In Eugene, OR, where I live, there is a program called CAHOOTS ("Crisis Assistance Helping Out On The Streets") which is more or less the mental health equivalent of an ambulance. They're dispatched by non-emergency operators to situations such as mental health crises, public intoxication, and welfare checks- things where police officers would be asked to serve as a social worker, as the article puts it.
My understanding is that the program has been quite successful, and other cities have begun implementing their own similar programs using it as a model.
