Barriers and facilitators to hepatitis C (HCV) screening and treatment-a description of prisoners' perspective

Development of an evidence-based hepatitis C education program to enhance public health literacy in the Australian prison sector: The Hepatitis in Prisons Education program (HepPEd)

BACKGROUND

Australia's prisons have a high chronic hepatitis C (HCV) prevalence (8 %). Antiviral therapies and prison-based hepatitis services are available, but only a minority of those eligible are being treated. Improving the HCV public health literacy of the prison sector via targeted education may overcome key barriers to scale-up treatment. This paper describes the: i) HCV public health literacy of the prison setting; ii) barriers and solutions for HCV education and service engagement; iii) HCV education program co-design and development processes; and iv) HepPEd resources.

METHODS

A national needs assessment was conducted to analyse the HCV public health literacy of the target audience groups in the prisons (healthcare providers; custodial officers; people in prison) to inform development of a prison-specific HCV education program (HepPEd). Structured interviews were conducted with key informants (n = 40). Three National Steering Committees, one for each target group, were convened to co-design and develop HepPEd.

RESULTS

Only healthcare providers involved with hepatitis care were considered to have 'good' to 'very good' HCV health literacy (including knowledge, attitudes, and capabilities), with all other groups considered less favourably. Key barriers identified included being time poor (healthcare providers), poor motivation (custodial officers) and stigma (people in prison). Peer education delivery was considered a key facilitator for custodial officers and people in prison. A suite of multi-modal resources addressing the perceived gaps in HCV health literacy was developed, with a broad theme of 'Let's talk about hep C'. Delivery of HepPEd was designed to overcome key barriers and utilise facilitators for each group.

CONCLUSIONS

Significant gaps in HCV health literacy were perceived amongst the target audience groups. The comprehensive co-design and development processes utilised in HepPEd suggest the program will be well-placed to improve the HCV public health literacy of the prison sector and thereby enhance HCV testing and treatment rates amongst people in prison.

Barriers to access to hepatitis C treatment with direct-acting antivirals in people who inject drugs in the community setting

Barriers to access to hepatitis C treatment with direct-acting antivirals in people who inject drugs in the community setting. Qualitative study with prison population. Hepatitis C (HCV) treatments with direct-acting antiviral therapy (DAA) are an easy and effective option among people who inject drugs (PWID). However, difficulties in accessing and monitoring treatment in community services and dropouts on release from prison are detected among PWID. For this reason, the aim of the study is to know the access barriers in the diagnosis and treatment of HCV in community health services. An exploratory qualitative study was carried out through semi-structured interviews with 33 PWID recruited in a pre-trial detention prison in Barcelona. The information obtained was analysed using grounded theory. Among PWID sub-population entering prison, personal barriers are related to intense drug use, lack of interest and ignorance of HCV infection and treatment, as well as being in a situation of social exclusion. In relation to health providers, they reported receiving little information, the existence of language barriers in migrants, not receiving screening and treatment proposals, and having poor interactions with some professionals. Systemic barriers were expressed related to the health system circuit being complicated, perceiving little comprehensive care and lack of community support. It is recommended to intensify prevention and treatment campaigns, promoting drug substitution programmes than current ones, improve health education, make the diagnosis and treatment process more flexible, and promote social policies and holistic care for greater coverage of the needs of PWID.

Factors associated with prior completion of colorectal cancer and hepatitis C virus screenings among community health center patients: a cross-sectional study to inform a multi-behavioral educational intervention

BACKGROUND

Colorectal cancer (CRC) and liver cancer are two of the leading causes of cancer death in the United States and persistent disparities in CRC and liver cancer incidence and outcomes exist. Chronic hepatitis C virus (HCV) infection is one of the main contributors to liver cancer. Effective screening for both CRC and HCV exist and are recommended for individuals based upon age, regardless of gender or sex assigned at birth. Recommendations for both screening behaviors have been recently updated. However, screening rates for both CRC and HCV are suboptimal. Targeting adoption of multiple screening behaviors has the potential to reduce cancer mortality and disparities.

OBJECTIVE

To examine psychosocial factors associated with completion of CRC and HCV screenings in order to inform a multi-behavioral educational intervention that pairs CRC and HCV screening information.

METHODS

A cross-sectional survey was conducted with participants (N = 50) recruited at two community health centers in Florida (United States). Kruskal-Wallis and Fisher's exact tests were used to examine associations between completion of both CRC and HCV screening, CRC and HCV knowledge, Preventive Health Model constructs (e.g., salience and coherence, response efficacy, social influence), and sociodemographic variables.

RESULTS

Most participants were White (84%), female (56%), insured (80%), and reported a household income of $25,000 or less (53%). 30% reported ever previously completing both CRC and HCV screenings. Prior completion of both screening behaviors was associated with higher educational attainment (p = .014), having health insurance (p = .022), being U.S.-born (p = .043), and higher salience and coherence scores for CRC (p = .040) and HCV (p = .004).

CONCLUSIONS

Findings demonstrate limited uptake of both CRC and HCV screenings among adults born between 1945 and 1965. Uptake was associated with multiple sociodemographic factors and health beliefs related to salience and coherence. Salience and coherence are modifiable factors associated with completion of both screening tests, suggesting the importance of incorporating these health beliefs in a multi-behavioral cancer education intervention. Additionally, health providers could simultaneously recommend and order CRC and HCV screening to improve uptake among this age cohort.

The Efficacy of On-Site Integration Screening and Microelimination Programs for Chronic Hepatitis C in a Detection Center: A Comparison of the Treatment Outcomes and Characteristics of Incarcerated Patients and Outpatients

We aimed to analyze the different patient characteristics and treatment outcomes (such as sustained viral response, SVR) between incarcerated patients with chronic hepatitis C (CHC) and those with CHC from the outpatient department through an on-site integrated screening and microelimination program in a detection center. In this retrospective study, which ran from May 2021 to April 2022, we included 32 consenting male prisoners aged at least 20 years who were willing to participate in the study. Members of the control group (who received DAAs in an outpatient setting) were selected from the treated CHC patient databank of individuals who received DAA regimens at Chi Mei Hospital between January 2021 and December 2022. The patients in the two groups did not differ significantly in terms of age, FIB-4 score, HCV RNA, HBV coinfection, hemogram findings, coagulation profiles, and renal function tests. However, the patients in the incarcerated group had a significantly different genotype distribution compared to the control group, significantly lower liver enzyme levels, and higher albumin and bilirubin levels compared to those in the control group. The rate of SVR to DAA treatment obtained among incarcerated patients did not differ significantly from that obtained among patients in the control group. Loss to follow-up (for several reasons) is a major reason for treatment discontinuation among these patients.

