Epidemiological Characteristics

Background: Burn injury is one of the major causes of morbidity and mortality in our country. Study of epidemiological characteristics of burn injury helps in planning of the prevention and upgradation of its treatment facility. Material and Methods: This is a hospital based retrospective epidemiological study of the burn patients admitted in our center from September 2018 to April 2019. Results: In total 52 patients were included in this study. There was a slight preponderance of female patients over male patients. Mean age of the patients was 34.77± 29.16 years. Eighty percentage of burn injury occurred inside house. Majority of burn cases were scald burn followed by flame burn. Percentage total body surface area involved in burn had a mean of 14.183 ± 8.224. Lower extremity was the most commonly involved area. Total duration of hospital stay was 18.21 ± 13.656 days. Out of total patients only four patients needed admission in Intensive Care Unit (ICU). Regarding outcome, 88.5% patients survived while 9.6% patients died and 1.9% patient went on discharge on request. Conclusion: Burn injury is a preventable condition with high rate of morbidity and mortality. Burn patients have prolonged hospital stay as recovery is slow. Awareness programs for prevention of burn injury are needed to decrease the incidence of the burn injury.

Aim: To determine major risk factors of mortality and causes of death in patients presented with burn injury. Study design:Prospective Descriptive Study. Setting and duration: Department of Burns and Plastic Surgery, Khyber Teaching Hospital, Peshawar,Pakistan from April 2008 and June 2012. Methodology: A prospective descriptive study was performed among the patients whoadmitted to the Department of Burns and Plastic Surgery, Khyber Teaching Hospital, Peshawar, Pakistan between April 2008 and June2012. All relative information was collected through a detailed proforma and patient’s treatment files. Patients of any age, any degree ofburns and burns exceeding 10% TBSA were included. Patients presenting after more than one week post burn or patients referred fromother hospitals were excluded. Within this period, demographic data, treatment, and outcomes of treatment were reviewed and analyzed.Survivors and non-survivors among burn patients were compared to define the predictive factors of mortality. Results: Between April2008 and June 2012, 1850 patients were admitted with burn injuries. There were 1150 male patients (62%) and 700 female patients(38%). Mean age was 36 years with range of 1-70 years. Inhalation injuries were present in 45 patients (2.40%). Causes were flameburns (65.0%), electrical burns (15%), scalds (13%) and chemical burns (7.0%). The total body surface area (TBSA) burn ranged from10- 100%, with a mean of 38% TBSA burn. Mean length of hospital stay was 12 days (ranging from 24 hours to 170 days). Mortality ratewas 11.2%. Higher age, larger burn area, wound infection, longer hospital stay and the presence of multi-system organ failuresignificantly predicted increased mortality. Conclusions: Prevention is a key factor in reducing the morbidity and mor tality associatedwith burn injury. A campaign to educate people that burns can be prevented will be important in our community. The prevention of multiorganfailure and septicemia are likely to be more effective than their treatment.

Abstract Introduction In burn patients, vitamin D deficiency has been associated with increased incidence of sepsis. The objective of this study was to assess the impact of vitamin D deficiency in adult burn patients on hospital length of stay (LOS). Methods This was a multi-center retrospective study of adult patients at 7 burn centers admitted between January 1, 2016 and July 25, 2019 who had a 25-hydroxyvitamin D (25OHD) concentration drawn within the first 7 days of injury. Patients were excluded if admitted for a non-burn injury, total body surface area (TBSA) burn less than 5%, pregnant, incarcerated, or made comfort care or expired within 48 hours of admission. The primary endpoint was to compare hospital LOS between burn patients with vitamin D deficiency (defined as 25OHD < 20 ng/mL) and sufficiency (25OHD ≥ 20 ng/mL). Secondary endpoints include in-hospital mortality, ventilator-free days of the first 28, renal replacement therapy (RRT), length of ICU stay, and days requiring vasopressors. Additional data collected included demographics, Charlson Comorbidity Index, injury characteristics, form of vitamin D received (ergocalciferol or cholecalciferol) and dosing during admission, timing of vitamin D initiation, and form of nutrition provided. Dichotomous variables were compared via Chi-square test. Continuous data were compared via student t-test or Mann-Whitney U test. Univariable linear regression was utilized to identify variables associated with LOS (p < 0.05) to analyze further. Cox Proportional Hazard Model was utilized to analyze association with LOS, while censoring for death, and controlling for TBSA, age, presence of inhalation injury, and potential for a center effect. Results Of 1,147 patients screened, 412 were included. Fifty-seven percent were vitamin D deficient. Patients with vitamin D deficiency had longer LOS (18.0 vs 12.0 days, p < 0.001), acute kidney injury (AKI) requiring RRT (7.3 vs 1.7%, p = 0.009), more days requiring vasopressors (mean 1.24 vs 0.58 days, p = 0.008), and fewer ventilator free days of the first 28 days (mean 22.9 vs 25.1, p < 0.001). Univariable analysis identified burn center, AKI, TBSA, inhalation injury, admission concentration, days until concentration drawn, days until initiating supplementation, and dose as significantly associated with LOS. After controlling for center, TBSA, age, and inhalation injury, the best fit model included only deficiency and days until vitamin D initiation. Conclusions Patients with thermal injuries and vitamin D deficiency on admission have increased length of stay and worsened clinical outcomes as compared to patients with sufficient vitamin D concentrations.

