SUMMARY OF CORONER’S CONCERN

1.  Ms Corrigan was prevented from accessing healthcare related to an ongoing hormonal
disorder for which she had been receiving treatment prior to her detention. The treating
consultant  had  contacted both  the  mental health team  and the  Responsible Clinician
and received no response to his correspondence.

2.  There were significant omissions in clinical detail and recording in medical records.

3.  There was a lack of qualified and appropriately trained staff on the ward and there was
a  lack  of  compliance  with  the  Trust’s  policies  in  conducting  the  risk  assessments  for
Section 17 Leave.

4.  Ms Corrigan’s Section 17 leave was rescinded by the Responsible Clinician due to the
risk of self-harm and deterioration in mental state.  Ms Corrigan was permitted to access
the community on multiple occasions without the statutory permission required under

2

 the Mental Health Act as well as her being absent without leave not being  appropriately
reported or investigated.

5.  Datix forms were not completed when it became known that Ms Corrigan had accessed
leave on multiple occasions which did not comply with the requirements of Section 17
Mental Health Act and leave had been rescinded by the Responsible Clinician due to
Ms Corrigan’s risks to herself.

6.  Ms Corrigan’s Family was encouraged to privately fund psychoanalytic psychotherapy
in the community without the knowledge or understanding that Ms Corrigan did not want
to  undergo  this  therapy.  Expert  evidence  is  that  it  was  not  appropriate  in  all  the
circumstances.

7.  There were known issues  around the appropriate staff skills mix for the ward and an

overreliance on preceptorship nurses.

8.  Changes implemented for section 17 leave and observations from paper to electronic
records led to confusion and loss of visibility of key data useful for staff implementing
the systems. Key senior staff were not consulted and there was no audit of efficacy of
the change in systems.

6.

ACTION SHOULD BE TAKEN
In my opinion unless action is taken to address the above concerns then there is a significant
risk of future deaths, and I believe each of you have the power to take such action.

7.

INVESTIGATION AND INQUEST

On 8 January 2024, I commenced an investigation into the death of Katharine Emma
CORRIGAN, aged 27 years. The investigation concluded at the end of the inquest on 12
March 2026.

The conclusion of the inquest was 1(a) Consistent with Hanging

Section 4 (Part 1)
We as the jury have concluded based on the evidence seen and heard in court, that
Katharine's death is suicide and narrative.

There is a history of maternal suicide in Katharine's family. Katharine had suicidal thoughts
and tried to take her own life on previous occasions.

We are satisfied on the balance of probability that Katharine took actions 

 with the intention to

end her own life.

Section 4 (Part 2)

It is clear from the evidence that systemic failings at the mental health facility responsible for
Katharine's care contributed to Katharine being able to leave unescorted on the 22nd July
2023.

Staff awareness of policy and procedures was evidenced to be found lacking which
led to inadequate care.

Previous incidents of unauthorised leave were not adequately recorded and were not seen as
an opportunity to review procedures and implement adequate oversight to ensure Katharine’s
safety.

3

 There was insufficient exploration of a pre-existing hormonal condition which was possibly a
contributing factor to her emotional dysregulation.

Staffing skills on the ward on the 22nd July 2023 was insufficient and lacking in oversight.

The lack of senior staff involved in Katharine's risk assessment on that day led to her being
allowed to access section 17 leave unescorted.

8.

9.

CIRCUMSTANCES OF THE DEATH

Katharine  Emma  Corrigan  was  a  patient  detained  under  the  mental  health  act  at  the  Linden
Centre. Katharine died by suicide consistent with hanging 

 on 1st January 2024. It is probable the actual date of death was 22nd July 2023.
This was the day Katharine failed to return from unescorted leave. Leave was granted following
systematic failures over a period of time.

CORONER’S CONCERNS
During the course of the inquest I heard evidence 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.  Ms Corrigan was undergoing recognised therapy consistent with the national

guidelines for a pre-existing hormonal imbalance prior to her detention under the
Mental Health Act and was prevented from continuing with it. Ms Corrigan’s
Consultant Gynaecologist telephoned the ward and wrote twice to the Responsible
Clinician setting out the history and his willingness to continue to treat Ms Corrigan
with permission from her treating mental health team and on the second occasion with
an alternative plan for treatment under a local NHS gynaecology team. There was no
response, and Ms Corrigan was prevented from accessing this therapy. Expert
evidence was that this therapy was not contraindicated. None of this was recorded
appropriately in the medical records and no rationale given for Ms Corrigan not having
the available treatment.

