  • Background:

    Only half of the 3.5 million individuals with chronic hepatitis C (HCV) in the US are aware of their infection. Emergency Departments (ED) provide a primary point of entry to the healthcare system for marginalized populations who are traditionally at elevated risk for HCV and are becoming an important venue for screening and linkage efforts. Optimal methods for HCV screening (universal vs. targeted) in ED remain undefined. We aim to ascertain the relative prevalence of HCV infection by age and other risk factors through non-targeted screening for HCV in our high-volume urban ED.


    In this ongoing prospective observational cohort study, consenting adult ED patients participate in a researcher-administered structured interview and are offered a rapid HCV antibody (HCV Ab) screening test. If reactive, confirmatory serologic HCV Ab and HCV RNA are sent immediately and a clinic appointment is scheduled within 4 weeks. Participants are contacted with HCV RNA PCR results; those with detectable viral load are encouraged to attend follow-up appointment and receive a reminder call one week prior to appointment. Successful linkage to care is defined as appointment attendance.


    2018 eligible patients were approached July 2015-April 2016. 732 participated in a structured interview. 707 accepted an HCV Ab rapid test. HCV antibody prevalence in the ED was 3.8% (0.43% in non-baby boomers without injection drug use (IDU), 7.6% in baby boomers, 34% in persons endorsing IDU). 23 HCV Ab reactive participants submitted blood for confirmatory testing. 12/23 (52%) had detectable HCV RNA, corresponding to 1.7% prevalence of chronic infection. Targeted screening of the birth cohort and those with IDU would have missed 7.4% (2/27) of HCV Ab positive patients and 8.3% (1/12) with chronic infection. 4/12 (33.3%) with chronic infection were linked to care, 2 have upcoming appointments, 1 died before appointment.


    Prevalence of HCV in our ED was higher than the national estimate of 3.4% among baby boomers used to justify national birth cohort screening. Optimal ED HCV screening methods should target baby boomers and those endorsing IDU, but a modest proportion of infections will be missed without universal screening.
