We often talk about the Allied Health Assistant workforce as though it represents a single model of work.
Behind the title “Allied Health Assistant”, however, sit two quite different ideas about what an assistant is for. Both have shaped the workforce we have today, both have strengths, and many of the tensions AHAs experience at work arise because we have never fully resolved the difference between them.
Model one: the AHA extends a profession
The first and historically dominant model is profession-led.
In this model, the assistant exists to extend the reach of a particular allied health profession: a physiotherapy assistant supports physiotherapy; an occupational therapy assistant supports occupational therapy; a podiatry assistant supports podiatry.
The work is organised around delegation from a specific profession. Tasks that do not require the full expertise of the allied health professional can be transferred to the assistant, allowing the professional to concentrate on assessment, complex decision-making or more specialised work.
This model has some obvious strengths.
It can provide a clear relationship between the AHA and the profession they support. Training can be closely aligned with the work, delegation and supervision arrangements may be easier to understand, and the AHA can develop deep expertise in a particular area of practice.
But there are also limitations.
The assistant can become defined mainly by the tasks a professional is willing to hand over. Scope may expand or contract depending on the confidence, experience and preferences of individual clinicians. An experienced AHA may find that their capability is repeatedly reassessed every time a new professional joins the service.
Most importantly, this model can reduce the AHA to a “pair of hands” rather than recognising them as a worker with expertise, judgement and a career of their own.
Model two: the AHA follows the patient and the work
The second model starts somewhere different.
Instead of asking, “Which tasks can this profession delegate?”, it asks: “What does this patient or service need, and who is best placed to provide it?”
This approach has led to the development of generic rehabilitation assistants, multidisciplinary AHAs and other roles that work across professional boundaries.
A single AHA may support activities arising from physiotherapy, occupational therapy, speech pathology or other disciplines. In community and home-based services, this can make enormous practical sense.
The patient does not necessarily experience their needs in professional categories.
They may need help practising mobility, preparing food, communicating, managing daily activities and participating in their community. Sending a succession of different workers into someone’s home may be less efficient, less personal and less effective than supporting a skilled worker who can help the person work towards a range of agreed goals.
In this model, the AHA can become what researchers have described as a boundary spanner: someone who connects different professionals, settings and parts of the service.
This may be one of the most under-recognised strengths of the AHA workforce, but this model has risks too.
When AHAs work across disciplines, who owns their development? Who supervises them? How do we recognise the skills they accumulate? How does an experienced AHA take their capability from one employer to another?
Without the right infrastructure, flexibility can quickly become ambiguity.
We have treated this as an either/or choice for too long
The future AHA workforce probably needs both models.
Some AHAs will develop deep expertise within a particular discipline or area of practice. Others will work across professional boundaries, particularly in rehabilitation, aged care, disability, rural services and community-based care.
The real problem is not that one model is right and the other is wrong—the problem is that we have often failed to build the workforce infrastructure needed to support either model properly.
A mature AHA workforce needs:
-
a clear professional identity that is not dependent on a single employer or profession
-
common core capabilities that travel with the worker
-
recognition of additional discipline-specific and context-specific skills
-
consistent approaches to delegation and supervision
-
access to continuing professional development
-
mechanisms for experienced AHAs to demonstrate what they can do
-
genuine career progression.
This is where a national professional association matters.
The role of AHANA is not to make every AHA role identical, it is to make the diversity of AHA roles visible, understandable, and portable.
An AHA working in a rural multidisciplinary service may look very different from an AHA working in a metropolitan physiotherapy department. That does not mean they have nothing in common.
Both need a professional identity, and both need access to development. Both need their experience and capabilities to be recognised, and both need a workforce system that sees them as more than the collection of tasks someone else is prepared to delegate.
Perhaps the question for the future is no longer simply, “What can an AHA do?”
It is:
What kind of workforce are we trying to build — and what do AHAs need in order to become a recognised, skilled and sustainable part of it?
