Groups2
Group 2 names the comparator: control.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Intervention | Participants in the intervention arm will receive an individualized fluid prescription, which will be the additional volume of fluid intake needed to maintain a study-specified urine output. This fluid will be consumed from and measured by a smart water bottle. The intervention arm also includes a behavioral program that consists of financial incentives and structured problem solving (SPS) to maintain the recommended fluid intake.~Fluid prescription: The additional amount of fluid that the participant will need to consume each day, using the smart water bottle, in order to meet the study-specified urine output. This fluid is in addition to any other sources of fluid (ex. cups of coffee, bottled sports drink) that the participant consumes each day.~Financial incentive: Participants in the Intervention Arm who meet their fluid intake goal on randomly selected days will receive a small payment for that day.~Structured Problem Solving: Structure Problem Solving involves interactions with health coaches to help participants develop feasible solutions to overcoming personal barriers to maintaining the prescribed fluid intake. | 0 | 826 | EG000 |
| Group 2 | Control | Participants in the control arm will receive standard care instructions according to American Urological Association (AUA) guidelines to increase overall fluid consumption to achieve study-specified urine output. They will also receive a smart water bottle with capability to self-monitor their fluid intake. | 2 | 832 | EG001 |
