Acute care hospitals are required to submit data on all inpatient discharges and outpatient surgeries. Legislators and policy makers use discharge and outpatient surgery statistics for public health planning, and legislation and policy development. Researchers use these statistics to understand trends and patterns of outpatient surgeries. Facilities use these statistics for their strategic planning and quality assurance purposes.

Acute care hospitals are required to submit data on all inpatient discharges for a calendar year by May 1st of the following year. The Division of Health Care Information uses the UB04 billing format to collect inpatient discharge data. Through OK2SHARE, access to inpatient discharges is available from 2002 to the most recently submitted and processed year. These data can be broken down by various demographics, including county, age, gender, race, admission source or point of origin, discharge status, principal diagnosis category, and major disease category. In addition to frequencies, charges (total and average total) and length of stay (total and average) can be calculated.

Statistics related to outpatient surgeries performed in acute care hospitals are available from 2006 to the most recently submitted and processed year. Acute care hospitals that perform outpatient surgeries are required to submit all outpatient surgery discharges for a calendar year by March 1st of the following year. Hospitals use the UB04 format to collect data on hospital outpatient surgery. Outpatient surgery statistics are available by year, county, gender, race, age, discharge status, payer group, body system and procedure group. In addition to frequencies of encounters, additional statistics are available for encounters including percent and charges (total, average, 25th percentile and 75th percentile); number and percent of procedures; and number and percent of patients.

Definitions of the data submitted from acute care hospitals can be found in the Data Submission ManualsExternal Link.
