2018--2022年北京市非职业性一氧化碳中毒事件的流行病学特征分析.

Objective To understand the epidemiological characteristics of non-occupational carbon monoxide poisoning incidents in Beijing from 2018 to 2022, and to explore targeted prevention and control measures. Methods The data were from the National Public Health Emergency Reporting Management Information System. Descriptive epidemiological methods were used to analyze non-occupational carbon monoxide poisoning incidents in Beijing from 2018 to 2022. Relative risk (RR) was used to assess the risk of morbidity and mortality. Results From 2018 to 2022, a total of 1841 non-occupational carbon monoxide poisoning incidents were reported in Beijing, with 2729 cases of poisoning and 31 deaths. The annual morbidity and mortality were 25.14 and 0.29 cases per million, respectively. There were two peaks of poisoning cases in spring and winter, accounting for 49.98% and 24.00% of the total cases, respectively. The highest incidence occurred between 8 and 11 o 'clock, accounting for 22.83%. In the inner suburbs, outer suburbs and urban areas, the incidence of non-occupational carbon monoxide was 0.96 cases/100 000, 1.27 cases/100 000 and 18.79 cases/100 000, and the mortality was 0.02 cases/100 000, 0.02 cases/100 000 and 0.11 cases/100 000, respectively. The poisoning incidents mainly occurred in residential families in 1633 cases, accounting for 88.70%; This was followed by 118 restaurants, accounting for 6.41 percent. The proportion of household poisoning incidents decreased from 92.10% in 2018 to 84.13% in 2022. The proportion of poisoning incidents in restaurants increased year by year from 4.23% in 2018 to 10.05% in 2022. The proportion of poisoning cases occurring at home decreased from 86.39% in 2018 to 71.84% in 2022. The proportion of poisoning cases in restaurants increased from 9.88% in 2018 to 20.57% in 2022. Conclusion The incidence and death risk of non-occupational carbon monoxide poisoning in Beijing is not balanced among regions, and the proportion of poisoning incidents in restaurants is increasing year by year. Targeted measures should be taken to strengthen the prevention and control work in the outer suburbs and key restaurants. [ABSTRACT FROM AUTHOR]
