Psychometric properties of the Braden scale to assess pressure injury risk in intensive care: A systematic review.

OBJECTIVE: To analyse the psychometric properties of the Braden scale to assess pressure injury risk in adults in intensive care. DESIGN: A systematic review was conducted, with literature searches undertaken in five electronic databases. No date limits were applied. Selection, data extraction and risk of bias assessment were completed by two reviewers independently. A customised data extraction template was used, with risk of bias conducted using the COSMIN Risk of Bias checklist. Data were analysed using narrative synthesis. RESULTS: Thirty-four studies met inclusion criteria. Two studies reported internal consistency with Cronbach's alpha ranging from poor (0.43) to good (0.85). For interrater reliability, only four studies reported intraclass correlation, ranging from 0.66 to 0.96 for Braden sum score. Three studies reported convergent validity, with strong associations found between the COMHON Index (r = 0.70), Cubbin-Jackson scale (r = 0.80), and Norton scale (r = 0.77), but contrasting associations with the Waterlow score (r = 0.22 to 0.72). A large majority of studies reported predictive validity (n = 29), with wide variability. Several studies investigated optimal cut-off scores, with the majority indicating this was in the range of 12-14. CONCLUSIONS: This review demonstrates inconsistency in the psychometric properties of the Braden scale in ICU settings. Further research is needed to determine suitability of the Braden scale for ICU before it can be recommended as standard for clinical practice, including comparison with other ICU-specific risk assessment tools. IMPLICATIONS FOR CLINICAL PRACTICE: When used in ICU, the reliability, validity and reported cut-off scores of the Braden scale are variable. As a predictive tool, the scale should be used cautiously. In ICU, the value of the Braden scale resides in its ability to identify patients that are most at risk of developing a pressure injury and to implement preventative measures to mitigate identified risk factors.

Complementing Braden scale for pressure ulcer risk with clinical and demographic-related factors in a large cohort of hospitalized Italian patients.

AIMS: To determine the prevalence, risk, and determinants of pressure ulcer risk in a large cohort of hospitalized patients. DESIGN: A prospective cross-sectional study with data collection in January 2023. METHODS: Registered nurses collected data from 798 patients admitted to 27 health care units of an Italian hospital. The pressure ulcer risk was assessed using the Braden scale. The presence of comorbidities was collected from clinical reports. Obesity was assessed according to international indicators (Body Mass Index). The receiver operating characteristic (ROC) curve was used to estimate the sensitivity and specificity of different Braden scores for identifying participants with pressure ulcers. RESULTS: The prevalence of pressure ulcers was 9.5%, and 57.4% of the sample were at risk of developing pressure ulcers. The area under the ROC curve was 0.88. The best sensitivity and specificity were found for a Braden cutoff score of 15.5 (sensibility = 0.76; specificity = 0.85). The determinants of lower Braden scores were older age (p < 0.001), comorbidities (p < 0.001), wounds of other nature (p = 0.001), urinary incontinence (p < 0.001), fecal incontinence (p < 0.001), and urinary catheterization (p < 0.001). CONCLUSION: Several demographic factors and specific clinical indicators have been identified as determinants of the risk of developing pressure ulcers, which are easily ascertainable by healthcare providers; thus, they may routinely complement the Braden Scale in the assessment of pressure ulcer risk in order to reinforce and accelerate clinical judgment.

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.

A simplified BRADEN scale for the risk of developing pressure injuries.

