Patients with chronic obstructive pulmonary disease (COPD) are relying on smartphone apps and online information rather than speaking with their doctor about the risks of wildfire smoke, according to a new study.
A new study in the May 2026 issue of Chronic Obstructive Pulmonary Diseases: Journal of the COPD Foundation has found that many individuals with COPD are not receiving reliable health information to protect themselves.
Wildfire smoke significantly degrades air quality across the United States and is a major contributor to pollution. It poses particular risks for people with COPD, often triggering breathing problems and exacerbations. COPD—which includes conditions such as emphysema and chronic bronchitis—affects over 30 million Americans and ranks as the fourth leading cause of death worldwide.
Patients had limited knowledge of mitigation strategies
The study involved interviews with people living with COPD who were enrolled in Kaiser Permanente Northern California and had experienced significant wildfire events nearby. The research aimed to understand participants’ knowledge of wildfire smoke, protective behaviors, and sources of information.
Findings showed that most participants rely on smartphone apps and online resources for air quality updates; many have not discussed the health impacts of air quality with their doctors; there is limited awareness of mitigation strategies such as indoor air purifiers or using the vehicle air recirculation function; and there is a preference for real-time guidance from healthcare providers during poor air quality events.
A ‘patient-centred’ approach to wildfire education is needed
“Some patients are already monitoring air quality but not all,” said Laura C. Myers, M.D., MPH, of Kaiser Permanente Northern California and senior author of the study. “We need to make sure that people with COPD receive accurate, actionable guidance from trusted sources in real-time so they can take actions to protect themselves. Patient-centered approaches to wildfire preparedness can help the most vulnerable people prepare for and respond to air quality events before their symptoms get worse.”
