RESUMO
INTRODUCTION: Prison settings represent the highest concentration of prevalent hepatitis C cases in Australia due to the high rates of incarceration among people who inject drugs. Highly effective direct-acting antiviral (DAA) therapies for hepatitis C virus (HCV) infection are available to people incarcerated in Australian prisons. However, multiple challenges to health care implementation in the prison sector present barriers to people in prison reliably accessing hepatitis C testing, treatment, and prevention measures. MAIN RECOMMENDATIONS: This Consensus statement highlights important considerations for the management of hepatitis C in Australian prisons. High coverage testing, scale-up of streamlined DAA treatment pathways, improved coverage of opioid agonist therapy, and implementation and evaluation of regulated provision of prison needle and syringe programs to reduce HCV infection and reinfection are needed. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: The recommendations set current best practice standards in hepatitis C diagnosis, treatment and prevention in the Australian prison sector based on available evidence. Prison-based health services should strive to simplify and improve efficiency in the provision of the hepatitis C care cascade, including strategies such as universal opt-out testing, point-of-care testing, simplified assessment protocols, and earlier confirmation of cure. Optimising hepatitis C management in prisons is essential to prevent long term adverse outcomes for a marginalised population living with HCV. Scale-up of testing and treatment in prisons will make a major contribution towards Australia's efforts to eliminate hepatitis C as a public health threat by 2030.

BACKGROUND: A precipitous decline in health status among people recently released from prison is common. In Victoria, Australia, opioid agonist treatment (OAT) in the community involves frequent contact with primary care, potentially facilitating broader use of primary healthcare services. Among a cohort of men who injected drugs regularly pre-imprisonment, we estimated differences in rates of primary healthcare use and medication dispensation between people who did and did not receive OAT post-release. METHODS: Data came from the Prison and Transition Health Cohort Study. Three-month post-release follow-up interviews were linked with primary care and medication dispensation records. Generalised linear models were fit with one exposure (OAT: none/partial/complete) for 13 outcomes relating to primary healthcare use, pathology testing, and medication dispensation, adjusted for other covariates. Coefficients were reported as adjusted incidence rate ratios (AIRR). RESULTS: Analyses included 255 participants. Compared to no OAT use, both partial and complete OAT use were associated with increased rates of standard (AIRR: 3.02, 95%CI: 1.88-4.86; AIRR: 3.66, 95%CI: 2.57-5.23), extended (AIRR: 2.56, 95%CI: 1.41-4.67; AIRR: 2.55, 95%CI: 1.60-4.07) and mental health-related (AIRR: 2.71, 95%CI: 1.42-5.20; AIRR: 2.27, 95%CI: 1.33-3.87) general practitioner (GP) consultations, total medication (AIRR: 1.88, 95%CI: 1.19-2.98; AIRR: 2.40, 95%CI: 1.71-3.37), benzodiazepine (AIRR: 4.99, 95%CI: 2.81-8.85; AIRR: 8.30, 95%CI: 5.28-13.04) and gabapentinoid (AIRR: 6.78, 95%CI: 3.34-13.77; AIRR: 4.34, 95%CI: 2.37-7.94) dispensations, respectively. Partial OAT use was also associated with increased after-hours GP consultations (AIRR: 4.61, 95%CI: 2.24-9.48) and complete OAT use? with increased pathology utilisation (e.g. haematological, chemical, microbiological or immunological tissue/sample testing; AIRR: 2.30, 95%CI: 1.52-3.48). CONCLUSION: We observed higher rates of primary healthcare use and medication dispensation among people who reported partial and complete OAT use post-release. Findings suggest that access to OAT post-release may have a collateral benefit in supporting broader health service utilisation, underscoring the importance of retention in OAT after release from prison.

BACKGROUND: People recently released from prison engage with emergency healthcare at greater rates than the general population. While retention in opioid agonist treatment (OAT) is associated with substantial reductions in the risk of opioid-related mortality postrelease, it is unknown how OAT affects contact with emergency healthcare. In a cohort of men who injected drugs regularly prior to imprisonment, we described rates of contact with ambulance services and EDs, and their associations with use of OAT, in the 3 months after release from prison. METHODS: Self-report data from a prospective observational cohort of men who regularly injected drugs before a period of sentenced imprisonment, recruited between September 2014 and May 2016, were linked to state-wide ambulance and ED records over a 3-month postrelease period in Victoria, Australia. We used generalised linear models to estimate associations between OAT use (none/interrupted/retained) and contact with ambulance and EDs postrelease, adjusted for other covariates. RESULTS: Among 265 participants, we observed 77 ambulance contacts and 123 ED contacts over a median of 98 days of observation (IQR 87-125 days). Participants who were retained in OAT between prison release and scheduled 3-month postrelease follow-up interviews had lower rates of contact with ambulance (adjusted incidence rate ratio (AIRR) 0.33, 95% CI 0.14 to 0.76) and ED (AIRR 0.43, 95% CI 0.22 to 0.83), compared with participants with no OAT use postrelease. Participants with interrupted OAT use did not differ from those with no OAT use in rates of contact with ambulance or ED. CONCLUSION: We found lower rates of contact with emergency healthcare after release among people retained in OAT, but not among people reporting interrupted OAT use, underscoring the benefits of postrelease OAT retention. Strategies to improve accessibility and support OAT retention after leaving prison are important for men who inject drugs.

