CORONER’S LEGAL POWERS

Act 2009 and Regulations 28 and 29 of the Coroners (Investigations) Regulations
2013.

INVESTIGATION and INQUEST

On 19 September 2017, | commenced an investigation into the death of Georgia
Polydorou who was born on 12 July 1937. The investigation concluded at the

end of the inquest, which was conducted by me on 29 January and 6 March
2018.

The conclusion of the inquest was a narrative conclusion. | recorded a medical
cause of death of:

1a ventilator associated bronchopneumonia

1b subdural haematoma (operated 11.7.2017)

1¢ fall

2 mitral valve regurgitation, atrial fibrillation, hypertension, congestive cardiac
failure and Beta trait thalassaemia.

CIRCUMSTANCES OF THE DEATH

Mrs Polydorou was an in-patient at Homerton University Hospital due to an
exacerbation of congestive cardiac failure. She was recognised to be at
increased risk of falls. She was prescribed aspirin, clopidogrel and enoxaparin
during her admission. In the early hours of 10 July 2017, Mrs Polydorou fell
whilst going to the toilet. She was reviewed by the on call doctor and subject to
neurological review every 15 minutes for the first hour and hourly observations
thereafter. Her Glasgow Coma Score following the fall was 15/15. It was decided
that a CT scan would be undertaken if Mrs Polydorou showed signs of
deterioration such as headache, bleeding, dizziness or vomiting. Later in the
day, she was reviewed by a junior doctor. As she had had 10 sets of normal
neurological observations, a decision was made to revert to standard nursing
observations. Mrs Polydorou told family members that she had a headache but
she did not mention this to hospital staff. At 6.40 am on 11 July, a nurse went to
take Mrs Polydorou’s observations and found her unresponsive but breathing.
An urgent CT scan showed a large right sided acute subdural haematoma. Mrs
Polydorou was transferred to the Royal London Hospital where she underwent
an immediate right mini craniotomy and evacuation of the acute subdural
haematoma. Her recovery was extremely slow. Mrs Polydorou remained on a
ventilator in the Intensive Care Unit for several weeks. During which time, she
had multiple episodes of ventilator-associated pneumonia, which were treated
with antibiotics. Mrs Polydorou died at the Royal London Hospital on 18
September 2017. The Homerton University Hospital has revised its procedures
regarding anti-coagulation and falls as a result of Mrs Polydorou’s death.

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 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) Mrs Polydorou did not receive a CT scan within 8 hours of her fall
because she had a Glasgow Coma Scale of 15/15, she did not have any
abnormal neurological observations and was not taking Warfarin. Mrs
Polydorou was concurrently taking aspirin, clopidogrel and enoxaparin

during her hospital admission. All of which have the effect of thinning
the blood.

(2) Evidence from a consultant neurosurgeon established that there can be
a significant delay in elderly patients showing signs of head injury
following a fall, particularly where they are taking blood thinning
medications.

(3) Mrs Polydorou’s first language was Greek. Witnesses described her
ability to converse in English as “basic”. Whilst in A&E, her son acted as
an interpreter in order to obtain a reliable history. Following the fall, it
was decided that Mrs Polydorou would have a CT scan if she showed
signs of deterioration such as headache, bleeding, dizziness or vomiting.
Mrs Polydorou’s son, ig was told that his mother had fallen but was
not told of the symptoms that may indicate that her condition was
deteriorating. During a visit on 10 July, Mrs Polydorou told her son that
she had a headache but he did not realise the potential significance of
this. Mrs Polydorou did not report her headache to medical staff.

have the power to take such action.

Dear Ms Bourke,

| write in response to your Regulation 28: Report to Prevent Future Deaths, sent on
15 March 2018, regarding the death of Mrs Georgia Polydorou. ! was very sorry to
learn of Mrs Polydorou’s death.

We have considered the circumstances of Mrs Polydorou’s death and the concerns
you have raised, in relation to the work of NICE.

Our guideline on venous thromboembolism in over 16s: reducing the risk of hospital-
acquired deep vein thrombosis or pulmonary embolism (NG89) was published earlier
this month (updating and replacing an earlier guideline). It covers assessing and
reducing the risk of venous thromboembolism (VTE) and deep vein thrombosis
(DVT) in people aged 16 and over in hospital.

It includes the following new recommendation regarding the use of blood thinning
agents for people acutely ill in hospital:

1.4.6 Offer pharmacological VTE prophylaxis for a minimum of 7 days to
acutely ill medical patients whose risk of VTE outweighs their risk of bleeding:
+ Use LMWHI5] as first-line treatment.

+ If LMWHE] is contraindicated, use fondaparinux sodiuml6]. [2018]

[5] At the time of publication (March 2018), LMWH did not have a UK marketing authorisation
for use in young people under 18 for this indication. The prescriber should follow relevant
professional guidance, taking full responsibility for the decision. Informed consent should be
obtained and documented. See the General Medical Council's Prescribing guidance:
prescribing unlicensed medicines for further information.

[6] At the time of publication (March 2018), fondaparinux sodium did not have a UK

marketing authorisation for use in young people under 18 for this indication. The prescriber
should follow relevant professional guidance, taking full responsibility for the decision.

Informed consent should be obtained and documented. See the General Medical Council's
Prescribing guidance: prescribing unlicensed medicines for further information.

We note that Mrs Polydorou was prescribed aspirin, clopidogrel and enoxaparin. It’s
not clear whether she was on all of these at the one time - the use of all of these
blood thinning agents at once may have played a factor in the development of the
sudden subdural haematoma.

We also have a guideline on the assessment and early management of head injury
(CG176). This guideline includes recommendations on performing CT head scans in
patients on warfarin (who have no other indications for CT head scan), reflecting the
available evidence. The guideline developers considered there to be limited
evidence regarding patients using other antiplatelet or anticoagulant drugs within
studies deriving or validating clinical decision rules for determining which patients
need CT head scans - particularly, evidence in determining whether they are at
increased risk of intracranial haemorrhage. The guideline developers therefore made
a research recommendation on this issue.

Following our considerations, we believe both guidelines appropriately reflect the
available evidence and do not need to be amended at this time. Nevertheless, the
issues have been logged with the NICE guideline surveillance team, and will be
taken into account when the guidelines are next considered for review.

Yours sincerely,

Sir Andrew Dillon
Chief Executive
