Abstract
INTRODUCTION Introduction of direct acting antivirals (DAA) has transformed treatment of chronic hepatitis C (HCV) and made the elimination of HCV an achievable goal set forward by World Health Organization by 2030. Multiple barriers need to be overcome for successful eradication of HCV. Availability of pan-genotypic HCV regimens has decreased the need for genotype testing but maintained high efficacy associated with DAAs. AREAS COVERED In this review, we will assess the cost-effectiveness of DAA treatment in patients with chronic HCV disease, with emphasis on general, cirrhosis, and vulnerable populations. EXPERT OPINION Multiple barriers exist limiting eradication of HCV, including cost to treatment, access, simplified testing, and implementing policy to foster treatment for all groups of HCV patients. Clinically, DAAs have drastically changed the landscape of HCV, but focused targeting of vulnerable groups is needed. Public policy will continue to play a strong role in eliminating HCV. While we will focus on the cost-effectiveness of DAA, several other factors regarding HCV require on going attention, such as increasing public awareness and decreasing social stigma associated with HCV, offering universal screening followed by linkage to treatment and improving preventive interventions to decrease spread of HCV.

Abstract
Incarcerated persons are infected with hepatitis C virus (HCV) at rates ≈10 times higher than that of the general population in the United States. To achieve national hepatitis C elimination goals, the diagnosis and treatment of hepatitis C in incarcerated persons must be prioritized. In 2022, the Centers for Disease Control and Prevention recommended that all persons receive opt-out HCV screening upon entry into a carceral setting. We review recommendations, treatments, and policy strategies used to promote HCV opt-out universal HCV screening and treatment in incarcerated populations in the United States. Treatment of hepatitis C in carceral settings has increased but varies by jurisdiction and is not sufficient to achieve HCV elimination. Strengthening universal HCV screening and treatment of HCV-infected incarcerated persons is necessary for HCV elimination nationwide.

Abstract
HIV and hepatitis C virus (HCV) testing for all people in jail is recommended by the CDC. In the community, there are barriers to HIV and HCV testing for minoritized people. We examined the relationship between race and infectious diseases (HIV, HCV, syphilis) testing in one Massachusetts jail, Middlesex House of Corrections (MHOC). This is a retrospective analysis of people incarcerated at MHOC who opted-in to infectious diseases testing between 2016-2020. Variables of interest were race/ethnicity, self-identified history of psychiatric illness, and ever having experienced restrictive housing. Twenty-three percent (1,688/8,467) of people who were incarcerated requested testing at intake. Of those, only 38% received testing. Black non-Hispanic (25%) and Hispanic people (30%) were more likely to request testing than white people (19%). Hispanic people (16%, AOR 1.69(1.24-2.29) were more likely to receive a test result compared to their white non-Hispanic (8%, AOR 1.54(1.10-2.15)) counterparts. Black non-Hispanic and Hispanic people were more likely to opt-in to and complete infectious disease testing than white people. These findings could be related to racial disparities in access to care in the community. Additionally, just over one-third of people who requested testing received it, underscoring that there is room for improvement in ensuring testing is completed. We hope our collaborative efforts with jail professionals can encourage other cross-disciplinary investigations.

Abstract
Hepatitis C virus (HCV) infection is a major public health challenge with a simple, highly efficacious, all-oral therapy (direct-acting antivirals) that can achieve cure. Owing to the ease of treatment, the World Health Organization outlined goals to eliminate HCV by the year 2030. However, unforeseen challenges have hampered progress, and few countries are on track to meet these goals. Significant disparities remain among priority populations because of barriers to care on the systemic, provider, and patient levels. In turn, many local, state, and national organizations have been persistent in tackling these barriers, the greatest of which is linkage to care. In 2023, the White House launched a multipronged national initiative to eliminate HCV infection. The resulting economic impact of the national HCV elimination program is estimated to yield a significant net cost savings of $18.1 billion within a 10-year period. This article addresses the barriers to HCV care in different priority populations and discusses innovative models of HCV care that have been introduced in the United States.

