STATEMENT OF REASONS
BACKGROUND
The claimant, Dina Aduah (Ms Aduah), was injured in a motor vehicle accident (the accident) on 14 August 2018.
Following the accident, she made a claim for damages under the Motor Accident Injuries Act 2017 (MAI Act) on NRMA (insurer).
A dispute has arisen between the claimant and the insurer about whether the degree of permanent impairment that has resulted from psychological injury caused by the accident is greater than 10%. The dispute is a medical dispute, as defined by s 7.17 of the MAI Act, and a medical assessment matter: Schedule 2 cl 2(a) of the MAI Act.
The medical dispute was referred to Medical Assessor Abhishek Nagesh for assessment. The Medical Assessor gave a certificate dated 23 November 2023 in which he certified that major depressive disorder and post-traumatic stress disorder were caused by the accident and gave rise to a permanent impairment (15%) that was greater than 10%.
The Review Panel (Panel) has been constituted by the President of the Personal Injury Commission (Commission) to conduct the Review of the Assessment.
THE REVIEW
The Panel is to conduct the Review in accordance with s 7.26 of the MAI Act. Section 7.26(5A) provides that the panel is to be constituted by two Medical Assessors and a member assigned to the Motor Accidents Division of the Commission.
The Review is not limited to a review of only that aspect of the assessment that is alleged to be incorrect and is to be by way of a new assessment of all the matters with which the medical assessment is concerned: s 7.26(6) MAI Act.
Rules 127 to 130 of the Personal Injury Commission Rules 2021 (Rules) are made pursuant to Part 5 of the PIC Act. The Panel determines how it conducts and determines the proceedings and may determine the proceedings solely based on the written application: Rule 128.
Version 9.2 of the Motor Accident Guidelines (Guidelines), effective from
10 November 2023, apply to the Review.
STATUTORY PROVISIONS
Permanent impairment
If there is a dispute about whether the degree of permanent impairment of an injured person is sufficient for an award of damages for non-economic loss, damages may not be awarded unless the degree of permanent impairment has been assessed by a medical assessor under Division 7.5: s 4.12(1) MAI Act.
The method of assessing the degree of impairment is dealt with in s 7.21, which is in the following terms:
“7.21 Assessment of degree of permanent impairment
(1) The assessment of the degree of permanent impairment of an injured person for the purposes of this Act is to be made in accordance with the Motor Accident Guidelines. The assessed degree of permanent impairment is to be expressed as a percentage.
(2) Impairments that result from more than one injury arising out of the same motor accident are to be assessed together to assess the degree of permanent impairment of the injured person.
(3) In assessing the degree of permanent impairment, regard must not be had to any psychiatric or psychological injury, impairment or symptoms, unless the assessment of the degree of permanent impairment is made solely with respect to the result of a psychiatric or psychological injury.
(4) A medical assessor may decline to make an assessment of the degree of permanent impairment of an injured person until the assessor is satisfied that the impairment caused by the injury has become permanent.”
Clause 6.35 of the Guidelines states that psychiatric impairment is assessed in accordance with ‘Mental and behavioural disorders’, found in cls [6.201]-[6.228] of the Guidelines.
Pre-existing impairment
Pre-existing impairment is addressed in cls 6.31-6.33 as follows:
“Pre-existing impairment
6.31 The evaluation of the permanent impairment may be complicated by the presence of an impairment in the same region that existed before the relevant motor accident. If there is objective evidence of a pre-existing symptomatic permanent impairment in the same region at the time of the accident, then its value must be calculated and subtracted from the current WPI value. If there is no objective evidence of the pre-existing symptomatic permanent impairment, then its possible presence should be ignored.
6.32 The capacity of a medical assessor to determine a change in physical impairment will depend upon the reliability of clinical information on the pre-existing condition. To quote the AMA4 Guides (page 10): 'For example, in apportioning a spine impairment, first the current spine impairment would be estimated, and then impairment from any pre-existing spine problem would be estimated. The estimate for the pre-existing impairment would be subtracted from that for the present impairment to account for the effects of the former. Using this approach to apportionment would require accurate information and data on both impairments.' Refer to clause 6.218 for the approach to a pre-existing psychiatric impairment.
