Abstract
AIMS To determine the risk of pressure injury development in the intensive care unit based on changes in patient conditions. DESIGN This retrospective study was based on secondary data analysis. METHODS Patient data from electronic health records were retrospectively obtained and we included 438 and 1752 patients with and without pressure injury, respectively, among those admitted to the medical and surgical intensive care units (ICUs) from January 2017-February 2020. Changes in patient conditions were analysed based on the first and last objective data values from the day of ICU admission to the day before the onset of pressure injury and categorised as follows: improved, maintained normal, exacerbated and unchanged. Logistic regression was performed to identify the significant predictors of pressure injury development based on 11 variables. RESULTS The 11 selected variables were age, body mass index, activity, acute physiology and chronic health evaluation II score, nursing severity level, pulse and albumin, haematocrit, C-reactive protein, total bilirubin and blood urea nitrogen levels. The risk for a pressure injury was high with exacerbation of or persistently abnormal levels of nursing severity, albumin, haematocrit, C-reactive protein, blood urea nitrogen and pulse >100 beat/min. CONCLUSION Periodic monitoring of haematological variables is important for preventing pressure injury in the intensive care unit. REPORTING METHOD The study followed STROBE guidelines. PATIENT OR PUBLIC CONTRIBUTION This study contributes to the utilisation of patient data from electronic health records. RELEVANCE TO CLINICAL PRACTICE In addition to other pressure injury risk assessment tools, ICU nurses can help prevent pressure injuries by assessing patients' blood test results, thereby promoting patient safety and enhancing the efficacy of nursing practice.

The prediction model for intraoperatively acquired pressure injuries in orthopedics based on the new risk factors: a real-world prospective observational, cross-sectional study. Front Physiol 2023; 14:1170564. [PMID: 37546531 PMCID: PMC10401272 DOI: 10.3389/fphys.2023.1170564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 07/05/2023] [Indexed: 08/08/2023] Open
Abstract
Introduction: Orthopedic patients are at high risk for intraoperatively acquired pressure injuries (IAPI), which cause a serious issue and lead to high-expense burden in patient care. However, there are currently no clinically available scales or models to assess IAPI associated with orthopedic surgery. Methods: In this real-world, prospective observational, cross-sectional study, we identified pressure injuries (PI)-related risk factors using a systematic review approach and clinical practice experience. We then prepared a real-world cohort to identify and confirm risk factors using multiple modalities. We successfully identified new risk factors while constructing a predictive model for PI in orthopedic surgery. Results: We included 28 orthopedic intraoperative PI risk factors from previous studies and clinical practice. A total of 422 real-world cases were also included, and three independent risk factors-preoperative limb activity, intraoperative wetting of the compressed tissue, and duration of surgery-were successfully identified using chi-squared tests and logistic regression. Finally, the three independent risk factors were successfully used to construct a nomogram clinical prediction model with good predictive validity (area under the ROC curve = 0.77), which is expected to benefit clinical patients. Conclusion: In conclusion, we successfully identified new independent risk factors for IAPI-related injury in orthopedic patients and developed a clinical prediction model to serve as an important complement to existing scales and provide additional benefits to patients. Our study also suggests that a single measure is not sufficient for the prevention of IAPI in orthopedic surgery patients and that a combination of measures may be required for the effective prevention of IAPI.

