Emergency Department Encounters
On a quarterly basis (every three months), emergency departments submit abstracted information from individual patient records which include data on the patient’s ZIP code, birthdate, preferred language, service date, diagnoses, external cause of injury/morbidity, treatments/procedures, and expected source of payment. To protect individual patient confidentiality, data are aggregated into data products which are available on an annual basis.

Patient Origin/Market Share Pivot Table#
This product contains the Patient Origin and Market Share Pivot Tables. These pivot tables identify where in the state (specified by ZIP Code) patients come from for treatment at a selected hospital, as well as the hospitals that patients from a selected ZIP Code or county go to for treatment.
Pivot Profile#
This pivot profile was developed using the emergency department data file and the inpatient discharge data file (for admissions originating in the emergency department) aggregated at the hospital level. The summary data include number of visits, expected payer, discharge disposition, age groups, sex, preferred language spoken, race groups, principal diagnosis groups, and principal external cause of injury/morbidity groups. The data can also be summarized statewide or for a specific hospital county, ED service level, teaching/rural status, and/or type of control.
Facility Summary Reports#
Patient-level data reported by an individual facility is displayed in its Facility Summary Report. The Summary Report presents a calendar year overview, with numerical and percentage breakdowns of reported data categories or groups, for the selected facility. Regulatory requirements are based on the facility’s state licensure; report availability is therefore dependent on licensure. Reports are made available pursuant to Health and Safety Code Section 128755 (c) (3), (d), and (e).
