5th annual lecture, on innovative systems of trauma care. Mark has had a lifetime's experience as an emergency physician working in what's known as a 'decision-rich' environment, where decisions have to be made rapidly on the basis of often incomplete and certainly dynamic information. Mark heads the Alfred's trauma service and also the joint Alfred-Monash National Trauma Research Centre, and has developed software to assist with that process. Professor Robyn O'Hehir, CCS's Deputy Head of School, MCed the event. The video will be released soon on the CCSMonash youtube channel.
