Book excerpt: Case Management-what is it and how does it fit in the system of mental health care for severely mentally ill patients? Four popular case management systems, each emerging from a distinct theory of human growth and development, answer these long debated questions. Case Management for Mentally Ill Patientswill prove highly useful to mental health students and practitioners, university educators, and professionals providing hands-on help in obtaining a wide range of services including insurance, housing, rehabilitation, general medical psychiatric care, legal services and entitlements, and employment.
