Eradicating hepatitis C from the New South Wales prison system

In October 2016, we achieved the eradication and control of hepatitis C virus (HCV) in a New South Wales correctional centre, which we believe to be a first of its kind in NSW.

HCV prevalence in NSW prisons is 30–40 times higher than in the community, where prevalence is about 1%.1,2 Elevated risk of HCV infection is associated with the high proportion of prisoners who have injected drugs, the rate of injecting in prison, and restricted or limited access to bleach and needle and syringe programs.3

The Justice Health and Forensic Mental Health Network (the Network) is responsible for health care in the NSW forensic mental health and criminal justice systems. The availability of direct-acting antivirals on the Pharmaceutical Benefits Scheme in March 20164 created an opportunity for the Network to cure all patients with HCV infection in one prison.

The Compulsory Drug Treatment Program (CDTP) is run at the Compulsory Drug Treatment Correctional Centre — a stand-alone prison with a stable sentenced inmate population, where patients with repeat drug-related charges participate in comprehensive drug treatment and rehabilitation. Patients at this correctional centre have longer sentences than those in other centres, which allowed for the full course of treatment.

The Network, Corrective Services NSW and Hepatitis NSW formed a partnership to ensure that patients were able to access health centres, have their medication scripted and administered, could undertake monitoring and were supported through the Network’s established nurse-led model of care.5 All 58 patients in the CDTP were offered screening, and 54 patients with risk factors were screened; of these, 18 patients had chronic HCV infection. After further work-up, including liver elastography to measure fibrosis, all patients were concurrently commenced on treatment. Of the remaining four patients who were not screened, all had recent negative HCV pathology results.

Three months after the treatment, 15 patients achieved sustained virological response equating to cure of their chronic HCV infection, and three patients were released before final assessment.6 Concurrent treatment commencement with the direct-acting antivirals was recognised as an innovative measure in reducing re-infection, in conjunction with the more common practices of harm minimisation education and use of the hospital-grade disinfectant for general cleaning purposes offered by Corrective Services NSW to all incarcerated people.

Throughout the course of the project, two new patients were admitted, screened, and returned negative HCV pathology results. A proactive screening approach with patient consent was adopted to ensure that new cases were able to be identified and treated to maintain elimination.

Maintaining a prison HCV-free may mean that patients have to take some responsibility with regard to sharing needles with new inmates. A peer education approach is being developed to increase patients’ ownership of a prison’s HCV-free status. The CDTP treatment model, combined with ongoing screening of new admissions, is an innovative approach for eliminating HCV, and is considered suitable for adoption in similar-sized prisons across Australia. The Network is currently rolling out this approach within NSW.
