#2519 Technical complications assessment of the novel SILENCIA© APD cycler

Abstract

Abstract Background and Aims A new gravimetric peritoneal dialysis (PD) cycler, SILENCIA (Fresenius Medical Care, Bad Homburg, Germany), has been reported to achieve not only an adequate dialysis dose, but it is proposed also to be easy to use, cost-effective, and silent. In this study, we explored the alarms, cautions and number of terminated treatments due to potential errors and malfunctions of this new cycler. Method Over a period of 6 months, technical related device data was collected remotely, via a cloud-based infrastructure, including a Gateway and a Card Reader. The technical related data was then analyzed and visualized in a Dashboard. In special occasions, e.g., in case of device issues additional further technical data was collected on-site at patients’ home by a Service Technician. Results In total, 1860 technical related device data sets were collected in 3 different countries (Chile, Ecuador, and Turkey) from the treatments of 18 PD patients. 15 out of 32 patients were between 31 and 50 years old, and the mean PD duration was 2.14 years (n = 32). In total 9 alarms (5 per 1000 treatments) occurred, 5 being related to software bugs, 4 undetermined. 99.5% of the treatments were performed without alarms. In average, 5.3 cautions per 1000 treatments were observed, 94.7% due to blocked tubing system. Power failures only occurred in 4% of the treatments, with an average duration of 38.6 minutes. During power failures, the device does not wake up patients, proceeds as the power is back and treatment stays within schedule due to FlexPoint. A detailed list of alarms, cautions and power failures is presented in Table 1. Conclusion The results of this study demonstrate that SILENCIA supports PD treatment with a low number of alarms and cautions, which may help to achieve a smooth therapy for the patients, especially considering that the treatments are mainly performed during the night.
