大多数急诊室的访问风险低,可以转向替代护理途径. 根据入院风险分类国际疾病统计分类第十版 (ICD-10) 代码,有助于确定适合这些途径的患者.
科学领域:
- 紧急医疗 紧急医疗
- 医疗保健服务研究 医疗服务研究
- 在医疗保健中的数据科学.
背景情况:
- 优化医院前紧急护理资源分配至关重要.
- 将非紧急的急诊室 (ED) 访问重定向到替代护理服务途径 (ACSP) 可以提高效率.
- 通过使用诊断代码根据入院风险对ED表现进行分层是识别适合ACSP的患者的潜在方法.
研究的目的:
- 根据医院入院风险对国际疾病统计分类第十版 (ICD-10) 诊断代码进行聚类.
- 确定与这些入院风险集群相关的ED表现的特征.
- 开发一个探索性分类系统,以确定潜在适合ACSP的患者群体.
主要方法:
- 从第三级护理机构的ED数据库 (2016-2020年) 中分析了回顾性观察数据.
- 根据住院结果对ICD-10诊断代码进行了K-means集群.
- 多变量逻辑回归用于评估患者特征与集群成员身份之间的关联.
主要成果:
- 从215477次访问中,根据入院风险确定了四个不同的ED表现集群.
- 集群1 (61%的访问) 的入学率最低 (4.7%),而集群4 (5.5%的访问) 的入学率最高 (78%).
- 较高的查尔森并发症指数得分,高心率,高热,最近的手术和最近的住院住院患者与更高风险集群成员的几率增加有关.
结论:
- 大多数门诊性ED病例属于低风险群体,入院的可能性很低.
- 根据入院结果和频率对ICD-10诊断代码进行分层,为风险分层提供了一个结构化的方法.
- 这种方法可以帮助识别适合转向ACSP的患者,从而优化紧急护理资源.

Specialized Care Centers and Settings-II
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
