About

Central Asia (CA) represents the most rapidly growing HIV epidemic region worldwide, concentrated in people who inject drugs (PWID) and their sexual partners, and scaling up opioid agonist therapies (OAT) in this region is the most cost-effective strategy to prevent new HIV infections, and more effective when combined with antiretroviral therapy (ART). The investigators propose to use the Network for the Improvement of Addiction Treatment (NIATx) implementation strategy to scale-up OAT in three diverse Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan) and guided by the Exploration-Planning-Implementation-Sustainment (EPIS) framework. Understanding the trajectories of implementation and scale-up in this context may emerge through creating communities of practice, especially when cohesion and competence evolves, and may guide other healthcare delivery challenges in the region (e.g., HIV, TB); as well as build important regional expertise and understanding implementation trajectories should help support OAT program sustainability.

Full description

Central Asia (CA) represents the most rapidly growing HIV epidemic region worldwide, concentrated in people who inject drugs (PWID) and their sexual partners. Scaling up opioid agonist therapies (OAT) in CA is the most cost-effective strategy to prevent new HIV infections, and more effective when combined with antiretroviral therapy (ART). OAT, when adequately scaled, controls HIV epidemics through both primary and secondary prevention (increased engagement along the entire HIV treatment cascade). CA countries have especially low OAT (and ART) coverage and are uniquely impacted by their proximity to opioid trade routes, a myriad of patient, provider, healthcare and policy barriers and suboptimal implementation. CA countries share a similar Semashko healthcare system, but differ by political, cultural and economic trajectories since independence from the Soviet Union. Such healthcare systems are especially challenging for implementation of evidence-based practices (EBPs). Moreover, the HIV treatment cascade differs in Kazakhstan (KZ), Kyrgyzstan (KY) and Tajikistan (TJ) with low levels of HIV testing (71%, 61% and 48%), being on ART (~30%) and viral suppression (20%, 18%, 22%), respectively. OAT coverage is similarly low (0.2%, 4.6% and 2.8%) for the 120,500, 25,000 and 22,500 PWID, respectively. The investigators propose to use the Network for the Improvement of Addiction Treatment (NIATx) implementation strategy to scale-up OAT in three diverse CA countries guided by the Exploration-Planning-Implementation-Sustainment (EPIS) framework.

Using the investigators experiences with NIATx to scale-up OAT in Ukraine, the EPIS framework will be used where the investigators will first assess the barriers and facilitators to OAT scale-up, including inner and outer context and bridging factors associated with OAT innovations as part of exploration/preparation. Despite its unequivocal efficacy, it was perceived as negative by both patients and providers in Ukraine. Myths surrounding OAT combined with structural factors within clinics accounted for 82% of the barriers. The investigators then implemented NIATx by training in-country coaches and used a menu of tools and quality improvement techniques to scale-up OAT to increase OAT entry and retention. EPIS relies on dynamic use of implementation to adapt to the context. Collaborative learning is key feature of NIATx that involves a transformation to adoption and scale-up of EBPs. OAT implementation, however, requires adaptation of implementation strategies to local contextual factors, including available resources, expertise, and cultural norms, which must be accomplished for successful implementation. Such adaptation, however, must be understood to promote sustainability and to install promising practices that are unique to the context. Health delivery in CA is based on vestiges of Soviet-era Semashko health systems which are siloed, rigidly vertical and do not promote teamwork. Observations from Ukraine suggest that group cohesion may emerge through collaborative learning, but it is not linear and outcomes among group members differ. Understanding the trajectories of implementation, a core feature of EPIS, may in this context emerge through creating communities of practice, especially when cohesion evolves, and may guide other healthcare delivery challenges in the region (e.g., HIV, TB). Using NIATx to build important regional expertise and understanding implementation trajectories should help support OAT program sustainability. The specific aims are:

1. To create a socio-ecological framework for OAT delivery by conducting formative research to assess client-level, program-level and structural facilitators and barriers to entry into and retention in OAT in each country in order to create improved, sustainable models of OAT delivery that are contextually relevant, including integration of OAT into primary and HIV clinical care settings.
2. To scale-up OAT in 3 diverse Central Asian countries by training and coaching national experts in Kazakhstan (KZ), Kyrgyzstan (KG) and Tajikistan (TJ) on the use of NIATx.
3. To use latent class growth analyses to identify implementation trajectories of OAT, scale-up using NIATx in the Eastern Europe and Central Asia (EECA) context and explore which organizational, professional and group dynamic characteristics are associated with these trajectories and related to individual level outcomes (i.e., OAT scale-up).

As part of the implementation and sustainability plan, and consistent with NIATx, the investigators will convene stakeholder meetings to bridge inner (National and Oblast Chief Narcologists) and outer (e.g. Non-Governmental Organization (NGOs), Ministry of Health, external funders and experts) factors to guide initial implementation, review findings from the investigators studies and use information to inform policies for expanding OAT in each CA country. These meeting will inform implementation and guide structural policy changes to promote sustainability. Significance is high given CA having the most rapidly evolving HIV epidemic worldwide, concentrated in PWID and their sexual partners and where current implementation efforts have failed. Innovation is high by using NIATx and its extensive toolkit to facilitate OAT scale-up alongside an in-depth assessment of key NIATx elements that contribute to success in this context. Success is likely to be high given the experience of the US and Central Asian teams, their previous collaborative research and a common goal to control HIV in the region. Public health benefit is likely to be high given the need to simultaneously address both treatment and prevention of HIV and opioid use disorder (OUD).
