*The selling price of the GPRS unit was €480, depreciation of €48 per year; we used 5 units for 25 patients to be initiated in 2 years=€480, that is, in total=€19.20/patient. Running of the GPRS unit was included in this price.
†The Dyna-vision selling price is ~€1000, depreciation of €100 per year; we used 2 devices for 2 years to initiate 25 patients=€400=€16 euro per patient. The Dyna-vision requires a service for the online platform which costs €62/months=€62*25 months=€1550 in total=€62/patient.
‡The transcutaneous monitor selling price is ~€10 868, depreciation of €2604 per year. As these devices are used very frequently in regular care, we estimated that depreciation per night use was €11 (estimated use: 240 nights per year). Additionally, costs for material (sensor/membrane, etc) were estimated at €25, resulting in €36 per measurement.
§Only one patient still had a paid job and therefore, these costs were not taken into account.
