REPORT TO PREVENT FUTURE DEATHS REGULATION 28 OF THE CORONERS (INVESTIGATIONS) REGULATIONS 2013 Please do not include any living persons’ names in this document, in accordance with the Chief Coroner’s PFD Publication Policy (2026). 1. CORONER I am Sonia Hayes, Area Coroner, for the coroner area of Essex. 2. DATE OF REPORT 28 MAY 2026 3. 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. 3. THIS REPORT IS BEING SENT TO 1. Chief Executive of Mid & South Essex NHS Foundation Trust 2. NHS England 3. Integrated Care Board – Mid & South Essex You are under a duty to respond to this report within 56 days of the date of this report, namely by 23 JULY 2026. I, the coroner, may extend the period if an appropriate application is made. 4. YOUR RESPONSE Your response must contain details of action taken or proposed to be taken, setting out the timetable for action. Otherwise, you must explain why no action is proposed. I have a duty to send a copy of your response to the Chief Coroner. In accordance with the Chief Coroner’s Publication Policy, you should send me any representations regarding publication of your response. These representations should be made at the same time as the response is provided. I will pass any representations received to the Chief Coroner for a decision. Please note any links to webpages included in the response will not be checked for sensitive information prior to publication, as the information is already online. The names of those who do not respond to PFD reports are regularly published on the Chief Coroner’s webpages Non-responses to Prevention of Future Death (PFD) reports - Courts and Tribunals Judiciary. 5. SUMMARY OF CORONER’S CONCERN 1. Lacey Heath was a clinically complex patient who following her Prosthetic Aortic Valve Replacement with Aortic graft requiring lifelong anticoagulation to mitigate known risks associated with thrombosis. 2. Clinicians struggled to achieved therapeutic anticoagulation for Lacey ad combinations of therapy were tried. Acenocoumarin as an alternative led to very high INR readings. The GP referred Ms Heath back to the hospital due to the complexity of the case. 2 2 3. Ms Heath’s experienced clinical team recommended an at home monitor be utilised to attempt to achieve a therapeutic range given the complexity of her dosing requirements, so daily readings could be taken. The NICE Guidance Anticoagulation -Oral last updated August 2025 states that at-home monitor is not funded by the NHS, and Ms Heath was on a low income and was prohibited from using this tool to attempt to achieve a therapeutic range with appropriate oral medications. 4. Ms Heath was at increased risk of developing complications with her INR results, and this was not escalated and her clinic appointment with INR testing remained the same. 5. Hospital Medical records were not compliant with the requirements of healthcare regulators and led to a lack of appreciation of Ms Heath’s concerns, the complexity of her case and the ongoing risk to Ms Heath. Staff use an electronic platform to record INR and medication dose and have no other place to record anticoagulation records within the anticoagulation clinic. 6. 7. ACTION SHOULD BE TAKEN In my opinion unless action is taken to address the above concerns then there is a significant risk of future deaths, and I believe each of you have the power to take such action. INVESTIGATION AND INQUEST On 21 February 2025, I commenced an investigation into the death of Lacey Carole Anne HEATH, aged 34 years that concluded on 13 May 2026. The medical cause of death was: 1a Prosthetic Aortic Valve Thrombosis with Sub-Therapeutic Anti-Coagulation 2 Turners Syndrome Lacey Carole Anne HEATH died on 16 February 2025 at Lynfields, London Road, Witham of Prosthetic Aortic Valve Thrombosis with Sub-Therapeutic Anti-Coagulation en-route following a collapse at home. Miss Heath had Turner’s Syndrome and had a bicuspid valve and was at higher risk of developing cardiac problems. Miss Heath underwent successful surgical replacement of her Aortic Valve, aortic root and ascending aorta in May 2019 and was prescribed anticoagulation. Miss Heath was a medically complex patient with warfarin resistance. There was difficulty maintaining anticoagulation within a therapeutic range that was managed by the local hospital that were not resolved with medication changes. In January and February 2025 anticoagulation was noted to be sub-therapeutic. Miss Heath was found on the morning of 16 February 2025 with rapid respiration and unresponsive. Miss Heath went into cardiac arrest en-route to hospital and ambulance crew stopped and commenced resuscitation with escalation to critical care support. HEMS continued with advanced life support upon arrival, but Miss Heath had complete stenosis of her mechanical valve with thrombosis that caused the cardiac arrest that was irreversible Conclusion Miss Heath was at significant risk of developing thrombus on her mechanical aorta valve as a recognised complication of necessary medical treatment. The risk increased when required anticoagulation was sub-therapeutic, and that contributed to her death. 8. CIRCUMSTANCES OF DEATH Lacey Carole Anne HEATH died on 16 February 2025 at Lynfields, London Road, Witham of Prosthetic Aortic Valve Thrombosis with Sub-Therapeutic Anti-Coagulation en-route following a collapse at home. Miss Heath had Turner’s Syndrome and had a bicuspid valve and was at 3 3 higher risk of developing cardiac problems.