2.  Policies and protocols on section 17 Leave granted under the Mental Health Act

(Section 17 Leave) were not properly understood by all staff and the required risk
assessments were not conducted by appropriately qualified and trained staff.

3.  Section 17 Leave forms and the process of recording of the required components for

timings and conditions of such leave had been changed by the Trust in May 2023 from
a paper system to electronic recording. The new system:

a.  omitted previously detailed information on the timings and conditions of the leave

that included required scrutiny by a qualified mental health nurse.

b.  Staff then recorded some information on the Bed State document and evidence
was this was not the purpose of this document and led to lack of visibility of any
patient who had not returned at the specified time. This was not questioned or
queried by senior staff.

c.  Senior management staff gave evidence that they were unaware of the lack of

visibility of the conditions for Section 17 leave under the new electronic system of
recording and had not been consulted when the changes were being made.

This was still the system in place.

4

 4.  There was a lack of Datix reports for Ms Corrigan accessing Section 17 leave when
the leave  had been rescinded by the Responsible Clinician.  Datix is the incident
reporting system utilised within the Trust. There had been no auditing of the new
system and senior managers had not been aware that Ms Corrigan had repeatedly
accessed unauthorised section 17 leave on multiple occasions prior to her death when
they gave evidence at the inquest.

5.  Ms Corrigan was absent without leave on multiple occasions and this had been

facilitated by staff. There was a lack of scrutiny as to how and why Ms Corrigan was
able to access leave that had not been authorised under section 17 Mental Health Act
and/or had been rescinded by the Responsible Clinician due to risks of self-harm. On
one occasion the Family went and searched for Ms Corrigan and returned her to the
ward with reported risks that she was found near to train tracks and where her mother
was buried.

6.  Ms Corrigan’s risk assessment and care plans had not been appropriately updated in

her medical records such that:

a.  They had not been developed in collaboration with her and did not contain:

i.
ii.
iii.

Early waring signs and triggers
Which mitigations were appropriate
Rationale as to why section 17 leaves were granted and/or rescinded

b.  With accurate risk information of her presentation and deterioration on the ward
and with concerns raised by Family which were put in writing to the responsible
clinician

c.  They contained inaccurate information on fire safety that had never been a part of

her presentation . It was not understood where this had emanated from.

d.  That Ms Corrigan had tried to get rid of all her clothes and this was behaviour Ms

Corrigan had previously displayed before attempting to end her life.

e.  That her mental health deteriorated in the days prior to her death and staff were

concerned about the risks to herself due to her low mood. Nursing staff instigated
the risk protocol such that Ms Corrigan should not have been able to access
section 17 leave until reviewed by the multidisciplinary team and there was
confusion about the Level of observations that had been put in place for Ms
Corrigan on 21 July. Medical records and section 17 leave forms were not
amended to ensure that staff could understand that due to her low mood with
consequent risks, leave must not take place until a medical review.

7.  There were known and ongoing issues with staffing and shift planning. There was an

overreliance on preceptorship nurses who the Trust knew according to national and
local policy and guidance, could not undertake all the roles required on the mental
health ward unsupervised.

8.  Preceptorship nurses were left in charge on the mental health ward on the morning of
22 July 2023 and a qualified nurse attended several hours after the commencement of
the shift. This was known about and management staff did not check that the
arrangements to mitigate this had been facilitated. There was no clear understanding
of how and by whom the nurse in charge role was being undertaken. This contributed
to Ms Corrigan accessing the community when leave had been removed temporarily
by the ward manager the previous evening in accordance with protocol. The medical
records were not clearly updated to reflect this, and the Section 17 Leave form had not
been updated.

