RESUMO

Despite differing etiologies, acute thermal burn injuries and full-thickness (FT) skin defects are associated with similar therapeutic challenges. When not amenable to primary or secondary closure, the conventional standard of care (SoC) treatment for these wound types is split-thickness skin grafting (STSG). This invasive procedure requires adequate availability of donor skin and is associated with donor site morbidity, high healthcare resource use (HCRU), and costs related to prolonged hospitalization. As such, treatment options that can facilitate effective healing and donor skin sparing have been highly anticipated. The RECELL® Autologous Cell Harvesting Device facilitates preparation of an autologous skin cell suspension (ASCS) for the treatment of acute thermal burns and FT skin defects. In initial clinical trials, the approach showed superior donor skin-sparing benefits and comparable wound healing to SoC STSG among patients with acute thermal burn injuries. These findings led to approval of RECELL for this indication by the US Food and Drug Administration (FDA) in 2018. Subsequent clinical evaluation in non-thermal FT skin wounds showed that RECELL, when used in combination with widely meshed STSG, provides donor skin-sparing advantages and comparable healing outcomes compared with SoC STSG. As a result, the device received FDA approval in June of 2023 for treatment of FT skin defects caused by traumatic avulsion or surgical excision or resection. Given that health economic advantages have been demonstrated for RECELL ± STSG versus STSG alone when used for burn therapy, it is prudent to examine similarities in the burn and FT skin defect treatment pathways to forecast the potential health economic advantages for RECELL when used in FT skin defects. This article discusses the parallels between the two indications, the clinical outcomes reported for RECELL, and the HCRU and cost benefits that may be anticipated with use of the device for non-thermal FT skin defects.

RESUMO

Stevens-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) exist on a spectrum of autoimmune conditions which cause epidermal detachment and keratinocyte necrosis. Due to the rare incidence of these conditions, a dramatic heterogeneity in treatment algorithms exists. To better appreciate pharmacologic immunosuppressive therapies' impact on survival, the authors queried a multi-institutional data network. Data for this study was extracted from TriNetX Research Network, a platform that contains ICD-9/ICD-10 coding data from a consortium of international healthcare organizations. Seventy-one institutions were queried to identify adult patients diagnosed with SJS, TEN or SJS-TEN Overlap. Cohorts were created based on the therapy received: systemic steroids (SS), diphenhydramine (DH), cyclosporine (CS), intravenous immunoglobulin (IVIG), tumor necrosis factor alpha inhibitors (TNFαi), or a combination of treatments. Cohorts were then propensity matched with patients who received supportive care. Patients who only received one of the above treatments showed no significant reduction in 90-day mortality. Patients who received CS or IVIG as part of their multitherapy showed a significantly increased risk of death when compared to supportive care (CS: RR = 1.583, 95% CI [1.119, 2.240]; IVIG: RR = 2.132, 95% CI [1.485, 3.059]). Despite their frequent utilization, this study's analysis suggests that none of these therapies confer significant 90-day mortality survival over supportive care alone. These results highlight the heterogeneity of therapies and emphasize the need for critical prospective appraisal of their outcomes in SJS and TEN.

RESUMO

Many reports pertaining to burns from e-cigarette battery explosions exist, as do injuries from smoking conventional cigarettes while on home-oxygen therapy. However, literature regarding burn injuries from e-cigarettes while on oxygen therapy is limited. The heating coil of the device can rise to temperatures that facilitates ignition of oxygen. The purpose of this study is to describe and characterize this novel and under-reported mechanism of injury. This study was a descriptive review of 2013-2016 National Burn Repository (NBR) data, with a query for "oxygen," "O2," "electronic cigarettes," and various permutations/abbreviations/misspellings. Demographics, injury characteristics, and outcomes were reported. Also, a Google search for lay-press articles and a PubMed/Scopus search using similar terms was conducted to find literature. Of approximately 60,000 NBR entries, 8 records of injury while smoking e-cigarettes on oxygen were found. Patients were predominantly male, 63 ± 9 years old, with 3.4% ± 4 TBSA burns, and LOS of 5.8 ± 7 days (an LOS O/E ratio of 1.5). Two patients sustained full-thickness burns (0.5% and 11% TBSA). Three were intubated, with mean of 3.33 ventilator-days. Most injuries occurred at home (88%). All patients survived. A google search revealed five lay-press articles. Only three partially relevant scientific articles were found to only mention the phenomenon, without granular data. Although uncommon, smoking e-cigarettes on supplemental oxygen can result in injury without a lithium-ion battery explosion. Limitations in the database may have resulted in underestimation of injuries. A paucity of relevant literature exists, necessitating more research. Patients who receive home-O2 should be warned about this potential danger.

