A colored wristband application is used in the hospital for the correct identification of patients. All standard patients hospitalized in the health institution are given a white identification wristband, while only patients with a history of allergy are provided with a red colored wristband. Allergy history is questioned by the physician and nurse at the first admission of all patients, and if a history of allergy is present, the patient is given a red identification wristband. In addition, automatic warning screens are activated by entering allergy information on the HIMS patient card panel. Patients reporting a history of allergy are not routinely tested for allergy; decisions are made based on the patient’s statement or previous clinical findings.
