REGULATION 28:  REPORT TO PREVENT FUTURE DEATHS 

THIS REPORT IS BEING SENT TO: 

 1. 

   1. West Yorkshire Integrated Care Board (ICB), White Rose House, West Parade, Wakefield    
WF1 1LT    

CORONER 

I am Oliver Robert Longstaff, Area Coroner for the Coroner Area of West Yorkshire (East). 

CORONER’S LEGAL POWERS 

I make this report under paragraph 7, Schedule 5, of the Coroners and Justice Act 2009 and 
regulations 28 and 29 of The Coroners (Investigations) Regulations 2013. 

INVESTIGATION and INQUEST 

On 06 September 2024 I commenced an investigation into the death of Chloe Alicia Ellis who 
died on 03 September 2024 in Leeds General Infirmary.  The investigation concluded at the end 
of the Inquest on 09 June 2025.  The medical cause of death was 1a) Pulmonary Embolism; 1b) 
Endometriosis, Treated with Oral Contraceptive Pill.  

In summary, the narrative conclusion to the inquest was that, had a history of her oral 
contraceptive use been obtained when Chloe attended a local hospital Emergency Department 
on 31 August 2024, she would have been given anticoagulation medication and undergone 
tests that would have revealed the pulmonary embolism.  She would have received effective 
treatment for the pulmonary embolism and, on the balance of probabilities, would not have died 
three days later.

CIRCUMSTANCES OF THE DEATH 

4 

Chloe Ellis had been taking the Yasmin contraceptive pill to manage her endometriosis since 
September 2023.  

On 31 August 2024 she undertook an NHS 111 online assessment in which she reported chest 
and back pain and breathlessness and gave a history of her oral contraceptive use.  The 

 
  
 
 
  
 
 
 
 
  
 
 
 
 
 
  
 
 
 
 assessment algorithm advised her to attend a local Emergency Department, having concluded 
via the algorithmic process that she had a suspected pulmonary embolism.  The assessment 
algorithm did not tell Chloe herself that she had a suspected pulmonary embolism.  

The outcome of the NHS online assessment was not available to clinical staff at the Emergency 
Department at Dewsbury District Hospital where Chloe attended.  There, an inadequate history 
was obtained from her, in that she was not asked about her medication history and specifically 
about her use of oral contraception.  The inquest was informed of measures taken by the Mid 
Yorkshire Teaching NHS Trust in relation to that inadequate history taking, and no Reg 28 
report is being made in respect of it.  

Chloe was diagnosed with a viral illness and discharged.  She collapsed at home on 03 
September 2024 and, despite the best efforts of attending paramedics and clinicians at Leeds 
General Infirmary, she died later that day.   

CORONER’S CONCERNS 

During the course of the Inquest the evidence revealed matters giving rise to concern.  In my 
opinion there is a risk that future deaths will occur unless action is taken.  In the circumstances it 
is my statutory duty to report to you. 

The MATTERS OF CONCERN are as follows.  – 

(1) The inquest was told that it is possible for the outcomes of NHS 111 online assessments to 
be made accessible to Emergency Department clinicians, and that the decision whether or not 
to commission that accessibility in a particular hospital rests with the relevant Integrated Care 
Board.   

5 

(2) The inquest was told that the West Yorkshire Integrated Care Board has not commissioned 
accessibility to NHS 111 online assessments for the Mid Yorkshire Teaching NHS Trust.   

(3) If the NHS online assessment completed by Chloe had been available to the relevant 
clinicians at Dewsbury District Hospital, her history of oral contraceptive use and the suspicion 
of a pulmonary embolism would have been visible to them.   

(4) The availability of NHS 111 online assessments to clinicians in Emergency Departments 
may assist in the obtaining of a full history and may act as a failsafe against inadequate history 
taking in Emergency Departments.      

ACTION SHOULD BE TAKEN 

6 

In my opinion action should be taken to prevent future deaths and I believe you or your 
organisation have the power to take such action.

West Yorkshire (East) 

Via email: 

Dear Mr Longstaff, 

Thank you for your letter of 13th June 2025 in relation to the Regulation 28 report to 
prevent future deaths following the inquest into the death of Chloe Ellis. This was 
issued to the West Yorkshire Integrated Care Board (WYICB), White Rose House, 
West Parade, Wakefield, WF1 1LT. 

