Expanding Non-Doctor Healthcare Roles: Are We Rushing Ahead Without Safety Checks?

The NHS faces an increasingly difficult balancing act. With persistent doctor shortages and growing patient demand—driven particularly by an ageing population—the health service has increasingly turned to expanding the roles of non-medical professionals including physician associates, advanced nurse practitioners, and specialist pharmacists. However, a prominent healthcare leader is now warning that this expansion may be happening too fast and without sufficient safety safeguards in place.

Dr Partha Kar, a consultant in diabetes and endocrinology at Portsmouth Hospitals NHS Trust, has raised significant concerns about the expansion of non-doctor healthcare roles in pursuit of faster patient access. Writing in the British Medical Journal in early March, he argues that whilst the intentions behind expanding professional scope are sound—improving public access and creating more avenues for care—the implementation risks sacrificing safety, quality, and efficiency.

The expansion of non-medical roles across the NHS is not new, but it has accelerated over the past decade. With England experiencing persistent shortages of doctors, and with workforce planning suggesting these pressures will intensify, NHS leaders and government officials have increasingly looked to other healthcare professionals to fill gaps. According to NHS workforce data, vacancy rates in adult social care and broader healthcare settings stand at approximately 8–10% nationally, creating genuine staffing pressures that clinical leaders must address.

This approach is not inherently problematic. The NHS has successfully integrated multidisciplinary teams for decades, with specialist nurses, physiotherapists, and other professionals delivering excellent care within clearly defined scopes of practice. However, Dr Kar and other experts argue that recent expansion plans have not been accompanied by robust safety frameworks.

The key concern centres on three critical areas: training standards, supervision capacity, and regulatory oversight. Dr Kar highlights that whilst physician associate roles have expanded significantly—including through planned further expansion—little progress has been made on setting adequate training standards for these professionals. Unlike doctors, who undergo years of structured medical training and formal assessment, training pathways for physician associates vary considerably across the UK.

Supervision presents another major challenge. Senior doctors across the NHS already struggle to fit adequate supervision of junior doctors and other healthcare professionals into their workload—a well-acknowledged but often unspoken problem within the health service. Yet workforce planning appears to assume that robust supervision will continue to be provided, even as doctors have less time available and non-medical clinicians take on increasingly complex tasks.

The British Medical Association has raised similar concerns, noting that patient safety risks can emerge when non-medical clinicians are supported by their employers to work outside their competency, or without sufficient supervision from a doctor where necessary. Such situations can lead to delayed diagnosis, incorrect treatment, inability to manage complications, and inefficient fragmented care.

Compounding these concerns is the state of healthcare regulation itself. The Care Quality Commission, responsible for monitoring patient safety, was recently found by the Darzi review to be “unfit for purpose”. Healthwatch, which advocates for patients, is being closed. Meanwhile, the General Medical Council, which regulates doctors, has been diluting its regulatory functions. This creates what Dr Kar describes as “unclear lines of responsibility”—potentially a dangerous situation when patient safety oversight is needed most.

Dr Kar does not argue against role expansion per se. Instead, he emphasises that any discussion of expanding professional scope must be built on three core principles: appropriate training, adequate supervision, and strong regulation. When these principles are upheld, expanding roles can be genuinely beneficial. However, previous attempts at professional scope expansion have failed precisely because they compromised these principles.

The role of royal colleges is crucial here, he argues. These professional bodies should be leading on training standards and competency frameworks, though some appear more focused on financial sustainability and international expansion than on setting robust domestic standards.

Whilst the full consequences of rapid role expansion may not be apparent for years, Dr Kar suggests that concerning signs are already emerging. Risks include overreliance on diagnostic tests and consultations—as non-medical professionals may compensate for less extensive training by ordering more investigations—alongside the potential for missed diagnoses and treatment errors.

For patients across Kent and Medway, these developments carry direct implications. The Kent and Medway NHS Trust, like all NHS organisations, faces significant staffing pressures and has expanded non-medical professional roles to maintain service provision. Whilst many physician associates and advanced nurse practitioners deliver excellent care, Dr Kar’s concerns suggest patients should be aware of who is providing their healthcare and what their professional background is.

If you have concerns about the scope of care provided by non-medical professionals during NHS appointments, you have the right to ask about their qualifications and training, and to request review by a doctor where appropriate. For complex health matters, it remains important to access consultant-led care. NHS England encourages patients with concerns about the quality or safety of their care to contact their local Healthwatch or GP practice.

Key Takeaways

• The expansion of non-doctor healthcare roles has accelerated due to persistent NHS staffing shortages, but leading clinicians now warn this may be outpacing essential safety frameworks.
• Three critical safeguards—appropriate training standards, adequate supervision, and strong regulation—are not yet firmly established for roles like physician associates.
• Regulatory bodies responsible for patient safety oversight appear to be weakening, creating gaps in accountability.
• Whilst multidisciplinary working remains valuable, experts stress that role expansion must be built on evidence of safety and quality, not workforce pressure alone.
