Patient outcomes concerning toxic epidermal necrolysis (TEN) have improved over the years as a better understanding of the pathophysiology of the illness has been gained and enhancements have been made in the care of the acutely ill. With increase in survival, long-term complications these patients experience are beginning to be recognized. In this study, we analyzed the outcomes of a cohort of TEN survivors treated at our burn unit and sought to determine the impact of clinical variables from the initial hospitalization on mortality after discharge. We performed a retrospective review of data from patients with TEN treated at our burn unit from March 1993 to September 2002. Follow-up data on new health problems were collected on patients who were alive at discharge via questionnaire. Survival was estimated using the Kaplan-Meier method with Cox regression model. During the study period, of the 64 patients treated for TEN, 46 survived. After discharge, 15 patients died, whereas the remaining 31 patients continued to suffer from ocular (54%), skin (81%), and renal (23%) problems. Median survival for the whole cohort has not been reached, with an estimated 5-year survival of 65%. No patient in either group had a TEN recurrence. Seventy-nine percent of the patients with ocular involvement in the acute phase of TEN had long-term ocular complications, and 73% of patients with mucosal involvement had persistent mucosal lesions. Five individual factors were found to be predictors of postdischarge mortality on univariate analysis: age at diagnosis of TEN>or=60 years, SCORTEN 3 to 6, % maximal TBSA slough>or=50%, days from onset of symptoms to admission to a burn unit>or=5 days, and presence of multiple comorbidities at diagnosis of TEN. In multivariate analysis, only SCORTEN of 3 to 6 (P=.003) and days to admission>or=5 (P=.027) maintained significance as predictors of mortality and may be used to heighten surveillance during postdischarge care of patients with TEN.

With longer life expectancy, the number of burn injuries in the elderly continues to increase. Prediction of outcomes for the elderly is complicated by preinjury physical fitness and comorbid illness. The authors hypothesize that admission frailty assessment would be predictive of outcomes in the elderly burn population. Our primary aim was to determine if higher frailty scores were associated with higher risk of mortality for elderly burn patients. The secondary aims were to assess if higher frailty scores were associated with increased length of stay, increased needs for mechanical ventilation and poor discharge disposition. A 2-year retrospective chart review was performed of all admitted acute burn patients 65 years or older. Data collected included: age, gender, %TBSA of burn injury, presence of inhalation injury, in hospital mortality, hospital length of stay, ventilator days, ICU length of stay, surgical procedures, insurance status, and discharge disposition. Frailty scores were assessed from admission data and calculated using the Canadian Study of Health and Aging clinical frailty scale. A total of 89 patients met entry criteria. Mean age was 75.3 ± 8.1 years and consisted of 62 men and 27 women. Mean %TBSA was 9.6 ± 9.1% and mean frailty score (FS) was 4.5 ± 1.2. Eighty patients survived to discharge and nine died. Nonsurvivors had significantly higher FS compared to survivors (5.2 ± 1.2 vs 4.4 ± 1.2). FS were also significantly higher in patients discharged to skilled nursing facilities (SNF) (5.34 ± 0.9) compared to those who were discharged home (4.1 ± 1.2) or to physical rehabilitation facilities (4 ± 1.5). Multivariate linear regression analysis revealed that age (B = 0.04) and discharge to SNF (B = 1.2) are independently associated with higher FS. However, survivors were independently associated with a significantly lower FS (B = -1.3). Multivariate logistic regression analysis revealed high admission FS independently increased the risk of discharge to SNF (odds ratio of 2.5 [1.3-4.8, 95% confidence interval]) and increased the risk of mortality (odds ratio of 1.67 [1.01-2.7, 95% confidence interval]). Frailty scores on admission allow for a more complete assessment of elderly patients and can be used to establish benchmark models for burn injury outcomes. In addition FS can be used as a research tool to improve outcomes for elderly burn injured patients.

Advanced Burn Life Support emphasizes endotracheal intubation for patients with facial burns before transfer to a burn center to prevent airway obstruction. Many patients are intubated before transport and are often extubated shortly after burn center arrival. We hypothesize that many intubations performed before burn center transport are unnecessary. We conducted a retrospective review of all adults who were intubated before burn transfer and survived to discharge from August 2003 to June 2013. Intubations that had 2 or fewer ventilator days (i.e., potentially unnecessary intubations) were compared with those lasting longer than 2 days. Data collected included age, ventilator days, length of stay, % TBSA burn, % second degree, % third degree, % second degree face burn, % third degree face burn, and origin of burns. A total of 416 patient met inclusion criteria. Of these, 129 patients (31.0%) were intubated less than or equal to 1 day, and a total of 171 (40.1%) patients remained intubated for less than or equal to 2 days. Patients who were intubated less than or equal to 2 days differed from those intubated more than 2 days with respect to % TBSA burn (10.2 ± 8.1 vs 30.8 ± 19.7, P < .001), % third degree burn (2.84 ± 5.6 vs 22.5 ± 19.6, P < .001), % third degree face burn (0.14 ± 0.7 vs 0.94 ± 1.9, P < .001), and hospital days (11.7 ± 10.6 vs 50.7 ± 43.7, P < .001). Additionally, patients who were intubated less than or equal to 2 days were more likely to have been intubated in the pre-burn center setting (74.9% vs 51.8%, P < .001) and to have been burned outdoors (42.1% vs 24.9%; P < .001) than those who were intubated more than 2 days. Multivariate analysis revealed that intubation longer than 2 days was independently associated with older age and larger % TBSA burn. There were no reintubations in patients who were intubated 2 days or less. As a burn community, we have emphasized early intubation before transfer for those who have sustained significant burns, inhalational injury, or facial burns. Unfortunately, this has led to many potentially unnecessary intubations that expose patients to unnecessary complications. Although early intubation is a lifesaving intervention for many burn patients, criteria should be developed to determine when intubation is not needed.
