Education, employment and housing services, as noted in previous sections of this book, promote the development of healthy individuals and communities. People with complex needs require support from statutory and third sector health and social service agencies. This section will provide an insight into the needs of people with mental health and cognitive disabilities. These needs are often associated with housing needs and limited access to appropriate health and social care. The multiple complex needs of homeless people include mental health, substance misuse, relational problems and skill deficits. Providing support for these often disengaged people has many challenges due to the problems of lack of collaborative working between the tiers of local government, the National Health Service (NHS) and the third sector. The development of ‘Inclusion Health’ pathways into primary care is an innovative approach, underpinned by an understanding of the psychological dimensions of both those who are homeless and those providing support for the homeless.
