16 July 2025

The Leng Review, published today (16 July) is an independent review of the physician associate (PA) and anaesthesia associate (AA) professions.

Led by Professor Gillian Leng, the review responds to concerns raised around patient safety, role clarity and the expanding presence of these professionals in healthcare settings.

Evidence for the review was gathered via an independent literature review, 8,558 frontline staff who completed a specifically designed survey, three patient focus groups, clinical interviews and visits to healthcare providers.

The Leng Review recommendations

The review makes a series of recommendations for physician associates:

  • The role of physician associate should be renamed as ‘physician assistant’, positioning the role as a supportive, complementary member of the medical team.

  • Physician assistants should have the opportunity for ongoing training and development in the context of a formal certification and credentialling programme. This should include the ability to take on added responsibilities that are commensurate with that training, including the potential to prescribe and order non-ionising radiation.

  • Physician assistants should have the opportunity to become an ‘advanced’ physician assistant, which should be one Agenda for Change band higher and developed in line with national job profiles.

  • Physician assistants should not see undifferentiated patients except within clearly defined national clinical protocols

  • Newly qualified physician assistants should gain at least two-years’ experience in secondary care prior to taking a role in primary care or a mental health trust.

  • The physician assistant role should form part of a clear team structure, led by a senior clinician, where all are aware of their roles, responsibilities and accountability. A named doctor should take overall responsibility for each physician assistant as their formal line manager (‘named supervisor’).

  • Standardised measures, including national clothing, lanyards, badges and staff information, should be employed to distinguish physician assistants from doctors.

  • A permanent faculty should be established to provide professional leadership for physician assistants, with standards for training and credentialling set by relevant medical royal colleges or the Academy of Medical Royal Colleges.

The review makes a series of recommendations for anaesthesia associates:

  • Anaesthesia associates should be renamed as ‘physician assistants in anaesthesia’ or PAA and should continue working within the boundaries set in the interim scope of practice published by the Royal College of Anaesthetists.

  • Physician assistants in anaesthesia should have the opportunity for ongoing training and development in the context of a formal certification and credentialling programme, with the ability to take on added responsibilities that are commensurate with that training, including the potential to prescribe and order non-ionising radiation.

  • Physician assistants in anaesthesia should have the opportunity to become an ‘advanced’ physician assistant in anaesthesia, which should be one Agenda for Change band higher and developed in line with national job profiles.

  • Any further expansion in the deployment of physician assistants in anaesthesia should be taken forward in conjunction with the Royal College of Anaesthetists to build safe and effective models of anaesthesia delivery that are supported by the consultant community.

  • There should be an ongoing national audit of safety outcomes in anaesthesia practice in conjunction with the Healthcare Quality Improvement Partnership to provide assurance of the safety of the physician assistants in anaesthesia role, in teams with and without physician assistants in anaesthesia.

  • A permanent faculty should be established to provide professional leadership and set postgraduate standards for physician assistants in anaesthesia, under the auspices of the Royal College of Anaesthetists.

The review makes a series of recommendations for general system-wide changes:

  • The General Medical Council requirements for regulation and reaccreditation of physician assistants and physician assistants in anaesthesia within Good Medical Practice should be presented separately to reinforce and clarify the differences in roles from those of doctors.

  • Doctors should receive training in line management and leadership and should be allocated additional time to ensure that they can fulfil their supervisory roles, and to ensure effective running of the health service.

  • DHSC should establish a time limited working group to set out multidisciplinary models of working in different settings. The group should include input from a small group of experienced leaders covering medicine, other relevant healthcare professionals, management, and human resources.

  • Safety systems should routinely collect information on staff group to facilitate monitoring and interrogation at a national level, against agreed patient safety standards, to determine any system-level issues in multi-disciplinary team working.
