To give the most basic example, there is no formalized charting system in the Mental Health Industry. You have standardized notes that are turned into the county but that's about it.
The industry I work in (treatment of abused children who have been removed from the home) has a 96% fail rate in California. That means 96% of the children entrusted to the state end up in jail or dead by the age of 25 (as of 2003). So if ever there was an industry that needed technology's help it's this one.
