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 3 May 2022, an investigation was commenced into the death of NIMO 
OSMAN, then aged 30 years. The investigation concluded at the end of an 
inquest with a jury, heard by me between 1 July 2024 and 5 July 2024. 

The inquest concluded with a short-form conclusion of natural causes. The 
medical cause of death was: 

1a hypoxic ischaemic brain injury (unknown aetiology)  
II   pulmonary thrombo-embolism, pneumonia, schizophrenia

CIRCUMSTANCES OF DEATH 

At the time of her death on 23 April 2022, Nimo Osman was in state detention 
because she was subject to a Hospital Order (in accordance with sections 37 
and 41 of the Mental Health Act 1983). Ms Osman was admitted to Rosebank 
Ward (a psychiatric intensive care unit) at the Tower Hamlets Centre for 
Mental Health, which is on the Mile End Hospital site, on 5 April 2022. The 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Tower Hamlets Centre for Mental Health is operated by the East London NHS 
Foundation Trust. 

Ms Osman’s principle mental health diagnosis was one of schizophrenia. 
Between 5-13 April 2022, Ms Osman spent a significant period of time in 
seclusion. On 19 April 2022, she was observed in a communal area of the 
Ward in an unresponsive state. A 999 call was made to the London 
Ambulance Service; however, shortly afterwards, Ms Osman was noted to 
become responsive and more alert. She was assessed by two doctors on the 
Ward who considered the most likely explanation was that Ms Osman was 
over-sedated. A decision was made to cancel the ambulance. 

Ms Osman was kept under observation and was noted to improve in following 
24-hours and blood test results came back within normal limits. 

Ms Osman collapsed on the Ward on 21 April 2022. An ambulance was 
called and she was transferred to the Royal London Hospital, where she died 
on 23 April 2022 as a result of hypoxic ischaemic brain injury.

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 the discovery of Ms Osman’s collapse on Rosebank Ward 
on 21 April 2022, it took staff a significant number of minutes to 
recognise that instead of just lying on the floor, Ms Osman was 
actually unrousable. A few minutes later a nurse arrived on the scene, 
who decided to summon the duty senior nurse (DSN) by radio, rather 
than activating the alarm system, which would have summoned the 
rapid response team sooner. 

The DSN contacted the duty doctor to inform them that there was a 
medical emergency, prior to calling an ambulance. In total, Ms Osman 
had been on the floor and unresponsive for over half and hour before 
an ambulance was called. I also viewed the CCTV evidence covering 
this course of events. 

I heard evidence from a consultant neurosurgeon and a consultant 
neuroradiologist. Their evidence was such that, in Ms Osman’s case 

 
 
 
 
 
 
 
 
 
 this delay would not have made a difference because she had suffered 
a catastrophic brain injury and her condition was likely to have been 
unsalvageable from the moment she was found unresponsive on the 
floor. However, I consider that a delay of circa 30 minutes in calling an 
emergency ambulance raises a considerable risk, if repeated in the 
case of another patient requiring emergency treatment at hospital. 

I was initially reassured by the evidence of a very senior member of 
nursing staff (Nurse A) about the work that has been done to educate 
all staff that anyone can call 999 for an ambulance if they consider it 
necessary, without seeking the advice of colleagues or the specific 
approval of a doctor. I was told by Nurse A that they were confident 
that the education and training undertaken with staff had had a 
positive impact and that a delay of this kind was unlikely to be 
repeated in the future. 

However, a senior nurse (Nurse B) who was on duty at the time of Ms 
Osman’s collapse told me in their evidence (over two years after Ms 
Osman’s death) that nursing staff cannot and would not call an 
ambulance of their own volition. Nurse B told me that she would only 
ever call an ambulance if told to do so by a more senior clinician. 
Nurse B went on to tell me that it was often the case that by the time 
an ambulance had been called and arrived, a patient would die; the 
manner in which this evidence was given led me to form the view that 
the Nurse B seemed to think that this was ‘just one of those things that 
happens’. 

While I was told by Nurse A (who seemed genuinely concerned) that 
this matter would be escalated and addressed, I was concerned that 
over two years since Ms Osman’s death this view was still held by a 
senior and experienced member of the nursing team who led a team 
of more junior nurses. My concern was such that I am not reassured 
that sufficient steps have been taken to prevent the recurrence of such 
a risk in the future. 

(2) I heard evidence from Nurse A, in the absence of the jury, about East 
London NHS Foundation Trust’s ‘Patient Safety Serious Incident 
Review Report’ (the SI Report). I was taken through the detailed 
‘Action Plan’ that was devised as a result of the various ‘service 
delivery problems’ (SDP), ‘care delivery problems’ (CDP), and 
‘additional lessons learned’ (ALL) that were identified as a result of the 
SI Report. 

 
 
 
 
 
 Not all of the SDPs, CDPs or ALLs are of such seriousness that I 
consider that they create a risk of future deaths unless action is taken. 
However, some of them do, in my opinion, reach that threshold. 

