Patterns of psychogeriatric referral and attendance at three different settings in Hong Kong

In order to analyze whether the referral system and nature of care exert any effect on the characteristics of patients, subjects aged 60 or above attending three medical centers on the Hong Kong Island between August and December 1990 were studied with respect to their age, sex, and psychiatric diagnosis. Psychiatric diagnoses were made in 98% of subjects at the psychogeriatric assessment service (PAC) (predominantly chronic organic brain syndrome), in 79.6% at the university psychiatric unit (mainly acute psychiatric problems, substance abuse, and deliberate self-harm), and in 20% at the general outpatient clinic (largely sleep and anxiety-related disorders). There was overrepresentation of the very old (above 80) and underutilization of counseling service at PAC. In Hong Kong, the psychogeriatric needs of the very old and of those with minor emotional disturbances associated with aging, retirement, and bereavement deserve reassessment.
