The following is a summary of “Feasibility of Mini sipIT Behavioral Intervention to Increase Urine Volume in Patients With Kidney Stones,” published in the SEPTEMBER 2023 issue of Urology by Streeper, et al.
For a study, researchers sought to assess the feasibility and acceptability of a novel intervention called mini sipIT, designed to improve fluid intake adherence among kidney stone patients. Mini sipIT is a context-sensitive reminder system that combines a connected water bottle with a mobile app and text messaging.
A 1-month single-group feasibility trial was conducted involving patients with a history of kidney stones with a urine volume of less than 2 L/d. Participants used a connected water bottle and received text message reminders if they failed to meet fluid intake goals. Data on perceptions of drinking behavior, intervention acceptability, and 24-hour urine volumes were collected at baseline and after 1 month.
The study included 26 participants, most female (77%) with an average age of 50.4 ± 14.2 years. Over 90% of participants used the bottle or app daily. Most participants believed that the mini sipIT intervention helped them increase their fluid intake (85%) and reach their fluid intake goals (65%). There was a significant increase in the average 24-hour urine volume after the 1-month intervention compared to baseline (2,006.5 ± 980.8 mL vs. 1,352.7 ± 449.9 mL, t (25) = 3.66, P = .001, g = 0.78), with 73% of participants having higher 24-hour urine volumes at the end of the trial.
The mini sipIT intervention and outcome assessments proved feasible and acceptable to kidney stone patients and resulted in significant increases in 24-hour urine volume. It suggested that digital tools combined with behavioral science may enhance adherence to fluid intake recommendations for kidney stone prevention, although further rigorous efficacy trials were required.
