Introduction Suffolk County, located in Eastern Long Island, has been an epicenter for the opioid epidemic in New York State, yet no studies have examined hepatitis C virus (HCV) prevalence in this population. Additionally, few studies have assessed barriers for linkage to care (LTC) to HCV treatment in people who inject drugs (PWID), a high-risk HCV cohort. We aimed to determine prevalence of HCV infection in a suburban medical center and to assess risk factors associated with LTC in HCV-positive baby boomers and young PWID. Methods A retrospective chart review was carried out on adult patients with ICD-9/10 diagnostic codes for HCV from January 2016 to December 2018 at Stony Brook Medicine. Data collected included sociodemographics, RNA serostatus, LTC, health insurance, employment, past medical or psychiatric history, and substance or injection drug use. Results Overall, 27,049 individuals were screened for HCV and 1017 were HCV seropositive (3.8%), 437 (42.9%) were HCV RNA-positive and 153 (40.6%) achieved LTC. In multivariate analysis, living with cirrhosis was associated with a positive LTC. Medicaid or Medicare insurance was associated with a negative LTC. Intravenous drug users were more likely to be young and have concomitant polysubstance use and psychiatric disease. A bimodal distribution of HCV-positives is present in our population. Conclusion Those with liver cirrhosis are more likely to achieve LTC, as are those with private insurance. Public health efforts to promote awareness of HCV and to facilitate access to treatment among PWID are needed.

BackgroundHuge efforts are being made to screen high-risk populations for Hepatitis C virus (HCV) infection, however linkage to care (LTC) rates remain low. The aim of this study was to assess the factors affecting LTC among HCV positives in a major tertiary academic medical center in eastern New York.MethodsA retrospective chart review was performed on all patients with ICD-9 or 10 diagnostic codes for HCV positive antibody over a period of 2 years (2016–2017) at Stony Brook Medicine. Data were collected for HCV RNA, LTC, demographics, type of insurance, employment status, psychiatric diagnosis, comorbidities, HIV or HBV coinfections, substance use disorder, and level of fibrosis. Univariate and multivariate analyses were performed to find associated factors with LTC.ResultsA total of 600 cases (62.6% male; 74% White; median age: 59 years) had a positive HCV antibody, 264 (44.4%) had a positive follow-up HCV RNA test and 138 (52.2%) were LTC. The average time for LTC was 1.5 months (50 days; interquartile range 21–121). In the univariate analysis, the following factors were significantly associated with LTC: older age (OR 1.022), having medicaid (OR 0.421), people who inject drugs (PWID) (OR 0.216), cocaine and marijuana use (OR 0.457), polysubstance use (OR 0.311), having a primary care provider (OR 2.290) and being a baby boomer (OR 1.718). The vast majority of patients came from three zip codes within south central Suffolk County, coinciding with the highest prevalence of heroin use.ConclusionIn this population insurance type, younger age and substance use (injection drugs, marijuana, cocaine, polysubstance) were associated with lower odds of LTC. Having a primary care provider and being a baby boomer were the only two independent risk factors associated with increased odds of LTC. Due to an increased number of HCV cases in younger populations, particularly PWID, further outreach efforts are urgently needed to spread HCV screening awareness and increase testing in high prevalence areas.Disclosures All authors: No reported disclosures.
