Abstract

The World Health Organization has defined 'elderly' as 65 years or older. Age is a known major prognostic factor after burn injury. The objective of this study is to establish whether epidemiologic differences in the elderly contribute to higher mortality compared to younger patients. Patients admitted to the burn unit between 2011 and 2014 (229 patients) were included: 159 were under 65 years old and 70 (30.6%) were 65 or over. The elderly group had a higher mortality rate, 24.6% versus 8.2% (p=0.002). Patients over 65 presented more pre-existing co-morbidities (1.7 ± 1.1) than patients under 65 (1.1 ± 1.0), p<0.001, and COPD was significantly associated with higher mortality rate (p=0.014). Patients over and under 65 suffered similar TBSA, 15.7 versus 14.1, p=0.720. Regarding burn depth, deeper burns were significantly more prevalent in the over 65 group (17.1% vs. 5.0%, p=0.003). Patients over 65 developed more complications (0.9 ± 1.1) than the under 65s (0.5 ± 0.9), p=0.009, and sepsis was significantly associated with higher mortality rate (p=0.042). Over-65-year-old burn victims have a higher mortality risk than the under 65s. Elderly patients generally have more pre-existing comorbidities and develop more complications during hospital stay, which increase the mortality risk. Apparently, history of COPD or sepsis complication during hospital stay are independent risk factors for death in the elderly group. Although over-65-year-olds presented similar TBSA to the younger patients, the proportion of deep burns was higher, which suggests that burns might be more aggressive in the elderly.
