What happened
Sharon Wall, 53, from Gloucester, was a healthcare assistant at Wotton Lawn Hospital, the 88-bed acute mental health hospital run by 2gether NHS Foundation Trust. At about 07:30 on Wednesday 9 July 2014 she was attacked in the inpatient unit.
Colleagues helped her and she was taken to Gloucestershire Royal Hospital, where she died a short time later. The patient accused of killing her was Ryan Matthews, who was already serving a life sentence for a double murder in 1983 under a previous name.
The outcome
Matthews was charged with murder at Cheltenham magistrates’ court and remanded in custody. He pleaded guilty in December 2014 and was given a whole-life order.
At the time of the sentencing the Health and Safety Executive was investigating Wall’s death, according to BBC reporting.
What went wrong
Nobody established how the knife reached the ward. Police and NHS investigations did not find out, and the trust’s chief executive, Shaun Clee, said that staff had no idea where Matthews got it. It was not one of the sharps kept on the unit, which he said were controlled.
The trust was changing its search policy at the unit. BBC reporting after the conviction records that it had identified areas where it could learn and do additional things by revising and enhancing its search procedures. That is an admission that the search regime on the day was not the one the trust wanted.
In 2012-13, 679 staff were assaulted at the trust out of 2,346 declared staff, according to the NHS assault figures reported at the time.
Matthews was due to be moved to Ty Catrin Hospital in Cardiff on the day he killed her.
What it teaches
The attack fell at the end of a night shift, when a ward is finishing one set of observations and starting another. The sources do not say whether Wall was working alone, and this page does not claim that she was. What they show is one staff member at the hour when the ward’s attention is divided.
Sharps control is one part of a search policy. If a patient can bring a weapon onto a ward from outside, the search at the door is the control that matters, and finding every weapon is not the standard to set.
The other lesson is the near miss. A trust that knows its assault numbers and is rewriting its search policy already has the information. What it needs is a route for staff to report a missing control without the report going into a file.
Questions for the room
- Where is your attention split: shift start, end, handover, breaks? What is the rule for cover then?
- If you could not account for every potential weapon in your workspace, what one change would you ask for tomorrow?
- How does a near miss on your ward get raised and answered, and who closes it?
- When a patient is being transferred, what changes on the ward that day, and who is watching for it?
Evidence and limits
Confidence: confirmed. Three sources were read: BBC News on 10 July 2014, the Guardian on 12 July 2014 and BBC News on 10 December 2014. They establish the date, time, hospital, charge, plea and whole-life order. They do not carry the HSE’s findings. Our case record adds that a later HSE review reported no breaches by the trust. The sources read here record only that the HSE was investigating, so that conclusion is not established on this page. Nothing in the sources describes the ward’s staffing at 07:30.
Our lone working training covers handover and cover in services that run around the clock.
