Systems and methods are provided for wearable patient identifiers. One embodiment is a labeling system that includes an interface, a memory storing rules that indicate on a patient-by-patient basis whether to print clinical notifications onto wearable patient identifiers, based on fields of electronic health records acquired via Health Level 7 (HL7) messaging, and a controller. The controller presents a Graphical User Interface (GUI) that includes interactive elements that enable alteration of the rules. The interactive elements include, for each rule: a first dialogue that indicates a field storing data to acquire from an electronic health record; a second dialogue that indicates a value to compare to the data; and an operator that logically combines the data and the value to arrive at a Boolean result. The controller determines whether to include a clinical notification in print data for a wearable patient identifier, based on the Boolean result.
