Background: Patients presenting to hospitals often arrive with peripherally inserted central catheters (PICC) in place upon admission. The admitting facility may not be familiar with that device’s history and the unknown risk for bloodstream infection associated with it often prompts requests for device replacement. A blanket approach to “change all lines” must be balanced with the potential for patient discomfort and insertion-related complications. To better inform our approach to prevention, we determined the incidence of central-line–associated bloodstream infection (CLABSI) in adult patients presenting to hospitals in our health system with a PICC present on admission (POA), relative to those who have a PICC placed after admission (PAA). Methods: This retrospective cohort study included all adult hospital encounters at 11 Cleveland Clinic acute-care hospitals lasting > 2 days in 2018 with electronic medical record nursing care flowsheet documentation of a PICC during the stay. Patients whose admission diagnosis was related to intravascular catheter infection, children aged <18 years, and observation unit encounters were excluded. Patients were categorized as having a PICC POA if a nurse selected that option on a PICC flowsheet, otherwise the patient was categorized has having a PICC PAA. Surveillance for CLABSI was performed in all inpatient locations at all hospitals according to the NHSN protocol. Patients with ≥1 CLABSI were matched to encounters by name and date of admission. Repeat infections occurring to the same patient were excluded. Results: Of the 8,827 eligible hospital encounters, 1,799 (20%) involved a PICC POA and 7,028 (80%) had PICCs PAA. Across 11 hospitals, the median proportion of PICC-associated encounters with a device POA was 15% (range, 8%–25%). Moreover, 23 of the 112 CLABSIs (21%) in our cohort occurred in patients with a PICC POA and 89 (79%) occurred in patients with a PICC PAA (Table 1). The overall relative risk of CLABSI, whether the PICC was placed before or after admission, was 1.00 (95% CI, 0.64–1.60). Conclusions: Patients with a PICC present on admission to our hospitals were no more likely to experience a CLABSI than patients who had a PICC placed after admission. Replacing vascular catheters that are POA may not reduce the risk of CLABSI. With up to 25% of PICC-associated encounters having the device POA, universal device replacement at admission would involve hundreds of patients per year at our multihospital health system.Funding: NoneDisclosures: None