BACKGROUND: Pressure injuries (PIs) are a major problem for healthcare providers, impacting both care costs and patients' quality of life, although they are predominately preventable. These injuries are especially present in Intensive Care Units (ICUs) as a result of the severity of the clinical conditions of patients in this unit. AIM: To develop a simplified version of the Braden scale by removing two of the most subjective subscores-Nutrition and Sensory Perception-in an attempt to reduce the chance of errors by the nursing team during the application of the scale. STUDY DESIGN: A cross-sectional study was conducted on data collected from patients admitted to the ICU of a private Brazilian tertiary hospital. The resulting data consisted of 5194 patients, 6353 hospital admissions, and 6974 ICU stays. The overall prevalence of PI was 1.09%. RESULTS: The T-test showed that both the Braden and the simplified Braden scores were significantly different between patients with and without PI (p < .001). Patients who developed PIs scored lower than those who did not. The area under the Receiver Operating Characteristic curve of the Braden Scale was 74.21% (95% CI: 68.61%-79.8%) and of the simplified scale was 72.54% (95% CI: 66.87%-78.22%). The Positive Predictive Value of the Braden Scale was 3.17% when interpolated at the same sensitivity as the simplified scale (47.37%), which achieved 3.26%. CONCLUSIONS: By removing two of the six subscores of the Braden scale we propose a new tool for identifying patients at risk of developing PI in a more objective and fast way. Our results show that classification performance had little negative impact. RELEVANCE TO CLINICAL PRACTICE: A simplified, less subjective scale allows for more precise and less time-consuming risk classification.

Comparison of the predictive validity of the Braden and Waterlow scales in intensive care unit patients: A multicentre study.

BACKGROUND: The first step in preventing pressure injuries (PIs), which represent a significant burden on intensive care unit (ICU) patients and the health care system, is to assess the risk for developing PIs. A valid risk assessment scale is essential to evaluate the risk and avoid PIs. OBJECTIVES: To compare the predictive validity of the Braden scale and Waterlow scale in ICUs. DESIGN: A multicentre, prospective and cross-sectional study. METHODS: We conducted this study among 6416 patients admitted to ICUs in Gansu province of China from April 2021 to October 2022. The incidence and characteristics of PIs were collected. The risk assessment of PIs was determined using the Braden and Waterlow scale. The sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve of the two scales were compared. RESULTS: Out of 5903 patients, 72 (1.2%) developed PIs. The sensitivity, specificity, positive and negative predictive, and the area under the curve of the Braden scale were 77.8%, 50.9%, 0.014 and 0.996, and 0.689, respectively. These values for the Waterlow scale were 54.2%, 71.1%, 0.017, 0.994 and 0.651. CONCLUSIONS: Both scales could be used for risk assessment of PIs in ICU patients. However, the accuracy of visual inspection for assessment of skin colour, nursing preventive measures for patients and scales inter-rater inconsistency may limited the predictive validity statistics. RELEVANCE TO CLINICAL PRACTICE: Both scales could be used for PIs risk assessment. The low specificity of the Braden scale and low sensitivity of the Waterlow scale remind medical staff to use them in combination with clinical judgement and other objective indicators. PATIENT OR PUBLIC CONTRIBUTION: This study was designed to enhance the management of PIs. Patients and the general public were not involved in the study design, analysis, and interpretation of the data or manuscript preparation.

Epidemiological characteristics of pressure injury and the predictive validity of Braden scale among the older hospitalized patients: A cross-sectional study.

AIMS AND OBJECTIVES: To investigate the epidemiological characteristics of pressure injury (PI) in older inpatients and predictive validity of the Braden scale. DESIGN: Cross-sectional study. METHODS: Conducted in a 2600-bed tertiary hospital in Northwestern China from January to June 2022, the study included older patients (≥60 years). The Braden scale was used for the risk assessment of PI, and the epidemiological characteristics of PI were observed. The contributing factors of PI in older inpatients were examined using univariate and multiple or multivariable logistic regression analysis. The predictive validity and optimal cut-off value were assessed using receiver operating curve (ROC). RESULTS: The study included 13,064 older patients, with a PI incidence of 0.20%, with the highest incidence (0.95%) in those aged ≥80. Age, BMI, Braden score and length of hospital stay were related to PI occurrence. The Braden scale showed an AUC of 0.905 for predicting PI in older inpatients, with a sensitivity of 84.6% and specificity of 86.4%. The optimal cut-off value of 19 yielded the best predictive performance with a Yoden index of 0.710. CONCLUSION: PI is most likely to occur in older inpatients with older age, longer hospital stay, lower BMI and Braden score. The Braden scale demonstrated good suitability for predicting PI risk in this population, with an optimal cut-off value of 19 showing improved predictive accuracy. PATIENT OR PUBLIC CONTRIBUTION: Throughout the investigation, patients or family members cooperated to complete all data investigation and evaluation, and nurses assisted in PI risk assessment, skin evaluation and other work.