Determining reinfection rates by hepatitis C testing interval among key populations: A systematic review and meta-analysis

BACKGROUND & AIMS

Detecting hepatitis C virus (HCV) reinfection among key populations helps prevent ongoing transmission. This systematic review aims to determine the association between different testing intervals during post-SVR follow-up on the detection of HCV reinfection among highest risk populations.

METHODS

We searched electronic databases between January 2014 and February 2023 for studies that tested individuals at risk for HCV reinfection at discrete testing intervals and reported HCV reinfection incidence among key populations. Pooled estimates of reinfection incidence were calculated by population and testing frequency using random-effects meta-analysis.

RESULTS

Forty-one single-armed observational studies (9453 individuals) were included. Thirty-eight studies (8931 individuals) reported HCV reinfection incidence rate and were included in meta-analyses. The overall pooled estimate of HCV reinfection incidence rate was 4.13 per 100 per person-years (py) (95% confidence interval [CI]: 3.45-4.81). The pooled incidence estimate among people who inject drugs (PWID) was 2.84 per 100 py (95% CI: 2.19-3.50), among men who have sex with men (MSM) 7.37 per 100 py (95% CI: 5.09-9.65) and among people in custodial settings 7.23 per 100 py (95% CI: 2.13-16.59). The pooled incidence estimate for studies reporting a testing interval of ≤6 months (4.26 per 100 py; 95% CI: 2.86-5.65) was higher than studies reporting testing intervals >6 months (5.19 per 100 py; 95% CI: 3.92-6.46).

CONCLUSIONS

HCV reinfection incidence was highest in studies of MSM and did not appear to change with retesting interval. Shorter testing intervals are likely to identify more reinfections, help prevent onward transmission where treatment is available and enable progress towards global HCV elimination, but additional comparative studies are required.

Creating a Longitudinal HCV Care Cascade for Persons With HIV/HCV Coinfection in Selected HIV Clinics Using Data to Care Methods

Highly effective direct-acting antiviral (DAA) treatments for hepatitis C have led to strategic goals promoting hepatitis C virus (HCV) cure particularly in focus populations including persons with HIV/HCV coinfection. Implementing treatment more broadly requires both clinic-level and public health approaches such as those inherent in Data to Care (D2C) originally developed to improve the treatment cascade for persons with HIV (PWH). We used D2C methods to characterize and improve HCV treatment for persons with HIV/HCV coinfection among 11 HIV clinics in Connecticut cities with high PWH prevalence. Providers who were local champions in HCV treatment were recruited to participate along with clinic data staff and were key to quality improvement via practice transformation. We developed a methodology whereby clinic-generated lists of PWH receiving care from 2009 to 2018 were matched by CT Department of Public Health (DPH) against the state-wide HCV surveillance system. The resultant coinfection list was reviewed by clinical staff who designated HCV treatment status, enabling creation of individual clinic-level HCV treatment cascades. Data from DPH, especially current residency and deaths, enabled better characterization and allowed for refinement of longitudinal cascades. There were 1,496 patients with HIV/HCV coinfection. Sustained virologic response (SVR) rates varied by clinic (range, 44%-100%) with an aggregate SVR rate of 71% in September 2020. SVR rates improved during the project through a combination of increased treatment initiation/completion as well as data clean-up including serial updates of patient treatment status. Lack of treatment initiation was associated with being female (odds ratio [OR] = 2.18) and not having HIV viral suppression (OR = 3.24).

Investigating rates and risk factors for hepatitis C virus reinfection in people receiving antiviral treatment in England

England has committed to the World Health Organization target to eliminate hepatitis C virus (HCV) as a public threat by the year 2030. Given successful treatments for HCV in recent years, it is unclear whether HCV reinfection will impact England's ability to achieve HCV elimination. We aimed to estimate the HCV reinfection rate among a cohort of patients receiving antiviral treatment using available surveillance data. Linkage between a treatment dataset from 2015 to 2019 and an HCV RNA testing dataset were used to identify people who experienced reinfection using three criteria. A Cox proportional hazards model was used to determine risk factors associated with HCV reinfection among a cohort who received treatment and had follow-up HCV RNA testing. The reinfection rate among those receiving HCV treatment was 7.91 per 100 person-years (PYs, 95% confidence interval (CI) 7.37-8.49) and highest among current injecting drug users (22.55 per 100 PYs, 95% CI 19.98-25.46) and people who had been in prison (20.42 per 100 PYs, 95% CI 17.21-24.24). In the adjusted model, women had a significantly reduced risk of reinfection. Being of younger age, current injecting drug users, and receipt of first treatment in prison were each significantly associated with increased risk of reinfection. Two-fifths of those with reinfection (43%, n = 329/767) were linked to treatment after reinfection, and of those starting treatment, three quarters (75%, n = 222/296) achieved a sustained virologic response. Guidance for testing groups at risk of reinfection and harm reduction strategies to minimize transmission should be implemented if England is to achieve HCV elimination targets.

Consensus recommendations on the management of hepatitis C in Australia's prisons

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.

Statewide Assessment of the Hepatitis C Virus Care Cascade for Incarcerated Persons in Vermont

OBJECTIVES

Incarcerated persons in the United States have a high burden of hepatitis C virus (HCV) infection. This study assessed the impact of a statewide effort in Vermont to treat HCV in this group.

METHODS

We performed a retrospective, observational cohort study of all HCV-infected persons who were imprisoned in Vermont during the 19-month study period (December 2018-June 2020). The cascade of care comprised opt-out HCV screening, full access to direct-acting antiviral treatment (without hepatic fibrosis-based treatment restrictions), HCV specialist involvement, and medication-assisted treatment for patients with opioid use disorder. The primary outcome was sustained virologic response at 12 weeks after treatment completion (SVR12).

RESULTS

The study included 217 HCV-infected patients; the median age was 35 years (range, 18-73 years), 89% were male, 76% had opioid use disorder, 67% had a psychiatric comorbidity, and 9% had cirrhosis. Of the 217 patients, 98% had a liver fibrosis assessment, 59% started direct-acting antiviral treatment, 55% completed direct-acting antiviral treatment, and 51% achieved documented SVR12. Of the 129 HCV-infected persons who started direct-acting antiviral treatment, 92% completed therapy and 86% achieved documented SVR12. Psychiatric comorbidity was not significantly associated with achieving SVR12 (odds ratio = 0.67; 95% CI, 0.27-1.65; P = .38), nor was receiving medication-assisted treatment for patients with opioid use disorder (odds ratio = 1.45; 95% CI, 0.62-2.56; P = .45).

CONCLUSIONS

This study reports the highest SVR12 rate achieved in a state incarcerated population to date. HCV treatment in incarcerated populations is a practical and efficacious strategy that should serve a foundational role in HCV elimination.

Cancer screening in prisons: lessons for health providers

BACKGROUND

Lifestyle factors place those who experience incarceration at increased risk of morbidity and mortality from a range of preventable diseases, including cancer.

