Regulation respecting the impairment scale
WORKMEN’S COMPENSATION — IMPAIRMENT SCALE
Workers’ Compensation Act
(chapter A-3, s. 124, par.
m
)
.
A-3

2012
Subject to the following paragraph, chapter A-3 is replaced by the Act respecting industrial accidents and occupational diseases (
chapter A-3.001
) (1985, c. 6, s. 476).
The Workers’ Compensation Act (
chapter A-3
), amended by sections 479 to 483 of the Act respecting industrial accidents and occupational diseases and the regulations made under chapter A-3, remain in force:
(
1
)
for the purposes of the processing of claims made for industrial accidents and deaths that occurred before 19 August 1985 and for claims made before that date for occupational diseases, except in the case of a recurrence, relapse or aggravation contemplated in the first paragraph of section 555 of chapter A-3.001;
(
2
)
for the purposes of every classification of industries and employers’ assessment carried out for a year prior to 1986, subject to sections 580 and 581 of chapter A-3.001;
(
3
)
for the purposes of the application of the Act to promote good citizenship (
chapter C-20
) and the Crime Victims Compensation Act (
chapter I-6
).
1
.
In this Regulation, unless the context indicates otherwise,
“
accident victim
”
means a worker who is the victim of an accident, occupational disease, or aggravation within the meaning of the Workmen’s Compensation Act (
chapter A-3
);
“
impairment
”
means the medically established sequelae, including disfigurements, of an injury that adversely affect an accident victim’s physical or psychic integrity;
“
major deterioration
”
means a sequela referring to wide, discoloured or hyperpigmented scars caused by lacerations, burns or a considerable loss of tissue;
“
disfigurement
”
means a noticeable sequela, other than functional damage, on the face, neck or other part of the body in the case of major deterioration covering more than 3% of the surface area of the body and constituting a loss of physical integrity. However, linear scars, whether surgical or nonsurgical, on any part of the body, including scars of the face and neck oriented in the direction of the lines of tension of the skin, are excluded.
O.C. 1948-82, s. 1
.
2
.
The impairment percentage of an accident victim whose physical integrity is adversely affected is determined in accordance with Titles I to XI of Schedule A.
However, for an injury not listed in Titles I to X of that Schedule, the evaluation is made by comparing the injury to similar injuries listed in the Scale.
O.C. 1948-82, s. 2
.
3
.
The evaluation of the percentage of an impairment other than a disfigurement is made upon the healing of the wound, taking into account the nature and the functional consequences of the injury, and the effectiveness of the prosthesis or orthesis, but disregarding the socio-occupational consequences that the sequelae of the injury may entail for the accident victim.
O.C. 1948-82, s. 3
.
4
.
The impairment percentage of an accident victim with multiple injuries other than disfigurements is determined by totalling the percentages prescribed for each impairment resulting from those injuries.
However, the sum of those percentages may not exceed the percentage prescribed for a segment, an extremity or the individual as a whole.
O.C. 1948-82, s. 4
.
5
.
The overall impairment percentage granted to an accident victim with nondisfiguring injuries to symmetrical organs is determined by totalling the percentages of the impairments resulting from each injury and by adding the lowest of those percentages thereto.
Where an accident victim is already handicapped because of a previous accident, a congenital disability or a pathological condition, the sequelae of the previous injury are evaluated exclusively for the purpose of the computation referred to in the preceding paragraph.
O.C. 1948-82, s. 5
.
6
.
Disfigurement is evaluated by taking into account the percentages set down in Title XI or the table of body surfaces in the Rule of 9.
O.C. 1948-82, s. 6
.
7
.
The noticeable multiple injuries of an accident victim resulting in disfigurement are globally evaluated for each of the anatomical regions listed in Title XI.
The global percentage granted is obtained by totalling the percentages granted for each of the anatomical regions involved.
O.C. 1948-82, s. 7
.
8
.
Despite section 5, no enhancement factor for the disfigurement percentage is granted for bilateral injuries or where symmetrical body areas are affected.
O.C. 1948-82, s. 8
.
9
.
Disfigurement is evaluated within a 12-month period after the accident victim’s condition has stabilized.
The percentage is set on the basis of:
(
1
)
the state of the injury at the time of the evaluation, or
(
2
)
the improvement anticipated, taking into account the possibilities of medicine or surgery.
O.C. 1948-82, s. 9
.
10
.
The percentage granted for impairment, including disfigurement, applies to the whole body of the accident victim and may not exceed 100%.
O.C. 1948-82, s. 10
.
11
.
