Background: Direct acting antivirals (DAAs) have simplified and expanded access to Hepatitis C virus (HCV) treatment. Only 17% of the 2.4 million Americans with HCV have linked to HCV care. We aimed to evaluate linkage to care (LTC) in a non-urban HCV referral clinic with a nurse navigator model and identify disparities in LTC.Methods: A single-center retrospective cohort analysis was performed among all patients referred to an infectious diseases HCV clinic between 2014 and 2018. The primary outcome was LTC, defined as attendance at a clinic appointment. A multivariable Poisson regression model estimated the association of variables with LTC.Results: Among 824 referred patients, 624 (76%) successfully linked to care and 369 (45%) successfully achieved sustained virologic response. Forty-six percent of those referred were uninsured. On multivariable analysis, LTC rates were higher among women (Incidence Rate Ratio [IRR] 1.11, 95% CI 1.03–1.20, p-value = 0.01) and people with cirrhosis (IRR 1.20, 95% CI 1.11–1.30, p-value < 0.001). Lower LTC rates were found for young people (<40 years; IRR 0.88, 95% CI 0.79–0.98, p-value = 0.02) and uninsured people (IRR 0.85, 95% CI 0.77–0.94, p-value = 0.002). Among those without LTC, 10% were incarcerated. Race, proximity to care, substance use, and HIV status were not associated with LTC.Conclusions: Using an embedded nurse navigator model, high LTC rates were achieved despite the prevalence of barriers, including a high uninsured rate. Disparities in LTC based on age, sex, and insurance status are present. Substance use was not associated with LTC. Future interventions to improve care should include expanded access to insurance and programs bridging care for incarcerated populations.

Background Most people diagnosed with hepatitis C virus (HCV) have not linked to care, despite the availability of safe and effective treatment. We aimed to understand why people diagnosed with HCV have not pursued care in the non-urban Southern United States. Methods We conducted a survey and semi-structured interview with participants referred to an HCV clinic who did not attend an appointment between 2014 and 2018. Our clinic is located in a non-urban region of Virginia at a university hospital. Qualitative data collection was guided by the Health Belief Model (HBM). Data was analyzed using qualitative content analysis to identify key factors influencing patient perceptions regarding HCV and pursuit of care. Results Over half of previously referred patients (N = 200) could not be reached by phone. Eleven participants enrolled, including 7 men and 4 women. Based on survey responses, unreliable transportation, unstable housing, substance use, and lack of insurance were common. Participants demonstrated good knowledge of HCV disease, complications, and treatment. On qualitative analysis of semi-structured interviews, final themes emerged from within and between HBM constructs. Emerging themes influencing patient perceptions included (1) structural barriers, (2) stigma, (3) prior experiences of HCV disease and treatment, (4) discordance between the recognized severity of HCV and expected impacts on one’s own health, and (5) patient-provider relationship. Substance use was not identified to be a barrier to care. Conclusions Participants perceived individual and structural barriers to linking to care. A strong HCV knowledge base was not sufficient to motivate pursuit of care. Efforts to improve linkage to care must address barriers at multiple levels, and system-level changes are needed. As the majority of previously referred patients could not be contacted by phone, current approaches to patient engagement are not effective for reaching these populations. Expansion of HCV care to primary care settings with an established patient-provider relationship or co-located treatment within substance use treatment programs may serve to increase access to HCV treatment.

BackgroundHepatitis C is now curable for most individuals, and national goals for elimination have been established. Transmission persists, however, particularly in nonurban regions affected by the opioid epidemic. To reach goals of elimination, barriers to treatment must be identified.MethodsIn this open cohort of all individuals diagnosed with active hepatitis C from 2010 to 2016 at a large medical center, we identified patient and clinic characteristics associated with our primary outcome, sustained virologic response (SVR). We performed a subgroup analysis for those with documented substance misuse.ResultsSVR was achieved in 1544 (41%) of 3790 people with active hepatitis C. In a multivariable Poisson regression model, SVR was more likely in individuals diagnosed outpatient (incident rate ratio [IRR], 1.7; 95% confidence interval [CI], 1.5–2.0), living in close proximity to the medical center (IRR, 1.2; 95% CI, 1.1–1.3), with private insurance (IRR, 1.1; 95% CI, 1.0–1.3), and with cirrhosis (IRR, 1.4; 95% CI, 1.3–1.5). Achieving SVR was less likely in those qualifying as indigent (IRR, 0.8; 95% CI, 0.8–0.9) and those with substance misuse (IRR, 0.8; 95% CI, 0.7–0.9). In the subgroup analysis of those with substance misuse, SVR rates were higher in those linked to the infectious diseases clinic, which has embedded support services, than those linked to the gastroenterology clinic, which does not (IRR, 1.4; 95% CI, 1.1–1.9).ConclusionsSocial determinants of health including proximity to care and poverty impacted achievement of SVR. Those with substance misuse, a high-priority population for treatment of hepatitis C, had better outcomes when receiving care in a clinic with embedded support services.

Background Hepatitis C virus (HCV) and the opioid epidemic disproportionately affect the Appalachian region. Geographic and financial barriers prevent access to specialty care. Interventions are needed to address the HCV-opioid syndemic in this region. Methods We developed an innovative, collaborative telehealth model in Southwest Virginia featuring bidirectional referrals from and to comprehensive harm reduction (CHR) programs and office-based opioid therapy (OBOT), as well as workforce development through local provider training in HCV management. We aimed to (1) describe the implementation process of provider training and (2) assess the effectiveness of the telehealth model by monitoring patient outcomes in the first year. Results The provider training model moved from a graduated autonomy model with direct specialist supervision to a 1-day workshop with parallel tracks for providers and support staff followed by monthly case conferences. Forty-four providers and support staff attended training. Eight providers have begun treating independently. For the telehealth component, 123 people were referred, with 62% referred from partner OBOT or CHR sites; 103 (84%) attended a visit, 93 (76%) completed the treatment course, and 61 (50%) have achieved sustained virologic response. Rates of sustained virologic response did not differ by receipt of treatment for opioid use disorder. Conclusions Providers demonstrated a preference for an in-person training workshop, though further investigation is needed to determine why only a minority of those trained have begun treating HCV independently. The interdisciplinary nature of this program led to efficient treatment of hepatitis C in a real-world population with a majority of patients referred from OBOTs and CHR programs.

Despite ambitious goals to eliminate hepatitis C virus (HCV) in the United States by 2030, the majority of those infected are not aware of their diagnosis, and only a small minority have been cured. A lack of knowledge regarding risk factors and treatment may contribute to low cure rates. We aimed to evaluate HCV knowledge and the association of risk factor knowledge with HCV incidence. In fall 2017, a survey regarding HCV knowledge was disseminated through social media, web link, and in person throughout the state of Virginia. The survey was completed by 613 individuals. Residents of high-incidence counties identified fewer risk factors (5.6 vs 6.1 of 9, p = 0.04), a difference that remained significant when controlling for education and age (p = 0.03). Fewer participants in the high-incidence group recognized snorting drugs to be a risk factor (25% vs 36%, p = 0.01). Only 38% of all respondents correctly identified HCV to be curable. Knowledge of HCV risk factors is lower in high incidence regions. These results identify a critical knowledge gap in the general population at a time of ongoing HCV transmission. Public health interventions must target these gaps in high-incidence regions as part of comprehensive disease prevention programs.