METHODS

Two nurses were employed for a period of 6months to facilitate bowel and breast cancer screening of prisoners across four correctional centres in Queensland. We identify factors impacting on cancer screening in prisons and document the outcomes for those screened.

RESULTS

Both screening programs produced a positivity rate of ∼17% in those screened, with 23 individuals returning a positive faecal occult blood test and five women requiring further investigations following breast screening. At 3months postscreening, all of the positive cases had been referred for further investigations. It is likely that the screening programs were instrumental in preventing morbidity (and mortality) in the subgroup with positive test results.

CONCLUSIONS

Cancer screening within the prison environment presents a number of challenges. Intervention at the individual and systems level is required to ensure prisoners can access a standard of care equal to that provided in the community.

Perceptions Towards HCV Treatment with Direct Acting Antivirals (DAAs): A Qualitative Analysis with Persons with HIV/HCV Co-infection Who Delay or Refuse Treatment

In the United States, approximately 25% of people with HIV (PWH) are co-infected with hepatitis C (HCV). Since 2014, highly effective and well-tolerated direct-acting antivirals (DAAs) have revolutionized HCV treatment. Uptake of DAAs by people with HIV/HCV co-infection has improved but remains suboptimal due to system, provider, and patient-level barriers. To explore patient-level issues by better understanding their attitudes towards DAA treatment, we conducted qualitative interviews with 21 persons with HIV/HCV co-infection who did not consent to DAA treatment or delayed treatment for at least 1 year after diagnosis. We found PWH perceived DAA treatment barriers and facilitators on multiple levels of the social-ecological environment: the individual (HCV disease and treatment literacy), interpersonal (peer influence), institutional (media and healthcare provider relationship), and structural levels (treatment cost and adherence support). Recommendations to improve DAA treatment uptake include HCV-treatment adherence support, HCV disease and treatment literacy training (particularly for substance use and DAA treatment interactions), and encouraging PWH who have successfully completed DAA treatment to speak with their peers.

A Cross-Sectional, Retrospective Evaluation of Opt-Out Sexually Transmitted Infection Screening at Admission in a Short-Term Correctional Facility in Alberta, Canada

Incarcerated populations experience higher rates of sexually transmitted infections (STIs) than the general population, alongside inconsistent testing strategies. In response, universal opt-out STIs (chlamydia, gonorrhea, syphilis, and HIV) screening was implemented at admission in a short-term correctional facility in Alberta, Canada, for individuals ≤35 years. A cross-sectional, retrospective evaluation of testing outcomes between March 2018 and February 2020 was completed. Descriptive statistics were used to stratify STIs by gender, age group, and date for univariate analysis. Despite low uptake (31.2%), opt-out screening resulted in high positivity rates (14.9%, 10.8%, 29.5%, and 0.3%, respectively) and treatment completion (93.7%) while capturing a high proportion (52.6%) of asymptomatic cases. Opt-out screening at admission is feasible and can improve STI testing in high-risk individuals experiencing incarceration in Canada.

Identifying barriers and enablers to opt-out hepatitis C virus screening in provincial prisons in Quebec, Canada: A multilevel, multi-theory informed qualitative study with correctional and healthcare professional stakeholders

BACKGROUND

Diffuse implementation of hepatitis C virus (HCV) treatment is dependent on universal screening for HCV, but screening strategies are heterogenous across prisons in the province of Quebec (Canada). We sought to identify barriers and enablers to universal opt-out HCV screening and to describe the multisectoral decision-making processes related to HCV screening in Quebec provincial prisons.

METHODS

A multilevel, multi-theory informed qualitative descriptive approach was used to conduct semi-structured interviews. Interview guides and analyses with correctional stakeholders were informed by the Consolidated Framework for Implementation Research (CFIR) and those with healthcare professionals (HCPs) were based on the Theoretical Domains Framework (TDF). Directed content analysis was used to identify domains within CFIR and TDF reflecting barriers and enablers to opt-out HCV screening.

RESULTS

Sixteen interviews (correctional stakeholders: n = 8; HCPs: n = 8) were conducted in April-May 2021. Twelve CFIR constructs were identified as barriers, seven as enablers, and two as neutral factors for the implementation of opt-out HCV screening. Correctional stakeholders underscored the need for political will (construct: external policy and incentives), highlighted limited resources (construct: available resources), and expressed concerns for the lack of consideration of implementation issues (constructs: trialability, planning). Six TDF domains were identified among HCPs as relevant to the implementation of opt-out HCV screening: beliefs about consequences (mixed = enablers and barriers), environmental context and resources (barrier), social influences (barrier), optimism (mixed), emotions (mixed), and behavioural regulation (barrier). The decision-making processes vis-à-vis HCV care in Quebec correctional settings were found to be hierarchical and complex.

CONCLUSIONS

The use of CFIR and TDF was helpful in identifying barriers and enablers to HCV screening at multiple levels for people incarcerated in Quebec provincial prisons. Going forward, several political, structural, and organizational factors should be addressed through the engagement of stakeholders and people with lived experience of incarceration.

Investigating the sociodemographic and behavioural factors associated with hepatitis C virus testing amongst people who inject drugs in England, Wales and Northern Ireland: A quantitative cross-sectional analysis

BACKGROUND

Hepatitis C virus (HCV) transmission in the UK is driven by injecting drug use. We explore HCV testing uptake amongst people who inject drugs (PWID) in England, Wales and Northern Ireland, and identify factors associated with i) ever having an HCV test amongst people who have ever injected drugs, and ii) recently having an HCV test (within the current or previous year) amongst people who currently inject drugs (reported injecting drugs within the last year).

METHODS

We analysed data from the 2019 'Unlinked Anonymous Monitoring Survey' of PWID, using logistic regression.

RESULTS

Of 3,127 PWID, 2,065 reported injecting drugs within the last year. Most (86.7%) PWID had a lifetime history of HCV testing. In multivariable analysis, higher odds of ever testing were associated with: female sex (aOR=1.54; 95%CI 1.11-2.14), injecting duration ≥3 years (aOR=2.94; 95%CI 2.13-4.05), ever receiving used needles/syringes (aOR=1.74; 95%CI 1.29-2.36), ever being on opioid agonist treatment (aOR=2.91; 95%CI 2.01-4.21), ever being imprisoned (aOR=1.86; 95%CI 1.40-2.48) and ever being homeless (aOR=1.54; 95%CI 1.14-2.07). Amongst PWID who had injected drugs within the last year, 49.9% had recently undertaken an HCV test. After adjustment, factors associated with higher odds of undertaking a recent HCV test included: injecting crack in the last year (aOR=1.29; 95%CI 1.03-1.61), experiencing a non-fatal overdose in the last year (aOR=1.39; 95%CI 1.05-1.85), ever being on opioid agonist treatment (aOR=1.48; 95%CI 0.97-2.25), receiving HCV information in the last year (aOR=1.99; 95%CI 1.49-2.65) and using a healthcare service in the last year (aOR=1.80; 95%CI 1.21-2.67).

