National information system on hospital treatment.
National information system on hospital treatment (HOSTREAT) supports health management system applied by the Ministry of Health and its professional services at the Public Health Institute of Slovenia. The main project objective was data quality, having in mind advanced analytical methods such as knowledge discovery in databases. The step was a huge one, as the related national statistics rests on every single hospital event, called an episode. By the project definition, an episode covers therapeutic treatment of one sick or injured person in one hospital within one health service specialty. So, many problems arose within the three years of project phases. Much research work was to be done on programming tools and the information system itself. This paper deals with five strategic problems and corresponding corrective actions.
