“…2SE FAG (table 1) was set up in French Guiana to complement the mandatory surveillance system, which was used as the reference during the final evaluation of the system [7]. This system is based on two independent networks working together: a recording network, situated in French Guiana, and an analysis network, situated in both French Guiana and mainland France.…”

Proposal of a framework for evaluating military surveillance systems for early detection of outbreaks on duty areas

BackgroundIn recent years a wide variety of epidemiological surveillance systems have been developed to provide early identification of outbreaks of infectious disease. Each system has had its own strengths and weaknesses. In 2002 a Working Group of the Centers for Disease Control and Prevention (CDC) produced a framework for evaluation, which proved suitable for many public health surveillance systems. However this did not easily adapt to the military setting, where by necessity a variety of different parameters are assessed, different constraints placed on the systems, and different objectives required. This paper describes a proposed framework for evaluation of military syndromic surveillance systems designed to detect outbreaks of disease on operational deployments.MethodsThe new framework described in this paper was developed from the cumulative experience of British and French military syndromic surveillance systems. The methods included a general assessment framework (CDC), followed by more specific methods of conducting evaluation. These included Knowledge/Attitude/Practice surveys (KAP surveys), technical audits, ergonomic studies, simulations and multi-national exercises. A variety of military constraints required integration into the evaluation. Examples of these include the variability of geographical conditions in the field, deployment to areas without prior knowledge of naturally-occurring disease patterns, the differences in field sanitation between locations and over the length of deployment, the mobility of military forces, turnover of personnel, continuity of surveillance across different locations, integration with surveillance systems from other nations working alongside each other, compatibility with non-medical information systems, and security.ResultsA framework for evaluation has been developed that can be used for military surveillance systems in a staged manner consisting of initial, intermediate and final evaluations. For each stage of the process parameters for assessment have been defined and methods identified.ConclusionThe combined experiences of French and British syndromic surveillance systems developed for use in deployed military forces has allowed the development of a specific evaluation framework. The tool is suitable for use by all nations who wish to evaluate syndromic surveillance in their own military forces. It could also be useful for civilian mobile systems or for national security surveillance systems.

“…Typical systems in the USA include the multilayered, multidepartment, multifunctional, nationwide, and highly networked Laboratory Response Network (LRN) for biothreats, BioWatch and BioSense programs, and syndromic surveillance system. Other such systems are the French 2SE FAG system, British military prototype remote illness and symptom monitor (PRISM), Australian sentinel practice research network (ASPREN), and Canadian global public health intelligence network (GPHIN) [4][5][6][7]. Moreover, in recent years, the USA and other Western countries have focused on the development of active surveillance systems based on continuous improvement of passive surveillance systems.…”

“…The USA and other Western countries are far ahead in this field, and a variety of management platforms for biosurveillance and early warning systems have been put into use and are being continuously improved, thereby representing the development trend of platforms for biothreat emergency management and comprehensive command. Such systems include HPAC, EpiSimS, BioWar, GLEaMviz, NARAC, ARGOS, and others [11][12][13]. These platforms, crucial technical equipment with high technological sensitivity, which Western countries will not supply to China, are largely developed under the leadership of the military or security agencies.…”

Surveillance and early warning are key aspects of a country's biosecurity capability. In this paper, we investigate the overall status of the USA and other countries' research and development regarding their own capabilities for biosurveillance. We make several recommendations to strengthen China's biosurveillance capability, including strategic planning, mechanism reform, personnel training, and infrastructure platform construction. In addition, we comment on strengthening the supporting role of science and technology.

“…transport delay of the sample to the laboratory) 5 . While delays originating from the former cannot be reduced, analyses may be hindered by delays in case reporting decreasing the overall timeliness and usefulness of the early-warning surveillance systems 6 . Reporting delays depend, among other things, on statutory reporting regulations; on whether an electronic reporting system is in place; on the disease(s) under surveillance (whose identification process may be more or less complex); and on reporting units (e.g.…”

Delayed reporting of health data may hamper the early detection of infectious diseases in surveillance systems. Furthermore, combining multiple data streams, e.g. aiming at improving a system’s sensitivity, can be challenging. In this study, we used a Bayesian framework where the result is presented as the value of evidence, i.e. the likelihood ratio for the evidence under outbreak versus baseline conditions. Based on a historical data set of routinely collected cattle mortality events, we evaluated outbreak detection performance (sensitivity, time to detection, in-control run length) under the Bayesian approach among three scenarios: presence of delayed data reporting, but not accounting for it; presence of delayed data reporting accounted for; and absence of delayed data reporting (i.e. an ideal system). Performance on larger and smaller outbreaks was compared with a classical approach, considering syndromes separately or combined. We found that the Bayesian approach performed better than the classical approach, especially for the smaller outbreaks. Furthermore, the Bayesian approach performed similarly well in the scenario where delayed reporting was accounted for to the scenario where it was absent. We argue that the value of evidence framework may be suitable for surveillance systems with multiple syndromes and delayed reporting of data.
