Abstract
Persons with chronic hepatitis C (HCV) infection are at increased risk of end-stage liver disease (ESLD) and hepatocellular carcinoma (HCC). The impact of hepatitis treatment scale-up and elimination strategies on ESLD and HCC incidence is a critical measure of progress towards WHO targets. Data from national laboratory surveillance of HCV diagnoses were linked to inpatient care records in Hospital Episode Statistics (HES). For persons first diagnosed with HCV between 1998-2016, we describe the characteristics of those with ESLD and HCC and estimate incidence. Of persons diagnosed with HCV between 1998 and 2016 (104,674), 9.1 % (9,525) had an admission for ESLD and 2.5% (2,610) for HCC. The majority of persons with ESLD and HCC were male (70.7% and 82.7%) and of white ethnicity (89.9% and 82.7%). Crude incidence of ESLD and HCC admission was 10.4 and 3.2 per 1,000 person years respectively. When compared to 2011-2013, incidence of ESLD and HCC admissions in 2014-2017 were lower [ESLD incidence rate ratio (IRR): 0.81; 95% Confidence interval (CI): 0.76-0.86; HCC IRR: 0.90; 95% CI: 0.82-1.00, p=0.045]. Data linkage showed considerable underreporting of HCV in HES coding for ESLD and HCC (16.0% and 11.3% respectively). In conclusion, we found a decline in incidence of ESLD and HCC-related inpatient admissions since 2011-2013. Linked analysis is required for the continued monitoring of ESLD and HCC inpatient incidence. However, HES data quality issues around completeness of identifiers contribute to uncertainty in linkage and may limit our ability to robustly monitor progress towards WHO elimination goals.