While the evidence of Nurse A and the accompanying Action Plan did 
provide prima facie reassurance that action has been taken, the 
evidence of Nurse B (who, as previously stated is relatively senior and 
experienced) has significantly undermined what I heard from Nurse A. 
The undermining of that evidence and reassurance from Nurse A, 
leads me to conclude that there is, at the very least, a realistic 
possibility that the learning and apparent changes put in place have 
not necessarily been fully embedded with all relevant personnel within 
East London NHS Foundation Trust. As such those concerns and risks 
persist. 

For this reason, I consider that further reassurance is required in 
relation to the following matters of concern: 

(a) CDP2 – ‘Staff should consider whether patients’ behaviour might 
be due to being physically unwell and not assume that this is due 
to their mental health condition.’ This concern relates, in part to the 
delay in calling for an ambulance (as per (1) above), but in my view 
it also has potentially wider implications for other patients. 

(b) CDP3 – ‘As per Physical Healthcare Policy, v.14.1, Feb 2021, 7.6, 
all patients should have a VTE risk assessment form completed 
and a VTE assessment on admission to the in-patient unit.’ While 
in Ms Osman’s case the expert evidence from a consultant 
histopathologist was that pulmonary thromboembolism was not a 
causative factor in her death, I consider that this matter does raise 
potentially significant risks for other patients. 

(3) With regard to the East London NHS Foundation Trust’s policy in 

relation to Venous Thromboembolism, I noted during the course of the 
evidence that this appeared to possibly conflict with NICE guidelines in 
some respects. There also appeared to be aspects of the policy that 
were ambiguous and open to different interpretations. I was told the 
policy remains in force and unchanged. The concern here is that 
possible ambiguity may lead to a non-universal interpretation of the 
policy, thereby putting patients at risk.

Date 7 October 2024 

Dear Sir  

RE: REGULATION 28 REPORT  

1.  This is a formal response to your Regulation 28 report issued at inquest on 12 August 

2024 where you set out concerns relating to the care of Ms Nimo Osman under the East 

London NHS Foundation Trust’s (the ‘Trust’) care. 

2.  I understand that at the inquest into Ms Osman’s death, you heard evidence from the 

Trust’s Deputy Borough Lead Nurse (‘BLN’) for Tower Hamlets outlining the learning that 

has taken place since her sad death. I understand that you remain concerned about the 

risk of future deaths in relation to the following areas: 

2.1. A senior nurse (Nurse B) who was on duty at the time of Ms Osman’s collapse told 

you  in  their  evidence  (over  two  years  after  Ms  Osman’s  death)  that  nursing  staff 

cannot and would not call an ambulance of their own volition. Nurse B told you that 

she would only ever call an ambulance if told to do so by a more senior clinician. 

Nurse B went on to say that it was often the case that by the time an ambulance 

had been called and arrived, a patient would die; the manner in which this evidence 

was given led you to form the view that the Nurse B seemed to think that this was 

‘just one of those things that happens’.  

2.2. You heard evidence from Nurse A, in the absence of the jury, about East London 

NHS  Foundation  Trust’s  ‘Patient  Safety  Serious  Incident  Review  Report’  (the  SI 

Report).  Given  the  evidence  of  Nurse  B,  the  undermining  of  that  evidence  and 

reassurance from Nurse A, led you to conclude that there is, at the very least, a 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 realistic  possibility  that  the  learning  and  apparent  changes  put  in  place  have  not 

necessarily been fully embedded with all relevant personnel within East London NHS 

Foundation  Trust.  As  such  those  concerns  and  risks  persist.  You  considered  that 

further reassurance is required in relation to the following matters of concern:  

2.2.1.  CDP2 – ‘Staff should consider whether patients’ behaviour might be due to 

being physically unwell and not assume that this is due to their mental health 

condition.’ This concern relates, in part to the delay in calling for an ambulance 

(as per (1) above), but in my view it also has potentially wider implications for 

other patients.  

2.2.2.  CDP3 – ‘As per Physical Healthcare Policy, v.14.1, Feb 2021, 7.6, all patients 

should  have  a  VTE  risk  assessment  form  completed  and  a  VTE  assessment  on 

admission to the in-patient unit.’ While in Ms Osman’s case the expert evidence 

from a consultant histopathologist was that pulmonary thromboembolism was 

not  a  causative  factor  in  her  death,  I  consider  that  this  matter  does  raise 

potentially significant risks for other patients.  

2.3. With regard to the Trust’s policy in relation to Venous Thromboembolism, you noted 

during the course of the evidence that this appeared to possibly conflict with NICE 

guidelines.  There  also  appeared  to  be  aspects  of  the  policy  that  were  ambiguous 

and open to different interpretations. You were told the policy remains in force and 

unchanged. The concern here is that possible ambiguity may lead to a non-universal 

interpretation of the policy, thereby putting patients at risk.  

3.  I wish to assure you and the family of Ms Osman that the Trust has reviewed the issues 

highlighted within the Regulation 28 Report and has planned the actions outlined below. 

