Overview
Dataset Summary
The HCUP State Emergency Department Databases (SEDD) are part of the Healthcare Cost and Utilization Project (HCUP) and capture discharge information on all emergency department (ED) visits within participating states that do not result in hospital admission. These state-level administrative datasets include detailed information on diagnoses, procedures, patient demographics, expected payer, and charges, enabling analyses of ED utilization and patterns of care.
Caveats
- Includes only ED visits that do not result in hospital admission.
- ED visits resulting in admission are captured in the HCUP State Inpatient Databases (SID), not SEDD.
- As an administrative dataset, analyses depend on the accuracy of diagnosis and procedure coding.
- Availability and structure may vary by participating state.
Examples of Outcomes Examined
- Trends in ED use for selected conditions
- Healthcare access and utilization patterns
- Emerging infections and acute public health events