6.33 Pre-existing impairments should not be assessed if they are unrelated or not relevant to the impairment arising from the motor accident.”
Clause 6.35 of the Guidelines states that psychiatric impairment is assessed in accordance with “Mental and behavioural disorders” within the Guidelines, namely cls [6.201]-[6.228] of the Guidelines.
In order to measure impairment caused by a specific event, a Medical Assessor must, in the case of an injured person with a pre-existing psychiatric diagnosis or diagnosable condition, estimate the overall pre-existing impairment using precisely the method set out in the Guidelines, and subtract this value from the current impairment rating: cl 6.218.
Causation
The Guidelines state as follows with respect to causation of injury:
“Causation of injury
6.5 An assessment of the degree of permanent impairment is a medical assessment matter under clause 2(a) of Schedule 2 of the Act. The assessment must determine the degree of permanent impairment of the injured person as a result of the injury caused by the motor accident. A determination as to whether the injured person's impairment is related to the accident in question is therefore implied in all such assessments. Medical assessors must be aware of the relevant provisions of the AMA4 Guides, as well as the common law principles that would be applied by a court (or the Personal Injury Commission) in considering such issues.
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:
(a)The alleged factor could have caused or contributed to worsening of the impairment, which is a medical determination.
(b)The alleged factor did cause or contribute to worsening of the impairment, which is a non-medical determination.'
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.”
It is necessary for the Panel to consider whether the accident caused or contributed to the diagnosed psychiatric condition: Briggs v IAG Limited t/a NRMA Insurance [2022] NSWSC 372 at [75]. The motor accident does not have to be the sole cause as long as it is a contributing cause, which is more than negligible: Owen v Motor Accidents Authority of NSW [2012] NSWSC 650 at [50]. Further, the provisions of the Civil Liability Act 2002 apply, in particular s 5D and s 5E.

At [17] of his Certificate, Medical Assessor Nagesh sets out a summary of the relevant documentation he considered in his assessment.
Medical Assessor Nagesh sets out his diagnosis, causation and reasons at [18]-[19] of his certificate:
“[18] In my opinion Ms Aduah meets the criteria for Major depressive disorder as follows. She has experienced depressive and anxiety symptoms in the context of her pain, not able to be active as before and loss of mobility. She fulfils the criteria under DSM V as follows. Five of the following symptoms have been present for more than two weeks where on of the symptom is depressed mood. In addition she has experienced insomnia, lack of energy and motivation, fluctuating appetite, diminished ability to concentrate, fleeting suicidal thoughts, feelings of worthless.
· Symptoms have caused impairment in socio occupational functioning and significant distress.
· The symptoms are not due to any physiological effects of substance or medical condition.
· The occurrence of Major depressive episode is not explained by a another mental disorder.
· There has been no manic or hypomanic episode.
Ms Aduah meets the criteria for PTSD as follows
· She has been exposed to a MVA where she was hit by a car while she was a pedestrian, developed serious injury of her knee as a consequence of the MVA. I note she has not lost consciousness, there was no head injury but the accident was severe enough to meet the definition of trauma in my clinical judgement.
· Developed intrusion symptoms which include nightmares and flashbacks.
· Avoided walking past the accident site, has relocated to another suburb as the accident site was two minutes away from where she lived. Relocated to avoid the accident site.
· Negative alterations in cognitions- which include depressed mood, loss of interest in her hobbies which include sewing, dancing. Anger towards the driver who caused the accident. Nothing makes her happy at the moment.
· Arousal symptoms which include- Irritability, diminished ability to concentrate, insomnia.
· The symptoms have been present for more than a month.
· Symptoms have caused impairment in socio occupational functioning and significant distress.
· The symptoms are not due to any physiological effects of substance or medical condition.
[19] Ms Aduah has no previous history of mental illness. The subject MVA was a traumatic incident where Ms Aduah was exposed to death. In my opinion the subject MVA has resulted in her diagnosed PTSD. The pain the functional limitations from her physical injuries has given rise to her Major depressive disorder.”
Medical Assessor Nagesh sets out the degree of permanent impairment using the psychiatric impairment rating scale (PIRS) at [22] of his certificate:
Psychiatric diagnoses
1. Post traumatic Stress
disorder
2.Major depressive disorder
3.
