7th March 2011
The Sheriff, having resumed consideration of the cause, Determines:-
1. (a) Chemical Pseumonitis

NOTE.
In this enquiry the Crown was represented by Miss Nicola Henderson, Procurator Fiscal Depute, Fife Health Board was represented by Mr Pugh, Counsel, Drs Satish Ramm and Ailsa Howie by Ms Donald, Solicitor, and Staff Nurse Ariff Khattak by Ms Watt, Solicitor. There were twelve witnesses who gave evidence over four days. The parties agreed certain evidence by joint minute.
The Facts and Circumstances surrounding Mrs Kirk's Death.
Submissions.
The Procurator-Fiscal Depute, Nicola Henderson.
She commenced by commenting on the devastating effect the death of Mrs Kirk had had on her husband. They had a very close relationship but Mrs Kirk in recent years had not kept great health. He last saw his wife alive on 23rd October 2008. The pain of reinsertion of the naso-gastric tube, complained of by Mrs Kirk a couple of days before her death, could not be regarded as affecting her death. She went on to detail the evidence led by each witness. She made criticism of the apparent lack of training in the insertion of naso-gastric tubes; the absence of written instruction to call for x-ray when no aspirate was obtained; the lack of contemporaneous notes; although information on reading x-rays was now in place for doctors commencing work, there was no check on their expertise. She did not ask me to include a finding under section 6(1) (c) of the Act while stating that there could have been the precaution of not having night feeding by naso-gastric tube and no replacement of the tube after 5pm. There could have been further training in reading x-rays. Similarly, she did not invite me to make a finding under section6 (1) (d). She invited me to make a finding under section 6(1) (e) of the Act as it was clear from the evidence that there had been significant improvements made by NHS Fife but the power point training in reading x-rays was simply left to the induction of new doctors with no check being made as to their competence. The proposed new protocol was still in draft format.
Ms Donald for Doctors Ramm and Howie.
She invited findings under section 6(1) (a) and (b). There was no evidence of any reasonable precaution which could have been taken whereby Mrs Kirk's death might have been avoided. She accepted that Dr Howie's ultimate decision to proceed with the naso-gastric feed was an error, which Dr Howie recognised.
Ms Watt for SN Khattak.
She also invited findings under section 6(1) (a) and (b).
Mr Pugh for Fife Health Board.
He, similarly, invited findings under section 6(1) (a) and (b). He made mention of the protocol in place at the relevant time and the adherence of staff to it. There had been training and there were now changes in the protocol and training. While there was no mention of going on to request an x-ray if no aspirate was found, this is what was done. Each junior doctor had training in a variety of departments. If unsure, the practice was to ask a more senior doctor. There was a new protocol envisaged in documentation which was described as an "entire multi-disciplinary pathway" and was in draft form and was presently out for consultation.
Conclusions.
1. Cause of Death.
Dr David Sadler conducted a post mortem examination of Mrs Kirk. She had had a large open wound to her abdomen from the previous operation and this wound had been healing well with no infection. In the autopsy she was found to have a large accumulation of infected fluid, empyema, in the chest cavity between the lung and the chest wall. There were several hundred millilitres. The lower area of her right lung was solidified due to pneumonia as a result of the aspiration of feeding material. There was a bacterial infection of the lung tissue. It was the inhalation of feeding material, which irritated the lung tissue, chemical pneumonitis. The empyema was a secondary effect of that. The aerated tissue had been filled with fluid which coagulated into the hardening of the lung. Mrs Kirk also had atherosclerotic coronary artery disease. He made a separate finding of this as a cause of death, as it was likely to have been a contributory factor in Mrs Kirk's death, although it was not the prime cause. As Mrs Kirk had heart disease, she was also susceptible to other conditions. He was unable to say whether Mrs Kirk would have survived, if she had not had coronary artery disease. The lung problem was the greater threat to Mrs Kirk, as she had had her heart problem for years.
2. Other facts relevant to the circumstances of Mrs Kirk's death.
I have made a finding under this heading as there have been changes to the protocol employed and training since Mrs Kirk's death. In doing so, I am not accepting that there was any other direct cause of Mrs Kirk's death than a clinical error of judgement in misreading the chest x-ray.
Protocol.
While there was no mention of calling for a chest x-ray, if no aspirate was found, in the existing protocol at the time, it was widely accepted by all the witnesses that this was done as a matter of course. SN Khattar and SNP Lawrie were both quite clear on this. An instruction to this effect has now been put in writing in the new protocol, which is being finalised.
Night-time feeding.
Within a couple of weeks following Mrs Kirk's death, there was a change in the practice of naso-gastric feeding of patients as there is no longer night-time feeding and, if a naso-gastric tube falls out, it is not to be replaced after 5pm. The reason for this is that there are fewer nurses, doctors and senior medical and radiological staff available during the night. Dr McKenzie, who was the Consultant in Geriatric Medicine, said that he had worked in England and Australia and the practice he had observed there was that, if a naso-gastric tube was out after 5pm, it would not be replaced until the following day.
Training in interpreting x-rays.
Doctors Howie and Ramm believed that, if the tip of the naso-gastric tube was below the diaphragm, the tube must be in the stomach. Dr Howie did not appreciate that, if the tube had gone into the lung, it could appear on the x-ray as below the diaphragm. Dr Wendy Robinson, who was in charge of the care for the elderly in Queen Margaret Hospital, said that she had checked the x-ray with Dr McKenzie and it was quite clear to her that the tip of the tube was at the base of the right lung and not in the stomach. Dr Ramm had correctly followed procedure in asking a more senior practitioner, Dr Howie, for her opinion. Dr Robinson confirmed that junior doctors were now trained in the interpretation of x-rays. Dr McKenzie, said that he would look for the tube going straight down the midline and left into the gastric area, the stomach. He saw that the tube was probably in the right lung. He also confirmed that training in interpretation of x-rays had been introduced by NHS Fife. I had questioned the quality of the x-ray image produced to the court. I thought it to be extremely hazy. Dr Alan Shepherd also said that the x-ray image was the poor. However, if the definition is changed on the computer screen, the image becomes much clearer. Dr Nicola Chapman, Consultant Physician, said that when she viewed the x-ray, she had difficulty in seeing exactly where the tube was. She raised this with the radiology staff and on their screen the image was much clearer. Dr Chapman was involved in the internal review following Mrs Kirk's death and produced the training package. There was now a much lower threshold, if one was unsure. The protocol was to speak to more senior staff or the radiology department. This would be done during the day. There was, however, no guarantee that a mistake might not be made in the future. She said that she would not have expected Dr Howie, given her level of experience and grade, to make this mistake. Dr Robert Cargill, Consultant Cardiologist, who convened the incident review, also expressed such surprise.
I make no criticism of the fact that the protocol document dealing with many other matters as well as those mentioned in this case, is still in draft form as there are many agencies, which require to approve it. It is not a matter to be rushed, particularly when the evidence was that the new protocol in respect of the matters raised in this case was being followed in any event. The use of power point images and directions to junior doctors in the training in interpreting the x-rays makes sense to me. No matter how comprehensive training may be, there is always the possibility of human error.
My sincere condolences go out to Mr Kirk.
