What we do

  1. Improved standards of training for Bronchoscopy in the ICU through qualitative and cohort research; using Augmented reality and artificial intelligence.
  2. Evaluate the role of developments in single-use bronchoscopy in ICU.
    - For evaluation of Rapid Diagnostic markers of respiratory infection
    - Improved diagnosis of Burns inhalation injury – to create a searchable library of reference images for any user, and study accuracy for scales of severity.
  3. Utility of new Infection Rapid diagnostic point of care tests (POCT) in critically ill patients
    - PCR-POCT test v standard care to improve antibiotic stewardship for Ventilator-associated pneumonia
    - Cognitive-behavioural factors that influence the value of POCT tests in trying to improve antibiotic stewardship
  4. Treatments for restoring the immunosuppression of critical illness and reducing secondary infection.
    - Can Interferon gamma reduce secondary infection in critically illness?
  5. TASTE-ICU - Development of a safe dissolvable oral taste application for patients nil by mouth, and assessing its role in rehabilitation potential.
  6. The utility of visual quantification of the microcirculation by a hand held CYTOCAM camera, in prognostication of patients in Cardiogenic shock.

Why it is important

  1. Our research and international Bronchoscopy courses (BRIC) suggest that trainees and consultants in ICU feel that instruction and opportunity in this important procedural skill, and competencies around it can be much improved.
  2. The Bronchoscopy in Intensive Care one day courses (BRIC) provide a combination of knowledge, skills and competency simulation training that have received high satisfaction.
  3. Use of bronchoscopy to sample the endobronchial lung and utilise rapid diagnostic platforms (Cytokine-, PCR-, metagenomic-based) for diagnostic accuracy of infection and antibiotic stewardship.
  4. Infection identifying rapid diagnostic tests need to find their place in clinical ICU medicine. More research into prescribing behaviour is important in establishing their utility.
  5. Burns inhalation injury increases mortality in Burns victims. But diagnostic accuracy of severity by bronchoscopy is uncertain, and so are prognostic implications. We are undertaking research into bronchoscopic images, meta-analysis of grading studies, and developing an image repository to test grading reliability.
  6. TASTE-ICU -This is a relatively neglected aspect of sensory deprivation in recovering ICU patients, mainly due to unsafe swallowing. Many patients crave taste but there is no current solution except for thirst. We are developing a potential application for clinical testing and impact.
  7. Microcirculatory visualisation. This is a neglected part of the assessment of haemodynamics in Shock. New technology allows its evaluation against conventional measurement tools of the microcirculation (i.e. Echo, Cardiac output monitoring).

How it can benefit patients

  1. We are developing an evidence base of the need for improved instruction in and maintenance of skills in Bronchoscopy within the ICU setting. By the prospective data assessment from courses, and use of new technologies (Virtual reality simulation and Augmented reality), we aim to provide better training and tools to record competencies. This will improve patient outcomes by:
    - Increasing the number of trainees able to confidently perform safe and effective bronchoscopy,
    - Offer more patients the opportunity to have a bronchoscopy in the ICU if clinically indicated.
  2. New diagnostic POCT PCR-tests, and behavioural methods should allow better targeted POCT utilisation and so antibiotic stewardship
  3. Improved bronchoscopy diagnostic accuracy of the severity of Burns Inhalation injury will improve prognostic accuracy and allow research into evidence based treatments.
  4. TASTE-ICU - A safe oral application of taste for patients who are nil by mouth may provide pleasure and potentially motivation for rehabilitation.
  5. The microcirculatory CYTOCAM ,if introduced in assessments of Cardiogenic shock on mechanical cardiac support, may better predict recovery, heart transplant or end of life pathways.


Summary of current research

  1. Systematic reviews - A systematic review of the effectiveness of competency based programmes for Bronchoscopy skills training in Intensive Care Unit, Anaesthesia and Surgery. The role of augmented reality in training.
  2. Cross sectional observational studies of Trainees experience of Bronchoscopy in ICU -national, regional survey based research
