Dear Coroner, Re: Regulation 28 Report to Prevent Future Deaths – Evelyn Rae Le Masurier- O’Sullivan who died on 17th April 2022.

Thank you for your Report to Prevent Future Deaths (hereafter “Report”) dated 26th November 2025 concerning the tragic death of Evelyn Rae Le Masurier-O’Sullivan (“Evie”) on 17th April 2022. In advance of responding to the specific concerns raised in your Report, I would like to express my deep condolences to Evie’s family and loved ones. NHS England is keen to assure the family and yourself that the concerns raised about Evie’s care have been listened to and reflected upon.

Your Report raised the concern that most NHS Trusts do not provide in-house training to their agency staff as they are not provided with funding to train them. You were concerned that there is a training gap for temporary / agency staff provided by “On- Framework” suppliers, particularly in relation to eliciting parental concerns about a baby’s wellbeing at postnatal contacts.

The training of agency staff is a local Trust level issue and not something that NHS England mandates nationally. The Maternity Incentive Scheme (MIS) safety action 8 states ‘It is the responsibility of the employing agency to provide training for staff, it is the responsibility of the Trust to ensure that all agency staff have met minimum training requirements before working in the Trust. The Safe, Sustainable and Productive Staffing resource highlights that “All temporary staff should receive local training and induction, so they are familiar with how the organisation works.”

The specifics of eliciting parental concerns about a baby’s wellbeing at postnatal contacts falls under fitness to practise and regulation, as all midwives should have these skills. A number of standards within the Standards of Proficiency for Midwives guidance, published by the Nursing & Midwifery Council (NMC), relate to eliciting parental concerns regarding neonatal wellbeing during postnatal contacts. Specifically, the following two standards reflect what a midwife should be competent National Medical Director NHS England Wellington House 133-155 Waterloo Road London SE1 8UG

to do at the point of registration and must maintain as a requirement of the regulator (NMC):

• 6.15 when assessing, planning, and providing care include the woman’s own self-assessment and assessment of her newborn infant’s health and wellbeing, and her own ability and confidence in regard to self-care and care for her newborn infant
• 6.59 conduct ongoing assessments of the health and wellbeing of the newborn infant, involving the mother and partner as appropriate and providing a full explanation.

Through the process of regulatory revalidation, each registrant (midwife) must meet specific requirements to ensure they remain fit to practice, to maintain their registration.

Croydon Health Services NHS Trust has provided NHS England’s London regional team with details of the action plan they have completed as a result of this Report and the improvements they have made as a result. The Trust has advised that key message would be sent to all staff including NICE sepsis management guideline and audits will be completed regarding antibiotics compliance, reviewing the quality of resuscitation documentation, as well as audits to ensure that new starters attend PROMPT training within one month of recruitment.

I would also like to provide further assurances on the national NHS England work taking place around the Reports to Prevent Future Deaths. All reports received are discussed by the Regulation 28 Working Group, comprising Regional Medical Directors, and other clinical and quality colleagues from across the regions. This ensures that key learnings and insights around events, such as the sad death of Evie, are shared across the NHS at both a national and regional level and helps us to pay close attention to any emerging trends that may require further review and action.

Thank you for bringing these important patient safety issues to my attention and please do not hesitate to contact me should you need any further information.

Report sections

Investigation and inquest
On 23 February 2023, an inquest was opened, and an investigation commenced, into the death of Evelyn Rae Le Masurier-O’Sullivan (“Evie”), who died 23 hours after she was born.

The investigation concluded at the end of the inquest, which was heard over 4 days between 9 and 12 September 2025 and my conclusion was handed down on 16 October 2025.

The medical cause of death was:

1a. Disseminated Intravascular Coagulopathy and Persistent Pulmonary Hypertension of the Newborn. 1b. Sepsis.

The conclusion was as follows:

At around 00:06 on 17 April 2022, when she was less than 10 hours old, Evie became unwell with signs of respiratory distress caused by an infection. A vaginal swab of Evie's mother after her death tested positive for Group B Streptococcus, which was the cause of Evie's infection and the neonatal sepsis which she went on to develop. Evie died as consequence of Disseminated Intravascular Coagulation and Persistent Pulmonary Hypertension of the Newborn, which were secondary to the neonatal sepsis.

Although Evie's mother was seen by a member of the midwifery team at around 00:30 and by a midwife at around 02:30, they did not elicit concerns Evie's parents had about Evie's crying and breathing, and nor did they afford an opportunity for these concerns to be shared. This led to an absence of neonatal assessments being carried out and absence of escalation to the hospital's neonatal team, which contributed to the death. Evie's death was also contributed to by the delay between 08:00 and 10:00 in administering antibiotics. Evie's death was contributed to by neglect.
Circumstances of the death
Evie was born at 14:17 on 16 April 2022 at Croydon University Hospital by a category 3 emergency caesarean section. Evie was born in good condition with her Apgar scores being normal at 1, 5 and 10 minutes after her birth. There were no known risk factors for Group B Streptococcus or sepsis.

In the early hours of the following morning, at or around 00:06 on 17 April 2022, whilst on the post-natal ward, Evie was becoming unwell and began to display symptoms of respiratory distress in the form of an abnormal sound known as grunting. These were the first signs that she had an infection.

Although Evie's mother was seen by a member of the midwifery team at around 00:30 and a midwife at around 02:30, those staff members did not elicit concerns Evie's parents had about Evie's crying and breathing, and nor did they afford an opportunity for these concerns to be shared.

At around 07:00 on 17 April 2022, Evie was observed with signs of respiratory distress, including chest recessions, nasal flaring and some slight grunting. After a neonatal review, she was admitted to the hospital's neonatal unit. The working diagnosis at that time was that Evie was suffering from sepsis. Although antibiotics to treat the suspected sepsis should have been administered within the hour, they were not administered until 10:00.

Evie initially stabilised on the neonatal unit. However, she went on to have an acute deterioration with clinical evidence of pulmonary hypertension and became difficult to oxygenate. Thereafter Evie went on to have a pulmonary haemorrhage and disseminated intravascular coagulation and went into cardiac arrest. Advanced life support resuscitation was performed and although return of spontaneous circulation was achieved on three occasions, Evie could not be stabilised and died at 14:06 on 17 April 2022.
