Clinical Trial Summary

This study will validate a wrist-worn alcohol monitor (BACtrack Skyn) in both laboratory and real-life settings.

Description:

The overarching goal of this research program is to improve alcohol intervention and eventually related clinical outcomes (e.g., liver function) among HIV+ drinkers through biosensor-assisted intervention. Research shows HIV infection can influence alcohol metabolism (i.e., higher blood alcohol levels), so it's necessary to validate the new alcohol biosensor in HIV+ drinkers rather than in general population. The primary goal of this project, as a step toward the development and evaluation of a biosensor-assisted alcohol intervention, is to validate the newly available wrist worn transdermal alcohol biosensor (BACtrack Skyn). The two specific aims are: (1) To assess validity and reliability of the Skyn biosensor using fixed-dose lab administration of alcohol through comparison with laboratory grade breathalyzer, and (2) To validate Skyn biosensor in daily life using a 2-week ecological momentary assessment (EMA) to compare self-reported drinking and the Skyn derived transdermal alcohol concentration (TAC) readings.

Eligibility

Inclusion Criteria:

• HIV+ consumers of alcohol; self-reported = 5 days with at least 1 alcoholic drink, and =1days with at least 3 drinks

• HIV- consumers of alcohol; self-reported = 5 days with at least 1 alcoholic drink, and =1days with at least 3 drinks

• HIV Infections
• Human Immunodeficiency Virus (HIV)

Intervention

Device:
• Skyn Monitor Lab Session 1
Participants will be instructed to wear the Skyn wrist-worn alcohol monitor and drink 3 beers over the course of an hour and a half. BrAC will be measured every 15 minutes throughout the session.
• Skyn Monitor Field Test with EMA App
After Skyn Monitor Lab Session 1, participants will be instructed to wear Skyn monitor for the rest of the day and the following two weeks. Participants will also enter information on each drinking session during the two week time using a mobile-based ecological momentary assessment (EMA) to collect real-time data in daily life.
• Skyn Monitor Lab Session 2
Participants will be instructed to wear the Skyn wrist-worn alcohol monitor and drink 3 beers over the course of an hour and a half. BrAC will be measured every 15 minutes throughout the session. Participant will also complete device acceptability and usability survey.