HEMS continued with advanced life support upon arrival, but Miss Heath had complete stenosis of her mechanical valve with thrombosis that caused the cardiac arrest that was irreversible 9. CORONER’S CONCERNS During the course of the inquest I heard evidence giving rise to concern. In my opinion there is a risk that future deaths could 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. Ms Heath was noted to be warfarin resistant and alternative medication regimes were not successful in keeping Ms Heath within a therapeutic range for her required lifelong requirement to have anticoagulation to prevent a significant risk of death. The GP and hospital clinicians trailed different combinations of appropriate therapy which included additional injections when required. This was not considered to be clinically appropriate long-term. 2. Due to the complexity of her case, Ms Heath’s anticoagulation was under the care of the acute hospital team. Alternative anticoagulation medication had resulted in high INR readings and significant risks associated with bleeding. 3. Ms Heath’s experienced clinical team did not consider that there had been a sufficient trial of Warfarin and recommended at-home monitoring to permit daily readings to be taken to manage the significant risks associated with anticoagulation and to find an individualised dose for Ms Heath. Clinicians were not concerned about medication non-compliance and that the difficulties were clinical. 4. Ms Heath could not afford to fund the at home monitor as this was financially prohibitive for her being on a low income. The monitor was expensive and there is no obligation for General Practitioners to fund the testing strips and incidentals required to facilitate testing. As this would be a lifelong commitment for a woman who was only 34 years-old, Ms Heath was not able to take the advice of her expert clinical team and was compelled to have alternative prescribing that was not successful in keeping her INR within therapeutic range. 5. No application for funding was made on behalf of Ms Heath by the Trust nor was this explained to Ms Heath who a very quiet, shy lady who always relied on her very loving family to assist her with appointments and could not advocate for herself. There was no consideration if Ms Heath had any learning difficulties and it was noted that there was developmental delay in her medical records. Evidence at the inquest was Ms Heath experienced this as clinicians not caring about her and she became very despondent about the failure to achieve a therapeutic range. 4 4 6. Ms Heath did not manage to achieve a therapeutic INR for a protracted period of time putting her at increased risk of developing complications and did have a medical review or a haematology referral. 7. There was an absence of appropriate medical records recorded for Ms Heath to understand her clinical presentation other than very basic information on the INR platform on INR results and medication dose. Evidence was these records are not compliant with the requirements of healthcare regulators and led to a lack of appreciation of Ms Heath’s concerns and the complexity of her case. One entry stated Ms Heath had been “unwell” with no clarification or further information on what the problem was and/or how this may have impacted on her condition. 10. COPIES AND PUBLICATION OF THIS REPORT I have a duty to send a copy of my report to every Interested Person who in my opinion should receive it. I also may send a copy of the report to any other person who I believe may find it useful or of interest. I can confirm I have sent the report to: 1. Care Quality Commission I also have a duty to send a copy of the report to the Chief Coroner. You may make representations to me, the coroner, about the publication of the contents of this report in line with Chief Coroner’s PFD Publication Policy (2026). Any representations will be sent to the Chief Coroner alongside the report. Please refer to box 4 above for additional information relating to the publication of reports and responses. SIGNATURE 5 5

Dear Ms Hayes,
Regulation 28 Report to Prevent Future Deaths – Miss Lacey Carol Anne Heath
I write further to your Prevention of Future Deaths Report, dated 28 May 2026, following
the conclusion of the Inquest touching on the death of Miss Heath.
We have considered your concerns and now set out our formal response to each matter
using your numbering as follows.
