Expansion of the consultation-liaison psychiatry paradigm at a university medical center: integration of diversified clinical and funding models. 
The perspective of the contemporary Consultation-Liason Service (CLS) psychiatrist is increasingly one of consultant to medical and surgical colleagues in models other than inpatient medical and surgical units.  Simultaneously, the need for a clinically and educationally robust inpatient CLS persists despite funding pressures.  The University of California, Davis Medical Center Department of Psychiatry has made use of creative organizational and financial models to accomplish the inpatient CLS clinical and educational missions in a fiscally responsible manner.  In addition, the department has in recent years expanded the delivery of psychiatry consultation-liaison clinical and educational services to other models of care delivery, broadening the role and influence of the CLS.  Several of the initiatives described in this paper parallel an overall evolution of the practice of consultation-liaison psychiatry in response to managed care influences and other systems pressures.  This consultation-liaison paradigm expansion with diversified sources of funding support facilitates the development of consultation-liaison psychiatry along additional clinical, administrative, research, and educational dimensions.  Other university medical centers may consider adaptation of some of the initiatives described here to their institutions.
