Differences in inpatient and outpatient hepatitis C virus prevalence and linkage to care rates in a safety net hospital hepatitis C screening program.

BACKGROUND AND AIM: Routine screening for hepatitis C virus (HCV) infection is crucial in identifying the 50% of infected persons unaware of their infection. We added an inpatient screening initiative to our successful outpatient HCV screening program in an urban, safety-net hospital. METHODS: From March 2017 to December 2019, HCV screening was performed in inpatient and outpatient settings at Grady Health System. We compared care cascade outcomes, including anti-HCV testing, RNA testing, and linkage to care (LTC) between these settings. RESULTS: A total of 29 751 patients were tested for anti-HCV: 8883 inpatients and 20 868 outpatients. The anti-HCV population was predominantly Black (76.2%) and male (67.9%). The total anti-HCV prevalence was 8.9%, with 14% of inpatients and 6.7% of outpatients testing positive. RNA testing was performed on 86%. The prevalence of active HCV infection was 59.3% in those that were anti-HCV positive; inpatient prevalence was 66%, and outpatient was 53.8%. Of those with active infection, 67.5% were linked to care (57.3% of inpatients and 77.8% of outpatients). CONCLUSION: We found significant differences in prevalence of anti-HCV and LTC rates between inpatients and outpatients during an HCV screening program. Higher anti-HCV prevalence among inpatients may be due a higher prevalence of non-birth year HCV risk factors. LTC rates were lower in the inpatient setting despite a robust linkage strategy. The striking prevalence of HCV in both settings warrants continued screening, expansion to additional settings, and novel strategies to improve inpatient linkage rates, especially in the setting of new universal HCV screening guidelines.

High-Yield Birth-Cohort Hepatitis C Virus Screening and Linkage to Care Among Underserved African Americans, Atlanta, Georgia, 2012-2013.

OBJECTIVE: Hepatitis C virus (HCV) infection disproportionately affects certain populations, including those born between 1945 and 1965 (i.e., baby boomers) and African Americans. As part of the Hepatitis Testing and Linkage to Care initiative, which promoted hepatitis B and hepatitis C screening, posttest counseling, and linkage to care at 34 U.S. sites, we conducted routine HCV screening to identify previously undiagnosed, primarily African American baby boomers with chronic hepatitis C infection and link them to care. METHODS: We launched the Internal Medicine Trainees Identifying and Linking to Treatment for Hepatitis C (TILT-C) initiative at the Grady Memorial Hospital Primary Care Center and Grady Liver Clinic in Atlanta, Georgia, in October 2012, and present results from the first year. TILT-C faculty implemented an electronic medical record prompt and conducted educational sessions to boost HCV screening. A project coordinator tracked testing outcomes and linked HCV-positive patients to care. RESULTS: Of 2,894 patients tested for anti-HCV, 201 (6.9%) tested positive. Men had a significantly higher (p<0.001) prevalence of HCV infection than women, with 106 of 1,091 (9.7%) men compared with 95 of 1,803 (5.3%) women testing anti-HCV positive. A total of 174 of 201 (86.6%) anti-HCV-positive patients received HCV ribonucleic acid (RNA) testing. Of 124 patients with a positive HCV RNA test, 122 were referred to care and 120 attended the first appointment. CONCLUSION: The TILT-C screening program was feasible and effective in detecting previously undiagnosed HCV infection and linking patients to care. The unexpectedly high prevalence of HCV infection in this primarily African American, baby boomer population underscores the need for aggressive HCV screening efforts in similar populations.
