介绍
社区流行病早期通报电子监测系统（ESSENCE II）是一个原型综合征监测系统，用于捕获和分析公共卫生指标，以便早期发现疾病爆发。
目标
本文提出了一个初步评估的ESSENCE II根据疾病预防控制中心评估症状监测系统的框架。
方法
框架的每个主要主题都在ESSENCE II性能评估中进行了讨论。
结果
ESSENCE以多种格式捕获数据，将文本字符串解析为综合征分组，并应用多种时间和时空爆发检测算法。在最近的DARPA评估演习中，ESSENCE算法检测到一组健康事件，在最早可能的检测机会之后，平均延迟1天。
结论
ESSENCE II在该框架方面提供了出色的性能，并已被证明是一种有用且具有成本效益的方法，可用于早期发现健康事件。
INTRODUCTION
The Electronic Surveillance System for the Early Notification of Community-Based Epidemics (ESSENCE II) is a prototype syndromic surveillance system for capturing and analyzing public health indicators for early detection of disease outbreaks.
OBJECTIVES
This paper presents a preliminary evaluation of ESSENCE II according to a CDC framework for evaluating syndromic surveillance systems.
METHODS
Each major topic of the framework is addressed in this assessment of ESSENCE II performance.
RESULTS
ESSENCE captures data in multiple formats, parses text strings into syndrome groupings, and applies multiple temporal and spatio-temporal outbreak-detection algorithms. During a recent DARPA evaluation exercise, ESSENCE algorithms detected a set of health events with a median delay of 1 day after the earliest possible detection opportunity.
CONCLUSIONS
ESSENCE II has provided excellent performance with respect to the framework and has proven to be a useful and cost-effective approach for providing early detection of health events.
