Treatment of Anaemia in Patients with Acute Burn Injury: A Study of Blood Transfusion Practices

Objective: To determine blood transfusion practices, risk factors, and outcomes associated with the use of blood products in the setting of the acute management of burn patients at the Victorian Adult Burn Service. Background: Patients with burn injuries have variable transfusion requirements, based on a multitude of factors. We reviewed all acute admissions to the Victorian Adult Burns Service (VABS) between 2011 and 2017: 1636 patients in total, of whom 948 had surgery and were the focus of our analysis. Method and results: Patient demographics, surgical management, transfusion details, and outcome parameters were collected and analyzed. A total of 175 patients out of the 948 who had surgery also had a blood transfusion, while 52% of transfusions occurred in the perioperative period. The median trigger haemoglobin in perioperative was 80mg/dL (IQR = 76–84.9 mg/dL), and in the non-perioperative setting was 77 mg/dL (IQR = 71.61–80.84 mg/dL). Age, gender, % total body surface area (TBSA) burn, number of surgeries, and intensive care unit and hospital length of stay were associated with transfusion. Conclusions: The use of blood transfusions is an essential component of the surgical management of major burns. As observed in our study, half of these transfusions are related to surgical procedures and may be influenced by the employment of blood conserving strategies. Furthermore, transfusion trigger levels in stable patients may be amenable to review and reduction. Risk adjusted analysis can support the implementation of blood transfusion as a useful quality indicator in burn care.

Abstract Blood transfusion in burns larger than 20% total body surface area (TBSA) are frequent due to operative procedures, blood sampling, and physiologic response to burn injury. Optimizing the use of blood transfusions requires an understanding of the physiology of burn injury, the risks and benefits of blood transfusion, and the indications for transfusion. Age also plays a role in determining blood transfusion requirements. Children in particular have a different physiology than adults, which needs to be considered prior to transfusing blood and blood products. This article describes the physiologic differences between children and adults in general and after burn injury and describes how these differences impact blood transfusion practices in children.

Recent data demonstrate a possible mortality benefit in traumatically injured patients when given subcutaneous recombinant human erythropoietin (rhEPO). The purpose of this report is to examine the effect of rhEPO on mortality and transfusion in burn patients. We conducted a review of burn patients (greater than 30% total body surface area, intensive care unit [ICU] days greater than 15) treated with 40,000u rhEPO over an 18-month period (January 2007 to July 2008). Matched historical controls were identified and a contemporaneous cohort of subjects not administered rhEPO was used for comparison (NrhEPO). Mortality, transfusions, ICU and hospital length of stay were assessed. A total of 105 patients were treated (25 rhEPO, 53 historical control group, 27 NrhEPO). Hospital transfusions (mean 13,704 ± mL vs 13,308 ± mL; P = 0.42) and mortality (29.6 vs 32.0%; P = 0.64) were similar. NrhEPO required more blood transfusions (13,308 ± mL vs 6,827 ± mL; P = 0.004). No difference in mortality for the rhEPO and NrhEPO (32.0 vs 22.2%; P = 0.43) was found. Thromboembolic complications were similar in all three groups. No effect was seen for rhEPO treatment on mortality or blood transfusion requirements in the severely burned.

Background Acute kidney injury (AKI) is one of the most severe complications of burn injury. AKI with severe burn injury causes high mortality. This study aims to investigate the incidence of and predisposing factors for AKI in burn patients. Methods This is a single-center, retrospective, descriptive criterion standard study conducted from June 27, 2015, to March 8, 2016. We used Kidney Disease Improving Global Outcomes criteria to define and select patients with AKI. The study was conducted by recruiting in hospital patients who suffered from the flammable cornstarch-based powder explosion and were treated under primary care procedures. A total of 49 patients who suffered from flammable dust explosion-related burn injury were enrolled and admitted on June 27, 2015. The patients with more than 20% total body surface area of burn were transferred to the intensive care unit. Patients received fluid resuscitation in the first 24 hours based on the Parkland formula. The primary measurements were the incidence of and predisposing factors for AKI in these patients. Demographic characteristics, laboratory data, and inpatient outcomes were also evaluated. The incidence of AKI in this cohort was 61.2% (n = 30). The mortality rate was 2.0% (n = 1) during a 59-day follow-up period. The multivariate analysis revealed inhalation injury (adjusted OR = 22.0; 95% CI [1.4–358.2]) and meeting ≥3 American Burn Association (ABA) sepsis criteria (adjusted OR = 13.7; 95% CI [1.7–110.5]) as independent risk factors for early advanced AKI. Conclusions The incidence rate of AKI was higher in this cohort than in previous studies, possibly due to the flammable dust explosion-related burn injury. However, the mortality was lower than that expected. In clinical practice, indicators of inflammation, including ABA sepsis criteria may help in predicting the risk of AKI in patients with burn injury.

