National Data Warehouse (NDW)  

Data Content

During the initial load of the data warehouse, NPIRS asked the sites to send all registration and encounter data dating back to October 1, 2000. Most sites were able to do so, but not all. Some also sent encounter data prior to that date, but this data is sparse.

Data includes (but is not limited to):

     Registration      Encounter
  • Patient identification
  • Chart numbers and locations
  • Address
  • Social Security Number
  • Tribal membership and benefit class
  • Insurance eligibility
  • Alias (AKA names)
  • Admission and discharge dates
  • Patient data
  • Location (Facility/clinic) of the service
  • Provider discipline
  • Procedure, diagnosis, injury and dental codes
  • Lab tests and clinical measurements
  • Health factors
  • Patient Education
  • Medication
  • Contract Health Service data such as authorization number, authorizing facility and cost

Please refer to the Meta Data and Standard Code Book tabs under this section for further information on those subjects.
Below are some commonly asked questions concerning data content within the NDW:

What standards do we adhere to/strive toward?
Is there a Thesaurus or other names for our fields?
Do we have registration/encounters with Temporary charts? How are they treated?
Do we have social security disability insurance (SSI) info?
Do we have demo patient encounter records?
Do we have the state in which a facility is located?
Do we have a variable that contains something like a “chart abstract?”
A chart abstract (synopsis of the conditions and problems of the patient) is not currently available in the NDW. It is on the list for possible future enhancements to the data that is maintained in the NDW.    [Close]
