title: [The organization of the database and data flow in mass screening for cervical cancer].
abstract: Mass screening, because of very many potential patients, requires storing and processing a great deal of medical and population information. That is why it should be supported not only by human resources but by computer techniques as well. The example of a computer science application in medicine is Populations Database System (PDB) which was designed and implemented in the Department of Institute of Mother and Child in Białystok. The aim of this work is to evaluate PDB System's effectiveness in mass screening for cervical cancer. Population database contains several standard database files (DBF) and indexes. All the data is organized as a relational database. Every data relationship is at least in 1NF (first normal form). Functional dependency holds for the structures of database. Because of great variety of stored data it was essential to design how to enter information and how to combine database files to avoid redundancy. It has particular importance for the special functions of system, for example printing and sending individual invitation for an examination. In addition the system can realize all standard database functions and some statistical analysis. Special attention was paid to the problem of data security which is particularly important for medical information. Thanks to PDB system we could realize mass and active screening for cervical cancer in Białystok. Without computer techniques it would be impossible to store, process and interpret so much data.
