Epidemiological study of burn patients hospitalised at a burns centre, Manipal.

Burn injuries constitute a major public health problem and account for a significant cause of mortality and morbidity amongst the Indian population. This 2-year prospective study was undertaken to find out the exact epidemiological determinants of 737 patients admitted with burn injuries and, thus, to try and formulate effective preventive strategies. This study was conducted in the department of plastic surgery and burns from September 2011 to June 2013. All consecutive patients with major burns admitted for in-hospital treatment during the study period were included in the study. The data collected included age, gender, cause and mode of burns, total burn surface area (TBSA), microbiological profile and outcome. More than 55% of the patients were female (58.61%). The mean age was 31.3 years ranging from 8 months to 89 years. A higher number of females (97.5%) sustained burn injuries at home compared with 36.11% males sustaining injuries outdoors. (P = 0.000). Almost one third of injuries (40.36%) occurred between 4 pm and 8 pm, followed by 28% between 7 am and 12 noon. Synthetic garments were worn by 70% of females at the time of injury, whereas 40% of males had worn mixed clothing (P = 0.000). Flame injuries contributed to 80.1% of burns in females (P = 0.006). The rate of electrical injuries (9.8%) was significantly higher in males (P = 0.005). In almost 40% of males, TBSA was <19%, whereas in 40% of females, TBSA was >68%. (P = 0.004). Microbial profile showed that pseudomonas aeruginosa (n = 260; 35.3%), Klebsiella pneumoniae (n = 209; 28.5%), and Escherichia coli (n = 145; 22.6%) were the most frequent types of Staphylococci bacterial growths. The cause for burn injury was ignition of clothes in 68.74% females, and in 35.48% males, it was because of an attempt to save other burn injury victims (P = 0.013) The case fatality rate was 29.3%. A majority of the males (60.7%) recovered, whereas 45.89% of females succumbed because of their burn injury. (P = 0.001). As the aetiological factors of burn injuries vary considerably in different communities, careful study of the pattern in every community is needed before a sound prevention programme can be planned and implemented. Hence, this study was conducted to assess epidemiological, modes, causes, and risk factors and the microbial profile of burn injuries and to study the outcomes.