This Regulation replaces Regulation respecting the impairment table (R.R.Q., 1981, c. A-3, r. 3).
O.C. 1948-82, s. 11

)
hand
With the exception of the thumb, where 2 or more fingers are completely or partially amputated, the impairment percentage of those fingers is obtained by adding the impairment percentage of each of the fingers and multiplying by 2.
Furthermore, where there is amputation or equivalent thereof of 4 fingers of the same hand, 0.2% is added for each of the 2 distal phalanges and 0.1% for the proximal phalanx.
Where the thumb is also amputated, its impairment percentage is added to the impairment percentage of the amputated finger together with the enhancement factor of the lesser of the 2 if only one finger is amputated. The percentage for the amputated thumb is added without the enhancement factor if several fingers are amputated.
N.B.:
Hand already subjected to a previous amputation or equivalent thereof.
Where a person’s hand was already impaired at the time of the accident, the above rules apply. The sequelae relating to the previous accident are evaluated only in order to establish whether they warrant an enhancement factor and are not included in the addition of the impairment percentages attributed to the recent sequelae.

INCONSPICUOUS IMPAIRMENT OF VENTILATORY FUNCTION
A basic impairment percentage (5%) is granted to any accident victim with radiological pathognomonic signs of amianthosis or silicosis recognized by the Commission des normes, de l’équité, de la santé et de la sécurité du travail but not showing up in any significant way in ventilatory function tests.
N.B.:
— The relationship is recognized between pulmonary neoplasia and asbestos fribrosis.
— A cause-and-effect relationship is recognized between death caused by mesothelioma and previous exposure to asbestos fibre.
— A relationship is recognized where an accident victim with asbestosis fribosis develops cancer of the digestive tract, pharynx or larynx.

IMPAIRMENT OF VENTILATORY FUNCTION
Impairment of ventilatory function may occur as a result of an impairment of any kind of the pulmonary function. Posttraumatic impairment of ventilatory function is never isolated in the case of an accident. The neurological aspect is evaluated according to Title II of this Scale. The traumatic aspect must be evaluated by a pneumologist, in view of daily activities and according to the following criteria:
(
a
)
clinical criteria, objective and subjective
— dyspnea I to V (international classification)
— cough
— sputum
— orthopnea
— bronchial and parenchymatous rales
— general physical examination
— chest pain
— hemoptysis
— pulmonary history
— occupation
(

)
objective criteria
i
.
roentgenography
oblique, lateral and posteroanterior high-voltage X-rays are taken for the examination of the
— pulmonary parenchyma
— condition of the heart
— pleura
ii
.
respiratory physiology
— basic
— pulmonary volumes
— expiratory flow rates
— maximal respiratory flow rates
— diffusing capacity at rest
— gas exchange at rest
— optional and according to each specific case
— gas exchange studies after exertion; Jone’s stages I and III for cases of pneumoconiosis
— measure of pulmonary elasticity (lung compliance) used in all cases of a first claim for asbestosis
— bronchial provocation challenges in cases of occupational asthma
(
c
)
principal criteria for diagnosing
i
.
asbestosis
— history of sufficient exposure to asbestos
— evidence of restricted pulmonary function in tests of ventilatory function
— progressive exertional dyspnea
— inspiratory crackling rales at lung bases
— clubbing of the fingers
— small, irregular category I opacities on pulmonary radiograph consistent with asbestos fibrosis, according to the 1971 ILO/UC classification
— signs of interstitial fibrosis with a sufficient number of fibres or ferruginous bodies appearing upon histological examination
ii
.
silicosis
— history of sufficient exposure to silica dust
— progressive exertional dyspnea
— small rounded opacities on the chest radiograph of at least category 1 according to the ILO/UC 1971 classification
— histological findings consistent with silicosis upon microscopic examination of lung tissues.
N.B. All the criteria described above respecting asbestosis and silicosis are not needed to diagnose the 2 diseases.
It should be noted that the values computed as standard according to international norms are valid within a range of 20% of the standard values established herein. These standard values vary according to age and weight, and become less and less valid with advanced age, especially with respect to carbon dioxide tests.
Test of ventilatory function may be supplemented with a Jones type progressive effort test.
As it is impossible to evaluate respiratory impairment to within 1%, the impairment will be nil or 5% and over.
Classes of respiratory impairment
i
.
Class I
Roentgenograms of the chest are usually normal, but there may be evidence of healed or inactive disease of the chest, such as minimal nodular silicosis or pleural scars. Dyspnea, where it occurs, is consistent with the circumstances of activity. Values obtained from tests of ventilatory function are not less than 85% of predicted normal values for the patient’s age, sex, and height: – 0%
ii
.
