Delirium exacerbates the prognosis of ICU patients but is likely to be overlooked without an appropriate screening being performed. In Japan, however, there exists no verified ICU delirium evaluation method available to the medical staff other than psychiatrists. Therefore, we verified the validity and reliability of the Japanese version of the CAM-ICU Flowsheet at two ICU facilities in Japan. Using the evaluation of the DMS-IV-TR in the psychiatrists group as the standard criteria for delirium diagnosis, we compared the evaluation of the Japanese version of the CAM-ICU Flowsheet between the research nurses group and the staff nurses group. We performed a comparative analysis with 82 patients and found that the prevalence of delirium was 22.0% and the RASS level was ranging from -0.33 to -0.28. As a result, the Japanese version of the CAM-ICU Flowsheet showed the sensitivities of 78% and 78% and the specificities of 95% and 97% to the DSM-IV-TR, respectively. The degree of coincidence between the Japanese versions of the CAM-ICU Flowsheet turned out to be：κ=0.81. Thus, the Japanese version of the CAM-ICU Flowsheet was proven to be available as a tool for the ICU delirium evaluation with validity and inter-rater reliability for surgical ICU patients.
