General Notes
 

Disease Staging was assigned using software developed by Medstat. Starting with the 2008 NIS, this data element is unavailable because it was discontinued as part of the Disease Staging software. This severity measure includes the disease category and stage for the principal diagnosis and predictive scales for mortality, length of stay, and total charges. The prefix "DS_" has been included in the data element name to distinguish the Disease Staging measures from other HCUP data elements. For more information, please refer to the following documents available on the NIS Documentation CD-ROM and on the HCUP User Support Website (www.hcup-us.ahrq.gov):
