Purpose: This study was done to develop of the Korean intensive care delirium screening tool (KICDST).
Methods: The KICDST wasdeveloped in 5 steps: Configuration of conceptual frame, development of preliminary tool, pilot study, reliability and validity test,development of final KICDST. Reliability tests were done using degree of agreement between evaluators and internal consistency. For validity tests, CVI (Content Validity Index), ROC (Receiver Operating Characteristics) analysis, known group technique and factoranalysis were used.
Results: In the reliability test, the degree of agreement between evaluators showed .80~1.00 and the internalconsistency was KR-20=.84. The CVI was .83~1.00. In ROC analysis, the AUC (Area Under the ROC Curve) was .98. Assessmentscore was 4 points. The values for sensitivity, specificity, correct classification rate, positive predictive value, and negative predictivevalue were found to be 95.0%, 93.7%, 94.4%, 95.0% and 93.7%, respectively. In the known group technique, the average deliriumscreening tool score of the non-delirium group was 1.25±0.99 while that of delirium group was 5.07±1.89 (t= - 16.33, p <.001). Thefactors were classified into 3 factors (cognitive change, symptom fluctuation, psychomotor retardation), which explained 67.4% oftotal variance.
Conclusion: Findings show that the KICDST has high sensitivity and specificity. Therefore, this screening tool is recommendedfor early identification of delirium in intensive care patients.
