机器学习模型可以预测老年人紧急住院的情况. 药物负担指数,流动性和跌倒等关键风险因素得到了验证,指导了未来的老年护理干预措施.
科学领域:
- 老年医学 老年医学
- 医疗信息学 医疗信息学
- 临床流行病学临床流行病学
背景情况:
- 机器学习 (ML) 模型对于预测医疗保健中的临床结果至关重要.
- 提高ML模型的准确性,可概括性和可解释性是临床采用的关键.
- 在不同人群中验证ML识别的风险因素对于广泛的临床实践至关重要.
研究的目的:
- 训练和测试三种ML模型 (随机森林,XGBoost,后勤回归),以预测老年人30天的紧急住院治疗.
- 在这个人口群体中,识别和验证导致紧急住院的关键风险因素.
- 为未来的ML研究和 geriatrics的有针对性的干预措施的发展提供信息.
主要方法:
- 来自英国生物银行数据库的86,870名社区老年人 (≥65岁) 的队列研究.
- 使用人口统计数据,老年综合征,并发症和药物负担指数 (DBI) 作为模型变量.
- 通过使用接收器操作特征曲线下的面积 (AUC-ROC) 和F1分数来评估模型性能.
主要成果:
- XGBoost模型实现了最高的AUC-ROC (0.86),其次是随机森林 (0.78) 和后勤回归 (0.61).
- 对30天紧急住院的验证风险因素包括药物负担指数 (DBI),移动性问题,骨折,跌倒,危险的酒精消费和吸烟.
- 这些经过验证的因素表明,紧急住院治疗的预测能力显著.
结论:
- 成功验证了预测老年人30天紧急住院治疗的重要风险因素.
- 这种验证将指导未来的老年医学ML研究,重点是可概括和可解释的模型.
- 根据验证的风险因素优先考虑干预措施,可以改善患者的治疗结果,并减少医疗保健负担.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
