Centre for Surgical Evidence Assessment and Training (SEAT)


Welcome to the SEAT Centre – The centre of Surgical Evidence, Assessment and Training

This Centre was established in 2009 and is a designated surgical research centre of the Queen Elizabeth Hospital. The primary focus of this centre is to develop effective and safe surgical interventions, adequately evaluate them and then deliver them to the population, not only in Australia but ultimately worldwide.


For new technology to be safely introduced in to our health systems, appropriate evaluation and assessment needs to occur, combined with effective training programmes devised for the surgical teams. Such a system is necessary for all new surgical advances, however it is often lacking in our healthcare systems.


This centre will initially join together two clinical sites, the Queen Elizabeth Hospital and the Royal Adelaide Hospital, as major laboratories for the surgical trials and post-graduate teaching programmes that need to be developed in order to introduce new surgical practice.




The role of the centre is to develop a monitored and continuous process to ensure that the following four stages are sequentially addressed.


Stage 1 is that of device development and technique development building on existing technologies, refining them, adapting them, and then developing them to the stage where they require clinical evaluation.


Stage 2 is surgical clinical trials. This is focussed on using the various surgical operations in an environment which enables assessment of safety, efficacy and cost so that it is possible to provide information to practitioners, patients, hospitals and governments as to the likely value and outcomes associated with each new surgical technologies.


Stage 3 will be to harness the existing surgical evidence that exists for new techniques, technologies and approaches in surgery and provide an evidence based framework on which decisions can be made, either at the early inception of the technology or as the technology develops and matures over time.


Stage 4 of the introduction of new surgical techniques, technologies and approaches is developing valid training and curricula. Without appropriate training, the skills required to gain the surgical outcomes possible cannot be achieved. To this end the harnessing of techniques of simulation, curriculum development and training environments need to be utilised in a way that enables the practice of surgery to be disseminated in a reliable, reproducible and verifiable form.


For example, if a new device is being evaluated at stage 1 and it is deemed successful, this will lead to a large clinical trial of the technology at The Queen Elizabeth Hospital and the Royal Adelaide Hospital (Stage 2) in order to gain enough participants for significant statistical analysis. Once its success has been determined via the clinical trial, it will again be confirmed using an evidence based approach (Stage 3), and then introduced in to practice (Stage 4).
