Outbreak of on a neonatal intensive care unit: Lessons from a Qatari setting.

BACKGROUND

is a major cause of morbidity and mortality in neonatal intensive care units (NICUs). Robust infection prevention and control is key to reducing risk.

AIMS

We describe lessons learnt from an NICU outbreak of in the main maternity hospital in the country.

METHODS

Cases were identified from clinical samples and active screening. Clinical information was collected from the electronic patient record. Infection prevention and control (IPC) practice observations were made using organisational checklists and unit observations. Microbiological testing was by conventional microbiological methods. Statistical analyses were performed using R program. Associations were assessed using the Mann-Whitney U or Fisher exact test. Isolates were typed by pulsed field gel electrophoresis; gel was analysed in Bionumerics software from Applied Maths, Belgium.

RESULTS

Five cases were identified - one was excluded as maternal acquisition. Typing showed a polyclonal outbreak. Widespread contamination of tap outlets of handwashing sinks in clinical areas was found. Main contributing factors were extensive misuse of hand wash sinks for waste disposal, improper sink cleaning, poor hand hygiene compliance and inadequate environmental cleaning.

DISCUSSION

Successful management required a multi-disciplinary approach. All potential water sources and moist environments within and outside the unit were investigated. Interventions successfully addressed the main contributing factors, supported by good communication and robust auditing. With a diverse workforce, the challenge was to ensure housekeeping staff understood handwash sink cleaning procedures; existing training programmes were delivered in multiple languages tailored to the workforce.