Abstract
PURPOSE The purpose of this study was to measure the incidence of suspected deep tissue pressure injuries (DTPIs) in patients admitted to the hospital, describe their location, identify the related hospital length of stay, and explore any associations between intrinsic or extrinsic factors relevant to DTPI development. DESIGN Retrospective review/audit of clinical data. SUBJECTS AND SETTING We reviewed pertinent medical data from patients reported as developing a suspected deep tissue injury during hospital admission from January 2018 to March 2020. The study setting was a large tertiary public health service in Victoria, Australia. METHODS Patients who developed a suspected deep tissue injury during hospital admission between January 2018 and March 2020 were identified through the hospital online risk recording system. Data were extracted from the relevant health records, including demographics, admission data, and pressure injury data. The incidence rate was expressed per 1000 patient admissions. Multiple regression analyses were used to determine associations between the time (days) to develop a suspected deep tissue injury and intrinsic (patient level) or extrinsic (hospital level) factors. RESULTS Six hundred fifty-one pressure injuries were recorded during the audit period. A minority (9.5%; n = 62) of patients developed a suspected deep tissue injury; all were located on the foot and ankle. The incidence of suspected deep tissue injuries was 0.18 per 1000 patient admissions. The mean length of stay among patients who developed a DTPI was 59.0 (SD = 51.9) days as compared to a mean of 4.2 (SD = 11.8) days for all patients admitted to the hospital during this period. Multivariate regression analysis determined that the longer time (in days) to develop a pressure injury was associated with having a higher body weight (Coef = 0.02; 95% CI = 0.00 to 0.04; P = .043), not having off-loading (Coef =-3.63; 95% CI =-6.99 to -0.27; P = .034), and an increasing number of ward transfers (Coef = 0.46; 95% CI = 0.20 to 0.72; P = .001). CONCLUSIONS Findings identified factors that may play a role in the development of suspected deep tissue injuries. A review of risk stratification in health services may be beneficial, with consideration to adjustments of procedural assessments of patients at risk.

Abstract
BACKGROUND Patients who have undergone vascular operations are thought to be at an increased risk for developing pressure injuries; however, the extent to which pressure injuries occur in this population is not clear. This scoping review sought to summarize what is known about the incidence of pressure injuries, and the risk factors for the development of pressure injuries in patients who have undergone vascular operations. MAIN: An initial search identified 2564 articles, and 9 English language studies were included. Results showed that due to study design limitations in the available literature preventing hospital-acquired and present on admission pressure injuries to be distinguished, it is difficult to ascertain the incidence rate of pressure injuries in this population. CONCLUSION Certain vascular procedures were found to be higher risk for the development of pressure injuries such as major amputations and lower extremity bypass surgery. In addition to procedural risk factors, patient factors were identified that may be associated with the development of pressure injuries in the vascular population, and these in the authors' view deserve further exploration. Overall, this scoping review identified an area ripe for future research, the results of which would have implications for wound care in healthcare institutions and at home.

Abstract
Pressure injuries, also known as pressure ulcers, are regions of localized damage to the skin and/or underlying tissue. Repeated rounds of ischemia-reperfusion (I/R) have a major causative role for tissue damage in pressure injury. Ischemia prevents oxygen/nutrient supply, and restoration of blood flow induces a burst of reactive oxygen species that damages blood vessels, surrounding tissues and can halt blood flow return. Minimizing the consequences of repeated I/R is expected to provide a protective effect against pressure injury. Sulfaphenazole (SP), an off patent sulfonamide antibiotic, is a potent CYP 2C6 and CYP 2C9 inhibitor, functioning to decrease post-ischemic vascular dysfunction and increase blood flow. The therapeutic effect of SP on pressure injury was therefore investigated in apolipoprotein E knockout mice, a model of aging susceptible to ischemic injury, which were subjected to repeated rounds of I/R-induced skin injury. SP reduced overall severity, improved wound closure and increased wound tensile strength compared to vehicle-treated controls. Saliently, SP restored tissue perfusion in and around the wound rapidly to pre-injury levels, decreased tissue hypoxia, and reduced both inflammation and fibrosis. SP also demonstrated bactericidal activity through enhanced M1 macrophage activity. The efficacy of SP in reducing thermal injury severity was also demonstrated. SP is therefore a potential therapeutic option for pressure injury and other ischemic skin injuries.