Abstract
In the context of historic reckoning with the role of the criminal-legal system as a structural driver of health harms, there is mounting evidence that punitive drug policies have failed to prevent problematic drug use while fueling societal harms. In this explainer article, we discuss how simulation modeling provides a methodological framework to explore the potential outcomes (beneficial and harmful) of various drug policy alternatives, from incremental to radical. We discuss potential simulation modeling opportunities while calling for a more active role of simulation modeling in visioning and operationalizing transformative change. Highlights This article discusses opportunities for simulation modeling in projecting health and economic impacts (beneficial and harmful) of drug-related criminal justice reforms.We call on modelers to explore radical interventions to reduce drug-related harm and model grand alternative futures in addition to more probable scenarios, with a goal of opening up policy discourse to these options.

HCV treatment initiation in the era of universal direct acting antiviral coverage - Improvements in access and persistent barriers. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 113:103954. [PMID: 36758334 DOI: 10.1016/j.drugpo.2023.103954] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 01/04/2023] [Accepted: 01/05/2023] [Indexed: 02/10/2023]
Abstract
BACKGROUND Barriers to HCV treatment initiation persisted after the introduction of direct-acting antivirals (DAAs) in Canada among people who inject drugs (PWID); whether DAA universal coverage lifted these barriers remain unknown. We assessed the evolution of HCV treatment initiation and associated factors among PWID in Montreal, Canada, comparing eras of IFN-based regimens (2011-2013), of DAA restricted access (2014-02/2018), and universal coverage (03/2018-03/2020). METHODS We included chronically HCV-infected participants followed in a community-based PWID cohort in Montreal, Canada between 2011 and 03/2020 and collected data at 3-month intervals. Time-updated Cox regressions were conducted to examine 9 variables of interest associated with treatment initiation overall and for each of the three eras. RESULTS Of 276 participants, 126 initiated treatment during follow-up. Yearly initiation increased from 3% in 2011 to 19% in 2016, and 54% in 2018. PWID aged >40 (vs. ≤40) were twice as likely to initiate treatment in 2014-02/2018 (HR: 2.02 95%CI: [1.24-3.28]) but not in other periods (2011-2013: 0.55 [0.25-1.22]; 03/2018-03/2020: 1.14 [0.59-2.22])). Odds of initiation were lower for men than women in all periods, with women three times more likely to be treated under universal coverage (0.30 [0.11-0.77] vs 2011-2013: 0.67 [0.25-1.78] and 2014-02/2018: 0.75 [0.42-1.35]). Recent incarceration was negatively associated with initiation throughout all periods (2011-2013: 0.57 [0.13-2.43]; 2014-03/2018: 0.39 [0.17-0.91]; 03/2018-03/2020: 0.25 [0.07-0.83]). Barriers associated with high injection frequency appear to have diminished since DAA introduction (2014-02/2018: 0.71 [0.42-1.20]; 03/2018-03/2020: 1.05 [0.52-2.11] vs. 2011-2013: 0.26 [0.08-0.88]). Contact with a primary care physician and engagement in opioid agonist therapy were positively associated with treatment initiation, though estimates were attenuated under universal coverage relative to previous eras. CONCLUSION Treatment initiation rates have increased since the introduction of universal DAA coverage, though barriers such as incarceration persist.

Abstract
BACKGROUND National guidelines recommend twice-yearly hepatitis C virus (HCV) screening for patients receiving in-center hemodialysis. However, studies examining the cost-effectiveness of HCV screening methods or frequencies are lacking. METHODS We populated an HCV screening, treatment, and disease microsimulation model with a cohort representative of the US in-center hemodialysis population. Clinical outcomes, costs, and cost-effectiveness of the Kidney Disease Improving Global Outcomes (KDIGO) 2018 guidelines-endorsed HCV screening frequency (every 6 months) were compared with less frequent periodic screening (yearly, every 2 years), screening only at hemodialysis initiation, and no screening. We estimated expected quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs) between each screening strategy and the next less expensive alternative strategy, from a health care sector perspective, in 2019 US dollars. For each strategy, we modeled an HCV outbreak occurring in 1% of centers. In sensitivity analyses, we varied mortality, linkage to HCV cure, screening method (ribonucleic acid versus antibody testing), test sensitivity, HCV infection rates, and outbreak frequencies. RESULTS Screening only at hemodialysis initiation yielded HCV cure rates of 79%, with an ICER of $82,739 per QALY saved compared with no testing. Compared with screening at hemodialysis entry only, screening every 2 years increased cure rates to 88% and decreased liver-related deaths by 52%, with an ICER of $140,193. Screening every 6 months had an ICER of $934,757; in sensitivity analyses using a willingness-to-pay threshold of $150,000 per QALY gained, screening every 6 months was never cost-effective. CONCLUSIONS The KDIGO-recommended HCV screening interval (every 6 months) does not seem to be a cost-effective use of health care resources, suggesting that re-evaluation of less-frequent screening strategies should be considered.

