CIRCUMSTANCES OF THE DEATH

Mary Pomeroy was a frail 89 year old female who suffered fatal traumatic injuries that were inflicted upon
her (following being pushed over and falling to the ground) by a fellow in-patient on their shared ward at
Derriford Hospital, Plymouth in March 2022.

Section  2  of  the  Record  of  Inquest  (which  recorded  the  medical  cause  of  Mary  Pomeroy’s  death)  was
determined as:

1a – combined physiological effects of bilateral humeral fractures in an elderly patient
1b – traumatic fall to ground following being pushed over

Section 3 of the Record of Inquest (which answered how, when and where Mary Pomeroy came by her
death) was determined as:

‘Mary Pomeroy was an in-patient at Derriford Hospital, Plymouth when, on 3 March 2022, she was pushed
over on to the floor by a fellow patient who had been suffering with psychotic symptoms and cognitive and
behavioural problems.  Mary suffered fractures as a result of this trauma.  Mary’s condition deteriorated
after, and as a direct result of, this incident, and she died on 15 March 2022 at Derriford Hospital, Plymouth.

 There was a lack of assessment and management of the patient who pushed Mary over and this materially
contributed to the incident occurring and therefore to Mary’s death.’

Section  4  of  the  Record  of  Inquest  (which  provided  the  conclusion  as  to  Mary  Pomeroy’s  death)  was
determined, in narrative form, as:

‘Mary Pomeroy died from injuries suffered following being pushed over by a fellow patient on the same
ward in hospital – this fellow patient had psychiatric, behavioural and cognitive difficulties and wasn’t being
closely supervised on the ward.’

CORONER’S CONCERNS

During the course of the investigation and inquest the evidence revealed matters giving rise to concern.
In my opinion there is a risk that future deaths will occur unless action is taken. In the circumstances it is
my statutory duty to report to you.

The MATTERS OF CONCERN are as follows:

Derriford Hospital in Plymouth is the main acute hospital site managed by UHP NHS.  UHP NHS carried out
a Root Cause Analysis (RCA) investigation in respect of the circumstances which led to Mary Pomeroy being
pushed  to  the  ground  by  a  fellow  patient  on  a  ward  at  Derriford  Hospital,  Plymouth  and  her  death
thereafter.  This investigation culminated in a written investigation report which was given executive sign
off on 14 July 2022, by the SI panel chair and chief nurse of UHP NHS.

The main body of the investigation report concluded that the incident which led to Mary Pomeroy being
pushed to the ground by a fellow patient was ‘a rare and devastating accident for which could not
have been foreseen’.

The  summary  of  the  SI  Panel  Meeting  Review,  chaired  by  the  Chief  Nurse  on  4  July  2022,  stated  that
‘overall  it  was  considered  that  [the  patient  who  pushed  Mary  Pomeroy]  was  managed
appropriately  during  his  admission  to  UHP  NHS  and  concluded  that  this  was  a  deeply
unfortunate accident, but not one that could have been anticipated and therefore prevented
by staff.’

The inquest heard evidence that the patient who pushed Mary Pomeroy to the ground on 3 March 2022
had done almost exactly the same thing to another patient on the ward only two days previously, on 1
March 2022 – this incident was discussed in the main body of the RCA investigation report, but not referred
to at all in the SI Panel Meeting Review summary.  The inquest also heard evidence that the patient who
pushed Mary Pomeroy had been involved in a number of incidents where he had used physical force on
staff members on the ward in February 2022.

At the inquest, the author of UHP NHS’s investigation report (who was the Matron of the relevant ward)
accepted, in evidence, that the patient who pushed Mary Pomeroy should, on 3 March 2022, have been
subject to enhanced observations of care – this was on the basis that previous assessments in November
2021 and January 2022 had shown that this was required for him owing to his psychiatric and behavioural
presentation (which had become more concerning by the end of February/beginning of March 2022) and
also because of very recent and specific concerns regarding his behaviour which should have been obvious
to ward staff following the incident on 1 March 2022.

The Matron accepted, in evidence, that had enhanced observation and care been in place for the patient
(which could have taken a number of forms following assessment, depending on what would have been
most  clinically  and  therapeutically  appropriate  at  the  time)  then  he  should  have  been  prevented  from
being in a position where he was able to push Mary Pomeroy to the ground on 3 March 2022.

The Matron accepted, in evidence, that UHP NHS’s RCA report had been incorrect to conclude that the
type of incident that occurred on 3 March 2022 could not have been foreseen.  The Deputy Chief Nurse of

 UHP NHS accepted, in evidence, that the SI Panel Meeting should have interrogated the relevant facts and
chronology more.

