Early Enzymatic Burn Debridement: Results of the DETECT Multicenter Randomized Controlled Trial.

Since 1970 surgeons have managed deep burns by surgical debridement and autografting. We tested the hypothesis that enzymatic debridement with NexoBrid would remove the eschar reducing surgery and achieve comparable long-term outcomes as standard of care (SOC). In this Phase 3 trial, we randomly assigned adults with deep burns (covering 3-30% of total body surface area [TBSA]) to NexoBrid, surgical or nonsurgical SOC, or placebo Gel Vehicle (GV) in a 3:3:1 ratio. The primary endpoint was complete eschar removal (ER) at the end of the debridement phase. Secondary outcomes were need for surgery, time to complete ER, and blood loss. Safety endpoints included wound closure and 12 and 24-months cosmesis on the Modified Vancouver Scar Scale. Patients were randomized to NexoBrid (n = 75), SOC (n = 75), and GV (n = 25). Complete ER was higher in the NexoBrid versus the GV group (93% vs 4%; P < .001). Surgical excision was lower in the NexoBrid vs the SOC group (4% vs 72%; P < .001). Median time to ER was 1.0 and 3.8 days for the NexoBrid and SOC respectively (P < .001). ER blood loss was lower in the NexoBrid than the SOC group (14 ± 512 mL vs 814 ± 1020 mL, respectively; P < .0001). MVSS scores at 12 and 24 months were noninferior in the NexoBrid versus SOC groups (3.7 ± 2.1 vs 5.0 ± 3.1 for the 12 months and 3.04 ± 2.2 vs 3.30 ± 2.76 for the 24 months). NexoBrid resulted in early complete ER in >90% of burn patients, reduced surgery and blood loss. NexoBrid was safe and well tolerated without deleterious effects on wound closure and scarring.

Analysis of real-world length of stay data and costs associated with use of autologous skin cell suspension for the treatment of small burns in U.S. centers.

BACKGROUND: Autologous skin cell suspension (ASCS) is a treatment for acute thermal burn injuries associated with significantly lower donor skin requirements than conventional split-thickness skin grafts (STSG). Projections using the BEACON model suggest that among patients with small burns (total body surface area [TBSA]<20 %), use of ASCS± STSG leads to a shorter length of stay (LOS) in hospital and cost savings compared with use of STSG alone. This study evaluated whether data from real-world clinical practice corroborate these findings. MATERIALS AND METHODS: Electronic medical record data were collected from January 2019 through August 2020 from 500 healthcare facilities in the United States. Adult patients receiving inpatient treatment with ASCS± STSG for small burns were identified and matched to patients receiving STSG using baseline characteristics. LOS was assumed to cost $7554/day and to account for 70 % of overall costs. Mean LOS and costs were calculated for the ASCS± STSG and STSG cohorts. RESULTS: A total of 151 ASCS± STSG and 2243 STSG cases were identified; 63.0 % of patients were male and the average age was 44.2 years. Sixty-three matches were made between cohorts. LOS was 18.5 days with ASCS± STSG and 20.6 days with STSG (difference: 2.1 days [10.2 %]). This difference led to bed cost savings of $15,587.62 per ASCS± STSG patient. Overall cost savings with ASCS± STSG were $22,268.03 per patient. CONCLUSIONS: Analysis of real-world data shows that treatment of small burn injuries with ASCS± STSG provides reduced LOS and substantial cost savings compared with STSG, supporting the validity of the BEACON model projections.

Burn Resuscitation Practices in North America: Results of the Acute Burn ResUscitation Multicenter Prospective Trial (ABRUPT).

