In 2007 the Australian Commonwealth Government announced the Medicare Health Assessment for People with an Intellectual Disability as part of the Enhanced Primary Care (EPC) program (Department of Health and Ageing, 2008). The annual health assessment is a structured framework for general practitioners (GPs), which enables an annual comprehensive assessment of the physical, psychological, and social function of patients with ID, and the identification of any medical intervention and preventative health care that may be required (Department of Health and Ageing, 2008). The health assessment items carry with them significant financial incentives designed to encourage GPs to enhance the quality of detection and management of health concerns of people with ID. In May 2010, however, health assessment items for different groups, including people with ID, were combined into four time-based items (Department of Health and Ageing, 2010b). This change prevents the tracking of item usage as a means of determining the frequency with which individuals with ID receive annual health assessments. This paper reports trends in uptake of ID health assessment items while the data could be differentiated. (Contains 3 tables.)
