Abstract:

Objective Using Rodgers’ evolutionary concept analysis to interpret the concept and connotation of subsyndromal delirium. Methods CNKI,Wanfang,VIP,CBM,PubMed,Web of science,CINAHL,Embase and Psyc-INFO were searched from inception to 2021 for relevant articles. 32 articles were recruited finally. The origin of the concept of subsyndromal delirium,its attributes antecedents,preconditions and influencing factors,consequences were analyzed and combined. Results Subsyndromal delirium’s attributes antecedents were composed of 4 aspects,including a mental cognitive disorder,incomplete delirium state,dynamic fluctuation process and easy to be clinically neglected and missed diagnosis. Its prerequisites can be discussed from the internal orientation（personal physical factors,psychological factors） and external causes（environmental factors,drug factors）. After the occurrence of subsyndromal delirium,it will affect the patient’s cognitive level and long-term quality of life,and increase the mortality rate. Conclusion At present,the research is not deep enough for the study of subsyndromal delirium,and its concept and diagnostic criteria have not yet formed. In the future,we should further explore subsyndromal delirium in a deep and multi-dimensional way.

摘要：

目的 运用Rodgers演化概念分析法诠释亚谵妄综合征的概念及内涵。 方法 系统检索中国知网、万方、维普、中国生物医学文献服务系统、PubMed、Web of Science、CINAHL、Embase和PsycINFO数据库,检索时限从建库至2021年5月,最终纳入文献32篇。应用Rodgers概念分析框架,从亚谵妄综合征概念的起源、概念属性、先决条件、影响因素、结局等方面对亚谵妄综合征的相关内容进行分析、整合。 结果 亚谵妄综合征包括一种精神认知疾病、谵妄的不完全状态、动态波动过程、易被临床忽视和漏诊4个概念属性,其先决条件可从内因（个人机体因素、心理因素）和外因（环境因素、药物因素）进行讨论。亚谵妄综合征发生后会影响患者认知水平及远期生活质量,增加患者病死率。 结论 目前,对于亚谵妄综合征的研究还不够深入,其概念及诊断标准仍未形成定论,未来应进一步对亚谵妄综合征进行深层次、多方位的探索。
