Issued under Division 7.5 of the Motor Accident Injuries Act 2017
The Review Panel confirms the certificate of Medical Assessor Surabhi Verma dated
"4 Meaning of 'threshold injury', section 1.6(4) of the Act
(2) Each of the following injuries is included as a threshold injury for the purposes of the Act -
Note - See section 1.6 (5) of the Act in relation to the making of Motor Accident Guidelines for or with respect to the assessment of whether an injury is a threshold injury.
(3) In this clause acute stress disorder and adjustment disorder have the same meanings as in the document entitled Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association in May 2013."
"5.3 The assessment will determine whether the injury related to the claim is a soft tissue injury or a threshold psychological or psychiatric injury caused by the motor accident.
5.4 Insurers must not require injured persons to undergo diagnostic imaging for the purpose of the insurer determining whether the injury related to the claim is a threshold injury. Diagnostic imaging is not considered necessary to assess threshold injury.
5.5 A diagnosis for the purpose of a threshold injury decision must be based on a clinical assessment by a medical practitioner or other suitably qualified person independent from the insurer.
5.6 The assessment of whether an injury caused by the accident is a threshold injury for the purposes of the Act should be based on the evidence available and include all relevant findings derived from:
(a) a comprehensive accurate history, including pre-accident history and pre-existing conditions
(b) a review of all relevant records available at the assessment
(c) a comprehensive description of the injured person's current symptoms
(d) a careful and thorough physical and/or psychological examination
(e) diagnostic tests available at the assessment. Imaging findings that are used to support the assessment should correspond with symptoms and findings on examination."
"5.10 In assessing whether an injury is a threshold psychological or psychiatric injury, an assessment of whether a psychiatric illness is present is essential.
5.11 The assessment of whether a psychiatric illness is present must be made using the Diagnostic & Statistical Manual of Mental Disorders, Fifth Edition, Text Revision (DSM-5-TR), published by the American Psychiatric Association.
5.12 Where the symptoms associated with the injured person's psychological or psychiatric injury do not meet the assessment criteria for a recognised psychiatric illness, with the exception of acute stress disorder and adjustment disorder, the injury will be considered a threshold injury."
Certificate of Determination - Internal Review
(a) criterion A: accident where he felt his life was in danger;
(b) criterion B: recurrent intrusive dreams, flashbacks, dreams of the accident and psychological reactivity;
(c) criterion C: persistent avoidance of driving, avoiding accident site, inability to recall certain aspects of the accident, decreased interest in activities, restricted range of affect;
(d) criterion D: insomnia, irritability, difficulty with concentration, startled;
(e) criterion E: lasting for more than a month, and
(f) criterion F: causing significant distress.
"Mr Teghlian reported the following symptoms and behaviours; feeling depressed and/or anxious at least 3 days per week, difficulty coping since MVA in May 2023, very poor sleep regime including initial insomnia and frequent waking, frequent nightmares at least one day per week pertaining to MVA, loss of motivation/morale impacting his employment as well as domestic duties and hobbies, socially withdrawn/decreased interest in most things, mind racing, difficulty relaxing, decreased cognitive functioning (attention, concentration) impacting his day to day life including work, irritability and frustration with some anger outbursts and an overall feeling of worry about the future."
Certificate of Capacity / Certificate of Fitness
(a) Criterion A. Mr Teghlian was involved in a motor in which he was exposed to threatened serious injury. In the clinical judgement of the psychiatrist members of the Panel, this criterion is met. While the accident was low speed, it involved a collision to the passenger side of the vehicle which broke the windscreen above Mr Teghlian's head and caused him to be showered in glass. The corner of the truck was directly in front of Mr Teghlian's face, and he could have suffered serious injuries had his wife not taken evasive action. Police and ambulance attended.
(b) Criterion B. Mr Teghlian described recurrent distressing dreams in which the content was related to the motor accident. This criterion is met.
(c) Criterion C. Mr Teghlian did not avoid memories, thoughts or feelings about the motor accident or external reminders about the motor accident. This criterion is not met.
(d) Criterion D. Mr Teghlian did not describe negative alterations in cognitions and mood associated with the accident. This criterion is not met
(e) Criterion E. Mr Teghlian did describe alterations in arousal and reactivity associated with the motor accident consisting of problems with concentration and sleep disturbance. This criterion is met.
(f) Criterion F. Duration has been greater than one month. This criterion is met.
(g) Criterion G. Significant distress or impairment in social and occupational functioning. This criterion is met.
(h) Criterion H. The condition is not attributable to a substance or another medical condition. This criterion is met.
(a) Criterion A. He developed emotional and behavioural symptoms within 3 months of the motor accident.
(b) Criterion B. The symptoms he described are clinically significant. His distress is out of proportion to the severity of the stressor and it resulted in some impairment in social and occupational functioning.
(c) Criterion C. Criteria for another mental disorder were not met and the condition is not an exacerbation of a pre-existing disorder.
(d) Criterion D. The symptoms do not represent normal bereavement.
(e) Criterion E. The condition is present in persistent form because it has not resolved within 6 months.
6.6 Causation is defined in the Glossary at page 316 of the AMA4 Guides as follows:
'Causation means that a physical, chemical or biologic factor contributed to the occurrence of a medical condition. To decide that a factor alleged to have caused or contributed to the occurrence or worsening of a medical condition has, in fact, done so, it is necessary to verify both of the following:
This, therefore, involves a medical decision and a non-medical informed judgement.
6.7 There is no simple common test of causation that is applicable to all cases, but the accepted approach involves determining whether the injury (and the associated impairment) was caused or materially contributed to by the motor accident. The motor accident does not have to be a sole cause as long as it is a contributing cause, which is more than negligible. Considering the question 'Would this injury (or impairment) have occurred if not for the accident?' may be useful in some cases, although this is not a definitive test and may be inapplicable in circumstances where there are multiple contributing causes."
"One may accept that a review panel is engaged in a process of dispute resolution by expert assessment of medical issues arising under the Act. However, the questions arise in a legal context and it is incumbent upon the panel, medical practitioners they may be, to correctly apply the law including the law of causation in the exercise of their powers. This includes the provisions of Division 3 of Part 1A of the Civil Liability Act 2002 (NSW), ss5D and 5E: see s 3B(2)(a) of that Act. Although it may be expected that questions about the appropriate scope of liability will arise but rarely."
"An inference of causation for purposes of the tort of negligence may well be drawn when a scientist, including an epidemiologist, would not draw such an inference."
