Fall risk assessment is of significant importance in the elderly population as falls constitute a primary cause of injuries and fatalities among the elderly. This paper comprehensively outlines the commonly used algorithms and classification features in fall risk assessment tools constructed using machine learning techniques. By comparing the performance of these models on real-world datasets, it delves into the strengths and weaknesses of various algorithms and their applicable scenarios. The article provides detailed insights into the data prepossessing steps and model construction processes commonly employed in each model, offering a comprehensive comparison. In conclusion, the paper summarizes the current shortcomings in research and anticipates potential directions for future developments in this field.

目的

探讨基于机器学习模型在住院患者跌倒风险预测中的应用效果,比较不同算法模型的预测性能,并分析影响模型表现的关键因素。

方法

本研究收集1065例住院患者的数据,数据包含基础临床特征(年龄、BMI、病史)、治疗相关变量(药物使用、护理措施)及环境因素(陪护情况、跌倒发生地点等)。跌倒风险水平被标注为二分类变量。数据预处理包括缺失值填充、特征标准化及类别变量编码。数据集按照8:2分为训练集和测试集,采用交叉验证训练模型,并计算模型的准确率、灵敏度、特异性及曲线下面积评估其性能。

结果

在所有模型中,深度神经网络在跌倒风险预测中表现最佳,达到0.78的准确率、0.85的敏感性和0.71的特异性,均高于其他几种算法,其在高维数据中强大的特征提取能力,能够更有效地捕捉复杂的临床特征模式。

结论

深度神经网络在住院患者跌倒风险预测中优于传统机器学习方法,尤其在高风险患者识别方面表现突出。合理选择特征变量、优化数据预处理方法有助于提升模型的预测能力。未来需要多中心大样本研究进一步验证模型的泛化能力,并探索其在不同临床场景下的实际应用价值。

目的

探讨基于机器学习模型在住院患者跌倒风险预测中的应用效果,比较不同算法模型的预测性能,并分析影响模型表现的关键因素。

方法

本研究收集1065例住院患者的数据,数据包含基础临床特征(年龄、BMI、病史)、治疗相关变量(药物使用、护理措施)及环境因素(陪护情况、跌倒发生地点等)。跌倒风险水平被标注为二分类变量。数据预处理包括缺失值填充、特征标准化及类别变量编码。数据集按照8:2分为训练集和测试集,采用交叉验证训练模型,并计算模型的准确率、灵敏度、特异性及曲线下面积评估其性能。

结果

在所有模型中,深度神经网络在跌倒风险预测中表现最佳,达到0.78的准确率、0.85的敏感性和0.71的特异性,均高于其他几种算法,其在高维数据中强大的特征提取能力,能够更有效地捕捉复杂的临床特征模式。

结论

深度神经网络在住院患者跌倒风险预测中优于传统机器学习方法,尤其在高风险患者识别方面表现突出。合理选择特征变量、优化数据预处理方法有助于提升模型的预测能力。未来需要多中心大样本研究进一步验证模型的泛化能力,并探索其在不同临床场景下的实际应用价值。

Fall risk assessment is of significant importance in the elderly population as falls constitute a primary cause of injuries and fatalities among the elderly. This paper comprehensively outlines the commonly used algorithms and classification features in fall risk assessment tools constructed using machine learning techniques. By comparing the performance of these models on real-world datasets, it delves into the strengths and weaknesses of various algorithms and their applicable scenarios. The article provides detailed insights into the data prepossessing steps and model construction processes commonly employed in each model, offering a comprehensive comparison. In conclusion, the paper summarizes the current shortcomings in research and anticipates potential directions for future developments in this field.
