Results at a Glance
Following the introduction of NEX:
CRE screening compliance increased from 17.1% to 22.8%.
This represents a 5.7 percentage-point increase and a 33.3% relative improvement.
Cases without a recorded response fell from 49% to approximately 40%.
This represents an approximately 18% relative reduction in cases without a documented action.
Results Presented by Our Hospital Partner
The Infection Prevention and Control team at Phramongkutklao Hospital presented results from its use of NEX at Thailand’s 23rd National Seminar on Infection Control.
Held in Chonburi in June 2026, the national conference brought together healthcare professionals from across Thailand to share practical approaches to current Infection Prevention and Control challenges.
The hospital team presented how automated alerts and shared workflow tracking were being used to support the management of carbapenem-resistant Enterobacterales and improve follow-up screening.

The Challenge of Consistent CRE Screening
Carbapenem-resistant Enterobacterales (CRE) are difficult-to-treat bacteria that can spread between patients and healthcare facilities.
Figure 2. Enterobacterales are a group of bacteria (germs) that are a normal part of the human and animal gut but can also cause infections. Carbapenem-resistant Enterobacterales (CRE) are germs resistant to one or several antibiotics called carbapenems.
Patients may carry CRE without displaying symptoms. Screening can help hospitals identify this hidden colonisation, introduce appropriate precautions and reduce the risk of onward transmission.
However, maintaining screening compliance across a large hospital is operationally difficult.
Recommended screening may be missed when:
Patient risk changes during an admission.
A patient moves between wards.
Follow-up screening becomes due.
Responsibility for an action moves between teams.
Information is held across different systems.
An outstanding request is not visible to the right person.
The challenge is often not a lack of guidance. It is ensuring that the right action is identified, communicated and followed through consistently.
Supporting the Workflow with NEX
NEX gives the hospital’s Infection Control team a shared view of patients requiring review, screening or another infection-control action.
The system brings together microbiology results, infection status, patient movements and local screening rules to help teams identify where an action may be outstanding.
The workflow supports the team through:
Automated Alerts. NEX identifies patients who meet locally configured criteria for CRE screening or follow-up and brings them to the team’s attention.
Shared Action Tracking. Outstanding actions can be reviewed through a shared workflow rather than being managed through separate spreadsheets or individual handovers.
Clearer Patient Status. Teams can see relevant microbiology history, current infection status and previous actions in one place.
Follow-Up Visibility. Cases without a documented response remain visible, helping the Infection Control team identify missed steps and follow them up.
NEX does not make screening or isolation decisions automatically. It supports the hospital team by showing where review may be needed and whether an agreed action has been recorded.
Improved Screening Compliance
Following deployment, documented CRE screening compliance increased from 17.1% to 22.8% representing a 33.3% improvement relative to the previous compliance rate.
The proportion of eligible cases without a recorded response also fell from 49% to approximately 40%. This represents a reduction of around nine percentage points, or approximately 18% relative to the original level.
Together, these results suggest that automated alerts and shared workflow tracking helped the team identify more outstanding screening actions and improve the consistency of its response.
What the Results Mean
This was an operational before-and-after evaluation, so the results should not be interpreted as proving that NEX alone caused the improvement.
Screening compliance can also be influenced by staff engagement, local leadership, training, workload and changes in clinical practice.
However, the findings provide encouraging real-world evidence that connected alerts and shared workflow tracking can support more consistent CRE management.
They also show that the value of infection technology is not limited to predicting risk. Practical improvements in communication, visibility and follow-through can change how reliably existing infection-control policies are applied.
Next Steps
NEX and the hospital team will continue monitoring the workflow and examining where further improvements can be made.
Future evaluation will consider:
Time from screening eligibility to action.
The number of missed or delayed screens.
Differences in compliance between wards.
Staff time required to identify and follow up outstanding actions.
The relationship between screening compliance, ward exposure and CRE transmission.
Whether alerts can be refined to prioritise the highest-risk cases.
The objective is to help Infection Prevention and Control teams move beyond identifying what should happen towards making sure that it does.