Abstract Background Burn related injuries from natural disasters are not well described and natural disasters are not identified as an etiology of burn injury in the National Burn Repository (NBR) of the American Burn Association. The natural disaster Super Storm Hurricane Sandy had devastating effects. Our goal was to detail the burn related injuries following this natural disaster and to compare the data to the NBR. Methods This was a retrospective chart review of thirty four patients who sustained burn related injuries following Super Storm Hurricane Sandy (SSHS) and were managed at Staten Island University Hospital Burn Center. Institutional Review Board approval was obtained. Data variables included age, gender, race, past medical history (PMHx), burn type, percentage total body surface area (%TBSA), hospital length of stay (HLOS), and mortality. We compared data from SSHS to the 2003-2013 NBR. Categorical data were summarized using frequency counts, percentages and Clopper-Pearson 95 % confidence interval for proportion. Continuous outcome data were summarized by descriptive statistics. Data analyses performed with SAS® System Version 9.3 (SAS Institute Inc., Cary, NC) and p < 0.05 was significant. Results In the SSHS group, average age was 36 + 24 years, range 1-80 years, and 44.1 % were males (15/34, 95 % CI: 27.2 - 62.1). Caucasians comprised 58.8 %, (20/34, 95 % CI: 40.7, 75.4) and 73.5 % had no PMHx (25/34, 95 % CI: 55.6, 87.1). The most common burn type was scald, 55.9 %, (19/34, 95 % CI: 37.9, 72.8) and %TBSA ranged 1 %–47 %, average of 7 % + 12 %. The average HLOS was 13 + 26 days, range of 1–113 days. Mortality was 2.9 % (1/34, 95 % CI: 0.07–15). In comparison, the NBR reported an average age of 32 years and 69 % were males. Caucasians comprised 59.1 %. The most common burn type was flame, 43.2 % and the %TBSA ranged 1 %–9.9 %. HLOS ranged 8.4–10.2 days and mortality was 3.4 %. Conclusion We conclude that burn related injuries following a natural disaster differ as compared to those most commonly reported in the NBR.

Abstract Introduction Hospital length of stay is a measure of burn care quality and resource allocation. Traditionally, the average length of stay (LOS) for patients with burns is estimated at 1 day/% total body surface area (TBSA) although the 2016 American Burn Association National Burn Repository predicts closer to 3 days/%TBSA. Recent literature has shown that application of autologous skin cell suspension (ASCS) is associated with decreased hospital LOS and therefore is considered economically advantageous. Our study evaluated the LOS as it related to TBSA as well as the number of operations in patients treated with ASCS. Methods This is a single institution, retrospective review of burn patients at an American Burn Associated verified burn center admitted from August 2019 - August 2020 who underwent epidermal autografting. Patients were treated for partial thickness and full thickness burns either with epidermal grafting alone or in combination with widely meshed skin grafting. Demographics included age and sex of patient. The TBSA, LOS, number of operations, and re-admission rates were also collected. Results A total of 52 patients were included in the review. 73% were male with an average age of 42 years (range 15 months to 88 years. The patients were stratified into 4 different categories based on their burn TBSA: 0-10% (n=25), 11-20% (n=16), 21-30% (n=5), and >30% (n=6). The average number of operations increased with %TBSA (0-10%=1, 11-20%=1, 21-30%=2, >30%=4). The average LOS overall was 0.9 days/%TBSA (0-10%=1.0, 11-20%=0.7, 21-30%=0.9, >30%=0.8). Only one patient required re-admission after the first dressing takedown and underwent a second application of ASCS with subsequent healing. No patients required reconstructive surgery. Conclusions Burn patients treated with ASCS continue to demonstrate a decreased LOS/%TBSA and an overall decrease in the number of operations. The most significant impact may be noted as burn size increases.

