Introduction

This article describes a distributed e-healthcare system that uses the service-oriented architecture as a means of designing, implementing,and managing healthcare services

4

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.

The Development of Healthcare Standards

HL7 DICOM National Council for Prescription Drug Programs, Current Procedural Terminology, International Classification of Diseases, Logical Observation Identifiers, Names, and Codes, National Drug Codes, and Systematized Nomenclature

of Medicine.

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 .

Distributed E-healthcare System

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.

Patient interfaces

The Web server interface to the clinic module lets a patient request an appointment with a physician for a specific date and time using the clinic Web server.

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 drug-delivery devices that prompt and monitor the regular and timely consumption of medications.
