[Possibilities and limitations for the representation of ENT medicine in the G-DRG reimbursement system. Results of the DRG evaluation project].
BACKGROUND
To improve the representation of ENT medicine in the German diagnosis related groups (G-DRG) reimbursement system, the German Association for ENT Medicine and the ENT Professional Medical Association, in cooperation with the DRG-Research Group of the University Hospital of Muenster, undertook a DRG evaluation project.


METHODS
A retrospective analysis was carried out of the DRG data records from 93,605 cases taken at 39 ENT institutions in 2003. A prospective collection of data from 25,666 cases, including defined expenditure data within a 4 month period in 2004, was also made.


RESULTS
The number of cases per ENT institution ranged from 274 to 2,556. The mean case-mix was 792.0 and the mean case-mix index was 0.84. A total of 60.5% of the patients were male and 39.5% female, with an average age of 43.3 years. The mean patient clinical and complexity level (PCCL) was 0.72. Considerable adjustments have to be made, especially in oto-, rhino- and sinus-surgery. Allocation according to the complexity of the surgical procedure is mandatory and requires a revision of the German Catalogue of Medical Procedures. A DRG differentiation based on the PCCL should be implemented more frequently. Diagnostic endoscopies should be allocated via surgical partitioning.


CONCLUSIONS
The adjustment proposals based on these results will gradually lead to an improved allocation of ENT medical procedures within the G-DRG system in 2006 and later.
