A Pilot Randomized Controlled Clinical Trial to Test the Feasibility, Acceptability, and Usability of iPREPARED; A Mobile Health Technology for Patients and Care Partners

Abstract

Background: Family participation in the delivery of nonpharmacological measures has shown in past studies to prevent 17-75% of incident delirium. A scalable and sustainable method to partner with family (i.e., care partners) and support their delivery of nonpharmacologic measures is needed. Objectives: To test the feasibility, acceptability, and usability of iPREPARED in a pilot randomized controlled clinical trial (RCT). iPREPARED is a mobile health technology co-designed with patients and care partners containing resources on nonpharmacological interventions to prevent delirium. Methods: Hospitalized adults (≥65 years) with ≥1 delirium risk factor and a care partner (family or friend ≥18yo) willing to participate were enrolled. The primary outcomes were feasibility, acceptability, and usability. Descriptive statistics are reported. Results: In total, 23 dyads completed the study (median age 72 years (IQR 64, 79), 60% male, and 100% Caucasian). Dyads reported that iPREPARED was acceptable, with moderate usability. Recruitment in the emergency department was feasible whereas recruitment once hospitalized and admitted was more difficult. Conclusion: The study design was feasible. iPREPARED was acceptable and usable as an intervention.
