Abstract

Background: Postoperative delirium (POD) is a transient postoperative complication that occurs after surgical procedures. Risk factors reported for POD include dementia and cognitive decline. The purpose of this study was to identify predictors of POD by examining the use of preoperative neuropsychological tests, including the Mie Constructional Apraxia Scale (MCAS), and patient background factors.

Method: The study was performed as a retrospective cohort study. The subjects were 33 patients (mean age, 75.8 ± 10.9 years; male:female ratio, 26:7) who underwent gastrointestinal surgery at Matsusaka City Hospital between December 2019 and April 2021. Data were collected retrospectively from medical records. The study was started after receiving approval from the institution's ethics committee. The survey items included general patient information, nutritional assessment, surgical information, and neuropsychological tests. Subjects were classified into 2 groups according to the presence or absence of POD. If a significant difference was observed between the 2 groups, the sensitivity, specificity, and area under the curve were calculated using a receiver operating characteristic (ROC) curve.

Result: There were 10 patients in the POD group (male:female ratio, 6:4) and 23 patients in the non-POD group (20:3). The POD group had a shorter education history (p = 0.047) and significantly higher MCAS scores (p = 0.007) than the non-POD group. The ROC curve showed a sensitivity of 90%, a specificity of 69%, and an area under the curve of 0.798 when the MCAS cutoff value was set at 3 points.

Conclusion: Preoperative MCAS results were capable of predicting the occurrence of POD after gastrointestinal surgery. In addition, a relatively short education background was also considered a risk factor for POD.

用Mie构念失用量表预测胃肠手术后谵妄。
背景:术后谵妄(POD)是手术后一过性并发症。据报道,POD的危险因素包括痴呆和认知能力下降。本研究的目的是通过检查术前神经心理测试的使用,包括Mie构念失用量表(MCAS)和患者背景因素,来确定POD的预测因素。方法:采用回顾性队列研究。研究对象33例,平均年龄75.8±10.9岁;男女比例为26:7),他们于2019年12月至2021年4月在松坂市医院接受了胃肠手术。资料回顾性收集自医疗记录。这项研究是在获得该机构伦理委员会的批准后开始的。调查项目包括患者一般信息、营养评估、手术信息和神经心理测试。根据有无POD分为两组。如果观察到两组之间存在显著差异,则使用受试者工作特征(ROC)曲线计算敏感性、特异性和曲线下面积。结果:POD组10例(男女比例为6:4),非POD组23例(男女比例为20:3)。POD组受教育历史较短(p = 0.047), MCAS评分显著高于非POD组(p = 0.007)。当MCAS截止值设为3点时,ROC曲线的灵敏度为90%,特异性为69%,曲线下面积为0.798。结论:术前MCAS结果可预测胃肠手术后POD的发生。此外,相对较短的教育背景也被认为是POD的危险因素。
