WHETHER THE DEGREE OF PERMANENT IMPAIRMENT OF THE INJURED PERSON AS A RESULT OF THE INJURY CAUSED BY THE MOTOR ACCIDENT IS GREATER THAN 10%

The assessment made by the review panel under s 63(4) of the Motor Accidents Compensation Act, 1999 is as follows:

1. The Review Panel revokes the certificate of Medical Assessor Mason dated

14 April 2023 and issues a new certificate that the following injury caused by the motor accident give rise to a whole person impairment which is not greater than 10%:

(a) Major depressive disorder - of moderate severity.

1. [BPO] (the claimant) was injured in a motor accident on 25 October 2016. The claim form records that the claimant was riding in her lane when the insured vehicle "cut me off" and caused the accident.[1]
2. Insurance Australia Ltd trading as NRMA (the insurer) is liable to pay [BPO] any damages under the Motor Accidents Compensation Act 1999 (the MAC Act).
3. The present dispute between the parties is whether the degree of permanent impairment as a result of the injury caused by the motor accident is greater than 10%. This constitutes a medical dispute within the meaning of the MAC Act.[2]
4. Section 44(1)(c) of the MAC Act provides that the State Insurance Regulatory Authority may issue guidelines with respect to the assessment of the degree of permanent impairment of an injured person as a result of an injury caused by a motor accident.
5. The Motor Accident Permanent Impairment Guidelines (the Guidelines) were issued pursuant to s 44(1)(c) for the assessment of permanent impairment. The Guidelines adopt the fourth edition of the American Medical Association's Guides to the Evaluation of Permanent Impairment (AMA 4). Where there is any difference between AMA 4 and the Guidelines, the Guidelines are definitive.[3]
6. The present application is a review of a medical assessment pursuant to s 63 of the MAC Act. The medical assessment the subject of this review was conducted by Medical Assessor Mason on 14 April 2023 (the medical assessment). Medical Assessor Mason assessed the permanent impairment caused by the motor accident at 19%.
7. The application for referral of a medical assessment to a Review Panel (the Panel) was made by the insurer within 28 days after the parties were issued with the original certificate for the medical assessment for which the review is sought.[4]
8. The delegate of the President referred the medical assessment to the Panel as they were satisfied that there was reasonable cause to suspect that the medical assessment was incorrect in a material respect having regard to the particulars set out in the application.[5]
9. Pursuant to s 63(3) of the MAC Act and Schedule 1, cl 14F (2) of the Personal Injury Commission Act 2020 (the PIC Act), the Panel consists of two Medical Assessors and a Member of the Motor Accidents Division of the Personal Injury Commission (Commission).

1. This review is from the Medical Assessment Certificate issued by Medical Assessor Mason when it was determined that the motor accident caused a somatic symptom disorder (pain) and an Adjustment Disorder with Mixed Anxiety and Depressed which was severe and chronic and assessed the claimant at 19% permanent impairment.
2. The following summary of the reasons provided by Medical Assessor Mason are largely an adoption of the reasons provided by McNaughton J in Zilic v QBE Insurance (Australia) Ltd.[6]
3. The Medical Assessor noted that a pre-existing psychological history associated with previous relationships between 2010 and 2015 with treatment consisting of a low dose of antidepressant medication. Prior to the motor accident the claimant had met her husband and had been living together in a happy relationship for approximately two months. The claimant was "doing well with her job in Westpac", was performing well in a Master of Law degree at Sydney University and engaged in a business venture. The Medical Assessor opined that the claimant had prior psychological difficulties consisting of adjustment disorders with mixed anxiety and depressed mood which arose because of disappointments in romantic relationships and an experience of harassment by an unwanted suitor. The Medical Assessor found that while it was most likely these have largely settled due to her relaxed satisfactory relationship with her future husband, he apportioned for a pre-existing condition.
4. The Medical Assessor noted the serious degloving injuries with the onset of chronic pain and referral to Northern Beaches Psychiatric Unit in 2019.
5. In respect of his diagnosis of the psychological conditions, the Medical Assessor found that the claimant developed a somatic symptom disorder (pain) and an Adjustment Disorder with Mixed Anxiety and Depressed which was severe and chronic. The Medical Assessor accordingly agreed with the conclusion reached by Dr Vickery as to the somatic symptom disorder and also made a further diagnosis consistent with the conclusions reached by Dr Anthony Dinnen, treating psychologist Ms Gorrell, the treating pain management psychiatrist Dr Holton and the psychiatric consultant at the Northern Beaches Hospital. The Medical Assessor provided the following conclusion on diagnosis.

