Survey of US Correctional Institutions for Routine HCV Testing

Development and optimisation of a reception testing protocol designed to eliminate HCV in the UK prison population

Background & Aims

Micro-elimination of hepatitis C virus (HCV) in high-risk populations is a feasible approach towards achieving the World Health Organization's targets for viral hepatitis elimination by 2030. Prisons represent an area of high HCV prevalence and so initiatives that improve testing and treatment of residents are needed to eliminate HCV from prisons. This initiative aimed to improve the HCV screening and treatment rates of new residents arriving at prisons in England.

Methods

A rapid test and treat pathway was developed and implemented in 47 prisons in England between May 2019 and October 2021 as a healthcare service improvement initiative. Prison healthcare staff performed opt-out HCV testing for all new residents at each prison within 7 days of arrival, and those who were positive for HCV RNA were offered treatment with direct-acting antivirals (DAAs). The Hepatitis C Trust provided peer support for all residents on treatment and those who were released into the community.

Results

Of 107,260 new arrivals, 98,882 (92.2%) were offered HCV antibody testing, 63,137 (63.9%) were tested and 1,848 were treated. Testing rates increased from 53.7% in Year 1 to 86.0% in Year 3. Between May 2020 and October 2021, 40,727 residents were tested, 2,286 residents were positive for HCV antibodies and 940 residents were HCV RNA positive, giving an antibody prevalence of 5.6% and an RNA prevalence of 2.3%. A total of 921 residents were referred for treatment and 915 initiated DAA treatment (97.3% of whom were HCV RNA positive).

Conclusions

This initiative showed that an opt-out HCV test and treat initiative in prison receptions is feasible and can be adapted to the needs of individual prisons as a viable way to achieve HCV micro-elimination.

Impact and implications

Prisons represent an area of high HCV prevalence and so initiatives that improve testing and treatment of residents are needed to eliminate HCV from prisons. The reception testing protocol improved HCV screening in new arrivals across 47 prisons in England and could be a viable way for countries to achieve HCV micro-elimination in their prison systems. The reception testing protocol presented here can be adapted to the individual needs of prisons, globally, to improve HCV screening and treatment in this setting.

Viral Hepatitis C New Microelimination Pathways Objective: Psychiatric Communities HCV Free

BACKGROUND

People with psychiatric disorders have a high prevalence of HCV. For this reason, tailored interventions should be developed to reach this population.

METHODS

We performed a retrospective study on patients treated for HCV infection in psychiatric nursing homes, approached with a quick diagnosis, staging and treatment.

RESULTS

We included data on 586 people screened for HCV with quick tests. High HCV seroprevalence was found in this population (231; 39.4%). Among people who tested positive, there were high rates of active infection (220; 95.2%). Out of the 220 patients with active infection, 95.9% were male, 85.5% were Italian, median age was 43 (IQR = 35-52) years old. In the majority of cases (162; 73.6%), the risk factor was unknown. The most common genotype was 3a (98; 44.5%), and patients mostly had a low fibrosis, according with FIB-4 value (142; 64.5%). Of them, one (0.45%) categorically refused the treatment, and one (0.45%) had liver cirrhosis and advanced hepatocellular carcinoma. Overall, 218 patients underwent eligibility for DAAs. The most prescribed treatment was glecaprevir/pibrentasvir (GLE/PIB (172; 78.2%)). The others practiced sofosbuvir/velpatasvir (SOF/VEL). All patients reached the end of treatment. One (0.45%) was lost to follow up, and all the others reached the SVR12.

CONCLUSIONS

The point-of-care testing and pangenotypic DAAs' availability represent one of the most important steps for a fast diagnostic and therapeutical option. Tailored microelimination pathways for every difficult-to-reach/to-treat populations are needed. This would allow us to move more easily towards HCV elimination.

HCV spread among female incarcerated population and treatment pathways to viral elimination in Italian prison settings: clinical perspectives and medico legal aspects

Background

Hepatitis C virus (HCV) infection is more frequent among incarcerated people than in general population. In the DAAs era, the short schedules and the low risk of adverse reactions, increased the number of HCV treatments. However, the most part of literature reports lack of incarcerated women inclusion in studies on field. Our aim is to assess the screening execution, HCV prevalence, and DAAs treatment among incarcerated women. A focused insight on quick vs standard diagnosis and staging approach will be also provided.

Methods

Incarcerated women from 4 Italian regions’ penitentiary institutes were included. HCV screening was executed with HCV saliva test (QuickOral Test^®) or phlebotomy. Stage of liver fibrosis was evaluated with FIB-4 value or fibroscan^®, based on physicians’ decision. Treatment prescription followed national protocols.

