The Confusion Assessment Method (CAM) is a simple screening tool for delirium used worldwide. We made the CAM Japanese version and validated usefulness for 53 cases, which became orthopedics hospitalization by femoral neck fracture from January 1, 2012 to July 31. Twelve patients (22.6%) met the criteria for delirium. The CAM positivity was 11 subjects (10 delirium, 1 non-delirium), and the CAM negativity was 42 subjects (2 delirium, 40 non-delirium). It seemed that CAM Japanese version had a sensitivity of 83.3%, specificity of 97.6%, Cohen's kappa coefficient of 0.83, and Phi value of 0.78. We considered the CAM Japanese version to be a useful screening tool for delirium.