Association between Procalcitonin (PCT) and C-reactive protein (CRP) and burn injury was evaluated in 80 burned patients from Al-Kindy and Imam Ali hospitals in Baghdad-Iraq. Patients were divided into two groups, survivor group 56 (70%) and non-survivor group 24 (30%). PCT was estimated using (Human Procalcitonin ELISA kit) provided by RayBio/USA while CRP was performed using a latex agglutination kit from Chromatest (Spain). Our results declared that the mean of Total Body Surface Area (TBSA %) affected were 63.5% range (36%–95%) in non-survivor patients, while 26.5% range (10%–70%) in survivor patients. There is a significant difference between the two groups (P = 0.00), the higher mean percentage of TBSA has a significant association with mortality. Serum PCT and CRP were measured at the three times of sampling (within the first 48hr following admission, after 5thdays and after 10th days). The mean of PCT serum concentrations in non-survivor group (2638 ± 3013pg/ml) were higher than that of survivor group (588 ± 364pg/ml). Significantly high levels of CRP were found between the survivor and non-survivor groups especially in the 10th day of admission P=0.000, present study show that significant differences is found within the non-survivor group through the three times P= 0.01, while results were near to significant differences within survivor group through the three times (P= 0.05).

Abstract Introduction Oxandrolone is an anabolic steroid that is the standard of care for burn patients experiencing hypermetabolism. Previous studies have demonstrated the benefits of oxandrolone, including increased body mass and improved wound healing. One of the common side effects of oxandrolone is transaminitis, occurring in 5–15% of patients, but little is known about associated risk factors with the development of transaminitis. A recent multicenter study in adults found that younger age and those receiving concurrent intravenous vasopressors or amiodarone were more likely to develop transaminitis while on oxandrolone. The purpose of this study was to determine the incidence and identify risk factors for the development of transaminitis in pediatric burn patients receiving oxandrolone therapy. Methods This was a multicenter, retrospective risk factor analysis that included pediatric patients with thermal burn injury (total body surface area [TBSA] > 10%) who received oxandrolone over a 5-year time period. The primary outcome of the study was the development of transaminitis while on oxandrolone therapy, which was defined as aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >100 mg/dL. Secondary outcomes included mortality, length of stay, and change from baseline ALT/AST. Results A total of 55 pediatric patients from 5 burn centers met inclusion criteria. Of those, 13 (23.6%) developed transaminitis, and the mean time to development of transaminitis was 17 days. Patients who developed transaminitis were older (12 vs 6.4 years, p = 0.01) and had a larger mean %TBSA (45.9 vs 34.1, p = 0.03). The odds of developing transaminitis increased by 23% for each 1 year increase in age (OR 1.23, CI 1.06–1.44). The use of other concurrent medications was not associated with an increased risk of developing transaminitis. Renal function and hepatic function was not associated with the development of transaminitis. There was no significant difference in length of stay and mortality. Conclusions Transaminitis occurred in 23.6% of our study population and was associated with patients who were older and had a larger mean %TBSA burn. Older pediatric patients with larger burns who are receiving oxandrolone should be closely monitored for the development of transaminitis. Applicability of Research to Practice Future research is needed to identify appropriate monitoring and management of transaminitis in oxandrolone-treated pediatric burn patients.

