The development of an Australian national classification system for social work practice in health care.

Australian Social Work, over recent years, has been challenged to develop a standardised and accurate classification system for social work interventions. The need for such a system arose through changes in funding arrangements based on the Diagnosis Related Groups (DRGs) treated within hospitals. In Australian hospitals, the mix of DRGs treated became known as its 'casemix.' These new funding arrangements made it necessary for Social Work to classify and measure activity with each patient to ensure continuing resource allocation to social work services in hospitals. A national Casemix Network was formed under the auspice of the Australian Association of Social Workers to develop a classification system. The Network worked collaboratively with other allied health professions to produce a generic framework for professional activities and also developed a classification of social work interventions. These activity classifications have been incorporated into procedure coding in Australian hospitals. The challenges associated with casemix funding required Social Work to address a number of philosophical and methodological issues related to classification of professional activities to ensure an outcome that recognised the unique contribution of Social Work to health care.