RESPONSE 

Contacting emergency services 

4.  I share your concerns that one of the Trust’s nurses was under the impression that an 

ambulance could only be called if under the instruction of a more senior nurse. This is 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 certainly not agreed practice at the Trust. Nursing staff do not require permission to call 

emergency services.  

5.  I  can  confirm,  that  at  the  time  of  Ms  Osman’s  death  and  at  the  inquest,  Nurse  B’s 

Intermediate  Life  Support  (ILS)  training  was  up  to  date.  This  training  is  clear  in 

highlighting the expectations of a staff member attending a medical emergency. These 

expectations include that the staff member will undertake an initial check of the service 

user,  summon  s  help  internally,  and  ensure  an  ambulance  is  called.  No  permission  is 

required from a senior staff member. Following the inquest, the BLN spoke to Nurse B 

and  Nurse  B  confirmed  that  she  recognised  the  need  for  escalation  immediately  in 

medical emergencies as opposed to waiting for senior input. The BLN and Nurse B agreed 

that  Nurse  B  will  complete  refresher  ILS  training.  In  the  meantime,  Nurse  B  has  also 

completed a reflective piece in relation to this matter. 

6.  This matter was also brought up with all the Lead Nurses at the Trust shortly after the 

inquest to ensure that the message that ‘permission from senior staff is NOT required to 

call emergency services’ was disseminated to all nursing staff. As a reminder, this was 

followed up at the Lead Nurses meeting on 28 August 2024. 

7.  On  11  September,  after  a  recorded  safety  discussion  with  nursing  staff  on  29  August 

2024, the BLN circulated a memo to all Tower Hamlets Wards reinforcing the message 

that  staff  consider  that  service  user’s  physical  health  as  well  as  mental  health  can 

contribute to their behaviour. It also confirmed that there are no requirements to seek 

permission to call emergency services via 999.  

CDP2  

8.  It  is  important  that  all  staff  are  aware  of  the  impact  that  physical  health  as  well  as 

mental  health  can  have  on  a  service  user’s  behaviour.  As  outlined  in  the  BLN’s  oral 

evidence, to ensure this information is embedded, all Tower Hamlets in-patient nursing 

staff  and  social  therapists  undertake  a  mandatory  two-day  physical  health  training 

course. It includes content on service users presenting as unwell and whether this may 

be related to their mental or physical health. This course started on 03 May 2023 and is 

delivered regularly. Further training courses will take place on: 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 •  25 – 26 September 2024 

•  14 - 15 October 2024 

•  11-12 November 2024 

•  16 –17 December 2024.  

9.  Additionally,  Tower  Hamlets  clinical  staff  already  engage  in  once  weekly  emergency 

scenarios  that  include  when  it  is  appropriate  to  call  999.  By30  November  2025 

simulations will take place which include considerations whether something is a physical 

health verse mental health concern.  

10.  I understand that the BLN’s oral evidence was that VTE assessments form part of the 

two-day physical health training outlined in paragraph 8 above. Additionally, both the 

BLN and Clinical Director for Tower Hamlets circulated an email in January 2023 about 

the importance of undertaking VTE assessments. This was resent on 1 October 2024 to 

ensure that staff remain aware of the importance of these assessments.  

11. Additionally, all service user admissions are reviewed every morning between Monday-

Friday. The Ward Manager or Matron in attendance confirms that a VTE risk assessment 

is completed.  During the weekend and bank holidays, the weekend huddle will consider 

any admissions and a doctor clerks the patients in. These assessments are audited bi-

weekly as part of the service’s physical health assessment audits.  

12. Since  August  2024,  the  nurses’  Observations  and  Measurements  form  incorporates  a 

screening  question  for  VTE  risk.  It  is  a  mandatory  box  to  complete  on  the  form  and 

cannot  be  saved  on  RiO  (the  Trust’s  electronic  record  system)  until  the  question  has 

been responded to.  

VTE Policy 

13.  It  has  come  to  my  attention  that  the  inquest  only  considered  the  VTE  assessment 

information as provided in the Trust’s Physical Healthcare Policy v.14.1, February 2021. 

The Trust has a more recent and separate Venous Thromboembolism (VTE) Reducing Risk 

policy v. 3, March 2023. The information in the VTE policy is unambiguous and in-line 

with NICE guidelines. It is accepted that the VTE assessment information contained in 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 the Physical Healthcare Policy is not clearly set out. Therefore, the VTE information has 

been removed from the aforementioned policy in a soon to be published update and it 

has been made clear that the VTE policy is the appropriate reference. The changes to 

the Physical Healthcare Policy are expected to be agreed through the Physical Health in 

Mental Health Committee in November 2024.    

14. I hope this response provides sufficient reassurance to you and to the family of Ms Osman 

about the additional learning that has taken place at the Trust because of her death.  

15. I would like to offer my sincere and heart-felt condolences to the family at this difficult time.   

Yours sincerely 

Chief Medical Officer
