Summary:

The 2005 National Hospital Discharge Survey (NHDS) collects medical and demographic information annually from a sample of hospital discharge records. Variables include patients' demographic characteristics (sex, age, race, marital status), dates of admission and discharge, source and type of admission, status at discharge, final diagnoses, surgical and nonsurgical procedures, dates of surgeries, and sources of payment. Information on hospital characteristics such as bedsize, ownership, and region of the country is also included. The medical information is coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH REVISION, CLINICAL MODIFICATION (ICD-9-CM).

Geographic Coverage:   United States

Time Period:  

  • 2005

Date of Collection:  

  • 2005

Universe:   Patient discharges from nonfederal short-stay hospitals located in the 50 states and the District of Columbia.

Data Types:   administrative records data

Data Collection Notes:

Detailed information regarding ICD-9 codes can be found in the documentation.

Methodology

Sample:   In 2005, the sample consisted of 501 hospitals. Of the 501 hospitals, 28 were found to be out-of-scope (ineligible) because they went out of business or otherwise failed to meet the criteria for the NHDS universe. Of the 473 in-scope (eligible) hospitals, 444 hospitals responded to the survey.

Weight:   These data contain one weight variable, weight. Users should refer to the technical documentation for further information regarding the weight and its derivation. Additionally, users may need to weigh the data prior to analysis.

Extent of Processing:  ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Created online analysis version with question text.
