What the latest figure measures

Northern Ireland’s Department of Health says the Paediatric Anaesthetic Preassessment Clinic at the Ulster Hospital can now replace 73 per cent of theatre slots affected by a late cancellation. The department announced the figure on 13 August 2026 after Health Minister Mike Nesbitt visited the service. It describes the clinic as the first nurse led service of its kind in Northern Ireland. The practical result is that a child who is ready for surgery may be offered a slot that would otherwise be unused when another child cannot proceed. The figure concerns the clinic’s ability to recover scheduled capacity after a late cancellation. It does not mean that 73 per cent of all planned operations are rearranged, or that the overall cancellation rate has fallen by that amount.1, 2

The current release follows an earlier account from the South Eastern Health and Social Care Trust, which said the pilot began in January 2025. In September that year, the Trust reported a 77 per cent reduction in late surgery cancellations. That is a different measure from the latest 73 per cent replacement rate. A reduction figure compares the number or rate of cancellations with an earlier position. A replacement figure describes the proportion of late cancellations whose vacated slots can be offered to somebody else. Both can indicate useful improvement, but they answer different questions. Neither organisation has published the underlying counts, periods, denominator definitions or calculation method alongside the public statements, so the two percentages should not be combined or read as a trend.1, 2

This distinction matters because cancellation data can describe several stages of the same pathway. A clinical problem found early may allow an operation to be postponed before the final theatre list is fixed. A problem found 48 hours before surgery may create a late cancellation but leave enough time to contact another family. Illness discovered only when the child arrives may be much harder to recover from. A service could therefore reduce some cancellations, identify others earlier and replace a proportion of the remaining slots. Each result has value, but only if the measure is labelled consistently. The published information supports the narrower conclusion that the clinic reports both an earlier reduction and a current ability to replace most late cancellation slots.1, 2

For children and families, the service is intended to make readiness for surgery visible before the day itself. For theatre teams, its reported value lies in having enough notice and a suitable alternative patient when a planned operation cannot safely go ahead. It does not remove the clinical reasons for cancellation, and replacing a slot is not automatically possible. The department says another patient is offered the theatre time where possible. That qualification recognises that the replacement child must be clinically appropriate, prepared, available and matched to the list. The achievement is therefore better understood as a coordinated pathway rather than a promise that every gap can be filled.1, 2

How the pathway works before surgery

The clinic assesses children in advance of an operation so that potential clinical issues can be identified and managed earlier. The Trust’s original account described clinical assessment, health screening, preparation for anaesthesia and support with anxiety and informed consent. These activities sit before the final decision that a child is ready to proceed on a particular day. They give the team an opportunity to gather relevant information, clarify what families need to do and refer questions that require anaesthetic review. The public material does not publish a full assessment protocol or list of eligible procedures. It should not be taken as evidence that every child follows an identical route or that nursing staff make decisions beyond the competencies and escalation arrangements defined for the clinic.1, 2

A further check takes place 48 hours before surgery. The department says families are contacted and, if a child is unwell or cannot safely proceed, the procedure can be rescheduled. Where circumstances allow, the vacated theatre slot can then be offered to another patient. Timing is central to the process. A decision made early enough gives administrators and clinicians a realistic chance to identify a suitable replacement, confirm that the family can attend and complete any remaining preparation. The call is not simply a reminder. It is a planned point at which a change in the child’s health or treatment can be raised before the journey to hospital and before a theatre team is left waiting on the day.1, 2

The pathway also includes preparation designed for children. During the ministerial visit, the team showed resources that include a Beano comic called Dennis Has an Anaesthetic and visual guides. Such material can help a child and parent understand an unfamiliar sequence without relying only on adult clinical language. The sources do not report a formal evaluation of those resources, so it would be premature to claim that they reduce anxiety or cancellations by themselves. Their documented role is more modest and useful. They provide a shared way to explain what will happen, which can support questions and help the family identify anything they have not understood before the operation date.1, 2

Early assessment cannot eliminate the uncertainty that accompanies childhood illness. A child who is well at the clinic may develop symptoms later, and a change disclosed during the 48 hour contact may still require a clinical judgement. Rescheduling is not a failure when proceeding would be unsafe. The pathway’s purpose is to bring that information into a managed process and, when possible, protect the theatre time for another child. Families should not infer that reporting illness will cost the service an operation slot or that they should minimise symptoms. The reported replacement rate depends on prompt, accurate information and on the team having a safe response when plans need to change.1, 2