"The claimant has developed a Somatic Symptom Disorder (pain) as a consequence of the subject motor accident. This is the case whether she suffers from CRPS or simply from chronic pain. She was initially hopeful this could be cured and her psychiatric condition deteriorated greatly when this proved not to be the case. This in turn created a great deal of disruption in her life. She has been unable to continue with a valued job and university study which would have most likely led to career advancement. It has created difficulties for her in all of her relationships. It has also created difficulties for her in her ability to function as a mother. In my opinion her chronic and severe Adjustment Disorder with Mixed Anxiety and Depressed Mood has arisen secondarily to the ongoing Somatic Symptom Disorder (pain)."

1. The Medical Assessor assessed psychological impairment at 19%. There are references in the Psychiatric Impairment Rating Scale's (PIRS) categories to aspects of pain affecting the claimant's functioning such as not being able to shower partly because it is painful, being physically limited in her ability to participate in social and recreational activities and only tried to work for one day and was defeated by pain.

PREVIOUS REVIEW PANEL AND SUPREME COURT PROCEEDINGS

1. A previous Review Panel concluded that the motor accident caused a primary diagnosis of persistent somatic symptom disorder with predominant pain, stating that this was the most appropriate fit for the claimant's symptoms.
2. In Zilic the Court set aside the certificate issued by the Review Panel and ordered that her medical assessment be remitted to a differently constituted Panel.
3. We do not intend to summarise the reasons of the previous Review Panel as the previous certificate has been set aside. The Court found jurisdictional error and/or error on the face of the record which we summarise as follows.
4. First, the Review Panel erroneously limited itself to determining only a primary diagnosis and did not consider whether the motor accident resulted in a secondary diagnosis which could be assessed by way of permanent impairment. The previous Review Panel did not consider, by reference to Medical Assessor Mason's findings, that the motor accident also caused an adjustment disorder with mixed anxiety and depressed mood which was chronic and severe. The previous Review Panel made no reference to Dr Dinnen's diagnosis and why it was not appropriate to have regard to a consequential or secondary diagnosis.[7]
5. Secondly, there was a complete absence of any analysis why the persistent somatoform disorder with predominant pain in turn contributed to the occurrence of another recognised psychiatric condition.[8]
6. Thirdly, the Review Panel erred in failing to provide reasons why it disagreed with the opinion of Medical Assessor Mason and Dr Dineen that the claimant had a psychiatric condition which had arisen secondarily to the primary psychiatric condition.[9]

1. Part 5 of the PIC Act enables the Commission to make rules with respect to the practice and procedure before the Commission including proceedings before a panel reviewing a decision of a Merit Reviewer or a Medical Assessor.[10]
2. Rules 127 to 130 of the Personal Injury Commission Rules 2021 (the PIC Rules) are made pursuant to Part 5 of the PIC Act. A Review Panel determines how it conducts and determines the proceedings and may determine the proceedings solely based on the written application.[11]
3. The review is by way of new assessment of all matters with which the medical assessment is concerned.[12]

1. The provisions of the Civil Liability Act 2002 (the CL Act) apply to the Motor Accident Injuries Act 2017 in determining issues of causation. Particularly ss 5D and 5E of the CL Act.[13] In Raina v CIC Allianz Insurance Ltd[14] Campbell J stated:

"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."

"There is no simple common test of causation that is applicable in 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 the sole cause as long as it is a contributing cause, which is more than negligible."

Insurer's submissions dated 6 April 2021[15]

1. The insurer noted pre-accident medical records which showed:
   • - diagnosed with depression on 5 February 2013 placed on Citalopram,
   • - seeing a psychologist in May 2013 and medication changed to Lexapro;
   • - in August 2014 it was noted the applicant was an abusive relationship, and
   • - on 20 February 2015 was seen by Dr Lee for anxiety.
2. The insurer referred to the opinion of Dr Vickery dated 21 October 2020 who diagnosed a chronic pain disorder and considered that occurred in the context of the claimant's multiple personal stresses and pre-existing vulnerabilities.
3. The insurer referred to the opinion of Dr Maxwell in October 2020 who diagnosed the claimant with a hypochondriacal personality with no current relationship between the subject accident and the alleged disabilities apart from the foot discomfort associated with left ankle restriction on abnormality for the superficial peroneal nerve.
4. The insurer referred to the Medical Assessment Certificate issued by Medical Assessor Cameron who noted the claimant did not meet the diagnostic criteria for complex regional pain syndrome (CRPS) and found that the current presentation was more consistent with chronic pain syndrome. The Medical Assessor noted inconsistency of movement in multiple body parts in the spine from a physical's perspective the claimant was capable of working.
5. The insurer submitted that the claimant had pre-existing injuries and disabilities including pre-existing depression which must be considered when assessing permanent impairment.

