Submit Patient-Level Administrative Data
About Us
To meet California’s needs in making informed decisions and through partnerships with healthcare facility data providers, HCAI has been collecting quality, timely, secure, and comprehensive 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. Data are submitted via HCAI’s secure data collection system.
