CORONER

I am Samantha GOWARD, Area Coroner for the coroner area of Norfolk

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 12 May 2023 I commenced an investigation into the death of Derryck Lynn CROCKER
aged 77. The investigation concluded at the end of the inquest on 30 July 2024.

The medical cause of death was:

1a)
1b)
1c)
2)

Iatrogenic Cerebral Gas Embolism
Lung biopsy under computed tomography (CT) guidance

Lung lesion, suspected cancer

The conclusion of the inquest was:
Died due to the delayed recognition and treatment of a rare, but recognised complication of
a lung biopsy.

4

CIRCUMSTANCES OF THE DEATH

On 3 May 2023 Derryck Crocker attended hospital for a lung biopsy after previous
investigations had shown a suspicious mass. As part of the consent process the risks
identified were bleeding/haemoptysis, infection, pneumonia, pneumothorax, insertion of
chest drain & inadequate sampling. Air embolism was not a risk consented for at that time.

The procedure started at 13.00 hours & biopsies were taken at 13.18 hours. Immediately
after the samples were taken, Mr Crocker developed a cough. He then became semi-
unresponsive. The resuscitation team were called and his blood pressure and oxygen
saturations were said to be normal. A CT scan was done at 13.29 hours and was said not
to
demonstrate any significant abnormality, especially no evidence of an air embolism in the
chest.

Regulation 28 – After Inquest
Document Template Updated 30/07/2021

 A CT head scan was also done which demonstrated some low-density areas in the brain and
the possibility of a fat embolism was suggested, or an air embolism in the cerebro-vascular
fluid. The CT scan was reported at 1606 hours with these possible diagnoses mentioned.
This led to a discussion with the neurosurgical unit at Addenbrookes who advised that this
was not a surgical issue, but that a Neuro-Radiologist should be consulted if local
Radiologists needed further advice. Care was then handed over to the resusitation team.

Mr Crocker’s family gave details of him being significantly unwell after he was taken to the
Emergency Department. On the balance of probabilities this was due to a cerebral air
embolism caused by the biopsy, a rare but recognised complication of any invasive
procedure.

At 2004 hours a CT chest scan was ordered due to haemoptysis. Mr Crocker collapsed in
the CT department and had a brief seizure and then respiratory/cardiac arrest. After 2
cycles of CPR, return of spontaneous circulation was achieved and he was transferred to
ICU.

After his condition had been appropriately stablised, the Trust’s Lead Consultant in the
Hyperbaric Unit was contacted to discuss the possible benefit of delayed hypobaric
treatment for the cerebral air embolism (evidence was that treatment is most effective if it
is commenced within 4-6 hours of the embolism occurring). It was agreed to commence
such treatment and this took place on 3, 4 and 5 May 2023 but did not lead to an
improvement in his condition. On 7 May 2023 a diagnosis of a vegetive state was made
and he was provided comfort care and end of life support and died at James Paget
University Hospital on 10 May 2023.

CORONER’S CONCERNS

During the course of the investigation my inquiries 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:
(brief summary of matters of concern)

1.

2.

3.

4.

I heard evidence that there is a lack of understanding of the signs and symptoms of
an air embolism and the risk of this following any invasive procedure. I heard
evidence that nationwide and across all levels of specialism and seniority, there was
a lack of knowledge and that air embolism is not something that is routinely taught
as part of the training of doctors. While it is accepted that this is rare, it is life
threatening if not appropriately treated swiftly.

I also heard evidence that in areas where enhanced training has been provided, due
to adverse incidents such as Mr Crocker’s death, there appears to be increased
numbers of cases. This leads to the question of whether the lack of knowledge
means that such cases are missed and unreported and the rise is due to greater
awareness.

I heard that, in some cases, with timely treatment, outcome may be significantly
improved, but that with delayed recognition and therefore delayed treatment, death
is more likely.

I heard evidence that there is ongoing work with the Royal College of Radiologists
to provide them training on this issue, but that training was needed to ensure that
all other specialties who may encounter this condition have raised awareness
nationally.

