Never Events are serious, largely preventable patient safety incidents that should not occur when nationally recognised safeguards, guidance and systems are in place. For NHS, independent and other care providers, they are not simply isolated errors. They are signals that systems, processes, environments, governance and human factors need to be understood and improved.
Promethean HD provides specialist human factors consultancy, patient safety training, PSIRF education, governance support, investigation insight and bespoke organisational development for healthcare providers across the United Kingdom. We help teams move beyond blame, understand why things happen, and design safer, more resilient systems of care.
What are Never Events in the NHS?
A Never Event is a serious patient safety incident that is considered preventable because national guidance or safety recommendations should already have been implemented. NHS England describes Never Events as patient safety incidents that are wholly preventable because guidance or safety recommendations that provide strong systemic protective barriers are available at a national level and should have been implemented by all healthcare providers.
The term can be misleading if it causes organisations to look only for individual error. In practice, a Never Event should trigger a human factors-informed learning response that examines how people, systems, tools, workflows, environments, organisational pressures and governance arrangements interacted.
Promethean HD supports healthcare teams to apply this kind of systems thinking through human factors training, PSIRF education, governance advice, investigation support and expert consultancy.
Why Never Events are a human factors issue
Never Events are often described as preventable, but that does not mean they are simple. They occur in complex, pressured clinical environments where communication, workload, interruptions, equipment design, supervision, handovers, local procedures, leadership and organisational culture can all influence how care is delivered.
Human factors helps healthcare providers understand the fit between people, equipment, environments, tasks, teams, processes and organisational conditions. This is essential because safe care cannot depend on people being perfect. Safer systems are designed to make the right action easier, the wrong action harder, and recovery from error more likely.
Promethean HD helps NHS, independent and other care providers move from asking, “Who made the mistake?” to asking, “How did the system make this outcome possible, and how can we design it to be safer?”
Examples of NHS Never Events
Examples of Never Events listed in NHS England guidance include:
-
Wrong-site surgery, including surgery on the wrong patient or wrong body part.
-
Wrong implant or prosthesis, such as an incorrect lens, joint component or device.
-
Retained foreign object after a procedure, such as a swab, instrument, needle or guidewire.
-
Medication administered by the wrong route.
-
Overdose of insulin due to abbreviations or use of the wrong device.
-
Overdose of methotrexate for non-cancer treatment.
-
Mis-selection of high-strength midazolam during conscious sedation.
-
ABO-incompatible blood component transfusion or organ transplantation.
-
Misplaced nasogastric or orogastric tubes.
-
Falls from poorly restricted windows, scalding of patients, or oxygen patients being connected to an air flowmeter instead of oxygen.
These events are often associated with weaknesses in checking systems, communication, task design, local safety standards, equipment use, documentation, handover, environmental design and situational awareness. Promethean HD’s human factors training and consultancy can help providers review these risks before harm occurs, strengthen local safety processes and embed practical learning into everyday work.
Never Events in NHS England, NHS Wales and NHS Scotland
NHS England
In NHS England, Never Events are managed through the NHS England Never Events policy and framework. The framework explains how NHS-funded services should identify, investigate and respond to Never Events, and the list has evolved over time as clinical and safety understanding has developed.
NHS England has consulted on the future of the Never Events framework and has recognised that the framework needs to change. While a new approach is developed, the existing framework remains active and providers are expected to continue recording incidents that meet the Never Event criteria through national reporting processes.
NHS Wales
In NHS Wales, the Welsh Government’s Never Events policy and incident list defines Never Events as serious incidents that are wholly preventable because national guidance or safety recommendations are available and should have been implemented by all healthcare providers.
The Welsh policy requires Never Events to be investigated fully but proportionately, regardless of outcome, in line with patient safety incident reporting requirements. It emphasises understanding where safety measures failed, learning lessons and taking targeted action to prevent recurrence.
NHS Wales also emphasises meaningful engagement with patients, families and carers from the beginning and throughout the investigation, together with openness and transparency. The Welsh policy has been updated to reflect changes to the incident list, including the removal of wrong tooth extraction from the Never Events list and the suspension of undetected oesophageal intubation while further work is undertaken.
NHS Scotland
In NHS Scotland, serious preventable harm is generally managed through the national adverse-events framework rather than a directly equivalent public-facing Never Events list. Healthcare Improvement Scotland’s national framework focuses on reviewing and learning from adverse events, including Significant Adverse Event Reviews, patient and family involvement, staff support, identifying learning and sharing improvement.