4.
Psychiatric treatment description
Pharmacotherapy, CBT, Supportive psychotherapy.
Category
Class
Reason for decision
1. Self Care and Personal Hygiene
2
If not for pain and her physical injury she would be capable of living independently but would struggle due to her depressive and PTSD symptoms and hence in my clinical judgement her level of impairment is of mild degree and hence she scores 2.
2. Social and Recreational Activities
3
Remain socially withdrawn, has lost contact with majority of friends, does not attend any weddings, dinner parties, or anniversaries. Cannot attend large group events due to anxiety.
3. Travel
2
Dina is able to go out for walks on her own for ten minutes, she is able to take public transport independently where she can travel up to ten minutes on her own but she cannot travel to far away and unfamiliar places without her daughter.
4. Social Functioning
2
Has lost contact with majority of friends, not in any relationship, but has no interest to form a new relationship, relationship with daughter remains intact.
5. Concentration, Persistence and Pace
3
Her attention, concentration remains poor, she is not able to read a book, watch TV or read magazines, which is due to her depressed mood, cannot focus for more than five minutes.
6. Adaptation
3
Her inability to work is partly due to her pain and her physical injury and using my clinical judgement her inability to cope with stress and work at the moment is of moderate degree and she scores 3
List classes in ascending order: 2,2,2,3,3,3
Median Class Value: 2.5=3
Aggregate Score: 15
% Whole Person Impairment: 15%
15*%WPI = Percentage Whole Person Impairment
Medical Assessor Nagesh sets out apportionment at [23] of his certificate:
“[23] There is no pre existing condition and hence there is no pre existing impairment. Ms Aduah has burnt herself and had a fall in her kitchen in January 2023. This injury has worsened her pain but has not given rise to any new psychological injury. Her PTSD and Major depressive disorder are from the subject MVA and I have not deducted any portion for subsequent impairment.”
EVIDENCE
The parties have provided respective bundles of evidence relied on in the Review. The bundles from the claimant and the insurer include MRI scans, medical and medicolegal reports, and clinical notes. The Panel has considered all this material.
The Application for Personal Injury Benefits form dated 29 October 2018 contains a description of the accident:
“I crossed the road at Elizabeth Drive in Liverpool, from the side of the McDonald’s Restaurant. I looked for cars before crossing and could not see any cars. After commencing to cross the road, as I was about to step onto the median strip, a car hit my right leg and I fell to the ground.”
And lists injuries to the:
“right knee, right leg, psychological.”
The Panel refers to the ambulance report dated 14 August 2018 which notes in the case description that the claimant was crossing the road when she was struck by a motor vehicle travelling at approximately 70kmph. She denies hitting her head and denies any loss of consciousness or cervical spine tenderness. The claimant was alert, orientated and denies any other pain other than to the lateral right knee.
The Panel refers to the Police Report dated 21 February 2019 which contains a summary of the accident:
“On 14th August 2018, Unit 2 (pedestrian) crossed the southern kerb of Elizabeth Drive at McLean Street, walking across westbound lanes 1 and 2 of 3, intending to stop at the median strip in the centre of Elizabeth Drive.
Unit 2 then continued walking through lane 3, during which time DR 1, travelling in lane 3, collided with Unit 2. It is believed Unit 2 was about 30 cm short of reaching the median strip when DR 1 collided into her.
The area where the pedestrian crossed is not controlled by traffic lights or a pedestrian crossing.
All details were exchanged between both parties. Unit 2 was conveyed by ambulance to Fairfield Hospital for treatment.”
SUBMISSIONS
Submissions by the insurer of 12 December 2023
The Panel summarises the submissions of the Insurer dated 12 December 2023 as follows:
Background
The insurer’s grounds for review are:
· Medical Assessor Nagesh erred in assessing Ms Aduah’s post-traumatic stress disorder as giving rise to 15% whole person impairment (WPI);
· Medical Assessor Nagesh erred in his PIRS assessment, and
· the assessment is incorrect in a material respect.
The insurer submits that a correct assessment would have resulted in a finding of less than 10% WPI.
