Becoming the bridge: Supporting student learning in a tertiary paediatric centre

Rhianna Madden-Hansle — 2026-06-09

This reflective piece explores my transition as a paediatric trainee in the second year of paediatric training from learner to educator within a tertiary paediatric centre. It highlights the role trainees play in supporting student learning in complex clinical environments, and the shift from viewing teaching as a separate activity to recognising it within everyday practice. Drawing on experience from my hospital’s teaching programme, it reflects on how teaching shapes professional identity and contributes to more accessible and inclusive learning for students.

Communication-Focused Simulation to Enhance Paediatric Trainee Confidence in Difficult Conversations

Ilana Gluck — 2026-06-09

Objective: To design, deliver and evaluate the impact of a trainee-led simulation programme focused on paediatric communication skills, addressing an identified gap in experiential training for difficult conversations.

Background: Simulation training is a core component of paediatric education, commonly used to rehearse emergency and technical scenarios. In contrast, communication skills are often learned opportunistically despite being fundamental to safe and compassionate paediatric practice. Trainees frequently report limited confidence in

these situations. We developed a series of communication-focused simulation sessions, to provide a safe environment in which trainees could practise, observe and reflect on challenging interactions.

Methods: We delivered a series of trainee-led simulation sessions for mixed-grade learners. Each session involved 10–20 participants and lasted one hour in protected teaching time. Sessions involved pre-planned scenarios with detailed patient backgrounds and discussion points. Example scenarios included breaking bad news in the context of a new brain cancer diagnosis, explaining the importance of antibiotics to a mother who was not consenting to treatment for her septic baby and managing a disclosure of sexual abuse for a teenager presenting with non-specific symptoms.

An SHO initiated with registrar support introduced part-way through. Sessions were facilitated by senior trainees and incorporated individual reflection, feedback from the actor, peer feedback and facilitated group discussion. Participants were invited to actively take part or observe. Written feedback was collected anonymously following sessions via online forms.

Results: 80% of respondents reported increased confidence in managing challenging communication scenarios after attending the simulation, highlighting facilitation quality, safety and the value of structured debriefing. One participant reported feeling “grateful my first experience of this was a simulation rather than real life,” while others described the sessions as providing “practical and detailed advice” for breaking bad news.

Observers also reported significant learning, noting improved understanding of how to approach difficult conversations. Facilitation style and psychological safety were repeatedly cited as strengths, with structured feedback and debriefing described as the most valuable component, with one participant commenting that the feedback was “the best part of the sim.”

Conclusion: Communication-focused simulation is a valuable and underutilised educational tool in paediatric training. Our trainee-led programme is low cost, reproducible, and demonstrates that well structured scenarios with skilled facilitation and reflective debriefing, can improve confidence and preparedness for challenging clinical conversations. Incorporating communication focused simulation, alongside traditional emergency training, equips paediatric trainees for the realities of clinical practice and ultimately enhances patient and family care.

From Senior Trainee to Consultant: Addressing an Educational Gap in Paediatric Training

Leeha Singh — 2026-06-09

Background: The transition from senior trainee to consultant represents a critical stage in paediatric training. Despite achieving clinical competence, trainees report limited structured support for consultant-specific responsibilities, such as applications, governance, and leadership. This gap contributes to transition anxiety, reduced confidence, and variable preparedness at the point of appointment.

Aim: To design, implement, and evaluate a sustainable, trainee-led programme supporting the transition from senior Paediatric trainee to consultant.

Methods: The Transition to Consultant (T2C) programme (2024–2026) organised by London school of Paediatrics trainee committee (Education subgroup), utilized a longitudinal design over two academic years. It employed interactive lectures, case-based discussions, and experiential mock interviews led by senior trainees and supported by recently appointed consultants.

Results: Over 130 ST5+ Paediatric trainees attended between 2024 and 2026. Feedback demonstrated high levels of satisfaction, with trainees reporting improved clarity regarding recruitment and increased confidence in interview preparation. Demand significantly exceeded capacity, with 95 applicants for 50 places in the most recent cycle.

Conclusion: A trainee-led consultant transition programme is feasible, sustainable, and highly valued. This model transforms uncertainty into preparedness and is transferable across specialties.

