About Us

Our organisation

The Society for Education in Dental Anaesthesiology and Traumatic Events (SEDATE) Inc, previously named as The Centre for Resuscitation Education and Simulation Training (CREST) Inc, (ABN 76 527 885 920 ) is an Australian non-for-profit organisation dedicated to improving quality of dental service and patient safety by applying medical simulation to training for oral health clinicians. Our organisation offers interactive courses and education programs, including competency-based training, Anaesthetic Crisis Resource Management (ACRM) and continuous professional development. The program aims to teach a wide array of medical emergency scenarios to dental staff via experiential learning.
SEDATE has been accredited by Dental Board Australia (DBA) / Australian Health Practitioner Regulation Agency (AHPRA) since 2010 to run dental sedation re-endorsement courses for dentists who practise conscious sedation in order to facilitate dental treatment for phobic patients, children and special needs patients. Currently dental sedationists are required to attend annual refresher courses for re-accreditation by DBA for the following twelve months.

Our educational concepts

  • Simplification of course content to facilitate course objectives.
  • Consistency of course content to enable a reduction of instructor variability from the intended course syllabus and current guidelines.
  • Training scenarios should be contextual and be applied practically in a real-world setting.
  • Hands-on practice is needed to enhance skill performance objectives.
  • Debriefing and feedback are critical components of experiential learning and allows participants the opportunity to reflect on their performance, and improve in the future.
  • Assessment ensures both achievement of competence and provides the benchmarks that participants strive toward. Assessment strategies should evaluate competence and promote learning, and must be clear and measurable.
  • Instructor, course and program should be evaluated regularly to promote continuous quality improvement.

Our staff

The facilitator for SEDATE courses has always been a consultant anaesthetist who is competent in providing conscious sedation and anaesthesia, and is also an accredited trainer in anaesthetic simulation and ACRM.
SEDATE has been staffed by experienced sedation specialists and highly qualified educators, all of whom have extensive training both in medical and dental fields, in Advanced Life Support (ALS) with Australian Resuscitation Council (ARC) and in simulation training. Our staff has continuous liaisons and training with the Harvard Medical School and the International Federation of Dental Anesthesiology Societies (IFDAS).

Our Technology

The clinical simulation laboratory at the Faculty of Medicine, Health and Human Sciences uses a bespoke setup of cutting-edge technology to deliver life-like clinical simulations to both students and healthcare professionals. 

The laboratory is fitted with an operating theatre (with lights/pendant and anaesthetic machine), a two-bedded hospital ward, breakout rooms, lecture rooms and kitchen facilities. Simulation activities can be observed from the control room or any of the breakout rooms with world-wide live streaming and recording capabilities for debriefing scenarios.

The Simulation Laboratory is managed by the MD program Clinical Skills Development Coordinator and support staff. It is well equipped with a wide range of simulation manikins, part task trainers, ultrasound machines, emergency trollies and more to suit most clinical training scenarios.

Fully renovated in 2017 as part of the Macquarie MD and Doctor of Physiotherapy programs at Macquarie University, the clinical simulation laboratory provides students with invaluable skills that translate directly to real life situations they may face as clinicians. Doctors in training and other practising healthcare professionals have the opportunity to hone their clinical skills before translating them into practice. The advanced healthcare training delivered here include: the Training in Professionals Skills (TIPS) through the Royal Australasian College of Surgeons; Neuroanaesthesia Simulation – accredited by the Australian and New Zealand College of Anaesthetists to deliver Emergency response Activities; Advanced Trainee Right Heart Catherisation Simulation Seminar supported by Cardiac Society of Australia and New Zealand, and this Dental sedation re-endorsement course accredited by the Dental Board of Australia.