Introduction: The Braden scale is recommended and widely used in evaluating the prediction of pressure injuries. Critical patients admitted to intensive care when correlated with biochemical markers can reveal a high risk for the development of this type of injury. Objectives: Correlate the Braden scale with biochemical markers of patients admitted to an intensive care unit and identify, through the clinical laboratory profile, the risk for developing pressure injuries. Methods: This is a descriptive, quantitative and prospective study, in search of correlation between the subjects. Data collection was carried out over a month, with analysis of medical records of patients admitted to the Intensive Care Unit, by the researcher himself, on alternate days of the week. Hospitalized patients were included, with a Braden score and relevance for risk of pressure injuries, minimal, medium and high, and the latest laboratory test results were used. Exclusion criteria were incomplete data in the medical record. The data collection instrument, constructed by the researcher himself, included demographic data, Braden score, comorbidities, Glasgow scale, devices used, levels of C-Reactive protein, hematocrit, hemoglobin, albumin, leukocytes, creatine and blood glucose. Results: The study sample consisted of 54 patients, 29 (53.71%) were female and 25 (46.29%) were male. Among the comorbidities, 35.18% were hypertensive, 18.51% were hypertensive and diabetic, 1.85% had diabetes and 37.03% had no comorbidities. The majority were not smokers or alcoholics, 59.25% were using mechanical ventilation, 55.66% used a nasogastric/nasoenteric tube and 79.6% had an indwelling bladder catheter. The Glasgow scale mean was 7.98 and the Braden scale was 13.65. According to the Braden scale score associated with biochemical markers, it was observed that patients at low risk showed no correlation, while patients classified in the medium and high risk group showed a correlation between the Braden score and C-reactive protein, an important predictor of inflammation. Conclusion: Assessing the risk of pressure injuries is essential, especially for critically ill patients and the biochemical marker that stood out the most was PCR, proving the patient's severity. The nursing team must be capable and use the resources available in the unit, pertinently and effectively assisting patients with serious clinical conditions.

Improving Pressure Ulcers Prediction in Nursing Homes with ML Algorithm.

An automated ML classifier predicting pressure ulcers one-month before performs better than the reference methods currently used in nursing homes.

An Integrated System of Braden Scale and Random Forest Using Real-Time Diagnoses to Predict When Hospital-Acquired Pressure Injuries (Bedsores) Occur.

BACKGROUND AND OBJECTIVES: Bedsores/Pressure Injuries (PIs) are the second most common diagnosis in healthcare system billing records in the United States and account for 60,000 deaths annually. Hospital-Acquired Pressure Injuries (HAPIs) are one classification of PIs and indicate injuries that occurred while the patient was cared for within the hospital. Until now, all studies have predicted who will develop HAPI using classic machine algorithms, which provides incomplete information for the clinical team. Knowing who will develop HAPI does not help differentiate at which point those predicted patients will develop HAPIs; no studies have investigated when HAPI develops for predicted at-risk patients. This research aims to develop a hybrid system of Random Forest (RF) and Braden Scale to predict HAPI time by considering the changes in patients' diagnoses from admission until HAPI occurrence. METHODS: Real-time diagnoses and risk factors were collected daily for 485 patients from admission until HAPI occurrence, which resulted in 4619 records. Then for each record, HAPI time was calculated from the day of diagnosis until HAPI occurrence. Recursive Feature Elimination (RFE) selected the best factors among the 60 factors. The dataset was separated into 80% training (10-fold cross-validation) and 20% testing. Grid Search (GS) with RF (GS-RF) was adopted to predict HAPI time using collected risk factors, including Braden Scale. Then, the proposed model was compared with the seven most common algorithms used to predict HAPI; each was replicated for 50 different experiments. RESULTS: GS-RF achieved the best Area Under the Curve (AUC) (91.20 ± 0.26) and Geometric Mean (G-mean) (91.17 ± 0.26) compared to the seven algorithms. RFE selected 43 factors. The most dominant interactable risk factors in predicting HAPI time were visiting ICU during hospitalization, Braden subscales, BMI, Stimuli Anesthesia, patient refusal to change position, and another lab diagnosis. CONCLUSION: Identifying when the patient is likely to develop HAPI can target early intervention when it is needed most and reduces unnecessary burden on patients and care teams when patients are at lower risk, which further individualizes the plan of care.

