HCUP Statistical Briefs present simple, descriptive statistics on a variety of topics including specific medical conditions as well as hospital characteristics, utilization, quality, and cost. HCUP databases can be purchased through the Online HCUP Central Distributor. The SEDD combined with SID discharges that originate in the emergency department are well suited for research and policy questions that require complete enumeration of hospital-based emergency departments within market areas or States. The State Emergency Department Databases (SEDD) are a set of databases that capture discharge information on all emergency department visits that do not result in an admission. State Emergency Department Databases (SEDD) In addition, some States provide data for ambulatory surgery and outpatient services from nonhospital-owned facilities. The State Ambulatory Surgery and Services Databases (SASD) include encounter-level data for ambulatory surgery and other outpatient services from hospital-owned facilities. State Ambulatory Surgery and Services Databases (SASD) Researchers and policymakers use the SID to investigate questions and identify trends unique to one State, to compare data from two or more States, and to conduct market area research or small area variation analyses. The State Inpatient Databases (SID) are a set of hospital databases containing the universe of the inpatient discharge abstracts from participating States, translated into a uniform format to facilitate multi-State comparisons and analyses. This database addresses a large gap in health care data-the lack of nationally representative information on hospital readmissions for all ages. The Nationwide Readmissions Database (NRD) is a unique and powerful database designed to support various types of analyses of national readmission rates for all payers and uninsured individuals. The NEDS enables analyses of ED utilization patterns and supports public health professionals, administrators, policymakers, and clinicians in their decisionmaking regarding this critical source of care. The Nationwide Emergency Department Sample (NEDS) captures information on emergency department (ED) visits that do not result in an admission as well as ED visits that result in an admission to the same hospital. Nationwide Emergency Department Sample (NEDS) Researchers and policymakers can use KID data to identify, track, and analyze health care utilization, access, charges, quality, and outcomes. The Kids' Inpatient Database (KID) is composed of hospital inpatient stays for children and is specifically designed to allow researchers to study a broad range of conditions and procedures related to children's health. Researchers and policymakers use NIS data to identify, track, and analyze trends in health care utilization, access, charges, quality, and outcomes. The National (Nationwide) Inpatient Sample (NIS) is the largest publicly available all-payer hospital inpatient care database in the United States. HCUP Databases National (Nationwide) Inpatient Sample (NIS) The HCUP databases are based on the data collection efforts of data organizations in participating States that have partnered with AHRQ. These databases enable research on a broad range of health policy issues, including cost and quality of health services, medical practice patterns, access to health care programs, and outcomes of treatments at the national, State, and local market levels. HCUP databases are derived from administrative data and contain encounter-level, clinical and nonclinical information including all-listed diagnoses and procedures, discharge status, patient demographics, and charges for all patients, regardless of payer (e.g., Medicare, Medicaid, private insurance, uninsured), beginning in 1988.
