The Westmead Department of Anaesthesia and Perioperative Medicine has a long history of local and collaborative research. It is our mission to perform patient-centred clinical perioperative research. Our research is closely linked to our clinical perioperative practice, which includes patients undergoing diagnostic, interventional, surgical and/or obstetric procedures. It focusses on improving outcomes through reducing complications and improving the patient's experience in their perioperative journey. Our research needs to be of the highest possible quality and will adhere to (inter)national standards and ethical principles.

We aim to engage our clinical staff (both medical and nursing) in our research projects. We actively collaborate with clinicians and researchers within the Western Sydney Local Health District, the Westmead Health Precinct, as well as with regional, national and international partners.

We support our researchers in developing a career that accommodates an optimal combination of clinical care and research, that is sustainable in the long-term. By developing and maintaining a critical mass of clinician-researchers in our department we further build on our academic reputation, and as such improve our attractiveness for excellent clinicians and researchers.

Our department has a full time Research Coordinator and will soon appoint a part-time data-scientist. Regular Research Meetings provide a forum to discuss local research projects and get input from experienced clinician researchers. There are two Audit Supervisors who support trainees achieve their scholar role goals.

Each year, we offer a Research Provisional Fellowship position. This fellowship that has dedicated research time, which makes it a great opportunity to kick-start your own research project and a higher academic degree. For more information on this fellowship, please email A/Prof Stefan Dieleman.