Risk factors for pressure ulcers in adult patients: A meta-analysis on sociodemographic factors and the Braden scale.

AIMS AND OBJECTIVES: Providing the first meta-analysis of risk factors for pressure ulcer development in adult patients. BACKGROUND: Pressure ulcers remain a serious health complication for patients and nursing staff. However, there is a lack of statistical evidence for risk factors as previous research did not include any quantitative synthesis. DESIGN: Meta-analysis, using PRISMA guidelines. METHODS: Studies from PubMed, Embase, CINAHL Complete, Web of Science, Cochrane Library, and other reviews and sources were screened and checked against the inclusion criteria. The risk of bias was evaluated using a slightly modified QUIPS tool. Data regarding population, design, statistical analysis and risk factors were extracted. Meta-analysis with comparable studies was conducted for age, sex, and Braden scale. The sub-group analysis was used to account for heterogeneity. RESULTS: 28 studies with 570,162 patients were entered in meta-analysis. Older age and a low total Braden scale score increased the risk for pressure ulcers. All subscales excluding 'moisture' reached significance in meta-analysis based only on few studies, however, limiting overall evidence. Male sex achieved mixed results, too. CONCLUSION: The first meta-analytic analysis shows evidence for age and Braden scale as risk factors for pressure ulcer development. Limitations regarding study quality and heterogeneity must be considered, highlighting the need for unifying certain conditions in risk factor research. RELEVANCE TO CLINICAL PRACTICE: Patients at risk for new pressure ulcers can be identified by their total Braden score and age, whereas the latter is also connected to deeper pressure ulcers. Nurses and health personnel should pay great attention to patients in older age and undergo specific training to utilise and evaluate the Braden scale effectively, if necessary.

Nursing Assessment of Pressure Injury Risk with the Braden Scale Validated against Sensor-Based Measurement of Movement.

Nursing staff assessment to accurately identify pressure injury (PrI) risk is a hallmark in PrI prevention care. Risk scores from the Braden Scale for Predicting Pressure Sore Risk© (hereafter Braden), a commonly used tool for assessing PrI risk, signal the need for preventative care. Braden Mobility, Activity, and Sensory Perception subscale subgroups associated with repositioning movement features help identify preventative strategies that minimize pressure intensity and duration. Evidence confirming subscale rating accuracy is needed. This study compared assessment score accuracy with movement data collected via accelerometer sensor. Sample included 913 nursing home residents from the Turn Everyone and Move for Pressure Ulcer Prevention (TEAM-UP) cluster randomized trial. Movements and Braden Mobility and Activity subscale scores were evaluated for significant differences and associations. Mobility subgroups explained a small-medium amount of variance in mean lying and upright movement features (0.002 ≤ R2 ≤ 0.195). Activity subgroups explained a small-medium amount of variance in mean lying, upright, and ambulating movements (0.016 ≤ R2 ≤ 0.248). Significant associations occurred among subscale subgroups and most movements. Nursing assessment ratings using Braden scale's Mobility and Activity subscale scores are accurate indicators of actual repositioning movements and can be relied upon for PrI prevention care planning for older adults.

Decision-Tree-Based Approach for Pressure Ulcer Risk Assessment in Immobilized Patients.

Applications where data mining tools are used in the fields of medicine and nursing are becoming more and more frequent. Among them, decision trees have been applied to different health data, such as those associated with pressure ulcers. Pressure ulcers represent a health problem with a significant impact on the morbidity and mortality of immobilized patients and on the quality of life of affected people and their families. Nurses provide comprehensive care to immobilized patients. This fact results in an increased workload that can be a risk factor for the development of serious health problems. Healthcare work with evidence-based practice with an objective criterion for a nursing professional is an essential addition for the application of preventive measures. In this work, two ways for conducting a pressure ulcer risk assessment based on a decision tree approach are provided. The first way is based on the activity and mobility characteristics of the Braden scale, whilst the second way is based on the activity, mobility and skin moisture characteristics. The results provided in this study endow nursing professionals with a foundation in relation to the use of their experience and objective criteria for quick decision making regarding the risk of a patient to develop a pressure ulcer.

