Electrical burns in train climbers treated in the Helsinki Burn Centre during the last 30years.

Patients who climb onto the roof of a stationary train carriage and sustain a high voltage electrical injury from the overhead cables represent a rare type of electrical injury. The aim of this study was to review all the electrical burns and their outcomes in train climbers treated in the Helsinki Burn Centre during the last three decades. 18 patients who had climbed onto the roof of a stationary electric train between November 1993 and December 2022 were included. Trauma- and outcome-related variables were collected. The primary outcome endpoints were in-hospital mortality and major amputations. 16 (88.9%) patients were male. The median age was 15.5years (range: 13-29years). All the burns were high-voltage electrical burns. The mean burn size was 45% of the total body surface area. Three (16.7%) patients died in hospital. The mean length of the Burn Centre stay was 50days. On average, the patients underwent 5 operations (range: 0-32) during their inpatient stay. Three patients required major amputation. Eight of the patients underwent late operations. Seven (38.9%) patients exhibited late neurological dysfunction or neuropsychological symptoms at long term follow-up. In conclusion, train climbers represent a rare group of young patients with electrical burns. Precautionary strategies should be implemented to prevent these injuries that are associated with high morbidity and mortality.

A comprehensive nurse-led aftercare programme addressing post-burn sexual well-being of adult burn survivors: a randomised controlled trial.

Sexual well-being is a key part of being human yet often remains shrouded in secrecy and poorly addressed in the clinical setting. The impact of burns and its long-term sequelae often lead to concerns regarding body image disturbance, self-esteem issues, and interpersonal challenges which can impact on an individual's sexual well-being. However, existing post-burn rehabilitation programmes usually lack components addressing concerns regarding sexual well-being. As a part of a larger project, we developed a nurse-led aftercare programme, and this study sought to examine the effects of the programme in addressing the post-burn sexual well-being of adult burn survivors. A randomised controlled trial approach was used. Sixty burn survivors aged ≥ 18 years with burn size ≥ 10% total burn surface area were assigned to intervention and control groups. Participants in the intervention group underwent the nurse-led aftercare programme which involved pre-discharge support and proactive follow-up support over 8 weeks. The sexuality subscale of the Burn Specific Health Scale-Brief was used to evaluate the outcome of interest. Data were collected at three timepoints: baseline (T0), post-intervention (T1), and follow-up (T2). Using a corrected p value of 0.017, the study observed only statistically significant time effect at both T1 and T2. Both group and interaction effects were statistically insignificant for this outcome. Issues regarding sexual well-being are often considered sacred and may be challenging to discuss. Thus, a longer duration of the intervention may be considered with ongoing training of practitioners to identify and resolve emerging challenges. Despite the non-significant interaction and group effects, including sexual well-being support in post-burns rehabilitation programmes will facilitate access to and utilisation of the service among burn survivors who may need it.

Skin graft take rate among minor burns – A cohort study to investigate the effect of factors such as burn depth, burn size, and timing of the operation

BackgroundIt has been known for decades that early excision of burns reduces morbidity and mortality. Early surgical excision and skin grafting has become the most important part of successful healing in burn management, especially in major burns. However it is not entirely clear whether early excision and skin transplantation has the same advantages in smaller burns and there is no consensus on the timing of skin grafting in this group. The aim was to investigate the effect of timing and other factors for skin graft take rate among minor burns. MethodsThis retrospective study included patients with thermal injury, a burn size smaller than 11 % total body surface area (TBSA), and who were treated with a skin graft operation. Take rate at the second dressing change after operation was used as main outcome, a cut-off of 95% take rate was for the multivariable logistic regression. ResultsA total of 195 patients were included, median (IQR) age was 42 (9–68) years, 65 % were male, and median (IQR) area of deep burns was 2 (1–4) % of the body surface area (BSA). Multivariable regression showed that smaller area of deep burns and scalds (compared with flame and contact burns) were associated with a take rate of ≥ 95 %. Age, timing of the skin graft transplantation, and plasma C-reactive protein showed no independent effect on take rate. The regression model was significant but weak (ROC AUC 0.71, 95 % CI 0.62–0.79). ConclusionOur results suggest that the extent and depth of the burn are the most important factors for skin graft take rate among minor burns, while timing of the transplantation is not associated with take rate for the skin graft. The advantageous effect of scalds may be interpreted to mean that scalds in general are more superficial than flame and contact burns, a difference that may not be detected by the use of a Lund and Browder chart. The conclusion is, however, tempered by the retrospective study design and the relatively low discriminatory power in our study.

