Decolonizing addiction treatment in Eastern Europe and Central Asia: Confronting Russian narcology and Western retreat
Eastern Europe and Central Asia (EECA) face a dual crisis in addiction treatment. On one side, Russian imperial legacies persist through punitive "narcology," now weaponized amid ongoing aggression. On the other, Western retrenchment, marked by abrupt aid suspensions and dwindling harm-reduction budgets, has weakened the evidence-based counterweight that once challenged authoritarian approaches. The result is a convergence of punitive logics that…
Decrease in provider stigma is associated with improved quality health indicators among individuals receiving methadone in primary care centers in Ukraine
A pilot implementation study to scale-up methadone in incarcerated persons with opioid use disorder and retain them on treatment after release in Moldova
The SBIRT strategy significantly improved participant attitudes, but treatment initiation mostly occurred after completing both sessions, including soon after release, but remained low overall. Work within the Moldovan prison subculture to dispel negative myths and misinformation is needed to further scale-up OAT in Moldova
Addiction Treatment as Prison Governance: A Critical Discourse Analysis of Methadone Delivery in Kyrgyz Prisons
Methadone treatment is prescribed by evidence-based medicine as the most effective tool for the treatment of opioid addiction. Its implementation into high-need prison settings worldwide has been met with challenges, particularly in Eastern Europe and Central Asia where the opioid epidemic continues to expand. To address these impasses to intervention translation, we turn to post-structural approaches to policy analysis. These approaches open spa…
Divergent estimates of HIV incidence among people who inject drugs in Ukraine
Perceptions of Health-Related Community Reentry Challenges among Incarcerated Drug Users in Azerbaijan, Kyrgyzstan, and Ukraine
Retention in medication-assisted treatment programs in Ukraine—Identifying factors contributing to a continuing HIV epidemic
Willingness to pay for opioid agonist treatment among opioid dependent people who inject drugs in Ukraine
Using nominal group technique among clinical providers to identify barriers and prioritize solutions to scaling up opioid agonist therapies in Ukraine
Why People Who Inject Drugs Voluntarily Transition Off Methadone in Ukraine
Methadone maintenance therapy (MMT) treats opioid use disorder among people who inject drugs (PWID). To understand why PWID may voluntarily discontinue MMT, we analyzed data from 25 focus groups conducted in five Ukrainian cities from February to April 2013 with 199 participants who were currently, previously, or never on MMT. Using constant comparison method, we uncovered three themes explaining why PWID transition off MMT: (a) purposeful resist…
Attitudes Toward Addiction, Methadone Treatment, and Recovery Among HIV-Infected Ukrainian Prisoners Who Inject Drugs: Incarceration Effects and Exploration of Mediators
Intersecting epidemics of HIV, HCV, and syphilis among soon-to-be released prisoners in Kyrgyzstan: Implications for prevention and treatment
Accessing methadone within Moldovan prisons: Prejudice and myths amplified by peers
BACKGROUND: The volatile HIV epidemic in Moldova, driven primarily by people who inject drugs (PWIDs), is concentrated in prisons. Although internationally recommended opioid agonist therapy (OAT) is available in Moldovan prisons, coverage remains inadequate and expansion efforts have failed to meet national and international goals. METHODS: To better understand why eligible prisoners are reluctant to initiate OAT, we surveyed recently released p…

Individual and Network Interventions With Injection Drug Users in 5 Ukraine Cities
Objectives. We evaluated the effects of an individual intervention versus a network intervention on HIV-related injection and sexual risk behaviors among street-recruited opiate injection drug users in 5 Ukraine cities. Methods. Between 2004 and 2006, 722 opiate injection drug users were recruited to participate in interventions that were either individually based or based on a social network model in which peer educators intervened with their ne…
“We fear the police, and the police fear us”: Structural and individual barriers and facilitators to HIV medication adherence among injection drug users in Kiev, Ukraine
Ukraine has one of the most severe HIV/AIDS epidemics in Europe, with an estimated 1.63% of the population living with HIV/AIDS in 2007. Injection drug use (IDU) remains the predominant mode of transmission in Kiev - the capital and largest city. Prior reports suggest that the HIV infection rate among IDUs in Kiev reaches 33%, and many have poor and inequitable access to highly active antiretroviral therapy (HAART). Among those with access to HAA…
