P1223PATIENT REMOTE MONITORING IN AUTOMATED PERITONEAL DIALYSIS: 2017-2019 CLINICAL EXPERIENCE IN A SINGLE CENTER

Abstract

Abstract Background and Aims We conducted an observational study in a group of patients in automated peritoneal dialysis (APD) to evaluate the impact of the introduction and the long-term use of a telemedicine system for remote patient monitoring (RPM, Claria Sharesource Baxter). Method From April 1 2017 to December 31 2019 (33 months) we followed 42 APD patients with RPM, sex F 20 M 22, age 70±14 years, on PD treatment for median 10 (IQR 3-23) months, distance from the center 18±14 km in mountain and hill area. Have been studied 505 months of RPM overall, per patient median 9 (IQR 3-19) months, corresponding to 11685 APD sessions overall, per patient median 206 (IQR 52-457) sessions. Results Have been registered 1125 alarms (red flags) overall, per patient median 9 (IQR 1-45) alarms, rate 2.2 alarms patient-month (0.1 alarms per session). Analyzing the causes of the alarms: “dwell time lost” (>45 min) 1006 (89%), “drain anticipation” (>2 times) 22 (2%), “fill or dwell bypass” (>3 times) 15 (1%), “various causes” (>10 times) 86 (8%). “Various causes” alarm group sums mainly slow drain for set kinking and insufficient drain volume. We count 195 remote modifications of dialysis program overall, median per patient 3 (IQR 1-7), rate 0.02 patient month with a ratio 0.2 modifications per alarm. Looking to program modification, the alarm type specifically linked to modifications has been insufficient drain volume of the “various causes” group (36 events, 18% of all modifications). We found a positive correlation between the number of treatments and alarms (r=0.534, p<0.001). In the observation period the overall hospitalization days were 403, rate 0.8 days patient month, ratio 0.02 hospitalization days per APD RPM session and ratio 0.4 hospitalization days per alarm. Conclusion The study shows that APD with RPM improves patients’ follow-up changing the organization of the center. In the long term the telemedicine system shows the advantages of a careful and daily monitoring. The rates of alarm, change of prescription and hospitalization resulted very low in our experience.
