Aim. Needle and syringe programs (NSP) are evidence-based intervention to prevent HIV infection among people who inject drugs (PWID). Syringe Vending Machines (SVM) intend to supplement the standard NSP to reach hard to reach groups and to cover unserved geographical areas. The aim of the ongoing parent implementation trial is to evaluate the implementation process (and effectiveness) of SVM in Tbilisi, Republic of Georgia.
Description. We upgraded commercial vending machines to serve both product distribution and research data collection purposes. The hardware upgrade included a Raspberry Pi, an LCD touchscreen, an internet modem, and an RFID card reader. We developed a computer program to track and record every interaction and to display appropriate messages related to study procedures. Machines are monitored and administered remotely. Preferred locations for SVMs, PWID product specifications, and the mode of operation were all determined at the formative stage. SVMs are installed near pharmacies and serve both the general population and the PWID. Upper 2 shelves are stocked with general health products for purchase. Lower 3 shelves are covered by the HCV/HIV prevention poster so the products behind them can’t be seen from outside. The “hidden” interactive menu for the PWID prevention kits is displayed on the screen only when a special plastic card is used. The plastic cards are distributed to the clients of fixed NSPs and to their peers who are not in contact with harm reduction services. The SVM also provides a brief on-screen survey for beneficiaries. More detailed data (socio-demographics, drug use, risk behavior, feedback on SVMs) is collected via an online survey.
Conclusion. Six SVMs are operational in Tbilisi as of December 2019 and preliminary data suggests they are serving their purpose well. Our innovative solution integrates features for intervention delivery and research data collection. It can provide infrastructure for testing new research ideas and interventions (e.g. distribution HIV/HCV self-tests).
