BACKGROUND
Subsyndromal delirium following surgery in older adults is related to increased lengths of hospital stay and increased admissions to long-term care. Impaired nutrition increases risk for delirium, but its relationship to subsyndromal delirium remains unclear.
PURPOSE
This correlational study examined the relationship between nutritional status and subsyndromal delirium in older adults.
METHODS
Assessments for subsyndromal delirium in 53 adults 65 years or older were completed for three consecutive days following joint replacement surgery. Relationships between nutritional status and subsyndromal delirium were analyzed. Level of significance for all tests was set at p ≤ .05.
RESULTS
Participants' scores from the Mini Nutritional Assessment screen were significantly related (p = .05) to subsyndromal delirium severity after accounting for variability posed by age and cognition status.
CONCLUSION
When preoperative risk assessment of older adults indicates nutritional risk, preoperative optimization may improve effectiveness of delirium prevention efforts.
背景
老年人手术后出现亚综合征性谵妄与住院时间延长和长期护理入院率增加有关。营养状况不佳会增加谵妄的风险，但它与亚综合征性谵妄的关系尚不清楚。
目的
本相关性研究旨在探讨老年人营养状况与亚综合征性谵妄之间的关系。
方法
对 53 名 65 岁或以上接受关节置换手术后连续三天进行亚综合征性谵妄评估。分析营养状况与亚综合征性谵妄之间的关系。所有检验的显著性水平均设为 p≤.05。
结果
在考虑年龄和认知状态的变异性后，微型营养评估筛查参与者的评分与亚综合征性谵妄严重程度呈显著相关（p=.05）。
结论
当老年人的术前风险评估表明存在营养风险时，术前优化可能会提高谵妄预防措施的效果。
