BackgroundLimited data exists concerning the health economics of liver resection, with even less information on the costs emerging from complications, despite this remaining an important target from a health economic perspective. Our objective was to describe the financial burden of complications following liver resection.MethodsWe conducted a systematic search and included studies reporting resource use of in-hospital complications during the index liver resection admission. All indications for liver resection were considered. All techniques were considered. Data was collected using a data extraction table and a narrative synthesis was performed.ResultsWe identified 12 eligible articles. There was considerable heterogeneity in study designs, patient populations and outcome definitions. We found weak evidence of increased costs associated with major liver resection compared to minor resections. We found robust evidence supporting the increasing economic burden arising from complications after liver resection. Acceptable evidence for increased cost due to the presence and grade of complication was found. Strong evidence concerning the association of length of stay with costs was demonstrated.ConclusionsThe presence and grade of complications increase hospital cost across diverse settings. The costing methodology should be transparent and complication grading systems should be consistent in future studies.© 2019 Royal Australasian College of Surgeons.
