In this paper we describe ARES 118, the prehospital Emergency Medical Service of the Region Lazio, Italy, focusing on its data system used to populate a data warehouse and to create ad hoc reports. ARES 118 is a regional public mono-specialized health company, established in 2004, that manages the emergency care throughout the Region Lazio. Methods. Being a peculiar company in its kind, and being the first experience of this kind in Italy, ARES 118 has begun to equip itself, in an autonomous way, with a corporate information system, starting from what already existed as data collection from the individual provincial operating Centers and then by activating a unique information system at a regional and company level by deploying a data warehouse. All operations were carried out using open source software. Results. Currently, ARES 118 is equipped with a business information system that enables data collection with its storage, management and processing of the same in fairly and easy way. The system allows the pro- duction of specific reports and measures modulated on the user requests in order to highlight the different aspects of the activity. Conclusions. The production of ad hoc reports, with the possibility of developing specific indicators, allows the identification and analysis of critical areas/processes in order to implement any corrective actions and monitor the effectiveness of the same.
