Fellowship Project: The development of a model to direct clinical decision making in airway management in patients with spinal cord injury

Aims: The aims of this project were to develop an algorithm to assist clinicians to decide whether patients were able to breathe for themselves or whether they required an artificial tube for assistance to breathe and cough.

Methods: The airway management of all patients suffering an acute cervical spinal cord injury in Victoria between January 2005 and August 2009 has been recorded. The factors that clinicians identified were the most influential in their clinical decision making process regarding airway management was also recorded. This data was then analysed to identify the most important factors that predicted whether a patient was able to breathe on their own or whether they received an artificial tube called a tracheostomy.

Results: In Victoria patients who are admitted to the intensive care unit following cervical spinal cord injury are less likely to require a tracheostomy to allow them to cough effectively compared to elsewhere in the world. The lung volume, the amount of oxygen in the blood and the amount phlegm in the lungs were best able to predict who was able to breathe on their own and who would require a tracheostomy.

Conclusions: The results of this study demonstrate that it is possible to predict patients who may be able to breathe on their own and those that will require a tracheostomy based on 3 simple clinical assessments.

Career Development: Sue participated in the following activities funded during the course of her TAC Fellowship:

Short Courses:  Seminar on Muscle Mass, Professor Mary Galea, The University of Melbourne

Knowledge Translation:  The algorithm developed in the course of the fellowship has important clinical implications for guidelines and teaching tools in the intensive care unit environment. It is the first attempt to provide clinicians with an evidence based decision regarding airway management in the cervical spinal injury population. Post Fellowship Career Development: Sue is well on her way to completing her PhD and will present her findings at upcoming spinal cord conferences; she has already published several articles on her fellowship research.

She plans to continue this area of research, specifically validating the preliminary classification and regression tree model of clinical decision making using an independent data set from an ICU of another specialist spinal centre. This validation is required to either confirm or prune the model prior to implementing into clinical practice.

Feedback on the Fellowship from Sue Berney:

“This fellowship has been invaluable to me in allowing me to complete the first draft of my thesis almost 12 months ahead of time. The relief from clinical responsibilities has allowed me to concentrate on the research process and I feel I have gained much more out of my PhD that I otherwise might have and subsequently have enjoyed the experience. In addition I have been able to write papers throughout my PhD which means the publications are current and will assist in developing my reputation in the area of research in spinal cord injury. This would not have been possible without the support of the fellowship. This fellowship has been a very positive experience for me.”
