abstract
BACKGROUND: Weight loss surgery is safe and effective, but fluid and electrolyte balance remains problematic postoperatively. We developed a mobile app to help patients recover after weight loss surgery. MATERIAL AND METHODS: Single-center prospective, mixed-methods, participatory research design study of eligible English-speaking adults undergoing weight loss surgery was used. Patients used the app for 30 d after surgery. We developed and refined the app from July 2017 to October 2018. The principal component of the app is a daily survey designed to assess patients' recovery. The app was revised based on patient feedback, and we compared app utilization between initial and updated versions of the app. Primary outcome was successful patient engagement, which we defined as 80% of patients completing at least 70% of the surveys. RESULTS: Ten patients completed the trial period, four with the initial version of the app, and six with the updated version. All patients expressed satisfaction with the app and most frequently reported that push notifications were helpful. We found that one (25%) patient completed at least 70% of the surveys in the initial version of the app. In the updated version, five (83.3%) of patients completed at least 70% of the surveys, passing our criteria for successful engagement. CONCLUSIONS: Participatory research design in app development requires continuous evaluation and refinement to patient and clinician needs. This effort is essential as we observed significant improvement in app utilization. Our next step is to pilot the app in a larger set of patients to assess utility and feasibility.
