Join tackles major challenges occurring during intra- and inter-hospital communication for multidisciplinary teams: When the life of the patient is on the line, Doctors need to make quick decisions based on the information and medical images they have at hand – communication is key. But expertise and knowledge are not evenly distributed and not always available without losing valuable time. Join closes this communication gap and provides both smooth communication and mobile access to medical images, e.g. from modalities or PACS via the embedded DICOM viewer. Specialists are thus able to help their colleagues with proper instructions, even if they are not on the site. Of course the app follows privacy policies and is fully GDPR-proof.
