Indoor Air Quality Asthma Study: The Effect of Indoor Air Quality and Mitigation of Same on Persistent Asthma (IAQ)

January 4, 2024 updated by: Daniel Evans, MD, Dayton Children's Hospital

Indoor Air Quality Asthma Study: A Cooperative Study Between Coepland LP, Cairify, and Dayton Children's Hospital to Determine the Effect of Indoor Air Quality and Mitigation of Indoor Air Quality on Persistent Asthma

The primary objective is to determine whether continuous sensing, control and mitigation of home indoor air quality influences the frequency of asthma related symptoms, as measured by Serum IgE, Spirometry with exhaled Nitric Oxide, missed school and workdays, need for pharmacologic intervention (albuterol, oral steroids), frequency of sick visits to pulmonologist or primary care provider (PCP), urgent care / emergency department visits, and hospitalizations

Detailed Description

Participants will be in the research study for approximately 2 years. There will be 11 visits to the clinic for monitoring of asthma symptoms and pulmonary function and 16 interval contacts with research staff made by either telephone or email to monitor asthma symptoms. There will also be 5 visits to participants' homes by technicians from Emerson Climate Technologies and/or an electrician in cooperation with Emerson. During these visits Emerson employees will assess participants' homes to determine if they qualify for the study and install study equipment to monitor air quality for the first half of the study and monitor and mitigate air quality for the second half of the study. At the end of the study, the technicians and/or electrician from Emerson will reset the study equipment or replace participants' original equipment, if that is their wish.

Participants will be enrolled in the research study for approximately 2 years. The first year, technicians from the study sponsor will install indoor air quality monitoring equipment in the participants' homes and information about the air quality in their home as well as baseline health and asthma information will be collected. This will be done through continuous sensing via an Atmocube air quality sensor, and a portable air quality sensor, the Atmotube. Beginning in the second half of the study, mitigation strategies of a smart home thermostat, the Sensi Touch Smart Thermostat, a smart bath fan control, the Enbrighten Z-wave Switch, and high quality furnace filter, 3M Filtrete MPR 2800 Ultrafine Particle Reduction Air Filter, will be employed. Information about the participants' asthma, health status, and air quality in the homes will continue to be collected.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Pre-mitigation
Information will be collected from participants about their health status and asthma symptoms. Information about the air quality inside the participants' homes will also be collected.
Experimental: Indoor Air Quality Mitigation
Indoor air quality mitigation strategies of a smart home thermostat, smart bath fan switch, and a high-quality furnace filter will be employed within the participants' homes. Information will continue to be collected about participants' health status and asthma symptoms as well as the air quality inside their homes.
Device: Indoor Air Quality Mitigation
