PhD Opportunity - Biomarkers and Motor Vehicle Accident Risk
Developing a new clinical tool to assess fitness to drive in patients with obstructive sleep apnea
Background: Obstructive sleep apnea (OSA) is a common sleep disorder linked with increased daytime sleepiness, impaired driving performance and increased motor vehicle accident risk. However, not all patients are impaired by OSA and identifying which patients are affected is a daily clinical challenge for sleep specialists.
The current gold standard clinical test for daytime sleepiness is the maintenance of wakefulness test (MWT), which assesses the patient’s ability to stay awake in a controlled sleep laboratory soporific environment. The problem with this test is that it is an all-day, labour intensive and expensive test, limiting its utility to only in a small portion of OSA patients where excessive sleepiness is clear or work regulations require the test (professional drivers). Furthermore the MWT is inconsistently related to driving impairment and accident risk in patients with OSA. This leaves most patients with OSA untested in regards to the risk of alertness failure while driving. Previous research by our group has identified some initial promising biomarkers of alertness failure and driving risk in OSA patients. Additional independent validation is now necessary to confirm that our biomarkers can consistently identify OSA patients at high driving risk.
Aim: The main aim of this NHMRC funded project is to validate biomarkers of alertness failure and driving impairment in patients with obstructive sleep apnea (OSA) towards developing a clinically deployable, simplified and cost effect fitness to drive assessment. Specifically this project will
- Test the performance of biomarkers to predict diving impairment in OSA
- Compare performance of biomarkers with MWT to predict driving impairment in OSA
- Explore the utility additional biological (blood and saliva), biomarkers to further improve the prediction of driving impairment in OSA
There is an opportunity to discuss and tailor a PhD projects around these broad aims and themes of this large project.
