How does Join integrate with hospital imaging systems to receive and view DICOM images?
A gateway server software is installed on the client environment, taking the qualified images from modalities directly (PACS, etc.), and anonymizes images so no PID (patient indentified information)exsists. The information is then transferred to the Join cloud on AWS or other cloud patners through a secure VPN connection. DICOM images available on the Join cloud will be securely served to users through streaming rather that direct downloads.
How Join can be set up in my institution?
Our team of workflow consultants and IT engineers will carefully listen to the situation of each individual institution and implement Join appropriately according to the existing environment. Please contact us and request your interest in Join.
Can the system be linked to an electronic medical record system?
Yes, you can. Although it is a separate option, possible to import test and prescription information from electronic medical records. Please contact us for details on how to link. In addition, case and time stamp data can be output in CSV and PDF formats from the Join management screen, and can be reflected in the electronic medical record.
How do you ensure safety when using it with smartphones?
Join is a medical device that complies with 3 ministries and 2 guidelines and is approved for medical devices; it allows speedy viewing of medical images in DICOM format and prevents accidental leakage from the device, as images are never downloaded from the cloud to the device. It has a high level of security for handling medical information, including appropriate encryption and anonymization of data, as well as OS authentication with additional authentication at the application layer.
How can hospital control who sees what in Join?
Once Join is installed in a hospital, an administrator (or multiple administrators) within the hospital is appointed to create and manage groups (also called chat rooms) on Join. Groups are usually created to include all members of a care team for a certain condition or department. The administrator can create groups, add members, and delete members.
Is it possible to intergrate with exising systems?
Join has an integration function that allows you to launch the Join application from other applications or web systems and share messages. Other linking functions require separate system development. Please contact us for more details.