I would like to offer my sincere condolences to Chloe’s family on behalf of the NHS 
West Yorkshire Integrated Care Board. I am sorry for their loss and for the 
circumstances surrounding Chloe’s death. 

You raised the following Matters of Concern: 

•  The inquest was told that it is possible for the outcomes of NHS 111 online 

assessments to be made accessible to Emergency Department (ED) 
clinicians, and that the decision whether or not to commission that 
accessibility in a particular hospital rests with the relevant Integrated Care 
Board.  

•  The inquest was told that the WYICB has not commissioned accessibility to 
NHS 111 online assessments for the Mid Yorkshire Teaching NHS Trust 
(MYTT).  
If the NHS online assessment completed by Ms Ellis had been available to the 
relevant clinicians at Dewsbury District Hospital, her history of oral 
contraceptive use and the suspicion of a pulmonary embolism would have 
been visible to them.  

• 

•  The availability of NHS 111 online assessments to clinicians in EDs may 
assist in the obtaining of a full history and may act as a failsafe against 
inadequate history taking in EDs. 

I will respond to these points and hope to provide assurance around actions that 
WYICB is taking as a result.  

               
 
 
 
 
 
 
 
 111 Online Assessments and Data Sharing 

Timely access to comprehensive medical records — including NHS 111 online 
assessments — is an important contributor to supporting effective and safe clinical 
assessments within Emergency Departments (EDs). At the time of the case involving 
Chloe, no Emergency Departments across West Yorkshire had access to NHS 111 
Online assessment data. This meant that the assessment information could not be 
shared with Emergency Department clinicians.  

At present, NHS 111 Online is commissioned nationally by NHS England (NHSE) 
and not directly by the West Yorkshire Integrated Care Board (WYICB). When a 
patient completes an NHS 111 Online assessment, the system advises them on the 
most appropriate local service to attend. We have been considering options for the 
development of “interoperable” systems locally that can routinely share data, 
including these assessments, between NHS111 and EDs.  

However, there is now a national solution in development which is designed to 
enable the safe, structured transfer of such information across systems. This is 
called the Booking and Referral Standard (BaRS). Our approach will be to use the 
BaRS in West Yorkshire. 

Implementation of the Booking and Referral Standard (BaRS) 

BaRS is a national interoperability standard that enables the secure sharing of 
patient information, supporting both clinical care and operational processes. It is 
expected to enhance patient safety, especially within urgent and emergency care, by 
ensuring essential clinical information is available to clinicians in real-time. 

The national development and implementation of BaRS was first signalled in the 
2022 Plan for Digital Health and Social Care. NHS England has recently confirmed 
that BaRS is now being rolled out to support urgent and emergency care pathways.  

Adoption of BaRS is the responsibility of individual NHS trusts and their suppliers. 
However, compatibility with many existing NHS IT systems — such as Symphony, 
currently used within Mid Yorkshire Teaching Trust (MYTT) — is not yet in place and 
still under development. WYICB is working actively with national and local partners 
to facilitate this integration. It is anticipated that NHS 111 Online assessment data 
could be available to EDs in West Yorkshire by March 2026. 

Broader Efforts to Improve Access to Clinical Information 

In addition to supporting BaRS implementation, WYICB is also promoting access to 
medical histories through the Yorkshire and Humber Care Record, which offers 
clinicians improved visibility of a patient’s broader health information. This is another 
important step towards more joined-up and informed care. Medical history 
information is shared via the Yorkshire and Humber Care Record, providing 

 
 clinicians with a holistic view of a patient’s health. This comprehensive information 
enables clinicians to make a more informed assessment. 

We are aware that the inquest into the death of Chloe was informed of actions being 
taken by Mid Yorkshire Teaching Trust to improve the assessment of patients 
presenting at the Emergency Department. WYICB is committed to working in close 
partnership with MYTT to further support these improvements. 

I hope this letter provides reassurance of our commitment to improving both patient 
safety and interoperability between services.  We will continue to engage with 
colleagues from both MYTT and NHSE to support continued improved 
interoperability and transfer a critical patient information.  

Should you have any further questions, or need for clarification please do not 
hesitate to contact me again. 

Yours sincerely,  

Chief Executive NHS West Yorkshire Integrated Care Board  
West Yorkshire Health and Care Partnership
