The health authorities across the country have different scopes and responsibilities. Some have a lot more than others. We can't forget that in the United Kingdom there is an actual health service organization. We have payment systems that allow us to access health services. We have doctors who can work independently. We have hospitals where you find nurses, and so on, but we don't actually have systems that are integrated, and that's a really big difference.
The optimistic view of health authorities, say, 40 years ago was that they would become the locus of management for this range of questions. But I think if you look across the country, sometimes they have a lot of scope and other times they don't. Sometimes they are responsible for, say, just the hospital and long-term care budgets, but they might not even have public health. Then somewhere else there are community care access centres, and somewhere there's housing, but they don't have all of them together.
