Germany's healthcare system is introducing TI-Messenger, an encrypted messaging service overseen by Germany’s National Digital Health Agency, Gematik, to enhance communication among patients, healthcare professionals, and insurance companies. This service aims to replace traditional communication methods like faxes and phone calls, with initial trials showing significant time savings for medical staff. TI-Messenger, based on the Matrix open network technology standard, is designed to allow secure communication across health institutions while maintaining data control. As of July 15, 2025, it became accessible to all German citizens with public health insurance. A trial in Hamburg demonstrated that pharmacists significantly reduced phone calls by using TI-Messenger. There are two versions of the service: TI Messenger ePA for citizens and TI-Messenger Pro for healthcare professionals, which has not yet seen widespread adoption. Challenges in user adoption exist, with potential solutions including financial incentives and simplified onboarding processes. Future developments may lead to automated responses and improved communication practices, with hopes for collaboration with other European countries using similar technologies.
