DRIIVE (Data and Research on Interventions to Improve the Vehicular Environment)
Study Details
Study Description
Brief Summary
The purpose of this study is to look at air quality in cabs and see if the air quality inside taxi cabs is connected to increased risks for lung and heart health problems. Another purpose of the study is to see if putting an air filter inside the car may help improve the air quality and lower health risks.
This is important because air pollution can be harmful to health. Air pollution is made up of very tiny particles (things) floating in the air around us, called particulate matter. Particulate matter is made up of dust, smoke, dirt, and gas fumes and can get into our bodies as we breathe. It has been linked to risk for lung cancer and heart disease. It is important because taxi drivers spend many hours of their day inside their cars.
The investigators hope that this study will help them find out if using air filters inside cabs will help lower the levels of pollution in cabs and reduce its effects on the health of taxi drivers. They will use these results to educate the taxi driver community.

Detailed Description
DRIIVE (Data and Research on Interventions to Improve the Vehicular Environment) is a community-engaged translational pilot project that will utilize a three parallel arm design to obtain preliminary data on associations between Particulate Matter (PM)/air pollution and physiologic measurements and biomarkers in taxi drivers, and to determine the impact of a HEPA filter (to remove PM and volatile organic compounds) intervention on such physiologic measurements and biomarkers. DRIIVE is funded by the New York State Department of Health Empire Clinical Research Investigator Program (ECRIP), which trains physicians in clinical research in New York. Drivers will be randomized to one of two groups: Intervention or
Wait-list Control. In total, two groups of 14 participants in each group will be recruited:
- Wait List Control group, who will receive a HEPA filter at the end of the 1 month participation period, and 2) Intervention group, who will receive a HEPA filter two weeks into their participation period. The project will be completed within a 2 year timeframe.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Intervention Group During the first 2 weeks, measurements (e.g. biological markers and air monitoring) will be taken under usual conditions. At the end of the initial two weeks, portable HEPA air purifiers (136) will be placed in the Intervention Group drivers' cars and the air monitoring and biological parameters will be repeated for another 2-week period, to determine changes in PM levels and physiological measurements as a result of this targeted intervention. |
Device: HEPA air purifier
air purifiers to remove PM and volatile organic compounds will be placed in drivers cars
Behavioral: questionnaires
Other: Log-book
PM and biological measurements
Other: Urine sample
PAH (Polycyclic Aromatic Hydrocarbon) will be assessed via urine sample collection of Urinary 1 hydroxy pyrene and particulate matter collected via Polyurethane Foam Filter (PUF) sampler

Experimental: Wait-list Control Group During the first 2 weeks, measurements (e.g. biological markers and air monitoring) will be taken under usual conditions. The Wait-list Control Group drivers will not receive a HEPA air purifier at this time, but will also have the air monitoring and biological parameters repeated for another 2 weeks. At the end of the 1 month period of measurements for both groups of drivers, the Wait-list drivers will then receive a HEPA air purifier, so that they may also potentially benefit from the intervention being tested in this study, but no further measurements will be taken. |