Abstract
Case detection remains a major challenge for hepatitis C virus (HCV) elimination. We have previously published results from a pilot of an emergency department (ED) semiautomated screening program, SEARCH; Screening Emergency Admissions at Risk of Chronic HCV. Several refinements to SEARCH have been developed to streamline and reduce cost. All direct costs of HCV testing until direct-acting antiviral (DAA) therapy initiation were calculated. Cost was assessed in 2018 Australian Dollars. A cost analysis of the initial program and refinements are presented. Sensitivity analysis to understand impact of variation in staff time, laboratory test cost, changes in HCV antibody (Ab) prevalence, RNA positivity percentage, and rate of linkage to care was conducted. Impact of refinements (SEARCH (2)) to cost is presented. The total SEARCH pilot, testing 5000 patients was estimated to cost $110,549.52 (range $92,109.79-$129,581.24) comprising of $68,278.67 for HCV Ab testing, $21,568.99 for follow-up and linkage to care of positive patients and $20,701.86 to prepare HCV RNA positive patients for treatment. Internal program refinements resulted in a 25% cost reduction. Following refinements, the cost of HCV antibody screening was $8.46 per test and the total cost per positive HCV Ab, positive HCV RNA, and per treated patient were $611.77, $2,168.64, and $3,566.11, respectively. Our sensitivity analysis indicates costs per HCV case found are modest so long as HCV Ab prevalence was at least 1%. ED screening is an affordable strategy for HCV case detection and elimination.

Abstract
PURPOSE Metamodels are simplified approximations of more complex models that can be used as surrogates for the original models. Challenges in using metamodels for policy analysis arise when there are multiple correlated outputs of interest. We develop a framework for metamodeling with policy simulations to accommodate multivariate outcomes. METHODS We combine 2 algorithm adaptation methods-multitarget stacking and regression chain with maximum correlation-with different base learners including linear regression (LR), elastic net (EE) with second-order terms, Gaussian process regression (GPR), random forests (RFs), and neural networks. We optimize integrated models using variable selection and hyperparameter tuning. We compare the accuracy, efficiency, and interpretability of different approaches. As an example application, we develop metamodels to emulate a microsimulation model of testing and treatment strategies for hepatitis C in correctional settings. RESULTS Output variables from the simulation model were correlated (average ρ = 0.58). Without multioutput algorithm adaptation methods, in-sample fit (measured by R2) ranged from 0.881 for LR to 0.987 for GPR. The multioutput algorithm adaptation method increased R2 by an average 0.002 across base learners. Variable selection and hyperparameter tuning increased R2 by 0.009. Simpler models such as LR, EE, and RF required minimal training and prediction time. LR and EE had advantages in model interpretability, and we considered methods for improving the interpretability of other models. CONCLUSIONS In our example application, the choice of base learner had the largest impact on R2; multioutput algorithm adaptation and variable selection and hyperparameter tuning had a modest impact. Although advantages and disadvantages of specific learning algorithms may vary across different modeling applications, our framework for metamodeling in policy analyses with multivariate outcomes has broad applicability to decision analysis in health and medicine.

Cost-effectiveness of mass screening for Hepatitis C virus among all inmates in an Irish prison. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103394.

