ORLANDO – Use of an app combining patient-reported symptoms with local environmental triggers led patients to take action to improve their health, Penny Jones, PhD, reported at the joint congress of the American Academy of Allergy, Asthma, and Immunology and the World Asthma Organization.
AirRater is a smartphone app and data collection network that includes information on air particulates, daily pollen and fungi counts, temperature, and planned burn locations. Patients enter their respiratory symptoms, which are correlated with local environmental conditions, according to Dr. Jones, a postdoctoral fellow at the University of Tasmania (Australia) in Hobart.
Most of the environmental data are gathered from government agencies; however, researchers collect pollen and fungi counts at their own stations.
Patients do not see the environmental data until they’ve logged in their symptoms so that their reports aren’t biased by that information, Dr. Jones said, adding that the app also sends notifications when pollen and pollutant levels are high.
“It’s an environmental monitoring system coupled with a smartphone app designed to help people with allergies and asthma make better decisions around their health,” Dr. Jones said.
The AirRater network and app are now operating in both Tasmania and Canberra, Australia.
There are more than 6,000 users, and data from surveys show that it is having an effect, Dr. Jones said. About 40% of users said they have changed their behavior in some way because of information provided by the app, including staying indoors, taking preventive medication, or speaking with their doctors.“It does appear that people are generally finding it a useful tool,” she said.
In a pilot study, researchers found that several environmental triggers were significantly correlated with exacerbation of patient symptoms, including maximum temperature (P < .001), particulate pollution (P < .001), relative humidity (P = .01), birch pollen (P = .006), and cypress pollen (P = .004).
Researchers plan to expand use of the network and app to other parts of Australia and are working to refine the understanding of aerobiological symptom drivers through DNA analysis of airborne particles. Their goal is to be able to identify personalized drivers of sensitivities, she said.
“We’ll keep working on this,” Dr. Jones said. “But we think that certainly has promise.”
The investigators reported no financial conflicts of interest, and the study had no outside funding.
