National Hospital Discharge Survey Series

Scope of Study

Summary:

The 2006 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).

Subject Terms:

health care facilities, hospitalization, hospitals, illness, medical care, medical evaluation, medical procedures, medical records, patients

Geographic Coverage:

United States

Time Period:
  • 2006

Date of Collection:
  • 2006

Universe:

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

Data Types:

administrative records data, survey data

Data Collection Notes:

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

Methodology

Sample:

In 2006, the sample consisted of 501 hospitals. Of the 501 hospitals, 23 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 478 in-scope (eligible) hospitals, 438 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.

Data Source:

hospital records

Extent of Processing:

All archived data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. The archive 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, the archive performed the following processing steps for this data collection:

  • Performed consistency checks.
  • Standardized missing values.

Access and Availability

Note:

Detailed file-level information (such as record length, case count, and variable count) is listed in the file manifest.

Restrictions:

In preparing the data file for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution NCHS requires, under Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions.