OBJECTIVES: ABRUPT was a prospective, noninterventional, observational study of resuscitation practices at 21 burn centers. The primary goal was to examine burn resuscitation with albumin or crystalloids alone, to design a future prospective randomized trial. SUMMARY BACKGROUND DATA: No modern prospective study has determined whether to use colloids or crystalloids for acute burn resuscitation. METHODS: Patients ≥18 years with burns ≥ 20% total body surface area (TBSA) had hourly documentation of resuscitation parameters for 48 hours. Patients received either crystalloids alone or had albumin supplemented to crystalloid based on center protocols. RESULTS: Of 379 enrollees, two-thirds (253) were resuscitated with albumin and one-third (126) were resuscitated with crystalloid alone. Albumin patients received more total fluid than Crystalloid patients (5.2 ± 2.3 vs 3.7 ± 1.7 mL/kg/% TBSA burn/24 hours), but patients in the Albumin Group were older, had larger burns, higher admission Sequential Organ Failure Assessment (SOFA) scores, and more inhalation injury. Albumin lowered the in-to-out (I/O) ratio and was started ≤12 hours in patients with the highest initial fluid requirements, given >12 hours with intermediate requirements, and avoided in patients who responded to crystalloid alone. CONCLUSIONS: Albumin use is associated with older age, larger and deeper burns, and more severe organ dysfunction at presentation. Albumin supplementation is started when initial crystalloid rates are above expected targets and improves the I/O ratio. The fluid received in the first 24 hours was at or above the Parkland Formula estimate.

Length of Stay and Costs with Autologous Skin Cell Suspension Versus Split-Thickness Skin Grafts: Burn Care Data from US Centers.

INTRODUCTION: Autologous skin cell suspension (ASCS) significantly reduces donor skin requirements versus conventional split-thickness skin grafts (STSG) for thermal burn treatment. In analyses using the Burn-medical counter measure Effectiveness Assessment Cost Outcomes Nexus (BEACON) model, ASCS was associated with shorter hospital length of stay (LOS) and cost savings versus STSG. This study hypothesized that daily practice data from the USA would support these findings. METHODS: Electronic medical record data from 500 healthcare facilities (January 2019-August 2020) were used to match adult patients who received inpatient burn treatment with ASCS (± STSG) to patients treated with STSG alone on the basis of sex, age, percent total body surface area (TBSA), and comorbidities. Based on BEACON analyses, LOS was assumed to represent 70% of total costs and used as a proxy to assess the data. Mean LOS, costs, and the incremental revenue associated with inpatient capacity changes were calculated. RESULTS: A total of 151 ASCS and 2443 STSG patients were identified: 63.0% were male and average age was 44.5 years. Eight-one matches were made between cohorts. LOS was 21.7 days with ASCS and 25.0 days with STSG alone (difference 3.3 days [13.2%]). LOS was lower with ASCS than STSG in four of five TBSA intervals. The LOS difference led to hospital bed cost savings of $25,864 per ASCS patient; overall cost savings were $36,949 per patient. Similar cost savings were observed in TBSA groupings < 20% and ≥ 20%. The reduced LOS with ASCS translated into an increased capacity of 2.2 inpatients/bed annually, which increased hospital revenue by $92,283/burn unit bed annually. CONCLUSIONS: Real-world data show that ASCS (± STSG) is associated with reduced LOS and cost savings versus STSG alone across all burn sizes, supporting the validity of the BEACON analyses. ASCS use may also increase patient capacity and throughput, leading to increased hospital revenue.

Autologous skin cell suspension (ASCS) is a treatment for thermal skin burn injuries that can be used alone or in combination with split-thickness skin grafts (STSG), the conventional standard of care. Projections using the Burn-medical counter measure Effectiveness Assessment Cost Outcomes Nexus (BEACON) model indicate that ASCS leads to shorter hospital length of stay (LOS) and overall cost savings compared with STSG alone. These model findings are supported by benchmarking study data from a limited sample of US burn centers. The current study aimed to understand whether the BEACON projections are supported by daily clinical practice data from US healthcare facilities. Using electronic medical record data, we matched patients who received ASCS ± STSG from January 2019 to August 2020 to those receiving STSG alone on the basis of demographic and clinical factors. Data analysis showed that hospital LOS was shorter (3.3 days) with ASCS ± STSG than STSG alone, a difference associated with a hospital bed cost savings of $25,864 per ASCS patient. Overall cost savings, which included nursing time and other costs, were $36,949 per patient. Analysis of patients with burns comprising total body surface areas less than 20% or at least 20% showed cost savings in both groups. The reduced LOS with ASCS also translated into the ability to treat 2.2 more patients per hospital bed per year, which was projected to increase hospital earnings. These real-world findings support those of modeling analyses, indicating that use of ASCS ± STSG is associated with meaningful clinical and economic benefits compared with use of STSG alone.

