The patient identification process is essential to ensure safety and quality of assistance in healthcare institutions. The use of a wristband for identification is common practice, although cultural organization, material and human factors cause non-conformity resulting in errors or adverse events. The aim of this article is to highlight constituent elements of the patient identification process by means of wristbands and discuss topics related to the implementation of this process in hospitals. This study was based on theoretic references and standardizations of accrediting organizations and bodies that debate security in the hospital environment and incentives for safe patient identification. It was concluded that patient identification by means of wristbands is recommended internationally although there are loopholes in relation to protocol, effective execution and evaluation of the process to support management and healthcare actions.
