Risk-benefit evaluation of established messenger apps for clinical practice - is secure communication via smartphone possible? (Preprint)
BACKGROUND The establishment of smartphones as the most important communication medium of the 21st century has led to usage of mobile messenger services also in the medical context. However, the use of the most commonly used smartphone-app WhatsApp in a medical treatment context represents an incalculable risk from a legal point of view (data protection) and can ultimately lead to a violation of medical confidentiality with potential legal consequences. OBJECTIVE Therefore, this study aimed to assess which alternatives in terms of messenger applications exist for secure communication of patient-related data. METHODS A systematic literature and online “Appstore” search was conducted to identify secure messenger services. These had to comply with currently valid technical and legal formal specifications in terms of data security as well as to provide similar usability and functions as WhatsApp. RESULTS A total of 13 messenger apps were identified. However, only 5 apps (Famedly, JOIN, Siilo, Threema and Trustner) met the formal requirements as a secure communication medium. JOIN is the only service which has been approved by the FDA and is classified as a medical device. CONCLUSIONS The current practice of rather random and unstructured use of messenger apps in everyday hospital life should be a thing of the past. From today's perspective, the apps Famedly, JOIN, Siilo, Threema and Trustner are recommended. They have considerable advantages over the apps used in everyday clinical practice today (like e.g., WhatsApp). The rapid developments on the software market will certainly drive further developments, so that the recommendation formulated here is only a snapshot.
