Self-inflicted burns in Brazil: systematic review and meta-analysis.

INTRODUCTION: burns represent a pivotal component of trauma in Brazil, accounting for 2 million incidents and 2,500 deaths annually. Self-intentional burns are associated with a worse prognosis, larger burned surface area, higher infection rates, and death. The lack of studies on the issue of self-immolation raises epidemiological questions regarding Brazilian victims. This study aimed to investigate the profile of burn events associated with self-injurious behavior among Brazilian victims. METHODS: this systematic review was performed according to PRISMA 2020 guidelines and evaluated the correlation between self-injurious behavior as a cause of burns in Brazilian victims and its epidemiological implications in the last 20 years (2003-2023). The MeSH terms "Burns", "Self-Injurious Behavior", "Epidemiology" and "Brazil" were queried in the PubMed/MEDLINE, SciELO, and Cochrane Library databases, and, after selection by inclusion/exclusion criteria, the most relevant studies were critically analyzed. RESULTS: From 1,077 pre-selected studies, 92 were potentially eligible, resulting in 7 manuscripts incorporated in this review. From 3,510 burned victims assembled in the pool of selected studies, 311 cases displayed self-injurious behavior. Burned patients who attempted to burn their lives have a higher risk of death (p<0.05; RR=5.1 [3.2-8.1]) and larger burned surface area (p<0.05; MD=19.2 [10-28.2]), compared to accidental cases. Moreover, the female gender was at a higher risk of attempting self-immolation (p<0.05; RR=4.01 [2.9-5.5]). CONCLUSION: our results show that self-inflicted burn cases were associated with a larger burned surface area and a higher risk of death, and the female gender was identified as a relevant risk factor in Brazil.

Epidemiological Predictors of Financial Toxicity in Surgical Burn Injuries: A Multicenter, Longitudinal, Cohort Study.

BACKGROUND: Burns constitute a major global health challenge, causing over 11 million injuries and 300,000 deaths annually and surpassing the economic burden of cervical cancer and HIV combined. Despite this, patient-level financial consequences of burn injuries remain poorly quantified, with a significant gap in data from low- and middle-income countries. In this study, we evaluate financial toxicity in burn patients. METHODS: A prospective, multicenter cohort study was conducted across two tertiary care hospitals in India, assessing 123 adult surgical in-patients undergoing operative interventions for burn injuries. Patient sociodemographic, clinical, and financial data were collected through surveys and electronic records during hospitalization and at 1, 3, and 6 months postoperatively. Out-of-pocket costs (OOPCs) for surgical burn treatment were evaluated during hospitalization. Longitudinal changes in income, employment status, and affordability of basic subsistence needs were assessed at the 1-, 3-, and 6-month postoperative time point. Degree of financial toxicity was calculated using a combination of the metrics catastrophic health expenditure and financial hardship. Development of financial toxicity was compared by sociodemographic and clinical characteristics using logistic regression models. RESULTS: Of the cohort, 60% experienced financial toxicity. Median OOPCs was US$555.32 with the majority of OOPCs stemming from direct nonmedical costs (US$318.45). Cost of initial hospitalization exceeded monthly annual income by 80%. Following surgical burn care, income decreased by US$318.18 within 6 months, accompanied by a 53% increase in unemployment rates. At least 40% of the cohort consistently reported inability to afford basic subsistence needs within the 6-month perioperative period. Significant predictors of developing financial toxicity included male gender (odds ratio, 4.17; 95% confidence interval, 1.25-14.29; P = 0.02) and hospital stays exceeding 20 days (odds ratio, 11.17; 95% confidence interval, 2.11-59.22; P ≤ 0.01). CONCLUSIONS: Surgical treatment for burn injuries is associated with substantial financial toxicity. National and local policies must expand their scope beyond direct medical costs to address direct nonmedical and indirect costs. These include burn care insurance, teleconsultation follow-ups, hospital-affiliated subsidized lodging, and resources for occupational support and rehabilitation. These measures are crucial to alleviate the financial burden of burn care, particularly during the perioperative period.

[A cross-sectional survey and analysis of influencing factors on the occurrence of post-burn psychological stress disorder in preschool children].