Abstract
BACKGROUND In Irish prisons, there is a high proportion of people who inject drugs (PWID; 26%) and a high prevalence of HCV (16%), making prison a high priority setting for HCV testing and treatment. We evaluate the cost-effectiveness of a mass HCV screening intervention in Mountjoy Prison, Dublin, compared to the standard-of-care of intermittent screening on committal. METHODS Primary cost data was collected from the intervention using an overall provider perspective. Standard-of-care (SOC) costs were estimated through interview. All costs were inflated to 2020 Euros. An HCV transmission and disease progression model among incarcerated and community PWID and ex-injectors was calibrated to the Dublin HCV epidemic, allowing inclusion of population-level health benefits. The model used intervention data, suggesting 419 individuals were screened, 50 HCV infections diagnosed and 32 individuals initiated treatment, to project the resulting costs and health benefits (quality adjusted life years or QALYs) over 50 years with 5% discounting. The incremental cost effectiveness ratio (ICER), cost per QALY gained, was estimated for the screening intervention compared to the standard-of-care. Probabilistic sensitivity analyses (PSA) determined the probability that the intervention was cost-effective compared to a willingness-to-pay threshold of €30,000/QALY as used in Ireland. The ICER for 1- or 3-yearly mass screening in all Dublin prisons was also calculated. RESULTS The total direct costs of the intervention (not including treatment drug costs) was €82,392, with most costs being due to staff (43%) and overhead or management costs (38%). Despite having little epidemiological impact due to the small numbers treated, over 50 years the incremental cost of the intervention was €36,592 and 3.8 QALYs were gained, giving a mean ICER of €9,552/QALY. The majority (84%) of PSA runs were below the willingness-to-pay threshold. Yearly mass screening had an ICER of €2,729/QALY compared to SOC and gave a higher net monetary benefit (€7,393,382) than screening every 3 years (€6,252,816). CONCLUSION Prison mass screening could be a cost-effective initiative for increasing testing and treatment of HCV in Ireland.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 96:103345. [PMID: 34176704 DOI: 10.1016/j.drugpo.2021.103345] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 05/28/2021] [Accepted: 06/07/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND Implementing opt-out hepatitis C virus (HCV) screening across Canadian provincial prisons is crucial to achieving micro-elimination. Given short incarceration lengths, the most cost-effective screening strategy remains unknown. We compared the cost-effectiveness of current standard of care (venipuncture-based HCV-antibody+HCV RNA) and 13 alternative strategies in Quebec's largest provincial prison. METHODS A prison cohort was simulated with a Markov micro-simulation model. Strategies differed in the biomarkers, sampling methods, and number of tests used. The model considered incarceration lengths, time to linkage to care (LTC), nursing costs, and tests' costs, performances, acceptability and turnaround times. Outcomes included costs (Canadian dollars, CAD$), number of true positives linked to care, and incremental cost-effectiveness ratios (ICERs, additional $/additional TP-L). A one-year time horizon and health-payer perspective were adopted. RESULTS Across all analyses, three strategies consistently provided the best value for money: venipuncture-based HCV-antibody+HCV-core antigen, venipuncture-based HCV-core antigen (base-case ICER=~ $720), and point-of-care HCV-antibody+HCV RNA (base-case ICER=$4,310). However, these strategies linked only 23%-29% viremic individuals to care. Main drivers of cost-effectiveness were the seroprevalence, proportion viremic, and time to LTC. CONCLUSION Alternative strategies would be more cost-effective than standard of care for implementing opt-out screening in provincial prisons. However, interventions to maximize LTC should be explored.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND A simplified cascade-of-care may improve screening and treatment uptake among incarcerated individuals. We assessed the cost-effectiveness of traditional and simplified screening and treatment in a London remand prison. METHODS Using empirical data from Her Majesty's Prison (HMP) Wormwood Scrubs, London, we designed a decision tree and Markov transition state model using national average data for HCV screening and treatment for the base-case scenario. This compared two alternative strategies; (a) general prison population screening and treatment and (b) prioritising screening and treatment among people who inject drugs (PWID) combined with general prison population screening and treatment. Strategies varied the rates of screening (47%-90%), linkage-to-care (60%-86%) and treatment (21%-85%). Cost, utility and disease transition rates were obtained from existing literature. Outcome measures were as follows: screening, treatment and disease-related costs per admitted individual, quality-adjusted life years (QALYs). Incremental cost-effectiveness ratios (ICERs) were calculated for each intervention. All costs and utilities were discounted at a rate of 3.5% per annum. Both univariate and probabilistic sensitivity analyses have been conducted. RESULTS In our cohort of 5239 incarcerated individuals with an estimated chronic HCV prevalence of 2.6%, all strategy ICER values (£3565-10 300) fell below the national willingness to pay threshold (£30 000). Increased successful treatment (7%-54%) was observed by an optimising cascade-of-care. A robust sensitivity analysis identified treatment cost of, QALY for mild liver disease and probability of completing treatment as important factors that impact the ICER value. CONCLUSION In our remand setting, optimising adherence to the cascade-of-care is cost-effective. Where universal screening is not practical, a stratified approach focused on intensive screening and treatment of PWID also results in increased treatment uptake and is highly cost-effective.