Training and consultant support set the boundaries

The Department of Health says the nursing staff completed intensive, dedicated, competency based training in paediatric preoperative assessment. It also describes the service as consultant supported. Those details are essential to understanding the model. The clinic is not presented as a transfer of anaesthetic responsibility to an undefined nursing role. It is a defined service in which trained nurses carry out specified assessment work with medical support available within the pathway. The public releases do not give the curriculum, sign off process, staffing establishment or escalation criteria. Those are important local governance details, but their absence from a news announcement does not justify guessing what an individual practitioner may decide independently.1, 2, 3

National practical guidance from the Getting It Right First Time programme treats paediatric preassessment as part of building safe elective capacity. Its guide says paediatric trained preoperative nurses are well placed to deliver the work and points to a specific training course intended to support wider adoption. It also notes that patient criteria may be influenced by the available skill mix and can develop as teams gain confidence and supporting pathways become established. That approach places competence, selection and support before expansion. It is consistent with the Ulster Hospital description, where a nursing team has undertaken dedicated training and works within a consultant supported service rather than relying on a job title alone.1, 2, 3

A workable boundary needs more than a statement that support exists. Teams need agreed criteria for which children can enter the nurse led pathway, which findings require review and who is responsible for the decision to proceed, postpone or seek further information. They also need a reliable route to advice when a new concern appears during the 48 hour contact. The Ulster Hospital sources confirm the broad structure but do not publish these operating details. Any service considering a similar model would need to define them locally and test whether consultant availability matches the volume and complexity of referrals. A nominal escalation route that cannot provide timely decisions would weaken the cancellation recovery process as well as clinical safety.1, 2, 3

The model should therefore be judged as a team pathway. Nursing assessment, anaesthetic oversight, administrative coordination and theatre planning each contribute a part that the others cannot replace. A nurse may identify a concern early, but a slot is recovered only if the clinical decision is timely, another suitable child is ready and staff can contact that family. Consultant support does not diminish the nursing contribution, while nursing leadership of the clinic does not make professional roles interchangeable. The useful question is whether the pathway gives each practitioner the training, authority, information and access to escalation needed to act safely within an agreed scope.1, 2, 3

Why readiness matters to theatre capacity

A theatre session brings together a child, family, surgeon, anaesthetic team, nursing staff, equipment, beds and recovery capacity. When one planned case falls out late, the time cannot be recovered merely by finding another name on a waiting list. The alternative child must be suitable for the procedure and the available session, have completed the necessary assessment and be able to attend at short notice. The GIRFT guide recommends planning enough time for preassessment to reduce cancellations on the day of surgery. It also supports maintaining a pool of patients who are ready and could substitute when a cancellation occurs. The Ulster Hospital replacement figure describes this principle operating through a local clinical and administrative pathway.3, 1, 4

Readiness is different from urgency or waiting time alone. A child who has waited longer may not be suitable for the exact procedure, team or equipment available in the vacated slot. Another family may be unable to reorganise transport, work and caring responsibilities at short notice. A replacement process therefore needs transparent clinical and operational criteria. The sources do not explain how children are selected when more than one could use a slot, so no conclusion can be drawn about prioritisation at Ulster Hospital. What can be said is that advance assessment creates information that is necessary for a safe offer. It narrows the gap between an empty place and a child who can actually use it.3, 1, 4

The Northern Ireland Elective Care Framework places the wider problem in a system context. The Department of Health says the framework combines targeted investment to treat more people with reform intended to address long term capacity and productivity problems. A preassessment clinic is one operational response within that agenda. It can help services use theatre time already planned, but it cannot create all of the staff, beds, operating time or community support required to clear a waiting list. Nor does a recovered slot prove that total activity has increased if another constraint later prevents the operation. Measures of theatre use need to sit beside completed procedures, patient outcomes and the reasons that planned care did not take place.3, 1, 4