RESUMO

BACKGROUND & OBJECTIVES: Cyanide poisoning can occur due to exposure to smoke in closed-space fires. With no point of care cyanide test at the scene of a fire, first responders and clinicians base decisions to treat with cyanide antidote on patient history, clinical signs, and other indirect data points that have not been proven to correspond with actual systemic levels of cyanide. The aim of this exploratory study was to determine the economic implications of treating patients with known or suspected cyanide poisoning due to smoke inhalation with hydroxocobalamin. METHODS: A decision analysis model was developed from the US hospital perspective. Healthcare resource utilization was estimated from a retrospective evaluation of clinical outcomes in hydroxocobalamin-treated patients and in historical controls without hydroxocobalamin use (Nguyen, et al. 2017). Epidemiologic parameters and costs were estimated from the published literature, and publicly-available hospital charges were identified. Outcomes reported in the analysis included expected healthcare resource utilization in the US population and per-patient costs with and without the use of hydroxocobalamin. A cost-to-charge ratio was applied so that all costs would reflect hospital costs rather than hospital charges. Deterministic sensitivity analysis was performed to identify the most influential model parameters. All costs were reported in 2017 US dollars. RESULTS: Use of hydroxocobalamin reduces healthcare resource utilization and contributes to decreased per-patient hospital costs ($15,381 with hydroxocobalamin treatment versus $22,607 with no cyanide antidote). The most substantive cost-savings resulted from decreased hospital length of stay (i.e., intensive care unit [ICU] and non-ICU). Costs attributed to mechanical ventilation also decreased with use of hydroxocobalamin. A univariate sensitivity analysis demonstrated that the most impactful variables in the cost analysis were related to hospital length of stay (ICU followed by non-ICU stay), followed by the daily cost of ICU stay. CONCLUSIONS: Use of hydroxocobalamin in patients with known or suspected cyanide poisoning from closed-space fire smoke inhalation may decrease hospital costs and contribute to more efficient healthcare resource utilization.

RESUMO

INTRODUCTION: Burn injury and reconstructive operations often result in severe pain, particularly at skin graft donor sites. Traditional local anesthetics administered intraoperatively control pain at donor sites, but the duration of action is short. Liposomal bupivacaine, a novel local anesthetic, can provide sustained-release analgesia for 72h. The primary aim of this study was to describe the efficacy of liposomal bupivacaine for postoperative donor site pain control for patients undergoing skin graft procedures. METHODS: A retrospective cohort study was performed on patients who received a donor site liposomal bupivacaine field block and was compared to a matched control. Patients rated donor site pain on post-operative day 0 and 1, and stated whether the donor or graft site was more painful. RESULTS: Fifty-eight patients were included. Twenty-nine patients received liposomal bupivacaine. Eighty-six percent of patients in the treatment group rated donor site pain as three or less on postoperative day 0 and 1, compared to 3.4% in the control (p<0.0001). Also, 76% of patients in the treatment group stated donor site pain was less than graft site pain, compared to 3.4% in the control (p<0.0001). CONCLUSION: Patients who received liposomal bupivacaine reported less postoperative donor site pain and found the donor site to be less bothersome without major complications. Liposomal bupivacaine may be a safe and promising agent for prolonging postoperative analgesia and minimizing donor site pain.

