Outbound patient identification fields
Patient ID information is confirmed at the Acuity Central Station in the Patient ID Setup
window. WACS forwards an outbound patient ID segment that includes at least one of
these ID fields: PID-2, PID-3, and PID-18. By default, all of the fields are populated.
Export multiple ID fields from WACS, such as name and ID number. This enables
detection of obvious identification errors. Since monitors can move easily from location to
location, patient room number alone is an unreliable means of identifying patients.
WACS can export these patient ID fields:
• Patient ID number: A primary identification number, such as a medical record number,
account number or a patient’s personal ID number (such as a social security number).
If this number is input incorrectly, it cannot be altered.
• Amended patient ID number: An alternate ID that can be associated with the patient.
This ID can be entered in the Acuity System Patient ID Setup window, in the
Amended ID field.
• Patient last name
• Patient first name
• Patient middle initial
• Patient location: A room number
Note The Acuity System accepts middle initial only (not middle name).