CONCLUSION

Results suggest that PWID who have experienced homelessness and incarceration - amongst the most vulnerable and marginalised in the PWID population - are engaging with HCV testing, but overall there remain missed testing opportunities. Recent initiates to injecting have highest HCV infection risk but lower odds of testing, and peer-education may help target this group.

Real-life experience of hepatitis C treatment in a Spanish prison

OBJECTIVE

Hepatitis C virus (HCV) infection is a major public health problem that causes multiple comorbidities. People in prisons who inject intravenous drugs are at increased risk of HCV infection, and HCV infection is 15-fold more prevalent among prisoners compared with the community. The objective of this study was to analyse the clinical and epidemiological characteristics of residents of a Spanish prison with HCV infection who received antiviral treatment.

METHODS

An observational, descriptive and retrospective study was performed. All patients with HCV infection diagnosed or followed up in an Infectious Diseases attached to a penitentiary were included in this study.

RESULTS

Of 81 patients analysed, sixty-nine (83.1%) patients were male. The mean age was 50.1 (SD8.8) years, and 70% of the inmates had a history of injection drug use. Coinfection with HIV was detected in 30%. In up to 25% of the sample, there were data on chronic liver disease in the degree of liver cirrhosis. The diagnosis of HCV infection had been made more than 15 years earlier in 28% of those studied. Decompensations from liver disease, hepatocellular carcinoma, or hospital admissions were exceptional. Most of the inmates with HCV accepted treatment, and approximately 94% of the patients who completed treatment achieved a sustained virological response without interactions or complications of interest.

CONCLUSIONS

The availability of direct-acting antivirals and their exceptional side effects constitute an opportunity to reduce the burden of HCV infection in Spain, particularly in these high-risk populations.

A Global Systematic Review of Hepatitis C Elimination Efforts through Micro-Elimination

Microelimination targets specific subpopulations and/or geographic settings for hepatitis C virus (HCV) elimination. This review reports on global HCV microelimination literature published from 2013 to 2020. Data were extracted from publications to report a score based on the four key components defining microelimination. Sustained virologic response (SVR) and treatment initiation proportions were calculated for each manuscript and grouped means of these estimates were compared depending on microelimination score and care setting. A total of 83% of the studies were from high-income settings and mainly included people who use drugs or those incarcerated. Among manuscripts, 18 had "low" microelimination scores, 11 had "high" scores, and the differences in mean proportion who initiated treatment and achieved SVR between low and high score groups were statistically significant. Microelimination can be a useful complementary strategy for driving engagement in HCV treatment and cure. Our analysis suggests that adhering to more of the core microelimination components can improve outcomes. This study is registered with Prospero, registration identification: CRD42020175211.

Qualitative analysis of the barriers and facilitators influencing uptake of direct-acting antiviral therapy for hepatitis C in a primary healthcare environment

Historical interferon and ribavirin therapies for hepatitis C virus have been replaced by modern treatments with improved efficacy and tolerability. Despite the availability of direct-acting antiviral therapy, evidence demonstrates poor uptake in Australia. Presently, the barriers and facilitators influencing uptake of direct-acting antiviral therapy are not fully understood, especially in a primary healthcare environment. Our study aimed to discover methods of improving uptake of treatment in the community. We conducted 15 semi-structured, face-to-face interviews in a metropolitan, primary healthcare clinic in Australia. Interviews were recorded, transcribed and subsequently analysed using thematic content analysis. We identified patient-related and healthcare system-related barriers and facilitators to commencing treatment. This included established themes from current literature, and novel themes unique to direct-acting antiviral therapy and primary care. Overall, our study reinforces the importance of public health campaigns to promote community awareness and emphasises the concomitant role of mental health in fostering treatment uptake. Informed by our findings, we suggest further research on an integrated model of care, focused on the domains of disease awareness, patient engagement and treatment adherence. Hence, a community-oriented approach, driven by primary healthcare, ultimately underpins a successful public strategy to improve outcomes for patients affected by hepatitis C.

Barriers and facilitators to hepatitis C screening and treatment for people with lived experience of homelessness: A mixed-methods systematic review

BACKGROUND

People experiencing homelessness have an increased risk of hepatitis C virus (HCV) infection, with rates higher than the general population. However, their access to HCV diagnosis is limited and treatment uptake is low.

OBJECTIVES

To identify and describe the barriers and facilitators for HCV screening and treatment for adults with lived experience of homelessness in highly developed countries.

METHODS

Bibliographic databases (Embase, MEDLINE, CINAHL and SocINDEX) and grey literature (Google, EThOS, the Health Foundation, Social Care Online, the World Health Organisation, Shelter, Crisis and Pathway) were searched. Two reviewers independently screened and appraised all studies. The Critical Appraisal Skills Programme tool and the Joanna Briggs Institute checklist were used. The analysis involved a three-stage process: coding, theme generation and theme mapping under Penchansky and Thomas's modified access model.

RESULTS

Twelve papers/reports were included in the review. Several interacting factors influence access of people with lived experience of homelessness to HCV testing and treatment. Some mirror those identified for the general population. The precarious conditions associated with the lived experience of homelessness along with the rigidity of hospital settings and lack of awareness emerged as dominant barriers. Flexibility, outreach, effective communication, tailoring and integration of services were found to be important facilitators. Evidence from Black, Asian and minority ethnic groups is limited.

CONCLUSIONS

People experiencing homelessness face multiple barriers in accessing and completing HCV treatment, relating to both their lived experience and characteristics of health systems. Although some barriers are readily amenable to change, others are more difficult to modify. The facilitators identified could inform future targeted measures to improve HCV diagnosis and treatment for people experiencing homelessness. Research is warranted into successful models to promote screening, diagnosis and treatment.

PATIENT OR PUBLIC CONTRIBUTION

Our team includes a peer advocate, a hepatology nurse and a community volunteer, all with significant experience in promoting and engaging in HCV care and outreach for people experiencing homelessness. They contributed to the protocol, interpretation and reporting of the review findings.

Effect of hepatitis C antiviral therapy on oral lichen planus and hyposalivation in inmates

Background

Oral lichen planus (OLP) and hyposalivation have been reported as extrahepatic manifestations of hepatitis C virus (HCV) infection. Our study evaluated the effect of direct antiviral agents (DAAs) on OLP and hyposalivation in convicts with chronic hepatitis C, examining patients before, during and after the antiviral treatment period with direct acting antiviral agents (DAAs).

Methods

We screened 198 inmates for the presence of the HCV antibody. Patients found to be positive underwent a quantitative HCV-RNA test and HCV genotype typing, as well as an oral cavity examination using a scoring system for OLP (REU score) and the clinical oral dryness score (CODS). Subsequently, all patients underwent DAA therapy and a systematic physical examination of the oral cavity at 1, 3 and 6 months from the beginning of treatment.