Objective: To explore the occurrence and influencing factors of post-burn psychological stress disorder in preschool children. Methods: This study was a multi-center cross-sectional survey. From January 2022 to February 2023, 85 preschool children (aged 1 to 6 years) with burns admitted to the Affiliated Hospital of North Sichuan Medical College, Nanchong Central Hospital, Suining Central Hospital, Guang'an People's Hospital, and Guangyuan Central Hospital who met the inclusion criteria were selected as respondents. A self-made general information questionnaire was used to investigate the children's general data including gender, age group, residential area, main caregiver and their education level, and family type, as well as the injury condition including cause of injury and burn severity. The Child Stress Disorders Checklist was used to investigate the occurrence of psychological stress disorder in children at 3 days to 1 month after injury, and the incidence rate was calculated. The children were classified according to their general data and injury condition, and the occurrence of psychological stress disorder in children at 3 days to 1 month after injury was recorded, and the influencing factors for post-burn psychological stress disorder in preschool children were screened. Results: A total of 85 questionnaires were distributed and 85 valid questionnaires were recovered, with an effective recovery rate of 100%. Among the children, there were 45 boys and 40 girls, with most children aged 1 to 3 years. There were slightly more children in rural areas than in cities. About half of the children were mainly cared for by their parents and grandparents, respectively, and the education level of the main caregivers was mainly high school/technical secondary school. The family type was mainly core family and extended family. The main cause of injury was hydrothermal scald, and the severity of burns was mainly moderate. The incidence rate of psychological stress disorder in this group of children at 3 days to 1 month after injury was 34.12% (29/85). There were statistically significant differences in the occurrence of psychological stress disorder in children with different age groups, causes of injuries, and burn severity at 3 days to 1 month after injury (with χ2 values​​of 9.18, 7.80, and 25.47, respectively, P<0.05); there were no statistically significant differences in the occurrence of psychological stress disorder in children with different genders, residential area, main caregivers, main caregivers' education levels, or family types at 3 days to 1 month after injury (P>0.05). Multivariate logistic regression analysis showed that age group and burn severity were independent influencing factors for the occurrence of psychological stress disorder in preschool children after burns (with odds ratios of 8.21 and 33.99, respectively, and 95% confidence intervals of 1.57-43.04 and 5.55-207.93, respectively, P<0.05), the older the child and the more severe the burn, the higher the possibility of the occurrence of psychological stress disorder. Conclusions: The incidence rate of psychological stress disorder is high in preschool children after burns. Age group and burn severity are independent influencing factors for the occurrence of post-burn psychological stress disorder in this type of children.

Incidence and predictors of thermal oesophageal and vagus nerve injuries in Ablation Index-guided high-power-short-duration ablation of atrial fibrillation: a prospective study.

AIMS: High-power-short-duration (HPSD) ablation is an effective treatment for atrial fibrillation but poses risks of thermal injuries to the oesophagus and vagus nerve. This study aims to investigate incidence and predictors of thermal injuries, employing machine learning. METHODS AND RESULTS: A prospective observational study was conducted at Leipzig Heart Centre, Germany, excluding patients with multiple prior ablations. All patients received Ablation Index-guided HPSD ablation and subsequent oesophagogastroduodenoscopy. A machine learning algorithm categorized ablation points by atrial location and analysed ablation data, including Ablation Index, focusing on the posterior wall. The study is registered in clinicaltrials.gov (NCT05709756). Between February 2021 and August 2023, 238 patients were enrolled, of whom 18 (7.6%; nine oesophagus, eight vagus nerve, one both) developed thermal injuries, including eight oesophageal erythemata, two ulcers, and no fistula. Higher mean force (15.8 ± 3.9 g vs. 13.6 ± 3.9 g, P = 0.022), ablation point quantity (61.50 ± 20.45 vs. 48.16 ± 19.60, P = 0.007), and total and maximum Ablation Index (24 114 ± 8765 vs. 18 894 ± 7863, P = 0.008; 499 ± 95 vs. 473 ± 44, P = 0.04, respectively) at the posterior wall, but not oesophagus location, correlated significantly with thermal injury occurrence. Patients with thermal injuries had significantly lower distances between left atrium and oesophagus (3.0 ± 1.5 mm vs. 4.4 ± 2.1 mm, P = 0.012) and smaller atrial surface areas (24.9 ± 6.5 cm2 vs. 29.5 ± 7.5 cm2, P = 0.032). CONCLUSION: The low thermal lesion's rate (7.6%) during Ablation Index-guided HPSD ablation for atrial fibrillation is noteworthy. Machine learning based ablation data analysis identified several potential predictors of thermal injuries. The correlation between machine learning output and injury development suggests the potential for a clinical tool to enhance procedural safety.

