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 Clinically used TBSA equations are often outdated and inaccurate with error up to 20%, resulting in misinformed treatment and subsequent sequelae including prolonged hospital length of stay and increased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.

Abstract Background Chronic pain, unrelated to the burn itself, can manifest as a long-term complication in patients sustaining burn injuries. The purpose of this study was to determine the prevalence of chronic neuropathic pain (CNP) and compare burn characteristics between patients who developed CNP and patients without CNP who were treated at a burn center. Methods A single-center, retrospective analysis of 1880 patients admitted to the adult burn center was performed from 1 January 2014 to 1 January 2019. Patients included were over the age of 15 years, sustained a burn injury and were admitted to the burn center. CNP was diagnosed clinically following burn injury. Patients were excluded from the definition of CNP if their pain was due to an underlying illness or medication. Comparisons between patients admitted to the burn center with no pain and patients admitted to the burn center who developed CNP were performed. Results One hundred and thirteen of the 1880 burn patients developed CNP as a direct result of burn injury over 5 years with a prevalence of 6.01%. Patients who developed CNP were a significantly older median age (54 years vs. 46 years, p = 0.002), abused alcohol (29% vs. 8%, p < 0.001), abused substances (31% vs. 9%, p < 0.001), were current daily smokers (73% vs. 33%, p < 0.001), suffered more full-thickness burns (58% vs. 43%, p < 0.001), greater median percent of total body surface area (%TBSA) burns (6 vs. 3.5, p < 0.001), were more often intubated on mechanical ventilation (33% vs. 14%, p < 0.001), greater median number of surgeries (2 vs. 0, p < 0.001) and longer median hospital length of stay (LOS) (10 days vs. 3 days, p < 0.001), compared to those who did not develop CNP, respectively. Median patient follow-up was 27 months. Conclusions The prevalence of CNP over 5 years was 6.01% in the burn center. Older ages, alcohol abuse, substance abuse, current daily smoking, greater percent of total body surface area (%TBSA) burns, third degree burns, being intubated on mechanical ventilation, having more surgeries and longer hospital LOS were associated with developing CNP following burn injury, compared to patients who did not develop CNP following burn injury.

Abstract Introduction Estimates on frequency and outcomes of burn or inhalation injury in the United States are limited since reported databases are confined to specific phases of care, included facilities, length of follow-up, facility/provider/patient identification and/or lack of longitudinal tracking. A population-based database addresses these issues. Methods We queried a statewide mandated-reporting database for the years from 2000 through 2015 at the time of injury using a set of ICD9-CM codes for second degree or deeper burns, inhalation injury, and chemical and electrical burns. Burn total body surface area percentage by anatomical region was assigned as appropriate using modified and age-stratified Lund and Browder charts. Records for each patient were extracted out to one year pre- and post-injury, as available. Provider and facility burn volume and survival was stratified into quartiles. We applied the Committee on Trauma/American Burn Association referral criteria to the index presentation. Kaplan-Meier curves were generated to 1-year post injury for testing combinations of burn percent total body surface area of 20% and inhalation injury for age ranges < 15, 15 - 60, and >60 years. Regression models were developed to model the probabilities of in-patient, 90-day, and 365-day mortality and readmission. Results 56,712 patients were included. Overall, 22% of patients meeting referral criteria were never seen at a burn center within 1-year post-injury. The greatest positive predictors of in-patient mortality were facility case volume and burn percent total body surface area. The greatest negative predictors were high provider burn case volume (for highest quartile, adjusted odds ratio 0.08, 95% confidence intervals 0.06 – 0.12). The highest risk of unscheduled 30-day readmission was associated with index presentation to a non-burn care facility (p < 0.001). For all groups, the first 100 days had the greatest mortality rate, the most severe being among patients of age greater than 60 with >20% burn percent total body surface area and inhalation injury, with a 40% survival rate. Conclusions This study is the first to be able to simultaneously evaluate in-patient, post-discharge, and facility-based parameters for outcomes. A significant number of patients are not accounted with current databases. Applicability of Research to Practice A population-based approach with longitudinal tracking allows for greater realization of the outcomes of all patients following burn injury. Existing association-supported or government databases fail to account for a significant portion of burn victims, motivating further evaluation of burn care efforts.

Recovery from an Eighty-Percent Total Body Surface Area Burn Injury Sustained at WorkThis article presents a case of severe burn injury at work involving 80 % of body surface area and patient treatment and rehabilitation, which resulted in preserved working ability. The worker was injured by hot water and steam. After initial treatment in the intensive care unit, he underwent comprehensive clinical and outpatient rehabilitation that took 92 weeks, after which he returned to work. His working disability was 100 % after the initial treatment in the intensive care unit, but rehabilitation improved it to 50 %. It should always be kept in mind that even patients with serious or life-threatening injuries can be reintegrated into the workforce if patients, physicians, occupational physicians, and employers all work together.

