Abstract:
OBJECTIVES: Delirium is a disorder defined as a sudden disturbance in thinking, speaking, acting and sleep pattern due to altered level of consciousness and cognitive function. The objective of this study is to analyze characteristics and therapeutic methods of the delirious patients during the recent 5 years, and provide basic data for further studies and investigation regarding delirium in the occurrence and treatment. METHODS: We retrospectively reviewed medical records of 475 patients who were consulted for delirium in Kyunghee University Medical Center from January 2007 to December 2011. RESULTS: During the 5 years, among the 475 patients who were diagnosed as delirium, men were more common(61.7%). The most commonly consulted reason and cause were sleep disturbance(80.8%) and post-operational delirium(30.9%), respectively. The medication prescription percentage was 76.6% and was significantly increased year after year. Ratio of using antipsychotics were 76.4% among prescribed medication and the most frequently prescribed antipsychotic drug was quetiapine(46.8%). Other specialists commonly misdiagnosed delirium when the patient was previously diagnosed as dementia(6.8%). CONCLUSIONS: In our study, post-operational delirium was the most commonly referred reason and the percentage of medication prescription tended to increase. Patients with history of dementia were more easily misdiagnosed as diseases other than delirium. Our study suggests that we should evaluate symptoms, causes, reasons of consultation, management tendency of delirium. We should also closely observe changes in sleep patterns and establish the prevention strategies for post-operational delirium and therapeutic bases for pharmacotherapy.