ACTION SHOULD BE TAKEN

Regulation 28 – After Inquest
Document Template Updated 30/07/2021

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

Dear Ms  Goward, 

Regulation  28:  Report to  prevent futures  deaths 
Mr  Derryck  Crocker 

We  have  been  asked  to  respond  to  the  Regulation  28  form  which  has  been  passed  to  us  by the 
Royal College of Physicians,  London. 

We  are  deeply sorry to  hear of the  sad  death  of Mr Crocker and  we  send  our condolences  to  Mr 
Cracker's family. 

As the  report notes,  the  occurrence of an air embolism  is  a  rare  but recognised complication  that 
can  occur following an  invasive  procedure. 
In  the  case of CT guided  lung  biopsy,  radiology colleagues will be aware of the  importance of 
timely and  appropriate treatment,  as will  respiratory colleagues. 

We  suggest that this would  be suitable for a  patient safety alert such  as those  issued  by NHS 
England  to ensure that there  is a  timely and appropriate  response to such  cases,  with the 
intention  of preventing future  deaths.  The  British Thoracic Society will  make a  proposal to the 
NHSE  Patient Safety Committee and  will provide  any advice  and  support requested  of us. 

We  have copied this  letter to the  Royal College of Physicians,  London, the  Royal  College of 
Radiologists and  the  British  Society of lnterventional  Radiology. 

Yours sincerely, 

Chair of the  Board  of Trustees

Dear Ms Goward

INQUEST — MR DERRYCK CROCKER — 22/06/1945

Further to your letter, dated 1% August 2024 in which you requested further
assurance and update against the actions identified in the Inquest for Mr Crocker and
you asked for the information to be returned ta you bv the end of September 2024. i
apologise for the delay in responding to your request.

Foliowing the sad passing of Mr Derryck Crocker on 10" May 2023, an inquest was
heard and closed by yourself on 30" July 2024.

During the inquest P| Consultant in Acute Medicine, gave oral evidence in
relation to the Root Cause Analysis Investigation Report and associated Action Plan.
As per your letier it was noted that further assurance was requested in relation to two
of the actions, as follows:

Action 2b — HM Coroner requested an update following the observational peer
review, being completed by an interventional radiologist from Papworth Hospital,
which is scheduled to take place on 7" August 2024.

Action 6a — HM Coroner requested a copy of the approved SOP in relation to
deterioration of patients following lung biopsy.

In addition during the inquest our team noted that further assurance was requested in
relation to one further action as follows:

Action 27 — HM Coroner requested an update in October 2024 in relation to the
training module on air embolism being produced by EMM for the Royal College
of Radiologists.

| am now in a position to be able to provide the requested updates as follows:
Action 2b — The observational peer review was completed in August 2024 by [jj

Consultant Cardiothoracic Radiologist at Cambridge University
Hospitals. The Trust received the written outcome report {as per attachment 1).
Response from James Paget University Hospitals Page 2 (PDF)
On receipt of the peer review report in September the Radiology leads have
generated an action plan (as per attachment 2} for the department to address the
areas of improvement highlighted in the report. They have been meeting regularly
with the specialist Interventional Radiology leads to report and update progress on
these aciions.

Monitoring of the incident action plan and peer review action plan is through reporting
to the Radiology Department Governance meetings and by exception to their
Divisional Governance meetings. Escalation for actions not being met, as required,
is to the executive Jed Hospital Management Group with assurance reporting to the
Trust Patient Safety and Quality Committee.

Action 6a — A standard operating procedure for the management of a deteriorating
patient after image guided lung biopsy has now been implemented (as per
attachment 3).

Action 2f — QM Consultant Anaesthetist at the Trust, has received
confirmation that the air embolism training module has now been made availabie to
access by all Royal College of Radiologist members both in the UK and abroad and
that a REAL (Radiology Education and Learning) talk has also been scheduled.

| hope the attached provides the assurance requested, however, if you do need any
further information please do not hesitate to contact me.

