DiscussionInformation Systems have very rarely been justified in the literature. It appears that the only justification for their use is that they can duplicated the existing procedures "like the physician thinks" and the "Really Big One"...cut down on adverse reactions and medication errors by providing medication checking. Actually, if the healthcare worker was doing what he or she was suppose to be doing, there would be even fewer errors...not thinking and relying on the computer to catch all the healthcare worker's mistakes may be asking for trouble. IntroductionDefinitionHealth Informatics involves the study of how information science, computer science, and related technology can support health information systems, health care management, health research and health care education. Computers in Healthcare, in large part, have not been worth the investment made in their purchase and use. The reason for this is that most computers and computer applications that have been developed are those that replaces a manual system. No new uses or "information" is derived from there use. These manual replacement systems are generally single functional and very rarely integrates with other data systems. In summary, these manual replacement systems are expensive to implement and provide very little information that was not known before there implementation. Information Systems are just that...they provide New and usefully information. While they may be expensive, their cost is cheap compared to the information that is obtained to manage and to improve benefits and reduce costs. If a "computer system" does not provide new useful information, then it is not an information system. Information Systems collect massively amounts of data and relates variables across dimensions and time. A computer system will make it easy to "made appointments" but an Information System will give help you analyze (1) how the appointment was made by the client (2) time of day that the client made the appointment (3) length of time that it took (4) errors that were encountered, (5) services requested (6) time of day that these services were requested ...all needed in order to increase efficiency and give better service to the client. Information Systems are used by managers, computer systems are used by clerks. In general, Systems have been a hard sell to the "Ministry of Health." This is because vendors are trying to sell "computer systems"...and not "Information Systems". Computer systems are hard to justify...Information Systems are easy....there is a very real difference between the two. Globalization of InformationAs data communication and the Internet become more accessible, developing countries will no longer by isolated from the rest of the world. The international community has been using the Internet for years to confer with colleagues by e-mail and in some cases to send data files. Very few nations today lack an outside connection. Even in Bangladesh, in only a few years, the number of Internet providers (IP) went from one to over a dozen and the Internet has become a major implement in the education of the people.. Web technology is the universal document format. Web pages created on one machine can be view from any other machines. It is technologically possible to access not only e-mail but also any type of data that may be stored on a computer. With this capacity, health care data from any site may be forwarded to any other site with complete transparency Although much of the work in communication technology has been directed towards the “electronic patient record” (EPR) and the accessibility of library type material, what is new today, and potentially more valuable, is the ability of making use of the Internet for decision-support and research. Lauren Eder is her book Managing Healthcare Information Systems with Web-Enabled Technologies defines Web-Enabled Technologies as
In this paper, we will discuss the advances and the problems that such systems present. We will discuss the ways that this technology can be used by developing countries and we will present a simple proposal for the implementation of such a system. The opinion of many has been to avoid the installation of advance technology and information systems in developing countries. InHCc does not share that belief. Goal of Health Information SystemsThe goal of Health Information Systems is to provide the measurement of the following key dimensions of health systems performance are:
