Medical treatment and assessments
37The plaintiff tendered a number of medical reports without calling any supplementary oral evidence from the authors of those reports: Exhibit "B". The defendants took a similar course by tendering a bundle of medical reports and records: Exhibit "D1: 2"
38Whilst that course was open to the parties, and it is one that is provided for in the rules and applicable Practice Notes, where conflicting medical opinions are presented, based on differing histories that have to be reconciled and resolved, as is the case here, such an approach can lead to difficulties and a degree of apparent arbitrariness in assessing which of the opposing medical opinions should be preferred over others. The same comment applies to unexplained and unexplored entries contained in tendered copies of medical records produced on subpoena.
39Dr Soliman's records indicate that before 2008 the plaintiff was being seen in his general practice for depression, family problems and anxiety disorders. The detail of those matters was not explored with the plaintiff.
40The plaintiff tendered a series of 5 Workcover medical certificates that were provided by treating general practitioners from within the practice of Dr Soliman for the period 6 June 2008 to 3 January 2009. Those documents certified various periods during which the plaintiff was unfit for her usual work duties. The first of those certificates identified the plaintiff's initial problems to be neck pain and mild traumatic brain injury with post-concussion syndrome. The second certificate referred to those matters and added a reference to a back injury and to the plaintiff suffering from post-traumatic stress.
41Immediately following the accident, the plaintiff had an initial period of one month off work. This was later followed by a further 2 months off work between September 2008 and November 2008, and then a further week off work in January 2009, as well as some other sporadic absences.
42On 1 July 2008, the plaintiff attended a follow-up assessment at the Westmead Brain Injury Unit. At that time, Dr Kathleen McCarthy identified that the plaintiff had suffered a brief period of loss of consciousness and mild traumatic brain injury with associated post-traumatic positional vertigo, which was expected to settle.
43Dr McCarthy also identified the presence of post-traumatic stress disorder ["PTSD"] in the plaintiff. Treatment by way of psychological counselling and cognitive behavioural therapy ["CBT"] was recommended to the plaintiff for these problems. At her first follow-up consultation with the plaintiff, Dr McCarthy noted that at that stage, the plaintiff was already scheduled to see an orthopaedic surgeon for the management of the spasms that Dr McCarthy had observed to be present in the paraspinal muscles in the plaintiff's cervical spine.
44Dr Soliman had by that stage referred the plaintiff for assessment and treatment by Dr Guirgis, an orthopaedic surgeon. Dr Guirgis subsequently issued two reporting letters to Dr Soliman. These were respectively dated 22 July 2008 and 18 December 2008.
45It should be noted that the two letters received into evidence from Dr Guirgis, and which formed part of Exhibit "B", are not expert opinions that have been prepared in accordance with UCPR r 31.23. They are simply relatively brief medical communications between medical practitioners interested in the diagnosis, treatment and management of the plaintiff's reported conditions. As such, they are relevant to these proceedings and they were accordingly admitted into evidence notwithstanding they did not contain reference to having been prepared in accordance with UCPR r 31.23. In the absence of exceptional circumstances being shown to exist, the position may well have been different if those letters were tendered as expert reports that had been prepared in response to requests from the plaintiff's solicitors.
46Dr Guirgis identified the plaintiff's problems as being "further" post-traumatic mechanical derangement of the plaintiff's cervical and lumbar spines. In the context of the described imaging findings related to the 2005 accident, I interpret Dr Guirgis to be here referring to the plaintiff having sustained aggravation type injuries to these areas that were shown on radiology to already be affected by degeneration and previous injury before her 2008 accident.
47It was somewhat telling that the defendant's exhibit bundle comprising Exhibit "D1.2' included an earlier letter from Dr Guirgis dated 21 November 2005. That report identified the plaintiff's 2005 accident to have involved a rear end collision in which the vehicle that struck the plaintiff's vehicle from behind had been travelling at 80kph.
48In that letter Dr Guirgis identified the plaintiff's 2005 accident related complaints as follows:
"... Since then she continued to complain of persistent pain and stiffness in the neck. She described radiation of that pain to involve the right more than the left top of the shoulder blade and right more than left shoulder and down the right arm to the right hand. The right hand, the hand was so weak that sometimes she could not even hold a cup with it. She described pins and needles, numbness and tingling in the fingers of the right hand. She also continued to complain since then of painful stiffness and heaviness in the right shoulder. She also continued to complain of painful stiffness in her lower back and described persistent radiation to involve the right buttock, the back and outer border of the right thigh, the back and outer border of the right calf to the dorsum of the right foot and sometimes to the heel of the right foot. Sometimes the pain down the right leg was so bad causing her to limp with the right leg."