Association between community distress and return to work after burn injury

IntroductionCommunity-level disadvantage is associated with reduced quality of life after burn injury. We evaluated the association between community-level disadvantage and return to work after burn injury. MethodsA multicenter burn injury database was queried from 1998–2021. Participants 18–65 years old with documented employment status and ZIP codes were included. Exposures were community distress (Distressed Communities Index, DCI), patient demographics, and burn characteristics. The primary outcome was odds of employment 6 months after burn injury using stepwise logistic regression models, first with patient-level variables, then DCI. An interaction term was included to evaluate the modification of DCI and post-injury employment by race. Results1960 participants were included, with a median age of 39.2 years (IQR 29.2, 49.3); 81 % were White, 75 % male, and 74 % were working at the time of injury. Participants unemployed 6 months post-injury were more often older, female, non-White, and unemployed at injury, with larger burn sizes and longer hospitalizations. 59 % of participants unemployed at 6 months were employed at the time of injury. Residence in the highest distress ZIP codes was associated with 2.21 (95 % CI 1.39–3.52) odds of 6 month unemployment. Older age, larger burn size, more operations, Black race, and pre-injury unemployment were associated with the greatest odds of unemployment. The interaction between race and DCI was not statistically significant. ConclusionPatients from the highest distress communities have twice the odds of unemployment 6 months after injury. This association did not vary by race. Screening for DCI by ZIP code may be a useful tool to focus vocational rehabilitation resources.

The Impact of Body Image on Physical Function and Return to Work After Burn: A Burn Model System Study

Abstract Burn injury can have a lasting impact on quality of life beyond the initial injury. The aim of this study was to examine the recovery process through analyzing the relationship between body image, physical function, and return to work. This study uses data from the Burn Model System National Longitudinal Database and includes 1001 participants injured between 2015 and 2023 who were measured using Patient-Reported Outcomes Measurement Information System-29 Physical Function, Employment Status, and the Body Image subscale. Associations were explored using multivariate linear and logistic regression analyses. Physical function was positively associated with body image and negatively associated with burn size, age, and amputation. Employment was positively correlated with body image and employment at injury, while negatively correlated with age. Other variables, including burn etiology, burn center site, race, and ethnicity, were significant at different time points. By understanding how these factors change and are associated with outcomes across recovery, the healthcare team can make more tailored efforts to improve the psychosocial and physical well-being of burn survivors.

Trace Element Supplementation in Burn Patients: Exploring the Relationship Between Burn Size and Mineral Needs.

Trace element deficiency is an adverse nutritional outcome that can occur with burn injuries, and can interfere with a patient's recovery. The aim of this study was to review the efficacy of our predominately enteral trace element supplementation strategy and determine the burn size at which patients are at risk for trace element deficiency. We reviewed 53 burn patients admitted to our burn center from August 1, 2019 to May 31, 2022 who had their trace element levels and C-reactive protein monitored in two-week increments. Receiver operating characteristic analysis indicated a 22.1% BSAB cutoff for zinc supplementation to prevent deficiency with 91.7% sensitivity and 92.6% specificity, and a 27.5% BSAB cutoff with 88.9% sensitivity and 81% specificity for copper. No patient in our cohort developed selenium deficiency, regardless of burn size. Patients with greater than 30% body surface area burned developed deficiencies in both zinc and copper within the first two weeks of hospitalization. Our results provide guidance for trace element replacement based on burn size.