Results

Fifty patients (25.25%) had a positive HCV-RNA test. At baseline, OLP was detected in 4 patients (8%), with a mean REU score of 10.13±4, and different degrees of hyposalivation were seen in 17 patients (34%), with a mean CODS score of 4.71±1.72. Six months after the start of DAA therapy, we observed resolution of OLP in 3 patients (75%) and improvement in the remaining subject with a significantly lower mean REU score (2±4). Hyposalivation disappeared in 5 patients, improved in 10, and remained unchanged in 2 patients with a significantly lower mean CODS score (0.06±0.24).

Conclusion

This study demonstrated the effectiveness of DAAs in the treatment of OLP and hyposalivation.

An opt-out approach to hepatitis C virus testing in English prisons: the literature underpinning the policy

BACKGROUND

The World Health Organization's aim to eliminate hepatitis C virus (HCV) infection as a public health threat by 2030 is dependent on testing people. HCV prevalence is higher in prisons, so to increase test uptake an 'opt-out' approach to blood-borne virus testing in English and Welsh prisons was introduced.

AIMS

This literature review examines the evidence behind the introduction of this public health policy.

METHODS

Four healthcare databases were searched for publications between January 2000 and February 2020 on the opt-out approach to blood-borne virus testing in prisons.

FINDINGS

Sixteen studies published between 2009 and 2019 were included. Analysis of their findings showed that an increase in HCV test uptake in prisons occurs when an opt-out approach is used in combination with additional interventions. Contextual differences between UK and US prisons may affect HCV test uptake.

CONCLUSION

An opt-out approach to HCV testing in prisons can increase test uptake as part of a complex of interventions.

Hepatitis C treatment as prevention in the prison setting: Assessments of acceptability of treatment scale up efforts by prison correctional and health personnel

BACKGROUND

Hepatitis C (HCV) infection is prevalent in the prison setting, with sharing of unsterile injecting equipment the most common mode of transmission in high income countries. Mathematical modelling suggests that HCV treatment scale-up could prevent onward transmission, known as treatment as prevention. Direct-acting antivirals have enabled rapid scale up of HCV treatment, underpinning the first clinical trial of treatment as prevention in the prison setting. The Surveillance and Treatment of Prisoners with hepatitis C (SToP-C) study was carried out in four correctional centres in New South Wales, Australia. This paper utilises Sekhon's Theoretical Framework of Acceptability to examine correctional, prison health, and study personnel's assessments of acceptability of HCV treatment as prevention in the prison setting.

METHODS

Correctional (n=24) and health personnel (n=17) including officers, nurses (including seven study nurses), and senior administrators across the four prisons where SToP-C was delivered, participated in interviews. This included two maximum security, one minimum security, and one women's medium/minimum security prison. Data analysis was informed by a seven-component theory of acceptability.

RESULTS

Participants reported broad acceptability of HCV treatment as prevention in the prison setting across five components of acceptability (affective attitude, burden, ethicality, perceived effectiveness, and self-efficacy). Attributes contributing to acceptability included reduced HCV prevalence within the prison, and public health benefits for the community when people are released without HCV (affective attitude). Elements which may negatively impact on acceptability included limited clinic space (burden) and lack of correctional officers' understanding of availability of equivalent healthcare in the community (ethicality). System-wide prison participation was viewed as necessary for treatment as prevention to be successful (perceived effectiveness), while nonjudgmental care was seen as instrumental to HCV treatment scale up efforts (self-efficacy).

CONCLUSION

Correctional and prison-based health personnel view HCV treatment as prevention as an acceptable health intervention. Overall, environmental issues relating to implementation (i.e., clinic space) were viewed as requiring a strategic approach to support prison-wide HCV treatment scale up.

New hepatitis C virus infection, re-infection and associated risk behaviour in male Irish prisoners: a cohort study, 2019

BACKGROUND

Prisoners are recognised as a high-risk population and prisons as high-risk locations for the transmission of hepatitis c virus (HCV) infection. Injecting drug use (IDU) is the main driver of HCV infection in prisoners and harm reduction services are often suboptimal in prison settings. HCV prevalence and incident data in prisoners is incomplete which impacts the public health opportunity that incarceration provides in identifying, treating and preventing HCV infection. The aim of this study is to identify new HCV infection and associated risk factors in an Irish male prison.

METHODS

We conducted a follow up (18-month) cohort study on prisoners who had previously tested negative, self-cleared or had been successfully treated for HCV infection. We conducted the study in a male medium security prison located in Dublin Ireland (Mountjoy Prison) using HCV serology, a review of medical records and a researcher-administered questionnaire.

RESULTS

99 prisoners with a mean age of 33.2 yrs. participated in the study and 82(82.8%) completed a research-administered questionnaire. Over half (51%) had a history of drug use from a young age (14.8 yrs.), 49.9% a history of heroin use and 39% a history of IDU. The prevalence of HIV and hepatitis B virus core antibody was 3% and HCV antibody was 22.2%. No new HCV infections were identified in those who had never been infected (n = 77), had self-cleared (n = 9) or achieved sustained virological response (n = 12). Small numbers of prisoners continued to engage in risk-behaviour including, IDU both in the prison (n = 2) and the community (n = 3), sharing syringes (n = 1) and drug taking paraphernalia (n = 6) and receiving non-sterile tattoos (n = 3).

CONCLUSION

Despite the high numbers of Irish prisoners with a history of IDU and HCV infection, new HCV infection is low or non-existent in this population. Small numbers of prisoners continue to engage in risk behaviour and larger studies are required to further understand HCV transmission in this cohort in an Irish and international context.

"I'm not gonna be able to do anything about it, then what's the point?": A broad group of stakeholders identify barriers and facilitators to HCV testing in a Massachusetts jail

BACKGROUND

Despite national guidelines promoting hepatitis C virus (HCV) testing in prisons, there is substantial heterogeneity on the implementation of HCV testing in jails. We sought to better understand barriers and opportunities for HCV testing by interviewing a broad group of stakeholders involved in HCV testing and treatment policies and procedures in Massachusetts jails.

METHODS

We conducted semi-structured interviews with people incarcerated in Middlesex County Jail (North Billerica, MA), clinicians working in jail and community settings, corrections administrators, and representatives from public health, government, and industry between November 2018-April 2019.

RESULTS

51/120 (42%) of people agreed to be interviewed including 21 incarcerated men (mean age 32 [IQR 25, 39], 60% non-White). Themes that emerged from these interviews included gaps in knowledge about HCV testing and treatment opportunities in jail, the impact of captivity and transience, and interest in improving linkage to HCV care after release. Many stakeholders discussed stigma around HCV infection as a factor in reluctance to provide HCV testing or treatment in the jail setting. Some stakeholders expressed that stigma often led decisionmakers to estimate a lower "worth" of incarcerated individuals living with HCV and therefore to decide against paying for HCV testing.".

