BackgroundInappropriate use of peripherally inserted central catheters (PICCs), including multilumen PICCs, may increase the risk of patient complications.ObjectiveImplement computerized decision support to: (a) increase the use of midline catheters over PICCs when appropriate and (b) decrease PICC lumens when a PICC is necessary.DesignsQuasi-experimental, interrupted time series.SettingSingle tertiary academic medical center.PatientsHospitalized adults who received a midline or PICC during clinical care.InterventionDecision support on appropriate vascular access device choice via a set of electronic orders embedded within the electronic health record.MeasurementsProportion of midline catheter and single-lumen PICCs placed between January 2, 2017 and November 19, 2017 (preintervention) versus November 20, 2017 to December 1, 2019 (postintervention).ResultsA total of 8758 midline and PICCs were inserted during the study period. A statistically significant increase in the insertion of midline catheters was observed during the intervention (p = .006). In parallel, single-lumen PICC insertion as a proportion of all PICCs also increased after the intervention (p = .035). Results were consistent across multiple disciplines, including internal medicine, surgery, and intensive care. After considering the hospital census, total PICC and midline utilization rates and rates of complications did not change over time. However, an increase in catheter exchanges from less to more invasive devices occurred.ConclusionsIn this single-center study, the implementation of electronic decision support to inform appropriate catheter use led to a more appropriate midline catheter and single-lumen PICC insertion. Dissemination of this single, effective intervention to examine efficacy in other hospital settings would be welcomed.© 2023 Society of Hospital Medicine.
