The Delirium Rating Scale (DRS) has been shown to be a valid instrument for identifying and grading the severity of delirium in patients admitted to a general hospital for medical or surgical treatment. However, its accuracy in identifying delirium among elderly patients admitted to a psychiatric hospital for evaluation and treatment of psychiatric illness has not been previously addressed. The DRS was administered to 791 elderly patients who were consecutively admitted to a psychogeriatric unit; 70 met DSM-III-R criteria for delirium. A DRS threshold score of > or = 10 correctly identified delirious patients with a sensitivity of 94% and a specificity of 82%. Both psychosis and cognitive impairment appeared to falsely elevate the DRS score in this population.
谵妄评定量表（DRS）已被证明是一种有效的工具，可用于识别综合医院内科或外科治疗的住院患者的谵妄并对其严重程度进行分级。然而，此前尚未探讨过其在识别因精神疾病入院评估和治疗的老年患者谵妄方面的准确性。对连续入住老年精神科病房的791名老年患者进行了DRS评定；其中70名符合DSM-III-R谵妄标准。DRS阈值评分≥10能正确识别谵妄患者，灵敏度为94%，特异度为82%。在该人群中，精神病和认知障碍似乎会错误地提高DRS评分。
