Matthew Zak Sheldrick (Matty) · Prevention of Future Deaths report

On 23rd November 2022 I commenced an investigation into the death of Matthew Zak Sheldrick (Matty). Matty identified as non-binary and preferred the use of the pronouns they and them.

The investigation concluded with the Inquest being held over a two-week period which concluded on Friday 13th December 2024.

At the end of the Inquest, I concluded that:

On 3rd November 2022 at around 02.21 Matty had attended Accident & Emergency at the Royal Sussex County Hospital in crisis following a further deterioration in their mental health. This was the second admission in no less than 5 weeks. During this second admission they were experiencing intense suicidal thoughts.

Later on 4th November 2022 they were formally assessed under the Mental Health Act and the decision taken was not to detain them. Provision was however made for Matty to be able to stay in the hospital that night if they wished.

However, Matty left shortly afterwards and tied a ligature around their neck and suspended themself from ████████
████████. Their intentions at the time of carrying out this act remain unclear.

The following issues contributed to their death:-
1. The fact that Matty’s private housing accommodation, which had been arranged following their move to Brighton, was not suitable due to their ongoing sensory issues.
2. The fact that there had been no psychiatric bed available to Matty during their first admission to Accident and Emergency Department in September. They stayed in the Accident and Emergency department for 26 days during their admission between 5th and 30th September 2022. This meant that there was no meaningful therapeutic input at that time.
3. The fact that Accident and Emergency Department was not a suitable environment for a neurodivergent individual and the 26-day period of their stay contributed to the deterioration of their mental health difficulties.
4. The fact that there was a general lack of inpatient bed provision for informal patients and in particular for those who are autistic and non-binary who require to be on a mixed ward.
5. The fact that Matty was discharged from the Crisis Resolution Home Treatment Team on 18th October 2022 before being picked up by Assessment and Treatment Service. This left a gap in service provision for Matty.
6. The rigidity of the referral process to Transforming Care in Autism team (TCAT) meant that Matty was unable to access specialist advice and resources whilst in A&E or in the community.
7. The fact that the mental health assessment carried out during this second admission did not take into account the following:-
- The views and observations of the nearest relative, Matty’s mother.
- Matty’s preferred communication aids and in particular Matty’s communication book.
- The need for Matty to have an advocate present during the assessment and give consideration to the use of idiosyncratic language.
- The extent of Matty’s deteriorating mental state and their increasing risks in the context of their neurodivergence.
- The fact that Matty’s change of behaviour during the assessment may be due to:-
a) the fact that Matty had been given diazepam
b) the fact that Matty may have been able to mask their distress.
- Too much emphasis was placed on Matty’s presentation within the assessment itself.
8. There was a lack of discharge care planning documented after the assessment on 4th November 2022 particularly if Matty decided to leave before the morning. This led to confusion within the A&E department when Matty decided to leave the hospital.

Matty had struggled with their mental health throughout their adult life, but it wasn’t until 2019 that Matty was finally diagnosed with Autism, ADHD and Autistic Spectrum Disorder. However, they had never been sectioned under the Mental Health Act or had spent time as a voluntary patient in a mental health hospital.

Matty had moved to Brighton from Surrey in November 2021 having wanted to live independently. He was drawn to Brighton as they wished to be involved in the trans/non-binary community.

Matty’s mental health deteriorated during the summer of 2022 due to accommodation issues that they had been facing and issues with an online relationship. By 3rd September they were in crisis.

On 5th September 2022 Matty was admitted to A&E at the Royal County Hospital, Brighton. They remained within A&E, short stay ward, for 26 days awaiting a psychiatric bed. During this time no bed was found, and they were eventually discharged back home with support from the Crisis Home Treatment Team. Matty’s mental health had been affected by the unsuitability of the environment within A&E for someone awaiting an inpatient mental health bed.

Less than 5 weeks later Matty was again admitted to the A&E department at the Royal Sussex County Hospital on 3rd November 2022 in crisis. Their presentation fluctuated and this led to them being assessed under the Mental Health Act. However, they were not found to be detainable. They left the hospital shortly after the assessment and were sadly found hanging in the grounds of the hospital.

1. There is a lack of inpatient beds leading to unacceptable wait times in A&E for those suffering with their mental health who are awaiting beds. In Matty’s case a bed was not found for them within a 26-day period.
2. There being a national shortage of mental health beds in particular for Autistic patients and those who are transgender requiring a mixed ward.
3. The unsuitability of the environment of A&E as a holding place for those in need of a mental health bed. The environment in A&E as a holding place is not conducive for those suffering with Autism and/or who are neurodiverse. The environment in A&E can exacerbate their mental health.
4. There is a gap in services for those who do not meet the criteria for detention under the Mental Health Act but who are too high a risk to be sent home.
5. There is a significant wait time for referral to the Assessment and Treatment Service. Therefore, any therapeutic input is delayed, and this results in repetitive attendances at A&E when in crisis.