RESUMO

Herpes simplex virus (HSV) is common in the population and reactivation of latent infection often occurs in times of physiologic stress, including postburn injury. Active HSV infection complicates burn injury recovery and increases morbidity. A retrospective chart review of high-risk burn patients (≥20%TBSA and/or facial burns) who had screening HSV immunoglobulin titers drawn from 2015 to 2018 was conducted. Titer levels and morbidity-related outcomes were compared between patients who developed active infection and those who did not. Fifty-six patients had serum HSV titers measured. Twenty-nine patients (52%) developed clinical signs of HSV infection, almost all of which (97%) suffered facial burns. Titers were ordered on median hospital day 1.5 (0.00-4.0) and infection occurred on day 8.0 (2.0-16). Median HSV-1,2 IgM titers were significantly increased in patients who developed clinically active HSV infection (0.71 [0.44-1.1] vs 0.52 [0.34-0.74], P = .02). Median HSV-1 IgG (P = .65) and HSV-2 IgG titers (P = .97) were not different between groups. Patients who developed active infection had a comparable hospital length of stay (27 [9.5-40] days vs 20 [8.0-28] days, P = .17) and ICU length of stay (26 [13-49] days vs 19 [11-27] days, P = .09) to those who did not develop infection. There was no difference in mortality. Increased HSV-1 and 2 IgM screening levels were associated with an increased risk of developing active HSV infection, and offer a specific screening modality in high-risk patients. Elevated IgM titers warrant further consideration for administration of HSV prophylaxis, as earlier intervention may prevent infection onset and minimize morbidity.

RESUMO

Providing adequate analgesia during burn wound care is essential to patient-centered care. Both oral and intravenous (IV) ketamine are often used for analgesia and sedation. Ketamine may improve analgesia and decrease opioid requirements for burn wound care. Oral ketamine wafers and tablets have been used as a safe alternative internationally but are unavailable in the United States. The purpose of this study was to compare opioid usage and patient satisfaction scores in patients with and without the use of oral injectable ketamine for burn wound care, with each patient serving as their own control. Ketamine, opioid, and benzodiazepine dosages recorded during dressing changes were compared to dressing changes without ketamine use that occurred before and after ketamine-associated sessions in each patient. Fourteen patients received oral ketamine at a median (interquartile range [IQR]) dose of 2.5 (2.2-2.7) mg/kg. Ketamine use significantly decreased opioid requirements when compared to wound care sessions that did not use ketamine both before (50 [IQR: 30-75] mg vs 75 [IQR: 46-91] mg median IV morphine equivalents, P = .0097) and after (50 [IQR: 30-75] mg vs 63 [IQR: 50-96] mg median IV morphine equivalents, P = .0042) the ketamine-associated sessions. One patient experienced hallucinations, and no adverse events were observed. Hence, oral administration of injectable ketamine was associated with a decrease in opioid requirements during dressing changes. Additionally, ketamine use improved patient satisfaction (P = .0034). Preliminary data suggest this promising analgesia method is safe and effective for burn wound care.

RESUMO

Burn care and medical education have undergone dramatic changes. Trauma has over seven courses covering fundamentals, whereas burns has one. Our goal was to develop a course to meet the needs of healthcare professionals requiring more advanced burn management training. A survey was distributed to burn physicians, nurses, therapists, administrators, and survivors, to assess the perceived proficiency of those managing adult and pediatric patients. Procedure simulators were developed, and a course was designed and delivered. An after-course survey of participants captured how this course filled identified knowledge gaps. A total of 188 initial surveys were sent to individuals involved in burn care. A diverse pool of 109 individuals participated (58% response rate). Survey results by providers demonstrated the lowest self-rated proficiency scores at managing large pediatric burns and frostbite. Nonphysicians reported low proficiency in developing wound treatment algorithms, performing escharotomies, and aftercare/reintegration. Following rigorous curriculum development, the course was conducted, and after-course surveys noted students' improved understanding of managing burn injuries, ability to troubleshoot, confidence to manage patients, and their recommending the course to a peer. Providing quality care beyond the initial assessment and stabilization of a burn-injured patient requires additional skills and knowledge. Providers that are uncomfortable or challenged in providing this care may benefit from additional training. Initial data show that a course, such as this one, provides the education necessary to fill the most commonly reported gaps in knowledge and skills. Further work is being invested to develop disaster management skills, assessment components, and further determine course validity.

