Computer technology has impacted the practice of medicine in dramatic
ways. Imaging techniques provide non-evasive tools which alter the
diagnostic pro- cess. Sophisticated monitoring equipment presents new
levels of detail for both patient management and research. In most of
these high technology applica- tions, the computer 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, loca-
tion 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. Moreover, 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.
