Objective cognitive assessments, a gold standard diagnostic tool for cognitive impairment, may not be feasible in busy liver transplantation (LT) practice because they are often time consuming. This study determined whether subjective cognition, patients’ self-ratings and/or caregivers’ ratings of patients’ cognition, reflects objective cognition in LT recipients. A convenience sample of 60 adult LT recipients and their caregivers, recruited at a single transplant center, participated in this cross-sectional descriptive study. Subjective cognition (ie, recipient self-rated and caregiver rated) was measured using the Everyday Cognition (ECog; global and 6 domain scores). Objective global and domain-specific cognition of recipients was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Trail Making Test parts A and B, Digit Span Backward, and Rey-Osterrieth Complex Figure. Agreement between LT recipients’ ECog scores and those of their caregivers was fair to moderate (intraclass correlation coefficient = 0.48 for global score, 0.35-0.56 for domain scores). Significant, albeit rather weak, correlations were found between subjective and objective scores. Recipients’ ECog visuospatial abilities scores were correlated with Rey-Osterrieth Complex Figure scores (r_s = −0.39; P = 0.007), whereas caregivers’ ECog global, attention, visuospatial abilities, and organization scores were, respectively, correlated with the scores of RBANS global (r_s = −0.33; P = 0.04) and attention (r_s = −0.46; P = 0.005), Rey-Osterrieth Complex Figure (Copy; r_s = −0.34; P = 0.03), and Trail Making Test part A (r_s = 0.31; P = 0.049). The findings suggest that caregivers may estimate LT recipients’ cognition better than recipients themselves. Caregivers may provide supplemental information that could be useful for clinicians when considering the cognitive functioning of LT recipients.

护理人员报告的主观认知与肝移植受者的客观认知相关

客观认知评估是认知障碍的黄金标准诊断工具，在繁忙的肝移植 (LT) 实践中可能不可行，因为它们通常很耗时。本研究确定了主观认知、患者的自我评价和/或护理人员对患者认知的评价是否反映了 LT 接受者的客观认知。在一个移植中心招募的 60 名成年 LT 接受者及其护理人员的便利样本参与了这项横断面描述性研究。主观认知（即接受者自我评价和照顾者评价）是使用日常认知（ECog；全球和 6 个领域分数）测量的。使用神经心理状态评估的可重复电池 (RBANS) 测量接受者的客观全局和特定领域认知，Trail Making 测试 A 和 B 部分、向后的数字跨度和 Rey-Osterrieth 复杂图形。LT 接受者的 ECog 分数与其看护者的分数之间的一致性是公平到适度的（组内相关系数 = 0.48 为全局分数，0.35-0.56 为领域分数）。在主观和客观分数之间发现了显着但相当微弱的相关性。接受者的 ECog 视觉空间能力得分与 Rey-Osterrieth Complex Figure 得分相关（rs = _−0.39  ；P  = 0.007)，而看护者的 ECog 全局、注意力、视觉空间能力和组织得分分别与 RBANS 全局得分 ( rs  = −0.33；_P =  0.04) 和注意力 ( rs  = −0.46 _；P  = 0.005）、Rey-Osterrieth 复杂图形（复制；r _s  = −0.34；P  = 0.03）和试车测试 A 部分（r _s  = 0.31；P = 0.049）。研究结果表明，看护者可能比接受者自己更好地估计 LT 接受者的认知。在考虑 LT 接受者的认知功能时，护理人员可以提供可能对临床医生有用的补充信息。