Do they stay, or do they go? Children presenting to five emergency departments across New South Wales, Australia with acute burn injuries: a retrospective review.

OBJECTIVE: The overall objective of the study was to describe the disposition status of children presenting with a burn injury to five emergency departments (ED) across New South Wales (NSW), Australia. DESIGN: A retrospective study design was used to review routinely collected ED data. SETTING: Study sites included five acute hospitals across NSW, Australia. PARTICIPANTS: During the 5-year study period between 1 January 2015 to 31 December 2020, there were 5213 paediatric burn injury presentations. RESULTS: The mean age of burn injury presentations was 24 months (Inter-Quartile-Range (IQR) 12-84), of which 57% (2951/5213) were males. The most common presentation time was between 16:00 and 23:59 hours (63%, 3297/5213), and the median time spent in the ED was 3 hours (IQR 1-4). The majority (80%, 4196/5213) of the burn injuries presentations did not require hospital admission. The most common principal diagnoses were 'Burn body region unspecified' (n=1916) and 'Burn of wrist and hand' (n=1060). CONCLUSION: Most children who presented to the hospital with a burn injury were not admitted. Often the details of these burns were poorly recorded and a complete picture of the true burden of burn injury in children, especially the ongoing care given outside the acute hospital setting, is missing. This information is crucial, as it would inform future models of care as the paradigm shifts rapidly towards primary, ambulatory and outpatient models of care.

The impact of different co-morbidities on clinical outcomes and resource utilization in critically ill burn and surgical patients: A population-based analysis of social determinants of health.

BACKGROUND: This study aims to establish the significance of social determinants of health and prevalent co-morbidities on multiple indicators for quality of care in patients admitted to the Burn and Surgical Intensive Care Unit (ICU). METHODS: We performed a retrospective analysis of population group data for patients admitted at the Burn and Surgical ICU from January 1, 2016, to November 18, 2019. The primary outcomes were length of hospital stay (LOS), mortality, 30-day readmission, and hospital charges. Pearson's chi-square test for categorical variables and t-test for continuous variables were used to compare population health groups. RESULTS: We analyzed a total of 487 burn and 510 surgical patients. When comparing ICU patients, we observed significantly higher mean hospital charges and length of stay (LOS) in BICU v. SICU patients with a history of mental health ($93,259.40 v. $50,503.36, p = 0.013 and 16.28 v. 9.16 days, p = 0.0085), end-stage-renal-disease (ESRD) ($653,871.05 v. $75,746.35, p = 0.0047 and 96.15 v. 17.53 days, p = 0.0104), sepsis ($267,979.60 v. $99,154.41, p = <0.001 and 39.1 v. 18.42 days, p = 0.0043), and venous thromboembolism (VTE) ($757,740.50 v. $117,816.40, p = <0.001 and 93.11 v. 20.21 days, p = 0.002). Also, higher mortality was observed in burn patients with ESRD, ST-Elevation Myocardial Infarction (STEMI), sepsis, VTE, and diabetes mellitus. 30-day-readmissions were greater among burn patients with a history of mental health, drug dependence, heart failure, and diabetes mellitus. CONCLUSIONS: Our study provides new insights into the variability of outcomes between burn patients treated in different critical care settings, underlining the influence of comorbidities on these outcomes. By comparing burn patients in the BICU with those in the SICU, we aim to highlight how differences in patient backgrounds, including the quality of care received, contribute to these outcomes. This comparison underscores the need for tailored healthcare strategies that consider the unique challenges faced by each patient group, aiming to mitigate disparities in health outcomes and healthcare spending. Further research to develop relevant and timely interventions that can improve these outcomes.

The incidence of cancer following hospitalisation for a burn injury in Scotland 2009-2019: A retrospective cohort study.