Submissions
The insurer submits that the PIRS assessment was incorrect.
Medical Assessor Nagesh diagnosed Ms Aduah with major depressive disorder and post-traumatic stress disorder, resulting in 15% WPI.
Self-Care and Personal Hygiene
Medical Assessor Nagesh rated mild impairment, noting Ms Aduah relies on her daughter and struggles due to pain and psychological symptoms.
The insurer submits the reported domestic limitations are due to physical, not psychological causes.
Ms Aduah reported to Dr Prior that she cooks twice a week, showers and changes daily.
Referring to the history taken by Medical Assessor Nagesh, the insurer submits the correct rating is Class 1.
Social and Recreational Activities
Medical Assessor Nagesh rated moderate impairment, stating Ms Aduah is socially withdrawn.
Dr Prior reported Ms Aduah recently reconnected with a friend and avoids social outings due to pain and lack of motivation.
The insurer submits it is unclear whether her withdrawal is due to psychological or physical factors, and that Class 3 is not justified.
Travel
Medical Assessor Nagesh assessed mild impairment, stating Ms Aduah can walk and use public transport for short distances.
This is consistent with Dr Prior’s history; she travels independently to appointments.
The insurer submits her limitations are physical, not psychological, and there is no psychological deficit for travel.
Social Functioning
Medical Assessor Nagesh found mild impairment, stating Ms Aduah has no relationships but a good relationship with her daughter.
The insurer submits that this contradicts Dr Prior’s 2022 report that Ms Aduah was married, with a “very good” relationship and living with her daughter.
The insurer submits Class 2 is not justified and that Ms Aduah has no impairment in this domain.
Concentration, Persistence, and Pace
Medical Assessor Nagesh rated moderate impairment, stating Ms Aduah cannot concentrate or watch TV due to depression.
During assessment, Ms Aduah was engaged, oriented, and communicative.
Dr Prior recorded she watches TV and news daily, including African movies for hours.
The insurer submits this contradicts a Class 3 rating and is inconsistent with PIRS criteria and observed behaviour.
Adaptation
Medical Assessor Nagesh found moderate impairment, stating Ms Aduah cannot work due to pain and inability to cope with stress.
He noted pre-accident employment but gave no detail on post-accident work capacity.
The insurer submits there is no evidence as to Ms Aduah’s current ability to work or how her psychiatric condition affects it.
The insurer submits there is insufficient reasoning to support a Class 3 rating.
Submissions by the claimant of 14 December 2023
The Panel summarises the submissions of Ms Aduah dated 14 December 2023 by reference to paragraph numbers:
Self-care and personal hygiene:
[1] Ms Aduah submits that the PIRS is a guideline, not a definitive test. Medical assessors are entitled to exercise clinical judgment and consider symptoms not expressly listed in the PIRS tables.
[2] Ms Aduah submits the insurer’s position that Ms Aduah should be rated Class 1 overlooks Assessor Nagesh’s recorded history, including fatigue, hopelessness, suicidal ideation, and inactivity, which are all relevant to psychological functioning.
[3] Ms Aduah submits the Class 2 rating appropriately reflects both psychological symptoms and physical limitations impacting Ms Aduah’s self-care.
[4] Ms Aduah submits a change from Class 2 to Class 1 would not materially affect the overall impairment.
Social and Recreational Activities:
[5] Ms Aduah submits the insurer has not substantiated its allegation that Assessor Nagesh gave inadequate reasoning for a Class 3 rating.
[6] The assessment must be read holistically, not cherry-picked. Ms Aduah submits that pages 4 and 5 of the certificate, including "current functioning" and "diagnosis and reasons," support the assessor’s reasoning.
[7] Ms Aduah addresses the insurer’s comment regarding the basis of social withdrawal, noting that it is both physical and psychological.
[8] Ms Aduah submits her multi-faceted injuries have elements of physical and psychological complaints, and this is acknowledged by several doctors, including Dr Prior, who notes a lack of motivation.
Travel:
[9] Ms Aduah notes the insurer raises no error in this category.
Social Functioning:
[10] Ms Aduah submits that a Class 2 rating is appropriate based on her loss of motivation to engage socially. A good relationship with her daughter does not reduce the rating to Class 1.
