The Pentagon attack of September 11, 2001: a burn center's experience

On September 11, 2001, an airplane flown by terrorists crashed into the Pentagon, causing a mass casualty incident with 189 deaths and 106 persons treated for injuries in local hospitals. Nine burn victims and one victim with an inhalation injury only were transported to the burn center hospital. The Burn Center at Washington Hospital Center admitted and treated the acute burn patients while continuing its mission as the regional burn center for the Washington DC region. Eight of the nine burn patients survived. Lessons learned include 1) A large-volume burn center hospital can absorb nine acute burns and maintain burn center and hospital operations, but the decision to keep or transfer burn patients must be tempered with the reality that several large burns can double or triple the work load for 2 to 3 months. 2) Transfer decisions should have high priority and be timely to ensure optimum care for the patients without need for movement of medical personnel from one burn center to another. 3) The reserve capacity of burn beds in the United States is limited, and the burn centers and the American Burn Association must continue to seek recognition and support from Congress and the federal agencies for optimal preparedness.     

An effective burn prevention program initiated by a recovered burn patient group

The US death rate from house fires has remained constant during the past 50 years despite a sharp decline in mortality from other fires and causes of burns. The concensus is that smoke alarms can effectively decrease the incidence of this lethal type of burn injury. Our organization of recovered burn patients has focused its efforts around procuring and installing smoke alarms in areas of substandard housing, which predominantly account for house fire deaths and injuries in St. Louis. This effort has resulted in an effective burn prevention program ("Alarms for Life"), which also serves as a model for other communities.     

The evolution of burn care facilities in the United States.

This historical review documents the establishment and current status of specialized burn care facilities opened in the United States since 1947, describes trends in their physical configuration and burn bed availability and discusses the terms used to classify those facilities. Lists of active burn care facilities were reviewed, including primarily the Burn Care Resource directories of the American Burn Association, which date back to 1976, along with the results of special surveys carried out by the authors in 1992 and 2006. Of the burn facilities at 175 US hospitals which had reported the presence of specialized burn beds since 1947, 25 had closed before 1992, 153 have been active as recently as 1992, and 125 were active as of early 2007. Between 1979 and 2007, total burn beds listed as available in annual surveys of hospitals reporting specialized burn care facilities ranged between about 1700 and 1800 beds. Average burn beds in those facilities increased from approximately 11.2 to 14.4. Specialized burn care facilities provide burn care in various configurations of units dedicated primarily to burns and those shared with other patients. Despite the closing of 50 such facilities in recent decades, total reported burn beds in the United States have remained essentially stable during the past 30 years. Issues related to concentrating burn beds in a smaller number of facilities and external factors affecting their past and future operations merit additional review.     

A seven-year burn unit experience in Kayseri, Turkey: 1996 to 2002

A retrospective multifactorial epidemiological study of 742 patients admitted to Erciyes University Medical Faculty Burn Unit during a 7-year period between 1996 and 2002 is presented. The overall male-to-female ratio was 1.88:1. The highest-risk age group of burn injuries was 0 to 6 years (48.6%), with the greatest number of injuries occurring to children who were 2 to 3 years of age. Seasonal variations had no influence on the increased number of admissions to the burn unit. Scalding was the major cause of pediatric burns. Flame burns were the most frequent cause of burns in adults and the second-leading cause in children. Seventy-eight of the 742 patients died, with a mortality rate of 7.8 % in children and 12.6% and 19.23% in adult males and females, respectively. The overall mortality rate was 10.5%.     

Evaluation of a burn prevention program in a public school system.

The "Learn Not to Burn" prevention program is a burn prevention curriculum sponsored by the North Carolina Jaycee Burn Center, the State Department of Public Instruction, and the North Carolina Department of Insurance Fire and Rescue Division. The goal of the program is to reduce burn-related deaths and injuries in North Carolina through burn prevention education by making the "Learn Not to Burn" curriculum available to primary school children across the state at no cost to the schools. The curriculum instrument is a reusable notebook that provides a means for teachers to integrate burn prevention into regular class subject areas. At the time of initiation of this study approximately 70% of the school systems in North Carolina had been provided with the "Learn Not to Burn" curriculum.     

