Nudging to select single-lumen over multiple-lumen peripherally inserted central catheters (PICCs) in a large safety net system

Abstract

AbstractBackground:Peripherally inserted central catheters (PICCs) are increasingly used for vascular access in inpatient settings. Compared to multilumen PICCs, single-lumen PICCs carry a lower rate of complications, including central-line–associated bloodstream infection and thrombosis. Despite this, multilumen PICCs are still overused.Methods:This quality improvement initiative was implemented across 11 hospitals at New York City Health + Hospitals safety net system. The electronic health record (EHR) interventional radiology or vascular access team consultation orders were modified to allow for lumen choice, with default selection to a single-lumen PICC.Results:Average single-lumen PICC utilization increased by 25.5%, from 44.4% to 69.9% (P < .001). CLABSI rates had a nonsignificant reduction by 26.7% from 2.44 to 1.79 infections per month (P = .255). Among provider types in the postintervention period, single-lumen PICC utilization ranged from 67.7% for advanced practice providers to 82.4%–94.6% for physicians. Among provider specialties, utilization ranged from 31.8% for neurology to 97.7% for orthopedics. Additionally, there was large variation in pre- and postintervention differences in utilization by hospital.Conclusions:We successfully increased single-lumen PICC utilization across all 11 safety net hospitals. This expands on previous work on improving single-lumen PICC use and use of default nudges in large, resource-limited settings. Further study is needed to examine variation among provider types, specialties, and hospitals.
