I NFORMATION technology has expanded to encompass
nearly every industry in the world from finance and

focuses on using the Internet as the backbone to connect sup-
pliers, enterprise systems, physicians, and patients to one value

Fig. 1 depicts that health care organizations can use the In-

between all entities in the supply chain. In addition to general
communication and data exchange through the Internet, sup-
pliers, including insurance providers and pharmaceutical com-
panies, can access part of a health care organization’s enterprise
systems via secure extranets. The model also shows that internal
company data can be accessed by physicians and specialists via
intranets. Notice also that the Internet is not shown to be a re-