To reach World Health Organization elimination targets for hepatitis C, different strategies are needed to reach people who have not yet been diagnosed and treated. In the context of declining treatment initiation rates, innovation in service design and delivery is necessary: testing and treatment needs to be offered to people in non-traditional settings. The community corrections (probation and parole) population is larger than the prison population, which has high prevalence of hepatitis C and-in some countries-established diagnosis and treatment programs. In this Viewpoint we identify a gap in hepatitis C care for people under community correctional supervision, a group who have either never been imprisoned or need continuity of healthcare provided in prison. We propose that offering hepatitis C screening and treatment would benefit this population, and accelerate progress to hepatitis C elimination.
RESUMO
BACKGROUND: To achieve hepatitis C virus (HCV) elimination targets, simplified care engaging people who inject drugs is required. We evaluated whether fingerstick HCV RNA point-of-care testing (PoCT) increased the proportion of clients attending a supervised injecting facility who were tested for hepatitis C. METHODS: Prospective single-arm study with recruitment between 9 November 2020 and 28 January 2021 and follow-up to 31 July 2021. Clients attending the supervised injecting facility were offered HCV RNA testing using the Xpert® HCV Viral Load Fingerstick (Cepheid, Sunnyvale, CA) PoCT. Participants with a positive HCV RNA test were prescribed direct acting antiviral (DAA) therapy. The primary endpoint was the proportion of clients who engaged in HCV RNA PoCT, compared to a historical comparator group when venepuncture-based hepatitis C testing was standard of care. RESULTS: Among 1618 clients who attended the supervised injecting facility during the study period, 228 (14%) engaged in PoCT. This was significantly higher than that observed in the historical comparator group (61/1,775, 3%; p < 0.001). Sixty-five (28%) participants were HCV RNA positive, with 40/65 (62%) receiving their result on the same day as testing. Sixty-one (94%) HCV RNA positive participants were commenced on DAA therapy; 14/61 (23%) started treatment on the same day as diagnosis. There was no difference in the proportion of HCV RNA positive participants commenced on treatment with DAA therapy when compared to the historical comparator group (61/65, 94% vs 22/26, 85%; p = 0.153). However, the median time to treatment initiation was significantly shorter in the PoCT cohort (2 days (IQR 1-20) vs 41 days (IQR 22-76), p < 0.001). Among participants who commenced treatment and had complete follow-up data available, 27/36 (75%) achieved hepatitis C cure. CONCLUSIONS: HCV RNA PoCT led to a significantly higher proportion of clients attending a supervised injecting facility engaging in hepatitis C testing, whilst also reducing the time to treatment initiation.

BACKGROUND AND AIM: Forty percent of new hepatitis B virus (HBV) infections in Australia occur in people who inject drugs (PWID); long-term infection carries the risk of serious liver disease. HBV incidence among Australian PWID has not been measured since the advent of targeted (2001) and adolescent school-based "catch-up" (1998) vaccination programs. We measured HBV incidence and prevalence in a cohort of PWID in Melbourne, Australia and examined demographic and behavioral correlates of exposure and vaccination. METHODS: Community-recruited PWID were surveyed about blood-borne virus risk behaviors and their sera tested for HBV markers approximately three-monthly over three years. Incidence was assessed using prospectively collected data. A cross-sectional design was used to examine prevalence of HBV exposure and vaccination at baseline. Poisson regression was used to identify correlates of HBV exposure and vaccination. RESULTS: At baseline, 33.1% of participants (114/344) had been vaccinated against HBV, 40.4% (139/344) had been exposed (previously or currently infected), and 26.5% (91/344) were susceptible. HBV incidence was 15.7 per 100 person-years. Independent associations with HBV exposure included female gender, South-East Asian ethnicity, drug treatment in the past three months, injecting in prison, and prior exposure to hepatitis C virus. Independent associations with vaccination included being ≤ 25 years old, reporting HBV vaccination, and never having been to prison. CONCLUSIONS: HBV infection continues at high incidence among Australian PWID despite the introduction of free vaccination programs. Innovative methods are needed to encourage PWID to complete HBV vaccination.