49In that 2005 letter to Dr Soliman, Dr Guirgis made a diagnosis of post-traumatic mechanical derangement of the cervical and lumbar spines with associated radicular symptoms involving both upper limbs and the right leg. He also noted signs of a post-traumatic mechanical derangement of the right shoulder joint. That letter did not identify a prognosis for the symptoms related to those mechanical derangements.
50It seems from this evidence that the plaintiff has understated, albeit inadvertently, the significance and severity of the injuries and the ongoing effects of the 2005 accident.
51In his 2008 letters, Dr Guirgis also identified some related complaints from the plaintiff of radiation of pain and abnormal sensations to both upper limbs and to the left leg. He also identified that the plaintiff was affected by PTSD, a related sleep disturbance, headaches and other related sensory disturbances. Both of the 2008 letters sent by Dr Guirgis to Dr Soliman were in broadly similar terms.
52On 19 January 2008, at the request of the workers' compensation insurer, the plaintiff was examined by Dr Peter Burke, a consultant surgeon. His diagnosis was that the plaintiff had sustained a musculo-ligamentous strain to the cervical spine which he considered was resolving at that time.
53On 12 June 2008, Dr Soliman's notes record that there was a gap in the plaintiff's recollection of the events immediately following the accident and when she became aware she was in a hospital bed.
54On 28 July 2008, Dr Soliman referred the plaintiff to Dr Samir Benjamin, a consultant psychiatrist. The stated purpose of that assessment was for an opinion and for his recommendations for the ongoing management and treatment the plaintiff's PTSD condition.
55Remarkably, other than a two-line referral letter from Dr Soliman to Dr Benjamin, there was no report tendered from any of the plaintiff's several treating general practitioners. Instead the parties tendered several bundles of uninterpreted and voluminous clinical notes produced on subpoena by various treating doctors.
56On 27 August 2008, Dr Guirgis referred the plaintiff to have MRI scans of her brain, cervical and thoracic spines. The brain MRI was reported to be normal. The cervical MRI scan was reported to show posterior bulging of the C4/5 and C5/6 disc spaces with thickening of the endplate margins, but no other abnormalities. The lumbar MRI scan was reported to show desiccation of the L5/S1 disc. No posterior disc protrusion was detected. There was no report correlating these described findings to the plaintiff's reported injuries. There was no evidence indicating whether these reported findings were either caused by, or were contributed to, by the accident on 2 June 2008.
57In this regard, it is relevant to note that the first defendant's tender bundle included a 9 August 2005 MRI report from Dr David Ho. That report indicated a pre-existing C4/5 mild focal disc protrusion of the cervical spine in the presence of a clinical history of C5/6 left radiculopathy.
58On 2 September 2008 the plaintiff was re-assessed by Dr McCarthy. At that time Dr McCarthy thought the plaintiff was developing a chronic pain syndrome. In this regard, Dr McCarthy noted that an appointment had been scheduled for the plaintiff to be seen by Dr Benjamin for psychiatric assessment.
59In September 2008 Dr McCarthy considered that the plaintiff had suffered nothing more than a transient injury to her cervical spine. However, she also noted that this was complicated by psychological factors that were sufficient to interfere with her capacity to manage her daily activities. Dr McCarthy prescribed the medication Lexapro to help the plaintiff with her mood difficulties, to improve her sleep patterns and to also reduce her stress. Dr McCarthy endorsed the need for the plaintiff to have counselling and CBT.
60Dr McCarthy scheduled another review of the plaintiff in a further 2 months. There was no evidence as to whether the plaintiff had in fact attended a further review on that occasion, or as to whether any further report had been issued by Dr McCarthy, following that scheduled consultation.
61On 12 November 2008, at the request of the workers' compensation insurer, the plaintiff was assessed by Dr Leonard Lee, a consultant psychiatrist. He was of the opinion that the plaintiff had no current DSM-IV psychiatric diagnosis, which was in keeping with the opinion of Dr Morse. Dr Lee considered that from a psychiatric perspective, the plaintiff was fit for full time work duties.
