Sensor-based Congestion ALert for Events in Peritoneal Dialysis (SCALE-PD)

The objective of this study is to explore the utility of hemodynamic biomarkers measured by the Bodyport Cardiac Scale in predicting worsening events attributable to fluid overload among those with kidney disease on peritoneal dialysis. The study will explore individual biomarkers, as well as composite biomarker indices, such as the Congestion Index and a novel PD Index.

• Bodyport Cardiac Scale (Device): The Bodyport Cardiac Scale captures several physiological signals, which are used to derive multiple biomarkers that reflect a user's hemodynamic and fluid status.

Primary outcomes

• Sensitivity Analysis [1 year]: Sensitivity for predicting usable PDE > 0.40 and an alert rate of < 4.3 alerts per patient-year.

Secondary outcomes

• Peritoneal Dialysis (PD) Events [1 year]: Collection of approximately 40 usable PD Events for model development and validation. These events are defined as urgent, unscheduled clinic visits or emergency department visits or hospital admissions for worsening fluid overload and initiation or intensification of treatment for fluid overload or termination of treatment due to fluid related cause.
