Wildfire smoke can have far-reaching effects on public health, as evidenced by a recent study conducted by the University of Maryland Institute for Health Computing (UM-IHC). The research found that smoke from Western Canadian wildfires in June 2023 led to a significant increase in medical visits for heart and lung problems on the East Coast of the United States, particularly in Baltimore and the surrounding region.
During the summer of 2023, a massive smoke plume originating from severe Canadian wildfires traveled 2000 miles across the country, causing poor air quality and health issues for residents on the East Coast. Dr. Mary Maldarelli, a pulmonary critical care fellow at the University of Maryland School of Medicine, noted that patients reported increased coughing and reliance on medications due to the smoke-filled air.
To quantify the health consequences of these smoke-filled days, researchers at UM-IHC analyzed satellite data and Environmental Protection Agency (EPA) data to identify six “hotspot” days with high levels of wildfire smoke-related air pollution in Maryland. Comparing medical visits for heart and lung conditions during these days with data from previous years, the study found an 18% increase in patients seeking medical care for cardiopulmonary issues.
Dr. Bradley Maron, Professor of Medicine at UMSOM and Co-Executive Director of UM-IHC, highlighted a 55% increase in outpatient visits for heart and lung conditions on hotspot days. This increase was particularly notable among older, non-smoking, and socio-economically affluent patients, indicating potential disparities in access to healthcare during high-risk air quality days.
Moving forward, the study suggests the importance of proactive identification and care for at-risk patients on days with poor air quality. Leveraging data analytics and telehealth services could help mitigate cardiovascular complications and ensure equitable access to medical care during future climate events.
The research team included experts from various institutions within the University of Maryland system, emphasizing the collaborative effort to address public health challenges posed by environmental factors like wildfire smoke. The study’s findings underscore the critical role of advanced analytical tools in shaping the future of healthcare and driving innovation in patient care.