Abstract
Pressure injuries (PIs), also known as bedsores or pressure ulcers, are a major cause of death and morbidity in the elderly. The serine protease, Granzyme B (GzmB), contributes to skin aging and impaired wound healing. Aging is a major risk factor for PIs; thus, the role of GzmB in PI pathogenesis was investigated. GzmB levels in human PI tissue and wound fluids were markedly elevated. A causative role for GzmB was assessed in GzmB knockout (GzmB−/−) and wild-type (WT) mice using a murine model of PI. An apolipoprotein E knockout (ApoE−/−) model of aging and vascular dysfunction was also utilized to assess GzmB in a relevant age-related model better resembling tissue perfusion in the elderly. PI severity displayed no difference between young GzmB−/− and WT mice. However, in aged mice, PI severity was reduced in mice lacking GzmB. Mechanistically, GzmB increased vascular wall inflammation and impaired extracellular matrix remodeling. Together, GzmB is an important contributor to age-dependent impaired PI healing.

Abstract
AIMS We sought to explore factors associated with early pressure injury progression and build a model for predicting these outcomes using a machine learning approach. DESIGN A retrospective cohort study. METHODS In this study, we recruited paediatric patients, with hospital-acquired stage I pressure injury or suspected deep tissue injury, who met the inclusion criteria between 1 January 2015-31 October 2018. We divided patients into two groups, namely healing or delayed healing, then followed them up for 7 days. We analysed patient pressure injury characteristics, demographics, treatment, clinical situation, vital signs, and blood test results, then build prediction models using the Random Forest and eXtreme Gradient Boosting approaches. RESULTS The best prediction model, trained and tested using Random Forest with 10 variables, achieved an accuracy, sensitivity, specificity, and area under the curve of 0.82 (SD 0.06), 0.80 (SD 0.08), 0.84 (SD 0.08), and 0.89 (SD 0.06), respectively. The most contributing variables, in order of importance, included serum creatinine, red blood cell, and haematocrit. CONCLUSION An awareness of specific conditions and areas that could lead to delayed healing pressure injury in paediatric patients is needed. IMPACT This evidence-based prediction model, coupled with the aforementioned clinical indicators, is expected to enhance early prediction of outcomes in paediatric patients thereby improve the quality of care and the outcome of children with PIs.

Abstract
Background Pressure ulcers (PUs) are one of the quality care indicators in nursing care. They are considered to primarily be preventable. Early identification of the patients most at risk particular for critically ill patients is crucial for providing prompt care. Several tools have been developed to support healthcare providers, but their validities are limited in Thailand. Development of tools with better performance is essential. Aims To develop and validate a PU risk assessment tool with good diagnostic properties in intensive care units (ICUs). Methods A prospective study was conducted in ICUs of a tertiary care hospital, Thailand from January 2019 to April 2020. Baseline data were collected at admission to the ICUs. Skin assessment was evaluated every 24 h. Data were divided into two sets: model development and model validation. Creating a risk score which was derived from multivariate methods were performed. Youden index were used to determine the optimal cut-off point. Then, the other dataset was used to validate the risk score. Receiver Operating Characteristic (ROC) curves was used to demonstrate the performance of the test. Results The study included 288 and 270 patients for development and validation models. The risk score consisted 4 clinical factors; presence of Cardiovascular disease, low serum Albumin, having Ventilated, and Edema (CAVE score). The area under the ROC curve (AUC) was 0.8 and a score at 2.5 was the best cut-off point. The AUC in the validation group was 0.6, age<60 years was 0.78, and age≥60 years was 0.57. Conclusion The predictive validity of the CAVE score is limited but comparable to the existing tools in Thailand. However, it has a good diagnostic property in young patients. The CAVE score could be considered as an alternate screening tool in critical care setting particularly for young patients.