[11] The insurer itself notes that she "has lost contact with the majority of her friends."
[12] Regardless, Ms Aduah submits the Class 2 rating does not materially alter the overall assessment.
Concentration, Persistence, and Pace:
[13] Medical Assessor Nagesh recorded that Ms Aduah cannot read a book or watch TV due to poor concentration and depressed mood.
[14] The insurer relies on Dr Prior’s report, but this report actually supports a Class 3 impairment.
[15] Dr Prior documented Ms Aduah’s forgetfulness, reliance on others for reminders, and frequent misplacement of items.
[16] Ms Aduah submits that the certificate, when read as a whole, justifies a Class 3 rating based on Ms Aduah’s psychiatric condition.
Adaptation:
[17] The insurer claims Medical Assessor Nagesh provided no employment-related justification for a Class 3 rating.
[18] Ms Aduah submits that this is incorrect. The certificate, when read holistically, demonstrates the rationale behind the Class 3 impairment. Multiple references across pages 2–4 detail the psychological impact of the accident, including:
·no prior mental illness;
·pre-accident employment;
·ongoing symptoms including flashbacks, nightmares, depression, and avoidance behaviour;
·ongoing psychological treatment and medication, and
·daily inactivity, diminished concentration, suicidal ideation, and relocation due to trauma triggers.
[19] Ms Aduah submits that the certificate shows the Medical Assessor did not rely solely on a declaration of clinical judgment but substantiated it through detailed medical reasoning.
[20] Ms Aduah further submits that a Class 3 impairment for Adaptation is justified.
RE-EXAMINATION BY THE PANEL
Medical Assessor Samson Roberts and Medical Assessor Ankur Gupta assessed
Ms Aduah on behalf of the Panel via Microsoft Teams on 27 March 2025. The Panel provides the report below:“Who attended the assessment
The assessment was undertaken using Microsoft Teams. Ms Aduah participated in the interview from her home. Her daughter, Rebecca Douku was present as her support person.
Psychosocial history and pre-accident history
Ms Aduah is a 62-year-old woman. She described herself as single. She has a 22-year-old daughter. Ms Aduah resides in Casula with her daughter and her niece, namely her sister’s daughter. Ms Aduah stated that she last worked in 2019 following a motor accident. Her daughter works full time as does her niece.
Ms Aduah grew up in Tamma in Ghana. She is the eldest of five siblings. Her mother was a trader and her father worked in computers. She spoke positively of her relationship with her parents and with her younger siblings. She attended school until Year 7. She found school academically challenging. She had friends and she did not recount any behavioural or disciplinary issues. Having left school, she learned to sew. She met her husband in Ghana and her daughter was born in Ghana.
Her husband died of a heart attack in 2016 at age 72 or 73 years.
In 2006, Ms Aduah moved to Australia. Her husband was already living in Australia and working as a taxi driver. She obtained employment, sewing in a factory for four or five years. She worked in a casual capacity, up to ten hours per day. When the factory reduced its work, she sought employment as a cleaner at the airport. She commenced the role in 2018 which entailed cleaning inside aircraft.
Ms Aduah clarified that she applied for the job prior to the subject motor accident and undertook the requisite training. She was to work casual hours. She was hit by a car in the subject motor accident one day before commencing her role.
Ms Aduah clarified that she had not been working prior to attaining this role and was in fact looking for employment. She had been the carer for her husband until his death in 2016 for which she obtained payments from Centrelink. She stated that before the motor accident, she managed the house and undertook the cleaning. When her husband was alive, she would take him for walks. Her focus was primarily on family rather than pursuing other social contacts.
Ms Aduah did not report any previous injuries. She delivered her daughter via Caesarean due to her daughter’s large size. She did not experience any complications. She has never been a smoker. She did not report having used alcohol or illicit drugs.
Ms Aduah did not report ever being involved in any prior motor accident or a subsequent motor accident.
History of the motor accident
Ms Aduah explained that she was crossing a road at the time of the motor accident. She had nearly arrived at the other side of the road when the vehicle hit her right leg. She recalled that she fell on her right side. She sought to protect her head with her right hand. She had not seen the car coming.