Abstract Tent fires are a growing issue in regions with large homeless populations given the rise in homelessness within the US and existing data that suggest worse outcomes in this population. The aim of this study is to describe the characteristics and outcomes of tent fire burn injuries in the homeless population. A retrospective review was conducted involving two verified regional burn centers with patients admitted for tent fire burns between January 2015 and December 2020. Variables recorded include demographics, injury characteristics, hospital course, and patient outcomes. Sixty-nine patients met the study inclusion criteria. The most common mechanisms of injury were by portable stove accident, assault, and tobacco or methamphetamine-related. Median percent total body surface area (%TBSA) burned was 6% (IQR 9%). Maximum depth of injury was partial thickness in 65% (n=45) and full thickness in 35% (n=24) of patients. Burns to the upper and lower extremities were present in 87% and 54% of patients, respectively. Median hospital Length-of-Stay (LOS) was 10 days (IQR=10.5) and median ICU LOS was 1 day (IQR=5). Inhalation injury was present in 14% (n=10) of patients. Surgical intervention was required in 43% (n=30) of patients, which included excision, debridement, skin grafting, and escharotomy. In-hospital mortality occurred in 4% (n=3) of patients. Tent fire burns are severe enough to require inpatient and ICU level of care. A high proportion of injuries involved the extremities and pose significant barriers to functional recovery in this vulnerable population. Strategies to prevent these injuries are paramount.

Abstract Introduction With severe burn injury, there is systemic fluid loss due to inflammatory responses in damaged tissue, leading to disruption of cellular processes. Patient fluid levels are restored with the calculation of total body surface area (TBSA). Clinically used TBSA equations are often outdated and inaccurate with error up to 20%, resulting in misinformed treatment and subsequent sequelae including prolonged hospital length of stay and increased mortality. Our objective, therefore, was to create a point-of-care (POC) system employing 3D imaging technology to accurately calculate TBSA for all patient population varieties. Methods Our team employed an iPad attachable, infrared scanner to create 3D models of the human body. From these models, TBSA can be extrapolated using scan processing software. Subject scans were collected on our device and on a gold standard scanner for comparison of TBSA output. Clinical testing on burn patients is occurring at present to establish scanning precision of TBSA in the burn care environment. Results Non-clinical verification tests of the 3D scanned TBSA revealed a 4.05% error when compared to the gold standard, and precision error of 3.8%. Additionally, we introduced the device into the burn unit for preliminary testing with a physician user and non-patient subjects. The subjects were scanned in a prone position to mimic burn care workflow. Clinician scanning error was 1.41% when compared to the gold standard scan of the same subject. Clinical precision study results are on-going in collection. Conclusions Our device introduces an improved method of TBSA estimation to assist clinicians in making accurate burn care decisions and further precision medicine with greater anthropomteric data, notably for children. This device is one of the first POC-3D scanning technologies to be used in a burn setting and may also be employed at outlying medical facilities. Destructive wildfires and combat burn injuries highlight the need for such a device to standardize the triage of burn victims with and away from experienced medical staff. Applicability of Research to Practice 3D body mapping points to an enhanced method of TBSA calculation and minimally disruptive to the burn workflow. Future developments of 3D scanning include deep learning algorithms to identify and better assess burned surface area. Additionally, further automation of TBSA scan processing to reduce user error in calculation and improve burn injury outcomes.

Outcome Comparison

Introduction Within the United Kingdom’s major trauma networks, limited consideration is given to the management of concomitant burns and trauma injuries, prominently highlighted in the arrangement of specialist services for major trauma and burns care. The majority of the literature regarding this topic, based almost exclusively on North American studies, predicts between 5 and 7% of all patients admitted to burns centres will suffer from concomitant (non-thermal) trauma injuries, in addition to their burn injuries. The aim of this study is to understand the epidemiology and outcomes for patients sustaining burns and trauma injuries in England and Wales. Methods A retrospective review of patients sustaining concomitant burns and trauma injuries was made over a 71-month period from January 2010 to November 2016, using the national trauma registry for England and Wales, the Trauma Audit and Research Network database, identifying all patients with injury codes for burns and trauma (AIS >3). Data collected comprised patient demographic information, burn injury percentages, details of trauma injuries, details of hospital stay, and patient outcome. Comparison of information was made against the total burns and total trauma cohort to form a base standard for burns and trauma injuries, respectively. Results Over the period analysed, 188 patients were found to have concomitant burns and trauma injuries. The patients were stratified according to age and the percentage of total body surface area burned. Hospital length of stay for concomitant burns and trauma patients was found to be higher than that of patients with isolated burns injuries. Mortality rates, although low overall, were found to be relatively higher for patients with concomitant burns and trauma injuries. Conclusions This study demonstrated the rarity of this combination of injury pattern, in particular the occurrence of severe burns in the presence of major trauma, in UK. Improvements in burns care and trauma care hopefully contributes to the higher level of survival in concomitantly injured patients against data from previous literature. However, the synergistic effect of burns and trauma injuries appears to impact on the course of such patients, although larger scale analysis is required to determine the true prognostic factors.

