Perimeter, a biosurveillance specialist, and outbreak detection company Culturewell have launched a joint infection surveillance programme designed to help hospitals identify potential pathogen risks before they develop into healthcare-associated infections (HAIs). The collaboration combines environmental monitoring technologies from both companies to give healthcare institutions a broader picture of infection risks across their facilities.
The partnership brings together Culturewell’s room-level surface sampling capabilities with Perimeter’s building-level wastewater sequencing and biological threat intelligence. The companies said the combined approach is intended to help hospitals identify where pathogens may be circulating, track changes over time and respond to potential risks earlier.
The move comes as hospitals continue to strengthen hospital acquired infection control strategies. HAIs can increase treatment costs, extend hospital stays and place additional pressure on healthcare systems. Traditional surveillance methods can provide important clinical information, but environmental monitoring can add another layer by identifying microbial activity before a pattern becomes apparent through patient diagnoses.
For healthcare institutions, the significance of the partnership lies in connecting information collected at different levels of the hospital environment. Culturewell focuses on surfaces and rooms, while Perimeter examines signals from wastewater systems. Together, the companies aim to create a more continuous view of pathogen circulation rather than relying on isolated sampling events.
The programme also incorporates broader information on biological threats and regional trends. This could allow hospitals to place findings from their own facilities into a wider epidemiological context and potentially distinguish local changes from broader increases in pathogen activity.
Surface Sampling and Wastewater Monitoring Combined
Under the agreement, Culturewell will be responsible for collecting and analysing surface samples from healthcare environments. Its laboratory processes the samples and provides results in approximately 18 hours, according to the companies.
Surface sampling can offer hospitals a highly localised picture of microbial activity. Monitoring areas within individual rooms or clinical spaces may help identify changes that would otherwise remain difficult to detect through conventional infection surveillance.
Perimeter adds a different layer through its wastewater monitoring infrastructure. The company uses continuous metagenomic sequencing and bioinformatic analysis to examine biological material moving through hospital plumbing systems.
Rather than examining only individual patient samples, the system looks for biological signals across the facility. Perimeter said its technology can help characterise pathogens and antimicrobial resistance genes and track their movement at ward and building levels.
The use of wastewater as a source of biological information has attracted growing attention because it can provide an aggregated view of what is circulating within a defined environment. In a hospital setting, this could potentially provide an early signal of changes in pathogen prevalence without requiring every individual to undergo testing.
The companies believe combining the two approaches can address some of the limitations associated with relying on a single surveillance method. Surface sampling provides detailed information about specific locations, while wastewater monitoring can provide a broader building-level perspective.
The partnership also brings global and regional biological threat information into the monitoring framework. This additional context could help healthcare teams assess whether a detected organism represents an isolated finding or forms part of a wider trend.
For hospital operators, the practical value will depend on how effectively these signals can be translated into decisions. Surveillance alone does not prevent infections. Its potential benefit comes from giving infection prevention and control teams information early enough to investigate an emerging risk and introduce appropriate measures.
Earlier Warnings Could Strengthen Infection Prevention
The collaboration reflects a broader shift in healthcare infection surveillance toward environmental monitoring and earlier detection. Hospitals traditionally rely heavily on clinical testing, laboratory results and reported infections to understand their disease burden. Those measures remain essential, but environmental surveillance can potentially identify warning signs before infections become visible through conventional clinical pathways.
This distinction is particularly relevant for healthcare-associated infections, where transmission can occur across shared spaces, equipment and hospital infrastructure. Detecting changes in the environment may give infection control teams another opportunity to investigate possible sources and transmission pathways.
The programme could also have implications for antimicrobial resistance monitoring. Perimeter’s wastewater sequencing platform is designed to track resistance genes alongside pathogens. Identifying changes in resistance patterns at the facility level could provide additional information for infection prevention teams and antimicrobial stewardship programmes.
However, the effectiveness of such systems will depend on several factors, including sampling frequency, accuracy, turnaround time and the ability of hospitals to integrate surveillance findings into established workflows. Healthcare institutions will also need clear protocols for deciding when an environmental signal warrants further investigation or intervention.
The partnership between Perimeter and Culturewell therefore represents more than the combination of two monitoring technologies. It is an attempt to connect room-level evidence with building-level surveillance and external biological intelligence within a single infection risk picture.
For hospitals under pressure to improve infection prevention while managing limited resources, earlier and more precise information could be valuable. If environmental signals can consistently provide meaningful warnings before infections become established, hospitals may be able to investigate risks sooner and direct infection prevention resources toward the areas that require attention.
The companies have positioned the programme as a way to strengthen the evidence available to healthcare institutions rather than replace existing clinical surveillance. Its longer-term impact will depend on real-world adoption and whether hospitals can demonstrate that combining multiple environmental monitoring layers leads to earlier interventions and fewer healthcare-associated infections.
As healthcare systems continue to look for more proactive approaches to infection prevention, the Perimeter and Culturewell collaboration highlights an emerging model in which hospital surfaces, wastewater and wider biological intelligence are monitored together. For hospital acquired infection control, that shift could eventually move surveillance from a largely reactive process toward one focused more heavily on identifying and addressing risks before they become clinical outbreaks.
