BACKGROUND
The mortality rate following burn is an important outcome parameter. This study aimed to identify factors associated with mortality in adult hospitalized burn patients in Tehran, Iran.
METHODS
This cross-sectional study was performed during a one-year period in two referral burn centers in Tehran. During the study period, 1321 adult (>15 years) hospitalized burn patients were enrolled. Univariate and multivariate (logistic regression) analyses were performed to identify factors associated with mortality.
RESULTS
The mean age of the patients was 33.1±14.9 years. By far, the majority of burns were accidental (n=1076, 81.5%). Regarding the mechanism of burn, burn with petroleum products was the most frequent. Mean percent burned total body surface area (TBSA) was 39.9%±25.8%. The mortality rate was 33%. Sepsis was the most common cause of mortality. The results of the present study indicated that non work-related burns, burned TBSA and body surface area affected by second- or third-degree burns were independent determinants of mortality among adult hospitalized burn patients.
CONCLUSION
The present study showed a high mortality rate in the studied burn centers. Patients with identified risk factors should be categorized as high risk at the time of admission and need special attention and care during hospitalization.

Keywords: Burn, Iran, mortality; risk factor; total body surface area.

AMAÇ
Yanýðý takiben ortaya çýkan mortalite oraný, önemli bir sonuç parametresidir. Bu çalýþmada, Tahran’da hastaneye yatýrýlan eriþkin yanýklý hastalarda mortalite ile birlikte olan faktörlerin belirlenmesi amaçlandý.
GEREÇ VE YÖNTEM
Bu çapraz karþýlaþtýrmalý çalýþma, Tahran’daki iki yanýk baþvuru merkezinde bir yýllýk periyotta yapýldý. Çalýþma periyodunda hastaneye yatýrýlan 1321 eriþkin (>15 yaþ) yanýklý hasta çalýþmaya kaydedildi. Mortalite ile birlikte olan faktörleri belirlemek üzere, tek deðiþkenli analiz ve çok deðiþkenli (lojistik regresyon) analiz yapýldý.
BULGULAR
Hastalarýn ortalama yaþý 33,1±14,9 yýl idi. Yanýklarýn büyük çoðunluðu kazaya baðlýydý (n=1076, %81,5). Yanýk mekanizmasý ile ilgili olarak, petrol ürünleri ile en sýk yanýk nedeni idi. Ortalama yüzde yanýk toplam vücut yüzey alaný (TVYA) %39,9±%25,8 idi. Mortalite oraný %33 oldu. Sepsis, en sýk mortalite nedeniydi. Bu çalýþmanýn sonuçlarýna göre eriþkin yanýk hastalarýnda iþ kazasý olmayan yanýklar, yanýk olan TVYA ve ikinci ve üçüncü derece yanýktan etkilenmiþ yüzey alaný mortalitenin baðýmsýz belirleycileridir.
SONUÇ
Bu çalýþma, çalýþýlan yanýk merkezlerinde yüksek bir mortalite oraný olduðunu göstermiþtir. Belirlenen risk faktörleri olan hastalar, yatýþlarý sýrasýnda yüksek riskli hastalar olarak sýnýflandýrýlmalý ve bu hastalara hastanede kalýþ süresince özel ilgi ve bakým gösterilmelidir.

Anahtar Kelimeler: Yanýk, Ýran, mortalite, risk faktörü; toplam vücut yüzey alaný.
