HCUP Summary Trend Tables

The HCUP Summary Trend Tables include monthly information on hospital utilization derived from the HCUP State Inpatient Databases (SID) and HCUP State Emergency Department Databases (SEDD). Information on emergency department (ED) utilization is dependent on availability of HCUP data; not all HCUP Partners participate in the SEDD.

The HCUP Summary Trend Tables include downloadable Microsoft® Excel tables with information on the following topics:


For each type of inpatient stay, there is an Excel file for the number of discharges, the percent of discharges, the average length of stay, and the in-hospital mortality rate per 100 discharges.1 For each type of ED treat-and-release visit, there is an Excel file for the number of ED visits and the percent of ED visits. Within each Excel file there are State-specific worksheets with information on the monthly trends. For most files, the monthly trends begin in January 2017. Also included in each Excel file is a description of the HCUP databases and methodology.

Graphs from HCUP Summary Trend Tables

A focused report with graphs derived from Table 2d displays the monthly trends in the rate of in-hospital mortality per 100 discharges from January 2019 through June 2020 for nine States:

1 There is no Excel file for the in-hospital mortality rate for normal newborns, deliveries, and the service line of maternal and neonatal conditions because the rates are extremely low and have little variability over time.
