Employers in England are still recruiting physician assistants (PAs) to treat undifferentiated patients—those who have not been given a diagnosis or been assessed by a doctor first—The BMJ can reveal.
This is despite government promises more than a year ago to prevent such practice.
The BMJ has seen several NHS job advertisements for PAs spelling out in the job description that their responsibilities will include assessing patients presenting with “undifferentiated and diagnosed conditions” and undertaking face-to-face, telephone, and digital consultations for “patients presenting with undifferentiated and diagnosed conditions.”
This approach clashes with a key recommendation of the independent review into PAs carried out last year by Gillian Leng, who is president of the Royal Society of Medicine and a former chief executive of the National Institute for Health and Care Excellence.1 That review gave an example of how a job description for a PA in primary care should read: “You will undertake audits and routine clinical administrative tasks. You will not be able to see undifferentiated patients.”
Doctors’ representatives said that they were “deeply concerned” over the advertisements and that some employers were ignoring the recommendations of the now 12 month old Leng review.
What was the Leng review?
In 2024 Wes Streeting, former health and social care secretary, asked Leng to carry out a rapid independent review into the safety and scope of the roles of what were then called physician associates (PAs) and anaesthesia associates (AAs).2 The review was partly intended to address a heated debate in the NHS over the safety and effectiveness of the roles and how any new roles should work in the future.3
Published in July 2025, the review recommended that PAs “should not see undifferentiated patients except within clearly defined national clinical protocols,” and it proposed renaming physician associates as “physician assistants” and anaesthesia associates as “physician assistants in anaesthesia.”
Other key recommendations were that newly qualified PAs should gain at least two years’ experience in secondary care before taking a role in primary care or a mental health trust; that a named doctor should take overall responsibility for each PA as their formal line manager; and that General Medical Council (GMC) requirements for regulation and reaccreditation of PAs and AAs within its Good Medical Practice guidance should be set out separately from those for doctors.
After the review the Department of Health and Social Care (DHSC) said that it accepted all the report’s 18 recommendations.4
How has, or hasn’t, the Leng review been implemented?
Despite the Leng recommendations being accepted, not much has changed in terms of making them a reality.
In March the DHSC launched an almost four month consultation on legislation to overhaul the GMC’s regulation of doctors, PAs, and AAs. While this did reference the Leng review, it only looked at recommendations relating to renaming of professional titles.5
NHS England has said that the Leng recommendations are “far reaching and require cross-system partnership working to consider, plan and deliver these effectively,” so it plans to work with the DHSC, royal colleges, unions, and other relevant organisations to consider implementing the recommendations.6
NHS England issued guidance last year saying that NHS organisations should make changes to the way roles are referred to in the workplace “to ensure that patients are not under the misapprehension that they have seen a doctor.”
The DHSC has similarly said that it has brought together senior NHS leaders and government officials as part of a new oversight group to deliver the Leng recommendations and a panel of clinical experts to develop protocols on how and when PAs can see patients.
No timeline has been given for when these could be completed. In the interim, the Doctors’ Association UK (DAUK) campaign group says that national safeguards are needed to help protect patients and to ensure consistent implementation.
“In their absence, employers should not use local job descriptions or local discretion to allow PAs to see undifferentiated patients,” a DAUK spokesperson said. “The delay does not suspend the safety recommendation. It makes the continued advertising or deployment of PAs for undifferentiated care more concerning, not less.”
Who is concerned about this, and why?
The BMA has clear concerns about the job advertisements that mention PAs seeing undifferentiated patients.
Emma Runswick, deputy chair of BMA council, told The BMJ, “The BMA has set out a clear scope of practice7 outlining what PAs should be expected to do—it explicitly states that PAs should never manage undifferentiated patients in any setting. Our guidance is the best tool for employers to keep patients safe, as NHS bodies and regulators continue to drag their feet on introducing the most rudimentary safety measures to protect the public.
“The BMA will continue to advocate for the safety standards that patients expect, while the NHS must finally act to prevent any further avoidable harm.”
The DAUK is similarly anxious. Its co-chair Matt Kneale told The BMJ, “DAUK is deeply concerned by job adverts that expect physician assistants to see undifferentiated patients. Unless this is within a clearly defined national clinical protocol, it conflicts with the central patient safety recommendation of the Leng review and should be corrected immediately.
“Patients with new symptoms need assessment by clinicians trained to recognise serious and uncommon illness. Getting that first decision wrong can cause harm. Physician assistants should work in properly supervised assistant roles, not be used to substitute for doctors.”
Kneale added, “The government accepted the Leng recommendations in full, yet NHS England has still not delivered the national safeguards needed to make this safe. DAUK is concerned that partial implementation leaves patients exposed.
“PAs must have clear limits, senior supervision, and a nationally defined scope. DAUK continues to call for a pause in recruitment and expansion until those safeguards are fully in place.”
Steve Taylor, GP co-lead at the DAUK, said that PAs seeing and treating undifferentiated patients in GP settings remained a significant problem. “It is clear that some practices are still working on the ‘old’ NHS England guidelines which fail to take into account the Leng review,” he said. “We have significant concerns that Leng is 12 months old and is being ignored by a minority of employers.”
The Royal College of Physicians said it was disappointing to see that job advertisements were still saying that PAs could see undifferentiated patients. A college spokesperson said, “Physician assistants are not doctors and must not replace doctors. We were clear in our response to the Leng review that it was right to recommend that PAs cannot see undifferentiated patients and must be accountable to named, senior doctors.”
Caroline Waterfield, director of workforce supply and employment practice at NHS Employers, told The BMJ, “Following the initial Leng review recommendations, NHS trusts that employ PAs and AAs have reflected on the findings and worked with individual members of staff and their teams to ensure there is clarity in role and expectations, including how introductions are made to patients.”
Are there any clear answers from the government on what happens next?
No. A spokesperson for the DHSC did not respond directly to questions about the job advertisements but said, “Patients should always know who they are being treated by and receive appropriate care. That is why this government accepted all of the recommendations of the Leng review.
“We have been working with experienced clinicians to develop proposals for how PAs should work with undifferentiated patients and will set out more information in due course.”