BACKGROUND: Studies suggest increased occurrence of cancer in persons who have experienced a burn injury with hospital admission. OBJECTIVE: To determine the incidence of cancer among those hospitalised for burn injuries in Scotland compared with a similar group without a history of burn injury hospitalisation. METHOD: A retrospective cohort design was used to compare cancer (ICD10 C00-97, excluding C44) incidence in two groups: 6805 burn injury patients discharged from Scottish hospitals between 2009 and 2019, and 25,946 subjects from the general population who were matched to burn patients by sex, year of birth, and degree of social deprivation. Cancer incidence was identified from the Scottish cancer registry. Cox proportional hazard regression was used to model time to cancer incidence adjusting for age, sex, degree of deprivation and presence of a comorbidity. Cancer risk was presented as standardised incidence ratios (SIRs) and hazard ratios (HR). RESULTS: We found a higher prevalence of pre-existing conditions, particularly alcohol abuse among patients with burns. Pre-existing cancers were more common in the burn cohort (3.5%) than the comparison group (1.7%) and were excluded from further analysis. Over a median follow-up of 4-5 years, a total of 236 (3.5%) burn patients and 969 (3.7%) persons in the comparison group were diagnosed with cancer. At 0-6 months the cancer SIR for burn patients was 1.88 95% CI (1.40-2.52). After excluding the first six months of follow-up, the overall incidence of cancer was marginally elevated in burn patients (SIR 1.04, 95% CI 0.90-1.19, p = 0.62) and not statistically different from the incidence in comparison subjects (adjusted HR 1.03, 95% CI 0.88-1.21, p = 0.71). CONCLUSIONS: Patients that suffer burn injury have a higher incidence of cancer than the general population and a group matched by age, sex and degree of deprivation. A higher incidence of adverse health-related behaviours such as smoking, alcohol use and pre-existing health conditions among many patients that suffer a burn most likely explain this observed increase. Any persisting inflammatory or immune dysfunction following burn injury is unlikely to account for the increase in cancers in this study.

Prevalence of Burn Pit Associated Symptoms Among US Veterans Who Utilize Non-Veteran's Affairs Private Healthcare.

OBJECTIVE: Do the 3.5 million US veterans, who primarily utilize private healthcare, have similar burn pit exposure and disease compared to the VA Burn Pit registry? METHODS: This is an online volunteer survey of Gulf War and Post-9/11 veterans. RESULTS: Burn pit exposure had significantly higher odds of extremity numbness, aching pain and burning, asthma, chronic obstructive pulmonary disease, interstitial lung disease, constrictive bronchiolitis, pleuritis, and pulmonary fibrosis. Chi-square did not reveal a difference in burn pit exposure and cancer diagnoses. CONCLUSIONS: These data demonstrate increased risk of neurological symptoms associated with burn pit exposure, which are not covered in the 2022 federal Promise to Address Comprehensive Toxics Act. Additional data will allow for the continued review and consideration for future medical benefits.

The changing pattern of pediatric burns in a territory burn center before and during the COVID-19 pandemic in China: A retrospective study.

BACKGROUND: Pediatric burn patients are an essential part of burn populations. However, there is limited publicly available data on the epidemiological impact of COVID-19 on pediatric burns in China. OBJECTIVE: In this paper, pediatric burn patients admitted to the Department of Burn Surgery of the First Hospital of Jilin University before and during COVID-19 were retrospectively investigated to determine the impact of COVID-19 on pediatric burn inpatients. METHODS: The information of inpatients from July 2017 to December 2019 (pre-COVID-19 group) and from January 2020 to June 2022 (COVID-19 group) in the Department of Burn Surgery at the First Hospital of Jilin University was retrospectively investigated. Demographic information of patients, length of hospital stay, total body surface area (TBSA) of burn injury, post-injury visit time, comorbidity, surgical methods, etc., were statistically analyzed. RESULTS: The COVID-19 group included 154 (10.2%) patients, and the pre-COVID-19 group included 335 (19.4%) patients (P＜0.001). There were no differences in gender, age, length of hospital stay, or etiology of burns between the two groups. Compared to the pre-COVID-19 group, patients in the pre-COVID-19 group experienced a significant delay in presentation (P＜0.001), had a larger TBSA of burn wound (P ＜ 0.001), were more prone to sustaining major burns (P ＜ 0.001), a higher likelihood of undergoing operations (P = 0.03), higher cost (P＜0.001) and more complications (P＜0.001). Additionally, upper extremities were the most commonly part involved in both groups (P = 0.004), with the lower extremities showed a significant increase to be involved in burn injury during COVID-19 pandemic (P = 0.007). Furthermore, the majority of guardians did not take first aid measures in both groups following burn injury (P = 0.102). CONCLUSIONS: During the COVID-19 pandemic period, scalds remained the main reason for hospitalization. The number of hospitalized patients has decreased dramatically, while the severity of burns has significantly increased, with a notable delay in hospital visits and an increased occurrence of complications.

Injury Pattern Analysis to Optimize Burn Injury Prevention in the Unhoused Community.

