Overview
Brief Summary
Methods are needed to help decrease interdialytic weight gains in hemodialysis patients. One potential method for accomplishing this goal is to develop an app for smartphones that allow patients to track their fluid intake throughout the course of the day. This protocol is designed to test the safety and efficacy of this app, followed by use of the app in patients with large fluid weight gains between HD sessions. In the Vanguard phase, patients without large interdialytic fluid gains (less than 4%) will use the app to to determine the association between the interdialytic weight gain and the fluid consumed as recorded by use of the app for each interdialytic period. The app will be modified, if needed, prior to initiation of the full scale trial.
Detailed Description
For the Vanguard phase of the trial, a survey will be used to assess the usability of the app as well as to collect recommendations for changes to the app itself (appendix one). For this Vanguard phase study, the survey for participants will be designed to assess the usability of the app (ease of use in general, ease of capturing fluid intake data, including the choice of preselected volumes for fluid containers, reasons for not using the app more frequently, the usefulness of the app notifications, ease of sending data to the study coordinator for review). The survey for the study coordinator will be designed to assess the ease of reviewing data from participants and the perceived difficulty of patient use of the app.

Outcomes
Primary Outcomes
Amount of fluid consumed
Time Frame: 1 month
The fluid consumed as recorded by use of the app for each interdialytic period. The association between the interdialytic weight gain and the fluid consumed will be assessed by a repeated measures analysis of variance with an unstructured covariance matrix.
Amount of interdialytic weight gain
Time Frame: 1 month
The amount of weight gain as recorded by use of the app for each interdialytic period. The association between the interdialytic weight gain and the fluid consumed will be assessed by a repeated measures analysis of variance with an unstructured covariance matrix.
Secondary Outcomes
- Number of patients who experienced a 50% increase in fluid intake during app use(1 month)
- Ratio of weight of liquid intake(1 month)
- Number of days that the app was used(1 month)
- Number of days that the app was used by day of the week(1 month)
- Number of days that the app was used by dialysis or non-dialysis days(1 month)
