ARTICLE HIGHLIGHTS
Research background
The incidence, morbidity, and mortality related to liver disease is not well understood.
Research motivation
To develop a national liver disease registry to inform the provision of hepatology services.
Research objectives
Develop and apply a novel methodology for a national liver registry incorporating aetiology, stage and mortality related to liver disease.
Research methods
Novel methodology for developing a national liver registry using routinely coded secondary care and death certificate datasets.
Research results
The incidence of liver disease has increased 3.6-fold in Wales between 1999-2019 driven by a 10-fold increase in non-alcoholic fatty liver disease (NAFLD) 3-fold increase in cirrhosis, portal hypertension, decompensation and hepatocellular carcinoma, 2-fold increase in liver disease related mortality between 1999-2019. Actuarial tables of 10-year liver disease progression: Alcohol-related liver disease, autoimmune liver disease and congestive hepatopathy are associated with increased rates of decompensation and death compared to viral hepatitis and NAFLD.
Research conclusions
The Wales Liver Registry methodology provides a novel approach to understand the progression of liver disease in the setting of a rapidly altering incidence of liver disease in Wales.
Research perspectives
We have developed an analytic pipeline and will using this methodology to assess the impact of improvements in service provision.
