The Healthcare Cost and Utilization Project (HCUP) released four nationwide databases: the 2019 Kids’ Inpatient Database (KID), Nationwide Ambulatory Surgery Sample (NASS), Nationwide Emergency Department Sample (NEDS), and Nationwide Readmissions Database (NRD).
The KID is the largest publicly available all-payer pediatric inpatient care database that can be used to produce national estimates of hospital inpatient stays for children in the United States. Drawn from the HCUP State Inpatient Databases (SID), the KID includes more than 3 million pediatric hospital inpatient records from 48 States and the District of Columbia, covering 98 percent of the U.S. population.
The NASS produces national estimates of major ambulatory surgery encounters in hospital-owned facilities. The NASS contains clinical and resource-use information that is included in a typical hospital-owned facility record, including patient characteristics, clinical diagnostic and surgical procedure codes, disposition of patients, total charges, expected source of payment, and facility characteristics. Beginning with the 2019 data year, the NASS now includes information on patient race and ethnicity.
The NEDS generates national estimates about emergency department (ED) visits across the country. The NEDS describes ED visits regardless of whether they result in admission. One of the most distinctive features of the NEDS is its large sample size, which allows for analysis across hospital types and the study of relatively uncommon disorders and procedures. Beginning with the 2019 data year, the NEDS now includes information on patient race and ethnicity.
The NRD is designed to support various types of analyses of national readmission rates for all patients, regardless of the expected payer for the hospital stay. The NRD includes discharges for patients with and without repeat hospital visits in a year and those who have died in the hospital.
The HCUP NEDS CCR Files can be used to estimate how hospital charges translate into actual costs. Costs reflect the actual expenses incurred in the production of hospital services, such as wages, supplies, and utility costs. Hospital charges represent the amount a hospital billed for the case.
