Characteristics of burn patients at a major burn center in Shanghai.

In China, burns are becoming a major cause of morbidity and mortality with large societal and economic implications. To date, there is little epidemiological data on burns in China to direct prevention efforts. This study describes the characteristics of burn patients admitted to a major burn center in Shanghai using a burn registry developed in Toronto, Canada. A retrospective review of burn patients discharged from the Shanghai's Rui Jin Hospital Burn Unit, between March 1st 2002 and April 30th 2003, was conducted. Of 527 patients discharged, 307 were acute burn patients and 302 (98.4%) had complete data to be included in the study. There were 214 (71%) males and 88 (29%) females with a male to female ratio of 2.4:1. The median age was 30 years, and the median total body surface area burned was 10%. The majority of burns occurred at work (58%), and the most frequent etiology was flames (39%) followed by scalds (31%) and contact with hot objects (15%). Sixteen (5%) patients had inhalation injury and six (2%) patients died. There were 70 (23%) children (0-14 years), 221 (73%) adults (15-59 years) and 11 (4%) seniors (60 years and above). Children had more scald burns (83%) and the majority (83%) occurred at home. Adults had more flame burns (46%) and the majority (79%) were work-related injuries. Seniors had more flame burns (73%) and the majority (55%) occurred in domestic incidents. Seniors had deeper burns (13%, p=0.005), required more escharotomies (55%, p=0.002), required more operations (2, p=0.051) and had higher mortality (36%, p<0.001) than other age groups. These results provide compelling evidence for performing population-based studies to identify risk factors that are susceptible to modification in each age group.