Results

We included 156 women, 89 (57%) were Italian, mean age was 41 ± 10 years, and 28 (17.9%) were people who inject drugs (PWIDs). Overall, the HCV seroprevalence was 20.5%. Being PWID and on opioid substitution therapy (OST) were significantly associated with serological status (p-value < 0.001). Of them, the 75.5% of patients had active infection, the most frequent genotype was 3a (50%). Among them, 4 (16.6%) and 6 (25%) had psychosis or alcohol abuse history. The 62.5%, 25% and 12.5% had low, intermediate, and advanced fibrosis, respectively. Out of the 24 HCV-RNA positive patients, the 75% underwent to DAAs treatment. The sustained virological response (SVR12) was achieved in 88.8% of cases. When evaluating the influence of quick diagnosis and staging methods vs standard phlebotomy and fibroscan^® on SVR12, FIB-4 use showed higher performance for retainment in treatment during prison staying (p = 0.015), while the use of quick saliva test had no influence on the outcome (p = 0.22).

Conclusion

HCV seroprevalence and active infections are very high among incarcerated women. More tailored interventions should be focused on HCV diagnosis and treatment in female prison population. The use of quick staging methods (FIB-4) is useful to increase SVR12 achievement without delays caused by the fibroscan^® awaiting.

Heterogeneity in Jail Nursing Medical Intake Forms: A Content Analysis

Despite high prevalence of infectious diseases and substance use disorders in jails, there are limited guidelines for the nursing intake process in this setting. We performed a content analysis of nursing intake forms used at each of the 14 Massachusetts county jails, focusing on infectious disease and substance use disorder. Only 85% of jails offered HIV testing during nursing intake and 50% of jails offered hepatitis C testing. Preventive interventions such as vaccines or pre-exposure prophylaxis therapy were infrequently offered during nursing intake. Screening for substance use disorder was present on the majority of intake forms, but only 23% of intake forms inquired about ongoing medication-assisted treatment for opioid use disorder. The results reflect heterogeneity in nursing intake forms, highlighting missed opportunities for public health interventions.

Validity of Self-Reported Hepatitis C Virus Status Among Criminal Justice-Involved Persons Living With HIV

The prevalence of HIV/hepatitis C virus (HCV) coinfection among justice-involved persons is high. The validity of self-reported HCV status in this population has important public health implications, yet has not been studied. Justice-involved persons with HIV from Washington, DC, were enrolled in a study that investigated a mobile health intervention to support HIV treatment. Self-reported and laboratory-confirmed HCV status was compared. Among 103 participants, chronic HCV prevalence was 13%. Positive predictive value of self-reported positive chronic HCV status was low at 55%, and negative predictive value was 98%. Cohen's kappa statistic was 0.60 for agreement. Two women who reported negative HCV status were found to have HCV.

Hepatitis C Diagnosis: Simplified Solutions, Predictive Barriers, and Future Promises

The simplification of current hepatitis C diagnostic algorithms and the emergence of digital diagnostic devices will be very crucial to achieving the WHO's set goals of hepatitis C diagnosis (i.e., 90%) by 2030. From the last decade, hepatitis C diagnosis has been revolutionized by the advent and approval of state-of-the-art HCV diagnostic platforms which have been efficiently implemented in high-risk HCV populations in developed nations as well as in some low-to-middle income countries (LMICs) to identify millions of undiagnosed hepatitis C-infected individuals. Point-of-care (POC) rapid diagnostic tests (RDTs; POC-RDTs), RNA reflex testing, hepatitis C self-test assays, and dried blood spot (DBS) sample analysis have been proven their diagnostic worth in real-world clinical experiences both at centralized and decentralized diagnostic settings, in mass hepatitis C screening campaigns, and hard-to-reach aboriginal hepatitis C populations in remote areas. The present review article overviews the significance of current and emerging hepatitis C diagnostic packages to subvert the public health care burden of this 'silent epidemic' worldwide. We also highlight the challenges that remain to be met about the affordability, accessibility, and health system-related barriers to overcome while modulating the hepatitis C care cascade to adopt a 'test and treat' strategy for every hepatitis C-affected individual. We also elaborate some key measures and strategies in terms of policy and progress to be part of hepatitis C care plans to effectively link diagnosis to care cascade for rapid treatment uptake and, consequently, hepatitis C cure.

Structures, processes and outcomes of health care for people detained in short-term police custody settings: A scoping review

BACKGROUND

People detained in short-term custodial settings can require health care that may necessitate transfer to an Emergency Department (ED). What and how health care is delivered to detainees in short-term custodial settings may influence their health outcomes.