Yours sincerely

Chief Executive

Dear Ms Goward, 

Re: Regulation 28: Report to Prevent Future Deaths in the matter of Derryck Lynn Crocker 

Thank you for sending us a copy of your report regarding the sad death of Mr Crocker. We have 
jointly reviewed the information available to us in the report via our Safe Anaesthesia Liaison 
Group (SALG). SALG is a collaborative project between the Association of Anaesthetists, NHS 
England’s Patient Safety team and the Royal College of Anaesthetists (RCoA). One of its core 
objectives is to analyse anaesthesia-related serious incidents and to share the learning with the 
specialty across the UK. 

In your report, you highlighted your concern that doctors across all specialties undertaking 
invasive procedures were not trained on the risk of air embolism following any invasive procedure. 
In further correspondence, you confirmed that you were sending this report to us as 
representatives of a specialty that undertakes invasive procedures, rather than due to any 
concerns about the care that Mr Crocker received from anaesthetists or intensivists. 

Anaesthetists directly undertake a range of invasive procedures that potentially could be 
complicated by air embolism, such as the insertion of central venous catheters. We can confirm 
that the risks of air embolism, and how to spot the signs and symptoms of an air embolism, are 
included in anaesthetists’ training to conduct these procedures1. Anaesthetists are often involved 
in the care of patients who are having invasive procedures delivered by other specialities. Air 
embolism, as a cause of a clinical emergency, is included in the Association of Anaesthetists’ 
Quick Reference Handbook (QRH)2. The QRH is a collection of guidelines on unexpected or 
uncommon anaesthesia-related emergencies. It aims to ensure the response to a crisis is as 
organised and all-encompassing as possible, at a time when the cognitive load can impair 
performance. The QRH helps clinicians focus on delivering care, using the skills and knowledge 
they already have. All anaesthetists are required to become familiar with guidelines for the 
management of anaesthetic emergencies, such as the QRH, so that they are automatically 
reached for in a crisis.3 Immediate access to emergency guidelines, such as the QRH, in all 
locations where anaesthesia is given is part of the standards for the RCoA’s Anaesthesia Clinical 
Services Accreditation (ACSA) scheme. 

We would be happy to respond to any questions that you might have. 

Yours Sincerely 

President

13th September 2024 

Dear Ms Goward, 

Further to your Prevention of Future Deaths Notice following the conclusion of your inquest 
(30th July 2024) into the death of Derryck Lynn Crocker who died on 10th May 2023, we like to 
extend our sympathy and condolences to the family and friends of Mr. Crocker. 

We note the known rare side-effect of an air embolism following lung biopsy occurred outside 
of  the  emergency  department.    Emergency  physicians  are  aware  of  the  possibility  of  air 
embolism following invasive procedures such as the insertion of central lines and therefore 
take precautions, such as ‘head down’ positioning, to prevent this.  However, we are grateful 
to you for highlighting this tragic case and we intend to raise awareness of the condition of air 
embolism amongst RCEM members by re-issuing a previously published case report involving 
air  embolism  as  well  as  considering  providing  specific  guidance  on  the  recognition  and 
management of air embolism on our RCEM eLearning educational platform. 

Yours sincerely, 

Chair, Quality in Emergency Care Committee

WARNING: External email, think before you click!

Dear Norfolk Coroner team,

The Royal College of Physicians (RCP) notes the content of the Regulation 28 report for the prevention of future deaths
related to the death of Derryck Lynn Crocker.

We send our sincere condolences to the family.

We recognise that air embolus is a serious but rare complication of invasive procedures.

For trainees in respiratory medicine their curriculum states related to lung biopsy:
“Trainees must be able to outline the indications for these procedures and recognise the importance of valid consent,
aseptic technique, safe use of analgesia and local anaesthetics, minimisation of patient discomfort, and requesting help
when appropriate. For all practical procedures, the trainee must be able to recognise complications and respond
appropriately if they arise, including calling for help from colleagues in other specialties when necessary”.

In addition, air embolus is a recognised complication of central line infection and all physician trainees at
Internal Medicine Stage 1, with similar guidance in their curriculum.

We would support the British Thoracic Society recommendation of an NHS Patient Safety Alert to raise wider
awareness.

Please confirm receipt of this email.

