1 Τμήμα Τεχνολογίας Ιατρικών Οργάνων Εργαστήριο Βιοϊατρικής Τεχνολογίας Dagstuhl Seminar on Assisted Living Session IV: Hardware Challenges Position Statement: Adapting Biomedical Technology to support Home-Care Dr. rer. nat. Basile Spyropoulos Medical Instrumentation Technology Department, Faculty of Engineering, Technological Education Institute of Athens, Athens, Greece

2 Τμήμα Τεχνολογίας Ιατρικών Οργάνων Εργαστήριο Βιοϊατρικής Τεχνολογίας November 14-17, 2007Dagstuhl Seminar on Assisted Living2 Contemporary diagnostic procedures  Contemporary diagnostic procedures entail the use of Biomedical Technology, and consist of the collection of diagnostic information, and the evaluation and assessment of the individual patient.  The aspect of the collection of diagnostic information comprises of:  Clinical information obtained by the case history and by inspection, palpation, percussion, auscultation etc.  Signals related to bodily functions which are collected from in vivo diagnostic procedures (ECG, EEG, EMG etc).  Data acquired through in vitro diagnostic tests.  Images related to the morphology and the functions obtained from medical imaging procedures.  Information related to various past therapeutic interventions.  Data which are of administrative and of financial importance such as insurance, costs of medical treatment, cost of hospitalization etc.

11 Τμήμα Τεχνολογίας Ιατρικών Οργάνων Εργαστήριο Βιοϊατρικής Τεχνολογίας November 14-17, 2007Dagstuhl Seminar on Assisted Living11 Concluding remarks  Home-Care gains access to contemporary multifarious technologies that provide for limited, however, reliable and adequate medical data, compared to the ones they could virtually be acquired in the Hospital.  The additional information concerning the patient’s living environment, combined with the diagnostic feeling, based on the General Practitioner’s length of practice, and on the uniformity and regularity of the phenomena he has encountered, lead usually to a successful diagnosis and treatment.  Our own research and development experience, the published reports of similar attempts, and finally, the evaluation of commercially available products, argue for the gradual build-up of continuously improved home- care hardware.  This fact will allow for, both, the life saving urgent intervention, and the successful supervision of a long term condition, thus, prolonging the length and improving the quality of the life of elderly and frail patients, at home.
