Clinical Trial Summary

The purpose of this study is to examine the feasibility of using sipIT tools (i.e., wrist-worn sensors, smart water bottles, mobile applications) to increase compliance with physician-recommended fluid consumption guidelines in participants with a history of urolithiasis.

Description:

The study uses a randomized controlled trial design with a 12-month intervention period and outcome assessments at baseline, 1, 3, and 12 months. Participants will be randomly assigned to groups. Both groups will receive usual care which involves education about fluid intake guidelines and encouragement to adhere to those guidelines from a clinician. The intervention group will additionally receive the sipIT intervention comprising a semi-automated fluid intake tracking system and context-sensitive, just-in-time notifications reminding them to drink.

Eligibility

Inclusion Criteria:

• pregnant or planning to become pregnant in the next 12 months,

• concurrently participating in another study involving fluid intake or diet,

• plan to have surgery or relocate outside the area within the next year

• co-morbidities that preclude high fluid intake, conditions with high fluid losses (e.g., congestive heart failure, bariatric surgery, GI tract ostomy, short gut syndrome, chronic diarrhea including patients with ulcerative colitis/Crohn's disease, hyponatremia), or conditions that preclude ability to collect 24-hour urine (severe urinary incontinence),

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	24-hr urine volume	Change in urine volume from baseline	3 months
Secondary	24-hr urine volume	Change in urine volume from baseline	1 month and 12 months
Secondary	Urine supersaturations	Change in supersaturations of common stone-forming salts from baseline to 1/3/12 months	1 month, 3 months, and 12 months
Secondary	Habit strength for fluid intake	Change in habit by the 4-item Self-Report Behavioural Automaticity Index (Gardner, Abraham, Lally & de Bruijn, 2012, Int J Beh Nutr Phys Act; baseline to 3/12 months). Responses will be averaged so scores range from 1 (strongly disagree) to 7 (strongly agree) with higher scores indicating stronger habits for fluid intake.	3 months, and 12 months
Secondary	Past-week fluid intake	Change in past-week volume of fluid intake from baseline to 3/12 months	3 months, and 12 months
