“…The high prevalence of HCV infection among PWID in the United States warrants a concerted population approach to HCV treatment to reduce prevalence and ongoing transmission. 21 The young adult PWID participants residing in rural northern New Mexico, where HCV infection is widespread, 19 had a steeply declining level of engagement in cascade of care milestones after HCV infection detection, resulting in a suboptimal level of HCV treatment and cure. Young adult PWID are more likely than older PWID to acquire HCV infection, potentially because of reduced knowledge of HCV status and differences in seroadaptive behaviors that vary by age, which can increase high-risk injection exposures, 22 making young adult PWID a critical population to reach for treatment and elimination efforts.…”

Objective: Treatment for hepatitis C virus (HCV) infection is highly effective; however, people who inject drugs (PWID), the population most affected by HCV, may encounter barriers to treatment. We examined the cascade of care for HCV infection among young adult PWID in northern New Mexico, to help identify gaps and opportunities for HCV treatment intervention. Methods: Young adults (aged 18-29 y) who self-reported injection drug use in the past 90 days were tested for HCV antibodies (anti-HCV) and HCV RNA. We asked participants with detectable RNA to participate in an HCV education session, prior to a referral to a local health care provider for treatment follow-up, and to return for follow-up HCV testing quarterly for 1 year. We measured the cascade of care milestones ranging from the start of screening to achievement of sustained virologic response (SVR). Results: Among 238 participants, the median age was 26 years and 133 (55.9%) were men. Most (90.3%) identified as Hispanic. Of 109 RNA-positive participants included in the cascade of care assessment, 84 (77.1%) received their results, 82 (75.2%) participated in the HCV education session, 61 (56.0%) were linked to care through a medical appointment, 27 (24.8%) attended the HCV treatment appointment, 13 (11.9%) attended their follow-up appointment, 6 (5.5%) initiated treatment, 3 (2.8%) completed treatment, and 1 (0.9%) achieved SVR. Conclusions: We observed a steeply declining level of engagement at each milestone step of the cascade of care after detection of HCV infection, resulting in a suboptimal level of HCV treatment and cure. Programs that can streamline testing and expand access to treatment from trusted health care providers are needed to improve the engagement of PWID in HCV treatment.

“…Unfortunately, many barriers to treatment remain with access to DAA being particularly challenging for vulnerable populations 8 . HCV‐related policy changes have been made in silos around the country with an effort to increase access to health care and DAAs 23 . However, it was unclear whether these policy changes translated into increased treatment rates.…”

Despite the release of a growing number of direct-acting antivirals and evolving policy landscape, many of those diagnosed with hepatitis C virus (HCV) have not received treatment. Those from vulnerable populations are at particular risk of being unable to access treatment, threatening World Health Organization (WHO) HCV elimination goals. The aim of this study was to understand the association between direct-acting antivirals approvals, HCV-related policy changes and access to HCV virus treatment in Indiana, and to explore access to treatment by race, birth cohort and insurance type. We performed a retrospective cohort study of adults with HCV from 05/2011-03/2021, using statewide electronic health data. Nine policy and treatment changes were defined a priori. A Lowess curve evaluated treatment trends over time. Monthly screening and treatment rates were examined. Multivariable logistic regression explored predictors of treatment. The population (N = 10,336) was 13.4% Black, 51.8% was born after 1965 and 44.7% was Medicaid recipients. Inflections in the Lowess curve defined four periods: (1) Interferon + DAA, (2) early direct-acting antivirals, (3) Medicaid expansion/ optimization and (4) Medicaid restrictions (fibrosis/prescriber) removed. The largest increase in monthly treatment rates was during period 4, when Medicaid prescriber and fibrosis restrictions were removed (2.4 persons per month [PPM] in period 1 to 72.3 PPM in period 4, p < 0.001; 78.0% change in slope). Multivariable logistic regression analysis showed being born after 1965 (vs. before 1945; OR 0.69; 95% 0.49-0.98) and having Medicaid (vs. private insurance; OR 0.47; 95% CI 0.42-0.53), but not race was associated with lower odds of being treated. In conclusion, DAAs had limited impact on HCV treatment rates until Medicaid restrictions were removed. Additional policies may be needed to address HCV treatment-related age and insurance disparities.

“…This is due to noncompliance with treatment in the interferon era of therapy as well as the lowest rates of linkage to care and of access to treatment with DAAs. The integration of hepatitis C education, screening, and treatment in harm reduction centers, such as drug and alcohol services, sexual health services, mental health care, and HIV care, has reduced barriers to the uptake of treatment and adherence in this population (7,(11)(12)(13).…”

INTRODUCTION:Given the hepatitis C virus (HCV) burden and despite curative treatments, more efforts focused on scaling-up testing and treatment in homeless populations are needed. This project aimed to implement education and flexible on-site HCV testing, treatment, and follow-up for a homeless population in south London and to evaluate engagement, therapy initiation, and cure rates.METHODS:A mobile unit (van) for on-site HCV education, screening, treatment, and follow-up was placed on the street in a well-known homeless population areas from January 2018 to September 2021. Homeless was defined as living in temporary housing (hostel/hotel-based) or living on the street (street-based). Sociodemographic status, risk factors, comorbidities, concomitant medication, and data related with HCV treatment were recorded. Univariable and multivariable modeling were performed for treatment initiation and sustained virological response (SVR).RESULTS:Nine hundred forty homeless people were identified and 99.3% participated. 56.2% were street-based, 243 (26%) tested positive for HCV antibody, and 162 (17.4%) were viremic. Those with detectable HCV RNA had significantly more frequent psychiatric disorders, active substance use disorders, were on opioid agonist treatment, had advanced fibrosis, and had lower rates of previous treatment in comparison with undetectable HCV RNA. Overall treatment initiation was 70.4% and SVR was 72.8%. In the multivariable analysis, being screened in temporary housing (odds ratio [OR] 3.166; P = 0.002) and having opioid agonist treatment (OR 3.137; P = 0.004) were positively associated with treatment initiation. HCV treatment adherence (OR 26.552; P < 0.001) was the only factor associated with achieving SVR.DISCUSSION:Promoting education and having flexible and reflex mobile on-site testing and treatment for HCV in the homeless population improve engagement with the health care system, meaning higher rates of treatment initiation and SVR. However, street-based homeless population not linked with harm reduction services are less likely to initiate HCV treatment, highlighting an urgent need for a broad health inclusion system.