5

 9. Expert evidence was that Dialectic Behavioural Therapy can be useful for a patient 

like Ms Corrigan to attempt to find strategies for learned maladaptive behaviours with 
complex trauma. Ms Corrigan’s family were encouraged to privately  fund intensive 
psychoanalytical psychotherapy as a mitigation for Ms Corrigan’s significant risk of 
killing herself.  Expert evidence was that this was not a therapy modality which was 
understood to be appropriate for Ms Corrigan:

a. specifically, to mitigate a significant and immediate risk of her ending her life
b.
for a detained patient with her presenting mental state and risks and, 
c. when Ms Corrigan had indicated that she did not wish to participate in it. 
d. When Ms Corrigan had not completed DBT.
e. who was reporting nightmares and flashbacks of complex trauma.
f. When it was understood by the professionals that this therapy would last for 

years and would involve delving into the unconscious. 

10. The Family had raised repeated  concerns that Ms Corrigan was not receiving 

appropriate treatment on the ward and about the risks to herself, verbally and in 
writing. The Family correspondence contained communications evidencing their 
concerns emanating from Ms Corrigan herself in text messages to the responsible 
clinician and other staff. Ms Corrigan was encouraged to undergo intensive 
psychoanalytical psychotherapy even though she explained she did not feel ready and 
her family did not know  or understand about how rare this form of therapy is and 
relied on her treating clinical team. They were encouraged to fund this and convey her 
to the therapy in the community without an understanding that Ms Corrigan did not 
wish for it. 

11. A digital system ‘Oxehealth’ was used to observe Ms Corrigan using tweezers as a 

risk item. This is not the purpose of this system.

Private & Confidential 
Ms Sonia Hayes 
HM Area Coroner for Essex 
Coroner’s Office 
Seax House 
Victoria Road South 
Chemlsford  CM1 1QH 

Dear Ms Hayes, 

Katharine Corrigan (RIP) 

Trust Headquarters 
The Lodge 
Lodge Approach 
Wickford 
Essex 
SS11 7XX  

I write to set out the Trust’s formal response to the report made under paragraph 7, Schedule 5, 
of the Coroners and Justice Act 2009 and regulations 28 and 29 of the Coroners (Investigations) 
Regulations 2013, dated 1st June 2026. 

This report was received by the Trust following the inquest into the sad death of Ms Corrigan 
(RIP). 

I would like to begin by extending my deepest condolences to Ms Corrigan’s family. The Trust 
expresses its sincere sympathies and acknowledges the profound nature of their loss. 

The matters of concern as noted within the Regulation 28 Report have been carefully reviewed 
and noted.  I will now respond in full to the concerns raised in the hope that this provides both 
yourself and Ms Corrigan’s family with comprehensive assurances of the changes that have 
been made at the Trust to address the concerns you have raised.  

Concern 1) Ms Corrigan was prevented from accessing healthcare related to an ongoing 
hormonal disorder for which she had been receiving treatment prior to her detention. The 
treating consultant had contacted both the mental health team and the Responsible Clinician 
and received no response to his correspondence. 

Response: 

In line with the evidence provided at this Inquest, it is accepted that the request from the 
practitioner to see Ms Corrigan in relation to her concerns around a hormonal disorder ought to 
have been further explored.  Professional curiosity and ensuring patients are given a voice 
remain key objectives for the Trust, this is facilitated by access to medical and nursing staff and 
support teams. Furthermore, the Trust is continuing to explore partnerships with external 
agencies in order to enhance and fully support patients with their individual care needs. 

Concern 2) There were significant omissions in clinical detail and recording in medical records.  

1 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Response: 

The Trust acknowledges the Coroner’s concern regarding the quality and completeness of 
clinical documentation and specifically, the shortcomings in the way documentation and source 
materials were referenced and applied within the subsequent Patient Safety Incident 
Investigation report.  

As a result, the Trust has introduced enhanced assurance arrangements, including structured 
checklists to ensure relevant patient records and supporting documents are identified, reviewed 
and appropriately referenced. These arrangements were finalised in January 2026.  

Additionally, a new form for the leave risk assessment has been development which affords 
clarity on the completion of the risk assessment, the outcome of the review and the type of 
leave (un-supervised / escorted etc) that has been approved.  The form also now specifically 
includes the time a patient has left for the agreed leave and the time they are due to return as 
well as the actual time of return. This will allow for clearer monitoring and safety controls. The 
development of these controls is an ongoing exercise in order to ensure these remain robust. 