RESUMO

INTRO: There were over 60 firefighter line of duty deaths and roughly 30,000 injuries in the United States in 2016. Modern thermoprotective gear has reduced the risks firefighters face from both thermal and inhalation injury, but must be used properly to be effective. The purpose of this study is to examine gear use and associated injury in firefighters. METHODS: Surveys were distributed with questions about demographics, gear usage, and maintenance practices. If previously injured, firefighters described the injury, treatment, and recovery. RESULTS: Of the 50 surveys distributed, 37 were returned (72%). A majority of respondents (70%) reported wearing incomplete gear. Those who reported injury were more likely to have omitted gear (81% vs 45%). For all respondents, the items most commonly omitted were hood (58%), gloves (22%), and earflaps (22%). Regular cleaning of gear was not practiced by 39% of burned respondents and 46% had not had their gear sized within 2 years. Serious burns were reported by 41% of respondents. Mean burn size was 7% total body surface area (TBSA), and 11% reported self-treating their burns, including 63.5% who continued to work despite suffering a 2nd or 3rd degree burn injury. Only 17% were treated at a burn center, and this group missed anywhere from two shifts to 8 months of work. CONCLUSIONS: Firefighters risk injury by omitting gear and not adhering to National Fire Protection Association (NFPA) guidelines on gear sizing, maintenance, and station wear. Firefighters also frequently self-treat serious burns despite unique considerations regarding re-injury. National trends related to gear use and injury risk should be studied further, and standards should be developed for ensuring safe return to work.

RESUMO

Approximately 60,000 to 70,000 firefighters suffer work-related injuries per year in the United States. Approximately 10% of these injuries occur from burns or smoke inhalation. Previous analyses of the National Burn Repository (NBR) suggest that not all records of firefighter injuries are being captured. Therefore, an additional field was added to the NBR in 2016 to designate if the injury was sustained by a firefighter on duty. The purpose of this study is to evaluate whether the revisions have increased the number of firefighters included in the NBR. Postintervention NBR records from 2016 to 2017 were reviewed and were compared with the data from the previous NBR analyses before the database was modified, 2002 to 2010. The percentage of total U.S. injuries was determined for each time period by dividing the number of NBR entries by the total number of injuries in the United States according the National Fire Protection Agency statistics. The rate of capture was compared between the two time periods. A descriptive analysis of the new data set was then performed. The revised NBR captured 102 firefighter injuries in 2016 to 2017 (a mean of 51), in contrast to a mean of 52.5 per year in the older data set. The total rate of data capture increased from 0.8% of total injuries to 1.22%, as the total number of injuries in the United States decreased. Thirty burn centers reported treating a firefighter injury, compared with 46 over the 9-year period of the previous analysis. Size of burn injury was captured on 68 of 102 patients. Eighty-eight percent had an injury <10% TBSA, 29 patients suffered inhalation injury, and there was no mortality. The revisions in the National Burn Repository have improved the database's ability to provide information related to firefighter burn injury. Preliminary data suggests that rate of NBR capture has increased by approximately 50% as a percentage of total injuries across the United States. However, long-term data is still lacking which will assist in developing targets for outreach, education, and prevention measures.

RESUMO

Lubricating agents facilitate effective harvesting of split-thickness skin grafts. Multiple agents, including water-based gel, mineral oil, glycerin, and poloxamer 188, have been utilized in this capacity. The agent selected is typically at the discretion of the provider and institution, as a single "ideal" lubricant remains to be objectively established. Furthermore, a recent discontinuation of Shur-Clens® Skin Wound Cleanser1 (a wound cleansing solution consisting of the surfactant poloxamer 188) has prompted the search for a suitable substitute for many providers. The purpose of this study is to directly compare five lubricants (including a novel surgical lubricant-based solution) to select a preferred agent. Four practitioners blindly tested five lubricants while harvesting a split-thickness skin graft on a porcine skin model (glycerin, mineral oil, saline, poloxamer 188, and a novel lubricant solution created with surgical lube and sterile water). The results were recorded on a Likert scale where 1 indicated poor performance and 5 indicated excellent performance. Data were pooled, and means were compared with analysis of variance and post hoc Tukey test. The cost of each lubricating solution was also reported. Mean scores for each of the solutions were as follows: dry control = 1.1 ± 0.1; glycerin = 2.62 ± 1.02, saline = 3.88 ± 0.81, mineral oil = 3.75 ± 1.00, novel water-based lubricant solution = 4.63 ± 0.71, and poloxamer 188 = 3.88 ± 0.81. All solutions were superior to dry control (P < .01). Glycerin was noted to have statistically lower scores than all of the other solutions (P < .01). The novel water-based surgical lubricant solution had significantly higher mean scores than both glycerin (P < .01) and mineral oil (P < .05). Each solution was compared according to dollars per 100cc with glycerin and Shur-Clens® representing the most expensive options at almost $3/100cc and saline the least expensive at less than $0.15/100cc. In a porcine skin model, the novel water-based surgical lubricant solution had the best performance. It was statistically superior to glycerin and mineral oil and was also found to be the most cost-effective option in terms of overall performance compared with relative cost. Glycerin had the worst performance with statistically lower scores than all other solutions. Glycerin was also found to be the least cost-effective due to a large discrepancy between high cost and low overall performance. Saline performed better than expected. These results may be skewed due to the inherently greasy nature of the butcher shop porcine skin, creating limitations and decreasing the fidelity of the model. In a search for the "ideal" lubricant, other models should be further studied.