Insurer's submissions dated 20 May 2022[16]

1. These submissions sought leave to review the medical assessment certificate.
2. The insurer referred to clause 1.125 [sic] of the guidelines which provide that the PIRS must not be used to measure impairment due to somatoform disorders or pain. It submitted that the Medical Assessor reason the claimant's chronic and severe adjustment disorder and mixed anxiety and depressed mood was due to the somatoform disorder and could not be assessed.
3. The insurer submitted that the Medical Assessor was in breach of clause 1.125 by assessing various categories in relation to the claimant pain. The insurer noted that the assessment for self-care and personal hygiene, social and recreational activities and concentration persistence and pace where references were made to pain in making the assessment of the particular class.
4. The insurer submitted that the history concerning the applicant's pre-existing condition was inaccurate as there was no reference to the upper claimant being prescribed Celepram tablets 10mg one daily on 16 June 2016 that is only 18 weeks prior to the accident. This evidence contradicted the history recorded by the Medical Assessor that the use of antidepressant medication ceased in early to mid-2015.

Claimant's submissions dated 16 June 2022[17]

1. These submissions were filed opposing leave to review the medical assessment.
2. The claimant submitted that the insurer's argument that the adjustment disorder with mixed anxiety and depressed mood arose secondarily to an ongoing somatic symptom disorder was not assessable was flawed. The claimant refers to clause 1.213 of the Guidelines.
3. The claimant accepted the somatoform pain disorder cannot be used for the calculation of permanent impairment but noted the findings of the Medical Assessor of an independent psychiatric condition.
4. The claimant submitted that the assessments of various PIRS categories were not conducted "purely based on pain"[18] in reference to findings which were partly based on pain and partly due to anxiety and depression.
5. In relation to the antidepressant medication prescribed 18 weeks prior to the motor accident, the claimant submitted that there was no suggestion that there was objective evidence of any pre-existing symptomatic permanent impairment at the time of the accident. The claimant otherwise refers to other facts which suggested no loss of functional impairment such as working at Westpac, happiness in a new relationship, her performance in the Master of Laws degree and the ability to engage in secondary employment in the running of a café with her partner.

The claimant said that she was treated with psychological therapy, dialectical behavioural therapy (DBT) and antidepressant pharmacotherapy. She was not referred for electroconvulsive therapy or repetitive transcranial stimulation as an inpatient. The patient said she was discharged to the care of her psychiatrist Dr Holton and psychologist and had not return to psychiatric hospital since 2019. At the time of this re-examination the claimant said she was continuing to be prescribed citalopram 20mg daily with Endep (amitriptyline) 25mg at night. She continued to attend her psychiatrist and psychologist once every month.
3. The Panel notes that the treating psychiatrist provided further diagnostic advice that the exclusion of major depressive disorder could not be made without further longitudinal clinical observation. Whilst the suggested diagnosis was adjustment disorder with mixed anxiety and depressed mood, the treating psychiatric also included as a possible future diagnosis of major depressive disorder should the claimant's condition fail to recover or deteriorate clinically. The making of this diagnosis was in 2019 and at the time of this re-examination in 2025, the presence of a more prominent depressive disorder was clinically apparent to the Medical Assessors.

1. The claimant's current symptoms at the time of this re-examination were assessed in the paragraphs below:

The claimant had the following symptoms of major depressive disorder as follows:

• depressed mood most of the day, nearly every day, as evidenced by the claimant's feelings of hopelessness and worthlessness.
• Markedly diminished interest with inability to experience pleasure in almost all activities for most of the day, nearly every day as evidenced by the loss of her career, loss of her interest in her self-care and personal hygiene and loss of interest intimacy with her husband
• Insomnia nearly every night with initial and middle insomnia where she would wake from sleep and not return to sleep.
• Diminished ability to concentrate with increased indecisiveness when attempting to make decisions or attempt to progress any complex task.
• Fatigue with loss of energy nearly every day.
• Recurrent suicidal thoughts without intent to self-harm at the time of the re-examination.
• Depressive ruminations about been trapped in a never-ending medical condition with inappropriate feelings of excessive shame and guilt, "I wanted to contribute more than just a stay home mother".
• Loss of her self-esteem and identity.