Improving Paediatric A&E Environments for Neurodiverse Children and Young People

Varnika Horsley — 2026-06-09

Background

Paediatric emergency departments (PEDs) can present significant sensory overload to neurodiverse children, often resulting in challenges with accessing healthcare. The RCPCH Facing the Future Standards for Paediatric Care advises that PEDs adapt to suit the needs of children with complex needs, and the design and planning of departments should involve feedback from patents and families.1 Ideally, many departments would assign neurodivergent patents to a cubicle upon arrival to mitigate sensory overload, but such spaces are frequently at capacity due to high clinical acuity. This necessitates alternative adjustments to facilitate equitable care for these patients.

Objectives

The primary objective was to run a cross-site patient feedback survey at two PEDs at two linked hospitals to understand theexperience of neurodiverse patients in the emergency department waiting room. The secondary aim is to identify possible areas for improvement.

Design & Intervention
A 15-question survey was created using a mixture of Likert scale, binary and short answer open questions. The survey was advertised in the waiting room at the two hospitals on a poster with a QR code and hard copies were also distributed to families with neurodiverse children aged 0-15 years. Responses were collected from November 2024 to February 2026.

Results
79 responses were obtained. None of the patients had a hospital passport or emergency care plan communicatng their needs.72% (57/79) said the waiting room is overwhelming for their child. After triage, 50.6% (40/79) would prefer a quiet room to wait for assessment and 23% (18/79) would also like to provide their phone number and wait elsewhere until called. Items that wouldhelp children to remain calm in the waiting room: stress balls (60.8%, 48/79), headphones (48.1%, 38/79), story books (40.5%,32/79) and barrier screens (26.6%, 21/79). 62% (49/79) believed it would be beneficial for their child to interact with a playtherapist in PED.

Implications & Wider Relevance
Our trust aims to provide a sustainable approach to the emergency care of neurodiverse children. We suggest adjustments such as updating the trust website for better preparation on attending PED, use of hospital passports, distraction tools and creative technology-based solutions for managing the waiting area.

Review on the use and applications of Near-Infrared Spectroscopy (NIRS) in critical care patients in Neonatal Intensive Care Unit (NICU)

Shailpriya Nand — 2026-06-09

Background

Near-Infrared Spectroscopy (NIRS) is a non-invasive optical technology that continuously measures oxygen-dependent changes in haemoglobin absorption, providing insights into regional cerebral oxygenation (rSO2). By quantifying oxyhaemoglobin (cO2Hb) and deoxyhaemoglobin (cHHb) levels, NIRS offers valuable real-time data on cerebral perfusion and tissue oxygenation.

Clinical Applications of NIRS

NIRS is widely used in critical care settings, particularly during cardiac surgeries, extracorporeal membrane oxygenation (ECMO), where it detects cerebral desaturation suggesting better neurological outcomes. Unlike pulse oximetry, NIRS is effective in non-pulsatile scenarios and offers continuous, hands-free monitoring during surgeries without recalibration.

NIRS in Neonates

In neonates, NIRS is instrumental in detecting conditions such as neonatal asphyxia and monitoring cerebral oxygenation during cardiac catheterisation and surgery. Its accuracy is enhanced by minimal interference from extra-cranial tissue layers, allowing early detection of brain injuries and adverse neurological outcomes. Studies demonstrate its utility in assessing cerebral perfusion during ECMO, including the effects of carotid and jugular vein ligation.

NIRS in Neonatal ECMO

NIRS is especially valuable in neonates on ECMO, offering continuous, non-invasive bedside monitoring. It detects cerebral desaturation, correlates rSO2 changes with impaired cerebral autoregulation, enabling early intervention for complications such as ischaemic stroke, intracranial haemorrhage, and seizures. Studies demonstrate its utility in assessing cerebral perfusion during ECMO, including the effects of carotid and jugular vein ligation.5 Furthermore, international guidelines (ELSO) recognise NIRS as a standard monitoring tool which, in combination with continuous EEG, and cranial ultrasound plays an essential role in the early detection of acute neurological events.

Limitations of using NIRS

Despite its potential, NIRS faces challenges such as limited tissue penetration, dependence on systemic factors (e.g., low cardiac output, hypoxia, and anaemia), and algorithmic constraints. It provides relative rather than absolute values, lacks quantitative precision, and may fail to immediately reflect clinical events, raising questions about its impact on long-term outcomes.