The benefit to a family is not confined to theatre utilisation. Learning before travel that an operation should be postponed may avoid an unnecessary journey, fasting and a day of disrupted arrangements. Receiving clear preparation can also make the practical demands of attendance easier to anticipate. Those are plausible consequences of the described pathway, but the public reports do not provide patient experience data, travel savings or measures of anxiety. Future evaluation should ask families directly and report who responded. Efficiency claims are strongest when they are accompanied by evidence that the service remains acceptable, accessible and safe for the children whose plans change as well as those offered a replacement slot.3, 1, 4

What the published percentages cannot show

The 73 per cent replacement rate is the clearest current result, but the public release does not state how many late cancellations occurred, how replacement was defined or over what period the proportion was calculated. A rate based on 73 of 100 cancellations would provide a different level of certainty from eight of 11, even though the rounded percentage would be similar. It is also unclear whether an offered slot counts as replaced or whether the alternative operation had to be completed. These gaps do not invalidate the reported achievement. They limit what readers can infer and what another service can use as a benchmark.1, 2

The same caution applies to the Trust’s earlier 77 per cent reduction claim. Its September 2025 article says the pilot launched in January 2025, but it does not publish the baseline period, the number of cancellations before and after the change or adjustments for the mix and volume of surgery. Seasonal childhood illness, changes in theatre schedules and other service improvements could affect a comparison. The source attributes the reduction to the clinic, yet the published data are not detailed enough for an independent causal analysis. Reporting the claim accurately means retaining both its stated result and its evidential limit.1, 2

The two figures may coexist without contradiction. The clinic could have reduced late cancellations compared with an earlier baseline and then replaced 73 per cent of those that still occurred. It is also possible that the organisations used different periods or definitions. Without the calculation notes, choosing between those explanations would be speculation. The responsible presentation is to keep the measures separate. The 77 per cent figure is an older Trust claim about reduction. The 73 per cent figure is the current departmental claim about replacement. Neither should be subtracted from the other or treated as evidence that performance has risen or fallen since 2025.1, 2

A fuller public dataset could show monthly planned cases, cancellations by timing and reason, the number of vacated slots offered to another family, the number accepted and the number of replacement operations completed. It could also include cancellations caused by the replacement child becoming unwell, list overruns and bed or staffing constraints. Balancing information should cover safety incidents, unplanned admissions, postponement after arrival and family experience. These measures would help distinguish earlier identification from genuine additional activity. They would also show whether the approach works consistently rather than only during periods when a sufficiently large pool of ready patients is available.1, 2

What wider adoption would require

The Ulster Hospital service offers a practical example for other paediatric surgical pathways, but its components should travel together. Dedicated competency based training, consultant support, agreed patient criteria, advance assessment, a 48 hour contact and administrative capacity to reschedule or make another offer all appear in the source record or national guidance. Copying only the nurse led label would miss the mechanism. A hospital also needs enough suitable children prepared in advance and a way to match them to the available list. The GIRFT guide makes clear that criteria depend partly on local skill mix and support, which means adoption should be designed around the receiving service rather than imposed as a uniform task list.3, 1, 2, 4

Implementation would need protected training and supervision time as well as a plan for maintaining competence. New staff require a route into the service, while experienced staff need access to review when clinical criteria or surgical activity change. Consultant support must be defined in rotas and response arrangements. Administrative colleagues need authority and current contact information to act quickly when a slot becomes available. Digital records should make the assessment and decision visible to the teams preparing the list without creating duplicate documentation. These are resource requirements, even if better use of theatre time later produces savings or additional activity.3, 1, 2, 4

Services should also examine access. A 48 hour contact assumes that the family can be reached and can communicate any change clearly. Interpreting support, accessible formats and more than one contact route may be needed. Short notice replacement offers can advantage families with flexible work, transport and caring arrangements unless the process is monitored. That does not make the offers inappropriate, but it creates a reason to record who can accept them and why others cannot. A service intended to improve capacity should not leave children with greater practical barriers repeatedly passed over because their families need more notice.3, 1, 2, 4

The next useful step is transparent evaluation rather than a broader claim about replacing one profession with another. The reported service has a defined paediatric purpose, a trained nursing team and consultant backing. Its current result is specific and promising. It says that 73 per cent of late cancellation slots can be replaced, not that 73 per cent of cancellations have disappeared. Publishing the counts, definitions, safety measures and family experience would allow other services to judge the scale of the benefit and the resources behind it. That would preserve the feature that makes the model credible in the first place, which is a supported pathway built around preparation and timely clinical information.3, 1, 2, 4
