A two-year analysis of DRG #288, procedures for obesity.

DRG #288 is composed of operative procedures performed for obesity, both gastric and plastic. A two-year cost analysis of 103 consecutive gastric reduction operations performed for morbid obesity was conducted at Robert Wood Johnson University Hospital. It showed a net loss to the hospital of $18,033 in 1984 and $24,126 in 1985. Although the mean length of stay was 1.43 days less in 1985 than in 1984, DRG #288 was still a money loser. A detailed cost breakdown of nine active cost-center categories showed large financial disincentives (losses) in surgical supplies, OR/recovery room time and X ray utilization during both years of the study. These losses were not offset by substantial profits in the room-and-board category, which is directly related to length of stay. It is intuitively obvious that plastic surgical procedures for obesity require less expensive surgical supplies, fewer X rays, and shorter OR/recovery room times than gastrointestinal operations performed for morbid obesity. We conclude that DRG #288 is improperly constructed because it contains a clinically incoherent, heterogeneous mixture of operations that cannot be expected to consume similar amounts of resources and incur similar costs. Hospitals in which the preponderance of operations performed for obesity are gastrointestinal as opposed to plastic are inherently penalized by the current aggregation of DRG #288.
