The potential for transmission of infection must be assessed at the patient’s entry to the care area.  If hospitalised or in a care home setting this should be continuously reviewed throughout the stay/period of care. The assessment should influence placement decisions in accordance with clinical/care need(s).

Patients who may present a cross-infection risk in any setting includes but is not limited to those:

• with symptoms such as loose stools or diarrhoea, vomiting, fever or respiratory symptoms. 
• with a known (laboratory confirmed) or suspected infectious pathogen for which appropriate duration of precautions as outlined in A-Z of pathogens are not yet complete
• known or suspected to have been previously positive with a Multi-drug Resistant Organism (MDRO), for example MRSA, CPE
• who have been hospitalised (inpatient) outside Scotland in the last 12 months (including those who received dialysis)

Further information regarding general respiratory screening questions can be found within the resources section of the NIPCM.

Isolation facilities should be prioritised depending on the known/suspected infectious agent (refer to Aide Memoire - Appendix 11).  All patient placement decisions and assessment of infection risk (including isolation requirements) must be clearly documented in the patient notes.

When single-bed rooms are limited, patients who have conditions that facilitate the transmission of infection to other patients (e.g., draining wounds, stool incontinence, uncontained secretions) and those who are at increased risk of acquisition and adverse outcomes resulting from HAI (e.g., immunosuppression, open wounds, invasive devices, anticipated prolonged length of stay, total dependence on HCWs for activities of daily living) should be prioritised for placement in a single-bed room. Single-bed room prioritisation should be reviewed daily and the clinical judgement and expertise of the staff involved in a patient's management and the Infection Prevention and Control Team (IPCT) or Health Protection Team (HPT) should be sought particularly for the application of TBPs e.g. isolation prioritisation when single rooms are in short supply. 

Hospital settings

• Patients who present a cross-infection risk should be isolated in a single room or for patients with a known or suspected pathogen spread by the airborne route, in a specialised negative pressure isolation facility where available.
• Isolation of infectious patients can be in specialised isolation facilities, single room isolation, cohorting of infectious patients where appropriate, ensuring that they are separated by at least 2 metres with the door closed.
• Signage should be used on doors/areas to communicate isolation requirements and prevent entry of unnecessary visitors and non-essential staff.
• Infectious patients should only be transferred to other departments if medically necessary.  If the patient has an infectious agent transmitted by the airborne/droplet route, then if possible/tolerated the patient should wear a surgical face mask during transfer.
• Receiving department/hospital and transporting staff must be aware of the necessary precautions.

Cohorting in hospital settings

Cohorting of patients 

Cohorting of patients should only be considered when single rooms are in short supply and should be undertaken in conjunction with the local IPCT.

Patients who should not be placed in multi bed cohorts:

• patients with different infectious pathogens/strains and patients with unknown infectious pathogens (laboratory confirmation still awaited)
• patients considered more vulnerable to infection
• patients with a known or suspected infectious pathogen spread by the droplet/airborne route who will undergo an AGP
• patients who are unlikely to comply with TBPs

Staff cohorting

Consider assigning a dedicated team of care staff to care for patients in isolation/cohort rooms/areas as an additional infection control measure during outbreaks/incidents. This can only be implemented through planning of staff rotas if there are sufficient levels of staff available to ensure consistency in staff allocation (so as not to have a negative impact on non-affected patients’ care).

Before discontinuing isolation in hospital settings

Individual patient risk factors should be considered, for example there may be prolonged shedding of certain microorganisms in immunocompromised patients). Clinical and molecular tests to show the absence of microorganisms may be considered in the decision to discontinue isolation and can reduce isolation times. The clinical judgement and expertise of the staff involved in a patient’s management and the Infection Prevention and Control Team (IPCT) or Health Protection Team (HPT) should be sought on decisions regarding isolation discontinuation.

Primary care/out-patient settings

• Patients attending these settings with suspected/known infection/colonisation should be prioritised for assessment/treatment, for example scheduled appointments at the start or end of the clinic session. Infectious patients should be separated from other patients whilst awaiting assessment and during care management wherever possible.
• If transfer from a primary care facility to hospital is required, the ambulance service should be informed of the infectious status of the patient.
