1174. The Impact of Multidisciplinary Central Line Stewardship Program to Decrease CLABSI Rates and Central Line Utilization Rates in an Academic Urban Medical Center

Abstract

BackgroundCentral Line-Associated Blood Stream Infections (CLABSI) is a major healthcare dilemma, contributing to increased morbidity, mortality, and costs. We sought to reduce rates of CLABSI and device utilization by implementing a multidisciplinary Central Line Stewardship Program (CLSP).MethodsIn July 2017, the CLSP, multidisciplinary quality improvement project, was implemented at an academic medical center to ensure proper indication for all CVCs in the hospital and removal when no longer indicated. A CLSP team of executive leaders and infection preventionists performed daily rounds on all CVCs to review indications and maintenance. Nursing staff reported all CVCs daily. Information Technology modified the electronic health record to require daily physician documentation of CVC placement and indications, and to suggest alternatives to CVC when possible. In the event of a CLABSI, a root cause analysis was conducted within 72 hours, and feedback was shared with the clinical staff. A retrospective review was conducted 18 months before and after CLSP implementation. As a facility in a state with mandatory reporting of hospital-acquired infections, institutional data were readily available through the National Healthcare Safety Network (NHSN). To compare rates of CLABSI and device utilization pre- and post-CLSP, we reviewed the Incidence Density Rate (IDR), the standardized infection ratio (SIR), and standardized utilization ratio (SUR). Data from the NHSN website were analyzed using statistical tools provided by the NHSN analysis module. Two-tailed significance tests were conducted with α set at 0.05.ResultsPost-CLSP, there was a statistically significant decrease in SIR from 1.99 to 0.885, with risk reduction by 44.3% (P = 0.013, 95% CI 0.226 -0.831). CLABSI IDR per 1000 CVC days declined from 1.84 to 0.886 (P = 0.0213). CVC utilization per 1000 patient-days reduced from 155.08 to 142.35 (P < 0.001). There was also a trend toward fewer PICC line infections post-intervention (17 to 5).ConclusionWith this novel CLSP, we achieved a significant reduction in rates of CLABSI and device utilization, suggesting that a multidisciplinary approach can promote sustainable prevention of line-associated infections through dedicated surveillance of CVC indications and maintenance.
