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.

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

Summary
Brief summary
MRSA is a significant problem for hospital patients, causing increased length of stay and risk of complications. It is spread mainly on the contaminated hands of healthcare workers. Control of MRSA within hospitals still remains controversial, with some insisting that swabbing of all patients and use of special isolation precautions is mandatory for prevention of its spread. We plan to test whether swabbing all patients admitted to the intensive care unit and then putting patients who are found to be positive in single rooms and using gloves and gowns for all contact with these patients is more effective at preventing spread of MRSA from patient to patient than what we currently do ie looking after patients in the general ward, wearing plastic aprons at all times and only using gowns and gloves if we are likely to come into contact with bodily fluids (and not swabbing any patients). We plan to use the most rapid tests available to determine whether someone is carrying MRSA on their body which will give us a result within hours compared with the 2-3 days it currently takes to get a result. We also plan to do an economic evaluation to see if the intervention is worth the extra cost.