1. The claimant reported that she still experienced pain every day. She said that the severity of her pain was exacerbated by touch. She said that heat whether cold or hot also exacerbated her pain. She reported that none of the medications, treatment, physiotherapy or psychological treatments had results in resolution of her pain.
2. The claimant explained that she had spoken to her pain team and her GP about her pain experience. she said she had asked about "somatic pain". She said she was told she by her pain treatment team that she "did not have somatic pain." She said she was diagnosed with "CRPS". The Medical Assessors explained that the diagnosis of "CPRS" was a physical physician's diagnosis and not part of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5-TR).
3. The Medical Assessors explained that the assessment by the previous Review Panel of "Somatic symptom disorder - with predominant pain" had been set aside and the reconstituted Panel was starting a new with this re-examination.
4. The claimant said she wanted to show her affected foot and limb during the assessment. The Medical Assessors explained that they would not be able to fully examine her affected foot as specific tests such as light touch and measurement of muscle bulk for asymmetrical muscle wasting could not be performed in the MS Teams assessment format. The claimant was asked to directly describe her pain as she was experiencing it at the time of this re-examination.
5. The claimant said her left foot was very painful and, in the lead, up to this re-examination had increased in pain. She said the foot and lower leg around the ankle had become swollen. She said she had ongoing trouble with light touch and her husband was required to massage her foot and affected areas where pain was most severe.
6. The claimant suffered from a severe iatrogenic side-effect of the use of ketamine for pain treatment. She developed a drug induced hepatitis with elevation of liver enzymes due to the use of ketamine. This severe drug side-effect is a known side-effect for the use of ketamine regardless of for which indication it is prescribed. Withdrawal of ketamine resulted in her liver function returning to normal.

1. The claimant presented as an agitated sullen and depressed woman who looked older than her stated age. She did stand on two occasions at the 45-minute and 90-minute mark of this re-examination. She reported pain on each time she stood. She stretched and then settled again sitting.
2. The claimant reported loss of joy and pleasure in her life. She said she was not interested in intimacy with her husband. She said she was not motivated to manage her self-care and personal hygiene. She said she relied on support of her family to help her care for her children. Her energy was low. She had a depressed mood most days for most of the day.
3. The claimant reported that her café business was placed in liquidation as she could not manage the financial aspects of the business. She said she had intrusive and distressing suicidal thoughts. She said her relationship with her husband was strained and her relationship with her children was not as enjoyable as she had hoped.
4. The claimant said she had ongoing pain which impaired her capacity to shower and cook complex meals. She said that the pain was present every time she took a shower. She said that both hot and cold water increased the severity of her pain. The claimant said that because of the pain she relied more on her husband to assist with the hygiene of her daughters. He would supervise and assist with showers daily for the children.
5. The claimant said she was unable to return to work as she had experienced reduced capacity to travel due to her pain in her left foot and other sites of her body. She said she was no longer able to life her 19-month-old toddler as she was now too heavy.
6. The claimant said she had lost motivation and interest in her hobbies and social sport. She said she was not interested in her career or studies. She had not done any short courses online as she lacked interest and no longer enjoyed learning.

1. Using DSM-5-TR criteria the claimant's DSM-5-TR F32.1 Major depressive disorder - of moderate severity is defined as:

The following symptoms have been present during the same two-week period and represent a change from previous functioning with the claimant experiencing a depressed mood as well as the following:

• Depressed mood most of the day, nearly every day, as evidenced by the claimant's feelings of hopelessness and worthlessness.
• Markedly diminished interest with inability to experience pleasure in almost all activities for most of the day, nearly every day as evidenced by the loss of her career, loss of her interest in her self-care and personal hygiene and loss of interest sharing recreational and social activities with her parents or foster-sister
• Insomnia nearly every night with initial and middle insomnia where she would wake from sleep and not return to sleep.
• Diminished ability to concentrate with increased indecisiveness when attempting to make decisions.
• Fatigue with loss of energy nearly every day.

Other symptoms of major depressive disorder include:

• Recurrent suicidal thoughts without intent to self-harm at the time of the re-examination.
• Depressive ruminations about been trapped in a never-ending medical condition with inappropriate feelings of excessive shame and guilt, "I wanted to contribute more than just a stay home mother".
• Loss of her self-esteem and identity where she said,

Whilst these other symptoms of major depressive disorder were present at the er-examination they are not part of the minimum necessary symptoms for diagnosing major depressive disorder.

The symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.

This criterion is met by the claimant not been able to return to work due to her increased disorganised behaviour caused by her major depressive disorder symptoms.

The episode is not attributable to the physiological effects of a substance or to another medical condition.

This criterion is met as the onset of unremitted symptoms of pain caused her to become depressed in her mood due to the trauma and consequences of the injury sustained in the motor accident.