"More than Scabs and Stitches": An Interview Study of Burn Survivors' Perspectives on Treatment and Recovery.

Sustaining a burn injury often results in a life-long recovery process. Survivors are impacted by changes in their mobility, appearance, and ability to carry out activities of daily living. In this study, we examined survivors' accounts of their treatment and recovery in order to identify specific factors that have had significant impacts on their well-being. With this knowledge, we may be better equipped to optimize the care of burn patients. We conducted inductive, thematic analysis on transcripts of in-depth, semistructured interviews with 11 burn survivors. Participants were purposefully selected for variability in age, gender, injury size and mechanism, participation in peer support, and rurality. Survivors reported varied perceptions of care quality and provider relationships. Ongoing issues with skin and mobility continued to impact their activities of daily living. Many survivors reported that they did not have a clear understanding or realistic expectations of the recovery process. Wound care was often described as overwhelming and provoked fear for many. Even years later, trauma from burn injury can continue to evolve, creating fears and impediments to daily living for survivors. To help patients understand the realistic course of recovery, providers should focus on communicating the nature of injury and anticipated recovery, developing protocols to better identify survivors facing barriers to care, and referring survivors for further support.

Preserving Vision: Rethinking Burn Patient Monitoring to Prevent Orbital Compartment Syndrome.

Burn patients receiving aggressive fluid resuscitation are at risk of developing orbital compartment syndrome (OCS). This condition results in elevated orbital pressures and can lead to rapid permanent vision loss. Risk factors and monitoring frequency for OCS remain largely unknown. A retrospective review was therefore conducted of admitted burn patients evaluated by the ophthalmology service at an American Burn Association verified Burn Treatment Center. Demographic, burn, examination, and fluid resuscitation data were compared using two-sided t-tests, Fisher's exact tests, and linear regression. Risk factors for elevated intraocular pressures (IOPs; a surrogate for intraorbital pressure) in patients resuscitated via the Parkland formula were found to be total body surface area (% TBSA) burned, resuscitation above the Ivy Index (>250 ml/kg), and Parkland formula calculated volume. Maximum IOP and actual fluid resuscitation volume were linearly related. Analysis of all patients with elevated IOP found multiple patients with significant IOP increases after initial evaluation resulting in OCS within the first 24 hours postinjury. While %TBSA, Ivy Index, and resuscitation calculated volume are OCS risk factors in burn patients, two patients with facial burns developed OCS (25% of all patients with OCS) despite not requiring resuscitation. Orbital congestion can develop within the first 24 hours of admission when resuscitation volumes are the greatest. In addition to earlier and more frequent IOP checks in susceptible burn patients during the first day, the associated risk factors will help identify those most at risk for OCS and vision loss.

The Impact of Adverse Childhood Experiences on Burn Outcomes in Adult Burn Patients.

Adverse childhood experiences (ACEs), including child maltreatment and household dysfunction, define adverse events that occur before 18 years of age. National and state data show that between 12.5 and 14.5% of the adult population report ≥4 ACEs (HIGH-ACE), respectively. HIGH-ACEs are associated with more chronic health problems. To date, the interaction between ACEs and burn injuries has not been studied. Herein, we sought to define the ACE exposure in our burn patients and its impact on early outcomes. Inpatient and outpatient adult burn survivors (≥18 years of age) were enrolled. Subjects completed surveys assessing adverse experiences (ACEs-18), needs, strengths, and resiliency at consent, and pain, depression, post-traumatic stress disorder (PTSD), and social participation surveys at 2 weeks to 3 months postinjury. Demographics, burn, and hospital course data were also collected. Chi-square and student's t-tests were used for descriptive analysis and to compare the groups (HIGH-ACE vs LOW-ACE). The HIGH-ACE group (n = 24; 45.3%) reported more depressive symptoms (P < .04) than the LOW-ACE group (n = 29, 54.7%). HIGH-ACE patients were less resilient when facing stressful events (P ≤ .02) and more likely to screen positive for probable PTSD (P = .01) and to score lower on the Life Impact Burn Recovery Evaluation Profile (LIBRE Profile), which assesses for social participation, in the domain of Family and Friends (P = .015). Our exploratory study suggests that ACE screening may help detect burn patients at risk for a more complicated recovery, thereby promoting personalized assistance in recovery.