What is the frequency of pressure injury in vascular patients undergoing major amputations? JOURNAL OF VASCULAR NURSING 2020; 38:72-75. [PMID: 32534656 DOI: 10.1016/j.jvn.2020.02.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2019] [Revised: 02/17/2020] [Accepted: 02/19/2020] [Indexed: 11/22/2022]
Abstract
Individuals with peripheral arterial disease who have undergone below or above knee amputations have limited mobility and may sit for long periods of time in a wheelchair, increasing their risk for pressure injury. The aim of this descriptive cross-sectional research study was to retrospectively review the charts of those patients with peripheral arterial disease undergoing lower limb amputations from 2016 to 2017 at a major academic medical center to determine the frequency of pressure injury. Hospital data were used to identify patients discharged from 2016 to 2017 with primary International Classification of Diseases (10th Revision) codes for below knee amputations/above knee amputations and pressure injury (ulcer). From 2016 to 2017, 46 patients were admitted to the inpatient vascular surgery service for a below or above knee amputation. Seventeen of those patients had documented pressure injuries at hospital discharge for a frequency of 37%. There were 11 males and 6 females with age range of 44 to 82 years with a mean age of 66 years. There was a total of 19 pressure injuries (2 patients had 2 pressure injuries). Ten of those 19 pressure injuries were present on admission to the hospital and 9 pressure injuries were hospital-acquired pressure injuries. Thirteen of the 19 pressure injuries (68%) were on the sacrum. Three of the pressure injuries (16%) were on the heel. Two (11%) were ischial pressure injuries with one knee (5%) pressure injury. Risk assessment is an essential part of vascular nursing practice that aims to identify individuals at risk for pressure injury with appropriate interventions to prevent their occurrence. Vascular nurses should be encouraged to educate patients/family members on the increased risk of pressure injuries in those undergoing amputation during hospitalization and after discharge to prevent them from occurring.

Abstract
BACKGROUND Despite decades of research, pressure injuries continue to be a source of significant pain and delayed recovery for patients and substantial quality and cost issues for hospitals. Consideration of the current thinking around pressure injury risk must be evaluated to improve risk assessments and subsequent nursing interventions aimed at reducing hospital-acquired pressure injuries. DESIGN This is a discursive paper using Walker and Avant's (2005) theory synthesis framework to examine the relevance of existing pressure injury models as they align with the current literature. METHODS PubMed and CINAHL indexes were searched, first for conceptual models and then for pressure injury research conducted on hospitalised patients for the years 2006-2016. A synthesis of the searches culminated into a new pressure injury risk model. CONCLUSIONS Gaps in previous models include lack of attention to the environment, contributing episode-of-care factors and the dynamic nature of injury risk for patients. Through theory synthesis, the need for a new model representing the full risk for pressure injury was identified. The Pressure Injury Predictive Model is a representation of the complex and dynamic nature of pressure injury risk that builds on previous models and addresses new patient, contextual and episode-of-care process influences. The Pressure Injury Predictive Model (PIPM) provides a more accurate picture of the complexity of contextual and process factors associated with pressure injury development. RELEVANCE TO CLINICAL PRACTICE Using the PIPM to determine risk can result in improved risk identification. This information can be used to implement targeted, evidence-based pressure injury prevention interventions specific to the patient risk profile, thus limiting unwarranted and unnecessary care.

