Abstract:

Objective To describe injury spectrum and economic burden of injury in Guangdong, and provide information for policy making. Methods Nonfatal survey was conducted by using 4 phase stratified cluster random sampling method and 3 counties were selected respectively from the big city, small city, Class I rural and Class II rural area. Thirteen survey points were selected for fatal injury survey using the proportional stratified cluster random sampling method. According to the census of 2000 in Guangdong Province, the ratios of deaths to the inpatient treatment, clinic treatment, and treatment by self/others or no treatment were calculated respectively, to draw the spectrum diagram. The fatal and nonfatal survey data were used to measure and calculate the economic burden of injury. Results A total of 18 505 individuals were investigated and 4 046 were found with the nonfatal damage. The incidence rate was 21.9% and the standardized rate was 21. 2%. Of them, there were 1 647 people with 17.7%(1 647/9 294 ) damage rate in the city and 2 459 people with 26.7%(2 459/9 210 ) damage rate in the rural area; 2 228 male people with 23.9% (2 228/9 324 ) damage rate and 1 818 female people with 19.8%(1 818/ 9 168 ) damage rate; 2 156 people between 0-19 years old with 28.4% damage rate, 1 432 people between 20 to 59 years old with 17.0% damage rate, and 458 people at 60 years old and above with 19.2% damage rate. The ratios of injury deaths to hospital treatment, clinic treatment, treatment by self / others or no treatment in Guangdong Province was 1∶[KG-*2] 27∶[KG-*2]126∶[KG-*2]472; the urban injury spectrum ratio was close to the rural one, but rural injury rate (26.7%) was higher than city’s（17.7%）; the female injury spectrum ratio （1∶[KG-*2]35∶[KG-*2]149∶[KG-*2]651）was higher than men’s（1∶[KG-*2]23∶[KG-*2]115∶[KG-*2]382）. The ratios of deaths to the inpatient treatment, clinic treatment, and treatment by self/others or no treatment decreased with the age increasing. 7 721 injury death cases were retrospectively investigated for the death-cause, the injury mortality was 50.7/100 000, and the standardized rate was 47.8/100 000. It is expected that would be 38 000 injury death cases per year and 1.173 million years of potential life lost (YPLL) in Guangdong. The YPLL in urban area, rural area, male, and female were 489 000, 684 000, 789 000, and 384 000, respectively. The medical cost for outpatient and hospitalization of the top 7 nonfatal injuries need 6.3 billion Yuan, including 5.2 billion Yuan for hospitalization and 1.1 billion Yuan for outpatient treatment. Conclusion The injury spectra were different in different regions, genders, age groups in Guangdong Province. The burden of injury was huge. It is urgent to mobilize resources and strengthen control and prevention of the injury.
