Research Interests
I am currently collecting data assessing the usefulness of various scoring systems in predicting morbidity, as reflected by length of hospital stay, and suitability for "fast-track" care following cardiac surgery. This will be developed into a model allowing accurate prediction of likely Intensive Care bed utilisation in this population.
Various aspects of perioperative coagulation continue to be of interest to me. I am using the thromboelastograph (TEG) to assess hypercoagulability in patients with intracerebral tumor presenting for craniotomy and correlating these measurements to the incidemce of venous thromboembolic disease in the postoperative period as diagnosed clinically or by duplex scanning of leg veins. To continue this investigation, I am using TEG to monitor the response to anticoagulation with low molecular weight heparin in this group.
As part of an audit of the introduction of perioperative TEG monitoring in the cardiac surgery setting, I'll be looking at the economic impact of point-of-care monitoring on blood product usage in addition to establishing a point-of-care coagulation laboratory for the cardiac operating rooms and the cardiac surgery ICU (3200).

These relations have been reported to the health system leadership and, when appropriate, management plans are in place to address potential conflicts.