FP7.20 - Peri-orbital burns: A 5-Year Review of the Epidemiological Characteristics and Outcomes at a Regional Burns Centre in the UK 2019 – 2023

Abstract Background Burn injuries are a major cause of global morbidity. Despite being infrequent, peri-orbital and ocular burns can have significant implications on a patient’s vision and overall quality of life. In Northern Ireland, the current epidemiological landscape of peri-orbital burns is not clear. This study aimed at assessing the incidence of peri-orbital and ocular burns and the management outcomes of patients admitted at the regional burns unit in Northern Ireland 2019-2023. Methods Patients admitted to the regional burns unit in Northern Ireland between January 2019 and September 2023 with periorbital burns were identified from the burns unit electronic records, the burns unit database and hospital image database. Results Over 5 years, 100 patients with facial burns were treated, including 60 patients with eyelid burns. 71% were males and 29% were females with a mean age of 47 years. The mean burn size was 14% total body surface area. The burn depth varied; 55% superficial partial thickness, 22% mixed, 17% full thickness and 6% deep dermal. Majority of burns were flame burns 64%. In total, 7 patients sustained corneal burns, one patient responded to steroids, one underwent amniotic membrane grafting, one lost complete vision in both eyes, one had physical debridement and topical antimicrobials and three patients required periorbital reconstruction to maintain eye closure. Conclusion 60% of Facial burns were associated with eyelid burns, the majority of which were caused by flame burns and were managed conservatively with wound cleaning, physical debridement, and application of topical antimicrobials. Despite being rare, complete loss of vision was associated with mortality among our patients.

Higher energy delivery is associated with improved long-term survival among adults with major burn injury: A multicenter, multinational, observational study.

Numerous feeding strategies have been used to mitigate the catabolism of major burn injury. Whether higher energy and/or protein delivery results in better long-term outcomes is unknown. We performed a secondary analysis of data from adults with major burn injuries enrolled in the Randomized Trial of Enteral Glutamine to Minimize the Effects of Burn Injury at 54 burn centers in 18 countries. The sample was restricted to those who were mechanically ventilated within 72 hours of injury and for ≥7 days. Our key exposure was adequacy of energy, and protein ([Deliveredi/Prescribedi] × 100) was categorized into three groups each: low, 0% to 50%; moderate, ≥50% to 79%; and high, ≥80%. We also analyzed adequacy using restricted cubic splines. Primary and secondary outcomes included 6-month mortality and functional outcomes (i.e., 36-Item Short-Form Health Survey, Katz Index of Independence in Activities of Daily Living, Lawton Activities of Daily Living scores), respectively. Regression models were adjusted for age, body mass index, Charlson Comorbidity Index, baseline Acute Physiology and Chronic Health Evaluation II and modified Sequential Organ Failure Assessment scores, burn size, energy/protein adequacy, and study site. A total of 493 participants met the cohort restriction criteria; 336 participants were alive at 6 months. 36-Item Short-Form Health Survey, Katz Index of Independence in Activities of Daily Living, and Lawton Instrumental Activities of Daily Living Scale were completed by 218, 216, and 215 participants, respectively. The mean ± SD age was 48 ± 17 years, and 74% were male. The mean ± SD burn size was 41% ± 18% total body surface area. Participants who received 25% of recommended calories had nearly four times the hazard of death during the 6-month follow-up period than participants who received 100% of prescribed calories (adjusted hazard ratio, 3.89; 95% confidence interval, 1.35-11.20) (p = 0.02). There was no significant association between protein and 6-month mortality or energy/protein delivery and 6-month functional outcomes. There was a positive association between higher doses of energy and 6-month survival. This relationship conflicts somewhat with several energy studies among critically ill and non-burn-injured patients. The lack of consistent evidence on optimal nutrition for critically injured patients, a fundamental component of burn care, suggests potential for a randomized trial of lower versus higher energy to improve long-term outcomes after burn injury.

Burn Injury in Obesity: Examination of the Burn Care Quality Platform’s (BCQP) Available Data on Obese Patients to Determine Burn Related Outcomes

IntroductionLiterature examining the impact of obesity in burn injury remains mixed. Previous examination of the National Burn Repository, now the BCQP, in obesity-related burn research is limited. The aim of this work was to provide an assessment of the BCQP dataset to examine the effect of obesity on burn-related outcomes. Materials and MethodsA retrospective review of the BCQP dataset from 2015-2018 was conducted. The primary outcome measure was mortality. Secondary outcomes included overall length of stay (LOS), ICU LOS, and total hospital costs. Patients were grouped as obese or non-obese and further stratified by total body surface area burn (TBSA) size for comparison purposes. Multiple logistic regression (MLG) was used to compare the effect of several independent variables on mortality, ICU LOS >7days, hospital LOS >10 days and total hospital costs >$200,000. ResultsOf 41,031 patients in the analysis, 3,845 (9.37%) were obese. Obese patients had a higher mean TBSA (p=0.01), longer overall LOS (p<0.001), ICU LOS (p<0.001) and total hospital costs (p<0.001). MLG found obesity to an independent predictor of ICU LOS >7 days, hospital LOS >10 days and total hospital costs >$200,000. Obesity was not an independent predictor of mortality in burn patients even stratified by burn size. ConclusionsThe presence of obesity in this dataset was not found to be a predictor of mortality for any burn size, but was a predictor of overall LOS, ICU LOS, and total hospital costs. Including obesity-related parameters in databases may improve analysis in obesity-related burn research.