Abstract Introduction Interleukin (IL)-6 is a multifunctional cytokine that has both a pro- and anti-inflammatory role. In many studies, IL-6 has been shown to increase rapidly after burn injury and is associated with poor outcomes. IL-6 can signal via its soluble IL-6 Receptor (sIL-6R) and is referred to as trans-signaling, which is regarded as the pro-inflammatory pathway. The role of sIL-6R post-burn injury has not yet been explored. We hypothesized that patients with a lower ratio of IL-6 to sIL-6R would have worse outcomes. Methods Patients admitted to our burn centre within 7 days of injury were included in this study. Patients were divided into two groups based on IL-6 and sIL-6R levels measured within the first 30 days post-burn injury. Patients were in the high ratio group if their IL-6:sIL-6R ratio was ≥ 0.185. Clinical outcomes included organ biomarkers, morbidities, and hospital length of stay. Groups were compared using Student’s t-test, Mann-Whitney U, and Fisher’s exact test as appropriate; a P value of < 0.05 was considered statistically significant. Results We studied 104 patients, mean age 51 ± 18 years and 24 ± 17% total body surface area (TBSA) burn. There were 49 patients categorized with a low IL-6:sIL-6R ratio and 55 patients with a high IL-6:sIL-6R ratio. Patients in the high IL-6:sIL-6R ratio group had a significantly greater TBSA burn and a significantly greater proportion of patients with inhalation injury (p< 0.05). Levels of sIL-6R were not significantly different among the low and high group (770 ± 264 pg/mL vs. 798 ± 268 pg/mL respectively; p=0.601). However, levels of IL-6 were significantly higher in patients with a high IL-6:sIL-6R ratio (37 IQR 19–97 pg/mL vs. 567 IQR 273–916 pg/mL; p< 0.0001). Mortality was significantly greater in the high IL-6:sIL-6R ratio group (2% vs. 27%; p< 0.001). Conclusions Interestingly, patients with a higher ratio of IL-6:sIL-6R had significantly greater mortality. Using sIL-6R as a marker for the proinflammatory immune response, we expected patients with a lower IL-6:sIL-6R ratio to have poor outcomes which are typically associated with a hyperinflammatory or exaggerated immune response. However, the absolute value of sIL-6R did not differ. This suggests that classic signaling of IL-6 via its membrane bound receptor, with an anti-inflammatory function, is an important factor. Applicability of Research to Practice The opposing pro- and anti-inflammatory function of IL-6 through trans- and classic signaling is contingent on the ratios expressed. The demonstrated increase in classic signaling highlights the importance of measuring both IL-6 and sIL-6R in future studies. Additionally, it lays the foundation for potential precision medicine approaches to selectively block specific signaling pathways.

Abstract Background Aboriginal and Torres Strait Islander children have higher incidence, severity and hospital length of stay for their acute burn injuries than other Australian children. We examined factors contributing to longer length of stay for Aboriginal and Torres Strait Islander children with an acute burn injury. Methods Burns Registry of Australia and New Zealand admissions of children < 16 years of age between October 2009 and July 2018 were analysed. Descriptive statistics explored patient and injury characteristics; Cox-regression models estimated characteristics associated with longer length of stay. Knowledge Interface methodology and Indigenous research methods were used throughout. Results A total of 723 children were identified as Aboriginal and Torres Strait Islander and 6257 as other Australian. The median hospital length of stay for Aboriginal and Torres Strait Islander children (5 days [CI 5–6]) was 4 days longer than other Australian children (1 day [CI 1–2]). Remoteness, flame burns, high percentage total body surface area (%TBSA) and full thickness burns were factors associated with longer length of stay for Aboriginal and Torres Strait Islander children. Similar prognostic factors were identified for other Australian children along with Streptococcus sp. and Staphylococcus sp. infection. Conclusion Remoteness, flame burns, %TBSA, and full thickness burns are prognostic factors contributing to extended hospital length of stay for all Australian children. These factors are more prevalent in Aboriginal and Torres Strait Islander children, impacting length of stay. Treatment programs, clinical guidelines, and burns policies should engage with the unique circumstances of Aboriginal and Torres Strait Islander children to mitigate inequities in health.