RESUMO

Over 20 million Americans have abused inhalants at least once in their lifetime. It is widely known that "huffing" increases risk for liver disease, renal failure, hypoxia, respiratory failure, dysrhythmias, and cardiac arrest. However, it is lesser known that inhalants can also cause thermal or frostbite injury. This study is a review of 2003 to 2012 National Burn Repository (NBR) records with a query for "huff," "inhalant," and corresponding ICD-9 codes. The NBR represents the cumulative data of subjects presenting to regional burn centers throughout the nation. Twenty-eight cases of inhalant injury were found. Approximately one-third were due to frostbite secondary to cold liquids exiting aerosol cans. The remaining two-third were due to thermal injury when the flammable solvent ignited. Median burn size was 3% total BSA (TBSA). Eight patients suffered inhalation injuries and one patient died. Although the median burn size of these patients was relatively small, some had significant injuries requiring long hospital length of stay. Direct costs of healthcare and indirect costs of lost wages make inhalant injury a significant public health problem. Multidisciplinary governmental efforts should be focused on prevention, education, recognition, and early intervention when inhalant abuse is suspected.

RESUMO

OBJECTIVE: Nebulized heparin has been proposed to improve pulmonary function in patients with inhalation injuries. The purpose of this study was to evaluate the impact of nebulized heparin with N-acetylcysteine (NAC) and albuterol on the duration of mechanical ventilation in burn patients. METHODS: This is a retrospective study evaluating mechanically ventilated adult patients admitted to a regional burn center with inhalation injury. Outcomes were compared between patients who were prescribed a combination of nebulized heparin with NAC and albuterol versus similar patients who did not. RESULTS: A total of 48 patients met inclusion criteria (heparin n = 22; nonheparin n = 26). Patients in the nonheparin group had higher percentage of total body surface area (TBSA) burned (29.00 [5.75-51.88] vs 5.25 [0.50-13.25] %TBSA; P = .009), longer duration of mechanical ventilation (6.50 [2.75-17.00] vs 3.00 [1.00-8.25] days; P = .022), and longer intensive care unit length of stay (LOS) (3.00 [3.00-28.75] vs 5.50 days [2.00-11.25]; P = .033). Upon regression, use of heparin was the only variable associated with reducing the duration of mechanical ventilation ( P = .039). CONCLUSION: Nebulized heparin in combination with NAC and albuterol was associated with a significant reduction in the duration of mechanical ventilation.

RESUMO

The United States Fire Administration (USFA) provides high-quality data for firefighter deaths (FFDs), but until now these data have not been analyzed for temporal trends. This analysis explores FFDs between 1990 and 2016 to determine high-risk groups for outreach and training. Mortality rates were calculated using USFA information compared against the total number of deaths per year. Rates were compared between 1990-2009 (early period) and 2010-2016 (recent period). Multinomial logistic regression was used to determine predictors of death in firefighters (FFs) by age group (≤45 and >45 years old) and by work status (career vs volunteer). Analysis of 3159 FFDs revealed a decline in crude-rate mortality between 1990-2009 and 2010-2016 (47.4 vs 35 FF deaths per million, P < .0001). FFs of ≤45 years old were less likely to die in the 2010s than in the 1990s-2000s (13.7 vs 24.7 FF deaths per million, P = .0002). Trauma-related deaths decreased (13.1 vs 8.1, P = .0003), whereas CV-related deaths remained constant (19.4 vs 19.5, P = .24). Regression analysis determined that volunteer FFs were more likely to die from burns (OR 1.7, CI: 1.2-2.4, P < .0001) and trauma (OR 1.8, CI: 1.5-2.2, P < .0001) than career FFs. Younger FFs were also more likely to die from burns (OR 10.4, CI: 6.9-15.6, P < .0001) and trauma (OR 6.5, CI: 5.4-7.8, P < .0001). Although overall FFDs were lower after 2010, younger and volunteer FFs saw an increase in burn and trauma-related mortality. Cardiovascular-related fatalities were consistent throughout the study. Future research should continue to make use of high-standard data to track FFDs and efficacy of interventions.

