In autumn 2024, Health Secretary Wes Streeting commissioned Gillian Leng, President of the Royal Society of Physicians, to conduct an independent review of the safety and scope of roles of Physician Assistants (PAs) and Anesthesia Assistants (AAs) in the NHS[1][7]. Leng's report published on 16 July 2025 contains 18 recommendations which the government has fully accepted and will start implementing immediately[1][2][5]. He recommends renaming PAs to "physician assistants" and AAs to "physician assistants in anesthesia" to emphasize their supportive role to physicians[1][2][3]. New PAs must obtain at least 2 years of experience in secondary care before working in primary care or psychiatry[1][2]. Each PA must have a designated physician as a formal supervisor and may not independently triage or treat indeterminate patients[1][2][3]. Standardized markings such as clothing, tags, and badges are introduced to distinguish PAs from physicians[1][2][5]. The report draws on input from academics, clinicians, NHS employers, patients and international experts[1][6].