Epidemiological Characteristics

Introduction: Burn injury remains one of the biggest health concerns in the developing world. It has been regarded as a formidable public health issue in terms of mortality, morbidity and permanent disability. We aim to provide an overview of the basic epidemiological characteristics of burn patients admitted at a dedicated burn center in Chitwan, Nepal. Methods: This was a retrospective, hospital-based observational study conducted at Chitwan Medical College Teaching Hospital (CMCTH) burn ward from September 2017 to August 2019. Patients’ records from admission/discharge book, admission/discharge summaries as well as patient’s individual files were reviewed to obtain the necessary data. Demographic data, clinical characteristics, treatments and outcomes were statistically analyzed. Results: Among the 202 patients, the number of males slightly predominated that of females with a ratio of 1.02:1. The median age was 24 years, and the median total body surface area (TBSA) burned was 15%.  Children less than 10 years comprised one third of all patients while more than one fifth were elderly. The commonest etiological factor was flame burn, closely followed by scald. The mortality rate was 12.38% for the period under review. Majority of the patients spent less than 10 days on admission and around one fifth needed surgical intervention aimed at earlier coverage. Binary logistic regression analysis showed that age, Body Mass Index (BMI) and total body surface area (TBSA) burnt were the major predictors of burn mortality. Conclusions: The outcome of burn injuries is poor. Appropriate preventive & therapeutic measures need to be taken in terms of social education & provision of quality healthcare to reduce the incidence & improve the survival outcome of burn patients which should focus on children and elderly especially during the winter season.

AbstractNutrition therapy is considered an important treatment of burn patients. The aim of the study was to delineate the nutritional support in severe burn patients and to investigate association between nutritional practice and clinical outcomes. Severe burn patients were enrolled (n 100). In 90 % of the cases, the burn injury covered above 70 % of the total body surface area. Mean interval from injury to nutrition start was 2·4 (sd 1·1) d. Sixty-seven patients were initiated with enteral nutrition (EN) with a median time of 1 d from injury to first feed. Twenty-two patients began with parenteral nutrition (PN). During the study, thirty-two patients developed EN intolerance. Patients received an average of about 70 % of prescribed energy and protein. Patients with EN providing <30 % energy had significantly higher 28- d and in-hospital mortality than patients with EN providing more than 30 % of energy. Mortality at 28 d was 11 % and in-hospital mortality was 45 %. Multiple regression analysis demonstrated that EN providing <30 % energy and septic shock were independent risk factors for 28- d prognosis. EN could be initiated early in severe burn patients. Majority patients needed PN supplementation for energy requirement and EN feeding intolerance. Post-pyloric feeding is more efficient than gastric feeding in EN tolerance and energy supplement. It is difficult for severe burn patients to obtain enough feeding, especially in the early stage of the disease. More than 2 weeks of underfeeding is harmful to recovery.

Abstract Introduction Acute kidney injury (AKI) in burn patients is known to increase morbidity and mortality, with significant improvement after the initiation of renal replacement therapy (RRT). Our primary objective is to characterize the sub-population of burn patients with early (≤48 hours post-injury) versus late (>48 hours post injury) onset of AKI. We hypothesize that patients with early onset AKI versus late onset AKI have different causalities, risk factors, and outcomes. A secondary aim is to investigate the timing and use of RRT in the setting of early and late AKI with the goal of improving morbidity and mortality. Methods A retrospective cohort study was conducted on all patients admitted to a verified burn center requiring RRT for AKI from 2015 – 2019. Patients were stratified by age, gender, percent total body surface area (TBSA), race, time of onset of AKI, timing of RRT initiation, hospital LOS, pre-admission co-morbidities, admission toxicology, and mortality. Results In total, 1537 burn patients were reviewed and 1.3% (n=20) required RRT for AKI. Out of this cohort, 70% developed early AKI and 30% developed late AKI. Early versus late AKI patients had the same median age (57). Patients with larger TBSA developed early AKI (median TBSA 51%) versus late AKI (median TBSA 21%). Half of the patients who developed late AKI presented with positive alcohol toxicology screens, while 86% of patients with early AKI tested negative. The patient mortality rate in early AKI was 57%, and the mortality rate in late AKI was 17%. Only 14% of early AKI patients required dialysis at discharge, while 33% of late AKI patients required dialysis at discharge. The majority of patients started on early RRT (< 48 hours post injury) did not develop sepsis (43% developed sepsis), while the majority of patients started on late RRT (>48 hours post injury) did develop sepsis (85%). Conclusions Positivity for alcohol on admission may be a predictor for development of late AKI, while larger TBSA may predict early AKI. Mortality is higher for patients with early AKI; however, the need for dialysis at discharge is higher in patients with late AKI. Our data further suggests that early initiation of RRT is negatively correlated with the development of sepsis. Applicability of Research to Practice A deeper understanding of associations and causality of early vs late onset AKI in burn patients will help guide further management and improve outcomes.