Class II
Roentgenograms of the chest may be normal or abnormal. Dyspnea does not occur at rest and seldom occurs during the performance of the activities of daily living. The patient can keep pace with persons of the same age and body build on a level surface without breathlessness but not on hills or stairs. Values obtained from tests of ventilatory function are in the range of 70% to 85% of the predicted normal values for the patient’s age, sex, and height: – 10 to 20%
iii
.
Class III
Roentgenograms of the chest may be normal but usually are not. Dyspnea does not occur at rest but does occur during the performance of the activities of daily living. However, the patient can walk 2 kilometres (1 mile) at his own pace without experiencing dyspnea, although he cannot keep pace on a level surface with others of the same age and body build. Values obtained from tests of ventilatory function are in the range of 55% to 70% of the predicted normal values for the patient’s age, sex, and height. The test of arterial oxygen saturation when performed at rest and after exercise, is usually 88% or greater: – 25 to 35%
iv
.
Class IV
Roentgenograms of the chest are usually abnormal. Dyspnea occurs during such activities as climbing one flight of stairs or walking 100 m over a level surface, with a minimum of exertion, or even at rest. Values obtained from tests of ventilatory function are less than 55% of predicted normal values for the patient’s age, sex and height. The test of arterial oxygen saturation, when performed at rest or after exercise, is usually less than 88%: – 50% and over
A ventilatory impairment of 60% and more is equal to an impairment of: – 100%

TITLE VII
CARDIOVASCULAR SYSTEM
Vascular impairment is usually caused by multiple lesions and does not require special evaluation. However, complications resulting from a vascular lesion must be distinguished from symptoms originating in the nervous or musculoskeletal system. The vascular diagnosis must be based on objective clinical findings or specific recognized vascular tests.
In order to establish a relationship between an accident and a cardiovascular abnormality
(
a
)
the vascular lesion must not have been present before the accident and the presence of the following must be looked for:
i
.
symptoms suggesting a certain degree of vascular insufficiency or other disorder having occurred before the trauma;
ii
.
signs of a disease already recorded in previous examination reports;
iii
.
chronic vascular insufficiency or other disease in an untraumatized extremity.
However, it must be borne in mind that the trauma may have worsened a preexisting disease which probably would have remained asymptomatic for a long period of time.
(
b
)
the lesion must have developed within a reasonable period of time after the trauma, that is, in less than 15 days in particular instances and with justification, that period may be extended to 90 days.
(
c
)
the trauma must show sufficient signs of localization and severity.
(
A
)
MAJOR CARDIOVASCULAR LESIONS
Major cardiovascular lesions must be evaluated individually taking into account the severity of the lesion and possible future consequences in cases where there are no immediate sequelae.
The following lesions are type cases which must be evaluated by a specialist in cardiovascular and thoracic surgery
(
a
)
cardiac and pericardial lesions
(
b
)
major lesions of arterial and veinous trunks: thoracic and abdominal aorta, pulmonary artery, arteries off the aortic arch, superior and inferior vena cava

TITLE IX
PSYCHIC SYSTEM
INTRODUCTION
The psychic functions (mental, affective, adaptive, behavioural) of certain accident victims may be permanently damaged
(
a
)
General Impairment Producing Mechanisms
Such impairments are sometimes the direct consequence of a lesion in the central nervous system and therefore entail a psychiatric or psychological evaluation which goes beyond the sole assessment of a neurological impairment. In other cases, the impairment reflects a permanent affective dysfunction revealing chronic psychological maladaptation to trauma having temporarily or permanently damaged another part of the body. Impairments of this nature may sometimes result from the interaction of the 2 impairment producing mechanisms.
(
b
)
General Evaluation Criteria
Impairment is assessed by means of a clinical psychiatric or psychological examination. Adequate knowledge of the accident victim’s personality prior to the accident, his complete background and his usual mode of adaptation is necessary for the conducting of a clinical evaluation. The victim’s premorbid level of personal adaptation must be considered in order to determine the degree of functional damage stemming from mental illness caused by an accident.
A detailed objective mental examination is essential. The symptomatology must establish an entirely credible, total and coherent syndrome. Impairment of psychic functions must be manifested by changes in the patient’s daily activities and interpersonal relationships and in certain cases must be accompanied by physiopathological signs. Symptoms must be present during a sufficiently long period and, as a rule, must persist despite constant, standard therapy Additional objective information on the patient’s abnormal mental condition is usually provided by his family and friends and those treating him. A purely subjective syndrome that is difficult to verify rarely indicates severe permanent partial impairment.
