the physician's diagnosis, and the kinds of diagnostic and therapeutic
services rendered. Information is included on the physician's
specialization and geographic location. Demographic information on
patients, such as age, sex, race, and ethnicity, was also collected.

Restrictions: |
In preparing the data tape(s) 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.
