Smart Syringe Vending Machines: Research Capabilities and Implications for Research Data Collection

Area of Science:

• Public Health
• Health Informatics
• Harm Reduction

Background:

• Syringe vending machines (SVMs) aim to improve access to sterile syringes for people who inject drugs (PWID) in underserved areas.
• Standard syringe exchange programs (SEPs) face challenges in reaching all at-risk populations and geographical locations.

Purpose of the Study:

• To adapt and evaluate smart syringe vending machines (SSVMs) for delivering health interventions and collecting research data in Tbilisi, Georgia.
• To assess the feasibility of using SSVMs to supplement existing harm reduction services and reach populations not currently engaged with SEPs.

Main Methods:

• Commercial vending machines were upgraded with a computer program for tracking interactions and displaying messages.
• Formative input from PWID guided the selection of SSVM locations, product offerings, and operational modes.
• A "hidden" interactive menu for prevention kits was accessed via a special plastic card distributed through SEPs and peer networks.

Main Results:

• Ten SSVMs were operational, serving over 800 PWID regularly by March 2021.
• A significant proportion of sterile equipment kits were dispensed during non-traditional hours (weekends and nights).

Conclusions:

• The developed SSVM successfully integrates intervention delivery and research data collection capabilities.
• SSVMs offer a scalable platform for distributing a wider range of health products (e.g., self-tests) and reaching diverse at-risk groups.
• This technology enhances the reach of harm reduction services to populations that may face barriers accessing traditional programs.
