ORU - Unsolicited Point-Of-Care Observation Message Without Existing Order - Place An Order

One example of this trigger's use case occurs when a Doctor verbally instructs a nurse to perform a test. Looking at this use case from an information management perspective, one might expect that, the nurse would enter an order into laboratory information or ordering system before performing the test. However, there usually isn't time for order entry in these use cases. In fact, it is highly desirable for the POC measurement process to become automated so that the only action a user needs to take is to make a measurement on the POC Device, with all other processes for generating an order and tying it in to the observation handled by the "machines."
