North Carolina Hospital Discharge Data
Prior to 1995, the Medical Database Commission (MDC) collected hospital discharge data. On September 31, 1995, the North Carolina General Assembly eliminated the MDC and set up an alternative system for the reporting of discharge data. Since 1996, hospitals have reported data to a Statewide Data Processor (currently Truven Health Analytics) as set forth by the Medical Care Data Act of 1995 (Article 11a of Chapter 131E of the North Carolina General Statutes).
Since 1996, the Cecil G. Sheps Center for Health Services Research has worked under contract with the North Carolina Division of Health Services Regulation (DHSR) to store, maintain and analyze the NC Discharge databases. These databases are not public records, but are available for research.
Data variables include patient characteristics, clinical information such as diagnosis and procedure codes and length of stay, payer information, charge information, admission source and patient status.
Variables are not always consistent from year to year. Hospitals were not required to report race and ethnicity data until 2011; concerns remain about the accuracy of these data.
