Healthcare utilization of lung cancer patients associated with exposure to fine particulate matter: A Korean cohort study.

ABSTRACT:

Background

Higher concentrations of particulate matter (PM) have been shown to cause deterioration of the symptoms of respiratory and cardiovascular disease in several regional studies. Here, we aimed to investigate the healthcare utilization of lung cancer patients associated with short-term exposure to PM at the national level in Korea.

Methods

We extracted the data of 210 558 subjects over a period of 3 years (2015-2017), who were diagnosed with lung cancer before 2015 and benefited from the National Health Insurance Sharing Service. We performed the interpolation method using the geographic information system to calculate the estimated mean PM_2.5 and PM₁₀ concentrations by regions and classified three groups as high (upper 10%), intermediate (10%-90