OBJECTIVE

The aim of this scoping review was to synthesise and critically appraise the evidence on health care delivered to detainees in short-term custody settings.

DESIGN

A scoping review was undertaken. Five online databases (CINAHL, PubMed, Medline, Embase and Criminal Justice Database) were searched from January 2010 to May 2020. Data extracted pertained to the structures, processes and outcomes of health care delivery. The Mixed Methods Assessment Tool was used to quality appraise the studies. Deductive analysis was used to sort the findings into structures, processes and outcomes of health care delivery and then thematic analysis was undertaken to synthesise these findings.

RESULTS

In total, 37 studies with varied designs were included in this review; 3 randomised control trials, 4 quantitative comparative studies, 21 quantitative descriptive studies, 8 qualitative studies and 1 mixed methods study. Studies were mainly from westernised countries. The quality of evidence varied across studies. Health care delivery structures had a strong focus on the identification of mental illness, with processes predominantly comprising health assessment screening on arrival to the short-term custodial setting. Outcomes (at the detainee and organisation level) included increased identification of substance misuse issues and improvement of health conditions, alongside inadequate assessment/identification of physical and mental health issues for detainees.

CONCLUSION

Gaps in evidence identified limited international perspectives as most studies originated from the US, a focus on detainee conditions/symptoms and limited long-term research within the area of health care in short-term custodial settings. Literature regarding health care delivery in short-term custodial settings focused predominantly on mental illness identification. Understanding the nature of health care delivery in short-term custodial settings further through research into specific roles such as the custody nurse is required to develop targeted interventions that address the needs of the detainee on a comprehensive level.

"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.

Linking criminal justice-involved individuals to HIV, Hepatitis C, and opioid use disorder prevention and treatment services upon release to the community: Progress, gaps, and future directions

Improving HIV and Hepatitis C Virus (HCV) management among people involved in the criminal justice (CJ) system who use drugs, in particular those with opioid use disorder (OUD), requires effective approaches to screening, linkage, and adherence to integrated prevention and treatment services across correctional and community agencies and providers. This manuscript reviews the literature to explore gaps in HIV, Hepatitis C, and OUD prevention, treatment, and delivery cascades of care for persons involved in the CJ system. Specifically, we compare two models of linkage to prevention and treatment services: Peer/Patient Navigation (PN) wherein the PN links CJ-involved individuals to community-based infectious disease (ID) and substance use prevention and treatment services, and Mobile Health Units (MHU) wherein individuals are linked to a MHU within their community that provides integrated ID and substance use prevention and treatment services. The most notable finding is a gap in the literature, with few to no comparisons of models linking individuals recently released from the CJ system to integrated HIV, Hepatitis C, and OUD prevention and treatment and other harm reduction services. Further, few published studies address the geographical distinctions that affect service implementation and their effects on these substance use, ID and harm reduction care cascades. This manuscript makes specific recommendations to fill this gap through a detailed evaluation of PN and MHU linkage models to co-located and integrated HIV, Hepatitis C, and OUD prevention and treatment services across different communities within the U.S.

Hepatitis C Virus and Hispanic Criminal Justice Clients: A Missed Opportunity

To compare the willingness for HCV testing, HCV-knowledge, socio economic status, and HCV related risky behavior among male and female Latino offenders. Participants (n = 201) were recruited from the corrections system in Miami and interviewed. Backward stepwise logistic regression was conducted to compare gender-associated risk. Females (n = 81) were more likely to be engaged in risky sexual and drug behavior compared to males (n = 120). Overall, around 70% of the study population were interested to be tested for HCV if offered with no gender difference (OR 1.4, 95% CI 0.4-4.9). However, females were more likely to have lower income (OR 0.6, 95% CI 0.5-0.9) and engage in more HCV related risky sexual behaviors (OR 2.9, 95% CI 1.3-6.2), despite having better HCV related knowledge in five out of six items (OR 1.5-3.2), but had less crime activity (OR 0.6, 95% CI 0.5-0.8). HCV screening among Latino offenders would offer an efficient opportunity to reduce its burden as well as increase knowledge among vulnerable and high-risk population.