Further, the Trust initiated a Record Keeping Safety Improvement Programme (SIP).  This SIP 
program has focused on improving patient safety in respect of documentation specifically. The 
approach will be to support continuous learning and improvement and regular review. There SIP 
aims to continually review learning in relation to record keeping.   

Finally, the Trust has initiated a person centered audit (through the Trust Tendable audit 
system) which reviews care plans.  Audits are undertaken on a monthly basis.  These audits are 
supported by Practice Nurse Educators. Tendable audits have remained in place at the Trust 
with the last update to this process being completed in October 2024.  

Concern 3) There was a lack of qualified and appropriately trained staff on the ward and there 
was a lack of compliance with the Trust’s policies in conducting the risk assessments for 
Section 17 Leave. 

Response:   

As outlined above, documentation standards in general remain an area of focus for the Trust 
with a number of initiatives being undertaken Trust wide to improve these standards (including 
the SIP referenced above). 

As outlined in the statement submitted by 
(Chief Nurse), there is a clear Trust-
wide understanding of the need to ensure effective rostering which underpins safe, high-quality 
care by ensuring the right skill mix, proactive planning, and timely publication of rosters in line 
with Trust requirements. There is further work and oversight regarding rostering at ward level 
that has been enhanced to support improved approval of rosters within the timescales 
recommended.  

Again, as set out in the evidence from 
led oversight safer staffing meetings that has senior nurse leadership. The purpose is to ensure 
that staff are rostered in line with recognised budgeted establishments taking into consideration 
patient acuity and safety. The introduction of a shift-level sign-off is being included where the 
matron must verify that an experienced RN is available to lead the ward.  

 from 2025 the Trust introduced Executive 

Concern 4) Ms Corrigan’s Section 17 leave was rescinded by the Responsible Clinician due to 
the risk of self-harm and deterioration in mental state.  Ms Corrigan was permitted to access the 
community on multiple occasions without the statutory permission required under the Mental 

2 

 
 
 
 
 
 
 
 
 
 
 
 
 Health Act as well as her being absent without leave not being appropriately reported or 
investigated 

Response:  

The above finding was explored carefully in Court. It was acknowledged that these gaps were  
contributed to by the omissions outlined in concern 2 above.   

The Trust has set out clear expectations around daily leave risk assessment for mental health 
patients. These must be completed and documented by a registered clinician such as a nurse, 
occupational therapist, or social worker who evaluates the patient’s current mental state and 
risk profile immediately before leave is taken. While the Responsible Clinician (usually the 
Consultant Psychiatrist) holds overall responsibility for authorising leave, the dynamic 
day-to-day assessment is carried out by registered ward clinicians, supported by the Nurse in 
Charge, who ensures these assessments are completed consistently and allocates tasks 
accordingly.  

Again, there is a Trust expectation that all assessments, handovers, decisions and rationale 
related to leave must be accurately recorded in the patient’s electronic clinical record. 

To support these expectations a review has been undertaken to ensure a standardised 
approach across the Trust that clearly reiterates the roles and responsibilities involved in 
completing daily leave risk assessments. Details as regards when these reviews were 
undertaken are noted above.   

The Trust will measure the effectiveness of its standardised approach to daily leave risk 
assessments across the entire Trust through the auditing of documentation quality, adherence 
to policy, and whether assessments are completed by the correct professional group.  

Training uptake and competency sign-off, incident trends, and staff feedback on their clarity of 
roles will also provide important indicators that will be reviewed through the Care Unit 
Accountability Framework that has an Executive Chief Medical Officer as chair.  

Where the Responsible Clinician (RC) makes a decision to rescind or amend a patient's Section 
17 leave, this decision is communicated verbally to the nursing team at the earliest opportunity 
and is documented contemporaneously in the patient's clinical record. This decision may be 
made during a scheduled ward review or at any other time if clinically indicated. 

Following the decision, the patient's care plan is updated to reflect the revised leave 
arrangements. The care plan forms part of the routine clinical handover process and is reviewed 
at both the commencement and conclusion of each nursing shift. Current Section 17 leave 
status and any restrictions are specifically discussed during these handovers to ensure that all 
members of the multidisciplinary team are aware of the patient's authorised leave 
arrangements. 

