한국판 섬망 평가 척도의 표준화 = Standardization of the Korean Version of Delirium Rating Scale

다국어 초록 (Multilingual Abstract)

Objectives : Delirium s a highly prevalent disease that occurs in about 1 5 2 0 % of all general admissions to hospital but there is no standardized rating scale that identifies and assesses the symptom severity for delirium in Korea. The Deliruim Rating Scale (DRS) is a widely used delirium rating instrument that specifically, sensitively, and reliably measures delirium symptoms. This study addresses the reliability and validity of Korean version of Delirium Rating Scale(K-DRS) in Korea.
Methods : 28 patients with delirium, 28 patients with dementia, 27 patients with schizophrenia, and 21 patients with other mental disorder by DSM-IV entered this study All patients received a structured psychopathology assessment including K-DRS Korean version of Mini-Mental Status Examination (MMSE-K) Clinical Global Impression scale(CG1) and in addition schizophrenia group had done Brief Psychiatric Rating Scale (BPRSI Each instrument scores were compared among the four diagnostic groups by one-way analysis of variance with post hoc comparisons to determine where the difference lie K-DRS scores were compared with 'after usual treatment' scores in a subset of delirious subjects Cutoff scores for K-DRS were determined by using receiver-operator Characteristic (ROC) analyses to determine acceptable levels of sensitivity and specificity Inter-subtest Pearson's correlations, Cronbach's alpha coefficient to assess internal consistency and inter-rater reliability were used for the assessment of reliability of K-DRS.
Results : The mean K-DRS score was significantly higher in the delirium group compared with each of the other groups, But mean MMSE-K score was not significantly different between delirium and dementia group Area under curve of K-DRS was 0 998K E=0.002) and its optimal cutoff point for delirium was estimated as 16 5 KDRS score after usual treatment improved from a mean(S.D) of 23 5(3.2) to 3.1(1.7) indicating an ability to measure the severity of delirium K-DRS was found to have significantly high internal consistency(Cronbach's alpha coefficient=0.88) inter-rater reliability (r=0.98 p<0.0001)
Conclusion : We confirmed that K-DRS is a reliable valid, and useful diagnostic instrument for delirium.