Burn Survivor Quality of Life and Barriers to Support Program Participation.

After a serious burn, re-entry into family life, society, and work can be incredibly difficult. Support services such as professional counseling and peer support play a key role for recovering survivors. Herein, we sought to identify support service participation rates, barriers to participation, and quality of life (QOL) among burn survivors treated at a regional burn center. A survey of burn survivors over 18 years old treated for a burn for 5 days or greater between 2006 and 2016 were invited to participate in a survey. The three-part survey contained sections covering demographics, questions regarding support program (SP) awareness, needs and participation, and QOL surveys. Univariate and multivariate regression analyses were performed to identify factors related to SP participation and QOL scores. Nine hundred sixty-eight patients were eligible; 150 responses were received. Over one third (40, 31%) of the responding survivors wanted support, but only half of those (23, 17%) participated in SPs. Distance and awareness of the available programs were two barriers to participation. Those attending SPs were more likely to have had larger burns (OR = 3.7, P = 0.05) and visible burns (OR = 7.5, P = 0.031). Lower scores on selected QOL scales were associated with burns more than 30%, visible burns, female gender, time from burn, and age group. A sizable number of burn survivors want SPs. However, access to these services and advertising their existence are hurdles to overcome. Future burn survivor SPs should focus on psychosocial stresses identified in the QOL assessments.

The National Incidence and Resource Utilization of Burn Injuries Sustained While Smoking on Home Oxygen Therapy.

Considerable risk of burn injury exists for those patients on home oxygen therapy (HOT) who continue to smoke. In this study, the authors sought to establish the national incidence of burns incurred while smoking on HOT and to determine the resource utilization and sequelae of these injuries. A retrospective review of the American Burn Association's National Burn Repository was conducted to identify patients burned while on HOT during the years 2002 to 2011. Duplicate entries, as well as records of follow-up visits and readmissions, were removed. Univariate analysis was used to compare the differences between patients sustaining burn injuries related to HOT and patients with other mechanisms of injury. Multivariate analysis provided odds ratios for mortality controlling for all significant variables. The frequency of burns sustained on HOT significantly increased during the 10-year period reviewed and were associated with increased comorbidities and certain complications. Compared with non-HOT injuries, HOT injuries had higher incidence of inhalation injury and mortality. Inhalation injury was the strongest predictor of mortality in HOT burn injuries. The likelihood of poor prognosis was even more pronounced in patients who required intubation. Smoking was responsible for 83% of the HOT burn injuries described here. Therefore, smoking cessation counseling and treatment should be mandatory in all patients prescribed HOT.

Regional and national review of factors associated with burn wound cellulitis.

Burn wound cellulitis (BWC) is the second leading complication reported in burns. In this study we sought to identify demographic variables, burn factors, and other factors that may predispose patients to BWC. Regional data was obtained through retrospective medical record review of burn patients treated between May 2009 to April 2013 for BWC within 8 days of the injury. The patients were matched 1:2 with contemporaneously treated patients. Similarly, the National Burn Repository was queried to identify burn patients with BWC between the years 2002 to 2011, which were then compared to the remaining entries who did not have BWC reported. The data sets were analyzed separately. Univariate and multiple variable analyses were performed to evaluate risk factors for BWC. The risk factors that were consistent regionally and nationally were older age, male sex, African-American race (protective), lower extremity burns, scald burns, and full thickness burns. The treatment delay was only collected regionally, and was associated with an eight times increased risk. The factors that were inconsistent or significant in one sample only were smoking status, psychiatric conditions, upper extremity burns, and the place of injury. Cellulitis remains a significant problem for the burn community. Future prospective analyses need to clarify the impact of these factors as well as other factors on the development of BWC. Preventing BWC from occurring through earlier intervention or targeted prophylactic antibiotics may help reduce morbidity and decrease associated healthcare costs.

Genital burns in the national burn repository: incidence, etiology, and impact on morbidity and mortality.

