaluate preventive and management practices.
