亚综合征谵妄的老年人在关节置换术后发生不良结局的风险与谵妄患者相似。本研究探讨了亚综合征性谵妄和选择的术前危险因素之间的关系，在老年人主要骨科手术。在关节置换术后第1、2和3天完成了对62例65岁或以上成人样本的谵妄评估。分析谵妄症状与以下术前风险因素之间的关系：合并症负担增加、认知功能障碍、跌倒史和术前禁食时间。68%的研究参与者发生术后亚综合征性谵妄。近期跌倒史和较长的术前禁食时间与谵妄症状相关（p ≤ .05）。最近6个月内有福尔斯跌倒史或术前禁食时间较长的老年人在关节置换术后发生谵妄症状的风险较高。
Older adults with subsyndromal delirium have similar risks for adverse outcomes following joint replacement surgery as those who suffer from delirium. This study examined relationships among subsyndromal delirium and select preoperative risk factors in older adults following major orthopaedic surgery. Delirium assessments of a sample of 62 adults age 65 or older were completed on postoperative day 1, 2, and 3 following joint replacement surgery. Data were analyzed for relationships among delirium symptoms and the following preoperative risk factors: increased comorbidity burden, cognitive impairment, fall history, and preoperative fasting time. Postoperative subsyndromal delirium occurred in 68% of study participants. A recent fall history and a longer preoperative fasting time were associated with delirium symptoms (p ≤ .05). Older adults with a recent history of falls within the past 6 months or a longer duration of preoperative fasting time may be at higher risk for delirium symptoms following joint replacement surgery.
