About this study

This pilot study (n=20) is a prospective evaluation of the implementation of an indoor air pollution intervention among adults 55 years of age or older. The intervention, called Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education (AIRWISE), is focused on improving indoor air quality through air filtration, education, and behavioral recommendations. All participants will receive the AIRWISE intervention with the objective of evaluating acceptance and use of the individual intervention components. This implementation study will inform the submission of a larger NIH proposal for a randomized trial. The central study hypothesis is that an intervention program with educational strategies and visual behavioral cues will increase knowledge and awareness of air pollution exposures among the participants and lead to improved intervention compliance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AIRWISEOther

    AIRWISE (Air Improvement and Real-time Monitoring for Wellness through Interactive Strategies and Education) utilizes personal air cleaners (PACs) to filter indoor air, while enhanced aspects focus on improving compliance to PAC use. Key components include low-cost sensors (PurpleAir, Inc, USA) that change color according to air quality index (AQI) and behavioral recommendations that correspond to varying AQI levels.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluate the implementation of an indoor air pollution intervention.

    As an implementation study, the investigators will administer the AIRWISE intervention to 20 adult participants (55+ years of age) and evaluate intervention fidelity, acceptance, and compliance over a 6-month period spanning the 2024 wildfire season. An important outcome measure is to understand how frequently participants use the primary intervention components that include personal air cleaners (PACs), an indoor air quality monitor that changes color based on air quality index, and educational materials. These 3 components will be evaluated via electronic surveys administered every 2 weeks over the course of the study. The investigators will use 7 Likert Scale (ordinal) questions to measure frequency of use for the intervention components. The 7 questions will be combined into a composite score of intervention use that ranges from 7 to 39, with higher scores indicating higher intervention use.

    Measured: 6 months

Secondary outcomes (2)
  1. Fine particulate matter (PM2.5)

    Measure indoor PM2.5 concentrations among participant households during intervention evaluation.

    Measured: 6 months

  2. Life's Essential 8

    The investigators will prospectively collect health measures to calculate a metric called Life's Essential 8 (LE8), a construct of cardiovascular health including blood pressure, lipids, glucose, body mass index, nicotine exposure, diet, physical activity, and sleep health. LE8 ranges from 0 to 100, with the score calculated as an unweighted average of the 8 component metric scores. Overall scores of 80 to 100 are considered high, 50 to 79 considered moderate, and 0 to 49 considered low. The investigators will then assess associations between the LE8 metric and indoor PM2.5 concentrations measured using the AIRWISE sensors. The hypothesis is that higher indoor PM2.5 concentrations over the course of the study will be associated with lower LE8 scores.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing AIRWISE in people with Coronary Heart Disease and Cardiovascular Diseases, run by University of Montana at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate the implementation of an indoor air pollution intervention. (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Nov 2025.