Matters of Concern
1. Ms Heath was noted to be warfarin resistant and alternative medication regimes
were not successful in keeping Ms Heath within a therapeutic range for her
required lifelong requirement to have anticoagulation to prevent a significant
risk of death. The GP and hospital clinicians trailed different combinations of
appropriate therapy which included additional injections when required. This
was not considered to be clinically appropriate long-term.
We recognise the importance of clinically appropriate plans being in place for our
patients. Therefore, we are implementing a high-risk anticoagulation pathway for
patients with persistent sub-therapeutic INR, suspected warfarin resistance, complex
anticoagulation requirements or repeated instability despite appropriate dose
adjustment.
The pathway will define criteria for senior clinical review, frequency of INR testing,
escalation thresholds and documentation requirements. This is due for completion by
the end of July 2026.
Patients with prolonged sub-therapeutic INR or complex anticoagulation needs will
be identified promptly and receive documented senior review. There will be an
approved pathway, staff communication, sample audit of high-risk cases and
evidence of escalation decisions recorded in the clinical record.
9
To maintain oversight and sustainability, the divisional governance team will
undertake a monthly audit of high-risk anticoagulation cases for the first three months
following implementation; thereafter there will be a quarterly audit.
Any issues detected in the audits will be reported through Pathology Governance
group and Broomfield Quality and Safety Hospital Group. Exception reporting at the
site level feeds up directly into trust-wide board ensuring oversight at a Senior
Leadership Level.
2. Due to the complexity of her case, Ms Heath’s anticoagulation was under the
care of the acute hospital team. Alternative anticoagulation medication had
resulted in high INR readings and significant risks associated with bleeding.
By the end of August 2026, we will have conducted a complete review of the
anticoagulation service escalation process for complex patients under hospital care.
We plan to introduce a documented requirement for complex cases including high INR
readings, bleeding risk, recurrent instability or failed alternative regimes to be reviewed
by a senior clinician and, where appropriate, haematology. This will establish a clear
escalation route for complex anticoagulation patients.
An updated standard operating procedure will be devised to reflect this approach,
which will include clearly defined senior review criteria.
Communication of the new process will be undertaken will all anticoagulation staff.
There will be a quarterly governance audit of complex anticoagulation cases and
escalation of any compliance concerns.
Any audit exceptions will be reviewed through the hospital site governance assurance
groups, and appropriate actions will be assigned where documentation or escalation
is incomplete or below the expected standard.
3. Ms Heath’s experienced clinical team did not consider that there had been a
sufficient trial of Warfarin and recommended at-home monitoring to permit
daily readings to be taken to manage the significant risks associated with
anticoagulation and to find an individualised dose for Ms Heath. Clinicians were
not concerned about medication non-compliance and that the difficulties were
clinical.
By the end of September 2026, a robust process for home INR monitoring will be in
place. Prior to home monitoring proceeding, we will conduct a detailed assessment
of patient suitability, any training needs, equipment requirement, general support and
governance, and follow-up arrangements as necessary. This new process will ensure
that decisions to recommend, decline or defer self-testing are clearly recorded with the
rationale, and always discussed with the patient and, if possible, their family or carers.
10
4. Ms Heath could not afford to fund the at home monitor as this was financially
prohibitive for her being on a low income. The monitor was expensive and there
is no obligation for General Practitioners to fund the testing strips and
incidentals required to facilitate testing. As this would be a lifelong commitment
for a woman who was only 34 years-old, Ms Heath was not able to take the
advice of her expert clinical team and was compelled to have alternative
prescribing that was not successful in keeping her INR within therapeutic
range.
By the end of September 2026 we will have a process for escalating cases where
recommended anticoagulation monitoring equipment or consumables may be
clinically required but financial barriers are identified. This will include signposting to
available funding routes, individual funding consideration, charitable support or
commissioner discussion where applicable.
Where financial barriers for clinically recommended monitoring are identified, they will
be escalated and documented. We plan to introduce funding and escalation guidance
that will be communicated to relevant staff. To ensure the new process is working
effectively, we plan to complete audits of funding applications.