CONCLUSION

All stakeholders agreed that HCV in the jail setting is a public health issue that needs to be addressed. Exploring stakeholders' many ideas about how HCV testing and treatment can be approached is the first step in developing feasible and acceptable strategies.

An intervention to increase hepatitis C virus diagnosis and treatment uptake among people in custody in Iran

BACKGROUND

Iran is among countries with high opioid agonist therapy (OAT) coverage in prisons, which provides an infrastructure to increase feasibility of HCV programs. We aimed to evaluate the impact of an intervention to improve HCV screening, diagnosis, and treatment, including alongside the provision of OAT, in an Iranian prison.

METHODS

During July-December 2018, in the Gorgan prison, all incarcerated adults (>18 years) received HCV antibody rapid testing and, if positive, provided a venepuncture sample for HCV RNA testing. Participants with positive RNA received direct-acting antiviral (DAA) therapy [(Sofosbuvir/Daclatasvir) for 24 or 12 weeks, respectively, for those with and without cirrhosis]. Response to treatment was measured by the sustained virological response at 12 weeks post-treatment (SVR12).

RESULTS

Among 2015 incarcerated people with a median age of 35 years (IQR:29-41), the majority were male (97%), had not finished high school (68%), and had a history of drug use (71%), of whom 15% had ever injected drugs. A third of participants were receiving OAT, including 54% of those who had ever injected. HCV antibody prevalence was 6.7%, and RNA was detected in 4.6% of all participants; this prevalence was 32.6% and 24.7% among those with a history of injection, respectively. Treatment uptake was 82% (75/92) and was similar among people on OAT and those with a history of injection (81%). The majority completed treatment in prison and were available for SVR12 assessment (71%, 53/75). Achieved SVR12 was 100% (53/53) based on the available case analysis; those who did not have available SVR12 were released either prior to treatment initiation or completion (n = 39).

CONCLUSION

The availability of OAT infrastructure should be considered as an opportunity for enhancing HCV care in prisons. Where resources are limited, the prison harm reduction network could be used to design targeted HCV programs among people who are at higher risk of infection.

Hepatitis C elimination among people incarcerated in prisons: challenges and recommendations for action within a health systems framework

Hepatitis C virus (HCV) is a global public health problem in correctional settings. The International Network on Health and Hepatitis in Substance Users-Prisons Network is a special interest group committed to advancing scientific knowledge exchange and advocacy for HCV prevention and care in correctional settings. In this Review, we highlight seven priority areas and best practices for improving HCV care in correctional settings: changing political will, ensuring access to HCV diagnosis and testing, promoting optimal models of HCV care and treatment, improving surveillance and monitoring of the HCV care cascade, reducing stigma and tackling the social determinants of health inequalities, implementing HCV prevention and harm reduction programmes, and advancing prison-based research.

The role of social capital in facilitating hepatitis C treatment scale-up within a treatment-as-prevention trial in the male prison setting

BACKGROUND AND AIMS

Hepatitis C (HCV) is a global public health concern, particularly in the prison setting where prevalence is substantially higher than in the general population. Direct-acting antivirals have changed the treatment landscape, allowing for treatment scale-up efforts potentially sufficient to achieve prevention of onward transmission (treatment-as-prevention). The Surveillance and Treatment of Prisoners with hepatitis C (SToP-C) study was the first trial to examine the efficacy of HCV treatment-as-prevention in the prison setting. Social capital is a social resource which has been found to influence health outcomes. This qualitative study sought to understand the role of social capital within an HCV treatment-as-prevention trial in the prison setting.

DESIGN

Semi-structured in-depth interviews were undertaken with participants recruited from the SToP-C study following HCV treatment completion (with cure).

SETTING

Three male correctional centres in New South Wales, Australia (including two maximum-security and one minimum-security).

PARTICIPANTS

Twenty-three men in prison participated in semi-structured interviews.

MEASUREMENTS

Thematic analysis of transcripts was completed using a social capital framework, which enabled exploration of the ways in which bonding, bridging and linking social capital promoted or inhibited HCV treatment uptake within a treatment-as-prevention trial.

FINDINGS

Social capital fostered HCV treatment uptake within an HCV treatment-as-prevention trial in the prison setting. Bonding social capital encouraged treatment uptake and alleviated concerns of side effects, bridging social capital supported prison-wide treatment uptake, and linking social capital fostered trust in study personnel (including nurses and correctional officers), thereby enhancing treatment engagement.

CONCLUSIONS

Social capital, including bonding, bridging and linking, can play an important role in hepatitis C treatment-as-prevention efforts within the male prison setting.

"I want to get better, but…": identifying the perceptions and experiences of people who inject drugs with respect to evolving hepatitis C virus treatments

BACKGROUND

The advent of highly tolerable and efficacious direct-acting antiviral (DAA) medications has transformed the hepatitis C virus (HCV) treatment landscape. Yet, people who inject drugs (PWID) - a population with inequitably high rates of HCV and who face significant socio-structural barriers to healthcare access - continue to have disproportionately low rates of DAA uptake. The objective of this study is to explore how PWID with lived experience of HCV perceive and experience DAA treatment, in a setting with universal coverage of these medications since 2018.

METHODS

Informed by a critical interpretive framework, we thematically analyze data from in-depth, semi-structured interviews conducted between January and June 2018 in Vancouver, Canada, with a purposive sample (n = 56) of PWID at various stages (e.g., pre, peri, post) of DAA treatment.

RESULTS

The analysis yielded three key themes: (i) life with HCV, (ii) experiences with and perceptions of evolving HCV treatments, and (iii) substance use and the uptake of DAA treatments. First, participants described how health and healthcare conditions, such as the deprioritizing of HCV (e.g., due to: being asymptomatic, healthcare provider inaction, gatekeeping) and catalysts to care (e.g., symptom onset, treatment for co-morbidities) shaped DAA treatment motivation and access. Second, participants described how individual and community-level accounts of evolving HCV treatments, including skepticism following negative experiences with Interferon-based treatment and uncertainty regarding treatment eligibility, negatively influenced willingness and opportunities to access DAAs. Concurrently, participants described how peer and community endorsement of DAAs was positively associated with treatment uptake. Third, participants favoured HCV care that was grounded in harm reduction, which included the integration of DAAs with other substance use-related services (e.g., opioid agonist therapy, HIV care), and which was often contrasted against abstinence-focused care wherein substance use is framed as a contraindication to HCV treatment access.

CONCLUSIONS

These findings underscore several equity-oriented healthcare service delivery and clinician adaptations that are required to scale up DAAs among PWID living with HCV, including the provision of harm reduction-focused, non-stigmatizing, integrated, and peer-led care that responds to power differentials.

