One of the biggest areas of concern is lack of facilities and also specifically with regards to children, the problem whereby children fall through the cracks of the system as they become adults.
As for research I will draw your attention to the
federal statute passed a few months ago. Building on that I would say that care techniques are important, because the use of technology can allieviate some of the lack of capacity issues as well as was to create and broader management of the illness to ensure they receive on-going treatment even as they mature into adults. The problem of lack of facilities will remain to some extent as there are some patients that just cannot be treated out-patient or through therapy done via a two way video chat, known as teletherapy. The cost thought is rather high, and we have basically operated over the past sixty years as if everyone can be dealth with out-patient. In some case, 80% and even 90% reductions in capacity have occured compared to the 1950's and the population has grown significantly since then.
And causation is a critical area that needs all the research it can get. As for cost, I wouldn't be able to say as that would have to depend on the amount of available funds in the regional budget and we basically avoided the issue in the Senate by redirecting existing funding to the state priorities.
