Medicine's core strength is not that doctors know a little bit about everything. It is that we are trained to think across systems, manage uncertainty, recognise risk and diagnose the unexpected.
I recently read a LinkedIn post suggesting that GPs manage a large volume of musculoskeletal conditions despite having relatively limited formal musculoskeletal training.
The point was then used to support expanded prescribing rights for pharmacists, arguing that regulated professionals can safely work within structured protocols.
The post was well intended, but it highlighted a misunderstanding I see repeatedly when scope of practice is discussed.
Many non-medical clinicians look at a medical curriculum and assume that because musculoskeletal medicine, dermatology, cardiology, women’s health or paediatrics are not taught as large standalone subjects for years at a time, doctors receive less training in those areas than other disciplines.
That isn’t how medical education works. Medical training is integrated. It is built around diagnosis.
As someone who came to medicine as a mature-age student, I was struck by the intensity of the learning curve. The volume of anatomy, physiology, biochemistry and pathology covered in the first year alone was extraordinary. Concepts that might be explored over extended periods in other degrees were delivered at a pace that required students not only to learn them but to immediately apply them clinically.
When we learn immunology, we learn rheumatoid arthritis and inflammatory joint disease. When we learn oncology, we learn how metastatic cancer presents as back pain. When we learn infectious diseases, we learn septic arthritis and osteomyelitis. When we learn pharmacology, we don’t simply learn what medication to prescribe; we learn how that medication interacts with multiple organ systems, other drugs, comorbidities and physiological states.

The musculoskeletal system is therefore not confined to an orthopaedic rotation. It appears throughout medicine because patients do not present in neat specialty boxes.
The same applies during clinical training.
We see musculoskeletal presentations in emergency departments, general medicine, orthopaedics, radiology, neurology, paediatrics, rheumatology, women’s health and general practice. More importantly, we learn to distinguish the common presentation from the uncommon but dangerous diagnosis hiding underneath it.
That diagnostic responsibility is often overlooked in scope discussions.
Protocols are valuable. Clinical pathways improve consistency and can support safe care. However, protocols work best when patients fit the protocol.
The challenge in medicine has always been recognising the patient who does not.
A sore shoulder may be a rotator cuff injury. It may also be referred pain from elsewhere. Back pain may be mechanical, but occasionally it is malignancy, infection, inflammatory disease or neurological compromise.
The skill is not simply managing the likely diagnosis. It is recognising when the diagnosis is not what it first appears to be.
That is why I become concerned when discussions about scope focus primarily on tasks rather than diagnostic depth.
Healthcare absolutely needs collaboration. I work with pharmacists, nurses, psychologists, psychiatrists, physiotherapists and allied health professionals every day. Good patient care depends on that collaboration. But collaboration works best when we recognise that different professions bring different strengths.
Medicine’s core strength is not that doctors know a little bit about everything. It is that we are trained over many years to think across systems, manage uncertainty, recognise risk and diagnose the unexpected.
Expanding access to care is an important goal. The question is not whether other health professionals are capable or trustworthy. The question is whether we fully appreciate the depth of diagnostic training that sits behind seemingly simple medical decisions.
That depth is often invisible. But it is one of the most important safety nets in the healthcare system.
