Abstract

PURPOSE
The purpose of this study was to compare long-term hospital and general hospital for delirium prevalence and precipitating factors in elderly patients. METHOD: The participants were 184 patients aged 65 or older from one general hospital and 4 long-term facilities. Delirium was assessed using the Confusion Assessment Method and precipitating factors for delirium were classified as demographic, physical condition, disease and drug factors associated with delirium found in a literature analysis.
RESULTS
Delirium prevalence was 5.4% and there was no significant difference according to hospital type. Most of the patients with delirium were male, dependent and dehydrated and had sleep disturbances, diseases and drugs associated with delirium and, had multi-drugs prescriptions. Non-delirious patients also had two or more delirious symptoms and several precipitating factors. Delirious patients were more dependent, urinary incontinent and had sleep-disturbances compared to the non-delirious group. The participants in the long-term hospitals were found to have frequently previous delirium history.
CONCLUSION
Even though the prevalence rate of delirium was not high, most elderly patients, regardless of delirium, are a very high risk group and dependent ADL, sleep disturbances, and/or urinary incontinence could be used predictive factors for delirium.
