ome hemodialysis (HD) for the treatment of end-stage renal disease was first implemented about 30 years ago. In this paper the application of telematics monitoring services for supporting patients who need home HD or satellite HD is described. Two modified HD machines were located in two renal units, and a central control station (CCS, UNIX workstation with multimedia PC terminal) was located in another room of the hospital. Bidirectional communication between the modified HD machines and the CCS was managed using ISDN (Integrated Services Digital Network) links. Nine patients had 150 HD sessions performed using these HD machines over a period of 5 months. This system, called the HOMER-D system, provided on-line, remote supervision of the HD machine-related functions and the clinical condition of the patients through measurement of blood pressure, pulse rate, PO 2 (pulse oxymetry), and ECG from the CCS. Any disturbances in the functioning of the HD machines were both visible and audible in the CCS, and the observer could give teleconsultation to the renal unit staff. No major dialysisassociated complications were observed; all data and alarms were transmitted correctly; and patients received adequate HD treatment. |
