Abstract：Objective To construct a prediction model for the optimal placement length of peripherally inserted central venous cathe-ters(PICC)in the upper limbs of adult cancer patients.Methods Clinical data of 7 331 adult cancer patients who underwent PICC catheter placement in a hospital from April 2020 to April 2024 were selected.The main factors affecting the optimal length of central venous catheter insertion were screened out by univariate and multivariate analysis.The prediction model was constructed based on the influencing factors and the prediction effect of the model was verified.Results Height(OR=6.017),body mass index(OR=2.443),the inserted vein(OR=94.780),and predicted length(OR=3.064)were the influencing factors for the tip position of the PICC catheter in adult cancer patients(P＜0.01).Based on the above influencing factors,the prediction model was established as Y=6.581+0.098×height+0.015×body mass index-0.630×the insert-ed vein+0.458×predicted length(R2=0.232,F=441.255,P＜0.001).Conclusion The model constructed based on intracavitary electrocar-diographic localization in adult cancer patients demonstrates strong predictive capabilities for predicting the optimal insertion length and tip positioning of PICC catheters,providing a theoretical basis to avoid repeated intraoperative adjustments of the catheter during surgery.