5. No application for funding was made on behalf of Ms Heath by the Trust nor
was this explained to Ms Heath who a very quiet, shy lady who always relied on
her very loving family to assist her with appointments and could not advocate
for herself. There was no consideration if Ms Heath had any learning difficulties
and it was noted that there was developmental delay in her medical records.
Evidence at the inquest was Ms Heath experienced this as clinicians not caring
about her and she became very despondent about the failure to achieve a
therapeutic range.
By the end of October 2026, we plan to introduce a prompt within the high-risk
anticoagulation pathway requiring clinicians to consider whether the patient may need
additional communication support, family/carer involvement, reasonable adjustments
or advocacy where records or presentation suggest vulnerability, developmental
delay, difficulty self-advocating or reduced understanding of risk.
This will ensure that patients who may have additional communication or support
needs are recognised and supported in risk discussions and decision-making. This will
be by way of a pathway prompt, staff briefing, audit of high-risk cases for
documentation of support needs, family/carer involvement and agreed follow-up plans.
The effectiveness of this prompt and pathway will be monitored by the Patient
Experience and Learning Disability teams and reported to the Pathology Governance
group.
11
6. Ms Heath did not manage to achieve a therapeutic INR for a protracted period
of time putting her at increased risk of developing complications and did not
have a medical review or a haematology referral.
A defined trigger will be set for medical review and/or haematology referral when a
patient INR remains outside therapeutic range for a prolonged period; when repeated
appointments are not attended during a high-risk period; or when treatment instability
persists despite appropriate intervention. This will include a requirement for
documented clinical rationale where referral is not made.
This will allow patients with prolonged poor INR control to receive timely medical
review and specialist input where indicated.
The referral and escalation criteria will be updated along with a referral log, clinical
record audit and governance review of any cases breaching trigger thresholds.
7. There was an absence of appropriate medical records recorded for Ms Heath to
understand her clinical presentation other than very basic information on the
INR platform on INR results and medication dose. Evidence was these records
are not compliant with the requirements of healthcare regulators and led to a
lack of appreciation of Ms Heath’s concerns and the complexity of her case.
One entry stated Ms Heath had been “unwell” with no clarification or further
information on what the problem was and/or how this may have impacted on
her condition.
We are reviewing documentation standards within the anticoagulation service, and we
will implement a structured clinical note template for contacts, missed appointments,
patient-reported symptoms such as “unwell”, risk discussions, escalation decisions,
advice given and follow-up plan by the end of October 2026. This will explore system
functionality for persistent alerts or pinned critical risk information.
Clinical records will show clear evidence of the patient’s presentation, risks, advice,
escalation and follow-up. Critical risk information will then remain visible to staff
reviewing the case. There will be an approved note template, staff briefing, sample
documentation audit and outcome of clinical system review.
Monthly documentation audits will be undertaken for the first three months after
implementation, followed by quarterly intervals. Results and improvement actions will
be monitored through the Pathology Governance group and included in service quality
reports.
We are currently in the process of introducing a new single electronic patient record
(‘EPR’) system across our trust. This EPR will replace/integrate with current systems
services in all areas and will be for all our hospital sites.
12
This system will provide real-time and accurate information on a patient’s history to
support clinical decision making. Clinicians will have the ability to add and access
information to support quicker and personalised care for our patients, reducing the
need for paper-based processes and multiple systems.
The system is currently in its testing stage, expected to run through the remainder of
the year. As per current timelines, the system is expected to go live in June 2027.
Once established, the addition of the new EPR will be twofold:
1. The observations will be in the new EPR for all encounters across the trust from
the date it goes live
2. All new electronic notes will be visible within the notes
In the interim we will use our current INR monitoring system, INRstar, to conduct INR
checks.
Following implementation of the new EPR there will be further consideration as to its
use and its suitability and combability.
If I can assist any further with these matters, please do not hesitate to contact me.
Yours sincerely,
Chief Executive
Mid and South Essex NHS Foundation Trust

Dear Ms Hayes,
Re: Regulation 28 Report to Prevent Future Deaths – Lacey Carole Anne Heath
who died on 16th February 2025.
Thank you for your Report to Prevent Future Deaths (hereafter “Report”) dated 28th
May 2026 concerning the death of Lacey Carole Anne Heath on 16th February 2025.
