Og = the number of discharges with disposition of "deceased." pg = the number of all discharges in DRGs with less than 5% mortality rate based on National Inpatient Sample data for 1997 (United States). 

In partnership with data organizations in 37 states, AHRQ sponsors the Nationwide Inpatient Sample (NIS), a data bank of the Healthcare Cost and Utilization Project (HCUP). The HCUP is a federal-state-industry partnership that provides all discharge-related data from over 990 hospitals (i.e., about 8 million annual hospital stays) [5]. The NIS is the largest all-payer inpatient care data bank in the United States, and it can be used to derive national estimates of inpatient care. By using the data from this data bank, the AHRQ has been able to provide complication rates and risk-related data, even for quife rare surgical procedures, such as bariatric surgery [6].
