OpenCodelists

Welcome to OpenCodelists, created by OpenSAFELY for creating and sharing codelists.

Anybody can also use this tool to create and share codelists. To get started, take a look at the documentation or watch the videos.

If you would like to publish codelists on behalf of an organisation, please get in touch.

Below, you'll find all the codelists we have used in OpenSAFELY research to date.

Advanced decompensated cirrhosis of the liver and associated conditions (snomed) SNOMED CT

Codelist to identify patients with advanced decompensated cirrhosis of the liver and severe liver disease.

Decompensated cirrhosis is defined as an acute deterioration in liver function in a patient with cirrhosis and is characterised by jaundice, ascites, hepatic encephalopathy, hepatorenal syndrome or variceal haemorrhage. (Moreau et al, 2013)

The codelist takes into account the conditions which characterise advanced decompensated cirrhosis of the liver listed above as well as the code for cirrhosis.

NOTE: This version has taken out codes related primary biliary cirrhosis as our study used this study population and we used the codelist to identify severe disease. We have also added some terms to make sure we capture all severe disease such as HCC and gastric varicies. The update was carried out with Dr Karen Waller at the University Sydney.
