PURPOSE
To construct a situation-specific theory (SST) to represent nutritional deficits for assessing children with cancer.
DATA SOURCES
Literature review.
DATA SYNTHESIS
The SST included the definition of key concepts, a pictorial scheme, propositions, causal relationships, and evidence for nursing practice.
CONCLUSIONS
It was possible to characterize the elements as antecedent and consequent clinical factors to allow for an understanding of the existing relationships between them and their temporality. These elements differed considerably from those included in NANDA International.
IMPLICATIONS FOR NURSING PRACTICE
This study provides additional information so that nurses in clinical practice can infer the presence of nutritional deficits in children with cancer early, given the risk already inherent in the diagnosis of cancer and treatment.
目的
构建一个特定情境理论（SST）来表示癌症儿童的营养不足，以进行评估。
资料来源
文献回顾。
资料综合
SST 包括关键概念的定义、图示方案、命题、因果关系以及护理实践的证据。
结论
可以将这些元素描述为临床前因和后果因素，以理解它们之间现有的关系及其时间性。这些元素与 NANDA International 中包含的元素有很大的不同。
对护理实践的意义
本研究提供了更多的信息，以便临床实践中的护士能够根据癌症诊断和治疗中固有的风险，尽早推断出癌症儿童存在营养不足的情况。
