title: Physician assistants: trialling a new surgical health professional in Australia.
abstract: BACKGROUND
  The Australia health workforce productivity Commission Research Report in 2005 identified workforce shortages. One of the recommendations is that new models of health care be established. As a result South Australia is trialling United States trained physician assistants in a pilot program. This paper summaries the review of literature of the physician assistant role and safety in the surgical setting.
  
  
  METHODS
  A literature search using Medline and Pubmed from 1966 until 2009 with key words: physician assistants, midlevel providers, surgery. The references of the results were also searched for suitable articles. The Google search engine was also used with the above keywords to search for latest developments from nontraditional sources.
  
  
  RESULTS
  There were over 200 suitable articles relating to the quality and safety of physician assistants. The overwhelming majority of the articles originate from the United States and these vary in quality. There were 13 published studies identified that documented physician assistants in the surgical setting.
  
  
  CONCLUSIONS
  From the published data physician assistants have been shown to provide safe and provide high quality care in surgical units. It is important that prior to their commencement their role is defined to alleviate conflict and confusion in the team. Continued auditing should be conducted to monitor progress and impact.