The occurrence of the major depressive episode is not better explained by schizoaffective disorder, schizophrenia, schizophreniform disorder, delusional disorder, or other specified and unspecified schizophrenia spectrum and other psychotic disorders.

This criterion is met as the claimant does not have a history of any of these conditions.

There has never been a manic episode or a hypomanic episode.

This criterion is met as the claimant does not have a history of any of these conditions.

For the above reasons the claimant meets all the criteria required to diagnose DSM-5-TR F32.1 Major depressive disorder - of moderate severity.

1. The Medical Assessors note that using DSM-5-TR F45.1 criteria for Somatic Symptom Disorder - the symptom of depressed mood is not included in this diagnosis. At the time of the re-examination that claimant did not spontaneously report anxiety a common symptom which is part of the diagnosis of Somatic Symptom Disorder.
2. The Medical Assessors note that the presence or absence of CRPS does not exclude the clinical presence of pain from other causes.
3. At the time of this assessment the claimant did suffer from pain which significantly affects the claimant's day to day functioning. Whilst the diagnosis of DSM-5-TR F45.1 criteria for Somatic Symptom Disorder with predominant pain is excluded for the above reasons, the Medical Assessors note guidelines:

(a) 6.214 impairment due to physical injury is assessed using different criteria outlined in other parts of these Guidelines, and

(b) 6.215 the PIRS must not be used to measure impairment due to somatoform disorders or pain.

The Medical Assessors note that the classification of the pain outside of DSM-5-TR F45.1 criteria for Somatic Symptom Disorder with predominant pain is outside the scope of clinical psychiatric practice as evidenced by the need for a multidisciplinary team at the Pain Clinic that the claimant utilised.

1. In brief, pain from any cause is excluded from assessment under the PIRS' categories.
2. The Medical Assessors note that the history provided by the claimant and the nature of her psychological injury is more severe than defined using DSM-5-TR Adjustment disorders as defined starting at page 319 of the manual. At the time of this re-examination the diagnosis of adjustment disorder of any type was excluded where other clinicians have recognised major depressive disorder as well as the treating psychiatrist's advice that major depressive disorder was likely to present should the claimant have longitudinal clinical observation as has occurred up to the time of this re-examination.

1. The claimant was independent in her lifestyle, capacity to work, capacity to form new relationships after ceasing prior relationships as well as her capacity to study, work fulltime and run a small business, before the motor accident.
2. The claimant was in a significant motor accident. The motorcycle was on top of her as she slid on the road and suffered the onset of her injuries. She suffered a degloving injury of her left foot's skin. She required skin grafting. She was in pain at the time of the motor accident and has remained in pain since. Various diagnoses have been offered as to the cause of her pain.
3. The claimant suffered from a significant physical injury to the nerve distribution of her left foot. The claimant had many unsuccessful trials of physical, psychological and pharmacological treatment that failed to place her physical injury symptoms including pain into full remission. The ongoing presence of pain is evidence from the documents provided as well as the claimant's self-report at the time of the re-examination.
4. The claimant had significant clinical side-effects from the use of ketamine for pain relief. The side-effect remitted with return of her liver function to normal on stopping ketamine.
5. The nature of the motor accident and subsequent compilations of treatment necessary could, in the Medical Assessors opinion caused the psychological injury major depressive disorder as defined by DSM-5-TR.
6. The findings on re-examination, forwarded documents history of hospitalisation after a suicide attempt, as well as failed treatments for her physical injuries including pain for all causes did cause the claimant to suffer from a major depressive disorder whilst also suffering from pain.

The claimant reported that she had less energy and less interested in her selfcare and personal hygiene. She said she that she was able to shower independently. She her appetite was reduced, and she would skip meals. She was less interested in cooking. Her mother would bring food the family. The Medical Assessors assessed a Class 2, mild impairment for the assessable psychological injury caused by the motor accident.

The claimant said that she avoided showering most days as she would experience pain when the shower water hit her foot. She said she had pain whether the water was hot or cold. She said she did less cleaning of her home due to pain. She said she would prepare less meals due to pain. She reported that her husband would do most of the groceries. She said her self-care and personal hygiene was significantly impaired by her pain. The loss of function due to pain was not included in the assessment of impairment for this table of functioning.

The claimant reported that she was too depressed to interest in socialising with her past friendship circle. She said she had no pleasurable recreational activities or experiences since the onset of this injury. She reported that she was not interested in playing with her young children. She said she did participate in a mothers' playgroup. She said she did not participate in her children's childcare centre events or activities. The Medical Assessors assessed a Class 3, moderate impairment for the assessable psychological injury caused by the motor accident.