For organisations working across the United Kingdom, this means the language and reporting route may differ between England, Wales and Scotland, but the underlying safety challenge is similar: understanding how systems, people, tasks, environments and governance arrangements interact, and then designing more reliable care.
Promethean HD works with healthcare providers across the United Kingdom to support human factors education, patient safety improvement, governance, investigations and system learning in ways that are adapted to the relevant national policy context.
What happens after a Never Event?
After a Never Event, providers should report the incident, inform and involve the patient and/or family, investigate what happened, understand contributory factors, identify learning and take action to reduce the risk of recurrence.
A strong response should avoid superficial conclusions and generic action plans. It should explore how work was actually done, what pressures were present, what made sense to staff at the time, what barriers existed, what barriers failed, and what practical changes would make safer care more reliable.
Promethean HD can support organisations with human factors-informed investigation, PSIRF-aligned learning responses, governance reviews, team education and practical improvement planning. This helps providers move beyond simple retraining or reminders and address the deeper system conditions that contribute to avoidable harm.
Are Never Events increasing or decreasing?
The picture is mixed. Analysis of NHS England Never Events from 2018 to 2024 identified 2,485 Never Events, including 1,091 wrong surgeries, 561 retained objects, 266 wrong implants and 198 medication-related Never Events. The study found an overall downward trend, but also showed that some categories fluctuated, levelled out or remained stubbornly persistent.
Wrong implants showed a declining pattern, but retained objects and wrong surgery fluctuated. Medication-related Never Events levelled out, wrong-lens incidents remained stable, and misplaced nasogastric tubes, falls and mismatched blood transfusions were described as stationary without a clear pattern.
This means healthcare providers should be cautious about assuming that Never Events are steadily disappearing. Definitions, reporting arrangements and the Never Events list have changed over time, which makes direct year-on-year comparison difficult. Recent national data also shows that Never Events continue to occur in the hundreds each year in England, demonstrating that they remain a live patient safety and governance challenge.
For Promethean HD, this is where human factors work is especially important. Persistent or fluctuating Never Event categories often indicate that the system is still relying too heavily on people remembering, checking, noticing and speaking up in pressurised conditions, rather than on stronger, more reliable system design.
Why do Never Events still happen?
Never Events continue to occur because healthcare is complex and safety barriers are not always strong enough, consistent enough or embedded deeply enough into daily work. Some incidents classed as Never Events rely heavily on administrative and behavioural controls, such as checklists, policies, training and vigilance. These controls are important, but they are vulnerable to workload, interruption, fatigue, ambiguity, variation and competing priorities.
Common contributory factors include communication breakdowns, reduced situational awareness, fatigue, inadequate staffing, inconsistent team composition, increasing caseloads, limitations in equipment or workspace design, inconsistent local standards and production pressures that compete with safety processes.
Promethean HD helps providers address these risks through human factors training, just culture development, PSIRF education, governance support, investigation insight and bespoke team or organisational coaching. Our approach helps organisations identify risk earlier, strengthen system design and create learning cultures that support safer care.
High-profile incidents and what they teach us
High-profile incidents involving wrong-patient procedures, wrong-site surgery, retained surgical items and wider patient safety scandals show why Never Events should be treated as system learning opportunities rather than isolated failures.
HSSIB has investigated wrong-patient and wrong-procedure incidents, including an outpatient setting where a patient was mistaken for another patient and received a procedure intended for someone else. Such incidents show how patient identification, waiting-room processes, consent checks, communication and environmental design can combine to create risk.
HSSIB has also investigated retained surgical swabs following invasive procedures. Retained foreign objects can lead to distress, further surgery, prolonged hospital stay, infection risk, time away from normal life and, in severe cases, death. These events highlight the importance of reliable reconciliation processes, equipment design, team communication and escalation when counts or imaging results are unclear.
Wider patient safety scandals, such as the Ian Paterson case, should not automatically be described as Never Events unless a specific incident meets the formal definition. However, they are relevant because they demonstrate the importance of governance, oversight, patient voice, speaking up, professional accountability and organisational culture in preventing avoidable harm.
Promethean HD helps organisations learn from both formal Never Events and wider serious patient safety concerns by applying human factors, systems thinking and governance expertise to real-world healthcare complexity.
