Safety Checklist Implementation Did Not Reduce Central Venous Catheter Duration in Pediatric Cardiac ICU Patients

The Center for Disease Control recommends prompt removal of nonessential central venous catheters (CVCs) to reduce the risk for central line-associated bloodstream infections. Safety checklists have been trialed to reduce nonessential CVC days, but pediatric studies are lacking. Our specific aim was to detect >10% reduction in mean CVC duration after implementation of a safety checklist addressing CVCs in our unit.

All patients admitted to the Congenital Cardiovascular Care Unit at New York University Langone Medical Center who had a CVC placed between January 1, 2012, and December 31, 2017, were included. We implemented a checklist addressing CVC use in our unit on June 7, 2013, and modified it on March 10, 2016. We analyzed quarterly mean CVC duration and postsurgical CVC duration over the study period using statistical process control charts.

We placed 778 CVCs for 7,947 CVC days during the study period. We noted special cause variation from Q4 2013 to Q2 2014 and a centerline shift in mean CVC duration from 8.91 to 11.10 days in Q1 2015. In a subgroup analysis of the 657 lines placed in surgical patients, there was a centerline shift in mean CVC duration from 6.48 to 8.86 days in Q4 2013.

Our study demonstrated an unexpected increase in mean CVC duration after the implementation of a safety checklist designed to decrease nonessential CVC days. Additional studies are needed to identify the ideal method to detect and remove nonessential CVCs and reduce the risk of preventable harm.
