Finally, 16 pieces of best evidence were summarized and categorized into 5 aspects as identification tool/technology management, wristband, photo, identification card, and new tool/technology. Conclusion Evidence users need to combine relevant policies and current status of medical institutions when using evidence, and assess the suitability of patient identification tool/technology, so as to achieve scientific management of patient identification tools/technologies and verify and update the best evidence.
