Investigation and inquest
On 24th April 2014 I commenced an investigation into the death of Gerald Trevor WERRETT, aged 67. The investigation concluded at the end of the inquest on 25th July 2014. The conclusion of the inquest was that Mr Werrrett died due to:
Ia Bilateral bronchopneumonia
Ib Chronic obstructive airways disease
II Ischaemic heart disease
His death was contributed to by a misplaced chest drain and the conclusion given was natural causes contributed to by neglect.
Circumstances of the death
Mr. Werrett was admitted to hospital on 28th February 2014 with infective exacerbation of his chronic obstructive airways disease together with a number of co-morbidities.
During his admission he required a number of chest drains to be inserted to treat his condition.
On 31st March 2014 he required a further drain to be inserted and two chest x-rays were taken. It was clear from the evidence and indeed not disputed that the chest x-rays were inverted and mislabelled which resulted in the registrar misinterpreting the one x-ray that she looked at (she did not look at both), this resulted in a chest drain being put in the left side when in fact the pneumothorax was on the right. Mr. Werrett subsequently required a chest drain to be inserted on the right as well.
Mr. Werrett's treating consultant gave evidence and said that the chest drain was wrongly inserted, having two chest drains caused pain and made him less mobile with cough difficulties, the staff clearly tried desperately to rectify the situation but that the second unnecessary drain had an impact and a contributory factor to his death.
The incident on 31st March 2014 resulted in a never event and the Trust have now rolled out a safety check list to be completed prior to the insertion of a chest drain together with guidelines for the insertion of chest drains.
Coroner’s concerns
Chest drains are inserted by a number of medical disciplines and clearly this event has shown that basic failures can have catastrophic consequences, the areas identified during the inquest included:
1. A lead anatomical marker was not used when taking the chest x-ray
2. Both chest x-rays were incorrectly labelled, and this error was not identified by the clinician
3. The chest x-ray that was looked at was misinterpreted
4. Both chest x-rays were not considered.
5. The cardiac silhouette was not interpreted correctly
6. Mr. Werrett was not examined prior to the insertion of the chest drain.
North Bristol NHS Trust have clearly learnt a valuable lesson following this incident and have devised a safety check list and guideline which could be of assistance to the wider medical community. North Bristol NHS Trust have indicated that they would be willing to share the check list and guideline which if implemented could avoid a similar event happening again.
