Achieving HCV micro-elimination in rural communities

Pharmacy-based screening program to detect hepatitis C in 'baby-boomer' cohorts in western Canada

Background

The estimated prevalence of hepatitis C virus (HCV) in Canada is approximately 1.0%. However, the number of individuals living with HCV but unaware of it is estimated to be 30%-44%. Increased screening programs that are accessible, effective, and feasible are important to ensure treatment and meet WHO elimination goals. We implemented an HCV point of care test (POCT) program in community pharmacies to examine the effectiveness and feasibility in screening.

Methods

Twenty two London Drugs pharmacies in British Columbia and Alberta implemented an HCV POC screening program using OraQuick rapid antibody tests. Consenting patients filled out a 10-question screening questionnaire to examine risk factors. The participants then were tested using the POCT. While waiting for the test (20 minutes), patients were educated on HCV and treatment options.

Results

Three hundred seventy-one participants underwent HCV screening. The most common HCV risk factor was being born between 1945 and 1975 (baby boomer) (93% of cohort), while the second most common was having a tattoo or body piercing (22%). Seven people (2%) tested positive; four were HCV-RNA PCR-positive and were treated, whereas the PCR status of three was unknown as they were lost to follow-up or not tested.

Conclusions

Pharmacy-based POCT was shown to be effective and feasible in the western Canadian context, especially for baby boomers. Sustainable funding for pharmacy screening programs may be considered nationwide to identify HCV-infected persons and help meet elimination goals.

Treating people where they are: Nurse-led micro-elimination of hepatitis C in supported housing sites for networks of people who inject drugs in Victoria, Canada

To achieve the World Health Organization's goal of eliminating hepatitis C (HCV) by 2030 requires enhanced HCV testing and treatment among people who use drugs (PWUD). Micro-elimination of HCV is a strategy to target HCV testing and treatment efforts to specific segments of the population. From February to December 2018 nurses initiated a "seek & treat" micro-elimination approach, increasing outreach and removing barriers to accessing HCV treatment in a clinic setting by testing and treating individuals, including PWUD, where they live. The aim of this study was to evaluate the proportion of clients with HCV antibodies and HCV RNA and the response to direct acting agent (DAA therapy) among people who live at or have social connections to local supportive housing sites through this nurse-led micro-elimination project in Victoria, Canada. A chart review of electronic medical records and case management documentation was used to collect relevant data of participants treated with DAA therapy, identified through specific housing site testing and outreach interventions. In total, 180 people were tested for HCV antibodies, 72 (40%) were antibody positive: 51 (28%) were RNA positive, 13 (7%) had spontaneously cleared and 8 (4%) had been previously treated. Of the 51 that were currently living with HCV, 43 people were started on treatment, 39 have achieved sustained virologic response (SVR). By providing treatment to clients in their homes and with their friends, clinicians have been able to treat clients, including those with limited contact with the health care system.

ECHO+: Improving access to hepatitis C care within Indigenous communities in Alberta, Canada

BACKGROUND

Indigenous populations experience higher rates of hepatitis C virus (HCV) infections in Canada. The Extension for Community Health Outcomes+ (ECHO+) telehealth model was implemented in Alberta to support HCV screening and treatment, using Zoom technology to support Indigenous patient access to specialist care closer to home. Our goal was to expand this program to more Indigenous communities in Alberta, using various Indigenous-led or co-designed methods.

METHODS

The ECHO+ team implemented a Two-Eyed Seeing framework, incorporating Indigenous wholistic approaches alongside Western treatment. This approach works with principles of respect, reciprocity, and relationality. The ECHO+ team identified Indigenous-specific challenges, including access to liver specialist care, HCV awareness, stigma, barriers to screening and lack of culturally relevant approaches.

RESULTS

Access to HCV care via this program significantly increased HCV antiviral use in the past 5 years. Key lessons learned include Indigenous-led relationship building and development of project outputs in response to community needs influences impact and increases relevant changes increasing access to HCV care. Implementation of ECHO+ was carried out through biweekly telehealth sessions, problem solving in partnership with Indigenous communities, increased HCV awareness, and flexibility resulting from the impacts of COVID-19.

CONCLUSION

Improving Indigenous patient lives and reducing inequity requires supporting local primary health care providers to create and sustain integrated HCV prevention, diagnosis, treatment, and support services within a culturally safe and reciprocal model. ECHO+ uses telehealth and culturally appropriate methodology and interventions alongside multiple stakeholder collaborations to improve health outcomes for HCV.
