Use of neuroleptics in a general hospital.
BACKGROUND
This study investigates the clinical use of neuroleptics within a general hospital in acutely ill medical or surgical patients and its relation with dementia three months after admission compared with control subjects.


METHODS
Cases were defined as every adult patient to whom a neuroleptic medication was prescribed during their hospitalization in our Hospital from February 1st, to June 30th, 1998. A control matched by age and sex was randomly selected among patients who had been admitted in the same period, in the same department, and had not received neuroleptics drugs (205 cases and 200 controls). Demographic, clinical and complementary data were compared between cases and controls. Crude odds ratios estimating the risk of dementia in non previously demented subjects compared with the risk in non-demented control subjects were calculated.


RESULTS
205 of 2665 patients (7.7%) received a neuroleptic drug. The mean age was 80.0 +/- 13.6 years and 52% were females. They were older and stayed longer than the rest of the population. Only 11% received a psychological evaluation before the prescription. Fifty two percent were agitated while 40% had no reason justifying the use of neuroleptic drug. Three months after neuroleptic use 27% of the surviving cases and 2.6% of the surviving controls who were judged non-demented at admission were identified as demented.


CONCLUSIONS
The most common reason for neuroleptic treatment was to manage agitation symptomatically in hospitalised patients. Organic mental syndromes were rarely investigated, and mental status exams were generally absent. Most of neuroleptic recipients had either recognised or unrecognised dementia.
