Pharmacy-led hepatitis C treatment pathways to help ensure elimination

A randomized controlled trial for a peer-facilitated telemedicine hepatitis c treatment intervention for people who use drugs in rural communities: study protocol for the "peer tele-HCV" study

BACKGROUND

Hepatitis C virus (HCV) transmission is primarily driven by injection drug use, and acute HCV infection rates are increased in rural communities with substantial barriers to care. Treatment of HCV in persons who use drugs (PWUD) is cost effective, decreases high risk behaviors and HCV transmission, and achieves high rates of treatment completion and sustained viral response. Adapting HCV care delivery to utilize peer support specialists, telemedicine technology, and streamlined testing and treatment strategies can better reach rural populations living with HCV.

METHODS

This is an open label, two-arm, non-blinded, randomized controlled trial designed to test the superiority of peer-facilitated and streamlined telemedicine HCV care (peer tele-HCV) compared to enhanced usual care (EUC) among PWUD in rural Oregon. In the intervention arm, peers conduct HCV screening in the community, facilitate pretreatment evaluation and linkage to telemedicine hepatitis C treatment providers, and support participants in HCV medication adherence. For participants assigned to EUC, peers facilitate pretreatment evaluation and referral to community-based treatment providers. The primary outcome is sustained virologic response at 12 weeks post treatment (SVR12). Secondary outcomes include: (1) HCV treatment initiation, (2) HCV treatment completion, (3) engagement with harm reduction resources, (4) rates of substance use, and (5) engagement in addiction treatment resources. The primary and secondary outcomes are analyzed using intention-to-treat (ITT) comparisons between telemedicine and EUC. A qualitative analysis will assess patient, peer, and clinician experiences of peer-facilitated telemedicine hepatitis C treatment.

DISCUSSION

This study uses a novel peer-based telemedicine delivery model with streamlined testing protocols to improve access to HCV treatment in rural communities with high rates of injection drug use and ongoing disease transmission. We hypothesize that the peer tele-HCV model will increase treatment initiation, treatment completion, SVR12 rates, and engagement with harm reduction services compared to EUC. Trial registration This trial has been registered with ClinicalTrials.gov (clinicaltrials.gov NCT04798521).

Directly observed hepatitis C treatment with opioid substitution therapy in community pharmacies: A qualitative study

BACKGROUND

The hepatitis C virus (HCV) will only be eliminated through successful engagement with people who inject drugs (PWID), however some of this population experience socioeconomic and individual issues that can lead to poor HCV treatment adherence. A key sub-group of (PWID) are those who receive opioid substitution therapy (OST). In Australia, OST is most often delivered under direct supervision by a community pharmacist every day or multiple times a week. This regular interaction could be an ideal opportunity to enhance direct-acting antiviral (DAA) treatment adherence under directly observed therapy (DOT) by the pharmacist.

AIM

The aim of this study was to explore the perspectives of OST patients with a lived experience of HCV to understand whether or not dispensing DAAs in the same way as, or simultaneously with OST would benefit HCV treatment.

METHODS

Data collection occurred from June to August 2017. Semi-structured interviews were conducted with a sample of PWID living with HCV and on OST programs (n = 12) in Melbourne, Australia. Interviews were voice recorded and transcribed in verbatim. Interpretive phenomenology guided analysis of the data.

RESULTS

Themes reported by participants that provide insight into the suitability of DOT of DAAs include: Adherence and non-adherence to DAA treatment; Mixed views towards DOT of DAAs; Experiences and perceptions of OST providers; and Perceived stigma in the pharmacy.

CONCLUSIONS

Community pharmacies offering OST may be an effective place for DOT of HCV treatment, but is likely only to benefit people who face significant challenges to adherence. We suggest that a positive pharmacist-patient relationship, high OST adherence, and commitment to reducing stigma in the pharmacy would be necessary for the intervention to be effective. Further research is needed to evaluate the expanded-role of community pharmacies in improving DAA adherence and eliminating HCV.
