Routes of access of causative microorganisms Intraluminal migration Extraluminal migration Contaminated catheter hub - Patients skin flora - HCP hands Skin organisms - Patients skin flora - HCP hands - Contaminated disinfectant 60% 12% <1% Contaminated infusates Contaminated infusate - Extrinsic (Fluid, Medication) - Intrinsic (Manufacturer) Insertion site colonisation Unknown – Local infection and heamatogenous seeding as well as 1,2,3. So how do the microorganisms gain access to the catheter to initiate infection? By gaining access to the extraluminal or intraluminal surface of the device where they become incorporated into a biofilm that allows sustained infection and haematogenous dissemination . Contamination from fluid infused/administered through the device is rare and is the most likely cause of epidemic BSIs but catheter related infections are the cause of most endemic BSIs. Microorganisms gain access by one of the three following mechanisms 1) the microorganisms may be impacted during catheter insertion, invading the percutaneous tract. 2) Microorganisms contaminate the catheter hub (and lumen) 3) organisms are carried haematogenously to the implanted IVD from remote sources of infection, eg pneumonia. Unknown = 28% Haematogenous seeding from distant infection Impaction during insertion Safdar N, Maki DG.
