Diuretic Tuner Clinical Decision Support Mobile Device Application for Diuretic Titration in Hypervolemic States

Description

This purpose of this study is to determine the effectiveness of a mobile phone application in helping to control body swelling in patients with kidney problems. The application will help in the day to day adjustments in diuretic medication dosing. Participants in this study will have an application loaded on to their mobile phone by the study team and be taught how to use it over a 2 hour visit. Participants will need to check their blood pressure and weight daily and enter this information into the mobile phone application every day. Participants will need to follow daily instructions in their medication dosing provided by the application. There will be periodic blood testing. This will happen at 2 weeks, 90 days, and up to 4 other times if necessary. At the end of the study there is a 2 hour study visit during which participants will answer a survey. The total length of the study is 90 days.Study Population: 30 subjects with signs of hypervolemia and either nephrotic syndrome or chr