62On 15 December 2008, at the request of Dr Soliman, the plaintiff underwent an ultrasound study of her left shoulder, which revealed no abnormalities of the rotator cuff mechanism. As there is no accompanying report from Dr Soliman to provide the clinical context for that referral, or to describe the nature of the symptoms that led to it, the precipitating circumstances of that referral remain opaque to analysis.
63Evidence as to the cause of the plaintiff's problems and treatment during 2009 and 2010 was scant, which was unusual in a case of claims of ongoing physical and psychological problems.
64On 22 May 2009, at the request of the treating general practitioner, the plaintiff was seen by Dr Grant Walker, a consultant neurologist. He considered the plaintiff was "getting a bit 'deconditioned' by her chronic pain" and suggested analgesia and an exercise programme.
65On 19 June 2009, Concord Hospital advised Dr Soliman that the plaintiff had declined treatment and was therefore removed from the waiting list. The specialist was identified as Dr Peter Maitz. No further details of this proposed treatment, or why the plaintiff declined it, are known. In those circumstances I do not consider that this is a relevant failure to mitigate.
66On 19 October 2010, at the request of her solicitors, the plaintiff was assessed by Dr Peter Morse, a consultant psychiatrist. Dr Morse's report of that consultation was dated 30 October 2010. Dr Morse recorded the plaintiff's presenting psychological symptoms as essentially comprising anxiety and tension when driving and whilst travelling as a passenger in motor vehicles. He also noted the history that the plaintiff had at times resorted to shouting at her husband when he drove whilst she was a passenger. Dr Morse also elicited complaints from the plaintiff concerning depression, irritability, sleep disturbance with associated episodic impaired concentration, feelings of guilt concerning her reduced involvement in her son's activities because of the reduced level of her own activities.
67Dr Morse also noted the plaintiff's complaint of unhappiness and sadness at her own physical state. In this regard, he recorded that state as involving problems concerning the plaintiff's neck, left shoulder and low back pain. He also noted the complaint of neck pain radiating to the head, some reduced sitting tolerance, and chest pain related to the left shoulder problems. Dr Morse also recorded that the plaintiff did not complain of any difficulty with her work. However he noted the plaintiff's report of a reduced ability to carry out her housework. He also noted her complaint of reduced social and recreational activities due to her physical state, tiredness and a lack of interest on her part.
68Significantly, Dr Morse was told of the plaintiff's previous injury history which he recorded as comprising post-partum depression in 2003 following the birth of her son in that year. He noted that she had seen Dr Benjamin for that problem. Dr Morse noted the history that after the plaintiff had been taking medication for a period, she had made a full recovery from those symptoms. It is relevant at this point to refer to the earlier involvement of Dr Benjamin in the plaintiff's treatment and assessment.
69Dr Benjamin produced copies of his notes on subpoena spanning the period between 16 April 2003 to 24 September 2008: Exhibit "B". It is noteworthy that Dr Benjamin's records and correspondence do not make any mention of a previous history from the plaintiff concerning the post-partum depression that had been assumed by Dr Morse.
70The tendered records of Dr Benjamin showed that the plaintiff was first referred to him on 27 March 2003, by a general practitioner, Dr Magar, for treatment of what was described in the referral letter as pathological fear, anxiety, depression and insomnia. The questionnaire the plaintiff apparently completed for Dr Benjamin on 16 April 2003 indicated that at that time, she had feelings of sadness, pessimism, lack of enjoyment of life, guilt and disappointment, and other matters of negativity.
71On 16 April 2003, Dr Benjamin wrote to Dr Magar advising him that the plaintiff had a major depressive disorder against a background of significant personality difficulties. Dr Benjamin's reports and notes indicate that in addition to family issues he also treated the plaintiff for auditory hallucinations and self-harm issues in 2003. He prescribed medication and counselling as treatment for these problems. Dr Benjamin saw the plaintiff in a series of 9 consultations between 16 April 2003 and 8 September 2003. The plaintiff was noted to have failed to attend a further appointment on 24 September 2003. There was no explanation from within Dr Benjamin's records for the termination of that treatment. There was no mention of any post-natal depression in that context.
