Explore the effect of pressure and time of compression on the risk of intraoperatively acquired pressure injury based on theoretical framework: A prospective study.

Surgery is a high risk factor for the occurrence of pressure injury (PI). On the basis of theoretical research, pressure and duration of pressure are key factors affecting PI. Pressure is affected by the individual pressure redistribution capacity. So our study aims to explore how the surgery time and pressure intensity affect the occurrence of PI and what are the risk factors. A prospective study. A total of 250 patients who underwent elective surgery in a grade-A general hospital from November 2021 to February 2023 were selected and divided into a group of 77 patients with IAPI (intraoperatively acquired pressure injury) and a group of 173 patients with no IAPI. Visual pressure inductive feedback system and body composition analysis technology were used to record the local pressure value and change of patients before and after anaesthesia. Relevant data of the patients were collected to explore the influencing factors. The maximum pressure and average pressure at the pressure site of the same patient changed before and after anaesthesia, and the pressure after anaesthesia was significantly higher than that before anaesthesia. There was no statistical difference in the average pressure after anaesthesia (p > 0.05), but the maximum pressure in the IAPI group was higher than that in the non-occurrence group (p < 0.05). The average pressure multiplied by the operation time in IAPI group is significantly higher than that in the non-IAPI group (p < 0.01). Multiple linear regression analysis (stepwise regression) showed that fat-free weight, age, waist circumference, body mass index (BMI) and gender were taken as independent variables into the regression model, affecting the maximum pressure. In addition, operation time ≥4 h may be a high risk factor for IAPI. In future studies, more objective research tools can be applied to improve the accuracy of predicting the risk of IAPI. In addition to gender and BMI, follow-up studies may consider including measures such as waist circumference and fat-free body weight in IAPI risk assessment to guide the clinical nursing work more scientifically.

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.

Role of nutritional support in nursing practice for improving surgical site wound healing in patients post-surgery with risk of pressure ulcers.

To explore the role of nutritional support in nursing practice on postoperative surgical site wound healing in patients undergoing surgery at risk for pressure ulcers. This study adopted a retrospective experimental design and included a total of 60 patients at risk of pressure ulcers, divided into a nutritional support group and a control group, with 30 people in each group. The nutritional support group implemented specific nutritional support measures after surgery, while the control group received standard postoperative care. Outcome measures included redness and swelling scores, edema scores, anxiety assessments, pain scores, bleeding volume, recovery time and incidence of pressure ulcers. The result indicates that patients who received nutritional support exhibited lower postoperative wound redness and swelling scores compared to the control group (3.11 ± 0.45 vs. 4.85 ± 0.74, p < 0.05). Additionally, the nutritional support group showed significantly lower edema scores (2.75 ± 0.37 vs. 3.53 ± 0.62, p < 0.05). Anxiety levels, as measured by the anxiety assessment scale (SAS), were also lower in the nutritional support group (6.52 ± 1.19 vs. 7.60 ± 1.62, p < 0.05). Moreover, the average healing time was shorter for the nutritional support group (7.27 ± 1.36 days) compared to the control group (9.71 ± 1.84 days, p < 0.05). Postoperative pain scores were lower in the nutritional support group (4.13 ± 0.72 vs. 5.43 ± 0.62, p < 0.05), and patient satisfaction scores were higher (9.42 ± 0.76 vs. 7.25 ± 0.81, p < 0.05). Nutritional support has a positive effect on postoperative wound healing at surgical sites in patients at risk of pressure ulcers in nursing practice. It can significantly reduce redness, swelling, edema, anxiety, and pain scores, reduce bleeding, shorten recovery time, and reduce pressure ulcers. incidence rate.

Impact of shear stress on sacral pressure injury from table rotation during laparoscopic colorectal surgery performed in the lithotomy position.

