Abstract:
Objective To evaluate the impact of particulate matter (PM) pollution on the hospitalization for respiratory diseases (RD), to estimate the avoidable economic loss by reducing the level of PM pollution, and to provide a basis for evaluating the cost-effectiveness of air pollution control. Methods The data of RD inpatients in two class-A tertiary hospitals in Wuhan from 2015 to 2019, PM concentration and meteorological data in Wuhan in the same period were collected. The generalized additive model (GAM) was used to estimate the impact of PM on the number of RD inpatients, and the cost of illness approach (COI) was used to estimate the avoidable economic loss caused by the reduction of PM concentration. Results PM pollution caused an increase in the number of RD inpatients. Each 10 g/m3 increase in PM2.5 and PM10 concentrations resulted in an increase of 1.71% and 0.71% in the number of RD inpatients, respectively. Among them, men and children aged 0-14 years were more affected. For every 10 g/m3 increase in PM2.5 concentration, the number of hospitalized men and children aged 0-14 years increased by 1.97% and 2.65%, respectively. For every 10 g/m3 increase in PM10 concentration, the number of hospitalized men and children aged 0-14 years increased by 0.87% and 0.88%, respectively. PM pollution caused 63 300 hospitalizations and 1.214 billion yuan of economic losses in 2015-2019,Wuhan. If the PM concentration is reduced to the recommended value of the World Health Organization in the same period, 194 million yuan of economic loss and 10100 hospitalizations could be avoided every year in Wuhan. Conclusion PM exposure can lead to heavy disease burden and economic loss. Taking effective measures to control PM concentration will bring great economic benefits.
