Hepatitis C virus (HCV) infection is a public health threat. The electronic health record (EHR) can be used to monitor patients along the HCV cure cascade and highlight opportunities for interventions to improve cascade outcomes. We developed an HCV patient registry using data from Grady Health System's (GHS) EHR and performed a cross‐sectional analysis of 72 745 GHS patients who received anti‐HCV testing from 2004 to 2016. We created a testing cascade: (1) anti‐HCV reactive, (2) HCV RNA tested and (3) HCV RNA detectable; and a cure cascade: (1) HCV RNA detectable, (2) engaged in care, (3) treatment prescribed, (4) sustained virologic response (SVR) tested and (5) SVR documented. A total of 9893 (14%) had reactive anti‐HCV tests of 72 745 patients tested, 5109 (52%) of these had HCV RNA tested, and 4224 (43%) were HCV RNA detectable. A total of 2738 (65%) of 4224 with detectable RNA were engaged in care, 909 (22%) were prescribed antiviral therapy, and 354 (8%) achieved SVR. Factors associated with HCV treatment included cirrhosis, tobacco use, depression, diabetes, obesity, alcohol use, male gender, black race and Medicare insurance. Uninsured patients were significantly less likely to be prescribed HCV treatment. In conclusion, using EHR data, we identified high anti‐HCV prevalence and noted gaps in HCV RNA testing, linkage to care and treatment. The EHR can be used to evaluate the effectiveness of targeted interventions to overcome these gaps.

Objectives: We compared outcomes of the hepatitis C virus (HCV) cure cascade (ie, the path a patient follows from diagnosis to cure), including antiviral treatment outcomes, from 2 HCV screening programs. Our objective was to assess whether treatment uptake and HCV cure rates improved in the cohort screened after the release of all-oral HCV direct-acting antiviral therapies. Methods: We retrospectively compared outcomes of the HCV cure cascade from a cohort of newly diagnosed patients screened during 2012-2014 (period 1) with outcomes from a cohort of newly diagnosed patients screened during 2015-2016 (period 2) at Grady Health System in Atlanta, Georgia. Cure cascade outcomes included HCV antibody (anti-HCV) and RNA testing, linkage to care, antiviral treatment, and sustained virologic response. Results: During period 1, 412 of 5274 (7.8%) persons screened were anti-HCV positive, and 264 (69.3%) of those tested were RNA positive. During period 2, 462 of 7137 (6.5%) persons screened were anti-HCV positive, and 240 (59.3%) of those tested were RNA positive ( P = .003). The percentage of newly diagnosed patients who were treated during period 2 (64.0%) was 3 times that of newly diagnosed patients treated during period 1 (21.2%; P < .001). Both cohorts had similarly high levels of linkage to care (95.8% during period 1, 95.4% during period 2) and cure (92.6% during period 1, 95.5% during period 2). Conclusions: Over time, the prevalence of anti-HCV and HCV RNA positivity declined substantially, and linkage-to-care and cure rates remained high. Treatment uptake increased significantly after the introduction of all-oral direct-acting antiviral therapy. These findings suggest that combining large-scale screening initiatives with treatment programs can speed progress toward HCV elimination.
