Complications associated with the use of peripherally inserted central catheters and midline catheters in COVID-19 patients: An observational prospective study.

BACKGROUND: Among the many interesting aspects of clinical care during the SARS-CoV-2 pandemic, vascular access still deserves some attention. Peripherally inserted central catheters (PICCs) and midline catheters (MCs) are venous access devices inserted by ultrasound-guided puncture of veins of the arm, which have been associated with the possibility of minimizing infectious complications in different populations of patients. We have investigated their performance in SARS-CoV-2 patients. METHODS: As the incidence of catheter-related bloodstream infections (CRBSI) in patients hospitalized for COVID-19 is still unclear, we have designed a single-center, prospective observational study enrolling all patients with established diagnosis of SARS-CoV-2 infection who were admitted to our hospital in the period between October 2020 and April 2021 and who required either a PICC or a MC. RESULTS: We recruited 227 patients. The cumulative incidence of CRBSI was 4.35% (10 cases), that is, 3.5 episodes/1,000 catheter days. Four CRBSI occurred in patients with PICCs (4.5/1,000 catheter days) and 6 in those with MCs (3.2/1,000 catheter days). CONCLUSIONS: Our data suggest that COVID-19 patients may have a more pronounced tendency for the development of catheter-related infections compared to other populations of patients.
