3 | INVESTIGATION and INQUEST

On 23 March 2017, | commenced an investigation into the death of Mr Robert Dymond,
aged 61. The investigation concluded at the end of the inquest on 20 July 2017. The
medical cause of death was found to be:

1a Pulmonary Thromboembolism due to

1b Deep Vein Thrombosis

1c Obesity and Recent Surgery for Knee Replacement

The Conclusion of the inquest was a Narrative Conclusion:

Died from a recognised complication of surgery.

4 | CIRCUMSTANCES OF THE DEATH

On 20 May 2015, Mr Dymond has been placed on the waiting list for elective left knee
replacement surgery. As he was considered to be a high risk patient owing to his
previous medical history, which included a high BMI of 42.1, he had to undergo this at
UHCW which has a Critical Care Unit. He had an initial pre-op assessment on 21 July
2016 and a further pre-op assessment on 12 January 2017. Despite the fact that he had
undergone investigation and preliminary treatment for a suspected DVT in November
2016 at UHCW, | was informed that the pre-op assessment in January 2017 had noted
no changes since the previous one. The Consultant Orthopaedic Surgeon performing
the surgery was not informed of the events in November 2016. The surgery was
performed on 9 March 2017. On the morning of 10 March 2017, and despite appropriate
post-operative VTE prophylaxis, he suffered a massive thromboembolic event and
passed away on 11 March 2017.

5 | 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) Following referral to the UHCW DVT Clinic by his GP on 22 November 2016 with a
suspected DVT, Mr Dymond, having a Wells score of 2, was assessed as being ‘likely’
to be suffering from a DVT — the investigations included a D-Dimer blood result of 0.97 —
and he was discharged home with instructions to self-administer therapeutic LMWH
(Clezane) doses at home twice daily in his stomach pending an ultrasound scan booked
for 25 November 2016. The scan performed on 25 November 2016 apparently revealed
no evidence of a DVT and he was discharged back to the care of his GP. Although the
clinical management appeared to conform with the UHCW protocol in place at the time,
this protocol did not appear to conform with NICE Guideline 144 (specifically section
1.1.3) which (since 2012) advises a repeat proximal leg vein ultrasound scan 6-8 days
later for all patients with a positive D-dimer test and a negative proximal leg ultrasound
scan);

(2) Neither the Consultant Orthopaedic Surgeon nor the Anaesthetist performing the
operation on 9 March 2017 had been made aware of the DVT investigations/treatment in
November 2016;

(3) The DVT investigations/treatment in November 2016 did not appear to feature in the
second pre-operative assessment carried out on 12 January 2017.

ACTION SHOULD BE TAKEN

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

YOUR RESPONSE

You are under a duty to respond to this report within 56 days of the date of this report,
namely by 19 September 2017. |, the coroner, may extend the period.

the timetable for action. Otherwise you must explain why no action is proposed.

COPIES and PUBLICATION

| have sent a copy of my report to the Chief Coroner and to Mr Dymona's family.

| am also under a duty to send the Chief Coroner a copy of your response.

The Chief Coroner may publish either or both in a complete or redacted or summary
form. He may send a copy of this report to any person who he believes may find it useful

or of interest. You may make representations to me, the coroner, at the time of your
response, about the release or the publication of your response by the Chief Coroner.

Dear Mrs Whitting

Re: Robert _

| write in response to your Regulation 28 Report to Prevent Future Deaths issued on 25" July 2017.

The Trust’s Haematology Department devise and manage the Trust’s pathway for the management of
the DVTs and would have been pleased to have been given the opportunity of providing you with
evidence on this matter at the Inquest. In order to address your concerns their advice has been
obtained.

As you have stated the NICE guidance refers to the commission of proximal scans, which are taken at
the knee level and show the veins at that point. When a proximal scan is undertaken they advise
that a repeat scan should be undertaken 6-8 days later when there is a positive D Dimer and a
negative proximal scan.

The reason that this practice is not adopted by the Trust is because at UHCW, we undertake a more
extended scan as a routine which shows the leg veins below the knee to the trifurcation in the calf.
This is discussed in NICE guideline 144 section 4.1 which states that whole leg scans do not routinely
need a repeat scan. Therefore we believe that the Trust’s pathway goes beyond the minimum
requirements and accordingly we experience very low numbers of venous thromboembolism following
discharge from the DVT service.

Further, the Trust's standard practice in patients with a high risk Wells score and raised D-Dimers is to
contact the patient 5-7 days later and arrange a repeat scan if the symptoms are not settling. Only a
small proportion of patients who present with isolated distal DVTs extend to the proximal veins. Those
that do not extend, rarely lead to clinically significant emboli as recognised by the British Society of
Haematology national guidelines, a copy of which is attached by way of information.

Chief Executive Officer: Andrew Hardy Chairman: Andrew Meehan

The NICE rationale for repeating a scan is to detect those distal clots which have extended into the
proximal veins as in this situation the leg symptoms will not resolve and would be anticipated to
worsen. Therefore, for that reason patients whose symptoms are resolving are not recommended to
have a repeat scan.

It is also of note that the Trust use a very high sensitivity D - Dimer kit and the British Society of
Haematologists guidance states that patients with a moderate risk Wells score (1-2) can follow the
path of low probability if such a test is used.

The haematologists do consider it unlikely that the patient did have a proximal DVT as he was
untreated and does not appear to have had any further problems up until his surgery 4 months later.
As no DVT was identified by the investigations it would not have been relevant to the pre-operative
assessment and would not have been relevant to the operating team.

We hope this gives assurance that appropriate actions are in place for the management of DVT’s.