Opioid Use and Chronic Infections: The Value of Addressing the Syndemic in Correctional Settings Via Telemedicine Guidance and Broader Use of Long-Acting Medications

In the United States, we are experiencing linked epidemics (a syndemic) of substance use disorders (SUDs) and infections associated with drug use, including unsafe injecting and unsafe sex in exchange for drugs or money. Current drug laws, together with risk-taking behavior among persons with SUDs, contribute to disproportionately high prevalences of these conditions in correctional settings. Detection and treatment of diseases with a high impact on public health are best addressed in the settings where such conditions are most prevalent (ie, jails and prisons for SUDs and chronic infections). The effectiveness, safety, cost of care. and public health impact of these conditions can be improved by means of broader screening and expanded access to specialty consultations through telemedicine/telehealth, along with broader use of long-acting medications for the treatment of human immunodeficiency virus and SUDs. Expanding telemedicine/telehealth, first for specialties which do not require advanced technology (eg, infectious diseases, addictions), can eventually lead to further advancements in correctional healthcare.

Innovations in Hepatitis C Screening and Treatment

New therapies offer hope for a cure to millions of persons living with hepatitis C virus (HCV) infection. HCV elimination is a global goal that will be difficult to achieve using the traditional paradigms of diagnosis and care. The current standard has evolved toward universal HCV screening and treatment, to achieve elimination goals. There are several steps between HCV diagnosis and cure with major barriers along the way. Innovative models of care can address barriers to better serve hardly reached populations and scale national efforts in the United States and abroad. Herein, we highlight innovative models of HCV care that aid in our progress toward HCV elimination.

Establishing an Epidemiologic Profile of Hepatitis C Virus Infection at the Los Angeles County Jail

OBJECTIVE

The hepatitis C virus (HCV) is the most common blood-borne infection in the United States. Although 2% to 3% of the global population is estimated to be infected with HCV, an estimated 18% of the US prison population may be infected. The objective of this study was to establish an epidemiologic profile of HCV infection in the largest urban jail system in the United States.

METHODS

We retrospectively analyzed 20 years of data on demographic characteristics, risk factors, and HCV positivity among 80 681 individuals incarcerated at the Los Angeles County Jail who were tested for HCV infection from January 1, 2000, through December 31, 2019. We used multivariate logistic regression analysis to determine predictors of HCV positivity.

RESULTS

Of the 80 681 individuals tested, 27 881 (34.6%) had positive test results for HCV infection. In the multivariate analysis, HCV positivity was most strongly associated with injection drug use (adjusted odds ratio [aOR] = 34.9; 95% CI, 24.6-49.5) and being born during 1946-1955 (aOR = 13.0; 95% CI, 11.9-14.2). Men were more likely than women to have HCV infection (aOR = 1.4; 95% CI, 1.3-1.5), and Hispanic (aOR = 4.2; 95% CI, 3.9-4.4) and non-Hispanic White (aOR = 3.8; 95% CI, 3.5-4.0) individuals were more likely than non-Hispanic African American individuals to have HCV infection. Noninjection drug use, homelessness, and mental health issues were also significantly associated with HCV positivity.

CONCLUSION

Even in the absence of resources for universal screening for HCV infection, the creation of a risk profile and its implementation into a screening program may be a beneficial first step toward improving HCV surveillance and establishing an accurate estimate of HCV infection in the incarcerated population.

HCV testing and treatment initiation in an Italian prison setting: A step-by-step model to micro-eliminate hepatitis C

BACKGROUND

HCV infection among vulnerable populations is currently a major issue for HCV elimination program. Incarcerated people and people who inject drugs (PWIDs) are key population groups potentially at high risk for HCV infection. Our aim was to evaluate an extended program of screening, staging and treatment in Italian prison settings.

METHODS

Patients from eight prisons in five different Italian Regions were enrolled. HCV saliva test (QuickOral Test®) was offered. Data on infection awareness and illicit drug use were also collected. Positive patients underwent early HCV RNA evaluation, staging and prescription on DAAs treatment. The definition of PWID was based on self-reported injecting drug use extracted from medical records (injecting drug use during the previous six months).

RESULTS

A total of 2,376 out of 2,687 individuals (88%) was tested. The median (IQR) age was 42 (32-50) years. PWIDs were 537out of 2,376 (23%). Prevalence of HCV antibodies was 10.4% (248/2,376). PWIDs had a lower awareness of their HCV-Ab positivity than non-PWIDs (p-value <0.001). Furthermore, PWIDs were less likely to be previously treated than non-PWIDs (78% vs 96%, p-value= 0.017). Active infection was found in 41% of patients (101/248). Overall, 61% HCV-positive were PWIDs, with 44% HCV RNA positive. HCV therapy was prescribed to 83% (84/101) of patients with active HCV infection and 67% of these (56/84) were PWIDs. Prescription for HCV treatment in PWIDs accounted for 84% (56/67) (while for non-PWIDs was 82% (28/34) p-value: 0.88. Seventeen patients were referred to a Specialist in other prisons because they were going to be transferred soon to another prison. EOT, as well as SVR12 were achieved in 98% (82/84) treated patients.

