IGDA. 7: Standardised multi-axial diagnostic formulation
IGDA WORKGROUP, WPA
 |
7.1
|
---|
A thorough and systematic assessment of a patient should lead to a
comprehensive diagnostic statement. The first component of this is the
multi-axial diagnostic formulation.
 |
7.2
|
---|
A multi-axial diagnostic formulation provides a contextual and standardised
description of the clinical condition through a number of highly informative,
therapeutically significant and systematically assessed axes or domains.
 |
7.3
|
---|
A tetra-axial formulation is recommended as follows:
- Axis I: clinical disorders (mental and general medical conditions);
- Axis II: disabilities (in personal care, occupational functioning,
functioning with family, and broader social functioning);
- Axis III: contextual factors (interpersonal and other psychosocial and
environmental problems);
- Axis IV: quality of life (primarily reflecting patient's
self-perceptions).
 |
7.4
|
---|
Axis I (clinical disorders) consists of all relevant psychiatric disorders
(including personality and developmental disorders) and general medical
conditions that are identified on the basis of a comprehensive historical
anamnesis, evaluation of symptoms, mental state examination, supplementary
assessment instruments and the physical examination. Disorders are to be
listed in their order of importance for disposition and care.
 |
7.5
|
---|
Axis II (disabilities) comprises ratings of impairment in important areas
of adaptive functioning. Impairments may be the result of mental disorders,
physical disorders, or both. Included are impairments in four separate areas
of functioning, as follows:
- personal care and survival;
- occupational functioning, including roles as paid or volunteer worker,
student or homemaker;
- family functioning, including interaction with spouse, children, parents
and other relatives;
- broad social functioning, including roles, activities and interactions with
other individuals and groups in the community at large.
Ratings are to be made for each area of functioning, using a
semi-quantitative six-point scale based on frequency and intensity of
impairments (Fig. 7.1). The
scale anchor point descriptions are: 0, none (no identifiable disability); 1,
minimal (disability low in both intensity and frequency); 2, moderate
(disability medium in either intensity or frequency, low in the other); 3,
substantial (disability medium in intensity and frequency); 4, severe
(disability high in intensity or frequency, lower in the other); 5, massive
(disability high in intensity and frequency).

Axis III (contextual factors) consists of all relevant psychosocial and
environmental problems. Such problems may be relevant to the onset,
exacerbation or maintenance of a disorder listed on Axis I, or be in
themselves targets of clinical care. They may be acute events or chronic
circumstances. This axis also includes personal problems that do not amount to
a disorder proper, but are of clinical significance (e.g. accentuated
personality, or hazardous, violent, abusive or suicidal behaviours).
Contextual factors can be coded according to the ICD10 Z-codes (factors
influencing health status and contact with health services).
 |
7.7
|
---|
Axis IV (quality of life) is a multi-dimensional and global assessment of
the patient's self-perceived well-being in areas such as physical and
emotional state; satisfaction with independent, occupational and interpersonal
functioning, and with socio-emotional and instrumental supports; and a sense
of personal and spiritual fulfilment. Its assessment should be culturally
informed. Its appraisal may be based on one of the many standardised
quality-of-life instruments available or on a direct global self-rating using
a scale such as that provided on the proposed diagnostic formulation
(Fig. 7.1).
 |
7.8
|
---|
Domains of the multi-axial formulation should be assessed with sensitivity
to the culture of the patient. The identification and rating of the importance
of significant problems in health, functioning and social context should be
made in relation to pertinent cultural norms and customs.
 |
7.9
|
---|
The completion of a multi-axial assessment is made easier by the
availability of a reprinted record sheet in the patient's clinical chart, in a
format designed to ensure that all the domains of the multi-axial schema are
attended to and systematically appraised. An example of such a completed form
is given in IGDA Workgroup, WPA
(2003b, this suppl.:
Appendix 2).

|
---|
The main purpose of the multi-axial diagnostic formulation is to inform the
preparation of a comprehensive treatment plan (see
IGDA Workgroup, WPA,
2003a, this suppl.). Additionally, it may facilitate and
optimise longitudinal reassessments of the patient's condition and therefore
afford a refinement of the validity of clinical diagnosis. Furthermore, it can
serve as an outcome measure of therapeutic interventions.
