NHS uses nurses as doctor substitutes amid UK safety fears

Across the United Kingdom, growing concern is emerging over patient safety as hospitals increasingly rely on senior nurses to fill gaps left by a shortage of doctors. New figures obtained through freedom of information requests suggest that nearly half of NHS organisations are now deploying advanced practitioners—mainly highly trained nurses—to perform duties traditionally carried out by doctors, including in emergency departments, critical care units and neonatal services.

The development has triggered a sharp debate within the medical community, with warnings that so-called “doctor substitution” may risk lowering the standard of care, while nursing representatives insist that advanced practitioners are highly qualified professionals working within appropriate clinical boundaries.

The data, compiled by the British Medical Association, indicates that hospitals across England, Scotland, Wales and Northern Ireland are increasingly using advanced practitioners (APs) to cover rota shortages. These staff members are often deployed in senior clinical roles, sometimes stepping into positions equivalent to junior or middle-grade doctors.

Advanced practitioners are typically experienced nurses who have undertaken additional postgraduate training, often at master’s level. They are intended to support multidisciplinary healthcare teams, but the findings suggest their role is expanding in ways that some doctors argue goes beyond safe practice.

According to NHS guidance issued in England, advanced practitioners should not replace doctors, even though they may work closely alongside them. The guidance emphasises that while APs have valuable and advanced clinical skills, they are not trained to the same breadth or depth as medical doctors and therefore should not routinely be used as substitutes.

Despite this, several NHS trusts have confirmed that APs are being used directly on medical rotas. In some cases, they are covering shifts that would normally be filled by senior house officers or registrars, particularly in overstretched departments where recruitment gaps remain unresolved.

One NHS trust, Birmingham Women’s and Children’s NHS Foundation Trust, stated that advanced practitioners are “trained and employed to work in the same role as their medical colleagues,” adding that they regularly participate in doctor rotas depending on their level of training. Similarly, Barking, Havering and Redbridge University Hospitals NHS Trust reported that AP coverage often aligns with junior or middle-grade doctor responsibilities.

In Scotland, health boards including Dumfries and Galloway and Forth Valley have also confirmed that advanced practitioners are included in medical rotas, particularly in critical care and out-of-hours services. In some cases, they are also part of paediatric and neonatal teams.

One of the most concerning findings from the BMA survey is that more than half of responding NHS organisations allow advanced practitioners to hold crash bleeps—emergency devices traditionally reserved for doctors. These bleeps allow immediate response to life-threatening situations and are typically carried only by medically qualified staff with extensive training in acute care.

For critics, this marks a significant shift in clinical responsibility. Dr Mel Ryan, a paediatric registrar and spokesperson for the BMA on workforce issues, warned that the situation reflects a systemic problem in staffing policy rather than a safe evolution of roles.

“There is a vast difference in the level of education and training between doctors and advanced practitioners,” she said. “APs cannot substitute for doctors, yet alarmingly many employers are doing just that. This is simply not safe.”

She further argued that some NHS employers may be motivated by cost pressures, as advanced practitioners are generally less expensive to employ than doctors. According to her, the solution should be focused on increasing the number of doctors in training and recruitment rather than expanding substitution roles.

However, the nursing profession strongly rejects the suggestion that patient care is being compromised. The Royal College of Nursing responded forcefully, stating that advanced nursing practice is a highly skilled and autonomous field supported by postgraduate education and extensive clinical training.

A spokesperson said these nurses are “central to the delivery of safe and effective care across many services” and stressed that they are not intended to replace doctors but to contribute as part of multidisciplinary teams. The organisation also warned against what it described as attempts to undermine nursing roles in the wider workforce debate.

Despite the disagreement, the issue has been intensified by real-world cases where advanced practitioners were involved in serious clinical incidents. In Manchester, an inquest concluded that a patient died after an advanced nurse practitioner failed to identify a risk of blood clots during a routine consultation. The patient was later diagnosed too late to prevent a fatal pulmonary embolism.

In another case at Rotherham General Hospital, a consultant nurse carrying out complex endoscopic procedures was found to have delivered substandard care between 2016 and 2021. An official inquiry reported that at least 68 patients experienced serious harm or death during that period, highlighting the risks associated with substituting highly specialised medical procedures when consultant doctors were unavailable.

These cases have been cited by critics as evidence that role substitution can lead to dangerous gaps in clinical judgement, particularly in complex or high-risk medical situations.

The debate has now placed NHS workforce planning under renewed scrutiny. Hospitals across the UK continue to struggle with long-term shortages of doctors, especially in emergency medicine, paediatrics and general practice. At the same time, patient demand has risen steadily, increasing pressure on already stretched services.

Supporters of expanded advanced practitioner roles argue that they are essential to keeping services running safely during staffing crises. They point out that APs often bring years of clinical experience and can manage a wide range of patient care tasks, freeing doctors to focus on the most complex cases.

But opponents argue that the line between support and substitution is becoming blurred. They warn that without clear safeguards, patients may not always be aware whether they are being treated by a doctor or another clinician operating in a similar role.

NHS England has responded by reaffirming its position that advanced practitioners are valuable members of clinical teams but should not replace doctors. A spokesperson said their use must always align with training, competence and patient safety requirements, and that staff are encouraged to raise concerns if they believe care is being compromised.

As the debate continues, policymakers face increasing pressure to address the root causes of the doctor shortage, including training capacity, retention issues and working conditions within the NHS. For now, however, many hospitals remain reliant on advanced practitioners to fill critical gaps in care delivery.

The controversy highlights a broader challenge facing modern healthcare systems: balancing workforce shortages with patient safety, while defining the evolving roles of medical and nursing professionals in an increasingly strained system.

For patients and clinicians alike, the central question remains whether the current approach represents a necessary adaptation—or a growing risk that could reshape standards of care within the NHS.