The expectation is that leave is facilitated only in accordance with the Responsible Clinician's 
most recent documented decision and the current care plan. To strengthen the above 
expectations, Section 17 leave plans are discussed within handovers, MDT, ward reviews and 
also outcomes of the MDT/Reviews are circulated to the ward team via emails which will include 
regular updates and any changes to decisions and arrangements.  

Concern 5) Datix forms were not completed when it became known that Ms Corrigan had 
accessed leave on multiple occasions which did not comply with the requirements of Section 17 

3 

 
  
 
 
 
 
 
 
 
 
 
 
 Mental Health Act and leave had been rescinded by the Responsible Clinician due to Ms 
Corrigan’s risks to herself.  

Response:   

Following on from the Action Plan documentation prepared for the Court, the Trust accepts that 
there were gaps in the completion of DATIX forms in respect of Ms Corrigan’s care. 

EPUT accepts that it is vital to ensure that staff are clear when it is appropriate to raise a 
DATIX. All staff have been DATIX trained, which includes registered and non-registered staff. 
The Trust correlates incidents and site logs with DATIX records as part of a daily audit in order 
to measure compliance with expected DATIX entries.   

From 2024, the Trust introduced Datix dashboards for all care units that are overseen by the 
local leadership team. These dashboards provide immediate awareness of incidents identifying 
hot spots and trends. They allow for proactive rather than reactive management, helping  to 
ensure that the "so what" question of, for example, high/low incident rates, is answered with 
concrete safety actions. 

The Chief Nurse, chairs a weekly Emerging Incident Review (set up in 2025) with its primary 
role to move from reactive to proactive learning, ensuring that significant incidents are 
investigated promptly and that learning is shared across the Trust. This review group is 
attended by Service Leads and representatives of the patient safety team.  

Concern 6) Ms Corrigan’s Family was encouraged to privately fund psychoanalytic 
psychotherapy in the community without the knowledge or understanding that Ms Corrigan did 
not want to undergo this therapy. Expert evidence is that it was not appropriate in all the 
circumstances. 

Response:   

It is respectfully submitted that this concern relates more to a clinical judgement issue rather 
than a concern relating to future deaths.  However it is accepted that colleagues should be 
reminded of the need to keep under consideration issues relating to capacity and consent 
around access to care. The findings set out in this Regulation 28 Report will be shared with 
services involved in Ms Corrigan’s care.  

Concern 7) There were known issues around the appropriate staff skills mix for the ward and 
an overreliance on preceptorship nurses.  

Response:  Please see our reply at point 3 above. 

Concern 8) Changes implemented for section 17 leave and observations from paper to 
electronic records led to confusion and loss of visibility of key data useful for staff implementing 
the systems. Key senior staff were not consulted and there was no audit of efficacy of the 
change in systems.  

Response:   

The services now do not use paper records. Patient ward boards record the date and times of 
patients leaving for Section 17 leave with the exact expected return times. These Boards are 
reviewed each hour. Process changes now permit only the Nurse in Charge to sign S.17 
records.  

4 

 
 
 
 
 
 
 
 
 
 
 
 
   
 
 
 In terms of the processes around Section 17 leave, the key priority is to strike a balance 
between the therapeutic benefits of time spent away from hospital and the safety risks that 
might arise for the patient or the public. The S17 leave Policy applies to both voluntary patients 
and those detained under the Mental Health Act, with the latter requiring formal Section 17 
approval from their Responsible Clinician.   

Again, it remains strict practice that before any S17 leave is considered or agreed, staff will 
conduct ongoing risk assessments, review medication, and agree on a support plan.  

The policy that is in place also provides guidance on responding to any deterioration in a 
patient's health.  

The Trust will measure the effectiveness of its standardised approach to daily leave risk 
assessments across the entire Trust through the auditing of documentation quality, adherence 
to policy, and whether assessments are completed by the correct professional group.  

I hope that I have provided some reassurances around the steps that we have taken to address 
the issues of concern contained within your report.  We know there is an acute need to embed 
and effect change, hence we will monitor the above provisions to ensure these are contributing 
to our overall aim of keeping patents safe and delivering therapeutic care. 

Please do let me know if you require any further information at this stage, including copies of 
any of the documents referred to above.   

We understand that a copy of this reply will be shared with the family.   

Yours sincerely 

Interim Deputy CEO and Executive Chief People Officer
