This single-center observational study will record and compare Midline and PICC line catheter-related bloodstream infections in the first 30 days after placement, catheter-related bloodstream infections being defined as clinical signs associated with a positive catheter culture (bacterial culture finding more than 103 CFU/mL) without any other infectious entry points.~Catheter indications, insertion conditions, incidence of haemorrhagic and thrombotic complications during the first 30 days will be analyzed.
A long-term venous access is frequently required in patient management. Currently, it is ensured by using the long peripheral intravenous catheters (Midline) or peripheral inserted central catheters (PICC line). Either is inserted into a peripheral vein of the upper arm and extends to the distal axillary vein.~If the indications for the two catheters can sometimes be debated, the Midline catheter seems to be more and more used. The complications related to the use of PICC lines have been well described in literature, whereas the comparison of the two catheter-related complications has been less analysed.~The aim of this study is to compare the incidences of catheter-related bloodstream infections linked to PICCs and Midlines.
