title: Anaesthesia workforce in Australia and New Zealand.
abstract: A survey of anaesthetic workforce was undertaken in departments in Australia and New Zealand approved for specialist training by the Australian and New Zealand College of Anaesthetists. When compared to a previous survey 17 years before, the results showed that the number of anaesthetics administered rose, the number of operating theatres (OTs) remained the same, but the surgical beds were reduced. There was a small increase (20%) in full-time specialists with a number of vacancies in establishment. There was, however, a large increase (80%) in Visiting Medical Officer (VMO) sessions and a 40% increase in Registrar positions. At the same time there were very large increases in Recovery Romm nurses (125%) and Anaesthetic Assistants (100%). From this survey and other recent government workforce reports it is possible to derive certain workforce postulates--a specialist anaesthetist will on average anaesthetize approximately 1000 patients per annum, one in every nine people in the population will have an anaesthetic each year, and the working lifespan of a specialist anaesthetist is 30 years with 5% working half-time or less. All of this suggests that the correct Anaesthetists to Population Ratio (APR) should be reset to 1:8,500 for both Australia and New Zealand. The number of trainees required to supply a steady state replacement for this specialist workforce is also derived and the current number of training positions is shown to be in excess of these requirements. When the current shortfall in specialist anaesthetists is corrected there will need to be a gradual reduction (by approximately 40%) in the number of training positions to prevent an oversupply of anaesthetists. The factors which may potentially alter this forecast are addressed and include: change in the general population; ageing of the population; change in the average number of anaesthetics administered per anaesthetist per year; alteration in anaesthetists' working lifespan; change in the age distribution of anaesthetists; increased economic usage of operating theatres and changes in the number of College approved training positions.
