Developing telemedicine in Emergency Medical Services: A low-cost solution and practical approach connecting interfaces in emergency medicine.

Background: In Germany, the number of calls for Emergency Medical Services (EMS) are increasing, while the number of general practitioners and hospitals are decreasing, resulting in a growing demand and workload for emergency physicians and paramedics. Furthermore, an aging population with increasingly complex medical histories, present emergencies in which a more detailed assessment and therapies are urgently needed. Therefore, common EMS systems need to find solutions to handle these problems.

Methods: We used a user-focused five-step approach to define a technological solution: Research of current systems, definition of goals and requirements, development of concept, test series and evaluation, evaluation of costs and benefits.

Results: Development of a holistic telemedical concept to connect in-hospital clinical emergency physicians and paramedics on the scene, by implementing and connecting systems that are already partially being used in common EMS in Germany. By using live audio and video communication, including vital signs between the two, a system can be established by keeping costs low, affordable and at the same time protecting patient data in line with General Data Protection Regulation.

Conclusion: Implementing technologies in a practical specialty like Emergency Medicine with a user-focused approach demonstrates that the hurdle for integration into established routines can improve current processes. Evaluation of costs and usability is a main driver to define success of such concepts and can improve if such systems can be developed to be used in larger networks.
