With advances in intensive care, more patients are surviving from critical illness, and post-intensive care syndrome (PICS) began to get people's attention. Early detection and intervention of PICS can improve the quality of life of intensive care unit (ICU) survivors and reduce the rate of re-hospitalization. However, effective, reliable, and easy-to-use assessment tools are the basis for early detection and evaluation of intervention outcomes. Thus, we introduce the evaluation tools for PICS from the perspective of universality or specificity, aim to provide reference for doctors or nurses to choose suitable assessment tools for PICS, and to provide reference for the development of localized assessment tools for PICS in China, so as to promote the related research of PICS.