This study aimed to evaluate the impact of shear stress on surgery-related sacral pressure injury (PI) after laparoscopic colorectal surgery performed in the lithotomy position. We included 37 patients who underwent this procedure between November 2021 and October 2022. The primary outcome was average horizontal shear stress caused by the rotation of the operating table during the operation, and the secondary outcome was interface pressure over time. Sensors were used to measure shear stress and interface pressure in the sacral region. Patients were divided into two groups according to the presence or absence of PI. PI had an incidence of 32.4%, and the primary outcome, average horizontal shear stress, was significantly higher in the PI group than in the no-PI group. The interface pressure increased over time in both groups. At 120 min, the interface pressure was two times higher in the PI group than in the no-PI group (PI group, 221.5 mmHg; no-PI group, 86.0 mmHg; p < 0.01). This study suggested that shear stress resulting from rotation of the operating table in the sacral region by laparoscopic colorectal surgery performed in the lithotomy position is the cause of PI. These results should contribute to the prevention of PI.

A rare presentation of Rosai-Dorfman-Destombes disease with central nervous system involvement and cutaneous wounds.

OBJECTIVE: The aim of this case report is to investigate an uncommon presentation of Rosai-Dorfman-Destombes (RDD) disease, and discuss possible differential diagnoses and treatment options for this pathology. RDD is a rare disorder of histiocytes that typically presents in patients as painless cervical lymphadenopathy. However, this case involves a patient with the central nervous system (CNS) type of RDD who later developed cutaneous lesions. METHOD: Several differential diagnoses were examined, including hidradenitis suppurativa, pilonidal cyst and pressure ulcers. It is important to be able to exclude these diagnoses based on the presentation, patient demographic and wound location. RESULTS: Biopsies verified the presence of RDD in the patient's suprasellar hypothalamic mass and skin lesions, confirming the patient had both CNS-RDD and cutaneous-RDD in the absence of lymphadenopathy. CONCLUSION: Recognising the unique manifestations of rare diseases such as RDD prevents delay of proper intervention and treatment.

Risk Factors of Intraoperative Pressure Injury in Adult Patients Undergoing Neurologic Surgery.

GENERAL PURPOSE: To present research investigating the incidence of and risk factors associated with intraoperative pressure injury in patients undergoing neurologic surgery at Xiangya Hospital, Central South University in China. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Identify the incidence of intraoperative pressure injuries (PIs) in patients undergoing neurologic surgery at Xiangya Hospital, Central South University in China.2. Describe risk factors for intraoperative PI.3. Outline strategies to help mitigate intraoperative PI risk.

Intraoperative pressure injury (PI) development is an adverse event that impacts thousands of patients globally and is associated with extended hospital stays and increased risk of mortality. To investigate the incidence of intraoperative PI in patients undergoing neurologic surgery and identify associated risk factors. A total of 1,728 patients who underwent neurosurgery in Xiangya Hospital, Central South University between January 2021 and December 2022 were included in this retrospective study. The authors collected patients' demographic data and clinical characteristics and used univariate and multivariate regression to evaluate significant PI risk factors. Intraoperative PI was observed in 1.8% of all surgical cases (n = 31). Having a body mass index greater than 24 kg/m2 (odds ratio, 3.87; 95% CI, 1.62­9.23; P = .002), being in a lateral position (odds ratio, 2.53; 95% CI, 1.04­6.17; P = .042) or a prone position (odds ratio, 10.43; 95% CI, 3.37­32.23; P < .001), and having a longer operation time (cutoff point at 7.92 hours for increased risk of PI; odds ratio, 1.36; 95% CI, 1.21­1.53; P < .001) were significant risk factors for intraoperative PI. This study identified three independent risk factors for intraoperative PI development: body position, surgery duration, and high body mass index. These findings can help OR nurses identify patients who are vulnerable to intraoperative PI and provide appropriate preventive measures. For these patients, perioperative protection and frequent microrepositioning during surgery would be indispensable.

Pressure ulcers acquired during inpatient rehabilitation after spinal cord injury, characterization and predictors: A 15-years' experience.

