Integrating Methadone Services Into Primary Care in Ukraine: Two-Year Outcomes From a Randomized Trial
Opioid use disorder (OUD) drives high morbidity and mortality, but access to opioid agonist therapy (OAT) is limited in low- and middle-income countries. Integrating OAT into primary care may expand access and improve comorbidity management, although provider discomfort remains a barrier. To compare health care use among persons with OUD receiving methadone in specialty clinics versus primary care centers in Ukraine (January 2018 to December 2023). Two-group randomized controlled trial with 2:1 allocation to intervention and control. (ClinicalTrials.gov: NCT04927091). Thirteen cities in Ukraine: Cherkasy, Dnipro, Kramatorsk, Kropyvnytskyi, Kryvyi Rih, Kyiv, Lviv, Mariupol, Mykolaiv, Odesa, Rivne, Sloviansk, and Zhytomyr. A total of 1459 adults with OUD (950 intervention, 509 control) initiating or receiving methadone. Methadone delivered in primary care aided with telementoring, an Extension for Community Healthcare Outcomes-like model that is adapted to the Ukraine context, versus standard specialty clinic care. Primary outcome: difference in composite quality health indicator (QHI) scores between groups at 24 months, representing access to 17 guideline-concordant services (9 primary care and 8 specialty care) received, assessed through surveys and ranging from 0 to 100. Secondary outcomes: domain-specific QHI scores and methadone treatment indicators. Participants in primary care settings achieved higher composite QHI scores than those in specialty clinics, with a mean difference of 9.1 percentage points (95% CI, 6.9 to 11.2 percentage points) at 24 months. Results were similar for primary care QHI (12.3 percentage points [CI, 9.0 to 15.6 percentage points]) and specialty care QHI (5.2 percentage points [CI, 0.2 to 10.3 percentage points]). Methadone retention among new patients at 24 months was 67.2% in primary care versus 64.7% in specialty clinics. Quality health indicators reflect health care use rather than health outcomes. Quality health indicators were equally weighted despite differing clinical significance. Integrating methadone treatment into primary care settings improves adherence to guideline-concordant health care without compromising methadone retention and treatment quality.

Clinical characteristics associated with problematic pornography use among individuals seeking treatment for opioid use disorder
Background and Aims: Many jurisdictions are experiencing opioid epidemics. Opioid use disorder (OUD) often co-occurs with other psychiatric disorders including behavioral addictions like gambling disorder. However, little is known regarding the frequency and correlates of problematic pornography use (PPU) among people seeking treatment for OUD. Here we aimed to investigate PPU and its correlates in people seeking OUD treatment.Method: From October 2018 to March 2020, 1,272 individuals seeking OUD treatment were screened for PPU by completing the Brief Pornography Screen (BPS), a 5-item instrument validated for assessing PPU. Self-reported data were used.Results: Among the sample there were 707 (60%) males and 565 (40%) females. The mean age of participants was 37.9 ± 10.5 years (range 18–73), there were 707 (60%) males and 565 (40%) females, 9.9% (n = 126) exhibited low positive BPS scores (1 ≤ score < 4), and 4.5% of the sample (n = 57) screened positive for PPU (BPS score ≥4). Individuals screening positive for PPU versus negative were mostly male (77%), scored higher on measures of impulsivity in the domains of positive urgency, negative urgency, and sensation-seeking and demonstrated more psychopathology on measures of substance use, psychotic symptoms, emotional lability, depression/functioning and self-harm.Discussion and Conclusion: A minority of individuals seeking treatment for OUD screened positive for PPU. Among individuals with OUD, those screening positive (versus negative) for PPU were more impulsive and experienced more psychiatric symptoms, suggesting the need for additional investigation and screening for and addressing PPU in people with OUD.

