Government Hospitals in Nigeria.

Patient information system has been discovered to be the key contributor to success in the prescription of drugs for major ailments like diabetes and others. This research has discovered difficulties that the medical experts are facing in the aspect of patient information system. The solutions to those difficulties have been considered in the design and development of this automated prescription and patient information system. This work applied the technology of artificial intelligence in combination with the technology of distributed database system for the development of hybrid automated system. The hybrid automated system has been specially designed to be used by Federal Government hospitals in Nigeria. The software is of great importance to medical professionals like doctors, and nurses. In situations where a medical expert is not available, some other medical professionals like young doctors and nurses could consult the computerized expert system for diagnosis and prescription of drugs based on patient information system. The Ministry of Health can easily install this software at the Federal Government hospitals in support of available human resources. The automated system is to assist in management of the database of the patients ’ particularly diabetic ones [6], [7]. This research applied distributed database system for patient information system. It shows how the query is distributed to the various Informix database servers by a coordinating Informix database server, and how the coordinator reassembles, transforms, and aggregates the intermediate results from the various participating database servers for prescription and patient information system