Acute renal failure in intensive care burn patients (ARF in burn patients).

The purpose of this study was to establish the incidence and mortality of burn patients with acute renal failure (ARF) at the Helsinki Burn Centre and to analyze the associated factors. The files of 238 intensive care (ICU) patients of a total of 1380 burn patients admitted to our institution between November 1988 and December 2001 were studied retrospectively. Of all admitted burn patients, 17.2% needed ICU. According to our criteria (S-Cr >120 micromol/l = 1.4 mg/dl), 39.1% of the ICU patients suffered from ARF and one in three of these required renal replacement therapy. The proportion of all admitted burn patients requiring renal replacement therapy was 2.3%. The mortality of ICU patients with ARF was 44.1% whereas that of patients without ARF was only 6.9%. Renal function recovered in all survivors. The nonsurvivors had a larger burned total body surface area, were older, and had more inhalation injuries and a higher abbreviated burn severity index score. The prognosis for patients with early ARF was worse than that for patients with late ARF. Rhabdomyolysis caused by flame injury was associated with high mortality. In this study we observed that ARF is associated with higher mortality even in minor burns when compared with patients without ARF. Flame burn with rhabdomyolysis and subsequent ARF predicts very poor survival. If a patient with severe ARF survives, the renal failure recovers over time.     

When a hero becomes a patient: firefighter burn injuries in the National Burn Repository

Firefighters receive significant training and are outfitted with state-of-the-art protective equipment. However, given the unpredictable nature of their work environment, injuries still occur. The National Burn Repository (NBR) was viewed as a resource for defining the epidemiology of these injuries on a national level and to identify predictive factors for outcomes in this population. The NBR was queried for the occupation of "firefighter" for the years 1990-2008. Records were screened for completeness, and 597 patients were identified for analysis. Data examined included demographics, %TBSA burn, length of stay (LOS), injury circumstance, and disposition. Multiple linear regression models were created to determine factors related to outcome measures. The majority of patients were white (84%) and male (96%). The mean age was 35 years. Most injuries were caused by fire/flame (73%). Only six deaths (1%) were reported. Most injuries were work-related (86%), and most patients were discharged home (92%). Inhalation injury was documented in 9% of patients. The mean LOS was 6.5 ± 11.3 days (median 2 days), and few patients had critical care requirements. The average %TBSA was 6 ± 11.7%. Patients with larger injuries had increased LOS. The presence of inhalation injury, elevated carboxyhemoglobin levels, and advancing age were significantly associated with larger burns. From the NBR data, most firefighter burn injuries were small, and few firefighter burn patients required critical care resources or had significant disability. Firefighters comprise a small number of burn center admissions each year, yet they are an important population to consider for burn prevention efforts.     

A descriptive summary of New Jersey's 1985 burn population

Data obtained from the New Jersey State Department of Health on the 1985 hospitalized patients with burns and data collected from the National Burn Victim Foundation's standard burn reporting form were analyzed to gather information about the epidemiology of burns. Children (0 to 4 years of age) continue to be the largest percentage of the 0- to 18-year-old age group who sustain burn injuries, and 67% of those injuries are sustained by children under the age of 5. Males accounted for 69% of the total burn population; 58% of admissions were white; 69% of patients were admitted for partial-thickness burns, and 31% were admitted for full-thickness burns; the largest primary payer was third-party payers; and 92% of patients with burns were discharged to home or self-care. Data were also analyzed by examination of selected age groups to determine individual needs of specific groups. An analysis of burn injuries reported to the National Burn Victim Foundation confirmed previous reports that the home is the most likely place for a burn injury to occur and that flame and scald injuries predominate; scald injuries comprise 50% of all sustained burns. Gasoline vapors accounted for 54% of burn injuries caused by flames. The data supported efforts to develop programs that address the needs of the urban child, the 17- to 19-year-old age groups, and the elderly. The information that was collected served to redefine objectives for burn prevention programs.     

Outpatient firefighter burn injuries: a 3-year review

Previously, our Burn Center at the New-York Presbyterian/Weill Cornell Medical Center reported a decline during a 10-year period in the number of firefighters requiring hospitalization for burn injuries, from 53 patients per year to 15 patients per year. Because the incidence of structural fires continued at a constant rate of 26,240 to 30,841 per year during this time, it was postulated that an improvement in protective gear accounted for the decrease in injuries. However, it also was possible that more firefighters were being treated on an outpatient basis. Therefore, our Burn Center's outpatient treatment of firefighter burn injuries was reviewed to determine the epidemiology of firefighter burn injuries. On the basis of this study, the overall incidence of burn injuries in firefighters has continued at a constant level. These findings, however, demonstrate that the extent of injury has decreased in this population and suggest that the protective gear used by firefighters has contributed to these findings. These injuries, although minor to moderate, preclude the use of personal protective equipment until the burns are completely healed and contribute to a delayed return to full-duty status. These findings are consistent with nationally reported findings.     

Outpatient management of the burn patient

Data from the National Burn Repository 2002 report indicate that most burns are minor and that 80%, to 90% of burn injuries can be treated on an outpatient basis. This article discusses the assessment and outpatient management of burn injuries, the role of specialized burn centers, and the reimbursement for outpatient burn care.     

Analysis of admissions and outcomes in verified and nonverified burn centers.

The American Burn Association instituted a burn center verification process to ensure optimal care for patients with burn injury. Limited data exist regarding differences in admissions and outcomes between verified (VC) and nonverified burn centers (NVC). The study purpose was to compare demographics, treatment, and outcomes of VC and NVC. The five VC were compared with the 12 NVC using data from California's discharge database for the year 2003. A total of 2867 patients were admitted to a burn center, 1645 to NVC (132/center), and 1222 (244/center) to VC. NVC admitted 1496 (91%) of their patients from local area and 118 (7%) from other acute care hospitals; in contrast, 948 (78%) of VC patients were local and 253 (21%) were transfers from other acute care hospitals. VCs admitted twice as many burns > or =80% total body surface area as NVC. VCs admitted more patients with face burns (18% VC vs 14% NVC, P < .001), had more patients on mechanical ventilation (12.4% VC vs 9.9% NVC P < .04), and performed fewer operations (61% VC vs 66% NVC, P < .006). Mortality rate was 3% in NVC and 4% in VC. During the study period verified centers in California admitted more patients per center and treated more severely injured patients than nonverified centers. Despite these differences, VC had mortality rates comparable to their nonverified counterparts. These findings support the need for additional studies evaluating the impact of verification on burn care.     

Gender differences in mortality following burn injury

Clinical and experimental studies have demonstrated higher mortality following nonthermal trauma among males compared with females. To date, few clinical retrospective studies have focused on gender differences in outcome following burn injury with respect to age. All patients admitted to the University of Alabama at Birmingham (UAB) Burn Center between January 1994 and December 2000 were selected for inclusion in the study. Gender differences in demographic, clinical, and outcome characteristics were compared. Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for the association between mortality and gender, both overall and stratified by age. Over the 7-year study period, 1229 males and 382 females were admitted to the UAB Burn Center, and mortality rates were 7.2% and 13.4%, respectively (P = 0.0002). Female patients were more likely to be older, of the black race, and in poorer health. In addition, females were more likely to suffer flame and scald burns. The association between mortality and gender was modified by age. Up to age 60, mortality rates among females were over twice that of males (OR 2.3, 95% Cl 1.4-3.8); however, no difference was noted among those 60 and older (OR 0.9, 95% Cl 0.5-1.6). These associations persisted following adjustment for potentially confounding variables. Causes and timing of death were similar for males and females. Women less than 60 years of age who sustain burn injuries have an increased risk of death compared with males. Differences in the natural history of nonthermal trauma and burn injury may provide insight regarding these divergent findings.     

Influence of injury characteristics and payer status on burn treatment location in Washington state.