The inquest determined that the incident on the ward on 3 March 2022 was foreseeable, based on the
concerns about the patient’s behaviour, the likely triggers for him becoming distressed and aggressive and
the almost identical incident that had occurred on 1 March 2022.  The inquest also determined that the
lack of assessment and management of this patient’s behaviour and needs materially contributed to the
incident which led to Mary Pomeroy suffering injuries and led to her death.

It is unfortunately clear, when comparing the evidence heard at the inquest with the findings of UHP NHS’s
RCA  report,  that  there  was  inadequate  analysis  of  this  serious  incident  by  UHP  NHS,  with  concerning
circumstances  surrounding  the  care  provided  not  being 
identified  –  therefore  appropriate
recommendations  to  inform  future  care  provision  were  not  given  consideration  as  part  of  the  RCA
investigation/report.

If UHP NHS do not identify concerning matters when carrying out internal investigations and do not take
steps to try and learn from serious incidents when they occur, then there is an obvious, significant and
continuing risk of future deaths occurring arising out of healthcare provision provided.

Mr Nicholas Lane 
HM Area Coroner 
County of Devon and Plymouth and Torbay 

Dear Mr Lane 

Re: Mary Margaret Pomeroy deceased – Regulation 28 Prevention of Future Deaths Report 

I  write  in  response  to  your  Regulation  28  Report  dated  01  April  2025  concerning  the  sad  death  of  Mrs  Mary 
Margaret Pomeroy. 

I would like to express our sincere condolences to Mrs Pomeroy’s family.  

We have reviewed the concerns you have raised in the report regarding the investigation into the circumstances 
surrounding the death of Mary Margaret Pomeroy, which was undertaken using the Serious Incident Framework, 
as was mandated by NHS England at the time of the incident.  

In June 2024, in line with other NHS Organisations across England, University Hospitals Plymouth NHS Trust 
(UHP) transitioned to the use of the Patient Safety Incident Response Framework (PSIRF) and ceased the use 
of the Serious Incident Framework (SIF).  

The  principles  set  out  in  the  Patient  Safety  Incident  Response  Framework  have  fundamentally  shifted  the 
approach to safety, and investigations into safety incidents within UHP. The PSIRF is not solely an investigation 
framework  but  instead  looks  to  support  and  develop  a  culture  of  transparency  and  learning,  supporting  the 
development and  maintenance of an  effective  patient  safety incident response system. It incorporates x4 Key 
Elements: 

1.  Compassionate  engagement  and  involvement  of  those  affected  by  patient  safety  incidents  (patients, 

families and staff) 

2.  Application of a range of system-based approaches to learning from patient safety incidents 
3.  Considered and proportionate responses to patient safety incidents 
4.  Supportive oversight focused on strengthening response system functioning and improvement 

In support of the above elements, the Trust has taken the following actions: 

1.  Creation of a patient communication handbook 

a.  This is provided to patients and their families who are involved in safety incidents.  

2.  An information leaflet has been created for staff, outlining the purpose of the investigation, the process 

that will be followed and signposting to support option.  

3.  The ongoing development of a Just and Restorative culture has been added to the Terms of Reference 

for a Key Quality sub-committee (the Care Improvement Group) 

a.  Research  indicates  that  barriers  to  transparency  included  fear,  blame  and  shame.  A  just  and 
restorative  culture  is  key  to  addressing  this.  By  ensuring  the  ongoing  development  of  such  a 
culture is included in the Terms of Reference for the Care Improvement Group, two elements are 
achieved: 

Working in partnership with the Peninsula Medical School 

Chairman: 

     Chief Executive: 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 i.  The delegated authority of the Safety, Quality, People and Culture Committee (a board 
sub-group) to the Care Improvement Group ensures that the group has the authority to 
undertake any actions as it deems necessary to promote a Just and Restorative Culture 
ii.  Regular update on progress in implementing this culture will be provided to the Safety, 

Quality, people and Culture Committee, ensuring regular, board level oversight 

4.  Recruitment to x2 Learning Response Lead posts.  

a.  Both Learning Response Leads have completed mandatory training in compliance with national 
guidelines set out in the Patient Safety Incident Response Framework. Whilst not a requirement, 
both UHP Learning Response leads have backgrounds associated with the delivery of clinical 
care (as a paramedic and a biomedical scientist) with professional registration. 

b.  These  specialist  investigators  will  undertake  any  Learning  Response  commissioned  by  the 
Patient  Safety  Incident  Response  Group.  In  addition,  these  individuals  will  provide  specialist 
support and guidance in relation to  other ongoing safety review processes (e.g. local Care Group 
investigations).  

c.  The support of the Learning Response Leads will ensure that investigations within UHP move 
away from Root causes Analysis (which has been shown to be ineffective) and towards a model 
which  supports  understanding  outcomes  within  complex  socio-technical  systems  such  as 
healthcare..  

