Physician associates and the scope-of-practice row

This topic separates candidates faster than almost any other, because it is easy to have a feeling about and hard to have a position on. The feeling usually arrives pre-formed from social media: either that physician associates are being handed work they are not trained for, or that doctors are defending their territory. Both of those are arguments about people. The panel is listening for an argument about systems.

Here is the version worth holding. A role introduced without a regulator, without a nationally defined scope and without an agreed supervision model will drift, because individual employers will each answer those questions differently. That drift is the story. It explains why the same job title can mean one thing in a large teaching hospital and something quite different in an under-staffed general practice, and it explains why the fix being attempted is regulatory rather than personal.

Physician associates were introduced into the NHS in the early 2000s, adapted from a longer-established American model. The route in is a science degree followed by an intensive two-year postgraduate course built around general medicine, with placements across specialties. Graduates take a national examination and, since December 2024, register with the General Medical Council.

What they do varies by setting: taking histories, examining patients, ordering and interpreting some investigations, and managing patients within an agreed range alongside a supervising doctor. What they cannot do is fixed by law and by the limits of the qualification. As of 2026 they have no prescribing rights and cannot request ionising radiation, and every physician associate works under the responsibility of a named supervising doctor rather than independently.

The sequence matters more than any single moment in it, because the criticism that landed hardest was not about what physician associates did. It was about the twenty years in which nobody had defined what they should do.

An answer that only argues one way is easy to dismantle, and panels dismantle it for sport. Hold both of these at once.

The case for the role. Medicine has always been delivered by teams, and a team of identically trained people is a team that wastes most of its training. A physician associate who stays with one department for years accumulates a depth of local knowledge that rotating junior doctors cannot, and continuity of that kind has real value. Expanding the number of doctors is also slow: a student starting medical school now is a consultant in the second half of the 2030s, which is why every workforce plan reaches for roles that can be trained faster.

The case against how it was done. None of that answers the question the role was launched without: what, precisely, is this person qualified to decide alone? Undifferentiated patients are the hardest work in medicine, not the easiest, because the diagnosis is not yet known and the skill is in recognising the presentation that does not fit. Deploying a two-year qualification against that, with supervision defined locally rather than nationally, put the risk in exactly the wrong place. And where a patient does not know which profession they are seeing, informed consent is already thin.

This arrives in three shapes. The direct one: "What is a physician associate?" The opinion one: "Should physician associates be able to prescribe?" And the disguised one, where the role is never named but the answer needs it — "How would you feel about working in a multidisciplinary team?" or "What are the biggest challenges facing the medical workforce?"

For the direct question, define the role and its limits, then date the regulation. For the opinion question, give the structural answer before the personal one. For the disguised question, use the role as your worked example of what makes delegation safe.

Start with the regulator: the GMC pages on physician associate and anaesthesia associate regulation are short and tell you exactly what the register does. Then read a summary of the Leng review recommendations rather than the coverage of them. If you want the argument in the profession’s own words, the BMA and the Royal College of Physicians both publish their positions, and reading the two together is more useful than reading either alone.

Two pieces here give you the surrounding system. How a doctor is actually trained is the comparison the whole argument rests on, and the workforce dispute explains the staffing pressure that made skill mix policy in the first place. For the wider team, our guide to the multidisciplinary team puts the role in context.