BACKGROUND: Most studies focus on the risk factors associated with the development of pressure ulcers (PUs) during acute phase or community care for individuals with spinal cord injury (SCI). OBJECTIVES: This study aimed to i) compare clinical and demographic characteristics of inpatients after SCI with PUs acquired during rehabilitation vs inpatients without PUs and ii) evaluate an existing PU risk assessment tool iii) identify first PU predictors. METHODS: Individuals (n = 1,135) admitted between 2008 and 2022 to a rehabilitation institution within 60 days after SCI were included. Admission Functional Independence Measure (FIM), American Spinal Injury Association Impairment Scale (AIS) and mEntal state, Mobility, Incontinence, Nutrition, Activity (EMINA) were assessed. Kaplan-Meier curves and Cox proportional hazards models were fitted. RESULTS: Overall incidence of PUs was 8.9%. Of these, 40.6% occurred in the first 30 days, 47.5% were sacral, 66.3% were Stage II. Patients with PUs were older, mostly with traumatic injuries (67.3%), AIS A (54.5%), lower FIM motor (mFIM) score and mechanical ventilation. We identified specific mFIM items to increase EMINA specificity. Adjusted Cox model yielded sex (male), age at injury, AIS grade, mFIM and diabetes as PUs predictors (C-Index = 0.749). CONCLUSION: Inpatients can benefit from combined assessments (EMINA + mFIM) and clinical features scarcely addressed in previous studies to prevent PUs.

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.

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.

[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.

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.

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 predictive nursing interventions on pressure ulcer in elderly bedridden patients.

The study explores the impact of predictive nursing interventions on pressure ulcers (PUs) in elderly bedridden patients. A total of 120 elderly bedridden patients from the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture between August 2019 and August 2023 were selected as the subjects of the study and were randomly divided into an observation group and a control group using a random number table method. The control group received conventional nursing care, while the observation group received predictive nursing interventions. The study compared the incidence of PUs, Braden scale scores, the onset time of PUs, self-rating anxiety scale (SAS) scores, self-rating depression scale (SDS) scores, and nursing satisfaction between the two groups. In elderly bedridden patients, the application of predictive nursing interventions significantly reduced the incidence of PUs (p < 0.001), significantly lowered the SAS and SDS scores (p < 0.001), and also significantly increased Braden scale scores (p < 0.001) and delayed the onset time of PUs (p < 0.001). Additionally, it improved patients' nursing satisfaction (p = 0.008). Predictive nursing interventions in elderly bedridden patients have good application effects, reducing the occurrence of PUs, delaying the time of onset in patients, improving patients' negative emotions and enhancing nursing satisfaction rates. It is worthy of widespread use.

Overlooked Pain Assessment Records in Patients with Pressure Injuries During the COVID-19 Pandemic: A Retrospective Data Analysis.

BACKGROUND: During the COVID-19 pandemic, healthcare professionals focused on identifying the cause of hemodynamic instability in patients and may have neglected to assess pressure injury (PI)-related pain. Although pain is an early indicator of PI development, there has been no systematic evaluation of PI-related pain in patients. OBJECTIVE: To review nurses' records of PI-related pain in patients who developed PIs during the COVID-19 pandemic. METHODS: This retrospective, descriptive study included data from 510 patients at one hospital. Collected data included patient demographics (age, sex, diagnosis, and comorbidities), PI classification, and assessment of PI-related pain. Assessment data regarding PI-related pain included the characteristics of the pain, the type of analgesia (pharmacologic/nonpharmacologic) administered before and after PI management (debridement, dressing change, etc), the route of administration, and the frequency of pain assessment before and after analgesia. RESULTS: The mean age of the patients (60.4% men) was 28.96 (SD, 5.82) years, and the mean length of hospital stay was 26.15 (SD, 16.1) days. Overall, 43.1% of the patients were treated in the ICU, 68.0% were conscious, and 18.6% tested positive for COVID-19. Deep-tissue injuries occurred in 57.5% of patients, with 48.6% developing stage 2 PI. The sacral region was the most common area for PI development (44.8%). The mean duration of repositioning in patients with PI was 23.03 (SD, 5.4) hours. Only 0.40% of patients (n = 2) were evaluated for pain, and only one patient was assessed for pain before and after analgesia was administered. CONCLUSIONS: The findings suggest a lack of comprehensive evaluation and records concerning PI-related pain in patients with COVID-19.

