Objective A scoping review was performed to examine the risk prediction instruments of psychological disorder of ICU discharged patients,in order to provide references for clinical nursing practice and further research. Methods The PubMed,Embase,Web of Science core collection,CNKI,China Biology Medicine and WanFang Database were searched from inception to July 11,2021. 2 researchers independently screened the literature,extracted the information,and assessed the risk of bias and applicability by the prediction model risk of bias assessment tool and quality assessment of diagnostic accuracy studies-2. Results 6 studies were involved in the final review,including 2 model development studies and 4 validation studies on the effectiveness of screening instruments. Conclusion The risk prediction instruments of psychological disorder of ICU discharged patients had higher predictive performance,but there was also a high risk of bias in the included studies. It is recommended that further examination,verification and development of the existing instruments should be conducted,in order to build a localized prediction instrument with low risk of bias and high applicability.