Pediatric Patients with Postburn Amputations Report Worse Long-term Physical Function but Not Self-Appearance: A Burn Model System Study.

Some severe burn injuries may warrant amputation; however, the physical and functional adjustments resulting from postburn amputation can have long-term consequences. This study investigates longitudinal functional and psychosocial outcomes among pediatric burn amputees. Pediatric participants enrolled in the Burn Model System national longitudinal, multicenter database between 2015 and 2023 with postburn amputations were included. Participants with amputations were matched using nearest-neighbor matching to those without amputations based on burn location, age, and % total burn surface area burn size. Primary outcomes were the Patient-Reported Outcomes Measurement Information System Pediatric-25 Profile v2.0 Physical Function and the Children Burn Outcomes Questionnaire: appearance subscore, both measured at 6-, 12-, and 24 months postburn. In this study, 17 participants had amputations, and 17 did not (matched participants). Pairwise analyses at each timepoint found those with amputations reported significantly lower physical function scores at 24 months postburn (54.9 ± 11.6 vs 66 ± 5, P = .013). No significant differences were found in appearance scores. This study suggests that pediatric burn amputees may potentially face greater physical impairment long-term, highlighting an important area of research that deserves further attention.

Effect of a transitional tele-rehabilitation programme on quality of life of adult burn survivors: A randomised controlled trial

Objective To examine the effects of the transitional tele-rehabilitation programme on quality of life of adult burn survivors. Design A prospective, single centre, randomised controlled trial and reported according to the Consolidated Standards of Reporting Trials (CONSORT) guidelines. Participants Adult burn survivors aged ≥18 years with burn size ≥10% total body surface area irrespective of the depth was considered eligible to participate. Intervention The intervention was in two phases: pre-discharge and active follow-up phase (which occurred via WeChat). In both phases, comprehensive assessment and intervention guided by the Omaha System and evidenced-based protocols guided the care delivery over an 8-week period. Main measures The outcome of interest was quality of life. Two outcome measures were used to assess the outcome of interest: Burn Specific Health Scale-Brief (BSHS-B) and the EQ-5D-5L tools. The outcome was assessed at three time points: T0 (baseline), T1 (immediate post-intervention) and T2 (4 weeks from T1). Results In total, 60 adult burn survivors were randomly allocated to undergo the new programme. The transitional tele-rehabilitation programme elicited statistically significant improvement in simple abilities, affect, interpersonal relationship (T2) and overall quality life (T1 and T2) measured on the BSHS-B. Conclusion Ongoing rehabilitative care is essential to support the recovery process of burn survivors considering that some quality-of-life subscales may improve faster than others. The study findings highlight the potential of employing a social media platform to improve post-burn quality of life outcomes. Trial registration ClinicalTrials.govNCT04517721.

Swallowing impairment in older persons following burn injury: Validation of incidence and predictive factors for dysphagia

BackgroundEarly retrospective data identify that dysphagia is common in older persons with burn injury, suggesting a rate of 47 %, and that it is associated with medical, burn, and nutritional outcomes. AimsTo prospectively (1) explore the incidence, (2) describe associations, and (3) evaluate risk factors for dysphagia in patients ≥ 75 years old hospitalised with burn injury. MethodsAll patients > 75 years old admitted to Concord-Repatriation-General-Hospital with burn injury over 4 years (2019–2023) were assessed for dysphagia on presentation and were continually monitored throughout their admission. Burn injury, demographic, and nutritional data were prospectively captured and analysed for association with dysphagia. ResultsSixty-two patients (33 male) aged 75–95 years (median=83 years) were recruited. Dysphagia was identified in 50 %. Dysphagia was associated with burn size (p = 0.002), pre-existing cognitive impairment (p = 0.000), hospital length of stay (p = 0.001), in-hospital complications (p = 0.000), feeding dependence (p = 0.002), nutritional status (p = 0.013) and enteral feeding duration (p = 0.030). Cognitive impairment was the most sensitive predictor for dysphagia at 100 % (specificity=29 %, NPV=100 %, PPV=59 %). Development of secondary comorbidities was less sensitive at 52 % (NPV 65 %), but was associated with high specificity (90 %) and PPV (84 %). ConclusionsOne in every two patients ≥ 75 years admitted with burn injury will demonstrate dysphagia during their hospital admission. Those with pre-existing cognitive impairment are most at risk.