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.

Operative Positioning and Intraoperative-Acquired Pressure Injury: A Retrospective Cohort Study.

OBJECTIVE: To comprehensively assess the association between operative positioning with intraoperative-acquired pressure injury (IAPI) development. METHODS: This retrospective cohort study included 455 patients who underwent surgery between October 2020 and January 2021. The authors grouped patients by operative positioning into the prone position and nonprone position groups. They used propensity-score matching at a 1:2 ratio to control for preoperative confounders, applied multiple logistic regression models to analyze the effects between positioning and IAPI, and assessed interactions of positioning and intraoperative factors on IAPI. RESULTS: The final enrollment was 92 cases in the prone position group and 181 in the nonprone position group. Multivariable logistic analysis suggested that the prone position had a 2.92 times higher risk of IAPI than the nonprone position (odds ratio, 2.92; 95% CI, 1.13-7.57; P = .026). Subgroup analysis showed a significant multiplicative interaction between positioning and foam dressing on IAPI (P < .05), which was not observed in other intraoperative factors (P > .05). CONCLUSIONS: This study provides evidence that prone operative positioning can increase IAPI risk. Patients in the prone position may particularly benefit from using dressings in Chinese populations. Further large-sample longitudinal studies are required to confirm these findings.

Evaluating the Effectiveness of Brief Training for Neonatal Intensive Care Nurses on the Prevention of Medical Device-Related Nasal Pressure Injury.

OBJECTIVE: To evaluate the effectiveness of a brief training in medical device-related pressure injury (MDRPI) prevention for neonatal intensive care nurses. METHODS: This single-group, pretest-posttest quasi-experimental study was conducted between April and October 2021 with 81 nurses working in the neonatal ICU of a city hospital. The participants completed a training program consisting of two 40-minute sessions that used a small-group problem-based learning approach developed in accordance with evidence-based research. Data were collected using a neonatal nurse information form, knowledge of MDRPI in preterm infants form, and training evaluation form, all of which were prepared for this study based on the literature. Data collection was performed before the training and repeated at 1 week and 1 month after the training. Data analysis was performed using the Number Cruncher Statistical System. Descriptive statistics, the Shapiro-Wilk test, Mann-Whitney U test, and Spearman correlation analysis were used. RESULTS: The participants' mean score on the knowledge of MDRPI in premature infants form was 82.44 ± 7.26 before training and increased significantly to 94.57 ± 5.03 at 1 week and 94.67 ± 3.11 at 1 month after training (P = .001 and P = .001, respectively). No significant relationship was detected between the participants' descriptive characteristics and their knowledge scores before or after the training (P > .05). CONCLUSIONS: Brief training on the prevention of nasal pressure injury caused by noninvasive ventilation increased nurses' knowledge level.

Determination of Incidence and Risk Factors of Medical Device-Related Pressure Injury in the ICU: A Descriptive Study.

OBJECTIVE: To determine the incidence and risk factors of medical device-related pressure injury (MDRPI) in the ICU. METHODS: In this descriptive study, the researchers collected data through systematic observation of patients (n = 58) in the ICU. The patients were evaluated within 24 hours of ICU admission and then followed up until they were discharged. A total of 482 patient-days were followed. The researchers used the MDRPI follow-up form, the patient descriptive form, the MDRPI follow-up form, and the Braden Scale for Predicting Pressure Sore Risk for data collection. RESULTS: Overall, 39.7% of the 58 patients hospitalized in the ICU developed an MDRPI, and 5.2% of the MDRPIs were evaluated as stage 2. These injuries occurred in an average of 5 days after the patient was admitted to the ICU. Among the MDRPIs that developed, 31.9% were located in the nose, 21.3% in the mouth, and 14.9% on the cheeks. Intubation tubes were used in 7.3% of the patients, nasogastric tubes in 22.4% of the patients, and radial artery catheters in 10.5% of the patients. CONCLUSIONS: The development of MDRPI is correlated with the type of medical device used. Providers should establish a planned care protocol based on the anatomic placement of the medical device and take necessary precautions to prevent MDRPI.

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.