OBJECTIVE: To better characterize national genital burns (GBs) characteristics using a large burn registry. We hypothesized that mortality and morbidity will be higher in patients with GBs. METHODS: The National Burn Repository, a large North American registry of hospitalized burn patients, was queried for patients with GB. Burn characteristics and mechanism, demographics, mortality, and surgical interventions were retrieved. Outcomes of interest were mortality, hospital-acquired infection (HAI), and surgical intervention on the genitalia. Adjusted odds ratios (aOR) for outcomes were determined with binomial logistic regression controlling for age, total burn surface area, race, length of stay, gender, and inhalation injury presence. RESULTS: GBs were present in 1245 cases of 71,895 burns (1.7%). Patients with GB had significantly greater average total burn surface area, length of stay, and mortality. In patients with GB, surgery of the genitalia was infrequent (10.4%), with the aOR of receiving surgery higher among men (aOR 2.7, P <.001) and those with third-degree burns (aOR 3.1, P <.002). Presence of a GB increased the odds of HAI (aOR 3.0, P <.0001) and urinary tract infections (aOR 3.4, P <.0001). GB was also an independent predictor of mortality (aOR 1.54) even after adjusting for the increased HAI risk. CONCLUSION: GBs are rare but associated with higher HAI rates and higher mortality after adjusting for well-established mortality risk factors. Although a cause and effect relationship cannot be established using these registry data, we believe this study suggests the need for special management considerations in GB cases to improve overall outcomes.

Long-term outcomes of patients with necrotizing fasciitis.

CONTEXT: Necrotizing fasciitis is an aggressive infection affecting the skin and soft tissue. It has a very high acute mortality. The long-term survival and cause of death of patients who survive an index hospitalization for necrotizing fasciitis are not known. OBJECTIVE: To define the long-term survival of patients who survive an index admission for necrotizing fasciitis. We hypothesize that survivors will have a shorter life span than population controls. DESIGN: Long-term follow-up of a registry of patients from 1989 to 2006 who survived a hospitalization for necrotizing fasciitis. Last date of follow-up was January 1, 2008. SETTINGS: A university-based Burn and Trauma Center. PATIENTS: A prospective registry of patients with necrotizing fasciitis has been collected from 1989 to 2006. This registry was linked to data from the Department of Health, Department of Motor Vehicles, and the University Hospital Medical Records Department in January 2008 to obtain follow-up and vital status data. INTERVENTION: None. MAIN OUTCOME MEASURES: Date and cause of death were abstracted from death certificates. Date of last live follow-up was determined from the medical record and by the last driver's license renewal. The death rate of the cohort was standardized for age and sex against 2005 statewide mortality rates. Cause of death was collated into infectious and noninfectious and compared with the statewide causes of death. Statistical analysis included standardized mortality rates, Kaplan-Meier survival curves, and Aalen's additive hazard model. RESULTS: Three hundred forty-five patients of the 377 in the registry survived at least 30 days and were analyzed. Average age at presentation was 49 years (range, 1-86; median, 49). Patients were followed up an average of 3.3 years (range, 0.0-15.7; median, 2.4). Eighty-seven of these patients died (25%). Median survival was 10.0 years (95% confidence interval: 7.25-13.11). There was a trend toward higher mortality in women. Twelve of the 87 deaths were due to infectious causes. Using three different statistical analytic techniques, there was a statistically significant increase in the long-term death rate when compared with population-based controls. Infectious causes of death were statistically higher than controls as well. CONCLUSIONS: Patients who survive an episode of necrotizing fasciitis are at continued risk for premature death; many of these deaths were due to infectious causes such as pneumonia, cholecystitis, urinary tract infections, and sepsis. These patients should be counseled, followed, and immunized to minimize chances of death. Modification of other risk factors for death such as obesity, diabetes, smoking, and atherosclerotic disease should also be undertaken. The sex difference in long-term survival is intriguing and needs to be addressed in further studies.

The effect of burn center and burn center volume on the mortality of burned adults--an analysis of the data in the National Burn Repository.