Kind regards,

19 September 2024 

Dear Mrs  Goward 

Regulation  28  Report to  Prevent Deaths:  Mr Derryck  Lynn  Crocker 

Matter of Concern: 

That there  is a  lack of understanding  of the signs and  symptoms of an  air embolism  and the 
risk of this following any  invasive  procedure,  and that air embolism  is  not something that  is 
routinely taught as  part of the training of doctors. 

Royal  College of Surgeons of England  response,  on  behalf of the Joint Committee on 
Surgical  Training  (JCST): 

Air embolism  is  something  that is well  recognised  by those involved  in Vascular 
lnterventional  Radiology and  lung  biopsies  i.e.  those closely  related to the  procedures where 
it  is  likely to  be complication  of (e.g.  those involved  in  obstetrics will  be  more  aware  and  up 
to  date with  amniotic fluid  embolism)  but other specialties are  likely to  be much  less familiar. 

In  terms  of specific surgical  specialties,  we would  draw your attention to the following 
examples: 

Cardiothoracic surgery:  There  is a  recognised  association with  air embolism  during 
cardiothoracic surgery  particularly  involving  cases where the cardiac chambers  are opened 
and  or cardiopulmonary bypass  or mechanical  circulatory support is used  to  support the 
patient's  circulation.  A knowledge  of techniques to  de-air the circulation,  as well  as the 
pathophysiology  or complications  of air embolism  is covered  in  several  areas within  the 
curriculum. 

Neurosurgery:  The risks  of air embolism  are  regularly discussed with trainees whenever 
operating  near the venous  sinuses.  The  principal  concern  being  large quantities  of air 
entering the veins within the  head  and going to the  heart causing  haemodynamic  instability 

In  respect of the  core  surgical  curriculum  completed  by  all  surgical  trainees: 

irm@rcseng acuk 

 We  have  reviewed  the  MRCS  examination  (2013  updated  2018)  &  Core  Surgical  Curriculum 
(CST)  (2017  and  2021)  syllabus,  and  discussed  this  issue  with  colleagues  who  are 
instructors  of the  Advanced  Trauma  Life  Support  (A TLS)  and  Care  of the  Critically  Ill 
Surgical  Patient  (CCrlSP)  courses. 

Assessment  and  management  of thromboembolism  is  part  of the  scope  of the  MRCS/CST 
curriculum  and  the  part  of the  syllabus  which  involves  placement/management  of central  line 
will  have  in  general  included  considerations  for complications  such  as  air  embolism.  An 
understanding  of the  risks  of anaesthesia  and  medical  gases  is  generic  to  surgical  training. 

We  believe  it to  be  a  commonly  asked  question  in  the  examination. 

There  is  a  brief mention  of it within  ATLS.  However,  delivery  of courses  can  vary  and  such  a 
specialised  complication/subject  will  not  have  been  covered  consistently.  There  isn't  a 
CCrlSP  scenario  related  to  air embolism  for the  same  reason. 

We  will  flag  this  within  our governance  mechanisms  for ATLS  and  CCrlSP  (A TLS  steering 
group  and  CCrlSP  clinical  lead  and  working  party)  and  will  draw  attention  to  the  risk  of air 
embolism  with  our membership  through  our regular communications. 

Thank  you  for drawing  this  to  our  attention. 

Yours  sincerely 

Chief Executive

Dear Dr Goward 

Regulation 28:  Report to prevent future deaths 

Thank you for your letter of 1 August 2024 concerning the death of Derryck Crocker following an air 
embolism.   

The  Royal  Society  of  Medicine  is  a  membership  organisation,  including  55  specialist  sections  that 
provide an extensive  programme of educational events  to ensure doctors keep up to date in their 
respective fields.  This puts us in an excellent position to provide ongoing education about the risks of 
air embolism and its management.   

In response to Regulation 28, I can confirm the following actions: 

•  The Presidents of all the relevant specialist Sections at the RSM have been asked to add in the 
risks of air embolism and its management to any appropriate educational events for the coming 
year. 

•  The Patient Safety section, which is running its 14th annual event for those at medical school and 
junior doctors, will use its Patient Safety Summit on 14 November 2024 to elevate the profile of 
the risks of air embolism and the signs and symptoms that might be seen following any invasive 
procedure.  This will be covered by a specialist in anaesthetics.   

Yours sincerely,
