Note: PICC refers to peripherally inserted central venous catheter; BMI refers to body mass index; malignant tumor refers to cases treated within the prior six months; recent surgery refers to neurosurgery (over two hours) performed within six months; critical illness refers to the circumstance where patients have a high risk of disease variation or death
