Water removal during automated peritoneal dialysis assessed by remote patient monitoring and modelling of peritoneal tissue hydration.

ABSTRACT: Water removal which is a key treatment goal of automated peritoneal dialysis (APD) can be assessed cycle-by-cycle using remote patient monitoring (RPM). We analysed ultrafiltration patterns during night APD following a dry day (APD_DD; no daytime fluid exchange) or wet day (APD_WD; daytime exchange). Ultrafiltration for each APD exchange were recorded for 16 days using RPM in 14 patients. The distributed model of fluid and solute transport was applied to simulate APD and to explore the impact of changes in peritoneal tissue hydration on ultrafiltration. We found lower ultrafiltration (mL, median [first quartile, third quartile]) during first and second vs. consecutive exchanges in APD_DD (-61 [-148, 27], 170 [78, 228] vs. 213 [126, 275] mL; p < 0.001), but not
