BACKGROUND
The aim of this paper was to give a critical appraisal of the methodology of nutritional screening and assessment tools.
METHODS
A literature search identified 44 tools. Each tool was assessed in relation to details of its application, method of derivation and evaluation of its performance.
RESULTS
The findings indicate that tools were published with insufficient details regarding their intended use and method of derivation, and with an inadequate assessment of their effectiveness. An appraisal of these features judged that no one tool satisfied a set of criteria regarding scientific merit.
CONCLUSION
There is thus a need to ensure that nutritional screening and assessment tools are developed using procedures based on good design and sound statistical practice. This paper suggests that a unified approach using multivariate techniques could make a significant contribution to this process.
背景
本文旨在对营养筛查与评估工具的方法进行批判性评价。
方法
文献检索确定了44种工具。每种工具都根据其应用细节、推导方法及其性能评估进行了评估。
结果
研究结果表明，工具发表时关于其预期用途和推导方法的细节不足，对其有效性的评估也不充分。对这些特征的评估判断，没有一种工具满足关于科学价值的一套标准。
结论
因此，有必要确保营养筛查与评估工具是使用基于良好设计和合理统计实践的程序开发的。本文建议使用多变量技术的统一方法可以对这一过程做出重大贡献。