Abstract
BACKGROUND Validated perioperative pressure injury (PI) risk assessment measures are few and often cumbersome to complete, leading to missed opportunities to identify and target prevention interventions to those patients at increased risk for developing a postsurgical PI. OBJECTIVES Previous validation of a six-item perioperative risk assessment measure for skin (PRAMS) was conducted in our community hospital with positive findings. The purpose of this study was to increase generalizability by revalidating the PRAMS in a larger sample. METHODS This was a retrospective chart review of all surgical patients aged ≥18 years positioned in the supine or lateral position in a Midwest quaternary care, multispecialty, 1,500-bed hospital during a 6-month period (n = 1,526). The intent of the study was to revalidate the PRAMS. The main outcome of interest was the development of PI after surgery. Risk indicators of interest included diabetes, age, surgical time, Braden score, previous surgery, and preexisting PI. The diagnostic ability of any of the risk indicators on the development of a postsurgical PI was evaluated using sensitivity, specificity, and predictive values. RESULTS Postsurgical PIs occurred in 121 patients. Comparing current to previous study results, the PRAMS was effective in identifying surgical patients at risk for PI (sensitivity = .98). Those patients with a postsurgical PI had a lower mean Braden score, were more likely to have a preexisting PI, and were more likely to have a previous surgery during the same admission (p < .001 for all risk indicators), comparing favorably to the original study. Patients without risk indicators were unlikely to develop a postsurgical PI (negative predictive value = .98). DISCUSSION Results of this validation study demonstrate that the PRAMS is effective in identifying patients who developed a postsurgical PI using information readily available to the perioperative staff.

Abstract
Objectives: to evaluate and classify patients according to the Risk Assessment Scale for Perioperative Pressure Injuries; verify the association between sociodemographic and clinical variables and the risk score; and identify the occurrence of pressure injuries due to surgical positioning. Method: observational, longitudinal, prospective and quantitative study carried out in a teaching hospital with 278 patients submitted to elective surgeries. A sociodemographic and clinical characterization questionnaire and the Risk Assessment Scale for Perioperative Pressure Injuries were used. Descriptive, bivariate and logistic regression analyses were applied. Results: the majority of patients (56.5%) presented a high risk for perioperative pressure injury. Female sex, elderly group, and altered body mass index values were statistically significant (p < 0.05) for a higher risk of pressure injuries. In 77% of the patients, there were perioperative pressure injuries. Conclusion: most of the participants presented a high risk for development of perioperative decubitus ulcers. The female sex, elderly group, and altered body mass index were significant factors for increased risk. The Risk Assessment Scale for Perioperative Pressure Injuries allows the early identification of risk of injury, subsidizing the adoption of preventive strategies to ensure the quality of perioperative care.

Abstract
Background The prevalence of pressure ulcers particularly in the frail older adult population continues to be high and very costly especially in those suffering from chronic diseases and has brought a higher awareness to comprehensive, preventive and therapeutic measures for treatment of pressure ulcers. Internal risk factors highlighted by comorbidities play a crucial role in the pathogenesis of pressure ulcers. Main body Focusing on the impact of common chronic diseases (comorbidities) in aging on pressure ulcers (e.g., cardiovascular diseases, diabetes, chronic pulmonary diseases, renal diseases and neurodegenerative disorders) and the significant complicating conditions e.g., anemia, infectious diseases, malnutrition, hospitalization, incontinence and polypharmacy, frailty and disability becomes important in developing a more complete, inclusive and multidisciplinary approach to prevention of PU in older patients. Objective To describe chronic and acute conditions which are risk factors in elderly patients for developing PU. Methods We present an overview of comorbidities seen with PU in three diverse patient locations. The inclusion criteria are sites (community, acute hospital and long term facilities), older patients, chronic diseases and pressure ulcers grade 2 and over. Using a recently developed conceptual framework accepted by European and National Pressure Ulcer Advisory Panels, we examined chronic diseases to identify the risk factors of chronic conditions and complicating conditions which potentially influence risk for PU development. Conclusion Multiple chronic diseases and complicating factors which associated with immobility, tissue ischemia, and undernutrition are caused to PU in community settings, hospitals, and nursing facilities.

