Patient-level administrative data abstracted from individual patient records and facility-level utilization data on healthcare services from hospitals and healthcare facilities.
Patient-Level Administrative Data
HCAI has been collecting inpatient discharges since 1983 – and emergency department and ambulatory surgery encounters, from both hospital-based ambulatory surgery centers and licensed freestanding ambulatory surgery clinics, since 2005.
Facilities submit abstracted information from individual patient records that include data such as the patient’s ZIP code, birthdate, preferred language, diagnoses, treatments/procedures, total charges, and expected source of payment. To protect individual patient confidentiality, any publicly available data are aggregated into data products that are available on an annual basis.