CONCLUSIONS

Among patients, PWIDs had a lower awareness of their HCV-Ab positivity and had previously received less treatments. Saliva test allowed to achieve a more rapid result, stage, and treatment approach. More than 80% of patients underwent treatment, without differences between PWIDs and non-PWIDs. Linkage to care during prison transfer allowed to avoid unplanned interruptions and offered more chances to reach the end of treatment.

Hepatitis C Virus Infection in the Dallas County Jail: Implications for Screening, Prevention, and Linkage to Care

OBJECTIVES

Screening for hepatitis C virus (HCV) infection in jail provides an opportunity to educate and offer care to a high-risk population. We aimed to (1) estimate the prevalence of HCV infection in jail; (2) describe the demographic characteristics, risk factors, and pre-incarceration health insurance status associated with HCV infection; and (3) examine the implementation of HCV screening in jail.

METHODS

We conducted a retrospective analysis of an opt-out HCV screening program with HCV RNA confirmation and patient education at the Dallas County Jail from April 1 through November 2, 2017. We extracted data on test results, demographic characteristics, and release destination from electronic medical records. A nurse navigator recorded data on patient self-reported risk factors and pre-incarceration health insurance status.

RESULTS

Of 4089 incarcerated persons screened, 708 (17.3%) had a positive HCV antibody result. Of these, 641 (90.5%) had an HCV RNA test ordered; 576 (89.9%) had RNA tests completed, of whom 413 (71.7%) had a positive HCV RNA result. Of these 413, 352 (85.2%) received patient education. Half of HCV RNA-positive incarcerated persons (n = 207, 50.1%) were born outside the birth cohort (1945-1965). Among those with HCV infection, commonly reported risk factors were injection drug use (168 of 352; 47.8%) and tattoos (82 of 352; 23.4%). Most incarcerated persons with HCV infection (284 of 350; 81.1%) did not have health insurance. HCV antibody prevalence was higher among incarcerated persons released to prison (232 of 961; 24.1%) than to outside agencies (38 of 403; 9.4%) or the community (178 of 1026; 17.4%).

CONCLUSIONS

Screening for HCV with RNA confirmation in jail provides an opportunity for disease education, transmission prevention, and navigation to HCV treatment. Future efforts should examine post-incarceration linkage to care.

Management of Hepatitis C in Delaware Prisons: : Approaching Microenvironmental Eradication

The management of chronic hepatitis C virus (HCV) infection has been transformed due to the arrival of HCV-specific Direct-Acting Antivirals (DAAs), which are safer, more effective, and better tolerated than the interferon-based therapies that preceded them. Compared with community healthcare systems, many prison healthcare systems have been slower to adopt the routine use of HCV DAAs despite the fact that HCV infection disproportionately affects individuals in correctional institutions. In 2015, the Delaware Department of Correction (DDOC) launched a treatment program that prioritized treatment for patients who were at greatest risk of disease complications. To date, 327/345 (95%) of eligible current HCV patients have initiated DAA therapy. A total of 196/199 (98.4%) patients who have initiated treatment and who have post-treatment data available have achieved sustained virologic response, defined as undetectable HCV viral load 12 weeks after treatment. Applying a concept of microenvironmental eradication, it can reasonably be concluded that that DDOC is approaching this benchmark with regard to chronic HCV infection and will soon enter a “maintenance phase,” during which it will be feasible to treat new cases of HCV in real time. Correctional systems with significant numbers of untreated hepatitis C patients may want to consider implementing HCV treatment programs that focus on cost-effectiveness and prioritize treatment for patients who are at greatest risk of disease complications.

Hepatitis C Testing and Patient Characteristics in Washington State's Prisons Between 2012 and 2016

INTRODUCTION

There is no widely accepted testing approach for hepatitis C virus infection in correctional settings, and many U.S. prisons do not provide routine testing. The aim of this study was to determine the most effective hepatitis C virus testing strategy in one U.S. state prison and describe the population with reactive testing.

METHODS

A retrospective analysis was performed using individuals entering the Washington State prison system, which routinely offers hepatitis C virus testing, to compare routine opt-out with current recommendations for risk-based and one-time testing for individuals born between 1945 and 1965. Additionally, liver fibrosis stage was characterized using aspartate aminotransferase to platelet ratio index and Fibrosis-4 index. Analyses were conducted in 2017.

