The study analyzed the experience of the Los Angeles Count? Department of M
ental Health with implementation of new contractual arrangements for servic
es for patients with severe mental illness. The arrangements shifted the fi
nancial risk for treatment to community organizations and paid a fixed annu
al rate per enrolled patient without further adjustment for severity of ill
ness. Patients were assigned to the program based on high prior treatment c
osts. The new contractual approach enhanced programs' flexibility and accou
ntability and increased their emphasis on principles of psychosocial rehabi
litation. Challenges in implementation included disenrollment of the majori
ty of assigned patients by the community organizations at risk for high tre
atment costs. Prior treatment costs for continuing cases, while high, were
lower than those for disenrolled cases. Existing information systems provid
ed limited clinical and cost data, making it difficult to monitor providers
' performance. Risk contracting required substantial clinical, fiscal, and
management changes at community organizations and the mental health authori
ty. The analysis suggests that mental health authorities that are planning
to institute risk contracts need to balance fiscal incentives with performa
nce guarantees and to pall particular attention to information systems requ
irements and to the severity. of patients illness. Although risk contracts
present challenges, the, can lead to implements in service delivery that pe
rsist beyond the implementation phase.
