About this Collection

In 1964, the National Center for Health Statistics initiated a continuous sample of hospital discharge records, collecting medical and demographic information for calculating statistics on hospital utilization, and on the nature and treatment of illness among the hospitalized population. In the surveys, which are made available in annual public use files, data are abstracted from medical records for a sample of patients discharged from a sample of nonfederal short-stay hospitals across the nation.

National Hospital Discharge Survey, 2008

The 2008 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), date of 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. The medical information is coded using the INTERNATIONAL CLASSIFICATION OF DISEASES, 9TH REVISION, CLINICAL MODIFICATION (ICD-9-CM).

National Hospital Discharge Survey, 1979-2006: Multi-Year Public Use File

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).
