[Is the discharge letter still relevant? : Chances and risks of "Medical apps" in orthopedics and traumatology].

CURRENT SITUATION: The discharge letter currently represents the gold standard of the information and transfer document in the field of inpatient orthopedic and trauma patient care. In the age of digitization, the smartphone is penetrating more and more areas of life as an omnipresent internet access medium and is thus fundamentally influencing the awareness of our society. Whereas the use of applications on smartphones is already well established today, the range of medical apps is rudimentary. The potential of apps on smartphones as an innovative digital communication medium is undeniable, but the currently available medical apps in orthopedics and trauma surgery are available to a small patient clientele only. FORECAST: Currently, the use of medical apps is not an adequate alternative to the discharge letter. However, it is only a matter of time before the innovative potential of applications is used as a communication tool in outpatient and inpatient care. It is, therefore, essential to start creating the legal, ethical and medical framework and to establish a relevant regulatory body.
