Older patients referred to a consultation-liaison psychiatry clinic

Background. Little is known about the psychiatric disorders which are assoc iated with somatic presentations of psychological distress in older people. Method. A study of patients aged 65 years and over referred to an adult con sultation-liaison psychiatry clinic in a general hospital. Results. Of 900 patients referred over a 7-year period, 45 (5%) were aged 6 5 years and over. The most frequent ICD-10 diagnostic category was somatofo rm disorder (N=30) followed by depressive disorder (N=6). The age of onset of the physical symptoms was significantly earlier in those with somatoform disorders (mean 49 years; SD 3.1 years) compared with patients with depres sive disorders (mean 74 years; SD 3.1 years) (p < 0.05). All diagnoses were equally associated with moderate functional impairment. Conclusion. Medically unexplained physical symptoms may occur as part of a range of psychiatric disorders in order people and diagnostic groups are di stinct in a number of ways. The usefulness of the ICD-IO classification of disorders in relation to these patients is considered. Implications for the delivery of old age psychiatry services are discussed, Copyright (C) 2001 John Wiley & Sons, Ltd.