The claimant reported that her pain affected her motivation to plan social events or activities for her, her family and her involvement in her extended family celebration or events. She said she was unable to be pain free sufficiently to participate in any social or recreational activities within her extended family. The loss of function due to pain was not included in the assessment of impairment for this table of functioning.

The claimant was able to leave her home and use her car to travel short distances within her local and familiar areas. She was able to attend her pharmacy to collect essential medication. The Medical Assessors assessed a Class 2, mild impairment for the assessable psychological injury caused by the motor accident.

The claimant said that she used a heated seat and a TENS (transcutaneous electric stimulator) to manage her pain whilst driving. She said her pain whilst using these pain management strategies enabled her to manage her pain for short periods. She said she had never ridden a motorcycle again as she had lost her life due to pain caused by the physical injury sustained in the motor accident. The loss of function due to pain was not included in the assessment of impairment for this table of functioning.

The claimant said she was less intimate with her partner and that they shared a "platonic relationship". She said she was grateful for her husband's extensive work and long hours of work at the café as well as his interest and care of the daughters. She said she was not expecting any separation, divorce and domestic violence between her and her husband. The claimant said she felt a strong bond to her daughters. She said that there was tension within her relationship within her family due to the motor accident. The Medical Assessors assessed a Class 2, mild impairment for the assessable psychological injury caused by the motor accident.

The claimant said that her pain had not prevented her from forming a strong maternal bond with her daughters. She said her pain had not prevented her from supervising their needs and care provided by her mother, husband and other members of the family.

The loss of function due to pain was not included in the assessment of impairment for this table of functioning.

The claimant was able to participate throughout the re-examination which lasted about 100 minutes. She was able to provide information as to her injury and other factors which were similar to the reports provided by other assessors. The claimant said she had not participated in any new learning since the motor accident. She said she had lost interest in study. She had no other hobbies such as knitting, craft or art before the motor accident. She said she had little need to read or perform complex tasks such as cooking as this would be organised by her husband. She said since the liquation and selling of her small business to her husband she did not need to perform any of her prior complex tasks. The claimant did require brief break in the re-examination due to pain and her depressive symptoms becoming prominent when she was talking about her loss of completing her Master of Law Studies. It was the view of the panel that if not for the pain at or about the 45 minute mark of this re-examination then the claimant was able to manage complex tasks and stay on task throughout this re-examination without prompting. The claimant could focus on the questions and provided consistent and reliable responses without prompting. She was able to concentrate for more than 30 minutes during the early phase of this re-examination without any observed impairment in her concentration, persistence and pace. The Medical Assessors assessed a Class 2, mild impairment for the assessable psychological injury caused by the motor accident.

The assessment of the claimant's concentration persistence and pace assessable to the psychological injury at the time of this assessment was assessed with consideration of forwarded documents regarding the contribution of the psychological injury to the assessable impairment of concentration, persistence and pace from the contribution of pain to the claimant's difficulties with respect to concentration, persistence and pace.

The Medical Assessors noted: At the time of the claimant was admitted to Northern Beaches hospital when her psychological injury requiring acute inpatient psychiatric treatment her treating psychiatrist Dr Peter Jones on 28/05/2019 for his clinical assessment of "... attention/concentrating, planning..." wrote that the claimant's functioning was "Grossly intact..." i

During the same admission to the Northern Beaches the claimant's treating psychologist Mackertich on 05/06/2019 at the time of clinical assessment documented the following: "Sensorium & Cognition: Px (patient/claimant) advised difficulties sustaining concentration, due to ongoing chronic pain."

Professor Cameron in his certificate dated 27 November 2020 whilst assessing concentration he documented: "On cognitive assessment [BPO] was incompletely oriented in time and place. She had limited recent memory and limited concentration. Using the Mini Mental State Examination she scored 18/30. This is not a valid score as these scores are seen only in people with dementia."

Dr Vickery in his report dated 3 December 2020, "There is reduced memory and concentration and "I (the claimant) struggle to find words for things and my short-term memory has become worse since the accident." he did not document how much was due to pain and how much was due to the assessable psychological injury.

Assessor Mason documented in his certificate dated 14/04/2022 in relation to her difficulty in concentration persistence and pace, "Some of this difficulty is due directly to pain..." The assessor did not document how much of her concentration, persistence and pace was due to pain, but he did document, "...but much of it is due to her anxiety and depression."

