There was a sudden and unexpected malfunction of our alarm system. Despite existing backup plans, there were delays, parts of the stroke team were alerted belated or not at all. In the current case, we were lucky enough to be in the test phase for Join. With the help of the app, we were able to ensure communication with the ambulance and communication within the hospital quickly and efficiently. So there were no delays during the 48-hour outage. Thanks to Join we were able to continue working without any loss of speed or quality.
