The impact of diagnosis related group profitability on the skimming and dumping of psychiatric diagnosis related groups.

Psychiatric DRGs are identified in terms of their relative profitability within each hospital of a 386 hospital cohort. It is then determined whether hospitals admitted more of the more profitable and fewer of the less profitable patients over the period 1983-1987 (skimming). Also determined is whether hospitals discharged more of the less profitable to other short term hospitals over the same period of time (dumping). The findings generally indicate that this did not happen.
