Sara Gehder's research focuses on advancing the integration of patient-centered digital health applications into healthcare delivery. Her work explores innovative approaches to evidence generation, with particular emphasis on real-world data (RWD) and its potential to demonstrate the effectiveness of mHealth applications in improving care. Sara is also deeply interested in the regulatory and implementation frameworks that facilitate the adoption of digital health solutions, such as Germany's Fast-Track Approval Process for Digital Health Applications (DiGA) under the Digital Healthcare Act. Her current projects investigate the use of RWD to capture the nuanced impact of mHealth interventions, addressing challenges in transitioning from traditional evidence models like randomized controlled trials to more dynamic and continuous performance monitoring. Additionally, she explores the broader conceptualization of efficacy, examining how patient-relevant structural and procedural improvements can drive healthcare innovation. Through this work, Sara investigates barriers to the adoption of patient-centered digital health solutions and identifies pathways to facilitate their inclusion in statutory healthcare systems worldwide.