Pressure Ulcers Risk Assessment According to Nursing Criteria.

Pressure ulcers (PU) represent a health problem with a significant impact on the morbidity and mortality of immobilized patients, and on the quality of life of affected people and their families. Risk assessment of pressure ulcers incidence must be carried out in a structured and comprehensive manner. The Braden Scale is the result of an analysis of risk factors that includes subscales that define exactly what should be interpreted in each one. The healthcare work with evidence-based practice with an objective criterion by the nursing professional is an essential addition for the application of preventive measures. Explanatory models based on the different subscales of Braden Scale purvey an estimation to level changes in the risk of suffering PU. A binary-response logistic regression model, supported by a study with an analytical, observational, longitudinal, and prospective design in the Granada-Metropolitan Primary Healthcare District (DSGM) in Andalusia (Southern Spain), with a sample of 16,215 immobilized status patients, using a Braden Scale log, is performed. A model that includes the mobility and activity scales achieves a correct classification rate of 86% (sensitivity (S) = 87.57%, specificity (SP) = 81.69%, positive predictive value (PPV) = 91.78%, and negative preventive value (NPV) = 73.78%), while if we add the skin moisture subscale to this model, the correct classification rate is 96% (S = 90.74%, SP = 88.83%, PPV = 95.00%, and NPV = 80.42%). The six subscales provide a model with a 99.5% correct classification rate (S = 99.93%, SP = 98.50%, PPV = 99.36%, and NPV = 99.83%). This analysis provides useful information to help predict this risk in this group of patients through objective nursing criteria.

Relationship between pressure ulcer risk and sarcopenia in patients with hip fractures.

OBJECTIVE: Pressure ulcer (PU) is a frequent complication of hip fractures. PUs can develop at any time after a hip fracture but most appear within 2-4 days after surgery. The purpose of this study was to investigate the association between hip fractures due to sarcopenia and the risk of PUs in patients with hip fracture. METHOD: Between March 2017 and March 2019, patients aged ≥65 years of age with hip fractures were included in this retrospective cohort study. PU risk assessment according to the Braden Scale was performed within the first few hours after arrival at hospital. Skeletal muscle mass index (SMI) and hand grip strength were evaluated for a diagnosis of sarcopenia. RESULTS: Of the 289 patients admitted to the study institution, 180 patients were finally enrolled in the study (129 females; 51 males). In male patients, as SMI increased, so too did the Braden Scale score, which was statistically significant (p=0.02). However, there was no statistically significant difference between SMIs and Braden Scale scores in female patients (p=0.304). In male patients, there was no statistically significant difference between hand grip strength and Braden Scale score (p=0.251). However, in female patients, as hand grip strength increased, so too did the Braden Scale score; this was also statistically significant (p=0.041). CONCLUSION: In this study, decreased muscle mass and muscle weakness in patients with hip fractures were associated with increased PU risk as measured by Braden Scale scores in both males and females.

A Cartoon Version of Braden Scale to Assess the Risk of Pressure Injury: Content Validity and Interrater Reliability Study.

INTRODUCTION: The Braden Scale is widely used to assess the risk of pressure injury. However, the vague literal description of the items creates difficulties for bedside nurses and limits its sensitivity. To solve this problem, we developed a cartoon version of the Braden scale (CVBS) to improve the pressure injury risk assessment ability of bedside nurses. METHODS: The CVBS was constructed by two nurses, and the final version was determined through a two-round Delphi consultation. The scale's content validity was calculated based on expert ratings. A total of 265 patients were evaluated simultaneously with the CVBS by 119 bedside nurses and 46 wound care specialists; and 114 bedside nurses and the same 46 wound care specialists evaluated 239 patients with the original Braden scale (OBS). The interrater reliability between the two groups was calculated as Kappa value, and then the Kappa values of the two versions were compared. RESULTS: The content validity for the draft scale was not good enough. After modification, the indices of all the items in the final CVBS reached 1.00. The Kappa value of the OBS was 0.69 (95% CI 0.61-0.76); for each item, it ranged from 0.60 to 0.80. The interrater reliabilities of the CVBS were higher than those of the OBS, with an overall kappa value of 0.87 (95% CI 0.81-0.92) and a range of 0.77 to 0.93 for each item. The differences between the Kappa values of the CVBS and those of the OBS were all statistically significant. CONCLUSIONS: The CVBS had good validity and showed higher interrater reliability than the OBS, indicating that it may improve bedside nurses' ability to assess pressure injury risk.

