Iachine et al reported a prediction model for central venous catheter tip colonization. This can help to identify a patient at greater risk. The authors are from Caen University and multiple institutions in the Europe and the United States.
Patient selection: central venous catheter
Parameters:
(1) obesity (BMI > 30 kg per square meters)
(2) diabetes
(3) insertion site
(4) dialysis catheter
(5) first catheter inserted
(6) dwell time in days

total score =
= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 12
• A score >= 6 is associated with higher risk of tip colonization.

Performance:
• The area under the ROC curve is 0.69.
• The ability to colonize the catheter tip varies with different pathogens.
