Editor's Notes
- La mitad de la poblacion mundial sufrirá asma o diabetes para el 2050
- Patients are referred to the Home Hospitalisation Unit (HHU) from any care division in the health region, for both primary and specialised care, by means of a request to the medical doctor HH improves hospital discharge and shorts hospital stay, benefits patient and family living conditions, comfort and rapid return to normal activity, reduces the final cost of procedures and guaranties the same quality attendance and performed by the same professional staff as in conventional hospitalization
- Consequently, the designed architecture is composed by different elements that must cover the whole spectrum of functionalities depending on the location of the system users: HHU Database: It stores all the HHU information. HIS (Hospital Information System): It is a legacy system where all the hospital data is held. Orconera interacts with it in order to obtain the already existent information of the patients. OrconeraPC: This is the core application and it is able to perform all the management tasks that cover the user requirements defined in the analysis phase. Located in the hospital PCs, it accesses directly to the HHU Database. ORCONERA is deployed through Java Web Start in order to easily update to new versions of the application and avoid the need of installing the application in each PC,. OrconeraTabletPC: This application is meant to support the nurses and doctors that visit the patients at home. OrconeraTabletPC can perform many management tasks but not as much as OrconeraPC. The necessary information about the patients is received using a web service and then stored in an internal database. The modified or added information will be later synchronized with the HHU Database through another web service when connectivity is available. OrconeraPDA: This application allows the patient to interact with the system and self-monitorise, with access to limited information. The access to the system is through web services in the same way that OrconeraTabletPC, Server: The server hosts the OrconeraPC application (Java Web Start Server) and the Web Services used by OrconeraTabletPC and OrconeraPDA.
- The system has been developed in Java 5.0 (J2SE), by using Hibernate as data persistence technology and XML to exchange data between the database and the Web Server. In addition, a Tomcat application server is used as Web Services and Application container. Finally, the extra-hospital environment lacks of wired connectivity, which implies the use of wireless technologies as UMTS, GPRS and Bluetooth in the system to perform the communication. Regarding the devices employed, Orconera takes use of PC hosts at the Hospital and Tablet PC as mobile devices to work at the Extra-Hospital environment. A PCMCIA 3G Card is used to connect the mobile devices with the Tomcat server through a VPN. Additionally, Vital Signal Monitors are used for tracking the patient vital constants. The system guarantees compliance with all the laws relating to the data protection: Organic Law on Protection of Data (LOPD), Organic Law on Regulation of Automatic Data Processing (LORTAD) and Law on Information Society Services and Electronic Commerce (LSSICE). Since the privacy level of all the data is maximum at all times, a record must always be kept of who accesses, at what time, from which place, to which data and what is done to these data.
- Time Same work with less amount of time QoS Better patient attention Security Every activity is registered in logs Costs Great cost cutting that can be reverted in new hospital investments Resources Improvement professionals working conditions
