AHCPR Announces Latest Release of Inpatient Data
Media Advisory Date: January 29, 1997
The Agency for Health Care Policy and Research today announced
the availability of
its Nationwide Inpatient Sample (NIS) Release 3, containing 1994
data on hospital
inpatient care, conditions, services and costs.
Developed as part of AHCPR's Healthcare Cost and Utilization
Project (HCUP-3), the
NIS consists of 6.4 million patient records from a geographically
dispersed sample of
904 community hospitals in 17 states. NIS Release 3—together
with NIS Releases 1
and 2—form the largest, most powerful source of
discharge-level information for
hospital inpatients, regardless of payer, in the United States.
NIS Release 3, which
consists of six CD-ROMs designed to run on desktop computers,
on more than 100 variables, including:
- Patient demographic characteristics.
- Total patient charges.
- Median income for patient's area of residence.
- Diagnoses and procedures.
- Admission and discharge status.
- Links to hospital and community characteristics.
- Length of stay.
- Weights for national estimates.
- Expected pay source.
As with past releases, the data will prove useful to both public-
organizations interested in hospital care. Data from previous
releases have been used
to compare services of various types of payers; to assess
treatment variations; to
prioritize strategies for product development by studying
conditions treated in hospitals;
and to determine the costs of treating specific conditions. More
than 200 organizations
are now using NIS data.
In addition, the hospital identifiers in NIS Release 3 allow
users to obtain detailed
information on individual hospitals by linking the data with the
Association's Survey of Hospitals. Users can also obtain
county-level information, such
as the availability of medical personnel and services, by linking
the NIS data to the
Bureau of Health Professions' Area Resource File. The weights
included in the NIS
data allow users to produce national estimates.
The HCUP-3 Nationwide Inpatient Sample Release 3 is available
from the National
Technical Information Service (NTIS publication number PB
97-500433), 5285 Port
Royal Road, Springfield, Va. 22161; telephone (703) 605-6000 or 800-553-6847. The
set of six CD-ROMs comes

assist SAS and SPSS
users). NIS Release 1, which presents data for 1988-92, is

cost of $300. NIS Release 2, covering 1993, is available on six