Ms Aduah recalled that the car travelled on a short distance before stopping.
Ms Aduah recalled that she experienced a severe pain in her leg. Staff from the nearby McDonald's called an ambulance. She had landed on the ‘pavement’. Bystanders assisted her into a chair.History of symptoms and treatment following the motor accident
Ms Aduah stated that she was told by ambulance officers, ‘No one survives this accident.’ She did not explain to what they were referring. She was conveyed to Fairfield Hospital. She recalled undergoing radiological assessment. She was given a letter for her general practitioner and she obtained a referral for an MRI scan. She has seen a pain specialist, physiotherapist, psychologist and counsellor.
Two years after the accident, in 2020, Ms Aduah underwent a surgical procedure. She explained that her kneecap had moved and she was experiencing severe pain, swelling and a dragging sensation. The surgery entailed a realignment of her patella. Three days after the operation, she developed a pulmonary embolus. She stated that she nearly died. She was prescribed anticoagulants which she took until two months prior to the interview. She stated that the clot remains in situ but it has changed over time. She recalled that the anticoagulant was Eliquis.
Details of any relevant injuries or conditions sustained since the motor accident
Ms Aduah was admitted to hospital in 2024. As stated above, she reported that this admission was an effect of excessive medication. It was not apparent that this event was of psychiatric relevance.
Current symptoms
With respect to her physical condition, Ms Aduah stated that she continues to experience pain and swelling of her knee. On occasion, her knee collapses. She requires the use of a walking stick and, when she walks on stairs, she must go ‘one by one’.
Ms Aduah did not report any past psychiatric history but expressed frustration in relation to her current physical limitations. She stated that she cannot do the things that she would like and she finds herself ruminating. She stated that the accident has ruined her life. Previously, she was very active while now she needs help with day-to-day tasks.
Ms Aduah reported that she is no longer a happy person. She reiterated frustration at the extent to which she is reliant on her daughter and, in this context, she feels sad. She told me she remains a calm person despite her frustration. She sleeps three to four hours, attributing her limited sleep to her tendency to reflect on her physical inactivity. Sometimes she feels bored. She stated that she would engage in more activities if not for the physical limitations. She spends time with her daughter but sometimes she is not in a frame of mind to talk.
When asked what plays on her mind, Ms Aduah replied that she worries about her daughter and she worries about the extent that she is sitting at home. She did not express any particular concerns regarding her daughter’s circumstances other than the extent to which her daughter is required to assist her. She also finds herself thinking about her life in general and she thinks about the motor accident, for example when she closes her eyes.
Ms Aduah stated that she is now very careful when she crosses a road. She uses a zebra crossing or pedestrian lights or, if required to cross where there are no crossing facilities, she will go slowly.
Ms Aduah initially stated that her memory is poor but then said that it is in fact ‘so so’. Similarly, her concentration is suboptimal but she will nevertheless watch a movie. She is perpetually affected by pain despite which she travelled to Ghana where she enjoyed seeing family.
Ms Aduah was asked regarding matters identified in the documents. She confirmed that she had remarried and then separated. It was put to her that there is reference to engagement in IVF treatment in Africa. Ms Aduah denied having participated in any such treatment. With respect to her work history, she confirmed that she in fact undertook casual employment at the airport as a cleaner despite the reported issues with her leg. She persisted in this role until the surgery of 2020. She explained that she was enduring significant financial issues at the time which compelled her to work. She also confirmed an admission to hospital in 2024. She stated that she had not in fact sustained a head injury and she stated that the fall was attributed to excessive medication.
Current and proposed treatment
Currently, Ms Aduah is prescribed medication which includes Panadol two tablets three times daily, Lyrica 25mg twice daily, amitriptyline 10mg twice daily, Minipress 2mg twice daily and Olmesartan the dose of which she did not state. She explained that she was previously on more medication but there has been no change in her medication regimen for six years.
Ms Aduah confirmed that she sees a pain specialist, Dr Daniel in Parramatta and a physiotherapist who is also in Parramatta. She takes the train or if she feels particularly compromised with respect to her ability to walk, she attends by Uber.
Ms Aduah named her psychologist as Maria. Ms Aduah travels by bus to see her monthly. When asked regarding the nature of the therapy, Ms Aduah stated that Maria asks questions and they talk.