A lack of standardised rSO2 thresholds remains a key challenge. Studies in adults have proposed thresholds (rSO2 <50%: point to intervene, rSO2<40% or a 20% from baseline: critical.7,8 Yet, these are potentially unsuitable for neonates due to their distinct cerebral physiology. Additionally, variability in venous-to-arterial blood ratios and immature cerebral circulation complicates the interpretation of NIRS data in the neonatal population.

Conclusion

NIRS is a pivotal tool in neonatal and critical care, particularly for ECMO patients, offering real-time insights into cerebral oxygenation. However, standardised protocols and integration with complementary modalities are essential to fully realise its potential in improving long-term neuro-developmental outcomes.

Parental insight into the management of crying infants

Aamena Nasir — 2026-06-09

Objectives

Shaken Baby Syndrome (SBS) is a preventable yet devastating cause of infant injury, frequently triggered by caregiver stress in response to persistent crying. The ICON campaign (“Infants Cry, You Can Cope”) seeks to normalise infant crying, equip parents with coping strategies, and reduce the risk of SBS. Despite its national reach, awareness among fathers remains comparatively limited. This project focused on raising awareness of the ICON campaign specifically among fathers, aiming to encourage positive coping behaviours and reduce the risk of shaken baby incidents.

Methods

This qualitative study included two audit cycles. Parents, of a child less than 1-year-old, were selected on an ad hoc basis in the paediatric assessment unit. Engagement activities included questionnaires, discussions, distribution of campaign materials, and one informal feedback session. Using informal discussions and accessible ICON materials allowed for a more conversational and less clinical environment, which helped participants feel comfortable sharing their experiences. This was important given the sensitive nature of topics such as stress, coping, and infant crying. To enhance participation, principles of appreciative inquiry were used, highlighting parents’ existing strengths in caregiving and creating a constructive space for sharing experiences. Positive feedback was deliberately emphasised to reinforce helpful behaviours, such as recognising when to pause, safely hand over the baby, or seek support.

Results

62 parents were a part of the study. Written feedback recorded in the questionnaires showed participants described the ICON messaging as ‘simple’, ‘memorable’, and ‘reassuring’. Feedback showed that ICON messages provided reassurance that persistent crying is a normal developmental phase rather than a sign of poor parentng. These findings imply tailoring public health campaigns to fathers and integrating positive feedback mechanisms that strengthen engagement and behaviour change. Discussions with parents revealed general stress as a contributing factor to response to their crying infant. Utilising ICON messaging within this broader context, allowed parents to realise that overcoming stress can help them be better equipped when dealing with their crying infant.

Conclusion

This project demonstrates that strengths-based approaches can extend the reach and awareness of the ICON campaign. Outcomes from the project demonstrated that father-focused engagement is both feasible and impactful. Overall, parents valued the ICON messaging and described confidence in their ability to soothe and manage their infant during episodes of crying.

Experiences and barriers to implementing the Low-Risk Febrile Neutropenia Pathway in a busy District General Hospital

Georgina Miles — 2026-06-09

Objectives

1. To assess awareness of the local Low-Risk Febrile Neutropenia pathway.
2. To understand how staff can be supported to feel safer and more comfortable using homecare protocols.
3. To assess parental perception of the pathway according to staff members.

Background

While Febrile Neutropenia (FN) remains a medical emergency requiring rapid hospital assessment, advancements in supportive care mean that clinically significant infections are now rare. Accurately identifying low-risk FN patients can safely reduce duration of hospital stays and exposure to IV antibiotics and nosocomial infections, benefiting pareents, families, and
hospital capacity.

The Children’s Cancer and Leukaemia Group recommends an Australian-UK-Swiss (AUS) based homecare protocol, which has been demonstrated to safely identify children with low-risk FN
and forms the basis of trust’s policy.^1,2 This service evaluation aimed to highlight barriers to implementing this protocol.

Methods

A 21-set questionnaire (divided into two surveys) was sent to all resident doctors, consultants, and nurses in paediatrics.

Survey questions assessed job role; experience in paediatric oncology; awareness of FN risk stratification; and criteria for homecare and follow-up. Likert scales and free-text were used to assess staff confidence and experience, feedback on parental views of the pathway and recommendations for improvement.