Hepatitis C-related knowledge, attitudes and perceived risk behaviours among people who inject drugs in Kenya: A qualitative study

Despite disproportionately high rates of Hepatitis C (HCV) among people who inject drugs (PWID) in low- and middle-income countries (LMICs), understanding of HCV-related knowledge, attitudes and perceived risk behaviours among this population remains limited. We aimed to elucidate knowledge, attitudes and experiences that could minimise transmission risk and maximise HCV treatment engagement among PWID in Kenya following the integration of HCV screening and education with needle and syringe programmes in drop-in-centres (DICs). We recruited 40 PWID with chronic HCV attending DICs in Nairobi and Coastal Kenya. Semi-structured interviews revealed a general understanding of HCV and awareness of HCV risk behaviours among participants; however, many felt limited control over their transmission risk due to factors such as 'local doctors', or individuals who perform a high volume of high-risk injections. Financial barriers, distance to clinic, poor health status and HCV-related stigma were all noted as barriers to HCV treatment. In conclusion, basic knowledge of and motivation for HCV treatment among PWID accessing DICs in Kenya was high; however, structural barriers and stigma complicate access to care. Local education programmes can address knowledge gaps, and behavioural and structural interventions can maximise the impact of HCV care in LMICs.

Knowledge, attitudes, and acceptability of direct-acting antiviral hepatitis C treatment among people incarcerated in jail: A qualitative study

Introduction

While U.S. jails are critical sites for engagement in HCV care, short lengths-of-stay often do not permit treatment in jail. Therefore, linkage to HCV care after incarceration is crucial. However, little is known about HCV treatment acceptability among justice-involved individuals in U.S. jails. The goal of this study was to understand knowledge, attitudes, and acceptability of HCV treatment among people living with HCV in the New York City (NYC) jail system.

Methods

We recruited 36 HCV-antibody-positive individuals in the NYC jails using clinical data reports and performed semi-structured interviews to explore participants’ attitudes toward HCV treatment in jail and following return to the community. We continued interviews until reaching thematic saturation and analyzed interviews using an inductive, thematic approach.

Results

Participants were mostly male, Latina/o, with a mean age of 40 years. Nearly all were aware they were HCV antibody-positive. Two thirds of participants had some awareness of the availability of new HCV therapies. Key themes included: 1) variable knowledge of new HCV therapies affecting attitudes toward HCV treatment, 2) the importance of other incarcerated individuals in communicating HCV-related knowledge, 3) vulnerability during incarceration and fear of treatment interruption, 4) concern for relapse to active drug use and HCV reinfection, 5) competing priorities (such as other medical comorbidities, ongoing substance use, and housing), 6) social support and the importance of family.

Conclusions

Patient-centered approaches to increase treatment uptake in jail settings should focus on promoting HCV-related knowledge including leveraging peers for knowledge dissemination. In addition, transitional care programs should ensure people living with HCV in jail have tailored discharge plans focused on competing priorities such as housing instability, social support, and treatment of substance use disorders.

How do people in prison feel about opt-out hepatitis C virus testing?

The prison population is central to the campaign to eliminate hepatitis C virus as a public health threat. In the UK, this has led to the introduction of a national 'opt-out' policy, requiring people in prison to be tested for HCV unless they decline, with a target to test 75% of those admitted. However, in a representative prison estate in the East Midlands of England (20,000 prison entrants per annum) testing rates were only 13.4%. This qualitative study explains why the rates of test uptake are so far short of target. This qualitative study examines the experiences of 45 people in prison about hepatitis C virus testing in an English category C (low security) prison. The data collection method was semi-structured interviews. The data were coded and analysed according to the research questions, and interpretation of the data was aided by the use of a thematic network approach. The themes Fear, Insufficient Knowledge, Stigma, Privacy, Choice and Prison Life emerged as the principal barriers to test uptake. Test Uptake Facilitators that promoted testing were identified by participants and benefits presented of prison health care being a Health Farm. In order to increase hepatitis C virus test uptake, significant changes and flexibility in the timing, location, and staff deployed to test are required. Providing information to people in prison about hepatitis C virus transmission and treatment may reduce fears and enable the test uptake target to be met and sustained.

Ethical guidance for health research in prisons in low- and middle-income countries: a scoping review

OBJECTIVES

This study examined the extent, range and nature of the published literature, prison policies and technical guidance relating to the ethical conduct of health research in prisons in low- and middle-income countries (LMICs).

STUDY DESIGN

Scoping Review.

METHODS

We adhered to the five stages of the scoping review iterative process: identifying the research question, identifying relevant studies, study selection, charting the data, and collating, summarizing and content analysis of polices. Disagreements around allocation of content were resolved through team discussion. We also appraised the quality of the included articles.

RESULTS

We included nine records that examined the ethical aspects of the conduct of health research in prisons in LMICs; eight of these were peer-reviewed publications, and one was a toolkit. Despite the unique vulnerabilities of this group, we could find no comprehensive guidelines on the ethical conduct of health research in prisons in LMICs.

CONCLUSIONS

The majority of the world's imprisoned populations are in LMICs, and they have considerable health needs. Research plays an important role in addressing these needs and in so doing, will contribute to the achievement of the Sustainable Development Goals. With regards to health research, imprisoned people in LMICs are 'left behind'; there is a lack of clear, prison-focused guidance and oversight to ensure high quality ethical health research so necessary in LMICs. There is an urgent need for prison health experts to work with health research ethics experts and custodial practitioners for procedural issues in the development of prison-specific ethical guidance for health research in LMICs aligned with international standards.

Accelerating the elimination of hepatitis C in Kuwait: An expert opinion

The hepatitis C virus (HCV) is estimated to affect 71 million people worldwide. In 2016, the World Health Organization adopted the first global health sector strategy to eliminate viral hepatitis as a public health threat by 2030. In December 2018, the European Association for the Study of the Liver, International Liver Foundation convened an expert panel to address the elimination of HCV in Kuwait. Several steps have already been taken to eliminate HCV in Kuwait, including free HCV treatment for Kuwait’s citizens, high blood safety standards, and the implementation of screening and awareness programs. The expert panel made several recommendations aimed at accelerating the elimination of HCV in Kuwait: The development of a national strategy and action plan to guide all HCV elimination activities; the formation of a coordination mechanism to support collaboration between hepatitis working committees; the prioritization of micro-elimination at primary, secondary or tertiary facilities, in prisons and rehabilitation centers; and ensuring the involvement of multiple stakeholders – including relevant civil society groups – in all activities. Enhanced screening and linkage to care should be prioritized in Kuwait, with the expansion of the prescriber base to primary healthcare providers and nurse practitioners to be considered. Raising awareness and educating people about HCV infection also remain essential to achieve the goal of HCV elimination. Lastly, a national HCV registry should be developed to help monitor the implementation of viral hepatitis plans and progress towards achieving national and international targets.