Unhoused patients are an overrepresented group in burn injury, and are a uniquely vulnerable population. Current research focuses on the consequences of homelessness on burn outcomes, with little known about the specific circumstances and behaviors leading to burn injury that may represent specific targets for injury prevention efforts. The burn registry at an urban regional burn center was queried for burn admissions in unhoused adults from 2019 to 2022. Registry data pulled included demographics, urine toxicology, mechanism of injury, and injury subjective history. Subjective injury history was reviewed to determine more specific injury circumstances and activities during which accidental burns occurred. Demographic and mechanistic trends in burn admissions were explored via descriptive statistics. Among 254 admissions for burns from the unhoused community, 58.1% of patients were positive for stimulants on admission. Among accidental injuries (69.7%), common circumstances included preparing food or beverages, cooking or using methamphetamine, smoking cannabis or tobacco, bonfires, and candles. A specific common circumstance was lighting a cigarette while handling accelerants (6.7%). Interventions for stimulant abuse, as well as outreach efforts to educate unhoused patients about situational awareness, safe handling of accelerants, safe smoking practices, and safe cooking practices, may be effective tools in reducing burn admissions in this vulnerable population.

Prevalence of anxiety and its risk factors in burn patients: A systematic review and meta-analysis.

The primary objective of this systematic review and meta-analysis was to ascertain the prevalence of anxiety and identify associated risk factors among individuals who have suffered burn injuries. We conducted a thorough and systematic search across various international electronic databases, including Scopus, PubMed and Web of Science, as well as Persian electronic databases like Iranmedex and the scientific information database (SID). Our search encompassed the period from the earliest available records up to 8 August 2023. We employed keywords derived from Medical Subject Headings (MeSH) such as "Prevalence", "Anxiety" and "Burns". In total, 2586 burn patients participated in 13 cross-sectional studies. The mean age of the participants was 32.88 (SD = 2.51). In a compilation of 13 studies, the documented overall occurrence rate of anxiety among burn patients stood at 16.1% (95% CI: 10.0% to 24.7%; I2 = 93.138%; p < 0.001). The outcomes of a meta-regression analysis, which examined the association between anxiety in burn patients and the year of publication, did not uncover any significant correlation (p = 0.442). Furthermore, there was a notable association between anxiety in burn patients and factors such as gender, TBSA affected, educational level and the types of burn injuries. Therefore, healthcare providers need to recognize the substantial prevalence of anxiety in burn patients as a fundamental consideration. This recognition should prompt a proactive approach toward early detection and timely intervention. Developing personalized intervention strategies tailored to each patient's unique risk factors and needs is paramount. These strategies may encompass a range of therapeutic options such as counselling, psychotherapy or consultations with mental health specialists.

Effect of vitamin D on clinical outcomes in patients with thermal injury.

Evaluating complications and mortality risks in burn patients is crucial for effective treatment planning and improving survival rates. This study investigated the relationship between the serum vitamin D level and the clinical outcomes of adult burns patients. This was a prospective cohort of adult patients hospitalized due to thermal burns at a burn centre in the north of Iran. Based on the level of 25 hydroxyvitamin D measured upon admission, patients were divided into two groups of patients with sufficient 25 hydroxyvitamin D level and insufficient 25 hydroxyvitamin D level. Descriptive statistics were used for baseline demographics. Univariate analysis was conducted using Mann-Whitney U, Chi-square, independent samples, and Fisher's exact tests. A multivariate logistic regression was performed to adjust for the effects of confounding variables. Statistical analyses were conducted using SPSS 28.0 software. A total of 220 patients were included in the study. The average total body surface area burned was 30.52 ± 9.34. Patients with insufficient vitamin D levels had longer hospital stays (12.53 vs. 11.45) and longer stays in the intensive care unit (ICU) (3.32 vs. 2.40) than those with appropriate vitamin D levels. Participants with insufficient vitamin D levels exhibited a numerically higher incidence of infections than those with adequate levels (p < 0.05). The multivariate regression found that vitamin D deficiency levels were associated with increased infection rates and prolonged hospital stay. This study suggests that vitamin D deficiency is a significant risk factor for adverse clinical outcomes in burn patients. Further research is needed to confirm these associations and to explore potential interventions to optimize vitamin D status in this patient population.

Machine learning identifies esophageal luminal temperature patterns associated with thermal injury in catheter ablation for atrial fibrillation.