The claimant was observed to be experiencing pain throughout the re-examination. She had stood up at the 45 and 90 minute marks of the re-examination. She walked and stretched before returning to speaking and addressing the questions asked. She said she was unable to continue her studies due to pain which impaired her concentration, persistence and pace when attempting to engage in complex academic and business tasks. This is consistent with the findings of the clinical psychologist at the Northern Beaches hospital in 2019.

The loss of ability to perform complex tasks due to pain was not included in the assessment of impairment for this concentration, persistence and pace.

The Medical Assessors' observed pain-behaviours which did impaired the claimant's concentration, persistence and pace throughout the re-examination. The claimant's experience of pain was reported more when she began to suffer from difficulty concentrating at about 45 minutes. The claimant spoke about her difficulty to watch television and read which was impaired by pain.

The claimant said she was unable to continue to organise her small business due to her low energy and slow pace of task completion. She said she had her business placed in liquidation. She said she was unable to return to any of her small business tasks because of her persistent depressive symptoms. The claimant was erratic in her capacity to perform her business functions work duties. The Medical Assessors assessed a Class 4, severe impairment for the assessable psychological injury caused by the motor accident.

The claimant said she was in too much pain to work in her role that she performed before the motor accident. The loss of function due to pain was not included in the assessment of impairment for this table of functioning.

1. The Medical Assessors noted that the claimant had been diagnosed with various psychological conditions before the motor accident. The claimant said she had experienced the life events included within the documents and summarised earlier in these reasons. The claimant said she had been resilient and used medical and psychological services early. She said prior to the motor accident she had been successful in forming a new relationship which is now a permanent relationship with her husband and father of her daughters. She said she was progressing at a high-level working, studying and managing her small business, prior to the motor accident
2. The claimant said she was not permanently impaired by her the events she had experienced.
3. The Medical Assessors agreed that because the claimant was not impaired, the mere presence of psychological symptoms is insufficient to meet DSM-5-TR criteria for adjustment disorder or any other disorder. The claimant does not have a history that meets Criterion B1 or B2 for adjustment disorder or any type. For the above reasons the claimant does not have a per-existing adjustment disorder or any other DSM-5-TR condition before the motor accident. We do not consider that at the time of the motor accident the claimant had a pre-existing psychological condition assessable under DSM-5-TR.
4. For these reasons the Medical Assessor have not made any apportionment for pre-existing psychiatric impairment.

1. The claimant had received evidence-based psychiatric and evidence-based psychological treatment. The claimant was treated as a psychiatric inpatient of a psychiatric hospital due to her suicidal thoughts and attempt. The evidence-based treatment the claimant received has provided the claimant with mild improvement in her psychiatric symptoms as evidenced by her not requiring further hospitalisation for her psychological injury.
2. We have not considered the effects of treatment of the claimant's pain symptoms which are obviously chronic and significant and continue to affect the claimant's level of functioning.
3. For these reasons the Medical Assessor have adjusted the claimant's assessment of whole person impairment by 1% WPI.

1. The scores or value for the claimant's current condition are 2, 2, 2, 2, 3, 4 which gives a median of 2 and provides an aggregate score of 15 which translates to 8% whole person impairment (WPI). An additional 1% is made for the effects of treatment which produces a final score of 9% WPI.

1. The review is a new assessment of all matters with which the medical assessment is concerned.
2. The Panel, comprised of two specialist medical practitioners, is not required to choose between competing medical opinions and is required to form its own opinion: Insurance Australia Group Ltd v Keen[53] and Insurance Australia Ltd v Marsh.[54]
3. The Panel adopts the extensive reasons provided by the Medical Assessors. We confirm that the impairment is based on the evaluation at the time of the medical assessment (cl 1.21 of the Guidelines) and we have relied on the combined clinical expertise of the Medical Assessors when examining the claimant.
4. Clause 1.215 of the Guidelines appears under the heading for the assessment of "mental and behavioural disorders" and provides:

"The PIRS is not to be used to measure impairment due to somatoform disorders or pain."

