 Peter Malcolm Thomas was aged 78 and had developed peripheral vascular disease which 
led to necrotic and subsequently gangrenous toes. This became osteomyelitis of the foot, 
and a wider spread, more significant infection. On 15th January 2022, Peter collapsed and 
was  taken  into  the  Royal  Glamorgan  Hospital,  Llantrisant,  where  he  was  treated  with 
antibiotics and fluids. Sadly, his condition deteriorated significantly, and his infection became 
a systemic sepsis until he became unconscious and sadly died on 19th January.  

Although Peter was given diazepam as a sedative, a treatment he did not require, on 
balance it did not contribute more than minimally to the development of 
bronchopneumonia, from which he ultimately died. 

 His cause of death was found to be: 

1a   Bilateral Bronchopneumonia 

1b   Osteomyelitis of the Foot 

1c   Peripheral Vascular Disease 

 II     
CIRCUMSTANCES OF THE DEATH 

It was identified early upon admission that Peter was likely suffering from a serious infection as well 
as delirium. A clinician undertaking an examination took an account from Peter which led him to 
instruct the CIWA protocol to be used, due to information provided by Peter and some concerning 
signs and symptoms. 

In fact, CIWA was a red herring, as Peter was not in alcohol withdrawal, he was confused and 
delirious and gave an erroneous account of having been drinking. The signs and symptoms he 
exhibited were more likely due to the serious infection taking hold of him and leading to shaking, 
sweating, agitation and anxiety. His false account was likely due to confusion or delirium. 

4 

No collateral information was sought from medical records, nor from capacitous family (who would 
have been available by phone very easily) and when Peter’s symptoms scored against the CIWA 
protocol, he was given 80mg of diazepam over 6 hours. He did not require this drug and at 78 with 
serious comorbidities and a developing sepsis, his metabolism of it was likely hindered. 2 doses of 
the antidote were subsequently given but Peter did not regain consciousness. He went on to die 
from pneumonia. 

The Inquest focused upon:- 

a. The use of CIWA with Peter at all 

b. The dosing suggested within CIWA 

c.  The effect of the diazepam and its contribution to Peter’s death 

CORONER’S CONCERNS

Coroner’s Office, The Old Courthouse, Courthouse Street, Pontypridd, CF37 1JW 

 
  
 During the course of the inquest the evidence revealed matters giving rise to concern. In 
my opinion there is a risk that future deaths will 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)   I am concerned that the CIWA protocol is something of a blunt instrument, not at all 
nuanced to take account of for example, advancing age and different metabolic rate, 
delirium and confusion and lack of collateral evidence 

(2) Clinicians without further guidance on its use, will continue to be at risk of implementing 
the CIWA protocol and prescribing sedatives at significant dose and frequency when it is 
not required, which presents risks of over-sedation and its consequences, particularly in 
the elderly and potentially delirious cohort, based upon pattern recognition rather than 
reliable evidence 

(3) the NICE guidelines on the management of alcohol withdrawal do not explicitly deal 
with the situation here, which could well recur and lead to future deaths 

ACTION SHOULD BE TAKEN 

In my opinion action should be taken to prevent future deaths and I believe you and your 
organisation have the power to take such action.

Dear Ms Knight,

Re: Regulation 28 Prevention of Future Deaths Report in respect of Peter Malcolm
Thomas

I write in response to your report of 3 September 2025, regarding the very sad death of Peter
Malcolm Thomas. I would like to express my sincere condolences to Mr Thomas’s family.

The patient safety leads at NICE have carefully considered the content of your report and
the matters raised, and any action that we should take as a result.

Response to the matters of concern

I note that your matters of concern relate to the NICE guideline entitled Alcohol-use
disorders: diagnosis and management of physical complications (reference CG100), and the
recommendations within the guideline.

The guideline includes the following recommendations:

1.1.2 Assessment and monitoring

1.1.2.1 Healthcare professionals who care for people in acute alcohol withdrawal should be
skilled in the assessment and monitoring of withdrawal symptoms and signs. [2010]; and

1.1.2.3 People in acute alcohol withdrawal should be assessed immediately on admission to
hospital by a healthcare professional skilled in the management of alcohol withdrawal.

Our opinion is that these recommendations adequately convey the need for professional skill
in the assessment and monitoring of patients and in the application of our recommendations.

NICE

www.nice.org.uk  | nice@nice.org.uk

 Based on the limited information available to us, we cannot see that the clinicians caring for
Mr Thomas confirmed a diagnosis of alcohol withdrawal, and so cannot conclude that these
recommendations were followed.

A further recommendation in the same guideline, which you have referred to, states:

1.1.2.2 Follow locally specified protocols to assess and monitor patients in acute alcohol
withdrawal. Consider using a tool (such as the Clinical Institute Withdrawal Assessment -
Alcohol, revised [CIWA-Ar] scale) as an adjunct to clinical judgement. [2010]

The CIWA-Ar protocol is a validated 10-item assessment tool that can be used to quantify
the severity of the alcohol withdrawal syndrome, and to monitor and medicate patients
throughout withdrawal.

This recommendation suggests the CIWA-Ar as a possible option, in addition to the clinical
judgment of the healthcare professionals who have responsibility for caring for their patient.

Status of NICE guidelines

As background regarding the status of NICE guidelines, it is important to note that the
recommendations in our guidelines represent the view of NICE, arrived at after careful
consideration of the evidence available. When exercising their judgement, health
professionals and practitioners are expected to take NICE guidelines fully into account,
alongside the individual needs, preferences and values of their patients or the people using
their service. It is not mandatory for the NHS to apply the recommendations, and the
guideline does not override the responsibility for clinicians to make decisions appropriate to
the circumstances of the individual, in consultation with them (and their families and carers
or guardian where appropriate).

Responsibility for decisions on the most appropriate treatment stays with individual
clinicians. NICE guidelines are a practical tool to be used in conjunction with and not as a
substitute for clinical judgement.

Action to be taken

In the case of the CIWA-Ar scale, this protocol was not produced by NICE, and so we are
unable to amend it, but it is appropriate for us to consider whether it is still relevant for NICE
to recommend its use as an assessment and monitoring tool in our guidance.

Decisions as to whether NICE will update existing guidance are overseen by an integrated,
cross-organisational prioritisation board, chaired by NICE’S chief medical officer.

The prioritisation board has previously considered the topic of alcohol withdrawal, and
considering the volume of new evidence in this area, and the time since our guidance on this
topic area was originally published, the board concluded that an update should be
considered.

This topic will therefore be looked at again by the prioritisation board in approximately
February-March 2026, to determine what changes, if any, are needed to the guideline. This
will include consideration of pharmacological treatment for acute alcohol withdrawal to
optimise treatment options for patients.

Page  |  2

 The decisions taken as a result will be published on our website at www.nice.orq.uk
following the prioritisation board’s meeting, and if any changes are made to the guidance,
this will also be published so that it is freely available to all.

I hope that the information above is helpful and would like to reiterate my sincere
condolences to Mr Thomas’s family.

Yours sincerely,

Chief Executive