Factors affecting the incidence and prevalence of pressure ulcers in COVID-19 patients admitted with a Braden scale below 14 in the intensive care unit: Retrospective cohort study.

The pandemic of coronavirus (COVID-19) has significantly increased the admission of patients with extensive complications, especially for respiratory support, to intensive care units (ICUs) worldwide. These patients also suffer from pressure ulcers (PUs) as another complication that occurs due to increased length of hospitalisation and acute conditions of patients. Therefore, this study aimed to evaluate the incidence and prevalence of PU and the factors affecting it in COVID-19 patients admitted to ICUs. This cohort retrospective study used registry data in Imam Reza Hospital located in west of Iran. Four hundred and forty-five COVID-19 patients older than 20 years hospitalised in corona ICUs from 20 March 2020 to 30 December 2020, with a Braden score of less than 14 were included in the study. To investigate the relationship between variables in rate prevalence, univariate logistic regression analysis was used to calculate odds ratio, and for incidence rate in estimating PU risk generated in ICUs, hazard ratio was calculated using cox regression. One hundred and eighty-three (41.12%) patients were male. The mean age of patients was 63 (SD = ±9.78) years. A total of 1152 cases of PU were generated, with the highest prevalence of PU with 234 cases in the sacrum. One hundred and seventy-six (55.87%) patients underwent non-invasive ventilation ulcers. The prevalence of PU was 79.7%. The highest prevalence was found in people over 80 years with 90.67%. The incidence ratio was 46.74%. The highest number of new cases was seen in diabetic patients with 60.96%. First-degree ulcers were the most common degree of ulceration in 252 (55.38%) patients. Incidence and prevalence excluding first-degree wounds were 24.04% and 49.66%, respectively. Age, Braden score, BMI, comorbidity, diabetes mellitus, stool incontinence, Glasgow coma scale, vasopressor, and length of hospital stay were significantly associated with PU (P < .05). The incidence and prevalence of PU in patients were high in this study. The length of hospitalisation and Braden score were the most important factors in the development of PU. The widespread prevalence of COVID-19 and the relatively long stay of patients in the ICU created unfavourable conditions for patients and the treatment system, therefore, it emphasised the use of appropriate measures to prevent PU to avoid double costs and longer stays.

A Hybrid System of Braden Scale and Machine Learning to Predict Hospital-Acquired Pressure Injuries (Bedsores): A Retrospective Observational Cohort Study.

