This edition of our monthly Series explores ways to make optimal use of available resources to help fill the extensive gaps in behavioral health care (BH) that exist in the US.  We work primarily in the Medicaid arena.  Every BH data analysis task we conduct, every research paper in this area that gets published, and every piece of anecdotal input from persons working on the front lines – all point to the magnitude of the current shortfall among Medicaid enrollees.
