Doctor visits spike in Baltimore as Canadian wildfire smoke engulfs the city

Highlights
  • In June 2023, Baltimore experienced a spike in doctor visits due to wildfire smoke from Canada.
  • Researchers noted an 18 percent increase in cardiopulmonary visits on days with high levels of smoke-related pollution.
  • The findings suggest that wealthier patients were more likely to seek care during these high-risk pollution days.
Story

In June 2023, Canada faced its worst wildfire season on record, resulting in extensive smoke that impacted air quality across North America. Research conducted by the University of Maryland revealed a notable increase in medical visits related to heart and lung issues in Baltimore, located thousands of kilometers away from the wildfires. Researchers identified six specific days in June when pollution levels from the wildfire smoke were particularly high. On these ‘hotspot’ days, the likelihood of patients visiting doctors due to cardiopulmonary conditions increased by nearly 20 percent compared to similar days in June of prior years, 2018 and 2019. The study utilized anonymized data from hospital admissions and emergency department visits, demonstrating a quantifiable link between the smoke and health problems in a region not directly affected by the fires. Significantly, the study, published in Jama Network Open, indicates that the patients visiting doctors on high pollution days tended to be more affluent compared to those who sought care on days with better air quality. This discrepancy raises concerns about health disparities, suggesting that lower-income individuals may not be receiving adequate medical care during episodes of poor air quality. The fine-particle pollution originating from the wildfires is capable of penetrating deeply into the lungs, contributing to significant health repercussions, including exacerbation of chronic respiratory and cardiovascular conditions. As the climate crisis intensifies, events like these serve to highlight the far-reaching consequences of environmental changes, particularly regarding public health. Researchers advocate for increased awareness and preparedness for health impacts linked to air quality, particularly from wildfire smoke, which may affect urban populations distanced from the fire’s immediate impact. Given the complexity of the air pollution problem, there is an urgent need for policies aimed at mitigating emissions and protecting vulnerable communities well beyond the geographical boundaries of wildfire events.
