本文通过系统检索中国国家知识基础设施、万方数据知识服务平台、中国生物医学文献数据库、中文科技期刊数据 库、Pubmed、Embase、Web of Science、CINAHL 数据库中与营养影响症状相关的文献分析及阐述营养影响症状的定义及其内 涵,检索时限为建库至 2024 年 4 月。 应用 Walker 和 Avant 概念分析法对肿瘤患者营养影响症状的定义属性、前置因素、后置 影响等方面进行分析和整合,共有 32 篇文献符合标准。 营养影响症状定义属性为多维度性、持续存在、动态变化和累加负担; 前置因素包括患者因素、疾病因素、支持因素;后置影响包括营养不良风险增加、生活质量下降、不良的临床结局、经济负担加 重。 肿瘤患者营养影响症状表现为一个复杂的综合过程,受个体及外环境等多方面影响,对患者的临床结局产生负面影 响,护理中应采取多维度干预方式早期识别营养风险,为改善营养影响症状发挥积极作用。

This article systematically retrieves the literature related to nutritional impact symptoms from China National Knowledge Infrastructure CNKI Wanfang Database Chinese Biomedical Literature Database VIP Database Pubmed Embase Web of Science and CINAHL database analyzes and elaborates on the definition and connotation of nutritional impact symptoms. The search period is from the establishment of the database to April 2024. The Walker and Avant conceptual analysis methods were applied to analyze and integrate the definition attributes predisposing factors and aftereffects of symptoms affected by nutrition in tumor patients. A total of 32 literatures met the criteria. The definition attributes of symptoms affected by nutrition are multi-dimensional persistent dynamically changing and cumulative burden. The predisposing factors include patient factors disease factors and supporting factors The aftereffects include an increased risk of malnutrition a decline in quality of life adverse clinical outcomes and an increased economic burden. The symptoms of nutritional impact in cancer patients manifest as a complex and comprehensive process influenced by multiple aspects such as the individual and the external environment which has a negative impact on the clinical outcomes of the patients. In nursing a multi-dimensional intervention approach should be adopted to identify nutritional risks at an early stage and play an active role in improving the symptoms of nutritional impact.
