Applying User-Centered Design and Implementation Science to the Early-Stage Development of a Telehealth-Enhanced Hybrid Cardiac Rehabilitation Program: Quality Improvement Study.

Combining UCD and IS methods while engaging multidisciplinary stakeholders in an iterative process yielded a theory-informed THCR program targeting user and contextual barriers to real-world CR implementation. We provide a detailed summary of the process and guidance for incorporating UCD and IS principles and methods into the early-stage development of a nontraditional CR intervention. The feasibility, acceptability, appropriateness, and usability of the final THCR prototype is being evaluated in an ongoing study.
