Release Date: October 20, 2021

The Healthcare Cost and Utilization Project (HCUP) Nationwide Readmissions Database (NRD) featuring 2019 data is now available. The NRD is an annual database designed to generate national estimates of readmissions. The NRD includes discharges for patients with and without repeat hospital visits in a year and those who have died in the hospital. This database addresses a large gap in healthcare data—the lack of nationally representative information on hospital readmissions for all patients, regardless of the expected payer for the hospital stay.

The 2019 NRD uses the State Inpatient Databases (SID) from 30 States with verified patient linkage numbers that can be used to track a person across hospitals within a State, while adhering to strict privacy guidelines. Unweighted, the NRD contains data from approximately 18 million discharges each year. Weighted, it estimates roughly 35 million discharges in the United States.

The 2019 NRD can be purchased through the HCUP Central Distributor. Additional information is located on the NRD Overview Page.
