Objective: To evaluate kidney stone patients’ interest in lifestyle behavior modification and a variety of mobile health (mHealth) technologies to improve adherence to fluid consumption recommendations for the prevention of nephrolithiasis. Of particular interest was the acceptability of various intervention components for the design of a stone-specific mHealth technology. Materials and Methods: Using a cross-sectional design, adult patients with a diagnosis of kidney stones (n = 94) were recruited from outpatient clinics to complete a three-part questionnaire. Results: Patients reported being willing to make lifestyle changes to prevent kidney stones (97%). The majority of the patients recalled the recommendation to increase fluid intake (93%) but few monitored their daily fluid intake (30%). Most patients had never installed an app (95%) or owned a device (100%) to help with increasing fluid consumption, but believed an app or device could improve their adherence (72%) and would be interested in using an app or device (86%). The mHealth intervention components most widely perceived as useful included automated lapse detection with notifications, educational materials, self-monitoring tools, scheduler with prompts and/or reminders and/or notifications, connected water bottles and text message reminders to drink. Conclusion: Patients are interested in lifestyle behavior change to prevent stones but technology has not been widely adopted to improve adherence to fluid intake recommendations for stone prevention. This study identified a number of viable mHealth intervention components that should be considered when designing a stone-specific mHealth technology to support adherence to increased fluid consumption recommendations.
