Assessment of methadone clinic staff attitudes toward hepatitis C evaluation and treatment

Engaging people who use drugs in clinical research: integrating facilitated telemedicine for HCV into substance use treatment

BACKGROUND

People who use drugs (PWUD) have difficulty participating in clinical research. We evaluated approaches to engage PWUD in clinical research, using facilitated telemedicine for hepatitis C virus (HCV) care as an example.

METHODS

We analyzed stakeholder interview transcripts and study-related data (i.e., progress reports, meeting minutes) from interrelated studies to understand engagement experiences at the patient, site, and organizational levels. Stakeholders include patient-participants, opioid treatment program (OTP) staff and administrators, and research team members involved in HCV management through facilitated telemedicine integrated into OTPs.

RESULTS

Three themes emerged. Initially, the research team sought understanding of the unique culture and community of each OTP (Theme 1). The team built trusting relationships through education, communication, and feedback (Theme 2). Finally, the research team enhanced collaborative care and incorporated the patients' voice to improve health outcomes (Theme 3). Patient-participants and OTP staff endorsed the integrated HCV care approach. Engagement practices are summarized as the CREATE framework (C = culture, R = respect, E = educate, A = advantage, T = trust, E = endorse).

CONCLUSIONS

PWUD engagement in clinical research is maximized by building trusting relationships with open communication channels. Understanding the community, demonstrating respect, and augmenting knowledge are foundational for engaging PWUD in clinical research. These practices are transferable to engagement of PWUD in clinical research broadly.

Multi-level implementation factors that influence scale-up of methadone maintenance treatment in Moldovan prisons: A qualitative study

INTRODUCTION

People who inject drugs (PWID) are overrepresented in prison populations, especially in the Eastern European and Central Asian region (EECA), where HIV incidence and mortality continue to rise. Modeling data suggest that methadone maintenance treatment (MMT) scale-up in prison with continuation after release could substantially reduce new HIV infections. Moldova, one of four countries in the EECA to have introduced MMT in prisons, has faced challenges with its scale-up.

METHOD

To improve implementation of MMT in Moldovan prisoners, we analyzed the qualitative interviews of 44 recently released Moldovan prisoners with opioid use disorder who either accepted or rejected MMT while incarcerated; these 44 were among a subset of 56 participants in a quantitative survey who had complete interview data. After translating and back-translating interviews, we used content analysis to identify key barriers and facilitators to MMT uptake.

RESULTS

Our qualitative analyses revealed that positive attitudes toward methadone facilitated treatment uptake, yet the study identified three thematic barriers as to why PWID do not accept MMT while in prison, including: 1) negative personal attitudes toward MMT; 2) stigmatization of MMT by informal hierarchies within prison; and 3) distrust of the formal prison hierarchy (i.e., administration), which provides MMT.

CONCLUSION

Overall, the social forces of the two prisoner hierarchies and distrust between them appeared to outweigh the perceived benefits of MMT and impacted MMT uptake. Here we provide strategies to promote MMT more effectively in prison settings.

CDC Recommendations for Hepatitis C Screening Among Adults - United States, 2020

Hepatitis C virus (HCV) infection is a major source of morbidity and mortality in the United States. HCV is transmitted primarily through parenteral exposures to infectious blood or body fluids that contain blood, most commonly through injection drug use. No vaccine against hepatitis C exists and no effective pre- or postexposure prophylaxis is available. More than half of persons who become infected with HCV will develop chronic infection. Direct-acting antiviral treatment can result in a virologic cure in most persons with 8-12 weeks of all-oral medication regimens. This report augments (i.e., updates and summarizes) previously published recommendations from CDC regarding testing for HCV infection in the United States (Smith BD, Morgan RL, Beckett GA, et al. Recommendations for the identification of chronic hepatitis C virus infection among persons born during 1945-1965. MMWR Recomm Rec 2012;61[No. RR-4]). CDC is augmenting previous guidance with two new recommendations: 1) hepatitis C screening at least once in a lifetime for all adults aged ≥18 years, except in settings where the prevalence of HCV infection is <0.1% and 2) hepatitis C screening for all pregnant women during each pregnancy, except in settings where the prevalence of HCV infection is <0.1%. The recommendation for HCV testing that remains unchanged is regardless of age or setting prevalence, all persons with risk factors should be tested for hepatitis C, with periodic testing while risk factors persist. Any person who requests hepatitis C testing should receive it, regardless of disclosure of risk, because many persons might be reluctant to disclose stigmatizing risks.

Liver Disease and Fibrosis Assessment in Substance Use-Related Disorders

Substance users have the highest prevalence of hepatitis C virus (HCV) infection but have rarely been treated, largely because of their mistrust of the health care system, misconceptions about the consequences of the infection, and concerns regarding interferon-related side effects. With the development of highly efficacious, interferon-free therapeutic regimens without significant side effects, the concept of colocating HCV and substance use treatment would appear to be highly feasible. This process has been further facilitated by widespread clinical adaptation of noninvasive assays for fibrosis assessment, which could be performed routinely in substance use treatment facilities. The most commonly used noninvasive fibrosis assessment methods are serum marker indexes and transient elastography, both of which are very accurate in detecting cirrhosis or the absence of fibrosis, but much less successful in identifying intermediate fibrosis stages. The effect of drugs of abuse on the liver is not completely understood or sufficiently studied. There are no indications that heroin and cocaine affect fibrosis progression, but some recreational drugs (eg, alcohol and cannabis) can induce hepatic injury. In addition, knowledge gaps exist on the effect of impaired liver function on metabolism or transport of agents used to treat substance disorders as well as their interactions with HCV antivirals.

