机器学习模型准确地预测了在六个月内养老院居民的跌倒情况. 一个开发出来的诺米图表有助于临床实践,增强了患者的安全和护理协议.
科学领域:
- 老年学是指老年学的学科.
- 医疗保健中的人工智能
- 临床预测模型临床预测模型
背景情况:
- 跌倒是养老院居民的一个重要问题,导致伤害和降低生活质量.
- 准确的跌倒风险评估对于实施预防策略至关重要.
研究的目的:
- 开发和验证一种机器学习 (ML) 模型,用于预测 ambulatory 护理院居民的跌倒情况.
- 创建一个用户友好的工具,让员工在6个月的时间内评估跌倒风险.
主要方法:
- 一项前性队列研究,涉及中国864名养老院居民.
- 收集了潜在跌倒预测因素的数据,包括平衡,握力,疲劳,跌倒史,年龄和并发症.
- 通过使用ROC-AUC和PR-AUC指标评估了七个ML算法 (LR,GBM,XGBoost,RF,SVM,NN,DT).
主要成果:
- 确定了六个关键预测因素:平衡,握力,疲劳,跌倒史,年龄和并发症.
- 在ML模型中,ROC-AUC值在0.710-0.750之间,PR-AUC值在0.415-0.473.3之间.
- 一个物流回归 (LR) 模型被成功转换为临床名录.
结论:
- 基于ML的模型在识别养老院居民中高风险的人群中表现出有效性.
- 开发的名图为改善临床环境下下降风险评估提供了一个实用的工具.
- 这种工具的整合可以提高养老院的患者安全和护理质量.