Advanced fluid management strategies in burn patients undergoing general surgery: a comprehensive review

Fluid management in burn patients undergoing general surgery poses unique challenges due to the complex pathophysiological changes associated with burn injuries. Effective resuscitation and perioperative fluid therapy are critical in optimizing outcomes and minimizing complications in this vulnerable patient population. This review explores the latest evidence-based approaches to fluid management in burn patients, emphasizing the importance of individualized strategies that consider burn size, depth, patient age, comorbidities, and surgical factors. We examine the role of advanced hemodynamic monitoring, crystalloid versus colloid solutions, and the integration of goal-directed therapy protocols. Additionally, we discuss the implications of burn-related complications such as systemic inflammatory response syndrome (SIRS), sepsis, and multi-organ dysfunction on fluid management strategies. By synthesizing current research and clinical guidelines, this review aims to provide a comprehensive framework for clinicians to enhance perioperative care in burn patients undergoing general surgery.

FireSync EMS: A Novel Mobile Application for Burn Surface Area Calculation.

The percent total body surface area burned is a critical determinant of the required level of care, initial management, and prognosis in burn patients. The current gold standard for estimating this measurement, the Lund-Browder chart, requires familiarity with its construction and may not be practical for use by first responders in the field. In this study, we present a novel burn surface area calculator mobile application developed for first responders and validate its accuracy. Infant, pediatric, and adult manikins were fabricated with eight simulated burns of varying sizes and distributions. 42 pre-clinical medical students and firefighters were tasked with estimating the total body surface area of each burn using both the FireSync-EMS app and Lund-Browder chart. Univariate analysis and mixed-effects linear regression modeling were performed to compare the accuracy of both methods in relation to user experience, manikin size, and burn size. FireSync-EMS significantly reduced overestimation bias (0.11%, SD 2.33 versus 0.91%, SD 4.12, p = 0.002), particularly for burns on child-size manikins (p < 0.001) and burns involving <10% (p = 0.005) and >20% (p = 0.030) total body surface area. Multivariable modeling revealed that the Lund-Browder chart was an independent determinant of the magnitude of estimation error, with a 1.19 times multiplicative effect relative to FireSyncEMS (p < 0.001). Participants overwhelmingly found FireSync-EMS easier, more intuitive, faster, and preferable (p < 0.001 for all). FireSync-EMS may be an easier, faster, and more accurate alternative to the Lund-Browder chart for estimation of the total body surface area burned.

Burn vs. Referral Physicians' TBSA Estimation Errors: A Cross-Sectional Study at the National Burn Center

BackgroundThe percentage of the total body surface area (TBSA) is a simplified way to address the magnitude and severity of a thermal injury. The burn care providers recognize the relationship between burn size, prognosis, and number of required interventions. This study aims to identify the prevalence and magnitude of TBSA estimation inconsistencies between referring hospitals and the National Burn Center in Mexico and introduce new telemedicine and mobile applications for effectively estimating burn areas for non-burn-trained personnel. MethodsWe included patients with any thermal injury at the National Rehabilitation Institute in Mexico City referred from any other hospital in the country. Data was collected from the referral email and our medical records, and the burn estimation error was calculated using the following formula: (TBSA referral Hospital – TBSA Burn Center) / TBSA Burn Center multiplied by 100. ResultsSeventy-eight patients were transferred to the institute; the mean age was 27 years, 55 were male. The mean %TBSA from the referring hospital was 36 %, and in our Burn Center was 28 %, with a mean difference of 8.8 %. There were 59 cases with overestimated %TBSA, and ten were underestimated; the rest were similar in percentage. ConclusionsOur study highlights substantial discrepancies between the estimated %TBSA by referring hospitals and the actual %TBSA, consistently tending towards overestimation.