The clinical evaluation may sometimes be supplemented with a social or psychometric evaluation. Unfavourable social circumstances may influence that accident victim’s rehabilitation and overall prognosis but do not in themselves constitute an impairment of psychic functions. The evaluation must take his motivational aspect into account. Lastly, an impairment assessed by such psychiatric or psychological evaluation is different in its very nature from an impairment caused by the loss of enjoyment of life or of a mutilated organ.
(
c
)
Groups and Classes of Impairment
Permanent impairment of the accident victim’s psychic functions may result from
— chronic brain syndromes
— psychoses
— neuroses
— personality disorders
The history of psychiatric or psychological sequelae, the specific results of the mental examination and supplementary examinations usually allow only one nosologic category to be determined. However, organic brain syndromes may, in particular, be accompanied by and thus include in their clinical picture and evaluation psychotic or neurotic signs or deterioration of the personality.
Symptomatic severity is accompanied by repercussions going beyond the accident victim’s mere experience to change his usual activities of daily living and his personal or social efficiency. The accident victim requires constant supervision or therapy, assistance or a particular milieu, and in certain cases even needs to be looked after on a full-time basis for the fulfillment of his basic needs.
The diagnosis as to the degree of severity of the impairment affecting the whole person must be specified by applying the general evaluation criteria, by taking the objective effects of the assessed syndrome into consideration, and by referring to the following classes
— Class I: minor impairment: – 0 to 15%
— Class II: serious impairment: – 15 to 45%
— Class III: extremely serious impairment: – 45% and over
Precise quantification in one class may be difficult to achieve, thus the necessity for a comparison with similar cases whose development was followed by the evaluating health professional. It may be necessary to wait some time before the final evaluation of the impairment can be carried out.
A standard clinical psychiatric or psychological evaluation may not necessarily determine an additional impairment and may be useful only for evaluating the motivation of a patient with an impairment in another system or for establishing that the patient’s potential for a more complete rehabilitation requires further scrutiny before the degree of impairment in the other system is established.
(
A
)
CHRONIC BRAIN SYNDROMES
The syndrome is directly associated with organic brain injury resulting from trauma. Above all, it consists of disturbances of the higher cognitive functions. It is essentially characterized by impairment of orientation, comprehension, memory and of the abilities to learn, anticipate, make decisions and exercise judgment. A supplementary psychometric evaluation may be useful in this case. In addition to these essential signs, the subject may show signs of instability, puerilism, erosion of the importance of moral values, or character disorders.
The syndrome is sometimes complicated by psychotic or neurotic reactions in which case they are included in the evaluation. Psychoses or neuroses without organic brain injury will be evaluated separately in their own class.
(
a
)
Class I
The patient has impairment of the higher cognitive functions but is able to perform most of the activities of daily living, as prior to the accident: – 0 to 15%
(
b
)
Class II
The patient has impairment of the higher cognitive functions and in some cases exhibits constant or intermittent but recurring psychotic or neurotic symptoms, to such an extent that he requires supervision and direction for several or most of his daily activities: – 15 to 45%
(
c
)
Class III
The impairment of the higher cognitive functions and the psychological adaptation to the impairment itself are such that the performance of daily activities requires more or less constant care in a protective milieu (home or similar establishment).
Patients with extremely severe impairments require help even in meeting their most elementary needs: – 45% and over
(
B
)
PSYCHOSES
Psychosis is a severe disturbance of mental function likely to cause more or less considerable impairment, depending on its nature, severity, duration, repercussions, the patient’s history and his reaction to therapeutic measures. It is often advisable to wait 2 or 3 years before making the final evaluation of the impairment. The clinical picture may then stabilize and show evidence of permanent impairment. In certain cases basic impairment may be only the more or less strong possibility of relapses.
The syndrome is essentially manifested by disturbances in perception, thinking (process, form, content) and behaviour and by abnormalities in emotional control. It is usually accompanied by a lack of self-criticism and often involves abnormal behaviour discernible by those around him.
