Registration status: | Community Services (retired), Superseded 16/10/2006 |
Definition: | A code set representing the degree of impairment in a specified body function or body structure from the Body Functions and Structures component of the International Classification of Functioning, Disability and Health (ICF 2001). |
Context: | Human functioning and disability. |
Collection and usage attributes | |
Guide for use: | Impairments of body structure or body function are problems in body structure or function such as a loss or significant departure from population standards or averages. Impairments are recorded in terms of their extent or magnitude, nature and/or location. Determination of impairment is undertaken primarily by those qualified to evaluate physical and mental functioning or structure according to these standards. This metadata item contributes to the definition of the concept 'Disability' and gives an indication of the experience of disability for a person. CODE 0 No impairment Is recorded when there is no significant variation from accepted population standards in the biomedical status of the body and its functions [0-4%]. CODE 1 Mild impairment Is recorded when there is a slight or low variation from accepted population standards in the biomedical status of the body and its functions [5-24%]. CODE 2 Moderate impairment Is recorded when there is a medium (significant but not severe) variation from accepted population standards in the biomedical status of the body and its functions [25-49%]. CODE 3 Severe impairment Is recorded when there is an extreme variation from accepted population standards in the biomedical status of the body and its functions [50-95%]. CODE 4 Complete impairment Is recorded when there is a total variation from accepted population standards in the biomedical status of the body and its functions [96-100%]. |

Collection Methods: | This coding is used in conjunction with specified body functions and body structures, for example 'mild impairment of structures related to movement'. This code may also be used in conjunction with Impairment nature code X and Impairment location code X with specified body structures. Broad ranges of percentages are provided for collections where calibrated assessment instruments or other standards are available to quantify the impairment. Many existing assessment tools are in use, and are embedded in measurement and payment methods in services in Australia. Calibration and mapping of existing tools within this international framework will be an important process towards greater national consistency of data on body functions, structures and impairments thereof. Impairments should be detectable or noticeable by others or the person by direct observation or by inference from indirect observation. Impairments are not the same as the underlying pathology, but are manifestations of that pathology. Impairments can be temporary or permanent; progressive, regressive or static; intermittent or continuous. The deviation from the population norm may be slight or severe and may fluctuate over time. Impairments may result in other impairments. Impairments may be part, or an expression of a health condition, but do not necessarily indicate that a disease is present or that the individual should be regarded as sick. |
