It would be good to hear your responses to the pro-PA arguments that have been made. Meanwhile, Professor Peter Brooks, director of the Australian Health Workforce Institute, explains below why he believes that Australia needs PAs. (Incidentally, he is also due to speak at at a University of Sydney seminar on May 3 titled Are we training too many doctors?.) Professional self-interest is blocking introducton of physician assistants Peter Brooks writes: Well done Croakey for running these stories on Physician Assistants (PAs). The opposition to the introduction of these health workers mirrors very much what happened in the US some 40 years ago. Strident cries from the American Medical Association that their introduction would end life as we know it. But interestingly it didnt! Why the nurses are so actively against it is interesting but one would have to ask all opposing groups are they interested in opposing for oppositions sake, are they interested in providing health services to patients who currently find it difficult to access them because the workforce is not there, or are they interested in preserving the status quo with siloed health professional practice? The health service and its constituent parts is a very complex organism but every part of it should work together to improve patient care and not work only in the interests of the health professional or have I got that wrong ? The health and social welfare workforce is currently the largest in Australia 1.4 million and like the rest of the population, it is ageing. We will need to recruit about half a million new workers at least to this sector over the next decade a significant challenge that policy makers and politicians do not seem to be fully accepting at present. Where are these new workers to come from? Current recruitment will not achieve these targets so perhaps some innovation is required. Trials of new models of care have been carried out by Queensland Health and the South Australian Health Commission in respect to PAs. These trials, albeit small, did suggest that these new health professionals would be useful across a variety of health care situations.
