Central venous catheter tip misplacement: A multicentre cohort study of 8556 thoracocervical central venous catheterisations.

BACKGROUND: There is a paucity of data on the incidence of central venous catheter tip misplacements after the implementation of ultrasound guidance during insertion. The aims of the present study were to determine the incidence of tip misplacements and to identify independent variables associated with tip misplacement.

METHODS: All jugular and subclavian central venous catheter insertions in patients ≥16 years with a post-procedural chest radiography at four hospitals were included. Each case was reviewed for relevant catheter data and radiologic evaluations of chest radiographies. Tip misplacements were classified as 'any tip misplacement', 'minor tip misplacement' or 'major tip misplacement'. Multivariable logistic regression analyses were used to investigate associations between predefined independent variables and tip misplacements.

RESULTS: A total of 8556 central venous catheter insertions in 5587 patients were included. Real-time ultrasound guidance was used in 91% of all insertions. Any tip misplacement occurred (95% confidence interval) in 3.7 (3.3-4.1)% of the catheterisations, and 2.1 (1.8-2.4)% were classified as major tip misplacements. The multivariable logistic regression analyses showed that female patient gender, subclavian vein insertions, number of skin punctures and limited operator experience were associated with a higher risk of major tip misplacement, whereas increasing age and height were associated with a lower risk.

CONCLUSIONS: In this large prospective multicentre cohort study, performed in the ultrasound-guided era, we demonstrated the incidence of tip misplacements to be 3.7 (3.3-4.1)%. Right internal jugular vein catheterisation had the lowest incidence of both minor and major tip misplacement.