Background: The Braden Scale is commonly used to determine Hospital-Acquired Pressure Injuries (HAPI). However, the volume of patients who are identified as being at risk stretches already limited resources, and caregivers are limited by the number of factors that can reasonably assess during patient care. In the last decade, machine learning techniques have been used to predict HAPI by utilizing related risk factors. Nevertheless, none of these studies consider the change in patient status from admission until discharge. Objectives: To develop an integrated system of Braden and machine learning to predict HAPI and assist with resource allocation for early interventions. The proposed approach captures the change in patients' risk by assessing factors three times across hospitalization. Design: Retrospective observational cohort study. Setting(s): This research was conducted at ChristianaCare hospital in Delaware, United States. Participants: Patients discharged between May 2020 and February 2022. Patients with HAPI were identified from Nursing documents (N = 15,889). Methods: Support Vector Machine (SVM) was adopted to predict patients' risk for developing HAPI using multiple risk factors in addition to Braden. Multiple performance metrics were used to compare the results of the integrated system versus Braden alone. Results: The HAPI rate is 3%. The integrated system achieved better sensitivity (74.29 ± 1.23) and detection prevalence (24.27 ± 0.16) than the Braden scale alone (sensitivity (66.90 ± 4.66) and detection prevalence (41.96 ± 1.35)). The most important risk factors to predict HAPI were Braden sub-factors, overall Braden, visiting ICU during hospitalization, and Glasgow coma score. Conclusions: The integrated system which combines SVM with Braden offers better performance than Braden and reduces the number of patients identified as at-risk. Furthermore, it allows for better allocation of resources to high-risk patients. It will result in cost savings and better utilization of resources. Relevance to clinical practice: The developed model provides an automated system to predict HAPI patients in real time and allows for ongoing intervention for patients identified as at-risk. Moreover, the integrated system is used to determine the number of nurses needed for early interventions. Reporting Method: EQUATOR guidelines (TRIPOD) were adopted in this research to develop the prediction model. Patient or Public Contribution: This research was based on a secondary analysis of patients' Electronic Health Records. The dataset was de-identified and patient identifiers were removed before processing and modeling.

Factors associated with pressure ulcer onset after knee replacement.

OBJECTIVE: The aim of this study was to find the rate of pressure ulcers (PUs) in patients with knee replacements and identify predictive factors. The ability of the Braden scale to predict the onset of PUs was also investigated. METHOD: A retrospective prognostic cohort study was carried out involving all consecutive patients undergoing knee replacement surgery. The data were collected from patient records. The variables collected were grouped into two categories: those connected to the patient's own characteristics; and those linked to the care methods used. RESULTS: The total number of patients included in the study was 565. Of these, 2.3% had developed a PU: 0.5% at the heel and 1.8% at the sacrum. Multivariate analysis showed that the variables actually correlated to the outcome were age (p=0.074; odds ratio (OR)=1.08), body mass index (BMI, p=0.037; OR=1.13) and Braden scale (p=0.029; OR=0.72). A combination of these three parameters showed better predictivity of PUs (area under the curve (AUC) 84%). CONCLUSION: Age, BMI and preoperative Braden score were shown to be independent predictive factors of the onset of PUs in patients with knee replacements. The combined use of all three variables increased the ability to identify the patients at most risk of developing a PU. DECLARATION OF INTEREST: The study was financed by the Professional Nurse Register of Bologna as winner of a competition for research projects in the province of Bologna.

Admission Braden Scale Score as an Early Independent Predictor of In-Hospital Mortality Among Inpatients With COVID-19: A Retrospective Cohort Study.

BACKGROUND: The COVID-19 pandemic has put a strain on health systems. Predictors of adverse outcomes need to be investigated to properly manage COVID-19 patients. The Braden Scale (BS), commonly used for the assessment of pressure ulcer risk, has recently been proposed to identify frailty. OBJECTIVE: To investigate the predictive utility of the BS for prediction of in-hospital mortality in a cohort of COVID-19 patients admitted to non-ICU wards. METHODS: We conducted a retrospective single-center cohort study evaluating all patients with SARS-CoV-2 infection consecutively admitted over a 2-month period (from March 6 to May 7, 2020) to the COVID-19 general wards of our institution. Demographic, clinical, and nursing assessment data, including admission BS, were extracted from electronic medical records. Univariable and multivariable logistic regression models were used to explore the association between the BS score and in-hospital death. RESULTS: Braden Scale was assessed in 146 patients (mean age 74.7 years; 52% males). On admission, 46 had a BS ≤ 15, and 100 patients had a BS > 15. Mortality among patients with BS ≤ 15 was significantly higher than in patients with BS > 15 (45.7% vs. 16%; p < .001). On multivariable regression analysis, adjusting for potentials confounders (age, Barthel scale, chronic kidney disease, atrial fibrillation, and hypertension), the admission BS remained inversely associated with the risk of in-hospital mortality (OR = 0.76; 95% CI [0.60, 0.96]; p = .020). LINKING EVIDENCE TO ACTION: Admission BS could be used as a simple bedside predictive tool able to early identify non-ICU COVID-19 patients with poor prognosis who might benefit from specific and timely interventions.
