MOMEDA is a two-years project supported by the European Commission (Telematics Applications Programme of DGXIII - Health Care Sector). The main objectives of the project are the development of a compact personal information terminal for hospital and home care environments that could be used by patients and a demonstrator that allows the consulting physician to access electronic patient record data from outside the hospital, using a hand held companion device connected to GSM network. Special attention is paid to a Personalized Medical Information System (PMIS) which will allow patients to access customized disease-specific information material that will enable them to fully understand in a simple and constructive form what their medical problem is, what the planned procedures are, what lifestyle they should follow during and after their hospitalization, thus becoming more qualified partners in the recovery process. Considering the fact that in most cases informed and educated patients are usually satisfied patients when the treatment is finished, patient satisfaction can be also accomplished. The design considerations for the PMIS system are presented and the implementation is discussed.