Trajectory and progress of opioid agonist therapy programs in the Kyrgyz Republic
The incidence and mortality of human immunodeficiency viruses (HIVs) are rising in Eastern Europe and Central Asia (EECA), particularly among people who inject drugs. Opioid agonist therapies (OATs), such as methadone or buprenorphine, are the most effective treatments for opioid use disorder and serve as a key HIV-prevention strategy in EECA. OAT uptake across the region, however, has been limited. The Kyrgyz Republic was the first Central Asian country to initiate OAT and remains a pioneer in the region. To understand the progression of OAT scale-up, all legislations related to drug policies or methadone in the Kyrgyz Republic were analyzed from the country’s founding to March 2023 and compared with policies in neighboring countries, particularly Kazakhstan and Tajikistan. Concurrently, local news coverage and policy reports were also assessed. OAT has been available in the Kyrgyz Republic since 2001, initially as a pilot project funded by international donors, and then with gradually increasing state support. Since its inception, the methadone program has evolved and influenced neighboring countries in Central Asia, despite numerous political challenges. The Kyrgyz Republic has expanded access to methadone, revised clinical protocols, and increased the number of distribution sites in communities and the carceral system to ensure broader access, aiming for program sustainability. While methadone policies and implementation in the Kyrgyz Republic have advanced earlier and more expansively than in neighboring countries, some challenges persist. Based on the findings, the suggestions provided may support the sustainable scale-up of methadone programs, enabling continued growth and improvement.

Stalled Scale-Up of Opioid Agonist Therapies for HIV Prevention in Kazakhstan: History, Policy, and Recommendations for Change
HIV incidence and mortality are increasing in Eastern Europe and Central Asia and are concentrated in people who inject drugs. Maintenance with opioid agonist therapies (OAT) like methadone or buprenorphine is the best treatment for opioid use disorder and a key HIV-prevention strategy in the region. In Kazakhstan, the scale-up of methadone has been minimal since methadone’s introduction in 2008 and has been supported through international charitable organizations. As the Republic of Kazakhstan is designated to assume financial and administrative oversight of OAT, legislative gains can ensure treatment continuity and scale-up. Here, we review legislative barriers to OAT scale-up in Kazakhstan using an implementation science lens. We review legislative, political, and cultural barriers that undermine the efficient distribution and allocation of medications and impose burdensome clinical and administrative demands on patients and clinicians. Legislative reform is required to support further OAT expansion. We therefore provide policy recommendations to overcome these barriers to increase access to this life-saving, life-prolonging, evidence-based medical treatment. Minimally, these include increased numbers of clinical sites and patients at these sites; re-engineering OAT delivery across the country and directly to patients; introducing newer formulations of OAT; and creating an open bidding process to procure treatment medications.

The development and initial validation of the Russian version of the BASIS-24
Background: Efficient and linguistically appropriate instruments are needed to assess response to addiction treatment, including severity of addiction/mental health status. This is critical for Russian-speaking persons in Eastern Europe and Central Asia (EECA) where Medications for Opioid Use Disorder (MOUD) remain underscaled to address expanding and intertwined opioid, HIV, HCV and tuberculosis epidemics. We developed and conducted a pilot validation of a Russian version of the 24-item Behavior and Symptom Identification Scale (BASIS-24), an addiction/mental health severity instrument with six subscales, previously validated in English. Methods: Using the Mapi approach, we reviewed, translated, and back-translated the content to Russian, pilot-tested the Russian-version (BASIS-24-R) among new MOUD patients in Ukraine (N = 283). For a subset of patients (n = 44), test-rest was performed 48 h after admission to reassess reliability of BASIS-24-R. Exploratory principal component analysis (PCA) assessed underlying structure of BASIS-24-R. Results: Cronbach alpha coefficients for overall BASIS-24-R and 5 subscales exceeded 0.65; coefficient for Relationship subscale was 0.42. The Pearson correlation coefficients for overall score and all subscales on the BASIS-24-R exceeded 0.8. Each item loaded onto factors that corresponded with English BASIS-24 subscales ≥ 0.4 in PCA. Conclusion: Initial version of BASIS-24-R appears statistically valid in Russian. Use of the BASIS-24-R has potential to guide MOUD treatment delivery in the EECA region and help to align addiction treatment with HIV prevention goals in a region where HIV is concentrated in people who inject opioids and where healthcare professionals have not traditionally perceived MOUD as effective treatment, particularly for those with mental health co-morbidities.