Abstract
PURPOSE This study examined the incidence of oral mucosa pressure ulcers (PUs) in intensive care unit (ICU) patients and the relationship between biomechanical and physiological variables in onset of PUs. METHODS A prospective observational descriptive study design was used. We recruited patients over 18 years of age with endotracheal tube (ETT) insertion in three ICUs in a tertiary hospital in Korea. We analysed 113 patient-days of data. Patient assessments and medical record reviews were conducted to gather biomechanical and physiological data. Fisher's exact tests and χ2 test and Spearman's rank correlations were used to compare data. RESULTS The highest incidence of oral mucosa PUs occurred in lower oral mucosa (36.3%). There was a significant relationship between lower oral mucosa PU stage and bite-block or airway use (r = .20, p = .036), commercial ETT holder use (r = 0.19, p = .048), sedative use (r = -0.22, p = .022), and plasma protein (r = 0.20, p = .033). Upper oral mucosa PU stage was related to commercial ETT holder use (r = 0.19, p = .044), haemoglobin(r = 0.24, p = .011), haematocrit (r = 0.27, p = .004), and serum albumin (r = -0.24, p = .012). Stage was related to commercial ETT holder use in both sites (r = 0.28, p = .003), haematocrit (r = 0.19, p = .039), and serum albumin (r = -0.23, p = .015). CONCLUSION Oral mucosa PUs developed more frequently and healed more quickly than general skin PUs. Taken together, these data indicate that biomechanical and haematological variables are risk factors associated with PU incidence should be considered in intensive care patients.

Abstract
Surgical patients are prone to developing hospital-acquired pressure ulcers (HAPU). Therefore, a better prediction tool is needed to predict risk using preoperative data. This study aimed to determine, from previously published HAPU risk factors, which factors are significant among our surgical population and to develop a prediction tool that identifies pressure ulcer risk before the operation. A literature review was first performed to elicit all the published HAPU risk factors before conducting a retrospective case-control study using medical records. The known HAPU risks were compared between patients with HAPU and without HAPU who underwent operations during the same period (July 2015-December 2016). A total of 80 HAPU cases and 189 controls were analysed. Multivariate logistic regression analyses identified eight significant risk factors: age ≥ 75 years, female gender, American Society of Anaesthesiologists ≥ 3, body mass index < 23, preoperative Braden score ≤ 14, anaemia, respiratory disease, and hypertension. The model had bootstrap-corrected c-statistic 0.78 indicating good discrimination. A cut-off score of ≥6 is strongly predictive, with a positive predictive value of 73.2% (confidence interval [CI]: 59.7%-84.2%) and a negative predictive value of 80.7% (CI: 74.3%-86.1%). SPURS contributes to the preoperative identification of pressure ulcer risk that could help nurses implement preventive measures earlier.

Abstract
PURPOSE The aim of this study is to describe clinical nurse specialists' characteristics, interest, confidence, motivators, and barriers in conducting research. DESIGN This study was a descriptive, multicohort design. METHODS Clinical nurse specialists were recruited electronically through national and local organizations to complete anonymous surveys 3 times, over 3 years. Comparative analyses included χ and Kruskal-Wallis tests. RESULTS Of 2052 responders (initial, n = 629; 18 months, n = 465; and 3 years, n = 958), mean (SD) participant age was 50.3 (9.3) years. Overall, 41.7% of participants were involved as principal or coinvestigators in research. Interest in conducting nursing research (on a 0-100 scale) was 61.1 (38.4) and was lowest among the 18-month time point participant group (score, 39.1 [32.2]) and highest at the 3-year time point (68.3, [30.7]; P < .001). Confidence in conducting research, discussion of statistics, and perceptions of motivators and barriers to conducting research did not differ across time period groups. Access to literature and mentors and research knowledge were the most prevalent barriers to conducting research. CONCLUSIONS Less than 42% of clinical nurse specialists conducted research and the rate did not change between different time groups. Access and knowledge barriers to conducting research were prominent. Workplace leaders need to consider resources and support of academic educational opportunities to increase research conduct by clinical nurse specialists.

Decubitus ulcers in patients undergoing vascular operations do not influence mortality but affect resource utilization. Surgery 2017; 161:1720-1727.