Abstract Introduction Outpatient burn surgery is increasingly utilized for delivery of acute burn care. Reports of its safety and efficacy are limited. The purpose of our study was to evaluate the safety and cost reduction associated with outpatient burn surgery and to describe our centre’s experience. Methods This was a single centre, retrospective cohort study of consecutive patients who underwent outpatient acute burn surgery requiring split thickness skin graft or dermal regenerative template from January 2010 - December 2018. Patients with insufficient follow up to evaluate operative site healing were excluded. Patient demographics, comorbidities, burn etiologies, operative data and postoperative care were reviewed. The primary outcome is complication involving major graft loss requiring reoperation. Results 165 patients and 173 procedures met the inclusion criteria. The average age was 44 years and 60.6% (100/165) were male. The number of annual outpatient procedures increased 48% from 23 to 34 cases over the 9-year period. The mean grafted total body surface area was 1.0 ± 0.9%. Rate of major graft loss requiring reoperation was 5.2% (9/172). Greater than 95% graft take was achieved in 80.9% of patients. Age, sex, co-morbidities, total body surface area, and procedure types were not significantly associated with postoperative complication rate. Outpatient burn surgery model was estimated to save CA$7,875 per patient from inpatient costs. This extrapolates to a total of over CA$1.36 million in savings over the 9-year study period. Conclusions Acute burn care at our centre is increasingly being delivered through an outpatient day surgery model. Our demonstration of its safety and considerable cost savings is compelling for further utilization. Our experience found the adoption of improved dressing care, appropriate patient selection, increased patient education, adequate pain control, and regimented outpatient multidisciplinary care to be fundamental for effective outpatient surgical burn care.

Abstract Introduction Studies on length of stay (LOS) per total body surface area (TBSA) burn in pediatric patients have been performed at single institutions and based on ranges of TBSA burn. A LOS to TBSA burn ratio of 1:1 has also been widely accepted but not confirmed over time across numerous institutions. The objective of this study was to use multi-institutional pediatric burn data to describe benchmarks associated with LOS per TBSA burn. Methods Data from the Pediatric Injury Quality Improvement Collaborative (PIQIC) were obtained for 1004 patients (n=1004) treated at five pediatric burn centers from July 2018-March 2020. LOS/TBSA burn ratios were calculated for each site. LOS/TBSA burn by institution and mechanism were analyzed. Generalized linear regression models were used to model the effect of hospital and burn mechanism on the LOS/TBSA ratio. Results Among the 1004 injuries, the most common burn mechanism was by scald (64%), followed by contact (16%) and flame (13%). The average LOS/TBSA burn ratio across all cases was 1.3 days (SD 2.2). Flame burns had a higher LOS/TBSA burn ratio than scald burns with a mean LOS/TBSA burn of 1.63 compared to 0.84. In adjusted models, scald burns, and chemical burns had the lowest LOS/TBSA burn ratio and electrical and friction burns had the highest LOS/TBSA burn ratio. The LOS/TBSA burn ratio was comparable across hospitals after adjustment for mechanism, with just Hospital 4 having a lower average LOS/TBSA burn of 0.49 days. Conclusions These data establish a multi-institutional ratio for the overall performance in LOS for pediatric burn patients. A LOS per TBSA ratio of about 1 was observed across PIQIC centers, except for a lower ratio at one center. Additionally, it provides evidence on the variance in LOS per TBSA burn relative to the sustained burn mechanism. Further collaborative data analysis will allow us to recognize specific patterns and outcomes in pediatric burn care, which is essential for the implementation of quality improvement standards.

Rate of major graft loss requiring reoperation was 5.2% (9/172) and the most common site was the lower extremity (8/9, 88.9%). Age, sex, co-morbidities, total body surface area, and procedure types were not significantly associated with postoperative complication rates. The outpatient burn surgery model was estimated to save CA$8,170 per patient from inpatient costs. Conclusion Demonstration of the safety and cost savings associated with outpatient acute burn surgery is compelling for further utilization. Our experience found the adoption of improved dressing care, appropriate patient selection, increased patient education, adequate pain control, and regimented outpatient multidisciplinary care to be fundamental for effective outpatient surgical burn care.

Abstract Burn injury represents a substantial burden of disease in resource-limited settings. Kenya has no formal trauma system and referral practices for burn injuries are not well understood. The purpose of this study was to determine the factors associated with burn injury referrals in rural Kenya. A retrospective chart review was conducted for patients with burn injury from January 1, 2014 to December 31, 2017 at a 300-bed faith-based, teaching hospital in southwest Kenya. Bivariate analysis compared referred and non-referred patients. Multivariable logistic regression was used to assess the association between burn severity and odds of referral adjusting for age, sex, insurance, time from injury to arrival, and estimated travel time from home to hospital. The study included 171 patients with burn injury; 11 patients were excluded due to missing referral data. Of the 160 patients, 31.9% (n = 51) were referred. Referral patients had higher average total body surface area burn (23.1 ± 2.4% vs 11.1 ± 1.2%, P < .001), were more likely to have full-thickness burns (41.3% vs 25.5%, P = .05), and less likely to present to the referral hospital within 24 hours after injury (47.8% vs 73.0%, P = .005). Referral patients had longer travel time to hospital (90+ min: 52.9% vs 22.0%, P < .001). Odds of referral increased 1.62 times (95% confidence interval: 1.19–2.22) for every 10% increase in total body surface area burn. Without a coordinated trauma system, referrals represent a substantial portion of burn injury patients at a hospital in rural Kenya. Referred patients present with more severe burns and experience delays to presentation.
