Hospital Utilization
In addition to the annual and quarterly financial reports, all non-federal hospitals licensed in California must submit an annual utilization report with the Office every February 15 for the prior calendar year’s data. Beginning in 2002, hospitals began submitting data to HCAI through an online reporting system. Once a report is submitted and meets edit criteria, it immediately becomes available to the public. After all individual hospital reports are received and approved, HCAI compiles the Hospital Annual Utilization Data Set from which the following products are produced.
Available Data Products
Complete Data Set
The complete Data Set of annual utilization data reported by hospitals contains basic licensing information including bed classifications; patient demographics including occupancy rates, the number of discharges and patient days by bed classification, and the number of live births; as well as information on the type of services provided including the number of surgical operating rooms, number of surgeries performed (both inpatient and outpatient), the number of cardiovascular procedures performed, and licensed emergency medical services provided. The documentation, including report forms, is available for each reporting year.
Important note about preliminary and final utilization data:
Starting with the 2005 annual utilization data file, there will be two phases of data released. The preliminary data file released in the spring will contain data that has passed the prescribed set of fatal errors in the SIERA system and was therefore accepted into HCAI. The second data file released in the fall will be the desk-audited data and is considered the final version of the annual utilization data file. Please note that this preliminary set of data will only be live and downloadable on the web page up and to the point that the final version is released and then the preliminary data file will be replaced by the final data file. The pivot tables will be created in the fall for the desk audited data.
Pivot Profiles
Pivot profiles were developed using the annual utilization data files aggregated for each report year. It displays a variety of data elements captured in the Annual Utilization Report of Hospitals.