RESULTS

Between 2012 and 2016, a total of 24,567 (83%) individuals were tested for the hepatitis C virus antibody and 4,921 (20%) were reactive (test was positive). There were 2,403 (49%) that had hepatitis C virus RNA testing, with 1,727 (72%) showing chronic infection. Reactive antibody was more prevalent in individuals born between 1945 and 1965 compared with other years (44% vs 17%); however, most cases (72%) were outside of this cohort. Up to 35% of positive reactive tests would be missed with testing targeted by birth cohort and risk behavior. Of chronically infected individuals, 23% had at least moderate liver fibrosis.

CONCLUSIONS

Targeted testing in the Washington State prison system missed a substantial proportion of hepatitis C virus cases; of those with reactive testing, a sizeable proportion of people had at least moderate liver disease, placing them at risk for complications. Routine testing at entry should be considered by U.S. state prisons.

Universal opt-out screening for hepatitis C virus (HCV) within correctional facilities is an effective intervention to improve public health

Purpose

Worldwide efforts to identify individuals infected with the hepatitis C virus (HCV) focus almost exclusively on community healthcare systems, thereby failing to reach high-risk populations and those with poor access to primary care. In the USA, community-based HCV testing policies and guidelines overlook correctional facilities, where HCV rates are believed to be as high as 40 percent. This is a missed opportunity: more than ten million Americans move through correctional facilities each year. Herein, the purpose of this paper is to examine HCV testing practices in the US correctional system, California and describe how universal opt-out HCV testing could expand early HCV detection, improve public health in correctional facilities and communities, and prove cost-effective over time.

Design/methodology/approach

A commentary on the value of standardizing screening programs across facilities by mandating all facilities (universal) to implement opt-out testing policies for all prisoners upon entry to the correctional facilities.

Findings

Current variability in facility-level testing programs results in inconsistent testing levels across correctional facilities, and therefore makes estimating the actual number of HCV-infected adults in the USA difficult. The authors argue that universal opt-out testing policies ensure earlier diagnosis of HCV among a population most affected by the disease and is more cost-effective than selective testing policies.

Originality/value

The commentary explores the current limitations of selective testing policies in correctional systems and provides recommendations and implications for public health and correctional organizations.

Toward the elimination of hepatitis C in the United States

The emergence of effective direct-acting antiviral (DAA) agents has reignited discussion over the potential for hepatitis C elimination in the United States. Eliminating hepatitis C will require a critical examination of technical feasibility, economic considerations, and social/political attention. Tremendous advancement has been made with the availability of sensitive diagnostic tests and highly effective DAAs capable of achieving sustained viral response (SVR) in more than 95% of patients. Eliminating hepatitis C also requires escalating existing surveillance networks to monitor for new epidemics. All preventive interventions such as clean syringe and needle exchange programs, safe injection sites, opioid substitution therapies, and mental health services need to be expanded. Although costs of DAAs have raised budget concerns for hepatitis C elimination, studies have shown that eliminating hepatitis C will produce a savings of up to 6.5 billion USD annually along with other intangible benefits such as increased work productivity and quality of life. Economic models and meta-analyses strongly suggest universal hepatitis C screening for all adults rather than just for birth cohort and high-risk populations. Social and political factors are at least as important as technical feasibility and economic considerations. Due to lack of promotion and public awareness, HCV elimination efforts continue to receive inadequate funding. Social stigma continues to impede meaningful policy changes. Eliminating hepatitis C is an attainable public health goal that will require intense collaboration and sustained public support. (Hepatology 2018;67:2449-2459).

Interventions to increase testing, linkage to care and treatment of hepatitis C virus (HCV) infection among people in prisons: A systematic review

BACKGROUND

While the burden of chronic hepatitis C virus (HCV) infection is significantly higher among people in prisons compared to the general population, testing and treatment uptake remain suboptimal. The aim of this systematic review was to synthesize evidence on the effectiveness of interventions to increase HCV testing, linkage to care and treatment uptake among people in prisons.

METHODS

We searched Medline (Ovid 1996-present), Embase (Ovid 1996-present), and the Cochrane Central Register of Controlled Trials for English language articles published between January 2007 and November 2017. Studies evaluating interventions to enhance HCV testing, linkage to care and treatment uptake for people in prison were included. Two independent reviewers evaluated articles selected for full-text review. Disagreements were resolved by consensus.

RESULTS

A total of 475 unique articles were identified, 29 were eligible for full text review, and six studies were included. All but one study was conducted in the pre-direct-acting antiviral (DAA) era; no studies were conducted in low- or middle-income countries. Of the six studies, all but one focused on testing. Only two were randomised controlled trials; the remaining were single arm studies. Interventions to enhance HCV testing in prison settings included combination risk-based and birth-cohort screening strategies, on-site nurse-led opt-in screening clinics with pre-test counselling and education, and systematic dried blood spot testing. All interventions increased HCV testing, but risk of study bias was high in all studies. Interventions to enhance linkage to care included facilitated referral for HCV assessment and scheduling of specialist appointments; however, risk of study bias was critical.