Too hot to handle − Microwaved drinkware: An emerging cause of contact burn injuries?

Purpose of the studyTo investigate the local and national incidence of contact burns secondary to microwave-heated drinkware and specifically those with a metallic coating. MethodsThis retrospective analysis from November 2018 to December 2022 includes UK-wide data on burn mechanism, demographics, TBSA (total body surface area), depth and additionally, local data on injury details, management, complications, healing duration, return-to-work time, and follow-up duration within our service. ResultsNational: In the UK, 87 patients sustained burns related to microwave heating of drinkware. Median (IQR) burn size was 0.21% (+/−0.15) TBSA. Most burn injuries were superficial dermal (SD) (88.7%). All cases were treated conservatively.Regional: Contact burns from microwave-heated metallic coated drinkware were identified in 28 patients. The median (IQR) TBSA was 0.12% (+/−0). Most injuries were assessed as SD (90%, 45/50), however, 4/5 (80%) of the deeper burns were caused by metallic-coated drinkware. The median (IQR) follow-up was 6.04 days (+/−4.5). Median (IQR) healing time was 14.17 (+/−0) days and mean time to return to work was 7.57 (+/−3.5) days. ConclusionsMicrowave-heated drinkware burns, while constituting a small portion of referrals to UK burns services, may have a larger true population incidence. Due to their size, these injuries are probably treated locally without referral to a burns service. Regional data analysis highlighted that metallic coated drinkware related injuries were associated with longer healing times.

Severity of Inhalation Injury and Risk of Nosocomial Pneumonia: A Retrospective Cohort Study

BackgroundThe impact of inhalation injury on risk of nosocomial pneumonia, an important complication in burn patients, is not well established. Research QuestionIs more severe inhalation injury associated with increased risk of nosocomial pneumonia? Study Design and MethodsWe performed a retrospective cohort study of patients with suspected inhalation injury admitted to a regional burn center from 2011 to 2022 who underwent diagnostic bronchoscopy within 48 hours of admission. We estimated the association of high-grade inhalation injury (abbreviated injury score [AIS] 3-4) versus low-grade inhalation injury (AIS 1-2) with nosocomial pneumonia (NP) adjusted for age, burn size, and comorbid obstructive lung disease. Death and hospital discharge were considered competing risks. ResultsOf the 245 patients analyzed, 51 (21%) had high-grade injury, 180 (73%) had low-grade injury, and 14 (6%) had no inhalation injury. Among the 236 patients hospitalized for >48 hours, NP occurred in 24/50 (48%) patients in the high-grade group, 54/172 (31%) in the low-grade group, and 2/14 (14%) in the no inhalation injury group. High-grade (vs low-grade) inhalation injury was associated with higher hazard of NP in both the proportional cause-specific hazard model (CSHR 2.04; 95% CI, 1.26-3.30; p=0.004) and Fine-Gray subdistribution hazards model (SHR for NP, 2.24; 95% CI, 1.38-3.64; p=0.001). InterpretationAmong patients with inhalation injury, more severe injury was associated with higher hazard of NP in competing risk analysis. Additional research is needed to investigate mechanisms that may explain the relationship between inhalation injury and NP and to identify more effective prevention strategies.

Outcome comparison of the most commonly employed wound coverage techniques in patients with massive burns ≥50% TBSA – A systematic review and meta-analysis

