[Applications of computer database in prospective studies on the mortality of patients with diagnosis of schizophrenia].

The efficacy of epistemological research including the analysis of mortality rates depends to some extent on the ability to make use of registration systems and the processing of data. In the paper presented below the author outlines the application of a programme-dBase III plus, created for computer data bases and its use in the assessment of a prospective study of mortality of patients with a schizophrenic diagnosis. Three data bases (S295.DBF, SB295.DBF, GUS1982.DBF) of varying sizes were created, each of which possessed specific categories of information.
