Please see “Requesting OSHPD Patient Data Files” below for instructions.
Inpatient discharge or outpatient encounter visit records are reported on a scheduled basis for each time a patient is treated in a licensed general acute care hospital, emergency department, or ambulatory care surgery center in California. Facilities' data are reported via OSHPD's Medical Information Reporting for California System (MIRCal). This data includes patient demographic information, such as age, sex, county of residence and race/ethnicity; and clinical and administrative information, such as diagnosis, disposition, total charges and length of stay.
