The failure to perform an MRI brain scan
41 On the applicant's arrival at PIH late on the afternoon of 14 June the consultant paediatrician at PIH, Dr Mary Baki, assumed clinical responsibility for her treatment.
42 Dr Baki made a provisional diagnosis of herpes encephalitis, and the evidence is that by that time the applicant was responding well to Acyclovir, the herpes medication recommended by Dr George and continued by Dr Baki. PIH performed a CT scan of the applicant's brain on 15 June, which was assessed as unremarkable. The CT scan noted though that a normal brain scan does not rule out the possibility of an acute and encephalitic process and, if clinically warranted, a follow-up contrast enhanced computed tomography scan (CECT) is recommended.
43 Ms Kanis raised the question of when an MRI would be performed in correspondence with Dejan Lukic of the Australian Government Solicitor on 17 June. On 18 June Mr Lukic emailed Ms Kanis stating that PIH :
…confirmed that a CT scan was done instead of an MRI in [the applicant's] case, because an MRI scan would require at least 30 to 45 minutes of [the applicant] lying sedated in a claustrophobic environment. Further, PIH has advised that such prolonged sedation can be unsafe in a child recovering from encephalitis.
It appears that Mr Lukic or his instructors in the Department had been informed of this by PIH. As I explain, however, this was not the case.
44 Ms Kanis continued to press the matter of an MRI with Mr Lukic over the ensuing days. On 28 June 2018 she provided an expert medical opinion she had obtained from Dr Harbord, dated 27 June 2018. Dr Harbord was admitted as a fellow of the Royal Australasian College of Physicians in 1984 and then undertook advanced training in paediatric neurology in London, UK, and in Toronto, Canada. Since 1990 he has been a visiting Paediatric Neurologist at Flinders Medical Centre. He is a lecturer in the Paediatric Department, Flinders University, the Senior Neurologist for Disability SA, and he has published over 50 papers on various neurology topics.
45 In relation to the requirement for an MRI Dr Harbord said, in summary, that the literature confirms brain injury as a result of herpes encephalitis is relatively common. In his medical opinion, the standard of care required the applicant to undergo an MRI under anaesthetic as soon as possible, which procedure is regularly and safely undertaken in Australian hospitals. In Dr Harbord's view, given the potential for cognitive impairment and long-term deficits in the frontal and temporal lobes arising from herpes encephalitis, and the problem of detecting these changes in a 2-year-old, the standard of care would also require ongoing monitoring. Dr Harbord considered the opinion expressed by the applicant's treating clinician at PIH that she could return to Nauru in this context reflected a "lack of expertise and familiarity with the potential neurological consequences" of the applicant's condition.
46 In a supplementary opinion dated 1 July 2018 Dr Harbord expanded on the need for the applicant to have an MRI as soon as possible, as follows:
The standard of care in Australia is that an MRI is conducted within a week of the onset of herpes encephalitis.
It is important to do the MRI as soon as possible to increase the chances of seeing the signal changes in the brain which represent the areas of inflammation. The longer you wait to do the MRI the more likely it is that the areas of inflammation will disappear.
As such, a delayed MRI scan may look normal but this does not mean that there has not been some patchy scarring of the brain and brain damage. In my opinion the MRI should be conducted as soon as possible on this child and ideally within one week.
An MRI will provide an indication as to the clinical outcomes for the patient. If multiple areas of inflammation are present, then the patient is more likely to have epilepsy, memory loss, language loss and loss of general cognitive function.
An early MRI allows treating medical practitioners to know what to anticipate in the client's treatment. Without an MRI, or with a delayed MRI, greater clinical monitoring is required. A failure to undertake an MRI means that there is much less information about the longer term outlook for this child and the treating medical practitioners are less prepared about what they will need to treat in the future.
47 It is uncontentious that PIH did not perform an MRI. At the hearing on 29 June counsel for the respondents informed the Court that:
…it wasn't for want of equipment or a specialist that an MRI has not been done so far. It was simply a judgement made…by the doctors in PNG that it wasn't necessary.
Counsel also said:
Well, all that the applicant so far has suggested is that there needs to be an MRI. There is an MRI on PNG. There is a person who can conduct it. The judgement was made by the treating doctors that it wasn't necessary at this stage.
That was not correct.
48 At the hearing on 3 July, counsel informed the Court that although he was still instructed that an MRI scan was unnecessary, it had recently become clear that PIH was not in fact equipped to carry out an MRI scan safely on a child of the applicant's age. According to Ms Holben's affidavit, on 30 June 2018 PIH for the first time advised the Department that it "does not presently have compatible anaesthetic equipment and ancillaries to sedate a child while conducting an MRI". She said that steps are now being taken by PIH and ABF to obtain the necessary anaesthetic equipment to perform an MRI on the applicant within the next seven days.
49 There is a strongly arguable case that, together with the other matters to which I refer, the failure to perform an MRI on the applicant shows a failure to provide her with adequate healthcare. The respondents concede that an MRI is a necessary test and, notwithstanding that the applicant has been in PIH since 14 June, she has not been provided it. For the purposes of the application I accept Dr Harbord's opinion that an early MRI is important in order to increase the chances of being able to discern any changes in the brain and allow treating medical practitioners to know what to anticipate in the applicant's treatment.
50 Unfortunately, the applicant is now in the position, through no fault of her own, that an MRI has not been performed and her treating doctors may have greater difficulty in understanding whether she has suffered a brain injury and if so to what level, and monitoring and treating her condition. I am not prepared to allow a further delay of seven days on top of what has already occurred. I am also reluctant to allow the applicant to be the first child to undergo an MRI under sedation at PIH, with the hospital having been rushed into getting appropriate equipment and training appropriate staff.