5.  Recruitment of two Patient Safety Partners. The remit of the Patient Safety Partner role is set out in the 
National Patient Safety Strategy through the Framework for Involving Patients in Patient Safety. Patient 
Safety Partners are lay people, who have extensive experience of receiving care and on occasion, may 
have been involved in safety incidents. As such, they provide a different perspective on patient safety, 
removing the potential of influence by organisational bias or historical systems.  

a.  The UHP Patient Safety Partners not only sit on key governance committees, but also support 
investigation processes through the ongoing review and challenge of the investigation process 
(during the investigation) and provide similar scrutiny to final reports.  

6.  Developed a new policy for the investigation of safety incidents, which includes new investigation methods 
7.  Redesigned our governance processes to further promote transparency and proactive multidisciplinary 
review of quality concerns and undertaking assurance work on any actions implemented as a result of 
those concerns. We have done this by ensuring: 

a.  Where  investigations  are  commissioned,  the  Terms  of  Reference  are  agreed  through  a  multi-
disciplinary approach and discussed with patients and families. As part of this process we would 
consider any previous similar incidents and ensure key leads (this  may be  medical  or nursing 
leads,  Allied  Health  Professionals,  patient  advocates,  managerial  support  or  any  other  key 
personnel involved in the delivery of patient care) are involved in the investigation processes. 

The investigation process University Hospitals Plymouth NHS Trust now follows is undertaken in accordance with 
the Patient Safety Incident Response Plan and includes the following: 

1.  Patient safety incidents are recorded  via a number of processes, including a healthcare safety incident, 
patient concerns raised through a complaint or PALs. Staff concerns can also be raised as per the NHS 
‘Freedom to Speak Up’ policy. On the identification of a concern, a DATIX is raised.  

2.  The  concern  is  then  raised  at  the  Patient  Safety  Incident  Response  Group  (‘PSIRG’),  via  a  formal 
escalation  report  (this  meeting  is  chaired  by  the  Trust  Patient  Safety  Specialist  and  attended  by  a 
multidisciplinary team that includes subject matter experts). 

a.  Concerns can be raised through any source, including incidents reported to Datix, patients, staff, 
key external stakeholders, scrutiny of quality outputs or in response to key national reports and 
findings.  

3.  The PSIRG commissions a review as follows: 

Working in partnership with the Peninsula Medical School 

Chairman: 

    Chief Executive: 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 a.  There a number of different review options which are included in a separate file. The PSIRG will 

collectively decide the most appropriate response type. 

b.  The terms of reference are agreed through a Multi-Disciplinary Discussion. These are discussed 

with patients and loved ones to ensure they encompass any concerns they have 

c.  The review is assigned to a lead reviewer, who has the appropriate training and subject matter 

expertise to undertake 

4.  The review is undertaken using a range of system-based approaches to learning keeping family and loved 

ones involved as much as they wish. 

5.  A  draft  of  the  review  is  discussed  at  an  “Open  Door”  event  which  is  attended  by  a  range  of  key 

stakeholders, ensuring that all perspectives of the incident are discussed.  
a.  The draft is also shared with family and loved ones for their input.  
b.  Recommendations for improvement are agreed with all key stakeholders 

6.  The review outcomes and process are presented to the Care Delivery Group, a meeting chaired by either 
the  Head  of  Quality,  Safety  &  Governance,  or  the  Chief  Nursing  Officer  and  Chief  Medical  Officer  as 
required..  

a.  The  Care  Delivery  Group  (CDG)  seeks  assurance  on  the  extent  of  the  review  process  and 
considers the appropriateness of the findings and agrees the recommendations made. In relation 
to review outcomes, the CDG may: 

i.  Be  assured  on  the  review  process  and  outcomes,  agreeing  with  and  endorsing  the 

recommendations 

ii.  Challenge any part of the review process or outcome.  
iii.  Commission  further  review  where  necessary  (in  cases  where  it  is  felt  the  review 
presented was not robust enough, or did not capture the correct recommendations) 

b.  The recommendations are assigned to a key stakeholder to then develop specific actions to drive 

improvement.  

c.  Assurances  on  the  progress  and  implementation  of  recommendations  is  sought  by  the  Care 

Improvement Group, which is chaired by the Head of Quality, Safety & Governance. 

I do hope that this detailed explanation provides you with the assurance that you require but please do not hesitate 
to contact me if you should require any further information. 

Yours sincerely
