I am a senior Emergency Medicine Specialist employed at Christchurch Hospital. I have recently developed advanced strategies for early discharge of chest-pain patients presenting to the Emergency Department who are at low-risk of heart attack; these strategies are being implemented in Christchurch and Queensland. I have received grants and awards for this work including being included on a Global Task-Force. My proposed research programme will incorporate a broad international expert network. It will include the systematic redevelopment, validation, testing in clinical practice, and immediate implementation of new diagnostic strategies and blood tests that will allow faster Emergency Department assessment of possible heart attack.The outcomes will help reduce hospital overcrowding and allow significant savings in hospital bed days and duplication of staff time. It will make a rapid impact on healthcare provision and enhance the researchers' and New Zealand's reputation so that both are sought internationally to collaborate on high quality studies.