The provision of optimal burn care is a resource-intensive endeavor. The American Burn Association has developed criteria to help guide the decision to refer a patient to a burn center for definitive injury care. The purpose of this study was to compare the patient and injury characteristics of patients admitted to the single verified burn center in Washington State with those treated at other facilities in the state. We performed a retrospective review of all patients admitted to a hospital with a burn injury in Washington State from 1987 to 2005 using the state's discharge database (Comprehensive Hospital Abstract Reporting System). Patient and injury factors of patients admitted to the state's single verified burn center or at other hospitals were compared. Multivariate poisson regression was used to calculate the relative risk of injury and patient factors that were significantly associated with admission to the verified burn center. From 1987 to 2005, a total of 16,531 patients were admitted to a Washington State hospital after burn injury. Of these patients, 8624 (52.2%) were treated definitively at the University of Washington Burn Center. Patients treated at this verified center had larger overall burn size (7.4% vs 4.5% TBSA, P < .001), higher percent full-thickness burn (4.3% vs 1.2%, P < .001), and higher rates of inhalation injury (2.3% vs 1.5%, P = .005). Uninsured status (relative risk = 1.46, 95% confidence interval = 1.4-1.5) was also significantly associated with treatment at the verified burn center. Injury severity and payer status were both found to be independent predictors of treatment at the single verified burn center in Washington.     

Cost-effective use of helicopters for the transportation of patients with burn injuries

We performed a retrospective review to analyze the use of helicopters for the transportation of patients with burn injuries to determine whether a more cost-effective approach could be developed without impairing the quality or delivery of health care. Charts were reviewed for all patients with burn injuries who were transported by helicopter to our hospitals during a 2-year period. Patients with inhalation injuries, with burn injuries received more than 24 hours before admission or more than 200 miles from our burn center, with more than 30% total body surface area (TBSA) burned, or with associated trauma injuries were excluded. Control patients with burn injuries who were transported by ambulance were identified and matched to the patients with burn injuries transported by helicopter for the percentage of TBSA burned, the percentage of third-degree burns, transport mileage, and age. The outcome was evaluated by comparison of length of stay, days on ventilator, and mortality rate. Comparisons were performed with Student t test. The transportation charge was determined for the patients transported by helicopter who we believed were eligible for transport by ambulance. Forty-seven of 85 patients transported by helicopter matched the inclusion criteria and had survived. There was no statistically significant difference between the percentage of TBSA burned, the percentage of third-degree burns, length of stay, days on ventilator, age, or transport mileage. There was, however, a significant difference in the time from the injury to admission to the hospital, as well as in the charge for transportation. Patients who had less than 30% TBSA thermal cutaneous injuries without evidence of inhalation injury, and who are less than 200 miles from a burn center may be safely transported by ambulance. Ambulance transportation may take additional time; however, stricter protocols for helicopter transportation of patients with burn injuries will result in potentially substantial savings without affecting outcomes for patients.     

Self-inflicted burns in Athens, Greece: a six-year retrospective study

Self-inflicted burns represent a major social and medical problem. The aim of this study was to record the epidemiology, mortality and etiology of suicide attempts by burning, in Athens, Greece. Over a 6-year period from April 1997 to April 2003, all the medical charts of the patients who were admitted to the Burn Center of the General State Hospital of Athens, Greece, with self-inflicted burns were retrospectively studied. Of the 1435 burn patients, 53 (3.69%) had attempted suicide by self-inflicted burn. Their ages ranged from 18 to 90 years old (mean 53.5 years). Females (57%) outnumbered males (43%). The mean total body surface area (TBSA) burned was 41.6% (range: 15-100%). The overall mortality rate was very high (75.4%). A preexisting psychiatric disorder was present in 43.3% of the patients. In conclusion, the extent and the depth of the burn injuries could explain the high mortality rate seen in these patients, in correlation with their negativism to the treatment. Burn care professionals should be familiar with self-inflicted burn patients who constitute a considerable proportion of major burns and require constant psychiatric support in addition to burn care.     

