Clinical Trial Summary

The goal of this study is to conduct a laboratory-based pilot randomized control trial of smartphone-enabled breath alcohol monitoring on perceived fitness to drive a vehicle among intoxicated adults. We will enroll up to 30 adults aged > 21-44 who are frequent drinkers without dependence who drive more than four times per week to complete a standardized alcohol drinking protocol in a monitored setting collecting breathalyzer measurements. The protocol involves consuming three weight-based doses of alcohol with a target BAC of 0.10 and completing breathalyzer measurements every 20 minutes until a BAC of 0.03 is reached. The control group will complete a visual analog scale on their perceived fitness to drive and be blinded to their breath alcohol readings with the BACtrack Mobile Pro breathalyzer device, while the intervention group would do the same, but be shown their breath alcohol readings on the paired BACtrack smartphone application. Our previous research has validated the accuracy of the BACtrack Mobile Pro device to measure BAC within +/- 0.001 of police-grade breathalyzer and estimate BAC within +/- 0.01 of a blood test.