CLINICAL EXAMINATION
Mental state examination
As stated above, Ms Aduah was assessed using audiovisual technology. The quality of the connection was satisfactory. She presented as a neatly groomed woman of African ethnicity. She wore earrings. She did not exhibit psychomotor agitation or retardation as may arise in the context of an acute psychiatric condition. She presented a restricted range of emotional expression. Her account indicated a dysthymic mood. Frustration with her limited physical abilities represented a prominent theme. She spoke with a strong accent. Her speech was normal in terms of rate, tone and volume. The use of language was straightforward, consistent with her level of education. She did not demonstrate any difficulty making herself understood at interview. She described reflecting on the motor accident and described caution when crossing roads. She did not describe overt intrusion symptoms nor did her account indicate avoidance behaviour or hypervigilance. No features of a psychotic nature were apparent.
Current functioning
As stated above, Ms Aduah is not currently employed. She worked following the motor accident, ceasing work at the time of the surgery. She stated that she last worked in 2019 but she dated the surgery to 2020. She explained that her daughter manages the household. Her daughter cooks. Ms Aduah warms up food for herself. She explained that she is restricted in her ability to participate in household tasks because she cannot stand for periods of time. She is however able to put on the laundry. She cannot manage the weight of wet clothes. She cannot vacuum or mop.
Ms Aduah is able to shower herself and dress herself. She uses a stool in the shower. She showers every day and she gets dressed every day. She eats three meals a day. Her daughter oversees the household bills.
When asked how she spends her time, Ms Aduah replied that she spends much of the time lying down. She attends her appointments by Uber, bus or a train. She has never driven. She uses her walking stick to assist her to walk from her home to the bus stop, three minutes away. At the railway station, she uses a lift. Physical limitations undermine her ability to use the stairs.
In terms of other recreational activities, Ms Aduah watches television. She has no friends who visit her and she does not visit others. She goes out with her daughter every month to a nearby coffee shop. She spoke positively of her relationship with her daughter and her niece. She has no other family in Sydney. She maintains contact with family in Ghana. They ring her and she rings them. She last saw them about two years ago when she travelled to Ghana. She flew alone via Dubai. She arranged wheelchairs at each airport. She reiterated that she cannot sit or stand for long periods because her feet become swollen and she is reliant on her walking stick.
Comments on consistency
No inconsistencies were identified with respect to Ms Aduah’s account nor were there inconsistencies in mental state examination. There were however inconsistencies between her account and the information contained within the documents.
Diagnosis and reasons
The medical assessors noted the discrepancies between Ms Aduah’s account and the information contained in the documents, in particular in relation to her engagement in IVF. This discrepancy could not be explained. As documented above, the medical assessors clarified Ms Aduah’s work history. Namely, she explained that she had worked for a period of time following the motor accident in a casual cleaning role until the time of her surgical procedure.
The history included significant frustration, irritation and distress in the context of chronic pain and physical compromise. The assessors found that Ms Aduah had developed a depressed mood and other symptoms indicative of a depressive condition of protracted course. Based on the history provided by her, the medical assessors concluded that the most appropriate diagnosis, having regard for the criteria stipulated in DSM-5, was that of Persistent Depressive Disorder.
The medical assessors considered the possible diagnosis of post-traumatic stress disorder. They concluded that the motor accident was not of a nature consistent with a Criterion A trauma as stipulated in DSM-5 nor did they find that other diagnostic criteria were met.
Causation and Reasons
The medical assessors noted the absence of any pre-existing psychiatric diagnosis and the absence of any subsequent events of a nature that could be considered to have contributed to the causation of the diagnosed condition. The relationship between the chronic pain and physical limitations ascribed to the motor vehicle accident led the medical assessors to conclude that the motor accident had caused the psychiatric injury.
Permanency of impairment
Permanent impairment is defined in the American Medical Association’s Guides to the Evaluation of Permanent Impairment (Fourth Edition) (p 315) as follows:
‘Permanent impairment is impairment that has become static or well stabilised with or without medical treatment and is not likely to remit despite medical treatment.
