Fluid Intake Management in Maintenance Hemodialysis Using a Smartphone-Based Application: A Pilot Study

Rationale & Objective: Increased interdialytic weight gain (IDWG) has been associated with increased morbidity and mortality. We evaluated the usefulness and safety of a mobile application (app) that allows patients receiving maintenance hemodialysis to self-monitor their daily fluid intake. Study Design: Within group comparison before or during intervention. Setting & Participants: Patients receiving maintenance hemodialysis with mean IDWG of 20% while using the app. Information gleaned from structured patient interviews will be used to refine this app.
