Accurately inquiring about the allergy histories of hospitalized patients and labeling those with allergies is crucial for preventing potential adverse allergic reactions. Patients’ allergy statuses should be communicated through both identifying wristbands, such as red wristbands, and alert systems on digital patient records. We believe that educational programs should be implemented to increase the knowledge levels of both patients and healthcare professionals regarding allergy labels and that protocols related to allergy labeling should be developed in healthcare facilities.