In advance of responding to the specific concerns raised in your Report, I would like
to express my deep condolences to Ms Heath’s family and loved ones. NHS England
is keen to assure the family and yourself that the concerns raised about Ms Heath’s
care have been listened to and reflected upon.
Your Report raises the following concerns:
1. Although Ms Heath’s experienced clinical team recommended an at home
monitor be utilised to attempt to achieve a therapeutic INR range due to the
complexities of her case, NICE Guidance on anticoagulation states that at home
monitor is not funded by the NHS and there is no obligation for General
Practitioners to fund the testing strips and incidentals required to facilitate
testing. This means patients, such as Ms Heath who was on a low income, are
prohibited from using this tool to attempt to achieve a therapeutic range with
appropriate oral medications.
2. No application for funding was made on behalf of Ms Heath by the Trust nor was
this explained to Ms Heath. There was no consideration if Ms Heath had any
learning difficulties and it was noted that there was developmental delay in her
medical records.
3. Ms Heath was at increased risk of developing complications with her INR results,
but this was not escalated and so her clinic appointment with INR testing
remained the same.
4. Hospital Medical records were not compliant with the requirements of healthcare
regulators and led to a lack of appreciation of Ms Heath’s concerns, the
complexity of her case and the ongoing risk to Ms Heath. Staff used an
electronic platform to record INR and medication dose and have no other place
to record anticoagulation records within the anticoagulation clinic. Evidence was
these records are not compliant with the requirements of healthcare regulators
and led to a lack of appreciation of Ms Heath’s concerns and the complexity of
6
her case. One entry stated Ms Heath had been “unwell” with no clarification or
further information on what the problem was and/or how this may have impacted
on her condition.
Concern 1 and 2: Funding for home monitoring for anticoagulation
Funding responsibility for at-home INR monitoring, can sit across different parts of the
system depending on the clinical pathway and who held responsibility for ongoing
anticoagulation management. From an anticoagulation perspective, commissioning of
services is the responsibility of Integrated Care Boards (ICBs).
INR machines are not prescribable on an NHS primary care prescription, and may or
may not be included within routine anticoagulation service specifications. Most
commonly, patients are asked to provide their own INR machine, and then the strips
and other consumables are provided by the NHS on prescription via the
anticoagulation service directly or via their GP. However, this will vary by ICB.
This case is exceptional, however, as there was a clear clinical need for an INR home
testing machine. As such an approach for funding should have been made by the
anticoagulation service to the ICB for this individual, if not routinely included in the
service specification.
While at-home INR monitoring is not routinely commissioned, an Individual Funding
Request (IFR) process exists to enable consideration of funding in cases of clinical
exceptionality. In circumstances such as Ms Heath’s, an IFR application could have
been submitted by the responsible specialist clinician to support access to non-
routinely commissioned interventions where there is evidence of exceptional clinical
need. However, no application was made in this case.
We are aware you have also directed your Report to Essex ICB who will be providing
a detailed response. They have, however, informed the NHS England East of England
regional team that whilst they do not routinely commission at-home INR testing they
are always happy to receive IFR requests for exceptional cases.
Essex ICB have contacted providers to reinforce the role of the IFR process in
supporting access to non-routinely commissioned interventions where standard
policies do not meet the needs of clinically complex patients. They have reiterated that
requests must be made prospectively by the responsible clinician, and they must
ensure that patients are appropriately supported to understand available options
where treatments fall outside routine commissioning.
The ICB will continue to work with provider organisations to promote consistent
understanding and application of the IFR process, supporting equitable access to care
and reducing the risk of similar circumstances arising in future.

Concern 3: Lack of escalation
We note that you have also addressed your Report to Mid & South Essex NHS
Foundation Trust, who would be best placed to answer this concern as it relates to the
practice of specific practitioners.
Concern 4: Medical Records Non-Compliance
We note that you have also addressed your Report to Mid & South Essex NHS
Foundation Trust, who would be best placed to answer this concern as it relates to
practice of specific practitioners.
It is not clear from the Report which staff were non-compliant with keeping accurate
medical records, but both the General Medical Council’s Good Medical Practice and
Nursing and Midwifery Council’s Standards detail what is required of doctors and
nurses when keeping contemporaneous records.
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 Ms
Heath’s, 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.
Yours sincerely,
National Medical Director
NHS England
