概括
这项研究开发了一个基于代理的模型,使用电子医疗记录来评估ICU中的感染预防和控制 (IPC) 干预措施. 改善手部卫生和消毒可以显著减少感染,但传输参数的数据对于准确的建模至关重要.
科学领域:
- 计算流行病学计算流行病学
- 传染病建模传染病模型
- 与医疗保健相关的感染
背景情况:
- 预防和控制感染 (IPC) 干预措施的临床试验成本高昂,结果不尽相同.
- 数学模型提供了一个具有成本效益的替代方案,但在医院传染中与机构和患者群体的变异性作斗争.
- 基于代理的模型 (ABM) 可以模拟复杂的传输动态.
研究的目的:
- 开发和应用一种基于代理物的模型 (ABM),用于模拟重症监护室 (ICU) 中的病原体传播.
- 通过使用电子医疗记录 (EMR) 数据,估计IPC干预措施在当地医院水平的影响.
- 确定传输建模中的关键不确定性来源,以优先考虑数据收集.
主要方法:
- 开发了一个基于代理的模型 (ABM),集成来自第三级护理医院重症监护室电子病历 (EMR) 的数据.
- 在患者,医疗保健工作者 (HCW) 和医院环境中模拟病原体传播动态.
- 应用该模型来评估各种IPC干预措施的潜在有效性.
主要成果:
- 模型确定了入院患病率,手部卫生遵守/有效性和环境消毒有效性的不确定性,作为感染随机性的主要驱动因素.
- 如果从70%提高到95%,可以减少36%的感染.
- 将终端室消毒效率从50%提高到95%,可以减少31%的感染;将残留污染减少到1%可以减少26%的感染.
结论:
- 与EMR数据集成的in-silico传输模型增强了IPC干预措施的评估.
- 为了减少模型预测中的不确定性,需要收集有关流行病学和操作参数的数据.
- 数据收集的关键领域包括入院患病率,手部卫生效率和环境消毒效率.

Healthcare Associated Infections II: Preventive Measures
2.4K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Methods of Documentation VII: EMR
824
Electronic Medical Records (EMRs) primarily center around electronically documenting patients' health information within a single healthcare organization or practice. They contain essential clinical data related to a patient's medical history, diagnoses, medications, treatment plans, lab results, and other pertinent information relevant to the specific encounter or episode of care. EMRs are designed to streamline documentation and workflow processes within individual healthcare...
