DSHOSPID - Data source hospital number

General Notes
 

There are up to three different types of hospital identifiers included in the HCUP databases.

  • The data source's own number scheme for identifying hospitals and facilities (DSHOSPID),
  • The hospital identifier used by the American Hospital Association (AHAID and IDNUMBER), and
  • A unique HCUP hospital identifier (HOSPID).

The hospital entity as defined by the data source may differ from the hospital entity as defined by the American Hospital Association. For example, the data source treats two separate facilities as two hospitals, while the AHA Annual Survey treats the two facilities as a single hospital, or vice versa. For consistency across states, HCUP defines hospitals in accordance with the AHA Annual Survey of Hospitals. During the creation of the HCUP AHA Linkage Files, the data source's identification of the hospital is reconciled with the identification of the hospital in the AHA Annual Survey of Hospitals. For detailed information about this linking process, see the special report on HCUP Hospital Identifiers.

Warning to data users: DSHOSPID is a character variable that may have different lengths in different HCUP state databases and years. When combining data across states and years, care needs to be taken to retain the values in the longest length of DSHOSPID. For example, in SAS, if the dataset with a DSHOSPID of length character 4 is listed first in the set or merge statement with a dataset containing a longer length DSHOSPID, SAS will use the first length (character 4) for the output file. The longer DSHOSPIDs will be truncated and contain the leftmost 4 characters of the DSHOSPID.

The data element DSHOSPID is available in the Core and Hospital file.

State Specific Notes

Arizona

If you need identifying information on Arizona hospitals beyond that which is provided in the HCUP documentation, please contact the State agency directly: Donna Courtney, Arizona Department of Health Services, courtnd@azdhs.gov.



Florida

DSHOSPID values with 1, 2, 3, or 6 digits were padded with zeros for a total of 8 digits.



Iowa

In 1996 only, Iowa includes some discharges from facilities in Illinois, Missouri, Nebraska, South Dakota, and Wisconsin. These out-of-state facilities can be separated from Iowa facilities by their five-digit DSHOSPIDs; Iowa facilities have two-, three-, or four-digit DSHOSPIDs.

Beginning with the 2011 data, hospital identifiers on the Central Distributor SID, SASD, and SEDD are only available to data purchasers whose primary affiliation is with a college, university, or government agency and whose intended use of the data does not involve product development, market research, or commercial applications. This distinction is made when you purchase the Central Distributor files.



Kentucky

Beginning October 1, 2017, acute physical rehabilitation cases discharged from Distinct Part Units of acute care hospitals have been separated from other discharges and reported under different DSHOSPID's. These DSHOSPID's take the form of DPRnnn, where nnn represents 3-digit numbers.



Maine

Maine provided facility identifiers developed by the Maine Health Data Organization.



Maryland

Maryland supplied the Medicare Provider Number as the unique hospital identifier.

In 2000, some values of DSHOSPID have leading blanks. These DSHOSPIDs need to be left justified to be consistent with discharges from the same DSHOSPID in 2000 and other years.



Maryland

CPT1 for one hospital is 100% missing in 2009.



Massachusetts

In data year 2004, Massachusetts changed the format of the state-specific hospital identification numbers stored in DSHOSPID. For the 2004 HCUP data files, the new hospital identifiers were mapped back to the previous coding scheme. Beginning with 2005 data, the new hospital identifiers are retained.



Minnesota

Minnesota assigned hospital identifers specifically for the HCUP data collection process.



Nebraska

Nebraska assigned hospital identifiers based on peer groups developed by DATABANK.



New Jersey

The New Jersey hospital provider identification numbers are preceded with "S" to indicate psychiatric units and "T" for rehabilitation units within the hospital.



New York

Beginning in 2008, New York suppressed the identifier for the hospital (DSHOSPID) on records with an indication of induced abortion. These records are retained in the HCUP files with the DSHOSPID set to "BLNK". New York identifies an indication of induced abortion by ICD-9-CM diagnosis or procedure code:

  • An admitting, principal, or secondary diagnosis of "6350" through "6399", or "7796".
  • A principal or secondary procedure of "690", "695", "696", "6993", "738", "7491", "750", or "9649".


North Carolina

North Carolina provided facility identifiers developed by the data processing contractor.