Regional variations of care, and improved outcomes with larger volumes, have been well described in the medical and surgical literature for a variety of conditions including heart surgery, vascular surgery, and orthopedic surgery. Burn care has not been recently subjected to such an analysis. The National Burn Repository (NBR) contains de-identified patient and burn center data to allow this analysis. The NBR was queried for adult burn patients admitted for an acute thermal burn injury. A multivariable regression analysis to identify risk of death was performed incorporating patient characteristics, de-identified burn center, and burn center volume. Patient characteristics such as age, size of burn, mechanism of burn, inhalation injury, race, and sex determine mortality. There is also a statistically significant difference in death rates when individual, de-identified centers are compared. This difference in care persists even when accounting for burn center volume. Analysis of registries like the NBR, insurance claims databases, and statewide hospital discharge databases may help identify opportunities to improve burn care. According to this analysis of data available in the NBR, burn mortality depends not only on patient characteristics but also where the patient is treated. Mortality does not linearly improve with burn center volume and plateaus with increasing burn center size. The optimal burn center size is a complicated and contentious question. Future discussions about burn center size and density should incorporate not only mortality but also the region's ability to absorb surges in volume, and the optimal "staffing" ratios for the multidisciplinary aspects of burn care.

The efficacy of hair and urine toxicology screening on the detection of child abuse by burning.

Abuse by burning is estimated to occur in 1 to 25% of children admitted with burn injuries annually. Hair and urine toxicology for illicit drug exposure may provide additional confirmatory evidence for abuse. To determine the impact of hair and urine toxicology on the identification of child abuse, we performed a retrospective chart review of all pediatric patients admitted to our burn unit. The medical records of 263 children aged 0 to 16 years of age who were admitted to our burn unit from January 2002 to December 2007 were reviewed. Sixty-five children had suspected abuse. Of those with suspected abuse, 33 were confirmed by the Department of Health and Human Services and comprised the study group. Each of the 33 cases was randomly matched to three pediatric (0-16 years of age) control patients (99). The average annual incidence of abuse in pediatric burn patients was 13.7+/-8.4% of total annual pediatric admissions (range, 0-25.6%). Age younger than 5 years, hot tap water cause, bilateral, and posterior location of injury were significantly associated with nonaccidental burn injury on multivariate analysis. Thirteen (39.4%) abused children had positive ancillary tests. These included four (16%) skeletal surveys positive for fractures and 10 (45%) hair samples positive for drugs of abuse (one patient had a fracture and a positive hair screen). In three (9.1%) patients who were not initially suspected of abuse but later confirmed, positive hair test for illicit drugs was the only indicator of abuse. Nonaccidental injury can be difficult to confirm. Although inconsistent injury history and burn injury pattern remain central to the diagnosis of abuse by burning, hair and urine toxicology offers a further means to facilitate confirmation of abuse.

Emergence of the USA300 strain of methicillin-resistant Staphylococcus aureus in a burn-trauma unit.

Community-associated methicillin-resistant Staphylococcus aureus (MRSA), particularly USA300, is a major pathogen in the outpatient setting. We suspected that USA300 had been introduced into our burn-trauma unit (BTU) when three burn patients presented with numerous simultaneous abscesses. We did molecular typing on 206 MRSA isolates from all patients on the BTU who had MRSA isolated from either nares cultures or clinical specimens obtained between April 11, 2002 and October 24, 2006. We reviewed medical records for all patients who had USA300 and for 75 control patients. Twenty-five of 206 (12.1%) patients who were colonized (n = 3) or infected (n = 22) with MRSA had USA300. Thirteen patients had abscesses drained surgically and eight had necrotizing fasciitis excised. Seven patients had burns (mean burn size 11.8 +/- 3.4%), of who four (66.7%) acquired numerous simultaneous (3-33) abscesses. Fourteen patients acquired USA300 outside of the BTU, and three acquired this strain on the BTU. Cases were more likely to have been hospitalized or to have had an operation in the 6 months before they were hospitalized than were controls (P = .001 for both). To our knowledge, this is the first study to describe numerous simultaneous MRSA abscesses in burn patients. The MRSA strain USA300 may be introduced onto burn units from the community by patients admitted with skin and soft tissue infections, especially abscesses and necrotizing fasciitis. Burn patients may be at risk for numerous abscesses with USA300, because they have open wounds and their immune systems may be compromised.

Methamphetamine-related burns in the cornbelt.

