Abstract:
Objective To analyze the epidemiological characteristics of hospital admission cases with chemical poisoning in
Guangdong Province from 2016 to 2020. Methods Data of hospital admissions for chemical poisoning in Guangdong Province
from 2016 to 2020 were collected through Guangdong Province Health Statistics Network Reporting System，and descriptive
analysis was conducted. The seasonal characteristics of the number of hospitalized poisoning cases were analyzed by the
concentration method，the seasonal index（SI）was calculated by the weighted annual ratio averaging method，and the spatial
auto-correlation of regional poisoning trend was analyzed by the global and local spatial autocorrelation. Results From 2016 to
2020，the number of hospital admissions for chemical poisoning in Guangdong Province was 54 656，showing a general
decreasing trend. The sex ratio（male to female）was 0.90 ∶1.00. The top three types of hospitalization rates were carbon
monoxide poisoning，alcohol poisoning and organic solvent poisoning. The main poisoning groups were students and children，
farmers，workers and unemployed people，accounting for 31.74%，18.53%，13.91% and 10.39%，respectively. The 74.37% of
poisoning cases were cured or improved and discharged，and the case fatality rate was 0.48%. The top three hospitalization rates
in age group of 0-<5 years were organic solvent，metal and carbon monoxide poisoning. The hospitalization rate of carbon
monoxide poisoning ranked the first among all age groups of ≥5 years. The top three regions with the highest average annual
hospitalization rate were Shaoguan City （25.14/105
），Qingyuan City （17.04/105
） and Meizhou City （16.09/105
）. Carbon
monoxide poisoning had a strong seasonality（M=0.77），with high incidence months of January，February and December（SI
were 3.60，3.08 and 2.48，respectively）. The inpatients with chemical poisoning showed non-random distribution and spatial
correlation（all P<0.01），with a high-high clustering among 13 districts and counties in northern Guangdong（all P<0.05）.
Conclusion The number of hospital admission cases of chemical poisoning showed an overall decreasing trend in Guangdong
Province from 2016 to 2020. The main types of poisoning were carbon monoxide poisoning，alcohol poisoning and organic
solvent poisoning. The spatial distribution of chemical poisoning types showed spatial correlation and there were high-high
clustering areas.
