Analysis of External Causes of Injuries and Poisoning Among 14,611 Hospitalized Cases in a Hospital in Guangzhou
Objectives This study aims to provide important basis for relevant local departments to formulate prevention and control measures by discussing the external causes of injury and poisoning and their occurrence patterns.Methods According to the classification principles of the International Statistical Classification of Diseases and Related Health Problems ICD-10,among all 76,785 medical records discharged from a hospital in Guangzhou from January 1,2019 to December 31,2022,a total of 14,611 inpatient medical records with the main diagnosis code S00-T98 and external cause code V01-Y89(excluding Y90-Y98)were retrieved.The external causes of injury and poisoning were classified according to ICD-10 coding categories,and Excel software was used to conduct data statistics according to frequency and composition ratio.Chi-square test was used for the enumeration data,and differences at P＜0.05 were statistically significant.Results Between January 1,2019,and December 31,2022,there were a total of 76,785 hospitalized cases,with 14,611 cases admitted due to injury poisoning(excluding Y90-Y98),representing 19.0％of the total discharges.The majority of these cases were permanent residents of the city(82.1％).The proportion of injury poisoning cases reached a minimum of 17.31％in 2020,increasing to over 19％in the remaining three years.The difference between male and female injury and poisoning cases across various age groups was statistically significant(x2=2021.49,P＜0.001),with the highest percentage(41.9％)observed among the elderly aged 65 years or older.Overall,the proportion of females was higher than that of males,with a ratio of 1.3 to 1.The top three external causes of injury and poisoning were falls(W00-W19)71.5％,overworked travel and poverty(X50-X57)10.7％,and transportation accidents(V01-V99)6.4％.Conclusions In the past four years,the number of injury and poisoning cases in the region has remained high.We should prioritize the elderly population aged over 65 and females,and implement preventive and control measures targeting the three primary external causes of injury and poisoning:falls,over-exertion during travel,poverty-related incidents,and transportation accidents.