Results

43 responses were received (5% consultants, 86% resident doctors and 9% nurses).

Awareness:
81% of respondents were aware of the low-risk FN pathway and most (63%) knew the definition of febrile neutropenia. The majority (86.6%) could not recall the components of the AUS score but most (62%) knew where to find the information.

Confidence:
Despite knowledge of the protocol, few respondents (35%) reported feeling confident and safe using the pathway, with only 28% participants having recently managed an FN patient.

Homecare and Discharge:
28.5% of participants were confident in arranging discharge follow-up and 54.5% were aware of the homecare eligibility checklist. Only 20% knew the correct information for the homecare assessment form.

Experience:
Responses suggested parents and carers are receptive to the homecare pathway and are often ‘thrilled to not have to stay in hospital’. Staff requested a teaching session to enhance their knowledge of the protocol.

Conclusion

While most respondents were aware the pathway exists, our survey demonstrates that many participants have little experience and confidence in using the pathway. In contrast, staff report parents/carers are supportive of the homecare protocol. As a result, the next steps are to empower staff to feel knowledgeable, confident and safe in using the homecare protocol with accessible teaching sessions.

Let’s clear the air on vaping

Carolyn Major — 2026-06-09

Objectives

Our aim was to support young people with vaping by empowering our paediatric team to explore vaping and smoking with them, provide information and signpost to further support.

Background

Vaping is widespread in young people and carries numerous physical and mental health risks, with unknown long-term effects.^1-3 There is a considerable environmental impact of disposable vapes. As per the Royal College of Paediatrics and Child Health (RCPCH), paediatricians should discourage vaping and be proactive in preventing uptake.⁴

Methods

We audited all admissions of secondary school age to the children’s ward for documented vaping or smoking status in the electronic medical records for a series of months, before and after our interventions.

We met with the local drug and alcohol service for young people and organised teaching with them to inform our team about the risks of vaping, the impact in our community and support available. Educational information was distributed amongst the paediatric team and posters were designed and displayed throughout the children’s ward and emergency department, which included a QR code for an information leaflet and details for the drug and alcohol service. ‘Vaping or smoking status’ was added to our safe handover checklist.

Results

At baseline, month A, 14% of young people admitted to the children's ward had a documented vaping or smoking status (Table 1). This doubled in month B, the month following the teaching session and was sustained in month C, three months later. In month D, after a rotation of resident doctors, there was a decline in the proportion of young people with a documented vaping or smoking status, despite our change to the handover checklist, but still an improvement from baseline.

Our findings were inconsistent with national data on vaping amongst young people; only two young people in the study disclosed vaping¹. This may mean that more needs to be done to help young people to feel comfortable discussing their vaping and smoking status.

Conclusions

Our project generated an increase in the proportion of young people being asked about vaping, creating opportunities for individual health interventions. However, there is still a need
for further improvement in this area. We plan to continue the education with support from the drug and alcohol service, provide information packs for young people, and incorporate a
reminder in the electronic medical record.

Clean air, healthy futures

Harry Apperley — 2026-06-09

Background

Air pollution is a critical issue affecting both health and the environment. Both the UN and the Royal College of Paediatricians and Child Health (RCPCH) assert that access to clean air is a basic human right, but it remains a central driver of health inequalities. Despite the myriad health risks, children and families often lack awareness of the health effects and strategies to address them. Paediatricians have a duty to close this knowledge gap. The RCPCH is well placed to harness young people’s voices in addressing this global challenge. Our work offers practical solutions on how clinicians can engage children and young people (CYP) to build knowledge and empower them through actionable advice.

Methods

A mixed methods approach with workshops, surveys and group discussions engaged 954 CYP across the UK in a variety of settings including mainstream and special educational needs schools, hospitals, and community spaces. Qualitative data was analysed thematically to explore CYP perceptions of air quality and awareness of health consequences. Quantitative insights from structured questionnaires complement these findings.

Results

82% of CYP believed there was a connection between air pollution and health problems, identifying respiratory issues as the primary impact. However, they demonstrated limited understanding of how to mitigate risks. 58% had learnt about air quality in schools, but only a minority had discussed air quality with healthcare professionals, despite viewing them as trusted sources of advice. 77% said that it was important for CYP views on improving air quality to be listened to by people in power.

