Report summary

Mr. Christopher Summerhayes was found deceased at his home address after a significant medical history including double scoliosis, treatment-resistant schizophrenia and a complex regime of around 12 daily medications. The concerns included the prescription of clozapine alongside other medications, substantial weight gain and possible effects on his cardiovascular system, as well as a possible familial lipid disorder. The inquest concluded that the medical cause of death was ischaemic heart disease, with a narrative determination referring to atypical early-onset coronary artery atherosclerosis and complex prescribed medications.

PFD Monitor interpretation
Failure to distinguish clozapine overdose signs from unresolved schizophrenia symptoms
Wider context from the report
“(1) In relation to Christopher Summerhayes, Clozapine was prescribed as a concomitant medication alongside approximately 11 other drugs including another anti-psychotic medication. Either alone or interaction with other prescribed medication, a large increase in weight occurred to >101kg (BMI 33.1) (reported side effect of clozapine) which had a ‘knock-on’ effect for his cholesterol and lipid levels and cardiovascular system. The usual dose is 200-450mg daily with the maximum dose being 900mg (BNF) which does not consider concomitant medications. Signs of prescription overdose include collapse and hallucinations which could be mistaken for unresolved symptoms of schizophrenia i.e. lack of drug efficacy encouraging dose increase. Blood levels of clozapine may rise in response to smoking cessation which Mr. Summerhayes had advised we was commencing. (2) He may have suffered from a familial lipid disorder (present in other family members) which had it been confirmed would likely to have contraindicated Clozapine. ”

PFD Monitor interpretation
Failure to review an initial diagnosis when the patient deteriorates
Wider context from the report
“A RCA revealed a number of failings by the Trust including in respect of some matters that had been previously raised by the Care Quality Commission and required action. The failings identified by the Trust and those found by the Jury included; inter alia failing to document important clinical findings for example the failure to document the rash that Tom presented with when he arrived at AED which was not recorded at triage. The failure to escalate the NEWS (National Modified Early Warning Score) in a timely manner to medical staff and to repeat observations hourly in accordance with the NEWS policy. The failure to complete a full “PIT STOP” review, the failure to review the initial diagnosis of gastroenteritis when Tom’s condition continued to deteriorate, the failure of clinical staff to handover clinical concerns to each other and to medical staff including face to face handovers, the failure to escalate monitoring and management appropriately in particular following receipt of the first set of grossly abnormal blood results, the failure to administer antibiotic therapy until 23.00 hrs this even when Tom’s condition continued to deteriorate and the rash that he presented with began to spread and appeared to change in both colour, size and location during which time Tom was becoming increasingly unwell, he had been a fit and well 28 year old prior to his attendance in AED. There was also an admitted failure to escalate appropriately and to convey the magnitude and severity of Tom’s condition and deterioration to the Critical Care Team, who described him as being “in extremis” when the Critical care doctor arrived shortly after 23.00hrs. The care and treatment from 2300hrs onwards on 18/02/2017 was regarded as wholly appropriate but sadly Tom did not recover and he died on 20/02/2017. Aintree University Hospital have put an action plan in place to address the failings identified within the RCA however such is the concern of the Coroner pertaining to the training needs of clinical staff (doctors and nurses) in respect of the identification and treatment of sepsis and meningococcal sepsis in particular that the Coroner requires a report and action plan which clearly identifies a systematic, consistent and comprehensive ongoing training programme which identifies not only the training plan that will be implemented across the Trust but also how the training plans implementation will be monitored in respect of consistency of approach, compliance and effectiveness. The Trust has produced a number of action plans on previous occasions following Care Quality Commission Reviews, however, some of the failings identified in the issues touching the death of Tom Cribley have also been identified on previous occasions. Robust monitoring and ownership of the training programme, implementation and review is required from the very top of the organisation up to and including the Trust Board. This leadership and ownership from the top will be fundamental to the achievement of meaningful and sustained improvements in the provision of education and training in this most challenging clinical area. ”

Report summary

David Michael Little was admitted to hospital with abdominal pain and a suspected small-bowel mass. His condition worsened, and a scan revealed a blockage caused by ischaemic bowel; delays in scanning, reporting, and insertion of an NG tube meant that surgery was considered when it was deemed too late. The report raised concerns about poor record-keeping, lack of a clear diagnostic and monitoring pathway, failure to recognise the seriousness of bowel obstruction, and poor communication among staff and with the family.