Abstract
In March and April of 2020, public health authorities issued major updates to screening recommendations for hepatitis C virus infection. With the rise in cases driven by injection drug use coupled with access to highly effective therapies promising a cure, all adults aged ≥18 years should receive one-time hepatitis C virus antibody screening in any health care setting. Although the recommendation is dubbed "universal," this commentary reviews the details of the recommendations and discusses the high-risk populations not entirely captured with these changes.

Abstract
Dissemination and implementation science seeks generalizable knowledge about closing the gap between clinical discovery and actual use in routine practice and public health. The field of infectious diseases enjoys an abundance of highly efficacious interventions (eg, antimicrobial agents, human immunodeficiency virus treatment) which are not adequately used in routine care, thereby missing critical opportunities to improve population health. In this article, we summarize salient features of dissemination and implementation science, reviewing definitions and methodologies for infectious diseases clinicians and researchers. We give examples of the limited use of dissemination and implementation science in infectious diseases thus far, suggest opportunities for application, and provide resources for interested readers to use and apply to their own research and practice.

Abstract
PURPOSE OF REVIEW The prevalence of Hepatitis C virus (HCV) in the US incarcerated population is disproportionately high, and when inmates with infection are released back into the general population, they play a substantial role in the spread of disease. This review provides support for targeting the jail/prison population to eliminate HCV in the general population. It will also summarize various screening/treatment models to curtail the burden of disease behind and beyond bars. RECENT FINDINGS Transitioning from risk-based testing to opt-out testing in prisons/jails would be cost-effective through greater identification of cases and treatment to prevent complications from cirrhosis. Other innovative strategies, such as the nominal pricing mechanism or the "Netflix" DAA subscription model, have the potential to be cost-effective and to increase access to treatment. Addressing HCV in the incarcerated population is a strategy to bring the US closer to successfully eradicating the epidemic. Such findings should incentivize policymakers to implement care models that target this population.

Abstract
BACKGROUND People who inject drugs (PWID) experience high incarceration rates, with current/recent incarceration being associated with increased hepatitis C virus (HCV) transmission. We assess the contribution of incarceration to HCV transmission amongst PWID in Perry County (PC), Kentucky, USA, and the impact of scaling-up community and in-prison opioid substitution therapy (OST), including the potential for reducing incarceration. METHODS A dynamic model of incarceration and HCV transmission amongst PWID was calibrated in a Bayesian framework to epidemiological and incarceration data from PC, incorporating an empirically estimated 2.8-fold (95%CI: 1.36-5.77) elevated HCV acquisition risk amongst currently incarcerated or recently released (<6 months) PWID compared to other PWID. We projected the percentage of new HCV infections that would be prevented among PWID over 2020-2030 if incarceration no longer elevated HCV transmission risk, if needle and syringe programmes (NSP) and OST are scaled-up, and/or if drug use was decriminalized (incarceration/reincarceration rates are halved) with 50% of PWID that would have been imprisoned being diverted onto OST. We assume OST reduces reincarceration by 10-42%. RESULTS Over 2020-2030, removing the effect of incarceration on HCV transmission could prevent 42.7% (95% credibility interval: 15.0-67.4%) of new HCV infections amongst PWID. Conversely, scaling-up community OST and NSP to 50% coverage could prevent 28.5% (20.0-37.4%) of new infections, with this increasing to 32.7% (24.5-41.2%) if PWID are retained on OST upon incarceration, 36.4% (27.7-44.9%) if PWID initiate OST in prison, and 45.3% (35.9-54.1%) if PWID are retained on OST upon release. decriminalization (with diversion to OST) could further increase this impact, preventing 56.8% (45.3-64.5%) of new infections. The impact of these OST interventions decreases by 2.1-28.6% if OST does not reduce incarceration. CONCLUSION Incarceration is likely to be an important contributor to HCV transmission amongst PWID in PC. Prison-based OST could be an important intervention for reducing this risk.
