B44-48 Wildfire Preparedness for Patients With COPD and Asthma

Abstract Introduction Wildfires have increased in frequency with climate and environmental changes. Individuals with chronic lung diseases—chronic obstructive pulmonary disease (COPD) and asthma—are among the most vulnerable to the impact of wildfire smoke, especially the poor air quality. Recognizing this as a significant environmental threat to our patients. We sought to assess wildfire preparedness in our population and identify potential targets for intervention among individuals with chronic respiratory disease. Methods We performed a survey of primary care patients diagnosed with COPD or asthma at UC Davis Health via an online platform assessing wildfire preparedness, symptom burden, and protective behaviors. Data were analyzed using descriptive statistics. Results Of 1,913 patients invited, 166 consented to participate (response rate: 8.7%). Participants were 69% female and 75% Caucasian, with a mean age of 66 ± 15 years (range 21-91). Twenty-one percent lived in areas with a Healthy Places Index of 50% or less. Most respondents (64%) were very or extremely concerned about the health effects of wildfire smoke. Over the prior 12 months, participants reported symptoms related to wildfire smoke exposure, including cough (52%), shortness of breath (40%), and headache (31%), while only 35% reported no symptoms. Despite the high symptom burden, only 51% reported having a COPD/asthma action plan for worsening respiratory symptoms. In the past year, 45% contacted a healthcare professional at least once for breathing problems. Most participants (79%) knew how to check their local air quality index (AQI). Common protective behaviors included staying indoors (69%), using air filters (49%), and reducing outdoor activity (58%). However, 69% did not have an emergency “go bag” containing medications or respiratory equipment for potential evacuation. Poor air quality led to difficulty obtaining medications (11%) and attending medical visits (11%). Notably, 90% of participants rated wildfire smoke preparedness education as moderately to extremely helpful for managing their respiratory condition. Conclusions Survey findings from patients with COPD and/or asthma highlight significant gaps in wildfire preparedness despite high levels of concern and symptom burden. Actionable opportunities include improving access to COPD/asthma action plans, educating patients on assembling emergency “go bags,” and ensuring continuity of medication access and healthcare during poor air quality events. Implementing these interventions could meaningfully improve wildfire readiness among this vulnerable population. A post-educational intervention survey is planned. This abstract is funded by: None
