Challenge to validity of consent
18Part of the challenge to Mr Lane's decisions with respect to his wife's care was to posit alternative advice which might have been given to him, but was not. However, to make such a challenge relevant, it was necessary to demonstrate that such advice should have been given to him. The medical evidence did not support such a claim. In part that may have been because no such claim was pleaded. In any event, the case ultimately rested on the ability of the appellants to demonstrate some form of negligence on the part of the staff at the hospitals, including in relation to the information and advice supplied to Mr Lane.
19The appellants' expert was a Professor Fred Ehrlich. Although his report contained a list of his qualifications, it was not clear what speciality (if any) was relied upon in the present case: there was no curriculum vitae for him. (Dr Obeid, one of the experts called by the respondent referred to the "reports of Professor Fred Ehrlich (Rehabilitation Specialist)".) In answer to a direct question as to whether the care provided by the respondent was "negligent" Dr Ehrlich replied, in a report dated 16 April 2010 at p 4:
"One might consider three levels of management in a patient such as Mrs Lane.
(a) The most energetic would be active medical treatment, intravenous antibiotic therapy, vigorous chest physiotherapy and a concerted effort to 'cure' existing illnesses.
(b) Another possibility is to merely provide palliative measures such as keeping the patient comfortable, maintaining nutrition and hydration, providing adequate skin care to prevent bed sores, and attending to bowel and bladder function.
(c) The third approach is to 'do nothing' and let the patient die.
In my opinion, Mrs Lane's treatment might be considered to have been most correctly somewhere between (a) and (b) above.
Treatment (c) is euthanasia which, in my opinion, was not indicated in Mrs Lane's case."
20This opinion in relation to the critical question was not entirely responsive. Dr Ehrlich had earlier stated that he could find "no record in her files of her receiving antibacterial or antibiotic therapy". In fact she did. Two antibiotics, Ceftriaxone and Flagyl, were administered on 10 March 2007: Tcpt, 17/05/12, p 24(15)-(35). Those antibiotics were not continued because of the results of further investigations (blood and urine testing and a chest X-ray): Tcpt, 17/05/12, p 25(30)-26(28). Mrs Lane was also administered a low dose of morphine. Dr Ehrlich described that as "very odd indeed", because there was "no evidence that she had pain". He described morphine as a "well-known respiratory depressant", which is contraindicated in a person who has bronchopneumonia. There was reference to pain and discomfort in the hospital notes. Dr Coupe, the registrar at Lismore Base Hospital who saw Mrs Lane on almost every day that she was in the hospital, said the morphine was initially prescribed for pain, agitation and distress: Tcpt, 21/06/12, p 70(17). Dr Laird, a visiting medical officer who first saw Mrs Lane on 15 March, described the doses of morphine administered on 10, 11 and 12 March as not "at all excessive": Tcpt, 17/05/12, p 17(30).
21Dr Ehrlich's somewhat vague criticisms were rejected by Dr John Obeid, a consultant physician and geriatrician called by the respondent. His only criticism was that the hospital could have offered physiotherapy and occupational therapy services, although he noted it was possible that the staff elected not to pursue this option due to Mrs Lane's "immobility and evidence of pain": Report, 18 September 2010, par 2.4.6.2. He did not suggest that anything followed from the absence of such services and, in a further report, expressly stated that it did not cause "any material difference to her care or outcome": Report, 12 March 2012, ("second report") par 2.2.1.
22Dr Obeid noted that Mrs Lane had been seen by a speech pathologist on 15 March who had formed the view that it was "unsafe for any oral intake and recommended nil by mouth": second report, par 3.5.1. He was critical of the appellants' attempts to continue to feed their mother. That speech pathologist, Ms Kostal, was unable to engage Mrs Lane's attention in order to complete a swallowing assessment. Nor did she observe any spontaneous swallowing on that occasion: Tcpt, 17/05/12, p 95(1). That was consistent with Dr Coupe's observations at the same time: Tcpt, 21/06/12, p 65(47). A further assessment by another speech pathologist, Ms Lucks, on 22 March produced the same outcome. Mrs Lane did not make eye contact or respond to any verbal or tactile stimulation to enable a swallowing assessment to be done. Nor did she show any spontaneous swallowing: Tcpt, 18/05/12, p 5(5)-(6).
23With respect to the comment by Dr Ehrlich relating to morphine, Dr Obeid noted (consistently with Dr Laird's evidence) that the dose was "very small by any standard": second report, par 3.7.1. With respect to the suggestion that there was "no evidence she had pain", he referred to the medical notes on four days which recorded indications of pain. He disagreed that morphine was a respiratory depressant at the doses administered to Mrs Lane: par 3.7.5. Nor did he see any evidence of respiratory depression in the hospital notes.
24With respect to the suggestion that Mrs Lane was not provided with nutrition, Dr Obeid noted that such a view ignored the fact that she had been assessed as "unsafe to swallow" and that she was administered intravenous fluids and dextrose. He rejected the proposition that her treatment could properly be described as "euthanasia", that being the criminal and deliberate killing of a patient by means of a legal dose of a drug, or the wilful denial of access to appropriate and reasonable medical treatment. He saw no evidence supporting the validity of such a description of the treatment of Mrs Lane: he described the care given to Mrs Lane as "appropriate palliative care": at par 3.10.4.
25The opinions of Dr Obeid that the treatment of Mrs Lane was appropriate and demonstrated no negligence were supported by Dr John Raftos, an expert in emergency medicine. After setting out in detail the history of Mrs Lane's condition recorded in the hospital notes, Dr Raftos concluded, in a report of 2 September 2011:
"Mrs Lane had progressive vascular dementia which had caused her to become totally dependent on others for all of the activities of daily living. She was incontinent of urine and unable to communicate verbally. When she presented to hospital with decreased level of consciousness, doctors, after performing appropriate investigations, reasonably and appropriately advised her family that she was at the end of her life and that comfort measures only were indicated."
