Introduction
This article describes a distributed ehealthcare system that uses the serviceoriented architecture as a means of designing,
implementing,and
managing
healthcare
services

The Quality of Healthcare in
the US


A Washington Post article indicates that as
much as 5 percent of the three billion
prescriptions filled each year are incorrect.
US National Association of Boards of
Pharmacy reports that as many as 7,000
deaths occur in the US each year because of
incorrect prescriptions.

SOA
(Service-oriented Architecture)


SOA, along with Web services and Atom and
RSS feeds, provides the opportunity for
diverse systems to interoperate without
requiring the use of a particular kind of
computer system.
SOA use open standards, such as XML and
SOAP .

This system uses SOA.
The clinic,pharmacy, and patient modules
provide the actual services for the distributed
e-healthcare system.
we designed the prototype with security and
privacy.
This system only privileged users can view or
modify the data.

Conclusion


A distributed e-healthcare system can solve
that exists only within the physician’s office.
The e-healthcare system described here can
be readily extended to other healthcare
professionals.
This system can be interfaced to drugdelivery devices that prompt and monitor the
regular
and
timely
consumption
of
medications.