RESUMO

Mafenide acetate is an effective but costly antimicrobial solution used for burn wounds. The package insert instructs the user to discard unused solution within 48 hours of opening. The purpose of this study is to evaluate the antimicrobial activity of mafenide acetate beyond 48 hours after reconstitution, to possibly reduce cost by eliminating product waste. Staphylococcus aureus and Pseudomonas aeruginosa isolates were used to seed Mueller-Hinton agar plates. Filter paper disks were then saturated with 5% mafenide acetate at 0, 2, 7, 14, 30, and 60 days after reconstitution. Disks were then placed on the seeded agar plates and incubated. After incubation, the zone of inhibition around each plate was measured. A zone of inhibition of 2 mm or greater was indicative of susceptibility. Mafenide acetate remained efficacious, with a zone of inhibition of >2 mm to both organisms at 0, 2, 7, 14, 30, and 60 days after mafenide acetate reconstitution. This in vitro study demonstrates that the antimicrobial activity of mafenide acetate remains present for at least 60 days after reconstitution. Unused mafenide may not need to be discarded at 48 hours after opening. Reducing wasted product has the potential to translate into cost savings.

RESUMO

The National Burn Repository (NBR) is divided into four regions for the purposes of data collection and reporting. Based on the 2010 U.S. census data, the states that represent the southern region have the highest overall population: 102,657,250 people vs 64,377,806 for the North. Despite being almost twice as heavily populated, the South has fewer NBR entries than the North: 53,629 vs 62,499. The South has also significantly fewer entries than would be expected based on its relative population size compared with the entire United States (chi-square test, P < .001). This finding may represent a disparity in access to burn centers in the South, fewer total burns, or a reporting bias.

RESUMO

In 2015, 68,085 firefighters suffered work-related injury, according to estimates from the U.S. Fire Administration. Despite these figures, only 473 firefighter injuries were captured in the National Burn Repository (NBR) over a 9-year period. Of the 96 burn centers that contribute data, 50 did not report a single firefighter burn injury. Two thirds of the injuries were reported by two individual centers. The NBR does not capture the full scope of firefighter injuries, likely due to issues with reporting, data extraction, and firefighters seeking burn care at facilities without dedicated burn centers. Firefighters have unique considerations when it comes to planning return to work in a high-heat environment after thermal injury. Firefighters should have access to burn centers when seeking treatment for burn injury.

RESUMO

BACKGROUND: Diagnosing the extremes of superficial burns and full-thickness burns is straightforward. It is in the middle ground of partial-thickness burns where the diagnostic difficulties emerge; it can take up to 3 to 5 days for signs of healing to appear. We hypothesize that cooling partial-thickness burns and tracking the rate of rewarming will immediately reflect the condition of the burn: shallow partial-thickness burns that retain cell health and blood flow will rewarm rapidly, and deeper burns with damaged microvessels will rewarm slowly. STUDY DESIGN: We enrolled 16 patients with isolated, partial-thickness burns on their extremities who were diagnosed as indeterminate by our burn surgeon. Within 24 hours after presentation, room-temperature saline was poured over the burn as a cooling challenge. An infrared camera that was sensitive to body temperature produced false-color images showing pixel-by-pixel temperatures. A time-lapse recording from the infrared camera images taken as the burn rewarmed produced a time-temperature curve that reflected the kinetics of rewarming. The outcomes variable was whether or not the patient received a skin graft, which was determined 72 hours after presentation. RESULTS: The method correctly predicted whether or not the patient required a skin graft. CONCLUSIONS: Here we report a new technique that permits determination of wound viability much earlier than clinical examination. Due to the simplicity of the method, non-experts can successfully perform the technique on the first day of the burn and make the correct diagnosis and decision to graft or not to graft.
