Epidemiology of pediatric burns in southwest China from 2011 to 2015

Abstract

Background: Burns are a major form of injury in children worldwide. This study aimed to investigate the epidemiology, outcome, cost and risk factors of pediatric burns in southwest China.

Methods: This retrospective study was performed at the Institute of Burn Research of the Third Military Medical University from 2011 to 2015. Data, including demographic, injury-related, and clinical data and patient outcome, were collected from medical records.

Results: A total of 2478 children with burns (58.03% boys), accounting for 39.2% of total burn patients, were included. The average age of the burn patients was 2.86±2.86years, and most patients (85.55%) were under five years old. The incidence of burns peaked in January, February and May. Scald burns were the most frequent (79.06%), followed by flame burns (14.0%) and electrical burns (3.35%). Limbs were the most common burn sites (69.73%), and the average total body surface area (TBSA) was 11.57±11.61%. The percentage of children who underwent operations and the number of operations were significantly increased in cases of electrical burns, the older-age group, a larger TBSA and full-thickness burns. Six deaths were recorded, yielding a mortality of 0.24%. The median length of stay and cost were 14days and 9541 CNY, respectively, and the major risk factors for length of stay and cost were the TBSA, number of operations, full-thickness burns and outcome.

Conclusions: In southwest China, among children under five years old, scald and flame burns should become the key prevention target, and future prevention strategies should be based on related risk factors.
