Current Use, Challenges, Barriers, and Chances of Telemedicine in the Ambulatory Sector in Germany—A Survey Study Among Practicing Cardiologists, Internists, and General Practitioners

<b>Introduction:</b> Digital technologies, such as telemedicine and wearable devices, are transforming health care by enhancing cross-sectoral care and targeted health responses. Despite these advancements, challenges such as data protection, lack of interoperability, reimbursement, and financial costs hinder telemedicine's broader implementation, especially within the German health care system. This study explores the use, acceptance, and barriers of telemedicine among cardiologists, internists, and general practitioners in Germany. <b>Methods:</b> A web-based survey was conducted from October 2023 to January 2024, targeting cardiologists, internists, and general practitioners. The survey assessed current telemedicine usage, acceptance, and barriers. Data analysis included descriptive statistics and exploratory cluster analysis. <b>Results:</b> Of the 172 physicians analyzed, 76.2% were cardiologists. Telemonitoring (45.9%) and wearable devices (26.2%) were the most used telemedicine applications, whereas video consultations (11.0%) and apps (19.2%) were less common. Despite high costs (57.7%), insufficient technical expertise (20.8%), and lack of system interoperability (45.8%), respondents rated telemedicine positively and saw several chances and potentials. Cluster analysis identified four user groups: The pioneers, the focused practitioners, the using skeptics, and the uninformed distanced, each with unique needs and challenges. <b>Discussion:</b> The acceptance of elemedicine among physicians indicates recognition of its benefits for patient care. Only half of the respondents felt reasonably well informed about telemedicine. Overall, our study shows the current use of telemedicine as well as the acceptance, barriers, and challenges perceived in the German ambulatory sector. It underlines the increasing importance of telemedicine for patient care and highlights existing barriers to enable wider implementation in the outpatient sector. The results show that telemedicine in Germany is on a promising path. The biggest obstacles still appear to be reimbursement and the technical infrastructure.
