The A09 and A10 (patient arriving tracking) events are used when there is a change in a patients physical location and when this is NOT a change in the official census bed location. There are three situations that qualify as non-census location changes: (a) patient tracking, (b) the patient is in transit between locations for some time, (c) a notification of temporary location change.
Patient tracking: This can be used when the nursing application sends a "transfer" before the ADT (or official census) system issues an A02 (transfer a patient) event. If the patient has left for a non-temporary location and is not in transit, then the PV1-3-assigned patient location must contain the new patient location, while PV1-6-prior patient location must contain the old patient location.
In transit: The patients location during the time between an A09 and an A10 is defined as "in transit." The A09 event is sent when a patient departs from one area of the facility for the purpose of arriving at another area, but without leaving the healthcare institution. This event is used when there is a time span during which the patient is neither at his/her old location nor at his/her new location. This process can take some time if a patient is being sent to another area in a multi-campus or multi-facility environment. The combination of an A09 and an A10 would serve the same purpose as an A02 (transfer a patient) event, except that it accounts for a gap in time required for transport between facilities. If the patient will be in transit during the time between the A09 (patient departing tracking) event and the A10 (patient arriving tracking) event, then PV1-42-pending location is used for the new location, and PV1-11-temporary location and PV1-43-prior temporary location would not be used. PV1-6-prior patient location should be used for the old location.
Temporary location: An A09 can also be used when the patient is being sent to a temporary location (such as the O/R, XRAY, LIMBO, or HALLWAY). The patient may or may not return to the same assigned location after occupying the temporary location. If the patient is going to a temporary location (such as the O/R, XRAY, LIMBO, or HALLWAY), then PV1-11-temporary location is used to indicate the new temporary location. If the patient is moving from one temporary location to another, then PV1-43-prior temporary location may also be used. PV1- 6-prior patient location and PV1-11-temporary location should be used when the patient is moving from a permanent location to a temporary location.
The fields included when this message is sent should be the fields pertinent to communicate this event. When other important fields change it is recommended that the A08 (update patient information) event be used instead.