72After a gap of 5 years, during which there were no recorded attendances of the plaintiff, Dr Benjamin's notes then resume with a consultation on 19 August 2008. Dr Benjamin's handwritten notes record a history of the 2005 accident, and an indication that the plaintiff had a month off work, followed by a gradual return to full time employment after 6 months. Dr Benjamin's notes record the plaintiff as having attended a total of 3 consultations with him in the period between 19 August 2008 and 24 September 2008. I shall return to an evaluation of the reports written by Dr Benjamin to Dr Soliman on 19 August and 24 September 2008.
73Dr Benjamin's clinical records identify a history of family problems that affected the plaintiff and which affected her wellbeing. There were references to such matters in the clinical records produced by Dr Soliman. Dr Benjamin also noted that the plaintiff had a history of self-harm. These matters, which were of obvious relevance to a psychiatric assessment of the cause of the plaintiff's complaints, were not explored in evidence and not relevantly considered by the expert psychiatrists in terms of the causation of the plaintiff's claimed psychological problems.
74A complicating feature of any causation analysis concerning the relationship of the plaintiff's psychological problems is the qualified terms of the 2008 opinion of Dr Benjamin's provisional or differential diagnosis:
"Provisional Diagnosis/Differential Diagnosis: Bidaya's presentation is consistent with the diagnosis of Adjustment Disorder with Anxiety and Depressed Mood (mild/moderate severity). There is however, a strong element of exaggeration in her presentation. In addition, there is a significant overlap between her current physical symptoms which occurred following the motor vehicle accident of 2 June 2008 and the physical injured (sic) which she suffered as a result of the first motor vehicle accident of 2005. There is also significant overlap between her current psychological symptoms and her presentation is (sic) 2003 when I saw her. It is not clear if the motor vehicle accident of 2 June 2008 had resulted in marked psychological or physical deterioration in her pre-existing level of functioning."
75This is a matter upon which the plaintiff carried the onus of proof: s 5D of the Civil Liability Act 2002.
76Returning to the psychiatric evaluation of the plaintiff undertaken by Dr Morse, he concluded that the plaintiff was not suffering from any psychiatric condition or emotional disorder, such as a depression or an anxiety state, although he had little doubt the accident had affected the plaintiff's life in a number of areas that he had described.
77Dr Morse did not think the plaintiff required any treatment from the viewpoint of his specialty at the time that he wrote his report. He foreshadowed the possibility that the plaintiff might become depressed and might develop an adjustment disorder if her physical state did not improve. The terms of the report from Dr Morse indicated that these were not firm predictions. It was plain that such predictions clearly involved a good deal of speculation for which evidence was necessary to support any findings as the existing material was insufficient to base reasoned inferences.
78There was no updated report from Dr Morse concerning the condition of the plaintiff, either in 2011 or 2012. Nor was there any evidence as to whether the views Dr Morse had expressed in 2010 as to the plaintiff's condition, had changed in any way since he had furnished his report dated 30 October 2010. This is a matter upon which the plaintiff carries the onus of proof.
79As the following summary shows, no evidence has been tendered to show that the plaintiff has gone on to develop depression or an adjustment disorder as was indicated by Dr Morse as a potential possibility.
80On 1 December 2010, at the request of her solicitor, the plaintiff was assessed by Dr P Endrey-Walder, a consultant general and trauma surgeon. In his report of that consultation, Dr Endrey-Walder reviewed the plaintiff's history and the radiological findings he was given, and provided his opinion to the effect that the plaintiff's neck and back injuries from the 2008 accident were of a soft tissue nature. He also stated that there was no doubt that the plaintiff's injuries were superimposed upon a degree of residual pain and restriction of movement of the neck and lower back as a consequence of the injuries she sustained in the 2005 accident. He assessed the plaintiff's left shoulder problems as being a consequence of the neck injury due to an associated referred pain from the trapezius muscle.
81On 23 August 2011, at the request of the solicitor for the Nominal Defendant, the plaintiff was assessed by Dr RWD Middleton, a consultant orthopaedic surgeon. After reviewing the plaintiff's neck, shoulder and back symptoms, Dr Middleton concluded that the plaintiff's marked limitation of movements in the cervical and lumbar spines, and in both shoulders, were not credible complaints in the absence of major injury. He thought there was no impairment in the plaintiff's ability to work. He also concluded there was no evidence of an impairment that required personal or domestic care and assistance.
