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?

The goal of the NDW is to load the data as it is sent to us. The data is not edited for validity. Thus the data is available ‘as is’ for IHS analyst review and analysis of data quality so that improvements may eventually be made at the source. The NDW performs scheduled data integrity checks on samples to ensure the NDW is storing data as it is received from the sites. Data quality reports are becoming available to inform our customers of possible data corrections, especially to improve the quality of workload and user population counts.

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?”
