National Hospital Discharge Survey, 1979-2006: Multi-Year Public Use File (ICPSR 24281) RSS

Principal Investigator(s):

Summary:

The 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 bed size, ownership, and region of the country is also included. This collection includes data for non-newborns for 1979-1989 (Dataset 1), non-newborns for 1990-2006 (Dataset 2) and newborns for 1979-2006 (Dataset 3). The medical information is coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH REVISION, CLINICAL MODIFICATION (ICD-9-CM). In addition, there are several Excel files that contain information needed to calculate relative standard errors (RSEs) and to compute utilization rates based on Census population estimates (POPs).

Geographic Coverage:   United States

Time Period:  

  • 1979--2006

Date of Collection:  

  • 2008

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

Data Collection Notes:

Per agreement with NCHS, ICPSR distributes the data files and technical documentation in this collection in their original form as prepared by NCHS.

Methodology

Sample:   Detailed information regarding sampling can be found in the documentation.

Weight:   Because the NHDS is a sample survey, the application of weights to the sample data is necessary in order to produce national estimates of inpatient hospital utilization.

Data Source:

hospital records

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 variable labels and/or value labels.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.
