SID

HCUP databases contain patient-level information compiled in a uniform format with privacy protections in place. The State Inpatient Databases is one of the databases included in HCUP. It covers inpatient care in community hospitals in 22 States that represent more than half of all U.S. hospital discharges. SID contains the universe of that State's hospital inpatient discharge records. They are composed of annual, State-specific files that share a common structure and common data elements. SID is a set of hospital databases from data organizations in 22 participating States. It contains more than 100 clinical and nonclinical variables: principal and secondary diagnoses, principal and secondary procedures, admission and discharge status, patient demographics (e.g., gender, age, and, for some States, race), expected payment source (e.g., Medicare, Medicaid, private insurance, self-pay; for some States, additional discrete payer categories, such as managed care), total charges, length of stay, hospital and county identifiers that permit linkage to the American Hospital Association Annual Survey File and the Area Resource File.

SID consists of individual data files from Data Organizations in 22 participating States. In general, the SID contains the universe of that State's hospital inpatient discharge records. They are composed of annual, state-specific files that share a common structure and common data elements. The hospitals included in the SID depend on the information provided by the Data Organizations. Most State government Data Organizations provided information on all acute care hospitals in the respective State. Private Data Organizations are often restricted to member hospitals and may not provide information on all hospitals in their State.

HCUP includes 2 other databases: the Nationwide Inpatient Sample (NIS) and the State Ambulatory Surgery Databases (SASD). NIS includes inpatient data from a national sample of over 1,000 hospitals. The SASD, the project's newest restricted access public release, contains data from ambulatory care encounters in 9 States.
