Impacts of event-specific air quality improvements on total hospital admissions and reduced systemic inflammation in COPD patients.

ABSTRACT: There is limited evidence linking the impacts of reduced air pollution on hospital admissions. The potential biological mechanisms are still not completely understood. This study examined the effects of mitigated ambient pollution on hospital admissions and inflammatory biomarker levels in chronic obstructive pulmonary disease (COPD) COPD patients. Daily hospital admissions were compared over 51 days associated with the Asian Games period (Nov 1-Dec 21, 2010) with the identical calendar dates of baseline years (2004-2009 and 2011-2013). A three-year cohort study was conducted with 36 COPD patient participants. The daily particulate matter (PM10) decreased from 65.86 μg/m3 during the baseline period to 62.63 μg/m3 during the Asian Games period; the daily NO2 level decreased from 51.33 μg/m3