INTRODUCTION: Luminal esophageal temperature (LET) monitoring during atrial fibrillation (AF) ablation is widely used to reduce the incidence of endoscopically detected esophageal lesion (EDEL). We sought to assess whether specific patterns of LET variation are associated with EDEL. METHODS: A high-fidelity multisensor probe was used to record LET in AF patients undergoing radiofrequency ablation (RFA) or cryoballoon ablation (CBA). Explainable machine learning and SHapley Additive exPlanations (SHAP) analysis were used to predict EDEL and assess feature importance. RESULTS: A total of 94 patients (38.3% persistent AF, 71.3% male, 72 RFA, and 22 CBA) were included. EDEL was detected in 11 patients (10 RFA and one CBA). In the RFA group, the highest LET recorded was similar between patients with and without EDEL (40.6 [40.1-41]°C vs. 40.2 [39.1-40.9]°C; p = .313), however, the rate of LET rise for the highest recorded peak was higher (0.08 [0.03-0.12]°C/s vs. 0.02 [0.01-0.05]°C/s; p = .033), and the area under the curve (AUC) for the highest peak was smaller (412.5 [206.8-634.1] vs. 588.6 [380.4-861.1]; p = .047) in patients who had EDEL. In case of CBA, the patient with EDEL had a faster LET decline (0.12 vs. 0.07 [0.02-0.14]°C/s), and a smaller AUC for the lowest trough (2491.3 vs. 2629.3 [1712.6-5283.2]). SHAP analysis revealed that a rate of LET change higher than 0.05°C/s and an AUC less than 600 were more predictive of EDEL in RFA. CONCLUSION: The rate of LET change and AUC for the recorded temperature predicted EDEL, whereas absolute peak temperatures did not.

Cold burn injuries in the United Kingdom: retain-->A 5-year cohort study of patients presenting to a regional burn unit.

AIMS: To assess the aetiology, management and outcomes of cold burn injuries presenting to a regional burn unit in the United Kingdom. METHODS: Retrospective cohort study of consecutive patients over a 5-year period (2018-2022). RESULTS: Sixty-two patients (M:F 34:38; median age 23.5 years) were identified. The most common aetiology was aerosol (n = 28, 45.2%). Seven (11.5%) injuries were sustained during a social media or peer 'challenge' and 19 (31.2%) were self-harm, of whom 5 (26.3%) were inpatients on a mental health ward at the time of injury. All 'challenge' and self-harm injuries were caused by aerosol. Patients with 'challenge' injury were younger than those with self-harm (p = .007) and non-intentional injuries (p < .001). A greater proportion of self-harm injuries were in female patients compared with non-intentional injuries (p < .001). Median total body surface area (TBSA) was 0.35% (IQR: 0.3). Most burns were superficial partial thickness (n = 35, 56.5%), followed by deep dermal (n = 18, 29.0%), full-thickness (n = 8, 12.9%), and superficial (n = 1, 1.6%). The upper limb was most frequently affected (n = 35, 56.5%). Aetiology and a non-intentional, 'challenge' or self-harm injury did not affect TBSA (p = 0.776 and p = 0.364) or depth (p = 0.353 and p = 0.381). Five (8.1%) patients underwent autografting. The median time to healing was 17 days (range: 7-45, IQR: 22.75). Follow-up ranged from 1 to 173 weeks. CONCLUSIONS: The incidence of cold burns has increased when compared with previous literature. A disproportionate number of cold burns are self-inflicted using aerosols, either as self-harm or because of social media or peer 'challenges'. Other emerging aetiologies include non-intentional skin contact with nitrous oxide containers during its recreational use.

Drug susceptibility, Prevalence and effect of Pseudomonas aeruginosa on wound healing of burn patients.

Objective: To determine the prevalence, antibiotic susceptibility and effect of Pseudomonas aeruginosa in relation to burn patients. METHODS: The cross-sectional study was conducted at the Centre for Advanced Studies in Vaccinology and Biotechnology, University of Balochistan, Quetta, Pakistan, from March 2018 to May 2021, and comprised pus swab cultures were isolated from inpatients with 2nd and 3rd degree burns aged up to 60 years at Bolan Medical Complex Hospital and Sandeman Provinical Hospital, the two main government tertiary care hospitals in Quetta. The samples were immediately cultured, and evaluated using biochemical tests, antibiotic susceptibility and molecular identification using polymerase chain reaction. Data was analysed using SPSS 20. RESULTS: Of the 720 burn wound samples, 424(58.9%) were positive for Pseudomonas aeruginosa; 304(42%) males and 120(16%) females (p<0.02). The overall mean age of the patients was 27.7±6.2 years (range: 1-60 years). The mean total burn surface area was not significantly different in positive 29.6±6.2% and negative 30.3±6.2% cases (p>0.05). The time leading to skin grafts in positive patients was 29.5±6.5 days compared to 22.3±6.3 days for negative patients (p< 0.007), and the time required for wound healing was 25.0±4.7 days and 16.7±5.2 days, respectively (p<0.001). Length of hospital stay of Pseudomonas aeruginosa positive patients was 38.0±7.8 days compared to 32.1±6.8 days for negative patients (p<0.001). Conclusion: Nosocomial infections and multidrug resistance species were observed frequently at the burn wound site. P. aeruginosa.