Occupation-related burn injuries

Unlike household burn injuries, the characteristics of burn injuries in the workplace have not been well described. In an effort to understand the causes and effects of occupation-related burn injuries and to aid in prevention, we sought to describe work-related burn injuries by frequency, burn type, age of the patients, body parts burned, and occupation of the patients. This was a statewide, cross-sectional study of all burns that occurred in the workplace during 1994. Data on fatal injuries were obtained from the National Census of Fatal Occupational Injuries. Survey data from the North Carolina Department of Labor were used for nonfatal injuries. Burns caused 34 deaths (15.3%) and 1720 injuries in the workplace in 1994. Of the nonfatal injuries, 1363 (79.2%) were caused by exposure to caustic substances or hot objects or substances. The head and upper extremities were the most frequently injured body parts (936 injuries; 57.6%). The average age of those burned was 30.7 years; most of the patients ranged from 25 to 35 years old. High-risk occupations included vehicle and equipment cleaners, food service personnel, and millwrights (11.3%, 5.3%, and 5.2% of burn injuries, respectively). Unlike the flame burns that occur in homes, exposure to caustics and hot objects and substances caused the majority of on-the-job burn injuries. Protective gear for the head and upper extremities may prevent a significant number of burns. Education and prevention programs may best be directed at workers with high-risk occupations and workers in the 25- to 35-year age range.     

Positive fungal cultures in burn patients: a multicenter review.

Fungal infections are increasingly common in burn patients. We performed this study to determine the incidence and outcomes of fungal cultures in acutely burned patients. Members of the American Burn Association's Multicenter Trials Group were asked to review patients admitted during 2002-2003 who developed one or more cultures positive for fungal organisms. Data on demographics, site(s), species and number of cultures, and presence of risk factors for fungal infections were collected. Patients were categorized as untreated (including prophylactic topical antifungals therapy), nonsystemic treatment (nonprophylactic topical antifungal therapy, surgery, removal of foreign bodies), or systemic treatment (enteral or parenteral therapy). Fifteen institutions reviewed 6918 patients, of whom 435 (6.3%) had positive fungal cultures. These patients had mean age of 33.2 +/- 23.6 years, burn size of 34.8 +/- 22.7%TBSA, and 38% had inhalation injuries. Organisms included Candida species (371 patients; 85%), yeast non-Candida (93 patients, 21%), Aspergillus (60 patients, 14%), other mold (39 patients, 9.0%), and others (6 patients, 1.4%). Systemically treated patients were older, had larger burns, more inhalation injuries, more risk factors, a higher incidence of multiple positive cultures, and significantly increased mortality (21.2%), compared with nonsystemic (mortality 5.0%) or untreated patients (mortality 7.8%). In multivariate analysis, increasing age and burn size, number of culture sites, and cultures positive for Aspergillus or other mold correlated with mortality. Positive fungal cultures occur frequently in patients with large burns. The low mortality for untreated patients suggests that appropriate clinical judgment was used in most treatment decisions. Nonetheless, indications for treatment of fungal isolates in burn patients remain unclear, and should be developed.     

Acute assessment and management of burn injuries

Burns are ubiquitous injuries in modern society, with virtually all adults having sustained a burn at some point in their lives. The skin is the largest organ of the body, basically functioning to protect self from non-self. Burn injury to the skin is painful, resource-intensive, and often associated with scarring, contracture formation, and long-term disability. Larger burns are associated with morbidity and mortality disproportionate to their initial appearance. Electrical and chemical burns are less common injuries but are often associated with significant morbidity.     

The effects of burn severity and institutional differences on the costs of care

Burn care treatment is among the costliest yet least studied forms of care. This paper presents estimates of the magnitude and components of burn care costs. It analyzes the extent to which burn care cost is determined by severity of burns or by characteristics of the institution in which the patient is treated, based on patient-specific data from eight hospitals representing different levels of technical sophistication in the delivery of burn care. Costs of care are higher in specialized facilities. Many patients with small burns are treated in specialized facilities, at much higher costs than patients treated in general care facilities. Among specialized facilities, patient severity accounts for a portion of the variance in costs, but significant cost differences remain after adjusting for severity. These results suggest that cost-control efforts should concentrate on specifying criteria for admission to specialized burn facilities, regional coordination of facilities and institutions, and improved facilities design and management.
