sipIT2: Improving Adherence to Fluid Intake Guidelines for Kidney Stone Prevention

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.