IntroductionEarly wound coverage is one of the most essential factors influencing the survival of extensively burned patients, especially those with a total body surface area (TBSA) burned greater than 50 %. In patients with limited donor sites available for autografting, techniques such as the Meek micrograft procedure or cultured epidermal allografts (CEA) have proven to be viable alternatives. In this systematic review and meta-analysis, we analyzed the outcomes of different wound coverage techniques in patients with massive burn injuries ≥ 50 % TBSA in the past 17 years. MethodsThe EMBASE, PUBMED, Google Scholar and MEDLINE databases were searched from inception to December 2022 for studies investigating major burn reconstruction (>50 % TBSA) with the use of one of: a) autografts, b) allografts, c) cell-based therapies, and d) Meek micrografting. The review was conducted in accordance with the PRISMA guidelines. The outcomes evaluated were mortality, length of hospital stay, graft take and number of operations performed. ResultsFollowing a two-stage review process, 30 studies with 1369 patients were identified for analysis. Methods of coverage comprised the original autografting, and the newer Meek micrografting, CEA autografting, and allografting. Pooled mean age of the entire cohort was 32.5 years ( ± SE 3.6) with mean burn size of 66.1 % ( ± 2.5). After pooling the data, advantages in terms of mortality rate, length of stay, graft take and number of required surgeries were seen for the Meek and CEA groups. Mortality was highest in patients treated with autografts (50 %) and lowest with cell-based therapy (11 %). Length of stay was longest with cell-based therapy (91 ± 16 days) and shortest with Meek micrografting (50 ± 24 days). Graft take was highest with autografts (96 ± 2 %) and lowest with cell-based therapy (72 ± 9 %). Average number of operations was highest with cell-based therapy (9 ± 4) and lowest with Meek micrografting (4 ± 2). ConclusionsComparison of the four techniques highlighted differences in terms of all outcomes assessed, and each technique was associated with different advantages. Interestingly autografting, the option with the highest graft take rate, was also associated with the highest mortality. This study not only serves to provide the first comparison of the most commonly used techniques in major burn reconstruction, but also highlights the need for prospective studies that directly compare the efficacy of the different techniques to ultimately establish whether a true superior option exists.

Fractional CO2 Laser for Burn Scars: A Comparison of Patient-Reported Outcomes Between Those With and Without Laser Treatment.

Burn reconstruction outcomes are an area of growing investigation. Although there is evidence of measured physical improvements in scar characteristics after laser treatment, there is little information on patient-reported outcomes. The purpose of this study is to compare patient-reported outcomes between burn survivors with and without laser treatment. The study included participants in the Burn Model System National Database at a single center; participants that received outpatient laser treatment for burn scars were compared to a matched group of burn survivors that did not receive laser. The following outcomes were examined: Satisfaction With Life Scale, Mental and Physical Component Summary of the Veterans Rand Survey, and the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Scale. Regression analyses examined the associations between laser treatment and each outcome at 12 and 24 months. The study population included 287 adult burn survivors (65 laser group and 222 control group). The significant differences found between the 2 groups included: burn size (laser: 14.9, 13.5 SD, control: 8.9, 11.1 SD; P < .001), insurance type (P = .036), inhalation injury (laser: 17.2%, control: 2.7%; P < .001), and ventilator requirement (laser: 27.7%, control: 13.5%; P = .013). Laser treatment was not associated with any of the outcomes at both follow-up time points. Further research is needed to develop patient-reported outcome measures that are more sensitive to the clinical changes experienced by burn survivors receiving laser treatment.

Comparing artificial intelligence guided image assessment to current methods of burn assessment.

Appropriate identification of burn depth and size is paramount. Despite the development of burn depth assessment aids [e.g., laser doppler imaging (LDI)], clinical assessment, which assesses partial thickness burn depth with 67% accuracy, currently remains the most consistent standard of practice. We sought to develop an image-based artificial intelligence system that predicts burn severity and wound margins for use as a triaging tool in thermal injury management. Modified EfficientNet architecture trained by 1684 mobile-device-captured images of different burn depths were previously utilized to create a convoluted neural network (CNN). The CNN was modified to a novel Boundary-Attention Mapping (BAM) algorithm using elements of saliency mapping, which was utilized to recognize the boundaries of burns. For validation, 144 patient charts that included clinical assessment, burn location, total body surface area, and LDI assessment were retrieved for a retrospective study. The clinical images underwent CNN-BAM assessment and were directly compared with the LDI assessment. CNN using a four-level burn severity classification achieved an accuracy of 85% (micro/macro-averaged ROC scores). The CNN-BAM system can successfully highlight burns from surrounding tissue with high confidence. CNN-BAM burn area segmentations attained a 91.6% accuracy, 78.2% sensitivity, and 93.4% specificity, when compared to LDI methodology. Results comparing the CNN-BAM outputs to clinical and LDI assessments have shown a high degree of correlation between the CNN-BAM burn severity predictions to those extrapolated from LDI healing potential (66% agreement). CNN-BAM algorithm gives equivalent burn-depth detection accuracy as LDI with a more economical and accessible application when embedded in a mobile device.
