Coroner Exposes Critical NHS 111 Failure in Toddler's Sepsis Death
An NHS 111 operator failed to recognise that a three-year-old boy who was 'turning blue' and 'fighting for breath' was in a life-threatening situation before his tragic death from sepsis, a coroner has revealed. Theo Tuikubulau died in July 2022 after multiple systemic failings by Derriford Hospital in Plymouth and the wider NHS, as heard during an inquest into his death.
Gradual Deterioration and Missed Emergency Signs
Theo had been gradually getting sicker in the lead-up to his death, suffering from a high temperature, flu-like symptoms, breathing difficulties, and an inability to eat or drink. His mother, Kayleigh Kenneford, called NHS 111 just before 11pm on July 7, 2022, but due to a 'two-tier response' in how NHS 111 and 999 assess lips turning blue, it took 90 minutes for him to be taken to hospital.
Louise Wiltshire, assistant coroner for the County of Devon, Plymouth and Torbay, issued a prevention of further death notice to NHS England following the inquest. She highlighted that ambulance response times varied dangerously depending on whether 999 or 111 was called, creating an inconsistent emergency assessment system.
Systemic Flaws in Emergency Triage Protocols
In the UK, 999 is designated for life-threatening or immediate emergencies, while 111 provides urgent, non-life-threatening medical advice. However, NHS England confirmed in its response that the NHS Pathways system, used by NHS 111 services and over half of England's 999 telephony services, did not recognise 'lips turning blue' as a life-threatening emergency.
This discrepancy stems from the use of different triage tools: MPDS is a rapid triage tool for 999 emergency calls, whereas NHS Pathways is a clinical assessment system used for both 999 and 111 services. After a review, NHS England acknowledged 'variation between the two triage systems with regards to respiratory distress in children under five, specifically in relation to the management of declared cyanosis (where the patient's skin or lips have turned blue or grey).'
Contradictory Emergency Responses and Hospital Discharge
Just one day before his death, Theo had been taken to hospital by ambulance after his mother called 999, with the South West Ambulance Service (SWAS) grading it as a category one emergency—the highest priority for life-threatening cases. However, hours later, the toddler was discharged from Derriford Hospital with a suspected respiratory infection, with a doctor reportedly saying he would get worse before improving.
When Theo deteriorated further, Ms. Kenneford turned to NHS 111 after being 'fobbed off' by the hospital helpline. The 111 service operated on a different system than the 999 service in Devon, resulting in a less urgent category two ambulance being dispatched. The head of emergency operations at SWAS testified that if his team had answered the call, it would have been graded as category one.
Coroner's Warning of a National Two-Tier System
Ms. Wiltshire stated that this difference 'appears to create a two-tiered system of assessment and ambulance categorisation in the Devon area (and potentially nationally).' She wrote: 'It appears that similar breathing complaints requiring urgent medical attention will result in a different ambulance disposition depending on whether the call is triaged by MDPS (used by the 999 provider in Devon) or NHS Pathways (used by the 111 provider in Devon).'
Following the inquest, she wrote to both organisations responsible for the assessment systems to establish why such a critical discrepancy exists. An NHS spokesperson responded: '999 and 111 services use clinical triage systems to identify life-threatening symptoms such as breathing difficulties at speed so patients receive the right response as quickly as possible, and calls are escalated immediately if new information comes to light. We continually work with providers to ensure the response across both systems remains consistent for patients, and we will respond to the findings in due course.'
This case underscores urgent concerns about the consistency and reliability of emergency medical responses in the NHS, particularly for vulnerable young children with life-threatening conditions like sepsis.
