PREVALENCE AND RECOGNITION RATES OF PSYCHIATRIC DISORDER IN THE ELDERLY CLIENTS OF A COMMUNITY CARE SERVICE.

One hundred and sixty-nine people over the age of 65 receiving home care services in Lewisham were interviewed using the Geriatric Mental State (A) (GMS(A)) and diagnostic output was obtained using AGECAT. The prevalence of psychiatric disorder in this group is reported and is compared with that found in community surveys which have used the GMS/AGECAT package. Of note is the 26.0% prevalence rate of cases of depression. The prevalence rate of AGECAT ‘depressive psychosis’ was found to be 13.6%, which was significantly higher than expected. Measures of agreement between AGECAT diagnostic cases and assessments made by home care staff are presented—‘kappa’ values and negative predictive values are higher for organic cases than for cases of depression. These ‘recognition’ rates are compared with reported recognition rates of psychiatric disorder in the elderly by health care professionals. Suggestions for further research are made so that the stated alms of the White Paper Caring for People can be achieved. [ABSTRACT FROM AUTHOR]