Abstract Introduction Cardiac dysfunction can develop in large pediatric burns during the acute and recovery phase. When occurring in this population, the cardiac abnormality appears as left ventricular dysfunction or dilated cardiomyopathy. Recent studies have demonstrated perioperative and long-term cardiac dysfunction resulting in longer hospital stays for patients over 40% total body surface area. The objective of this study was to assess if early use of echocardiograms in large burns would allow for early recognition of patients at risk for cardiac dysfunction. Material and Methods Pediatric burn patients ages 0-18 years who sustained a burn injury of 30% TBSA or more or developed cardiac dysfunction during hospital course were evaluated. Echocardiograms were obtained upon admission with monthly repeats until three normal studies were attained or the patient was discharged and when symptomatic. Results Of the 130 acute burn patients admitted during 7/2017-10/2018, 10 patients met criteria for enrollment in this study. The average age was 5 years (0.8 to 10 yrs), 70% were males and 90% sustained flame injuries.Total TBSA average was 45% (24-70%) with average full thickness burns of 33% (0-67%). Twenty echocardiogram studies were obtained. One patient with 25% TBSA burn, demonstrated severe left ventricular dysfunction with an EF of 25% from post arrest myocardial stunning. Repeat echocardiogram studies demonstrated full recovery with normal EF. The remaining patients, despite large TBSA injuries, did not exhibit any abnormalities on ECHO examinations. No cardiac interventions were required. Conclusions Use of echocardiograms is best performed on symptomatic burn patient populations.

OBJECTIVEBurn patients are particularly vulnerable to infection, and an estimated half of all burn deaths are due to infections. This study explored risk factors for healthcare-associated infections (HAIs) in adult burn patients.DESIGNRetrospective cohort study.SETTINGTertiary-care burn center.PATIENTSAdults (≥18 years old) admitted with burn injury for at least 2 days between 2004 and 2013.METHODSHAIs were determined in real-time by infection preventionists using Centers for Disease Control and Prevention criteria. Multivariable Cox proportional hazards regression was used to estimate the direct effect of each risk factor on time to HAI, with inverse probability of censor weights to address potentially informative censoring. Effect measure modification by burn size was also assessed.RESULTSOverall, 4,426 patients met inclusion criteria, and 349 (7.9%) patients had at least 1 HAI within 60 days of admission. Compared to <5% total body surface area (TBSA), patients with 5%–10% TBSA were almost 3 times as likely to acquire an HAI (hazard ratio [HR], 2.92; 95% CI, 1.63–5.23); patients with 10%–20% TBSA were >6 times as likely to acquire an HAI (HR, 6.38; 95% CI, 3.64–11.17); and patients with >20% TBSA were >10 times as likely to acquire an HAI (HR, 10.33; 95% CI, 5.74–18.60). Patients with inhalational injury were 1.5 times as likely to acquire an HAI (HR, 1.61; 95% CI, 1.17–2.22). The effect of inhalational injury (P=.09) appeared to be larger among patients with ≤20% TBSA.CONCLUSIONSLarger burns and inhalational injury were associated with increased incidence of HAIs. Future research should use these risk factors to identify potential interventions.Infect Control Hosp Epidemiol 2017;38:1441–1448

Abstract Background With various changes implemented such as perioperative antibiotics for tangential excision, this retrospective study reviews the infection profile of burn patients at Singapore’s only centralized burns unit. Worldwide, the appearance of multidrug-resistant (MDR) strains of Acinetobacter baumannii (A. baumannii) continues to worsen patient outcomes. This study also surveys the role of blood cultures in burns at our unit. Methods Four hundred fifty-two burn patients admitted to the unit between 2011 and 2013, and with cultures performed, were included in the study. The yields of various cultures were evaluated and 2684 samples were amassed, of which 984 (36.7 %) were positive. Patient variables for predictors of MDR A. baumannii infection acquisition and bacteremia were evaluated through multivariate analyses. Results Pseuodomonas aeruginosa (P. aeruginosa) (67 patients) was the most common organism in those with total body surface area (TBSA) burn &lt;20 % while MDR A. baumannii (39 patients) was most prevalent in those with TBSA burn ≥20 %. We found a yield of 1.1 % positive blood cultures for TBSA burn &lt;20 % and a yield of 18.6 % positive cultures in TBSA burn ≥20 %. The median time between surgery and bacteremia was 6.5 days (range -18 to 68 days, interquartile range 4.5); 2.9 and 8.8 % of bacteremic episodes occurred within 24 and 48 h, respectively. This is a decrease from a predeceasing study (45.3 % for 24 h and 60 % for 48 h). Multivariate analysis revealed that length of hospital stay and TBSA burn ≥20 % were predictors of MDR A. baumannii infection and positive blood cultures. Conclusions MDR A. baumannii infection burdens patient management, especially in those with TBSA burn ≥20 % and longer hospital stay. Prophylactic antibiotics may reduce perioperative bacteremia, but their role in MDR infections needs to be evaluated. The role of blood cultures in TBSA burn &lt;20 % needs reconsideration.