Conclusions

The voices of young people offer a unique and vital contribution. Their desire for education and advocacy for clean air present a timmely opportunity for clinicians and policymakers to rethink how air pollution is addressed in clinical practice. Incorporating young people’s voices is crucial, and clinicians have a central role to play in translating concerns into practical action. The RCPCH has co-created resources for workforce education, as well as policy documents promoting local and global advocacy. Clinicians should be equipped to engage patients and families in conversations around air pollution as part of routine consultations. As one young person poignantly expressed, “Clean air is not a privilege, it’s a right we all deserve for our health and our future.”

The London Trainee Network Conference 2024 – Medicine of the Future

Olivia Stredder — 2026-06-09

Objective

To improve professional and social connections between trainee doctors of different specialties and provide an interesting day which helps build morale and improve wellbeing.

Background

Funded by NHS England, the London Trainee Network is formed by a group of trainees representing the various medical specialties in London, who are passionate about improving post-graduate medical education and training for their peers. In the modern medical world burnout and low morale are pressing issues (Karageorgos et al 2026, RCPCH 2024, HEE 2017)) and our organisation aims to support and motivate trainees. Involving trainees from different specialties allows attendees to learn from the way different specialists approach clinical and personal challenges. Cross-specialty events allow colleagues from different branches of medicine to share experiences, career trajectories and philosophies of practice and to facilitate engagement and connection between resident doctors.

Methods

The London Trainee Network hosted its third annual conference entitled: Medicine of the Future. The conference was hosted at the Kia Oval, and was free to all participants. It included a hot lunch as well as snacks and drinks throughout the day. The programme included talks on leadership, medicine and work/life balance, transgender medicine, assisted dying and palliative care, doctors’ pay and how to check your payslip and a panel discussion on artificial intelligence in medicine. There were also workshops on pensions, insurance and maternity, yoga, digital health and the path to PhD as well as a poster competition. Feedback was collected after the conference via a QR code linking to a Google form. Filling in the survey was required to access a certificate of attendance.

Results and conclusions

The conference was attended by 109 delegates including residents at all stages of training (foundation, core and speciality) and clinical fellows. We received feedback from 57 people who all rated the conference overall good or above, with 54.4% rating it excellent and 40.4% rating it very good. Feedback was collated on each individual talk or workshop, and there was an opportunity to comment on the whole day, both to offer positive feedback and suggestions for improvement. Answering the question ‘What did you like about this event?’, at least 10 comments mentioned the variety of practical and relevant topics and 20 mentioned excellent organisation. Other comments mentioned the cross-specialty element as particularly positive, as well as the food and venue. As suggestions for improvement, three comments suggested sharing slides and learning points after the conference and at least three people mentioned that they would have liked more of an interactive element to foster connection between delegates. Individual comments also suggested more talks related to building a portfolio, and one suggested offering specialty specific sessions. Despite this 100% of delegates said they would recommend it to a friend.

AI for Paediatricians

Alexander Brown — 2026-06-09

Objectives

To describe a novel training approach ('AI for Paediatricians') developed and run by the London School of Paediatrics Innovation Group.

Background

AI is a rapidly evolving subject that has gained increasing attention in the last five years. There is great excitement about clinical applicability of AI tools, but also significant caution.

Clinicians, many of whom have had no training in the basics of AI, will be at the forefront of using, appraising, and overseeing the implementation of these tools. Without a firm understanding of the topics, they may struggle, resulting in deployment of unsafe or ineffective solutions, or undue hesitancy in adopting novel technologies that may have great potential for benefitting our patients.

Paediatrics faces particular challenges in adopting AI. Therefore, there is an even greater need to support paediatricians in understanding this field.

Methods

We developed a whole-day training programme, designed to educate clinicians about what AI is, how it works, and how it can go wrong. Our primary audience was resident paediatric doctors, although the day was open to participants from a variety of backgrounds.

Topics included the basics of AI; neural networks and large language models; how AI models are created; evaluation and appraisal of AI tools; how AI goes wrong; and post-marketing monitoring of AI tools. All the presenters were paediatric resident doctors with significant practical experience of clinical AI. We gathered pre-course feedback to characterise participants’ confidence and understanding around the topic of AI as applied to clinical medicine, and again after the course to assess the impact of the training.

