Ever wonder what syndromic surveillance is? How it is applied? This introduction to syndromic surveillance answers your questions and gives you a foundation for understanding how surveillance is used by public health professionals to understand health threats.
This video introduces the viewer to the basics of syndromic surveillance and offers a high-level overview of the many uses of this public health tool. Topics covered in this training include:
A comprehensive definition of a syndrome is composed of direct (911 calls, emergency departments, primary care providers, sensor, veterinary, agricultural and animal data) and indirect evidence (data from schools, drug stores, weather etc.). Syndromic surveillance will benefit from quickly integrating such data. There are three critical areas to address to build an effective syndromic surveillance system that is dynamic, organic and alert, capable of continuous growth, adaptability and vigilance: (1) timely collection of high quality data (2) timely integration and analysis of information (data in context) (3) applying innovative thinking and deriving deep insights from information analysis. In our view there is excessive emphasis on algorithms and applications to work on the collected data and insufficient emphasis on solving the integration challenges. Therefore, this paper is focused on information integration.
Objective
EII is the virtual consolidation of data from multiple systems into a unified, consistent and accurate representation. An analyst working in an EII environment can simultaneously view and analyze data from multiple data sources as if it were coming from one large local data warehouse. This paper posits that EII is a viable solution to implement a system covering large areas and disparate data sources for syndromic surveillance and discusses case studies from environments external to health.
A review of the development of veterinary syndromic surveillance in 2011 indicated that the field was incipient, but fast growing. Many countries are starting to explore different sources of data for syndromic surveillance. Some of the data streams evaluated share similarities with those used in public health syndromic surveillance, such as clinical records and laboratory data. However, many unique animal data sources have arisen, such as abattoir and carcass collection data. We suggest there are three main challenges in the current development of animal syndromic surveillance: The lack of standards in disease classification; The development of statistical methods appropriate to deal with animal data; The creation of ready-to-use tools that employ these statistical methods.
Objective
To summarize the challenges in the development of syndromic surveillance tools in veterinary medicine, and describe the development of an R package to address some of the current gaps.
Air pollution is well documented to cause adverse health effects in the population. Epidemiological/toxicological studies have demonstrated that air pollution is associated with various adverse health outcomes, ranging from mortality to subclinical respiratory symptoms. Classical epidemiological studies of the health effects of air pollution are typically retrospective. In order to assess the effectiveness of any public health messages or interventions in a timely manner there is a need to be able to systematically detect any health effects occurring in real-time. The UK syndromic surveillance systems are coordinated by Public Health England (PHE) and are used to monitor infectious diseases in real-time. This study is the first in the UK to explore whether syndromic surveillance systems can detect public health impacts associated with air pollution events.
Objective: This study examined whether the current UK real-time syndromic surveillance systems can detect public health impacts associated with air pollution events such as fires and ambient air pollution episodes.
Co-financed by the European Commission through the Executive Agency for Health and Consumers, the European Triple-S project (Syndromic Surveillance Survey, Assessment towards Guidelines for Europe) was launched in 2010 for a 3-year period and includes 24 organizations in 13 countries. Numerous European countries have created SyS systems. These systems analyze and report their SyS findings to local, regional or national public-health authorities in accordance with their national priorities. But the country outputs are not systematically reported and compared at the EU level, hindering a global overview and interpretation of the health situations observed in different regions or countries in Europe. The Triple-S project has thus proposed a strategy for coordinating the comparison and interpretation of SyS information across Europe to produce a Europe-wide epidemiological picture of a given health event in a timely manner, and thereby support coordinated public-health action.
Objective
To present a proposal for coordinating syndromic surveillance (SyS) systems operated by European countries and for comparing findings from these systems.
Syndromic surveillance has great advantages in promoting the early detection of infectious disease outbreak and enabling the real-time tracking of on-going epidemics. However, establishing a syndromic surveillance system required huge investment in money, information system, manpower and capacity building activities, which remains a big challenge in resource-limited areas. Funded by European Union's 7th Framework Programme, a syndromic surveillance system named 'ISSC' was prepared to be built and incorporated with the existing case report system in rural Jiangxi Province of China.
Objective
Before the start of ISSC project, a pilot investigation was carried out among the candidate surveillance units (health care facility, pharmacy and primary school) and related stakeholders to assess their capacity and potential needs with regard to the implementation of ISSC system, so as to design customized capacity building and training strategies.
The CDC's BioSense 2.0 system is designed with a user-centered approach, where the needs and requests of the users are part of its continued development. User requirements were gathered extensively to help design BioSense 2.0 and users continue to submit feedback which is used to make improvements to the system. However, in order to ensure that these needs are gathered in a formal and ongoing way, the BioSense 2.0 Governance Group, comprised primarily of state and local public health representatives, was established to advise the CDC on the development of BioSense 2.0. The Governance Group (GG) understands that to make recommendations having direct relevance and utility to the community, they must engage public health jurisdictions which use BioSense 2.0. To that end, the GG has conducted three surveys of the BioSense 2.0 community. The survey results will help inform the group's prioritized recommendations to the CDC.
Objective
In this presentation we discuss the findings and lessons learned from these surveys.
National telephone health advice service data have been investigated as a source for syndromic surveillance of influenza-like illness and gastroenteritis . Providing a high level of coverage, the system might serve as an early outbreak detection tool. We have previously found that telephone triage service data of acute gastroenteritis was superior to web queries as well as over-the-counter pharmacy sales of anti-diarrhea medication to detect large water- and foodborne outbreaks of gastrointestinal illness in Sweden during the years 2007â2011 (4). However, information is limited regarding the usefulness, characteristics, and signal properties of local telephone triage data for monitoring and identifying outbreaks at the community level.
Objective
Our aim was to use telephone triage data to develop a model for community-level syndromic surveillance that can detect local outbreaks of acute gastroenteritis (AGE) and influenza-like illness (ILI) and allow targeted local disease control information.
