Paper Abstract

The goal of the current study is to describe the experience of the Heart Institute (InCor) in the implementation of a patient-oriented Hospital Information System (HIS) integrated with the Radiology Information System (RIS) and the Picture Archiving and Communication System (PACS) in an open-source three-tier architecture. The system was designed in modules that permits patient admission, discharge and transfer (ADT), registration of medical activities, registration of diagnoses and therapy, order entry and access of all patient data, including vital signals, images and lab tests. The modules are integrated in a single Web-based application allowing easy and fast navigation through the application. In order to provide high quality of patient care in an efficient and cost-effective manner, thin clients workstations in a Linux environment were used. To access the patient information users have to perform an authentication procedure that uses LDAP protocol, which also defines a profile to the users. The system is fully integrated to the InCor's PACS, allowing instant access to the image database from applications that requires this information, such as diagnostic reports. For displaying the images a Java DICOM viewer was implemented. On the server side, a Java DICOM server was designed to allow communication with all DICOM modalities.
