Patients with urolithiasis (kidney stones) need to consume enough fluids to prevent a recurrence. But most fail to adhere to recommended levels of fluid intake because thirst and motivation alone are not sufficient. Recurrence of stones are painful for patients and costly for the health care system so it is important to find new ways of supporting prevention for these patients.
Existing apps for promoting fluid intake use a restricted range of effortful behavior change techniques (Conroy et al., 2017). We conducted extensive work with patients to understand their needs for effective behavior change. We are developing a technology-mediated behavioral intervention to deliver reminders to drink only when a user has not been drinking regularly. By cutting down on unnecessary reminders and interruptions, we can engage patients in long-term stones prevention, improve quality of life, and reduce health care spending.

Classifying Drinking Gestures
Fluid intake is a challenging behavior to monitor in real-time. We recently conducted studies in the lab and in the wild to develop a digital classifier of drinking gestures using data from wrist-worn inertial sensors by WaveletHealth.
Behavioral Intervention Technology
We are currently developing and evaluating the feasibility of a semi-automated fluid intake monitoring intervention, sipIT. This intervention is for iOS smartphones and connects with Fitbit Versa smartwatches and H2OPal water bottles. Our partners in this effort are Fitabase (San Diego, CA) and West Arête (State College, PA).