Treatment of Chronic Hepatitis C in Patients Receiving Opioid Agonist Therapy: A Review of Best Practice

Injection drug use is the most common transmission route for hepatitis C. High rates of infection are observed among individuals on opioid agonist therapy. Although people who inject drugs carry the highest burden, few have initiated treatment. We present a comprehensive review of the evidence on the efficacy of HCV medications, drug-drug interactions, and barriers to and models of care. Studies have demonstrated comparable efficacy for individuals who are on opioid agonist therapy compared with those who are not. We propose that a strategy of treatment and cure-as-prevention is imperative in this population to curb the hepatitis C epidemic.

The Future of Opioid Agonist Therapies in Ukraine: A Qualitative Assessment of Multilevel Barriers and Ways Forward to Promote Retention in Treatment

Opioid agonist therapies (OAT) to treat opioid addiction in people who inject drugs (PWID) began in Ukraine in 2004. Scale-up of OAT, however, has been hampered by both low enrollment and high attrition. To better understand the factors influencing OAT retention among PWID in Ukraine, qualitative data from 199 PWIDs were collected during 25 focus groups conducted in five Ukrainian cities from February to April 2013. The experiences of PWID who were currently or previously on OAT or currently trying to access OAT were analyzed to identify entry and retention barriers encountered. Transcribed data were analyzed using a grounded theory approach. Individual beliefs about OAT, particularly misaligned treatment goals between clients and providers, influenced PWID's treatment seeking behaviors. Multiple programmatic and structural issues, including inconvenient hours and treatment site locations, complicated dosing regimens, inflexible medication dispensing guidelines, and mistreatment by clinic and medical staff also strongly influenced OAT retention. Findings suggest the need for both programmatic and policy-level structural changes such as revising legal regulations covering OAT dispensing, formalizing prescription dosing policies and making OAT more available through other sites, including primary care settings as a way to improve treatment retention. Quality improvement interventions that target treatment settings could also be deployed to overcome healthcare delivery barriers. Additional patient education and medical professional development around establishing realistic treatment goals as well as community awareness campaigns that address the myths and fears associated with OAT can be leveraged to overcome individual, family and community-level barriers.

Challenges to implementing opioid substitution therapy in Ukrainian prisons: Personnel attitudes toward addiction, treatment, and people with HIV/AIDS

BACKGROUND

Ukraine is experiencing one of the most volatile HIV epidemics globally, fueled primarily by people who inject drugs (PWIDs), and a parallel incarceration epidemic. Opioid substitution therapy (OST) is internationally recognized as one of the most effective forms of treatment for opioid dependence and is among the most effective HIV prevention strategies available, yet efforts to adopt it in Ukraine's Criminal Justice System (CJS) have been thwarted.

METHODS

To understand the reluctance of the Ukrainian CJS to adopt OST despite the overwhelming evidence pointing to its health benefits and improved criminal justice outcomes, we conducted the first survey of Ukrainian prison administrative, medical and custodial staff (N=243) attitudes towards addiction in general, OST, and people living with HIV/AIDS (PLWHA) in representative regions of Ukraine.

RESULTS

Results revealed that Ukrainian CJS workers' attitudes toward OST, PLWHA, and drug addiction were universally negative, but differed substantially along geographic and occupational lines. Whereas geographic and cultural proximity to the European Union drove positive attitudes in the west, in the southern region we observed an identifiability effect, as workers who worked directly with prisoners held the most positive attitudes. We also found that knowledge mediated the effect of drug intolerance on OST attitudes.

CONCLUSION

In Ukraine, adoption of OST is more influenced by myths, biases and ideological prejudices than by existing scientific evidence. By elucidating existing attitudes among CJS personnel, this study will help to direct subsequent interventions to address the barriers to implementing evidence-based HIV prevention treatments.

Client and staff experiences of a co-located service for hepatitis C care in opioid substitution treatment settings in New South Wales, Australia

BACKGROUND

Internationally, there are ongoing efforts to increase access to hepatitis C (HCV) assessment and treatment to counter a generally low uptake of treatment among people with a history of injecting drug use. The aim of this qualitative study was to examine client and staff attitudes towards and experience of co-location of HCV and opioid substitution treatment (OST) services.

METHODS

In-depth interviews were conducted with 57 clients and 19 staff from four NSW clinics participating in the Australian ETHOS study.

RESULTS

Client and staff participants typically welcomed integrated treatment, citing issues of convenience, reduced travel time and costs, persistent cues to engagement and immediacy of access to care. Positive attitudes towards the initiative were expressed even by clients who had not engaged with HCV care. Providing co-located care largely avoided the negative, stigmatising or discriminatory experiences that participants reported encountering in settings less familiar with people who use drugs. A minority of client participants expressed concerns about the lack of privacy and/or confidentiality available in the co-located model, preferring to seek HCV care elsewhere.

CONCLUSIONS

The co-location of HCV care in OST clinics was welcomed by the large majority of participants in this study. Besides issues of convenience, the appeal of the co-located service centred on the familiarity of existing relationships between clients and staff in the OST setting. While some clients remained distrustful of OST and chose not to take up HCV care in this setting, the co-located treatment model was overwhelmingly successful amongst both client and staff participants.