(
a
)
Class I
An impairment in this Class is manifested by minor and discrete disturbances in perception, thinking, emotional control or behaviour, but it has little effect on how the patient functions in comparison to his adaptation prior to the accident. Patients who are well controlled by constant psychotropic medication, which alleviates the necessity for rehospitalization, are placed in this Class: – 0 to 15%
(
b
)
Class II
A psychosis in this Class is evident upon mental examination, easily discernible by those around the patient and is reflected in difficulty in social behaviour, odd behaviour and a fairly noticeable reduction in social and personal efficiency. Nevertheless, disorders are not too serious, so the patient can be tolerated in his milieu. The patient’s collaboration is inconstant, the possibility of intermittent hospitalization is likely and the syndrome is poorly controlled by medication. The patient may require occasional supervision and direction in leading his daily life: – 15 to 45%
(
c
)
Class III
A psychosis in this Class is so severe that the patient manifests disturbances in perception and thinking, and an inability to control his emotions that leads him to behave in a way that is socially intolerable or dangerous to his own well-being. The patient always requires at least part-time supervision and direction so that he can lead his daily life. In more serious cases, he may require a protective milieu or constant care in an establishment, with recurrent hospitalization: – 45% and over
(
C
)
NEUROSES
Individuals react differently to life’s problems. Some accident victim’s are prone to adapt neurotically to trauma and its sequelae. Neuroses have no known organic cause. The patient remains lucid and is able to distinguish between external reality and his own subjective experiences. He does not show personality disorganization, but his behaviour may be disturbed within the limits of what is generally socially acceptable. Neuroses may entail excessive anxiety and phobic, hysterical, obsessive-compulsive, depressive and sometimes even psychosomatic symptoms.
Given the strictly subjective nature of a neurosis, its great variability, its natural tendency to subside and the motivational context (secondary gains), it is necessary to wait long enough to ensure a strict application of the following general clinical evaluation criteria: previous manner of adaptation, objective repercussions on daily life and relationships, the psychosomatic element, regular continuation of treatment, and social context.
(
a
)
Class I
i
.
The neurosis is above all subjective but credible, complete and coherent. It is attended with minor changes and does not render the victim incapable of adaptive behaviour. There is no reduction in daily activities or in social or personal efficiency: – 0 to 15%
ii
.
As these impairments do not result from a severe disability, they usually should be placed in the lowest third of this percentage, specifically, from: – 0 to 5%
(
b
)
Class II
The symptomatic severity of the neurosis, although usually variable, requires the patient to constantly rely on alleviating therapeutic measures and to modify his daily activities, therefore substantially reducing his social and personal efficiency. The neurosis may also entail functional psychophysiological disorders requiring symptomatic treatment and causing intermittent stoppage of regular activities: – 15 to 45%
(
c
)
Class III
i
.
The neurosis is overpowering and leads to a definite deterioration of personal and social efficiency. Interpersonal relationships undergo considerable and constant changes – isolation or the need of being encouraged and comforted. Daily activities are upset, and the patient needs to be supervised and guided by those around him. Pathological tissular lesions which are more or less reversible may be present with the psychosomatic component: – 45% and over
ii
.
It is uncommon for a neurotic condition alone to be attended with regression, deterioration and dependence justifying a percentage higher than the lowest third of this percentage; the impairment should be between: – 45 to 65%
(
D
)
PERSONALITY DISORDERS
This class mainly concerns character disorders attended with a lack of emotional maturity and expressed as difficulty in interpersonal relationships, poor control of inhibitions, a reduction of tolerance to frustration, excessive egocentricity, inconstancy of efficiency, and fairly serious social maladaptation. In most cases, manifestations of personality disorders existed prior to the accident, and impairment, if any, only increases the preexisting social maladaptation. The motivational context with respect to temporary demonstrative reactions that are likely to subside after the financially advantageous settlement of the impairment granted must be assessed carefully. A social evaluation in addition to the clinical evaluation may prove useful.
Personality changes caused by organic brain syndrome must be evaluated in accordance with the Scale provided therefor.
(
a
)
Class I
i
.
The level of character adjustment usually existing prior to the accident is consistently worsened and leads to a more pronounced deficiency in social judgment, deterioration of interpersonal relationships, increasing variability inconsistency in efficiency, behavioural deviations and the inability to avoid coming into conflict with society or harming oneself. The patient is not capable of adapting to the difficulties of daily life: – 0 to 15%
ii
.
In general, the impairment should not exceed the lowest third of this percentage: – 0 to 5%
(
b
)
Class II
The maladaptation is such that the individual shows considerable loss of self-control, is not able to learn from experience and seriously harms himself and those around him in a repeated manner. The lack of social control may have resulted in legal supervision of various kinds. Such psychiatric or psychological impairment, when considered separately, is rarely granted. It must be determined whether or not such objective behavioural deterioration belongs to another impairment class: – 15 to 45%
(
c
)
Class III
Does not apply in this category: – 45% and over