BACKGROUND: Retention in opioid agonist treatment (OAT) following release from prison is associated with improved outcomes, however factors associated with post-release OAT discontinuation in Australia are poorly understood. We examined post-release OAT discontinuation in a cohort of men who engaged in approximately monthly injecting drug use (IDU) prior to imprisonment in Victoria, Australia. METHODS: Longitudinal data were used to calculate incidence of first-event post-release OAT discontinuation among men released from prison receiving OAT, and single-event discrete-time survival methods were used to estimate associations with post-release OAT discontinuation. RESULTS: Among 110 participants, 55 OAT discontinuations were observed in the two years post-release, an overall crude incidence rate (IR) of 46 per 100 person-years (PY) (95 % confidence interval [95 %CI]: 36-60 per 100PY). Incidence was greatest between release from prison and first follow-up (IR: 84 per 100PY, 95 %CI: 62-116 per 100PY). Initiating OAT during index imprisonment (versus transitioning from community OAT; adjusted hazard rate [AHR]: 2.17, 95 %CI: 1.14-4.13) and identifying as Aboriginal and/or Torres Strait Islander (AHR: 4.95, 95 %CI: 2.00-12.25) were associated with an increased hazard of OAT discontinuation. CONCLUSION: In a cohort of men with recent histories of IDU released from prison receiving OAT, half reported OAT discontinuation within two years of release from prison, with incidence of discontinuation greatest soon after prison-release. Targeted support for men who initiate OAT during episodes of imprisonment and Aboriginal and/or Torres Strait Islander peoples is necessary to reduce incidence of OAT discontinuation among people at greatest risk of discontinuation.

Following the availability of highly effective direct-acting antivirals (DAAs) to treat hepatitis C infection, the uptake of treatment by people living with hepatitis C rose dramatically in high- and middle-income countries but has since declined. To achieve the World Health Organization's (WHO) 2030 target to eliminate hepatitis C as a public health threat among people who inject drugs, an increase in testing and treatment is required, together with improved coverage of harm reduction interventions. The population that remains to be treated in high- and middle-income countries with high hepatitis C prevalence are among the most socially disadvantaged, including people who inject drugs and are involved in the criminal justice system, a group with disproportionate hepatitis C prevalence, compared with people in the wider community. Imprisonment provides an unrivalled opportunity for screening and treating large numbers of people for hepatitis C, who may not access mainstream health services in the community. Despite some implementation challenges, evidence of the efficacy, acceptability, and cost-effectiveness of in-prison hepatitis treatment programs is increasing worldwide, and evaluations of these programs have demonstrated the capacity for treating people in high numbers. In this Perspective we argue that the scale-up of hepatitis C prevention, testing, and treatment programs in prisons, along with the investigation of new and adapted approaches, is critical to achieving WHO elimination goals in many regions; the Australian experience is highlighted as a case example. We conclude by discussing opportunities to improve access to prevention, testing, and treatment for people in prison and other justice-involved populations, including harnessing the changed practices brought about by the COVID-19 pandemic.

AIMS: To estimate incidence of post-release injecting drug use (IDU) among men who injected drugs before imprisonment and determine factors associated with post-release IDU frequency. DESIGN, SETTING, PARTICIPANTS: Prospective cohort study of men reporting monthly IDU before a period of sentenced imprisonment in Victoria, Australia, recruited between September 2014 and May 2016 (n = 195). MEASUREMENTS: Any post-release IDU and IDU frequency was measured via self-report at 3-month follow-up interview. IDU frequency, measured over the preceding month, was categorised as no IDU, irregular IDU (1-4 days IDU) and regular IDU (≥5 days IDU). Incidence of any IDU was calculated at 3 months post-release. Factors associated with IDU frequency were estimated using ordinal logistic regression. FINDINGS: Most (83%) participants reported post-release IDU (265 per 100 person-years, 95% CI, 227-309); with half (48%) reporting regular IDU, 23% irregular IDU and 29% no IDU in the month preceding follow-up. Poorer psychological well-being at follow-up (General Health Questionnaire [GHQ-12] score; adjusted odds ratio [AOR], 1.18; 95% CI, 1.07-1.29) and post-release unemployment (AOR, 4.57; 95% CI, 1.67-12.49) were associated with increased IDU frequency. Retention in opioid agonist treatment (AOR, 0.49; 95% CI, 0.24-0.98) was associated with reduced IDU frequency. Non-linear (inverted-u) associations between IDU frequency and age (age: AOR, 1.51; 95% CI, 1.17-1.96; age-squared: AOR, 0.99; 95% CI, 0.99-0.99) and pre-imprisonment IDU frequency (pre-imprisonment IDU frequency: AOR, 1.36; 95% CI, 1.15-1.61; pre-imprisonment IDU frequency-squared: AOR, 0.99; 95% CI, 0.99-0.99) were found, with odds peaking at age 39 and 19 days IDU, respectively. Longer baseline sentence length was associated with reduced odds of irregular and regular IDU (AOR, 0.99; 95% CI, 0.99-0.99). CONCLUSION: Among Australian men who inject drugs before imprisonment, resumption of injecting drug use after release from prison appears to be common, with imprisonment seeming to have little impact on reducing injecting drug use behaviour.

