The goal of this New Emergency Clearance is to request approval for an investigation is to identify potential risk factors leading to an outbreak of Serratia maraescens infections among US healthcare patients. Data will be used to identify a cause of the infections and prevent additional events from occurring.
On March 27, 2018, the Colorado Department of Public Health and Environment (CDPHE) notified CDC of 4 cases of Serratia marcescens bacteremia among pediatric patients with central lines in an acute care hospital between January 20 and March 23, 2018. This cluster of cases was above the normal baseline of 1–3 cases per year at that facility. The facility examined exposures including common staff and medications and identified commonalities related to the maintenance and care of central lines as well as several medical products including prefilled normal saline syringes and prefilled heparin flushes.
On March 28, CDPHE issued a call for cases to other state and local health departments through the Epidemic Information Exchange (Epi-X) system. On March 29, the Tennessee Department of Health (TDH) notified CDC of 3 cases of Serratia marcescens bacteremia in pediatric patients with central lines in a pediatric hospital between March 6 and March 21, 2018; initial examination of medications and common products identified central venous catheter line products as a possible source of infections, including prefilled heparin and normal saline syringes.
CDC is currently conducting a multistate investigation to support state health departments. Currently, eight state health departments have reported a total of 26 cases to CDC.
Serratia marcescens is a Gram-negative bacillus that can be found in the environment and thrives in moist environments. In healthcare settings, it can be found on the hands of healthcare workers and as a contaminant of medical products and devices, particularly aqueous products. It is a known cause of healthcare-associated infections, particularly urinary tract infection, wound infections, and bloodstream infections, and it is an important opportunistic pathogen in neonatal and pediatric intensive care units. Serratia marcescens has been implicated previously in multistate outbreaks of bloodstream infections caused by intrinsic contamination of prefilled syringes of heparin and isotonic sodium chloride solution.
Submission of 0920-18ACN is a New Emergency ICR designed to collect information on the undetermined cause of Serratia marcescens infections in
multiple States.