CONCLUSIONS

There is a lack of recent data on interventions to improve the HCV care cascade in people in prisons. With the introduction of short-course, well-tolerated DAAs, rigorous controlled studies evaluating interventions to improve testing, linkage and treatment uptake for people in prison are necessary.

HCV infection and drug use in Italian detainees: results of validation of EQDP (European Questionnaire on Drug Use in Prison)

Purpose: The aim of this paper is to describe the results of a survey conducted in Italy amongst detainees by administering a specific questionnaire (EQDP, European Questionnaire on Drug Use in Prison), in order to investigate drug use in prison, any sharing of used needles and, lastly, the degree of self-awareness regarding health (more specifically, in terms of HIV, HBV and HCV infection). Structure of the article: The article is split into three parts. The first provides an overview of the methodological guidelines for the EQDP, which were issued in March 2017 by the European Monitoring Centre for Drugs and Drug Addiction. The second describes the structure of the EQDP questionnaire (Italian version). The third provides the results of a survey conducted in Italy using this questionnaire and the health-related implications for the prison community, in particular regarding HCV, HIV and HBV. Results: The data were collected by the self-administration of the questionnaire to groups of a sample consisting of 40 male detainees under in normal prisons. In this type of custody, fewer subjects were substance abusers during previous prison terms than amongst subjects in open prisons. The most common forms of dependence (tobacco, alcohol, THC, cocaine, psychostimulants, hallucinogens, opioids, sedatives) detected were significantly different between the two types of imprisonment and they were easier to identify in the open-prison system. The analysis of the state of health with regard to the above viruses demonstrated that, in open-prison conditions, a higher percentage of subjects have been tested for HIV, HBV and HCV, whereas detainees in normal prison conditions were almost all unaware of their infection status and had a poorer awareness of their health in general. Conclusions:Health status (HBV, HCV, HIV) is not declared amongst normal detainees, who are less aware of their health conditions and receive less risk-reduction intervention. Amongst open-prison detainees, however, all substance users are subject to risk reduction interventions, which are efficacious in improving self-awareness in terms of a greater use of blood tests and treatments for infectious diseases.

Performance of Risk-Based and Birth-Cohort Strategies for Identifying Hepatitis C Virus Infection Among People Entering Prison, Wisconsin, 2014

OBJECTIVES

The prevalence of hepatitis C virus (HCV) infection among young adults is rising in Wisconsin. We examined the prevalence of HCV infection among male and female inmates entering two Wisconsin prisons and evaluated existing and alternate risk-based strategies for identifying HCV infection at intake.

METHODS

We added HCV testing to the intake procedures for all 1,239 adults prison entrants at the Wisconsin Department of Corrections (WDOC) from November 3, 2014, to January 31, 2015. We identified risk factors associated with HCV infection during the routine intake examination and calculated the sensitivity and specificity of risk-based testing strategies for identifying HCV infection.

RESULTS

The prevalence of HCV antibody among prison entrants was 12.5% (95% confidence interval [CI] 10.7, 14.4) overall and was almost two times higher at the women's facility (21.3%, 95% CI 15.4, 27.2) than at the men's facility (11.0%, 95% CI 0.0, 12.9) (p<0.001). The sensitivity and specificity of the WDOC risk-based criteria were 88% (95% CI 83, 93) and 80% (95% CI 78, 83), respectively. Adding a new criterion, the 1945-1965 birth cohort, to the risk-based criteria improved the sensitivity to 92% (95% CI 88, 96) and lowered the specificity to 71% (95% CI 68, 74). Compared with entrants without these risk factors, HCV antibody prevalence was significantly higher among prison entrants who had the following risk factors: injection drug use (prevalence ratio [PR] = 9.9, 95% CI 7.4, 13.2), liver disease (PR=9.7, 95% CI 7.8, 12.0), and elevated levels of alanine transaminase (PR=3.6, 95% CI 2.7, 4.9).

CONCLUSION

The WDOC risk criteria for HCV testing identified 88% of HCV infections among prison entrants. Including the 1945-1965 birth cohort as a criterion along with the other WDOC risk criteria increased the sensitivity of targeted testing to 92%. These findings may be informative to jurisdictions where universal HCV testing is not feasible because of resource limitations.

Correlates of Hepatitis C Virus Infection in the Targeted Testing Program of the New York City Jail System

OBJECTIVE

The objective of this study was to understand predictors of hepatitis C virus (HCV) antibody positivity in a large urban jail system in New York City.