1. The claimant had suffered and is suffering from extensive pain caused by the motor accident and has received substantial treatment for pain. The claimant had also experienced significant clinical side-effects from the pain treatment she had received.
2. The assessment guidelines for assessment of psychiatric whole person impairment requires the exclusion of impairment caused by physical condition and pain from all causes.
3. The assessment of CRPS is not part of the psychiatric assessment of WPI. The claimant was assessed as suffering from CRPS although latter diagnosis suggest that the required signs are no longer present. The absence of an ongoing diagnosis of CRPS does not mean that the claimant is not suffering from a pain condition.
4. Most clinicians use the internationally recognised Budapest criteria as the diagnostic basis for identifying CRPS. The Budapest criteria is not the same as the criteria provided by the Guidelines. The findings on examination required by the Guidelines to satisfy the diagnosis of complex regional pain syndrome are more stringent and require the presence of more symptoms and signs than those provided by the Budapest criteria. Furthermore, someone can suffer pain without being diagnosed as suffering from CRPS.
5. The claimant has reported significant pain levels since the motor accident which is clearly impacting on her current level of functioning. The Medical Assessors were careful in delineating between the effects of pain and the effects of the diagnosed psychiatric condition when assessing the particular class of the various PIRS.
6. There were findings within the opinion of Medical Assessor Mason that incorporated the effects of pain within the assessment of various PIRS categories. The insurer's submission on review identified aspects of the original assessment in three PIRS categories referencing pain. The claimant's response was that the Medical Assessor did not conduct the assessment "purely based on pain" which is an acknowledgement that aspects of pain were incorporated into the assessment of the level of functioning in the various PIRS.
7. Pain is referenced by the original Medical Assessor in the reasons for assessment of "self-care and personal hygiene", "social and recreational activities", "travel", "concentration, persistence and pace" and "adaptation". It is unclear from these reasons to what extent pain was included or excluded from the assessment process.
8. We have otherwise, for the reasons provided, expressly considered and disregarded the effects of pain when considering the extent to which the claimant is assessed under a particular class for each of the PIRS.[55]
9. We note the observations in Abdal v Insurance Australia Ltd[56] that a medical assessment only involves "the plaintiff taking about himself in response to the medical assessor's questions or prompts, and this was not said to be, nor was it likely to be, an intellectually demanding task or a task that involved complex instruction".
10. It is the Panel's view that this is not what occurs in a normal assessment by a Medical Assessor in assessing a psychologically injured claimant and is not what occurred in the assessment undertaken by the Medical Assessors of the Panel. What occurred here and usually occurs is that the questioning by the Medical Assessor(s) over an extended period requires a claimant to maintain concentration, respond consistently to questioning, stay focused and remain coherent. The responses lead to the clinical observations made by Medical Assessors in determining whether and to the extent the claimant presents as impaired under this PIRS category for concentration, persistence and pace. For example, a loss of focus or non-responsiveness is part of the routine diagnosis because impairment of concentration is part of the formulation in diagnosing various conditions such as post-traumatic stress disorder (Criterion E.5) and/or Major Depressive (Criterion A.8) under DSM5-TR. Further, we note that the clinical observation by Medical Assessors is a critical measure used in their assessment of a claimant.
11. The table for the assessment of the permanent impairment based on these reasons is set out herein.

Evidence based psychiatric and psychological treatment

The claimant reported that she had less energy and less interested in her selfcare and personal hygiene. She said she that she was able to shower independently. She her appetite was reduced, and she would skip meals. She was less interested in cooking. Her mother would bring food to the family.

The Medical Assessors assessed a Class 2, mild impairment for the assessable psychological injury caused by the motor accident.

The assessment of the claimant's concentration persistence and pace assessable to the psychological injury at the time of this assessment was assessed with consideration of forwarded documents regarding the contribution of the psychological injury to the assessable impairment of concentration, persistence and pace from the contribution of pain to the claimant's difficulties with respect to concentration, persistence and pace.

The Medical Assessors noted: At the time of the claimant was admitted to Northern Beaches hospital when her psychological injury requiring acute inpatient psychiatric treatment her treating psychiatrist Dr Peter Jones on 28/05/2019 for his clinical assessment of "... attention/concentrating, planning..." wrote that the claimant's functioning was "Grossly intact..." i

9%WPI = Percentage Whole Person Impairment (overall)

1. The claimant requested that the published reasons be de-identified.
2. The parties were then advised that due to the likelihood of stress we considered de-identifying the published reasons. The insurer advised that it consented to the de-identification of the published reasons.
3. These reasons contain sensitive personal information.
4. The reasons for de-identification relate to the claimant's psychiatric condition which has resulted hospitalisation and associated complications arising from this condition. We consider that it is likely that publication of the reasons will cause the claimant further trauma.
5. Having weighed the matters referred to in rule 132(4) of the Personal Injury Commission Rules, 2021 including the safety, health and wellbeing of the claimant, and whether the public interest in giving the direction significantly outweighs the public interest in open justice, we are satisfied that the decision should be deidentified before it is published.
6. Pursuant to Rule 132 of the Rules, the decision is to be de-identified prior to publication to include, at least, a pseudonym for the claimant.

1. The certificate issued by Medical Assessor Mason is revoked. A replacement certificate is attached at the commencement of these Reasons.
