In addition to the initial consultation, many other factors are relevant for a correct diagnosis in psychotherapy, such as current medication or earlier diagnoses. The Telematics Infrastructure (TI) and the electronic patient file have been set up for the healthcare industry in order to provide this overview of health in a fast and efficient manner. The Telematics Infrastructure links all stakeholders in the healthcare industry – doctors and dentists, hospitals, statutory health insurance companies, psychotherapists and pharmacies – and enables the fast and easy delivery of all medical information relevant to the treatment of patients. With the Act for Secure Digital Communication and Applications in Healthcare (eHealth Act), the legislator decided to introduce a secure digital infrastructure for the healthcare system. All service providers are obliged to connect to the telematics infrastructure. This requires a connector and a card terminal, which can be used together with the SMC-B card for medical practices and the electronic health professional card (eHPC) to enable a legally binding signature and authentication of your practice or of the therapist within the telematics infrastructure. D‑Trust is a qualified trust service provider and approved producer of the SMC-B card for medical practices and the electronic health professional card (eHBA).
