The report, which covers inpatient hospital discharges during 1998, is divided into three regional versions. The information reported is hospital-specific.

The report encompasses 15 selected Diagnosis Related Groups (DRGs). These DRGs have been chosen due to a combination of factors, including a high degree of variation in mortality, high volume, significant resource consumption, and diversity across diagnoses and procedures. These DRGs represent approximately 15% of all hospital discharges statewide. A description of the DRGs can be found on page 6.

All Pennsylvania general and most specialty acute care hospitals, regardless of bed size, are included. The number of cases, a risk-adjusted mortality rating, a risk-adjusted average length of hospital stay, and the average hospital charge for each of the 15 DRGs form the basis of the report.
