The field of infection prevention is set to take a major leap forward, thanks to a groundbreaking new system developed by researchers at the University of Pittsburgh. Known as the Enhanced Detection System for Healthcare-Associated Transmission (EDS-HAT), this innovative technology utilizes the power of advanced genomic sequencing to analyze infections among hospital patients. The system is particularly adept at flagging situations where nearly identical strains suggest transmission between patients, rather than independent infections from external sources.
Spearheading this pivotal development is Alexander Sundermann, an assistant professor of infectious diseases at Pitt’s School of Medicine. Sundermann explains that EDS-HAT is far from theoretical. It has already demonstrated its merit in a real-world setting, saving lives, curbing the spread of diseases, and curtailing healthcare costs.
In a two-year trial conducted at UPMC Presbyterian Hospital from November 2021 to October 2023, the system successfully preempted 62 infections and saved five lives, as compared to traditional detection methods. Furthermore, EDS-HAT contributed to nearly $700,000 in avoided treatment costs, marking an impressive 3.2-fold return on investment. Without this tool, infection preventionists find it challenging to distinguish whether patients with the same infection acquired it from a shared source or by mere coincidence. The EDS-HAT system eliminates this uncertainty, aiding in curbing undetected outbreaks and conserving resources otherwise wasted in investigating non-existent transmission patterns.
Envisaging future applications, the research team is optimistic about the system’s nationwide implementation. Adopting EDS-HAT across health care facilities could pave the way for a national outbreak detection network akin to PulseNet, the CDC’s system for tracking foodborne illness. This has the potential to early identify and prevent outbreaks, such as the 2023 bacteria spread linked to contaminated eye drops.
In the face of mounting pressure on healthcare facilities to prevent hospital-acquired infections and elevate patient safety, technological interventions like EDS-HAT present a practical solution. They offer a balanced approach to improved patient outcomes, along with financial sustainability – a duo rarely achieved in healthcare innovation today. The researchers’ study, which provides substantial evidence advocating for genomic surveillance as standard practice, appears in the April 28, 2025, issue of Clinical Infectious Diseases.
