A hospital-wide study from Hong Kong found that targeted decolonisation was associated with a 23% lower adjusted hazard of MRSA appearing in a later clinical specimen. The result is encouraging, but the operational lesson is just as important: identifying an eligible patient is only the beginning. Hospitals also need reliable systems to start treatment, track completion and follow up when the patient has already left.

Across four hospitals at Imperial College Healthcare NHS Trust, conventional cluster criteria caught only about 1 in 5 of the patient pairs genomic analysis flagged as linked — and 2/3 of the clusters they did raise weren't genomically related. IPC teams may be missing real transmission while chasing connections that aren't there.

A predictive model can perform well and still fail to be useful in practice. For Punyisa (Kiki) Suptasan, Product Designer at NEX Health Intelligence, the challenge is turning infection-risk predictions into information that Infection Prevention and Control teams can understand, interrogate and use within their existing workflows. That question: how do we help teams act earlier while keeping the decision in their hands?—has shaped how Kiki and the wider NEX team approach the product.

Infection Prevention & Control (IPC) in hospitals is not held back by a lack of effort or expertise. It is held back by information that is difficult to reach in time. At the same time, many Healthcare-Associated Infections (HAI) are thought to be preventable - clearly, IPC can come to the rescue! For Chang Ho Yoon, Chief Medical Officer at NEX Health Intelligence, Infection Prevention & Control (IPC) teams are already working their hardest to protect patients - but many of them are frustrated, knowing that they could work smarter if only their work environment would let them. That gap between how hard IPC teams work and how effectively they could work is central to what Chang and the wider NEX team are trying to change.

The pandemic showed the cost of having PPE in the wrong place at the wrong time. Hospitals now need better intelligence about when to escalate precautions and when to stop them.

NEX-supported alerts and shared workflow tracking were associated with a 33.3% relative improvement in infection screening compliance.

A new base for our growing team to build together and support NEX’s work with hospitals across Asia.

The funding will support the next stage of NEX’s growth as we expand into more hospitals and help Infection Prevention and Control teams act earlier.

How the pandemic, a mathematical insight and a shared frustration led to a new approach to infection prevention

Evidence shows that timely surveillance, targeted screening and focused interventions can reduce infections while helping hospitals use limited resources more effectively.

By identifying infection risks earlier, hospitals can target screening, prioritise investigations and focus prevention where it matters most.
