Historically, state mental health authorities have dominated public me
ntal health services, operating with fixed resources and responsible f
or a large population. A good public mental health system has many of
the attributes of a well-managed private mental health system. Unfortu
nately, public systems are not flexible enough to contract creatively
with multiple providers; they lack many of the tools of modem managed
care. As a consequence, state mental health authorities have begun to
contract with private managed care firms to assist them in managing th
eir health care reform efforts, particularly reform of Medicaid. This
paper examines the forces shaping managed behavioral health care in th
e public sector and describes strategies for managing care, such as co
ntracting, utilization review, and monitoring.
