A comparison of the incidence of midline catheter–associated bloodstream infections to that of central line–associated bloodstream infections in 5 acute care hospitals

In a retrospective study conducted over 12 months in a multi-hospital system, the incidence of bloodstream infections associated with midline catheters was not significantly lower than that associated with central venous catheters (0.88 vs 1.10 infections per 1,000 catheter-days). Additional research is needed to further characterize the infectious risks of midline catheters and to determine optimal strategies to minimize these risks.
