How Do Air Pollution Alerts Affect Public Health Use?


Effects of an air pollution personal alert system on health service usage in a high-risk general population: a quasi-experimental study using linked data (7 page pdf, R A Lyons, S E Rodgers, S Thomas, R Bailey, H Brunt, D Thayer, J Bidmead, B A Evans, P Harold, M Hooper, H Snooks, J Epidemiol Community Health,  May 23, 2016)

Today we review an analysis of the reaction of an “intervention”  group of patients with air pollution- related illnesses (cardio-respiratory and COPD) to alerts produced by the UK’s airAware alert system over a two year period, as measured by visits to hospital emergency departments, compared to a control group which were not similarly afflicted. Results indicate a doubling of emergency admissions and four times the number of respiratory conditions for the intervention group compared to the control group. The authors conclude that some health interventions or alerts beyond a certain distribution level are harmful in terms of health service utilisation.
