Study type
Interventional
Description of intervention(s) / exposure
Intervention group: All patients admitted to the ICU during this time period will undergo active screening with rapid molecular detection of MRSA on admission to, discharge from and twice weekly during the ICU stay. Patients found to be colonised with MRSA will be isolated in a single room (or cohorted with other MRSA colonised patients). Contact precautions (gloves and gowns for all contacts) will also be used for MRSA colonised patients. These precautions will be used for the duration of the patient's ICU stay once found to be colonised. Patients not found to be colonised will be managed using the same infection control precautions as in the control period (ie standard precautions and plastic aprons for all patients).

Other interventions
Comparator / control treatment
Control group: usual practice ie use of Standard Precautions (including wearing plastic aprons for all contacts) for patients regardless of MRSA colonisation status. These precautions will be used for the duration of the patient's stay in the intensive care unit (ICU). Other infection control precautions will be used as indicated for other conditions.
Control group
Historical

Outcomes
Primary outcome [1] 2779 0
Acquisition of MRSA at any time during ICU admission. Patients will required documented evidence of negative screening swabs and then subsequent MRSA positive screening swabs or clinical isolates to be defined as an MRSA acquisition.
Timepoint [1] 2779 0
Results of swabs will be monitored daily.
Secondary outcome [1] 4690 0
Proportion of patients with new clinical isolate of MRSA.
Timepoint [1] 4690 0
At any time during ICU admission and for 48 hours after ICU discharge.
Secondary outcome [2] 4691 0
Results of swabs.
Timepoint [2] 4691 0
Will be monitored daily
Secondary outcome [3] 4692 0
Patients who have had MRSA colonisation in the ICU.
Timepoint [3] 4692 0
Will be monitored for development of clinical infection up to the time of hospital discharge
