Note: Percents shown above are percentages of diagnosis-specific discharges. Weighted estimates from HCUP Nationwide Inpatient Sample (NIS), 2004, Agency for Healthcare Research and Quality, based on data collected by individual States and provided to AHRQ by the States. The total number of weighted adult discharges in the U.S. is based on HCUP NIS=31,928,948. Statistics based on estimates with a relative standard error (standard error/weighted estimate) greater than 0.30 or with standard error = 0 are not reliable. These statistics are suppressed and are designated with an asterisk (*).
