Summary Background Proton pump inhibitor ( PPI ) therapy has been reported to be an independent mortality risk factor in patients with cirrhosis. Aim To identify the prevalence of PPI prescription, the appropriateness of this therapy and to investigate the relationship between PPI therapy and overall survival in patients with liver disease. Methods This retrospective cohort study used patient data for 2012 to 2014 collected from the Scottish Liver Transplant Unit and the Hepatology Ward at the New Royal Infirmary of Edinburgh. Results A total of 64% of the 198 patients discharged from the Hepatology ward were prescribed a PPI . Of the 206 patients assessed and listed for orthotopic liver transplant ( OLT ), 55% were prescribed a PPI . These percentages are significant, particularly as the majority had no recorded appropriate indication for this therapy. For patients listed for OLT , a logistic regression model revealed significant associations between PPI treatment and male sex, higher model of end‐stage liver disease ( MELD ) scores and patient encephalopathy. A multivariate Cox regression model showed that MELD and UK model for end‐stage liver disease scores were independent predictors of patient mortality, while alcoholic liver disease aetiology was a protective factor. There was no statistically significant difference in survival between patients who were prescribed a PPI at assessment and those who were not. Conclusion Associations between PPI use, encephalopathy and higher MELD scores imply caution should be exercised in prescribing gastric acid suppressants to patients with cirrhosis, particularly in the absence of clear indications.
