Costs of syringe vending machines in Tbilisi, Georgia.

BACKGROUND: Syringe vending machines (SVM) can improve access to sterile injecting equipment, but they have not been widely implemented or evaluated. We evaluate the cost of SVM installed between July 2019-December 2020 in Tbilisi, Georgia. METHODS: The SVM were stocked with several kit types, including injecting equipment for opioid or stimulant users, naloxone, male and female condoms, and pregnancy tests. We gathered financial data from the project to estimate fixed (staff time, start-up costs, equipment, running costs, and consumables) and variable (harm reduction kits) costs. We calculated the full cost of the SVM intervention, cost per user, cost per additional syringe accessed by SVM users, and cost per kit distributed (2020 Euros). RESULTS: SVM access cards were issued to 1132 users, and 29,238 kits were distributed through SVM, total cost €204,358. Staff costs were 51% of total, consumable costs 28%, equipment 10%, and start up, recurrent costs, and overheads 5% or less each. Opioid and stimulant kits were most accessed (35% and 32% of total). Cost per user was €66/year, and cost per transaction €7, of which €5 fixed costs and €2 variable. If monthly transactions increased from the average of 1622/month to highest monthly usage (4714), fixed costs per transaction would decrease to < €1. It cost €0.55 per additional syringe accessed/user/month. CONCLUSIONS: This study provides evidence for governments about the cost of SVM, a novel harm reduction intervention. This is particularly relevant where Global Fund is withdrawing and harm reduction services need to be incorporated into national budgets.

Implementation and evaluation of a syringe vending machine trial in Tbilisi, Georgia.

BACKGROUND: Syringe vending machines (SVM) have proven to be an effective vehicle for providing an uninterrupted supply of sterile equipment to PWID, but they have not been implemented or disseminated broadly. The aim of this study was to implement and evaluate outcomes of introducing SVM in Tbilisi, Georgia. METHODS: We installed SVM at five HIV prevention sites in 10 locations in Tbilisi, Georgia and studied implementation over 20 months. We used the RE-AIM framework to assess outcomes across four RE-AIM domains: reach, effectiveness at providing syringe access, adoption and implementation. RESULTS: Reach. SVM reached 8% of the target population. Effectiveness at Providing Syringe Access. SVM dispensed 14% of all syringes distributed by HIV prevention services. Using SVM was associated with PWID receiving more sterile syringes from HIV prevention outlets. Adoption. All HIV prevention sites (N=5) invited to implement SVM agreed to participate. Sixty one percent of PWID who received SVM access cards used SVM at least once. Women and young PWID were more likely to use SVM compared to other PWID. IMPLEMENTATION: At some sites adherence of the outreach staff to the operational protocol was suboptimal. CONCLUSIONS: SVM are an acceptable, feasible and effective intervention for improving access to sterile injection equipment for PWID. Future research will need to elaborate approaches to build the sense of ownership and improve motivation of the field staff to engage with the new intervention, and to examine strategies for attracting groups of PWID who are not in contact with prevention and treatment services.

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

OBJECTIVE: Syringe vending machines (SVMs) are intended to supplement the standard syringe exchange programs to access hard-to-reach groups and to cover unserved geographical areas. This report describes how we adapted SVMs to deliver interventions and collect research data as part of a study of smart SVMs (SSVMs) in Tbilisi, Georgia. METHOD: To create SSVMs, we upgraded commercial vending machines and developed a computer program to track and record interactions and to display messages related to study procedures. Preferred locations for SSVMs, product specifications, and the mode of operation were determined through formative input from people who inject drugs (PWID). SSVMs were installed near pharmacies and serve both the general population and PWID. The "hidden" interactive menu for the PWID prevention kits was displayed on the screen only when a special plastic card was used. The plastic cards were distributed to the clients of fixed syringe exchange programs and to their peers who were not in contact with harm-reduction services. RESULTS: Ten SSVMs were operational in Tbilisi as of March 2021, with more than 800 PWID using them on a regular basis. More than half of sterile equipment kits were distributed during weekends and night hours. CONCLUSIONS: Our innovative SSVM integrates features for intervention delivery and research data collection. It can be used for testing a variety of interventions beyond syringes (e.g., distribution of HIV/hepatitis C virus self-tests) and provides opportunities for serving various at-risk groups that might not otherwise access these products and services (e.g., men who have sex with men, commercial sex workers).

Perceived acceptability of and willingness to use syringe vending machines: results of a cross-sectional survey of out-of-service people who inject drugs in Tbilisi, Georgia.

