Abstract

Study objective

We describe the results of an emergency department (ED) hepatitis C virus testing program that integrated birth cohort screening and screening of patients with a history of injection drug use, as well as physician diagnostic testing, according to national guidelines.

Methods

We conducted a retrospective cohort study using data collected as part of clinical care. The primary outcome was the hepatitis C virus prevalence among tested patients. We evaluated factors associated with testing positive with logistic regression.

Results

Of the 26,639 unique adults aged 18 years or older and presenting to the ED during the 6-month study, 2,581 (9.7%) completed hepatitis C virus screening (2,028) or diagnostic testing (553), of whom 267 were antibody positive (10.3% prevalence). Factors associated with testing positive for hepatitis C virus included injection drug use (38.4% prevalence; odds ratio [OR] 10.8; 95% confidence interval [CI] 7.5 to 15.5), homeless (25.5% prevalence; OR 3.1; 95% CI 1.5 to 6.8), diagnostic testing (14.8% prevalence; OR 2.6; 95% CI 1.7 to 3.9), birth cohort (13.7% prevalence; OR 3.6; 95% CI 2.4 to 5.3), and male sex (12.4% prevalence; OR 1.4; 95% CI 1.0 to 2.0). Of the 267 patients testing positive for hepatitis C virus antibody, 137 (51%) had documentation of result disclosure and 180 (67%) had confirmatory ribonucleic acid testing performed, of whom 126 (70%) had a positive result. Follow-up appointments at the hepatitis C virus clinic were arranged for 57 of the 126 (45%) patients with confirmed positive results, of which 30 attended.

Conclusion

This ED screening and diagnostic testing program found a high prevalence of hepatitis C virus antibody positivity across all groups. Challenges encountered with hepatitis C virus screening included result disclosure, confirmatory testing, and linkage to care. Our results warrant continued efforts to develop and evaluate policies for ED-based hepatitis C virus screening.
