Computer technology has impacted the practice of medicine in dramatic
ways. Imaging techniques provide noninvasive tools which alter the
diagnostic process. Sophisticated monitoring equipment presents new
levels of detail for both patient management and research. In most of
these technology applications, the com- puter is embedded in the device;
its presence is transparent to the user. There is also a growing number
of applications in which the health care provider directly interacts
with a computer. In many cases, these applications are limited to
administrative functions, e.g., office practice management, location of
hospital patients, appointments, and scheduling. Nevertheless, there
also are instances of patient care functions such as results reporting,
decision support, surveillance, and reminders. This series, Computers
and Medicine, will focus upon the direct use of infor- mation systems as
it relates to the medical community. After twenty-five years of
experimentation and experience, there are many tested applications which
can be implemented economically using the current generation of
computers. More- over, the falling cost of computers suggests that there
will be even more extensive use in the near future. Yet there is a gap
between current practice and the state-of- the-art.
