Statement of standard

The risk of ventilator associated pneumonia (VAP) is minimised by systematic application of care bundles.


Rationale

Ventilator associated pneumonia (VAP) may occur in between eight and 50% of ventilated infants (1,2), with a prevalence of up to 37 cases per 1000 ventilator-days (2–8). Criteria used to define VAP vary and affect incidence reporting. Despite formal definition in older infants, a specific definition for newborn infants is lacking. (1)

The risk of nosocomial infection is increased because of immature host defences and frequent invasive procedures. VAP arises when there is bacterial invasion of the pulmonary parenchyma in a patient who receives ventilation for more than 48 hours. (1) VAP arises following colonisation of the aerodigestive tract, aspiration of oral secretions and contaminated equipment. (2) Identification of causative microorganisms is not necessary to establish a diagnosis, but microbiological tests are essential to narrow the spectrum of antibiotic therapy.

Risk factors for VAP include low birth weight, prematurity, prolonged mechanical ventilation, reintubation, frequent endotracheal suctioning, presence of invasive devices, transfusions, inotropic drugs, and a history of bloodstream infection. (4,6,8–14) VAPs are associated with increased mortality, morbidity, prolonged hospital stay, and additional costs. (3,4,6,10,15) Multiple interventions are required to minimise the frequency of VAP. VAP may be reduced by careful attention to care practices. (11,16)

Getting started

Initial steps

For parents and family

  • Parents are verbally informed and educated by healthcare professionals about hand hygiene, nosocomial infections, and intubation.

For healthcare professionals

  • Attend training on screening, documentation, and treatment for VAP.
  • Develop strategies for non-invasive ventilation when appropriate.

For neonatal unit and hospital

  • Develop and implement a unit guideline on screening, documentation, prevention, and treatment for VAP.
  • Develop information material on VAP and prevention using proper hand hygiene for parents.
  • Support healthcare professionals to participate in training on screening, documentation, and treatment for VAP.
  • Develop written protocols for ventilator care and audit compliance.
  • Document and monitor the frequency of VAP.

For health service

  • Develop a national guideline for screening, documentation, prevention, and treatment for VAP.

A care bundle for the prevention of VAP includes:

  • A clear pragmatic definition of neonatal VAP.
  • A unit specific guideline covering ventilation strategy aimed at the use of ventilation strategies to minimise duration of endotracheal intubation.
  • Development of objective criteria for intubation and extubation and use non-invasive respiratory support whenever possible.
  • A daily assessment of readiness for extubation to be recorded in the clinical record.
  • Careful attention to hand hygiene before and after contact with the infant for oral care and handling respiratory equipment and supplies.
  • Procedures for minimising contamination of endotracheal tubes during insertion.
  • Adoption of full sterile precautions for suctioning.
  • Use of closed endotracheal suction devices.
  • Regular oropharyngeal suction before ET manipulation, changing infant position, extubation and reintubation.
  • Head of bed elevated at least 30°.
  • Oral care provided 3-4 hourly.
  • Minimisation of ventilator circuit changes (e.g. only on visible soiling, malfunction).
  • Regular audits of adherence to the protocol.
  • Monitoring and reporting the occurrence of VAP (rate per 1000 ventilator days).
  • Regular training sessions for staff on prevention of VAP care bundle.