Wider context from the report
“(1) The doctors and nurses at the prison failed to properly diagnose, treat and care for Mr Colton in that they assumed that the diagnosis of mechanical back pain was accurate and took no steps to revisit the diagnosis or to escalate his treatment despite his obvious continuing decline. The failure to consider alternate diagnosis led to him missing his developing cancer and which may, therefore, have contributed to his early death. ”

Whilst there are a number of learning objectives for the day, principally, staff were asked to be open and to be curious in clinical situations. I understand from my Deputy Head of Healthcare at HMP Long Lartin that staff still talk about the learning generated from this case and in the last week there has been an example of staff raising an issue and being encouraged to consider alternative options.”

Michael James SWEENEY · Prevention of Future Deaths report

This summary was generated using AI from the published report. Please read the original report for the complete account.

Report summary

Michael James Sweeney died after taking cocaine and becoming extremely agitated; he was transported to hospital by police after an ambulance was not sent within the target time. He was restrained prone until sedation was effective, then arrested and died less than two hours later. The principal concerns were the inconsistent use and understanding of the term “excited delirium”, the risk of missing other medical causes of extreme agitation, and ambulance-service prioritisation of such emergencies.

PFD Monitor interpretation
Reliance on “excited delirium” as an apparent diagnosis risking missed organic causes
Wider context from the report
“Police officers had clearly been trained in the condition described to them as excited delirium. The training was effective in facilitating their understanding of Mr Sweeney’s condition as a medical emergency. However, this term is not widely used in this country, and neither ambulance, nursing nor even some of the medical staff had heard of it in April 2011. It would be possible to give ambulance and hospital personnel an understanding of the term excited delirium. However, given that this describes a medical condition, it seems more logical for the police to follow health services in this, rather than the other way round. Moreover, although it did not happen in Mr Sweeney’s case, there could be situations where a person exhibits extreme agitation that is not related to an acute drug psychosis. There is the potential for an organic cause to be missed because of reliance on that term as an apparent diagnosis. Extreme agitation can be caused by conditions such as a bleed on the brain, sepsis from infection (e.g. meningitis), or a diabetic coma. From the evidence I heard, the safest and most effective way to deal with a person exhibiting such an acute behavioural disturbance seems to be simply to use the term “extreme agitation”. This describes the constellation of symptoms without purporting to diagnose the cause. 1. Such an approach would require the Metropolitan Police Service simply to amend the training it currently delivers, to describe the condition as “extreme agitation” rather than “excited delirium”. 2. The take home message that the condition is a medical emergency should still be part and parcel of the training, in just the way it is now. 3. This training would also need to be delivered in some form to police control staff, so that they recognise the importance of the term when an officer uses it, and pass this on to the ambulance service. 4. Finally, it would require London Ambulance Service to amend its protocols and training to recognise extreme agitation as a medical emergency and prioritise appropriately. ”

“Secondly, both national and Metropolitan Police training on the correct terminology to use have in fact already moved on since the date of this incident. Though the ‘constellation of behaviours’ has at various points in the developing knowledge about it’s causes and effects been known (inter alia) as ‘cocaine psychosis’, and ‘excited delirium’, since 2010 the generally recognised phrase within UK police texts has been ‘Acute Behavioural Disorder’ (‘ABD’). This phrase was chosen to provide exactly the “ ‘precision without ‘diagnosis’ “ you indicated would be a necessary element of any common terminology adopted.

Meanwhile, the development of a detailed and documented joint agency call-handling protocol with our partners at London Ambulance Service, contained within the new Memorandum of Understanding, gives both ‘First Responder’ agencies a common wellspring of guidance to draw upon, a robust channel of communication where ABD is suspected, and clarity regarding the expectations each agency can have of the other’s response in these circumstances. It is now important that staff in emergency departments are also made aware of this condition and its management.”