Development of an electronic burns register: Digitisation of routinely collected hospital data for global burns surveillance.

INTRODUCTION: Burn registers provide important data that can track injury trends and evaluate services. Burn registers are concentrated in high-income countries, but most burn injuries occur in low- and middle-income countries where surveillance data are limited. Injury surveillance guidance recommends utilisation of existing routinely collected data where data quality is adequate, but there is a lack of guidance on how to achieve this. Our aim was to develop a rigorous and reproducible method to establish an electronic burn register from existing routinely collected data that can be implemented in low resource settings. METHODS: Data quality of handwritten routinely collected records (register books) from a tertiary government hospital burn unit in Mysore, India was assessed prior to digitisation. Process mapping was conducted for burn patient presentations. Register and casualty records were compared to assess the case ascertainment rate. Register books from February 2016 to February 2022 were scanned and anonymised. Scans were quality checked and stored securely. An online data entry form was developed. All data underwent double verification. RESULTS: Process mapping suggested data were reliable, and case ascertainment was 95%. 1930 presentations were recorded in the registers, representing 0.84% of hospital all-cause admissions. 388 pages were scanned with 4.4% requiring rescanning due to quality problems. Two-step verification estimated there to be errors remaining in 0.06% of fields following data entry. CONCLUSION: We have described, using the example of a newly established electronic register in India, methods to assess the suitability and reliability of existing routinely collected data for surveillance purposes, to digitise handwritten data, and to quantify error during the digitisation process. The methods are likely to be of particular interest to burn units in countries with no active national burns register. We strongly recommend mobilisation of resources for digitisation of existing high quality routinely collected data as an important step towards developing burn surveillance systems in low resource settings.

Thromboembolic events in burn patients: An analysis of risk factors and different anticoagulants.

BACKGROUND: Burn patients are in a state of activated coagulation, putting them at risk for thromboembolic events. Additionally, certain patient-related factors are associated with an increased risk of thrombus formation. This study aimed to evaluate the incidence of thromboembolic events and identify potential risk factors, including patient characteristics, surgical treatment, anticoagulation strategies, and laboratory parameters. METHODS: A single-centre retrospective cohort study was conducted on all patients with burns treated between 2002 and 2020. Medical reports of patients with and without thromboembolic events were descriptively analysed. The association of time to thromboembolic events with total body surface area (TBSA) was assessed by cause-specific Cox models adjusted for different covariates. The association of time to thromboembolic events with type and dosage of anticoagulants was assessed using a cause-specific Cox proportional hazards model with time-dependent covariates, applied to a matched subset of patients. RESULTS: The incidence of thromboembolic events was 8.1% in a cohort of 642 patients. We found a statistically significant increase in the hazard for thromboembolic events by a factor of 1.02 (95% CI 1.00 to 1.03; P ≤ 0.05) per percent increase in TBSA. We identified former alcohol abuse (HR=2.54, CI 1.33 to 4.84, P = 0.005) and higher body mass index (HR=1.06, 95% CI 1.00 to 1.12, P = 0.046) as potential risk factors for the development of thromboembolic events. We further noted inadequate median anti-Factor-X activity levels and elevated C-reactive protein and procalcitonin levels at the time of the event. CONCLUSION: Our results showed a moderate risk of thromboembolic events among burn patients, underlining the importance of close monitoring with regard to thrombus formation. In particular, patients with higher TBSA, alcohol abuse and BMI may be evaluated more regularly for thromboembolic events. Anti-Factor-X activity levels should be determined regularly and therapy should be adjusted if necessary.

Post-traumatic stress disorder in burn patients - A large database analysis.

