The Office of Mental Health, in conjunction with its local mental health centers acting as the preadmission facilities, must develop and maintain a preadmission screening and evaluation service for all psychiatric emergencies at the local community level utilizing available local resources for mentally ill persons. The preadmission screening services must act as the public mental health system's entry point in order (1) to provide to the examining physician information about accessible crisis intervention, evaluation, and referral services in the community; (2) to offer to mentally ill persons clinically appropriate alternatives to inpatient care, if any; and when necessary (3) to provide a means for involuntary commitment.
