Abstract：Objective:Based on HFMEA theory,to construct a risk assessment scale for unplanned extubation of tracheal intubation in ICU adults based on HFMEA model and to test the validity and reliability.Methods:Through literature review,clinical data analysis,HFMEA team members screening,decision tree analysis,and clinical pre-investigation,the"Risk Assessment Scale of Unplanned Extubation for Adult Tracheal Intubation in ICU"was formed.Using convenient sampling method,a total of 526 patients with tracheal intubation in ICU in a tertiary grade A hospital in Jiangxi province were selected for scale investigation and reliability and validity test from April to October 2022.Results:The formal scale included patient factor,catheter factor,lack of effective supervision and other factors,with 13 first-level items and 41 second-level indicators.The Cronbach's alpha coefficient was 0.745,the inter-rater Spearman correlation coefficient was 0.936(P<0.001),the I-CVI was in the range of 0.80～1.00,and the S-CVI was 0.91.KMO=0.666,χ2= 1191.556,df=78,P<0.01,a total of 4 common factors were extracted,with a cumulative variance contribution of 53.23%.Conclusions:The reliability and validity of the constructed Risk Assessment Scale of Unplanned Extubation for Adult Tracheal Intubation in ICU were good,and nursing staff could effectively identify the risk of unplanned extubation in tracheal intubation patients.
