CRE in ICU at a Regional Hospital Airofog U260 ULV with Chemgene HLD4H Stopped the Outbreak in 21 Days

The Morning the Antibiogram Hit Dr Nueng's Desk

A Class-A regional hospital in north-east Thailand has a 12-bed ICU receiving critical patients from every district. One Wednesday, Dr Nueng — head of Infection Control — saw three positive cultures: Carbapenem-Resistant Enterobacteriaceae (CRE) in all three.

CRE is "resistant to nearly everything" with a 50% mortality rate. The 78-year-old patient in Bed 4 died the same evening. A full ICU spread would force a temporary shutdown and patient transfers to other provinces.

HAI: the Infection You Catch in Hospital

Healthcare-Associated Infections include MRSA, VRE, CRE, Acinetobacter baumannii, Clostridium difficile, Pseudomonas aeruginosa.

They spread via high-touch surfaces — bed rails, monitor cables, ventilator parts, catheter caps, door handles, nurses' hands — and survive 5–7 days to a month on dry surfaces.

WHO and JCI standards require terminal disinfection after every patient transfer plus daily environmental disinfection above general standards.

What HAI Costs a Hospital

1. Higher mortality damages reputation.
2. 8–15 extra hospital days × 12 beds = millions in added cost.
3. Lawsuits from bereaved families.
4. JCI / HA reaccreditation scores fall.
5. Temporary ward closure forces province-wide patient transfers.

Why Standard Hospital Cleaning Isn't Enough

Manual wipe-and-clean: covers visible surfaces only; misses airborne load and equipment crevices.

UV-C robots: excellent but THB 1.5–3 M, one room at a time, equipment must be moved out.

Pump sprayers: wet, no ceiling coverage.

The IC team needed U260 fogging Chemgene HLD4H during ICU terminal cleaning or between shifts — killing airborne and surface organisms simultaneously.

U260 + Chemgene HLD4H — the New IC Standard

Dr Nueng worked with WHD to validate U260 + Chemgene HLD4H in the ICU, swabbing 50 high-touch points before and after fogging.

Protocol: 1) Move patient to standby room. 2) U260 fogs 24 m² with Chemgene HLD4H in 3 minutes. 3) Room closed 30 minutes. 4) Ventilate 15 minutes. 5) Housekeeping wipes patient-contact surfaces. 6) Patient returns.

Results: 99.997% reduction at every swab site, CRE cleared in 21 days, overall HAI rate down 65% the following quarter.

Why Chemgene HLD4H Fits U260

Chemgene HLD4H meets EN 14476, EN 14348, EN 13727, EN 13624 — effective against enveloped viruses (Coronavirus, Influenza), non-enveloped (Norovirus, Polio), resistant bacteria (MRSA, VRE, CRE), fungi (Candida), and TB.

U260's 5–50 micron droplets distribute the disinfectant across IV lines, monitors, ventilators, bed frames, and curtains — leaving a continuously biocidal film.

Before vs After — Class-A Hospital

Before: 3 CRE positives, 1 death, millions in added cost.

After (21 days): Every bed swab zero CRE, HAI rate −65%, JCI Gold-pass reaccreditation.

Dr Nueng — Head of Infection Control

"We already ran the best wipe-and-clean in the country and still saw HAI. Adding U260 + Chemgene dropped our HAI rate by 65% — and gave our nurses more time at the bedside."

— Dr Nueng, Head of Infection Control, regional hospital