BACKGROUND: The growing HIV epidemic in Eastern Europe and Central Asia has been driven by high rates of injection drug use. The Republic of Georgia has among the highest injection drug use rates globally, with a prevalence of 2.24%. The reach of evidence-based HIV prevention interventions like needle and syringe programs (NSP) among people who inject drugs (PWID) has remained below rates that could significantly impact the epidemic. Syringe vending machines (SVM) are an effective and cost-effective supplement to standard NSP; if acceptable to PWID, SVM could reach hard-to-reach PWID and cover geographic areas where fixed or mobile NSPs do not operate. The aim of this study was to assess the perceived acceptability of SVM among out-of-service (harm reduction or substance use treatment) PWID in Tbilisi, Georgia. METHODOLOGY: Participants were recruited using respondent-driven sampling (RDS) to participate in cross-sectional, face-to-face interviews. We conducted individual interviews using a structured questionnaire that covered participants' socio-demographics, drug use practices, and perceived acceptability of SVM. Uni-variate analyses were employed for data analysis. RESULTS: The final sample (n = 149) was almost exclusively male with a mean age of 42.2 years and mean years of injection drug use of 14.4 years. Heroin, buprenorphine, and stimulants were the main drugs injected. Eighty-five percent of the sample had never received any harm reduction services, and 30% had never been tested for HIV. Fifteen percent of the sample reported sharing injection equipment with others during last month. All but one participant agreed that PWID would benefit from SVM and 145 (97%) said they would personally use SVM. Ninety percent of those sampled stated that they would use HIV self-tests if available from vending machines. The most highly endorsed features of SVM were provision of free injection equipment, no need to deal with pharmacies, uninterrupted 24/7 access, and availability of HIV self-testing kits. DISCUSSION: Perceived acceptability of syringe vending machines was extremely high among PWID not currently receiving any harm reduction or treatment services, with strong support indicated for uninterrupted free access to sterile injection equipment, privacy, and anonymity. Introducing SVM in Georgia holds the potential to deliver significant public health benefits by attracting hard-to-reach PWID, reducing unsafe injection behavior, and contributing to HIV testing uptake and linkage to care.

Republic of Georgia estimates for prevalence of drug use: Randomized response techniques suggest under-estimation.

BACKGROUND: Validity of responses in surveys is an important research concern, especially in emerging market economies where surveys in the general population are a novelty, and the level of social control is traditionally higher. The Randomized Response Technique (RRT) can be used as a check on response validity when the study aim is to estimate population prevalence of drug experiences and other socially sensitive and/or illegal behaviors. AIM: To apply RRT and to study potential under-reporting of drug use in a nation-scale, population-based general population survey of alcohol and other drug use. METHODS: For this first-ever household survey on addictive substances for the Country of Georgia, we used the multi-stage probability sampling of 18-to-64-year-old household residents of 111 urban and 49 rural areas. During the interviewer-administered assessments, RRT involved pairing of sensitive and non-sensitive questions about drug experiences. RESULTS: Based upon the standard household self-report survey estimate, an estimated 17.3% [95% confidence interval, CI: 15.5%, 19.1%] of Georgian household residents have tried cannabis. The corresponding RRT estimate was 29.9% [95% CI: 24.9%, 34.9%]. The RRT estimates for other drugs such as heroin also were larger than the standard self-report estimates. DISCUSSION AND CONCLUSIONS: We remain unsure about what is the "true" value for prevalence of using illegal psychotropic drugs in the Republic of Georgia study population. Our RRT results suggest that standard non-RRT approaches might produce 'under-estimates' or at best, highly conservative, lower-end estimates.

Policing, massive street drug testing and poly-substance use chaos in Georgia - a policy case study.

BACKGROUND: Since early 2000, intensive policing, wide scale street drug testing, and actions aimed at limiting the availability of specific drugs have been implemented in Georgia. Supporters of this approach argue that fear of drug testing and resulting punishment compels drug users to stop using and prevents youth from initiating drug use. It has been also stated that reduction in the availability of specific drugs should be seen as an indication of the overall success of counter-drug efforts. The aim of the current review is to describe the drug-related law enforcement response in Georgia and its impact on illicit drug consumption and drug-related harm. METHOD: We reviewed relevant literature that included peer-reviewed scientific articles, stand-alone research reports, annual drug situation reports, technical reports and program data. This was also supplemented by the review of relevant legislation and judicial practices for the twelve year period between 2002 and 2014. RESULTS: Every episode of reduced availability of any "traditional" injection drug was followed by the discovery/introduction of a new injection preparation. The pattern of drug consumption was normally driven by users' attempts to substitute their drug of choice through mixing together available alternative substances. Chaotic poly-substance use and extensive utilization of home-made injection drugs, prepared from toxic precursors, became common. Massive random street drug testing had little or no effect on the prevalence of problem drug use. CONCLUSIONS: Intensive harassment of drug users and exclusive focus on reducing the availability of specific drugs did not result in reduction of the prevalence of injecting drug use. Repressive response of Georgian anti-drug authorities relied heavily on consumer sanctions, which led to shifts in drug users' behavior. In most cases, these shifts were associated with the introduction and use of new toxic preparations and subsequent harm to the physical and mental health of drug consumers.
