Whither medicine? The expansion of non-doctor practice

To the Editor: In his recent editorial,1 Van Der Weyden laments the “displacement” of doctors in modern health care by nurse practitioners and physician assistants, and bemoans the fact that discussion and debate about these matters is largely confined to medical tabloids such as Australian Doctor.

In this context, the editorial cites unsubstantiated and inflammatory comments from Australian Doctor correspondents claiming that nurse practitioners place patients at risk.2,3 Remarks that nurse practitioners are “a disaster unfolding” and “people will die”3 are not only inflammatory but also inaccurate. Medical and nursing insiders have made these claims with self-appointed legitimacy and without evidence. They demonstrate a surprising level of ignorance about the role of nurse practitioners and the evidence base that supports their practice, particularly in emergency care.4 In an era where the drum of quality and safety in health care and evidence-based practice beats the loudest, where is the evidence to support such claims? Perhaps the lack of evidence is the reason why such claims implying that nurse practitioners present a risk to patients are housed in medical tabloids, where they escape the rigorous scrutiny of peer review that would otherwise expose this deficit.

Van Der Weyden bewails that nurse practitioners are the only health professionals “whose skills and talents are extolled”.1 We doubt whether such trivialities are at the forefront of the minds of emergency nurse practitioners, who comprise a large proportion of nurse practitioners in Australia. As part of the broader health care team, their focus — and the focus of their physician, nurse and allied health colleagues — would be on the immediate and ongoing needs of their patients.

Van Der Weyden asserts that an assumption of the equivalence of nurses and physicians underpins the political and industrial agenda for “doctor displacement” in general practice in Australia. Such an assertion is entirely moot. High-quality and safe health care cannot be realised by a monopoly of nurses, or physicians, or any other health profession. Nurses and physicians are only two of the many threads in the tapestry of high-quality, safe and evidence-based health care. Their success lies in symbiotic mutualism, not commensalism, amensalism, or parasitism. And, just like in tapestry, pulling any one thread from the fabric renders the picture incomplete.5

Unless there is substantial evidence to the contrary, bringing the safety of nurse practitioners into question is senseless, particularly given the well deserved support they have from their peers in the wider health community and their patients, both in Australia and overseas.