Results

We found that participants, despite being self-selected as a group with an interest in AI, had low levels of confidence and understanding prior to the course. The training day significantly improved confidence and understanding of AI topics. Participants enjoyed the day, with a majority strongly agreeing that they would recommend the course to a friend/ colleague.

Conclusions

Training clinicians to understand and critically appraise novel AI technologies will be key to safe and timely use of such tools. Our training day was highly effective in addressing this need. Following feedback from participants, we will further refine the programme for the day, and we aim to run the next session in late 2025.

The impact of a new format of teaching newsletter in the general paediatric department – A multicentre QIP

Li Ying Goh — 2026-06-09

Objectives

Medical online newsletters have an established role in the continuing education of medical professionals. We aim to measure the impact of implementing of a new, accessible, compact weekly newsletter on the self-motivation, wellbeing, and supported learning of paediatric doctors in the general paediatric departments of 2 hospitals.

Methods

A regular easy-to-read newsletter was sent out weekly via email. This included a teaching timemetable, motivational quote, a section for health awareness days and links for further resources and the RCPCH curricula. The newsletter was implemented in the first hospital from March 2023, and carried on by a new rotation of doctors from September 2023. In the second hospital this started in September 2023. Recipients were surveyed at the end of rotations in March (at the second hospital) and September 2024 (at both hospital). Respondents were grouped into those receiving the newsletter between March- September 2023 in Epsom, after September 2023 in the first hospital, and after September 2023 in the second hospital.

Results

We received a total of 31 responses across 2 surveys. Of the 21 responses in the second survey in September 2024, 6 (28.6%) respondents were paediatric trainees (2 (9.5%) ST1-2; 4 (19%) ST3+), 6 (28.6%) were consultants, and 6 (28.6%) were clinical fellows surveyed across both sites. The remaining respondents were GP trainees and foundation doctors. We do not have the training stages breakdown for the first survey (n=10). Based on the feedback from all 31 respondents combined, 95.2% of respondents liked the format of the newsletter, 100% found it helpful to know the teaching schedule ahead of time, and 100% felt more motivated to attend because of this. Of the 21 respondents in the second survey, 57.1% of respondents in the second survey thought the motivational quote had a positive impact on team wellbeing with 19% replying maybe. When asked what else should be included in the newsletter, respondents suggested including subspecialty teaching sessions (61.9%), teams links for teaching sessions (52.4%), and MDT/ radiology meetings (42.9%). All respondents wanted it to continue for future rotations and 81% wanted other trusts to implement a similar teaching newsletter. Overall, 52.4% of respondents gave the newsletter the highest rating of 5 and the remaining 47.6% gave a rating of 4.

Conclusion

The newsletter was successfully implemented across trusts. Through our survey we have identified obstacles to distribution of the newsletter and collected constructive feedback which will be used to improve the newsletters at both sites. This project serves to further establish the role of newsletters and having structured training programmes in paedatric training in improving motivation and wellbeing.

Education in Paediatrics

Michelle D'Souza — 2026-06-09

Education in paediatrics is more than simple knowledge acquisition from reading a textbook or attending a lecture. It’s learning how to think under pressure in the middle of a resuscitation, how to explain a complex diagnosis to a terrified parent and how to advocate for a child who cannot speak up for themselves.

Teaching goes beyond the classroom, embedded into everyday practice, preparing the clinicians of the future. Singh et al. demonstrate exactly this with their educational programme preparing senior trainees for the daunting transition to consultant. Gluck et al. describe a targeted simulation programme to support residents to develop their communication skills in a psychologically safe environment, preparing them for those challenging clinical encounters.

Teaching can also support wellbeing and team morale. Goh et al. describe how an educational newsletter with resources and a motivational quote can facilitate learning and improve team wellbeing. As Madden-Hansle reflects on her transition from learner to educator, she describes how teaching in the clinical settng can break down barriers and help medical students to feel like part of the team, a reminder that education builds community as well as competence.

Finally we are reminded of the ever-changing landscape of clinical practice. Brown et al. describe a new training programme for paediatric residents to improve confidence and understanding of artificial intelligence, one example of how medicine continues to evolve. No matter how senior you become, paediatrics requires lifelong learning so that we can provide the best quality care for our patients and families.
