Insights
Hospital admissions present a missed chance for hepatitis C virus (HCV) care. Many patients with HCV coding were not tested or treated, highlighting the need for improved hospital pathways to link individuals to essential hepatitis C treatment.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Hospital admissions offer a critical, yet often missed, opportunity to connect patients with hepatitis C virus (HCV) to ongoing care and treatment.
- Current hospital systems may not effectively identify or engage individuals with HCV, leading to gaps in the care cascade.
Purpose of the Study:
- To determine the proportion of hospital inpatients and emergency department (ED) patients with hepatitis C who were linked to care and treatment.
- To identify specific hospital departments and patient pathways that could be optimized for HCV engagement.
Main Methods:
- Retrospective analysis of hospital databases (admissions, notifiable diseases, pharmacy) for adult patients with hepatitis C coding from March 2016 to March 2019.
- Examination of documented antibody and RNA testing rates, and direct-acting antiviral (DAA) prescription data.
- Comparison of HCV testing and linkage to care rates across different hospital departments.
Main Results:
- Of 2149 patients with hepatitis C coding, only 15.4% had antibody tests, 4.6% had RNA tests, and 8.3% received DAA prescriptions.
- Hepatitis specialist units showed high RNA testing rates (44.3%), while mental health had higher antibody testing (25.4%).
- Emergency departments had low antibody testing (13.7%) but the highest RNA detection rate (46.9%) among those tested.
Conclusions:
- Significant gaps exist in identifying and linking hospital patients with hepatitis C to care and treatment.
- Simplified diagnostic pathways, expanded HCV services, and clear in-hospital referral systems are crucial for improving the care cascade.
- Targeted interventions within hospital systems are necessary to scale up HCV testing and treatment for national elimination goals.
Abstract:
Hospital admissions are a missed opportunity to engage people living with hepatitis C virus (HCV) into care. This study aimed to describe the proportion of hospital inpatients and emergency department (ED) patients identified with hepatitis C who were subsequently linked to care and treatment at a metropolitan health service in Melbourne, Australia. Data were collected retrospectively from hospital databases (admissions, notifiable diseases, and pharmacy) for all adults admitted or attending the ED with separation coding indicating hepatitis C infection from March 2016 to March 2019. There were 2149 patients with at least one separation with hepatitis C coding. 15.4% (331/2149) had a documented antibody test, 4.6% (99/2149) had a documented RNA test, and 8.3% (179/2149) had a DAA prescription dispensed by hospital pharmacy. Antibody positivity was 95.2% (315/331) and RNA (when completed) was detected in 37.4% (37/99). Hepatitis specialist units had the highest rate of hepatitis C coded separations and RNA testing (39/88; 44.3%), mental health had the highest rate of antibody testing (70/276; 25.4%). Emergency had the lowest rate of antibody testing (101/1075; 13.7%) and the third highest rate of RNA testing (32/94; 34.1%), but the highest rate of RNA detected (15/32; 46.9%). This study highlights key steps to improve the care cascade. Simplified diagnostic pathways, expansion of hepatitis C care services, and clear in-hospital pathways to link patients to care would be beneficial in this setting. To scale up hepatitis C testing and treatment as part of national elimination strategies, hospital systems need to target interventions to their local data.