A permanent impairment is considered to be unlikely to change substantially and by more than 3% in the next year with or without medical treatment.’
Given the protracted course, severity and approach to treatment, the medical assessors considered that Ms Aduah’s psychiatric condition was unlikely to change substantially and my more than 3% in the next year.
| Psychiatric diagnoses | 1. Persistent Depressive Disorder | 2. |
| 3. | 4. | |
| Psychiatric treatment description | Psychological therapy | |
| Category | Class | Reason for Decision |
| 1.Self-care and Personal Hygiene | 1 | Ms Aduah reported consistent attention to her personal hygiene. She ascribed her limited participation in household tasks to factors of a non-psychiatric nature. She eats three meals a day. She prepares food for self to the extent that she is able physically. Her presentation at interview was consistent with her account of attention to personal care. |
| 2.Social and Recreational Activities | 2 | Based on Ms Aduah’s account, she has always been one to focus preferentially on family rather than pursuing social relationships. She described a constrained lifestyle and attributed this to factors of a physical nature. She reported undertaking outings for coffee with her daughter on a monthly basis. Her ability to undertake independent outings and her attribution of limitations in this regard to factors of a physical nature, was noted by the medical assessors. Irrespective of her description of physical constraints on her participation in recreational activities outside the home, the medical assessors considered that the nature and severity of her psychiatric diagnosis was such that she would be mildly impaired for psychiatric reasons irrespective of other factors. |
| 3.Travel | 1 | Ms Aduah has never driven. She uses public transport independently to attend her appointments. She travelled to Ghana via Dubai independently, albeit with assistance due to her physical limitations. Ms Aduah expressed heightened caution when crossing the road but she did not describe limitations with respect to her ability to do so. No information was identified to indicate psychiatric compromise with respect to travel. |
| 4. Social Functioning | 2 | Based on the history obtained, it was apparent that Ms Aduah formed an intimate relationship and then separated since the accident. She spoke positively of her relationships in particular with her daughter and her niece. She maintains consistent contact with family overseas. The medical assessors considered her relationship history, noting the failure of an intimate relationship but also noting her ability to establish one. Overall, it was apparent that Ms Aduah is mildly impaired in this area. |
| 5.Concentration, Persistence and Pace | 2 | Ms Aduah participated effectively in the interview, demonstrating no difficulties with respect to concentration or memory notwithstanding her comment during the interview that she is somewhat compromised. The medical assessors noted that Ms Aduah presented her physical symptoms as a prominent impediment to her general functioning but concluded that the nature of her psychiatric symptomatology was such that it would be expected to confer mild psychiatric impairment in this area. |
| 6. Adaptation | 2 | As stated previously, Ms Aduah identified physical symptoms as the overwhelming limitation on her day-to-day functioning. The medical assessors noted that she had returned to work for a period of time after the accident despite her symptoms. Relying on clinical experience, the medical assessors concluded that the psychiatric condition would cause mild impairment in this area of functioning independent of non-psychiatric factors. |

Apportionment
As specified in paragraphs 7.14 and 7.15 of the Guidelines, only those aspects of impairment attributable to psychiatric factors may be considered in the calculation of psychiatric whole person impairment. Namely, impairment arising as a result of pain and physical compromise has been excluded from the assessment of psychiatric whole person impairment.
Pre-existing and subsequent
No information was identified to indicate pre-existing or subsequent impairment.
Effects of treatment
It was not evident to the medical assessors that the psychological treatment in which Ms Aduah is participating would influence the severity of her symptoms or her psychiatric impairment. Although the medical assessors noted that she is currently prescribed a tricyclic antidepressant, the dose is so low that it would not be expected to produce any therapeutic effect. Therefore, no adjustment for the effects of treatment is required.
A Current % permanent impairment 5%
B Pre-existing/subsequent % permanent impairment 0%
C Adjustments % for effects of treatment 0%
Final % permanent impairment 5%
The medical assessors identified psychiatric whole person impairment caused by the accident that is not greater than 10%.”
DETERMINATION
The Review Panel revokes the certificate of Medical Assessor Nagesh, dated
23 November 2023, and substitutes the determination to certify that the injuries referred to the Panel and caused by the motor accident, gave rise to a WPI of 5%.
