Where treatment and health care is no longer able to bring relief and improve functioning, social care should take over. In this chapter, we discuss the development of social care in the context of adult autism, and the range of its concerns and interests is considered. The key role of the social worker, particularly as a broker of social care, is developed. Health professionals define the need for reasonable adjustments to assessed disability, and the content of a personal passport, summarizing individual’s needs. Health professionals also have a key role in risk management, although the social worker may have a key co-ordinating role. A wide range of contexts for social care within and beyond health care is considered. The distinction between individual need and care planning, and the role of the wider society, which will be covered in Chapter 14, concludes this chapter.
