[Economic consequences of complications in abdominal and thoracic surgery in the German DRG payment system].
BACKGROUND
The Surgical Department of the University Hospital Grosshadern has been making a systematic record of complications since 2005. With respect to the ongoing problem of under-financing from DRG reimbursements, an analysis of the relationship between surgical cases with severe complications and insufficient reimbursement warranted a detailed analysis.


METHODS
Out of 16 762 in-house patients during 2005-2007 we assigned 6707 cases into four divisions - hepato-pancreato-biliary, colorectal, minimal invasive and general abdominal surgery as well as 1469 cases of thoracic surgery, for costs and reimbursement. In all groups patients with mandatory treament of complications were compared to the remaining cases without complications. Within these, further subgroups were analysed: patients with a need for artificial ventilation (partition A of the G-DRG system), cases with excessive loss (underfunding above 10 000 Euro) and their intersections.


RESULTS
With the exception of minimal invasive surgery, each division featured 10-15 % of serious complications. Losses for these cases ranged from 159 % (thoracic surgery) to 102 % (other abdominal surgery) of the overall loss in each division. Cases with excessive losses, representing 1.5 % of all patients, caused 80 % to 100 % of this deficit. Complicated cases alloted to DRGs for artificial ventilation still represented 50 % of the under-fund-ing.


CONCLUSIONS
Cases with mandatory complication treatment can be discerned as separate economic entities. They are considerably overlapping cases with excessive underfunding, so further analysis might lead to an improved reimbursement policy. In addition, the connection between quality management and economic efficiency is highlighted.