82On 6 September 2011, at the request of the solicitors for the Nominal Defendant, the plaintiff was assessed by Dr Inglis Howe Synott, a consultant psychiatrist. Dr Synott concluded that the plaintiff did not have a psychiatric condition. From a psychiatric perspective, he considered that the plaintiff had no restrictions on her ability to work full time or to carry out her domestic responsibilities without assistance.
83On 22 September 2011, Dr Endrey-Walder reassessed the plaintiff and provided a further report on her condition. He noted that the plaintiff was now seeing Dr Akram Maussad as her current general practitioner and that he had prescribed Mersyndol Forte for her pain, Mobic for pain, and Endep, which was noted to be an anti-depressant. Dr Endrey-Walder did not say whether Endep had been prescribed for depression. He noted that the plaintiff's symptoms of neck, left shoulder and low back problems had continued since he had last assessed her. He also noted that she was particularly distressed at the deterioration in her condition of her lower back in the previous couple of months. Without expert psychiatric opinion to comment on this evidence, this latter opinion is not a sufficient basis to infer the plaintiff had a currently diagnosable psychiatric condition: Strinic v Singh [2009] NSWCA 15.
84Dr Endrey-Walder went on to express the provisional opinion that the plaintiff was suffering from facet joint damage to her cervical and lumbar spines. He reiterated a request for a bone scan to be carried out in order to confirm his provisional diagnosis. He also recommended an MRI scan of the plaintiff's left shoulder.
85Dr Endrey-Walder also expressed his impression that if the plaintiff's work hours could be reduced to say 5 hours per day for 5 days per week, her working life would be prolonged, as he thought that the plaintiff seemed to be "at the end of her tether". He did not explain the applicable time span for that recommendation to apply.
86Dr Endrey-Walder supported a claim for the plaintiff to receive domestic assistance as a result of the 2008 accident. In that regard, he estimated the plaintiff's need for such assistance to be for at least one hour per day.
87On 11 November 2011, Dr Endrey-Walder reviewed a report of an MRI scan taken of the plaintiff's left shoulder. I infer this to have been the report of Dr Connolly dated 24 October 2011, which diagnosed the plaintiff to have supraspinatus tendonitis and mild axillary pouch synovitis. Dr Endrey-Walder interpreted the MRI scan to show supraspinatus tendonitis without a tear. He noted the possibility that the plaintiff may have an impingement syndrome of her left shoulder but he also stated that the plaintiff's gross restriction of shoulder movements that she had displayed at his last examination of her on 22 September 2011 could not be accounted for, to the extent of even one-tenth by those findings.
88That last cited statement suggested other factors were influencing the plaintiff's presentation. As it was not directly suggested to the plaintiff that she was fabricating her symptoms, the significant remaining possibility to be considered is some kind of psychological explanation. Unfortunately, the state of the psychiatric evidence does not enable an inferred or concluded view to be formed on that matter as this involves a medical opinion for which evidence is required: Strinic v Singh [2009] NSWCA 15.
89On 13 December 2011, at the request of the solicitor for the first defendant, Dr Bruce Trevitt, an orthopaedic surgeon, provided those solicitors with a commentary on the plaintiff's condition. That commentary was said to be in reference to an earlier report he had provided to those solicitors on 3 November 2011.
90Since Dr Trevitt's 3 November 2011 report was not tendered in evidence, I have discounted the commentary in his 13 December 2011 report that expressed criticism of the plaintiff because the full context is not apparent due to the absence of that first report. A similar comment applies to the subsequent letter from Dr Trevitt dated 14 December 2011.
91The clinical notes of Dr Maussad, the plaintiff's new general practitioner, were produced on subpoena.
92Those records show a total of 9 consultations with the plaintiff between 28 June 2011 and 24 November 2011. The presenting problems at those consultations ranged from left shoulder pain (at the initial consultation), to chronic neck and back pain (at the third consultation), and dizziness and nausea (at the fourth consultation). Ultrasound and MRI investigations were variously noted to have revealed subacromial /sub-deltiod bursitis with impingement in the left shoulder, suprapinatus tendinosis, adhesive capsulitis and mild axilliary puch synovitis. This condition was treated with injections. The cause of the supraspinatus tendonitis must be doubtful so far as the 2008 accident is concerned because of the earlier diagnosis of that condition in 2003.