METHODS

We examined demographic characteristics, risk behaviors, and HCV antibody prevalence among 10 790 jail inmates aged 16 to 86 who were screened from June 13, 2013, to June 13, 2014, based on birth cohort or conventional high-risk criteria. We used logistic regression analysis to determine predictors of HCV antibody positivity.

RESULTS

Of the 10 790 inmates screened, 2221 (20.6%) were HCV antibody positive. In the multivariate analysis, HCV antibody positivity was associated most strongly with injection drug use (IDU; adjusted odds ratio [aOR] = 35.0; 95% confidence interval [CI], 28.5-43.0). Women were more likely than men to be infected with HCV (aOR = 1.3; 95% CI, 1.1-1.5). Compared with non-Hispanic black people, Hispanic (aOR = 2.1; 95% CI, 1.8-2.4) and non-Hispanic white (aOR = 1.7; 95% CI, 1.5-2.1) people were more likely to be infected with HCV. Non-IDU, recidivism, HIV infection, homelessness, mental illness, and lower education level were all significantly associated with HCV infection. The prevalence rate of HCV infection among a subset of inmates born after 1965 who denied IDU and were not infected with HIV was 5.6% (198 of 3529). Predictors of HCV infection among this group included non-IDU as well as being non-Hispanic white, Hispanic, recidivist, and homeless.

CONCLUSION

These data reveal differences in HCV infection by sex, race/ethnicity, and socioeconomics in a large jail population, suggesting that a focused public health intervention is required and that universal screening may be warranted. Further sensitivity and cost-benefit analyses are needed to make this determination.

A pilot study of rapid hepatitis C virus testing in the Rhode Island Department of Corrections

BACKGROUND

The correctional population bears a heavy burden of hepatitis C virus (HCV) infection necessitating expansion of HCV testing and treatment opportunities. Rapid HCV testing provides point-of-care antibody results and may be ideal for correctional facilities, particularly jails, where persons are often incarcerated for short periods of time, yet feasibility has not been established.

METHODS

We conducted a pilot study of a rapid HCV testing algorithm among short-term inmates with unknown HCV status. Participants completed a questionnaire, viewed an informational video and underwent rapid HCV testing and confirmatory testing, when indicated. Persons with chronic infection were referred to community care after release. Baseline characteristics, risk behaviors, test results and linkage were examined by descriptive analyses.

RESULTS

Two hundred and fifty-two inmates were enrolled and 249 completed all study activities. Twenty-five participants (10%) had reactive rapid tests and 23 (92%) completed confirmatory testing. 15/23 (65%) had detectable HCV RNA, but only 4 linked to care after release. Persons with reactive HCV tests were more likely to be White (P = 0.01) and to have ever injected (P < 0.0001) and/or recently injected (P < 0.0001) drugs.

CONCLUSIONS

Rapid HCV testing within jails is feasible, identifies previously unrecognized cases of HCV infection, and implementation should be considered. Low rates of linkage to care after release remain a barrier to care.

Evidence-based interventions to enhance assessment, treatment, and adherence in the chronic Hepatitis C care continuum

BACKGROUND

With the explosion of newly available direct acting antiviral (DAA) Hepatitis C virus (HCV) treatments that demonstrate 95% sustained virologic response (SVR) rates, evidence-based strategies are urgently needed to achieve real-world effectiveness in challenging patient populations. While HIV is incurable, lessons from over 30 years of experience overcoming obstacles to the HIV treatment cascade could be applied to the HCV context.

METHODS

Using Institute of Medicine guidelines, we conducted a systematic review of published interventions from PubMed, Medline, GoogleScholar, EmBASE, and PsychInfo bibliographic databases and citation indices. Abstracts were first screened by three independent reviewers and studies were included if they involved original research, described a specific intervention, were published in English in a peer-reviewed journal between 2001 and 2014, and had full text available.

RESULTS

Evidence-based interventions to enhance HCV assessment, treatment, and adherence generally fell into one of 4 categories, including those involving: (1) diagnosis or case-finding; (2) linkage to HCV care; (3) pre-therapeutic evaluation or treatment initiation; or (4) treatment adherence. While most available eligible studies described interventions using non-contemporary interferon-based HCV treatments, future research will need to address how these interventions apply to the context of well-tolerated, simple, oral treatment regimens. In some cases, we explored how HIV-specific interventions might be modified to fit the HCV spectrum of care engagement.

CONCLUSIONS

Evidence-based interventions should be strategically incorporated into HCV treatment implementation efforts to most effectively deliver treatment and maximize treatment outcomes.
