Background: Informal carers often play an integral role in the lives of people with intellectual disability (ID) residing in the community. In this study, we explored the extent to which carers of people with ID believe that the health care needs of the person they care for are being accommodated by general practice. Method: Semi-structured interviews were conducted with 25 informal carers to people with ID living in Australia. Results: Carers of people with ID report that they experience considerable barriers to accessing general practice care on behalf of the people they care for. Conclusions: Given the ever-increasing number of people with ID now living in the community and their vulnerability to health problems, it is imperative that future research focuses on the development of strategies to overcome the barriers identified in this study.
