Healthcare. In healthcare, solutions like ETA are sometimes called "clinical decision support systems". The first version of ETA has been in use for several years monitoring diabetes meters. Events come from multiple types of meters. Rules (called "clinical protocols") are based on single readings or patterns of readings. These rules trigger a variety of actions - including notifying 7x24 hour nurse call centers who can dispatch 911 services for dangerous readings. This production solution has been a part of saving lives, something our team is very proud of and strives to improve with each new release.
