Objective To analyze the epidemiological characteristics of injury inpatients in Guangzhou, Guangdong province, and provide information for injury prevention and control.
Methods The records of inpatient diagnosed with injury from 2018 to 2020 were collected from 5 surveillance sentinel hospitals in Guangzhou. A descriptive epidemiological analysis was conducted on time distribution of injury, injury type and hospitalization cost and length by using Excel 2016 and software SPSS 22.0.
Results A total of 18 978 cases of injury were investigated in hospitals, in which 11 794 cases were men (62.15%), the male to female ratio of the cases was at 1.64∶1. The injury cases in people aged ＞60 years (5 745 cases) accounted for highest proportion (30.27%) in total. The top three types of injuries were fall (6 957 cases, 36.66%), traffic accident (3 310 cases, 17.44%) and fire hazard and burn injury (3 235 cases, 17.05%). Injury mainly occurred in July, followed by January-April. Fire hazard and burn injury had the longest length of hospital stay for treatment ［12 (8, 20) days］ and highest healthcare costs per case ［18209.06 (9332.41, 36711.7) yuan RMB］, followed by those of fall ［10 (6, 16) days］, ［15399.55 (6355.96, 37986.53) yuan RMB］.
Conclusion The disease burden of injury is heavy in Guangzhou. It is necessary to carry out targeted health education and intervention based on the characteristics of injury.
