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 contains data for the years of 1979 through 2000 for both newborn infants (Part 1) and non-newborns (Part 2). The medical information is coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH REVISION, CLINICAL MODIFICATION (ICD-9-CM). 1979 2000 2002 United States Patient discharges from nonfederal short-stay hospitals located in the 50 states and the District of Columbia. administrative records data The redesigned (as of 1988) NHDS sample includes with certainty all hospitals with 1,000 or more beds or 40,000 or more discharges annually. The remaining sample of hospitals is based on a stratified three-stage design. The first stage consists of selection of 112 primary sampling units (PSUs) that comprise a probability subsample of PSUs used in the 1985-1994 National Health Interview Surveys. The second stage consists of selection of noncertainty hospitals from the sample PSUs. At the third stage, a sample of discharges was selected by a systematic random sampling technique. For 2003, the sample consisted of 501 hospitals. Of these, 22 were found to be ineligible. Of the 479 eligible hospitals, 426 hospitals responded to the survey. hospital records Both files contain weight variables (wgt). Users should refer to the user guide for further information regarding the weight and their derivation. Additionally, users will need to weight the data prior to analysis.

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. Per agreement with NCHS, ICPSR distributes the data files and technical documentation in this collection in their original form as prepared by NCHS. Ann Arbor, Mi.: Inter-university Consortium for Political and Social Research Additional special permissions, where applicable, are described in the restrictions field. 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.

In addition, the National Center for Health Statistics stipulates the following terms:

The Public Health Service Act (42 U.S.C. 242m(d)) provides that the data collected by the National Center for Health Statistics (NCHS) may be used only for the purpose for which they were obtained; any effort to determine the identity of any reported cases, or to use the information for any purpose other than for health statistical reporting and analysis, would violate this statutory restriction and the conditions of the data use agreement. NCHS does all it can to ensure that the identity of data subjects cannot be disclosed; as well as characteristics that might lead to identifications are omitted from the data set. Nevertheless, it may be possible in a rare instance, through complex analysis, and with outside information, to ascertain from the data sets the identity of particular persons or establishments.

Considerable harm could ensue if this were done.

By clicking on the "I Accept" button below, you agree to the following conditions:

I will not use nor permit others to use the data in these sets in anyway except for statistical reporting and analysis;

I will not attempt to link nor permit others to link the data set with individually identifiable records from any other NCHS or non-NCHS data set;

I will not attempt to use the data sets to learn the identity of any person or establishment included in any set; and

If the identity of any person or establishment should be discovered inadvertently, then

no use will be made of this knowledge,

the Director of NCHS will be advised of the incident,

the information that would identify an individual or establishment will be safeguarded or destroyed as requested by NCHS, and

no one else will be informed of the discovered identity.