Abstract
BACKGROUND While it is anticipated that decubitus ulcers are detrimental to outcomes after vascular operations, the contemporary influence of perioperative decubitus ulcers in vascular surgery remains unknown. METHODS Using the National Impatient Survey, all adult patients who underwent vascular operation were selected. Patients were stratified by the presence or absence (non-decubitus ulcers) of decubitus ulcer. Case-mix adjusted hierarchical mixed-models examined in-hospital mortality, the occurrence of any complication, and discharge disposition. RESULTS A total of 538,808 cases were analyzed. Decubitus ulcers were most prevalent among Caucasian male Medicare beneficiaries (P < .001). Decubitus ulcer patients also underwent more nonelective vascular operations (P < .001). Wound, infectious, and procedural complications were more common in patients with decubitus ulcers (P < .001). Failure to rescue, defined as mortality after any complication, was more than doubled in decubitus ulcers (non-decubitus ulcers: 1.5%, decubitus ulcers: 3.2%, P < .001). Similarly, unadjusted mortality was also doubled in patients undergoing vascular operation with decubitus ulcers (non-decubitus ulcers: 3%, decubitus ulcers: 6%, P < .001). After risk adjustment among all patients, neither the presence of a decubitus ulcer nor specific ulcer staging increased the adjusted odds of death. Having a decubitus ulcer increased the adjusted odds of discharge to an intermediate care facility (odds ratio 2.9, P < .001). These patients also had 1.6 times the total charges compared to their non-decubitus ulcer cohort (non-decubitus ulcers: $49,460 ± $281 vs decubitus ulcers: $81,149 ± $5,855, P < .001). CONCLUSION Contrary to common perception, perioperative decubitus ulcer does not adversely affect mortality after vascular operation in patients proceeding to operative intervention. Patients with decubitus ulcers are, however, at higher risk for complications and incur sizeable additional charges.

Abstract
BACKGROUND Pressure ulcers (PUs) in the sacral region can be a complication of surgical procedures performed in the lithotomy position. Previous reports have noted a difference between men and women in PU development related to the supine position, and body weight and body mass index (BMI) have been also described as known risk factors in supine position-related PU development. The BIG-MAT® system is a noninvasive pressure distribution measurement device used to measure external pressure (EP). We used this system to investigate the relationship between EP to the sacral region in the lithotomy position and selected physical characteristics. METHODS We recruited 21 young, healthy volunteers (11 men and 10 women, aged 21.4±0.5 years). Using the BIG-MAT system, we measured four types of EP to the sacral region: box pressure, peak box pressure, contact pressure, and peak contact pressure. We analyzed the relationships between these dynamic parameters and physical characteristics of the participants. RESULTS There were no differences between men and women in the four types of EP, and no significant differences related to the participants' height, weight, or BMI. CONCLUSION An individual's height, weight, and BMI may not contribute to the risk of inducing lithotomy position-related PUs in the sacral region. The noninvasive pressure distribution measurement system BIG-MAT for patients in the lithotomy position during surgery could become a significant device when estimating EP at the sacral region.

Abstract
Objective Identify and analyze the incidence coefficients of pressure ulcers (PU) and the risk factors for PU development in critical patients with cardiopulmonary diseases. Method A prospective cohort study conducted in the cardiopulmonary intensive care unit (ICU) of a large hospital in the city of São Paulo, from November 2013 to February 2014. In total, 370 patients over 18 years old who did not present PU at admission and who had been in the ICU for less than 24 hours were studied. Data were analyzed by univariate and multivariate analyses (Classification And Regression Tree - CART). Results The incidence coefficients of PU were: 11.0% for total participants, 8.0% for male and 3.0% for female patients (p=0.018); 10.0% for white patients and 6.5% for patients 60 years or older. The main risk factors were length of stay in the ICU for 9.5 days or more, age 42.5 years or older, and being of the white race. Conclusion This study was related to the epidemiology of PU in critical patients with cardiopulmonary diseases, facilitating the planning of specific preventive care for these patients.
