Development and evaluation of regional health database systems.

We have developed information systems for regional public health in some areas. These systems have the following functions: (1) to register results of examinations, life style, follow-up data, diseases, (2) to output some reports and statistics for daily jobs, (3) to make a personal health database, (4) to display stored data by character, trend graph, radar chart or bar chart, (5) to analyze regional health problems, (6) to extract dada about persons with some conditions, (7) to compare data among some examinations, (8) to analyze risk factors. Each database can be transferred to mini-notebook type personal computers. So, they can be used anywhere and any time. Some access controls are performed for security. The systems are used in routine works, health consultation for persons and health education for groups. We have evaluated the systems and got some useful results. Using the systems, daily jobs can be performed with good accuracy and less labor, each subject can understand one's health status easily and clearly, grasps of health problems can be made quantitatively and health projects can be planned by scientific methods.
