Investigation on status of patients with occupational pneumoconiosis in a district of Beijing City
Objective To understand the current situation of occupational pneumoconiosis patients in a district of Beijing City,provide scientific basis for the government and other departments to formulate pneumoconiosis protection and treatment policies.Methods All occupational pneumoconiosis patients reported in a district of Beijing City from 2001 to 2020 were selected,telephone follow-up was conducted to collect information.The descriptive analysis was performed on the age,gender,region,stage and type of pneumoconiosis,age of diagnosis,working years,industry,enterprise size,economic type,social security and comorbidities.Results By the end of 2020,a total of 132 cases were reported in a district of Beijing,including 54 cases(40.91％)of phage Ⅰ,36 cases(27.27％)of phage Ⅱ,and 42 cases(31.82％)of phage Ⅲ,silicosis(112 cases,84.85％)was the predominant.There was a statistically significant difference in stage between the genders(x2=6.217,P＜0.05),and there was no significant difference in the age of exposure to dust and the age at diagnosis among the patients at different stages(P＞0.05).Among 132 pneumoconiosis patients,130 cases were actually followed up,with the follow up rate of 98.48％,of which 112 cases(84.85％)survived and 18 cases(13.64％)died.Most of cases were female(89 cases,67.42％)and silicosis was the dominant type of pneumoconiosis(112 cases,84.85％).The median length of exposure[M(P25,P75)]was 12(8,16)years.The average age of diagnosis was(52.43±10.67)years old.41.96％(47 cases)of survival cases were in the age group of 45-＜55,96 cases(85.71％)were exposed to dust for 5-20 years,the age of diagnosis was mainly concentrated in 40-＜50 years old and 50-＜60 years old.Totally 111 survived cases had at least one social security,which were the basic medical insurance for urban and rural residents(109 cases,97.32％)and occupational injury insurance(30 cases,26.79％).Conclusion The risk of occupational pneumoconiosis is still high in a district of Beijing City,and it is necessary to effectively control the source and deal with the aftermath,and continue to strengthen the prevention and control of pneumoconiosis.
