THE REDUCTION IN REFERRALS TO THE LEWIS LEVELY STATE HOSPITAL (LSH) SINCE THE OPENING OF THE CENTER COUPLED WITH THE CASELOAD SIZE OF SIGNIFICANTLY GREATER PROPORTIONS THAN SERVED BY LSH PRIOR TO THE CENTER'S OPENING SHOW THAT THE COURT DIAGNOSTIC AND TREATMENT CENTER IS SUPPLEMENTING THE EVALUATION AND TREATMENT SERVICES OF LSH, LIGHTENING LSH'S CASELOAD, AND PREVENTING THE INSTITUTIONALIZATION OF SOME INDIVIDUALS AND THE RESULTANT NEGATIVE EFFECTS. COST-EFFECTIVENESS ANALYSES DEMONSTRATED THAT THE CDTC NEGATES A SIZABLE PROPORTION OF COSTS INCUMBENT UPON INSTITUTIONALIZATION AT LSH, AND FOLLOW-UP STUDIES INDICATED THAT THE CENTER'S RECIDIVISM RATES ARE BOTH LOWER AND LESS FREQUENTLY A MOVE TO A MORE SERIOUS OFFENSE. THE CENTER IS PERFORMING COMPETENCY/SANITY EVALUATIONS IN A SIGNIFICANTLY SHORTER SPAN OF TIME THAN THAT TYPICAL OF LSH, AND THE PERIOD BETWEEN CENTER RELEASE AND COURT DISPOSITION IS ALSO MUCH SHORTER.