INTRODUCTION AND AIMS: Once involved in the criminal justice system, people who inject drugs (PWID) have a high probability of multiple system encounters. Imprisonment typically fails to rehabilitate PWID, who upon return to the community are at considerable risk of returning to injecting drug use (IDU) and poor health and social outcomes. We examined the effect of IDU resumption, and a suite of other sociodemographic, criminogenic, health and behavioural indicators, on the timing of reincarceration among adults with a history of IDU following release from prison. DESIGN AND METHODS: Structured interviews were conducted with 561 PWID in Queensland, Australia prior to release from prison and approximately 1, 3 and 6 months post-release. Data were linked prospectively with correctional records and the National Death Index. Data collected at multiple time-points were treated as time-varying covariates. Kaplan-Meier survival estimates and Cox proportional hazards models were used to estimate the rate and hazards of reincarceration. RESULTS: Sixty-eight percent of participants (n = 350) were reincarcerated over a combined observation time of 1043.5 years, representing a rate of 33.5 per 100 person-years (95% confidence interval [CI] 30.2-37.2). Time-invariant predictors of reincarceration in PWID were: male gender (adjusted hazard ratio [AHR] = 1.62, 95% CI 1.19-2.21), older age at release (AHR = 0.97, 95% CI 0.95-1.00), previous adult (AHR = 2.00, 95% CI 1.41-2.84) or juvenile (AHR = 1.78, 95% CI 1.27-2.49) imprisonment, shorter imprisonment (≤90 days vs. >365 days, AHR = 2.09, 95% CI 1.30-3.34), release on parole (AHR = 2.29, 95% CI 1.82-2.88) and drug-related sentence (AHR = 1.84, 95% CI 1.34-2.53). Time-varying predictors included resumption of IDU (AHR = 2.04, 95% CI 1.60-2.61), unemployment (AHR = 1.53, 95% CI 1.07-2.19) and low perceived social support (AHR = 1.41, 95% CI 1.05-1.90). Very-high psychological distress at the most recent interview was protective against reincarceration (AHR = 0.65, 95% CI 0.44-0.95). DISCUSSION AND CONCLUSIONS: Efforts to prevent resumption of IDU and address disadvantage, social inclusion and health service access in ex-prisoners through the scale-up and integration of prison-based and post-release interventions are likely to reap both public health and criminal justice benefits.

OBJECTIVES: Testing is the first step in treatment and care for blood-borne viruses (BBVs) and sexually transmitted infections (STIs). As new treatments for viral hepatitis emerge, it is important to document effective models for BBV/STI testing. A nurse-led intervention was implemented across three prisons in Victoria to improve BBV/STI testing. We evaluated the impact of the intervention on BBV/STI testing rates and hepatitis B (HBV) vaccination for reception prisoners. METHODS: BBV/STI testing and HBV vaccination data were collected from the medical files of 100 consecutive reception prisoners at three prisons (n=300) prior to and after the intervention was implemented. RESULTS: BBV testing increased significantly from 21% of prisoners to 62% post-intervention. Testing for some STIs increased significantly, but remained low: 5% to 17% for chlamydia and 1% to 5% for gonorrhoea. HBV vaccination increased significantly from 2% to 19%. CONCLUSIONS: The nurse-led intervention resulted in substantially increased testing and vaccination, demonstrating the benefits of a concerted effort to improve BBV and STI management in correctional settings. IMPLICATIONS: The availability of new treatments for hepatitis C has precipitated expansion of treatment in prisons. Improving the testing rate of prisoners, the first step in the treatment cascade, will maximise the benefits.
