Description of intervention(s) / exposure
Retrospective analysis of all admissions with acute cholangitis between January 2010 and December 2016. Each admission was categorised according to underlying aetiology, presence of biliary stent, choledocholithiasis, previous endoscopic biliary manipulation, immunosuppression, liver transplantation and representation. Each category was compared in relation to the pathogens grown, in-hospital length of stay (LOS) and Intensive Care Unit length of stay (ICU-LOS).

Summary
Brief summary
Australian data on pathogens causing acute cholangitis is lacking. Americian, European and Asian data state that E.Coli, Klebsiella species and Enterococcus species are the three most common pathogens causing acute cholangitis. This study aims to identify pathogens causing acute cholangitis from positive blood cultures in an Australian setting as a guide to antibiotics selection and to analyse their impact on in-hospital length of stay (LOS).