26Drs Obeid and Raftos were unshaken in their opinions, in giving oral evidence.
27By contrast, Dr Ehrlich was hesitant in his critique when cross-examined. When it was pointed out that Mrs Lane had received antibiotics on two occasions, he agreed that he had "missed one dose" and that he was not familiar with another drug (in fact an antibiotic) which was administered to her: Tcpt, 20/06/12, p 47. When it was further put to him that a microbiology report indicated no continuing infection, explaining why the antibiotics had been discontinued, he replied (p 48(45)):
"No, no you can't conclude that. That maybe the case but the fact that there's no growth can be due to many, many things, the sample was not kept the right way, was not plated out the right way. You very often get no growth where there should be growth, but you're right, it could be that she had no urinary infection, yes."
28Dr Ehrlich was asked (p 49(41)):
"Q. Do you say that it is more likely than not that she could have returned to her premorbid state?
A. Well, it's not right for me to speculate about that. I don't know how long she was hypoxic. I don't think if she was hypoxic. I don't know how bad she was at the time. I don't know how long it took for her to get better. It may have done permanent damage, it may not have.
Q. Is it fair to say it's just not possible to know?
A. Well, not for me to know, no."
29When further asked about his belief that she was "not terminal" he replied (Tcpt, p 50(30)):
"At the time - her final illness was diagnosed to be pneumonia. She wasn't - from what I can see she wasn't treated for pneumonia. Presumably because the clinicians made a decision that it is not worth treating her. That there can be no useful outcome, hence no treatment, that's fair enough. If that's what they thought, that's what they should do."
30At p 56(45) the following exchange occurred:
"Q. Well isn't that one of the reasons why you offered the treatment was not correct, there was no investigation of these things?
A. Well there in fact was no treatment. From what I can see this lady was very ill. There was no active treatment. Obviously the decision was that we let this person die, and that was done. Now was it the right thing to do, well if anybody if everybody is satisfied that there was absolutely no prospect of any useful future then it was in our treatment [sic]. But I did not really get the feeling that all these options had been adequately covered. But you know I can be wrong.
...
Q. But you're not suggesting that, are you, that Mrs Lane was likely to make a recovery are you?
A. I don't know is the answer.
...
A. ... so it depends really on how the clinician sees the situation. If they really thought that there is no hope for this lady then I suppose they could have done nothing else. Yes, that's right.
31The trial judge, after an exhaustive analysis of the evidence, came to the following conclusions:
"[333] Mr Lane's view of how his wife was treated is valuable, the test must be an objective one in accordance with widely accepted professional practice. However I do not think that Mr Lane's view of how Helen was treated is misplaced in any way. The legal and undisputed fact is that he was Mrs Lane's next of kin and her legal guardian at all relevant times. That doesn't mean that if he accepted a course of conduct on the part of the hospital, that conduct escapes supervision. There are two bases to do so. The first is whether the conduct was necessary and appropriate. The second is whether it was properly explained to Mr Lane in terms he could understand. ... The treatment risks or outcomes relevant to Mrs Lane were, I am satisfied, adequately explained to Mr Lane and others in the family and that he understood those explanations despite the no doubt emotional experience he was undergoing.
...
[335] However the plaintiffs have been unable to establish that even if all the things they say should not have been done were done and if all the things they say should have been done were not done, it was more likely than not that Mrs Lane's outcome would have been meaningfully different in the short term, that is that Mrs Lane wouldn't have died at or about the time she did in fact die."
32Those conclusions were fully justified on the evidence. Indeed, and possibly more importantly, apart from the ambivalent and imprecise opinions of Dr Ehrlich, the evidence that the steps taken in the hospital were both reasonable and appropriate in the circumstances was overwhelming. Most of the doctors who treated or were responsible for Mrs Lane's treatment at Lismore Hospital gave evidence. They were Dr Seneviratne, a resident medical officer, Dr Burrell, a staff specialist who went on leave on 14 March, Dr Coupe and Dr Laird. Each was questioned at length by both appellants.
33Dr Seneviratne saw Mrs Lane shortly after her admission. He described her clinical condition as "very bad": Tcpt, 16/05/12, p 31(24). Without the oxygen that was being supplied to her at that time she most probably would have died: Tcpt, 16/05/12, p 29(32). Dr Burrell considered Mrs Lane to be "in a palliative situation from the time" he first saw her on 12 March: Tcpt, 18/05/12, p 24(45). By 14 March, the day Dr Burrell went on leave, he thought Mrs Lane's condition was such that she was going to die: Tcpt, 18/05/12, p 28-29. Dr Coupe described his assessment of Mrs Lane when first admitted as a "gravely ill woman with no reversible causes": Tcpt, 21/06/12, p 60(46). He saw her every day and whilst there were very subtle changes in her condition "unfortunately nothing of any meaningful improvement". He said that if she had improved "we would have changed everything": Tcpt, 21/06/12, p 67(3). Dr Laird, who first saw Mrs Lane on 15 March, considered that in the way she presented it was "[a]bsolutely likely" that she was going to die: Tcpt, 17/05/12, p 31(45). He agreed that her prognosis was poor and that it was not appropriate to be "aggressive in her care": Tcpt, 17/05/12, p 15(26). The evidence of all of these clinicians who treated Mrs Lane at Lismore Hospital was that she was at the end of her life. That being their considered assessment, Dr Ehrlich agreed that "they could have done nothing else" than provide palliative measures to keep her comfortable.