Methamphetamine (MA) is a highly addictive drug that is easily manufactured from everyday household products and chemicals found at local farm stores. The proliferation of small MA labs has led to a dramatic increase in patients sustaining thermal injury while making and/or using MA. We hypothesized that these patients have larger injuries with longer hospital stays, and larger, nonreimbursed hospital bills compared with burn patients not manufacturing or using MA. In a retrospective case-control study, all burn patients >or=16 years of age admitted to our burn center from January 2002 to December 2005 were stratified into two groups based on urine MA status. Of the 660 burn patients >or=16 years of age admitted during this 4 year period, urine drug screens were obtained at admission on 410 patients (62%); 10% of urine drug screens were MA (+). MA (+) patients have larger burns compared with MA (-) patients (9.3 vs 8.6% body surface area burns), have higher rates of inhalation injuries (20.4 vs 9.3%, P = .015), and more nonthermal trauma (13.0 vs 3.1%, P = .001). When compared with MA (-) patients, MA (+) patients require longer hospital stays (median 9.5 vs 7.0 days, P = .036), accrue greater hospital bills per day (dollars 4292 vs dollars 2797, P = .01), and lack medical insurance (66.7 vs 17.7%, P < .0001). The epidemic of MA use and its manufacture mandates that burn centers monitor patients for MA use and develop and institute protocols to ensure proper care of this increasingly costly population.

A prospective analysis of trash, brush, and grass burning behaviors.

Burn injuries sustained during residential trash, brush, and grass burning cause significant morbidity and mortality in rural areas. To further prevention efforts, we surveyed individuals who incurred injuries from residential burning. Thirty-six individuals injured while burning trash, brush, or grass from June 2003 through September 2005 were asked to respond to a self-administered written survey. Injury related questions revealed that the majority of those injured were burning brush (21 of 35, 60.0%) in an open space (19 of 35, 54.2%) with the addition of accelerants (27 of 36, 75%). Survey questions regarding usual burning practices revealed almost two-thirds burned either brush or a mixture of brush and trash (23 of 36, 63.9%). Eighty percent of those who were injured desired to change their behavior (25 of 35, 80%). Approximately two-thirds would consider asking for help with burning if it were provided (22 of 34, 64.7%). Our survey shows that acceptable alternatives to burning varied depending on the material that was burned. As the majority of respondents usually burned brush or a mixture of brush and trash, an acceptable trash removal system should also include brush pickup. As residential burning continues presently, injury prevention efforts are essential and should focus on the misuse of gasoline, uniform safety standards for gasoline cans, and dissemination of safe burning practices.

Effect of a fish oil and arginine-fortified diet in thermally injured patients.

Burn injury induces a hypercatabolic inflammatory state, predisposing burn patients to malnutrition, poor wound healing, and infectious complications. We conducted this study to determine what effect a diet fortified with fish oil and arginine (FAD) would have on wound healing in a thermally injured population. Twenty-three thermally injured patients were enrolled in this randomized double blind enteral feeding study from July 2002 to August 2004. All study patients received isonitrogenous enteral intragastric feeding within 48 hours of admission. Patients were randomized to our standard diet (STD, ProBalance with Promix, Probalance from Nestlé, Glendale, CA; ProMix R.D., Navaco Laboratories, Phoenix, AZ) or a diet fortified with fish oil and arginine (FAD, Crucial, Nestlé Nutrition Glendale, CA) Diets were advanced as tolerated to meet 100% of estimated needs. The primary endpoint of the study was time to heal the first donor site. There were no statistical differences between the study groups with respect to baseline characteristics. Both diets were well tolerated, and there were no differences in the daily total kilocalories or protein intake per kilogram between the two diet groups throughout the study. Although nonsignificant, the patients in the FAD group showed a slightly faster healing time than those in the STD group (10.8 +/- 2.7 days vs 12.3 +/- 5.2 days, respectively). This trend was further accelerated when those with body surface area burns less than 30% were examined (patients with body surface area burns <30% in the FAD healed in 9.0 +/- 1.7 vs corresponding patients in the standard group who healed in 12.2 +/- 6.2, P = .63). Patients in the FAD group trended to more infections and more adverse complications. The adverse complications were predominantly associated with inhalation injuries. The role of fortified enteral diets in the outcomes of thermally injured patients deserves further study. Such a future study should be conducted in a multicenter trial and involve inhalation injury stratification systems to accurately score and randomize patients for inhalation injury. Finally, the frequency and pattern of infections in patients receiving fortified enteral diets deserves further evaluation.
