This Clinical Protocol is intended for use by healthcare professionals within Leeds unless otherwise stated.
For healthcare professionals in other trusts, please ensure that you consult relevant local and national guidance.

Infections That Require Source Isolation on the Neonatal Unit Protocol

This protocol provides information on those babies, or their mothers that are diagnosed with an infection or are identified as colonised with micro-organisms that are easily transmitted to other people and constitute an infection risk to other patients, staff or visitors.

This protocol also specifies the Infection Prevention and Control (IPC) actions that are required when a patient is diagnosed or identified as colonised in the list below.

Aims

  • To prevent and control the spread of communicable infections within the neonatal service
  • To promote a safe environment for all patients and staff within the neonatal service
  • To provide the information required to ensure that IPC measures are applied when babies/parents are found to be colonised by or infected with an Alert Organism* or diagnosed with an Alert Conditions*.
  • To ensure that babies with (alert organisms or conditions) are placed in source isolation if as required.

*Alert organisms and conditions are those that are easily transmitted and constitute an infection risk to other babies, staff or visitors.

Background and indications protocol

A requirement for source isolation may be suggested by a clinical presentation e.g. an alert condition or a microbiological result e.g. isolation of an Alert Organism such as MRSA.

The need to source isolate is based on whether the patient has an infection (Alert Organism or Alert Condition) and how that is transmitted.

Source isolation must be carried out according to the Infection Prevention And Control Policy.

If source isolation is not possible, due to lack of side room/capacity, the matron or nurse in charge will contact the IPCT (in hours) or the clinical site manager and consultant neonatologist. The IPC nurse or clinical site matron will contact the on call consultant microbiologist (out of hours), with the required patient information for a risk assessment to be completed.

The risk assessment is only to be completed in conjunction with the IPC Team (in hours) or consultant microbiologist and neonatologist (out of hours). In exceptional circumsatnces source isolation may not be possible but this decision should be made at the senior level and the baby put into source isolation at the earliest opportunity.

Carbapenem-resistant organisms (CPO)

Carbapenem resistant organisms are rare but are emerging. Their transmission characteristics and pathogenesis resemble those of more sensitive Enterobacteriaceae, but the infections are more difficult to treat. For this reason, it is vital that NHS trusts prevent their spread and introduce the identification and screening of high risk patient groups.  Please refer to Carbapenemase-Producing Organisms (CPO) policy; for flowsheet see appendix A

COMMONLY OCCURING ALERT ORGANISMS AND CONDITIONS REQUIRING SOURCE ISOLATION ON NNU

 

Infection (Alert Organism/ Condition)

Source Isolation Required

Mode of Transmission

Duration of Isolation

Precautions Required

Multiresistant E. coli
ESBL coliform
Multiresistant Pseudomonas
Listeria
Serratiaspp; (if multi-drug resistant, carbapenemase-producing or ESBL producing)

yes

Person to person through direct contact with blood and body secretions from those infected or potentially colonised.

Indirect contact from environmental surfaces, linen and patient care equipment that has been contaminated with infected blood or body fluids.

Duration of admission

Hand Hygiene
PPE- Gloves and Apron
Sharps Bins (Orange & Yellow)
Alginate and linen bags
Clinical infectious waste

NB: Any baby admitted from outside Yorkshire should be put in too source isolation and the CPO (carbapenemase-producing organism) policy followed - see appendix A

MRSA

Meticillin-resistant Staphylococcus aureus

Please refer to LTHT IPC MRSA Policy for Neonates.

Yes

Person to person through direct contact with blood and body secretions from those infected or potentially colonised.

Indirect contact from environmental surfaces, linen and patient shared equipment that has been contaminated with infected blood or body fluids.

N.B. Airborne transmission poses significant risk if isolated in respiratory secretions.

Once course of decolonisation has been completed and there is evidence of 3 negative MRSA screens taken 48hours apart.

Please refer to LTHT IPC MRSA policy for neonates

Hand Hygiene
PPE- Gloves and Apron
Sharps Bins (Orange & Yellow)
Alginate and linen bags
Clinical infectious waste

Any respiratory virus

e.g. RSV, influenza, Rhinovirus etc
Also see Trust Policy Respiratory Viruses

Yes

Direct contact or inhalation of airborne droplets from an infected person, indirect contact with contaminated surfaces.

Incubation is between 12 hours and 5 days; the usual period is on average 48 hours dependant on infectious agent.

Source isolation should commence at the onset of symptoms and time of sampling if symptoms are no longer present isolation can be discontinued 7 days after onset of illness.

N.B. Cohorting of symptomatic patients can be undertaken with consultation of IPC Team.

Group A Streptococcal Infection

Please refer to LTHT IPC Group A Streptococcal Infections guidelines

All cases to be reported;
Please refer to appendix F

Yes

 

Person to person through airborne or direct contact with infective respiratory secretions or contact with body fluids.

Indirectly through contaminated surfaces, linen or patient shared equipment.

Incubation is normally 1-3 days.

Until 24 hrs of  appropriate antimicrobial treatment is completed

In cases of Invasive Group A Strep source isolation may be extended for a longer period. IPC advice should be sought in these cases.

Hand Hygiene
PPE- Gloves and Apron
Sharps Bins (Orange & Yellow)

Staphylococcus capitis

Yes

Direct of indirect contact with contaminated person or object

Once Staph. Capitis  has been isolated the patient should remain in source isolation for the duration of the admission

Maternal infections affecting the infant

Infection (alert organism / condition)

Duration of source isolation

Guideline link

Pulmonary TB

Mother and baby should be isolated until mother has received at least 2 weeks treatment. Infant may require treatment. See policy. Discuss with Chest and Infection Control teams before moving out of isolation.

Infant Exposed to Maternal Tuberculosis Policy

MRSA

To remain in isolation until mother and baby decolonised and negative swabs as per policy.

 

Clostridium difficile

 

Clostridium difficile

Chicken Pox
Varicella Zoster

If mother has been in contact with varicella (Chicken pox)  a week before or a week after delivery she should be kept in isolation for duration of incubation period. The infant should have VZIgG - discuss with virology.

Green Book Varicella Chapter.

CMV
Cytomegalovirus

Mother nor baby require source isolation. Universal precautions only.

 

For all other organisms please refer to the Trust Policy Infections (Alert Organisms And Conditions) That Require Source Isolation and seek advice from Infection Prevention and Control (Extension 28536 or through switchboard out of hours).