The role of prison-based interventions for hepatitis C virus (HCV) micro-elimination among people who inject drugs in Montréal, Canada

BACKGROUND

In Canada, hepatitis C virus (HCV) transmission primarily occurs among people who inject drugs (PWID) and people with experience in the prison system bare a disproportionate disease burden. These overlapping groups of individuals have been identified as priority populations for HCV micro-elimination in Canada, which is currently not on track to achieve its elimination targets. Considering the missed opportunities to intervene in provincial prisons, this study aims to estimate the population-level impact of prison-based interventions and post-release risk reduction strategies on HCV transmission among PWID in Montréal, a Canadian city with high HCV burden.

METHODS

A dynamic HCV transmission model among PWID was developed and calibrated to community and prison bio-behavioural surveys in Montréal. Then, the relative impact of prison-based testing and treatment or post-release linkage to care (both 90% testing and 75% treatment coverage), alone or in combination with strategies that reduce the heightened post-release transmission risk by 50%, was estimated from 2018 to 2030, and compared to counterfactual scenarios.

RESULTS

Prison-based test-and-treat strategies could lead to the greatest declines in incidence (48%; 95%CrI: 38-57%) over 2018-2030 and prevent the most new first chronic infections (22%; 95%CrI: 16-28%) among people never exposed to HCV. Prison testing and post-release linkage to care lead to a slightly lower decrease in incidence and prevented fraction of new chronic infections. Combining test-and-treat with risk reduction measures could further its epidemiological impact, preventing 35% (95%CrI: 29-40%) of new first chronic infections. When implemented concomitantly with community-based treatment scale-up, prison-based interventions had synergistic effects, averting a higher fraction of new first chronic infections.

CONCLUSION

Offering HCV testing and treatment in provincial prisons, where incarcerations are frequent and sentences short, could change the course of the HCV epidemic in Montréal. Prison-based interventions with potential integration of post-release risk reduction measures should be considered as an integral part of HCV micro-elimination strategies in this setting.

Individual and network factors associated with HCV treatment uptake among people who inject drugs

BACKGROUND

Hepatitis C virus (HCV) treatment uptake among people who inject drugs (PWID), a population with disproportionately high rates of HCV, remains low. Peers have been shown to positively impact a broad range of health outcomes for PWID. There is, however, limited data on the impact of PWID social network members on HCV treatment.

METHODS

HCV-infected PWID enrolled in an ongoing community-based cohort were recruited as "indexes" to complete an egocentric social network survey. The survey elicited from the index PWID a list of their network members and the index's perception of network member characteristics. Logistic regression analyses were conducted to compare individual and network factors associated with HCV treatment in the index PWID.

RESULTS

Among 540 HCV-infected PWID, the mean age was 55.7 years and the majority were black (87.2%) and male (69.8%). PWID reported a mean of 4.4 (standard deviation [SD] 3.2) network members, most of whom were relatives (mean 2.2 [SD 1.5]). In multivariable analysis, increasing index age and HIV infection were positively associated with HCV treatment, while drug use and homelessness in the preceding 6 months were negatively associated with HCV treatment. From a network perspective, having at least one network member who regularly talked with the index about seeing their doctor for HIV care was associated with HCV treatment (Adjusted Odds Ratio [AOR] 2.7; 95% Confidence Interval (CI) [1.3, 5.6]). Conversely, PWID who had at least one network member who helped them understand their HCV care were less likely to have been HCV treated (AOR 0.2; CI [0.1, 0.6).

CONCLUSION

HCV treatment uptake in this group of PWID appeared to be positively influenced by discussions with network members living with HIV who were in care and negatively influenced by HCV information sharing within PWID networks. These findings underscore the influence of peers on health seeking behaviors of their network members and emphasizes the importance of well-informed peers.

Evaluating peer-supported screening as a hepatitis C case-finding model in prisoners

BACKGROUND

Hepatitis C Virus (HCV) infection is endemic in prison populations, and HCV management in prisons is suboptimal. Incarceration is a public health opportunity to target this cohort. Community peer support increases HCV screening and treatment uptake. Prison peer workers have the potential to support the engagement of prisoners with health services and reduce stigma. This study's primary aim is to evaluate peer-supported screening as a model of active HCV case finding with a secondary aim to describe the HCV cascade among those infected including linkage to care and treatment outcomes.

METHODS

An observational study was conducted in a medium-security Irish male prison housing 538 inmates, using a risk-based questionnaire, medical records, peer-supported screening, laboratory-based HCV serology tests and mobile elastography.

RESULTS

A prison peer-supported screening initiative engaged large numbers of prisoners in HCV screening (n = 419). The mean age of participants was 32.8 years, 92% were Irish and 33% had a history of injecting drug use. Multiple risk factors for HCV acquisition were identified including needle sharing (16%). On serological testing, 87 (21%) were HCV Ab +ve and 50 (12%) were HCV RNA +ve of whom 80% were fibroscaned (25% showing evidence of liver disease). Eighty-six percent of those with active infection were linked with HCV care, with 33% undergoing or completing treatment. There was a high concordance with HCV disclosure at committal and serological testing (96% for HCV Ab +ve and 89% for HCV Ab -ve).

CONCLUSION

Peer-supported screening is an effective active HCV case-finding model to find and link prisoners with untreated active HCV infection to HCV care.

Hepatitis C virus screening and treatment in Irish prisons from nurse managers' perspectives - a qualitative exploration

BACKGROUND

Prisoners carry a greater burden of physical, communicable and psychiatric disease compared to the general population. Prison health care structures are complex and provide challenges and opportunities to engage a marginalised and poorly served group with health care including Hepatitis C Virus (HCV) screening, assessment and treatment. Optimising HCV management in prisons is a public health priority. Nurses are the primary healthcare providers in most prisons globally. Understanding the barriers and facilitators to prisoners engaging in HCV care from the perspectives of nurses is the first step in implementing effective strategies to eliminate HCV from prison settings. The aim of this study was to identify the barriers and facilitators to HCV screening and treatment in Irish prisons from a nurse perspective and inform the implementation of a national prison-based HCV screening program.

METHODS

A qualitative study using focus group methodology underpinned by grounded theory for analysis in a national group of nurse managers (n = 12).

RESULTS

The following themes emerged from the analysis; security and safety requirements impacting patient access, staffing and rostering issues, prison nurses' skill set and concerns around phlebotomy, conflict between maintaining confidentiality and concerns for personal safety, peer workers, prisoners' lack of knowledge, fear of treatment and stigma, inter-prison variations in prisoner health needs and health service delivery and priority, linkage to care, timing of screening and stability of prison life.

CONCLUSIONS

Prison nurses are uniquely placed to identify barriers and facilitators to HCV screening and treatment in prisoners and inform changes to health care practice and policy that will optimise the public health opportunity that incarceration provides.