INTRODUCTION: Post-traumatic stress disorder (PTSD) afflicts a significant portion of burn patients. This study aims to analyze the morbidity, prevalence, and treatment of PTSD in the burn population. METHODS: Using the TriNetX database, we identified burned patients > 18 years of age without (A) or with (B) a PTSD diagnosis. Patients were then stratified by percent of total body surface area (TBSA) burned. Morbidity and mortality was analyzed in each cohort. Prevalence and pharmacologic treatments for PTSD were analyzed from 2002 to 2022. RESULTS: PTSD incidence increased from 2.4% (n = 2281) in patients with < 10% to 3.1% (n = 542) in 10-30%, 7.4% (n = 285) in 30-59%, and 5.3% (n = 90) in > 60% TBSA burned. In patients with < 60% TBSA burned, PTSD diagnosis increased the risk of depression (p = <0.0003) and anxiety (p = <0.0001). In those with < 30% TBSA burned, PTSD diagnosis also increased risk of insomnia (p = <0.0001) and pruritus (p = 0.0211 for TBSA <10% and 0.0059 for TBSA 10-29%). PTSD diagnosis was associated with a decreased risk of mortality in patients with > 30% TBSA burned (p = 0.0179 for TBSA 30-59% and p = 0.0089 for TBSA >60%). From 2002 to 2022, the prevalence of PTSD in all burn patients was relatively stable between 2.2% and 3.2%. We found an increase in the use of serotonergic agents and prazosin for the treatment of PTSD during this timeframe. CONCLUSION: PTSD is not uncommon in the burn population, and those with burns and concomitant PTSD have an increased risk of morbidity. Screening and preventative measures to reduce morbidity and early implementation of care in burned patients with PTSD are indicated.

Aetiology of bioethanol related burn accidents: A qualitative study.

BACKGROUND: Since insight into the motivation of behaviour in bioethanol related burn accidents is lacking, this study aimed to qualitatively examine influencing factors in bioethanol related burn accidents. In order to identify target points for effective burn prevention. METHODS: Patients previously admitted with bioethanol related acute non-intentional burn injury to the three Dutch burn centres were eligible. One interviewer conducted fourteen semi-structured interviews. Interviews were transcribed and coded by two independent researchers. Conclusions were drawn based on generalised statements on the concerned topics. RESULTS: Four overall themes in influencing factors were found, namely 1) motivation; including non-designated use and impaired judgement, 2) knowledge and education; including unknown product and properties and information overload, 3) risk perception; including poor recognisability of risks and preferred trial and error and 4) thresholds; including easy availability and unclear liability. CONCLUSION: Trust in consumers may be over-estimated, as proper use cannot be expected. To prevent future bioethanol related burn incidents, thresholds for obtaining and using bioethanol should be increased, safe alternatives to ignite open fires and wood stoves should be provided and knowledge and warnings should be improved.

An outbreak of multi-drug-resistant Acinetobacter baumannii on a burns ICU and its control with multi-faceted containment measures.

BACKGROUND: Patients in burns centres are at high risk of acquiring multi-drug-resistant organisms (MDROs) due to the reduced skin barrier and long hospital stay. METHODS: This study reports the investigation and control of an outbreak of MDR Acinetobacter baumannii in a burns centre. The 27 patients hospitalized in the centre during the outbreak were screened regularly, and a total of 132 environmental samples were analysed to identify a potential source. Fourier-transform infra-red (FT-IR) spectroscopy and multi-locus sequence typing were applied to characterize the outbreak strain. RESULTS: Between August and November 2022, the outbreak affected eight patients, with 11 infections and three potentially related fatal outcomes. An interdisciplinary and multi-professional outbreak team implemented a bundle strategy with repetitive admission stops, isolation precaution measures, patient screenings, enhanced cleaning and disinfection, and staff education. FT-IR spectroscopy suggested that the outbreak started from a patient who had been repatriated 1 month previously from a country with high prevalence of MDR A. baumannii. Environmental sampling did not identify a common source. Acquisition of the outbreak strain was associated with a higher percentage of body surface area with burn lesions ≥2a [per percent increase: odds ratio (OR) 1.05, 95% confidence interval (CI) 0.99-1.12; P=0.09], and inversely associated with a higher nurse-to-patient ratio (per 0.1 increase: OR 0.34, 95% CI 0.10-1.12; P=0.06). CONCLUSIONS: Burn patients with a higher percentage of body surface area with burn lesions ≥2a are at high risk of colonization and infection due to MDROs, particularly during periods of high workload. A multi-faceted containment strategy can successfully control outbreaks due to MDR A. baumannii in a burns centre.
